[0028] The mounting frame 10 is used to install various components. Those skilled in the art can set different external driving parts according to actual needs to connect with the mounting frame 10, so as to insert the material tape into the winding needle. The clamping mechanism is used to clamp the material tape to ensure the clamping of the subsequent material tape when the material tape is cut, and to insert the subsequent material tape into the winding needle for subsequent winding. Specifically, the clamping mechanism includes a first clamping component 211 and a second clamping component 212. The first clamping component 211 is connected to the mounting frame 10 as a fixed reference for clamping. The second clamping component 212 is arranged opposite to the first clamping component 211, and a material gap 213 is formed between the second clamping component 212 and the first clamping component 211. When clamping is not required, the material tape passes through the material gap 213 to realize feeding and winding; when clamping is required, the clamping of the material tape is realized by the first clamping component 211 and the second clamping component 212.

[0029] The driving mechanism 30 is used to drive the clamping mechanism. It is small in size and simple in structure, and can effectively eliminate the dust problem originally caused by the impact and collision between the cam groove and the cam bearing. Specifically, the driving mechanism 30 includes a transmission cam 32 and a transmission connecting rod 33.

Specifically, the first cam portion 321 is connected to the driving end of the driving component 31, and one end of the transmission connecting rod 33 is rotatably connected to the second cam portion 322. Different transmission cams 32 can be set according to actual needs. Preferably, it is set as a combination of two components for easy processing. The other end of the transmission connecting rod 33 is connected to the second clamping component 212, so that the power of the driving component 31 is transmitted to the second clamping component 212, and the second clamping component 212 is driven. Preferably, a bearing structure is provided to achieve a rotatable connection of the corresponding components. The axes of the first cam portion 321 and the second cam portion 322 are at different positions. By setting the axis distance between the first cam portion 321 and the second cam portion 322, the distance between the first clamping component 211 and the second clamping component 212 can be adjusted to adapt to different thicknesses of the material strip. The transmission cam 32 is disposed in a split form, which is not only convenient for processing, but also convenient for replacing the second cam portion 322 according to the material strips of different thicknesses.

[0030] The driving component 31 drives the first cam portion 321 to rotate, driving the second cam portion 322 to rotate around the first cam portion 321. The second cam portion 322 rotates with the first cam portion 321, so that the transmission connecting rod 33 drives the second clamping component 212 to move. After the second clamping component 212 moves, it cooperates with the first clamping component 211 to clamp or release the material belt.

[0031] The material insertion clamping device described in the utility model replaces the combination of the cam groove and the cam bearing by setting a transmission cam 32 and a transmission connecting rod 33, so as to realize the relative approaching movement or relative moving away movement of the first clamping part 211 and the second clamping part 212, thereby clamping or releasing the material belt. It can eliminate the problems of service life and dust pollution caused by the impact and collision between the cam groove and the cam bearing while effectively ensuring the clamping effect. Thereby, the product can be prevented from being contaminated by dust and the quality of the product can be guaranteed. In addition, the structure of the whole device is simple, and its volume is smaller than that when it is originally transmitted through the cam groove and the cam bearing, which is convenient for improving space utilization and reducing costs and installation difficulty.
