Description

Technical Field

[0001] This application relates to the technical field of octene copolymer particulate matter treatment devices, and more particularly to a grinding device for octene copolymer particles. Background Technology

[0002] Octene copolymers typically refer to ethylene-octene copolymer particles, which are polyolefin elastomers copolymerized from ethylene and octene under the action of a metallocene catalyst. They combine the rigidity of plastics and the elasticity of rubber. They are formed into particles through pelletizing. However, existing pelletizing processes do not treat the particle surface after pelletizing, resulting in a rough particle surface. This leads to uneven heat generation due to friction, resulting in poor melt flow and flow marks on the product surface. Furthermore, the rough surface is more likely to adsorb foreign matter, affecting the dispersion of additives during processing and causing unstable product quality and performance. Utility Model Content

[0004] The technical solution of this application is implemented as follows:

[0005] This application provides a grinding device for octene copolymer particles, including a support base, and two sets of grinding boxes and discharge boxes arranged at intervals inside the support base. The discharge boxes are inclinedly arranged on the support base and located below the grinding boxes.

[0006] The grinding box has a cavity inside, and a storage cylinder is connected inside the cavity. The storage cylinder has a receiving cavity, and one end of the receiving cavity has an opening extending to the outside of the grinding box. The storage cylinder has through holes evenly distributed.

The bottom of the turntable is connected to a connecting shaft, and the other end of the connecting shaft is connected to a first drive motor via a coupling. The first drive motor is located outside the storage tube.

[0008] The bottom of the grinding box is equipped with a discharge hopper, and the top of the discharge box is equipped with an inlet hopper. The discharge hopper is located inside the inlet hopper. The discharge box is equipped with a support plate and two sets of grinding components that are spaced apart. The grinding components include grinding rollers, and the two sets of grinding rollers form a flow area through which the material passes.

[0009] A discharge opening is provided on one side of the discharge box.

[0010] In one embodiment, the grinding component further includes a rotating shaft, one end of which is connected to the support plate via a bearing seat, and the other end of which extends to the outside of the discharge box and is fitted with a second drive motor via a coupling.

[0011] The grinding roller is mounted on a rotating shaft, and through the cooperation of the second drive motor and the rotating shaft, the grinding roller can rotate in a circular motion.

[0012] In one embodiment, the support plate is provided with a sieve hole, and the sieve hole is provided in a plurality of places and evenly distributed on the support plate.

[0020] This application discloses a grinding device for octene copolymer particles. When the particles are inverted and placed in a grinding box, they are positioned on a turntable in a storage cylinder. Since the turntable is connected to a first drive motor via a connecting shaft, when the first drive motor is started, the turntable can drive the particles to rotate circumferentially. During the rotation, the particles generate centrifugal motion and collide with each other, thereby removing the roughness on the particles and achieving a rounding operation. Furthermore, the through holes provided on the storage cylinder allow the rounded particles to pass through and enter the discharge box from the grinding box. Since the discharge box is equipped with two sets of spaced-apart grinding components, the grinding rollers in the grinding components can rotate under the cooperation of the second drive motor and the rotating shaft. The particles come into contact with the grinding rollers during the flow, thereby completing a second grinding of the particle surface. Through the cooperation of the rotating drive component and the grinding component, a dual grinding operation on the particles can be achieved, thereby solving the problem of insufficient grinding of existing particles, which leads to increased roughness and affects subsequent product processing.

[0038] Reference Figures 1-5 A grinding device for octene copolymer particles includes a support base 1, within which two sets of spaced-apart grinding boxes 2 and discharge boxes 3 are arranged. The discharge boxes 3 are inclinedly positioned on the support base 1 and located below the grinding boxes 2. This spaced-apart design enables continuous and batch processing of octene copolymer particles. The two sets of grinding boxes 2 and discharge boxes 3 can work simultaneously or alternately, significantly improving the efficiency of particle grinding and meeting the needs of large-scale production. The inclined arrangement of the discharge boxes 3, with the aid of gravity, helps the ground particles flow smoothly within the discharge boxes 3, reducing particle retention and ensuring smooth material conveying, thus improving the overall processing speed.

[0039] The grinding box 2 is provided with a cavity 21, and a storage cylinder 22 is connected inside the cavity 21. The storage cylinder 22 is provided with a receiving cavity 221. One end of the receiving cavity 221 is provided with an opening extending to the outside of the grinding box 2. The storage cylinder 22 is provided with through holes 222 evenly distributed. The through holes 222 are provided to discharge qualified particles through the through holes 222.

[0040] A rotary drive component 4 is provided inside the storage cylinder 22. The rotary drive component 4 includes a turntable 41, which is rotatably disposed inside the storage cylinder 22. The outer periphery of the turntable 41 abuts against the inner wall of the storage cylinder 22. A connecting shaft 42 is connected to the bottom of the turntable 41. The other end of the connecting shaft 42 is connected to a first drive motor 43 via a coupling. The first drive motor 43 is located outside the storage cylinder 22 and is a servo drive motor in the prior art. The first drive motor 43 provides power for the rotation of the turntable 41. The rotation of the turntable 41 drives the particles to rotate synchronously, and the rotation process achieves the rounding operation of the particles. After the rounding operation is completed, the particles enter the cavity 21 of the grinding box 2 through the through hole 222. With the cooperation of the turntable 41, the particles undergo centrifugal rotation, which can effectively correct the original irregular shape of the particles, making the shape of the particles more rounded and regular, and improving the appearance quality of the particles. After the rounding operation is completed, the particles can smoothly enter the cavity 21 of the grinding box 2 through the through hole 222.

[0041] The bottom of the grinding box 2 is equipped with a discharge hopper 23, and the discharge box 3 is equipped with an inlet hopper 31. Part of the discharge hopper 23 is located inside the inlet hopper 31. The nested design ensures that the particles discharged from the cavity 21 of the grinding box 2 can accurately enter the discharge box 3, minimizing the scattering and waste of particles during the transfer process and improving the utilization rate of materials. The discharge box 3 is equipped with a support plate 32 and two sets of spaced grinding components 5. The grinding components 5 include grinding rollers 51. The two sets of grinding rollers 51 form a flow area for material to pass through. The material flow area formed by the two sets of spaced grinding rollers 51 allows the particles to be uniformly ground when passing through the area. The rotation of the grinding rollers 51 further refines the surface of the particles, removing burrs, protrusions and other defects remaining on the surface of the particles, making the surface of the particles smoother and more delicate, and improving the overall quality of the particles. The design of two sets of grinding rollers 51 ensures that the particles are fully ground during the flow process, improving the consistency of particle quality. At the same time, continuous flow grinding further improves grinding efficiency.

[0042] A discharge opening 33 is provided on one side of the discharge box 3. The discharge opening 33 is the final output channel for the particles after grinding.

[0043] Based on the above structure, by placing the particles to be polished into the storage cylinder 22 in the polishing box 2, and since the storage cylinder 22 is equipped with a turntable 41 driven by the first drive motor 43, the particles are placed on the turntable 41. When the turntable 41 rotates in a circular motion under the cooperation of the second drive motor 53 and the rotating shaft 52, and drives the particles to rotate synchronously, the particles collide with each other under the action of centrifugal force, thereby polishing the rough protrusions of the particles and achieving a rounding effect. During the polishing process, particles that meet the requirements can enter the cavity of the polishing box 2 through the through hole 222. The particles enter the support plate 32 in the discharge box 3 through the discharge hopper 23. Due to the inclined setting of the discharge box 3, the support plate 32 can drive the particles to move towards the discharge opening 33. During the movement, the particles will pass between the two sets of grinding components 5. When the grinding roller 51 installed on the rotating shaft 52 rotates with the cooperation of the second drive motor 53, it can grind the contacted particles again. By rotating the drive component 4 and the grinding component 5, a dual grinding operation on the particles can be achieved, thereby improving the smoothness of the particle surface and solving the problem of rough surface caused by the lack of grinding of existing particles.

[0044] In one embodiment, reference is made to Figure 1 , Figure 4 and Figure 5 The grinding component 5 also includes a rotating shaft 52. One end of the rotating shaft 52 is connected to the support plate 32 via a bearing seat. This connection effectively reduces friction during the rotation of the rotating shaft 52, ensuring smooth rotation and providing stable support to prevent shaking caused by rotation from affecting the grinding accuracy. The other end of the rotating shaft 52 extends to the outside of the discharge box 3 and is equipped with a second drive motor 53 via a coupling. The second drive motor 53 is a servo drive motor as used in the prior art, and it drives the rotation of the rotating shaft 52. Power is provided by the grinding roller 51, which is mounted on the rotating shaft 52. Through the cooperation of the second drive motor 53 and the rotating shaft 52, the grinding roller 51 can rotate in a circular motion. The grinding roller 51 is mounted on the rotating shaft 52. When the second drive motor 53 is started, the grinding roller 51 can rotate in a circular motion through the transmission of the rotating shaft 52. This rotation is the key to grinding the octene copolymer particles. During the rotation, the grinding roller 51 comes into contact with the particles. Through friction and extrusion, the burrs and protrusions on the surface of the particles are ground smooth, thereby improving the quality of the particles and meeting the requirements for the smoothness of the particle surface in production.

[0045] In one embodiment, reference is made to Figure 1 and Figure 4The support plate 32 is provided with several sieve holes 321, which are evenly distributed on the support plate 32. The main function of the sieve holes 321 is to remove impurities from the particles after grinding, so as to prevent impurities from always adhering to the particles. During the grinding process, particles that do not meet the particle size requirements can fall through the sieve holes 321 and fall below the support plate 32, ensuring that the particle size discharged from the device is relatively uniform, improving the consistency of the product, and further improving the integrity of particle grinding.

[0046] In one embodiment, reference is made to Figure 1 and Figure 4 The support plate 32 is also equipped with a guide plate component 6, which includes a guide plate 61 and a side plate 62. The side plate 62 is located on the side of the guide plate 61 away from the grinding roller 51 and is inclined on the guide plate 61. The guide plate component 6 has two sets of spaced-apart guide plates 61 located between the two sets of grinding components 5, forming a material guiding area between the two sets of guide plate components 6. The function of the guide plate 61 is to guide the octene copolymer particles toward the grinding components 5, ensuring that the particles can accurately enter the grinding area and contact the grinding roller 51 for grinding. The inclined arrangement of the side plate 62 can prevent the particles from falling off the side of the guide plate 61 during the guiding process, playing a blocking and guiding role and ensuring effective material conveying. The guiding area formed by the two sets of guide plate components 6 regulates the flow path of the material, allowing the material to enter the grinding stage in an orderly manner, improving the uniformity and efficiency of grinding, and avoiding the problem of insufficient grinding caused by material accumulation or uneven distribution.

[0047] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 A slot communicating with the interior of the discharge box 3 is provided on one side of the discharge box 3. The slot is located below the support plate 32. The slot provides a convenient channel for cleaning and removing the particles and debris collected below the support plate 32. The slot is hinged to a box cover 34. The box cover 34 is hinged to the slot. When the device is working normally, the box cover 34 is in the closed state, which can prevent particles from leaking out from the slot and ensure the sealing of the device. When operation is required, the box cover 34 can be easily opened, which is convenient. This design not only ensures the stability of the device during operation, but also facilitates subsequent maintenance, cleaning and material removal, and enhances the practicality and operability of the device.

[0048] The lid 34 is provided with a handle groove 341, which provides a convenient point of force for opening and closing the lid 34. When it is necessary to operate the lid 34, the operator can put his / her fingers into the handle groove 341 to easily open or close the lid 34 without the need for other tools, which simplifies the operation process and improves work efficiency. At the same time, it makes the operation process safer and more stable, avoiding problems such as difficulty in operation or the lid 34 slipping due to the lack of a suitable point of force.

[0049] In one embodiment, reference is made to Figure 1 and Figure 3 The inner ring of the grinding box 2 is provided with an inclined end 24. One end of the inclined end 24 extends to the discharge hopper 23. The main function of the inclined end 24 is to guide the particles in the grinding box 2 to move towards the discharge hopper 23. The inclined angle of the inclined end 24 can use gravity to make these particles slide down the inclined surface to the discharge hopper 23 and then enter the subsequent discharge box 3, avoiding the accumulation of particles in the grinding box 2 and ensuring that all particles entering the grinding box 2 can smoothly enter the discharge stage.
