[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, a PET bottle flake dehydration device includes: a base frame 1, a mounting base 2 is slidably provided on the base frame 1, and a first telescopic rod 3 is provided on one side of the mounting base 2 to drive it to slide along the base frame 1.

[0024] Mounting base 2 is provided with a mounting platform 4, which is mounted on a rotatable rotating base 5. A recessed connecting groove 6 is defined along the circumference of the rotating base 5. A plurality of drainage holes 7 are defined between the connecting groove 6 and the rotating base 5. These drainage holes 7 are evenly distributed along the circumference of mounting platform 4 and extend downward through mounting base 2. The bottom ends of the drainage holes 7 are interconnected to form a single drain outlet.

[0025] like Figure 2 and Figure 3 As shown, the top surface of the rotating circular base 5 is provided with a plurality of insertion grooves 8, and a spin drying drum 9 is disposed above it. The bottom of the spin drying drum 9 is provided with a plurality of insertion protrusions 10 that match the insertion grooves 8, and the top outer circumference is provided with a circle of protruding teeth 11. There are four insertion protrusions 10, which are evenly distributed along the circumference of the spin drying drum 9.

[0026] Above the mounting platform 4 is an outer cover 12. This cylindrical cover 12 is open at the bottom and fits into the connecting slot 6. Connecting plates 13 are located on either side. These connecting plates 13 are connected to the base frame 1 via a second telescopic rod 14, enabling the system to be raised or lowered. This second telescopic rod 14 drives the outer cover 12 and the upper structure up and down.

[0027] like Figure 4As shown, the outer drum cover 12 is internally provided with a connecting sleeve 15 and an extrusion block 16. The connecting sleeve 15 is rotatably connected to the top of the outer drum cover 12. The bottom is a cylindrical structure that adapts to the spin drying drum 9. The inner wall of the bottom is provided with concave teeth 17 that can mesh with the convex teeth 11. When the outer drum cover 12 is lowered, the connecting sleeve 15 can be placed on the top of the spin drying drum 9, so that the concave teeth 17 mesh with the convex teeth 11, achieving a transmission connection. Preferably, a limiting collar 24 is provided below the convex teeth 11 to limit the position of the connecting sleeve 15 and the spin drying drum 9.

[0028] At the same time, if Figure 4 and Figure 5 As shown, a cylindrical connecting portion 18 is provided at the center of the top of the connecting sleeve 15. This cylindrical connecting portion 18 extends from an opening in the top of the outer tub housing 12 to the top of the outer tub housing 12, and is topped with a circle of gear teeth 19. A rotatable gear 20 is provided above the outer tub housing 12. Gear 20 meshes with gear teeth 19 and is driven by a drive motor 21 located above the outer tub housing 12. Drive motor 21, via gear 20, cylindrical connecting portion 18, and connecting sleeve 15, drives the spin drum 9 to rotate and perform the spin operation.

[0029] A support box 22 is provided above the outer cylinder cover 12. The support box 22 covers the outside of the cylinder connection part 18 and the gear 20 to provide isolation and protection. A lifting cylinder 23 is provided on the top of the support box 22. The piston rod of the lifting cylinder 23 extends downward from the center of the cylinder connection part 18 to the inside of the outer cylinder cover 12, and is connected to the extrusion block 16, which can drive the extrusion block 16 to rise and fall in the spin-drying drum 9. The connecting sleeve 15 has a hole inside the cylinder connection part 18, and the piston rod extends downward from this hole to prevent rotation from interfering with the lifting cylinder 23 and the extrusion block 16. The extrusion block 16 is compatible with the spin-drying drum 9 and can squeeze the bottle flakes in the drum together to improve the drying effect.

[0030] The driving motor 21 is also arranged outside the supporting box 22 .

[0031] Working process: PET bottle flakes to be dried are placed into the drying drum 9, which is then placed on the rotating round base 5. The first telescopic rod 3 is activated to move the drying drum 9 and its various components to below the outer drum cover 12. The second telescopic rod 14 is then activated to lower the outer drum cover 12 and its various components, so that the bottom of the outer drum cover 12 mates with the connecting groove 6 and the connecting sleeve 15 mates with the top of the drying drum 9. The lifting cylinder 23 is then activated to drive the squeezing block 16 to press the bottle flakes together in the drying drum 9. The drive motor 21 is then activated to rotate the drying drum 9 to perform the drying operation. After drying is completed, the outer drum cover 12 and its various components rise, and the drying drum 9 and its various components move forward. The drying drum 9 can then be removed for material replacement.

[0032] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
