Description

Technical Field

[0001] This application relates to the field of plastic recycling technology, specifically a recycling device for manufacturing plastic products. Background Technology

[0002] In the plastics manufacturing industry, the recycling and disposal of waste plastic products has always been a crucial link. With the widespread use of plastic products, a large amount of waste plastic products are generated. If they cannot be effectively recycled, it will not only waste resources but also put serious pollution pressure on the environment. Traditional waste plastic product recycling methods are often quite extensive. Usually, the collected plastic products need to be transported to a special site and crushed using separate crushing equipment. This process easily generates a lot of dust and the crushing effect is inconsistent, leading to difficulties in subsequent processing. The crushed material still needs to be manually or with the help of other complex equipment to remove iron filings. Since plastic products come from a wide range of sources, they often contain metal impurities. If iron filings are not removed, they will seriously affect the quality of the plastic products after reprocessing. Moreover, dust removal is also a problem in the entire pre-processing process. Dispersed dust removal equipment is difficult to coordinate closely with crushing, iron removal and other processes, causing dust to spread freely at each stage, polluting the working environment and causing the materials to be contaminated with more impurities. In addition, the traditional recycling process involves the transfer of multiple pieces of equipment and multiple sites, which not only consumes a lot of manpower, material resources and financial resources, but also makes the recycling and processing cycle lengthy, making it difficult to meet the current urgent need for efficient and high-quality recycling of waste plastic products. Summary of the Invention

[0010] Preferably, the dust removal mechanism includes a fan and a dust collection bag, which are located on opposite sides of the recycling cylinder and are at the same horizontal level. The fan blows air into the recycling cylinder to remove dust from the broken plastic products that have passed between the fan and the dust collection bag.

[0016] Compared with the prior art, this application provides a recycling device for manufacturing plastic products, which has the following advantages:

[0017] This recycling device for plastic product manufacturing integrates crushing, iron filings removal, and dust removal into a recycling drum. After the plastic products are recycled, they can be crushed, dusted, and have iron filings removed in sequence and quickly. This avoids the transfer and waiting of materials between multiple devices and sites, greatly shortens the recycling cycle, and significantly improves the overall efficiency of waste plastic product recycling.

[0018] This recycling device for plastic product manufacturing improves material purity and ensures product quality: by performing dust removal operations in a timely manner after crushing, the fan and dust collection bag work together to effectively remove dust and impurities from the material; at the same time, the magnetic blocks in the iron filings removal mechanism accurately adsorb iron filings, and the adsorbed iron filings are scraped off and collected by the scraper, minimizing the impurity content in the material, providing a purer material basis for subsequent processing and utilization, ensuring the quality of reprocessed plastic products, and reducing the defect rate.

[0028] Please see Figures 1-2 This application provides a new technical solution: a recycling device for manufacturing plastic products, including a recycling cylinder 1, a feeding bin 2 is provided above the recycling cylinder 1 for adding plastic products to be recycled into the recycling cylinder 1, a crushing blade group 3 is provided below the discharge port of the feeding bin 2, and a vibrating plate 7 is provided below the crushing blade group 3.

[0029] One side of the vibrating plate 7 is rotatably connected to the inner wall of the recycling cylinder 1, and the other side of the vibrating plate 7 is spaced apart from the inner wall of the recycling cylinder 1. A scrap removal mechanism is provided on one side of the recycling cylinder 1. The scrap removal mechanism is located on one side of the end of the vibrating plate 7 and is used to remove scrap metal from the crushed plastic products.

[0030] A dust removal mechanism is provided between the vibrating plate 7 and the crushing blade assembly 3 to remove dust from the crushed plastic products.

[0031] In use, the plastic products to be recycled are added into the recycling cylinder 1 through the feeding bin 2. They first fall onto the crushing blade group 3 below, where the crushing blade group 3 crushes them into smaller fragments. The crushed material falls onto the vibrating plate 7, which vibrates up and down through a rotating connection between one side of its side and the inner wall of the recycling cylinder 1. During the material's transmission through the vibrating plate 7, the iron filings removal mechanism located at the end of the vibrating plate 7 removes iron filings, while the dust removal mechanism located between the vibrating plate 7 and the crushing blade group 3 removes dust, achieving preliminary purification of the crushed plastic products. Finally, the material can be discharged from the discharge valve 9 at the bottom of the recycling cylinder 1.

[0032] By integrating functional modules such as crushing, iron filings removal, and dust removal into the recycling bin, the initial integration of the waste plastic product recycling process is achieved. This allows waste plastic products to complete key pre-processing in a relatively centralized device, providing purer materials with fewer impurities for subsequent processing and utilization. This improves the efficiency of recycling and reduces the adverse effects of impurities during subsequent processing.

[0033] In some embodiments, there are two crushing blade groups 3, which rotate relative to each other inside the recycling cylinder 1 to crush the plastic products to be recycled. Driven by a motor or other power source, the blades of the two crushing blade groups 3 cooperate with each other to apply shearing force, extrusion force, etc. from different directions to the plastic products to be recycled, thereby crushing the plastic products into fragments of appropriate size, realizing the crushing function, and facilitating the smooth progress of subsequent processes.

[0034] In some embodiments, the iron filings removal mechanism includes a collection box 6, with a connection port 63 on the side of the collection box 6 that contacts the recycling cylinder 1. The collection box 6 is connected to the interior of the recycling cylinder 1, and a magnetic block 62 is rotatably connected between the collection box 6 and the recycling cylinder 1 for adsorbing iron filings from the crushed plastic products.

[0035] When in use, when the crushed plastic products are transported to the location of the iron filings removal mechanism by the vibration of the vibrating plate 7, the magnetic block 62, which is rotatably connected between the recycling cylinder 1 and the collection box 6, plays a role. Since the magnetic block is magnetic, it will attract the iron filings contained in the plastic products passing by it, so that the iron filings are attached to the surface of the magnetic block 62, thereby separating the iron filings from the plastic product material flow and achieving the purpose of removing iron filings.

[0036] In some embodiments, a scraper 61 is fixedly installed inside the collection box 6. The scraper 61 is arc-shaped, and the end of the scraper 61 contacts the outer side of the magnetic block 62 to remove iron filings adsorbed on the magnetic block 62 and allow the iron filings to fall into the collection box 6.

[0037] During use, as the magnetic block 62 continuously attracts iron filings, the iron filings accumulate on the surface of the magnetic block 62. At this time, the arc-shaped scraper 61 fixed inside the collection box 6 comes into play. Since the end of the scraper 61 is in contact with the outside of the magnetic block 62, the scraper 61 will scrape off the iron filings attracted on the surface of the magnetic block 62 under the rotation of the magnetic block 62, so that the iron filings fall into the collection box 6 along the scraper 61 for collection, which is convenient for subsequent centralized processing of iron filings and impurities.

[0038] In some embodiments, the dust removal mechanism includes a fan 5 and a dust collection bag 8. The fan 5 and the dust collection bag 8 are located on opposite sides of the recycling cylinder 1, and the fan 5 and the dust collection bag 8 are at the same horizontal position. The fan 5 is used to blow air into the recycling cylinder 1 to remove dust from the broken plastic products that have passed between the fan 5 and the dust collection bag 8. The dust that has been blown away falls into the dust collection bag 8.

[0039] When in use, the fan 5 starts working and blows air into the recycling bin 1. When the broken plastic products pass between the fan 5 and the dust collection bag 8, the airflow will blow the dust attached to the plastic products, causing the dust to separate from the plastic products under the action of the airflow. Then, guided by the airflow, the dust enters the dust collection bag 8 through the connecting pipe 81 and is collected, thus achieving the purpose of removing dust.

[0040] In some embodiments, the dust collection bag 8 is connected to the inside of the recycling cylinder 1 via a connecting pipe 81. A filter screen 82 is provided at the end of the connecting pipe 81 that is connected to the recycling cylinder 1 to prevent broken plastic products from entering the dust collection bag 8.

[0041] In some embodiments, the vibrating plate 7 is inclined toward the collection box 6. The vibrating plate 7 is rotatably connected to one side of the recycling cylinder 1 via a rotating block 71. A cam 72 is provided below the vibrating plate 7. The cam 72 rotates under the drive of a motor to make the vibrating plate 7 rotate up and down around the rotating block 71, vibrating the crushed plastic products on the vibrating plate 7 and accelerating the dust dissipation. Under the drive of the motor, the cam 72 starts to rotate. Since the cam 72 is in contact with the vibrating plate 7, the rotation of the cam 72 will periodically lift or lower the vibrating plate 7, causing the vibrating plate 7 to rotate up and down around the rotating block 71, thereby producing a vibration effect. Under the vibration, the dust and other impurities mixed in with the crushed plastic products placed on the vibrating plate 7 are more easily dispersed, which is convenient for subsequent dust removal and other operations, and also facilitates the material to be transported to the scrap removal mechanism and other directions.

[0042] In some embodiments, a guide plate 4 is provided above the interval between the vibrating plate 7 and the recovery cylinder 1. The guide plate 4 is inclined downwards to guide the plastic products after being crushed by the crushing blade assembly 3.

[0043] In some embodiments, a cover plate 21 is provided above the feeding bin 2; when it is not necessary to add the plastic products to be recycled into the feeding bin 2, the cover plate 21 is covered, and the cover plate 21 can block the upper opening of the feeding bin 2 to prevent external debris (such as dust, other foreign objects, etc.) from entering the feeding bin 2 and mixing into the plastic products to be recycled, thus ensuring the purity of the material added into the recycling cylinder 1.

[0044] In some embodiments, a discharge valve 9 is provided at the bottom of the recycling cylinder 1; the processed plastic material flows out of the recycling cylinder 1 through the discharge valve 9 under the action of gravity, so as to discharge the material for subsequent collection, transfer and further processing and utilization.

[0045] In the operation of a recycling device for manufacturing plastic products, firstly, the cover plate 21 above the feeding hopper 2 is opened, and the plastic products to be recycled are fed into the recycling cylinder 1 through the feeding hopper 2. The plastic products to be recycled into the recycling cylinder 1 fall to the crushing blade group 3 below. Driven by a motor, the blades of the two crushing blade groups 3 cooperate with each other, applying shearing force, extrusion force, etc. from different directions to crush the plastic products into smaller fragments. The plastic products crushed by the crushing blade group 3 fall downwards under the action of gravity. The guide plate 4 is inclined downwards to guide the crushed plastic products to slide accurately onto the vibrating plate 7 in a set direction. After the material falls onto the vibrating plate 7, driven by a motor, the vibrating plate 7 rotates up and down around the rotating block 71, thereby generating a vibration effect. Under the vibration, dust and other impurities mixed in with the plastic products are more easily dispersed. At the same time, the dust removal mechanism located between the vibrating plate 7 and the crushing blade group 3 starts to work, and the fan 5 blows air into the recycling cylinder 1. Internal airflow separates dust from plastic products after crushing by the airflow between fan 5 and dust bag 8. The dust is then guided by the airflow and collected inside dust bag 8 via connecting pipe 81. As vibrating plate 7 vibrates, the material is gradually transported to its end. When it reaches the iron filings removal mechanism, the magnetic block 62, rotatably connected between collection box 6 and recycling cylinder 1, acts to adhere iron filings to its surface, thus separating them from the plastic product material flow. As the magnetic block 62 continuously attracts iron filings, the arc-shaped scraper 61 fixed inside collection box 6 comes into play. The end of scraper 61 contacts the outer side of magnetic block 62. With the rotation of magnetic block 62 or the movement of related components, scraper 61 scrapes off the iron filings adsorbed on the surface of magnetic block 62, causing them to fall into collection box 6 for collection and subsequent centralized processing. After a series of processes including crushing, vibration dust removal, and iron filings removal, the plastic product material finally passes through recycling cylinder 1. The discharge valve 9 at the bottom discharges the material from the recovery cylinder 1.
