It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1

[0026] See also Figure 1-6 The utility model provides a technical solution: a dryer for PET plastic processing, comprising a drying box 1, a feed port 2 is fixedly installed on the top surface of the drying box 1, a mounting seat 3 is fixedly installed on the back of the drying box 1, a motor 4 is fixedly installed on the surface of the mounting seat 3, a fan 5 is installed on the output end of the motor 4, a heating tube 6 is fixedly installed on the inner wall of the drying box 1, a working box 7 is fixedly installed on the back of the drying box 1, a motor 8 is fixedly installed on the inner wall of the working box 7, a driving gear 9 is installed on the output end of the motor 8, and driven gears 13 are meshed on both sides of the driving gear 9, so that the driving gear 9 drives the driven gear 13 to rotate when the driving gear 9 rotates, and then the driving gear 9 and the driven gear 13 drive the driving roller 10 and the driven roller 14 to rotate.

[0027] See also Figure 2-4A driven roller 14 is fixedly installed on the surface of the driven gear 13, and a driving roller 10 is fixedly installed on the surface of the driving gear 9. The shape, size and material of the driving roller 10 and the driven roller 14 are the same, so as to prevent the material from falling from the gap between the driving roller 10 and the driven roller 14. The length of the driving roller 10 matches the drying box 1. The driving roller 10 is located directly below the feed port 2, so that the material can contact with the absorbent cotton block 11 on the surface of the driving roller 10 after entering the feed port 2, so as to facilitate the absorbent cotton block 11 to absorb moisture on the surface of the material. The surface of the driving roller 10 is fixedly installed with an absorbent cotton block 11, and the absorbent cotton blocks 11 are evenly distributed on the surfaces of the driving roller 10 and the driven roller 14. The absorbent cotton blocks 11 are made of polyester sponge, which has excellent water absorption and good air permeability, so it is convenient to absorb moisture on the surface of the material and can also clean the surface of the material. A discharge port 12 is provided on the side of the drying box 1.

[0028] Embodiment 2

[0029] See also Figure 2-6 A silicone pad 15 is fixedly installed on the surface of the discharge port 12, and a fine groove is opened on the surface of the silicone pad 15 to prevent the material from popping out directly from the discharge port 12. A fixing seat 16 is fixedly installed on the side of the drying box 1, and an electric push rod 17 is fixedly installed on the surface of the fixing seat 16. A push plate 18 is installed at the output end of the electric push rod 17 to facilitate the removal of the dried material. The silicone pad 15 is made of organic silicone, which has good temperature resistance and improves the service life of the silicone pad 15. The silicone pad 15 is fixed to the discharge port 12 by inorganic glue. The silicone pad 15 is convenient for intercepting the discharge port 12 to avoid the phenomenon that the material falls in the drying box 1 and pops out directly from the discharge port 12. The top surface of the push plate 18 is flush with the discharge port 12, which facilitates the push plate 18 to push the material to the discharge port 12.

[0030] Working principle: When in use, the motor 4 and the heating tube 6 are enabled, the motor 4 drives the fan 5 to operate, and then the material is poured in from the feed port 2. Under the action of gravity, the material poured into the feed port 2 falls into the drying box 1 until the material reaches the bottom of the drying box 1. At this time, the moisture on the surface of the material can be dried by the fan 5 and the heating tube 6. After drying for a period of time, the moisture on the surface of the material is completely dried, and the material can be taken out from the discharge port 12. When pouring the material, the motor 8 is enabled, and the motor 8 drives the driving gear 9 to rotate. Since the driving gear 9 and the driven gear 13 are meshed, the driving gear 9 drives the driven gear 13 to rotate. At the same time, the driving gear 9 drives the driving roller 10 to rotate, and the driven gear 13 drives the driven roller 14 to rotate. At this time, the material is poured in from the feed port 2, and then the material is discharged from the feed port 2. The material falls downward from the outlet 2 until the material contacts the absorbent cotton block 11. Since the absorbent cotton block 11 is a polyester sponge with elasticity and water absorption, the absorbent cotton block 11 absorbs the moisture on the surface of the material under the drive of the active roller 10 and the driven roller 14, and then the material continues to fall downward until it falls on the bottom of the drying box 1. At this time, the fan 5 and the heating tube 6 can dry the water stains remaining on the surface of the material. When the material is dried, the collection box is first placed at the discharge port 12, and then the electric push rod 17 is enabled. The electric push rod 17 drives the push plate 18 to move, and the push plate 18 pushes the material at the bottom of the drying box 1 until the material is pushed to the discharge port 12. Then the material is squeezed out from the surface of the silicone pad 15 driven by the push plate 18. At this time, the material can be discharged from the discharge port 12 and fall into the collection box.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
