Description

Technical Field

[0001] The present invention relates to the technical field of circular saw cutting equipment, and specifically to a steel structure cutting equipment for building material processing. Background Art

[0002] The steel structure circular saw cutting equipment is a key equipment used to process steel structure materials in the building material processing field. Its structure is centered around a high-speed rotating circular saw blade. The saw blade is usually made of high-hardness alloy material, and its edge is processed by special processes such as quenching and coating, which improves the wear resistance and sharpness of the saw blade. The power system of the circular saw cutting equipment is mainly composed of a motor. The motor provides the rotating power for the saw blade. When the saw blade contacts the steel structure material, the cutting force generated by the rotation of the saw blade cuts into the material. With the movement of the equipment workbench, linear or curved cutting of the steel structure is achieved. It is easy to operate and has high cutting efficiency, and is widely used in the building material processing field.

[0003] In the building material processing field, the existing steel structure circular saw cutting machines are usually equipped with a water spraying device at the blade to cool the blade and suppress the flying of debris through continuous water spraying, and the debris is collected by a dust collection box. However, when cutting large-area steel plates, this technical solution has drawbacks: to collect the debris generated by the cutting of the steel plate, the volume of the dust collection box needs to be correspondingly enlarged, which leads to an increase in its internal space and is difficult to clean. Moreover, the currently commonly used manual cleaning method requires the cleaning personnel to wear protective clothing, wear a respirator, and carry a small electric dust suction device to enter the dust collection box for cleaning work. The inner wall of the dust collection box forms a smooth wear surface due to long-term impact of metal debris, and the internal lighting is insufficient and the ground is slippery, resulting in the cleaning personnel being prone to losing balance during movement and having safety accidents such as bumps and slips, posing a safety risk, and urgent technological innovation is needed to solve such problems.

[0017] (III) Beneficial effects

[0018] The present invention provides a steel structure cutting device for building material processing, having the following beneficial effects:

[0019] (I). In this cutting device, through the dust collection component, during the process of the cutting mechanism moving for cutting, the impurities and metal chips generated are washed by the spraying device to form a mixture of metal chips and sewage, which then falls on the dust collection plate. During the movement of the cutting mechanism, the linkage component drives the flipping component to undergo corresponding displacements, causing the cleaning brush to undergo corresponding displacements, so that the sewage mixture moves to the right close to the dust collection box, thereby achieving the purpose of cleaning.

[0020] (II). In this cutting device, through the linkage component, when the driving frame moves under the drive of the fourth motor through the threaded transmission of the second screw rod and the second screw sleeve, the extension rod fixed to the side wall of the driving frame moves accordingly. At this time, the second sliding sleeve slidably connected to the extension rod slides on its side wall due to the displacement of the extension rod. The second sliding sleeve drives the first sliding sleeve to slide on the side plate through the connecting rod. The linkage component enables the flipping component to move along with the movement of the cutting mechanism, so that during the movement of the cutting mechanism, the cleaning brush can cooperate with the cutting mechanism to clean the dust collection plate, improving the cleaning effect of the dust collection component.

[0021] (III). In this cutting device, through the feeding device, when the push plate pushes the steel plate, the inclined surfaces at both ends thereof are separated from the abutting plate, and the first elastic telescopic rod releases elastic potential energy to push the clamping plate, so that the limiting strip is clamped into the clamping groove to fix the feeding belt, avoiding the shaking of the steel plate during pushing and improving the feeding stability. After the pushing is completed, the push plate moves backward, and its inclined surface presses the abutting plate, driving the clamping plate to slide against the elastic force, so that the clamping groove is separated from the limiting strip, leaving a feeding space. After the push plate resets, the elastic telescopic rod stores potential energy and repeats the above actions when pushing next time to ensure stable feeding and accurate delivery of the steel plate to the conveying device.

[0022] (4) For this cutting device, through the spraying device, when the front end of the steel plate reaches the limiting component, the steel plate first contacts the inclined rod. As the steel plate continues to move forward, it will push the inclined rod and the limiting rod connected thereto to move to both sides. At this time, the second elastic telescopic rod is compressed. When both sides of the steel plate are in contact with the limiting rod, the second elastic telescopic rod releases elastic potential energy, causing the limiting rod to tightly fit on both sides of the steel plate. Its function is that the limiting component can limit the lateral movement of the steel plate during the conveying process, reduce the cutting error caused by the deviation of the steel plate, and improve the processing quality.

[0023] (5) For this cutting device, through the spraying device, when the cutting mechanism performs cutting operations on the steel structure, the water pump is turned on; after the water pump starts, it will generate suction, transport water through the water pipe to the nozzle, and the nozzle then sprays the water in the form of spraying onto the cutting part to cool and remove dust from the cutting tool during cutting.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1: Please refer to Figures 1-5, the present invention provides a technical solution: a steel structure cutting device for building material processing, including a frame 10, a feeding device 20, a conveying device 30 fixedly connected to the side wall of the frame 10, and a driving device 40. The driving device 40 includes a driving frame 41, and the inner wall of the driving frame 41 is slidably connected to the frame 10; a cutting mechanism 50, the side wall of the cutting mechanism 50 is slidably connected to the side wall of the driving frame 41; the side wall of the feeding device 20 is fixedly connected to the side wall of the frame 10; the feeding device 20 includes a blanking wheel 21, the side walls on both sides of the blanking wheel 21 are rotatably connected to the side wall of the frame 10, a blanking belt 22 is rotatably connected to the side wall of the blanking wheel 21, a limiting strip 23 is fixedly connected to the side wall of the blanking belt 22, and a plurality of limiting strips 23 are evenly distributed along the length direction of the blanking belt 22 on the blanking belt 22. A first motor 24 is fixedly connected to the side wall of the frame 10, the output end of the first motor 24 is fixedly connected to the blanking wheel 21, a positioning plate 25 is fixedly connected to the side wall of the frame 10, a first cylinder 26 is fixedly connected to the side wall of the frame 10, and a push plate 27 is fixedly connected to the output end of the first cylinder 26; when using the feeding device 20, place the ends on both sides of each steel plate in the gaps between adjacent two limiting strips 23, and multiple steel plates can be placed at the same time. Start the first motor 24, which drives the blanking wheel 21 to rotate, and the blanking wheel 21 drives the blanking belt 22 to run. When the steel plate at the bottom of the blanking belt 22 is conveyed to the positioning plate 25, start the first cylinder 26, and the push plate 27 at its output end pushes the steel plate to the conveying device 30 for subsequent processing and pushing operations; since multiple steel plates can be placed at the same time, the operation of manually adding materials frequently is reduced, and the feeding efficiency is improved. At the same time, during the feeding process, each steel plate is separated by the limiting strips 23, avoiding the dislocation or jamming phenomenon caused by mutual extrusion and stacking between the steel plates, making the feeding process more orderly and stable.

[0037] The side walls of the frame 10 are symmetrically and slidably connected with abutting components 28. The abutting components 28 include abutting plates 281. The side walls of the abutting plates 281 are slidably connected with the inner walls of the frame 10. The side walls of the abutting plates 281 are in contact with the side walls on both sides of the push plate 27. A clamping plate 282 is fixedly connected to the side wall of the abutting plate 281. A clamping groove 283 is formed in the side wall of the clamping plate 282. A first elastic telescopic rod 284 is fixedly connected to the side wall of the frame 10. The telescopic end of the first elastic telescopic rod 284 is fixedly connected to the side wall of the clamping plate 282. Among them, the elastic element in the first elastic telescopic rod 284 is a spring, so that the first elastic telescopic rod 284 can automatically rebound. When the first cylinder 26 drives the push plate 27 to push the steel plate, the inclined surfaces at both ends of the push plate 27 are separated from the abutting plate 281, and the elastic potential energy released by the first elastic telescopic rod 284 pushes the clamping plate 282, so that the limiting strip 23 is clamped in the clamping groove 283. During the pushing process of the steel plate, the blanking belt 22 fixedly connected to the limiting strip 23 is not likely to shake, improving the stability of the feeding device 20. When the first cylinder 26 drives the push plate 27 to finish pushing the steel plate and moves backward, the inclined surfaces at both ends of the push plate 27 gradually come into contact with the inclined surfaces of the abutting plate 281 close to one end of the push plate 27. As the push plate 27 continues to move backward, the push plate 27 will squeeze the abutting plate 281, forcing the abutting plate 281 to drive the clamping plate 282 to overcome the elastic force of the first elastic telescopic rod 284 and slide along the side wall of the frame 10, so that the clamping groove 283 is separated from the limiting strip 23, leaving space for placing the steel plate next time; at the same time, when the push plate 27 finishes moving backward and resetting, the first elastic telescopic rod 284 will accumulate elastic potential energy again. When the push plate 27 pushes the steel plate next time, the elastic potential energy will be released again, making the abutting component 28 reset and clamp the limiting strip 23. In this way, it circulates continuously, continuously ensuring the stability of the feeding device 20 during the feeding process, so that each steel plate can be pushed to the conveying device 30.

[0038] The conveying device 30 includes conveying wheels 31. Connecting shafts 32 are fixedly connected to the side walls on both sides of the conveying wheels 31. The side walls of the connecting shafts 32 are rotatably connected with the inner walls of the frame 10. A toothed wheel 33 is fixedly connected to the side wall of the connecting shaft 32. A toothed belt 34 is rotatably connected to the side wall of the toothed wheel 33. A second motor 35 is fixedly connected to the side wall of the frame 10. The output end of the second motor 35 is fixedly connected to the side wall of the toothed wheel 33. When using the conveying device 30, start the second motor 35. The rotation of the second motor 35 will drive the toothed wheel 33 to rotate, drive the toothed belt 34 to move, and drive other toothed wheels 33 to rotate; the rotation of the toothed wheel 33 is transmitted to the conveying wheel 31 through the connecting shaft 32, so that multiple conveying wheels 31 rotate synchronously. The conveying device 30 can convey the steel plates sent by the feeding device 20 through multiple conveying wheels 31.

[0039] The side walls of the frame 10 are fixedly connected with a limiting component 36. The limiting component 36 includes a second elastic telescopic rod 361. The fixed end of the second elastic telescopic rod 361 is fixedly connected with the side walls on both sides of the frame 10. The telescopic end of the second elastic telescopic rod 361 is fixedly connected with a limiting rod 362. One end of the limiting rod 362 close to the feeding device 20 is fixedly connected with an inclined rod 363. During the process of the steel plate being conveyed to the conveying device 30, when the front end of the steel plate reaches the limiting component 36, the steel plate first contacts the inclined rod 363. As the steel plate continues to move forward, it will push the inclined rod 363 and the connected limiting rod 362 to move to both sides. At this time, the second elastic telescopic rod 361 is compressed. When both sides of the steel plate are in contact with the limiting rod 362, the second elastic telescopic rod 361 releases elastic potential energy, making the limiting rod 362 tightly fit on both sides of the steel plate. Its function is that the limiting component 36 can limit the lateral movement of the steel plate during the conveying process, reduce the cutting error caused by the offset of the steel plate, and improve the processing quality.

The output end of the fourth motor 47 is fixedly connected with the second screw rod 45; when it is necessary to adjust the cutting position of the cutting mechanism 50, start the fourth motor 47. Its output end drives the second screw rod 45 to rotate, making the second screw sleeve 46 slide linearly along the second screw rod 45, and then driving the driving frame 41 to move along the side wall of the frame 10, realizing the position adjustment of the cutting mechanism 50 in one direction; start the third motor 44: its output end drives the first screw rod 42 to rotate, making the first screw sleeve 43 slide linearly along the first screw rod 42, thereby driving the cutting mechanism 50 to move along the top of the driving frame 41, realizing the position adjustment of the cutting mechanism 50 in another direction; therefore, the setting of the driving device 40 facilitates the staff to control the cutting position of the cutting mechanism 50.

[0041] The cutting mechanism 50 includes a second cylinder 51. The fixed end of the second cylinder 51 is fixedly connected to the side wall of the first screw sleeve 43. The output end of the second cylinder 51 is fixedly connected with a connecting frame 52. A fifth motor 53 is fixedly connected to the side wall of the connecting frame 52. The output end of the fifth motor 53 penetrates through the connecting frame 52 and is fixedly connected with a cutting tool 54. When the steel structure needs to be cut, according to the thickness of the steel structure and the cutting requirements, start the second cylinder 51 to drive the connecting frame 52 to rise or fall, adjust the height of the cutting tool 54 to make it in a suitable cutting position. After the height of the cutting tool 54 is adjusted, start the fifth motor 53. The output end of the fifth motor 53 drives the cutting tool 54 to rotate at a high speed for cutting. The setting of the second cylinder 51 enables the height of the cutting tool 54 to be adjusted flexibly, which can adapt to steel structures with different thicknesses and cutting requirements, enhancing the adaptability of the cutting equipment.

The clamping surface of the first clamping strip 681 is clamped with the clamping surface of the second clamping strip 682; When the steel structure cutting equipment is running, the driving frame 41 drives the cutting mechanism 50 to move, and the linkage assembly 67 pushes the flipping assembly 65 to slide on the side plate 63; When the first sliding sleeve 651 slides to the left, the second clamping strip 682 on its inner wall is clamped with the first clamping strip 681 on the rotating shaft 652, and the cleaning brush 66 is suspended, preventing dust from being pushed away from the dust collection box 64 by the cleaning brush 66; The flipping claw 656 flips at the limiting groove 657 without blocking the movement of the first sliding sleeve 651 and the cleaning brush 66; When the first sliding sleeve 651 slides to the right, the flipping claw 656 contacts and abuts against the side wall of the convex block 653, rotates clockwise, drives the limiting sleeve 654 and the rotating shaft 652 to rotate, so that the first clamping strip 681 disengages from the second clamping strip 682, and the cleaning brush 66 flips to the left side of the rotating shaft 652 and abuts against the top wall of the dust collection plate 62. The cleaning brush 66 sweeps the metal debris and sewage mixture on the dust collection plate 62 into the dust collection box 64. The flipping claw 656 flips at the limiting groove 657 without blocking the movement; When the first sliding sleeve 651 slides to the left again, the flipping claw 656 rotates counterclockwise, drives the cleaning brush 66 to flip to the right side of the rotating shaft 652, and the first clamping strip 681 and the second clamping strip 682 gradually contact, abut, and undergo elastic deformation, forming a clamping again, making the cleaning brush 66 suspended and stable; Thus, during the continuous operation of the equipment, the dust collection assembly 60 forms an automatic cleaning cycle; When the cutting mechanism 50 reciprocates, the linkage assembly 67 drives the first sliding sleeve 651 to slide left and right, moving to the right for cleaning and moving to the left for resetting and fixing;The dust collecting plate 62 is elastically connected to the frame 10 through the third elastic telescopic rod 61 and is inclined downward, which is conducive to the rapid sliding of the sewage mixture into the dust collecting box 64.;

[0045] The linkage assembly 67 includes a connecting rod 671. One end of the connecting rod 671 is fixedly connected to the first sliding sleeve 651, and the other end is fixedly connected to a second sliding sleeve 672. The side walls of the driving frame 41 are symmetrically and fixedly connected with extension rods 673. The inner wall of the second sliding sleeve 672 is slidably connected to the side wall of the extension rod 673. When the driving frame 41 is driven by the fourth motor 47 and moves through the threaded transmission of the second screw rod 45 and the second nut 46, the extension rod 673 fixed to the side wall of the driving frame 41 moves accordingly. At this time, the second sliding sleeve 672 slidably connected to the extension rod 673 slides on its side wall due to the displacement of the extension rod 673. The second sliding sleeve 672 drives the first sliding sleeve 651 to slide on the side plate 63 through the connecting rod 671. When the driving frame 41 moves in the reverse direction, the second sliding sleeve 672 slides in the reverse direction along the extension rod 673, thereby driving the first sliding sleeve 651 to reset. The linkage assembly 67 converts the movement of the driving frame 41 into the sliding of the first sliding sleeve 651 on the side plate 63 through the cooperation of the connecting rod 671, the second sliding sleeve 672 and the extension rod 673, so as to realize the linkage of the movement of the flipping assembly 65 and the cutting mechanism 50, enabling the cleaning brush 66 to cooperate with the cutting mechanism 50 to clean the dust collecting plate 62 during the movement of the cutting mechanism 50, and improving the cleaning effect of the dust collecting assembly 60.

[0046] Working principle:

[0047] When in use, the cutting device mainly consists of a feeding device 20, a conveying device 30, a driving device 40, a cutting mechanism 50 and a dust collecting assembly 60. Among them, the feeding device 20 is used to push the steel plate to the conveying device 30, the conveying device 30 is used to convey the cut steel plate out of the frame 10, the driving device 40 is used to control the cutting position of the cutting mechanism 50, the cutting mechanism 50 is used to cut the steel plate, and the dust collecting assembly 60 is used to collect the dust and debris generated during the cutting process and cooperate with the driving device 40 to clean the dust and debris.

[0048] Among them, the feeding device 20 includes a feeding wheel 21, a feeding belt 22, a limiting strip 23, a first motor 24, a positioning plate 25, a first cylinder 26, and a push plate 27. When using the feeding device 20, the ends of both sides of each steel plate are placed in the gap between two adjacent limiting strips 23. Multiple steel plates can be placed at the same time. The first motor 24 is started, which drives the feeding wheel 21 to rotate, and the feeding wheel 21 drives the feeding belt 22 to run. When the steel plate at the bottom of the feeding belt 22 is transported to the positioning plate 25, the first cylinder 26 is started, and the push plate 27 at its output end pushes the steel plate to the conveying device 30 for subsequent processing and pushing operations. Since multiple steel plates can be placed at the same time, the operation of frequent manual addition of materials is reduced, and the loading speed is improved. At the same time, during the loading process, each steel plate is separated by the limiting strip 23, which avoids the misalignment or jamming caused by mutual squeezing and stacking between the steel plates, making the loading process more orderly and stable.

[0049] The abutment assembly 28 includes an abutment plate 281, a clamping plate 282, a clamping groove 283 and a first elastic telescopic rod 284. The elastic element in the first elastic telescopic rod 284 is a spring, so that the first elastic telescopic rod 284 can automatically rebound. When the first cylinder 26 drives the push plate 27 to push the steel plate, the inclined surfaces at both ends of the push plate 27 are separated from the abutment plate 281, and the elastic potential energy released by the first elastic telescopic rod 284 pushes the clamping plate 282, so that the limit bar 23 is clamped in the clamping groove 283, so that during the pushing process of the steel plate, the unloading belt 22 fixedly connected to the limit bar 23 is difficult to shake, thereby improving the stability of the feeding device 20. When the first cylinder 26 drives the push plate 27 to push the steel plate and move backward, the inclined surfaces at both ends of the push plate 27 gradually The push plate 27 contacts the inclined surface of the abutment plate 281 near one end of the push plate 27. As the push plate 27 continues to move backward, the push plate 27 will squeeze the abutment plate 281, forcing the abutment plate 281 to drive the clamping plate 282 to overcome the elastic force of the first elastic telescopic rod 284 and slide along the side wall of the frame 10, so that the clamping groove 283 is separated from the limit strip 23, leaving space for the next placement of the steel plate; at the same time, when the push plate 27 completes the backward movement and resets, the first elastic telescopic rod 284 will accumulate elastic potential energy again, waiting for the next push plate 27 to push the steel plate, and then release the elastic potential energy again, allowing the abutment assembly 28 to reset and clamp the limit strip 23, and this cycle is repeated, thereby improving the stability of the feeding device 20 during the feeding process, so that each steel plate can be pushed to the conveying device 30.

[0050] The conveying device 30 includes a conveying wheel 31, a connecting shaft 32, a toothed wheel 33, a toothed belt 34, and a second motor 35. When using the conveying device 30, the second motor 35 is started. The rotation of the second motor 35 drives the toothed wheel 33 to rotate, drives the toothed belt 34 to move, and drives a plurality of other toothed wheels 33 to rotate. The rotation of the toothed wheel 33 is transmitted to the conveying wheel 31 through the connecting shaft 32, causing a plurality of conveying wheels 31 to rotate synchronously. The conveying device 30 can convey the steel plates sent by the feeding device 20 more smoothly and efficiently through the plurality of conveying wheels 31.

[0051] The limiting component 36 includes a second elastic telescopic rod 361, a limiting rod 362, and an inclined rod 363. During the process of the steel plate being conveyed to the conveying device 30, when the front end of the steel plate reaches the limiting component 36, the steel plate first contacts the inclined rod 363. As the steel plate continues to move forward, it will push the inclined rod 363 and the connected limiting rod 362 to move to both sides. At this time, the second elastic telescopic rod 361 is compressed. When the two sides of the steel plate are in contact with the limiting rod 362, the second elastic telescopic rod 361 releases elastic potential energy, causing the limiting rod 362 to tightly fit on both sides of the steel plate. Its function is that the limiting component 36 can limit the lateral movement of the steel plate during conveying, reduce the cutting error caused by the offset of the steel plate, and improve the processing quality.

[0052] The driving device 40 includes a driving frame 41, a first screw rod 42, a first screw sleeve 43, a third motor 44, a second screw rod 45, a second screw sleeve 46, and a fourth motor 47. When it is necessary to adjust the cutting position of the cutting mechanism 50, the fourth motor 47 is started. The output end thereof drives the second screw rod 45 to rotate, causing the second screw sleeve 46 to slide linearly along the second screw rod 45, and then driving the driving frame 41 to move along the side wall of the machine frame 10, realizing the position adjustment of the cutting mechanism 50 in one direction. The third motor 44 is started: the output end thereof drives the first screw rod 42 to rotate, causing the first screw sleeve 43 to slide linearly along the first screw rod 42, thereby driving the cutting mechanism 50 to move along the top of the driving frame 41, realizing the position adjustment of the cutting mechanism 50 in another direction. Therefore, the setting of the driving device 40 facilitates the staff to control the cutting position of the cutting mechanism 50.

[0053] The cutting mechanism 50 includes a second cylinder 51, a connecting frame 52, a fifth motor 53, and a cutting tool 54. When it is necessary to cut a steel structure, according to the thickness of the steel structure and the cutting requirements, the second cylinder 51 is started to drive the connecting frame 52 to rise or fall, adjusting the height of the cutting tool 54 to make it in a suitable cutting position. After the height of the cutting tool 54 is adjusted, the fifth motor 53 is started. The output end of the fifth motor 53 drives the cutting tool 54 to rotate at a high speed for cutting. The setting of the second cylinder 51 enables the height of the cutting tool 54 to be adjusted flexibly, which can adapt to steel structures of different thicknesses and cutting requirements, enhancing the adaptability of the cutting equipment.

[0054] The spraying device 55 includes a water pump 551, a water pipe 552, and a spray head 553; when the cutting mechanism 50 performs cutting operations on the steel structure, the water pump 551 is turned on; after the water pump 551 starts, it generates suction, transports water through the water pipe 552 to the spray head 553, and the spray head 553 then sprays the water in a spraying form onto the cutting part; to cool and remove dust from the cutting knife 54 during cutting.

During the movement of the cutting mechanism 50, the linkage assembly 67 drives the flipping assembly 65 to undergo corresponding displacement, causing the cleaning brush 66 to undergo corresponding displacement. The clamping assembly 68 makes the cleaning brush 66 not easily shake during movement, causing the sewage mixture to move to the right close to the dust collection box 64, thereby achieving the purpose of cleaning.

[0056] The flipping assembly 65 includes a first sliding sleeve 651, a rotating shaft 652, a bump 653, a limiting sleeve 654, a rotating ring 655, flipping claws 656, and a limiting groove 657; when the steel structure cutting equipment is operating, the driving frame 41 drives the cutting mechanism 50 to move, and the linkage assembly 67 pushes the flipping assembly 65 to slide on the side plate 63; when the first sliding sleeve 651 slides leftward, the clamping assembly 68 makes the position between the rotating shaft 652 and the first sliding sleeve 651 relatively fixed, and the cleaning brush 66 is suspended to prevent dust from being pushed away from the dust collection box 64 by the cleaning brush 66; the flipping claws 656 flip at the limiting groove 657 without blocking the movement of the first sliding sleeve 651 and the cleaning brush 66; when the first sliding sleeve 651 slides rightward, the flipping claws 656 gradually come into contact with and abut against the side wall of the bump 653, and then rotate clockwise. The flipping claws 656 drive the limiting sleeve 654 and the rotating shaft 652 to rotate, so that the rotating shaft 652 is released from the restriction of the clamping assembly 68, and the cleaning brush 66 flips to the left side of the rotating shaft 652 and abuts against the top wall of the dust collection plate 62. The cleaning brush 66 moves rightward to sweep the metal debris and sewage mixture on the dust collection plate 62 into the dust collection box 64, and the flipping claws 656 flip at the limiting groove 657 without blocking the movement of the first sliding sleeve 651 and the cleaning brush 66; slide the first sliding sleeve 651 leftward again, the flipping claws 656 rotate counterclockwise, driving the cleaning brush 66 to flip to the right side of the rotating shaft 652, and the clamping assembly 68 clamps again to make the position between the rotating shaft 652 and the first sliding sleeve 651 relatively fixed, and the cleaning brush 66 is suspended and stable; thus, during the continuous operation of the equipment, the dust collection assembly 60 forms an automatic cleaning cycle; when the cutting mechanism 50 reciprocates, the linkage assembly 67 drives the first sliding sleeve 651 to slide left and right, moving rightward for cleaning and moving leftward for resetting and fixing; the dust collection plate 62 is elastically connected to the frame 10 through the third elastic telescopic rod 61 and is inclined downward, which is conducive to the rapid sliding of the sewage mixture into the dust collection box 64.

[0057] The linkage assembly 67 includes a connecting rod 671, a second sliding sleeve 672, and an extension rod 673; when the driving frame 41 is driven by the fourth motor 47 and moves through the threaded transmission of the second screw rod 45 and the second nut 46, the extension rod 673 fixed to the side wall of the driving frame 41 moves accordingly; at this time, the second sliding sleeve 672 slidably connected to the extension rod 673 slides on its side wall due to the displacement of the extension rod 673, and the second sliding sleeve 672 drives the first sliding sleeve 651 to slide on the side plate 63 through the connecting rod 671; the linkage assembly 67 enables linkage with the movement of the cutting mechanism 50, so that during the movement of the cutting mechanism 50, the flipping assembly 65 can cooperate with the cutting mechanism 50 to clean the dust collection plate 62, improving the cleaning effect of the dust collection assembly 60.

[0058] The clamping component 68 includes a first clamping strip 681 and a second clamping strip 682; when the first sliding sleeve 651 slides leftward along the side plate 63, the second clamping strip 682 on its inner wall is clamped with the first clamping strip 681 on the rotating shaft 652, and the cleaning brush 66 is suspended to prevent the dust on the dust collecting plate 62 from moving away from the dust collecting box 64; when the first sliding sleeve 651 slides rightward, the convex block 653 presses against the flipping claw 656, and drives the limiting sleeve 654 and the rotating shaft 652 to rotate clockwise through the limiting groove 657. The first clamping strip 681 undergoes elastic deformation and disengages from the second clamping strip 682, so that the rotating shaft 652 is disengaged from the limit of the clamping component 68, and the cleaning brush 66 rotates clockwise to the left side of the rotating shaft 652 and abuts against the top wall of the dust collecting plate 62, and slides rightward to sweep the sewage mixture into the dust collecting box 64; when the first sliding sleeve 651 slides leftward again, the convex block 653 presses against the flipping claw 656, making it abut against the bottom wall of the limiting groove 657, driving the limiting sleeve 654, the rotating shaft 652 and the cleaning brush 66 to rotate counterclockwise, and the cleaning brush 66 returns to the right side of the rotating shaft 652; when the rotating shaft 652 rotates, the first clamping strip 681 abuts against the second clamping strip 682, undergoes elastic deformation, and forms a clamping again, and the cleaning brush 66 is suspended and stable, avoiding the dust on the dust collecting plate 62 from moving away from the dust collecting box 64.
