Description

Technical Field

[0001] This invention relates to the field of footwear leather technology, and in particular to a preparation device and method for environmentally friendly footwear leather. Background Technology

[0002] Leather is animal hide that has been modified and is not easily perishable through physical and chemical processing such as hair removal and tanning. In the process of preparing shoe leather, the raw hide needs to be soaked in water, ash, acid, and softened before the preparation of shoe leather can be completed. In the existing technology, during the softening process of shoe leather, softening agents are used to soak the leather. After soaking, the softening effect is further enhanced by treading on it manually. However, treading on it manually is inefficient and can result in uneven treading, thus limiting the softening effect. Meanwhile, during the leather soaking process, due to the accumulation of leather pieces, the softening agent may not fully contact the leather, which can further affect the softening effect. In view of this, in-depth research was conducted on the above problems, which led to this case. Summary of the Invention

A fourth tapered tooth 34 is connected to the top of the vertical rod 33. The fourth tapered tooth 34 meshes with the third tapered tooth 32. The hammering structure includes an electric slide rail 35, a movable frame 36 slidably connected to the bottom of the electric slide rail 35, electric push rods 37 installed on both sides of the bottom of the movable frame 36, a lifting block 38 connected to the bottom of the electric push rod 37, hammering components provided on both the front and rear sides of the lifting block 38, a limit slide 39 parallel to the front end of the frame 1, vertical plates 40 slidably connected to both sides of the limit slide 39, and the inner side of the vertical plate 40 slidably connected to both sides of the lifting block 38; The hammering assembly includes a second driving component 41, which is installed at the front end of the lifting block 38. The driving end of the second driving component 41 is rotatably connected to a first connecting rod 42. The front end of the lifting block 38 is rotatably connected to a rotating frame 43. One end of the first connecting rod 42 is rotatably connected to one end of the rotating frame 43 via a transmission rod. Both ends of the rotating frame 43 are rotatably connected to second connecting rods 44. A limit block 45 is provided on the lower side of the lifting block 38. Both sides of the limit block 45 are slidably connected to moving rods 46. The bottom end of the moving rod 46 is connected to a hammering block 47. The top end of the moving rod 46 is rotatably connected to one end of the second connecting rod 44. It should be noted that in the process of preparing shoe leather, the raw hide needs to be soaked in water, soaked in ash, soaked in acid and softened. After the above processes are completed, the leather needs to be softened with a softening agent. First, the operator places the bottom two sides of the leather inside the clamping block 31 and rotates the vertical rod 33. Then, through the cooperation of the third conical tooth 32, the fourth conical tooth 34 and the horizontal shaft 26, the two first conical teeth 27 are driven to rotate. Then, the first conical teeth 27 will drive the screw 28 to rotate through the second conical tooth 29. Since the screw 28 is threaded to the bottom of the clamping block 31, when the screw 28 rotates, it will drive the clamping block 31 to retract into the conical through hole 30. Since there are two protrusions inside the tapered through hole 30, after the clamping block 31 is retracted into the tapered through hole 30, the upper side of the clamping block 31 will be squeezed and contracted by the protrusions. The upper opening of the clamping block 31 can be used to clamp and fix the leather. Then, the same process is used to clamp and fix the top two sides of the leather. At this time, the second cylinder 8 runs and can pull the drive shaft 13 upward. It can also move along the strip groove 21 and the first hanger 22 through the column block 20. This allows the distance between the first hanger 22 and the second hanger 23 to be adjusted, so that the leather is kept taut and the shrinkage of the leather affects the contact area with the agent and the softening effect. Meanwhile, a tension sensor 10 is set between the spherical cover 11 and the second horizontal plate 9. After the leather reaches the tension value, the first cylinder 5 stops running. At the same time, the first cylinder 5 runs, and the main shaft 19 and the fixed leather can be put into the soaking pool 2 through the horizontal plate, and the columnar insert 51 at the bottom of the main shaft 19 is inserted into the socket 52 inside the soaking pool 2. Subsequently, the top feeding pump 49 of the medicine tank 48 operates, sending the softening agent inside the medicine tank 48 into the soaking tank 2 through the feeding pipe 50. The softening agent is a softener with fatty acid components, which can combine with the fibers in the leather to increase its softness and extensibility. Then, the first drive component 17 operates, driving the main shaft 19 to rotate through the cooperation of the active gear 18 and the gear ring 14. The main shaft 19 is provided with a hexagonal prism inside, and the bottom of the transmission shaft 13 is inserted into the bottom of the hexagonal prism. Thus, when the main shaft 19 rotates, it will drive the transmission shaft 13 to rotate synchronously. The columnar insert 51 at the bottom of the main shaft 19 cooperates with the socket 52 to increase the rotational stability of the main shaft 19. At the same time, the first hanger 22, the second hanger 23, and the strip block 24 will rotate with the main shaft 19. Since the upper side of the drive shaft 13 is connected to the second horizontal plate 9 through the spherical block 12 and the spherical cover 11, the rotation of the main shaft 19 will not affect the second horizontal plate 9 and the second cylinder 8. At the same time, since there is a gap between the first bracket 22 and the strip groove 21, when the main shaft 19 rotates, the first bracket 22 may be able to abut against the inner wall of the strip groove 21 due to the resistance of the agent inside the soaking tank 2. Long-term operation will cause the first bracket 22 to deform. Therefore, a stop block 53 is set between the first bracket 22 and the strip groove 21 to support the first bracket 22 and prevent the first bracket 22 from deforming. The top sliding block 16 of the toothed ring 14 cooperates with the sliding groove 15, which can provide vertical support for the toothed ring 14 and increase the rotational stability of the toothed ring 14. After the first drive member 17 rotates, the leather and softening agent can be fully squeezed out, thereby increasing the softening effect. After soaking, the first cylinder 5 retracts, which can lift the softened leather. The top of the frame 1 has a notch, the inner width of which is greater than the upper width of the support frame 7. Therefore, after the support frame 7 is lifted, there is no need to worry about the support frame 7 colliding with the frame 1. The second cylinder 8 has guide rods 56 on both sides. The guide rods 56 are slidably connected to the second horizontal plate 9. The guide rods 56 are used to share the horizontal force generated when the drive shaft 13 and the main shaft 19 rotate synchronously, so as to prevent the horizontal force from affecting the operation of the second bottom rod. The operator then removes the leather and places it on top of the support plate 4 inside the tank 3. Then, through the cooperation of the electric push rod 37 and the vertical plate 40, the lifting block 38 is lowered as a whole. At this time, the second drive component 41 cooperates and, through the cooperation of the first connecting rod 42 and the transmission rod, can drive the rotating frame 43 to perform reciprocating swing motion. Then, through the two second connecting rods 44, the two moving rods 46 will reciprocate and insert on the limiting block 45, thereby driving the hammering block 47 to perform uniform and repeated hammering action on the leather piled on top of the bearing plate 4. The mechanical hammering can directly act on the fiber structure of the leather, loosening it through physical force, which helps the penetration of dye and the adhesion of coating in subsequent processing, and increases the softening effect. At the same time, the electric slide rail 35, the moving frame 36, the vertical plate 40 and the limiting groove work together to drive the lifting block 38 to move horizontally, thereby increasing the hammering range and further increasing the hammering softening effect. At the same time, the pounding will squeeze out the residual medicine inside the leather. The medicine will be discharged through the sewage pump 55 on one side of the tank 3. The bottom inner wall of the tank 3 is inclined to increase the smoothness of the medicine flow. The bottom two sides of the support plate 4 are provided with reinforcing ribs 54 to increase the load-bearing capacity of the support plate 4. At the same time, the top of the support plate 4 is evenly provided with drainage holes, which can quickly discharge the medicine and facilitate the subsequent reuse of the medicine, thereby achieving the purpose of environmental protection. In this technical solution, the spacing between the fixing components can be adjusted according to the size of the leather, so that the leather can be fully unfolded and fully contacted with the softening agent inside the soaking tank 2, thereby increasing the softening effect. After softening, the leather is placed inside the tank 3 and subjected to a moderately forceful pounding operation to further enhance the softening effect and ensure the quality of shoe leather preparation. This technical solution also discloses a method for preparing environmentally friendly leather for footwear, including the following steps: Step S1: First, cowhide, pigskin, and sheepskin are used as raw materials. The raw hides are preserved by basic anti-corrosion methods such as salting, drying, and cooling to prevent them from spoiling. Step S2: Soak the raw hide in water to reabsorb moisture and remove salt and dirt, then dehair it using a sulfide-based mixture or lime. Step S3: Add acid to neutralize the alkaline substances remaining in the hair removal process, and add softening agent inside the preparation device, fix the leather with the preparation device, and immerse it in the agent for full soaking to soften and flatten the leather; Step S4: After soaking, the leather is subjected to moderate and protective mechanical beating using a preparation device. This promotes the loosening and rearrangement of the leather fibers, thereby increasing its softness and feel, and further enhancing the softening effect. Step S5: Tanning the leather using a chromium-free tanning method (such as the simple white tanning method of Stahl AG in the Netherlands), and then performing subsequent dyeing and finishing treatments on the leather after tanning.

[0027] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
