Description

Technical Field

[0001] The utility model relates to the technical field of hole opening, in particular to a PET material hole opening device. Background Art

[0002] PET stands for polyethylene terephthalate (PET) in Chinese, primarily including polyethylene terephthalate (PET) and polybutylene terephthalate (PBT). It is a condensation polymer of terephthalic acid and ethylene glycol. Together with PBT, it is collectively referred to as a thermoplastic polyester, or saturated polyester. PET processing requires the use of a hole-forming device.

[0003] Chinese patent number CN202222738148.8 discloses a hole-punching device for processing PET protective film, which belongs to the field of PET protective film processing technology. The hole-punching device for processing PET protective film includes a hole-punching plate and a fixing component. When the PET protective film is punched, the PET protective film can be placed vertically on the upper end of the hole-punching plate first, and then the PET protective film is fixed by the fixing component to avoid displacement of the PET protective film during the hole-punching period, thereby affecting the hole-punching. After the hole-punching is completed, the PET protective film can be lifted, so that the fixing component is reversed, and the PET protective film can be detached from the device. After the hole-punching is completed, the waste above the hole-punching plate can be dropped into the collection box below through the collection hole, so that the waste can be centrally processed.

[0004] During the use of the existing technology, the material processing speed is relatively slow. During the punching process, due to the soft texture of the material, it will be twisted and deformed, resulting in deformation of the punching position. Summary of the Invention

The mounting frame 20 is mounted on both sides of the middle of the workbench 1, the slide bar 24 is mounted inside the mounting frame 20, and the slider 22 is slidably mounted on the upper side of the slide bar 24. The second spring 21 is mounted above the slide bar 24 and is located on one side of the slider 22. During use, the tension adjusting wheel 9 is adjusted by the second spring 21. When the pulling force is large, the second spring 21 will contract, driving the slider 22 and the tension guide wheel 2 to move outward.

[0028] The working principle and usage process of the present invention are as follows: when performing hole drilling processing on PET material, the material is placed and fixed on the upper side of the discharge shaft 11, and after the material passes through the tension adjustment wheel 9 and the guide wheel, one end will be fixed on the upper side of the winding mechanism 12. During processing, the telescopic rod 5 is turned on by the switch, and the telescopic rod 5 will drive the pressure plate 6 to move downward. When the pressure plate 6 moves downward, the pressing mechanism 3 will first be used to fix the material. After the fixation is completed, the pressure plate 6 will drive the punch rod 18 to punch the material, and the waste generated by the punching is introduced into the waste trough 19. After the processing is completed, the telescopic rod 5 will drive the pressure plate 6 to move upward, and the winding mechanism 12 will be turned on to wind the material. The unprocessed material will be moved to the upper side of the workbench 1 for further processing. In the process of discharging and winding, the tension of the material is adjusted by the tension adjustment mechanism 10 to drive the tension adjustment wheel 9.
