Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber processing equipment technology, and more specifically to a crushing device for rubber processing. Background Technology
[0002] Rubber is a highly elastic polymer material with reversible deformation, exhibiting elasticity at room temperature. As a completely amorphous polymer, rubber often has a very high molecular weight, exceeding hundreds of thousands. Early rubber was derived from the latex of rubber trees and rubber grasses, processed into an elastic, insulating, waterproof, and airtight material. The production of rubber products generates waste, which is a reusable resource. To save costs, this waste is often crushed and recycled. Existing crushing devices typically use crushing rollers for compression crushing, and only crush once. This crushing effect is insufficient for processing requirements, often requiring workers to repeatedly crush the rubber a second or multiple times, resulting in high labor intensity and unsatisfactory crushing results. To address these problems, the inventors propose a crushing device for rubber processing. By incorporating upper and lower crushing rollers for double crushing of rubber waste, and then further pulverizing it with blades, the crushing effect is improved, making the rubber waste meet recycling standards and enabling recycling and reuse.
[0003] To improve the crushing effect and efficiency of rubber waste and enable its rapid recycling and reuse, Chinese Patent (Application Publication No.: CN119910806A) discloses a tire crushing equipment and method for pyrolysis of waste tires. This invention includes a crushing chamber formed by an inner steel liner, an annular air gap between the inner steel liner and the inner wall of the tank, a cylindrical electromagnet inside a rotating shaft tube, an electromagnetic control mechanism above the tank, a brush module electrically connected to the electromagnet, a photoelectric sensor module for sensing and detecting the real-time size of rubber particles in the crushing chamber on the top side of the tank, and a cooling mechanism above the tank. The air inlet of the cooling mechanism is connected to the crushing chamber, and the air outlet is connected to the annular air gap. This invention ensures crushing effect, improves the efficiency of the crushing process, and reduces crushing energy consumption to a certain extent.
[0004] The solution still has some shortcomings in application. Since rubber waste is usually large in volume in its initial state, it needs to be crushed into strips or granules before it can be easily cut. Otherwise, if it is cut directly, the effect is often not ideal and the time is relatively long, which is not conducive to improving the crushing efficiency. Therefore, it is necessary to improve the structure of the crushing device so that it can crush the rubber waste and then cut it, which can improve both the crushing efficiency and the crushing effect, and effectively improve the practical performance of the crushing device.

[0006] The technical solution adopted in this utility model is as follows:
[0007] A crushing device for rubber processing includes a crushing chamber comprising an upper chamber and a lower chamber. The upper chamber is respectively equipped with a first crushing component and a second crushing component arranged vertically. The first crushing component and the second crushing component include crushing rollers arranged in a front-to-back configuration. The outer ends of the crushing rollers are equipped with meshing gear discs. The lower chamber has a cavity in the middle of its inner side, which contains a bevel gear. A first rotating rod is mounted on the lower end of the bevel gear, and a plurality of crushing blades are mounted on the first rotating rod.

[0009] Furthermore, the upper cavity has a cuboid structure, and the lower cavity has a frustum-cone structure.
[0010] Furthermore, a second drive motor is mounted at the end of one of the gear disks.
[0011] Furthermore, the top of the cavity is hemispherical.
[0012] Furthermore, a sealing tube is provided between the cavity and the lower cavity, and the second rotating rod is disposed inside the sealing tube.

The crushing rollers on these assemblies first crush the rubber waste into strips or granules, preparing it for further crushing. Next, the rubber waste enters the lower cavity, where a first drive motor and bevel gear drive the crushing blades on a first rotating rod for a third stage of crushing, resulting in smaller particles or powder. Simultaneously, the dust generated during crushing is uniformly absorbed and treated by a suction fan to prevent it from scattering and polluting the environment. Finally, a sensor is installed in the lower cavity to prevent excessive feeding from affecting the crushing process. This invention is highly practical, featuring a novel structure, ingenious design, convenient operation, high crushing efficiency, and excellent crushing effect, making it suitable for widespread application.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0024] like Figures 1 to 4 As shown, a crushing device for rubber processing includes a crushing chamber 1, which includes an upper chamber 2 and a lower chamber 3. The upper chamber 2 is respectively equipped with a first crushing component 4 and a second crushing component 5 arranged vertically. The first crushing component 4 and the second crushing component 5 include crushing rollers 6 arranged front and rear. The outer ends of the crushing rollers 6 are equipped with meshing gear disks 7. The lower chamber 3 has a cavity 8 in the middle of its inner side. The cavity 8 contains a bevel gear 9. The bevel gear 9 is equipped with a first rotating rod 10 at its lower end. The first rotating rod 10 is equipped with several sets of crushing blades 11. The left end of the first rotating rod 10 is equipped with a second rotating rod 12. The second rotating rod 12 extends outward and is equipped with a first drive motor 13 at its end. A ventilation pipe 14 is provided on one side of the upper chamber 2.
[0025] Furthermore, a feed hopper 15 is installed in the middle of the top of the crushing chamber 1.
[0026] Furthermore, the upper cavity 2 has a cuboid structure, and the lower cavity 3 has a frustum-shaped structure.
[0027] Furthermore, a second drive motor 16 is mounted at the end of one of the gear disks 7.
[0028] Furthermore, the top of the cavity 8 is hemispherical.
[0029] Furthermore, a sealing tube 17 is provided between the cavity 8 and the lower cavity 3, and the second rotating rod 12 is disposed inside the sealing tube 17.
[0030] Furthermore, a sensor 18 is installed on the upper inner side of the lower cavity 3.
[0031] Furthermore, a suction fan 19 is installed at the end of the ventilation pipe 14.
[0032] Furthermore, the cavity 8 is provided with fixing rods 20 on the front and rear sides.
[0033] Furthermore, the lower cavity 3 is provided with a discharge port 21 on the lower front side, and the discharge port is provided with a cover.
[0034] Example: First, rubber waste enters the upper cavity 2 through the feed hopper 15 and is first crushed into strips by the crushing rollers 6 of the first crushing assembly 4. Then, it is crushed a second time by the crushing rollers 6 of the second crushing assembly 5, causing the rubber waste to fall into the lower cavity 3 in small strips or granules. Next, the first drive motor 13 is started to drive the second rotating rod 12 to rotate, which drives the first rotating rod 10 to rotate through the bevel gear 9. The rotation of the first rotating rod 10 drives several sets of crushing blades 11 to crush the rubber waste a third time. The process involves crushing rubber waste into small granules or powder. When the rubber waste in the lower cavity 3 reaches a certain capacity, the sensor 18 detects this and stops feeding to prevent excessive feeding from affecting the operation of the second crushing component 5. When several sets of crushing blades 11 are crushing, a certain amount of dust will be generated. The suction fan 19 is started to suck the dust out from the ventilation pipe 14 for unified treatment to prevent it from drifting out from the feed hopper 15 and affecting the environment. Finally, the cover is opened, and the rubber waste that has undergone triple crushing is taken out from the discharge port 21 for recycling.
