Description

Technical Field

[0001] This utility model is a waste circuit board recycling device, belonging to the field of circuit board recycling. Background Technology

[0002] Waste circuit boards refer to the supporting structures for electronic components and circuit connections. They are used to realize the layout design of complex circuits and the transmission of electrical signals in electrical and electronic equipment. When electronic equipment is damaged and discarded, waste circuit boards contain metal resources, such as rare metals like gold and silver, so they need to be recycled through waste circuit board recycling equipment.

[0003] In existing technologies, waste circuit boards are crushed using crushing rollers. The crushed circuit boards are then screened using a screening cylinder and screen plate, resulting in better size uniformity and facilitating subsequent processing. Furthermore, the connecting mechanism drives the screening cylinder and screen plate to move left and right at the lower end of the crushing chamber, improving actual screening efficiency. However, existing waste circuit board recycling devices use a reciprocating motion mechanism to drive the screen plate to swing, causing the circuit board fragments falling onto the screen plate to move continuously and be screened through the holes in the screen plate. Some screening mechanisms also use… The vibration mechanism drives the screen plate to vibrate, further improving the screening effect. However, these screening methods are relatively simple. Most circuit boards move back and forth in one direction with a small amplitude, making it difficult to screen quickly. Furthermore, the vibration amplitude is difficult to adjust. Since the particle size, shape, and density of circuit board fragments vary, for circuit board fragments with smaller particle size and higher density, it is necessary to appropriately increase the vibration amplitude to make the material move more vigorously on the screen surface, thereby passing through the screen holes faster. Conversely, the amplitude should be reduced. Therefore, the screening effect of waste circuit board recycling devices that are difficult to adjust the amplitude is poor. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waste circuit board recycling device to solve the problems mentioned in the background technology. This utility model can improve the screening efficiency of circuit board fragments.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a waste circuit board recycling device, comprising a machine body and a screening frame, wherein a servo motor is installed on one side of the machine body, a transmission mechanism is provided on one side of the servo motor, and two sets of crushing rollers are movably connected inside the machine body through bearings.

[0006] A screening frame is provided in the middle of the machine body. Multiple sets of support legs are fixed to the bottom of the screening frame, and a fixed plate is connected to the bottom of the support legs by ball bearings. One side of the fixed plate is welded to the inner wall of the machine body. Both ends of the screening frame are slidably connected to connecting blocks by first sliders. One side of the connecting block is slidably connected to a connecting rod by a second slider. One end of the connecting rod is provided with a reciprocating motion mechanism. Multiple sets of rubber sleeves are fixedly connected to the top of the fixed plate. The bottom of the rubber sleeves abuts against a top block. An adjustment mechanism is provided at the bottom of the top block. Guide mechanisms are provided on both sides of the screening frame.

[0007] Furthermore, the transmission mechanism includes a drive gear fixedly connected to the output end of the servo motor, a driven gear meshing with the outer side of the drive gear, and one side of both the driven gear and the drive gear being fixed to a set of crushing rollers. The reciprocating motion mechanism includes a connecting frame fixedly connected to one end of a connecting rod, a lever slidably connected inside the connecting frame, a lever block fixedly connected to one end of the lever, a drive motor fixedly connected to one end of the lever, the bottom of the drive motor being mounted on one side of the machine body via a mounting plate, and a screen fixedly connected to the bottom of the screening frame.

[0008] Furthermore, the outer side of the connecting rod is slidably connected to the machine body, the outer side of the top block is slidably connected to the fixed plate, the adjusting mechanism includes a movable plate fixedly connected to the bottom of the top block, a hydraulic rod fixedly connected to the bottom of the movable plate, the bottom of the hydraulic rod being fixed to the machine body, the guiding mechanism includes a fixed rod a fixedly connected to the top of the fixed plate, and guide grooves for the fixed rod a to slide are provided on both sides of the screening frame.

[0009] Furthermore, a fixed frame is fixedly connected to the top of the screening frame, and a fixed rod b is slidably connected inside the fixed frame. A material distribution plate is fixedly connected to one end of the fixed rod b, and the middle parts of both sides of the material distribution plate are movably connected to the machine body through connecting shafts and bearings.

[0010] Furthermore, two sets of the fixing frame and fixing rod b are provided, and they are symmetrically distributed about the transverse center line of the material distribution plate.

[0011] Furthermore, a baffle is movably connected to the side of the machine body away from the servo motor via a hinge. A groove is provided on one side of the baffle, and the groove engages with the protrusion. A limit plate is fixedly connected to one side of the protrusion, and one end of the limit plate is movably connected to the machine body via a rotating shaft. The protrusion is made of rubber.

[0012] Furthermore, the protrusion is semi-circular in shape, and the limiting plate is rectangular in shape.

[0013] The beneficial effects of this utility model are as follows: This waste circuit board recycling device drives a reciprocating motion mechanism by starting a drive motor, causing the screening frame to move. When the screening frame moves, the wavy guide grooves on both sides will contact the fixed rod a, thus oscillating. In this way, the screening frame can oscillate in two directions. When the screening frame moves, the bottom support legs will contact the raised rubber sleeve through ball bearings, thus vibrating up and down, thereby further improving the screening speed. When the weight, size, or other parameters of the circuit board fragments change, the hydraulic rod can be activated to push the moving plate to move, causing the amplitude of the rubber sleeve to change. At this time, the amplitude of the vibration of the screening frame during reciprocating movement will also change accordingly, so that the denser circuit board fragments can also move vigorously in the screening frame, ensuring the screening effect. When the screening frame reciprocates, the fixed frame will drive the fixed rod b and the material distribution plate to swing, guiding the crushed fragments so that they fall evenly into the screen. In this way, the above operations can facilitate the rapid screening of circuit board fragments. Attached Figure Description

[0024] Please see Figures 1-3 This utility model provides a technical solution: a waste circuit board recycling device, including a body 1 and a screening frame 6. A servo motor 2 is installed on one side of the body 1, and a transmission mechanism is provided on one side of the servo motor 2. Two sets of crushing rollers 5 are movably connected inside the body 1 through bearings.

[0025] A screening frame 6 is provided in the middle of the machine body 1. Multiple sets of support legs 7 are fixed to the bottom of the screening frame 6, and a fixed plate 8 is connected to the bottom of the support legs 7 by ball bearings. One side of the fixed plate 8 is welded and fixed to the inner wall of the machine body 1. Both ends of the screening frame 6 are slidably connected to connecting blocks 9 by first sliders. One side of the connecting blocks 9 is slidably connected to a connecting rod 10 by a second slider. One end of the connecting rod 10 is provided with a reciprocating motion mechanism. Multiple sets of rubber sleeves 15 are fixedly connected to the top of the fixed plate 8. The bottom of the rubber sleeves 15 abuts against a top block 16. The bottom of the top block 16 is provided with an adjustment mechanism. Guide mechanisms are provided on both sides of the screening frame 6. The transmission mechanism includes a drive gear 3 fixedly connected to the output end of the servo motor 2. A driven gear 4 is meshed with the outer side of the drive gear 3. One side of both the driven gear 4 and the drive gear 3 is fixed to a set of crushing rollers 5. The reciprocating motion mechanism includes a connecting frame 11 fixedly connected to one end of the connecting rod 10. A lever 12 is slidably connected inside the connecting frame 11. One end of the 2 is fixedly connected to a lever 13, and one end of the lever 13 is fixedly connected to a drive motor 14. The bottom of the drive motor 14 is mounted on one side of the machine body 1 via a mounting plate. The bottom of the screening frame 6 is fixedly connected to a screen 21. The outer side of the connecting rod 10 is slidably connected to the machine body 1, and the outer side of the top block 16 is slidably connected to the fixed plate 8. The adjustment mechanism includes a moving plate 17 fixedly connected to the bottom of the top block 16. The bottom of the moving plate 17 is fixedly connected to a hydraulic rod 18. The bottom of the hydraulic rod 18 is fixed to the machine body 1. The guide mechanism includes a fixed rod a19 fixedly connected to the top of the fixed plate 8. Guide grooves 20 for the fixed rod a19 to slide are provided on both sides of the screening frame 6. Since the connecting block 9 is slidably connected to the screening frame 6 via a first slider, and the connecting block 9 is slidably connected to the connecting rod 10 via a second slider, the screening frame 6 will not interfere with the connecting rod 10 when moving up and down or laterally. The connecting rod 10 can drive the screening frame 6 to move longitudinally back and forth.

[0026] Please see Figure 1 and Figure 3 A fixed frame 22 is fixedly connected to the top of the screening frame 6. A fixed rod b23 is slidably connected inside the fixed frame 22. A material distribution plate 24 is fixedly connected to one end of the fixed rod b23. The middle of both sides of the material distribution plate 24 is movably connected to the machine body 1 through a connecting shaft and a bearing. The fixed frame 22 has a through groove that matches the fixed rod b23. The fixed frame 22 and the fixed rod b23 form a sliding structure. There are two sets of fixed frames 22 and fixed rods b23, and they are symmetrically distributed about the transverse center line of the material distribution plate 24. The fixed frame 22 can move the fixed rod b23 through the through groove to drive the material distribution plate 24 to swing, thereby uniformly guiding the circuit board fragments falling from the top.

[0027] Please see Figure 2 , Figure 3 and Figure 7A baffle 27 is movably connected to the side of the machine body 1 away from the servo motor 2 via a hinge. A groove is provided on one side of the baffle 27, and the groove engages with the protrusion 26. A limit plate 25 is fixedly connected to one side of the protrusion 26. One end of the limit plate 25 is movably connected to the machine body 1 via a rotating shaft. The protrusion 26 is made of rubber. The limit plate 25 forms a rotating structure with the machine body 1 via the rotating shaft. The protrusion 26 is semi-circular in shape, and the limit plate 25 is rectangular in shape. The rubber protrusion 26 engages with the groove on one side of the baffle 27, thereby fixing the limit plate 25. The limit plate 25 then limits the baffle 27 to prevent it from rotating and opening.

[0028] For specific implementation details, please refer to [link / reference]. Figures 1-6 This waste circuit board recycling device requires the servo motor 2 to be activated when processing circuit boards. The servo motor 2 drives the drive gear 3 to mesh with the driven gear 4, thereby causing the two sets of crushing rollers 5 to rotate in opposite directions. The circuit board is then fed into the machine body 1 through the top feed port, so that it contacts the crushing rollers 5 and is crushed. At the same time, in order to screen the circuit board, the drive motor 14 is activated. The drive motor 14 drives the dial block 13 and the dial rod 12 to rotate, so that the dial rod 12 slides in the connecting frame 11, causing the connecting frame 11 to move back and forth. The connecting frame 11 drives the connecting rod 10 to move as well, so that the connecting rod 10 pushes the connecting block 9 and the screening frame 6 to move. When the screening frame 6 moves, the wavy guide grooves 20 on both sides will contact the fixed rod a19, thereby swinging. In this way, the screening frame 6 can perform two... The oscillation in each direction increases the movement range of the circuit board fragments on the screening frame 6, thereby increasing the screening speed. When the screening frame 6 moves, the bottom support legs 7 will contact the raised rubber sleeve 15 through the ball bearings, thereby vibrating up and down. The vibration of the screening frame 6 can make the internal circuit board fragments move more violently, thereby further increasing the screening speed and preventing the circuit board fragments from clogging on the screen 21. When the weight, size and other parameters of the circuit board fragments change, the hydraulic rod 18 can be activated to push the moving plate 17 to move. The moving plate 17 will drive multiple sets of top blocks 16 to squeeze the top rubber sleeve 15, causing its protrusion amplitude to change. At this time, the vibration amplitude of the screening frame 6 will also change accordingly when it moves back and forth, so that the denser circuit board fragments can also move violently in the screening frame 6, ensuring the screening effect.

[0029] Please see Figure 1 and Figure 3In order to ensure that the circuit board fragments crushed on the crushing roller 5 can fall evenly into the screening frame 6 and make full use of the screening frame 6, two sets of fixing frames 22 are set on the top of the screening frame 6. When the fixing frames 22 move, they will drive the fixing rod b23 to swing, and the fixing rod b23 will drive the material distribution plate 24 to swing. The swinging material distribution plate 24 will guide the crushed fragments to fall evenly into the screen 21, so that the screen 21 can screen the fragments evenly and quickly.

[0030] Please see Figure 2 , Figure 3 and Figure 7 When it is necessary to clean up the fragments left in the screening frame 6, the limiting plate 25 can be rotated. The limiting plate 25 will drive the protrusion 26 to disengage from the baffle 27. Then the baffle 27 can be rotated to open and clean up the circuit board fragments in the screening frame 6. In this way, the circuit board fragments can be quickly screened.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
