AI Technical Summary
Existing Velcro unwinding mechanisms tend to cause the fabric roll to become tangled and unable to maintain tension during unwinding, affecting subsequent cutting processes.
By employing a combination design of pressure rollers and tension rollers during the unwinding process, the pressure rollers press the Velcro fabric roll tightly during unwinding, while the tension rollers move synchronously with the unwinding process to maintain the tension of the fabric roll. The baffles increase resistance to ensure the stability of unwinding.
It achieves stability of the Velcro roll during unwinding, prevents it from scattering, and ensures smooth subsequent cutting. The tension is maintained through the cooperation of the pressure roller and the tension roller, and the baffle increases resistance to quickly stop unwinding.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of magic tape production, in particular to the technical field of magic tape unwinding mechanism. BACKGROUND
[0002] Magic tape is a kind of commonly used connecting auxiliary material on clothes, which is divided into two sides, one side of magic tape is fine and soft fiber, round hair, and the other side is relatively hard hooking hair.
[0003] In the production process of magic tape, the magic tape needs to be unwound, and then cut, the existing unwinding mechanism is easy to scatter the cloth roll of magic tape when unwinding, and as the cloth roll gradually decreases, it is difficult to ensure that the unwound cloth is in a tension state, which will affect the subsequent cutting. SUMMARY
[0004] The utility model discloses a magic tape unwinding mechanism, which can solve the above problems.
[0005] To achieve the above-mentioned purpose, the utility model provides a kind of magic tape unwinding mechanism, including unwinding frame, unwinding roller, lifting plate, mounting bracket, compression roller, connecting rod, tension bracket and tension roller, unwinding frame is rotatably installed with unwinding roller, and unwinding roller is equipped with magic tape cloth roll, the top of unwinding roller is equipped with lifting plate, and lifting plate is connected with lifting mechanism, the bottom of lifting plate is equipped with mounting bracket, the mounting bracket is rotatably installed with compression roller, the lower surface of compression roller is compressed with the upper surface of magic tape cloth roll, the front of mounting bracket is equipped with connecting rod, and connecting rod is fixedly installed with lifting plate, the bottom of connecting rod is equipped with tension bracket, and tension bracket is rotatably installed with tension roller.
[0006] As a preferred, the connecting rod is a telescopic rod.
[0007] As a preferred, the rear of mounting bracket is rotatably installed with baffle, and the surface of baffle is abutted with the surface of magic tape cloth roll.
[0008] As a preferred, the both sides of baffle are equipped with connecting lug, and mounting bracket or lifting plate is equipped with fixed lug, and connecting lug and fixed lug are connected by tension spring.
[0009] As a preferred, the lifting mechanism is lifting cylinder.
[0010] The beneficial effects of this utility model are as follows: By setting up a pressure roller and a synchronously moving tension roller, the pressure roller keeps the hook and loop fastener pressed down during unwinding to prevent it from scattering; as the fabric roll decreases, the tension roller moves downwards synchronously with the pressure roller, keeping the unwound hook and loop fastener taut and ensuring smooth subsequent cutting; by setting up a baffle, the resistance to unwinding is increased, making the unwinding process more stable, and the rotation of the unwinding roller can be quickly stopped after unwinding stops.
[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description
