Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a plastic crusher. Background Art

[0002] Plastic shredding can convert waste plastics into small particles, which can be reused as raw materials, reducing the demand for fresh raw materials and promoting the recycling of resources.

[0003] Traditional crushers crush plastics through the relative movement of two hard metal disks. Such relatively arranged crushers are often suitable for crushing large plastics into relatively small blocks, but cannot crush them into small particles.

[0004] A Chinese patent discloses a high-speed crusher with a dust reduction function, with the patent number CN216678404U. By setting a crushing mechanism and using the cooperation of a crushing shell and a crusher, the motor drives the crushing rod to rotate inside the crushing groove, thus effectively crushing materials at high speed. However, during actual use, there is a gap between the crushing rod and the crushing groove. During the high-speed rotation of the motor, some rotational forces will be generated, causing some plastics to move (upward) in the gap away from the crushing rod along the rotational force, resulting in poor crushing effect and low efficiency of the crushing mechanism.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] According to one aspect of the present utility model, an embodiment of the present utility model provides a plastic crusher, including:

[0042] A housing, formed with a crushing chamber and a discharge port communicating with the crushing chamber;

[0043] A driving motor, disposed on the housing;

[0044] A crushing rod, one end of which is disposed at the output end of the driving motor and the other end of which is disposed in the crushing chamber;

[0045] A grinding member, disposed on the inner wall of the crushing chamber, the grinding member having a abutting surface, and the abutting surface being inclined in a direction close to the discharge port.

[0046] In this embodiment, the driving motor is started to rotate the crushing rod, and the grinding edge on the crushing rod interacts with the abutting surface of the grinding member to effectively crush the plastic material entering the crushing chamber. The crushed plastic particles naturally move towards the discharge port due to the inclined design of the grinding member, realizing continuous and efficient crushing and material conveying.

[0047] By the combined use of the grinding member and the crushing rod, a more uniform crushed material can be obtained, improving the quality of the final product.

[0048] The rotation of the crushing rod and the fixed abutting surface of the grinding member form a crushing structure that combines static and dynamic elements, enabling the plastic material to be effectively crushed into small particles within the crushing chamber. The abutting surface of the crushing rod and the grinding member is combined to achieve efficient cutting, tearing, and grinding of the material.

[0049] Please refer to Figures 1 - 6 , an embodiment of the present utility model provides a plastic crusher 100, including:

[0050] A housing 110, forming a crushing chamber 110a and a discharge port 110b communicating with the crushing chamber 110a;

[0051] A driving motor 120, provided on the housing 110;

[0052] A crushing rod 130, one end provided at the output end of the driving motor 120 and the other end provided within the crushing chamber 110a;

[0053] A grinding member 140, provided on the inner wall of the crushing chamber 110a. The grinding member 140 has an abutting surface 140a, and the abutting surface 140a is inclined in a direction approaching the discharge port 110b.

[0054] In this embodiment, the driving motor 120 is started to rotate the crushing rod 130. The grinding edge on the crushing rod 130 interacts with the abutting surface 140a of the grinding member 140, effectively crushing the plastic material entering the crushing chamber 110a. Due to the inclined design of the grinding member 140, the crushed plastic particles naturally move towards the discharge port 110b, achieving continuous and efficient crushing and material conveyance.

[0055] By the combined use of the grinding member 140 and the crushing rod 130, a more uniform crushed material can be obtained, improving the quality of the final product.

[0056] The rotation of the crushing rod 130 and the fixed abutting surface 140a of the grinding member 140 form a crushing structure that combines static and dynamic elements, enabling the plastic material to be effectively crushed into small particles within the crushing chamber 110a. The abutting surface 140a of the crushing rod 130 and the grinding member 140 is combined to achieve efficient cutting, tearing, and grinding of the material.

[0057] It should be noted that the housing 110 is in the shape of a rectangular box; the crushing chamber 110a is a conical cavity; the discharge port 110b is a circular through-hole, and the grinding member 140 is generally trapezoidal in shape.

[0058] The crushing chamber 110a is the core working area of the plastic crusher 100, providing a closed space for more efficient crushing of the plastic material.

[0059] The crushing rod 130 is located within the crushing chamber 110a, and one end thereof is connected to the output end of the drive motor 120. When the motor operates, the crushing rod 130 rotates accordingly, and the plastic material is crushed by the grinding edges (primary grinding edge 131 and secondary grinding edge 141) thereon.

[0060] The general shape of the crushing rod 130 is conical.

[0061] The grinding member 140 is fixed to the inner wall of the crushing chamber 110a and has a bearing surface 140a with a specific inclination angle. It not only plays an auxiliary role in crushing, but also promotes the movement of the crushed material towards the discharge port 110b through the inclined design of its bearing surface 140a, improving the crushing efficiency and the material conveying efficiency.

[0062] In at least one embodiment of the present application, the angle between the bearing surface and the discharge port 110b is α, satisfying the relationship: 60° ≤ α ≤ 75°.

[0063] Please refer to Figures 1 - 6 , in this embodiment, when the drive motor 120 is started, the crushing rod 130 begins to rotate, and the plastic material is crushed within the crushing chamber 110a under the combined action of the grinding edges on the crushing rod 130 and the bearing surface 140a of the grinding member 140.

[0064] Under the action of the bearing surface 140a, the crushed plastic particles move towards the discharge port 110b along the set angle α.

[0065] By precisely setting the angle between the bearing surface and the discharge port 110b between 60° and 75°, it can be ensured that the crushed material is not only effectively crushed but also efficiently pushed towards the discharge port 110b.

[0066] This helps to reduce material blockage during the crushing process, ensuring the continuous operation and high output rate of the crusher.

[0067] This helps to achieve a more uniform crushing effect because the material will be more dispersed during the movement, reducing the uneven crushing phenomenon caused by material accumulation.

[0068] If the angle α exceeds 75°, although the material will still move towards the discharge port 110b, due to the excessive angle, the moving speed of the material towards the discharge port 110b under the combined action of gravity and centrifugal force will slow down, which will lead to a reduction in the conveying efficiency.

[0069] An excessive angle may cause the material to stay in the crushing chamber 110a for too long, especially for those light or fine materials that are prone to accumulation, increasing the risk of blockage.

[0070] If the included angle α is less than 60°, the material will move too quickly towards the discharge port 110b without being sufficiently pulverized, which will result in poor pulverization effect, and the final product may contain large uncrushed plastic blocks.

[0071] In at least one embodiment of the present application, the abutting surface is located on a side close to the discharge port 110b.

[0072] Please refer to Figures 1 - 6 , in this embodiment, the abutting surface is located on a side close to the discharge port 110b, reducing the ineffective circulation of the material in the pulverizing chamber 110a. The material is directly guided near the discharge port 110b for final pulverization, thereby improving the overall pulverization efficiency.

[0073] In at least one embodiment of the present application, the grinding member 140 has a secondary grinding edge 141, and the inclination direction of the secondary grinding edge 141 is arranged along the rotation direction of the grinding rod 130.

[0074] In at least one embodiment of the present application, a plurality of the secondary grinding edges 141 are provided on a single grinding member 140, and a relief groove 141a is formed between two adjacent secondary grinding edges 141.

[0075] Please refer to Figures 1 - 6 , in this embodiment, when the drive motor 120 is started, the grinding rod 130 begins to rotate. The material is first roughly pulverized by the main grinding edge on the grinding rod 130.

[0076] The material then enters the action range of the secondary grinding edge 141, and the secondary grinding edge 141 with an inclination direction consistent with the rotation direction of the grinding rod 130 provides an additional and more delicate pulverizing effect.

[0077] After being pulverized by the secondary grinding edge 141, the material moves smoothly through the relief groove 141a, avoiding blockage or excessive aggregation between the grinding members 140, thereby maintaining the continuity and efficiency of the pulverization process.

[0078] Through the fine action of the secondary grinding edge 141, a more efficient and more uniform pulverization effect can be achieved, improving the quality of the finally pulverized material.

[0079] The relief groove 141a helps to reduce the blockage phenomenon of the material between the grinding members 140, ensuring the continuous operation and stability of the pulverizer.

[0080] The secondary grinding edge 141 is an additional grinding edge provided on the grinding member 140. It is used to provide a more delicate pulverizing effect and enhance the pulverization effect.

[0081] The inclination direction of the secondary grinding edge 141 is consistent with the rotation direction of the crushing rod 130, which helps the material move smoothly along the rotation direction of the crushing rod 130 during the crushing process and improves the crushing efficiency.

[0082] A plurality of secondary grinding edges 141 are provided on a single grinding member 140, and a relief groove 141a is formed between two adjacent secondary grinding edges 141, which improves the fineness and uniformity of crushing. At the same time, the relief groove 141a helps to reduce the blockage and aggregation of materials.

[0083] The secondary grinding edge 141 is an inclined cutting edge.

[0084] In at least one embodiment of the present application, there are a plurality of the grinding members 140, and the plurality of grinding members 140 are arranged on the inner wall of the crushing chamber 110a at equal angles with the axis of the discharge port 110b as the axis.

[0085] Please refer to Figures 1 - 6 , in this embodiment, when plastic materials are put into the crushing chamber 110a, they are first subjected to the preliminary crushing effect of the main grinding edges on the crushing rod 130.

[0086] As the materials move further and the crushing rod 130 rotates, the materials are further finely crushed by a plurality of grinding members 140 distributed at equal angles.

[0087] The crushed materials leave the crushing chamber 110a through the discharge port 110b. At this time, the materials have been evenly crushed to improve the crushing efficiency.

[0088] The equal-angle arrangement of the plurality of grinding members 140 ensures the uniform distribution of the crushing effect in the crushing chamber 110a, thereby achieving the uniform crushing of the materials and improving the crushing quality and efficiency.

[0089] Since the materials can evenly contact the grinding members 140 throughout the crushing process, the possibility of the materials not being fully crushed is reduced, thereby improving the overall crushing efficiency.

[0090] The layout of the evenly distributed grinding members 140 helps the smooth flow of materials in the crushing chamber 110a, reducing equipment downtime and maintenance requirements caused by material blockage.

[0091] In at least one embodiment of the present application, the outer peripheral surface of the crushing rod 130 is provided with a primary grinding edge 131, the primary grinding edge 131 includes a first cutting edge portion 1311 and a second cutting edge portion 1312, and the inclination directions of the first cutting edge portion 1311 and the second cutting edge portion 1312 are opposite.

[0092] In at least one embodiment of the present application, a connecting blade 1313 is formed between the first blade portion 1311 and the second blade portion 1312, and the first blade portion 1311 extends obliquely from the connecting blade 1313 towards the axis of the crushing rod 130.

[0093] Please refer to Figures 1 - 6 , in this embodiment, when the crushing rod 130 rotates driven by the motor, the primary grinding blade 131 starts to contact and crush the input plastic material.

[0094] Since the inclination directions of the first blade portion 1311 and the second blade portion 1312 are opposite, the material will be subjected to cutting forces in two directions when passing through the primary grinding blade 131. Such a two-way cutting effect effectively improves the fineness and efficiency of crushing.

[0095] When the material passes through the connecting blade 1313, the inclined design of the first blade portion 1311 enables the material to be subjected to more uniform and continuous cutting forces when moving towards the axis direction of the crushing rod 130, further enhancing the crushing effect.

[0096] By adopting the blade design with two-way inclination, the material can be cut and crushed more effectively, thereby improving the crushing efficiency.

[0097] The primary grinding blade 131 consists of two different parts, namely the first blade portion 1311 and the second blade portion 1312, and the inclination directions of these two parts are opposite. The two blade portions can provide cutting forces in different directions when crushing the material, improving the crushing efficiency and effect.

[0098] There is a connecting blade 1313 between the first blade portion 1311 and the second blade portion 1312, and the first blade portion 1311 starts from the connecting blade 1313 and extends obliquely towards the axis of the crushing rod 130. It provides a smooth transition and enhanced cutting force, contributing to the effective crushing of the material.

[0099] It should be noted that the primary grinding blade 131 is spiral and is arranged along the outer peripheral surface of the crushing rod 130.

[0100] In at least one embodiment of the present application, one end of the housing 110 close to the drive motor 120 is provided with a feed inlet 110c, and the feed inlet 110c communicates with the crushing chamber 110a.

[0101] In at least one embodiment of the present application, the plastic crusher 100 further includes:

[0102] A filter screen 150, detachably connected to the housing 110, and the filter screen 150 is arranged at the discharge port 110b;

[0103] The material receiving part 160 is arranged on the side of the filter screen 150 away from the housing 110. The material receiving part 160 forms a material receiving cavity 160a, and the material receiving cavity 160a is communicated with the discharge port 110b through the filter screen 150.

[0104] Please refer to Figures 1 - 6 , in this embodiment, the plastic material to be pulverized is put into the pulverizing cavity 110a through the feed port 110c located at one end of the housing 110 close to the driving motor 120.

[0105] The driving motor 120 drives the pulverizing rod 130 to rotate, and the material is pulverized by the grinding edges on the pulverizing rod 130.

[0106] The pulverized material enters the filter screen 150 through the discharge port 110b. The filter screen 150 screens out larger particles that do not meet the particle size requirements, and only fine particles that meet the requirements can pass through.

[0107] The material screened by the filter screen 150 enters the material receiving cavity 160a of the material receiving part 160, completing the collection process of the pulverized material.

[0108] The filter screen 150 ensures that only materials that meet specific particle size requirements can pass through, improving the quality of the pulverized material.

[0109] The material receiving part 160 facilitates the collection of the screened pulverized material, facilitates the subsequent processing or transportation of the material, and improves the operation efficiency.

[0110] It should be noted that the filter screen 150 is slidably connected to the housing 110, the material receiving part 160 is slidably connected to the filter screen 150, sliding grooves are provided on both sides of the filter screen 150, slide rails are provided on the housing 110, and slide rails are provided on the side of the material receiving part 160 close to the filter screen 150.

[0111] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
