Description

Technical Field

[0001] The utility model belongs to the technical field of rubber production, in particular to a raw material crusher for rubber additives. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce a large deformation under a very small external force. It can return to its original shape after the external force is removed. Rubber products are widely used in transportation, industrial mining, agricultural water conservancy, military, civil engineering, electrical communications, medical care, culture, education and sports. Rubber products used in different fields often require different properties. Therefore, a variety of additives need to be added during the rubber production and processing to improve the aging resistance, elasticity, viscosity, etc. of the rubber. During the processing of rubber additives, the raw materials need to be crushed to powders of a certain particle size so that they can be quickly and fully mixed with the rubber raw materials. Crushing the additive raw materials by a crusher can greatly reduce the labor intensity of the staff and improve production efficiency. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with publication number CN212385785U discloses a rubber stirring pulverizer device, wherein the bottom of the feed bin is connected to the mixing chamber, a motor a is installed inside the mixing chamber, one side of the motor a is fixedly connected to the rotating shaft a, one side of the rotating shaft a is connected to the reverse support rod, and both sides of the reverse support rod are fixedly connected to crushing knives, a motor b is installed directly below the motor a, and one side of the motor b is fixedly connected to the rotating shaft b. The pulverizer device usually crushes the material by the crushing knife, but during the long-term friction process, the temperature of the crushing knife gradually increases. Crushing the material at high temperature will accelerate the damage of the crushing knife and increase the maintenance cost of the device;

[0004] 2. When the raw materials of rubber additives are crushed, the raw materials need to be crushed into a specified particle size. Small particles of raw material powder are small in size and light in weight. During the crushing process, the rapidly rotating crushing knife often causes a large amount of raw material powder to be blown up by the wind, which makes it difficult for the powder to quickly pass through the screen and discharge, thus reducing the processing speed. Utility Model Content

[0005] The utility model aims to provide a raw material crusher for rubber additives. Through a crushing frame, a crushing barrel and a discharging box, the utility model solves the problems that when the raw material crusher for rubber additives crushes materials, the long-term friction between the crushing knife and the material will cause the temperature of the crushing knife to rise, and the long-term work will shorten the service life of the crushing knife. The raw material powder with fine particles is easily blown away by the wind during the crushing process, which is not convenient for rapid screening and discharging.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a raw material crusher for rubber additives, comprising a crushing frame, a crushing barrel and a discharging box, wherein one side of the crushing frame is penetrated and clamped with two crushing rollers, the bottom of the crushing frame is clamped and fixed with a crushing barrel, a rotating rod is arranged at the center of the inner side of the crushing barrel, a crushing knife is clamped and fixed on the outer peripheral surface of the rotating rod, a discharging box is clamped and fixed on the outer peripheral surface bottom of the crushing barrel, a mesh conveyor belt is penetrated and inserted on one side of the discharging box, a water pump is penetrated and clamped on the bottom of the other side of the discharging box, a spray pipe is arranged on the top of the water pump, the spray pipe is suspended from the top of the crushing knife, and an exhaust fan is clamped and fixed on the inner side of the discharging box;

[0008] The co-directional rotation of the crushing rollers can crush large particles of raw materials, which is convenient for the crushing knife to carry out further crushing processing and reduce the workload of the crushing knife. The rotation of the rotating rod can further drive the rotation of the crushing knife, so that the crushing knife can rotate quickly to crush the raw materials. During the crushing process, the water pump pumps the water inside the discharge box into the spray pipe, and sprays it on the inside of the crushing barrel through the spray pipe to cool the crushing knife and humidify the raw material powder at the same time to increase the weight of the raw material powder and prevent the powder from being lifted up by the air flow, so that the raw material powder can be discharged quickly. The mesh conveyor belt can drive the sieved raw material powder to be discharged, and the excess water can flow back to the bottom of the discharge box through the mesh conveyor belt. The exhaust fan draws air downward, which can increase the screening speed of the raw material powder again, and the raw material powder falling on the surface of the mesh conveyor belt can be air-cooled and dried.

[0009] Furthermore, a hopper is welded and fixed on the top of the crushing frame, a material passage is opened through the top of the crushing frame, the two crushing rollers are rotatably clamped on the inner side of the material passage, one end of the two crushing rollers is clamped with a first transmission assembly, the other side of the first transmission assembly is clamped with a first crushing motor, and the first crushing motor is connected to the two crushing rollers through the first transmission assembly;

[0010] The first pulverizing motor can drive the two pulverizing rollers to rotate in the same direction, thereby performing preliminary pulverizing processing on large-particle materials, reducing the workload of the pulverizing knife and extending the service life of the pulverizing knife.

[0011] Furthermore, a guide frame is welded through the bottom of the crushing barrel, a second transmission assembly is clamped through the outer peripheral surface of the crushing barrel, the rotating rod is rotatably clamped on one side of the top of the second transmission assembly, and a second crushing motor is clamped on the other side of the top of the second transmission assembly, and the second crushing motor is connected to the rotating rod through the second transmission assembly;

[0012] The guide frame can guide the raw material powder so that it falls stably onto the upper side of the mesh conveyor belt. The second crushing motor drives the crushing knife to rotate, which can further crush the raw material and improve the automation degree of the crusher.

[0013] Furthermore, a screen is clamped and fixed on the inner side of the crushing barrel, the rotating rod is inserted through the center of the bottom of the screen, and the crushing knife is attached to the top of the screen;

[0014] After the raw materials are crushed to a specified particle size, they can be sieved through a screen to ensure the quality of the raw material powder discharged.

[0015] Furthermore, a water inlet pipe and a drain pipe are welded through one end of the discharge box from top to bottom, the water inlet pipe and the drain pipe are located at the bottom of the exhaust fan, a water pipe is inserted through the top of the outer peripheral surface of the water pump, the spray pipe is connected to the top of the water pipe, and the water pipe is inserted through the outer peripheral surface of the crushing barrel;

[0016] The water at the bottom of the discharge box can be pumped into the spray pipe through the water pump and sprayed on the crushing box to humidify the raw material powder, increase the weight of the powder, and prevent the powder from being lifted up by the airflow. At the same time, the crushing knife is cooled to prevent the crushing knife from shortening its service life due to overheating and reduce maintenance expenses. At the same time, the downward flowing air speeds up the speed of the raw material powder passing through the screen and improves production efficiency.

[0017] Furthermore, a rotating motor is inserted through one end of the discharge box, the rotating motor is connected to the mesh conveyor belt, a support frame is inserted through one side of the mesh conveyor belt, a discharge port and an air outlet are inserted through one side of the discharge box from top to bottom, the mesh conveyor belt is inserted through one side of the discharge port, and the exhaust fan is located between the discharge port and the air outlet;

[0018] After the powder falls onto the surface of the mesh conveyor belt, the mesh conveyor belt is driven to rotate by the rotating motor, which further drives the powder to be discharged through the discharge port. During the discharge process, moisture can flow back to the bottom of the discharge box through the mesh conveyor belt, and the flowing air can air-cool and dry the raw material powder.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model solves the problem that the pulverizer device usually pulverizes materials through a pulverizing knife, but the temperature of the pulverizing knife gradually increases during the long-term friction process. Pulverizing the material at a high temperature will accelerate the damage of the pulverizing knife and increase the maintenance cost of the device. The raw materials can be initially crushed and pulverized by the rotation of the pulverizing roller, reducing the workload of the pulverizing knife. When the pulverizing knife rotates to pulverize the raw materials, the water pump draws water in the discharge box into the pulverizing barrel and sprays it on the surface of the pulverizing knife to cool the pulverizing knife, thereby avoiding the shortening of the service life of the pulverizing knife due to overheating and reducing maintenance costs.

[0021] 2. The utility model solves the problem that when the raw materials of rubber additives are crushed to a specified particle size, the small-particle raw material powder is small in volume and light in weight. During the crushing process, the rapidly rotating crushing knife often drives a large amount of raw material powder to be blown up by the wind, which makes it inconvenient for the powder to quickly pass through the screen and be discharged, thereby reducing the processing speed. The water pumped into the crushing barrel is sprayed on the surface of the raw material powder, which increases the weight of the raw material powder and prevents the raw material powder from being blown up by the airflow. The exhaust fan draws air downward, which can drive the raw material powder to move downward, increase the speed of the raw material powder being sieved and discharged, and improve the processing efficiency.
