Description

Technical Field

[0001] This utility model relates to the technical field of plastic recycling equipment, and in particular to a plastic waste recycling and processing device. Background Technology

[0002] Plastics take a long time to degrade naturally, and improperly disposed of plastic waste can persist in the environment for a long time, polluting soil, water sources, and ecosystems. Recycling plastics can reduce this pollution. Furthermore, recycling plastics reduces the demand for virgin materials, thereby reducing the environmental impact of mining and processing new materials. Compared to producing new plastics, recycling plastics reduces energy consumption and greenhouse gas emissions. In addition, the cost of recycling plastics is usually lower than the cost of producing new plastics, which can save costs for plastic manufacturers. Moreover, the plastic recycling and regeneration industry can create jobs and boost the economy. Recycled plastics can be transformed into new products, achieving resource recycling and improving resource utilization efficiency. Currently, plastic recycling typically involves crushing plastics into particles for further processing. However, existing crushing equipment often has low crushing quality, frequently resulting in some large particles in the crushed material, which affects subsequent processing.

[0003] Therefore, the existing plastic waste recycling and processing device cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a plastic waste recycling and processing device, which solves the problems mentioned in the background art by setting auxiliary components.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a plastic waste recycling and processing device, comprising an operating platform and a recycling bin set on the operating platform. The recycling bin is equipped with a crushing chamber for recycling and crushing waste plastics. The crushing chamber is equipped with a crushing component for crushing waste plastics. The bottom of the crushing chamber is equipped with an outlet for discharging the crushed waste. An auxiliary component for improving the crushing quality is provided in the crushing chamber and near the outlet. The auxiliary component includes an auger blade set at the bottom of the crushing chamber and a re-powdering channel for discharging unqualified particles. One end of the auger blade slides into the re-powdering channel. A filter plate is provided in the crushing chamber between the auger blade and the outlet. A connecting groove communicating with the outside is provided in the re-powdering channel.

[0007] Furthermore, one end of the filter plate extends slidably to the outside of the recycling bin, and a mounting protrusion is provided at the edge, with mounting bolts fixed to the recycling bin on the mounting protrusion;

[0008] Furthermore, the crushing assembly includes a feed inlet located at the upper end of the recycling bin, and a crushing rod is provided in the crushing chamber below the feed inlet. The surface of the crushing rod is provided with a plurality of crushing blades for crushing waste plastic.

[0009] Furthermore, the feed inlet has a trapezoidal cross-section, and its internal dimensions decrease sequentially from top to bottom;

[0010] Furthermore, the recycling bin is provided with a drive assembly for driving the auxiliary components and the crushing components. The drive assembly includes a drive motor fixedly mounted on the operating platform. The recycling bin is provided with several drive wheels that are respectively coaxially fixed with the crushing rod and the auger blade. The drive wheels are externally fitted with drive belts. The output end of the drive motor is fixed to any one of the drive wheels.

[0011] Furthermore, an inspection door is provided on the outside of the recycling bin and near the crushing blades;

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes a filter plate to screen plastic particles, allowing qualified particles to flow directly out of the crushing chamber through the outlet, while unqualified particles remain on the filter plate and are subsequently discharged by the auger blades for secondary crushing. This improves the crushing quality of waste plastics. Simultaneously, the rotating auger blades push aside accumulated plastic particles on the filter plate, facilitating the removal of qualified particles and preventing them from being carried into the secondary crushing channel. Furthermore, the installation protrusions and bolts allow for a detachable connection between the filter plate and the recycling bin, enabling easy replacement of the filter plate within the crushing chamber.

[0014] This invention enables the crushing of waste plastics through the design of the crushing component. The special design of the feed inlet cross-section ensures that the waste plastics entering the crushing chamber are concentrated in the middle of the crushing rod, where the shearing force is greater, thus crushing the waste plastics more thoroughly and improving the quality of plastic crushing to a certain extent.

[0015] This invention achieves synchronous movement of the crushing component and auxiliary component through the operation of the drive component, ensuring the crushing of waste plastics. In addition, the crushing blades wear down significantly during long-term crushing, which increases the probability of malfunction. Therefore, in this embodiment, an inspection door is provided outside the recycling bin and near the crushing blades so that staff can regularly inspect and maintain the crushing blades, thereby extending their service life.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1

[0026] See also Figure 1-4The following is a third embodiment of the present invention. This embodiment is a plastic waste recycling and processing device, including: an operating platform 1 and a recycling bin 2 set on the operating platform 1. The recycling bin 2 is provided with a crushing chamber 3 for recycling and crushing waste plastic. The crushing chamber 3 is provided with a crushing component 5 for crushing waste plastic. The bottom of the crushing chamber 3 is provided with an outlet for discharging the crushed waste. An auxiliary component 4 for improving the crushing quality is provided in the crushing chamber 3 and near the outlet. When using this device, the waste plastic is first put into the crushing chamber 3 in the recycling bin 2, and then crushed by the crushing component 5 set in the crushing chamber 3. After crushing, the auxiliary component 4 will screen the crushed plastic particles. If the particle size of the plastic particles is qualified, they will be discharged through the outlet at the bottom of the crushing chamber 3. The unqualified ones will be left for subsequent processing.

[0027] The auxiliary component 4 includes an auger blade 41 disposed at the bottom of the grinding chamber 3 and a re-powdering channel 42 for discharging substandard particles. One end of the auger blade 41 extends slidably into the re-powdering channel 42. A filter plate 43 is disposed in the grinding chamber 3 between the auger blade 41 and the outlet. The re-powdering channel 42 has a connecting groove that communicates with the outside. Figure 3 As shown, the filter plate 43 is located above the outlet. The plastic particles generated from the crushing of waste plastic will fall directly onto the filter plate 43. After being screened by the filter plate 43, qualified particles will flow directly out of the crushing chamber 3 through the outlet, while unqualified particles will remain on the filter plate 43. At this time, the unqualified particles remaining on the filter plate 43 can be guided into the re-powdering channel 42 by the rotation of the auger blades 41. Since the re-powdering channel 42 is provided with a connecting groove that communicates with the outside, the unqualified particles will be discharged and crushed again, thereby improving the crushing quality of waste plastic. At the same time, during the rotation of the auger blades 41, the plastic particles accumulated on the filter plate 43 will be pushed aside, making it easier for qualified particles to fall off and preventing qualified particles from being carried into the re-powdering channel 42.

[0028] One end of the filter plate 43 extends slidably to the outside of the recycling bin 2, and a mounting protrusion 44 is provided at its edge. The mounting protrusion 44 is provided with mounting bolts 45 for fixing to the recycling bin 2. During long-term use, the filter holes on the filter plate 43 may become clogged, affecting the screening efficiency. Furthermore, the acceptable diameter of the plastic particles may sometimes change. Therefore, in this embodiment, the mounting protrusion 44 and mounting bolts 45 allow for a detachable connection between the filter plate 43 and the recycling bin 2, facilitating easy replacement of the filter plate 43 in the crushing chamber 3 by the operator.

[0029] In use, the filter plate 43 can screen plastic particles, allowing qualified particles to flow directly out of the crushing chamber 3 through the outlet, while unqualified particles remain on the filter plate 43 and are then discharged by the auger blades 41 for secondary crushing, thereby improving the crushing quality of waste plastics. At the same time, as the auger blades 41 rotate, they will push aside the plastic particles accumulated on the filter plate 43, making it easier for qualified particles to fall off and preventing qualified particles from being carried into the re-powdering channel 42. In addition, the installation protrusions 44 and installation bolts 45 allow the filter plate 43 to be detachably connected to the recycling box 2, making it convenient for staff to replace the filter plate 43 in the crushing chamber 3 at any time.

[0030] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, the crushing component 5 includes a feed inlet 51 located at the upper end of the recycling bin 2. A crushing rod 52 is located in the crushing chamber 3 below the feed inlet 51. The surface of the crushing rod 52 is provided with several crushing blades 53 for crushing waste plastic. During crushing, waste plastic is fed into the crushing chamber 3 through the feed inlet 51, and then the crushing rod 52 is rotated to crush the waste plastic using the crushing blades 53.

[0031] The feed inlet 51 has a trapezoidal cross-section, with its internal dimensions decreasing sequentially from top to bottom. This special design of the feed inlet 51 concentrates the waste plastic entering the crushing chamber 3 in the middle of the crushing rod 52, where the shearing force is greater, allowing for more thorough crushing of the waste plastic and thus improving the quality of plastic crushing to a certain extent.

[0032] In use, the crushing component 5 enables the crushing of waste plastics. The special design of the cross-section of the feed inlet 51 ensures that the waste plastics entering the crushing chamber 3 are concentrated in the middle of the crushing rod 52, where the shearing force is greater, which can crush the waste plastics more thoroughly, thereby improving the quality of plastic crushing to a certain extent.

[0033] Example 3, referring to Figures 1-4This is the third embodiment of the present invention. Unlike the previous embodiment, the recycling bin 2 is externally equipped with a drive assembly 6 for driving the auxiliary assembly 4 and the crushing assembly 5. The drive assembly 6 includes a drive motor 61 fixedly mounted on the operating platform 1. The recycling bin 2 has several drive wheels 62 coaxially fixed to the crushing rods 52 and the auger blades 41, respectively. A drive belt 63 is externally sleeved on each drive wheel 62. The output end of the drive motor 61 is fixed to any one of the drive wheels 62. When the drive motor 61 runs, it drives the drive wheel 62 connected to its output end to rotate. When the drive wheel 62 rotates, it drives other corresponding drive wheels 62 to rotate via the external drive belt 63, thereby controlling the rotation of all the crushing rods 52 and the auger blades 53, realizing the movement of the crushing assembly 5 and the auxiliary assembly 4, and ensuring the crushing of waste plastics.

[0034] An inspection door 7 is provided on the outside of the recycling bin 2, near the crushing blades 53. During long-term crushing, the crushing blades 53 experience significant wear, increasing the probability of malfunction. Therefore, in this embodiment, an inspection door 7 is provided on the outside of the recycling bin 2, near the crushing blades 53, so that staff can periodically inspect and maintain the crushing blades 53, thereby extending their service life.

[0035] During use, the synchronous movement of the crushing component 5 and the auxiliary component 4 is achieved through the operation of the drive component 6, ensuring the crushing of waste plastics. In addition, the crushing blades 53 experience significant wear during long-term crushing, which increases the probability of them malfunctioning. Therefore, in this embodiment, an inspection door 7 is provided outside the recycling bin 2 and near the crushing blades 53, so that staff can regularly inspect and maintain the crushing blades 53, thereby extending their service life.

[0036] The working principle of this utility model is as follows:

[0037] When using this device, waste plastic is first placed into the crushing chamber 3 in the recycling bin 2. Then, the crushing component 5 installed in the crushing chamber 3 crushes the plastic. After crushing, the auxiliary component 4 screens the crushed plastic particles. If the particle size is within acceptable limits, it will be discharged through the outlet at the bottom of the crushing chamber 3; otherwise, it will be retained for further processing. Figure 3As shown, the filter plate 43 is located above the outlet. The plastic particles generated from the crushing of waste plastic will fall directly onto the filter plate 43. After being screened by the filter plate 43, qualified particles will flow directly out of the crushing chamber 3 through the outlet, while unqualified particles will remain on the filter plate 43. At this time, the unqualified particles remaining on the filter plate 43 can be guided into the re-powdering channel 42 by the rotation of the auger blades 41. Since the re-powdering channel 42 is provided with a connecting groove that communicates with the outside, the unqualified particles will be discharged and crushed again, thereby improving the crushing quality of waste plastic. At the same time, during the rotation of the auger blades 41, the plastic particles accumulated on the filter plate 43 will be pushed aside, making it easier for qualified particles to fall off and preventing qualified particles from being carried into the re-powdering channel 42. During long-term use, the filter holes on the filter plate 43 may become clogged, affecting the screening efficiency. Furthermore, the acceptable diameter of the plastic particles may sometimes change. Therefore, in this embodiment, the filter plate 43 is detachably connected to the recycling box 2 via the installation protrusion 44 and mounting bolt 45, facilitating easy replacement of the filter plate 43 in the crushing chamber 3 by the operator. In use, the filter plate 43 screens the plastic particles, allowing qualified particles to flow directly out of the crushing chamber 3 through the outlet, while unqualified particles remain on the filter plate 43 and are subsequently discharged by the auger blades 41 for secondary crushing, thus improving the crushing quality of waste plastics. Simultaneously, the auger blades 41, during rotation, push aside the accumulated plastic particles on the filter plate 43, allowing qualified particles to fall off and preventing them from being carried into the re-powdering channel 42. Furthermore, the installation protrusion 44 and mounting bolt 45 allow for a detachable connection between the filter plate 43 and the recycling box 2, facilitating easy replacement of the filter plate 43 in the crushing chamber 3 by the operator. During crushing, waste plastic is fed into the crushing chamber 3 through the feed inlet 51. Then, the crushing rod 52 is rotated, and the crushing blades 53 on it crush the waste plastic. The special design of the feed inlet 51's cross-section ensures that the waste plastic entering the crushing chamber 3 is concentrated in the middle of the crushing rod 52, where the shearing force is greater, resulting in more thorough crushing and thus improving the quality of plastic crushing. In use, the crushing component 5 enables the crushing of waste plastic, and the special design of the feed inlet 51's cross-section ensures that the waste plastic entering the crushing chamber 3 is concentrated in the middle of the crushing rod 52, where the shearing force is greater, resulting in more thorough crushing and thus improving the quality of plastic crushing.When the drive motor 61 runs, it drives the drive wheel 62 connected to its output end to rotate. The rotation of the drive wheel 62 drives other corresponding drive wheels 62 to rotate via the external drive belt 63, thereby controlling the rotation of all the crushing rods 52 and the auger blades 53. This achieves the movement of the crushing assembly 5 and the auxiliary assembly 4, ensuring the crushing of waste plastics. The crushing blades 53 experience significant wear during long-term crushing, increasing the probability of malfunction. Therefore, in this embodiment, an inspection door 7 is provided outside the recycling bin 2 near the crushing blades 53, allowing staff to periodically inspect and maintain the crushing blades 53, thus extending their service life. During use, the drive assembly 6 operates, achieving synchronous movement of the crushing assembly 5 and the auxiliary assembly 4, ensuring the crushing of waste plastics. Furthermore, the crushing blades 53 experience significant wear during long-term crushing, increasing the probability of malfunction. Therefore, in this embodiment, an inspection door 7 is provided outside the recycling bin 2 near the crushing blades 53, allowing staff to periodically inspect and maintain the crushing blades 53, thus extending their service life.
