Description

Technical Field

[0001] This invention relates to the field of plastic waste recycling technology, specifically to a device for recycling and reusing plastic slitting edge materials. Background Technology

[0002] Recycling and reusing plastic slitting scraps is a crucial step in the plastics processing industry to achieve resource recycling, reduce production costs, and practice environmental protection. On production lines for films, sheets, and other plastic products, the slitting process generates a large amount of scrap. To facilitate subsequent cleaning, melting, and granulation, these scraps typically need to be crushed into uniformly sized fragments or granules. However, during the generation, conveying, and crushing of these scraps, various impurities are easily introduced, with fine metal particles being the most dangerous. If these metal impurities are not removed, they will not only damage core equipment such as extruder screws and dies during subsequent high-temperature melting, causing high maintenance costs and production interruptions, but they will also act as catalysts to accelerate the thermal degradation of plastics, leading to a decline in the performance of recycled materials and affecting the quality and safety of the final product.

[0003] To address this issue, existing technologies typically incorporate magnetic separation devices after the crushing equipment, utilizing magnetic force to adsorb and separate ferromagnetic metal particles from the material. Common magnetic separation structures include permanent magnet drums, magnetic frames, or tubular magnetic rods. These devices can remove most ferrous impurities to a certain extent. However, in actual operation, especially when processing large quantities of continuously fed edge material, a significant technical drawback exists: when metal particles are adsorbed onto the surface of the magnetic separation structure, they gradually accumulate and form "metal bridges" or "blockage layers." This blockage not only covers the magnetic area, significantly reducing subsequent magnetic separation efficiency and causing some metal particles to escape into downstream processes, but more seriously, continuous blockage hinders the normal flow of the crushed plastic material, causing material channel blockage and forcing the entire recycling system to shut down for cleaning, severely impacting production continuity and efficiency.

[0004] Currently, the clogging problem in magnetic separators mainly relies on manual, periodic shutdowns for cleaning. This method not only increases the labor intensity of operators, interrupts the production process, and reduces the automation level and operating efficiency of the equipment, but also makes it difficult to accurately determine the timing of cleaning, often only discovering the blockage when it is severe, by which time it has already had a real impact on production. In addition, during manual cleaning, operators directly contact strongly magnetic components and metal debris, posing certain safety risks.

[0005] Therefore, the magnetic separation stage in existing plastic slitting edge recycling equipment urgently needs to solve two interrelated technical problems: First, how to efficiently and continuously remove fine metal particles mixed in with plastic materials after crushing to ensure the purity of recycled materials; second, and more importantly, how to automatically and promptly collect the magnetically separated metals when the magnetic separation structure tends to become blocked or initially blocked due to metal adsorption, and simultaneously clear the magnetic separation channels to restore the smooth flow of materials, thereby ensuring the continuous, stable, and efficient operation of the entire recycling system and avoiding downtime and efficiency loss caused by manual intervention.

[0006] Therefore, there is a need for equipment for recycling and reusing plastic slitting scraps to solve the above problems. Summary of the Invention

[0007] To address the aforementioned problems, namely the difficulty of existing plastic waste crushing devices in continuously removing fine metal particles from materials and the inability to promptly clear blockages in the magnetic separation structure, this invention provides a plastic slitting edge recycling and reuse device.

[0008] A plastic shavings recycling device includes a crusher, a conveyor belt, and a storage tank. The discharge end of the conveyor belt is located at the inlet of the crusher. A hopper is provided at the bottom of the crusher. The inlet of the storage tank is in fluid communication with the bottom of the hopper. An intermediate plate is provided inside the hopper, and a through hole is provided through the intermediate plate. Magnetic plates are provided on both sides of the through hole. A push plate is slidably installed at one end of the through hole, and a storage bag is connected to the other end of the through hole. A sensor is provided inside the hopper, located below the intermediate plate. By providing an intermediate plate with a through hole inside the hopper and magnetic plates on the sides of the through hole, the crushed plastic... As the material passes through the through-hole, fine metal particles are attracted by the magnetic plate, enabling the device to efficiently and continuously remove fine metal particles from crushed plastic, ensuring the purity of the recycled material. A pusher plate slides across one end of the through-hole, and a storage bag is connected to the other end. When the magnetic plate attracts too much metal, causing blockage or obstruction, the pusher plate slides to push the attracted metal into the storage bag, clearing the through-hole. A sensor located below the intermediate plate sends a signal to an external controller when the through-hole is blocked or obstructed. The external controller then controls the pusher plate to slide. This configuration allows the device to collect the magnetically separated metal in a timely and automatic manner and clear the through-hole.

[0009] Preferably, a second support is provided at the bottom of the crusher, the feed inlet of the crusher is located at the top, the conveyor belt is set inside the conveying frame via a transmission roller, a guide plate is fixedly installed at the top of the conveying frame, the outer end of the guide plate is located directly above the feed inlet of the crusher, a first support is fixedly installed at the top of the bottom of the conveying frame, a motor is fixedly installed on one side of the conveying frame, the output shaft of the motor is coaxially fixedly connected to one of the transmission rollers via a coupling, a feeding frame is connected to the bottom of the conveying frame, the bottom of the conveyor belt is located inside the feeding frame, and a baffle is fixedly installed on the outer surface of the conveyor belt. By setting up the conveyor belt, it is convenient to fill the crusher with material, the conveying frame and the feeding frame can prevent the material on the conveyor belt from falling off the side, the baffle can prevent the material from sliding down, and the guide plate can ensure that the material falls accurately into the crusher.

[0010] Preferably, a support plate is rotatably mounted on the top of the outer end of the feeding frame via a hinge shaft. Multiple abutment grooves are formed on the lower surface of the support plate. An abutment plate is hinged to the outer end of the feeding frame near the bottom via a first torsion spring shaft. The end of the abutment plate away from the first torsion spring shaft abuts against the abutment groove. By rotatably mounting the support plate on the outer end of the feeding frame, when feeding material into the feeding frame, simply lay the container containing the material on the support plate to allow the material to fall into the feeding frame. If it is necessary to change the angle of the container so that the opening of the container is angled downwards to facilitate material sliding, simply rotate the support plate upwards. The abutment plate will automatically rotate under the action of the first torsion spring shaft and abut against the corresponding abutment groove to prevent the support plate from rotating downwards, thus facilitating operation.

[0011] Preferably, a connecting seat is provided at the bottom of the hopper, and an air supply pipe and a conveying pipe are respectively connected to the two ends of the connecting seat. The end of the air supply pipe away from the connecting seat is connected to the air outlet of the high-pressure blower, and the end of the conveying pipe away from the connecting seat is connected to the interior of the storage tank near the top. A third support is provided on the side of the storage tank near the bottom. The high-pressure blower sends airflow through the air supply pipe and the connecting seat into the conveying pipe, thereby blowing the material in the hopper into the conveying pipe and then conveying it into the storage tank.

[0012] Preferably, an inclined guide plate is fixedly installed on the upper surface of the transverse hole in the connecting seat. The guide plate is inclined downward from one end near the air supply pipe to the other end near the conveying pipe. By setting the guide plate, the high-speed airflow is directly blown into the conveying pipe, which can effectively prevent the airflow from flowing into the hopper.

[0013] Preferably, the intermediate plate has a plurality of through holes vertically extending through it, and every two adjacent through holes are connected by a connecting hole. The two push plates in every two adjacent through holes are connected by a connecting plate, and the connecting plate slides in the connecting hole.

[0014] Preferably, an inlet hole is provided through one side of the hopper, and an outlet hole is provided through the other side of the hopper. The inlet hole and the outlet hole are respectively connected to the two ends of the through hole. A lifting rod is fixedly installed on the side of the hopper near the inlet hole. An electric telescopic rod is fixedly installed at the bottom end of the lifting rod. The telescopic end of the electric telescopic rod extends into the inlet hole and is fixedly connected to one of the push plates. The storage bag is fixedly installed on the side of the hopper near the outlet hole. The storage bag is connected to the outlet hole. A second hinge plate is hinged to the top of the outlet hole through a second torsion spring shaft. After the sensor transmits the blocking signal to the external controller, the external controller controls the electric telescopic rod to push the push plate to slide. When the push plate passes through the outlet hole, the second hinge plate will abut against the upper surface of the push plate. When the electric telescopic rod pulls the push plate back, the second hinge plate will push the metal on the push plate into the storage bag. The second hinge plate can effectively prevent the metal in the storage bag from flowing back.

[0015] Preferably, two first hinge plates are symmetrically mounted on both sides of the inner surface of the hopper via two second torsion springs. Both first hinge plates are inclined downwards from the outside to the inside, and the inner ends of the two first hinge plates abut against each other. The sensors are provided on the inner sides of both first hinge plates. When the through hole is not blocked, the inner ends of the two first hinge plates do not abut against each other under the action of airflow and falling material. When the through hole is blocked, the inner ends of the two first hinge plates abut against each other, and the two sensors sense each other and transmit the blocking signal to the external controller.

[0016] The beneficial effects of this invention are as follows: 1. This invention features an intermediate plate with through holes inside the hopper and a magnetic plate on the side of the through holes. When the crushed plastic passes through the through holes, the fine metal particles are attracted by the magnetic plate, thus enabling the device to efficiently and continuously remove fine metal particles from the crushed plastic and ensure the purity of the recycled material.

[0017] 2. This invention features a pusher plate that slides at one end of the through hole and a storage bag connected to the other end. When the magnetic plate attracts too much metal, causing blockage or obstruction of the through hole, the pusher plate can be slid to push the attracted metal into the storage bag, thus clearing the through hole. A sensor is installed below the middle plate. When the through hole is blocked or obstructed, the sensor transmits a signal to an external controller, which then controls the pusher plate to slide. This design enables the device to collect the magnetically separated metal in a timely and automatic manner and clear the through hole.

[0018] 3. This invention features a pallet mounted on the outer end of the feeding frame. When feeding material into the feeding frame, simply place the box containing the material onto the pallet, and the material inside the box will be scooped into the feeding frame. If it is necessary to change the angle of the box so that the opening of the box is angled downward to facilitate the sliding of the material, simply rotate the pallet upward. The abutment plate will automatically rotate under the action of the first torsion spring shaft and abut into the corresponding abutment groove to prevent the pallet from rotating downward, which is convenient for operation.
