[0001] The utility model relates to the technical field of screening equipment, and more specifically to an automatic screening and conveying mechanism for rubber particles. Background Art

[0002] As people's environmental awareness increases, there are more and more ways to recycle rubber waste. Different recycling methods have greatly alleviated the pollution of waste rubber to the environment. In order to better deal with waste rubber products, it is easier to make them into fine particles.

[0003] The shortcomings of the existing technology: However, in the process of screening rubber particles in the existing technology, some larger particles will always block the screening net, which will reduce the screening efficiency and force the staff to stop the equipment to clean the internal screening net. At the same time, after the screened particles enter the storage box, the staff need to transfer them to other places, which requires the staff to consume a lot of physical strength, resulting in increased work intensity, which will cause great harm to the staff's body for a long time. For this reason, we propose an automatic screening and conveying mechanism for rubber particles. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is provided with a cutting mechanism through a receiving mechanism, and the started cutting motor drives the driving rod to rotate at a high speed, and the multiple sets of blades on the driving rod are quickly cut, and then the rubber particles with certain uneven particle sizes are poured into the material guide box, and then pass through the clustering inclined slope of the material guide box through the large screen and fall into the material passage pipe, and then are cut into smaller rubber particles by the high-speed rotating blade, and fall into the storage tank through the small screening net that rotates synchronously at the bottom, and the particles that do not pass through bounce up on the high-speed rotating small screening net and are cut by the blade again, and finally enter the storage tank through the small screening net. The setting of the cutting mechanism greatly reduces the probability of large particles blocking the screening net, and reduces the size of large particles by further cutting, thereby improving the overall work efficiency.

[0013] 2. The utility model is provided with a conveying mechanism and a closing mechanism through a receiving mechanism, and the rubber particles screened through fall into a storage tank, and the storage tank is installed on the surface of the conveyor belt, and the positioning block is fixed on the surface of the conveyor belt and stabilizes the storage tank between the positioning blocks to prevent accidents of sliding. When the storage tank is nearly full, the closing mechanism starts to open the gate, and the gates on both sides of the load-bearing frame move toward the middle driven by a synchronous motor until the two gates fit together to complete the closure of the feed pipe, and then driven by a driving motor, the full storage tank is moved by the conveyor belt until the next empty tank moves to the bottom of the feed pipe and the gate is opened again, and the staff only needs to unload the originally full storage tank and complete the replacement of the storage tank at the end, which greatly reduces the work intensity of the staff, reduces physical consumption, and reduces harm to the body.
