[0001] The invention relates to a pulverizing device, in particular to a raw material pulverizing device for producing rubber cushion belts, which is applied in the technical field of rubber raw material pulverizing. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature. Rubber is divided into natural rubber and synthetic rubber. Natural rubber is processed from the gum extracted from rubber trees, rubber grass and other plants, while synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in various aspects of industry or life. The raw material crusher for rubber belt production is a machine that crushes large-sized rubber raw materials into required sizes.

[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figure 1-Figure 6 A raw material crushing device for rubber pad production is shown, including a crushing mechanism 1, which includes a crushing support shell 101, and a crushing roller 102 is rotatably connected to the inner wall of the crushing support shell 101. The crushing roller 102 is fixedly connected to the output end of a driving member 1. A pair of crushing rollers 102 are provided, and the two crushing rollers 102 rotate towards each other. The driving member 1 is installed with the crushing support shell 101, and the driving member 1 is used to drive the crushing roller 102 to rotate. A speed sensor 1 and a temperature sensor are provided in the crushing roller 102, and a crushing intelligent controller is provided on the outer wall of the crushing support shell 101. The driving member 1 is preferably an electric motor or a pneumatic motor. When crushing is required, the driving member 1 is actuated to drive the two crushing rollers 102 to rotate towards each other to crush the rubber raw materials.

[0031] The outer wall of the crushing support shell 101 is provided with a conveying mechanism 2 for conveying the rubber raw materials into the crushing mechanism 1 .

[0032] The outer wall of the crushing support shell 101 is provided with a cooling mechanism 3, and the cooling mechanism 3 includes a cooling support shell 301, and an air guide component is provided on the cooling support shell 301. The cooling support shell 301 is connected with the crushing support shell 101 through the air guide component. The cooling support shell 301 is connected with a refrigeration component 307, and the refrigeration component 307 is used to reduce the temperature of the inner cavity of the cooling support shell 301. The cooling support shell 301 is provided with an air pressure detection component 308, and the air pressure detection component 308 includes a detection support shell 309, and a gas pressure rod 310 is slidably connected in the detection support shell 309. The bottom of the inner wall of the detection support shell 309 is provided with a detection press Button 311, the air guide component sucks room temperature air into the cooling support shell 301. As the air guide component sucks in air, the air pressure in the cooling mechanism 3 gradually increases. The increased air pressure will cause the pneumatic rod 310 to be pressed into the interior of the detection support shell 309. When the pneumatic rod 310 moves to the bottom of the detection support shell 309, the detection button 311 will be triggered. After the detection button 311 is triggered, the air guide component stops sucking air and the refrigeration component 307 starts working, so that the gas temperature in the cooling support shell 301 is reduced. When the crushing roller 102 needs to be cooled, the cooling gas will be injected into the crushing support shell 101 through the air guide component, so that the crushing roller 102 will be cooled quickly.

[0033] The pulverizing intelligent controller is provided with a main control module, a command module and a detection module. The main control module is electrically connected to the command module and the detection module respectively. The command module is electrically connected to the driving member 1, the transmission mechanism 2, the air guide component and the refrigeration component 307 respectively. The detection module is electrically connected to the speed sensor 1, the temperature sensor and the detection button 311 respectively.

[0034] Before the rubber raw material is crushed, the main control module controls the air guide component to fill the cooling support shell 301 with gas through the command module. The air guide component includes a conduit 1 302, which is connected to the cooling support shell 301. An air pump 303 and a solenoid valve 1 304 are respectively installed on the conduit 1 302. The cooling support shell 301 is connected to the crushing support shell 101 through a conduit 2 305. A solenoid valve 2 306 is arranged on the conduit 2 305. The command module is respectively connected to the air pump 303, the solenoid valve 1 304, and the solenoid valve 2 306 is electrically connected, the command module controls the solenoid valve 304 and the air pump 303 to open, and the room temperature air is filled into the cooling support shell 301. As the air is filled, the air pressure inside the cooling support shell 301 increases. Since the air pressure inside the cooling support shell 301 is greater than the air pressure inside the detection support shell 309, the pneumatic rod 310 moves toward the inside of the detection support shell 309. The main control module collects the status data of the detection button 311 through the detection module. When the pneumatic rod 310 triggers the detection button 311, the command module controls the solenoid valve 304 and the air pump 303 to open, and the room temperature air is filled into the cooling support shell 301. As the air pressure inside the cooling support shell 301 is greater than the air pressure inside the detection support shell 309, the pneumatic rod 310 moves toward the inside of the detection support shell 309. 1 304 and the air pump 303 are closed, and then the refrigeration component 307 is controlled to work. The refrigeration component 307 includes a refrigerator 312, which penetrates and is embedded in the cooling support shell 301. The refrigerator 312 matches the inner wall of the cooling support shell 301. A support cover 313 is fixedly installed on the refrigerator 312, and the support cover 313 is fixedly connected to the cooling support shell 301. The instruction module is electrically connected to the refrigerator 312. The refrigeration component 307 is used to cool the compressed gas in the cooling support shell 301 to reach a set temperature (the set temperature in the current state is preset in the main control module), so that the crushing roller 102 can be quickly cooled. The instruction module controls the refrigerator 312 to work to cool the compressed gas in the cooling support shell 301. The temperature of the compressed gas can be controlled by adjusting the working time and intermittent time of the refrigerator 312, so that the compressed gas maintains the required low temperature, and can maintain a good effect when the crushing roller 102 needs to be cooled. At the same time, the compressed gas can also absorb heat when expanding, further improving the cooling effect.

[0035] When the rubber raw material is crushed, the rubber raw material is placed on the conveying mechanism 2. The main control module controls the movement of the conveying mechanism 2 through the instruction module, and sends the raw material into the crushing support shell 101, which is crushed by the crushing roller. The instruction module controls the movement of the driving member 1 to drive the two crushing rollers to rotate towards each other, and crush the rubber raw material into rubber particles. The main control module collects the speed data 1 of the speed sensor 1 through the detection module, and compares the speed data 1 with the specified speed 1 (the main control module is preset with the specified speed 1 under the current state). When the speed data 1 is less than the specified speed 1, it means that the rubber melts during the crushing process and adheres to the crushing roller 102, so that the speed of the crushing roller 102 is reduced. At this time, the instruction module will control the speed of the driving member 1 to reduce, reduce the crushing rate of the crushing roller 102, so as to reduce the heating and melting of the rubber and maintain the quality of the produced rubber particles.

[0036] At the same time, the main control module detects the temperature data of the temperature sensor through the detection module, and compares the temperature data with the specified temperature (the specified temperature in the current state is preset in the main control module), and obtains the amount of cooling gas to be injected into the crushing support shell 101. If the temperature data is greater than the specified temperature, the instruction module controls the solenoid valve 2 306 to open, so that the cooling compressed gas cylinder is input into the crushing support shell 101 through the conduit 2 305. The cooling compressed gas absorbs the heat of the crushing roller 102, so that the heat of the crushing roller 102 is reduced. At the same time, the compressed gas further absorbs heat when it expands, so that the heat of the crushing roller 102 is further increased. The temperature is lowered until the difference between the temperature data and the specified temperature is within a certain error range, and the instruction module controls the solenoid valve 2 306 to close; the main control module can judge the difference between the temperature data and the specified temperature. When the difference between the temperature data and the specified temperature is small, the opening degree of the solenoid valve 2 306 is low. When the difference between the temperature data and the specified temperature is large, the opening degree of the solenoid valve 2 306 is high. The difference between the temperature data and the specified temperature is proportional to the opening degree of the solenoid valve 2 306, thereby realizing rapid cooling of the crushing roller 102, while reducing the waste of resources, improving the cooling efficiency, and saving the cooling cost.

[0037] After opening the solenoid valve 2 306 to inject cooling gas into the crushing roller 102, the air pressure in the cooling support shell 301 drops, and the detection button 311 is no longer triggered. The command module controls the solenoid valve 1 304 and the air pump 303 to open again, and fills the cooling support shell 301 with gas until the detection button 311 is triggered again. The command module controls the solenoid valve 1 304 and the air pump 303 to close, waiting for the next cooling of the crushing roller 102.

[0038] The second implementation method:

[0039] Figure 1-Figure 5 and Figure 7-Figure 8A raw material crushing device for rubber pad production is shown. Different from the first embodiment, a water reservoir 4 is additionally provided below the conveying mechanism 2, and the water reservoir 4 is fixedly connected to the crushing support shell 101. A cleaning mechanism 5 is connected through the water reservoir 4, and the cleaning mechanism 5 includes a nozzle 503. The nozzle 503 is arranged directly above the corresponding conveyor belt 203. The nozzle 503 is connected to the water reservoir 4 through a conduit three 501. A water pump 502 is arranged on the conduit three 501. The instruction module is electrically connected to the water pump 502. When the water pump 502 is started, the water in the water reservoir 4 is transported to the nozzle 503 through the conduit three 501, and the nozzle converts the water into water mist and sprays it onto the rubber raw material. The cleaning mechanism 5 is used to clean the rubber raw material before crushing, so that the rubber raw material can be directly used after being crushed into rubber particles without cleaning, thereby improving the production line efficiency.

[0040] The transmission mechanism 2 includes a transmission base 201, on which a transmission shaft 202 is rotatably connected, and a conveyor belt 203 is sleeved on the transmission shaft 202. The transmission shaft 202 is fixedly connected to the output end of the second driving member, and the second driving member is installed on the transmission base 201. The second driving member is used to drive the transmission shaft 202 to rotate. A speed sensor 2 is arranged on the transmission shaft 202. The instruction module is electrically connected to the second driving member, and the detection module is electrically connected to the second speed sensor. The movement of the second driving member drives the transmission shaft 202 to move, and the movement of the transmission shaft 202 drives the conveyor belt 203 to move. The rubber raw material placed on the conveyor belt 203 will affect the speed of the transmission shaft 202. The quality of the rubber raw material placed on the conveyor belt 203 can be obtained through the second speed sensor, thereby adjusting the power of the cleaning mechanism 5; the rubber raw material will be contaminated with dust and other impurities during transportation, and needs to be cleaned after crushing before proceeding with subsequent processes, which is inconvenient.

[0041] When the rubber raw material is crushed, the instruction module controls the action of the second driving member, which is preferably an electric motor or a pneumatic motor. The action of the second driving member drives the transmission shaft 202 to move, and the action of the transmission shaft 202 drives the conveyor belt 203 to move, so that the rubber raw material is placed on the transmission belt. The main control module collects the speed data 2 of the speed sensor 2 through the detection module, and compares the speed data 2 with the specified speed 2. When the speed data 2 is less than the specified speed 2, it is judged that the rubber raw material is placed on the conveyor belt 203. The instruction module controls the water pump 502 to open, and the nozzle 503 sprays water mist to clean the rubber raw material on the conveyor belt 203. The greater the difference between the speed data 2 and the specified speed 2, the higher the power of the water pump 502 controlled by the instruction module is, so as to adjust the amount of water sprayed according to the rubber raw material, so that each piece of rubber raw material can be fully cleaned; when the difference between the speed data 2 and the specified speed 2 is within a certain error range, it is judged that there is no rubber raw material placed on the conveyor belt 203, and the instruction module controls the water pump 502 to stop moving and stop spraying water mist.

[0042] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
