Description

Technical Field

[0001] This utility model relates to the field of synthetic leather polishing technology, specifically to a polishing device for synthetic leather. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing, such as hair removal and tanning, and is therefore less prone to decay. Leather is composed of naturally woven protein fibers in a three-dimensional space, with a special grain layer on its surface that gives it a natural grain and luster, and a comfortable feel. However, because leather can only be obtained by killing animals, and the demand for leather has increased dramatically, scientists have developed synthetic leather.

[0003] Synthetic leather is typically made by using impregnated nonwoven fabric as the mesh layer and a microporous polyurethane layer as the grain layer. Both its front and back are very similar to leather, and it has a certain degree of breathability, making it closer to natural leather than ordinary artificial leather.

[0004] A search revealed a utility model patent with publication number CN212601118U, which discloses a polishing device for post-processing microfiber synthetic leather. The device includes a base, a conveyor frame, pressure strips, a polishing cloth, and a guide frame. The base is equipped with studs, and a floating plate is mounted on the studs. The conveyor frame is mounted on the floating plate and has a conveyor belt. The pressure strips are spaced apart on the outer surface of the conveyor belt. The polishing cloth is mounted on the pressure strips and extends outwards. The guide frame is mounted on the base and located on both sides of the conveyor frame, with guide rollers spaced vertically on each side. This utility model's polishing device for post-processing microfiber synthetic leather utilizes a conveyor belt and pressure strips to fix the polishing cloth, enabling continuous, multiple polishing operations on the surface of the microfiber synthetic leather. This improves the polishing efficiency and ensures a better polishing effect. Furthermore, it eliminates the need for multiple cloth rollers, resulting in a more compact structure.

[0005] Although the aforementioned patent uses a conveyor belt and pressure strip to fix the polishing cloth, enabling continuous and multiple polishing of the microfiber synthetic leather surface, which is beneficial to improving the polishing efficiency of microfiber synthetic leather and ensuring the polishing effect, and does not require multiple cloth rollers, making the structure more compact, the aforementioned device can only polish one surface of the synthetic leather and cannot polish both the upper and lower surfaces of the synthetic leather, resulting in low polishing efficiency of the polishing device for synthetic leather.

[0006] Therefore, it is necessary to propose a polishing device for synthetic leather to solve the above problems. Utility Model Content

Through the cooperation of the internal parts of the clamping mechanism, it is easy to clamp and transport synthetic leather, and to clean up the wrinkles and dust generated during transportation. Through the cooperation of the internal parts of the polishing mechanism, it is easy to polish both the upper and lower surfaces of the synthetic leather. It is also easy for the main body of the polishing device to select a suitable polishing plate according to the synthetic leather being transported. This solves the problem that existing devices can only polish one surface of the synthetic leather and cannot polish both the upper and lower surfaces, resulting in low polishing efficiency for synthetic leather.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a polishing device for synthetic leather, comprising a polishing device body, wherein clamping mechanisms are rotatably connected to both sides of the interior of the polishing device body, and a polishing mechanism is mechanically connected to the interior of the polishing device body via an electric push rod, and is located on the upper and lower surfaces of the synthetic leather;

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The polishing device for synthetic leather shown includes a polishing device body 1, with clamping mechanisms 2 rotatably connected to both sides inside the polishing device body 1, and a polishing mechanism 3 mechanically connected inside the polishing device body 1 via an electric push rod, located on the upper and lower surfaces of the synthetic leather.

[0029] The clamping mechanism 2 includes a clamping plate 201, which is mechanically fixed to both sides of the inside of the polishing device body 1 by a telescopic cylinder and is located at the top and bottom of the synthetic leather. Multiple clamping rollers 202 are rotatably connected inside the polishing device body 1 and are located on one side of the clamping plate 201 and are sleeved and fitted against the outer wall of the synthetic leather. Cleaning modules 205 are mechanically connected to the surface of the clamping rollers 202 and are symmetrically distributed.

[0030] The polishing mechanism 3 includes a fixed bracket 301, which is mechanically connected to the interior of the polishing device body 1 via an electric push rod and is distributed at the top and bottom of the synthetic leather. A polishing plate 302 is rotatably connected to the bottom of the fixed bracket 301. A connecting column 303 is welded and fixed to the top of the polishing plate 302. A servo motor 304 is bolted inside the fixed bracket 301. The output end of the servo motor 304 is rotatably connected to a drive shaft 305 via a coupling. The connecting column 303 is slidably sleeved with the outer wall of the drive shaft 305. Arc-shaped sliders 307 are mechanically fixed on both sides of the inner wall of the top of the connecting column 303 and are slidably connected to the outer wall of the drive shaft 305. A support spring 306 is mechanically fixed inside the connecting column 303 and is located at the bottom of the drive shaft 305.

[0031] The interoperability of the internal parts of the clamping mechanism 2 facilitates the clamping and transportation of synthetic leather, and also facilitates the cleaning of wrinkles and dust generated during transportation. The interoperability of the internal parts of the polishing mechanism 3 facilitates the polishing of both the upper and lower surfaces of the synthetic leather, and also facilitates the selection of a suitable polishing plate 302 by the main body 1 of the polishing device according to the synthetic leather being transported.

[0032] Refer to the instruction manual appendix Figure 1-5 The clamping mechanism 2 also includes a drive motor 203, which is bolted inside the polishing device body 1 and its output end is rotatably connected to the clamping rollers 202 via a coupling. The outer walls of the multiple clamping rollers 202 are all fitted with transmission gears 204, and the transmission gears 204 mesh with each other through tooth grooves. Through the mutual cooperation between the internal parts of the clamping mechanism 2, the transmission gears 204 mesh with each other, driving the clamping rollers 202 to rotate in opposite directions, thus completing the transportation of synthetic leather.

[0033] Refer to the instruction manual appendix Figure 1-5 The outer wall of the clamping roller 202 is machined with symmetrically distributed spiral patterns. The surface of the cleaning module 205 is mechanically connected with small flexible brushes. The symmetrically distributed spiral patterns on the outer wall of the clamping roller 202 and the small flexible brushes on the surface of the cleaning module 205 facilitate the rotation of the clamping roller 202 to smooth the wrinkles on the surface of the synthetic leather through the spiral patterns. The brushes on the surface of the cleaning module 205 facilitate the cleaning of dust on the surface of the synthetic leather, thereby improving the polishing quality of the synthetic leather.

[0034] Refer to the instruction manual appendix Figure 1-5 The surface of the polishing device body 1 is slidably connected to a transparent protective cover via a slide rail. The interior of the polishing device body 1 is provided with a transmission groove that matches the transmission gear 204. The transmission groove provided inside the polishing device body 1 facilitates the rotation of the transmission gear 204 inside the polishing device body 1.

[0035] Refer to the instruction manual appendix Figure 1-5 The bottom end of the fixed bracket 301 is provided with a connecting groove that matches the connecting column 303 and the polishing plate 302. The inside of the connecting column 303 is provided with a spring groove that matches the support spring 306. The connection groove provided at the bottom end of the fixed bracket 301 makes it easy to install and fix the polishing plate 302 at the bottom end of the fixed bracket 301.

[0036] Refer to the instruction manual appendix Figure 1-5 The outer wall of the drive shaft 305 is provided with multiple grooves that match the arc-shaped slider 307. The heights of the multiple grooves are not the same, and a 90-degree arc groove is provided between two grooves. The multiple grooves that match the arc-shaped slider 307 on the outer wall of the drive shaft 305, with different heights between the multiple grooves and a 90-degree arc groove between two grooves, facilitate the sliding connection of the connecting post 303 to the outer wall of the drive shaft 305 via the arc-shaped slider 307, and facilitate the connection and fixation between the connecting post 303 and the drive shaft 305.

[0037] The working principle of this practical application is as follows:

[0038] Refer to the instruction manual appendix Figure 1-5 By inserting synthetic leather into the main body 1 of the polishing device and placing it between the clamping rollers 202, and driving the clamping plates 201 to move closer together using a telescopic cylinder, the synthetic leather is clamped. The drive motor 203 is then started, which drives one of the clamping rollers 202 to rotate. The rotation of the clamping roller 202 drives the transmission gear 204, which is fixed to the outer wall, to rotate. The rotation of the transmission gear 204 meshes with each other, driving the other clamping roller 202 to rotate, thus completing the transportation of the synthetic leather. At the same time, the outer wall of the clamping roller 202 is machined with symmetrically distributed spiral patterns, which facilitates the smoothing of wrinkles generated on the surface of the synthetic leather during transportation by rotating the clamping roller 202 through the spiral patterns. The brush on the surface of the cleaning module 205 facilitates the cleaning of dust on the surface of the synthetic leather, thereby improving the polishing quality of the synthetic leather.

[0039] Refer to the instruction manual appendix Figure 1-5The polishing plate 302 is moved within the fixed bracket 301 by the worker pushing it. This allows the polishing plate 302 to move through the connection column 303 and the drive shaft 305, in conjunction with the retracting support spring 306. The connection column 303 then drives the arc-shaped slider 307 to slide within the shorter groove on the outer wall of the drive shaft 305, until it reaches one side of the arc-shaped groove. The polishing plate 302 is then rotated, causing the arc-shaped slider 307 to rotate 90 degrees within the arc-shaped groove and move into the longer groove. Releasing the pressure on the polishing plate 302 allows the support spring 306 to reset, separating the connection column 303 from the drive shaft 305. This allows the connection column 303 to slide out through the longer groove on the outer wall of the drive shaft 305 via the arc-shaped slider 307, completing the polishing process. The removal and replacement of plate 302 on the fixed bracket 301 is performed by reversing the above steps, which facilitates the installation and fixation of the replacement polishing plate 302 in the fixed bracket 301. At the same time, the connecting column 303 and the drive shaft 305 are separated by the support spring 306, so the connecting column 303 can be limited and fixed in the short groove by the arc-shaped slider 307. The fixed bracket 301 is pushed to fit against the upper and lower surfaces of the synthetic leather by the electric push rod, and the servo motor 304 is started. The servo motor 304 drives the drive shaft 305 to rotate. The rotation of the drive shaft 305 drives the connecting column 303 to rotate through the arc-shaped slider 307. The rotation of the connecting column 303 drives the polishing plate 302 to rotate, thus completing the polishing operation of the upper and lower surfaces of the synthetic leather at the same time, improving the polishing efficiency of the main body 1 of the polishing device for synthetic leather.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
