Description

Technical Field

[0001] This utility model relates to the field of artificial leather production technology, and in particular to a leather grinding device for artificial leather production. Background Technology

[0002] The raw materials for manufacturing synthetic leather are usually based on polyurethane, polyvinyl chloride or other synthetic resins. After chemical processing and synthesis, these raw materials are formed into materials with the texture and appearance of leather. Through embossing or other processes, the surface of synthetic leather has a texture and feel similar to genuine leather.

[0003] The sanding device in artificial leather production is an important piece of equipment used to process textures or patterns on the surface of synthetic leather. Chinese Patent No. CN216298790U discloses a sanding device for artificial leather production. It uses limiting plates to limit the left and right movement of the artificial leather. These limiting plates are installed on both sides above the conveyor belt, and the spacing between them can be adjusted to limit the left and right movement of artificial leather of different widths, maintaining stability during the sanding process and improving the sanding quality of the artificial leather.

[0004] The printing roller is the core component of the leather smoothing device, usually made of cast iron or a special alloy. The surface of the printing roller is engraved with the desired texture or pattern. It works in conjunction with the embossing roller, and pressure is applied to bring synthetic leather or other synthetic materials into contact with the printing roller. The synthetic leather passes through the area between the embossing roller and the printing roller, and the surface texture of the printing roller is transferred to the surface of the synthetic leather. However, in existing devices, the fixed-mounted embossing roller has a large gap with the leather when smoothing thinner leather, and the leather is prone to shifting at the bottom of the embossing roller, resulting in uneven pattern distribution.

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0030] Reference Figure 1-5 This is the first embodiment of the present invention, providing a leather-grinding device for artificial leather production. The device includes a base 1 and a protective cover 2. The protective cover 2 is fixedly installed on the top of the base 1. A limiting component 3 and a driving component 4 are provided on the inner side of the protective cover 2. The driving component 4 is located on the top of the base 1. The limiting component 3 includes a pressing component 31, which includes a top plate 311 movably connected to the protective cover 2. A pressure rod 312 is provided on the inner side of the top plate 311, with an angle of 90 degrees between the pressure rod 312 and the top plate 311. A pressure plate 313 is fixedly connected to one end of the pressure rod 312 that passes through the top plate 311. The pressure plate 313 is parallel to the top plate 311. A spring 314 is provided on the outer side of the top plate 311 and the pressure plate 313. A rotating shaft 315 is provided at the bottom of the pressure plate 313. An embossing roller 316 is movably connected to the outer side of the rotating shaft 315. The top plate 311 is suspended in the protective cover 2. The pressure rod 312 runs through the entire top plate 311 and always remains perpendicular to the top plate 311 when moving. The pressure plate 313 is arranged parallel to the bottom of the top plate 311 through the pressure rod 312. When the spring 314 returns to its extended state, it pushes the pressure plate 313 connected to the spring 314 to move away from the top plate 311, so that the embossing roller 316 fits more tightly with the leather, thus ensuring a good limiting effect even when the leather is thin.

[0031] Both sides of the pressure plate 313 are movably connected to T-shaped plates 317. Embossing rollers 316 are movably connected to both ends of the rotating shaft 315 through the T-shaped plates 317. One end of the T-shaped plate 317 passes through the pressure plate 313 and protrudes from the top of the top plate 311. The T-shaped plate 317 can move in the groove in the pressure plate 313, thereby changing the distance between the embossing rollers 316 sleeved at both ends of the rotating shaft 315, thus adapting to the limiting requirements of leather of different widths. When the top of the T-shaped plate 317 is just engaged with the top of the top plate 311, the spring 314 reaches its maximum extension length, and the distance between the top plate 311 and the pressure plate 313 is at its maximum value.

[0032] Guide sliders 318 are movably connected to the inner side of each T-shaped plate 317. The guide sliders 318 are threadedly connected to the pressure plate 313 via adjusting screws 319. The guide sliders 318 can move perpendicularly to the pressure plate 313 in the grooves of the T-shaped plate 317. When the adjusting screws 319 rotate, the guide sliders 318 can drive the connected T-shaped plates 317 to move in the grooves of the pressure plate 313, thereby completing the adjustment of the distance between the embossing rollers 316.

[0033] The limiting component 3 also includes a tensioning element 32, which includes a support plate 321. The support plate 321 is movably connected to the base 1. An auxiliary roller 322 is installed on the top of the support plate 321. The auxiliary rollers 322 are symmetrically distributed on both sides of the support plate 321. A lifting arm 323 is connected to the bottom of the support plate 321. The support plate 321 can be raised and lowered on the base 1, thereby increasing the tension of the leather during conveying through the contact between the auxiliary rollers 322 and the leather, making it less likely for the leather to fall off.

[0034] The tensioning component 32 also includes a guide rail 324, which is fixedly installed in the base 1. Both ends of the guide rail 324 are provided with limit sliders 325. The limit sliders 325 are hinged to the support plate 321 through the lifting arm 323, and the limit sliders 325 are threadedly connected to the guide rail 324 through a bidirectional screw 326. One end of the bidirectional screw 326 is connected to the output shaft of a dual-axis motor. The limit sliders 325 can move along the surface of the guide rail 324, and by changing the distance between them, the angle between the lifting arm 323 and the guide rail 324 is changed, thereby lifting the support plate 321. The inner side of the limit sliders 325 is provided with threads that are compatible with the bidirectional screw 326, and the threads are opposite in direction.

[0035] The drive unit 4 includes a conveyor roller 41, which is installed in the protective cover 2 and located on the top of the base 1. A printing roller 42 is provided on the top of the conveyor roller 41. The conveyor roller 41 can be driven by a conveyor belt to drive the leather to complete the conveying. The printing roller 42 can perform pattern processing on the leather surface by rotating and contacting the leather.

[0036] The drive unit 4 also includes a motor base 43. The output shaft of an electric push rod 44 is connected to the outside of the motor base 43. A lifting screw 45 is provided at the bottom of the motor base 43. One end of the lifting screw 45 is connected to the output shaft of the motor. An L-shaped plate 46 is threadedly connected to the outside of the lifting screw 45. One end of the L-shaped plate 46 protrudes from the top of the motor base 43. The L-shaped plate 46 is fixedly installed on the outside of the top plate 311. The motor base 43 can change its position in the X-axis direction by controlling the extension length of the output shaft of the electric push rod 44. When the lifting screw 45 rotates, the L-shaped plate 46, under the constraint of the motor base 43, changes the position of the top plate 311 in the Z-axis direction, so that the embossing roller 316 can perform multi-directional abrasion treatment on the leather.

[0037] In use, the conveyor roller 41 connected to the conveyor belt is rotated by a motor, thereby conveying the leather. The leather surface is patterned through the contact between the rotating printing roller 42 and the leather. At the same time, the position of the electric push rod 44 in the X-axis direction is changed by controlling the extension length of the output shaft. The lifting screw 45 is rotated by an electric motor, which causes the L-shaped plate 46 to change the position of the top plate 311 in the Z-axis direction under the constraint of the motor base 43. This allows the embossing roller 316 to perform multi-directional abrasion treatment on the leather. The bidirectional screw 326 is rotated by a dual-axis motor, causing the threaded bidirectional screw 326 to move along the surface of the guide rail 324. As the distance between the limit sliders 325 changes, the tilt angle of the lifting arm 323 is adjusted. The change lifts the support plate 321 in the base 1. The auxiliary roller 322 contacts the leather, increasing the tension of the leather during transport, making it less likely to fall off. As the height of the top plate 311 connected to the L-shaped plate 46 decreases, the spring 314, which has returned to its extended state, pushes the pressure plate 313 connected to the spring 314 to move away from the top plate 311 under the restriction of the pressure rod 312. This makes the embossing roller 316 fit more tightly with the leather, ensuring a good limiting effect even when the leather is thin. By rotating the adjusting screw 319, the threaded guide slider 318 drives the T-shaped plate 317 to move synchronously, thereby changing the distance between the embossing rollers 316 to adapt to the limiting requirements of leathers of different widths.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
