Description

Technical Field

[0001] The invention relates to the field of recycling waste containing other plastic components, and in particular to an automatic recycling and processing device for epoxy resin waste. Background Art

[0002] Epoxy resin is widely used in many industries due to its excellent mechanical properties, bonding properties and chemical stability, such as electronics, construction, coatings, adhesives, etc. When these products reach the end of their life cycle or the scraps and defective products generated during the production process, epoxy resin waste is formed.

[0003] With the advancement of science and technology, the rapid iteration of scientific and technological products has led to the replacement of many devices with weaker functions and performance, which has resulted in many printed circuit boards (PCBs) being discarded and wasted. The non-metallic part of waste printed circuit boards (PCBs), namely epoxy resin, can be recycled through a specific process and used to make epoxy flooring.

[0004] However, there are often multiple electronic components left on the discarded circuit boards. When recycling, the electronic components on the circuit boards often need to be disassembled by a disassembly machine. After disassembly, some circuit boards still have electronic components left.

[0015] Preferably, a discharge port is provided below one side of the frame, and a discharge mechanism is provided below the frame.

[0016] Technical effects and advantages of the present invention:

[0017] 1. The present invention uses a screening mechanism to screen the PCB boards to be crushed, and by limiting the spacing between the slides, the PCB boards with residual electronic components cannot pass through the slide plate and slide out along the slide plate, so that the residual electronic components can be recycled.

[0018] 2. The present invention has a plurality of movable plates protruding from the inclined plate, and the movable plates can hinder the PCB boards that are blocked and cannot fall, so that they can be staggered with the PCB boards with residual electronic components, so that the PCB boards that can fall can be crushed between the slide plates, and the movable plates can move back and forth, so that the PCB boards that can fall can move a distance with the PCB boards with residual electronic components, so that the front end of the slide plate can be kept empty, so that the subsequent PCB boards that fall can continue to fall and be crushed.

[0019] 3. The present invention can lower the slide plate when there are many PCB boards above it. The slide plate lowers so that the lifting plate lowers. The lowering of the lifting plate enables the sliding rod to approach the cam. After the cam rotates, it contacts with both the sliding rod and the lifting plate, thereby increasing the frequency of the slide plate's lifting and falling, thereby increasing the speed at which the PCB boards with residual electronic components on the slide plate slide down.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 9 In this embodiment, an automated recycling and processing device for epoxy resin waste is provided, comprising a frame 1, a conveyor belt 2 is installed on one side above the frame 1, a screening mechanism 3 is installed inside the frame 1, a discharge plate 4 is provided on one side of the frame 1 at one end of the screening mechanism 3, and a crushing mechanism 5 is installed inside the frame 1 at the screening mechanism 3; the screening mechanism 3 comprises a slide plate 31, the slide plates 31 are symmetrically slidably installed inside the frame 1 up and down, a gap is formed between the slide plates 31 for screening PCB boards, the horizontal height of the side of the slide plates 31 close to each other is lower than the side away from each other, the horizontal height of one end of the slide plates 31 is higher than the height of the other end of the slide plates 31, the slide plates 31 are slidably connected to the frame 1, an opening is provided at one end of the frame 1 at the lower end of the slide plates 31, a movable plate 33 for hindering the movement of the PCB boards is inserted into one side of the slide plates 31, and one end of the movable plate 33 passes through the slide plates 31; a pushing mechanism 6 is installed on one side of the frame 1, and the pushing mechanism 6 comprises a lifting plate 61 for lifting the slide plates 31, and one end of the lifting plate 61 is inserted into the frame 1 and is located below the slide plates 31.

[0038] When in use, the conveyor belt 2 conveys the discarded PCB boards to the inside of the frame 1, the PCB boards move to the screening mechanism 3, and fall to the crushing mechanism 5 below through the gap between the slides 31, and the falling PCB boards are crushed by the crushing mechanism 5. When there are still electronic components remaining on the PCB, the thickness of the PCB boards increases and cannot fall through the gap between the slides 31. The PCB boards with remaining electronic components move along the inclined slides 31 and slide to the outside of the frame 1, and slide along the discharge plate 4.

[0039] When the PCB board with residual electronic components is on the slide plate 31, the gap between the slide plates 31 is blocked. When the PCB board with residual electronic components does not slide away in time, the PCB board falling from the top falls to the side of the PCB board with residual electronic components and cannot fall. The falling PCB board slides along the side of the slide plate 31 together with the PCB board with residual electronic components. The slide plate 31 is provided with a movable plate 33 to block the falling PCB board sliding along the side, so that the falling PCB board is staggered with the PCB board with residual electronic components, so that it can fall through the gap between the slide plates 31.

[0040] By pushing the lifting plate 61 in the mechanism 6 up and down, the slide plate 31 is moved up and down to vibrate. The vibration of the slide plate 31 increases the falling speed of the PCB board with residual electronic components on the slide plate 31, thereby further improving the efficiency of the screening mechanism 3.

[0041] In further embodiments, see Figures 1-2 One end of the conveyor belt 2 extends into the frame 1 and is located above the screening mechanism 3 , and a support frame 21 is connected between the frame 1 and the lower part of the conveyor belt 2 .

[0042] The conveyor belt 2 is supported by the support frame 21 to ensure the stability of the conveyor belt 2 , and the PCB board is transported to the inside of the frame 1 through the conveyor belt 2 , so that the PCB board falls above the screening mechanism 3 .

[0043] In further embodiments, see Figures 3-4 A plurality of fixing rods 11 are fixedly connected to the inner walls on both sides of the frame 1, a connecting plate 32 is fixedly connected to one side of the slide plate 31, the fixing rods 11 pass through the connecting plate 32, and a spring 12 is provided on the outer side of the fixing rods 11 below the connecting plate 32.

[0044] The connecting plate 32 slides up and down on the fixing rod 11 so that the slide plate 31 can slide up and down to achieve vibration. The slide plate 31 slides up and down so as to increase the sliding speed of the PCB board with residual electronic components on the slide plate 31.

[0045] In further embodiments, see Figures 4-5 The limit blocks 13 are fixedly connected to the upper inner walls on both sides of the frame 1, one end of the limit block 13 is arc-shaped, one end of the connecting plate 32 is fixedly connected to a protrusion 35, one end of the protrusion 35 is arc-shaped near the limit block 13, and the multiple connecting plates 32 are located on the same inclined straight line, the inclination angle of the straight line is the same as the inclination angle of the two ends of the slide plate 31, and an elastic plate 34 is provided between the two sides of the connecting plate 32 and the slide plate 31.

[0046] When the slide plate 31 moves up and down, the slide plate 31 drives the connecting plate 32 to move together. The connecting plate 32 moves up and down, and the protrusion 35 at one end thereof also moves up and down. The protrusion 35 is thereby misaligned with the limit block 13. The connecting plate 32 is thereby able to shrink under the elastic action of the elastic plate 34. One end of the connecting plate 32 exceeds the side of the slide plate 31 and is thereby retracted into the inside of the connecting plate 32, so that the PCB board sliding down the inclined surface can slide down a certain distance together with the PCB board with residual electronic components, thereby allowing the slide plate 31 to be located in the falling area of ​​the conveyor belt 2 to leak out, so that the subsequent falling PCB board can continue to fall.

[0047] In further embodiments, see Figure 4 , 6 8. The pushing mechanism 6 also includes a cam 62, which is rotatably connected to one end of the frame 1. The cam 62 is located below the lifting plate 61. One end of the cam 62 is connected to a driving mechanism. One end of the lifting plate 61 extends into the interior of the frame 1 and is located below the connecting plate 32. One side of the lifting plate 61 is fixedly connected to a plurality of support plates 66.

[0048] The cam 62 is driven to rotate by the driving mechanism, and the cam 62 rotates to intermittently lift the lifting plate 61, and the slide plate 31 is lifted through the gap of the lifting plate 61 to achieve the up and down vibration of the slide plate 31, and the contact area between the lifting plate 61 and the connecting plate 32 is increased through multiple support plates 66, thereby improving the supporting capacity of the lifting plate 61.

[0049] In further embodiments, see Figure 4 , 6 7. There is a gap between the lifting plate 61 and the cam 62. Connecting blocks 63 are fixedly connected on both sides below the lifting plate 61. A sliding rod 64 is slidably connected inside the connecting block 63. One end of the sliding rod 64 is an inclined surface. One end of the frame 1 is located on one side of the sliding rod 64 and is fixedly connected to a limiting rail 65. The limiting rail 65 is tilted. One end of the inclined surface of the sliding rod 64 is located above the limiting rail 65. The other end of the sliding rod 64 is circular, and the circular end can be moved to the motion trajectory of the cam 62.

[0050] When there are more PCB boards on the connecting plate 32 and the slide plate 31, the weight of the PCB causes the connecting plate 32 and the slide plate 31 to descend, and the connecting plate 32 causes the lifting plate 61 to descend. A gap is provided between the lifting plate 61 and the cam 62, thereby providing space for the lifting plate 61 to descend. During the descent of the lifting plate 61, the connecting block 63 descends together with the lifting plate 61. When the connecting block 63 descends, the inclined surface of one end of the connecting block 63 descends along the limiting rail 65. The limiting rail 65 limits the connecting block 63 to move in the opposite direction of the cam 62. The connecting block 63 The cam 62 moves to the rotation track of the cam 62. When the cam 62 rotates and passes one end of the connecting block 63, it first pushes the connecting block 63 to rise. The connecting block 63 thereby pushes the lifting plate 61 to rise, causing the slide plate 31 to rise once. The cam 62 continues to rotate and contacts the lifting plate 61, pushing the lifting plate 61 to rise once, so that the cam 62 can make the lifting plate 61 rise during a single rotation. The slide plate 31 vibrates up and down multiple times, so that when there are more PCB boards on the slide plate 31, the vibration frequency of the slide plate 31 can be increased, thereby increasing the falling speed of the PCB boards.

[0051] In further embodiments, see Fig. 9 The crushing mechanism 5 includes a crushing roller, which is symmetrically located below the slide plate 31. One end of the crushing roller passes through the frame 1 and is fixedly connected to a pulley 51. One side of the cam 62 is fixedly connected to a pulley 67. A belt is provided on the outer side of the pulley 67 and the pulley 51. The other end of the crushing roller passes through the frame 1 and is fixedly connected to a gear 52. The gears 52 are meshed with each other.

[0052] When the cam 62 rotates, the pulley 2 67 is also driven to rotate. The rotation of the pulley 2 67 drives the pulley 1 51 to rotate through the belt. The rotation of the pulley 1 51 drives the crushing roller on one side to rotate, and the gear 52 at one end of the crushing roller rotates accordingly. The two gears 52 are meshed with each other, thereby driving the crushing roller on the other side to rotate in the opposite direction, thereby crushing the falling PCB board.

[0053] In further embodiments, see Figure 3 The end of the slide plate 31 with a lower horizontal height is spaced apart from the upper end of the discharge plate 4.

[0054] A gap is provided between the discharge plate 4 and one end of the slide plate 31, thereby ensuring space for the slide plate 31 to move up and down.

[0055] In further embodiments, see Figure 3 A discharge port is provided at the lower side of the frame 1, and a discharge mechanism is provided at the lower side of the frame 1. The discharge mechanism includes a conveyor belt, which is located below the crushing roller, so that the crushed PCB board is transported out from the inside of the frame 1 through the conveyor port.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
