In addition, the materials are easy to accumulate, and the contact between hot air and raw materials is not sufficient, resulting in insufficient uniformity. In order to solve the above technical problems, it is necessary to design a raw material drying institution for plastic product production. Utility Model Content

[0022] Please see Figure 1 and Figure 3 The conveyor belt 3 is movably sleeved on the surface of the inner cavity of the housing 1 by the rotating rod 2. The rotating shaft of the drive motor 4 passes through the inner cavity of the housing 1 and is fixedly connected to the rotating rod 2. An electric telescopic rod 17 is installed through the top of the housing 1. The bottom end of the electric telescopic rod 17 is fixedly connected to the air inlet pipe 10. The conveyor belt 3 is in movable contact with the inner wall of the housing 1. The rotating rod 2 on the rear side is movably connected to the inner wall of the housing 1. By setting the rotating rod 2, the bearing supports the conveyor belt 3 and fixes it in the housing 1, so that it can rotate around the fixed point.

[0023] Please see Figure 2 The surface of the treatment box 6 is movably connected to the box door by a hinge. The surface of the box door is welded with a handle. By setting the box door, the internal space of the treatment box 6 is sealed and protected, and the electric heating filter plate 14 and activated carbon filter plate 15 are supported. By setting the handle, a stable and comfortable grip is provided, ensuring that the user can accurately and forcefully operate the box door.

[0024] Please see Figure 4 The inner cavity of the treatment box 6 is welded with a support plate 18. The electric heating filter plate 14 and the activated carbon filter plate 15 are movably placed on the surface of the support plate 18. The inner cavity of the treatment box 6 is movably placed with a collection frame 19. By setting the support plate 18, a support point is provided for both the electric heating filter plate 14 and the activated carbon filter plate 15, so that they can withstand lateral pressure.

[0025] Please see Figure 1 and Figure 4 An air inlet mesh plate 20 is embedded in the top of the heating box 5, and a fan 21 is installed in the inner cavity of the fan box 8. One end of the return pipe 16 penetrates the inner wall of the heating box 5. By setting the air inlet mesh plate 20, impurities in the air are filtered, the internal components of the heating box 5 are protected from external impacts, and the fan 21 is ventilated.

[0026] Please see Figure 4 A drive rod 22 is provided through the surface of the housing 1. The surfaces of the rotating rod 2 and the drive rod 22 are movably fitted with a transmission belt 23 through a transmission disc. One end of the drive rod 22 passes through the inner cavity of the housing 1 and is rotatably connected to the inner wall of the housing 1. A flipping plate 24 is fixedly fitted on the surface of the drive rod 22 located in the inner cavity of the housing 1. The drive rod 22 is used to connect the transmission belt 23 and the flipping plate 24 and transmit power to the flipping plate 24.

[0027] Please see Figure 2 A bearing is provided at the connection between the drive rod 22 and the inner wall of the housing 1. The outer ring of the bearing is fixedly connected to the inner wall of the housing 1, and the inner ring of the bearing is sleeved on the surface of the drive rod 22. By setting the bearing, the rotating body drive rod 22 is supported, the friction and wear of the housing 1 during the movement are reduced, and the smooth rotation of the drive rod 22 is ensured.

[0028] In use, the drive motor 4 can be started to drive the rotating rod 2 to rotate. The rotating rod 2 drives the transmission belt 23 and the conveyor belt 3 on its surface to rotate synchronously. The transmission belt 23 transmits the power generated by the rotation of the rotating rod 2 to the drive rod 22. The rotation of the conveyor belt 3 transfers the material from one position to another, enabling continuous and efficient material transportation. The rotation of the drive rod 22 drives the flipping or tilting plate 24, which can change the flow path and speed of the material, making the raw materials looser during the drying process, which is conducive to the penetration and drying of hot air. Activating the electric telescopic rod 17 can adjust the distance between the material and the air inlet pipe 10 to improve drying efficiency. By starting the fan 21 and the heating ring 7 respectively, external air is filtered along the air inlet mesh plate 20 from the fan box 8 to the inside of the heating box 5. The heating ring 7 heats the air drawn into the heating box 5 and then passes it through the hose. The hot air is transported to the inlet pipe 10 through the exhaust pipe 9 and delivered into the housing 1 to dry the raw materials. Due to the air pressure generated by the operation of the fan 21 inside the heating box 5, the fan box 8 connected to the heating box 5 is connected to the processing box 6 through the return pipe 16. During the operation of the fan 21, the internal hot air and impurity particles are transported to the processing box 6 through the ventilation pipe 12 and the duct 13. An electric heating filter plate 14 and an activated carbon filter plate 15 are installed on the inner cavity of the processing box 6. The activated carbon filter plate 15 can effectively filter the retained dust and ensure the cleanliness of the hot air, while the electric heating filter plate 14 can effectively absorb the moisture in the hot air and further improve the drying effect. This dual filtration system ensures the quality of the hot air and improves the drying efficiency and uniformity. Then, along the return pipe 16, the discharged hot air is sent back to the heating box 5 in the drying process for reuse, realizing the recycling of hot air.

[0029] In summary, this raw material drying mechanism for plastic product manufacturing solves the problems of wasted heat energy and insufficient contact between hot air and raw materials through the cooperation of the housing 1, rotating rod 2, drive motor 4, heating box 5, processing box 6, heating ring 7, fan box 8, air duct 9, air inlet pipe 10 and adjustment mechanism 11.
