Description

Technical Field

[0001] The utility model belongs to the technical field of wire-paying devices, and in particular relates to a wire-paying device that prevents excessive stretching. Background Art

[0002] The pay-off device is one of the key components in the production process of enameled wire. Its main function is to provide continuous copper wire while maintaining a certain tension during the production process.

[0003] Chinese patent application number 202022716568.7 discloses a wire winding machine for copper wire, comprising a base plate, a first support plate, a second support plate, a motor, a chute, an arc-shaped card plate, a fixed block, a universal wheel and a screw. The first support plate is fixedly connected to the right side of the top end face of the base plate, the second support plate is fixedly connected to the left side of the top end face of the base plate, and the right end face of the first support plate is fixedly connected to the protective cover. The present application slides the arc-shaped card plate so that the bolts on the mounting block correspond to the positioning holes. The bolts are rotated into the positioning holes to facilitate the fixing of the arc-shaped card plate. At the same time, the arc-shaped card plate drives the sliding sleeve to compress the spring. The motor drives the shaft to rotate, so that the winding roller fixed to the shaft rewinds the copper wire. After the winding is completed, the bolts in the positioning holes are rotated out, so that the compressed spring pushes the arc-shaped card plate to clamp the copper wire on the winding roller through elastic potential energy, thereby preventing the wound copper wire from falling off due to loose winding.

[0004] In the above-mentioned patent disclosure, the tension of the copper wire during operation of the device cannot be controlled. When the tension is too large, the copper wire will be over-stretched, thereby affecting the dimensional accuracy and softness of the copper wire and reducing the quality of the product. When the winding roller is unwinding the copper wire, the direction of the copper wire cannot be controlled, and the copper wire will become disordered on the surface of the winding roller, affecting its use.

[0024] By adopting the above technical solution, the copper wire is passed around the top of the upper roller 62 and then completed around the inner surface of the lower roller 66. The copper wire is S-shaped after passing through the upper roller 62 and the lower roller 66. When the tension sensor inside the pay-off roller mechanism 1 detects that the tension of the copper wire is too large, the adjustment motor 68 is started to drive the screw rod 67 to rotate. Under the meshing connection between the screw rod 67 and the slider 63, the bracket 64 limits the slider 63, and the fixed rod 65 and the slider 63 are slidingly limited. Because the thread directions of the two end surfaces of the screw rod 67 are opposite, the upper roller 62 and the lower roller 66 will move closer to each other, reducing the tension of the copper wire and making the device more effective in preventing over-stretching.

[0025] Specifically, the center of the inner groove of the bracket 64 is flush with the center of the pay-off roller mechanism 1 , and the two sliders 63 are centrally symmetrical about the inner position of the bracket 64 .

The rotating control rod 613 limits the rotation of the control rod 613. Under the meshing connection between the control rod 613 and the lifting plate 614, the connecting rod 611 slides and limits with the bottom plate 3. The lifting plate 614 can drive the two counterweights 5 to move down and land synchronously through the connecting rod 611, which is more convenient to operate. The landing of the counterweight 5 fixes the position of the device. The wire-releasing roller mechanism 1 in the support 2 can retract and release the copper wire, and the pressing mechanism 8 can press the end of the copper wire to prevent it from being loose, so that the copper wire passes around the top of the upper roller 62 and then completes the loop from the inner surface of the lower roller 66. The copper wire passes through the upper roller 62 and the lower roller 66 in an S shape. When the wire-releasing roller machine When the tension sensor inside structure 1 detects that the tension of the copper wire is too large, the adjustment motor 68 is started to drive the screw rod 67 to rotate. Under the meshing connection between the screw rod 67 and the slider 63, the bracket 64 limits the slider 63, and the fixed rod 65 slides and limits with the slider 63. Because the thread directions of the surfaces at both ends of the screw rod 67 are opposite, the upper roller 62 and the lower roller 66 will move closer to each other, reducing the tension of the copper wire and making the device more effective in preventing excessive stretching. The side end control motor 75 of the fixed seat 71 is started to drive the screw rod 72 to rotate. Under the meshing connection between the screw 72 and the moving block 74, the through slot 73 limits the moving block 74, and the moving block 74 can drive the guide ring 76 to move horizontally. The copper wire passes through the guide ring 76 and can be guided by the guide ring 76 to prevent the copper wire from being entangled in the wire-releasing roller mechanism 1, thereby making the device's retraction and release effect better.
