[0049] A lifting platform (not shown) is arranged inside the workbench 1, and the lifting platform can be driven by a motor in cooperation with a lead screw, or by a hydraulic cylinder or the like.

[0050] The cutting machine is arranged on a lifting platform and is located inside the workbench 1. The lifting platform drives the cutting machine to rise and fall. When the cutting machine rises, the cutting blade 51 of the cutting machine extends upward from the rectangular through hole 11 of the workbench 1 to cut off the plastic strip 10 pressed by the pressing mechanism 4.

[0051] The distance between the limiting baffle 32 on the discharging bracket 3 and the cutting blade 51 of the cutting machine is the length of the plastic strip 10 that needs to be cut.

[0052] The clamping mechanism 4, the cutting machine and the lifting platform are electrically connected to the controller respectively, and the controller controls each mechanism to perform corresponding preset actions according to a preset program.

[0053] In this embodiment, the operator places the plastic strip on the feeding bracket, and then the plastic strip passes through the workbench and continues to be conveyed to the left along the discharge chute of the discharge bracket. When the plastic strip abuts against the limit baffle in the discharge chute, the operator activates the control button of the controller, and the pressing mechanism is activated to press and fix the plastic strip on the workbench. Then the lifting platform drives the cutting machine to rise, and the cutting blade of the cutting machine cuts the pressed plastic strip. After the cut plastic strip is taken away, the remaining plastic strip is conveyed to the left again for the next cutting.

[0054] The plastic strip is positioned by the limiting baffle, and the plastic strip is pressed and fixed during cutting, so that the plastic strip can be cut quickly and efficiently, and the cutting length of the plastic strip is accurate.
