[0002] The molecular structure of PET plastic is highly symmetrical and has a certain crystal orientation ability, so it has high film-forming properties and properties. At present, in the process of processing PET plastic sheets, a flattening device is needed to flatten them to make the PET plastic sheets smoother.

[0003] When using the existing leveling device for processing plastic PET sheets, a hydraulic telescopic rod is usually used to drive a pressing block to press and level the plastic PET sheets. However, in actual use, we found that when it is necessary to level the plastic PET sheets of different thicknesses, the staff cannot determine the pressure applied by the pressing block to the plastic PET sheets of different thicknesses, which can easily lead to excessive or incomplete pressing of the plastic PET sheets, thereby affecting the actual processing efficiency. Therefore, how to solve this problem is what we need to consider. Utility Model Content

[0022] Among them, it also includes a lifting mechanism, which includes two second telescopic rods 8 installed at the bottom of the first inner groove 6. The two second telescopic rods 8 are hydraulic telescopic rods. The telescopic ends of the two second telescopic rods 8 are commonly fixedly connected to a support plate 9. The support plate 9 can support the plastic PET sheet for leveling operations, and it is convenient for the staff to place and recycle it. The support plate 9 is slidably connected to the inner wall of the return-shaped connecting frame 7. The horizontal plane length and width of the pressing plate 5, the support plate 9 and the first inner groove 6 are the same. The front side of the support plate 9 is fixedly connected to a first connecting block 11. The front end of the first connecting block 11 passes through a rectangular opening 10. The front end of the first connecting block 11 is fixedly connected to a pointer 12. The scale bar 13 cooperates with the pointer 12. The staff can adjust the height of the support plate 9 according to the thickness of the plastic PET sheet, the pointer 12 and the scale bar 13, so as to achieve appropriate pressing and leveling of plastic PET sheets of different thicknesses;

[0023] It also includes a cooling mechanism, which is used to accelerate the cooling and shaping rate of the plastic PET sheet. The cooling mechanism includes a water tank 14 installed at the bottom of the first inner tank 6. The water tank 14 is filled with low-temperature circulating water. A water pump 15 is installed at the inner bottom of the first inner tank 6. The water inlet pipe of the water pump 15 passes through the right wall of the water tank 14 and extends to the inner bottom of the water tank 14. The water outlet end of the water pump 15 is connected to a hose 16.
