Description

Technical Field

[0001] The invention relates to the technical field of rubber preparation crushers, in particular to a raw material crushing processing device for rubber preparation. Background Art

[0002] In the rubber production process, raw material crushing is a crucial link. The particle size of the raw materials directly affects the quality and performance of subsequent rubber products. However, in the existing rubber production raw material crushing processing technology, there are generally some problems, which limit production efficiency and increase production costs.

[0003] Specifically, existing crushing equipment often cannot ensure the uniformity of raw material particle size during the crushing process. Due to the physical properties of the raw materials (such as hardness, toughness, etc.) and the design limitations of the crusher, the raw materials after crushing are often of different sizes, including fine particles and larger lumps. This uneven crushing result requires multiple screening and repeated crushing to meet the requirements of the subsequent process for the raw material particle size.

[0004] In addition, in the existing crushing process, the screening and re-crushing steps usually require manual participation. That is, after the crusher completes the first crushing, the crushed raw materials need to be screened manually to screen out the lumps that do not meet the particle size requirements, and then poured back into the crusher for secondary crushing. This manual operation is not only inefficient and increases labor costs, but also easily causes waste and pollution of raw materials during the screening and re-crushing process.

Subsequently, the crushed rubber material naturally falls into the filter bin below under the action of gravity. After fine filtration by the filter screen, the rubber particles that meet the particle size requirements pass through the filter screen smoothly and are discharged at the bottom of the filter bin for subsequent processing. This design not only improves production efficiency, but also ensures the uniformity of the particle size and quality stability of the product. At the same time, by driving the vibration motor, the filtration efficiency can be improved, making the entire crushing and filtration process more efficient and smooth.

[0027] Furthermore, an inspection plate 9 is installed on the outer surface of one side of the filter bin 8 through multiple sets of bolts 616. The inspection plate 9 provides a convenient maintenance and inspection channel for the operator, which not only facilitates the cleaning and replacement of the filter screen, but also improves the maintenance efficiency and reliability of the entire device.

[0028] Working principle: First, the rubber raw material to be crushed is put into the crushing chamber 3. Then, the first motor 4 is started, and the motor drives the connecting shaft 514 to rotate through the shaft coupling 5, thereby driving the crushing roller 7 in the crushing chamber 3 to start the crushing operation. The rotating motion of the crushing roller 7 cuts, impacts and grinds the rubber raw material into smaller particles.

[0029] The crushed rubber material naturally falls into the filter bin 8 below under the action of gravity. Inside the filter bin 8, the material is finely filtered by the filter screen 912. The rubber particles that meet the particle size requirements pass through the filter screen smoothly and are discharged at the bottom of the filter bin 8 for subsequent processing. The driving vibration motor 911 can improve the efficiency of filtering.

[0030] For those rubber materials that fail to pass through the filter due to their large particle size, they will remain on the upper surface of the filter 912. In order to deal with these unqualified materials, the device is equipped with an adsorption mechanism. The second motor 812 is started, and the motor drives the rotating shaft 512 to rotate, thereby driving the fan blade 513 to rotate to generate suction. This suction is transmitted to the rubber hose 817 through the connecting pipe 814, and finally reaches the adsorption cover 717.

[0031] The suction cover 717 is located at the top of the filter screen 912, and its strong suction can easily absorb the rubber material remaining on the screen. The absorbed material is then sent to the installation shell 813, and then the material falls back into the crushing bin 3 through the material discharge chute at the bottom of the installation shell 813 for secondary crushing.

[0032] In order to improve the efficiency and accuracy of the adsorption operation, the device is also equipped with a movable mechanism. The third motor 716 is started, and the motor drives the screw 718 to rotate. The rotational motion of the screw 718 is converted into the linear motion of the slide 714, which in turn drives the U-shaped connecting plate 713 and the adsorption cover 717 thereon to move back and forth on the top of the filter screen 912. This mobile adsorption operation can ensure that every corner on the filter screen 912 can be carefully cleaned, thereby minimizing the residue of unqualified materials. In order to reduce the vibration and noise that may be generated by the device during operation, a shock absorbing mechanism is set on the outer surfaces of both sides of the filter bin 8. The mechanism consists of a damper 613 and a spring 614, which can effectively absorb and disperse vibration energy.

[0033] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
