Description

Technical Field

[0001] This utility model relates to the field of plastic particle production technology, specifically to a raw material cleaning device for plastic particle production. Background Technology

[0002] Plastic pellets, also known as plastic granules, are intermediate products in the plastics processing. They are formed by the polymerization reaction of monomers such as ethylene and propylene derived from petroleum into high molecular compounds, which are then granulated into granular semi-finished products. They are widely used in industrial production and daily life. Common plastic pellets include general-purpose plastics, engineering plastics, and specialty plastics. They can be used to manufacture various plastic bags, buckets, basins, toys, stationery, various building components, building tools, plastic doors and windows, mortar buckets, and other plastic products.

[0003] In the production of plastic pellets, to prevent oil, dust, and impurities adhering to the surface of the raw materials from affecting the quality of the plastic pellets, a cleaning device is needed to clean the raw materials. A search revealed Chinese patent CN216323770U, which discloses a plastic pellet cleaning device, comprising: a cleaning tank containing cleaning liquid; a conveyor belt positioned within the cleaning tank, with its rear end extending upwards to a height above the cleaning liquid level; and a discharge ramp, its front end connecting to the output end of the conveyor belt and its rear end extending downwards to the end of the cleaning tank, with filter holes provided on the discharge ramp. This invention, using the above structure, can feed the produced plastic pellets into the cleaning tank, then remove them from the tank via the conveyor belt, and finally discharge them via the discharge ramp. During this process, the plastic pellets can be cleaned by soaking in the cleaning liquid, and the cleaning liquid can be recovered through the filter holes, preventing the cleaning liquid from being discharged.

[0004] The existing technical solutions mentioned above have the following drawbacks: during the use of the cleaning device, it is impossible to remove static electricity from the raw materials being cleaned. Static electricity is easily generated due to friction between the raw materials. At the same time, static electricity will attract dust and other impurities in the air, increasing the cleaning load of the cleaning device. Furthermore, when static electricity accumulates to a certain level, it will discharge and injure the user. Utility Model Content

A dispersing blade 405 is fixedly connected to the surface of the crossbar 404. The dispersing blade 405 is located inside the feed hopper 2.

[0028] As a technical optimization of this utility model, by setting the dispersing component 4, the raw materials entering the feed hopper 2 can be dispersed to prevent the raw materials from sticking together and affecting the cleaning effect of the cleaning device 1.

[0029] refer to Figure 4 The surface of the horizontal tube 304 is provided with air holes 5, and a protective net 6 is fitted on the surface of the horizontal tube 304. Both sides of the protective net 6 are fixedly connected to the inner wall of the feed hopper 2.

[0030] As a technical optimization of this utility model, the air hole 5 can spray negative ion air onto the raw material inside the feed hopper 2 to neutralize the static electricity on the surface of the raw material. The protective net 6 can filter the raw material and prevent it from entering the interior of the horizontal tube 304 through the air hole 5.

[0031] refer to Figure 3 A protective shell 7 is fixedly connected to the back of the feed hopper 2. The motor 401, gear 402 and gear ring 403 are all located inside the protective shell 7. The back of the motor 401 is fixedly connected to the inner wall of the protective shell 7.

[0032] As a technical optimization of this utility model, the protective shell 7 can limit and protect the motor 401, gear 402 and gear ring 403, preventing the gear ring 403 and gear 402 from pinching the user when rotating. The bushing 8 can prevent the crossbar 404 from shaking when rotating, reducing the friction between the crossbar 404 and the feed hopper 2.

[0033] refer to Figure 5 A fixing bracket 9 is provided on the rear side of the top of the pipe 301. The bottom of the fixing bracket 9 extends into the interior of the pipe 301. Dust bags 10 are fixedly connected to both sides inside the pipe 301.

[0034] As a technical optimization of this utility model, the air inside the pipe 301 can be filtered by the cooperation of the fixing frame 9 and the dust bag 10, preventing dust and debris in the air from entering the horizontal pipe 304 and the feed hopper 2.

[0035] refer to Figure 5 The top of the fixed frame 9 is provided with a stop block 11. The rear side of the bottom of the stop block 11 is movably connected to the top of the pipe 301 through a rotating shaft. The front side of the top of the stop block 11 is provided with a bolt. The threaded end of the bolt extends to the bottom of the stop block 11 and is threadedly connected to the top of the pipe 301.

[0036] As a technical optimization of this utility model, the positions of the fixing frame 9 and the dust bag 10 can be fixed by the cooperation of the stop block 11 and the bolt, making it convenient for users to disassemble and install the fixing frame 9 and the dust bag 10.

[0037] The working principle and usage process of this utility model are as follows: During use, the user pours the raw materials into the feed hopper 2, causing the output end of the motor 401 to drive the gear 402 to rotate clockwise. The rotation of the gear 402 drives the gear ring 403, crossbar 404, and dispersing blade 405 to rotate, causing the rotating dispersing blade 405 to disperse the raw materials inside the feed hopper 2. Simultaneously, the output end of the blower 303 delivers air into the pipe 301. When the air inside the pipe 301 passes through the dust bag 10, the dust bag 10 filters the air. When the filtered air passes through the negative ion generator 302, the negative ions generated at the output end of the negative ion generator 302 react with the filtered air... The air is mixed, and the output end of the pipe 301 delivers air containing negative ions into the interior of the horizontal pipe 304. Then, the air containing negative ions is sprayed into the interior of the feed hopper 2 through the air hole 5 and the protective net 6, so that the negative ions in the air neutralize the static electricity on the surface of the raw materials. At this time, the static electricity of the raw materials inside the feed hopper 2 can be removed. Afterwards, the user rotates the bolt counterclockwise to disengage the bolt from the stop block 11, and then pulls the stop block 11 to the right to rotate the stop block 11 counterclockwise around the pivot, so that the stop block 11 disengages from the fixing frame 9. Then, the fixing frame 9 is pulled upward to disengage the fixing frame 9 and the dust bag 10 from the pipe 301. At this time, the dust and debris inside the dust bag 10 can be cleaned.

[0038] In summary, this raw material cleaning device for plastic particle production disperses the raw materials inside the feed hopper 2 using the dispersing component 4 to prevent them from sticking together. Then, the static eliminator 3 sprays the dispersed raw materials to remove static electricity, preventing dust from adhering to the surface of the raw materials due to static electricity. This solves the problem that cleaning devices cannot remove static electricity from the raw materials during use, as friction between raw materials easily generates static electricity. At the same time, static electricity will attract dust and other impurities in the air, increasing the cleaning load of the cleaning device. Furthermore, when static electricity accumulates to a certain level, it will discharge and injure the user.
