Description

Technical Field

[0001] This invention relates to the field of plastic recycling technology, specifically to a plastic dismantling equipment for waste electronic products. Background Technology

[0002] With the rapid development of technology and the improvement of economic level, the pace of electronic product upgrading is accelerating, and the amount of waste electronic products is also increasing year by year. These waste products contain many valuable resources, such as glass, plastic, and metal. During dismantling, some materials need to be put into a crusher to be crushed into small pieces, and then transported by a conveyor to subsequent sorting equipment such as air separators and magnetic separators to facilitate the recycling of plastics.

[0003] The existing patent application, with publication number CN106985308A and publication date of July 28, 2017, is titled "An Environmentally Friendly Waste Plastic Processing System for Electronic Products." This patent includes a base plate, a frame device located above the base plate, a crushing device housed within the frame device, a heating device, a baffle device located below the crushing device, a support device located above the baffle device, and a motor device located below the baffle device. This environmentally friendly waste plastic processing system for electronic products can simultaneously crush and heat the plastic from electronic products, softening it and protecting the crushing teeth. It also improves crushing efficiency and facilitates the collection and centralized processing of the crushed plastic. It is labor-intensive and simple to use.

[0004] The above application has shortcomings. The traditional crushing chamber is fixed and cannot penetrate the material accumulation layer when heating plastic, resulting in local overheating. There is a lot of residual moisture on the surface of the plastic, which causes adhesion and clumping. If a screen is installed to screen the crushed plastic, the plastic fragments are easy to block the screen holes, especially after the plastic is heated. Therefore, it is necessary to stop the machine frequently for cleaning to avoid clogging the channel. Summary of the Invention

[0005] The purpose of this invention is to provide a plastic dismantling equipment for waste electronic products to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A plastic dismantling device for waste electronic products includes a frame and a feeding channel fixedly connected to one side of the top of the frame. A crushing chamber and a drying discharge chamber are installed and connected at the top of the feeding channel. A limiting screen basin inserted into the feeding channel is movably installed at the bottom of the crushing chamber. A driving component is installed on the other side of the top of the frame. A telescopic cutter shaft that passes through the drying discharge chamber and enters the crushing chamber is connected to the end of the driving component. A guide ring that abuts against the telescopic cutter shaft and a material-scraping frame that extends into the feeding channel are installed in the drying discharge chamber. When the telescopic cutter shaft rotates, it drives the drying discharge chamber to move horizontally back and forth, thereby pushing the limiting screen basin to move up and down back and forth, and forcing the material-scraping frame to scrape the material in the feeding channel back and forth.

[0008] Preferably, a feed hopper is installed on the top of the crushing chamber, and a pair of dustproof covers are hinged inside the feed hopper.

[0009] Preferably, the crushing chamber is slidably connected to the feeding channel, and a feed inlet adapted to the limiting screen basin is opened on one side of the top of the feeding channel, and the limiting screen basin and the feed inlet are inserted into each other.

[0010] Preferably, the telescopic cutter shaft includes a transmission sleeve connected to the driving component, a shaft is inserted in the transmission sleeve, a crushing cutter is installed in the crushing chamber on the shaft, and a pressing rod is installed on the transmission sleeve, the pressing rod abutting against the guide ring.

[0011] Preferably, one side of the feeding rack is hinged to the drying and feeding hopper, and the other side is rotatably connected to a counterweight rotating rod. Multiple feeding wheels are installed on the counterweight rotating rod. The bottom of the inner wall of the feeding channel is inclined, and the bottom of the feeding wheels rests on the inclined surface inside the feeding channel.

[0012] Preferably, the feeding channel is equipped with an abutting component, one end of which abuts against the drying discharge hopper, and the other end of which abuts against the inclined limiting screen basin.

[0013] Preferably, the abutting component includes a push-pull frame slidably installed in the feeding channel, an abutting rod extending out of the feeding channel is fixedly connected to one side of the push-pull frame, and a wedge-shaped top block is symmetrically fixedly connected to the other side, and a wedge-shaped abutting block that abuts and cooperates with each wedge-shaped top block is symmetrically fixedly connected to the bottom of the limiting screen basin.

[0014] Preferably, a heating element is installed inside the drying discharge hopper, a fan blade is rotatably installed on one side of the inner wall of the drying discharge hopper, the transmission sleeve is coaxially connected to the fan blade, and a reset top spring is symmetrically installed between the drying discharge hopper and the feeding channel.

[0015] Preferably, a lifting protrusion is fixedly connected to the top of the wedge-shaped top block, and a handle is installed on the top of the abutment rod. When the lifting protrusion abuts against the wedge-shaped abutment block, the limiting screen basin is raised above the feed inlet.

[0016] Preferably, a storage box is installed inside the frame, and the top of the storage box has a receiving interface located below the drying discharge hopper. A maintenance receiving hopper is rotatably hinged to one side of the storage box.

[0017] In the above technical solution, by setting a telescopic cutter shaft that runs through the drying chamber and the crushing chamber, the drying chamber is moved horizontally when driven to rotate by the drive component. Combined with the lifting and lowering of the limiting screen basin, a dynamic feeding space is formed, which increases the screening speed of the crushed plastic. The reciprocating movement of the drying chamber allows heat radiation to evenly cover the plastic fragments, reducing the amount of residual moisture on the surface of the fragments and reducing the problem of material sticking together. The feeding rack is driven by the displacement of the drying chamber to scrape the feeding channel. Its reciprocating stroke generates an inertial excitation force of acceleration, which eliminates the phenomenon of material bridging and breaks up the clumps of plastic in the feeding channel, improving the drying effect while preventing the channel from being blocked.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0032] Please see Figure 1-8This invention provides a waste electronic product plastic dismantling device, including a frame 1 and a feeding channel 2, which is fixedly connected to one side of the top of the frame 1. A crushing chamber 3 and a drying and unloading chamber 4 are installed and connected to the top of the feeding channel 2. The feeding channel 2 is a rectangular cross-section pipe used to receive the waste plastics crushed by the crushing chamber 3 and then feed them into the drying and unloading chamber 4. A limiting screen basin 301, which is inserted into the feeding channel 2, is movably installed at the bottom of the crushing chamber 3. The limiting screen basin 301 is a basin-shaped screen with a specific screen hole size, and the edge of the screen basin is slidably connected to the inner wall of the crushing chamber 3. It can reciprocate vertically. The crushed material must be screened through this screen before entering the feeding channel 2 below. The drive unit 5 is installed on the other side of the top of the frame 1. The end of the drive unit 5 is connected to a telescopic cutter shaft 6 that passes through the drying feed bin 4 and enters the crushing bin 3. The drying feed bin 4 is equipped with a guide ring 401 that abuts against the telescopic cutter shaft 6 and a material feeding frame 402 that extends into the feeding channel 2. When the telescopic cutter shaft 6 rotates, it drives the drying feed bin 4 to move horizontally back and forth to push the limiting screen basin 301 to reciprocate up and down, and forces the material feeding frame 402 to scrape the material in the feeding channel 2 back and forth.

[0033] Specifically, when the drive component 5 drives the telescopic cutter shaft 6 to rotate, the telescopic cutter shaft 6 directly acts on the guide ring 401. Through the abutting cooperation between the guide ring 401 and the telescopic cutter shaft 6, the entire drying feeding bin 4 is driven to move horizontally reciprocally along the length of the feeding channel 2. The blades on the telescopic cutter shaft 6 located in the crushing bin 3 rotate accordingly, forcefully dismantling and impacting the waste electronic plastics fed from the top of the crushing bin 3. After crushing, plastic fragments smaller than the screen hole size fall into the feeding channel 2 through the screen holes of the bottom limiting screen basin 301. While the telescopic cutter shaft 6 rotates, its special structure acts on the guide ring 401, driving the drying feeding bin 4 to move horizontally reciprocally. Then, this horizontal movement is transmitted to the limiting screen basin 301, forcing the limiting screen basin 301 to continuously rise and fall. The screen basin moves down, widening the feeding gap and accelerating the discharge of qualified crushed fragments. The screen basin moves up and resets, while simultaneously agitating large-sized materials or incompletely crushed materials remaining on the screen basin to prevent them from clogging the screen holes and lifting excessively large particles back to the crushing area. The screen basin undergoes secondary crushing, and the periodic lifting and lowering of the screen basin creates a dynamic feeding space, greatly improving screening efficiency and the discharge speed of crushed materials. This avoids the clogging problem of traditional fixed screen plates. After the screened fragments enter the feeding channel 2, they are within the heat source range of the drying feeding hopper 4. The horizontal reciprocating movement of the drying feeding hopper 4 brings multiple drying advantages. The moving drying feeding hopper 4 dynamically changes the area covered by heat radiation or hot air, ensuring that plastic fragments in different positions can receive uniform and comprehensive heating. The slight vibration generated by the movement of the hopper is transmitted to the fragment layer, causing the fragments to roll and shift, greatly reducing the dead zones of heat, improving drying efficiency, and making the moisture evaporate more thoroughly, significantly reducing the residual moisture content on the surface of the fragments. At the same time, the material rack 402 reciprocates and scrapes in the feeding channel 2, removing wet fragments adhering to the channel wall or bottom. It uses vibration force to loosen and disperse the wet plastic blocks that have begun to stick together in the channel, effectively reducing the problem of mutual adhesion caused by moisture, creating good conditions for subsequent recycling.

[0034] Compared with the prior art, the embodiments of the present invention, by setting a telescopic cutter shaft 6 that runs through the drying chamber and the crushing chamber 3, pushes the drying chamber to move horizontally when driven by the drive component 5 to rotate. In addition, the lifting and lowering of the limiting screen basin 301 forms a dynamic feeding space, which improves the screening speed of the crushed plastic. The reciprocating movement of the drying chamber makes the heat radiation evenly cover the plastic fragments, reducing the residual moisture on the surface of the fragments and reducing the problem of material sticking together. The material feeding rack 402 is driven by the displacement of the drying chamber to scrape the feeding channel 2. Its reciprocating stroke generates an inertial excitation force of acceleration, which eliminates the phenomenon of material bridging and breaks up the plastic clumps in the feeding channel 2, improving the drying effect while preventing the channel from being blocked.

[0035] In a further embodiment of the present invention, a feed hopper 302 is installed on the top of the crushing chamber 3, and a pair of dustproof covers 303 are hinged inside the feed hopper 302. Specifically, when the high-speed rotating blades in the crushing chamber 3 shear the material, a large amount of dust and fragments are generated and splashed. The dustproof covers 303 remain in a normally closed state during the material feeding gap, forming a physical isolation layer for the crushing chamber, preventing dust from spreading to the working environment, significantly improving the working environment and meeting industrial hygiene standards, while also enhancing the heat flow guidance efficiency of the drying system in the feeding channel 2 of the drying hopper 4.

[0036] In a further embodiment of the present invention, the crushing chamber 3 is slidably connected to the feeding channel 2. The feeding channel 2 has horizontally opened grooves on both sides. The inner walls of the crushing chamber 3 are fixedly connected to the sliding blocks that match the grooves. The top side of the feeding channel 2 has an inlet 201 that matches the limiting screen basin 301. The limiting screen basin 301 and the inlet 201 are interlocked. Specifically, when the crushing chamber 3 is reciprocating up and down, the bottom of the limiting screen basin 301 always moves up and down within the inlet 201. Due to the presence of the limiting screen basin 301, the crushing chamber 3 will not easily deviate in the horizontal direction, ensuring stability during operation. However, if it is necessary to inspect and maintain the cutter and telescopic cutter shaft 6 in the crushing chamber 3, the limiting state of the crushing chamber 3 can be released by further raising the limiting screen basin 301, allowing the crushing chamber 3 to slide out along the feeding channel 2, exposing the bottom of the crushing chamber 3, which is convenient for workers to operate quickly.

[0037] In a further embodiment of the present invention, the telescopic cutter shaft 6 includes a transmission sleeve 601 connected to a drive component 5. The drive component 5 is a drive motor, and the output shaft of the drive motor and the transmission sleeve 601 are connected by a coupling. A shaft 602 is inserted into the transmission sleeve 601, and the shaft 602 is inserted into the inner hole of the transmission sleeve 601. It is circumferentially locked by a flat key and can slide axially. A crushing blade 603 is installed on the shaft 602 inside the crushing chamber 3. A pressing rod 604 is installed on the transmission sleeve 601. A groove 407 is opened on the guide ring 401, and the pressing rod 604 abuts against the guide ring 401. Stationary blades that cooperate with the crushing blade 603 are installed on both sides of the inner wall of the crushing chamber 3. The drive component 5 drives the transmission sleeve 601 to rotate, and through the transmission sleeve 601 drives the shaft 602 to rotate synchronously, causing the moving crusher 603 to rotate at high speed in the crushing chamber 3. The material enters the shearing zone formed by the moving crusher 603 and the stationary blade to achieve crushing. Since the shaft 602 can move axially in the transmission sleeve 601, the crushing chamber 3 can be smoothly pulled out to facilitate the removal of the crushing chamber 3 for inspection and maintenance. When the pressure rod 604 rotates from the groove 407 in the guide ring 401 to other positions, the drying discharge bin 4 gradually moves towards the crushing chamber 3. When the pressure rod 604 rotates back into the groove 407, the drying discharge bin 4 will reset and move back to achieve reciprocating motion.

[0038] In a further embodiment of the present invention, one side of the material feeding frame 402 is hinged to the drying discharge bin 4, and the other side is rotatably connected to a counterweight rotating rod 403. Multiple material feeding wheels 404 are installed on the counterweight rotating rod 403. The bottom of the inner wall of the feeding channel 2 is inclined towards the discharge direction. The bottom of the material feeding wheels 404 overlaps the inclined surface inside the feeding channel 2. Specifically, the inclined feeding channel 2 is used to realize the self-flow of materials. When the drying discharge bin 4 moves horizontally back and forth, the weight of the material feeding frame 402 plus the mass of the counterweight rotating rod 403 generates a constant downward pressure, ensuring that the material feeding wheels 404 on the material feeding frame 402 are always close to the bottom plate. The material feeding wheels 404 are driven by the friction of the feeding channel 2 to rotate and scrape off the adhered materials, solving the problem of adhesion and clumping of high-moisture plastic fragments during the conveying process and improving the drying effect of the drying bin.

[0039] In a further embodiment of the present invention, an abutting component 7 is installed in the feeding channel 2. One end of the abutting component 7 abuts against the drying discharge bin 4, and the other end abuts against the limiting screen basin 301 at an incline. When the drying discharge bin 4 moves toward the crushing chamber 3, the abutting component 7 pushes up the limiting screen basin 301. Specifically, the abutting component 7 is used to drive the limiting screen basin 301 to move up and down repeatedly when the drying discharge bin 4 moves horizontally back and forth. When the drying discharge bin 4 moves toward the crushing chamber 3 under the pressure of the pressing rod 604 on the telescopic cutter shaft 6, it pushes... The moving abutment component 7 lifts the limiting screen basin 301, shortening the distance between the bottom of the limiting screen basin 301 and the crushing blade 603, and further crushing the plastic that is not completely crushed at the bottom of the basin. When the pressing rod 604 enters the groove 407 and no longer applies pressure to the drying discharge bin 4, the drying discharge bin 4 moves back, increasing the distance between the limiting screen basin 301 and the crushing blade 603. Through the reciprocating lifting and lowering of the limiting screen basin 301, it can quickly screen down the completely crushed plastic and throw up the plastic that has been crushed a second time, thus accelerating the efficiency of plastic dismantling and crushing.

[0040] In a further embodiment of the present invention, the abutting component 7 includes a push-pull frame 701 slidably installed in the feeding channel 2. An abutting rod 702 extending out of the feeding channel 2 is fixedly connected to one side of the push-pull frame 701, and wedge-shaped top blocks 703 are symmetrically fixedly connected to the other side. Wedge-shaped abutting blocks 304 that abut against each wedge-shaped top block 703 are symmetrically fixedly connected to the bottom of the limiting screen basin 301. Specifically, as the drying discharge bin 4 moves toward the crushing bin 3, it will push the entire push-pull frame 701 by contacting the abutting rod 702, causing the wedge-shaped top blocks 703 on the push-pull frame 701 to be lifted. The wedge-shaped abutment 304 on the limiting screen basin 301 lifts the limiting screen basin 301. At this time, the wedge-shaped top block 703 and the wedge-shaped abutment 304 still remain in an inclined abutment state. After the abutment rod 604 in the telescopic cutter shaft 6 rotates to the groove 407 on the guide ring 401, the limiting screen basin 301 presses down on the wedge-shaped abutment 304 on the push-pull frame 701 under the action of gravity, so that the entire abutment component 7 is reset and moved back. Thus, after the drying feed hopper 4 pushes the abutment component 7 again, it can continue to lift the limiting screen basin 301 to achieve the purpose of continuous vibrating screen.

[0041] In a further embodiment of the present invention, a heating element 8 is installed inside the drying hopper 4, and a blower blade 405 is rotatably installed on one side of the inner wall of the drying hopper 4. The transmission sleeve 601 is coaxially connected to the blower blade 405. A reset top spring 406 is symmetrically installed between the drying hopper 4 and the feeding channel 2. Specifically, the heating element 8, such as a heating wire or a heating plate, is set inside the drying hopper 4. When the telescopic cutter shaft 6 rotates, it drives the blower blade 405 to rotate, so that the airflow mixed with heat blows throughout the drying hopper 4 and the feeding channel 2, thereby achieving the drying treatment of the crushed plastic. The blower blade 405 can move together with the drying hopper 4, thereby increasing the airflow field range and improving the drying effect. The reset top spring 406 ensures that when the pressure rod 604 on the transmission sleeve 601 enters the groove 407 in the guide ring 401, the drying hopper 4 can reset and move back, thereby achieving continuous operation of the entire equipment.

[0042] In a further embodiment of the present invention, a lifting protrusion 704 is fixedly connected to the top of the wedge-shaped top block 703, and a handle 705 is installed on the top of the abutment rod 702. When the lifting protrusion 704 abuts against the wedge-shaped abutment block 304, the limiting screen basin 301 is raised above the feed inlet 201. Specifically, the lifting protrusion 704 also abuts against the wedge-shaped abutment block 304 on the limiting screen basin 301. If there is jamming inside the crushing chamber 3 or if parts need to be replaced or maintained, the entire abutment assembly 7 can be pulled towards the crushing chamber 3 by holding the handle 705. The wedge-shaped top block 703 will first abut against the wedge-shaped abutment block 304. When the stop block 304 contacts, the limiting screen basin 301 rises for the first time. Then, the raised protrusion 704 abuts against the wedge-shaped stop block 304, and the limiting screen basin 301 rises a second time. This time, the bottom of the limiting screen basin 301 completely leaves the feed inlet 201 in the feeding channel 2. The crushing chamber 3 is no longer limited by the limiting screen basin 301 and cannot move horizontally. The bottom of the crushing chamber 3 can be exposed by simply pulling it outward, so that the staff can quickly check and repair it. At the same time, even if the crushing chamber 3 is pulled out, it will not affect the transmission of the telescopic cutter shaft 6, and the inspection after the maintenance is completed is also more convenient.

[0043] In a further embodiment of the present invention, a storage box 9 is installed inside the frame 1. The top of the storage box 9 is provided with a receiving interface 901 located below the drying discharge bin 4. A maintenance receiving hopper 902 is rotatably hinged to one side of the storage box 9. Specifically, the bottom of the drying discharge bin 4 is open. The crushed and dried material will enter the storage box 9 after reaching the receiving interface 901 in the drying discharge bin 4. If it is necessary to pull out the crushing bin 3 to repair its internal parts, the maintenance receiving hopper 902 can be opened first to catch the material remaining in the crushing bin 3 and prevent it from falling out.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
