Description
Technical Field
[0001] The utility model relates to the field of screening equipment, and more specifically, to a raw material screening equipment for plastic product production. Background Art
[0002] The raw materials used in plastic product production usually include various plastic resins and additives, etc., which have excellent high temperature resistance and chemical stability, and are commonly used in the manufacture of high-end products such as aerospace and medical devices. In plastic product production, common raw material screening equipment can be vibrating screens, gyratory vibrating screens or air flow screens, etc. These devices are used to screen and classify impurities, dust or plastic particles of different particle sizes in the raw materials to ensure the raw material quality and production efficiency during the production process.
[0003] However, most of the existing raw material screening equipment for plastic product production has the following problems:
[0004] First, for the existing raw material screening equipment for plastic product production, when filtering the raw materials, it often only processes the raw materials through one screening. The holes in the screening mesh are mostly in a fixed state. Since there are raw materials of different sizes, the smaller raw materials are easily filtered and mixed with dust and impurities, which is inconvenient for screening and classifying the raw materials.
[0005] Second, for the existing raw material screening equipment for plastic product production, when screening, the screened dust and impurities accumulate in the equipment. If not cleaned, it is easy to cause the previously accumulated dust to float in the air and adhere to the surface of the raw materials during filtration, affecting the filtration quality. And when cleaning later, it is more troublesome, and there are some residues in parts such as corners, which is inconvenient for centralized collection and cleaning of the dust and impurities screened by the equipment.
[0006] Therefore, we make improvements on this and propose a raw material screening equipment for plastic product production. Content of the Utility Model

[0037] Embodiment 2:
[0038] The solution in Embodiment 1 will be further introduced below in combination with the specific working mode. See the following description for details:
[0039] As Figure 2 shown, as a preferred embodiment, on the basis of the above method, further, the output shaft of the motor 3 is fixedly connected to the central part on one side of the first gear 4, and the center line of the first gear 4 and the center line of the second gear 5 are on the same horizontal line, which can ensure that when the first gear 4 rotates, it can drive the second gear 5 to rotate smoothly.

[0044] Specifically, when the raw material screening equipment for plastic product production is in use: Combining Figure 1-8, when screening the raw materials, the device housing 1 can be supported and placed in the use position through the bracket 18. Then, the raw materials can be added into the device housing 1. When the motor 3 is started to drive the first gear 4 to rotate, the first gear 4 can drive the connecting shaft 6 to rotate through the second gear 5. The protective cover 2 can protect the rotating first gear 4 to avoid potential safety hazards. The connecting shaft 6 drives the first push block 11 to rotate through the connecting frame 10. The inclined surface of the first push block 11 can push the second push block 12 on the filter box 9. Through the fitting of the inclined surface, the filter box 9 can be pushed downward. When the filter box 9 moves, it can move smoothly under the support of the slider 8. The slider 8 can squeeze the first spring 7.
