Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for leather production and processing, and in particular to an environmentally friendly leather grinding machine. Background Technology

[0002] Environmentally friendly leather refers to genuine leather where the levels of chemicals closely related to the environment are below the limits. Only such leather can be accepted by EU countries and is known as true "eco-leather," or environmentally friendly leather. As consumers pay more attention to environmental protection and sustainable development, they have higher requirements for the environmental performance and quality of leather products, as well as the aesthetics and durability of leather. To meet these consumer demands, leather needs to be polished. In order to reduce the physical effort required for polishing, leather polishing machines were invented.

[0003] A leather buffing machine is used to rub the surface of leather with sandpaper. This includes surface buffing, lining buffing, and napping. Surface buffing grinds the grain surface of the leather, generally removing minor imperfections. Lining buffs the flesh side of the leather to make the leather's thickness uniform and the inside clean. Nail buffing mainly includes front and back napping, which refers to creating a uniform and fine nap on the grain or flesh side of the leather. Early leather buffing machines used relatively coarse materials for the buffing rollers and abrasives, and the sandpaper, abrasive cloth, and abrasive particles were uneven, resulting in uneven surface buffing and localized over- or under-buffing. To address these early buffing issues... The problems of unevenness and insufficient polishing are addressed by using high-strength and high-precision metal materials on the market. These materials undergo precision machining and heat treatment to give the polishing rollers good rigidity, wear resistance, and dimensional stability, ensuring that they will not deform during long-term polishing. However, a single polishing roller is difficult to optimize and adjust for these differences, so it cannot meet the polishing requirements of various thicknesses and types of leather. This results in poor polishing effects, increases raw material costs, and frequent downtime for adjustments and equipment wear and tear also increases maintenance and equipment replacement costs.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an environmentally friendly leather polishing machine, comprising a housing 1. Two rotating rods 10 are rotatably connected to the inner bottom wall of the housing 1. A conveyor belt 3 is rotatably connected to the middle of the two rotating rods 10. A motor 9 is fixedly connected to the front left side of the housing 1. The output end of the motor 9 is fixedly connected to the left end of the front rotating rods 10. When leather is manually placed onto the conveyor belt 3, the motor 9 drives the rotating rods 10 to rotate, which in turn drives the conveyor belt 3 to rotate, transporting the leather to the designated location. The next step is to proceed to the required parts. Threaded rods 17 are rotatably connected to the middle of the left and right sides of the inner wall of the outer casing 1. A knob 4 is fixedly connected to the far end of each threaded rod 17. A slider 5 is threadedly connected to the outer wall of the threaded rod 17. A grinding device 7 is fixedly connected to the bottom of the slider 5. Rotating rods 6 are fixedly connected to the left and right sides of the grinding device 7. Rotating the knob 4 drives the threaded rod 17 to rotate. Simultaneously, the rotation causes the slider 5 to translate. The translation of the slider 5 causes the grinding device 7 on the rotating rod 6 to move, displacing it onto the outer casing. The leather in the middle of the outer shell 1 is polished. Two limiting plates 8 are fixedly connected to the middle of the inner top wall of the outer shell 1. The adjacent ends of the two rotating rods 6 in the middle are slidably connected to the corresponding limiting plates 8. Two sliding grooves 11 are opened on the front and rear sides of the inner side of the outer shell 1. The top of the slider 5 is slidably connected to the sliding groove 11. When the knob 4 is rotated manually, the threaded rod 17 will rotate together. When the threaded rod 17 rotates, it will drive the slider 5 on the threaded rod 17 to move internally in the sliding groove 11, thereby pushing the polishing of the bottom of the slider 5. To prevent excessive translation of the grinding equipment 7 and its slippage, a limiting plate 8 is fixed in the left and right directions of the threaded rod 17 to limit the translation range of the grinding equipment 7. A cleaning mechanism 2 is provided in the middle of the left side of the outer shell 1. The cleaning mechanism 2 is used to improve the cleaning power and practicality of the equipment. Multiple iron plates 15 are fixedly connected to the front and rear sides of the outer shell 1. Tripods 16 are fixedly connected to the opposite sides of the multiple iron plates 15. The cooperation between the tripods 16 and the iron plates 15 can fix the equipment and prevent displacement when the equipment ages.

[0033] Specifically, when the leather is manually placed on the conveyor belt 3 for transport, the motor 9 is turned on. The start of the motor 9 drives the two rotating rods 10 to rotate, thereby transporting the leather through the conveyor belt 3 to the middle of the polishing equipment 7. Then, the threaded rod 17 is rotated by manually rotating the knob 4. As the threaded rod 17 rotates, the slider 5 on the threaded rod 17 moves inside the sliding groove 11 inside the outer shell 1. As the slider 5 moves, the polishing equipment 7 on the rotating rod 6 slides parallel to each other. When the polishing equipment 7 slides to a certain position, the sliding of the polishing equipment 7 is restricted by the limiting plate 8, which can prevent the polishing equipment 7 from moving horizontally again after moving to the position, which would cause the equipment to fall off and cause equipment failure. When the polishing equipment 7 slides to the middle of the equipment, the leather transported by the conveyor belt 3 is polished. The iron plate 15 on the equipment is in close contact with the equipment, and the tripod 16 is in close contact with the ground. The cooperation of the iron plate 15 and the tripod 16 can fix the equipment and prevent the equipment from shifting when it ages.

[0034] Reference Figure 4 , Figure 5 and Figure 6The cleaning mechanism 2 includes a fan 201. The outer wall of the fan 201 is fixedly connected to the middle left side of the outer casing 1. When the fan 201 is turned on, it blows air in one direction to facilitate collection of the polished leather shavings. A collection groove 25 is provided on the right side of the inner bottom wall of the outer casing 1. The collection groove 25 can collect the leather shavings blown by the fan 201. Square fixing plates 13 are fixedly connected to the top front and rear sides of the top of the collection groove 25. Swing cylinders 202 are fixedly connected to the top of the two square fixing plates 13. L-shaped fixing devices are fixedly connected to the top of the two swing cylinders 202. The fixed plate 203 is driven to swing by the swing cylinder 202. Guide plates 204 are fixedly connected to the left sides of both L-shaped fixed plates 203. As the L-shaped fixed plates 203 swing, they also drive the guide plates 204 to swing. The swinging of the guide plates 204 causes them to shift, guiding leather shavings towards the fan 201. Two threaded holes 206 are provided on the opposite sides of each L-shaped fixed plate 203. Multiple screws 205 are threaded to the front and rear sides of both L-shaped fixed plates 203. Multiple screws 205 are threaded onto their adjacent sides and connected to corresponding threaded holes 206. By manually tightening the screws 205, they emerge from the threaded holes 206, allowing the guide plate 204 to be removed for cleaning and quick disassembly. A vacuum cleaner 207 is located on the right side of the housing 1. Using the direction of the fan 201 and the guide plate 204, it blows leather shavings into the collection trough 25, where they are then absorbed by the vacuum cleaner 207. The cleaning mechanism 2 also includes a sponge pad 24, the top of which is fixedly connected to... At the bottom of the guide plate 204, a sponge pad 24 is added to the bottom of the guide plate 204. This can reduce the friction between the guide plate 204 and the equipment, and also prevent leather shavings from being blown around by the wind by leaving no gaps at the bottom of the guide plate 204. Multiple pin strips 20 are rotatably connected to the top front end of the outer wall of the outer shell 1. Two dustproof plates 18 are fixedly connected to the front and rear sides of the outer shell 1. Door handles 19 are fixedly connected to the front and rear sides of the two dustproof plates 18. By rotating the pin strips 20 and pulling the door handles 19 downward, the dustproof plates 18 will be pulled. The dustproof plates 18 can prevent dust and prevent leather shavings from flying around.

[0035] Specifically, when the sanding equipment 7 performs sanding, it generates many fine leather shavings. Failure to clean these shavings can lead to mechanical malfunctions and safety issues. To address this, the fan 201 is activated, using its own airflow to blow the shavings to a designated area for collection. To prevent the shavings from scattering, the swing cylinder 202 swings the L-shaped fixed plate 203. Simultaneously, the guide plate 204 on the L-shaped fixed plate 203 swings as well. This swinging motion prevents the leather from flying around and gathers the shavings in one location. This allows the fan 201 to blow air into the collection tank 25. The guide plate 204 is threadedly connected to the L-shaped fixing plate 203 with screws 205, which also allows for quick replacement and maintenance of the guide plate 204. The vacuum cleaner 207 is then turned on to collect leather shavings inside the collection tank 25. The sponge pad 24 at the bottom of the guide plate 204 helps with cleaning and also prevents friction between the guide plate 204 and the equipment. By turning the latch bar 20 and pulling the door handle 19 downward, the dustproof plate 18 can be moved. Closing the dustproof plate 18 prevents leather shavings from flying outside.

[0036] Reference Figure 1 and Figure 2 A mounting base 22 is fixedly connected to the top front side of the outer casing 1. A warning light 21 is fixedly connected to the top of the mounting base 22. When the equipment malfunctions, the warning light 21 will flash and sound to prompt personnel to stop the operation and check the mechanical failure. A square fixing plate 26 is fixedly connected to the front side of the outer wall of the outer casing 1. An emergency switch 23 is fixedly connected to the front side of the square fixing plate 26. When the equipment malfunction warning light 21 sounds an alarm, the emergency switch 23 should be pressed immediately to stop the operation of the equipment.

[0037] Specifically, when the equipment malfunctions, the warning light 21 will light up. At this time, the operator will press the emergency switch 23 to stop the equipment immediately. The warning light 21 prevents the equipment from continuing to operate without the operator's knowledge when a problem occurs, which would reduce the equipment's productivity and create safety hazards.

[0038] Reference Figure 1 The top of the motor 9 is provided with a protective shell 12, and the top of the protective shell 12 is rotatably connected to a rotating door 14. By rotating the hinge, the rotating door 14 can be opened to inspect and maintain the motor 9 inside the protective shell 12.

[0039] Specifically, when motor 9 malfunctions, the hinged rotating door 14 can be opened to observe and repair motor 9. During observation and repair, motor 9 can also be maintained. The protective shell 12 can prevent motor 9 from being exposed to the outside and getting dusty, while also preventing collisions with external objects.

[0040] Working principle: Before using the device, the leather is first placed on the conveyor belt 3 by hand. The motor 9 is started and rotated, which drives the rotating rod 10 to rotate. This drives the conveyor belt 3 to transport the leather to the middle of the equipment. Then, by rotating the knob 4, the slider 5 on the threaded rod 17 is moved along the sliding groove 11, which drives the polishing device 7 to slide parallel. The limiting plate 8 limits the sliding range of the polishing device 7 to prevent the device from falling off. When the polishing device 7 reaches the middle of the outer shell 1, the leather that has been conveyed is polished, thereby improving the convenience and adaptability of the equipment.

[0041] Furthermore, the fan 201 is turned on, and the airflow from the fan 201 blows the leather shavings in one direction for collection. The swing cylinder 202 drives the L-shaped fixing plate 203 and the guide plate 204 on the L-shaped fixing plate 203 to swing. The direction of the swing guide plate 204 can better gather the leather shavings and guide them. Combined with the airflow from the fan 201, the shavings are blown into the collection tank 25. At this time, the vacuum cleaner 207 is turned on to collect the leather shavings inside the collection tank 25. The guide plate 204 and the L-shaped fixing plate 203 are connected by screws 205, which facilitates quick replacement and maintenance, thereby improving the cleanliness and safety of the equipment.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
