When assembling the LCD backlight and liquid crystal display glass in a module factory (such as BOE, TCL, TIANMA, etc.), a kind of foam double-sided tape is needed to play a role in fixing and buffering. The foam double-sided tape is located around the display and has an irregular shape. Moreover, the material of the foam double-sided tape is relatively soft. Therefore, in terms of production technology and material matching, it is necessary to ensure that the weight of the film peeled off by hand at the release paper is within a suitable range and there are no die-cutting marks at the peeling-off place of the hand, so as to ensure the use at the client side without reverse release and delamination.

Specifically, after the position of the moving tool block 200 is adjusted by the operator, the operator can rotate the tightening screw rod 220 so that the tightening screw rod 220 can drive the wedge-shaped clamping block 230 to move up and down through the cooperation with the threaded cylinder 210, so that when the operator fixes the moving tool block 200, the wedge-shaped clamping block 230 can be inserted into the clamping groove, so that the opposite sides of the wedge-shaped clamping block 230 and the wedge-shaped clamping strip 120 can be abutted, so that the fixing effect of the moving tool block 200 can be improved by the friction force between the contact surfaces of the wedge-shaped clamping strip 120 and the wedge-shaped clamping block 230.

[0028] The use process of the present utility model is as follows: First, the operator can remove the outer sealing plate 540, then select an appropriate number of cutting blades 520 according to requirements, then sleeved the cutting blades 520 on the central screw rod 510 and the guide rod, then take out the connecting spacer block 530 and place it at the side end of the cutting blade 520. After the placement is completed, the operator can take out the outer sealing plate 540 and clamp the outer sealing plate 540 on the side wall of the blade fixing frame 500, and then by screwing the locking nut 542 on the central screw rod 510, the locking nut 542 can tightly fix the cutting blade 520 and the connecting spacer block 530 through the top block 541. After the fixing is completed, the operator can loosen the tightening screw rod 220 upward, so that the tightening screw rod 220 drives the wedge-shaped clamping block 230 to move upward, and then the operator can rotate the micrometer adjuster 300 so that the micrometer adjuster 300 can drive the moving tool block 200 to slide left and right at the front end of the moving guide rail 100 through the output end, so as to adjust the position of the blade fixing frame 500. After the adjustment is completed, the operator can screw the tightening screw rod 220 so that the tightening screw rod 220 can drive the wedge-shaped clamping block 230 to move up and down through the cooperation with the threaded cylinder 210, so that when the operator fixes the moving tool block 200, the wedge-shaped clamping block 230 can be inserted into the clamping groove, so that the opposite sides of the wedge-shaped clamping block 230 and the wedge-shaped clamping strip 120 can be abutted, so that the fixing effect of the moving tool block 200 can be improved by the friction force between the contact surfaces of the wedge-shaped clamping strip 120 and the wedge-shaped clamping block 230;

[0029] Subsequently, the moving guide rail 100 can be installed at the feeding end of the device through a bracket. Then, the foam material is unwound through the unwinding shaft of the device, and the material at the tearing end is cut by the installed cutting blade 520. Then, other bonding materials are unwound from the unwinding shaft on the device, and after being bonded by the machine rollers, they are cut. In this way, the cutting distance is reduced and the effect of the cut product can be quickly inspected, greatly improving the cutting efficiency and product quality.
