[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Combined with appendix Figs. 1-3A flattening device for polyethylene sheet production includes a support frame 1, a flattening structure 2 in the middle of the support frame 1, a first limiting structure 3 and a second limiting structure 4 on the front and rear sides of the support frame 1 respectively, and a first rotating roller 6 rotatably disposed in the middle of the support frame 1 and an upper frame 8 disposed at the top of the support frame 1. An electric cylinder 9 is connected to the top of the upper frame 8, and a lifting frame 10 is provided below the upper frame 8 at the bottom power end of the electric cylinder 9. A flattening rotating roller 11 that cooperates with the first rotating roller 6 is rotatably connected inside the lifting frame 10. That is, the electric cylinder 9 can drive the lifting frame 10 and the flattening rotating roller 11 to lift and lower, thereby adjusting and flattening polyethylene sheets of different thicknesses. At the same time, this equipment does not have a drive device. It is generally used in conjunction with front and rear conveying equipment. That is, this equipment is generally installed at the rear end of the production equipment, and the production equipment provides the conveying power for the polyethylene sheets. At the same time, a motor that drives the first rotating roller 6 to rotate can also be set on the outside of the support frame 1 for driving operation.

[0021] The lifting frame 10 has limiting sleeves 12 that penetrate the upper frame 8 at both ends of its top. The upper frame 8 has a limiting sleeve 13 that fits onto the limiting sleeves 12. The limiting sleeves 12 and the limiting sleeve 13 ensure the stable lifting operation of the lifting frame 10. A laser rangefinder 14 is connected to the bottom of one side of the lifting frame 10. The laser rangefinder 14 can digitally display the lifting height of the lifting frame 10. The specific installation requires on-site debugging to ensure the accuracy of the laser rangefinder 14.

[0022] Both the first limiting structure 3 and the second limiting structure 4 include a guide rail frame 15 disposed below the support frame 1. The top of the guide rail frame 15 is provided with a limiting groove 16. The limiting groove 16 is symmetrically provided with sliders 17 that slide synchronously inward or outward. The limiting groove 16 is rotatably provided with an adjusting screw 18 that is threadedly connected to the slider 17. The top of the slider 17 is fixedly provided with a clamping plate 19. The limiting groove 16 is provided with a support bearing 20 that supports the adjusting screw 18. The adjusting screw 18 is located on both sides of the support bearing 20 with opposite thread directions. One end of the guide rail frame 15 is connected to a motor 23 that drives the adjusting screw 18. The motor 23 drives the adjusting screw 18 to rotate. The threaded arrangement ensures that the slider 17 slides synchronously inward or outward, thereby allowing the clamping plate 19 to slide synchronously inward or outward, thus enabling clamping and positioning operations for polyethylene plates of different widths.

[0023] The first limiting structure 3 and the second limiting structure 4 include a limiting plate frame 21 set on the top of the support frame 1. The bottom of the limiting plate frame 21 is provided with a limiting rod 22 that penetrates the clamping plate 19. By setting the limiting plate frame 21 and the limiting rod 22, the stable lateral movement of the clamping plate 19 can be ensured.

[0024] The support frame 1 has multiple second rotating rollers 5 rotatably mounted at both ends. The support frame 1 has auxiliary plates 7 on both sides of the first rotating roller 6. The multiple second rotating rollers 5 and the auxiliary plates 7 can ensure the stable transverse conveying of polyethylene sheets.
