A supporting rod 4 is connected to the lower part of the end of the conveyor 1 where the heating wire 3 is provided. The supporting plate facilitates the support of the polyolefin plates. A limit baffle 5 is installed on the supporting rod 4, and the limit baffle 5 can move back and forth on the supporting rod 4; the limit baffle 5 is convenient for limiting the polyolefin plates, so as to facilitate fixed-length cutting of the polyolefin plates. A proximity switch 6 is installed on the limit baffle 5. When the polyolefin touches the limit baffle 5, the proximity switch 6 can trigger a signal. Through the signal feedback, the control system of the entire cutting device can control the driving cylinder 2 to drive the heating wire 3 to cut the polyolefin plates.

[0029] Working principle: When in use, first install the control system of the entire cutting device, connect the control of the conveyor 1, the control of the driving cylinder 2, the heating wire 3 and the proximity switch 6 to the control system; and adjust the position of the limit baffle 5 according to the length of the fixed-length cutting required, and then fix the position of the limit baffle 5. Then place the polyolefin plate to be cut on the conveyor 1. The conveyor 1 drives the polyolefin plate to move. When the polyolefin plate touches the limit baffle 5, the proximity switch 6 will be triggered. The proximity switch 6 feeds back the signal to the control system. The control system controls the conveyor 1 to stop running, and at the same time controls the driving cylinder 2 to drive the heating wire 3 to move down, so that the heating wire 3 cuts the polyolefin plate. After cutting is completed, the driving cylinder 2 will drive the heating wire 3 to reset. At the same time, the staff removes the polyolefin plate, and the conveyor 1 continues to drive the polyolefin plate to move and cut. In this way, the polyolefin plate can be cut and processed efficiently. Compared with the prior art, in this application, the polyolefin plate is conveyed by the conveyor 1. A supporting rod 4 and a limit plate 32 are provided at one end of the conveyor 1. The position of the limit plate 32 can be adjusted according to the length of the polyolefin plate to be cut.
