They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-10 As shown, a leather processing fabric cleaning device includes a housing 1. Support piles 2 are provided at the lower ends of the left and right sides of the housing 1. Two guide rollers 3 are horizontally rotatably installed on the inner walls of the front and rear sides of the housing 1. The two guide rollers 3 are used to guide and transfer the fabric inside the housing 1. The inner walls of the left and right sides of the housing 1 are provided with staggered guide openings 4. The staggered guide openings 4 facilitate the connection of the fabric with the two guide rollers 3. Limiting rollers 10 are fixedly installed on the top and bottom surfaces of the two guide openings 4. The two limiting rollers 10 inside the guide openings 4 can limit the fabric passing through the guide openings 4 to prevent wrinkles from forming when the fabric is cleaned. The fabric passing through the guide openings 4 is in contact with the two limiting rollers 10. An inspection door 11 is opened on the front side wall of the housing 1. The lower ends of the first fixing pile 6 and the second fixing pile 7 on the front side are respectively fixedly connected to the upper ends of the two support seats 5. The lower ends of the first fixing pile 6 and the second fixing pile 7 on the rear side are slidably connected to the upper ends of the two support seats 5.

[0021] Support seats 5 are fixedly connected to the opposite side walls of the two support piles 2 near the upper end. The upper end of the left support seat 5 away from the box body 1 is provided with two first fixed piles 6, and the upper end of the right support seat 5 away from the box body 1 is provided with two second fixed piles 7. The upper front side of the two support seats 5 is fixedly installed with a reduction motor 12. The drive shaft of the two reduction motors 12 is coaxially fixedly connected with a drive wheel 13. The reduction motor 12 is used to drive the drive wheel 13 to rotate. The two drive wheels 13 are respectively connected to the unwinding roller 8 and the winding roller 9.

[0022] Both support bases 5 have fixed grooves 14 fixedly connected to their upper rear ends away from the geared motor 12. A servo motor 15 is fixedly installed on the upper right side of the left support base 5 near the fixed groove 14. Lead screws 16 are fixedly connected to the drive shafts of the servo motors 15. The servo motors 15 drive the lead screws 16 on the left side to rotate. The two lead screws 16 are horizontally rotating and pass through the inner walls of the left and right sides of the two fixed grooves 14. A transmission wheel 17 is coaxially fixedly connected to the end of each lead screw 16 away from the servo motor 15. The two transmission wheels 17 are connected by a belt drive. The rotation of the left lead screw 16 drives the coaxially connected transmission wheel 17. The rotation causes the two transmission wheels 17 to drive the right lead screw 16 to rotate simultaneously in the same direction. One end of each lead screw 16 located in the fixed groove 14 is threaded with a displacement block 18. The side wall of the displacement block 18 slides against the inner wall of the fixed groove 14. The upper ends of the two displacement blocks 18 are fixedly connected to the lower ends of the first fixed post 6 and the second fixed post 7 on the rear side, respectively. The rotation of the two lead screws 16 drives the threaded displacement blocks 18 to move horizontally along the fixed groove 14, and the displacement blocks 18 drive the first fixed post 6 on the rear side to move horizontally to the first fixed post 6 on the front side, and the second fixed post 7 on the rear side to move horizontally to the second fixed post 7 on the front side.

[0023] A unwinding roller 8 is provided between two first fixed posts 6, and a winding roller 9 is provided between two second fixed posts 7. A rotating rod 19 is horizontally rotatably mounted on the opposite sidewalls near the upper ends of both the first fixed posts 6 and the two second fixed posts 7. Driven wheels 20 are coaxially fixedly connected to the two front rotating rods 19. Two driving wheels 13 are connected to the two driven wheels 20 via belt drive. The rotation of the two driving wheels 13 drives the two belt-driven driven wheels 20 to rotate, causing the two driven wheels 20 to drive the two coaxially connected front rotating rods 19 to rotate. This causes the two rotating rods 19 on the same side to simultaneously rotate the locked unwinding roller 8 and the winding roller 9, allowing the unwinding roller 8 to release the fabric and guide it to the winding roller 9 for winding, in conjunction with the guide opening 4 and the limiting roller 10. As the fabric unfolds along the guide opening 4 and the limiting roller 10, a dirt-removing mechanism cleans the fabric. Positioning blocks 21 are fixedly connected to the opposite sidewalls of the two rotating rods 19 on the same side. Hexagonal slots 22 are provided on the opposite sidewalls of the two positioning blocks 21 on one side. Roller shafts 23 are provided at both ends of the unwinding roller 8 and the winding roller 9. The two roller shafts 23 on the same side are respectively positioned opposite the two positioning blocks 21 on the same side. Hexagonal protrusions 24 are provided at the ends of the two roller shafts 23 on the same side that are facing the positioning blocks 21. The two hexagonal protrusions 24 on the same side are respectively inserted into the two hexagonal slots 22 on the same side. The rotation of the two lead screws 16 drives the threaded displacement block 18 to move along the fixed groove. 14. Move horizontally, and the displacement block 18 drives the rear first fixed post 6 to move horizontally to the front first fixed post 6, and the rear second fixed post 7 to move horizontally to the front second fixed post 7, until the hexagonal protrusions 24 on the roller shafts 23 at both ends of the unwinding roller 8 and the winding roller 9 can be inserted into the hexagonal slots 22 on the two positioning blocks 21 on the same side, effectively locking and positioning the unwinding roller 8 between the two first fixed posts 6, and locking and positioning the winding roller 9 between the two second fixed posts 7.

[0024] The bottom of the box 1 is equipped with a material collection assembly, which includes an open-top recycling trough 25 placed on the bottom of the box 1. The open-top recycling trough 25 is filled with clean water and is used to collect waste. Inclined baffles 26 are fixedly connected to the inner walls of the left and right sides of the box 1 near the open-top recycling trough 25. The inclined lower ends of the two inclined baffles 26 face into the open-top recycling trough 25. The side walls of the two inclined baffles 26 are seamlessly connected to the inner wall of the box 1. The two inclined baffles 26 can guide the scraped waste into the open-top recycling trough 25 filled with clean water.

[0025] The housing 1 is equipped with a decontamination mechanism, which includes a support plate 27 fixedly connected to the inner rear wall of the housing 1. The support plate 27 is positioned near the upper end of the uncovered recycling trough 25. Hydraulic cylinders 28 are fixedly installed on the upper end of the support plate 27 and the top surface of the housing 1. Connecting plates 29 are fixedly connected to the opposite side walls of the piston rods of the two hydraulic cylinders 28. The hydraulic cylinders 28, in conjunction with the connecting plates 29, drive several conical scrapers 34 to contact the stretched and guided fabric. This ensures that several springs 32 within the strip groove 31, in conjunction with the movable plate 33, drive several conical scrapers 34 on both sides to always contact and scrape the upper and lower ends of the fabric, effectively removing dirt from the upper and lower ends of the fabric. Several strip blocks 30 are fixedly connected to the opposite side walls of the two connecting plates 29. The strip blocks 30 are arranged in pairs facing each other. Each of the opposite sidewalls of the strip blocks 30 is provided with a strip groove 31. Each of the opposite inner walls of the strip grooves 31 is fixedly connected with a spring 32. Each of the springs 32 on the same side is fixedly connected with a movable plate 33 at the end away from the inner wall of the strip groove 31. The movable plate 33 slides and abuts against the inner wall of the strip groove 31. When the conical scraper 34 comes into contact with the unfolded fabric, it drives the movable plate 33 to compress the springs 32 in the strip groove 31, so that the springs 32 drive the conical scraper 34 to always be in contact with the end face of the fabric, effectively cleaning the dirt attached to the fabric. Each of the movable plates 33 is fixedly connected with a conical scraper 34 at the sidewall away from the springs 32, and each of the conical scrapers 34 on the same side abuts against the fabric.

[0026] A blower mechanism is provided on the top surface of the housing 1. The blower mechanism includes blowers 35 fixedly installed on the top surfaces of the left and right sides of the housing 1. Two drivers 36 are fixedly installed on the upper end of the housing 1. The two drivers 36 are electrically connected to the two blowers 35 respectively. When the two drivers 36 are started, they drive the two blowers 35 to operate, so that the two blowers 35, together with the two inclined baffles 26, blow the removed dirt into the uncovered recycling tank 25 filled with clean water, which facilitates timely cleaning of the surface dirt of the leather fabric. Two annular covers 37 are fixedly connected to the top surface of the housing 1. The two annular covers 37 are respectively fitted onto the two blowers 35. Dustproof nets 38 are fixedly installed at the lower end of the two annular covers 37. The dustproof nets 38 can prevent dirt from adhering to the inside of the blowers 35.

[0027] In use, the unwinding roller 8 is first placed between two first fixed posts 6, and then the take-up roller 9 is placed between two second fixed posts 7. The servo motor 15 on the left support 5 is started to drive the lead screw 16 in the fixed groove 14 to rotate, so that the lead screw 16 drives the coaxially connected transmission wheel 17 to rotate, and the two transmission wheels 17 drive the lead screw 16 on the right side to rotate simultaneously in the same direction. This rotation of the two lead screws 16 causes the threaded displacement block 18 to move horizontally along the fixed groove 14, and the displacement block 18 drives the rear first fixed post 6 to move horizontally towards the front first fixed post 6. The rear second fixed post 7 is moved horizontally to the front second fixed post 7 until the hexagonal protrusions 24 on the roller shafts 23 at both ends of the unwinding roller 8 and the take-up roller 9 can be inserted into the hexagonal slots 22 on the two positioning blocks 21 on the same side, effectively locking and positioning the unwinding roller 8 between the two first fixed posts 6 and the take-up roller 9 between the two second fixed posts 7. When replacing, simply start the servo motor 15 to drive the two first fixed posts 6 or the two second fixed posts 7 to increase the relative distance until the roller shafts 23 of the unwinding roller 8 and the take-up roller 9 can be separated from the hexagonal slots 22. For easy replacement of the unwinding roller 8 and the take-up roller 9, after opening the inspection door 11, the fabric on the unwinding roller 8 is passed through the left guide opening 4 and laid flat in an S-shape along the two guide rollers 3. The fabric is then passed through the right guide opening 4 and connected to the take-up roller 9. After closing the inspection door 11, the reduction motor 12 is started to drive the drive wheel 13 to rotate, which in turn drives the driven wheel 20 connected by the belt drive to rotate. The driven wheel 20 drives the coaxially connected front rotating rod 19 to rotate, which in turn drives the two rotating rods 19 on the same side to rotate the unwinding roller 8 and the take-up roller 9 that are locked in place. This activates the top surface of the housing 1 and the support. The hydraulic cylinder 28 at the upper end of plate 27 causes two hydraulic cylinders 28 to work with connecting plate 29 to drive several conical scrapers 34 to contact the stretching guide fabric. This causes several springs 32 in strip groove 31 to work with movable plate 33 to drive several conical scrapers 34 on the upper and lower sides to always contact the upper and lower ends of the fabric for cleaning, effectively removing dirt from the upper and lower ends of the fabric. The two drivers 36 are started to drive two blowers 35 to run, so that the two blowers 35 work with two inclined baffles 26 to blow the removed dirt into the uncovered recycling tank 25 filled with clean water, which facilitates timely cleaning of the surface dirt of the leather fabric.
