Description

Technical Field

[0001] The present application relates to the technical field of laser cutting equipment, and in particular to a laser cutting machine. Background Art

[0002] A laser cutting machine uses a laser beam emitted from a laser generator, focused through an optical system into a high-power, high-density laser beam. The laser beam strikes the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the beam and workpiece move relative to each other, a slit is formed in the material, achieving the desired cutting effect.

[0003] In related technology, a laser cutting machine includes a frame and several support bars mounted on the frame. The support bars are spaced apart along the length of the frame, with gaps formed between adjacent support bars. A laser cutting gun is also slidably mounted on the frame, positioned above the support bars. During use, a workpiece is placed on the support bars, and the laser cutting gun slides along a predetermined path, cutting the workpiece. Waste material removed by the laser cutting gun falls through the gaps into the frame.

[0004] However, during the operation of the laser cutting machine in the related art, the waste cut by the laser cutting gun is easy to adhere to the support bar after hot melting. Over time, the gap formed between two adjacent support bars is easy to gradually decrease, and the waste cut by the laser cutting gun is difficult to fall into the frame through the gap, resulting in the waste cut by the laser cutting gun easily accumulating on the support bar, which is inconvenient for subsequent cutting of the workpiece. Summary of the Invention

[0005] In order to improve the problem in the related art that during the operation of the laser cutting machine, the waste cut by the laser cutting gun is easily adhered to the support bar after hot melting. Over time, the gap formed between two adjacent support bars is likely to gradually decrease, and the waste cut by the laser cutting gun is difficult to fall into the frame through the gap, which causes the waste cut by the laser cutting gun to easily accumulate on the support bar, making it inconvenient to cut the subsequent workpiece. The present application provides a laser cutting machine.

[0006] The laser cutting machine provided in this application adopts the following technical solution:

[0007] A laser cutting machine comprises a frame and a plurality of support bars arranged on the frame, wherein the plurality of support bars are spaced apart along the length direction of the frame, and gaps are formed between two adjacent support bars. A laser cutting gun is slidably provided on the frame, and the laser cutting gun is located above the support bars. A mounting seat is slidably provided on the frame, and a plurality of mounting plates are provided on the mounting seat. The plurality of mounting plates correspond to the plurality of gaps one-to-one, and the mounting plates are located in the corresponding gaps.

[0008] The two opposing side walls of the mounting plate are each provided with a cleaning plate for scraping the support strips, and the cleaning plate abuts against the adjacent support strips. The frame is provided with a sliding mechanism for driving the mounting seat to slide along the length direction of the support strip so that the cleaning plate scrapes the support strips.

[0009] By adopting the above technical solution, the laser cutting machine of the present application drives the mounting seat to slide along the length direction of the support bar each time after the cutting operation is completed. Since the cleaning plate is arranged on the mounting plate, and the mounting plate is arranged on the mounting seat, when the mounting seat slides along the length direction of the support bar, the mounting seat can drive the cleaning plate to slide along the length direction of the support bar.

[0010] Furthermore, because the cleaning plate abuts against the adjacent support strips, when the cleaning plate slides along the length direction of the support strips, the cleaning plate can scrape the adjacent support strips, thereby achieving the purpose of cleaning the support strips.

[0011] It can be seen from this that during the operation of the laser cutting machine in this application, although the waste cut by the laser cutting gun is easily adhered to the support bar after being hot-melted, due to the cleaning plate scraping the support bar, the gap formed between two adjacent support bars is not easy to gradually reduce over time, and the waste cut by the laser cutting gun is more likely to fall through the gap and onto the supporting plate, thereby making it difficult for the waste cut by the laser cutting gun to accumulate on the support bar, facilitating the subsequent cutting of workpieces.

[0012] Preferably, the sliding mechanism includes a reciprocating screw rotatably arranged on the frame and a sliding drive motor arranged on the frame and used to drive the reciprocating screw to rotate, the reciprocating screw is arranged along the length direction of the support bar, and the mounting seat is threadedly engaged with the reciprocating screw;

[0013] The sliding mechanism further includes a guide component which is arranged between the frame and the mounting seat and is used to guide the mounting seat to slide along the length direction of the support bar.

[0014] By adopting the above technical solution, the mounting seat is threadedly connected to the reciprocating screw. Since the mounting seat is guided by the guide assembly, when the drive motor drives the reciprocating screw to rotate, the reciprocating screw can drive the mounting seat to slide along the length direction of the support bar.

[0015] Preferably, the guide assembly includes a guide rail provided on the frame and a guide sleeve provided on the mounting seat, the guide rail is provided along the length direction of the support bar, and the guide sleeve is slidably engaged with the guide rail.

[0016] By adopting the above technical solution and utilizing the sliding cooperation between the guide rail and the guide sleeve, when the reciprocating screw rotates, the mounting seat does not rotate together with the reciprocating screw, but slides along the length direction of the reciprocating screw.

[0017] Preferably, a sliding groove for sliding the cleaning plate is formed on the side wall of the mounting plate, a rotating shaft is rotatably connected in the sliding groove, a fixed sleeve on the rotating shaft is provided with a cam for pushing the cleaning plate to slide out of the sliding groove so that the cleaning plate slides toward the adjacent support bar, and the side of the cleaning plate facing away from the adjacent support bar abuts against the cam;

[0018] The mounting plate is provided with an elastic member for tightening the cleaning plate to abut against the cam, and a locking assembly for locking the rotating shaft is also provided between the mounting plate and the rotating shaft so that the elastic member can lock the cleaning plate on the mounting plate.

[0019] By adopting the above technical solution, after the cleaning plate has scraped the support strip for a long time, if a gap is formed between the cleaning plate and the support strip due to wear, resulting in poor cleaning effect of the cleaning plate on the support strip, the cleaning plate can be adjusted toward the direction close to the adjacent support strip, so as to reduce the gap between the cleaning plate and the adjacent support strip, thereby ensuring the effectiveness of the cleaning plate in cleaning the support strip.

[0020] When the cleaning plate is adjusted toward the direction close to the adjacent support bar, the rotating shaft is rotated, and the cam is driven to rotate when the rotating shaft rotates. Since the side of the cleaning plate facing away from the adjacent support bar abuts against the cam, the cam can push the cleaning plate to slide toward the direction close to the adjacent support bar when it rotates.

[0021] The cam pushes the cleaning plate toward the adjacent support bar until it abuts the adjacent support bar, stopping the rotation of the rotating shaft. At this point, the locking assembly stops the rotating shaft from rotating, and the elastic member locks the cleaning plate to the mounting plate. Once locked to the mounting plate, the cleaning plate can continue to clean the support bar, ensuring that the cleaning plate effectively cleans the support plate.

[0022] Preferably, the elastic member includes a spring arranged in the sliding groove, one end of the spring is fixedly connected to the bottom of the sliding groove, and the other end of the spring is fixedly connected to the cleaning plate. When the cleaning plate abuts against the proximal end of the cam, the spring is in a stretched state.

[0023] By adopting the above technical solution, when the cleaning plate abuts the proximal end of the cam, the spring is in a stretched state, so that the spring's elastic force can always pull the cleaning plate against the cam. When the locking assembly locks the rotating shaft, the cam stops rotating, and the spring's elastic force pulls the cleaning plate tightly against the cam, thereby locking the cleaning plate to the mounting plate.

[0024] Preferably, the locking assembly includes a worm wheel fixedly sleeved on the rotating shaft and a worm rotatably arranged on the mounting plate, and the worm is meshingly connected with the worm wheel.

[0025] By adopting the above technical solution, the rotating shaft is locked by utilizing the self-locking function of the worm wheel and the worm.

[0026] Preferably, a receiving plate for receiving waste is provided in the frame, the receiving plate is located below the mounting seat, and a scraping plate for scraping the receiving plate is provided on the mounting seat, and one end of the scraping plate away from the mounting seat abuts against the receiving plate;

[0027] A waste box for collecting waste is provided at one end of the frame, and a transport component for transporting the waste swept by the scraping plate into the waste box is provided on the frame.

[0028] By adopting the above technical solution, the waste scraped off by the cleaning plate falls onto the carrying plate through the gap, the scraping plate scrapes off the waste on the receiving plate, and the transport component transports the waste scraped off by the scraping plate into the waste box. This allows the waste generated during the cutting process of the laser cutting machine to be collected in the waste box for easy cleaning.

[0029] Preferably, the transport assembly includes a driving wheel rotatably arranged on the frame, a driven wheel rotatably arranged on the frame, and a belt wound between the driving wheel and the driven wheel, the belt is located below the receiving plate, and one end of the belt is located above the waste box.

[0030] By adopting the above technical solution, the belt is located below the receiving plate, so that the waste scraped by the scraping plate can fall onto the belt. One end of the belt is located above the waste box, so that when the belt rotates, the waste dropped on the belt can be transported into the waste box.

[0031] Preferably, the receiving plate is arranged to be tilted upward from an end close to the belt toward an end away from the belt, and a telescopic plate is provided between the mounting seat and the scraping plate for making the scraping plate always abut against the receiving plate.

[0032] By adopting the above technical solution, the carrying plate is arranged upwardly inclined from the end closest to the belt to the end away from the belt, so that when the scraping plate scrapes the waste on the carrying plate, the scraped waste can be affected by gravity and roll down onto the belt. The arrangement of the telescopic plate ensures that the scraping plate always abuts against the receiving plate, thereby enabling the scraping plate to scrape the inclined receiving plate.

[0033] Preferably, a driving gear is fixedly sleeved on the reciprocating screw rod, a driven gear is fixedly sleeved on the axle of the driving wheel, and a chain is wound between the driving gear and the driven gear.

[0034] By adopting the above technical solution, the driving wheel is driven by the cooperation of the driving gear, the driven gear and the chain, so that the driving wheel can rotate synchronously with the reciprocating screw rod.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. During operation of the laser cutting machine in this application, although the waste material cut by the laser cutting gun tends to adhere to the support bars after being melted, the cleaning plate sweeps the support bars. As a result, the gap between two adjacent support bars is not easy to gradually decrease over time. The waste material cut by the laser cutting gun tends to fall through the gap onto the supporting plate, thus preventing the waste material cut by the laser cutting gun from accumulating on the support bars, facilitating the subsequent cutting of workpieces.

[0037] 2. This application uses a scraping plate to scrape the receiving plate, and the waste scraped from the carrying plate falls onto the belt. When the belt rotates, the waste dropped on the belt can be transported into the waste box for easy cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following is combined with Figure 1 -Attached Figure 9 , further details of this application are given.

[0049] A laser cutting machine, referring to Figure 1 and Figure 2 The invention comprises a housing 1 and a frame 2 disposed in the housing 1. The frame 2 is in the shape of a rectangular parallelepiped. A square receiving groove 3 is provided in the frame 2. The receiving groove 3 is provided along the length direction of the frame 2 and passes through the top surface of the frame 2.

[0050] Reference Figure 2 and Figure 3Several support bars 4 are fixedly connected to the top of the frame 2, extending along the width of the frame 2. The support bars 4 are evenly spaced along the length of the frame 2, with gaps 5 formed between adjacent support bars 4 for waste to fall into the frame 2. A laser cutting gun 6 is slidably connected to the frame 2 and is located above the support bars 4.

[0051] Reference Figure 3 and Figure 4 A mounting base 7 is slidably connected within the receiving groove 3. Mounting base 7 is disposed along the length of the frame 2 and is located below the support bar 4. A plurality of mounting plates 8 are fixedly connected to the mounting base 7 and are disposed vertically. Each mounting plate 8 corresponds to each gap 5 and is positioned within the corresponding gap 5.

[0052] Reference Figure 3 and Figure 4 The two opposite side walls of the mounting plate 8 are both provided with a sliding groove 9, in which a cleaning plate 10 for scraping the support strip 4 is slidingly connected, and the cleaning plate 10 is in abutment with the adjacent support strip 4.

[0053] Reference Figure 3 and Figure 4 A rotating shaft 11 is rotatably connected within the sliding groove 9. Two cams 12 are fixedly mounted on the rotating shaft 11, which are used to push the cleaning plate 10 to slide out of the sliding groove 9, causing the cleaning plate 10 to slide toward the adjacent support bar 4. The side of the cleaning plate 10 facing away from the adjacent support bar 4 abuts against the cams 12. In this embodiment, the two cams 12 abut the upper and lower ends of the support bar 4, respectively. The inner wall of the sliding groove 9 is provided with a clearance groove 13 for the cams 12 to rotate.

[0054] Reference Figure 3 and Figure 4 Multiple springs 14 are fixedly connected within the sliding groove 9 to tighten the cleaning plate 10 against the cam 12 and prevent the cleaning plate 10 from falling out of the sliding groove 9. One end of the spring 14 is fixedly connected to the bottom of the sliding groove 9, and the other end of the spring 14 is fixedly connected to the cleaning plate 10. When the cleaning plate 10 abuts the proximal end of the cam 12, the spring 14 is in a stretched state. In this embodiment, the multiple springs 14 are arranged in two rows and symmetrically distributed on both sides of the rotating shaft 11, and the multiple springs 14 are all located between the two cams 12.

[0055] Reference Figure 3 and Figure 4The top of the rotating shaft 11 passes through the mounting plate 8 until it extends out of the mounting plate 8. A worm gear 15 is fixed on the end of the rotating shaft 11 extending out of the mounting plate 8. A worm 16 is rotatably connected to the mounting plate 8 for locking the rotating shaft 11 so that the spring 14 can lock the cleaning plate 10 on the mounting plate 8. The worm 16 is meshed with the worm gear 15.

[0056] Reference Figure 3 and Figure 4 In this embodiment, one end of the worm 16 is also fixedly connected to a knob block 17 for facilitating the rotation of the worm 16 so that the cam 12 can push the cleaning plate 10 to abut against the adjacent support bar 4.

[0057] Reference Figure 3 The two opposing outer walls of the frame 2 are rotatably connected to drive the mounting base 7 to slide along the length of the support bar 4, so that the cleaning plate 10 can scrape the reciprocating screws 18 of the support bar 4. The two reciprocating screws 18 are arranged along the length of the support bar 4. The two reciprocating screws 18 are respectively located at the two ends of the mounting base 7, and the two ends of the mounting base 7 are respectively threadedly connected to the two reciprocating screws 18 in a one-to-one correspondence.

[0058] Reference Figure 3 In this embodiment, two opposing side walls of the frame 2 are provided with a long hole 19 for the mounting seat 7 to pass through and protrude from the frame 2 to facilitate the connection between the mounting seat 7 and the reciprocating screw rod 18. The long hole 19 is opened along the length direction of the reciprocating screw rod 18.

[0059] Reference Figure 2 and Figure 5 The outer wall of the frame 2 is rotatably connected to a connecting rod 20 for connecting the two reciprocating screws 18, so that the rotation of one reciprocating screw 18 can simultaneously drive the other reciprocating screw 18 to rotate in the same direction. The connecting rod 20 is arranged perpendicular to the reciprocating screws 18. The connecting rod 20 is located between the two reciprocating screws 18 and is arranged along the length of the frame 2. Both ends of the connecting rod 20 are fixedly sleeved with a first bevel gear 21. The ends of the two reciprocating screws 18 near the connecting rod 20 are fixedly sleeved with a second bevel gear 22. The two second bevel gears 22 are meshed and connected with the two first bevel gears 21 in a one-to-one correspondence.

[0060] Reference Figure 3 and Figure 5 , let one of the reciprocating screws 18 be the first reciprocating screw 181, and the other reciprocating screw 18 be the second reciprocating screw 182. A drive motor 23 for driving the first reciprocating screw 181 to rotate is fixedly connected to the frame 2, and the output shaft of the drive motor 23 is fixedly connected to the end of the first reciprocating screw 181 away from the second bevel gear 22.

[0061] Reference Figure 5The two outer walls of the frame 2, which are separated from each other, are fixedly connected to guide rails 24 for guiding the mounting seat 7 to slide along the length of the support bar 4. The guide rails 24 are arranged along the length of the support bar 4. Guide sleeves 25 are fixedly connected to both ends of the mounting seat 7. The two guide sleeves 25 slide in a one-to-one correspondence with the two guide rails 24.

[0062] Reference Figure 6 A receiving plate 26 for receiving waste is fixedly connected to the receiving groove 3, and the receiving plate 26 is located below the mounting seat 7. A scraping plate 27 for scraping the receiving plate 26 is provided on the mounting seat 7, and the end of the scraping plate 27 away from the mounting seat 7 abuts against the receiving plate 26.

[0063] Reference Figure 3 and Figure 6 A waste box 28 for collecting waste is placed on the outside of the frame 2, and a mounting groove 29 is opened in the frame 2. The mounting groove 29 is communicated with the accommodating groove 3, and the mounting groove 29 runs through the side of the frame 2 close to the waste box 28. Figure 7 and Figure 8 A driving wheel 30 and a driven wheel 31 are rotatably connected at both ends of the mounting groove 29. A belt 32 is wound between the driving wheel 30 and the driven wheel 31 to transport the waste material scraped by the scraping plate 27 into the waste material box 28. The belt 32 is arranged along the length of the frame 2. The belt 32 is located below the receiving plate 26, and the end of the belt 32 near the waste material box 28 is located above the waste material box 28.

[0064] Reference Figure 6 In this embodiment, the initial position of the mounting seat 7 is located on the side of the frame 2 away from the belt 32.

[0065] Reference Figure 6 In this embodiment, the receiving plate 26 is arranged upwardly inclined from the end closest to the belt 32 toward the end farther from the belt 32. A retractable plate 33 is disposed between the mounting base 7 and the scraping plate 27 to ensure that the scraping plate 27 always abuts against the receiving plate 26. Specifically, the retractable plate 33 includes an outer plate 331 fixedly connected to the mounting base 7 and an inner plate 332 slidably connected to the outer plate 331. The scraping plate 27 is mounted on the inner plate 332, and both the outer plate 331 and the inner plate 332 are arranged vertically.

[0066] Reference Figure 6 and Figure 9The side of the outer plate 331 facing away from the mounting seat 7 is provided with a through slot 34 extending vertically for the sliding movement of the inner plate 332. The inner plate 332 can slide up and down within the through slot 34. The two opposing walls of the through slot 34 each have a retaining groove 35 for retaining the inner plate 332, preventing it from separating from the outer plate 331. The retaining groove 35 does not extend through the bottom wall of the outer plate 331. The two opposing side walls of the inner plate 332 are fixedly connected to retaining blocks 36. Both retaining blocks 36 are located at the top of the inner plate 332 and slideably engage with the two retaining grooves 35 in a one-to-one correspondence.

[0067] Reference Figure 6 and Figure 9 Guide grooves 37 are defined on the two opposing walls of the accommodating groove 3. These grooves are inclined upward from the end closest to the belt 32 toward the end further away from the belt 32, and their inclination angle matches that of the supporting plate. Guide blocks 38 are fixedly connected to the two opposing side walls of the inner rod. These two guide blocks 38 are slidably connected to the two guide grooves 37 in a one-to-one correspondence. As the guide blocks 38 slide within the guide grooves 37, the end of the scraping plate 27 facing away from the mounting seat 7 always abuts the side of the receiving plate 26 facing the mounting seat 7.

[0068] Reference Figure 6 and Figure 9 In addition, a connecting groove 39 for sliding movement of the sweeping plate 27 is defined on the side of the inner plate 332 away from the mounting seat 7. The connecting groove 39 extends vertically. Vertical strip-shaped holes 40 are defined on the two opposing side walls of the inner plate 332. Bolts 41 are fixedly connected to the opposing side walls of the sweeping plate 27. The two bolts 41 correspond to the two strip-shaped holes 40 one by one, and the bolts 41 extend through the corresponding strip-shaped holes 40 to the outside of the inner plate 332.

[0069] Reference Figure 6 and Figure 9 One end of the bolt 41 extending out of the inner plate 332 is threadedly connected to a nut 42 for fixing the scraping plate 27 on the inner plate 332 , and the nut 42 is pressed against the outer wall of the inner plate 332 .

[0070] Reference Figure 5 and Figure 6 A driving gear 43 is fixedly sleeved on the end of the second reciprocating screw rod 182 away from the second bevel gear 22. The axle of the driving wheel 30 passes through the frame 2 until it extends out of the frame 2. A driven gear 44 is fixedly sleeved on the end of the axle of the driving wheel 30 extending out of the frame 2. A chain 45 is wound around the driving gear 43 and the driven gear 44.

[0071] The working principle of the embodiment of the present application is as follows: After each cutting operation, the laser cutting machine of the present application drives the first reciprocating screw 181 to rotate by the drive motor 23. When the first reciprocating screw 181 rotates, the second reciprocating screw 182 is connected by the connecting rod 20 and the first bevel gear 21 and the second bevel gear 22, so that the second reciprocating screw 182 rotates synchronously and in the same direction as the first reciprocating screw 181.

[0072] When the first reciprocating screw 181 and the second reciprocating screw 182 rotate synchronously and in the same direction, the support base slides stably along the length of the support bar 4. When the support base slides along the length of the support bar 4, the cleaning plate 10 scrapes the support bar 4, thereby scraping off the waste adhered to the support bar 4 and dropping it onto the receiving plate 26.

[0073] As the support base slides along the length of the support bar 4, the sliding engagement of the guide blocks 38 and guide slots 37 causes the inner plate 332 to slide along the height of the outer plate 331, ensuring that the scraper plate 27 remains in contact with the support plate. Furthermore, as the support base slides along the length of the support bar 4, the retractable plate 33 drives the scraper plate 27 to also slide along the length of the support bar 4. Because the scraper plate 27 remains in contact with the support plate, as it slides along the length of the support bar 4, it can scrape waste material from the support plate onto the belt 32.

[0074] Because the carrying plate is tilted upward from the end close to the belt 32 to the end away from the belt 32, when the scraping plate 27 scrapes the waste on the carrying plate, the scraped waste can be affected by gravity and roll down onto the belt 32.

[0075] When the second reciprocating screw 182 rotates, the driving wheel 30 is driven by the driving gear 43, the driven gear 44 and the chain 45, so that the driving wheel 30 can rotate synchronously with the second reciprocating screw 182. When the driving wheel 30 rotates, the belt 32 is driven to rotate. When the belt 32 rotates, the waste material that falls onto the belt 32 can be transported into the waste bin 28.

[0076] When the bearing seat slides to the side of the frame 2 near the belt 32 from the initial position, the cleaning plate 10 finishes the cleaning of the support bar 4, and the scraping plate 27 finishes the cleaning of the bearing plate. At this moment, the scraping plate 27 all scrapes the waste material on the bearing plate onto the belt 32.

[0077] When the support base slides back to the initial position from the side of the frame 2 close to the belt 32, the waste materials that fall onto the belt 32 are transported by the belt 32 into the waste box 28. It can be seen that during the operation of the laser cutting machine in the present application, although the waste materials cut by the laser cutting gun 6 are easily adhered to the support bar 4 after being melted, due to the presence of the cleaning plate 10 to scrape the support bar 4, the gap 5 formed between two adjacent support bars 4 is not easy to gradually decrease over time, and the waste materials cut by the laser cutting gun 6 are more likely to fall onto the support plate through the gap 5, thereby making it difficult for the waste materials cut by the laser cutting gun 6 to accumulate on the support bar 4, thereby facilitating the subsequent cutting of workpieces.

[0078] In addition, after the cleaning plate 10 has been scraping the support bar 4 for a long time, if a gap is formed between the cleaning plate 10 and the support bar 4 due to wear, resulting in poor cleaning effect of the cleaning plate 10 on the support plate, the cleaning plate 10 can be adjusted toward the direction close to the adjacent support bar 4, so as to reduce the gap between the cleaning plate 10 and the adjacent support bar 4, thereby ensuring the cleaning effect of the cleaning plate 10 on the support plate.

[0079] When adjusting the cleaning plate 10 toward the adjacent support bar 4, the worm 16 is rotated by means of the knob 17. Since the worm 16 is meshed with the worm gear 15, which is disposed on the rotating shaft 11, the rotation of the worm 16 drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the cam 12 to rotate. Since the cleaning plate 10 is tensioned by the elastic force of the spring 14, the rotation of the cam 12 pushes the cleaning plate 10 toward the adjacent support bar 4.

[0080] Cam 12 pushes cleaning plate 10 toward the adjacent support bar 4 until it abuts the adjacent support bar 4, at which point rotation of knob 17 ceases. At this point, the self-locking function of worm gear 15 and worm 16 prevents rotation of shaft 11, and the elastic force of spring 14 locks cleaning plate 10 to mounting plate 8. Once locked to mounting plate 8, cleaning plate 10 can continue to clean support bar 4, ensuring its effective cleaning of the support plate.

[0081] In addition, after the scraping plate 27 has been scraping the supporting plate for a long time, if a gap is formed between the scraping plate 27 and the supporting plate due to wear, resulting in poor cleaning effect of the scraping plate 27 on the supporting plate, the scraping plate 27 can be adjusted in a direction close to the supporting plate to reduce the gap between the scraping plate 27 and the supporting plate, thereby ensuring the effectiveness of the scraping plate 27 in cleaning the supporting plate.

[0082] To adjust the sweeping plate 27 toward the carrier plate, first rotate the nut 42 away from the inner plate 332 until the nut 42 no longer abuts against the outer wall of the inner plate 332. When the nut 42 no longer abuts against the outer wall of the inner plate 332, pull the sweeping plate 27 toward the carrier plate and slide it until it abuts against the carrier plate.

[0083] After the scraper plate 27 abuts the carrier plate, the nut 42 is rotated toward the inner plate 332 until the nut 42 abuts against the outer wall of the inner plate 332, thereby securing the scraper plate 27 to the inner plate 332. Once secured to the inner plate 332, the scraper plate 27 can continue to clean the carrier plate, ensuring that the scraper plate 27 effectively cleans the carrier plate.
