[0032] When in use, the upper surfaces of the four vertical extension plates 101 are flush with the upper surface of the workbench 1, and the cutting knife is not drawn; in daily production, the cutting of the electronic protective film needs to be carried out in both length and width directions, and because the raw material is in a curled state, when cutting, in addition to ensuring that the electronic film is pressed to keep it horizontal to reduce cutting errors, it is also necessary to consider not affecting the stroke of the cutting knife; the horizontal extension plates 1202 of the two adjusting members 12 are at different levels; before loading, start the cylinder 14, and under the action of the plug column 1401 and the limit block 1402, the adjusting member 12 moves upward with the slot 1203 as the active point, because the dovetail block 303 of the clamping assembly 3 and the dovetail groove 1201 of the adjusting member 12 Cooperating with each other, the adjusting member 12 moves upward to drive the clamping assembly 3 to rotate around the limiting shaft 2, so that the ball 305 is separated from the upper surface of the workbench 1. After the loading is completed, the cylinder 14 is controlled to make the limiting block 1402 press down to drive the horizontal extension plate 1202 of the adjusting member 12 to move downward until the ball 305 is in contact with the electronic film again. Under the action of several clamping assemblies 3, the electronic film is guaranteed to be in a horizontal state during cutting and processing, thereby reducing processing errors. Since the stroke of the cylinder 14 can be adjusted, the clamping assembly 3 is suitable for electronic films of different thicknesses. When in use, the distance between two adjacent clamping assemblies 3 can be adjusted by rotating the threaded section 3011 to meet the processing requirements of electronic films with different cutting widths.

[0035] When in use, the rolled electronic film raw material is wound on the conveying roller 11; the electronic film needs to be placed between the feeding roller 15 and the rubber roller 16. If a spring is used to ensure the tightness between the rubber roller 16 and the feeding roller 15, the rubber roller 16 needs to be pulled up during installation and then the electronic film is passed through the gap between the feeding roller 15 and the rubber roller 16. This creates two problems. First, frequently pulling the spring up and down will reduce the service life of the spring, which will lead to a decrease in the connection stability between the feeding roller 15 and the rubber roller 16, resulting in a malfunction. Second, the installation process is cumbersome and it is difficult for one person to operate. When the utility model is in use, Press the clamping block 1802 to disengage it from the limiting hole 602, thereby invalidating the connection between the fixing seat 2 6 and the clamping piece 18, rotate the rubber roller 16 with the connecting shaft between the movable block 9 and the fixing seat 1 8 as the center, then install the electronic film, and finally reinsert the clamping piece 18 into the deep groove 601.
