[0038] Specifically, a plurality of support blocks 8 are evenly fixed on the outer edges of the support plate 3, which play a role in enhancing the overall stability. The top of each support block 8 is firmly connected with an L-shaped block 11, and the telescopic rod 10 is designed to be telescopic in the vertical direction, thereby adjusting the position of the moving plate 7 connected thereto. The output end of the telescopic rod 10 penetrates the top of the support block 8 and is fixedly connected with the moving plate 7, so that the moving plate 7 can move in the vertical direction by the telescopic rod 10 to adapt to different working requirements.

[0039] Please refer to the accompanying drawings Figure 1 - the accompanying drawings Figure 2 The adjusting mechanism 2 comprises a telescopic rod 201, the outer side of which is fixedly connected to the inner top end of the U-shaped frame 1, and the output end of the telescopic rod 201 is fixedly connected with an L-shaped plate 203, the inner top end of the right L-shaped plate 203 is fixedly connected with a servo motor 204, the output end of the servo motor 204 penetrates the corresponding L-shaped plate 203 and is fixedly connected with an upper pressing roller 202, the inner bottom end of the right L-shaped plate 203 is fixedly connected with a servo motor 205, the output end of the servo motor 205 penetrates the corresponding L-shaped plate 203 and is fixedly connected with a lower pressing roller 207, and the outer side of the L-shaped plate 203 is slidingly connected to the inner top end of the U-shaped frame 1.

First, one end of the shearing line is placed into the inner bottom end of the support block 8, then the telescopic rod two 10 fixedly connected with the L-shaped block one 11 is matched to press the moving plate 7 downward, so that the T-shaped sliding block 9 stably slides downward along the left and right ends of the inside of the support block 8, and finally the outer wall of the non-slip pad 6 is in contact with the outer wall of the shearing line to stabilize it. At this time, the L-shaped block two 12 fixedly connected with the U-shaped plate 17 is driven by the motor 13 fixedly connected with the L-shaped block two 12 to drive the threaded rod 16, thereby moving the moving strip 14, and at the same time, the cutting knife 15 shears the shearing line, thereby meeting the requirements of high-speed shearing line, and the clamping precision is high, avoiding the offset or deformation of the rolled piece during shearing, improving the shearing efficiency. Then, the L-shaped plate two 206 is installed at the inner bottom end of the U-shaped frame 1, and the lower pressing roller 207 is driven by the servo motor two 205. At this time, when the clamping force needs to be adjusted, the distance between the upper pressing roller 202 and the lower pressing roller 207 is adjusted to be moderate by the L-shaped plate one 203 fixedly connected with the telescopic rod one 201, and then the servo motor one 204 is started to complete the control of the clamping force. Therefore, the pinch roll can be automatically adjusted according to the characteristics and speed of different materials to ensure that the clamping force is moderate, which can stably clamp the material without excessive damage or deformation of the material.
