Description

Technical Field

[0001] The present invention relates to the technical field of water-guided laser cutting, and specifically, to a water-guided laser cutting machine for transformer tank shells. Background Art

[0002] A water-guided laser cutting machine is a high-end processing equipment integrating water-guided cooling technology and laser cutting technology. By using water as a cooling medium, it optimizes the thermal management in the laser process, effectively reduces the thermal impact generated during processing, reduces material deformation, and keeps the cutting edge smooth.

[0003] A patent with the patent publication number CN221454654U discloses a water-guided laser cutting machine, which includes a water-guided laser cutting machine body, a console, and a door body. A placement box is fixedly connected to the left side of the water-guided laser cutting machine body. A water storage box is arranged at the bottom of the placement box, and a blowing mechanism is arranged on the top of the placement box. The blowing mechanism includes a connecting block, two blowers, and an exhaust plate. The front side of the connecting block is fixedly connected to the rear side of the exhaust plate. The bottom of the blower is fixedly communicated with the top of the exhaust plate. A fixed block is fixedly connected to the rear side of the placement box, and an electric telescopic rod is fixedly connected to the top of the fixed block, which solves the problem that after most existing water-guided laser cutting machines finish cutting a plate, water stains will adhere to the surface of the plate, making it inconvenient to clean the water stains on the surface of the plate and inconvenient to directly carry out the next processing and storage of the cut plate.

[0004] However, this device still has deficiencies: Although this device can clean the water stains on the material surface, it is difficult to ensure good stability during the cutting process of the material, which easily increases the probability of the material shifting during the cutting process. When the material shifts, it is easy to interfere with the cutting path, easily cause the cutting size of the material not to meet the initial setting, and easily result in material waste. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a water-guided laser cutting machine for transformer tank shells, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A water-guided laser cutting machine for transformer tank shells includes a device main body. A collection groove is opened at the bottom of the inner wall of the device main body. A moving component is arranged at the bottom of the device main body. A control module is arranged on the right side of the device main body. A workbench is arranged at the bottom of the inner wall of the device main body. A slide rail is arranged at the top of the inner wall of the device main body. An electric telescopic rod is arranged inside the slide rail. A cutting component is arranged at the bottom of the telescopic end of the electric telescopic rod.

[0007] An anti-offset device is provided inside the device main body. An anti-scratch device is provided inside the anti-offset device. An anti-residue device is provided inside the anti-scratch device;

[0008] The anti-offset device includes an electric rotating rod. The bottom of the electric rotating rod is rotatably installed at the bottom edge of the inner wall of the device main body. The outer wall of the electric rotating rod penetrates and is threadedly connected to a U-shaped frame. The outer wall of the U-shaped frame is slidably installed on the inner wall of the device main body. Two U-shaped push plates are symmetrically and hingedly installed inside the U-shaped frame. Torsion springs are provided between the tops of the two U-shaped push plates and the inside of the U-shaped frame. A cross bar is fixedly installed on the side of the U-shaped push plate away from the axis of the device main body. The outer wall of the cross bar penetrates and is rotatably installed with a sliding plate. An L-shaped clamping plate is fixedly installed on the side of the sliding plate close to the center of the workbench. A soft rubber arc block is fixedly installed inside the U-shaped groove of the L-shaped clamping plate. The top of the sliding plate is hinged with an inclined plate through a torsion spring. An air dryer is hinged on the top of the inclined plate.

[0009] According to the above technical solution, the side of the sliding plate close to the axis of the device main body is slidably installed on the outer wall of the workbench. A U-shaped groove is provided on the side of the L-shaped clamping plate close to the axis of the device main body. The outer arc surface of the soft rubber arc block protrudes from the side of the L-shaped clamping plate close to the axis of the workbench. The side of the air dryer away from the cutting assembly is slidably installed on the inner wall of the U-shaped frame through a spring. Place the raw material to be cut on the top of the workbench. Drive the slide rail through the control module to drive the electric telescopic rod to move horizontally inside itself. The telescopic end of the electric telescopic rod drives the cutting assembly to move synchronously. The cutting assembly cuts the raw material through a laser water line; before the telescopic end of the electric telescopic rod drives the cutting assembly to move downward for cutting work, start the electric rotating rod. The electric rotating rod can rotate counterclockwise and clockwise along the bottom of the inner wall of the device main body. When the electric rotating rod rotates counterclockwise, it drives the U-shaped frame to slide downward along the inner wall of the device main body through a spiral groove. Conversely, the U-shaped frame slides upward. When the U-shaped frame drives the U-shaped push plate to move downward, the U-shaped push plate drives the cross bar to move synchronously. The cross bar is limited by the sliding plate and thus rotates inside the sliding plate. Through the transmission of force, the hinge shaft between the U-shaped push plate and the U-shaped frame starts to rotate. The U-shaped push plate gradually moves in an arc trajectory during the descent. At this time, the cross bar pushes the sliding plate to slide horizontally along the outer wall of the workbench. The sliding plate drives the L-shaped clamping plate to move synchronously. The L-shaped clamping plate drives the soft rubber arc block to move synchronously. During the horizontal movement of the soft rubber arc block, it will contact the outer wall of the edge of the raw material and generate a resistance force. The soft rubber arc block deforms gradually towards the inside of the L-shaped clamping plate through the resistance force until the soft rubber arc block deforms to fit the outer wall of the L-shaped clamping plate; when the sliding plate moves towards the center of the device main body, it drives the inclined plate to move synchronously. The inclined plate is limited by the air dryer and causes its hinge shaft to start to rotate. At this time, the inclined plate moves in an arc trajectory with the hinge shaft as the axis, thereby driving the air dryer to slide upward along the inner wall of the U-shaped frame.

[0010] According to the above technical solution, the anti-scratch device includes a plurality of rotating wheels, a transmission rod, a plurality of telescopic plates and a water-absorbing cotton roller. The plurality of rotating wheels are symmetrically and rotatably installed inside the U-shaped push plate. Both ends of the transmission rod are fixedly installed at the center of one side of the rotating wheel close to the axis of the U-shaped push plate. The plurality of telescopic plates are fixedly installed on the outer wall of the transmission rod. Both ends of the water-absorbing cotton roller are rotatably installed inside the sliding grooves at the telescopic ends of the telescopic plates.

[0011] According to the above technical solution, the plurality of telescopic plates are evenly distributed on the outer wall of the transmission rod. A sliding groove is opened at one end of the telescopic end of the telescopic plate away from the transmission rod. When the U-shaped push plate moves downward in an arc-shaped trajectory, it drives the rotating wheels to move synchronously. At this time, the outer wall of the rotating wheel contacts the top edge of the raw material and gradually moves toward the center of the workbench. The rotating wheel starts to rotate along the inside of the U-shaped push plate by the friction force between it and the top of the raw material. The rotating wheel drives the transmission rod to rotate, and the transmission rod drives the telescopic plates to revolve. The telescopic end of the telescopic plate drives the water-absorbing cotton roller to revolve and continuously contacts the surface of the top of the raw material to generate friction force. The water-absorbing cotton roller rotates inside the telescopic end of the telescopic plate by the friction force. When the U-shaped push plate drives the rotating wheels to reset after cutting, the water-absorbing cotton roller rotates in reverse and resets synchronously.

[0012] According to the above technical solution, the anti-scratch device further includes a U-shaped plate, a transmission belt, a reciprocating screw rod, a plurality of sleeves and an arc-shaped scraper. The top of the U-shaped plate is fixedly installed on the top inner wall of the U-shaped push plate. The inner wall of the bottom end of the transmission belt is sleeved and drivingly installed on the outer wall of the transmission rod. The outer wall of the reciprocating screw rod passes through and is rotatably installed inside the U-shaped plate. The plurality of sleeves are internally passed through and rotatably installed at the outer wall edges of both ends of the reciprocating screw rod. The top of the arc-shaped scraper is fixedly installed on the outer wall of the sleeve.

[0013] According to the above technical solution, both ends of the reciprocating screw rod pass through the inside of the U-shaped plate. The outer wall of one end of the reciprocating screw rod close to the back of the device body is sleeved on the inner wall of the top end of the transmission belt. The bottom of the arc-shaped scraper contacts the outer wall of the rotating wheel. The U-shaped push plate drives the U-shaped plate to move synchronously, and the U-shaped plate drives the reciprocating screw rod to move synchronously. At the same time, the transmission rod drives the reciprocating screw rod to rotate inside the U-shaped plate through the transmission belt. Since the sleeve is rotatably connected to the reciprocating screw rod, the sleeve is kept stationary, and the sleeve makes the arc-shaped scraper stationary synchronously, and the arc-shaped scraper contacts the outer wall of the rotating wheel during rotation.

[0014] According to the above technical solution, the anti-residue device includes a plurality of magnetic plates, a fixed block, a limiting rod and a linkage plate. The plurality of magnetic plates are internally passed through and movably installed on the outer wall of the reciprocating screw rod. The fixed block is fixedly installed on the outer wall of the U-shaped plate on the side close to the U-shaped push plate. The limiting rod is fixedly installed on the side of the fixed block close to the center of the U-shaped plate. The bottom of the linkage plate is fixedly installed on the top of the magnetic plate.

[0015] According to the above technical solution, the bottom arc surface of the magnetic plate is located on the movement trajectory of the absorbent cotton roller, the outer wall of the limit rod is slidably connected to the side of the magnetic plate close to the U-shaped plate, and the reciprocating spiral groove on its own outer wall limits the built-in block of the magnetic plate when the reciprocating screw rotates, driving the magnetic plate to slide back and forth horizontally along the outer wall of the limit rod and reset, and the limit rod is kept stable by the limitation of the fixed block, and at the same time, the magnetic plate continuously scrapes the outer wall of the absorbent cotton roller during the horizontal movement, and the outer wall of the absorbent cotton roller contacts the bottom arc surface of the magnetic plate to generate resistance force, and the transmission of force causes the telescopic end of the telescopic plate to be synchronously forced to shrink toward the inside of its own fixed end. During the contraction process, friction is generated between the absorbent cotton roller and the magnetic plate and drives the absorbent cotton roller to rotate, and at the same time, the linkage plate relies on the limitation of several magnetic plates to cause several magnetic plates to move synchronously.

[0016] According to the above technical solution, the anti-residue device also includes a resistance plate, a telescopic shield, an L-shaped hollow plate and several vibration plates. The bottom outer wall of the resistance plate is fixedly installed inside the linkage plate, the front of the fixed end of the telescopic shield is fixedly installed on the back of the resistance plate, the L-shaped hollow plate is fixedly installed on the edge of the outer wall of the U-shaped plate close to the U-shaped push plate, and several vibration plates are equidistant from the side of the U-shaped push plate and fixedly installed on the side of the L-shaped hollow plate close to the U-shaped push plate.

[0017] The U-shaped plate is fixed to the rear of the U-shaped plate so that the sliding surface of the U-shaped plate can be adjusted according to the situation of the U-shaped plate being in the forward direction.

[0018] The present invention provides a transformer casing water-conducting laser cutting machine. It has the following beneficial effects:

[0019] (1) The present invention sets an anti-deviating device, and cooperates with an electric rotating rod, a circular frame, a U-shaped push plate, a cross bar, a sliding plate, an L-shaped splint, a soft rubber arc block, an inclined plate and an air dryer. The soft rubber arc block is continuously deformed during movement to increase the friction between the L-shaped splint and the raw material, effectively improving the resistance strength of the L-shaped splint to the raw material. The sliding plate guides the raw material in the horizontal direction to ensure that the raw material is always parallel to the workbench during the cutting process, ensuring that the raw material has good stability during the cutting process, avoiding the deviation of the raw material due to poor stability during the cutting process, and preventing interference with the cutting path so that the cutting diameter of the raw material does not meet the initial setting; at the same time, the air dryer can be closer to the workbench for air drying during the cutting preparation and after the cutting is completed, ensuring a relatively dry working environment inside the device body, and away from the workbench during cutting to avoid interference with the laser waterline of the cutting component and thus reducing the cutting quality.

[0020] (2) The present invention sets an anti-scratch device, and cooperates with the U-shaped push plate, the rotating wheel, the transmission rod, the telescopic plate, the absorbent cotton roller, the U-shaped plate, the transmission belt, the reciprocating screw, the sleeve and the arc scraper to promote the rotating wheel and the telescopic plate to exert downward pressure on the top of the raw material, thereby improving the overall stability of the raw material during the movement of the L-shaped splint, preventing the raw material from being offset during the cutting preparation work, and improving the cutting accuracy. The absorbent cotton roller rotates continuously to clean the granular impurities on the surface of the raw material, thereby avoiding the granular matter interfering with the cutting laser and causing a rough incision, and the absorbent cotton roller rotates and evenly absorbs the water droplets around the incision when it is reset, thereby avoiding the cutting debris and water droplets interfering with the subsequent cutting work of the raw material; and the arc scraper contacts and scrapes the outer wall of the rotating wheel, effectively removing the granular impurities attached to the outer wall of the rotating wheel when it moves on the top of the raw material, thereby avoiding the impurities attached to the outer wall of the rotating wheel during the rotation of the rotating wheel continuously scratching the top surface of the raw material, resulting in scratches on the top of the raw material and reducing the quality of the finished product.

[0021] (3) The present invention sets up an anti-residue device, and cooperates with a reciprocating screw, a magnetic plate, a fixed block, a limit rod, a linkage plate, a resistance plate, a telescopic shield, an L-shaped hollow plate and a vibration plate. The magnetic plate scrapes and absorbs the magnetic debris attached to the outer wall of the absorbent cotton roller after the raw material is cut. At the same time, when the absorbent cotton roller rotates, the magnetic plate effectively expands the scraping range of the absorbent cotton roller to prevent debris from remaining, thereby ensuring the overall cleanliness of the absorbent cotton roller and preventing the magnetic debris carried on the surface of the absorbent cotton roller during revolution and rotation from damaging the raw material; and relies on the telescopic shield to block a small amount of water droplets splashed during the cutting process, preventing the water droplets from carrying debris and splashing everywhere, thereby increasing the amount of debris residue inside the device body, avoiding increasing the difficulty of maintaining the various components inside the device body, and relying on the vibration force to lift the magnetic plate to reduce the adhesion strength of the magnetic debris on the outer wall of the absorbent cotton roller, thereby improving the removal effect of the magnetic debris.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] An anti-drift device 4 is provided inside the device body 1, an anti-scratch device 5 is provided inside the anti-drift device 4, and an anti-residue device 6 is provided inside the anti-scratch device 5;

[0035] The anti-deviation device 4 includes an electric rotating rod 41, the bottom of the electric rotating rod 41 is rotatably installed at the bottom edge of the inner wall of the device body 1, the outer wall of the electric rotating rod 41 passes through and is threadedly connected with a circular frame 42, the outer wall of the circular frame 42 is slidably installed on the inner wall of the device body 1, the interior of the circular frame 42 is symmetrical and hinged with two U-shaped push plates 43, and a torsion spring is provided between the top of the two U-shaped push plates 43 and the inside of the circular frame 42, the U-shaped push plate 43 is fixedly installed with a cross bar 44 on the side away from the axis of the device body 1, the outer wall of the cross bar 44 passes through and rotatably installed with a sliding plate 45, the sliding plate 45 is fixedly installed with an L-shaped splint 46 on the side close to the center of the workbench 22, and a soft rubber arc block 47 is fixedly installed inside the U-shaped groove of the L-shaped splint 46, the top of the sliding plate 45 is hinged with an inclined plate 48 through a torsion spring, and the top of the inclined plate 48 is hinged with an air dryer 49.

[0036] According to the above technical solution, the sliding plate 45 is slidably installed on the outer wall of the workbench 22 near the axis of the device body 1, and a U-shaped groove is provided on the side of the L-shaped splint 46 near the axis of the device body 1. The arc surface of the outer wall of the soft rubber arc block 47 is convex on the side of the L-shaped splint 46 near the axis of the workbench 22, and the air dryer 49 is slidably installed on the inner wall of the circular frame 42 away from the cutting component 32 through a spring. Through the above cooperation, the soft rubber arc block 47 is continuously deformed during the movement to increase the friction between the L-shaped splint 46 and the raw material, effectively improving the resistance strength of the L-shaped splint 46 to the raw material, and the raw material is horizontally dispersed through the sliding plate 45 Guide, ensure that the raw material is always in a parallel position with the workbench 22 during the cutting process, ensure that the raw material has good stability during the cutting process, avoid the raw material from shifting due to poor stability during the cutting process, and prevent interference with the cutting path, thereby causing the cutting diameter of the raw material to not meet the initial setting; through the above cooperation, the air dryer 49 can be closer to the workbench 22 for air drying during cutting preparation and after cutting is completed, ensuring a relatively dry working environment inside the device body 1, and staying away from the workbench 22 when cutting is in progress, avoiding interference with the laser waterline of the cutting component 32 and thereby reducing the cutting quality.

[0037] When in use, the material to be cut is placed on the top of the workbench 22, and the control module 21 drives the slide rail 3 to drive the electric telescopic rod 31 to move horizontally inside itself. The telescopic end of the electric telescopic rod 31 drives the cutting assembly 32 to move synchronously, and the cutting assembly 32 cuts the material through the laser waterline; before the telescopic end of the electric telescopic rod 31 drives the cutting assembly 32 to move downward for cutting, the electric rotating rod 41 is started, and the electric rotating rod 41 can realize counterclockwise and clockwise rotation along the bottom of the inner wall of the device body 1. When the electric rotating rod 41 rotates counterclockwise, it drives the circular frame 42 to slide downward along the inner wall of the device body 1 through the spiral groove, and vice versa. When the U-shaped push plate 43 is moved downwards by the circular frame 42, the U-shaped push plate 43 drives the cross bar 44 to move synchronously. The cross bar 44 is limited by the sliding plate 45 and rotates inside the sliding plate 45. The hinge shaft between the U-shaped push plate 43 and the circular frame 42 starts to rotate through the force transmission. The U-shaped push plate 43 gradually moves in an arc trajectory during the descending process. At this time, the cross bar 44 pushes the sliding plate 45 to slide horizontally along the outer wall of the workbench 22. The sliding plate 45 drives the L-shaped splint 46 to move synchronously. The L-shaped splint 46 drives the soft rubber arc block 47 to move synchronously. During the horizontal movement of the soft rubber arc block 47, it will contact the outer wall of the edge of the raw material and generate resistance. The arc block 47 is gradually deformed toward the inner direction of the L-shaped splint 46 by the resistance force, until the soft rubber arc block 47 is deformed to fit the outer wall of the L-shaped splint 46. Through the above cooperation, the soft rubber arc block 47 is continuously deformed during the movement to increase the friction between the L-shaped splint 46 and the raw material, effectively improving the resistance strength of the L-shaped splint 46 to the raw material. The raw material is guided horizontally by the sliding plate 45 to ensure that the raw material is always in a parallel position with the workbench 22 during the cutting process, ensuring that the raw material has good stability during the cutting process, avoiding the raw material from deviating due to poor stability during the cutting process, and preventing interference with the cutting path, thereby causing the cutting diameter of the raw material to be affected. It does not conform to the initial setting; when the sliding plate 45 moves toward the center of the device body 1, it drives the inclined plate 48 to move synchronously. The inclined plate 48 is limited by the air dryer 49, causing its own hinge shaft to start to rotate. At this time, the inclined plate 48 moves in an arc trajectory with the hinge shaft as the axis, thereby pushing the air dryer 49 to slide upward along the inner wall of the circular frame 42. Through the above cooperation, the air dryer 49 can be closer to the workbench 22 for air drying during cutting preparation and after cutting is completed, ensuring a relatively dry working environment inside the device body 1, and staying away from the workbench 22 during cutting to avoid interference with the laser waterline of the cutting component 32 and thereby reducing the cutting quality.

[0038] See also Figures 1-9 , based on the above embodiment, another embodiment of the present invention further includes an anti-scratch device 5;

[0039] According to the above technical solution, the anti-scratch device 5 includes a plurality of rotating wheels 51, a transmission rod 52, a plurality of telescopic plates 53, and a water-absorbing cotton roller 54. A plurality of rotating wheels 51 are symmetrically and rotatably installed inside the U-shaped push plate 43. Both ends of the transmission rod 52 are fixedly installed at the center of one side of the rotating wheel 51 close to the axis of the U-shaped push plate 43. A plurality of telescopic plates 53 are fixedly installed on the outer wall of the transmission rod 52. Both ends of the water-absorbing cotton roller 54 are rotatably installed inside the chute at the telescopic end of the telescopic plate 53.

[0040] According to the above technical solution, a plurality of telescopic plates 53 are evenly distributed on the outer wall of the transmission rod 52. A chute is provided at one end of the telescopic end of the telescopic plate 53 away from the transmission rod 52. Through the above cooperation, the rotating wheel 51 and the telescopic plate 53 apply a downward pressure on the top of the raw material, improving the overall stability of the raw material during the movement of the L-shaped clamping plate 46, preventing the raw material from shifting during the cutting preparation work, improving the cutting accuracy. The water-absorbing cotton roller 54 rotates to continuously clean the particulate impurities on the surface of the raw material, avoiding the interference of the particulate matter with the cutting laser and resulting in a rough cut surface. When the water-absorbing cotton roller 54 returns to its original position, it rotates and evenly absorbs the water droplets around the cut, avoiding the interference of the cutting debris and water droplets with the subsequent cutting work of the raw material.

[0041] According to the above technical solution, the anti-scratch device 5 further includes a U-shaped plate 55, a transmission belt 56, a reciprocating lead screw 57, a plurality of collars 58, and a curved surface scraping plate 59. The top of the U-shaped plate 55 is fixedly installed on the top inner wall of the U-shaped push plate 43. The bottom inner wall of the transmission belt 56 is sleeved and drivingly installed on the outer wall of the transmission rod 52. The outer wall of the reciprocating lead screw 57 passes through and is rotatably installed inside the U-shaped plate 55. The inside of a plurality of collars 58 passes through and is rotatably installed at the outer wall edges of both ends of the reciprocating lead screw 57. The top of the curved surface scraping plate 59 is fixedly installed on the outer wall of the collar 58.

[0042] According to the above technical solution, both ends of the reciprocating lead screw 57 pass through the inside of the U-shaped plate 55. The outer wall of one end of the reciprocating lead screw 57 close to the back of the device main body 1 is sleeved on the top inner wall of the transmission belt 56. The bottom of the curved surface scraping plate 59 contacts the outer wall of the rotating wheel 51. Through the above cooperation, the curved surface scraping plate 59 contacts and scrapes the outer wall of the rotating wheel 51, effectively removing the particulate impurities attached to the outer wall of the rotating wheel 51 during the movement on the top of the raw material, avoiding the continuous scratching of the surface of the top of the raw material by the impurities attached to the outer wall of the rotating wheel 51 during the rotation of the rotating wheel 51, resulting in scratches on the top of the raw material and reducing the finished product quality.

[0043] During use, when the U-shaped push plate 43 moves downward along an arc-shaped trajectory, it drives the synchronous movement of the rotating wheel 51. At this time, the outer wall of the rotating wheel 51 contacts the top edge of the raw material and gradually moves towards the center of the workbench 22. The rotating wheel 51 starts to rotate within the U-shaped push plate 43 by the frictional force between it and the top of the raw material. The rotating wheel 51 drives the transmission rod 52 to rotate, and the transmission rod 52 drives the telescopic plate 53 to revolve. The telescopic end of the telescopic plate 53 drives the water-absorbing cotton roller 54 to revolve and continuously contacts the surface of the top of the raw material to generate frictional force. The water-absorbing cotton roller 54 rotates within the telescopic end of the telescopic plate 53 by the frictional force. When the U-shaped push plate 43 drives the rotating wheel 51 to reset after cutting, the water-absorbing cotton roller 54 rotates in the reverse direction and resets synchronously. Through the above cooperation, the rotating wheel 51 and the telescopic plate 53 apply a downward pressure on the top of the raw material, improving the overall stability of the raw material during the movement of the L-shaped clamping plate 46, preventing the raw material from shifting during the cutting preparation work, improving the cutting accuracy, continuously cleaning the particulate impurities on the surface of the raw material by the rotation of the water-absorbing cotton roller 54, avoiding the interference of the particulate matter with the cutting laser and resulting in rough cut surfaces, and evenly absorbing the water droplets around the cut by the rotation of the water-absorbing cotton roller 54 during its reset, avoiding the interference of the cutting debris and water droplets with the subsequent cutting work of the raw material; the U-shaped push plate 43 drives the U-shaped plate 55 to move synchronously, the U-shaped plate 55 drives the reciprocating lead screw 57 to move synchronously, and at the same time, the transmission rod 52 drives the reciprocating lead screw 57 to rotate within the U-shaped plate 55 through the transmission belt 56. Since the collar 58 is rotatably connected to the reciprocating lead screw 57, the collar 58 is kept stationary, the collar 58 causes the arc-shaped scraping plate 59 to be synchronously stationary, and the arc-shaped scraping plate 59 contacts the outer wall of the rotating wheel 51 during rotation. Through the above cooperation, the arc-shaped scraping plate 59 contacts and scrapes the outer wall of the rotating wheel 51, effectively removing the particulate impurities attached to the outer wall of the rotating wheel 51 during its movement on the top of the raw material, avoiding the continuous scratching of the surface of the top of the raw material by the impurities attached to its own outer wall during the rotation of the rotating wheel 51, resulting in scratches on the top of the raw material and reducing the product quality.

[0044] Please refer to Figures 1-9 , on the basis of the above embodiments, in another embodiment of the present invention, a residue prevention device 6 is further included;

[0045] According to the above technical solution, the residue prevention device 6 includes a plurality of magnetic plates 61, a fixed block 62, a limiting rod 63, and a linkage plate 64. A plurality of magnetic plates 61 are all penetrated and movably installed on the outer wall of the reciprocating lead screw 57. The side of the fixed block 62 close to the U-shaped push plate 43 is fixedly installed on the outer wall of the U-shaped plate 55. The limiting rod 63 is fixedly installed on the side of the fixed block 62 close to the center of the U-shaped plate 55. The bottom of the linkage plate 64 is fixedly installed on the top of the magnetic plate 61.

[0046] According to the above technical solution, the arc surface at the bottom of the magnetic plate 61 is located on the movement trajectory of the absorbent cotton roller 54, and the outer wall of the limiting rod 63 is slidably connected to the side of the magnetic plate 61 close to the U-shaped plate 55. Through the above cooperation, the magnetic plate 61 scrapes and absorbs the magnetic debris after the raw material is cut and attached to the outer wall of the absorbent cotton roller 54. At the same time, when the absorbent cotton roller 54 rotates, the scraping range of the magnetic plate 61 on the absorbent cotton roller 54 is effectively expanded to prevent debris from remaining, thereby ensuring the overall cleanliness of the absorbent cotton roller 54 and preventing the magnetic debris carried on the surface of the absorbent cotton roller 54 during revolution and rotation from damaging the raw material.

[0047] According to the above technical solution, the anti-residue device 6 also includes a resistance plate 65, a telescopic shield plate 66, an L-shaped hollow plate 67 and a number of vibration plates 68. The bottom outer wall of the resistance plate 65 is fixedly installed inside the linkage plate 64, the front of the fixed end of the telescopic shield plate 66 is fixedly installed on the back of the resistance plate 65, the L-shaped hollow plate 67 is fixedly installed on the edge of the outer wall of the U-shaped plate 55 close to the U-shaped push plate 43, and a number of vibration plates 68 are equidistant from the side of the U-shaped push plate 43 and fixedly installed on the side of the L-shaped hollow plate 67 close to the U-shaped push plate 43.

[0048] According to the above technical solution, the top of the resistance plate 65 is slidably installed on the top of the inner wall of the U-shaped plate 55, and the back of the telescopic end of the telescopic shield 66 is fixedly installed on the back of the inner wall of the U-shaped plate 55. Several vibration plates 68 are located on the arc motion trajectory of the resistance plate 65. Through the above cooperation, the telescopic shield 66 is used to block the small amount of water droplets splashed during the cutting process, preventing the water droplets from carrying debris and splashing everywhere, thereby increasing the amount of debris remaining inside the device body 1, avoiding increased difficulty in maintaining various components inside the device body 1, and at the same time relying on the vibration force to lift the magnetic plate 61 to reduce the adhesion strength of the magnetic debris on the outer wall of the absorbent cotton roller 54, thereby improving the removal effect of the magnetic debris.

[0049] When in use, the reciprocating screw 57 limits the built-in block of the magnetic plate 61 through the reciprocating spiral groove on its outer wall when rotating, driving the magnetic plate 61 to slide back and forth horizontally along the outer wall of the limit rod 63 and reset, and the limit rod 63 is kept stable by the limit of the fixed block 62. At the same time, the magnetic plate 61 continuously scrapes the outer wall of the absorbent cotton roller 54 during the horizontal movement, and the outer wall of the absorbent cotton roller 54 contacts the arc surface at the bottom of the magnetic plate 61 to generate a resistance force, and the transmission of force causes the telescopic end of the telescopic plate 53 to be synchronously forced to retract toward the inside of its own fixed end. During the retraction process, there will be a The friction force is generated and the absorbent cotton roller 54 is driven to rotate. At the same time, the linkage plate 64 limits the plurality of magnetic plates 61 to cause the plurality of magnetic plates 61 to move synchronously. Through the above cooperation, the magnetic plates 61 are used to scrape and absorb the magnetic debris of the raw material cut from the outer wall of the absorbent cotton roller 54. At the same time, when the absorbent cotton roller 54 rotates, the scraping range of the magnetic plate 61 on the absorbent cotton roller 54 is effectively expanded to prevent debris from remaining, thereby ensuring the overall cleanliness of the absorbent cotton roller 54 and preventing the magnetic debris carried on the surface of the absorbent cotton roller 54 during revolution and rotation from causing damage to the raw material; the linkage plate 64 moves horizontally and repeatedly The contact plate 65 is driven to move synchronously during the positioning process, and the contact plate 65 drives the telescopic shield 66 to move synchronously. When the telescopic shield 66 moves horizontally, its own telescopic end will be limited by the U-shaped plate 55. At this time, the fixed end of the telescopic shield 66 continuously covers its own telescopic end. At the same time, the top arc surface of the contact plate 65 continuously contacts the vibration plate 68 during the horizontal movement. The vibration plate 68 is limited and kept stationary by the L-shaped hollow plate 67. At this time, the vibration plate 68 bends and deforms under the resistance of the contact plate 65. As the contact plate 65 continues to move horizontally and the arc surface between the two guides, the contact plate 65 is pushed back. 5 will pass over the vibration plate 68, and the vibration plate 68 will swing back and forth during the process of restoring itself through its own toughness, thereby generating vibration, and the magnetic plate 61 will be caused to generate slight vibration synchronously through the transmission of force. Through the above cooperation, the telescopic shielding plate 66 is used to block the small amount of water droplets splashed during the cutting process, so as to prevent the water droplets from carrying debris and splashing around, thereby increasing the amount of debris remaining inside the device body 1, avoiding increased difficulty in maintaining various components inside the device body 1, and at the same time relying on the vibration force to lift the magnetic plate 61 to reduce the adhesion strength of the magnetic debris on the outer wall of the absorbent cotton roller 54, thereby improving the removal effect of the magnetic debris.
