[0002] Pipes are materials used to make pipe fittings. Different pipe fittings require different pipe materials, and the quality of the pipes directly determines the quality of the fittings. Plastic pipes, as an important component of chemical building materials, are widely accepted by users for their superior performance, hygiene, environmental protection, and low energy consumption. They mainly include PVC drainage pipes, PVC water pipes, aluminum-plastic composite pipes, polyethylene water pipes, and polypropylene (PPR) hot water pipes. During the processing of plastic pipes, it is often necessary to punch holes in the plastic pipes, and many of the holes need to be punched continuously and evenly, so that the holes are continuously and evenly arranged.

[0003] When punching holes in existing plastic pipes, it is necessary to first measure and locate the locations of the holes on the pipe and mark them. Then, a professional punching tool is used to punch holes in sequence according to the marks made after positioning. Although there are professional punching tools, measuring the distance between two adjacent holes and performing the punching operation are time-consuming and labor-intensive, with high labor intensity and low efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide an online continuous punching device for PE pipes. The encoder and the roller cooperate to measure the length of the pipe fed during the pipe transportation process. After reaching the set length, the servo motor is controlled to work. When the servo motor is working, the lifting and sliding assembly drives the punching assembly to contact the pipe, completing the automatic punching operation of the pipe, avoiding manual measurement and positioning of the hole position, reducing labor and improving work efficiency.

The power output end of the servo motor 8 is provided with a lifting and sliding assembly on the outer side of the connecting plate 3. Preferably, the lifting and sliding assembly drives the punching assembly to complete the up and down and left and right movements when working. When the punching assembly moves downward, it can contact the pipe 19 and complete the punching operation of the pipe 19. When the punching assembly moves to the left, it can punch the pipe 19 during the feeding process of the pipe 19. When the punching assembly moves upward and right, it realizes the reset function after the punching is completed. The lifting and sliding assembly includes a first runner 9 arranged at the power output end of the servo motor 8, and a second runner 10 is rotatably arranged on the connecting plate 3 and located on the upper side of the first runner 9. A synchronous belt 11 is provided between the first runner 9 and the second runner 10 to drive the second runner 10 to rotate. An eccentric shaft 12 is fixedly eccentrically arranged on the outer sides of the first runner 9 and the second runner 10.

Preferably, a corresponding parameter value is set on the touch screen operating system 23 according to the spacing between two adjacent holes to be punched. When working, the roller 22 is controlled The encoder 21 works. When the encoder 21 works to the set parameter value, the encoder transmits a control signal to the control unit. The control unit processes the signal and sends a signal to the servo motor 8, so that the servo motor 8 works and stops within the set time. When the servo motor 8 works, it drives the lifting and sliding assembly to move. When the lifting and sliding assembly moves, it drives the drill bit 16 to contact the pipe 19 to complete the punching function, avoiding the existing manual steps of measuring the spacing between the holes and positioning them on the pipe. The setting of the punching assembly can automatically punch holes in the pipe, avoiding the time-consuming and labor-intensive manual punching, reducing labor and improving work efficiency.

No further details will be given here.

[0025] Working principle:

[0026] Before working, first set the corresponding numerical range on the touch screen operating system 23 according to the size of the hole spacing between two adjacent holes, and then adjust the distance between the drill bit 16 and the pipe 19 through the handle 7 according to the diameter of the pipe 19 or the depth of the punching; during work, the pipe 19 is driven to move at a constant speed on the channel 18 by an external tractor. When the pipe 19 moves at a constant speed, the roller 22 cooperating with the pipe 19 rotates and drives the encoder 21 to rotate. When the encoder 21 rotates, the distance calculation can be completed. When the length calculated by the encoder 21 reaches the set spacing, the encoder 21 and the touch screen operating system 23 transmit the signal to the control unit. After the control unit processes the signal, it transmits it to the servo motor 8. The servo motor 8 operates intermittently. When the servo motor 8 works, it drives the lifting and sliding assembly to work. When the lifting and sliding assembly works, it drives the punching assembly to contact the pipe 19 to complete the punching action of the pipe 19.
