Description
Technical field
The present invention relates to a kind of pay off rack, especially a kind of Constant-tension pay-off rack.
Background technology
At wires and cables industry, transformator and knit and spin in industry, all need to use pay off rack. Existing pay off rack is unable to keep a stable tension force, often neglects tight pine suddenly, causes the factors of instability to product quality. Chinese patent literature CN201773697U discloses a kind of coil paying-off former, it is that brake is set on the side of drum, pay off rack is provided with the cylinder supporting with drum and wire-crossing wheel, provides different identical tension by the brake controlling to be connected from precision adjustment valve according to not collinear rule. Owing to its tension force is the dual function by brake and wire-crossing wheel cylinder, and the different pressure that line is produced of Telescopic-cylinder degree is different (if the air pressure in cylinder does not change, during Telescopic-cylinder, pressure is constant), tension force can only be made relatively stable in certain scope, it is impossible to realize constant and accurate setting. Chinese patent literature number is the dancer reaction type yarn tension control device of disposable warping machine disclosed in CN103010838A, it it is increase dancer feedback mechanism between beam of a loom drive mechanism and Yarn traction mechanism, speed controling signal as the beam of a loom frequency conversion motor of beam of a loom drive mechanism, it is achieved haulage gear frequency conversion motor is harmonious with beam of a loom frequency conversion motor. This scenario-frame is complicated, is furnished with motor, loss electric energy, and owing to being control frequency conversion motor rotating speed again through feedback device after yarn tension changes, system delayed more, and tension force is in small size real-time change state in fact. Said apparatus is all that the tension force for thinner and relatively soft line controls, and owing to the winding cable such as transformator, reactor wants thick many and relatively hard, therefore aforementioned actinobacillus device is inapplicable for the conductor cable identical tension unwrapping wire of transformator, reactor etc.
Summary of the invention
It is an object of the invention to propose a kind of Constant-tension pay-off rack, it is possible to realize cable strain during unwrapping wire constant, and tension force can be presetting, and simple in construction, it is possible to meet the cable identical tension unwrapping wire requirement such as transformator, reactor.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described, to help understanding present disclosure.
Preferred embodiment one
As shown in Figure 1 to Figure 3, a kind of Constant-tension pay-off rack of the present invention, including the roll 2 being arranged in frame 1, reel 3 is installed in the side of roll 2, and when roll 2 rotates, reel 3 is driven synchronous axial system by roll 2. The opposite side of roll 2 installs brake 8.
Being additionally provided with pressure roller shaft 6 in frame 1, roller arm group 5 and pressure roller handle 13, opposite side setting angle sensor 7 are installed in the side of pressure roller shaft 6. Pressure roller shaft 6 is circular shaft, first roller arm 51 and second roller arm 52 one end are enclosed within pressure roller shaft 6, first roller arm 51 and the second roller arm 52 are provided with the screw matched with jackscrew 12 with pressure roller shaft junction, pressure roller shaft is provided with the locating slot coordinated with jackscrew, jackscrew 12 end in screw embeds in locating slot, to prevent roller arm and pressure roller shaft from relatively rotating, the first roller arm and the second roller arm other end connect pressure roller 4. Jackscrew 12 top is provided with jackscrew handle 121, in order to without the free-hand stubborn jackscrew of instrument. Being additionally provided with pressure roller handle 13 near frame 1 position arranging roller arm group 5 side, pressure roller handle 13 is connected for fixing with pressure roller shaft 6, in order to lifts pressure roller when changing reel 3 and puts down pressure roller 4.
The first roller arm 51 head in roller arm group 5 is provided with elbow, make two roller arms near time, the pressure roller 4 on the second roller arm 52 will not with first roller arm 51 produce interfere. " u "-shaped position limit arm 53 seals that one end is fixing with the first position limit arm 51 to be connected, and the second roller arm 52 is positioned at the U-type groove mouth of defining arm 53, makes the second roller arm 52 can move left and right in " u "-shaped position limit arm 53.
Frame 1 is also installed controller 9. Angular transducer 7 signal output part is connected with controller 9 signal input part, and controller 9 signal output part is connected with brake 8 signal input part.
Castor 11 is installed bottom frame 1, facilitates the movement of pay off rack.
Concrete operation method one:
Rotate pressure roller handle 13, make roll shaft arm group 5 away from roll 2.Reel 3 center hole is directed at roll 2, and near frame 1, then reel 3 is fixed on roll 2. Rotate pressure roller handle 13, make roll shaft 4 near roll 2. Loosen jackscrew 12, mobile roller arm position in pressure roller shaft, make two pressure rollers 4 away from roll shaft arm side near the inner side of reel 3 wire-blocking board, tighten jackscrew 12. Rotate pressure roller handle 13, make pressure roller 4 be pressed on reel 3 be wound around cable position top.
During unwrapping wire, the cable on reel 3 reduces, and pressure roller 4 is close on line always, makes pressure roller shaft 6 rotate to reduce resistance. Line on reel 3 often reduces one layer, and the height of pressure roller 4 just decline one layer, pressure roller shaft 6 will turn an angle. Angular rate signal is transferred to controller 9 by the angular transducer 7 in pressure roller shaft 6, and controller 9 transmits a signal to brake 8 again. The brake force of roll 6 is changed by brake 8, it is achieved cable strain does not reduce the arm of force with the cable number of plies and shortens and change, and reaches cable pay-off constant tension effect.
Preferred embodiment two
This preferred embodiment and preferred embodiment one are distinctive in that, this preferred embodiment also includes alignment roll shaft group 10.
As shown in Figure 1 to Figure 3,10 groups of alignment roll shaft includes roll shaft support plate 101, roll shaft angle bar 102, roll shaft prop up plate 103 and roll shaft 104. Roll shaft group 10 is positioned at the reel 3 upper end face away from pressure roller shaft side and when being not less than the maximum coiling of reel. Roll shaft support plate 101 is a square iron plate of block length, fixes with the upper angle of frame 1 and is connected. Roll shaft angle bar 102 is fixing with roll shaft support plate 101 one-tenth 90 degree to be connected, and parallel to the ground. Roll shaft angle bar 102 one end is connected with roll shaft support plate 101, and the other end props up with roll shaft that plate 103 is fixing to be connected. Roll shaft support plate 101 and roll shaft prop up and arrange roll shaft 104 between plate 103.
Concrete operation method two such as the concrete operation method one of preferred embodiment one, is distinctive in that the line of releasing is ridden on roll shaft 104 by this operational approach, and that reduces the line that runs out rocks the change with angle.
Preferred embodiment three
With preferred embodiment one or preferred embodiment two, this preferred embodiment is distinctive in that frame 1 can be welded by square steel, channel-section steel, angle bar or its combination, it is also possible to be that other are detachably installed. Roll 2 and the pressure roller shaft 6 position in frame 1 are not limit, and quantity is not limit. Angular transducer 7 installation site is not limit, as long as angular rate signal when roller arm group 5 rotates can be received. The installation site of controller 9 is not limit, as long as the signal of angular transducer 7 output can be accepted, and the output signal of controller 9 can be passed to brake 8. The installation site of brake 8 is not limit, as long as the output signal of controller 9 can be accepted, and controls the torque of roll 2. The installation site of pressure roller handle 13 is not limit, as long as not interfering with other equipment in use. Pressure roller handle 13 and pressure roller shaft 6 can be Split type structure, it is also possible to for integral type structure.
