[0002] In the process of processing artificial leather, in order to improve the smoothness and gloss of the leather surface and ensure the aesthetics of the finished product, a polishing machine is needed to polish the surface of the artificial leather.

[0003] Prior art 1 (Chinese patent application number: 202020998998.X, application date: 2020-06-03) discloses a leather polishing machine, including a workbench; a transmission belt disposed on the upper surface of the workbench; a support frame disposed on the side wall of the workbench; a polishing mechanism fixedly connected to the support frame, the polishing mechanism including several mounting tubes rotatably connected to the support frame, a sealing plug disposed at the upper port of the mounting tube, a polishing disc with an internal cavity disposed at the lower end of the mounting tube, the lower end of the mounting tube penetrating through the upper end of the polishing disc, several feeding holes penetrating through the bottom wall of the polishing disc, and a polishing brush disposed at the lower end of the polishing disc; a control mechanism for sealing or opening the lower port of the mounting tube; a first drive mechanism for driving the mounting tube to rotate; and a second drive mechanism for driving the support frame to move vertically. By setting mounting tubes connected to the polishing disc and polishing brush, polishing agent is stored in the mounting tubes, allowing the polishing agent to automatically penetrate into the polishing brush, saving labor and allowing the polishing agent to contact the leather more evenly, improving polishing efficiency and effect.

[0004] Prior art 2 (Chinese patent application number: 202320608182.5, filed on 2023-03-18) discloses a leather polishing machine, belonging to the technical field of leather polishing. Its key technical feature is that it includes a polishing table, which comprises: a polishing device; a driving device for driving the polishing device to move, the driving device being positioned between the polishing device and the polishing table; a clamping device positioned on the polishing table, the clamping device including a clamping seat; and a dust collection device installed and connected to the polishing table, the dust collection device including a dust suction port; wherein the dust suction port is positioned on the clamping seat. This application provides a leather polishing machine that improves the efficiency of polishing table debris collection.

[0005] Prior art 3 (Chinese patent application number: 201710759133.0, application date: 2017-08-30) discloses a polishing device for leather. This invention has a reasonable and simple structure, low production cost, and convenient installation. The first polishing wheel can be height adjusted to suit leather of different thicknesses and prevent wrinkles. In addition, a flattening wheel is provided to flatten the leather and further prevent wrinkles. Several second polishing wheels polish the leather. In order to prevent the polishing wheel from getting too hot during operation, a polishing liquid chamber is provided to cool the polishing wheel. In order to solve the problem of excessive dust during processing, a fan is started to extract the dust, and the dust enters the water chamber for filtration and is then discharged.

[0006] Existing polishing devices mostly use continuous conveying or manual locking when polishing leather, which cannot effectively and conveniently limit the leather. This makes the leather prone to wrinkles during the polishing process, thus affecting the overall polishing. At the same time, it is inconvenient to automatically spray polishing agent during the polishing process, which has certain defects in use. Summary of the Invention

[0007] The purpose of this invention is to provide a polishing machine for processing artificial leather, in order to solve the problems mentioned in the background art. Most polishing devices on the market currently use continuous conveying or manual locking when polishing leather, which cannot effectively and conveniently limit the leather, causing wrinkles to easily occur during the polishing process, thus affecting the overall polishing. At the same time, it is inconvenient to automatically spray polishing agent during the polishing process.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a polishing machine for processing artificial leather, comprising a stable cabinet, an arched frame fixedly installed at the upper end of the cabinet, a top plate fixedly installed above the arched frame, an electric push rod fixedly installed at the top of the top plate, and a lifting plate fixedly connected to the output end of the electric push rod through the top plate; a motor fixedly installed on the outside of the lifting plate, and a threaded rod fixedly connected to the output end of the motor.

[0009] It also includes: guide rods, which are fixedly installed on the lower surface of the top plate;

[0010] An adjustment assembly is mounted on a threaded rod, and a polishing roller is also mounted on the adjustment assembly. The polishing roller polishes the leather surface by being driven by the adjustment assembly.

[0011] The push block is elastically and telescopically installed on the outside of the lifting platform;

[0012] Two sets of clamping components are symmetrically installed on the front and rear sides of the arched frame. A driving mechanism is provided between the clamping components and the push block to realize the automatic clamping function of the clamping components.

[0013] The spray assembly, located on the outside of the arched frame, sprays polishing agent onto the leather surface through the drive of the clamping assembly.

[0014] Preferably, the guide rod is perpendicular to the top plate, and the guide rod passes through the lifting plate and forms a lifting structure with the lifting plate. During the downward movement of the lifting plate, the polishing roller is driven to adhere to the surface of the artificial leather.

[0015] By adopting the above technical solution, the position and height of the polishing roller can be adjusted during the upgrading and adjustment process of the lifting plate, which facilitates the placement and polishing of artificial leather.

[0016] Preferably, a lifting rod is fixedly connected to the upper end of the push block, and the lifting rod passes through the lifting plate. A second spring is connected between the lifting plate and the push block. The driving mechanism includes a linkage rod disposed below the push block, and a roller is rotatably mounted on the top of the linkage rod. The clamping assembly includes tension seats symmetrically mounted on both sides of the arch frame. The linkage rod and the tension seats constitute a lifting structure. During the downward movement of the inclined surface of the push block, it is in contact with the roller on the top of the linkage rod.

[0017] By adopting the above technical solution, during the downward movement of the lifting plate, the lifting plate will drive the push block to move downward through the second spring, so that the inclined surface of the push block abuts against the roller, thereby causing the linkage rod to move downward on the tension seat.

[0018] Preferably, the tension seat and the arched frame are elastically slidably connected, and a clamp is elastically rotatably mounted on the tension seat. A gear is fixedly mounted on the shaft of the clamp, and tooth blocks are evenly arranged on the outer side of the lower end of the linkage rod. When the linkage rod moves down, the tooth blocks on its outer side mesh with the gear to drive the clamp to rotate elastically.

[0019] By adopting the above technical solution, the linkage rod can drive the clamp to rotate elastically during the downward movement, which facilitates the subsequent automatic clamping and fixing of the artificial leather.

[0020] Preferably, the clamping assembly further includes a fixing post fixedly installed on the stretching seat, and the clamp is arranged in an arc shape, and the clamp cooperates with the fixing post to clamp and fix the edge of the artificial leather during the rotation of the clamp.

[0021] By adopting the above technical solution, the edge position of the artificial leather is automatically clamped and fixed in conjunction with the fixing column during the rotation of the clamp, thus ensuring the stability of the artificial leather polishing process.

[0022] Preferably, during the continuous downward movement of the push block, the tension seat and clamping plate that have completed clamping are pushed to slide, and the artificial leather is stretched and flattened during the elastic sliding of the two tension seats.

[0023] By adopting the above technical solution, after the clamping plate completes the clamping of the artificial leather, the lifting plate continues to move downward, which will cause the push block to push the linkage rod and the stretching seat to slide elastically, thereby stretching and flattening the clamped artificial leather.

[0024] Preferably, the adjustment assembly includes a movable seat threadedly connected to a threaded rod, and an adjustment plate is connected below the movable seat. The lower end of the adjustment plate is symmetrically and elastically rotatably connected to a movable frame, while the lower end of the movable frame is fixedly connected to a polishing roller.

[0025] By adopting the above technical solution, when the threaded rod drives the movable seat to move back and forth, it can drive the polishing roller to slide on the surface of the artificial leather, thereby realizing the automatic polishing of the artificial leather surface.

[0026] Preferably, two telescopic rods are symmetrically and vertically installed on the movable seat, and the lower end of the telescopic rod is fixedly connected to the upper surface of the adjusting plate. A first spring is connected between the upper end of the telescopic rod and the movable seat. Meanwhile, inverted triangular abutment blocks are uniformly fixedly installed on the lower surface of the lifting plate. As the telescopic rod moves with the movable seat, its upper end slides against the inclined surface of the abutment block.

[0027] By adopting the above technical solution, when the movable seat moves back and forth, the telescopic rod will elastically rise and fall under the contact of the contact block, so that the adjusting plate will rise and fall synchronously. At this time, the movable frame will elastically rotate, further promoting the polishing effect of the polishing roller on the artificial leather.

[0028] Preferably, the spray assembly includes a clamping plate fixedly installed below the stretching seat and a fixing plate fixedly installed on the upper surface of the cabinet, and a liquid bladder is fixedly bonded between the clamping plate and the fixing plate. A liquid storage tank is fixedly installed between the cabinet and the arched frame, and a spray pipe is fixedly installed above the stretching seat, with the spray nozzles of the spray pipe facing the artificial leather. An outlet pipe and an inlet pipe are respectively connected between the liquid bladder, the spray pipe, and the liquid storage tank, and both the outlet pipe and the inlet pipe are equipped with a one-way valve structure.

[0029] By adopting the above technical solution, when the stretching seat moves to stretch the artificial leather, the liquid bladder can be squeezed by the clamping plate, so that the liquid bladder can transport the polishing machine sucked in by its inner side to the spray pipe. When the polishing is completed, during the resetting process of the stretching seat, the liquid bladder will be driven to extract the polishing machine from the liquid storage tank, which is convenient for subsequent reuse.

[0030] Preferably, the spray pipe has spray holes evenly distributed on it, and the openings of the spray holes face the surface of the artificial leather.

[0031] By adopting the above technical solution, the equipment can automatically and evenly spray polishing agent onto the surface of the artificial leather while fixing and leveling it.

[0032] Compared with the prior art, the beneficial effects of the present invention are: the polishing machine for artificial leather processing can automatically clamp and stretch and level artificial leather, and can automatically and evenly spray polishing agent during the leveling process. At the same time, the multi-directional polishing method improves the polishing effect. The specific details are as follows.

[0033] 1. Equipped with a lifting plate, push block, linkage rod, fixed column, and clamping plate, the end of the artificial leather to be polished is placed on the stretching seat. The lifting plate is controlled to move down, which can drive the linkage rod to move down through the push block. The toothed block at the lower end of the linkage rod drives the clamping plate to rotate through meshing, so that the clamping plate clamps the edge of the artificial leather against the outside of the fixed column, thereby realizing automatic clamping and fixing of the artificial leather.

[0034] 2. It is equipped with a push block, a stretching seat and a linkage rod. After the clamping plate finishes clamping the artificial leather, the lifting plate continues to move down. At this time, the top roller of the linkage rod will roll along the inclined surface of the push block, thereby driving the stretching seat to slide elastically on the arch frame through the linkage rod. At this time, the two stretching seats can stretch the artificial leather synchronously, realize the automatic leveling of the artificial leather, and ensure the subsequent polishing effect.

[0035] 3. Equipped with a movable seat, an adjusting plate, and a polishing roller, the movable seat can be moved back and forth by starting the motor via the threaded rod, allowing the polishing roller to automatically polish the surface of the artificial leather. At the same time, the adjusting plate will be adjusted up and down by the contact block, causing the movable frame below the adjusting plate to rotate back and forth elastically, ensuring that the polishing roller can perform multi-directional friction polishing on the surface of the artificial leather, effectively improving the polishing efficiency.

[0036] 4. Equipped with a liquid bladder and a spray pipe, as the stretching seat moves, the stretching seat can squeeze the liquid bladder through the clamp, so that the polishing agent in the liquid bladder can be transported through the pipe to the spray pipe, and then sprayed onto the surface of the artificial leather through the spray holes on the spray pipe. When the stretching seat returns to its original position, it can stretch the liquid bladder to draw polishing agent from the liquid storage tank again, which is convenient for subsequent use.

[0047] Example 1: Please refer to Figures 1-7 and Figure 9 As shown, existing polishing machines for artificial leather processing are inconvenient for automatically clamping and leveling artificial leather, resulting in low polishing efficiency. Furthermore, they are inconvenient for automatically spraying polishing agent during the fixing process. In order to solve this technical problem, this embodiment discloses the following technical content.

[0048] A polishing machine for processing artificial leather includes a stable cabinet 1, an arched frame 2 fixedly installed on the upper end of the cabinet 1, a top plate 3 fixedly installed above the arched frame 2, an electric push rod 4 fixedly installed on the top of the top plate 3, and a lifting plate 5 fixedly connected to the output end of the electric push rod 4 through the top plate 3. Meanwhile, a motor 7 is fixedly installed on the outside of the lifting plate 5, and a threaded rod 8 is fixedly connected to the output end of the motor 7.

[0049] It also includes: a guide rod 6, fixedly installed on the lower surface of the top plate 3; a push block 16, elastically telescopically installed on the outside of the lifting plate 5; two sets of clamping components, symmetrically installed on the front and rear sides of the arch frame 2, with a drive mechanism between the clamping components and the push block 16 to realize the automatic clamping function of the clamping components; and a spraying component, located on the outside of the arch frame 2, which sprays polishing agent onto the leather surface through the drive of the clamping components.

[0050] The guide rod 6 is perpendicular to the top plate 3, and the guide rod 6 passes through the lifting plate 5 and forms a lifting structure with the lifting plate 5. During the downward movement of the lifting plate 5, the polishing roller 14 is driven to adhere to the surface of the artificial leather.

[0051] A lifting rod 15 is fixedly connected to the upper end of the push block 16, and the lifting rod 15 passes through the lifting plate 5. A second spring 17 is connected between the lifting plate 5 and the push block 16. The driving mechanism includes a linkage rod 19 located below the push block 16, and a roller is rotatably mounted on the top of the linkage rod 19. The clamping assembly includes tension seats 18 symmetrically mounted on both sides of the arch frame 2. The linkage rod 19 and the tension seats 18 form a lifting structure. During the downward movement of the inclined surface of the push block 16, it is in contact with the roller on the top of the linkage rod 19.

[0052] The tension seat 18 and the arched frame 2 are elastically slidably connected, and the clamp 21 is elastically rotatably mounted on the tension seat 18. The shaft of the clamp 21 is fixedly mounted with a gear 22. Meanwhile, tooth blocks are evenly arranged on the outer side of the lower end of the linkage rod 19. When the linkage rod 19 moves down, the tooth blocks on its outer side mesh with the gear 22 to drive the clamp 21 to rotate elastically.

[0053] The clamping assembly also includes a fixing post 20 fixedly installed on the stretching seat 18, and the clamp 21 is arranged in an arc shape. During the rotation of the clamp 21, it cooperates with the fixing post 20 to clamp and fix the edge of the artificial leather.

[0054] As the pusher block 16 continues to move downward, it pushes the tension seat 18 and clamping plate 23, which have completed clamping, to slide. During the elastic sliding process of the two tension seats 18, the artificial leather is stretched and flattened.

[0055] The spray assembly includes a clamping plate 23 fixedly installed below the stretching seat 18 and a fixing plate 24 fixedly installed on the upper surface of the cabinet 1. A liquid bladder 25 is fixedly bonded between the clamping plate 23 and the fixing plate 24. A liquid storage tank 27 is fixedly installed between the cabinet 1 and the arched frame 2. A spray pipe 26 is fixedly installed above the stretching seat 18, and the spray nozzles of the spray pipe 26 face the artificial leather. An outlet pipe and an inlet pipe are respectively connected between the liquid bladder 25, the spray pipe 26, and the liquid storage tank 27. Both the outlet pipe and the inlet pipe are equipped with a one-way valve structure.

[0056] Spray holes are evenly distributed on the spray pipe 26, and the openings of the spray holes face the surface of the artificial leather.

[0057] By adopting the above technical solution, when artificial leather needs to be polished, both ends of the artificial leather are placed above the stretching seat 18, so that the ends of the artificial leather are located between the fixing post 20 and the clamping plate 23. Then, the electric push rod 4 is controlled to push the lifting plate 5, so that the lifting plate 5 moves down along the guide rod 6. At this time, the lifting plate 5 will drive the push block 16 to move down synchronously through the second spring 17. At this time, the push block 16 will contact and push the linkage rod 19 to move down synchronously and elastically, so that the tooth block and gear 22 at the lower end of the linkage rod 19 mesh and connect, thereby driving the clamping plate 23 to rotate elastically. The water-piercing clamping plate 23 will fold and bend the edge of the artificial leather, thereby cooperating with the fixing post 20 to automatically clamp and fix the artificial leather. After the artificial leather is fixed, the lifting plate 5 is controlled to move down, so that the roller at the top of the linkage rod 19 moves along the inclined side of the push block 16. The rolling motion of the two stretching seats 18 allows the linkage rod 19 to push the stretching seat 18 to slide along the surface of the arched frame 2. At this time, the two stretching seats 18 can automatically stretch and flatten the artificial leather. When the stretching seat 18 cannot move, the lifting rod 15 and the lifting plate 5 can elastically extend and retract to prevent the lifting plate 5 from getting stuck when it continues to move down. When the stretching seat 18 moves and stretches the artificial leather, the clamping plate 23 at the lower end of the stretching seat 18 will cooperate with the fixing plate 24 to squeeze the liquid bladder 25, so that the polishing agent inside the liquid bladder 25 can be evenly sprayed onto the surface of the artificial leather through the spray pipe 26, which is convenient for subsequent polishing. After polishing, during the resetting process of the stretching seat 18, the clamping plate 23 can stretch the liquid bladder 25, so that the liquid bladder 25 can draw the polishing agent from the liquid storage tank 27 through the pipe for subsequent reuse.

[0058] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Existing polishing machines for artificial leather processing have a single polishing direction, resulting in limited polishing efficiency and making the artificial leather prone to wrinkling during polishing. To further solve this technical problem, this example discloses the following technical content: Figures 1-4 and Figure 8 As shown;

[0059] An adjustment assembly is mounted on the threaded rod 8. A polishing roller 14 is also mounted on the adjustment assembly, and the polishing roller 14 polishes the leather surface through the drive of the adjustment assembly. The adjustment assembly includes a movable seat 9 threadedly connected to the threaded rod 8, and an adjustment plate 12 is connected below the movable seat 9. The lower end of the adjustment plate 12 is symmetrically and elastically rotatably connected to a movable frame 13, and the lower end of the movable frame 13 is fixedly connected to the polishing roller 14.

[0060] Two telescopic rods 10 are symmetrically installed on the movable seat 9, and the lower end of the telescopic rod 10 is fixedly connected to the upper surface of the adjusting plate 12. A first spring 11 is connected between the upper end of the telescopic rod 10 and the movable seat 9. Meanwhile, inverted triangular abutment blocks 501 are evenly fixedly installed on the lower surface of the lifting plate 5. During the movement of the movable seat 9, the upper end of the telescopic rod 10 slides against the inclined surface of the abutment block 501.

[0061] By adopting the above technical solution, after the artificial leather is fixed, the motor 7 is started, which drives the threaded rod 8. The threaded rod 8 drives the movable seat 9 to move back and forth through the threaded connection. At this time, the polishing roller 14 can rub and polish the surface of the artificial leather. As the movable seat 9 moves, the top of the telescopic rod 10 set on it will slide against the inclined surface of the contact block 501, so that the telescopic rod 10 drives the adjusting plate 12 to move back and forth under the elastic force of the first spring 11. The movable frame 13 below the adjusting plate 12 can be elastic, so that the polishing roller 14 can automatically polish the surface of the artificial leather in multiple directions, which effectively improves the polishing efficiency.

[0062] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
