Description

Technical Field

[0001] This invention belongs to the field of galvanized steel strip shearing technology, specifically, it relates to a longitudinal and transverse shearing device and shearing method for galvanized steel strip. Background Technology

[0002] Galvanized steel strip is a metallic material made by coating a layer of zinc or zinc-aluminum alloy onto the surface of cold-rolled or hot-rolled long steel plates through hot-dip galvanizing or electroplating. It combines the strength of steel strip with the corrosion resistance of zinc layer and is widely used in many fields. Longitudinal and transverse shearing equipment, or slitting and cutting units for short, is a core piece of equipment in the field of metal sheet processing. It is mainly used to cut wide metal coils into narrow coils or fixed-length plates to meet the specification requirements of different downstream industries. Longitudinal and transverse shearing equipment is required during the processing of galvanized steel strip.

[0003] In existing galvanized strip shearing equipment and methods, the galvanized strip is typically sheared into narrow strips using a longitudinal shearing blade. These narrow strips are then conveyed to a transverse shearing blade via conveyor rollers. However, during longitudinal shearing, the friction and pressure between the blade and the strip surface cause zinc dross particles to peel off, exposing the dross at the cut or surface. As the dross passes through the conveyor rollers, it is pressed into the roller surface due to friction, forming a stronger adhesion. This causes the rotating conveyor rollers and dross to scratch the galvanized layer, resulting in uneven scratches, indentations, or zinc dross adhesion marks on the surface. This damages the surface smoothness and gloss, reduces the yield rate of galvanized strip processing, and diminishes the effectiveness of the galvanized strip shearing equipment and methods. Summary of the Invention The purpose of this invention is to provide a longitudinal and transverse shearing device and shearing method for galvanized steel strip, which solves the technical problem in related technologies where zinc dross from the conveying rollers during the conveying of galvanized steel strips scratches the galvanized layer and reduces the yield of galvanized steel strip processing.

[0004] According to one aspect, at least one embodiment of the present invention provides a longitudinal and transverse shearing device for galvanized strip steel, comprising: a shearing table, a longitudinal shearing structure disposed on one side of the upper end of the shearing table, and a transverse shearing structure disposed on the other side of the upper end of the shearing table. The shearing table is provided with a conveying mechanism, which smoothly conveys the galvanized strip steel after longitudinal shearing to the transverse shearing structure. The conveying mechanism includes a conveying groove formed on the upper end of the shearing table and a plurality of conveying rollers rotatably disposed inside the conveying groove for conveying the galvanized strip steel. The shearing table is provided with a rotating structure for controlling the plurality of conveying rollers to rotate in the same direction. The roller surfaces of the conveying rollers are provided with spiral guide grooves. A negative pressure chamber is built into the conveying rollers to cooperate with the spiral guide grooves. A plurality of micro-holes are formed along the spiral guide grooves on the conveying rollers. A negative pressure fan communicating with the negative pressure chamber is installed on the outer surface of the shearing table. Several first guide troughs matching the spiral guide troughs are provided on the side of the feeding trough near the negative pressure fan. The shearing processing table is provided with a first collection box aligned with the first guide troughs, which is used to collect the zinc dross cleaned from the spiral guide troughs in the conveying roller. When the galvanized strip passes through the roller surface of the conveying roller, due to the negative pressure, the zinc dross adhering to the surface of the galvanized strip and the roller surface of the conveying roller is adsorbed by micropores. Under the action of negative pressure, the zinc dross detaches from the surface of the galvanized strip and enters the spiral guide trough. This process is very rapid and can usually be completed within 0.1 seconds. The rotation of the conveying roller drives the zinc dross in the spiral guide trough to move towards the roller end of the conveying roller. The design of the spiral guide trough ensures that the zinc dross will not re-adhere to the roller surface during the movement. At the same time, the continuous negative pressure ensures that the zinc dross always stays in the spiral guide trough and will not jump out. When the zinc dross is conveyed to the roller end of the conveying roller, it leaves the negative pressure area and falls into the first collection box under the action of gravity.

[0005] According to an exemplary embodiment of this disclosure, the longitudinal shearing structure includes a longitudinal shearing frame mounted on a shearing processing table and cutter rollers symmetrically mounted on the longitudinal shearing frame. The cutter rollers are provided with a plurality of longitudinal shearing tools for longitudinally shearing galvanized strip steel. The transverse shearing structure includes a transverse shearing frame mounted on a shearing processing table and a cutter holder movably mounted on the transverse shearing frame. The cutter holder is equipped with transverse shearing tools for transversely shearing a plurality of galvanized strip steel.

[0006] According to an exemplary embodiment of this disclosure, the micropores connect the spiral guide channel and the negative pressure chamber. The micropores are configured as inverted conical counterbore holes. The number of micropores on the spiral guide channel near the first guide channel gradually decreases, which facilitates the conveying of zinc dross into the first guide channel. The shearing processing table is equipped with a weight sensor that works in conjunction with the first collection box. When the amount of zinc dross in the first collection box reaches a set amount, the weight sensor will trigger an alarm to remind the operator to clean it.

The rotating block is provided with a first synchronous belt structure, and a plurality of the first synchronous belt structures drive two adjacent rotating blocks to connect. One end of the rotary motor is coaxially connected to a rotating block, so that the rotating block and the first synchronous belt structure control a plurality of conveying rollers to rotate.

One end of the first rotating rod is provided with a second synchronous belt structure. One end of the second synchronous belt structure is coaxially connected to the rotating block. The second synchronous belt structure is inclined, so that the rotation of the rotating block drives the elastic brush roller to rotate through the second synchronous belt structure, cleaning off large zinc dross particles on the galvanized steel strip and reducing the total amount of zinc dross entering the conveying roller from the source. The bottom surface of the conveying trough is provided with a second guide trough for use with the elastic brush roller. The inner bottom surface of the second guide trough is inclined, and the second guide trough can guide the collected large zinc dross particles into the first collection box.

[0009] According to an exemplary embodiment of this disclosure, the conveying mechanism further includes a plurality of sealing end caps installed on the conveying rollers and a guide box rotatably connected to the sealing end caps.

When the moving part moves downward, the second connecting block and the second moving rack, through the second moving gear and the first moving gear, cause the first moving rack to control the first guide slide to move, so that the sealing block opens the moving groove. When the moving part moves away, the first connecting block and the second moving rack, through the second moving gear and the first moving gear, cause the first moving rack to control the first guide slide to move, so that the sealing block closes the moving groove, thereby reducing the entry of impurities into the moving groove. When the first moving block moves, the second moving block is aligned and fitted with the sealing block, and can move, thereby improving the sealing effect of the sealing assembly.

[0015] According to an exemplary embodiment of this disclosure, the first discharge trough is provided with a second cleaning assembly for cleaning the cleaning scraper. The second cleaning assembly includes a plurality of nozzles symmetrically arranged in the first discharge trough and a plurality of support seats rotatably connected to the nozzles. A filter cover is detachably installed in the air outlet of each nozzle. An air guide pipe is connected to the bottom end of each nozzle. The second cleaning assembly also includes an air storage tank disposed in a guide box and communicating with the air guide pipe. A piston rod for pressing gas into the nozzles through the air guide pipe is movably disposed in the air storage tank. A pressing block is provided at the top end of the piston rod. When the cleaning scraper and the moving part move to the pressing block, the piston rod controls the nozzles to perform cleaning work. A return spring is sleeved on the piston rod. The return spring is connected to the pressing block. When the cleaning scraper and the moving part leave the pressing block, the return spring causes the piston rod to return to its original position.

[0016] According to an exemplary embodiment of this disclosure, the second cleaning assembly further includes a second rotating rod symmetrically arranged on the outer wall of the nozzle component. One end of the second rotating rod extends into the support base. The second cleaning assembly also includes a second rotating gear arranged in the support base and coaxially connected to the second rotating rod, and a second transmission gear meshing with the second rotating gear.

When the main rack moves down, the adjusting gear controls the second rotating rod to adjust the angle of the nozzle component through the second transmission gear and the second rotating gear, so that several nozzle components clean the cleaning brush from multiple angles.

[0017] According to an exemplary embodiment of this disclosure, a second collection box is detachably installed at the lower end of the guide box and sealed to the first discharge trough. The second collection box has a collection cavity for collecting impurities. The bottom end of the second collection box has a second discharge trough aligned with the first collection box.

The sealing assembly can control the sealing plates to open or close the second discharge trough.

[0018] According to an exemplary embodiment of this disclosure, the sealing assembly includes a fixing strip symmetrically arranged on a first collection box, a first rack disposed on the upper end of the fixing strip, and a second rack disposed on one side of the first rack.

[0019] According to an exemplary embodiment of this disclosure, one end of the first gear is provided with a second transmission rod coaxially connected to the third moving gear. When the first gear rotates, the third moving gear is controlled to rotate through the second transmission rod, thereby controlling the sealing plate to move through the third moving gear and the third moving rack.

[0020] According to an exemplary embodiment of this disclosure, the second gear is coaxially provided with a third transmission gear via a second transmission rod. The third transmission gear meshes with a third moving gear, so that when the second gear rotates, the third transmission gear controls the third moving rack to move via the third moving gear, thereby controlling the sealing plate to move. When the two sealing plates move, the second discharge chute is opened or closed.

[0021] According to one aspect, at least one embodiment of the present invention provides a method for longitudinal and transverse shearing of galvanized steel strip, comprising the following steps: S1. The shearing processing table longitudinally shears galvanized strip steel into several narrow strips through the longitudinal shearing structure, and then conveys the narrow strips to the transverse shearing structure for transverse shearing through the conveying mechanism. S2. During the conveying process, the rotating structure drives the elastic brush roller to rotate through the second synchronous belt structure to clean the zinc dross from the narrow strip steel. The rotating structure drives several conveying rollers to rotate in the same direction. The negative pressure fan and the conveying rollers work together to adsorb the zinc dross on the surface of the narrow strip steel and the roller surface of the conveying rollers through micropores and collect it in the spiral guide groove. S3. During the shearing process, when the zinc dross in the first collection box reaches the set amount, the weight sensor triggers an alarm, disassembles and cleans the first collection box, and drives the screw transmission structure through the main gear and lifting gear to make the moving parts drive the cleaning scraper to move up and down along the filter plate to clean the impurities intercepted by the filter plate. S4. When the screw drive structure is running, the first transmission gear and the first transmission rack drive the second guide slide to move, so that the sealing strip opens the second connecting groove, and control the cleaning scraper to move to the lower part of the guide box. The piston rod, air tank and nozzle cooperate to spray the cleaning scraper from multiple angles. After cleaning, the cleaning scraper is reset and the sealing strip re-seals the second connecting groove. S5. Impurities cleaned by the cleaning scraper fall into the first collection box through the second collection box. When the first collection box is disassembled and cleaned, the fixing strip drives the first and second racks to control the sealing plate to close the second collection box. When the first collection box is reset, the sealing plate is controlled by the third moving rack to open the second discharge chute, so that the second collection box and the first collection box are connected to collect impurities.

[0022] The beneficial effects of the embodiments disclosed herein are as follows: (1) The galvanized strip steel longitudinal and transverse shearing equipment provided in this embodiment of the invention uses a shearing processing table, a conveying trough, a conveying roller, a rotating structure, a spiral guide trough, a negative pressure fan and a first collection box to quickly adsorb zinc dross on the surface of the strip steel and the roller surface, avoiding zinc dross from being pressed into the surface of the strip steel and causing scratches, thus improving the processing quality of the longitudinal and transverse shearing equipment. The rotational power of the conveying roller drives the zinc dross to move towards the roller end, and the zinc dross will not adhere to the roller surface again during the movement. The first guide trough and the first collection box are used to realize the directional collection of zinc dross, reducing the interference of zinc dross on the subsequent transverse shearing process from the source. The elastic brush roller, the second synchronous belt structure and the conveying roller are driven together to clean in advance. Large-particle zinc dross reduces the total amount of zinc dross entering the negative pressure cleaning system, improving the efficiency of negative pressure cleaning. A filter plate is installed inside the feed box to intercept impurities sucked in by the negative pressure. A screw drive structure drives a cleaning scraper to move up and down along the filter plate, automatically cleaning impurities from the filter plate surface and ensuring smooth airflow in the negative pressure system. The moving parts are linked to the sealing components; the moving part automatically opens the moving groove when moving and automatically closes the groove after moving, reducing the entry of external impurities into the equipment. The sealing effect of the feed box is improved through sealing strips, a second guide slide, a first transmission rack, a first transmission gear, a first rotating gear, and a main rack, enhancing the performance of the longitudinal and transverse shearing equipment.

[0023] (2) The galvanized strip steel longitudinal and transverse shearing equipment provided in this embodiment of the invention uses a nozzle, support base, filter cover, air guide pipe, air tank, piston rod and return spring to clean the cleaning brush. The main rack, second rotating gear, second transmission gear, adjusting gear and first transmission rod work together to adjust the angle of the nozzle and improve the cleaning effect of the cleaning brush. The second collection box, sealing plate, fixing strip, first rack, second rack, first gear, second gear, third moving rack, third moving gear, second transmission rod and third transmission gear are set to make the second collection box and the first collection box work together to realize the automatic sealing and opening of the guide box and the second collection box. This ensures the collection effect of impurities and prevents external dust from entering the equipment and contaminating the transmission components, extending the equipment maintenance cycle, ensuring the continuity of zinc dross collection, avoiding zinc dross leakage during the cleaning process, and improving the use effect of the longitudinal and transverse shearing equipment.

[0024] (3) The shearing method used in this invention forms an integrated processing flow of shearing, conveying, cleaning and collection. Large zinc dross particles are cleaned in advance by the elastic brush roller. During the conveying process, the combination of negative pressure and spiral guide groove is used to quickly adsorb the fine zinc dross on the surface of the strip steel and the surface of the conveying roller, so as to avoid the zinc dross being pressed into the surface of the strip steel and forming defects such as scratches and pits. This ensures the flatness and smoothness of the strip steel surface after shearing. The longitudinal shearing, conveying and transverse shearing processes are seamlessly connected. The rotating structure is linked to the conveying roller and the elastic brush roller by the synchronous belt, without the need for an additional power source. The cleaning components and filter plates intercept impurities drawn in by negative pressure. Combined with the automatic cleaning of the cleaning brush, a three-stage impurity treatment process of coarse cleaning, fine cleaning, and interception cleaning is implemented to achieve complete collection of zinc dross throughout the shearing process. The second collection box is linked with the first collection box, collecting filtered and scraped impurities into the first collection box, achieving unified collection and recycling of zinc dross, reducing the difficulty of subsequent environmental sorting and processing. When the first collection box is disassembled, the sealing plate automatically closes the outlet of the second collection box to prevent impurity leakage and secondary pollution, thereby improving the effectiveness of the shearing method.

[0036] Example 1 like Figures 1 to 13The diagram illustrates a galvanized strip longitudinal and transverse shearing device and method according to an embodiment of the present invention. It includes a shearing table 1, a longitudinal shearing structure 2 disposed on one side of the upper end of the shearing table 1, and a transverse shearing structure 3 disposed on the other side of the upper end of the shearing table 1. A conveying mechanism is provided on the shearing table 1 to smoothly convey the galvanized strip after longitudinal shearing to the transverse shearing structure 3. The conveying mechanism includes a conveying trough 4 opened on the upper end of the shearing table 1 and several conveying rollers 5 rotatably disposed inside the conveying trough 4 to convey the galvanized strip. A rotating structure 6 is provided on the shearing table 1 to control the several conveying rollers 5 to rotate in the same direction. A spiral guide groove 7 is opened on the roller surface of the conveying rollers 5. A negative pressure chamber is built into the conveying rollers 5 to cooperate with the spiral guide groove 7. Several micro-holes are opened along the spiral guide groove 7 on the conveying rollers 5. A negative pressure fan 8 connected to the negative pressure chamber is installed on the outer surface of the shearing table 1. The conveying trough 4 is located near... Several first guide troughs matching the spiral guide troughs 7 are provided on one side of the negative pressure fan 8. The shearing processing table 1 is provided with a first collection box 9 aligned with the first guide troughs, which is used to collect the zinc dross cleaned by the spiral guide troughs 7 in the conveying roller 5. When the galvanized strip passes through the roller surface of the conveying roller 5, due to the negative pressure, the zinc dross adhering to the surface of the galvanized strip and the roller surface of the conveying roller 5 is adsorbed by micropores. Under the action of negative pressure, the zinc dross detaches from the surface of the galvanized strip and enters the spiral guide trough 7. This process is very fast and can usually be completed within 0.1 seconds. The rotation of the conveying roller 5 drives the zinc dross in the spiral guide trough 7 to move towards the roller end of the conveying roller 5. The design of the spiral guide trough 7 ensures that the zinc dross will not re-adhere to the roller surface during the movement. At the same time, the continuous negative pressure ensures that the zinc dross always stays in the spiral guide trough 7 and will not jump out. When the zinc dross is conveyed to the roller end of the conveying roller 5, it leaves the negative pressure area and falls into the first collection box 9 under the action of gravity.

[0037] Further, the longitudinal shearing structure 2 is activated to longitudinally shear the galvanized strip steel, and the conveying mechanism is activated to transport the longitudinally sheared galvanized strip steel. The rotating structure 6 is activated to drive several conveying rollers 5 to transport the longitudinally sheared galvanized strip steel, and the negative pressure fan 8 is activated so that the zinc dross adhering to the surface of the galvanized strip steel and the roller surface of the conveying roller 5 is adsorbed by micropores. Under the action of negative pressure, the zinc dross is removed from the surface of the galvanized strip steel and enters the spiral guide groove 7. The rotation of the conveying roller 5 drives the zinc dross in the spiral guide groove 7 to move towards the roller end of the conveying roller 5. When the zinc dross is transported to the roller end of the conveying roller 5, it leaves the negative pressure area and falls into the first collection box 9 under the action of gravity. The conveying mechanism transports the longitudinally sheared galvanized strip steel to the transverse shearing structure 3, and the transverse shearing structure 3 is activated to transversely shear the galvanized strip steel.

[0038] As a specific example, such as Figure 1 and Figure 2As shown, the longitudinal shearing structure 2 includes a longitudinal shearing frame 62 mounted on the shearing processing table 1 and two cutter rollers 63 symmetrically mounted on the longitudinal shearing frame 62. The two cutter rollers 63 are respectively located on the upper and lower sides of the galvanized strip steel. The cutter rollers 63 are provided with a plurality of longitudinal shearing tools 64 for longitudinally shearing the galvanized strip steel. The transverse shearing structure 3 includes a transverse shearing frame 65 mounted on the shearing processing table 1 and a cutter holder 66 movably mounted on the transverse shearing frame 65. The cutter holder 66 is equipped with transverse shearing tools 67 for transversely shearing a plurality of galvanized strip steel.

[0039] Furthermore, the cutter roller 63 is controlled to rotate, causing the cutter roller 63 to drive the longitudinal shear 64 to rotate, so that the longitudinal shear 64 performs longitudinal shearing on the galvanized strip steel. The cutter holder 66 is controlled to move downward, so that the cutter holder 66 drives the transverse shear 67 to move downward, so that the transverse shear 67 performs transverse shearing on several galvanized strip steels.

[0040] As a specific example, such as Figure 3 As shown, the micropores connect the spiral guide channel 7 to the negative pressure chamber. The micropores are set as inverted conical counterbore holes. The number of micropores on the side of the spiral guide channel 7 near the first guide channel gradually decreases, which facilitates the conveying of zinc dross to the first guide channel. The shearing processing table 1 is equipped with a weight sensor that works in conjunction with the first collection box 9. When the zinc dross in the first collection box 9 reaches the set amount, the weight sensor alarm will be triggered to remind the operator to clean it.

[0041] As a specific example, such as Figure 4 As shown, the rotating structure 6 includes a rotating motor 10 mounted on the outer surface of the shearing table 1 and a rotating block 11 connected to the other end of the conveying roller 5. The rotating block 11 is provided with a first synchronous belt structure 12. Several first synchronous belt structures 12 drive and connect two adjacent rotating blocks 11. One end of the rotating motor 10 is coaxially connected to a rotating block 11, so that the rotating block 11 and the first synchronous belt structure 12 control several conveying rollers 5 to rotate.

[0042] Furthermore, the rotary motor 10 is started, which drives the rotating block 11 to rotate, so that the rotating block 11 drives the first synchronous belt structure 12 to rotate, the first synchronous belt structure 12 drives the adjacent rotating block 11 to rotate, and the rotating block 11 drives the conveying roller 5 to rotate when it rotates.

[0043] As a specific example, such as Figure 3 and Figure 4As shown, the conveying trough 4 is provided with an elastic brush roller 13 for pre-cleaning the galvanized strip steel and a cleaning scraper 14 located below the elastic brush roller 13 on the side near the longitudinal shearing structure 2. One end of the elastic brush roller 13 is provided with a first rotating rod that extends into the shearing processing table 1. One end of the first rotating rod is provided with a second synchronous belt structure 15. One end of the second synchronous belt structure 15 is coaxially connected to the rotating block 11. The second synchronous belt structure 15 is inclined, so that the rotation of the rotating block 11 drives the elastic brush roller 13 to rotate through the second synchronous belt structure 15, cleaning off the large zinc dross particles on the galvanized strip steel and reducing the total amount of zinc dross entering the conveying roller 5 from the source. The bottom surface of the conveying trough 4 is provided with a second guide trough that works in conjunction with the elastic brush roller 13. The inner bottom surface of the second guide trough is inclined, and the second guide trough can guide the collected large zinc dross particles into the first collection box 9.

[0044] Furthermore, the rotary motor 10 drives the rotating block 11 to rotate, so that the rotating block 11 drives the adjacent rotating block 11 to rotate through the first synchronous belt structure 12. The rotating block 11 drives the second synchronous belt structure 15 to rotate, so that the second synchronous belt structure 15 drives the elastic brush roller 13 to rotate through the first rotating rod. The elastic brush roller 13 cleans the galvanized steel strip in advance, removing large zinc dross particles from the galvanized steel strip. The cleaning scraper 14 cleans the elastic brush roller 13, and the removed large zinc dross particles enter the first collection box 9 through the second guide chute.

[0045] As a specific example, such as Figure 3 and Figure 5 - Figure 6 As shown, the conveying mechanism also includes several sealing end caps 16 installed on the conveying roller 5 and guide boxes 17 rotatably connected to the sealing end caps 16. One end of the guide box 17 is in close contact with the negative pressure fan 8. A filter plate 18 is vertically installed in the guide box 17. The filter plate 18 can intercept external impurities to prevent impurities from entering the negative pressure chamber.

[0046] As a specific example, such as Figure 6 and Figure 7As shown, the conveying mechanism also includes a first cleaning component that is movably disposed in the guide box 17 and cleans the filter plate 18. The first cleaning component includes cleaning scrapers 19 symmetrically disposed on both sides of the filter plate 18 and in contact with the filter plate 18, and a screw drive structure 20 symmetrically disposed in the guide box 17 and controlling the cleaning scrapers 19 to move up and down. The screw drive structure 20 is provided with a moving part 21 connected to the cleaning scraper 19. The inner wall of the guide box 17 is symmetrically provided with several moving grooves that fit with the moving part 21. The first cleaning component also includes a lifting gear 22 disposed on the upper inner side of the guide box 17 and connected to the screw drive structure 20, and a main gear 23 that controls the rotation of the lifting gear 22. The main gear 23 is connected to the output shaft of the drive motor 24, so that the drive motor 24, through the main gear 23 and the lifting gear 22, causes the screw drive structure 20 to control the cleaning scrapers 19 to clean impurities from the filter plate 18.

[0047] Furthermore, the negative pressure fan 8 is started, causing the filter plate 18 to intercept external impurities. Every once in a while, the drive motor 24 is started, driving the main gear 23 to rotate, which in turn drives the lifting gear 22 to rotate, which in turn drives the screw transmission structure 20 to work, which in turn drives the moving part 21 to move, which in turn drives the cleaning scraper 19 to move up and down, so that the cleaning scraper 19 cleans the filter plate 18.

[0048] As a specific example, such as Figure 6 - Figure 7 and Figure 11 - Figure 13 As shown, the movable component 21 includes a first movable block 25 that fits into the movable groove and a second movable block 26 that is symmetrically and movably arranged on the upper and lower sides of the first movable block 25. The first movable block 25 has a first connecting groove that fits into the second movable block 26. Several guide rods 27 that are inserted into the second movable block 26 are vertically arranged in the first connecting groove. Support springs 28 that are respectively connected to the first movable block 25 and the second movable block 26 are sleeved on the guide rods 27. A sealing component that works with the movable component 21 is provided in the movable groove. The sealing component can seal the movable groove and reduce the entry of external impurities into the interior of the movable groove.

[0049] As a specific example, such as Figure 11 - Figure 13As shown, the sealing assembly includes several sealing blocks 68 symmetrically arranged in the movable groove and a first guide slide 29 arranged on one side of the sealing block 68. The sealing blocks 68 and the moving part 21 seal the movable groove. The first guide slide 29 is provided with a first moving rack 30. The guide box 17 is provided with a first moving gear 31 that meshes with the first moving rack 30. The sealing assembly also includes a second moving gear 32 coaxially connected to the first moving gear 31 and two second moving racks 33 symmetrically arranged with the second moving gear 32. The two second moving racks 33 are respectively arranged on both sides of the second moving gear 32 and mesh with the second moving gear 32, so that the two second moving racks 33 can respectively control the second moving gear 32 to rotate clockwise and counterclockwise. The upper part of one side of the outer surface of the first moving block 25 is symmetrically provided with a first connecting block connected to the second moving rack 33. The lower part of one side of the outer surface of the first moving block 25 is provided with a first connecting block. The first connecting block and the second moving rack 33 are symmetrically arranged. The lengths of the first connecting block and the second connecting block are different, so that the second moving rack 33 connected to them are respectively arranged on both sides of the second moving gear 32. When the moving part 21 moves downward, the second connecting block and the second moving rack 33, through the second moving gear 32 and the first moving gear 31, cause the first moving rack 30 to control the first guide slide 29 to move, so that the sealing block 68 opens the moving groove. After the moving part 21 moves away, the first connecting block and the second moving rack 33, through the second moving gear 32 and the first moving gear 31, cause the first moving rack 30 to control the first guide slide 29 to move, so that the sealing block 68 closes the moving groove, thereby reducing the entry of impurities into the moving groove. When the first moving block 25 moves, the second moving block 26 is aligned and fitted with the sealing block 68 and can move, thereby improving the sealing effect of the sealing assembly.

[0050] Furthermore, when the movable component 21 moves, the first movable block 25 drives the second movable block 26 to move towards the sealing block 68, causing the second connecting block to drive the second movable rack 33 to mesh with the second movable gear 32, causing the second movable gear 32 to drive the first movable gear 31 to rotate, the first movable gear 31 to drive the first movable rack 30 to move, and the first movable rack 30 to drive the first guide slide 29 to move, causing the sealing block 68 to open the moving groove. After the movable component 21 moves away, the first connecting block controls the second movable gear 32 and the first movable gear 31 to rotate through the second movable rack 33, causing the first movable rack 30 to control the first guide slide 29 to move, causing the sealing block 68 to close the moving groove. When the second movable block 26 moves, the support spring 28 extends and retracts.

[0051] Example 2 Based on Example 1, referring to Figure 5 - Figure 13This is the second embodiment of the present invention.

[0052] As a specific example, such as Figure 5 and Figure 6 As shown, the filter plate 18 extends into the lower inner part of the guide box 17. The lower end face of the guide box 17 is provided with a first discharge groove aligned with the first collection box 9. The guide box 17 is provided with a second connecting groove communicating with the first discharge groove. A sealing strip 34 is movably provided in the second connecting groove. The size of the sealing strip 34 is larger than the size of the cleaning brush 19. The sealing strip 34 seals the second connecting groove to prevent external impurities from entering the second connecting groove. The lower end of the filter plate 18 is provided with a scraping part for the cleaning brush 19, which can scrape and clean the impurities on the cleaning brush 19.

[0053] As a specific example, such as Figure 6 and Figure 8 As shown, the sealing strip 34 has second guide slides 35 on both sides of its outer surface. The second guide slides 35 have first transmission racks 36. The guide box 17 has a first transmission gear 37 that meshes with the first transmission rack 36. The first transmission gear 37 has a first rotating gear 38 coaxially mounted on it. The diameter of the first rotating gear 38 is smaller than that of the first transmission gear 37. The screw drive structure 20 has a main rack 39 that is aligned with the first rotating gear 38. The main rack 39 can mesh with the first rotating gear 38. When the screw drive structure 20 controls the main rack 39 to move to the first rotating gear 38, the first rotating gear 38 controls the first transmission rack 36 to move through the first transmission gear 37. This causes the second guide slides 35 to control the sealing strip 34 to open the second connecting groove, making it easier for the cleaning scraper 19 to enter the second connecting groove.

[0054] Furthermore, when the filter plate 18 moves downward, the lead screw transmission structure 20 drives the main rack 39 to move, the main rack 39 drives the first rotating gear 38 to rotate, the first rotating gear 38 drives the first transmission gear 37 to rotate, the first transmission gear 37 drives the first transmission rack 36 to move, the first transmission rack 36 controls the second guide slide 35 to move, so that the second guide slide 35 controls the sealing strip 34 to open the second connecting groove, so that the cleaning scraper 19 can enter the second connecting groove.

[0055] As a specific example, such as Figure 6 and Figure 9 - Figure 10As shown, a second cleaning assembly for cleaning the cleaning brush 19 is provided in the first discharge trough. The second cleaning assembly includes several nozzles 40 symmetrically arranged in the first discharge trough and several support seats 41 rotatably connected to the nozzles 40. A filter cover 42 is detachably installed in the air outlet of the nozzle 40. An air guide pipe 43 is connected to the bottom end of the nozzle 40. The second cleaning assembly also includes an air storage tank 44 disposed in the guide box 17 and connected to the air guide pipe 43. A piston rod 45 for pressing gas into the nozzle 40 through the air guide pipe 43 is movably disposed in the air storage tank 44. A pressing block is provided at the top of the piston rod 45. When the cleaning brush 19 and the moving part 21 move to the pressing block, the piston rod 45 controls the nozzle 40 to perform cleaning work. A return spring 46 is sleeved on the piston rod 45 and connected to the pressing block. When the cleaning brush 19 and the moving part 21 leave the pressing block, the return spring 46 causes the piston rod 45 to return to its original position.

[0056] Furthermore, when the cleaning scraper 19 and the moving part 21 move to the squeezing block, the squeezing block causes the piston rod 45 to move downward, so that the piston rod 45 forces the gas in the gas storage tank 44 into the nozzle 40 through the air guide pipe 43, so that the nozzle 40 sprays air to clean the cleaning scraper 19. When the cleaning scraper 19 and the moving part 21 leave the squeezing block, the return spring 46 causes the piston rod 45 to return to its original position, so that the piston rod 45 draws external gas into the gas storage tank 44 through the nozzle 40 and the air guide pipe 43, and the filter cover 42 filters impurities from the drawn-in gas.

[0057] As a specific example, such as Figure 9 and Figure 10 As shown, the second cleaning assembly also includes a second rotating rod symmetrically arranged on the outer wall of the nozzle 40. One end of the second rotating rod extends into the support base 41. The second cleaning assembly also includes a second rotating gear 47 arranged in the support base 41 and coaxially connected to the second rotating rod, and a second transmission gear 48 meshing with the second rotating gear 47. The guide box 17 has a rotating groove matching the second transmission gear 48. One end of the second transmission gear 48 extends into the rotating groove. An adjusting gear 49 meshing with the second transmission gear 48 is rotatably arranged in the rotating groove. The adjusting gear 49 is aligned with the main rack 39. A first transmission rod 50 is provided between adjacent adjusting gears 49. When the main rack 39 moves down, the adjusting gear 49 controls the second rotating rod to adjust the angle of the nozzle 40 through the second transmission gear 48 and the second rotating gear 47, so that several nozzles 40 can perform multi-angle cleaning on the cleaning scraper 19.

[0058] Furthermore, when the main rack 39 moves downward, the main rack 39 drives the adjusting gear 49 to rotate, which in turn drives the second transmission gear 48 to rotate, which in turn drives the second rotating gear 47 to rotate, which in turn drives the nozzle component 40 to rotate on the support base 41 via the second rotating rod, thereby adjusting the angle of the nozzle component 40.

[0059] Example 3 Based on Example 2, referring to Figure 5 - Figure 15 This is the third embodiment of the present invention.

[0060] As a specific example, such as Figure 5 and Figure 14 As shown, a second collection box 51, which is sealed to the first discharge trough, is detachably installed at the lower end of the guide box 17. The second collection box 51 has a collection chamber for collecting impurities. The bottom end of the second collection box 51 has a second discharge trough aligned with the first collection box 9. A sealing plate 52 is movably and symmetrically arranged in the second discharge trough. The two sealing plates 52 are staggered and cooperate to seal the second discharge trough. The second collection box 51 has a sealing assembly that is drivenly connected to the first collection box 9. The sealing assembly can control the sealing plate 52 to open or close the second discharge trough.

[0061] Furthermore, when the first collection box 9 is disassembled and cleaned, the sealing assembly controls the sealing plate 52 to close the second discharge chute.

[0062] As a specific example, such as Figure 14 and Figure 15 As shown, the sealing assembly includes a fixing strip 53 symmetrically arranged on the first collection box 9, a first rack 54 arranged on the upper end of the fixing strip 53, and a second rack 55 arranged on one side of the first rack 54. When the first collection box 9 moves, the fixing strip 53, the first rack 54, and the second rack 55 control the movement of the two sealing plates 52. The position of the second rack 55 is higher than the position of the first rack 54. A first gear 56 and a second gear 57 are symmetrically rotatably arranged in the second collection box 51. The diameter of the first gear 56 is larger than the diameter of the second gear 57. The first gear 56 meshes with the first rack 54, and the second gear 57 meshes with the second rack 55. The sealing assembly also includes a third moving rack 58 symmetrically arranged on the lower end of the sealing plate 52 and a third moving gear 59 meshing with the third moving rack 58. The bottom end face of the sealing plate 52 has a rack groove for installing the third moving rack 58. The third moving gear 59 is rotatably arranged in the second collection box 51.

[0063] Furthermore, when the first collection box 9 moves, it drives the fixing bar 53 to move, which in turn drives the first rack 54 and the second rack 55 to move. The first rack 54 drives the first gear 56 to rotate, and the second rack 55 drives the second gear 57 to rotate. The first gear 56 and the second gear 57 then drive the two third moving gears 59 to rotate, which in turn drive the third moving rack 58 to move, and the third moving rack 58 drives the sealing plate 52 to rotate.

[0064] As a specific example, such as Figure 15 and Figure 15 As shown, one end of the first gear 56 is provided with a second transmission rod 60 coaxially connected to the third moving gear 59. When the first gear 56 rotates, the second transmission rod 60 controls the third moving gear 59 to rotate, thereby controlling the sealing plate 52 to move through the third moving gear 59 and the third moving rack 58.

[0065] Furthermore, when the first gear 56 rotates, it causes the second transmission rod 60 to drive the third moving gear 59 to rotate, and the third moving gear 59 and the third moving rack 58 control the movement of the sealing plate 52.

[0066] As a specific example, such as Figure 14 and Figure 15 As shown, the second gear 57 is coaxially provided with a third transmission gear 61 via the second transmission rod 60. The third transmission gear 61 meshes with the third moving gear 59, so that when the second gear 57 rotates, the third transmission gear 61 controls the third moving rack 58 to move through the third moving gear 59, thereby controlling the sealing plate 52 to move. When the two sealing plates 52 move, the second discharge chute is opened or closed.

[0067] Furthermore, when the second gear 57 rotates, it drives the second transmission rod 60 to rotate, which in turn drives the third transmission gear 61 to rotate. The third transmission gear 61 drives the third moving gear 59 to rotate, which in turn controls the third moving rack 58 to move, thereby controlling the sealing plate 52 to move.

[0068] As a specific example, such as Figure 14 and Figure 15 As shown, the second collection box 51 is symmetrically provided with a third gear 69 that meshes with the first gear 56 and the second gear 57 respectively. The third gear 69 is coaxially provided with a rotating rod 70. The rotating rod 70 is provided with a number of rotating rings 71. The rotating rings 71 are provided with a number of striking parts 72 in a circular array to assist the second collection box 51 in discharging materials.

[0069] Furthermore, when the first gear 56 and the second gear 57 rotate, the third gear 69 drives the rotating rod 70 to rotate. The rotating rod 70 drives the striking element 72 to strike the second collection box 51 through the rotating ring 71, thereby improving the material feeding effect of the second collection box 51.

[0070] Example 4 Based on Example 3, referring to Figure 1 - Figure 16 This is the fourth embodiment of the present invention.

[0071] A method for longitudinal and transverse shearing of galvanized steel strip includes the following steps: S1. The shearing processing table 1 longitudinally shears the galvanized strip steel into several narrow strip steels through the longitudinal shearing structure 2, and then conveys the narrow strip steels to the transverse shearing structure 3 for transverse shearing through the conveying mechanism. S2. During the conveying process, the rotating structure 6 drives the elastic brush roller 13 to rotate through the second synchronous belt structure 15 to clean the zinc dross from the narrow strip steel. The rotating structure 6 drives several conveying rollers 5 to rotate in the same direction. The negative pressure fan 8 and the conveying rollers 5 work together to adsorb the zinc dross on the surface of the narrow strip steel and the roller surface of the conveying rollers 5 into the spiral guide groove 7 for collection through micropores. S3. During the shearing process, when the zinc dross in the first collection box 9 reaches the set amount, the weight sensor triggers an alarm, disassembles and cleans the first collection box 9, and drives the screw transmission structure 20 through the main gear 23 and the lifting gear 22 to make the moving part 21 drive the cleaning scraper 19 to move up and down along the filter plate 18 to clean the impurities intercepted by the filter plate 18. S4. When the screw drive structure 20 is running, the first transmission gear 37 and the first transmission rack 36 drive the second guide slide 35 to move, so that the sealing strip 34 opens the second connecting groove, and controls the cleaning scraper 19 to move to the lower part of the guide box 17. The piston rod 45, the air tank 44 and the nozzle 40 cooperate to spray air at multiple angles to clean the cleaning scraper 19. After cleaning, the cleaning scraper 19 is reset, and the sealing strip 34 re-seals the second connecting groove. S5. The impurities cleaned by the cleaning scraper 19 fall into the first collection box 9 through the second collection box 51. When the first collection box 9 is disassembled for cleaning, the fixing strip 53 drives the first rack 54 and the second rack 55 to cooperate with the control sealing plate 52 to close the second collection box 51. When the first collection box 9 is reset, the third moving rack 58 controls the sealing plate 52 to open the second discharge chute, so that the second collection box 51 and the first collection box 9 are connected to collect impurities.
