[0026] A cylinder 5 is fixedly installed on the bottom surface of the moving block 4, and a fixing ring 20 is fixedly installed on the outer surface of the cylinder 5. The upper surface of the fixing ring 20 is fixedly connected to the bottom surface of the moving block 4. The installation of the fixing ring 20 stabilizes the cylinder 5, thereby minimizing the shaking of the cylinder 5 during operation, thereby ensuring the working stability of the cylinder 5.

[0027] A rotating motor 6 is fixedly installed at the telescopic end of the cylinder 5, a cutting knife 7 is fixedly installed at the output end of the power of the rotating motor 6, a hydraulic rod 16 is fixedly installed on the inner wall of the frame 1, a moving seat 17 is fixedly installed at the telescopic end of the hydraulic rod 16, and a placement seat 18 is fixedly installed on the inner bottom wall of the frame 1. The power provided by the hydraulic rod 16 drives the moving seat 17 to move, so that the device can place PMMA tubes of different lengths, thereby increasing the practicability of the device.

[0028] An infrared transmitter 8 is fixedly installed on the bottom surface of the moving block 4. The infrared transmitter 8 is a remote control device. It emits light outward within a certain range through an infrared transmitting tube, thereby achieving the function of controlling the signal. Two groups of electric push rods 21 are fixedly installed on the inner wall of the frame 1. A clamping sleeve 22 is fixedly installed at the telescopic end of each electric push rod 21.

When the worker cuts the PMMA tube, the worker first opens the hydraulic rod 16 according to the length of the PMMA tube, so that the hydraulic rod 16 drives the moving seat 17 to move, thereby placing the PMMA tube on the moving seat 17 and the placing seat 18, and at the same time makes the left end of the PMMA tube contact with the inner wall of the frame 1, and then the worker opens the electric push rod 21, and uses the power provided by the electric push rod 21 to drive the clamping sleeve 22 to move closer to the side that is close to each other, so that the clamping sleeve 22 clamps and fixes the PMMA tube, and then the worker opens the electric push rod 21. Open the automatic telescopic rod 9, and use the power provided by the automatic telescopic rod 9 to drive the connecting block 10 and the infrared receiver 11 to move to the right, so that the distance from the infrared receiver 11 to the left inner wall of the frame 1 is the length of the PMMA tube that needs to be cut. Then the worker turns on the rotating motor 2, and uses the power provided by the rotating motor 2 to drive the ball screw 3 to rotate, so that the ball screw 3 drives the moving block 4 to move, so that the moving block 4 drives the infrared transmitter 8 to move, and then the infrared transmitter 8 stops moving after identifying the infrared receiver 11, and the positioning of the cutting device is completed at the same time.
