Description

Technical Field

[0001] This utility model relates to the field of sheet metal pressing technology, and in particular to a pressing device for processing multi-layer PETG sheets. Background Technology

[0002] PETG, short for polyethylene terephthalate-1,4-cyclohexanediethanol, is a product of transesterification polymerization of terephthalic acid (PTA), ethylene glycol (EG), and 1,4-cyclohexanediethanol (CHDM). Compared to PET, it contains the 1,4-cyclohexanediethanol comonomer, and compared to PCT, it contains the ethylene glycol comonomer. Therefore, PETG's properties differ significantly from those of PET and PCT. PETG sheets exhibit outstanding toughness and high impact strength, 3 to 10 times that of modified polyacrylates. It also boasts a wide processing range, high mechanical strength, and excellent flexibility. Compared to PVC, it offers higher transparency, better gloss, easier printing, and environmental advantages. PETG sheets are readily used to produce products with complex shapes and high elongation ratios. Furthermore, unlike PC sheets and impact-modified acrylic, PETG sheets do not require pre-drying before thermoforming. Compared with PC sheets or acrylic sheets, it has a shorter molding cycle, lower temperature, and higher yield. It has extremely high toughness, weather resistance, chemical resistance, and thermoforming performance. It is easy to process and is environmentally friendly and economical.

[0003] Existing multi-layer PETG sheet processing and pressing equipment has shortcomings. After pressing, the sheets must be manually removed, a process that poses potential dangers, such as the possibility of workers being scratched by the edges of the sheets. Moreover, manual operation is cumbersome and time-consuming, severely reducing work efficiency and hindering the efficient and safe processing of PETG sheets. Utility Model Content

After the PETG sheet is compressed, the pressure plate rises, the spring rebounds, and the sliding block drives the spring-loaded plate on the connecting plate to automatically eject the PETG sheet. This reduces manual intervention, lowers labor intensity, and saves human resources.

[0015] This invention uses an air pump to start a drive motor that drives the main gear, which meshes with two driven gears, thereby rotating the threaded rod inside the compression chamber. This, in turn, drives the air pump on the lifting plate to rise and fall. Then, the two air pumps are started, which drive the pressure plate to compress the PETG sheet. The simultaneous operation of the two air pumps allows the pressure plate to apply more uniform pressure from different positions when compressing the PETG sheet. Attached Figure Description

[0028] There are two connecting plates 107. The two connecting plates 107 are evenly distributed on the surface with the bottom center of the compression plate 108 symmetrically. The surface of the connecting column 109 penetrates the worktable 101. The spring plate 110 is located inside the pressure groove 111.

[0029] The lifting mechanism 2 includes a support rod 201, a compression box 202 fixedly connected to the top of the support rod 201, a drive motor 203 fixedly connected to the top of the compression box 202, a main gear 204 fixedly connected to the output end of the drive motor 203, a threaded rod 205 threadedly connected to the inner wall of the compression box 202, a trailing gear 206 fixedly connected to the surface of the threaded rod 205, a lifting plate 207 threadedly connected to the surface of the threaded rod 205, an air pump 208 fixedly connected to the top of the lifting plate 207, and a pressure plate 209 fixedly connected to the telescopic end of the air pump 208.
