Description
Technical Field
[0001] This utility model relates to the technical field of wear-resistant rubber processing, specifically to a wear-resistant rubber internal mixer. Background Technology
[0002] Wear-resistant rubber is a high-wear-resistant material made from natural rubber, synthetic rubber, or mixtures thereof as raw materials. It is produced by optimizing the vulcanization system, reinforcing fillers, and antioxidants, combined with liquid nanotechnology or fiber reinforcement technology. Aircraft tires use environmentally friendly tires to reduce environmental pollution, lower energy consumption, and reduce carbon emissions. In addition, the rubber material of environmentally friendly tires is softer and has better grip, which improves driving safety. In the production process of aircraft tires, wear-resistant rubber is usually used as the basic raw material. The closed rubber mixing mill, also known as a kneading mill, is mainly used for the plasticizing and mixing of rubber.
[0003] For example, Chinese utility model patent CN213227084U discloses an environmentally friendly tire internal mixer, including a housing. A feed shell is fixedly connected to the upper end of the housing. The housing is arc-shaped. Rotors are rotatably connected to the inner sidewalls of the front and rear ends of the housing via two rotating shafts. Grinding blades are fixedly connected to the sidewalls of both rotors. A counter-blade, matching the grinding blades, is circumferentially connected to the inner sidewall of the housing. A lifting motor is fixedly connected to the upper end of the feed shell. The output shaft of the lifting motor passes through the sidewall of the feed shell and is fixedly connected to a push rod. A U-shaped plate is fixedly connected to the lower end of the push rod. The U-shaped plate is slidably connected to the left and right sidewalls of the feed shell. An extrusion block matching the two rotors is fixedly connected to the lower end of the U-shaped plate. This utility model improves the mixing efficiency and quality of the equipment and is convenient for users.
[0004] However, the existing devices mentioned above cannot effectively filter materials with poor friction effects or larger pieces, which not only reduces the grinding effect of the device on the materials, but also affects the subsequent use of the materials. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a wear-resistant rubber compound internal mixer that facilitates the filtration of ground materials, improves the filtration efficiency of the device, ensures the final use effect of the materials, and enhances its practicality.
[0006] This utility model discloses a wear-resistant rubber compound internal mixer, comprising a shell, a door rotatably installed on the bottom region of the outer side wall of the shell, a grinding chamber fixedly installed in the top region of the inner side of the shell, a feed pipe connected to the top of the grinding chamber, a discharge pipe connected to the bottom of the grinding chamber, a grinding mechanism arranged inside the grinding chamber, and a filtering mechanism arranged in the bottom region of the shell; the grinding mechanism includes a rotating shaft, which is laterally rotatably installed on the inner side wall of the shell, and rollers fixedly installed on the outer side wall of the rotating shaft;
[0007] The filtration mechanism includes a guide tube with two symmetrically fixed support plates at its bottom end. A limit rod is horizontally fixed on the inner wall of the housing, and the limit rod is slidably connected to one of the support plates. A reciprocating screw is horizontally rotatably mounted on the inner wall of the housing, and the reciprocating screw is screwed to the other support plate. A connecting shaft is rotatably mounted on the inner wall of the housing, and a fixing plate is fixedly mounted on the outer wall of the connecting shaft. A filter screen is fixedly mounted in the middle area of the fixing plate. This wear-resistant rubber internal mixer rotates the rotating shaft simultaneously, driving the rollers to rotate. The rotating rollers and the inner wall of the grinding chamber compress the material, thereby purifying it. In the grinding operation, the ground raw material is discharged through the discharge pipe. Simultaneously, the rotating reciprocating screw drives the support plate and guide tube to move laterally under the limit of the limiting rod. The material discharged through the discharge pipe is guided by the guide tube and then discharged through the bottom of the guide tube. The material is then filtered by the filter screen on the fixed plate. The connecting shaft drives the fixed plate to rotate, thereby filtering the material discharged from the guide tube in different areas in different zones. This facilitates the filtration of the ground material, improves the filtration efficiency, ensures the final product's performance, and enhances practicality.
[0008] Preferably, a guide plate is fixedly installed on the inner wall of the grinding chamber, a plurality of first grinding rods are fixedly installed on the outer wall of the guide plate, and a plurality of second grinding rods are fixedly installed on the outer wall of the roller. The installation of the guide plate and the first grinding rods facilitates the guiding of the material to be ground, and facilitates the rapid grinding of the material by the rotating roller, the second grinding rods and the first grinding rods.
[0009] Preferably, two partitions are symmetrically fixedly installed on the top of the fixed plate, and two auxiliary plates are symmetrically fixedly installed on both ends of each partition. The installation of the partitions and auxiliary plates facilitates the rapid guiding of the material after it has passed through the filter screen.
[0010] Preferably, two first collection slots and a second collection slot are symmetrically slidably installed at the bottom of the inner side of the housing. By installing the first collection slots and the second collection slots, it is convenient to quickly collect the raw materials after they have passed through the filter screen.
[0011] Preferably, a baffle is fixedly installed at the top of the discharge pipe. By installing the baffle, it is convenient to quickly guide the ground raw material into the interior of the discharge pipe for discharge.
[0012] Preferably, two limiting plates are symmetrically fixedly installed on the limiting rod. Both limiting plates have through holes inside. The reciprocating screw is located inside the through holes on the limiting plates. By installing the limiting plates, the limiting plates fit into the bottom area of the guide tube, thereby effectively limiting the sliding guide tube.
[0013] Preferably, a first motor is fixedly installed at one end of the reciprocating screw, and the first motor is fixedly installed on the outer side wall of the housing. A second motor is fixedly installed at one end of the rotating shaft, and the second motor is fixedly installed on the outer side wall of the housing. By installing the first motor and the second motor, it is convenient to provide power support for the reciprocating screw and the rotating shaft.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This wear-resistant rubber compound internal mixer rotates the rotating shaft simultaneously, driving the rollers to rotate. The rotating rollers and the inner wall of the grinding chamber compress the material, thereby grinding the material. The ground raw material is discharged through the discharge pipe. Simultaneously, the rotating reciprocating screw drives the support plate and guide tube to move laterally under the limit of the limiting rod. The material discharged from the discharge pipe is guided by the guide tube and discharged through the bottom end of the guide tube. The material is filtered by the filter screen on the fixed plate. The connecting shaft drives the fixed plate to rotate, thereby filtering the material discharged from the guide tube in different areas. This facilitates the filtration of the ground material, improves the filtration efficiency of the device, ensures the final use effect of the material, and enhances its practicality.
