Description

Technical Field

[0001] This utility model relates to the field of rubber reinforcing agents, and specifically to a rubber reinforcing agent grinding machine. Background Technology

[0002] Rubber reinforcing agents, as the name suggests, are mainly used to improve and reinforce the physical and chemical properties of rubber. By mixing reinforcing agents with rubber, the performance of rubber products is improved, thereby extending their service life. Different types of reinforcing agents can improve different properties of rubber. Among them, carbon black can increase the hardness, wear resistance and weather resistance of rubber, and can also significantly improve the strength, anti-aging and other properties of rubber.

[0003] A Chinese patent (CN210752859U) discloses a carbon black grinding device, comprising a mounting platform with multiple support legs evenly mounted on its bottom wall. A grinding groove is formed on the top wall of the platform, with its bottom extending to the underside of the platform. A grinding block, which rotatably engages with the grinding groove, is rotatably mounted inside the groove. A driving device is connected to the top of the grinding block. A guide plate is mounted on one side of the top of the platform, tilted and with its bottom extending into the grinding groove. A discharge plate is fixedly mounted on the bottom wall of the platform, tilted and located below the grinding groove. In this invention, the carbon black to be ground is added to the grinding groove from the top of the mounting platform, and the ground carbon black falls directly from the bottom of the platform and the grinding groove. This design is not only convenient to operate but also allows for continuous processing, greatly improving the grinding efficiency of carbon black and demonstrating a reasonable design.

[0004] The above-mentioned grinding device still has the following problems when in use: When the existing grinding device is in use, it only relies on the rotation of the grinding block to grind the carbon black raw material particles, which results in low grinding efficiency and low carbon black processing efficiency.

[0005] Therefore, it is necessary to invent a rubber reinforcing agent grinding machine to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a rubber reinforcing agent grinding machine to solve the problem mentioned in the background art that existing grinding devices rely solely on the rotation of the grinding block to grind carbon black raw material particles, resulting in low grinding efficiency and consequently low carbon black processing efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rubber reinforcing agent grinding machine, comprising a support frame, a top plate fixedly mounted on the top of the support frame via a vertical pole, a motor fixedly mounted on the top of the top plate, and a drive shaft driven by the output shaft of the motor, a grinding block fixedly mounted on the lower end of the drive shaft, a rotating block rotatably mounted inside the support frame via a staggered rotating assembly, and an annular block fixedly mounted on the outer wall of the rotating block, the annular block rotating within a pre-reserved annular groove inside the support frame.

[0008] Preferably, the top of the rotating block has an opening that is connected to the grinding chamber, so that the raw material can be added into the grinding chamber through the opening for grinding.

[0009] Preferably, the grinding block is conical in shape, and the grinding block and the grinding cavity are rotatably connected. The gap between the grinding block and the grinding cavity decreases from top to bottom, which facilitates multiple grinding processes. Finally, the carbon black powder that meets the feeding requirements is fed through the gap between the grinding cavity and the lower end of the grinding block.

[0010] Preferably, the staggered rotation assembly includes a gear one that is fixedly fitted to the outer wall of the drive shaft, and gear one and gear two are meshed together, and gear two is meshed together with a gear ring. The lower end of the gear ring is fixedly connected to the top of the rotating block through a side plate, which facilitates the staggered rotation of the drive shaft and the gear ring. At this time, the grinding block and the rotating block rotate in opposite directions, thereby enabling the grinding block and the grinding cavity to rotate in opposite directions, thus improving the grinding efficiency.

[0011] Preferably, the staggered rotation assembly further includes two circular plates fixedly connected to the top and bottom walls of gear one. Both circular plates are fixedly fitted to the drive shaft, and the outer diameter of the two circular plates is larger than the outer diameter of gear one. The gap between the two circular plates is rotatably connected to gear two. The top and bottom walls of gear two are respectively attached to the outer walls of the two circular plates and slidably connected to ensure smooth rotation of gear two.

[0012] Preferably, the inner ring of the second gear is fixedly connected to a linkage shaft, and the upper end of the linkage shaft is rotatably connected to the top plate through a bearing, which facilitates the stable rotation of the second gear.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] This invention uses a starting motor to drive the rotation of a drive shaft connected to the motor output shaft, which in turn drives the rotation of a grinding block fixedly connected to the lower end of the drive shaft. This allows the carbon black particles inside the grinding chamber to be ground. The rotation of the drive shaft drives gear one to rotate, and gear one, gear two, and a gear ring mesh with each other, causing the rotating block and the grinding block to rotate in opposite directions, thus increasing the grinding efficiency inside the grinding chamber.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-4 The rubber reinforcing agent grinding machine shown includes a support 1. A top plate 3 is fixedly installed on the top of the support 1 via a vertical rod 2. A motor 4 is fixedly installed on the top of the top plate 3. The output shaft of the motor 4 is driven by a drive shaft 5. A grinding block 6 is fixedly installed at the lower end of the drive shaft 5. A rotating block 7 is rotatably installed inside the support 1 via a staggered rotating assembly 12. An annular block 8 is fixedly installed on the outer wall of the rotating block 7. The annular block 8 rotates inside an annular groove 9 reserved inside the support 1.

[0024] During use, the motor 4 is started to drive the drive shaft 5 connected to the output shaft of the motor 4 to rotate, which in turn drives the grinding block 6 fixedly connected to the lower end of the drive shaft 5 to rotate, so that the carbon black particles inside the grinding chamber 10 are ground. Subsequently, the grinding chamber 10 and the grinding block 6 are rotated in opposite directions by the staggered rotation component 12, thereby making the grinding efficiency higher.

[0025] The grinding block 6 is cone-shaped and is rotatably connected to the grinding chamber 10. The gap between the grinding block 6 and the grinding chamber 10 decreases from top to bottom, which facilitates grinding under different specifications multiple times. The top of the rotating block 7 is pre-set with an opening 11, which is connected to the grinding chamber 10, so that the raw material can be added into the grinding chamber 10 through the opening 11 to achieve grinding.

[0026] The grinding particles are fed into the grinding chamber 10 through the opening 11. The rotation of the grinding block 6 grinds the raw material particles. Finally, the carbon black powder that meets the feeding requirements is fed through the gap between the grinding chamber 10 and the lower end of the grinding block 6.

[0027] The reverse rotation assembly 12 includes a gear 121 fixedly fitted to the outer wall of the drive shaft 5, and the gear 121 meshes with the gear 122, and the gear 122 meshes with the gear ring 123. The lower end of the gear ring 123 is fixedly connected to the top of the rotating block 7 through the side plate 124, which facilitates the reverse rotation of the drive shaft 5 and the gear ring 123, thereby enabling the grinding block 6 and the grinding cavity 10 to rotate in opposite directions, improving the grinding efficiency. The inner ring of the gear 122 is fixedly inserted with a linkage shaft 126, and the upper end of the linkage shaft 126 is rotatably connected to the top plate 3 through a bearing.

[0028] The counter-rotating assembly 12 also includes two circular plates 125 fixedly connected to the top and bottom walls of gear 121. Both circular plates 125 are fixedly fitted to the drive shaft 5, and the outer diameter of the two circular plates 125 is larger than the outer diameter of gear 121. The gap between the two circular plates 125 is rotatably connected to gear 2 122. The top and bottom walls of gear 2 122 are respectively attached to the outer walls of the two circular plates 125 and slidably connected to ensure that gear 2 122 rotates smoothly when gear 121 and gear 2 122 are meshed.

[0029] When the starting motor 4 drives the output shaft of the motor 4 to rotate, the rotation of the gear 121 fixed on the outer wall of the drive shaft 5 is simultaneously activated. The gear 121, gear 22, and gear ring 123 mesh with each other. Under the principle of gear meshing, the gear 121 and gear ring 123 rotate in different directions, causing the rotating block 7 and the grinding block 6 to rotate in different directions. This results in higher grinding efficiency inside the grinding chamber 10.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
