Description

Technical Field

[0001] This utility model relates to the field of rubber breaking machine technology, specifically a crusher with low-temperature crushing function. Background Technology

[0002] A rubber shredder is a mechanical device used for crushing waste rubber and breaking down reclaimed rubber. It can peel off the outer layer of rubber from tires for further processing and utilization.

[0003] Common tire shredders on the market generate a lot of heat during the tire shredding process. Tire rubber blocks are prone to carbonization in high-temperature environments, reducing the recycling rate of rubber. Based on our company's many years of production experience and customer feedback, our technical department has developed corresponding optimization solutions to reduce the heat generated by the shredder during production.

[0004] Therefore, we propose a crusher with low-temperature crushing function. Summary of the Invention

[0005] The purpose of this invention is to provide a crusher with a low-temperature crushing function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crusher with a low-temperature crushing function, comprising a base plate, two rotating rollers mounted on the upper surface of the base plate, and extrusion rollers mounted on the outer surfaces of the two rotating rollers; a cooling component mounted above the base plate, used to control the temperature of the extrusion roller surface, which can prevent damage to the rubber block caused by the high temperature generated by the extrusion rollers during operation; and a transmission component mounted in front of the upper surface of the base plate, used to provide power for the extrusion operation of the two extrusion rollers.

[0007] Preferably, the cooling assembly includes four connecting pipes, each of which is fixedly connected to a rotating roller. A sealing cap is fitted onto the end of each connecting pipe furthest from the extrusion roller. Water inlet pipes are fixedly connected to the left side of the two sealing caps on the left side, and water outlet pipes are fixedly connected to the right side of the two sealing caps on the right side. A water storage tank is fixedly installed on the rear part of the upper surface of the base plate. First water pumps are placed on the upper surface of the base plate from left to right. The water inlet pipes are fixedly connected to the water storage tanks via the first water pumps, and the water outlet pipes are fixedly connected to the water storage tanks via second water pumps.

[0008] Preferably, each of the rotating rollers has a first fixing plate rotatably connected to both sides of its outer surface, and the bottom surface of each first fixing plate is fixedly connected to the upper surface of the base plate, with all four first fixing plates at the same horizontal height.

[0009] Preferably, each of the closed caps has an annular groove on its inner wall, and each of the connecting pipes has an annular block that matches the annular groove fixedly connected to its outer surface.

[0010] Preferably, a second fixing plate is fixedly connected to the outer surface of each of the closed covers, and the bottom end of each second fixing plate is fixedly connected to the upper surface of the base plate.

[0011] Preferably, the transmission assembly includes a second gear, which has two sets. Each set of the second gear is fixedly connected to the outer surface of the same rotating roller, and the two sets of the second gear mesh with each other. A drive motor is fixedly installed in front of the upper surface of the base plate, and the output shaft of the drive motor is fixedly connected to a first gear. The first gear meshes with the corresponding second gear.

[0012] Preferably, all four second gears are at the same horizontal level.

[0013] Preferably, the four second fixing plates are at the same horizontal height.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When waste rubber needs to be crushed, it is first placed between two compression rollers. The opposing rotation of the rollers crushes the rubber towards the center. Then, the power switches for the first and second water pumps are activated. The first pump draws water from the storage tank into the rotating rollers through the inlet pipe. The water inside the rotating rollers is then pumped back into the storage tank by the second pump through the outlet pipe. Because the rotating and compression rollers are made of materials with good thermal conductivity, and water has a high specific heat capacity, the water carries away a significant amount of heat as it flows through the rollers, thus lowering the temperature. This closed-loop system of water flow inside the rollers and external water source allows for heat absorption within the rollers and release of heat within the storage tank, enabling water recycling.

[0016] By setting up a cooling component, the rotation roller and the extrusion roller can work together to effectively prevent high temperatures on the surface of the extrusion roller from causing carbonization of the rubber during the crushing of waste rubber, thus further improving production efficiency.

[0017] 2. When the extrusion roller is rotating and crushing, simply turn on the power switch that is electrically connected to the drive motor. When the output shaft of the drive motor rotates, the first gear will rotate synchronously, which in turn will cause the second gear meshing with the first gear to rotate. Then, the two sets of meshing second gears will drive the entire rotating roller to rotate, thereby driving the extrusion roller to rotate and crush.

[0018] By setting up a transmission component, the two extrusion rollers are changed from the traditional opposing extrusion transmission to gear transmission. The purpose of this is to more flexibly control the speed difference between the two rotating rollers. This greatly reduces the heat from the extrusion rollers during the rubber crushing process, thereby lowering the material temperature and producing higher quality rubber granules.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] Example 1: A crusher with low-temperature crushing function includes a base plate 3, two rotating rollers 5 mounted on the upper surface of the base plate 3, and extrusion rollers 16 mounted on the outer surface of each of the two rotating rollers 5. A cooling component 1 is mounted above the base plate 3 and is used to control the surface temperature of the extrusion rollers 16. The cooling component 1 can prevent damage to the rubber block caused by the high temperature generated by the extrusion rollers 16 during operation. A transmission component 2 is mounted in front of the upper surface of the base plate 3 and is used to provide power for the extrusion operation of the two extrusion rollers 16.

[0028] The cooling component 1 includes four connecting pipes 6, each of which is fixedly connected to the rotating roller 5. Each connecting pipe 6 has a sealing cover 7 sleeved on the end away from the squeezing roller 16. The left side of the two sealing covers 7 on the left side is fixedly connected to the water inlet pipe 12, and the right side of the two sealing covers 7 on the right side is fixedly connected to the water outlet pipe 14. A water storage tank 15 is fixedly installed on the rear part of the upper surface of the base plate 3. A first water pump 11 is placed on the upper surface of the base plate 3 from left to right. The water inlet pipe 12 is fixedly connected to the water storage tank 15 through the first water pump 11, and the water outlet pipe 14 is fixedly connected to the water storage tank 15 through the second water pump 13.

[0029] Each rotating roller 5 has a first fixing plate 4 rotatably connected to both sides of its outer surface. The bottom surface of each first fixing plate 4 is fixedly connected to the upper surface of the base plate 3. All four first fixing plates 4 are at the same horizontal height and are used to support the rotating roller 5 as a whole.

[0030] Each sealing cover 7 has an annular groove 8 on its inner wall, and each connecting pipe 6 has an annular block 9 that matches the annular groove 8 fixedly connected to its outer surface. This can prevent the sealing cover 7 from obstructing the rotation of the connecting pipe 6 and the rotating roller 5.

[0031] Each closed cover 7 has a second fixing plate 10 fixedly connected to its outer surface, and the bottom end of each second fixing plate 10 is fixedly connected to the upper surface of the base plate 3.

[0032] When waste rubber needs to be crushed, it is first placed between two compression rollers 16. The opposing rotation of the two compression rollers 16 crushes the waste rubber towards the center of the rollers. At this time, the power switches for the first water pump 11 and the second water pump 13 are activated. The first water pump 11 pumps water from the storage tank 15 into the rotating roller 5 through the inlet pipe 12. The water entering the rotating roller 5 is then pumped back into the storage tank 15 by the second water pump 13 in conjunction with the outlet pipe 14. Because the rotating roller 5 and the compression rollers 16 are made of materials with good thermal conductivity, and water has a high specific heat capacity, the water carries away a large amount of heat as it flows through the rotating roller 5, thus lowering the temperature. The water flow inside the rotating roller 5 and the external water source form a closed loop. Heat is absorbed inside the rotating roller 5 and released inside the storage tank 15, allowing the water to be recycled.

[0033] By setting up the cooling component 1, the cooperation between the rotating roller 5 and the extrusion roller 16 in crushing waste rubber can effectively prevent the rubber from carbonizing due to high temperature on the surface of the extrusion roller 16, thus further improving production efficiency.

[0034] In embodiment 2, the transmission component 2 includes a second gear 19, which has two sets. Each set of second gears 19 is fixedly connected to the outer surface of the same rotating roller 5. The two sets of second gears 19 mesh with each other. A drive motor 17 is fixedly installed in front of the upper surface of the base plate 3. The output shaft of the drive motor 17 is fixedly connected to a first gear 18, which meshes with the corresponding second gear 19.

[0035] All four second gears 19 are at the same horizontal level.

[0036] The four second fixing plates 10 are at the same horizontal height.

[0037] When the extrusion roller 16 is rotating and crushing, simply turn on the power switch that is electrically connected to the drive motor 17. When the output shaft of the drive motor 17 rotates, the first gear 18 can rotate synchronously, which in turn can make the second gear 19 meshing with the first gear 18 rotate. Then, the two sets of meshing second gears 19 can drive the rotating roller 5 to rotate as a whole, which in turn drives the extrusion roller 16 to rotate and crush.

[0038] In Example 3, other structures remain unchanged. By adjusting the first water pump 11 and the second water pump 13, the inlet pipe 12 and the outlet pipe 14 can be swapped, allowing the inlet and outlet water inlets to be adjusted arbitrarily in the direction of water inlet and outlet, thereby enabling the switching function of water inlet operation or water outlet operation on one side.

[0039] By setting the transmission component 2, the two extrusion rollers 16 are changed from the traditional extrusion transmission to gear transmission. The purpose of this is to more flexibly control the speed difference between the two rotating rollers 5. In this way, the heat from the crushing of rubber by the extrusion rollers 16 is greatly reduced during the crushing process, thereby reducing the material temperature and producing higher quality rubber granules.

[0040] In Example 4, other structures remain unchanged, except that the pipe inlets are connected in parallel, the cold water inlet uses a large-diameter pipe, and the hot water return uses a small-diameter pipe. This ensures that the surfaces of the two extrusion rollers 16 maintain a certain temperature when operating at low temperatures, resulting in better crushing effect. The processing technology is similar to the tire dry powder crushing method, which generally refers to crushing waste rubber by shearing and extrusion forces from rollers or other crushing equipment at a processing temperature of 50±5℃ or slightly higher.
