Description
Technical Field
The invention relates to the field of ceramic tile film sticking equipment, in particular to a film roll traction and extraction device with double supporting rollers for supporting films.
Background
In the packaging process of the tiles after production, the tiles are required to be stacked and packaged, and the stacked tiles are easy to squeeze and rub in the transportation process, so that the surfaces of the tiles are worn and broken. In order to avoid the phenomenon, a plurality of existing machines are used for pasting films on the ceramic tiles, so that the ceramic tiles are isolated from each other, the surfaces of the ceramic tiles are prevented from being scratched by friction, and meanwhile impurities are prevented from scratching the surfaces of the ceramic tiles.
As shown in fig. 1, in a drawing-out device in a conventional tile laminating apparatus, a film is wound around a transition roller 3 and is bonded to a tile 5 by a tile press roller 4. The tile press roller 4 not only has a compacting effect on the fitting of the film and the tile 5, but also is the power for drawing the film discharging device. The left view of the existing film roll supporting structure is shown in fig. 2, the supporting shaft 2 penetrates through the film roll 1, one side of the supporting shaft is fixed on the fixed supporting plate 8, the other side of the supporting shaft is not fixed, and the supporting shaft is limited only by the movable supporting plate 6. When the film roll 1 is replaced, the movable supporting plate 6 is removed, the clamping block 7 is pulled out, the clamping block 7 is screwed down after the film roll 1 is sleeved, and then the movable supporting plate 6 is installed.
As shown in fig. 2, the conventional film roll supporting structure is only fixed at one side, and is affected by the dead weight of the film roll 1, and the supporting shaft 2 is inclined to a certain extent, so that the deviation of parallelism between the film and the brick surface is large, and the film sticking effect is poor, and wrinkles and bubbles are many. The existing film roll supporting structure has relatively complex operation and high labor intensity when the film roll 1 is replaced. The existing traction film-discharging device drives the tile press roller 4 to move when the tile 5 moves, so that the tile press roller 4 provides power for traction film-discharging device, thus, the film is acted by a certain tension, after the film is cut off, the tension disappears, and the film is contracted to form wrinkles at the fracture easily. Since the tile 5 is stationary during the film cutting process, the rotation of the tile press roll 4 is actually intermittent, and when the tile press roll 4 suddenly stops rotating, the film roll 1 continues to rotate due to inertia, so that the pulled film is too much, and the film is inconvenient to spread and flatten, and bubbles and wrinkles are formed after the film roll is attached to the tile 5.
Patent application number CN200820135413.0 discloses a film supply structure for preparing a unidirectional prepreg tape, comprising: a film roll comprising a spool and a film wound on the spool, the film having an open end; a bracket; a first support roller horizontally mounted on the bracket; and a second support roller mounted on the bracket and parallel to the first support roller. The width of a gap between the first support roller and the second support roller is not more than the diameter of the scroll, and the angle between the central axis connecting line of the first support roller and the central axis connecting line of the second support roller and the horizontal line is smaller than 45 degrees; the roll of film is placed over the slit with the release end passing through the slit. The film supply structure provided by the invention enables the process of replacing the film winding drum to be simple and feasible, and can improve the working efficiency. And further provides clamping members mounted on the first support roller for clamping the two ends of the film roll, so that the position of the film roll can be adjusted to position the film roll. The clamping member in this patent need dismantle clamping member and spool when changing the film reel, makes to change inconvenient, and when setting up clamping member, only one in first backing roll and the second backing roll is rotatable rod moreover, can produce certain friction damage to the surface of film in the use.

The telescopic rod can adjust the distance between the left baffle rod 13 and the right baffle rod according to the film rolls 1 with different widths, so that the left baffle rod 13 and the right baffle rod can be ensured to limit the positions of the film rolls 1, and the film rolls 1 are prevented from moving along the axial direction.
Example 7
This embodiment only describes differences from the above-described embodiment, and the remaining technical features are the same as those of the above-described embodiment. As shown in fig. 6, the rotating mechanism comprises a rotating arm 16, a fixed shaft 17 and a cylinder 18, wherein the fixed shaft 17 comprises a first fixed shaft 171 and a second fixed shaft 172, the first fixed shaft 171 is fixed between the left support plate 14 and the right support plate 15, one end of the rotating arm 16 is connected with the first fixed shaft 171, and the other end of the rotating arm 16 is rotatably connected with the circumferential side wall of the side roller 12; the rotating arm 16 is provided with a connecting end 161, the connecting end 161 is connected with a cylinder 18, the cylinder 18 is used for pushing the rotating arm 16 to rotate around a first fixed shaft 171, the bottom of the cylinder 18 is fixed on a second fixed shaft 172, and the second fixed shaft 172 is fixed between the left support plate 14 and the right support plate 15.
The power of the film pulling device for supporting the film roll by the double-support roller is directly provided by the transition roller 3, the tile press roller 4 is connected with the transition roller 3 by the synchronous belt 11, synchronous rotation is ensured, the tile press roller 4 is driven to rotate when the tile 5 runs, and meanwhile, the transition roller 3 is driven to rotate by the synchronous belt 11; the ceramic tile press roll 4 can press the film on the transition roll 3, and the film is pulled out through the rotation of the transition roll 3; the compression roller only has the compaction effect on the lamination of the ceramic tile 5 and the film, separates the original functions of film pulling and film pasting of the ceramic tile compression roller 4, improves the folds and bubbles of the film caused by tension, intermittent film pasting and the like, and improves the film pasting quality. The film pulling device for pulling the film roll supported by the double carrier rollers divides the pulled film into two parts, and the part of the film in front of the transition roller 3 is a film pulling section; the film between the transition roller 3 and the tile press roller 4 is not stressed by tension, and meanwhile, the stress of the section of film is not influenced by the movement, stop and other conditions of the tile press roller 4, so that the film pasting process is more stable. When the tile press roller 4 suddenly stops rotating, the film roll 1 can continue rotating due to inertia, so that the pulled films are too much, inconvenient to spread and flatten, and bubbles and wrinkles can be formed after the film roll is attached to the tile 5. The film roll supporting structure in the double-support-roller supporting film roll traction film leading-out device adopts the double support rollers 9 for supporting, and the left stop rod 13 and the right stop rod 131 at two sides of the film roll 1 can limit the film roll 1. Compared with the existing structure, the double-support roller 9 supports and ensures that the film roll 1 is always in the horizontal position, and film lamination folds and bubbles caused by the dead weight of the film roll 1 are improved.
Variations and modifications to the above would be obvious to persons skilled in the art to which the invention pertains from the foregoing description and teachings. Therefore, the invention is not limited to the specific embodiments disclosed and described above, but some modifications and changes of the invention should be also included in the scope of the claims of the invention. In addition, although specific terms are used in the present specification, these terms are for convenience of description only and do not constitute any limitation on the invention.
