Description

Technical Field

[0001] This utility model relates to the field of color masterbatch processing technology, and in particular to a crusher for color masterbatch processing. Background Technology

[0002] Color masterbatch is a new type of special colorant for polymer materials, also known as pigment preparation. In the production process of color masterbatch, crushers are mainly used to crush large pieces of color masterbatch raw materials or waste materials for further processing in subsequent steps. Through crushing, the particle size of the color masterbatch can be ensured, which is beneficial to subsequent mixing, melt extrusion and other process steps.

[0003] If the existing masterbatch crusher does not stop in time when crushing masterbatch, it is easy to cause over-crushing. Over-crushing will cause the masterbatch to become ultra-fine powder. Furthermore, if the masterbatch is not evenly distributed in the crusher, some masterbatch will be over-crushed while others will not meet the crushing standard. This will not only affect the quality and efficiency of crushing production, but also increase the difficulty and cost of subsequent processing. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to solve the problem that some masterbatch is over-crushed while some masterbatch does not meet the crushing standard by setting the crushing chamber to a frustum shape that is wider at the top and narrower at the bottom.

[0005] To solve the problems of the existing technology, the technical solution of this utility model is as follows: A crusher for processing color masterbatch includes an outer body, with a feed inlet at the top and a discharge outlet at the bottom. A crushing chamber is fixedly connected to the top of the inner cavity of the outer body. The crushing chamber is shaped like a frustum, wider at the top and narrower at the bottom, to ensure that the color masterbatch always accumulates at the bottom. A rotating shaft is rotatably connected to the top of the outer body. Crushing blades are fixedly connected to the outer wall of the rotating shaft. The diameter of the crushing blades decreases from top to bottom to keep the gap between the crushing blades and the inner wall of the crushing chamber consistent. The crushing blades are composed of multiple blades, each blade having a symmetrical pair of cutting edges. All cutting edges are spirally arranged from top to bottom, which is beneficial for driving the color masterbatch downwards during the rotational cutting process. A filter plate is connected to the inner wall of the discharge outlet. The filter plate is used to separate the crushed and qualified color masterbatch. The filter plate is connected to the discharge outlet by bolts and nuts. Filter plates with different apertures can be replaced according to the processing specifications required for the color masterbatch.

[0006] Preferably, the spiral strip is fixedly connected to the inner wall of the crushing chamber, which increases the friction between the masterbatch and the crushing chamber, and helps to crush more uniformly. The spiral strip spirals downward in the direction of the crushing blade.

[0007] Preferably, the area between the crushing chamber and the outer casing is a vacuum chamber, which helps to reduce the noise generated during crushing.

[0008] Preferably, a buffer column is fixed at the bottom of the outer body. The buffer column can slide inside the support column. There is a support block at the bottom of the support column. A spring is sleeved on the outside of the buffer column and the support column. Both ends are fixedly connected to the bottom of the outer body and the top of the support block, respectively. The spring is used to buffer the vibration generated during crushing and drive the crusher to move up and down reciprocally, which enhances the effect of color masterbatch accumulating at the bottom of the crushing chamber.

[0009] Compared with the prior art, the advantages of this utility model are as follows:

[0010] This invention designs the crushing chamber as a frustum shape, wider at the top and narrower at the bottom, allowing the masterbatch to accumulate at the bottom. As the crushing blades rotate, the masterbatch is cut and crushed. During the crushing process, the spiral strips on the inner wall of the crushing chamber help to distribute and crush the masterbatch more evenly. After crushing, the masterbatch is screened by a filter plate. Only qualified masterbatch can pass through the filter plate and be discharged from the outlet, while unqualified masterbatch continues to remain in the crushing chamber for further crushing. This avoids over-crushing and improves the quality and efficiency of crushing production.

[0011] This invention helps reduce noise generation through the vacuum chamber between the crushing chamber and the outer body. At the same time, the buffer column, support column and spring can buffer the vibration generated during crushing, ensuring the stable operation of the equipment. When buffering vibration, the spring will drive the crusher to move up and down, which enhances the effect of color masterbatch accumulation at the bottom of the crushing chamber and further effectively separates the crushed and qualified color masterbatch from the uncrushed or incompletely crushed particles.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-5 A crusher for processing color masterbatch includes an outer body 1. The top of the outer body 1 has a feed inlet 2, and the bottom of the outer body 1 has a discharge outlet 3. The outer body 1 serves as the main structure of the crusher, providing protection and support. The feed inlet 2 is used to feed color masterbatch, and the discharge outlet 3 is used to discharge the crushed color masterbatch. A crushing chamber 4 is fixedly connected to the top of the inner cavity of the outer body 1 to accommodate the color masterbatch and guide it through crushing blades 6 for crushing. The crushing chamber 4 is truncated cone-shaped, wider at the top and narrower at the bottom, ensuring that the color masterbatch always accumulates at the bottom, facilitating continuous crushing. A rotating shaft 5 is rotatably connected to the top of the outer body 1. Crushing blades 6 are fixedly connected to the outer wall of the rotating shaft 5. The rotating shaft 5 is electrically connected to an external three-phase asynchronous motor, driving the crushing blades 6 to rotate and cut and crush the color masterbatch. The diameter of the crushing blades 6 decreases sequentially from top to bottom to ensure that the gap between them and the inner wall of the crushing chamber 4 remains consistent, avoiding friction between the blades and the chamber wall. The crushing blades 6 consist of multiple blades, each with a symmetrical pair of cutting edges. The blades are arranged spirally from top to bottom, which helps to drive the masterbatch downwards during the rotational cutting process while ensuring the crushing effect. The inner wall of the discharge port 3 is connected to a filter plate 7, which separates the crushed and qualified masterbatch from the uncrushed or incompletely crushed particles, ensuring that only qualified masterbatch can pass through. The filter plate 7 is connected to the discharge port by bolts and nuts, and different aperture filter plates 7 can be replaced according to the processing specifications required by the masterbatch. By setting the crushing chamber 4 into a frustum shape that is wider at the top and narrower at the bottom, the masterbatch accumulates at the bottom. As the crushing blades 6 rotate, the masterbatch is cut and crushed. During the crushing process, the spiral strips 8 on the inner wall of the crushing chamber 4 help to distribute and crush the masterbatch more evenly. After crushing, the masterbatch is screened by the filter plate 7. Only qualified masterbatch can pass through the filter plate 7 and be discharged from the discharge port 3, while unqualified masterbatch continues to remain in the crushing chamber 4 for further crushing, thereby avoiding the problem of over-crushing and improving the quality and efficiency of crushing production.

[0020] Please see Figure 4 The spiral strip 8 is fixedly connected to the inner wall of the crushing chamber 4 and is arranged in a spiral downward shape, which increases the friction between the masterbatch and the crushing chamber 4, and helps the masterbatch to be distributed and crushed more evenly in the crushing chamber 4. The spiral strip 8 spirals downward along the direction of the crushing blade 6, which helps to guide the masterbatch to gather downward.

[0021] Please see Figure 2A vacuum chamber is formed between the crushing chamber 4 and the outer body 1, which isolates the noise source, reduces the noise generated during crushing, and improves the environmental performance of the equipment.

[0022] Please see Figure 5 A buffer column 9 is fixed at the bottom of the outer body 1. The buffer column 9 can slide inside the support column 10. A support block 11 is fixedly connected to the bottom end of the support column 10. The buffer column 9 and the support column 10 provide support and buffering to reduce the impact of the vibration generated during crushing on the equipment. The spring 12 is sleeved on the outside of the buffer column 9 and the support column 10. Its two ends are fixedly connected to the bottom of the outer body 1 and the top of the support block 11, respectively. The spring 12 is used to buffer the vibration generated during crushing and drive the crusher to move up and down reciprocally, which enhances the effect of the masterbatch accumulating at the bottom of the crushing chamber 4, further buffers the vibration generated during crushing, and drives the crusher to move up and down reciprocally, which enhances the effect of the masterbatch accumulating at the bottom of the crushing chamber 4.

[0023] During operation, the operator feeds the masterbatch to be processed into the crushing chamber 4 through the top feed inlet 2. After entering the crushing chamber 4, the masterbatch accumulates at the bottom due to the chamber's frustum shape (wider at the top and narrower at the bottom). The crusher's drive unit is then activated, causing the rotating shaft 5 to rotate. The crushing blades 6, fixedly connected to the shaft 5, also rotate. The diameter of the blades 6 decreases sequentially from top to bottom, ensuring a consistent gap with the inner wall of the crushing chamber 4. As the blades rotate, the masterbatch is cut and crushed. During this process, the spiral strips 8 on the inner wall of the crushing chamber 4 increase the friction between the masterbatch and the chamber, promoting more even distribution and crushing of the masterbatch. The crushed masterbatch then... The filter plate 7 is fixed to the inner wall of the discharge port 3 and is used to separate the crushed and qualified masterbatch from the uncrushed or incompletely crushed particles. Only qualified masterbatch can pass through the filter plate 7 and be discharged from the discharge port 3, while unqualified masterbatch will continue to remain in the crushing chamber 4 for further crushing. During the crushing process, the vacuum chamber between the crushing chamber 4 and the outer body 1 helps to reduce noise generation. At the same time, the buffer column 9, the support column 10 and the spring 12 can buffer the vibration generated during crushing, ensuring the stable operation of the equipment. When buffering vibration, the spring 12 will drive the crusher to move up and down, which enhances the effect of masterbatch accumulation at the bottom of the crushing chamber 4.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
