Description

Technical Field

[0001] This invention relates to the field of artificial leather cleaning technology, specifically to a cleaning and drying device for artificial leather processing. Background Technology

[0002] Artificial leather is widely used in many fields. The cleanliness of its surface directly affects the quality of the product. The cleaning process is the key to the process. It is necessary to thoroughly remove dirt while protecting the surface of leather materials with different properties. This makes the adaptability and precision of cleaning equipment the core requirements.

[0003] Most current mainstream cleaning equipment uses a fixed pressure cleaning structure, and the brush pressure cannot be dynamically adjusted according to the thickness and surface texture of artificial leather. In actual production, artificial leather has large differences in specifications. Taking lychee-patterned leather as an example, thick leather has a deep texture and hides more dirt, while thin leather has a shallow texture and a fragile surface. The fixed pressure one-size-fits-all mode is difficult to adapt. High pressure can easily damage thin leather, while low pressure cannot clean stubborn stains on thick leather and will also cause defects in subsequent processing. Some companies adapt to different leather materials by manually changing parts or adjusting parameters, but this will interrupt production, reduce efficiency, and the operation precision that relies on experience is low, resulting in unstable product quality.

[0004] In summary, current equipment suffers from poor adaptability, low efficiency, and poor cleaning quality and precision, failing to meet modern processing needs. Therefore, the development of adaptive equipment that can automatically adjust cleaning parameters and has a complete process is an urgent need in the artificial leather processing industry. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning and drying apparatus for artificial leather processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: comprising: an artificial leather cleaning and drying unit, a thickness transmission device, and an adaptive cleaning device. The artificial leather cleaning and drying unit is capable of conveying and drying artificial leather. The thickness transmission device is located near the input end of the artificial leather cleaning and drying unit, and is capable of detecting the thickness of the artificial leather, thereby driving subsequent devices based on the thickness of the artificial leather. The adaptive cleaning device is located at the output end of the thickness transmission device, and is capable of cleaning the artificial leather. The adaptive cleaning device can cooperate with the thickness transmission device, and through the thickness transmission device, the adaptive cleaning device can clean artificial leather of different thicknesses.

[0007] Preferably, for the process of cleaning artificial leather, the artificial leather cleaning and drying unit includes: a support platform, a conveying device, Velcro straps, a drying unit, and spray heads. The support platform is used to support the top connecting parts; the conveying device is set on the top surface of the support platform; there are two Velcro straps, which are symmetrically looped around both ends of the conveyor belt surface of the conveying device; the drying unit is sleeved near the output end of the conveying device, and the bottom end of the drying unit is fixedly connected to the left and right ends of the top surface of the support platform.

[0008] There are two spray heads, which are symmetrically arranged near the input end of the conveying device.

[0009] Preferably, for detecting the thickness of artificial leather, the thickness transmission device includes: a concave support plate, a single-opening rectangular plate, a spring, a bearing seat, a detection roller, a transmission rod, and a first drive assembly. The concave support plate is disposed near the input end of the conveying device and near the front spray head. Two single-opening rectangular plates are symmetrically arranged at the top two ends of the front side of the concave support plate. Two springs are disposed at one end on the top inner wall of each of the two single-opening rectangular plates. Two bearing seats are disposed at the other end of each of the two springs, with the top ends of each bearing seat embedded in the bottom inner cavity of each of the two single-opening rectangular plates, and each bearing seat is capable of limited movement within the inner cavity of the two single-opening rectangular plates. The detection roller is disposed between the bottom rotating ends of the two bearing seats and is capable of limited rotation by the two bearing seats. The transmission rod is disposed at the bottom left side of the outer wall of the left bearing seat. The first drive assembly is disposed at the left end of the transmission rod.

[0010] Preferably, in order to drive the transmission based on the thickness of the artificial leather, the first drive assembly includes: a rack, an L-shaped bearing seat, a rotating column, an eccentric cam, a first gear, a small electric push rod, and a locking block. The rack is located at the left end of the transmission rod; the L-shaped bearing seat is located at the top front end of the left side of the outer wall of the conveying device, and the L-shaped bearing seat extends upward; the rotating column is located inside the rotating end of the L-shaped bearing seat, and the rotating column can be limited to rotate by the L-shaped bearing seat; the eccentric cam is located at the left end of the rotating column; the first gear is located at the right end of the rotating column, and the first gear meshes with the top end of the rack; the small electric push rod is located at the top left end of the concave support plate; the locking block is located at the pushing end of the small electric push rod, and the locking block engages between the teeth of the first gear; when the small electric push rod drives the locking block to retract and move backward, and no longer engages and locks the first gear, the bearing seat moves upward, which can drive the rack to drive the first gear to rotate, thereby the first gear drives the eccentric cam to rotate by the rotating column.

[0011] Preferably, for linking the adaptive cleaning device, the thickness transmission device further includes: a second drive assembly, a limiting ring, an L-shaped support plate, a connecting plate, and a circular pad. The second drive assembly is disposed at the eccentric end of the eccentric cam; the limiting ring is sleeved around the outer wall of the output end of the second drive assembly, and the output end of the second drive assembly can move within the limiting ring; one end of the L-shaped support plate is disposed on the outer wall of the limiting ring, and the other end of the L-shaped support plate is fixedly connected to the left side of the outer wall of the conveying device; the connecting plate is disposed at the output end of the second drive assembly; and the circular pad is disposed on the bottom right end of the connecting plate.

[0012] Preferably, in order to drive the adaptive cleaning device to move downward, the second driving component includes: a first connecting rod, a second connecting rod, and an L-shaped connecting rod. One end of the first connecting rod is disposed at the eccentric end of the eccentric cam, and the other end of the first connecting rod extends upward. One end of the second connecting rod is disposed at the other end of the first connecting rod via a first bearing. One end of the L-shaped connecting rod is disposed at the other end of the second connecting rod via a second bearing, and the L-shaped connecting rod extends rearward. The outer wall of the other end of the L-shaped connecting rod is sleeved within a limiting ring, and the other end of the L-shaped connecting rod can extend to the inner wall of the limiting ring for limited movement. The other end of the L-shaped connecting rod is fixedly connected to the center of the left end of the top surface of the connecting plate. The rotation of the eccentric cam can drive the first connecting rod to drive the second connecting rod to rotate, thereby the second connecting rod can drive the other end of the L-shaped connecting rod to move up and down along the inner wall of the limiting ring for limited movement. Through the mutual cooperation of the first connecting rod, the second connecting rod, and the L-shaped connecting rod, the rotational motion can be converted into a linear driving force for the upper and lower limits of the L-shaped connecting rod, thereby driving the connecting plate and the circular pad to move up and down for limited movement.

[0013] Preferably, to enable the cleaning brush to clean the artificial leather, the adaptive cleaning device includes: a rectangular block, a chamber, a circular groove, a moving groove, a third drive assembly, a moving block, and a cleaning brush. The rectangular block is disposed on the bottom surface of the circular pad. A chamber is formed within the rectangular block. A through circular groove is formed at the center of the top edges of both sides of the outer wall of the rectangular block, and both grooves extend into the chamber. Two symmetrically arranged, through moving grooves are formed at the center of the bottom surface of the rectangular block, and both grooves extend into the chamber. The third drive assembly is disposed at the center of the bottom surface of the inner wall of the chamber. The two moving ends of the third drive component are respectively embedded in the two circular grooves, and the two moving ends of the third drive component extend outwards to both ends. The two moving ends of the third drive component can move downwards within the limits of the two circular grooves. There are two moving blocks, which are respectively disposed on the outer walls of the two moving ends of the third drive component. The two moving blocks are respectively embedded in the center of the two moving grooves, and the two moving blocks extend downwards to the bottom. The cleaning brush is disposed at the bottom of the two moving blocks, and the bottom surface of the cleaning brush is in contact with the conveyor belt of the conveying device.

[0014] Preferably, in order to drive the cleaning brush to clean the artificial leather by moving back and forth, the third drive assembly includes: a second gear, a flat brake motor, a third gear, a transmission block, an incomplete gear, and a threaded rod. The second gear is disposed at the center of the bottom surface of the inner wall of the chamber via a third bearing; the flat brake motor is disposed at the center of the bottom surface of the rectangular block, and the output end of the flat brake motor is connected and fixed to the center of the bottom surface of the second gear; there are two third gears, which are symmetrically disposed at both ends of the center of the bottom surface of the inner wall of the chamber via two fourth bearings, and both third gears mesh with the second gear; there are two transmission blocks, which are disposed at the center of the top surface of the two third gears; there are two incomplete gears, which are disposed at the center of the top surface of the two third gears. The top end of the transmission block; the two ends of the threaded rod are respectively embedded in the two circular grooves, and the two ends of the threaded rod can move within the two circular grooves. The central thread of the threaded rod meshes with the teeth of an incomplete gear, and the central thread of the threaded rod can also mesh with the teeth of another incomplete gear. The outer walls of the two ends of the threaded rod are respectively connected and fixed to the top ends of the two moving blocks. The flat brake motor can drive the second gear to drive the two third gears to rotate, and through the transmission of the two transmission blocks, drive the two incomplete gears to alternately mesh with the threads of the threaded rod, and make the threaded rod reciprocate within the two circular grooves. Thus, the threaded rod drives the cleaning brush to perform a limited reciprocating linear motion through the transmission of the two moving blocks.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The thickness transmission device's detection roller captures the thickness of the artificial leather. The thickness signal is converted into adjustment power through a rack and pinion mechanism. Then, the linkage mechanism of the second drive component smoothly converts the rotational motion into linear driving force, allowing the contact pressure of the cleaning brush to dynamically change with the characteristics of the artificial leather. For thick leather with deep lychee grain and a lot of dirt, it automatically applies pressure to remove stubborn stains, while for thin leather with shallow lychee grain, it automatically reduces pressure to avoid surface damage. This completely abandons the one-size-fits-all approach of traditional equipment and achieves the optimal balance between cleaning precision and material protection.

[0017] 2. The third drive component drives the cleaning brush to reciprocate at high frequency along the width of the artificial leather, and the width of the brush is slightly larger than that of the conveyor belt to ensure no dead corners are covered; the front end sprays cleaning liquid to wet the stains, the middle brushes deeply scrub, and the rear end rinses off the residue with clean water, forming a complete cleaning chain; the drying unit is seamlessly connected after cleaning to avoid mold and wrinkles caused by moisture residue, effectively improving the surface cleanliness and physical properties of the finished artificial leather, and improving the quality of artificial leather processing, cleaning and drying.

[0018] 3. After sensing different thicknesses of artificial leather, the thickness transmission device of the present invention automatically drives the adaptive cleaning device to complete the pressure adjustment. Whether it is thick wear-resistant artificial leather or thin flexible artificial leather, it can stably process cleaning and washing without replacing components or adjusting parameters. It is applicable to artificial leather of different thicknesses and has universality. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-13This invention provides a technical solution for a cleaning and drying device for artificial leather processing, comprising: an artificial leather cleaning and drying unit 1, a thickness transmission device 2, and an adaptive cleaning device 3. The artificial leather cleaning and drying unit 1 can convey and dry the artificial leather, and can also spray and wet and spray clean the artificial leather. The artificial leather cleaning and drying unit 1 provides support for the thickness transmission device 2 and the adaptive cleaning device 3. The thickness transmission device 2 is located near the input end of the artificial leather cleaning and drying unit 1, and can detect the thickness of the artificial leather, thereby transmitting the thickness of the artificial leather to the subsequent devices. Driven by a thickness transmission device 2, the thickness of the artificial leather is adjusted by the thickness of the artificial leather and driven by the adaptive cleaning device 3. The adaptive cleaning device 3 is located at the output end of the thickness transmission device 2. The adaptive cleaning device 3 can clean the artificial leather and can cooperate with the thickness transmission device 2. Through the thickness transmission device 2, the adaptive cleaning device 3 can clean the artificial leather according to the thickness of the artificial leather. The thicker the artificial leather, the deeper the lychee pattern on the cleaning surface and the more dirt is trapped. The thinner the artificial leather, the shallower the lychee pattern on the cleaning surface and the less dirt is trapped. Thus, the adaptive cleaning device 3 adjusts the cleaning pressure according to the thickness of the artificial leather.

[0035] As a preferred option, further, such as Figure 2 As shown, the artificial leather cleaning and drying unit 1 includes: a support platform 11, a conveying device 12, Velcro 13, a drying unit 14, and a spray head 15. The support platform 11 supports the top connecting components and is an important support for the invention, providing mounting points for the top connecting components. The conveying device 12 is located on the top surface of the support platform 11 and is used to transport artificial leather for processing, cleaning, and drying. The conveying device 12 is waterproof. Two Velcro 13s are symmetrically looped around the two ends of the conveyor belt surface of the conveying device 12. Velcro 13 is used to attach the fiber texture of the artificial leather base fabric layer, thereby fixing it to the conveyor belt of the conveying device 12; the drying unit 14 is sleeved near the output end of the conveying device 12, and the bottom end of the drying unit 14 is fixedly connected to the left and right ends of the top surface of the carrying platform 11. The drying unit 14 is used to dry the artificial leather; there are two spray heads 15, which are symmetrically arranged near the input end of the conveying device 12. The front spray head 15 is connected to the external cleaning liquid supply system, and the rear spray head 15 is connected to the external purified water supply system.

[0036] As a preferred option, further, such as Figure 3 , Figure 4 and Figure 5As shown, the thickness transmission device 2 includes: a concave support plate 21, a single-opening rectangular plate 22, a spring 23, a bearing seat 24, a detection roller 25, a transmission rod 26, and a first drive assembly 27. The concave support plate 21 is located near the input end of the conveying device 12 and is close to the front spray head 15. The concave support plate 21 supports two single-opening rectangular plates 22. There are two single-opening rectangular plates 22, which are symmetrically arranged at the top two ends of the front side of the concave support plate 21. The inner cavity of the single-opening rectangular plate 22 is used to limit the deformation of the spring 23 and the bearing seat 24. There are two springs 23, one end of which is respectively located on the top surface of the inner wall of the two single-opening rectangular plates 22. When the two springs are not deformed into a free state, they exert a certain thrust on the two bearing seats 24. This thrust is transmitted through the connecting parts and provides a certain support force to the adaptive cleaning device 3. When the locking block 277 is not locked with the first gear 275, This avoids the adaptive cleaning device 3 from operating or moving the connecting parts by its own gravity; there are two bearing seats 24, which are respectively set at the other end of the two springs 23. The top of the two bearing seats 24 are respectively embedded in the bottom end of the inner cavity of the two single-opening rectangular plates 22, and the two bearing seats 24 can be limited to move within the inner cavity of the two single-opening rectangular plates 22. The two bearing seats 24 are used to support the detection roller 25; the detection roller 25 is set between the bottom rotating ends of the two bearing seats 24. The detection roller 25 can be limited to rotate by the two bearing seats 24. The limited rotation of the detection roller 25 is used to prevent hard friction damage to the cleaning surface when the cleaning surface of the artificial leather comes into contact with the detection roller 25; the transmission rod 26 is set at the bottom left end of the outer wall of the left bearing seat 24. The transmission rod 26 is used for transmission between the bearing seat 24 and the input end of the first drive assembly 27; the first drive assembly 27 is set at the left end of the transmission rod 26.

[0037] As a preferred option, further, such as Figure 4 and Figure 6As shown, the first drive assembly 27 includes: a rack 271, an L-shaped bearing seat 272, a rotating column 273, an eccentric cam 274, a first gear 275, a small electric push rod 276, and a locking block 277. The rack 271 is located at the left end of the transmission rod 26; the L-shaped bearing seat 272 is located at the top front end of the left side of the outer wall of the conveying device 12, and the L-shaped bearing seat 272 extends upwards, serving to support the top connecting assembly; the rotating column 273 is located inside the rotating end of the L-shaped bearing seat 272, and the rotating column 273... The rotating column 273, which is limited to rotation by the L-shaped bearing seat 272, is used for transmission between the eccentric cam 274 and the first gear 275, and also provides support for the eccentric cam 274 and the first gear 275. The eccentric cam 274 is located at the left end of the rotating column 273; the first gear 275 is located at the right end of the rotating column 273, and meshes with the top end of the rack 271; a small electric push rod 276 is located at the left end of the top surface of the concave support plate 21, and the small electric push rod 276 and the locking block 277... The function is that when the invention is not in operation, the locking block 277 can fix and lock the first gear 275, ensuring that the thickness transmission device 2 and the adaptive cleaning device 3 will not be displaced or shaken due to external forces when they are not in operation; another function of the small electric push rod 276 and the locking block 277 is that when the detection roller 25 is no longer in contact with the artificial leather, it can extend the current state of the adaptive cleaning device 3 and continue to clean the artificial leather; the locking block 277 is set at the pushing end of the small electric push rod 276, and the locking block 277 is engaged between the teeth of the first gear 275. The locking block 277 is toothed, which can better fit the first gear 275 and lock it in place. When the small electric push rod 276 drives the locking block 277 to retract and move backward, and no longer locks the first gear 275, the bearing seat 24 moves upward, which can drive the rack 271 to drive the first gear 275 to rotate. Thus, the first gear 275 drives the eccentric cam 274 to rotate in a limited position through the rotating column 273. This first drive assembly 27 is used to transmit the driving power of the artificial leather thickness to the detection roller 25 and transmit it to the second drive assembly 28.

[0038] As a preferred option, further, such as Figure 4 and Figure 8As shown, the thickness transmission device 2 further includes: a second drive assembly 28, a limiting ring 29, an L-shaped support plate 210, a connecting plate 211, and a circular pad 212. The second drive assembly 28 is disposed at the eccentric end of the eccentric cam 274; the limiting ring 29 is sleeved around the outer wall of the output end of the second drive assembly 28, and the output end of the second drive assembly 28 can move within the limiting ring 29. The limiting ring 29 is used to limit the up-and-down movement of the bottom end of the L-shaped connecting rod 283; one end of the L-shaped support plate 210 is disposed at the limiting ring 212. The outer wall of ring 29, the other end of L-shaped support plate 210 is fixedly connected to the left side of outer wall of conveying device 12, and L-shaped support plate 210 is used to support limiting ring 29; connecting plate 211 is set at the output end of second drive assembly 28, connecting plate 211 is used to support and extend circular pad 212 located at the center of conveyor belt of conveying device 12; circular pad 212 is set on the bottom right end of connecting plate 211, circular pad 212 is used to connect and fix connecting plate 211 to the center of top surface of rectangular block 31.

[0039] As a preferred option, further, such as Figure 4 and Figure 7 As shown, the second drive assembly 28 includes: a first connecting rod 281, a second connecting rod 282, and an L-shaped connecting rod 283. One end of the first connecting rod 281 is disposed at the eccentric end of the eccentric cam 274, and the other end of the first connecting rod 281 extends upward. One end of the second connecting rod 282 is disposed at the other end of the first connecting rod 281 via a first bearing, and the second connecting rod 282 can rotate via the first bearing. One end of the L-shaped connecting rod 283 is disposed at the other end of the second connecting rod 282 via a second bearing, and the L-shaped connecting rod 283 can rotate via the second bearing. The L-shaped connecting rod 283 extends backward, and the outer wall of the other end of the L-shaped connecting rod 283 is sleeved within a limiting ring 29. The other end of the L-shaped connecting rod 283 can extend to the inner wall of the limiting ring 29 for limited movement. The other end of the L-shaped connecting rod 283 is aligned with the center of the left end of the top surface of the connecting plate 211. The connection is fixed; the rotation of the eccentric cam 274 can drive the first connecting rod 281 to drive the second connecting rod 282 to rotate, so that the second connecting rod 282 can drive the other end of the L-shaped connecting rod 283 to move up and down along the inner wall of the limiting ring 29. Through the cooperation of the first connecting rod 281, the second connecting rod 282 and the L-shaped connecting rod 283, the rotational motion can be converted into a linear driving force for the upper and lower limits of the L-shaped connecting rod 283, thereby driving the connecting plate 211 and the circular pad 212 to move up and down. This second driving assembly 28 can drive the L-shaped connecting rod 283 to move in a buffered manner through the eccentric cam 274, thereby driving the cleaning brush 37 to move in a buffered manner, preventing the cleaning brush 37 from moving directly downward through the drive of the detection roller 25, which would cause the brush head of the cleaning brush 37 to have a hard impact with the conveyor belt of the conveying device 12 and be damaged.

[0040] As a preferred option, further, such as Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the adaptive cleaning device 3 includes: a rectangular block 31, a chamber 32, a circular groove 33, a moving groove 34, a third drive assembly 35, a moving block 36, and a cleaning brush 37. The rectangular block 31 is disposed on the bottom surface of the circular pad 212. The chamber 32 is formed inside the rectangular block 31. A through circular groove 33 is formed at the center of the top of both sides of the outer wall of the rectangular block 31, and both circular grooves 33 extend into the chamber 32. Two through symmetrical moving grooves 34 are formed at the center of the bottom surface of the rectangular block 31, and both moving grooves 34 extend into the chamber 32. The rectangular block 31 provides installation space for the third drive assembly 35. The third drive assembly 35 is disposed at the center of the bottom surface of the inner wall of the chamber 32. The two moving ends of the third drive assembly 35 are respectively embedded in the two circular grooves 33. The two moving ends of component 35 extend outwards to both ends respectively. The two moving ends of the third drive component 35 can move downwards to be limited by the two circular grooves 33 respectively. There are two moving blocks 36, which are respectively set on the outer wall of the two moving ends of the third drive component 35. The two moving blocks 36 are respectively embedded in the center of the two moving grooves 34, and the two moving blocks 36 extend downwards to the bottom. The two moving blocks 36 are not only used to support the cleaning brush 37, but also to prevent and limit the rotation of the threaded rod 356 during movement. The cleaning brush 37 is set at the bottom of the two moving blocks 36, and the bottom surface of the cleaning brush 37 is in contact with the conveyor belt of the conveying device 12. The cleaning brush 37 is longer than the lateral width of the conveyor belt of the conveying device 12 to ensure full contact with the cleaning surface of the artificial leather.

[0041] As a preferred option, further, such as Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, the third drive assembly 35 includes: a second gear 351, a flat brake motor 352, a third gear 353, a transmission block 354, an incomplete gear 355, and a threaded rod 356. The second gear 351 is mounted on the center of the bottom surface of the inner wall of the chamber 32 via a third bearing, and the second gear 351 can rotate via the third bearing. The flat brake motor 352 is mounted on the center of the bottom surface of the rectangular block 31, and the output end of the flat brake motor 352 is connected and fixed to the center of the bottom surface of the second gear 351. The flat brake motor 352 is relatively large and can ensure that it can drive the cleaning brush 37 to clean the artificial leather. The small height of the electric motor 352 makes it suitable for applications with a compact structural layout. The flat brake motor 352 has a certain self-locking capability to prevent displacement or loosening of its output end connection components due to external forces. There are two third gears 353, which are symmetrically arranged at both ends of the bottom surface of the inner wall of the chamber 32 via two fourth bearings. The two third gears 353 can rotate through the two fourth bearings, and both third gears 353 mesh with the second gear 351. There are two transmission blocks 354, which are respectively arranged at the center of the top surface of the two third gears 353. The two transmission blocks 354 are the two third gears 351. The transmission between gear 353 and two incomplete gears 355; there are two incomplete gears 355, which are respectively set at the top of two transmission blocks 354; the two ends of the threaded rod 356 are respectively embedded in two circular grooves 33, and the two ends of the threaded rod 356 can be limited to move within the two circular grooves 33; the center thread of the threaded rod 356 meshes with the teeth of one incomplete gear 355, and the center thread of the threaded rod 356 can also mesh with the teeth of the other incomplete gear 355; the outer walls of the two ends of the threaded rod 356 are respectively connected and fixed to the top of two moving blocks 36; flat brake motor 3 52 can drive the second gear 351 to drive the two third gears 353 to rotate, and through the transmission of the two transmission blocks 354, drive the two incomplete gears 355 to alternately mesh with the threads of the threaded rod 356, and make the threaded rod 356 reciprocate within the two circular grooves 33. Thus, the threaded rod 356 is driven by the transmission of the two moving blocks 36 to make the cleaning brush 37 perform a limited reciprocating linear motion. This third drive assembly 35 can drive the cleaning brush 37 to perform a limited reciprocating linear motion to fully cover the artificial leather cleaning surface, deeply remove dirt from the texture gaps, and improve the uniformity and thoroughness of cleaning.

[0042] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, and the specific work is as follows:

[0043] When started, the small electric push rod 276 drives the locking block 277 to retract and no longer locks and fixes the first gear 275. The staff places the artificial leather on the conveying end in front of the conveying device 12, and the artificial leather base fabric layer on both sides is fixed by the fiber texture of the artificial leather base fabric layer and the two Velcro 13.

[0044] The artificial leather is conveyed by the conveying device 12 and sprayed and cleaned by the front spray head 15.

[0045] The artificial leather is conveyed by the conveying device 12, so that the artificial leather lifts the detection roller 25 by its own thickness. The detection roller 25 is used as the power source to drive the first drive component 27 and the second drive component 28 to transmit power to the adaptive cleaning device 3. The thicker the artificial leather and the deeper the lychee pattern, the more dirt is hidden. The thicker the artificial leather lifts the detection roller 25 higher, and the greater the contact pressure between the brush head of the cleaning brush 37 and the cleaning surface of the artificial leather. Similarly, the thinner the artificial leather and the shallower the lychee pattern, the less dirt is hidden. The contact pressure of the brush head of the cleaning brush 37 is smaller. Thus, the cleaning brush 37 adaptively adjusts the contact pressure of the brush head according to the thickness of different artificial leathers, so it is suitable for cleaning artificial leather of different thicknesses, and improves the quality and precision of cleaning artificial leather, and has versatility.

[0046] When the cleaning brush 37 adaptively adjusts to contact the artificial leather cleaning surface, the small electric push rod 276 drives the locking block 277 to lock and fix the first gear 275. This prevents the connecting parts of the adaptive cleaning device 3 from shaking or shifting during operation. Then, the third drive component 35 drives the cleaning brush 37 to reciprocate and brush the artificial leather cleaning surface. At the same time, the locking block 277 locks and fixes the first gear 275 to prevent the artificial leather end from not being cleaned when the detection roller 25 automatically resets after passing through the detection roller 25. Therefore, the locking block 277 locks and fixes the first gear 275 for a certain period of time, so that the cleaning brush 37 can maintain the current state and continue cleaning.

[0047] After the artificial leather is cleaned by the cleaning brush 37, it is rinsed by the clean water sprayed by the spray head 15 at the rear end, and the processing and cleaning of the artificial leather is completed. Then, it is driven by the conveyor device 12 to the drying unit 14 for drying, and the cleaning and drying of the artificial leather is completed.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
