Description

Technical Field

[0001] The utility model relates to the technical field of PE double-ring pipe production and cutting, in particular to a PE double-ring pipe production device. Background Art

[0002] A PE double-ring pipe (also known as a PE double-wall pipe or double-wall polyethylene pipe) is a pipe made of polyethylene (PE) material, usually used for drainage, sewage disposal and other liquid transmission applications. It is designed with two concentric ring walls, and a cavity is formed between the outer wall and the inner wall. The inner wall of the PE double-ring pipe has a smooth surface to reduce fluid resistance, while the outer wall provides additional strength and pressure resistance. In order to meet the requirements of specific engineering projects, the PE double-ring pipe usually needs to be cut into specific lengths by a cutting device during production. However, most of the existing PE double-ring pipe production devices still have problems to be solved during use.

[0003] When the PE double-ring pipe is cut, high temperature is generated due to the friction between the cutting knife and the PE double-ring pipe, and the PE double-ring pipe will generate polymer decomposition gas with an unpleasant smell, which is somewhat irritating. Most of the existing PE double-ring pipe production devices in the prior art do not have a protection function. These irritating gases will be emitted into the operation workshop, which will irritate the eyes or respiratory tract of the staff, resulting in uncomfortable symptoms, damage the physical health of the staff, and affect the normal progress of production work.

[0031] Working principle: When using this device, place the PE double-ring pipe between the first protective box 4 and the second protective box 7, and place the PE double-ring pipe on two second clamping plates 9. Extend the output end of the cylinder 3. The output end of the cylinder 3 will drive the first protective box 4 to descend. The first protective box 4 will drive the first limiting rod 15 to descend. Through the limitation of the first limiting rod 15, the first protective box 4 will not shift during movement. When the first protective box 4 descends, it will drive the first fixing plate 5 to descend. The first fixing plate 5 will drive the first clamping plate 6 to descend close to the PE double-ring pipe until they come into contact. The PE double-ring pipe can be clamped and fixed by the first clamping plate 6 and the second clamping plate 9. At the same time as the first protective box 4 descends, it will also drive the sealing strip 23 to descend until the two sealing strips 23 come into contact, so that the position where the PE double-ring pipe is to be cut is in a closed environment. Start the motor 22 through the PLC control device. The output end of the motor 22 will drive the lead screw 17 to rotate. The lead screw 17 will drive the lead screw nut 18 to move. The lead screw nut 18 will drive the mounting plate 19 to move. The mounting plate 19 will move along the second limiting rod 20. The mounting plate 19 will not shift during movement. Lift the mounting plate 19. The mounting plate 19 will drive the cutting machine 10 to rise. Start the cutting machine 10 through the PLC control device. The cutting tool of the cutting machine 10 rotates and rises to cut the PE double-ring pipe. At the same time, start two fans 11. One of the fans 11 sucks the outside air into the space formed by the first protective box 4 and the second protective box 7, and the other fan 11 extracts the internal air and discharges it to the purification device through the pipeline 12. As the cutting progresses, the generated irritating gas will be extracted and treated by the purification device, and then discharged into the atmosphere after treatment, avoiding the generated irritating gas from being emitted into the operation workshop and inhaled by the staff, and avoiding affecting the health and work of the staff. After completing the cutting work, reverse the output end of the motor 22, so that the cutting machine 10 can descend, retract the output end of the cylinder 3 to make the first protective box 4 rise, and make the first clamping plate 6 rise to no longer clamp the PE double-ring pipe, and then the cut PE double-ring pipe can be taken out.
