Detailed Description
Referring to fig. 1 and 2, a schematic structure diagram of an embodiment of a cutting machine for paper tube production and an enlarged schematic diagram of a fixing rod and a winding mechanism according to the present invention are shown. As shown in the drawing, the paper tube forming and cutting machine 10 mainly includes a fixing rod 11, a winding mechanism 13, an angle measuring unit 14, a length measuring unit 171, a cutter 151 and a driving mechanism 153, wherein the winding mechanism 13 and the fixing rod receive a paper tape 121, and the paper tape 121 is wound on the fixing rod 11 by the winding mechanism 13 to form a paper tube 123.
The fixing rod 11 is cylindrical or elongated, and the winding mechanism 13 is adjacent to the fixing rod 11, for example, the fixing rod 11 may be fixed on a fixing frame 110, so that the fixing rod 11 cannot rotate or displace relative to the fixing frame 110.
In an embodiment of the invention, the winding mechanism 13 includes a connecting base 131, a driving wheel 133, at least one rotating wheel 135 and a belt 137, wherein the connecting base 131 can be a plate, and the driving wheel 133 and the rotating wheel 135 are disposed on the connecting base 131 and can rotate relative to the connecting base 131. The belt 137 is wound around the driving wheel 133 and the rotating wheel 135, and when the motor drives the driving wheel 133 to rotate, the belt 137 drives the rotating wheel 135 to rotate.
The belt 137 of the winding mechanism 13 is wound around the fixed rod 11, as shown in fig. 2, for example, the driving wheel 133 and the rotating wheel 135 of the winding mechanism 13 may be located below and above the fixed rod 11, respectively, and the belt 137 located between the driving wheel 133 and the rotating wheel 135 is wound around the fixed rod 11. When the driving wheel 133 rotates, the belt 137 will be displaced with respect to the fixing lever 11.
In practical application, at least one paper tape 121 is placed in the gap between the fixing rod 11 and the tape body 137, and the driving wheel 133 rotates to drive the tape body 137 to displace relative to the fixing rod 11, so that the tape body 137 winds the paper tape 121 between the fixing rod 11 and the tape body 137 on the fixing rod 11, and generates a paper tube 123. The paper tube 123 grows along the fixing rod 11 toward the cutter 151 until the driving wheel 133 stops rotating. In the present embodiment, a paper tape 121 is wound around the fixing rod 11 to form the paper tube 123, and in a different embodiment, a plurality of paper tapes 121 are wound around the fixing rod 11 to form the paper tube 123.
In an embodiment of the present invention, the connecting base 131 is connected to the fixing frame 110 and can swing relative to the fixing frame 110. When the connecting base 131 swings relative to the fixing rod 11, the angle of the belt 137 wound around the fixing rod 11 will be changed, so as to adjust the feeding angle of the paper tape 121 relative to the fixing rod 11. The detailed construction of the winding mechanism 13 described above is only one embodiment of the present invention, and is not intended to limit the scope of the claims.
The cutter 151 is adjacent to the fixing rod 11 and is used to cut the paper tube 123 on the fixing rod 11 to form a fixed length of paper tube 123. In an embodiment of the present invention, as shown in fig. 3, the cutter 151 includes a plate 1511, a plurality of cutter wheels 1513 and a plurality of swing arms 1515, wherein each cutter wheel 1513 is connected to the plate 1511 through one swing arm 1515, for example, the number of cutter wheels 1513 may be three.
The plate 1511 is provided with a through hole 1512, the fixing rod 11 and/or the paper tube 123 pass through the through hole 1512 on the plate 1511, and a plurality of knife wheels 1513 are looped around the through hole 1512. The swing arm 1515 may drive the connected blade wheel 1513 to swing relative to the plate 1511, such that the blade wheel 1513 is displaced relative to the through hole 1512, the fixing rod 11, and/or the paper tube 123 on the plate 1511, for example, by driving the swing arm 1515 to swing by a motor. When cutting the paper tube 123, the swing arm 1515 can drive the knife wheel 1513 to move towards the fixing rod 11 and/or the paper tube 123, so as to cut the paper tube 123 on the fixing rod 11. The above detailed configuration of the cutter 151 is only one embodiment of the present invention, and is not intended to limit the scope of the claims.
The cutter 151 is connected to a driving mechanism 153, wherein the driving mechanism 153 is used for driving the cutter 151 to move along the fixing rod 11, for example, the driving mechanism 153 may be a stepper motor. In an embodiment of the present invention, at least one sliding rail 161 may be disposed on the fixing frame 110, and the cutter 151 is connected to the sliding rail 161 through at least one sliding seat 163, and the driving mechanism 153 may drive the cutter 151 and the sliding seat 163 to move along the sliding rail 161 and the fixing rod 11.
In the process of cutting the paper tube 123 by the cutter 151, the direction of the displacement of the cutter 151 driven by the driving mechanism 153 is the same as the length increasing direction of the paper tube 123, wherein the speed of the displacement of the cutter 151 driven by the driving mechanism 153 can be the same as or similar to the length increasing direction of the paper tube 123 in unit time. For example, when the paper tube 123 has a generation speed of 10cm/s, the driving mechanism 153 also drives the cutter 151 to displace along the fixed rod 11 at a speed of 10 cm/s.
Since the displacement speed of the cutter 151 of the present invention is the same as the generation speed of the paper tube 123, the paper tube 123 will not push against the side of the cutter 151 when the cutter 151 cuts the paper tube 123. In contrast, the conventional cutter does not displace relative to the direction of the paper tube when cutting the paper tube, so that the paper tube can squeeze the side edge of the cutter 151 or the cutter 151 pulls the paper tube 123, which not only affects the cutting quality of the paper tube, but also increases the loss rate of the cutter.
To achieve the above object, the present invention calculates the generation speed of the paper tube 123 and adjusts the speed at which the driving mechanism 153 drives the cutter 151 to move. Specifically, the paper tube forming and cutting machine 10 of the present invention includes an angle measuring unit 14 and a length measuring unit 171, wherein the angle measuring unit 14 is used for measuring the angle of the winding mechanism 13 relative to the fixing rod 11 or the feeding angle of the paper tape 121 relative to the fixing rod 11, and the length measuring unit 171 is used for measuring the conveying length of the paper tape 121.
In an embodiment of the present invention, the angle measuring unit 14 may be connected to the winding mechanism 13 or adjacent to the winding mechanism 13, and is used for measuring the inclination angle of the winding mechanism 13, for example, the angle measuring unit 14 may be an inclination angle measuring device.
The winding mechanism 13 and the connecting base 131 can rotate relative to the fixing rod 11, as shown in fig. 1 and 4, to change the angle of the belt 137 wound on the fixing rod 11 and adjust the feeding angle or winding angle of the paper tape 121 wound on the fixing rod 11. Basically, the feeding angle of the paper tape 121 relative to the fixing rod 11 is related to the angle between the winding mechanism 13 and the fixing rod 11, and in the embodiment of the present invention, the feeding angle of the paper tape 121 relative to the fixing rod 11 is calculated by the angle between the winding mechanism 13 and the fixing rod 11.
In another embodiment of the present invention, the feeding angle of the paper tape 121 relative to the fixing rod 11 can be directly measured, as shown in fig. 5, the angle measuring unit 24 can be disposed near the position where the paper tape 121 enters the fixing rod 11, and directly measure the angle between the paper tape 121 and the fixing rod 11, such as the feeding angle of the paper tape 121.
The length measuring unit 171 is disposed upstream of the fixing lever 11 and the winding mechanism 13, and measures the conveyance length of the paper tape 121. In an embodiment of the present invention, at least one conveying wheel 173 may be disposed upstream of the fixing rod 11 and the winding mechanism 13, and the paper tape 121 is conveyed to the fixing rod 11 and the winding mechanism 13 by the conveying wheel 173, wherein the length measuring unit 171 may be connected to one of the conveying wheels 173, and measure the number of rotations of the conveying wheel 173, so as to calculate the conveying length of the paper tape 121.
The generation speed of the paper tube 123 is related to the feeding length of the paper tape 121 and the feeding angle of the paper tape 121 and the fixing rod 11, so that the length of the paper tube 123 increased in unit time can be calculated by measuring the feeding angle and the feeding length of the paper tape 121.
For this reason, when the paper tube 123 is cut by the cutter 151, the speed of the cutter 151 along the fixing rod 11 can be adjusted according to the angle and the conveying length, for example, the displacement speed of the cutter 151 is adjusted according to the generation speed of the paper tube 123, so that the speeds of the two are the same or similar. In different embodiments, the angle between the winding mechanism 13 and the connecting base 131 can be converted into the (feeding) angle between the paper tape 121 and the fixing rod 11, so that the forming speed of the paper tube 123 can be calculated from the angle between the winding mechanism 13 and the connecting base 131 and the conveying length of the paper tape 121.
In practical applications, the circumference and/or radius of the paper tube 123, the width W and/or thickness of the paper tape 121 can be further measured, and the forming speed of the paper tube 123 can be more precisely calculated from the circumference of the paper tube 123, the width W, thickness, feeding angle and conveying length of the paper tape 121, wherein the circumference of the paper tube 123 is related to the circumference of the fixing rod 11, for example, the circumference of the paper tube 123 approximates the circumference of the fixing rod 11.
In addition, the increasing speed of the paper tube 123 may also be related to the winding manner of the paper tape 121, for example, the adjacent paper tapes 121 wound on the fixing rod 11 do not overlap each other, as shown in fig. 6, so that the generating speed of the paper tube 123 can be calculated by the included angle between the winding mechanism 13 and the fixing rod 11, the circumference of the paper tube 123, the width W, the thickness, the feeding angle and/or the conveying length of the paper tape 121, and the speed of the driving mechanism 153 for driving the cutter 151 to move can be adjusted.
In various embodiments, adjacent ribbons 121 wrapped around the rod 11 may overlap, as shown in FIG. 7, such that the ribbons 121 of the resulting tube 123 have an overlapping region 125. In this way, the width of the overlap region 125 needs to be further considered in calculating the paper tube 123 generation speed.
In practice, the paper tube forming and cutting machine 10 may include a computing unit 18, for example, the computing unit 18 may be a computer. The calculating unit 18 is electrically connected to the angle measuring unit 14, the length measuring unit 171 and the driving mechanism 153, and receives the data of the angle and the conveying length from the angle measuring unit 14 and the length measuring unit 171, respectively, to calculate the generating speed of the paper tube 123, and then control the speed of the driving mechanism 153 to drive the cutter 151 to move according to the generating speed of the paper tube 123. In addition, the calculating unit 18 may also receive the radius of the fixing rod 11 and the width of the paper tape 121, and calculate the generating speed of the paper tube 123 according to the angle, the conveying length, the radius of the fixing rod 11 and the width of the paper tape 121.
Specifically, the direction of displacement of the cutter 151 of the cutting machine 10 for paper tube production is the same as the direction of production of the paper tube 123, and in addition, the displacement speed of the cutter 151 is also the same as the growth speed of the paper tube 123, so that the paper tube 123 will not be extruded by the side edge of the cutter 151 or the cutter 151 will pull the paper tube 123 during the process of cutting the paper tube 123 by the cutter 151, thereby effectively improving the cutting quality of the paper tube 123 and prolonging the service life of the cutter 151.
Referring to fig. 8, a flowchart of steps of an embodiment of a paper tube cutting method according to the present invention is shown. Referring to fig. 1, the conveying length of at least one paper tape 121 is measured, and in step 31, the conveying length of the paper tape 121 can be measured by the length measuring unit 171 and the conveying wheel 173.
The paper tape 121 is conveyed to the fixing rod 11 and the winding mechanism 13, as shown in step 33, wherein the paper tape 121 is located in the gap between the fixing rod 11 and the winding mechanism 13, and the paper tape 121 can be driven by the winding mechanism 13.
In step 35, in an embodiment of the present invention, the feeding angle of the paper tape 121 relative to the fixing rod 11 can be directly measured by the angle measuring unit 24. In various embodiments, the permeable angle measuring unit 14 measures the angle between the winding mechanism 13 and the fixing rod 11, and further calculates the feeding angle of the paper tape 121 relative to the fixing rod 11.
The paper tape 121 is wound around the fixing rod 11 to form a paper tube 123, step 37. Specifically, the paper tape 121 may be wound around the fixing lever 11 by the winding mechanism 13 and the paper tube 123 may be formed.
The speed of the cutter 151 along the fixed rod 11 is adjusted according to the conveying length and the feeding angle, as shown in step 39. Specifically, the feeding angle of the paper tape 121 relative to the fixing rod 11 and the conveying length of the paper tape 121 can be used to calculate the generation speed of the paper tube 123, and the displacement speed of the cutter 151 along the fixing rod 11 is the same as or similar to the generation speed of the paper tube 123, so as to improve the cutting quality of the paper tube 123 and the service life of the cutter 151.
In another embodiment of the present invention, the circumference and/or radius of the paper tube 123 or the fixing rod 11 and the width W and/or thickness of the paper tape 121 can be further measured, so that the generation speed of the paper tube 123 and the displacement speed of the cutter 151 can be calculated more precisely from the radius, circumference, width W, thickness, feeding angle and conveying length of the paper tube 123 or the fixing rod 11, and the displacement speed of the cutter 151 along the fixing rod 11 can be adjusted.
In addition, when calculating the forming speed of the paper tube 123, the width of the overlapping area 125 of the adjacent paper strips 121 on the paper tube 123 can be further considered, and the speed of the cutter 151 moving along the fixing rod 11 can be adjusted according to the conveying length, the feeding angle, the radius of the fixing rod 11, the width of the paper strips 121 and the overlapping area 125.
The foregoing description is only one preferred embodiment of the present invention and is not intended to limit the scope of the invention, i.e., all equivalent variations and modifications in shape, construction, characteristics and spirit as defined in the claims are intended to be included in the scope of the present invention.
