Description

Technical Field

[0001] This utility model belongs to the technical field of leather processing equipment, specifically a leather sanding and leveling machine. Background Technology

[0002] Leather smoothing and leveling machines are key pieces of equipment in the leather industry, primarily used for grinding, polishing, and leveling leather surfaces to eliminate imperfections, adjust thickness, and improve surface texture. They achieve a uniform and smooth finish through mechanical grinding and are widely used in footwear, bags, furniture leather, and automotive interior leather products.

[0003] In existing technology, the leather surface is usually ground and polished by a combination of abrasive rollers and polishing rollers. After grinding and polishing, the leather surface is then leveled. The abrasive rollers and polishing rollers inside the leather grinding and leveling machine need to be height-adjusted to suit leathers of different thicknesses. However, the conventional adjustment method is to manually turn the bolts to adjust the abrasive rollers and polishing rollers. This adjustment method requires stopping the machine, which reduces the efficiency of grinding and leveling the leather surface and cannot achieve automated adjustment. Summary of the Invention

[0004] The purpose of this invention is to provide a leather sanding and leveling machine, which has an automatically adjustable height for sanding rollers and polishing rollers, making it suitable for sanding and polishing leather of different thicknesses.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A leather smoothing and leveling machine is provided, comprising a support frame, a conveying mechanism installed inside the support frame, a cover fixedly connected to the upper surface of the support frame, a smoothing mechanism, a dust extraction mechanism, and a leveling mechanism installed inside the cover, an infrared sensor fixedly connected inside the cover, and a second motor, the main body of which is fixedly connected to the upper surface of the cover, and a lead screw fixedly connected to the output end of the second motor, the lead screw being rotatably connected inside the cover, and a lead screw being rotatably connected inside the cover. Second, lead screw one and lead screw two are connected by two synchronous pulleys and a synchronous belt. Two guide rods are fixedly connected to the lower surface of the cover. Connecting frames are slidably connected to the outer walls of the two guide rods. The two connecting frames are threaded to the outer walls of lead screw one and lead screw two, respectively. Motor three is fixedly connected to the outer wall of one of the connecting frames. A grinding roller is fixedly connected to the output end of motor three. The grinding roller is rotatably connected inside the two connecting frames. A polishing roller is rotatably connected inside the two connecting frames. The grinding roller and the polishing roller are connected by two synchronous pulleys and a synchronous belt.

[0006] Optionally, the conveying mechanism includes a motor, the main body of which is fixedly connected to the outer wall of the support, and the output end of which is fixedly connected to a conveying roller, which is rotatably connected inside the support.

[0007] Optionally, a second conveyor roller is rotatably connected inside the bracket, and a conveyor belt is rotatably connected to the outer walls of the first and second conveyor rollers. A support plate is fixedly connected inside the bracket, and the inner wall of the conveyor belt is slidably connected to the outer wall of the support plate.

[0008] Optionally, the vacuuming mechanism includes a vacuum pump, the main body of which is fixedly connected to the upper surface of the housing, the air inlet of which is fixedly connected to a vacuum hood, the outer walls of which are fixedly connected to the inside of the housing, and the vacuum hood is located on the right side of the abrasion mechanism.

[0009] Optionally, the air outlet of the vacuum pump is fixedly connected to a conveying pipe, the upper surface of the cover is fixedly connected to a dust collection box, the end of the conveying pipe away from the vacuum pump is fixedly connected to the inside of the dust collection box, and a dust collection container is slidably connected inside the dust collection box.

[0010] Optionally, an infrared sensor two is fixedly connected to the lower surface of the cover. The infrared sensor two is located on the left side of the leveling mechanism. The leveling mechanism includes a cylinder. The main body of the cylinder is fixedly connected to the lower surface of the cover. A leveling iron is fixedly connected to the telescopic end of the cylinder. A leveling plate is fixedly connected to the lower surface of the leveling iron.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, after infrared sensor one detects that the leather is close to the grinding mechanism, motor two is started to drive lead screw one to rotate. The rotation of lead screw one synchronously drives lead screw two to rotate, which in turn drives the two connecting frames to move down, causing the sanding roller and polishing roller to move down and make the bottom of the sanding roller and polishing roller contact the leather surface. Motor two stops rotating, and then motor three is started to drive the sanding roller to rotate. The rotation of the sanding roller synchronously drives the polishing roller to rotate, thereby realizing the sanding and polishing work of the leather surface. By automatically adjusting the height of the sanding roller and polishing roller, the sanding and polishing work of leather of different thicknesses can be carried out, without the need to stop the machine for manual adjustment, thus improving the efficiency of sanding and polishing work.

[0013] 2. In this utility model, the leather is continuously conveyed through the conveying mechanism. When the grinding mechanism is grinding and polishing the surface of the leather, the dust pump is started to suck up the debris and dust generated during grinding and polishing through the dust hood and convey it to the inside of the dust collection box and dust collection container through the conveying pipe. After the part of the leather that has been ground and polished passes through the second infrared sensor, the cylinder is started to drive the leveling iron and the leveling plate to move down, so that the leveling plate contacts the surface of the leather. Then, combined with the conveying mechanism to convey the leather, the leather is leveled. Attached Figure Description

[0026] The present invention will now be described. A leather smoothing and finishing machine includes a support frame 1. A conveying mechanism 2 is installed inside the support frame 1 for conveying leather. A cover 101 is fixedly connected to the upper surface of the support frame 1. A smoothing mechanism 3, a dust extraction mechanism 4, and a finishing mechanism 5 are installed inside the cover 101. The smoothing mechanism 3 performs grinding and polishing work on the leather surface, while the dust extraction mechanism 4 removes the dust generated during grinding and polishing. The ground and polished leather is conveyed to the finishing mechanism 5 via the conveying mechanism 2, where the finishing mechanism 5 finishes the leather. An infrared sensor 102 is fixedly connected inside the cover 101. Figure 4As shown, the skin smoothing mechanism 3 includes a second motor 301. The main body of the second motor 301 is fixedly connected to the upper surface of the cover 101. The output end of the second motor 301 is fixedly connected to a first lead screw 302.

A second lead screw 303 is rotatably connected inside the cover 101 and is limited to rotate inside the cover 101. The first lead screw 302 and the second lead screw 303 are connected by two synchronous pulleys and a synchronous belt. Motor 2 301 drives lead screw 1 302 to rotate, causing lead screw 1 302 to drive two synchronous pulleys and a synchronous belt to rotate, which in turn drives lead screw 2 303 to rotate synchronously. Two guide rods 304 are fixedly connected to the lower surface of the cover 101. Connecting brackets 305 are slidably connected to the outer walls of the two guide rods 304 respectively. The two connecting brackets 305 are threadedly connected to the outer walls of lead screw 1 302 and lead screw 2 303 respectively.

The motor 306 drives the sanding roller 307 to rotate, which in turn drives the two synchronous pulleys and the synchronous belt to rotate, thereby driving the polishing roller 308 to rotate synchronously. Polishing can be performed immediately after the leather is sanded.

[0027] The leather grinding and smoothing machine provided by this utility model, compared with the prior art, solves the problem of needing to stop the machine in the existing manual adjustment method by automatically adjusting the height of the grinding roller 307 and the polishing roller 308, thereby improving the working efficiency of grinding, polishing and smoothing the leather surface.

A conveyor belt 203 is rotatably connected to the outer walls of the first and second conveyor rollers 202 and 204. The operating principle of the conveyor rollers 202, 204, and 203 is the same as that of two synchronous pulleys and a synchronous belt. The motor 201 drives the first conveyor roller 202 to rotate, which in turn drives the conveyor belt 203 to rotate the second conveyor roller 204, thus transporting the leather. A support plate 104 is fixedly connected inside the support 1. The inner wall of the conveyor belt 203 is slidably connected to the outer wall of the support plate 104. The support plate 104 supports the inside of the conveyor belt 203, assisting in grinding, polishing, and finishing. In the flat operation, the vacuuming mechanism 4 includes a vacuum pump 401. The main body of the vacuum pump 401 is fixedly connected to the upper surface of the housing 101. A vacuum hood 402 is fixedly connected to the air inlet of the vacuum pump 401.

The main body end of the cylinder 501 is fixedly connected to the lower surface of the cover 101. The telescopic end of the cylinder 501 is fixedly connected to a leveling iron 502. A leveling plate 503 is fixedly connected to the lower surface of the leveling iron 502.

[0029] Working Principle: All internal components of the leather smoothing and sizing machine are connected to a remote control device. Starting motor 201 drives conveyor roller 202, conveyor belt 203, and conveyor roller 204 to rotate. The leather is then placed on the surface of conveyor belt 203, which transports the leather into the housing 101 during rotation. Once the leather is transported to a position detectable by infrared sensor 102, starting motor 301 drives lead screw 302 to rotate, which in turn drives lead screw 303 to rotate. This causes the two connecting frames 305 to move downwards, which in turn moves the sanding roller 307 and polishing roller 308 downwards, bringing them into contact with the leather surface. Simultaneously, starting motor 306 drives the sanding roller 307 to rotate, which in turn drives the polishing roller 308 to rotate. The rotation of the sanding roller 307 then polishes the leather surface. The grinding process continues, and the ground leather portion is transported by conveyor belt 203 through polishing roller 308. Polishing roller 308 polishes the surface of the ground leather portion. Simultaneously with grinding and polishing, dust pump 401 is activated. Dust generated during grinding and polishing is removed by dust pump 401 in conjunction with dust hood 402 and transported through conveyor pipe 403 to the interior of dust collection box 404 and dust collection container 405. The dust collection container 405 is periodically pulled out to clean the dust inside. As the ground and polished leather portion continues to be transported by conveyor belt 203, it passes through infrared sensor 103. When infrared sensor 103 detects the passing of the leather, cylinder 501 is activated to move leveling iron 502 and leveling plate 503 downward, causing the lower surface of leveling plate 503 to contact the leather surface. Combined with the transport of the leather by conveyor belt 203, the leather surface is leveled. After leveling, conveyor belt 203 continues to transport the leather to the outside of cover 101 for unloading.
