Abstract
Description
Technical Field
[0001] This utility model relates to the field of PET sheet processing technology, specifically a shearing table for PET sheet processing. Background Technology
[0002] PET sheets are thermoplastics made of polyethylene terephthalate (PET), possessing excellent physical properties and chemical stability. They feature high transparency, good mechanical strength and dimensional stability, as well as excellent chemical resistance and electrical insulation. PET sheets are widely used in packaging, electronics, food, medical, and advertising industries, favored for their environmental friendliness and recyclability. PET sheets have good processing properties, are easy to mold and process, and are suitable for various processing techniques such as thermoforming, printing, and die-cutting. PET sheets are of great importance to environmental protection and sustainable development, and are an essential material in modern packaging and industrial applications.
[0003] A shearing structure for PET sheet processing, as disclosed in announcement number CN220741300U, includes a frame with a hydraulic cylinder embedded in the top. This invention features a guide installed inside the frame, with two clamping blocks installed on one side of the frame. When the PET sheet is transported to the bottom of the cutter, the two clamping blocks clamp and limit its movement. The inner wall of the guide and the circular inner wall formed by the two clamping blocks are in close contact with the surface of the PET sheet. When the cutter cuts the PET sheet, these blocks act as a limiting support, preventing deformation and bending of the PET sheet, thus improving the yield. An electric telescopic rod allows for position adjustment of the connecting rod, which in turn adjusts the position of the contact switch on the connecting plate. This eliminates the need for workers to disassemble the switch bracket, improving the convenience of adjustment.
[0004] The aforementioned device has low shearing accuracy during use, and the debris generated during shearing is inconvenient to clean, affecting subsequent shearing accuracy. Therefore, we propose a shearing table for PET sheet processing to solve the problems mentioned above. Utility Model Content

[0009] Preferably, a collection box is provided at the lower end of the cutting port.
[0010] Preferably, the limiting device includes a limiting seat, a clamping member, and a buffer member. The limiting seat is disposed at the lower end of the movable seat. The limiting seat contains two sets of buffer members, which are symmetrically disposed at the lower inner side of the limiting seat. The lower ends of the two sets of buffer members are provided with clamping members, and the clamping members are guided and connected to the limiting seat.
[0011] Preferably, both sets of buffer components include a buffer spring and a damping rod. The upper and lower sides of the damping rod are respectively assembled and connected to the lower inner end of the limiting seat and the upper end of the clamping component. The buffer spring is disposed on the outer side of the damping rod and is elastically connected to the limiting seat and the clamping component.
[0012] Preferably, the cleaning module is provided in two sets. Each set of cleaning modules includes an air supply module, an exhaust component, a connecting pipe, and a connector. The two sets of air supply modules are symmetrically arranged on the upper end of the limiting seat. Two sets of connectors are symmetrically arranged on the front and rear sides of the air supply module. A connecting pipe is provided on the other side of each connector.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model sets limit devices symmetrically on the front and rear sides of the shearing module, and uses the clamping parts in the limit seat to clamp and limit the front and rear sides of the PET sheet. With the lifting device controlling the lifting movement of the shearing blade, the shearing effect of the PET sheet is achieved, thus solving the problem of low shearing accuracy.
[0015] (2) By setting a cleaning module at the upper end of the limiting device, during the process of cutting PET sheets, the air supply module is activated to push the slag generated by the cutting towards the middle. After the cutting blade is lifted, it is sent to the collection box through the cutting port, which plays a role in the centralized processing and collection of the slag. This solves the problem that the slag generated during the cutting process is inconvenient to clean and affects the subsequent cutting accuracy. Attached Figure Description

A shearing module 4 is provided at the lower end of the limit module 2, and a cleaning module 3 is provided in the limit module 2. By symmetrically providing limit devices 23 on both the front and rear sides of the shearing module 4, the PET sheet is pressed and limited on both sides by the clamping member 232 in the limit base 231. The lifting device 41 controls the lifting movement of the shearing blade 42, thereby achieving the shearing effect on the PET sheet and solving the problem of low shearing accuracy. By setting a cleaning module 3 at the upper end of the limiting device 23, during the shearing of the PET sheet, the air supply module 31 is activated to push the slag generated by shearing towards the center through the symmetrically arranged exhaust components 32. After the shearing blade 42 is lifted, it is sent to the collection box 7 through the shearing port, which plays a role in the centralized processing and collection of slag. This solves the problem that the slag generated during the shearing process is inconvenient to clean and affects the subsequent shearing accuracy.

The upper end of the movable seat 21 is provided with a guide block 22, and the movable seat 21 is guided and connected to the support seat 6 through the guide block 22.

The lifting device 41 is located at the lower end of the movable seat 21, and the shearing blade 42 is located at the lower end of the lifting device 41. The shearing blade 42 is located at the upper end of the shearing opening and plays the role of shearing the PET sheet.
[0025] Please see Figure 1 A collection box 7 is installed at the lower end of the shearing port to collect and process the debris.
[0026] Please see Figure 4The limiting device 23 includes a limiting seat 231, a clamping member 232, and a buffer member 233. The limiting seat 231 is located at the lower end of the moving seat 21. The buffer member 233 is provided inside the limiting seat 231. Two sets of buffer members 233 are provided and are symmetrically arranged at the lower end of the inner side of the limiting seat 231. The clamping member 232 is provided at the lower end of the two sets of buffer members 233. The clamping member 232 is guided and connected to the limiting seat 231. By symmetrically setting the limiting device 23 on the front and rear sides of the shearing module 4, the clamping member 232 in the limiting seat 231 clamps and limits the front and rear sides of the PET sheet. In conjunction with the lifting device 41, the lifting movement of the shearing blade 42 is controlled, thereby achieving the shearing effect of the PET sheet and solving the problem of low shearing accuracy.
[0027] Please see Figure 4 Both sets of buffer components 233 include a buffer spring 2331 and a damping rod 2332. The upper and lower sides of the damping rod 2332 are respectively assembled and connected to the lower inner end of the limiting seat 231 and the upper end of the clamping component 232. The buffer spring 2331 is located on the outside of the damping rod 2332 and is elastically connected to the limiting seat 231 and the clamping component 232, which plays the role of shear buffering and protecting the surface of the PET sheet.

An exhaust component 32 is provided at the lower end of the connecting pipe 33 and is connected to the exhaust component 32. The exhaust component 32 is fitted and connected to the limiting seat 231. By setting the cleaning module 3 on the upper end of the limiting device 23, during the shearing of PET sheets, the air supply module 31 is activated to push the symmetrically arranged exhaust component 32 to push the debris generated during shearing towards the center. After the shearing blade 42 is lifted, the debris is sent to the collection box 7 through the shearing port, which plays a role in centralized processing and collection of debris. This solves the problem that the debris generated during the shearing process is inconvenient to clean and affects the subsequent shearing accuracy.
