Description

Technical Field

[0001] This utility model relates to the field of crushing devices, specifically a crushing device for plastic materials. Background Technology

[0002] In the production process of plastic products, it is sometimes necessary to further crush plastic granules into finer powders to meet specific production process requirements, such as for manufacturing high-precision injection molded products and plastic films. Finer plastic powders can improve the quality and performance of products. By rotating two or more toothed rollers relative to each other, the plastic material is squeezed and torn, breaking it into smaller particles. This is suitable for recycling and processing block or sheet-like plastic waste. When the moving blades of the crusher are severely worn, the blades become dull, and iron filings are easily generated during cutting, contaminating the plastic material.

[0003] A search revealed a Chinese patent with authorization number CN212524395U, which discloses a plastic crusher. The crusher includes a base plate with a support rod on its upper surface. The support rod is fixedly connected to a fixed box. A motor plate is fixedly connected to the left side wall of the fixed box, and two sets of motors are fixedly connected to the upper surface of the motor plate. The output end of each motor is rotatably connected to the left end of a first rotating shaft, and the right end of the first rotating shaft passes through the fixed box and is fixedly connected to the left end of a shredding blade. In this plastic crusher, material is fed into the fixed box through the feed inlet. Powering the motor causes the first rotating shaft to drive the shredding blade to crush the material. The crushed material falls through a discharge pipe onto a screen plate. Through the cooperation of a fixed column and a spring, the screen plate operates, filtering out plastic particles that fall into a material box, while metal particles remain on the screen plate and are discharged through an impurity box. This reduces metal impurities in the plastic particles, thereby improving the purity of the plastic.

[0004] The aforementioned plastic crusher has the following shortcomings: the inner wall of the sieve plate is made of magnetic material. When the plastic passes through the sieve plate, the iron filings inside the plastic are attracted by the magnet inside the sieve plate under the vibration of the device. After the iron filings stick to the outer wall of the sieve plate, they cannot continue to move on the outer wall of the sieve plate due to the action of the magnet. At this time, as the device continues to attract them, the iron filings will accumulate on the sieve plate and cannot be cleaned. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a plastic material crushing device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic material crushing device, comprising a plastic crushing device and a sieve plate, wherein the sieve plate is fixedly installed on the outer wall of the plastic crushing device, a buffer column is fixedly installed on the outer wall of the sieve plate, and a screening groove is opened inside the sieve plate, and a support block corresponding to the screening groove is fixedly installed on the outer wall of the sieve plate, a magnetic block is fixedly installed at the end of the support block, and a collection box is slidably installed on the outer wall of the magnetic block, and a limit block is fixedly installed on the outer wall of the collection box, a connecting strip is fixedly installed at the end of the collection box, an elastic element is fixedly installed on the outer wall of the connecting strip, and a limiting block is fixedly installed at the end of the elastic element, and a locking block corresponding to the limiting block is fixedly installed on the outer wall of the support block.

[0007] By adopting the above technical solution, iron filings can enter the collection box more smoothly under the restriction of the buffer column. At the same time, the collection box can be more stable in the plastic crushing device under the restriction of the elastic element, the limiting block and the locking block. The simultaneous pull-out design of multiple sets of collection boxes and the non-magnetic material design of the collection boxes make it easier to clean the collection boxes when they leave the plastic crushing device, which further improves the practicality of the device.

[0008] Furthermore, the buffer column has a semi-circular cross-section, and multiple sets of buffer columns are installed at equal intervals on the outer wall of the sieve plate.

[0009] By adopting the above technical solution, it is ensured that the iron filings in the plastic scrap can be more fully screened through the setting of the buffer column.

[0010] Furthermore, the inner wall of the screening trough near the plastic crushing device is designed to be inclined, and multiple sets of screening troughs are arranged at equal intervals within the screen plate.

[0011] By adopting the above technical solution, it is ensured that plastic scraps can smoothly pass through the screening tank and enter the collection box under the restriction of multiple sets of buffer columns.

[0012] Furthermore, the support block is located on the outer wall of the sieve plate away from the buffer column, and two sets of support blocks are symmetrically arranged on the outer wall of the sieve plate.

[0013] By adopting the above technical solution, it is ensured that the collection box can be smoothly matched with the screening trough inside the sieve plate.

[0014] Furthermore, the support block has a groove corresponding to the limiting block, and the magnetic block is located at the end of the support block away from the sieve plate.

[0015] By adopting the above technical solution, it is ensured that the magnetic block can better attract and confine iron filings.

[0016] Furthermore, the ends of the multiple sets of collection boxes are all fixedly connected to the outer wall of the connecting strip, and two sets of locking blocks are symmetrically arranged on the outer wall of the collection box, and the collection box is designed with non-magnetic material.

[0017] By adopting the above technical solution, it is ensured that the iron filings inside the collection box can be cleaned up smoothly.

[0018] Furthermore, the cross-section of the limiting block is a semi-circular structure, and the cross-section of the locking block is also a semi-circular structure.

[0019] By adopting the above technical solution, it is ensured that the restriction block and the lock block can better restrict each other.

[0020] Compared with the prior art, the present invention provides a plastic material crushing device, which has the following beneficial effects:

[0021] 1. A plastic material crushing device, comprising a buffer column, a screening trough, a support block, a magnetic block, and a collection box, wherein, under the multiple constraints of the collection box, the crushed plastic material is smoothly guided by the screening trough and, under the vibration of the plastic crushing device itself, the iron filings are attracted by the magnetic block and smoothly separated from the plastic fragments. At the same time, under the continuous vibration of the device, the plastic fragments move smoothly out of the device. Through the separation of iron filings, the purity of the plastic material is improved, thereby improving the quality and performance of plastic products.

[0022] 2. A plastic material crushing device, which, by setting a limit block, a connecting strip, an elastic element, a limiting block and a locking block, allows iron filings in the collection box to be smoothly removed through the setting of the connecting strip, and at the same time, under the restriction of the elastic element, the limiting block and the locking block, further ensures the stability of the collection box in the plastic crushing device.

At the same time, under the restriction of the elastic element, the limiting block and the locking block, the collection box can be more stable in the plastic crushing device. Through the simultaneous pull-out design of multiple sets of collection boxes and the non-magnetic material design of the collection boxes, the collection boxes can be cleaned more smoothly when leaving the plastic crushing device, further improving the practicality of the device.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] A plastic material crushing device, such as Figure 1 - Figure 5 As shown, the device includes a plastic crushing device 1 and a sieve plate 2. The sieve plate 2 is fixedly installed on the outer wall of the plastic crushing device 1. A buffer column 21 is fixedly installed on the outer wall of the sieve plate 2, and a screening groove 22 is opened inside the sieve plate 2. A support block 3 corresponding to the screening groove 22 is fixedly installed on the outer wall of the sieve plate 2. A magnetic block 4 is fixedly installed at the end of the support block 3, and a collection box 5 is slidably installed on the outer wall of the magnetic block 4. Under the restriction of the buffer column 21, the plastic scraps first fall into the collection box 5. Under the continuous vibration of the plastic crushing device 1, the iron filings in the plastic scraps are trapped by the attraction of the magnetic block 4. The iron filings remain in the collection box 5. The connecting strip 6 is reinstalled on the outer wall of the screen plate 2 through the engagement of the limiting block 51 and the support block 3. The limiting block 51 is fixedly installed on the outer wall of the collection box 5. The connecting strip 6 is fixedly installed at the end of the collection box 5. The elastic element 7 is fixedly installed on the outer wall of the connecting strip 6. The limiting block 71 is fixedly installed at the end of the elastic element 7. The locking block 8 corresponding to the limiting block 71 is fixedly installed on the outer wall of the support block 3. When the connecting strip 6 is pushed, the locking block 8 begins to restrict the limiting block 71 at the end of the elastic element 7 under the setting of the elastic element 7.

[0033] Please see Figure 2 - Figure 4 The buffer column 21 has a semi-circular cross-section and multiple sets of buffer columns 21 are installed at equal intervals on the outer wall of the screen plate 2. Under the restriction of multiple sets of buffer columns 21, the plastic scraps can be screened more fully in the screen plate 2, ensuring that the iron filings in the plastic scraps can be screened more fully through the setting of buffer columns 21.

[0034] Please see Figure 3 and Figure 3The inner wall of the screening tank 22 near the plastic crushing device 1 is inclined. Guided by the screening tank 22, the plastic scraps smoothly enter the collection box 5. The screening tank 22 is set with multiple sets at equal intervals in the screen plate 2 to ensure that the plastic scraps can smoothly pass through the screening tank 22 and enter the collection box 5 under the restriction of multiple sets of buffer columns 21.

[0035] Please see Figure 2 and Figure 4 The support block 3 is located on the outer wall of the sieve plate 2 away from the buffer column 21, and two sets of support blocks 3 are symmetrically arranged on the outer wall of the sieve plate 2. Under the guidance of the two sets of support blocks 3, it is ensured that the collection box 5 can smoothly fit into the screening groove 22 in the sieve plate 2.

[0036] Please see Figure 2 The support block 3 has a groove corresponding to the limiting block 51. By setting the groove corresponding to the limiting block 51, the collection box 5 can slide better in the support block 3. The magnetic block 4 is located at the end of the support block 3 away from the screen plate 2, ensuring that the magnetic block 4 can better attract and restrict the iron filings.

[0037] Please see Figure 2 Figure 5 Multiple sets of collection boxes 5 are fixedly connected to the outer wall of the connecting strip 6 at their ends. By moving the connecting strip 6, multiple sets of collection boxes 5 can be moved at the same time. Two sets of locking blocks 8 are symmetrically arranged on the outer wall of the collection box 5. The two sets of locking blocks 8 can better restrict the position of the collection box 5. The collection box 5 is designed with non-magnetic material. When the user removes the collection box 5, there is no magnetism of the magnetic block 4, ensuring that the iron filings in the collection box 5 can be cleaned smoothly.

[0038] Please see Figure 4 and Figure 5 The limiting block 71 has a semi-circular cross-section, and the locking block 8 has a semi-circular cross-section. When the outer wall of the limiting block 71 is in contact with the outer wall of the locking block 8, the self-generated stress of the elastic element 7 ensures that the limiting block 71 and the locking block 8 can better restrict each other.

[0039] The working principle of this utility model is as follows: When the plastic crushing device 1 is started, the crushed plastic material moves out of the plastic crushing device 1 through the sieve plate 2. At this time, the plastic scraps fall into the collection box 5 first under the restriction of the buffer column 21. Under the continuous vibration of the plastic crushing device 1, the iron filings in the plastic scraps are restricted by the attraction of the magnetic block 4 and the iron filings stay in the collection box 5. At the same time, the plastic scraps move out of the collection box 5 under the vibration of the device. With the restriction of multiple sets of collection boxes 5, the content of iron filings in the plastic scraps is reduced, and finally the plastic scraps are moved out of the plastic crushing device 1.

[0040] When the user needs to clean the collection box 5, by pulling the connecting strip 6, the limiting block 71 at the end of the elastic element 7 slides on the outer wall of the locking block 8. Eventually, the limiting block 71 is no longer restricted by the locking block 8. At this time, the user can further pull the locking block 8 until the collection box 5 is completely separated from the magnetic block 4. At this time, without the attraction of the magnetic block 4, the iron filings in the collection box 5 can be cleaned smoothly. Then, the user can reinstall the connecting strip 6 on the outer wall of the sieve plate 2 through the engagement relationship between the limiting block 51 and the support block 3. At the same time, as the user continues to push the connecting strip 6, when the outer wall of the limiting block 71 is in contact with the outer wall of the locking block 8, as the user further pushes the connecting strip 6, under the setting of the elastic element 7, the locking block 8 begins to restrict the limiting block 71 at the end of the elastic element 7, making the collection box 5 more stable on the outer wall of the sieve plate 2.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
