Abstract
Description
Technical Field
[0001] The invention relates to the field of leather processing technology, specifically to a leather splitting device. Background Technology
[0002] Leather is animal hide that has been denatured and is not easily perishable, obtained through physical and chemical processing such as hair removal and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster, and a comfortable feel. When processing leather, leather polishing is an indispensable process, and polished leather will have a good texture.
[0003] Some existing leather splitting machines on the market cause leather to shift and wrinkle during the splitting process due to its softness. This makes it impossible to produce usable leather in subsequent cutting and processing. In addition, the waste generated during the splitting process tends to accumulate on the splitting device, which can affect the processing accuracy of the leather and increase the time required to clean the worktable. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a leather slicing device. This device solves the technical problems that leather, due to its inherent softness, is prone to shifting and wrinkling during the slicing process. As a result, the entire piece of leather to be processed cannot produce usable leather in subsequent cutting and processing. Furthermore, the waste generated during the slicing process tends to accumulate on the slicing device, which can affect the processing accuracy of the leather and increase the time required to clean the workbench.
[0005] To achieve the above objectives, the invention adopts the following technical solution:
[0006] A leather slicing device includes a workbench with a housing fixedly mounted thereon. Two opposing fixed blocks are mounted on the top of the housing, and a first rotating shaft rotatably connects the two fixed blocks. A first rotating roller for placing leather to be processed is fixedly mounted on the first rotating shaft. A lifting assembly is mounted on the housing, and an extension block is mounted on the lifting assembly. A slicing knife is mounted on the extension block. A first guide assembly is mounted at the bottom of the lifting assembly, and a second guide assembly is mounted at the bottom of the housing, with the first and second guide assemblies facing each other. A drive assembly is mounted on the rear wall of the housing. Two opposing conveyor belts are mounted inside the housing, each conveyor belt comprising several track wheels and tracks. The track wheels are rotatably mounted on the inner wall of the housing, and the track is wound around the corresponding track wheel. The housing also includes a fixed rod, a first column, a limiting sleeve, a telescopic spring, a second column, and a pressure plate. The fixed rod is fixed to the track, the first column is connected to one end of the fixed rod, the top of the telescopic spring is fixedly mounted on the bottom of the first column, the limiting sleeve is fixedly mounted on the outer wall of the first column, the top of the second column is fixedly connected to the bottom of the telescopic spring, and the second column slides through the limiting sleeve. The pressure plate is fixedly mounted on the bottom of the second column. The conveyor belt is located between the fixed block and the first guide assembly. The drive assembly is fixedly connected to one of the track wheels. A crank-slider mechanism for cleaning the surface of the workbench is also installed inside the housing.
[0007] Working principle:
[0008] When operators need to stabilize the leather to be processed and clean up the dust generated during processing, they first place one side of the leather on the first rotating shaft or the first rotating roller. Since different leathers have different sizes, leathers of different sizes can be placed on first rotating shafts and rollers of different diameters. During operation, the operator first winds each piece of leather onto the first rotating shaft or roller according to its size. Then, the leather is placed between two opposing conveyor belts, with one side of the leather also passed between the first and second guide components. The operator then simultaneously starts the conveyor belts and the lifting assembly. The conveyor belt moves the fixed rod, which in turn moves the first column, limit sleeve, telescopic spring, second column, and pressure plate. This method stabilizes the leather to be processed. The lifting assembly further stabilizes the leather. When the leather splitting process begins, the already moving conveyor belt simultaneously drives the crank-slider mechanism. The crank-slider mechanism removes dust and debris generated on the worktable during processing. This method not only stabilizes the leather to be processed to prevent wrinkles but also cleans up the dust and debris generated during processing, ensuring that waste does not accumulate in the device and thus does not affect processing accuracy.
[0009] The beneficial effects of the invention are:
[0010] Compared with some existing technologies, this method allows users to steadily move the leather to be processed by moving the conveyor belt, while simultaneously driving the crank-slider mechanism to clean up the waste generated during the processing of the leather. This not only prevents the leather from wrinkling during processing, but also prevents the accumulation of waste during processing, thus preventing any impact on the processing accuracy of the device.

[0015] The technical solution of the invention will be further described below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1As shown, a leather slicing device includes a workbench 1, a housing 2 fixedly mounted on the workbench 1, two opposing fixed blocks 3 mounted on the top of the housing 2, a first rotating shaft 4 rotatably mounted between the two fixed blocks 3, a first rotating roller 5 for placing the leather to be processed fixedly mounted on the first rotating shaft 4, a lifting assembly mounted on the housing 2, the lifting assembly including a cylinder 15, a horizontal support block 16, and two vertical support blocks 17, the cylinder 15 fixedly mounted on the top of the housing 2 with its extension end vertically downward through the housing 2, the horizontal support block 16 fixedly mounted on the extension end of the cylinder 15, the two vertical support blocks 17 respectively fixed on both sides of the horizontal support block 16, a first guide assembly connected to the two vertical support blocks 17, an extension block 39 mounted on the lifting assembly, a slicing blade 6 mounted on the extension block 39, and a first guide assembly mounted at the bottom of the lifting assembly. The component includes a second rotating shaft 18 and an upper guide roller 19. The two ends of the second rotating shaft 18 are rotatably mounted between two vertical support blocks 17. The upper guide roller 19 is fixedly mounted on the second rotating shaft 18. A second guide assembly is installed at the bottom of the housing 2. The second guide assembly includes a third rotating shaft 20 and a lower guide roller 21. The third rotating shaft 20 rotatably passes through the housing 2 and is parallel to the second rotating shaft 18. The lower guide roller 21 is fixedly mounted on the third rotating shaft 20. Opposite to the upper guide roller 19, a drive assembly is installed on the rear wall of the housing 2. The drive assembly includes a drive motor 22 and a drive shaft 23. The drive motor 22 is fixed on the rear wall of the housing 2. The drive shaft 23 is fixedly installed on the output end of the drive motor 22 and rotates through the housing 2. The drive shaft 23 is fixedly connected to the track wheel 7 located at the edge end on the conveyor belt above, and the drive shaft 23 is parallel to the third shaft 20 and the second shaft 18.
[0017] When users need to stabilize the leather to be processed and clean up the dust generated during processing, the operator first places one side of the leather to be processed on the first rotating shaft 4 or the first rotating roller 5. Since different leathers have different sizes, leathers of different sizes can be placed on the first rotating shaft 4 and the first rotating roller 5 of different diameters. During operation, the operator first winds each piece of leather to be processed onto the first rotating shaft 4 or the first rotating roller 5 according to its size. Then, the leather is placed between two opposing conveyor belts, and one side of the leather is also passed between the first guide assembly and the second guide assembly. Next, the operator simultaneously starts the conveyor belts and the lifting assembly. The conveyor belt drives the fixed rod 9 to move, and the fixed rod 9 drives the first column 10, the limit sleeve 11, the telescopic spring 12, and the second... The column 13 and pressure plate 14 move, and the telescopic end of the cylinder 15 drives the horizontal support block 16 to move vertically. The horizontal support block 16 drives two vertical support blocks 17 to move, and the two vertical support blocks 17 drive the second rotating shaft 18 and the upper guide roller 19 to move vertically. In this way, the leather to be processed can be stabilized. The lifting component can further stabilize the leather to be processed. When the leather splitting process begins, the already moving conveyor belt simultaneously drives the crank-slider mechanism to move. The crank-slider mechanism removes the dust generated on the worktable 1 during processing. In this way, not only can the leather being processed be stabilized to prevent wrinkles, but the dust generated during processing can also be cleaned up, so as to ensure that waste does not accumulate in the device and thus does not affect the processing accuracy.
[0018] like Figure 1 and Figure 2As shown, the housing 2 is equipped with two vertically opposed conveyor belts. Each conveyor belt includes several track rollers 7 and tracks 8. The track rollers 7 are rotatably mounted on the inner wall of the housing 2, and the tracks 8 are wound around the corresponding track rollers 7. The housing also includes a fixing rod 9, a first column 10, a limiting sleeve 11, a telescopic spring 12, a second column 13, and a pressure plate 14. The fixing rod 9 is fixed to the tracks 8. The first column 10 is connected to one end of the fixing rod 9. The top of the telescopic spring 12 is fixedly mounted on the bottom of the first column 10. The limiting sleeve 11 is fixedly fitted onto the outer wall of the first column 10. The top of the second column 13 is fixedly connected to the bottom of the telescopic spring 12, and the second column 13 slides through the limiting sleeve 11. The pressure plate 14 is fixedly mounted on the bottom of the second column 13. The conveyor belt is located between the fixing block 3 and the first guide assembly. The drive assembly is connected to one of the track rollers. 7. Fixed connection: The housing 2 is also equipped with a crank-slider mechanism for cleaning the surface of the workbench 1. The crank-slider mechanism includes a disc 24, a first fixed post 25, a rocker arm 26, a second fixed post 27, a connecting rod 28, a clamp 29, two bolts 30, a cleaning rod 31, and a brush 32. The disc 24 is fixed on the drive shaft 23. The first fixed post 25 is fixed on the disc 24. One end of the rocker arm 26 is rotatably mounted on the first fixed post 25. The clamp 29 is connected to one side of one of the fixed blocks 3. The two bolts 30 pass through both sides of the clamp 29 and are screwed to the fixed blocks 3. The connecting rod 28 moves through the clamp 29. The second fixed post 27 is mounted on one end of the connecting rod 28. The other end of the rocker arm 26 is rotatably mounted on the second fixed post 27. The cleaning rod 31 is fixed on the connecting rod 28. The brush 32 is mounted on the bottom of the cleaning rod 31 and faces the workbench 1.
[0019] The drive motor 22 drives the drive shaft 23 to rotate, which in turn drives one of the track wheels 7 to rotate. This rotating track wheel 7 drives the track 8 to rotate, which in turn drives the other track wheels 7 to rotate. This method can stabilize the leather to be processed, thus preventing wrinkles. Then, the drive shaft 23 can simultaneously drive the disc 24 to rotate, which in turn drives the first fixed column 25 to rotate. The first fixed column 25 drives the rocker arm 26 to rotate, which in turn drives the connecting rod 28 to move. The connecting rod 28 drives the cleaning rod 31 and the brush 32 to move. This method can remove the waste generated during processing. In this application, the rocker arm 26 and the second fixed column 27 are hinged, which will not be described in detail here.
[0020] like Figure 1 and Figure 3As shown, it also includes a blower 33 and a blower shroud 34. The blower 33 is fixed to the workbench 1, and the blower shroud 34 is fixed inside the housing 2 and tilted towards the surface of the workbench 1. The blower shroud 34 is connected to the output end of the blower 33, and the other end of the blower 33 is connected to the outside. It also includes a guide plate 35. A long strip-shaped through hole 36 for discharging leather is opened on one side of the housing 2. The guide plate 35 is fixed inside the housing 2 and located at the bottom of the long strip-shaped through hole 36. It also includes a waste bin 37 with an opening at the top. Two chip removal strip holes 38 are opened on the workbench 1 and are located inside the housing 2. The waste bin 37 is installed at the bottom of the workbench 1 and its opening faces the two chip removal strip holes 38. It also includes a bearing 39. A mounting hole 40 is provided on one side of the first column 10. The bearing 39 is fixedly installed in the mounting hole 40. The fixing rod One end of the fixing rod 9 passes through the bearing 39 and is fixedly connected to the bearing 39. The end of the fixing rod 9 that passes through the bearing 39 is cylindrical. It also includes a first motor 41, which is fixedly installed on the rear wall of the housing 2. The output end of the first motor 41 is fixedly connected to the third rotating shaft 20. The blower 33 can blow away the waste at the edge of the workbench 1 through the blower hood 34. The guide plate 35 can sort the leather after it has been split. Then, the waste bin 37 and two chip removal strips 38 can collect the waste generated by the split leather. The bearing 39 can prevent the pressure plate 14 from tilting after it is moved by the conveyor belt, thus affecting the stability of the leather. The first motor 41 can drive the first rotating shaft 20 to rotate. The first rotating shaft 20 drives the lower guide roller 21 to rotate, thereby moving the leather to be processed.
[0021] Working principle:
[0022] When operators need to stabilize the leather to be processed and clean up the dust generated during processing, they first place one side of the leather to be processed on the first rotating shaft 4 or the first rotating roller 5. Since different leathers have different sizes, leathers of different sizes can be placed on the first rotating shaft 4 and the first rotating roller 5 of different diameters. During operation, the operator first winds each piece of leather to be processed onto the first rotating shaft 4 or the first rotating roller 5 according to its size. Then, the leather is placed between the two conveyor belts 8. Next, one end of the leather to be processed is simultaneously passed between the upper guide roller 19 and the lower guide roller 21. Then the operator... Simultaneously, the operator starts the drive motor 22, which drives the drive shaft 23 to rotate. The drive shaft 23 drives one of the track wheels 7 to rotate, and this rotating track wheel 7 drives the track 8 to rotate. The track 8 then drives the other track wheels 7 to rotate. At this time, the track wheels 7 drive the fixed rod 9 to rotate, and the fixed rod 9 drives the first column 10 to move. When the track 8 moves to a place where one side of the edge is bent, one end of the fixed rod 9 is fixedly installed in the bearing 39 of the first column 10 and will not be affected by the bend of the track 8 edge. When the fixed rod 9 is above the track 8 of the upper conveyor belt, the pressure plate 14 is activated by the extension spring 12. When the pressure plate 14 is stretched, there is a certain gap between it and the track 8 of the lower conveyor belt. When the drive motor 22 drives the drive shaft 23 to rotate, the drive shaft 23 drives the track wheel 7 located at the edge of the upper conveyor belt. In this way, the pressure plate 14 can also stabilize the leather placed on the track 8 of the lower conveyor belt. When the pressure plate 14 is moved, it can not only stabilize the leather, but also tension the leather, further preventing wrinkles from forming during processing. When the fixing rod 9 is located below the track 8 of the upper conveyor belt, the fixing rod 9 presses the first column 10, and the first column 10 presses the telescopic spring 1. 2. The second column 13 is pressed down on the pressure plate 14. Then the pressure plate 14 presses the leather to be processed onto the conveyor belt 8 below. The upper conveyor belt 8 rotates and moves the pressure plate 14 at the same time, which not only allows the pressure plate 14 to move the leather but also stabilizes the leather. Then, when the leather splitting process begins, the already moved drive shaft 23 drives the disc 24 to rotate. The disc 24 drives the first fixed column 25 to rotate. The first fixed column 25 drives the rocker arm 26 to rotate. The rocker arm 26 drives the connecting rod 28 to move. The connecting rod 28 drives the cleaning rod 31 and the brush 32 to move.
[0023] Then, the operator starts the blower 33, which blows air from inside the blower hood 34 and blows the waste on the workbench 1 into the two chip removal holes 38 and finally into the waste bin 37.
