Description

Technical Field

[0001] The invention relates to the field of resource recycling and environmental protection production, in particular to a dust removal device used in the process of regenerating waste circuit boards. Background Art

[0002] A circuit board is an electronic component consisting of an insulating base plate, connecting wires, and pads for assembling and welding electronic components. It is made using electronic printing technology. Conductive patterns are formed on the insulating board through etching and other processes to connect electronic components together to achieve specific functions of the circuit. With the continuous advancement of science and technology, the replacement speed of electronic equipment is getting faster and faster. When new electronic equipment is launched, old electronic equipment is often eliminated, and the circuit boards in them become waste circuit boards. The processing of waste circuit boards includes disassembly, crushing and grinding. The disassembly step can process each material more finely and improve the purity and efficiency of resource recovery. The existing disassembly is divided into manual disassembly and mechanical disassembly. Manual disassembly can identify high-value components on waste circuit boards with keen observation and rich experience. However, in the process of manual disassembly of waste circuit boards, a large amount of dust will be generated. These dusts may contain various harmful substances, such as heavy metals such as lead, mercury, cadmium, and chemicals such as flame retardants. Therefore, a dust removal device used in the recycling process of waste circuit boards is needed to collect and treat dust to protect the health of operators.

[0003] There are certain defects in the use of a dust removal device used in the recycling process of waste circuit boards: since small vacuum cleaners and dust hoods are usually used for dust removal when waste circuit boards are manually disassembled, their sizes are relatively fixed. For larger waste circuit boards, the dust hood may not be able to completely cover their surfaces, resulting in dust in some areas not being effectively sucked in. For smaller circuit boards, the dust inlet may be too large, and the suction force is dispersed, making it impossible to concentrate and effectively suck away the dust. Both cannot be flexibly adjusted according to the size and shape of the circuit board, thereby reducing the dust removal effect.

[0004] Therefore, it is necessary to propose a dust removal device for use in the recycling process of waste circuit boards to solve the above technical problems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a dust removal device for use in the recycling process of waste circuit boards, which solves the technical problems that for smaller circuit boards, the dust suction port may be too large and the suction force is dispersed, making it impossible to concentrate and effectively suck away the dust, and both cannot be flexibly adjusted according to the size and shape of the circuit board, thereby reducing the dust removal effect.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figure 1-Figure 4As shown, a dust removal device used in the recycling process of waste circuit boards includes a manual processing frame 1, a vacuum cleaner 12 is arranged on one side of the manual processing frame 1, a vacuum tube 13 is plugged and connected to the output end of the vacuum cleaner 12, a vacuum hood 14 is arranged at one end of the vacuum tube 13 away from the vacuum cleaner 12, and a disassembly table 11 is arranged at one end of the manual processing frame 1 and below the vacuum hood 14;

[0037] The vacuum cleaner 12 is connected to the dust hood 14 through the dust suction pipe 13. When the vacuum cleaner 12 is started, suction is generated to suck the dust generated during the disassembly of the waste circuit boards into the dust suction hood 14, and then enter the vacuum cleaner 12 through the dust suction pipe 13 for collection and treatment, thereby achieving the purpose of dust removal during the recycling process of the waste circuit boards, providing a relatively clean working environment for the staff, and reducing the harm of dust to human health and the pollution to the environment;

[0038] The limiting block 15 is disposed on the top surface of the disassembling platform 11 and is used to limit an end surface of the waste circuit board.

[0039] It should be noted that, during the recycling process of the waste circuit boards, the waste circuit boards are placed at a specific position on the disassembly table 11, and the limit block 15 limits the front end surface of the waste circuit boards to ensure that the position of the waste circuit boards is relatively fixed during the disassembly process, which is convenient for the subsequent dust collection operation;

[0040] The first adjusting component 2 is arranged on one side of the dust hood 14 and is used to adjust the size of the opening of the dust hood 14. The first adjusting component 2 includes a dust-proof elastic cloth 21 arranged at the open end of the dust hood 14. The dust-proof elastic cloth 21 is in a loop-shaped structure. Sleeves 22 are arranged on the left and right ends of the dust-proof elastic cloth 21. A movable rod 23 is slidably connected to the inner side of the sleeve 22. The left and right ends of the dust-proof elastic cloth 21 are arranged on the sleeve 22 and the movable rod 23. A fixed block 24 is installed on the opposite side of one end of the two movable rods 23 away from the sleeve 22. A telescopic plate 25 is connected between the opposite sides of the two fixed blocks 24 through a slide rail. A symmetrically arranged support rod 26 is clamped and installed at the rear end of the disassembly platform 11. An adjusting block 27 is clamped and installed on one side of the support rod 26. A cross-shaped slide groove is opened inside the adjusting block 27. A slider 28 is slidably connected in the slide groove. One end of the sleeve 22 is arranged at the front end of the slider 28.

[0041] It should be noted that, according to the size of the waste circuit board, the adjusting slider 28 moves in the cross-shaped slide groove inside the adjusting block 27, and the movement of the slider 28 drives the sleeve 22 and the movable rod 23 to move relative to each other. Since the sleeve 22 and the movable rod 23 are provided with dust-proof elastic cloth 21, when the two move relative to each other, the dust-proof elastic cloth 21 expands from both sides, so that the size of the opening of the dust cover 14 is increased, so that the waste circuit board of larger size can be better covered, and at this time, the left and right end surfaces of the waste circuit board are limited;

[0042] At the same time, between the fixed blocks 24 installed on the opposite side of the end of the two movable rods 23 away from the sleeve 22, a telescopic plate 25 is connected through a slide rail. As the dust-proof elastic cloth 21 expands, the telescopic plate 25 is extended under the action of the fixed blocks 24 on both sides to further adapt to the size change of the waste circuit board. The two movable rods 23 can also be driven to slide along the inside of the sleeve 22 on the telescopic plate 25, and the front end surface of the waste circuit board is limited at this time to ensure that the size of the opening of the dust cover 14 perfectly matches the actual size of the waste circuit board.

[0043] The present invention can flexibly adjust the opening size of the dust hood 14 according to the waste circuit boards of different sizes through the first adjustment component 2. Regardless of whether the waste circuit boards are of larger or smaller sizes, it can ensure that the dust hood 14 covers their surfaces as completely as possible, thereby improving the adaptability of the dust removal device and meeting the dust removal needs of circuit boards of various sizes during the recycling process of waste circuit boards.

[0044] like Figure 5-Figure 6 As shown, a limiting groove 220 is provided at the top of the sleeve 22, a locking groove 2201 is provided at the end of the limiting groove 220 away from the dustproof elastic cloth 21, and a side groove is provided at the end of the locking groove 2201 close to the limiting groove 220. There is at least one locking groove 2201, and the limiting groove 220 and the locking groove 2201 are connected. A locking block 29 is installed at the end of the movable rod 23 close to the sleeve 22, and the locking block 29 is inserted into one of the locking grooves 2201. An expansion spring 2202 fixedly connected to the movable rod 23 is installed inside the sleeve 22.

[0045] It should be noted that when the opening size of the dust hood 14 needs to be adjusted, the movable rod 23 is manually driven on the telescopic plate 25 to slide along the inside of the sleeve 22. When the movable rod 23 needs to be fixed, the locking block 29 at one end of the movable rod 23 slides in the limiting groove 220 at the top of the sleeve 22, and the movable rod 23 is pressed into the inside of the sleeve 22. After the movable rod 23 moves to the specified position, the locking block 29 at one end of the movable rod 23 is pushed into the locking groove 2201 at the specified position for insertion. The locking block 29 can be more firmly fixed in the locking groove 2201 by releasing the elastic force of the expansion spring 2202.

[0046] According to the present invention, the operator can adjust the position of the movable rod 23 and fix it by simple pressing and sliding actions without using complicated tools or performing cumbersome operating steps, thereby greatly improving the convenience of operation and work efficiency. At the same time, it prevents the dust-proof elastic cloth 21 from causing the movable rod 23 to be offset on the sleeve 22 due to its own elastic action, thereby causing inaccurate adjustment of the opening of the dust hood 14.

[0047] like Figure 2 , Figure 4 and Figure 7As shown, a driving assembly 211 for driving the two sliders 28 to move synchronously relative to each other is provided on the disassembly platform 11, and the driving assembly 211 includes a connecting rod 212 that is clamped and installed on the rear end of the slider 28, and a first rack plate 213 is installed at one end of the connecting rod 212 located on the right, and a second rack plate 214 is installed at one end of the connecting rod 212 located on the left. The top of the manual processing frame 1 is rotatably connected to a transmission gear 215 that meshes with the first rack plate 213 and the second rack plate 214, and the bottom of the disassembly platform 11 is slidably connected to a driving rack plate 216 that meshes with the transmission gear 215, and the driving rack plate 216 is located above the first rack plate 213 and the second rack plate 214, and the front end of the disassembly platform 11 is slidably connected to a driving plate 217 that is fixedly connected to the driving rack plate 216, and a circular hole is opened at the front end of the driving plate 217.

[0048] It should be noted that the operator inserts a finger into the round hole at the front end of the driving plate 217, and then pushes or pulls the driving plate 217. Since the driving plate 217 is fixedly connected to the driving rack plate 216, the movement of the driving plate 217 drives the driving rack plate 216 to slide at the bottom of the disassembly table 11, and the sliding of the driving rack plate 216 meshes with the transmission gear 215, thereby rotating the transmission gear 215. The transmission gear 215 is simultaneously meshed with the first rack plate 213 and the second rack plate 214. When the transmission gear 215 rotates, it drives the first rack plate 213 and the second rack plate 214 to move relative to or away from each other. The first rack plate 213 and the second rack plate 214 are respectively The first rack plate 213 and the second rack plate 214 are connected to the slider 28 through a connecting rod 212, so the movement of the two sliders 28 drives the two sliders 28 to move synchronously relative to or away from each other in the slide groove of the adjustment block 27. The relative or away movement of the sliders 28 drives the dust-proof elastic cloth 21 to expand or contract rapidly from both sides through structures such as the sleeve 22 and the movable rod 23, thereby adjusting the opening size of the dust hood 14. The present invention can achieve the synchronous relative movement of the two sliders 28 by setting a driving component 211, ensuring that the expansion or contraction of the left and right sides of the dust-proof elastic cloth 21 is uniform, thereby making the opening size adjustment of the dust hood 14 more accurate and rapid, and improving the convenience and efficiency of adjustment.

[0049] like Figure 3 and Figure 8 As shown, a groove 2170 is provided on the inner side of the driving plate 217 extending into the disassembly platform 11, and a telescopic spring rod 2171 is installed on the inner cavity side of the driving plate 217 of the disassembly platform 11. There is at least one telescopic spring rod 2171, and the moving end of the telescopic spring rod 2171 is rotatably connected to an extrusion wheel 2172, which is tightly attached to the inner side of the groove 2170.

[0050] It should be noted that, after the operator has adjusted the opening size of the dust hood 14, the driving plate 217 is released. At this time, the groove 2170 on the inner side of the driving plate 217 interacts with the telescopic spring rod 2171 on one side of the inner cavity of the disassembly table 11. Under the elastic restoring force of the telescopic spring rod 2171, the extrusion wheel 2172 generates an extrusion force on the driving plate 217. The extrusion force of the extrusion wheel 2172 on the driving plate 217 is also transmitted to the slider 28, the sleeve 22 and other components through the entire transmission system, so as to prevent the dustproof elastic cloth 21 from shrinking due to its own elasticity, thereby ensuring that the opening size of the dust hood 14 remains stable.

[0051] It is worth noting that when the dustproof elastic cloth 21 has a tendency to shrink, the shrinkage force will drive the first rack plate 213 on the right to move, but since the first rack plate 213 is meshed with the transmission gear 215, and the transmission gear 215 is meshed with the other second rack plate 214, a mutually restraining system is formed. When the shrinkage force acts on the first rack plate 213, the second rack plate 214 or the driving rack plate 216 and the transmission gear 215 will generate reverse resistance to prevent its movement, thereby preventing the dustproof elastic cloth 21 from shrinking. Similarly, the second rack plate 214 and the driving rack plate 216 on the left will also play a role in preventing shrinkage in this system. Through the meshing structure, the first rack plate 213, the transmission gear 215 and the second rack plate 214 are restrained from each other, and further jointly resist the shrinkage force of the dustproof elastic cloth 21.

[0052] like Figure 7 As shown, laser lamps 221 are installed at the bottom of the sleeves 22 and the movable rod 23 at the left and right ends, and the area illuminated by each set of laser lamps 221 is larger than the expansion area of ​​the dustproof elastic cloth 21.

[0053] It should be noted that when the opening size of the dust hood 14 is adjusted, as the sleeve 22 and the movable rod 23 move, the laser light 221 also moves accordingly. The laser light 221 can form a larger illumination range around the waste circuit board, providing a visual reference for the operator, so that the relative position of the dust-proof elastic cloth 21 and the waste circuit board can be more accurately judged when adjusting the opening size of the dust hood 14.

[0054] like Figure 5-Figure 6As shown, the front ends of the two sliders 28 are clamped and installed with ear seats 231, the rear end of the sleeve 22 is rotatably connected to the ear seats 231 through a rotating shaft, and the end of the ear seat 231 away from the dustproof elastic cloth 21 is rotatably connected to an angle adjustment block 232 fixedly connected to the sleeve 22, and the top opposite sides of the two angle adjustment blocks 232 are clamped and installed with matching rods 233, and the opposite ends of the two matching rods 233 are fixedly connected to the dust cover 14, and the top of the slider 28 is clamped and installed with a limited frame member 234, and the limited frame member 234 is an arc-shaped hollow structure. The end of the angle adjustment block 232 close to the dustproof elastic cloth 21 is equipped with a limit seat 235 which is slidably connected to the inside of the limit frame member 234. The top of the limit frame member 234 is evenly provided with arc grooves 236. One end of the angle adjustment block 232 located on the left side and directly above the limit seat 235 is rotatably connected with an angle adjustment plate 237. The rear end of the angle adjustment plate 237 is equipped with a socket which is inserted into one of the arc grooves 236. The inside of the limit frame member 234 is equipped with a curved spring rod 238 which is slidably connected to the limit seat 235.

[0055] It should be noted that when the operator needs to adjust the angle of the dust hood 14 for the convenience of processing, the operator drives the angle adjustment plate 237 to push the rear end so that the socket is disengaged from the arc groove 236 where it is currently located. At this time, the angle adjustment plate 237 is connected to the angle adjustment block 232. As the angle adjustment plate 237 moves, the angle adjustment block 232 starts to rotate. When the angle adjustment block 232 rotates, it will synchronously drive the sleeve 22 and the dust hood 14 to rotate synchronously. The operator rotates the angle adjustment block 232 to different angles according to actual processing requirements, thereby adjusting the angle of the dust hood 14 to make it better adapt to the processing position of the waste circuit board. After the dust hood 14 is rotated to the specified position, the operator drives the socket to enter another arc groove 236 at the top of the limiting frame member 234 through the angle adjustment plate 237 again. At this time, the cooperation between the socket and the arc groove 236 plays a role in fixing the position of the angle adjustment block 232.

[0056] When the vacuum cleaner 12 generates vibration during operation, the curved spring rod 238 can absorb the vibration energy, prevent the angle adjustment block 232 from accidentally moving, and ensure that the angle of the dust hood 14 remains stable. By adjusting the angle of the dust hood 14, the dust hood 14 can be more accurately aligned with the area where dust is generated on the waste circuit board, thereby improving the dust collection effect, ensuring that the dust can be sucked into the dust hood 14 in a timely and effective manner, and reducing the harm of dust to the environment and the operator.

[0057] like Figure 9-10As shown, the second adjustment component 3 is arranged inside the dust hood 14 and is used to adjust the size of the air duct in the dust hood 14. The second adjustment component 3 includes a rectangular frame 31 arranged above the dust-proof elastic cloth 21. The rectangular frame 31 is snap-fitted and installed below the dust hood 14. The left and right ends of the rectangular frame 31 are slidably connected with a first adjustment plate 32. The front end of the rectangular frame 31 is slidably connected with a second adjustment plate 33. The second adjustment plate 33 is arranged above the first adjustment plate 32. The first adjustment plate 32 and the second adjustment plate 33 extend outward from the outer ends of the rectangular frame 31 and fixed plates are installed above the two ends. 34, a spring rod 35 slidably connected to the fixed plate 34 is clamped and installed at one end of the rectangular frame 31 located on the fixed plate 34, rollers 36 are installed at the middle of the left and right ends of the rectangular frame 31 and the left and right ends of the front end of the rectangular frame 31, and a steel wire rope 37 that can slide through the roller 36 is installed below the first adjustment plate 32 and the second adjustment plate 33, and one end of the steel wire rope 37 located at the left and right ends away from the first adjustment plate 32 is fixedly connected to the top of the second adjustment plate 33, and one end of the steel wire rope 37 located at the front end away from the second adjustment plate 33 is fixedly connected above the fixed block 24.

[0058] It should be noted that when the first adjustment component 2 is adjusted, the movement of the sleeve 22 will apply tension to the wire rope 37. As the tension is generated, the spring rod 35 is stretched, and the wire rope 37 begins to slide under the action of the tension with the help of the roller 36. Specifically, the wire rope 37 drives the first adjustment plate 32 to move outward from the inside of the rectangular frame 31 through the action of the roller 36. At this time, the air duct area inside the rectangular frame 31 is expanded due to the outward movement of the first adjustment plate 32.

[0059] On the contrary, when the sleeves 22 at the left and right ends move toward the dustproof elastic cloth 21, the spring potential energy of the spring rod 35 is released, and under the contraction force of the spring rod 35, the first adjustment plate 32 is pushed to move toward the inside of the rectangular frame 31 through the fixing plate 34, thereby reducing the air duct area inside the rectangular frame 31;

[0060] The working principle of the second adjustment plate 33 is the same as that of the first adjustment plate 32. When processing waste circuit boards of larger sizes, the sleeve 22 moves outward, the air duct expands, the dust suction capacity is enhanced, and the effective suction of dust is ensured. When processing circuit boards of smaller sizes, the sleeve 22 is close to the dustproof elastic cloth 21, the air duct shrinks, and the suction force is avoided from being dispersed, thereby improving the dust suction efficiency.

[0061] like Figure 10-11As shown, a rotating disk 321 is rotatably connected to the front and rear ends of the rectangular frame 31 and located below the second adjustment plate 33, a fan 322 fixedly connected to the rotating disk 321 is rotatably connected to the inner front and rear ends of the rectangular frame 31, and a protrusion 323 in a ring array is installed at one end of the rotating disk 321 facing away from the fan 322, a fixing frame 324 is clamped and installed at the left and right ends of the rectangular frame 31 located on the rotating disk 321, a beating seat 325 is rotatably connected below the fixing frame 324, and a rotating rod 327 fixedly connected to the beating seat 325 is rotatably connected to one end of the fixing frame 324 close to the rotating disk 321, the rotating rod 327 is L-shaped, and the horizontal end of the rotating rod 327 is tightly attached to the protrusion 323, and a rotating column 328 is rotatably connected to one side of the fixing frame 324 and located below the rotating rod 327, and a compression spring 329 is installed between one end of the rotating column 328 and the vertical end of the rotating rod 327.

[0062] It should be noted that when the vacuum cleaner 12 is working, wind is generated in the rectangular frame 31. Since the fan 322 is rotatably connected to the front and rear ends of the inner side of the rectangular frame 31, and the fan 322 is fixedly connected to the rotating disk 321, the fan 322 starts to rotate under the action of wind, thereby driving the rotating disk 321 and the protrusions 323 to rotate synchronously. The protrusions 323 in a circular array on the rotating disk 321 will contact the horizontal end of the rotating rod 327 during the rotation process. When the protrusion 323 contacts the rotating rod 327, the protrusion 323 drives the rotating rod 327 to rotate a certain angle, and the rotation of the rotating rod 327 drives the beating seat 325 to move. At the same time, a compression spring 329 is installed between the vertical end of the rotating rod 327 and the rotating column 328. When the rotating rod 327 rotates, the rotating column 328 is stretched, so that the compression spring 329 is stretched to store elastic potential energy. At this time, the beating seat 325 is away from the dustproof elastic cloth 21, and when the protrusion 323 is separated from the rotating rod 327 as the rotating disk 321 continues to rotate, the compression spring 329 releases its elastic force. Under the restoring force of the compression spring 329, the rotating rod 327 is reset, driving the beating seat 325 to move in the opposite direction. At this time, the beating seat 325 drives the beating member 326 to quickly beat the dust on the inner surface of the dustproof elastic cloth 21;

[0063] During the recycling process of the waste circuit boards, the vacuum cleaner 12 vacuums dust through the dust cover 14 and the rectangular frame 31, which easily causes dust to accumulate on the dustproof elastic cloth 21. The periodic beating action of the beating seat 325 can prevent dust from clogging the dustproof elastic cloth 21, maintain the air permeability of the dustproof elastic cloth 21, and ensure that the vacuuming effect is not affected. In particular, for fine dust, the beating action can loosen it and make it easier to be sucked into the vacuum cleaner 12, thereby improving the dust removal efficiency.

[0064] like Figure 4As shown, the left and right ends of the dustproof elastic cloth 21 are respectively connected to the sleeve 22 and the movable rod 23, the front end of the dustproof elastic cloth 21 and the telescopic plate 25, and the top of the dustproof elastic cloth 21 and the rectangular frame 31 by Velcro.

[0065] It should be noted that the Velcro is composed of a sub-surface with fine soft fibers on one side and a main surface with harder hooked hairs on the other side. When the dust-proof elastic cloth 21 needs to be connected with the sleeve 22, the movable rod 23, the telescopic plate 25 and the rectangular frame 31, it is only necessary to fit the corresponding parts together, and the fibers of the sub-surface will be hooked with the hooked hairs of the main surface to achieve a quick connection. If the dust-proof elastic cloth 21 needs to be adjusted or replaced, it can be easily separated from the connection part and then re-attached as needed. It has high flexibility.

[0066] The working principle of the present invention is that the dust removal device used in the recycling process of waste circuit boards is used to place the waste circuit boards at a specific position on the disassembly table 11 during the recycling process of the waste circuit boards. The limit block 15 limits the front end surface of the waste circuit boards to ensure that the position of the waste circuit boards is relatively fixed during the disassembly process, which is convenient for subsequent dust collection operations. According to the size of the waste circuit boards, the adjustment slider 28 moves in the cross-shaped slide groove inside the adjustment block 27. The movement of the slider 28 drives the sleeve 22 and the movable rod 23 to move relative to each other. Since the sleeve 22 and the movable rod 23 are provided with dust-proof elastic cloth 21, when the two move relative to each other, the dust-proof elastic cloth 21 expands from both sides, so that the dust collection cover The size of the opening of 14 is increased, which can better cover the waste circuit boards of larger sizes. At this time, the left and right end surfaces of the waste circuit boards are limited. At the same time, between the fixed blocks 24 installed on the opposite sides of the ends of the two movable rods 23 away from the sleeve 22, a telescopic plate 25 is connected through a slide rail. As the dust-proof elastic cloth 21 expands, the telescopic plate 25 extends under the action of the fixed blocks 24 on both sides, further adapting to the size changes of the waste circuit boards. The two movable rods 23 can also be driven on the telescopic plate 25 to slide along the inside of the sleeve 22, which limits the front end surface of the waste circuit board to ensure that the size of the opening of the dust cover 14 perfectly matches the actual size of the waste circuit board.

[0067] The operator inserts a finger into the round hole at the front end of the driving plate 217, and then pushes or pulls the driving plate 217. Since the driving plate 217 is fixedly connected to the driving rack plate 216, the movement of the driving plate 217 drives the driving rack plate 216 to slide at the bottom of the disassembly table 11. The sliding of the driving rack plate 216 meshes with the transmission gear 215, thereby rotating the transmission gear 215. The transmission gear 215 is simultaneously meshed with the first rack plate 213 and the second rack plate 214. When the transmission gear 215 rotates, it drives the first rack plate 213 and the second rack plate 214 to rotate. The strip plate 213 and the second rack plate 214 move relative to or away from each other. The first rack plate 213 and the second rack plate 214 are connected to the slider 28 via the connecting rod 212, respectively. Therefore, the movement of the first rack plate 213 and the second rack plate 214 drives the two sliders 28 to move relative to or away from each other synchronously in the slide groove of the adjustment block 27. The relative or away movement of the sliders 28 drives the dustproof elastic cloth 21 to expand or contract rapidly from both sides through the sleeve 22, the movable rod 23 and other structures, thereby adjusting the opening size of the dust hood 14.

[0068] When the first adjustment component 2 is adjusted, the movement of its sleeve 22 will apply tension to the wire rope 37. As the tension is generated, the spring rod 35 is stretched. Under the action of the tension, the wire rope 37 begins to slide with the help of the roller 36. Specifically, the wire rope 37 drives the first adjustment plate 32 to move outward from the inside of the rectangular frame 31 through the action of the roller 36. At this time, the air duct area inside the rectangular frame 31 is expanded due to the outward movement of the first adjustment plate 32. Conversely, when the sleeves 22 at the left and right ends move toward the direction close to the dustproof elastic cloth 21, the spring rod 35 is stretched. 5 is released, and under the action of the contraction force of the spring rod 35, the first adjustment plate 32 is pushed to move toward the inside of the rectangular frame 31 through the fixing plate 34, so that the air duct area inside the rectangular frame 31 is reduced. For the second adjustment plate 33, its working principle is the same as that of the first adjustment plate 32. When processing waste circuit boards of larger sizes, the sleeve 22 moves outward, the air duct is expanded, the dust collection capacity is enhanced, and the dust is effectively sucked in. When processing circuit boards of smaller sizes, the sleeve 22 is close to the dustproof elastic cloth 21, the air duct is reduced, the suction force is avoided from being dispersed, and the dust collection efficiency is improved.
