Description

Technical Field

[0001] The present invention relates to the field related to circuit board processing technology, and in particular to an automated production line suitable for metal recycling of circuit boards. Background Art

[0002] This automated production line is a device for physically screening and recovering metal objects in circuit boards. The gravity sorting method achieves efficient recovery of metal on the surface of circuit boards through differences in material density. Its core lies in utilizing the difference in sedimentation speed between metals (such as copper and aluminum) and non-metals (plastics and glass fibers). The pretreated mixed material enters equipment such as shakers and jigs. Under the action of vibration or pulsed water flow, high-density metal particles quickly settle to form a bottom enrichment layer, while low-density non-metals are separated and discharged with the water flow or air flow. This method can initially enrich metals (recovery rate > 85%) and reduce the subsequent sorting load. It is often used in conjunction with magnetic separation and eddy current sorting to improve purity. It has the characteristics of low cost and strong adaptability. It is a key pretreatment step in metal recycling for circuit boards.

[0003] Existing automated production lines for circuit board metal recycling have certain shortcomings. After the circuit boards are crushed, they need to be screened using equipment such as a shaker or jig. The shaker only performs a one-way reciprocating motion when in use, which can only provide forward force for the particles. The screening of the particles mainly relies on the pulsed water flow combined with the chute structure, which makes it difficult to complete the screening operation quickly, reducing its screening efficiency. Secondly, during the circuit board metal recycling operation, the circuit boards need to be crushed. The particles generated after the circuit boards are crushed will cause blockage during the transportation process. The operation of equipment such as a shaker or jig can only solve the screening problem, but cannot simultaneously solve the particle blockage problem, and its functionality is single.

[0004] The screening of particles in traditional automated production lines mainly relies on pulsed water flow combined with a chute structure, which makes it impossible to complete the screening operation of particles quickly, reduces its screening efficiency, and cannot simultaneously solve the problem of particle blockage.

[0005] In summary, the screening of particles in traditional automated production lines in the existing technology mainly relies on pulsed water flow combined with a chute structure, which makes it impossible to quickly complete the screening operation of particles, reduces its screening efficiency, and cannot simultaneously solve the problem of particle blockage. Summary of the Invention

[0006] The present invention provides an automated production line suitable for metal recycling of circuit boards, which can solve the technical problem that the milling processing device in the prior art has no auxiliary material turning structure and cannot be applied to the processing operation of the double-sided mold structure.

[0007] An automated production line suitable for recycling metal from circuit boards, comprising a feed rack, a crusher and a screener, wherein the screener is fixedly mounted on the front end outer surface of the crusher, the feed rack is fixedly mounted on the rear end outer surface of the crusher, the screener comprises a drive disc, a screen disc and a support seat, the drive disc is movably mounted on the upper end outer surface of the support seat, the screen disc is movably mounted on the upper end outer surface of the drive disc, the drive disc and the support seat are movably connected via the drive rack, the screen disc and the drive disc are movably connected via four groups of connecting parts, the upper surface of the screen disc is provided with an inclined chute-like structure, and one end of the drive rack drives a roller via an eccentric wheel.

[0008] As a further technical solution of the present invention, a support seat is installed at the lower end of the driving frame, and the other end of the driving frame is slidably connected to the support seat by casters, and the two sets of eccentric wheels and the driving frame are movably connected by a rotating rod. The screener can be used to screen the crushed circuit board particles. When in use, the particles are introduced into the upper end of the screening plate by the feeding hopper. The upper end of the screening plate is a chute-shaped structure, and water is supplied to the upper end of the screening plate through the water trough, so that the water flow flushes the particles on the upper end of the screening plate. Because the metal particles have a large density, they will be retained in the chute structure of the screening plate during the water flushing process. With the reciprocating motion of the screening plate, the metal particles are discharged from the front end of the screening plate, while the non-metallic particles have a smaller density. During the water flushing process, in conjunction with the inclined screening plate, the chute structure moves downward step by step during the reciprocating motion of the screening plate, and are discharged through the side of the screening plate.

[0009] As a further technical solution of the present invention, drivers for use with the drive frame are fixedly installed on both sides of the support seat. An electric motor for driving a group of eccentric wheels is installed inside one group of drivers, and a rotating shaft for docking with the other group of eccentric wheels is provided inside the other group of drivers. In order to improve the use effect of the screening disc, the screening disc is driven to reciprocate by a driving disc, so that the particles are quickly separated. During operation, the eccentric wheel is driven by the electric motor, and the drive frame is driven by the two groups of eccentric wheels in conjunction with the rotating rod, so that the drive frame drives the drive disc, and the drive disc and the screening disc move synchronously. At this time, the movement trajectory of the screening disc is back and forth and up and down. The movement of the screening disc can make the particles vibrate, thereby accelerating the separation of the particles.

[0010] As a further technical solution of the present invention, as a further technical solution of the present invention, the connecting part includes a limiting slide and a movable slider, the movable slider is movably installed on the inner side of the upper end of the limiting slide, the lower end of the limiting slide and the driving disk are fixedly connected, and the upper end of the movable slider and the screen disk are fixedly connected. By utilizing the setting of the connecting part, a movable limiting structure can be formed between the driving disk and the screen disk. On the basis of the two-way movement of the screen disk, an oblique downward motion trajectory is added to the screen disk, so that the particulate matter continues to move downward during the forward movement.

[0011] As a further technical solution of the present invention, an inclined slide groove is provided on the inner side of the limit slide, and a limit slide groove is provided on the side of the movable slide block. The limit slide and the movable slide block are slidably connected through the inclined slide groove. When the driving plate drives the screening plate to move, the setting of the connection part is utilized to make the screening plate move laterally on the upper part of the driving plate along the inclined direction of the inclined slide groove. The eccentric wheel exerts an up and down movement in the front and back directions on the screening plate, so that the particles on the screening plate continuously move forward while vibrating, and the up and down movement makes the particles vibrate up and down, and the front and back The movement makes the particles move forward continuously, and the action of the water flow drives the particles to move laterally, completing the particle screening operation. The setting of the connection part makes the screen plate and the driving plate movably connected, and at the same time limits the movement direction of the screen plate. When the driving plate moves, the screen plate moves obliquely under the action of the inclined slide. Its function is to apply a lateral movement force to the particles on the screen plate, so that the lateral movement of the particles is not completely dependent on the action of the water flow, reducing water consumption while accelerating the particle screening efficiency, so that the screen plate has a three-way screening movement structure.

[0012] As a further technical solution of the present invention, a feeding hopper is installed at the upper end of the screening plate, a sub-hopper is fixedly installed at the bottom of the feeding hopper, the feeding hopper and the sub-hopper are fixed by a docking pipe, a vibrating rod is movably installed on the inner side of the sub-hopper, and the sub-hopper and the vibrating rod are slidingly connected by an elliptical slide. By utilizing the setting of the vibrating rod, the vibration generated when the screening plate moves can be fully utilized, so that the vibrating rod can reciprocate in the elliptical slide, and the movement trajectory of the vibrating rod is elliptical, so that the vibrating rod can well cover the feeding area of ​​the sub-hopper, and the vibrating rod can be used to impact the particulate matter in the sub-hopper to avoid the blockage of particulate matter in the sub-hopper.

[0013] As a further technical solution of the present invention, several groups of partition plates are fixedly installed on the inner side of the distribution hopper, and the several groups of partition plates are symmetrically arranged in an eight-shaped shape. By utilizing the setting of the dry group of partition plates, the particles can be diffused and distributed when the distribution hopper is performing the particle discharging operation, and the particles are evenly discharged onto the surface of the screen plate. At the same time, the setting of the vibrating rod can effectively prevent the particles from being blocked at the feed end of the partition plate.

[0014] As a further technical solution of the present invention, a feed port is provided at the upper end of the crusher, a discharge nozzle is fixedly installed at the front end of the crusher, a lifting bushing is movably installed on the inner side of the discharge nozzle, the lifting bushing and the screen plate are movably connected by a pull rod, and the setting of the lifting bushing is utilized to make the discharge nozzle of the crusher have a synchronous vibration structure. When the screen plate moves, the setting of the pull rod is utilized to make the screen plate pull the lifting bushing through the pull rod, so that the lifting bushing moves up and down in the discharge nozzle. When the discharge nozzle is performing the discharge operation, the particles in the discharge nozzle vibrate up and down to prevent it from being blocked.

[0015] As a further technical solution of the present invention, both ends of the pull rod are movably connected by a ball shaft, and the bottom of the lifting bushing is inclined. Because the screening plate adopts a multi-directional motion structure design, in order to cooperate with the use of the screening plate, a ball shaft is used to connect the two ends of the pull rod. When the pull rod pulls the lifting bushing up and down, the pull rod can make corresponding angle changes according to the movement direction of the screening plate.

[0016] As a further technical solution of the present invention, a water supply trough is fixedly installed on the upper end of the screening plate, and a conveyor belt is movably installed on the inner side of the feed rack. The setting of the water supply trough can supply water to the upper end of the screening plate, and the feed rack can use the conveyor belt to transport the circuit board to the inside of the crusher for crushing.

[0017] Beneficial effects of the present invention:

[0018] 1. By setting up the screening plate and the connecting part, when used in the automated production line suitable for circuit board metal recycling, it is provided with a multi-directional material vibration auxiliary structure to improve the efficiency of particle separation and screening;

[0019] During operation, the sieve can be used to screen the crushed circuit board particles. When in use, the granules are introduced into the upper end of the sieve plate by the feed hopper. The upper end of the sieve plate is a chute-shaped structure. Water is supplied to the upper end of the sieve plate through the water trough, so that the water flow flushes the granules on the upper end of the sieve plate. Metal particles have a large density and will be retained in the chute structure of the sieve plate during the water flushing process. With the reciprocating motion of the sieve plate, the metal particles are discharged from the front end of the sieve plate, while non-metallic particles have a small density. During the water flushing process, they cooperate with the inclined sieve plate and move downward step by step through the chute structure during the reciprocating motion of the sieve plate, and are discharged through the side of the sieve plate.

[0020] In order to improve the use effect of the screening disc, a driving disc is set to drive the screening disc to move back and forth, so that the particles can be separated quickly. During operation, the eccentric wheel is driven by an electric motor, and the driving frame is driven by two sets of eccentric wheels in conjunction with the rotating rod, so that the driving frame drives the driving disc, so that the driving disc and the screening disc move synchronously. At this time, the motion trajectory of the screening disc is forward and backward and up and down, which is a bidirectional motion trajectory. The movement of the screening disc can make the particles vibrate, thereby accelerating the separation of particles.

[0021] The setting of the connecting part can form a movable limiting structure between the driving disc and the screening disc. On the basis of the two-way movement of the screening disc, an oblique downward movement trajectory is added to the screening disc, so that the particles move downward continuously in the process of moving forward. When the driving disc drives the screening disc to move, the setting of the connecting part is used to make the screening disc move laterally on the upper part of the driving disc along the inclined direction of the inclined chute. The up and down movement in the front and rear directions applied to the screening disc by the eccentric wheel makes the particles on the screening disc move forward continuously while vibrating, and the up and down movement makes the particles increase The downward vibration and forward and backward movement make the particles move forward continuously, and the action of water flow drives the particles to move laterally, completing the particle screening operation. The setting of the connecting part makes the screen disc and the driving disc movable, and at the same time limits the moving direction of the screen disc. When the driving disc moves, the screen disc moves obliquely under the action of the inclined slide, which exerts a lateral movement force on the particles on the screen disc, so that the lateral movement of the particles is not completely dependent on the action of water flow, thereby reducing water consumption and accelerating the particle screening efficiency, so that the screen disc has a three-way screening movement structure.

[0022] 2. By setting up a vibrating rod and a hopper, the use of the sieve plate is optimized when used in the automated production line suitable for circuit board metal recycling. The sieve plate's own movement is fully utilized to avoid blockage during feeding, making the particle discharge more uniform.

[0023] During use, the setting of the vibrating rod can make full use of the vibration generated by the movement of the screen disc, so that the vibrating rod can reciprocate in the elliptical slide. The movement trajectory of the vibrating rod is elliptical, so that the vibrating rod can well cover the feeding area of ​​the distribution hopper. The vibrating rod can hit the particles in the distribution hopper to avoid the blockage of particles in the distribution hopper. The setting of the dry group partition plate can be used to perform diffusion-type distribution of the particles when the distribution hopper is performing the particle discharging operation, and the particles are evenly discharged to the surface of the screen disc. At the same time, the setting of the vibrating rod can effectively prevent the particles from being blocked at the feeding end of the partition plate.

[0024] 3. By setting the pull rod and lifting bushing, when used in the automated production line for circuit board metal recycling, the use of the screening plate can simultaneously solve the problem of crusher discharge blockage and improve the operation stability of the equipment;

[0025] During operation, the setting of the lifting bushing is utilized to make the discharge nozzle of the crusher have a synchronous vibration structure. When the screening plate moves, the setting of the pull rod is utilized to make the screening plate pull the lifting bushing through the pull rod, so that the lifting bushing moves up and down in the discharge nozzle. When the discharge nozzle is performing the discharge operation, the particles in the discharge nozzle vibrate up and down to prevent it from being blocked. Because the screening plate adopts a multi-directional motion structure design, in order to cooperate with the use of the screening plate, a ball shaft is used to connect the two ends of the pull rod. When the pull rod pulls the lifting bushing up and down, the pull rod can make corresponding angle changes according to the movement direction of the screening plate.

[0036] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0037] like Figures 1-8 As shown, an automated production line suitable for metal recycling of circuit boards includes a feed rack 6, a crusher 7 and a screener 10. The screener 10 is fixedly mounted on the front end outer surface of the crusher 7, and the feed rack 6 is fixedly mounted on the rear end outer surface of the crusher 7. The screener 10 includes a drive disc 1, a screen disc 3 and a support seat 2. The drive disc 1 is movably mounted on the upper end outer surface of the support seat 2, and the screen disc 3 is movably mounted on the upper end outer surface of the drive disc 1. The drive disc 1 and the support seat 2 are movably connected by a drive rack 14, and the screen disc 3 and the drive disc 1 are movably connected by four groups of connecting parts 13. The upper surface of the screen disc 3 is provided with a chute-like structure arranged obliquely, and one end of the drive rack 14 drives the roller through the eccentric wheel 12.

[0038] In order to improve the screening efficiency of circuit board particles, Figure 3 As shown, a support seat 2 is installed at the lower end of the driving frame 14, and the other end of the driving frame 14 is slidably connected to the support seat 2 by a caster 15, and the two sets of eccentric wheels 12 and the driving frame 14 are movably connected by a rotating rod 16. The screener 10 can be used to screen the crushed circuit board particles. When in use, the hopper 8 introduces the particles into the upper end of the screening plate 3. The upper end of the screening plate 3 is a chute-shaped structure, and water is supplied to the upper end of the screening plate 3 through the water supply trough 9, so that the water flow flushes the particles on the upper end of the screening plate 3. Because the metal particles have a large density, they will be retained in the chute structure of the screening plate 3 during the water flushing process. With the reciprocating motion of the screening plate 3, the metal particles are discharged from the front end of the screening plate 3, while the non-metallic particles have a smaller density. During the water flushing process, in conjunction with the inclined screening plate 3, the chute structure moves downward step by step during the reciprocating motion of the screening plate 3 and is discharged through the side of the screening plate 3.

[0039] Both sides of the support seat 2 are fixedly installed with a driver 4 for use with a drive frame 14. A motor 11 for driving a group of eccentric wheels 12 is installed inside one group of drivers 4, and a rotating shaft for docking with another group of eccentric wheels 12 is provided inside the other group of drivers 4. In order to improve the use effect of the screening plate 3, the screening plate 3 is driven to reciprocate by the driving plate 1, so that the particles are quickly separated. During operation, the eccentric wheel 12 is driven by the motor 11, and the driving frame 14 is driven by the two groups of eccentric wheels 12 in conjunction with the rotating rod 16, so that the driving frame 14 drives the driving plate 1, so that the driving plate 1 and the screening plate 3 move synchronously. At this time, the movement trajectory of the screening plate 3 is back and forth and up and down. The movement of the screening plate 3 can make the particles vibrate, thereby accelerating the separation of the particles.

[0040] The connecting part 13 includes a limiting slide 18 and a movable slider 20. The movable slider 20 is movably installed on the inner side of the upper end of the limiting slide 18. The lower end of the limiting slide 18 is fixedly connected to the driving disk 1, and the upper end of the movable slider 20 is fixedly connected to the screening plate 3. By utilizing the setting of the connecting part 13, a movable limiting structure can be formed between the driving disk 1 and the screening plate 3. On the basis of the two-way movement of the screening plate 3, an oblique downward motion trajectory is added to the screening plate 3, so that the particles continue to move downward during the forward movement.

[0041] An inclined slide groove 19 is provided on the inner side of the limiting slide 18, and a limiting slide groove 17 is provided on the side of the moving slider 20. The limiting slide 18 and the moving slider 20 are slidably connected through the inclined slide groove 19. When the driving disc 1 drives the screening disc 3 to move, the setting of the connecting part 13 is utilized to make the screening disc 3 move laterally on the upper part of the driving disc 1 along the inclined direction of the inclined slide groove 19. The up and down movement of the eccentric wheel 12 on the screening disc 3 in the front and rear directions makes the particle size on the screening disc 3 continuously move forward while vibrating, and the up and down movement makes the particle size vibrate up and down, and the front and rear movement The movement causes the particles to move forward continuously, and the action of the water flow drives the particles to move laterally, completing the particle screening operation. The setting of the connecting part 13 enables the active connection between the screening plate 3 and the driving plate 1, and at the same time limits the moving direction of the screening plate 3. When the driving plate 1 moves, the screening plate 3 moves obliquely under the action of the inclined slide 19, which exerts a lateral movement force on the particles on the screening plate 3, so that the lateral movement of the particles is not completely dependent on the action of the water flow, thereby reducing water consumption and accelerating the particle screening efficiency, so that the screening plate 3 has a three-way screening movement structure.

[0042] To solve the problem of particle blockage, such as Figure 5As shown, a feeding hopper 8 is installed at the upper end of the screening disc 3, and a sub-hopper 23 is fixedly installed at the bottom of the feeding hopper 8. The feeding hopper 8 and the sub-hopper 23 are docked and fixed by a docking pipe 24. A vibrating rod 21 is movably installed on the inner side of the sub-hopper 23. The sub-hopper 23 and the vibrating rod 21 are slidingly connected by an elliptical slide 22. By utilizing the setting of the vibrating rod 21, the vibration generated when the screening disc 3 moves can be fully utilized, so that the vibrating rod 21 can reciprocate in the elliptical slide 22. The movement trajectory of the vibrating rod 21 is elliptical, so that the vibrating rod 21 can well cover the feeding area of ​​the sub-hopper 23. The vibrating rod 21 can be used to impact the particulate matter in the sub-hopper 23 to avoid the blockage of particulate matter in the sub-hopper 23.

[0043] Several groups of partition plates 25 are fixedly installed on the inner side of the distribution hopper 23. The several groups of partition plates 25 are symmetrically arranged in an eight-shaped shape. By utilizing the arrangement of the dry group of partition plates 25, the particles can be diffused and distributed when the distribution hopper 23 is performing the particle discharging operation. The particles are evenly discharged onto the surface of the screening plate 3. At the same time, the arrangement of the vibrating rod 21 can effectively prevent the particles from being blocked at the feed end of the partition plate 25.

[0044] A feed port is provided at the upper end of the crusher 7, and a discharge nozzle 5 is fixedly installed at the front end of the crusher 7. A lifting bushing 28 is movably installed on the inner side of the discharge nozzle 5. The lifting bushing 28 and the screening plate 3 are movably connected by a pull rod 26. The setting of the lifting bushing 28 is used to make the discharge nozzle 5 of the crusher 7 have a synchronous vibration structure. When the screening plate 3 moves, the setting of the pull rod 26 is used to make the screening plate 3 pull the lifting bushing 28 through the pull rod 26, so that the lifting bushing 28 moves up and down in the discharge nozzle 5. When the discharge nozzle 5 is performing the discharge operation, the particles in the discharge nozzle 5 vibrate up and down to prevent it from being blocked.

[0045] Both ends of the pull rod 26 are movably connected by a ball shaft 27, and the bottom of the lifting bushing 28 is set at an angle. Because the screening plate 3 adopts a multi-directional motion structure design, in order to cooperate with the use of the screening plate 3, the ball shaft 27 is used to connect the two ends of the pull rod 26. When the pull rod 26 pulls the lifting bushing 28 up and down, the pull rod 26 can make corresponding angle changes according to the movement direction of the screening plate 3.

[0046] A water supply trough 9 is fixedly installed on the upper end of the screening plate 3, and a conveyor belt is movably installed on the inner side of the feeding rack 6. The setting of the water supply trough 9 can supply water to the upper end of the screening plate 3, and the feeding rack 6 can use the conveyor belt to transport the circuit board to the inside of the crusher 7 for crushing.

[0047] When in use, by providing the screening plate 3 and the connecting portion 13, when the automated production line suitable for metal recycling of circuit boards is used, it is provided with a multi-directional material vibration auxiliary structure, thereby improving the efficiency of particle separation and screening;

[0048] During operation, the sieve 10 can be used to screen the crushed circuit board particles. When in use, the granular matter is introduced into the upper end of the sieve plate 3 by the feed hopper 8. The upper end of the sieve plate 3 is a chute-shaped structure. Water is supplied to the upper end of the sieve plate 3 through the water supply trough 9, so that the water flow flushes the granular matter on the upper end of the sieve plate 3. Due to the large density of metal particles, they will be retained in the chute structure of the sieve plate 3 during the water flushing process. With the reciprocating motion of the sieve plate 3, the metal particles are discharged from the front end of the sieve plate 3, while the non-metallic particles have a small density. During the water flushing process, they cooperate with the inclined sieve plate 3. During the reciprocating motion of the sieve plate 3, the chute structure moves downward step by step and is discharged through the side of the sieve plate 3.

[0049] In order to improve the use effect of the screening material plate 3, a driving plate 1 is provided to drive the screening material plate 3 to reciprocate, so that the particles are quickly separated. During operation, the motor 11 is used to drive the eccentric wheel 12, and the two sets of eccentric wheels 12 cooperate with the rotating rod 16 to drive the driving frame 14, so that the driving frame 14 drives the driving plate 1, so that the driving plate 1 and the screening material plate 3 move synchronously. At this time, the movement trajectory of the screening material plate 3 is forward and backward and up and down, which is a bidirectional movement trajectory. The movement of the screening material plate 3 can make the particles vibrate, thereby accelerating the separation of the particles.

[0050] The setting of the connecting part 13 can form a movable limiting structure between the driving disc 1 and the screening disc 3. On the basis of the two-way movement of the screening disc 3, an oblique downward movement trajectory is added to the screening disc 3, so that the particles continue to move downward in the process of moving forward. When the driving disc 1 drives the screening disc 3 to move, the setting of the connecting part 13 is utilized to make the screening disc 3 move laterally on the upper part of the driving disc 1 along the inclined direction of the inclined chute 19. The up and down movement in the front and rear directions imposed by the eccentric wheel 12 on the screening disc 3 makes the particles on the screening disc 3 continue to move forward while vibrating, and the up and down movement makes the particles move downward. The particle size vibrates up and down, and the forward and backward movement causes the particles to move forward continuously. The action of the water flow drives the particles to move laterally, completing the particle screening operation. The setting of the connecting portion 13 makes the screening plate 3 and the driving plate 1 movably connected, and at the same time limits the moving direction of the screening plate 3. When the driving plate 1 moves, the screening plate 3 moves obliquely under the action of the inclined chute 19. Its function is to apply a lateral movement force to the particles on the screening plate 3, so that the lateral movement of the particles is not completely dependent on the action of the water flow, reducing water consumption while accelerating the particle screening efficiency, so that the screening plate 3 has a three-way screening movement structure;

[0051] By providing the vibrating rod 21 and the dividing hopper 23, when the automated production line suitable for metal recycling of circuit boards is used, the use of the screening plate 3 is optimized, the movement of the screening plate 3 itself is fully utilized, and the blocking phenomenon during feeding is avoided, so that the particle discharge is more uniform;

[0052] When in use, the setting of the vibrating rod 21 can make full use of the vibration generated by the movement of the screening plate 3, so that the vibrating rod 21 can reciprocate in the elliptical slide 22, and the movement trajectory of the vibrating rod 21 is elliptical, so that the vibrating rod 21 can well cover the feeding area of ​​the sub-hopper 23, and the vibrating rod 21 can hit the particles in the sub-hopper 23 to avoid the particle blockage in the sub-hopper 23. The setting of the dry group dividing plate 25 can be used to diffuse the particles when the sub-hopper 23 is discharging the particles, and the particles are evenly discharged to the surface of the screening plate 3. At the same time, the setting of the vibrating rod 21 can effectively prevent the particles from being blocked at the feeding end of the dividing plate 25.

[0053] By providing the pull rod 26 and the lifting bushing 28, when the automated production line for metal recycling of circuit boards is used, the sieve tray 3 is used to simultaneously solve the problem of material discharge blockage of the crusher 7, thereby improving the operational stability of the equipment.

[0054] During operation, the setting of the lifting bushing 28 is utilized to make the discharge nozzle 5 of the crusher 7 have a synchronous vibration structure. When the screening plate 3 moves, the setting of the pull rod 26 is utilized to make the screening plate 3 pull the lifting bushing 28 through the pull rod 26, so that the lifting bushing 28 moves up and down in the discharge nozzle 5. When the discharge nozzle 5 is discharging, the particles in the discharge nozzle 5 vibrate up and down to prevent it from being blocked. Because the screening plate 3 adopts a multi-directional motion structure design, in order to cooperate with the use of the screening plate 3, a ball shaft 27 is used to connect the two ends of the pull rod 26. When the pull rod 26 pulls the lifting bushing 28 up and down, the pull rod 26 can make corresponding angle changes according to the movement direction of the screening plate 3.

[0055] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
