[0002] In the modern plastic processing industry, the drying of plastic particles is a very important pretreatment process. Plastic particles that are not fully dried are prone to produce bubbles during high-temperature melting, resulting in problems such as voids and reduced strength in the finished product.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] like Figures 1-3 As shown, a plastic particle drying device in this embodiment includes a drying machine body 1 and a vibrating conveyor belt 2. A connecting groove 201 is provided at the connection between the drying machine body 1 and the vibrating conveyor belt 2. A hot air sprayer 3 is fixedly connected to the lower end of the vibrating conveyor belt 2. An air retention component 4 is arranged in the machine body. The air retention component 4 is used to shovel up the material transported on the vibrating conveyor belt 2 to extend its air retention time.

[0030] The embodiment of the present application provides a plastic particle drying device which is matched with the air holding assembly 4 and used for prolonging the air holding time of the plastic particles conveyed by the vibrating conveying belt 2, so as to increase the contact time of the plastic particles with the hot air flow and increase the drying effect, solves the problem that the plastic particle drying device in the prior art uses the vibrating conveying belt 4 for conveying and throwing the plastic particles, when the thickness of the plastic particles conveyed by the vibrating conveying belt 4 is relatively thick, the throwing effect of the particles is greatly reduced, the air holding time of the plastic particles is relatively short, the plastic particles cannot be fully contacted with the hot air flow, and the drying effect is poor, and the general idea of the embodiment for solving the above problem is that: the air holding assembly 4 composed of the rotating shaft 401, the rotating disc 402, the air permeable groove 403 and the driving motor 404 is arranged, and is used for prolonging the air holding time of the plastic particles conveyed by the vibrating conveying belt 2, so that the plastic particles can be fully contacted with the hot air flow in the drying chamber, and the drying effect of the plastic particle drying device is better.

[0031] Figure 2 and Figure 3 As shown in the figure, a plurality of drying chambers 101 are arranged in the drying machine body 1, the temperature and humidity sensors 102, the exhaust fans 103 and the exhaust nets 104 are evenly arranged in the drying chambers 101, and the temperature and humidity sensors 102, the exhaust fans 103 and the exhaust nets 104 are arranged in a downward-upward distribution.

[0032] As an embodiment, the temperature and humidity sensors 102 can detect the temperature and humidity changes in each drying chamber 101, compare the temperature and humidity data through the front temperature and humidity sensor 102, the middle temperature and humidity sensor 102 and the rear temperature and humidity sensor 102, and monitor the drying effect of the plastic particles in the whole drying machine body 1, for example, when the temperature and humidity data detected by the front temperature and humidity sensor 102 is high and the temperature and humidity data detected by the middle temperature and humidity sensor 102 does not decrease much, it indicates that the current drying effect of the plastic particles is not ideal, for example, when the temperature and humidity data detected by the front temperature and humidity sensor 102 is high and the temperature and humidity data detected by the middle temperature and humidity sensor 102 decreases much, it indicates that the current drying effect of the plastic particles is ideal, and the rear temperature and humidity sensor 102 is used for detecting and recording the drying data of the plastic particles at the end of the drying operation.

[0033] As shown in the figure, Figures 2-4 The air holding assembly 4 has a plurality of air holding assemblies 4 and is rotationally connected to each drying chamber 101; the air holding assembly 4 is composed of the rotating shaft 401 rotationally connected to the drying chamber 101, the rotating disc 402 distributed on the periphery of the rotating shaft 401, the air permeable groove 403 arranged on the rotating disc 402 and the driving motor 404 used for driving the rotating shaft 401 to rotate.

[0034] As an implementation form, the driving motor 404 can drive the rotating disc 402 to rotate through the rotating shaft 401, so that the rotating disc 402 in the drying chamber 101 can shovel the plastic particles conveyed on the vibrating conveying belt 2, and the air-permeable groove 403 on the rotating disc 402 can prolong the hovering time of the plastic particles, so that the plastic particles can be fully contacted with the hot air flow to increase the drying effect.

[0035] The driving motor 404 can also drive the rotating disc 402 to move at a high speed, so that the rotating disc 402 can throw the shovelled plastic particles into the drying chamber 101, so that the plastic particles can be fully contacted with the hot air flow flowing through the drying chamber 101 to increase the drying effect.

[0036] As shown in Figure 2 and Figure 3 , the hot air distributor 3 is provided with a gas distribution chamber 301 and a diffusion groove 303, and the gas distribution chamber 301 and the diffusion groove 303 are provided with a gas distribution net 302 through a clamping groove, and the lower end of the hot air distributor 3 is fixedly connected with a gas supply pipeline 304.

[0037] As an implementation form, the gas supply pipeline 304 can deliver hot air into the gas distribution chamber 301, and the hot air is uniformly filled into the diffusion groove 303 through the gas distribution net 302, and then the hot air is extracted and discharged by the exhaust fan 103, so that the hot air forms a hot air flow for penetrating the plastic particles conveyed on the vibrating conveying belt 2 to perform hot air drying.

[0038] As shown in Figures 1-3 , the lower end of the hot air distributor 3 is fixedly provided with a support 305 at four corners.

[0039] As an implementation form, the support 305 can stably support the hot air distributor 3 to ensure the stable working state of the hot air distributor 3.

[0040] As shown in Figure 1 , the drying chamber 101 is fixedly provided with a control unit 5 on one side wall, and the control unit 5 is electrically connected with the driving motor 404, the temperature and humidity sensor 102 and the exhaust fan 103.

[0041] As an implementation form, the control unit 5 can control the working states of the driving motor 404, the temperature and humidity sensor 102 and the exhaust fan 103, and can also automatically control the working power of the corresponding electric appliance according to the set data. For example, when the temperature and humidity data detected by the front temperature and humidity sensor 102 is high and the temperature and humidity data detected by the middle temperature and humidity sensor 102 does not decrease much, it indicates that the drying effect of the plastic particles is not ideal, and the control unit 5 automatically controls the corresponding exhaust fan 103 to increase the working power, so as to increase the air flow rate of the hot air flow, thereby increasing the drying effect. At the same time, the control unit 5 can also automatically control the corresponding driving motor 404 to increase the working power, so that the corresponding rotating disc 402 increases the rotating speed, and the plastic particles scooped up by the rotating disc 402 can be thrown into the drying chamber 101, thereby increasing the drying effect.
