Description

Technical Field

[0001] The utility model belongs to the field of polymer material crushing equipment, and particularly relates to a high-efficiency and uniform crushing assembly for polymer materials. Background Art

[0002] Polymer materials are organic compounds with high molecular weights, having unique physical and chemical properties, and are widely used in various fields.

[0003] During the processing of polymer materials, it is usually necessary to crush and grind them before subsequent processing procedures. The powders produced after the ordinary crushing equipment crushes the raw materials are of uneven thickness and not delicate enough. In the case of unsatisfactory crushing effect, the staff still needs to put the powders into the crushing equipment again for secondary crushing, resulting in low efficiency. Therefore, it is necessary to provide a high-efficiency and uniform crushing assembly for polymer materials with good crushing effect and high efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-efficiency and uniform crushing assembly for polymer materials, so as to solve the technical problems that during the processing of polymer materials, it is usually necessary to crush and grind them before subsequent processing procedures, the powders produced after the ordinary crushing equipment crushes the raw materials are of uneven thickness and not delicate enough, and in the case of unsatisfactory crushing effect, the staff still needs to put the powders into the crushing equipment again for secondary crushing, resulting in low efficiency.

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0006] A high-efficiency and uniform crushing assembly for polymer materials includes: a blade-type crushing roller group, a straight-barrel-type crushing roller group, and a rotating box body. The blade-type crushing roller group and the straight-barrel-type crushing roller group are arranged in parallel and in the same direction. The pressing gap of the blade-type crushing roller group is larger than that of the straight-barrel-type crushing roller group. In the height direction, the feeding position of the straight-barrel-type crushing roller group is arranged below the discharging position of the blade-type crushing roller group. The rotating box body surrounds the blade-type crushing roller group and the straight-barrel-type crushing roller group to form a crushing cavity. The rotating box body is fixedly provided with a blocking structure, and during the rotation of the rotating box body, the blocking structure carries the powders at the bottom of the crushing cavity to the upper part of the feeding position of the blade-type crushing roller group for release. Two roller groups with different pressing gaps realize the uniform crushing of the powders from thick to fine. The blocking structure puts the crushed powders into the pressing gap again during the rotation of the rotating box body, improving the fineness and uniformity of the produced powders.

[0007] Preferably, it further includes a base bracket, a fixed circular plate and a bearing. The fixed circular plate is fixedly connected to the base. The bearing is sleeved on the circumferential side wall of the fixed circular plate. The rotating box body is rotatably connected to the fixed circular plate through the bearing. The blade-type crushing roller group and the straight-cylinder type crushing roller group are rotatably connected to the fixed circular plate. Through such a design, the fixed circular plate and the base bracket are fixed to provide an installation position for the blade-type crushing roller group and the straight-cylinder type crushing roller group. The bearing is sleeved on the circumferential side wall of the fixed circular plate, and the rotating box body rotates through the bearing.

[0008] Preferably, the blade-type crushing roller group includes a first blade roller and a second blade roller, and the straight-cylinder type crushing roller group includes a first straight-cylinder roller and a second straight-cylinder roller. The first blade roller includes a driving end and a transmission end. The driving end extends out of one side of the crushing chamber and is in transmission connection with a driving motor. On one side located in the crushing chamber, a first output gear is fixedly arranged. A second output gear is fixedly arranged at the transmission end. The second blade roller is fixedly provided with a blade drum input gear that meshes and drives with the first output gear. One end of the first straight-cylinder roller on the same side as the transmission end is fixedly provided with a first straight-cylinder drum input gear. The first straight-cylinder drum input gear and the second output gear are in transmission cooperation through an intermediate gear. The second straight-cylinder roller is fixedly provided with a second straight-cylinder drum input gear that meshes and drives with the first straight-cylinder drum input gear. Through such a design, the advantage of the blade-type crushing roller group is that the friction force is large when the raw materials are stirred into the pressing gap, and even if there are large pieces of raw materials, they can be quickly incorporated and decomposed. The advantage of the straight-cylinder type crushing roller group is that the pressed powder is finer, but when encountering large pieces of raw materials, the raw materials will slide on the roller body above the pressing gap due to insufficient friction force. Therefore, the blade-type crushing roller group and the straight-cylinder type crushing roller group are arranged in cooperation to improve the crushing efficiency and fineness.

[0009] Preferably, the first blade roller and the second blade roller are evenly and equidistantly distributed with crushing blades, and the crushing blades of the first blade roller and the second blade roller are staggered and spliced.

[0010] Preferably, the rotating box body is a rhombohedron, and the rotating box body is provided with a window plate that can be opened and closed. A handle is fixedly arranged on the side of the window plate away from the crushing chamber. The window plate serves as a channel for adding and removing raw materials.

[0011] Preferably, the barrier structure includes a continuously arranged first plate and a second plate. The first plate and the second plate extend towards the center of gravity direction of the rotating box body, and the first plate and the second plate are arranged at an obtuse angle. Through such a design, after the raw materials are crushed, they will accumulate at the bottom of the rotating box body due to gravity. When the rotating box body rotates, the powder slides on the inner wall of the rotating box body. When the powder slides to the barrier structure, it is intercepted by the barrier structure. Since the barrier structure extends towards the center of gravity direction of the rotating box body, the powder will be driven by the barrier structure until it slides down due to gravity when it reaches the top position and falls into the feeding position of the blade type crushing roller group for crushing again.

[0012] Preferably, one piece is provided at each acute angle end of the barrier structure inside the rotating box body.

[0013] The beneficial effects of the present utility model are as follows: Two sets of roller groups with different pressing clearances achieve uniform crushing of the powder from coarse to fine. The barrier structure re-feeds the crushed powder into the pressing clearance during the rotation of the rotating box body, improving the fineness and uniformity of the produced powder.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0023] As Figures 1 to 7 shown.

[0024] Embodiment 1

[0025] A high-efficiency and uniform crushing assembly for polymer materials, comprising: a blade-type crushing rod group 1, a straight-barrel-type crushing rod group 2, and a rotating box body 3. The blade-type crushing rod group 1 and the straight-barrel-type crushing rod group 2 are arranged in parallel and in the same direction. The pressing gap of the blade-type crushing rod group 1 is greater than that of the straight-barrel-type crushing rod group 2. In the height direction, the feeding position of the straight-barrel-type crushing rod group 2 is arranged below the discharging position of the blade-type crushing rod group 1. The rotating box body 3 surrounds the blade-type crushing rod group 1 and the straight-barrel-type crushing rod group 2 to form a crushing cavity 4. The rotating box body 3 is fixedly provided with a blocking structure 5. During the rotation of the rotating box body 3, the blocking structure 5 carries the powder at the bottom of the crushing cavity 4 above the feeding position of the blade-type crushing rod group 1 and releases it.

[0026] It further includes a base bracket 6, a fixed circular plate 7, and a bearing 8. The fixed circular plate 7 is fixedly connected to the base. The bearing 8 is sleeved on the circumferential side wall of the fixed circular plate 7. The rotating box body 3 is rotationally connected to the fixed circular plate 7 through the bearing 8. The blade-type crushing rod group 1 and the straight-barrel-type crushing rod group 2 are rotationally connected to the fixed circular plate 7.

[0027] The first blade rod 9 and the second blade rod 10 are evenly and equidistantly distributed with crushing blades 21, and the crushing blades 21 of the first blade rod 9 and the second blade rod 10 are arranged in an interleaved and joined manner.

[0028] The rotating box body 3 is a rhombohedron, and the rotating box body 3 is provided with a window plate 22 that can be opened and closed. A handle 23 is fixedly arranged on the side of the window plate 22 away from the crushing cavity 4.

[0029] The implementation manner of the above embodiment is as follows: Rotate the rotating box body 3 so that the window plate 22 is directly above the blade type crushing roller group 1, and add raw materials through the window plate 22. The raw materials are first crushed by the blade type crushing roller group 1 and then fall into the straight cylinder type crushing roller group 2 for further crushing. After the straight cylinder type crushing roller group 2 finishes crushing, the powder material falls to the bottom of the crushing cavity 4. At this time, continue to rotate the crushing cavity 4, and the powder material slides on the inner wall of the rotating box body 3. When the powder material slides to the blocking structure 5, it is intercepted by the blocking structure 5. Since the blocking structure 5 extends towards the center of gravity direction of the rotating box body 3, the powder material will be driven by the blocking structure 5 until it slides down due to gravity when it is at the top position and falls into the feeding position of the blade type crushing roller group 1 for further crushing.

[0030] Embodiment 2

[0031] The blade type crushing roller group 1 includes a first blade rod 9 and a second blade rod 10. The straight cylinder type crushing roller group 2 includes a first straight cylinder rod 11 and a second straight cylinder rod 12. The first blade rod 9 includes a driving end 13 and a transmission end 14. The side of the driving end 13 extending out of the crushing cavity 4 is in transmission connection with a driving motor 15, and a first output gear 16 is fixedly arranged on the side located inside the crushing cavity 4. A second output gear 17 is fixedly arranged on the transmission end 14.

The second straight cylinder rod 12 is fixedly provided with a second straight cylinder drum input gear 20 that meshes and transmits with the first straight cylinder drum input gear 26.

[0032] The implementation manner of the above embodiment is as follows: The driving motor 15 drives the first blade roller 9 to rotate. At the same time, the first output gear 16 and the second output gear 17 fixed on the first blade roller 9 also rotate accordingly. The blade drum input gear 18 meshes with the first output gear 16 to rotate. The first straight drum input gear 26 and the second output gear 17 are meshed and rotated through the intermediate gear 19. The second straight drum input gear 20 is meshed and driven with the first straight drum input gear 26, realizing that one driving motor 15 drives all the drums of the present disclosure to rotate. The intermediate gear 19 changes the rotation directions of the first straight drum input gear 26 and the second straight drum input gear 20, making the rotation modes of the straight drum type crushing roller group 2 and the blade type crushing roller group 1 consistent.

[0033] Embodiment 3

[0034] The barrier structure 5 includes a continuously arranged first plate 24 and a second plate 25. The first plate 24 and the second plate 25 extend towards the center of gravity direction of the rotating box body 3. The first plate 24 and the second plate 25 are arranged at an obtuse angle.

[0035] One piece is provided at each acute angle end of the barrier structure 5 inside the rotating box body 3.

[0036] The implementation manner of the above embodiment is as follows: After being crushed, the raw materials will accumulate at the bottom of the rotating box body 3 due to gravity. When the rotating box body 3 rotates, the powder slides on the inner wall of the rotating box body 3. When the powder slides to the barrier structure 5, it is intercepted by the barrier structure 5. Since the barrier structure 5 extends towards the center of gravity direction of the rotating box body 3, the powder will be driven by the barrier structure 5 until it slides down due to gravity when it is at the top position and falls into the feeding position of the blade type crushing roller group 1 for crushing again.
