[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figures 1-4As shown, a PET plastic sheet production equipment includes: a main body 1 and a mounting frame 5. The mounting frame 5 is installed on the top rear end of the outer surface of the main body 1. Cooling water is stored in a water tank 9 and flows into a first connecting pipe 26 through a second water pipe 25. Then, it flows into several sets of second connecting pipes 27 from the first connecting pipe 26. When the formed plastic sheet falls onto the conveyor belt 4, the cooling water is injected into the rotating roller 28 through the second connecting pipes 27. The rotating roller 28 sprays the cooling water out through water holes 29, which can reduce the material temperature in time, cool it quickly, prevent deformation, and prevent overheating. A fixing frame 2 is fixedly installed at the bottom of the outer surface of the main body 1, and a water tank 9 is installed at the top of the outer surface of the mounting frame 5. The cooling water then enters a recycling tank 13 through a discharge hole 30. After that, the water pump 10 is turned on to recycle the cooling water back into the water tank 9, thereby achieving the purpose of recycling. A first water pipe 1 is fixedly installed at the front end of the outer surface of the water tank 9. 4. A water pump 10 is fixedly installed on the shaft surface of the first water pipe 14. A recycling box 13 is fixedly installed at the top of the shaft surface of the first water pipe 14. A discharge hole 30 is opened at the bottom of the middle of the outer surface of the main body 1, and the discharge hole 30 is connected to the recycling box 13. A third motor 3 is fixedly installed on one side of the front end of the outer surface of the main body 1. A rotating roller 28 is installed through the output end of the third motor 3 through the outer surface of the main body 1. Several sets of rotating rollers 28 are arranged along the internal radial direction of the main body 1. A conveyor belt 4 is sleeved on the outer surface of the rotating roller 28. Several sets of water holes 29 are opened on the outer surface of the conveyor belt 4 and the rotating roller 28. A second connecting pipe 27 is fixedly installed at the rear end of the outer surface of the rotating roller 28. A first connecting pipe 26 is installed through the top of the shaft surface of the second connecting pipe 27 through the outer surface of the main body 1. A second water pipe 25 is fixedly installed at one end of the outer surface of the first connecting pipe 26, and one end of the shaft surface of the second water pipe 25 is fixedly installed in the water tank 9.

[0022] Furthermore, a mounting base 8 is fixedly installed on the rear end of the outer surface of the main body 1. A conveying pipe 7 abuts against the top of the outer surface of the mounting base 8. The inlet 22 is located at the top of the working box 12 and is the entrance for processing in the working box 12. Then, the first motor 15 drives multiple sets of rotating rods 17 connected to it to rotate through the first rotating shaft 16. Heating rods 19 are inserted between the rotating rods 17. This allows the material to be stirred evenly by the rotation of the rotating rods 17 when it is conveyed to the working box 12. At the same time, the temperature is increased by the heating rods 19, which enhances the fluidity of the material and the processing efficiency. The surface of the heating rods 19 is covered with a protective sleeve 18, which can protect the heating element and ensure safe operation. A discharge port 20 is provided at the bottom middle part of the working box 12 to control the discharge of the processed material. The outlet 20 is equipped with a valve 21, which can be opened and closed as needed to adjust the material discharge rate. A working box 12 is fixedly installed at the rear end of the shaft surface of the conveying pipe 7. A bottom block 11 is installed at the bottom end of the outer surface of the working box 12. An inlet 22 is opened at the top end of the outer surface of the working box 12. A first motor 15 is fixedly installed at the top end of the outer surface of the working box 12. A first rotating shaft 16 is installed through the outer surface of the working box 12 at the output end of the first motor 15. Several sets of rotating rods 17 are installed on the shaft surface of the first rotating shaft 16. Heating rods 19 are inserted between the several sets of rotating rods 17. A protective sleeve 18 is sleeved on the outer surface of the heating rods 19. An outlet 20 is fixedly installed at the middle of the inside of the working box 12 at the bottom of the rotating rods 17. A valve 21 is installed on the shaft surface of the outlet 20.

[0023] Furthermore, a second motor 35 is fixedly installed at the rear end of the outer surface of the working box 12. The output end of the second motor 35 passes through the outer surface of the working box 12 and is equipped with a second rotating shaft 23. The material flowing out of the outlet 20 of the working box 12 first enters the mixing dragon 24. The second motor 35 drives the second rotating shaft 23, which in turn drives the rotation of the mixing dragon 24. Through this power configuration, it is ensured that even during the material output process, a good stirring and mixing effect is maintained. The stirred material is conveyed forward along the guide of the conveying pipe 7 and further processed by the extruder 6 located at the front end of the outer surface of the conveying pipe 7. The front end of the extruder 6 is designed with a discharge chute 34, which creates conditions for the molding of plastic sheets. This trough not only helps control the outflow of materials, but also allows for adjustment of thickness and shape when necessary. When needed, the air pump 31 is activated, causing the connecting rod 32 to move the extrusion plate 33 downward, thereby controlling the thickness of the product. The shaft surface of the second rotating shaft 23 is fixedly mounted with a stirring dragon 24, and one end of the second rotating shaft 23 and the stirring dragon 24 extends into the interior of the conveying pipe 7. The front end of the outer surface of the conveying pipe 7 is fitted with an extrusion piece 6, and the front end of the outer surface of the extrusion piece 6 is provided with a discharge trough 34. The bottom end of the outer surface of the mounting frame 5 is equipped with an air pump 31, and the output end of the air pump 31 is equipped with a connecting rod 32. The bottom end of the shaft surface of the connecting rod 32 penetrates the outer surface of the extrusion piece 6 and is equipped with an extrusion plate 33. The conveyor belt 4 is located at the bottom of the front end of the outer surface of the extrusion piece 6.

[0024] Working principle and implementation: First, the material is fed into the working box 12 through the inlet 22 at the top of the working box 12. The first motor 15 is started to drive the first rotating shaft 16 and the rotating rod 17 to rotate. At the same time, the heating rod 19 is energized to heat and stir the material, improving its fluidity and mixing uniformity. The sheath 18 covers the heating rod 19 to ensure operational safety. The valve 21 adjusts the opening of the outlet 20 to control the material feeding speed. Subsequently, the processed material enters the conveying pipe 7 through the outlet 20. The second motor 35 drives the second rotating shaft 23 to drive the stirring drum 24 to further stir and convey forward. The material is fed into the conveyor pipe 7 and then shaped through the discharge chute 34 of the extruder 6. At this time, the air pump 31 is started, and the extrusion plate 33 is pushed down through the connecting rod 32 to adjust the forming thickness of the plastic sheet. The formed plastic sheet then falls into the conveyor belt 4. The third motor 3 drives the rotating roller 28 to drive the conveyor belt 4, and the cooling system is started simultaneously: the cooling water in the water tank 9 flows through the second water pipe 25 and the first connecting pipe 26 to each of the second connecting pipes 27, and is injected into the rotating roller 28 and then evenly sprayed onto the surface of the plastic sheet through the water holes 29 to achieve rapid cooling and shaping and prevent deformation. The sprayed cooling water flows into the recycling tank 13 through the discharge hole 30 at the bottom of the main body 1, and is pumped back to the water tank 9 by the water pump 10 through the first water pipe 14 for recycling, forming a closed-loop cooling system. Finally, the cooled plastic sheet is conveyed to the next process by the conveyor belt 4, completing the entire production process from raw material processing, heating and shaping, cooling and shaping to resource recycling.
