Description

Technical Field

[0001] This utility model belongs to the field of rubber technology, and specifically relates to a device for sieving and crushing pulverized rubber. Background Technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, capable of significant deformation under small external forces, and returns to its original shape after the force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a very high molecular weight, often exceeding hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is made from the latex extracted from rubber trees, rubber grass, and other plants; synthetic rubber is obtained through the polymerization of various monomers. Rubber products are widely used in various aspects of industry and daily life.

[0003] With the development of rubber products and the recycling of resources, rubber crushing devices can break waste rubber products into smaller particles or powders, providing the possibility for subsequent resource reuse. However, when using general crushing devices, the single crushing effect is poor, and they cannot effectively perform multi-screening and crushing, which affects the use effect. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a device for easily screening and pulverizing crushed rubber, which solves the problem of poor single-stage pulverization effect and inability to effectively perform multi-stage screening and pulverization, thus affecting the performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for facilitating the screening and crushing of pulverized rubber, comprising a base plate and a screening and crushing box. A collection box is provided on the top of the base plate and is located at the bottom of the screening and crushing box. A box cover is provided on the top of the screening and crushing box, and a crushing box is provided on the top of the box cover. A feed hopper is provided on the top of the crushing box. A second motor is provided on one side of the crushing box. The output end of the second motor is connected to a first rotating shaft. A first crushing blade is respectively provided on the surface of the first rotating shaft. A second sprocket is connected to one end of the first rotating shaft. A first chain is provided on the surface of the second sprocket, and a first chain is provided inside one end of the first chain. The device includes a first sprocket, a second rotating shaft on one side of the first sprocket, and cams on the surface of the second rotating shaft. An n-shaped filter plate is installed inside the screening and crushing box, with the cams contacting the n-shaped filter plate. A triangular support frame is installed inside the n-shaped filter plate, with springs at the bottom of the triangular support frame and a fixing plate at the bottom of the springs, connected to the inner wall of the screening and crushing box. Arc-shaped support plates are installed at both ends inside the screening and crushing box, with second filter holes on the surface of each arc-shaped support plate. A third rotating shaft is installed on the upper side of each arc-shaped support plate, with second crushing blades on the surface of each third rotating shaft.

[0006] Preferably, the inside of the crushing box is equipped with baffles, and one end of the baffle is located above the first crushing blade.

[0007] Preferably, threaded holes are provided around the four sides of the box cover surface, and the threaded holes extend to the inner wall of the screening and crushing box, and bolts are threaded inside the threaded holes.

[0008] Preferably, the bottom of the triangular support frame is provided with sliding rods at both ends, and one end of the sliding rod slides through the fixing plate.

[0009] Preferably, a first motor is provided on one side of the screening and crushing box, and the output end of the first motor is connected to a third rotating shaft. A third sprocket is provided at one end of the third rotating shaft, and a second chain is provided on the surface of the third sprocket.

There are four sets of electro-hydraulic push rods, and they are all powered by the same source.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In operation, the rubber to be crushed is poured into the feed hopper. The second motor is then activated, driving the first crushing blade via the first rotating shaft. This initial crushing action crushes the rubber, which then falls onto the surface of an n-shaped filter plate inside the sieving and crushing chamber. Simultaneously, the first rotating shaft, through a second sprocket, a first chain, and another sprocket, drives the second rotating shaft and a cam. The cam then moves the n-shaped filter plate up and down, creating a sieving effect. Small rubber particles pass through the first filter holes, while larger particles fall into the arc-shaped support plate. The first motor then activates, driving the third rotating shaft and the second crushing blade for further crushing. The crushed rubber then falls through the second filter holes. This multi-stage crushing and sieving process ensures better crushing and increases the overall crushing efficiency. Attached Figure Description
