[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The auger shaft drives the bottom plastic granules upward and they enter the second receiving space through the upper opening for heating and dehumidification, thereby driving the raw material to circulate and fully dehumidify the raw material.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] Specific implementation method one: Combining Figure 1-6 As shown, a wheel cover production raw material drying device includes: a barrel body 1, the barrel body 1 is provided with a first receiving space 2, a second receiving space 3 and a heating layer 4 from the inside to the outside, the first receiving space 2 is provided with an opening 201 communicating with the second receiving space 3 at the top and bottom respectively, and a lifting component 5 and a discharge port 202 are provided at the bottom of the first receiving space 2 respectively, the second receiving space 3 is provided with a feed port 301 communicating with the outside at the top, the barrel body 1 is provided with an auger shaft 101 at the center, and an electric motor is installed on the top of the auger shaft 101;

[0028] When in use, the lifting component 5 moves upward to the bottom of the auger shaft 101, exceeding the height of the discharge port 202. The plastic granules fall into the bottom area of ​​the second receiving space 3 after passing through the feed port 301, and enter the first receiving space 2 through the lower opening 201. Driven by the auger shaft 101, the incoming plastic granules are continuously spiraled upward, and after reaching the upper opening 201, the raw material returns to the second receiving space 3, realizing a cyclical movement. The amount of raw material added should not exceed half the height of the second receiving space 3, as too much will easily reduce the efficiency of the cyclic movement. During the cyclic movement, the electric heating tube in the heating layer 4 works to heat the second receiving space 3, thereby evaporating the moisture adhering to the surface of the plastic granules, achieving a dehumidification effect, and ensuring the processing quality during subsequent melting production. After dehumidification is completed, the lifting component 5 moves downward, opening the lower discharge port 202, allowing the plastic granules to be discharged smoothly. At this time, in order to avoid residue on the auger shaft 101, the auger shaft 101 can be rotated in reverse.

[0029] Preferred embodiments, in combination Figure 3 and Figure 5 As shown, the top of the second accommodating space 3 is provided with an exhaust port 203 that communicates with the outside. Multiple exhaust ports are evenly arranged along the circumference, which can discharge the moisture generated by heating to the outside of the barrel 1.

[0030] Preferred embodiments, in combination Figure 2-6As shown, the top area of ​​the barrel 1 is provided with a middle space 102, and the bottom of the middle space 102 is provided with a number of small holes 103 that communicate with the exhaust port 203. The middle space 102 is provided with an exhaust pipe, which can accelerate the discharge of internal moisture by communicating with a negative pressure device. When the exhaust pipe is directly connected to the atmosphere, a protective net can be installed in the middle space 102 to prevent external insects and other debris from entering the second containment space 3 and affecting processing and production.

[0031] Preferred embodiments, in combination Figure 2 As shown, the intermediate space 102 is equipped with an activated carbon layer 104, which can adsorb and filter the exhaust airflow to reduce odor.

[0032] Preferred embodiments, in combination Figure 3 and Figure 4 As shown, multiple heat-conducting columns 302 are evenly arranged in the middle of the second accommodating space 3. The heat-conducting columns 302 are made of copper or aluminum, which have good thermal conductivity and a circular cross-section, which can avoid affecting the falling of plastic particles. The design of the heat-conducting columns 302 can effectively increase the probability of contact with plastic particles, and can play a separation role during the falling of plastic, ensuring that the plastic particles can be fully heated, thereby improving the dehumidification efficiency and effect.

[0033] Preferred embodiments, in combination Figure 2 and Figure 6 As shown, the lifting assembly 5 includes a hydraulic cylinder 501 and a platform 502; the hydraulic cylinder 501 is fixedly connected to the bottom of the barrel 1, and the push rod of the hydraulic cylinder 501 is fixedly connected to the platform 502. The diameter of the platform 502 is equal to the inner diameter of the first accommodating space 2. The platform 502 is lifted and lowered by the hydraulic cylinder 501, which can realize the opening or closing of the discharge port 202.

[0034] To address the issue of residual plastic particles on platform 502, a rectangular operating hole can be made in the bottom area of ​​the first receiving space 2. The operating hole is located below the discharge port 202. When the residual plastic cannot be discharged from the discharge port 202 by gravity, the hydraulic cylinder 501 can be activated to continue moving downwards. Once it reaches the discharge port 202, it can be manually removed.

[0035] Preferred embodiments, in combination Figure 6 As shown, a collection trough 204 is provided at the discharge port 202. The collection trough 204 collects the discharged plastic, making it convenient for loading and unloading operations.

[0036] Preferred embodiments, in combination Figure 6 As shown, the bottom plane of the collection trough 204 is inclined, which can guide the plastic to a position close to the edge of the collection trough 204, making it easier to pick up.

[0037] Preferred embodiments, in combination Figure 3 As shown, the bottom of the second receiving space 3 is provided with an annular guide slope 304, which can smoothly guide the plastic particles falling from the top of the second receiving space 3 to the lower opening 201 for discharge, reducing the residue.

[0038] The number of through-holes 201 can be adjusted as needed, such as four at the top and two at the bottom, and the height of the through-holes themselves can be appropriately increased to increase the amount of plastic that can pass through.

[0039] To improve the sealing effect at platform 502, a sealing ring can be installed on the outer circumference of platform 502. The sealing ring contacts the inner wall of the first accommodating space 2 to improve the sealing effect and prevent plastic particles from falling out of the gaps.
