Description

Technical Field

[0001] The utility model relates to the field of rubber crushing, in particular to a rubber crushing machine for natural rubber production. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is very elastic at room temperature and can produce large deformation under the action of a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature (Tg) and a large molecular weight, often exceeding hundreds of thousands. Rubber is divided into natural rubber and synthetic rubber. Natural rubber is processed from the gum extracted from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry and various aspects of life.

[0003] The patent website discloses a natural rubber primary processing crusher (public announcement number: CN220657682U). This device uses a screen plate in conjunction with a lifting and tilting mechanism. The screen plate can screen out the natural rubber that still has large particles after being crushed by two sets of crushing rollers. The screen plate is lifted, and the lifting and tilting mechanism tilts the screen plate to one side of the collection tank. The large rubber particles screened out on the screen plate are poured into the collection tank, preventing large rubber particles from accumulating on the screen plate and causing blockage. At the same time, it reduces the workload of personnel in subsequently screening out larger natural rubber particles by themselves.

[0004] However, there are still some shortcomings in the natural rubber primary processing crusher of the above patent and the existing market: this device uses a screen plate to screen the crushed natural rubber particles, and after collecting the large particles, they need to be placed in the device for re-crushing. In order to completely crush them, the operation needs to be repeated many times, and pouring the large particles of natural rubber into the device depends entirely on manual operation of the staff, resulting in a large workload for the staff. Therefore, technical personnel in this field have proposed a natural rubber production crusher. Utility Model Content

The driving end of a motor 202 passes through the bracket 101 and is equipped with a second gear 203 that meshes with the first gear 201. The two sieve plates 104 divide the interior of the crushing box 103 into two storage chambers and a crushing chamber between the two. The inner top surface and the inner bottom surface of the crushing box 103 are both inclined. The two discharge ports 105 are respectively close to the two ends of the crushing box 103. Each feed port 107 is provided with a box door 106 that is compatible with it. Each box door 106 is provided with a door lock. The box door 106 of the upper feed port 107 is opened, and natural rubber can be placed in the crushing box 103 through the feed port 107. The first motor 202 drives the second gear 203 to rotate. The rotating second gear 203 drives the crushing box 103 to rotate one hundred and eighty degrees through the first gear 201.

[0025] See also Figure 3 and Figure 5 Two crushing rollers 4 are installed inside the crushing box 103 to rotate in the crushing chamber. One end of the two crushing rollers 4 extends to the outside of the crushing box 103 and is installed with a third gear 5 that meshes with each other. A second motor 3 is installed on the side of one of the crushing rollers 4 on the side of the crushing box 103. The driving end of the second motor 3 is fixedly connected to the other end of this crushing roller 4. When in use, the running second motor 3 drives the crushing roller 4 connected to its driving end to rotate. The rotating crushing roller 4 drives the other crushing roller 4 to rotate in the opposite direction through the two meshing third gears 5, and then the two third gears 5 rotate in opposite directions to crush the natural rubber passing through.

[0026] See also Figure 1 and Figure 6A water tank 7 filled with water is installed on the side of the crushing box 103 on the side of the second motor 3, and a semiconductor refrigeration plate 9 is installed on the inner wall of the water tank 7. The cooling end of the semiconductor refrigeration plate 9 faces the inside of the water tank 7, and the heating end of the semiconductor refrigeration plate 9 extends to the outside of the water tank 7. A spiral tube 8 is provided inside the water tank 7, one end of the spiral tube 8 extends to the inside of the crushing box 103 and is provided with a filter screen at the end, and the other end of the spiral tube 8 extends to the outside of the water tank 7 and is installed with a blower 10 fixed to the side of the water tank 7. When in use, the running semiconductor refrigeration plate 9 can cool the water in the water tank 7 to turn it into cold water. The running blower 10 injects air into the spiral tube 8. When the air flows through the spiral tube 8, it can exchange heat with the cold water in the water tank 7 to reduce the air temperature. After that, the air enters the crushing box 103 to accelerate the air circulation in the crushing box 103 while reducing the temperature in the crushing box 103, thereby avoiding the temperature increase of the natural rubber during the crushing process.

[0027] The working principle of the utility model is as follows: open the box door 106 of the upper feed port 107, put the natural rubber into the crushing box 103 through the feed port 107, and guide it into the space between the two crushing rollers 4 through the guide plate 6. The second motor 3 running in the same direction drives the crushing roller 4 connected to its driving end to rotate, and the rotating crushing roller 4 drives the other crushing roller 4 to rotate in the opposite direction through two meshing third gears 5, and then the two third gears 5 rotate in opposite directions to crush the natural rubber that passes through. After that, the rubber falls on the screen plate 104 below, and the screen plate 104 is used to screen the crushed rubber particles. Small particles After the particles enter the storage chamber, they are discharged from the lower discharge port 105, and the large particles remain above the screen plate 104. Then the first motor 202 drives the second gear 203 to rotate, and the rotating second gear 203 drives the crushing box 103 to rotate 180 degrees through the first gear 201. At the same time, the second motor 3 drives the crushing roller 4 to reverse. When the crushing box 103 rotates 180 degrees, the large particles of natural rubber will pass between the two crushing rollers 4 again, and the large particles will be crushed for the second time, and then screened again. The above operation is repeated to rotate the crushing box 103 until all the crushed natural rubber particles are discharged from the crushing box 103.

[0028] The running semiconductor refrigeration plate 9 can cool the water in the water tank 7 to turn it into cold water. The running blower 10 injects air into the spiral tube 8. When the air flows through the spiral tube 8, it can exchange heat with the cold water in the water tank 7 to reduce the air temperature. Then the air enters the crushing box 103 to accelerate the air circulation in the crushing box 103 while reducing the temperature in the crushing box 103, thereby preventing the temperature of the natural rubber from rising during the crushing process.

[0029] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
