Description

Technical Field

[0001] This invention relates to the field of rubber secondary processing technology, and in particular to a high-efficiency crushing device for waste rubber products used in the production of sealing strips. Background Technology

[0002] Sealing strips are typically made of rubber, thanks to its excellent elasticity and sealing properties, making it widely used in sealing strip production. In the manufacturing process, some sealing strips are made from recycled waste rubber products. However, during the processing, storage, and use of rubber and its products, their properties and structure may change due to the combined effects of various internal and external factors, leading to a loss of usability. This aging phenomenon manifests as cracking, stickiness, hardening, softening, powdering, discoloration, and mold growth. Due to aging, the rubber's properties change, leading to its disposal. However, considering that rubber is a difficult-to-degrade substance, we need to process it, such as crushing it into rubber granules to increase its degradation rate, or recycling the rubber granules as reusable materials.

[0003] For example, patent CN107552195A discloses a rubber crusher, which includes: a housing, a feed inlet, and a first motor. The feed inlet is connected to the top of the housing, and the first motor and the second motor are respectively installed on the left and right side walls of the housing. Both the first motor and the second motor are located on the top of a placement plate, which is fixedly installed on the outer wall of the housing. This invention uses spiral blades to first cut the rubber into smaller pieces, preventing the blades from getting stuck during crushing. The rubber is then filtered through a screen to prevent unsuitable particles from falling through, avoiding repeated crushing and wasting time. A rotating shaft drives the screen to rotate, and the action of moving between the first and second fixed blocks causes the screen to vibrate up and down, further crushing unsuitable particles. This effectively improves the crushing efficiency, making it practical and suitable for widespread promotion and use.

[0004] However, currently, traditional rubber crushing equipment mainly crushes waste rubber products that have been used for a long time, such as tires and hoses. Their surfaces are often covered with a large amount of dirt, stones and other debris. When crushing these rubber products, the debris adhering to the surface of the rubber products can easily collide with the crushing blades, greatly increasing the wear of the blades and even causing damage to the blades. This seriously increases the cost of rubber crushing and recycling. At the same time, existing rubber crushing equipment often directly crushes waste rubber products. Although waste rubber products have a certain degree of aging, they still have a certain degree of elasticity and toughness, which greatly increases the difficulty of crushing, prolongs the crushing time, and results in low work efficiency. Summary of the Invention

[0005] In view of this, the present invention provides a high-efficiency crushing device for waste rubber products used in the production of sealing strips. It has a cleaning chamber and a cleaning mechanism. The device cleans the surface of the rubber products by means of a water storage component and a brush of the cleaning component. Then, the device scrapes off stubborn adhesive debris by means of the triangular protrusion of the cleaning chamber. This removes the debris from the surface of the rubber products in advance and prevents the debris from colliding with the blades of the crushing roller and causing damage to the blades.

[0015] Beneficial effects

[0016] According to various embodiments of the present invention, the rubber crushing equipment, compared with traditional rubber crushing equipment, has a cleaning mechanism. When the rubber product passes through the cleaning mechanism, it will squeeze the brush, thereby causing the upper and lower cleaning parts to move upward and downward respectively, squeezing the water storage part, causing the brush to absorb water and clean the rubber product. At the same time, the rubber in the cleaning chamber moves to the left under the conveying roller. When it passes the triangular protrusion of the cleaning chamber, it will be scraped by the triangular protrusion, scraping off the debris on the surface of the rubber. This prevents debris on the surface of the rubber product from colliding with the blades of the crushing roller, which would cause severe wear or even damage to the blades, leading to increased costs.

[0017] In addition, as mentioned above, the triggering method of the cleaning mechanism can effectively reduce the waste of water during the cleaning process, and at the same time avoid excessive moisture on the surface of rubber products. With appropriate moisture, the crushed rubber particles can have a certain degree of adhesion, reducing the generation of dust, and also preventing moisture accumulation after crushing, which would make the rubber particles soaked in water and inconvenient to recycle.

[0018] Furthermore, after the rubber products are sent out of the cleaning chamber, they are cut into strips by the cutting components. Compared to crushing the rubber products as a whole, the strip-shaped rubber products have a larger contact area with the crushing rollers, and the rubber is subjected to greater torque during the crushing process. At the same time, the refrigeration unit is connected to the outside air, and low-temperature gas is sent into the guide chamber of the crushing chamber through the air inlet. After the rubber products are cut by the cutting mechanism, they pass through the guide chamber. During this process, the low-temperature gas cools down the rubber products, causing them to harden, reducing their toughness, and increasing their brittleness. This makes the rubber products easier to crush in the crushing mechanism, and the resulting rubber particles are finer, which can effectively increase the crushing efficiency.
