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

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] See also Figure 1-8The embodiment of the present invention provides a waste electronic product plastic dismantling equipment, 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 bin 3 and a drying discharge bin 4 are installed on the top of the feeding channel 2 and are connected. The feeding channel 2 is a pipe with a rectangular cross-section, which is used to receive the waste plastic disassembled and crushed by the crushing bin 3, and then let it enter the drying discharge bin 4. A limiting screen basin 301 inserted into the feeding channel 2 is movably installed at the bottom of the crushing bin 3. The limiting screen basin 301 is a basin-shaped screen with a specific mesh size. The edge of the screen basin is slidably connected to the inner wall of the crushing bin 3. It can be lifted and lowered reciprocatingly in the vertical direction. The crushed material needs to pass through this sieve hole for screening before it can enter the feeding channel 2 below. The driving member 5 is installed on the other side of the top of the frame 1. The end of the driving member 5 is connected with a telescopic knife shaft 6 that passes through the drying lower hopper 4 and enters the crushing bin 3. The drying lower hopper 4 is equipped with a guide ring 401 that abuts against the telescopic knife shaft 6 and a material diverter rack 402 that extends into the feeding channel 2. When the telescopic knife shaft 6 rotates, it drives the drying lower hopper 4 to move back and forth horizontally to push the limit screen basin 301 to lift and lower back and forth, and force the material diverter rack 402 to scrape the material in the feeding channel 2 back and forth.

[0033] Specifically, when the driving member 5 drives the telescopic blade shaft 6 to rotate, the telescopic blade shaft 6 will directly act on the guide ring 401, and the abutment between the guide ring 401 and the telescopic blade shaft 6 will drive the entire drying discharge bin 4 to perform horizontal reciprocating motion along the length direction of the feeding channel 2. The blade on the telescopic blade shaft 6 located in the crushing bin 3 rotates accordingly, and the waste electronic product plastics thrown in from the top of the crushing bin 3 are forcibly disassembled and impact-crushed. After crushing, the plastic fragments smaller than the sieve hole size fall into the feeding channel 2 through the sieve holes of the limiting screen basin 301 at the bottom. While the telescopic blade shaft 6 rotates, its special structure acts on the guide ring 401, driving the drying discharge bin 4 to move horizontally, and then this horizontal movement will be transmitted to the limiting screen basin 301, forcing the limiting screen basin 301 to continuously rise and fall, the screen basin moves downward, expands the discharge gap, accelerates the discharge of qualified crushed fragments, and the screen basin moves up and resets. At the same time, the large-sized materials or incompletely crushed materials retained on the screen basin are stirred to prevent them from clogging the sieve holes, and the oversized particles are lifted back to the crushing area. The secondary crushing is carried out in the field, and the periodic lifting of the screen basin forms a dynamic material discharge space, which greatly improves the screening efficiency and the discharge speed of the crushed materials, and avoids the clogging problem of the traditional fixed screen plate. After the screened fragments enter the feeding channel 2, they are within the range of the heat source of the drying and discharging bin 4. The horizontal reciprocating movement of the drying and discharging bin 4 brings multiple drying advantages. The mobile drying and discharging bin 4 makes the heat radiation or hot air coverage area change dynamically, ensuring that the plastic fragments at different positions can receive uniform and comprehensive heating. The slight vibration generated by the movement of the bin body is transmitted to the fragment layer, causing the fragments to roll and shift with each other, greatly reducing the dead corners of heating, improving the drying efficiency, evaporating water more thoroughly, and significantly reducing the residual moisture content on the surface of the fragments. At the same time, the material rack 402 scrapes back and forth in the feeding channel 2 to scrape off the wet fragments adhering to the channel wall or bottom, and uses the exciting force to loosen and break up the wet plastic blocks that have begun to stick to each other in the channel, effectively reducing the mutual adhesion problem of the material due to moisture, and creating good conditions for subsequent recycling and processing.

[0034] Compared with the prior art, the embodiment of the present invention sets a telescopic knife shaft 6 that passes through the drying bin and the crushing bin 3. When the driving member 5 drives it to rotate, it pushes the drying bin to move horizontally, and then cooperates with the lifting and lowering of the limit screen basin 301 to form a dynamic unloading space, so that the screening speed of the crushed plastic can be improved. The reciprocating movement of the drying bin 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 materials sticking to each other. The material rack 402 is driven by the displacement of the drying bin to scrape the feeding channel 2. Its reciprocating stroke generates an inertial excitation force of acceleration, which eliminates the material bridging phenomenon and breaks up the plastic agglomerated in the feeding channel 2, thereby improving the drying effect and 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 bin 3, and a pair of dust covers 303 are hinged in the feed hopper 302. Specifically, when the high-speed rotating cutter in the crushing bin 3 shears the material, a large amount of dust and fragments are splashed. The dust 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 complying with industrial hygiene standards, and at the same time enhancing the heat flow guidance efficiency of the drying system of the drying lower bin 4 in the feeding channel 2.

[0036] When the material is in the working state, the material is transported to the feed container 2 through the feed opening 201, and the feed container 2 is moved to the working state by the feed container 2. When the material is in the working state, the material is transported to the feed container 2 through the feed opening 201, and the feed opening 201 is moved to the working state by the feed container 2. When the material is in the working state, the material is transported to the feed container 2 through the feed opening 201, and the feed container 2 is moved to the working state by the feed container 2.

[0037] In a further embodiment of the present invention, the telescopic cutter shaft 6 includes a transmission sleeve 601 connected to the driving member 5, the driving member 5 is a driving motor, the output shaft of the driving motor and the transmission sleeve 601 are connected by a coupling, a shaft rod 602 is inserted in the transmission sleeve 601, the shaft rod 602 is inserted into the inner hole of the transmission sleeve 601, circumferential locking is achieved by a flat key, and axial sliding is possible, a crushing knife 603 is installed in the crushing bin 3, a pressure rod 604 is installed on the transmission sleeve 601, a groove 407 is provided on the guide ring 401, the pressure rod 604 is in contact with the guide ring 401, and static blades matching the crushing knife 603 are installed on both sides of the inner wall of the crushing bin 3. The driving member 5 drives the transmission sleeve 601 to rotate, and drives the shaft 602 to rotate synchronously through the transmission sleeve 601, so that the dynamic crushing knife 603 rotates at high speed in the crushing bin 3, and the material enters the shearing area formed by the dynamic crushing knife 603 and the static blade to be crushed. Since the shaft 602 can move axially in the transmission sleeve 601, the crushing bin 3 can be pulled out smoothly, so that the crushing bin 3 can be easily pulled out for inspection and maintenance. When the pressure rod 604 is rotated from the groove 407 in the guide ring 401 to other positions, the drying lower bin 4 gradually moves toward the direction of the crushing bin 3. When the pressure rod 604 is rotated back into the groove 407, the drying lower 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 rack 402 is hinged to the drying lower material bin 4, and the other side is rotatably connected to a counterweight rotating rod 403, and a plurality of 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 and inclined toward the discharge direction. The bottom of the material feeding wheel 404 overlaps the inclined surface in the feeding channel 2. Specifically, the inclined feeding channel 2 is used to realize the self-flow of materials. When the drying lower material bin 4 moves back and forth horizontally, the weight of the material feeding rack 402 plus the mass of the counterweight rotating rod 403 generate a constant downward pressure, ensuring that the material feeding wheel 404 on the material feeding rack 402 is always close to the bottom plate. The material feeding wheel 404 is driven by the friction force of the feeding channel 2 to rotate and cut and scrape off the adhered material, thereby solving the adhesion and agglomeration problems of high-humidity plastic fragments during the transportation process and improving the drying effect of the drying bin.

[0039] In a further embodiment of the present invention, an abutment assembly 7 is installed in the feeding channel 2, one end of the abutment assembly 7 abuts and cooperates with the drying lower bin 4, and the other end abuts against the limit screen basin 301 at an angle. When the drying lower bin 4 moves toward the crushing bin 3, the limit screen basin 301 is lifted up by the abutment assembly 7. Specifically, the added abutment assembly 7 is used to realize the reciprocating horizontal movement of the drying lower bin 4 and drive the limit screen basin 301 to rise and fall. When the drying lower bin 4 moves toward the crushing bin 3 under the extrusion of the pressure rod 604 on the telescopic knife shaft 6, the limit screen basin 301 is pushed up and down. The movable abutment component 7 is used to lift the limiting screen basin 301, so that the distance between the bottom of the limiting screen basin 301 and the crushing knife 603 is shortened, and the plastic that is not completely crushed at the bottom of the basin is crushed again. When the abutment rod 604 enters the groove 407 and does not apply pressure to the drying lower bin 4, the drying lower bin 4 moves back, so that the distance between the limiting screen basin 301 and the crushing knife 603 becomes longer. Through the reciprocating lifting and lowering of the limiting screen basin 301, it can quickly screen out and crush the completely plastic, and can also throw up the secondarily crushed plastic, thereby speeding up the efficiency of plastic disassembly and crushing.

[0040] In a further embodiment of the present invention, the abutment assembly 7 includes a push-pull frame 701 slidably installed in the feeding channel 2, one side of the push-pull frame 701 is fixedly connected to an abutment rod 702 extending out of the feeding channel 2, and the other side is symmetrically fixedly connected to a wedge-shaped top block 703, and the bottom of the limiting screen basin 301 is symmetrically fixedly connected to a wedge-shaped abutment block 304 abutting and cooperating with each wedge-shaped top block 703. Specifically, when the drying lower bin 4 moves toward the crushing bin 3, it will push the entire push-pull frame 701 by contacting the abutment rod 702, so that the wedge-shaped top block 703 on the push-pull frame 701 is lifted up The wedge-shaped stop block 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 stop block 304 still maintain an inclined state of abutting each other. After the pressure rod 604 in the telescopic knife shaft 6 rotates to the groove 407 on the guide ring 401, the limiting screen basin 301 presses down the wedge-shaped stop block 304 on the push-pull frame 701 under the action of gravity, so that the entire abutment assembly 7 is reset and moved back, so that the limiting screen basin 301 can continue to be lifted after the drying lower hopper 4 pushes the abutment assembly 7 again, thereby achieving the purpose of continuous vibrating screening.

[0041] In a further embodiment of the present invention, a heating element 8 is installed in the drying lower material bin 4, and a blowing fan blade 405 is rotatably installed on one side of the inner wall of the drying lower material bin 4. The transmission sleeve 601 is coaxially connected to the blowing fan blade 405, and a reset top spring 406 is symmetrically installed between the drying lower material bin 4 and the feeding channel 2. Specifically, the heating element 8, such as a heating wire or a heating plate, is arranged inside the drying lower material bin 4. When the telescopic knife shaft 6 rotates, it drives the blowing fan blade 405 to rotate and allows the airflow mixed with heat to blow throughout the drying lower material bin 4 and the feeding channel 2, thereby achieving drying processing of the broken plastic. The blowing fan blade 405 can move with the drying lower material bin 4, so that the airflow field range is increased and the drying effect is improved. 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 lower material bin 4 can be reset and moved back, thereby achieving continuous operation of the entire equipment.

[0042] When the lifting protrusion 704 abuts against the wedge-shaped abutting block 304, the limiting screen basin 301 is lifted to the top of the feed inlet 201. Specifically, the lifting protrusion 704 also abuts against the wedge-shaped abutting block 304 on the limiting screen basin 301. If the crushing bin 3 is stuck or parts need to be replaced and maintained, the handle 705 can be held to pull the entire abutting assembly 7 toward the crushing bin 3, and the wedge-shaped top block 703 will first abut against the wedge-shaped abutting block 304. The stop block 304 contacts, and the limiting screen basin 301 rises for the first time. Then the lifting protrusion 704 contacts the wedge-shaped stop block 304, and the limiting screen basin 301 rises for the second time. This time, the bottom of the limiting screen basin 301 completely leaves the feed port 201 in the feeding channel 2, and the crushing bin 3 is no longer limited by the limiting screen basin 301 and cannot move horizontally. It is only necessary to pull the crushing bin 3 outward to expose its bottom, so that the staff can quickly check and repair it. At the same time, even if the crushing bin 3 is pulled out, it will not affect the transmission of the telescopic knife shaft 6, and the inspection after the maintenance is completed will also be more convenient.

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

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
