[0018] ③ The cut polyethylene pipe can be separated: through the establishment of the lower pipe mechanism, when the polyethylene pipe is cut, the cut polyethylene pipe section is placed on the concave corner of at least one group of the lower pipe mechanism, and the deflection hydraulic cylinder is driven to extend. Because the deflection hydraulic cylinder rotates with the lower pipe fixing frame and the deflection frame respectively, the extended deflection hydraulic cylinder will drive the deflection frame to deflect upward until the corner edge of the concave corner close to the rotating shaft side tilts downward. At this time, under the action of gravity, the cut polyethylene pipe section rolls down from the inclined corner edge of the concave corner, thereby completing the separation of the cut polyethylene pipe.

[0038] Brief description of the usage process:

[0039] When in use, the cutting hydraulic cylinder 15, the lifting hydraulic cylinder 25, and the deflection hydraulic cylinder 144 are connected to an external hydraulic control circuit, the cutting motor 16 and the rotating motor 33 are connected to a power supply with a control switch, and the negative pressure pipe 13 is connected to an external negative pressure dust collecting device, and the negative pressure dust collecting device generates a negative pressure sufficient to attract cutting droplets in the knife receiving cavity 93 through the negative pressure pipe 13 and the negative pressure port 94;

[0040] The pipeline conveyor conveys the polyethylene tube 17 between the rotating mechanism 3 and the rotary cutter 10, and the polyethylene tube 17 is supported by two groups of rollers 32 on the rotating mechanism 3. At this time, the cutting motor 16 is started to rotate, and the cutting motor 16 drives the rotary cutter 10 and the knife shaft 11 to rotate as a whole through the belt transmission. At this time, the cutting hydraulic cylinder 15 is controlled to extend, and the telescopic end of the cutting hydraulic cylinder 15 drives the mounting plate 8, the cutting motor 16, the rotary cutter 10, and the knife shaft 11 to move downward as a whole, so that the rotary cutter 10 partially protrudes from the cutter cover 9 and contacts the polyethylene tube 17. The rotating rotary cutter 10 cuts the tube wall of the polyethylene tube 17, and the droplets generated during cutting are collected by the negative pressure receiving chamber 93 and collected to the negative pressure port 94. The negative pressure pipe 13 connected to the negative pressure port 94 outputs the droplets to the negative pressure dust collection device;

[0041] At this time, the rotating motor 33 is started again to rotate, and the rotating motor 33 drives the roller 32 to rotate through the belt transmission. The rotation of the roller 32 drives the polyethylene tube 17 thereon to rotate. When the polyethylene tube 17 rotates a full circle, the rotary cutter 10 completes the circular cutting of the polyethylene tube 17, and then cuts off the polyethylene tube 17.

[0042] After the polyethylene tube 17 is cut, the cut section of the polyethylene tube 17 is placed on the concave corner 143 of at least one group of the lower tube mechanisms 14. At this time, the deflection hydraulic cylinder 144 is driven to extend. Since the deflection hydraulic cylinder is respectively rotated with the lower tube fixing frame 141 and the deflection frame 142, the extended deflection hydraulic cylinder 144 will drive the deflection frame 142 to deflect upward until the corner edge of the concave corner 143 close to the rotating shaft 145 is tilted downward. At this time, under the action of gravity, the cut section of the polyethylene tube 17 rolls down from the tilted corner edge of the concave corner 143, thereby completing the separation of the cut polyethylene tube 17.

[0043] At this time, the cutting hydraulic cylinder 15 and the deflection hydraulic cylinder 144 are reset, and the polyethylene pipe 17 is continuously transported forward by the pipeline conveyor, and the cutting operation of the next section of the polyethylene pipe 17 is completed in the same manner as above.

[0045] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
