Description

[0002] Leather is a denatured and non-perishable animal skin obtained through physical and chemical processes such as dehairing and tanning. In the process of preparing leather for shoes, the raw hide needs to be soaked in water, limed, pickled and softened before the preparation of leather for shoes can be completed.

[0003] In the prior art, in the softening process of shoe leather, it is necessary to soak the leather with a softening agent, and after soaking, the leather is manually stepped on to increase the softening effect. However, the manual stepping method is inefficient and uneven stepping occurs, which has limited effect on increasing the softening effect.

A circle of second brackets 23 corresponding to the first bracket 22 are arranged on the lower side of the main shaft 19, and fixing components are arranged at the bottom of the first bracket 22 and the top of the second bracket 23.

[0043] The fixing assembly includes a bar block 24, which is mounted on the top of the second bracket 23. A cavity 25 is provided inside the bar block 24. A transverse shaft 26 is connected to the cavity 25 through a bearing seat. Both sides of the transverse shaft 26 are connected to first conical teeth 27. Both sides of the cavity 25 are rotatably connected to screw rods 28. Second conical teeth 29 are provided on the lower side of the screw rods 28. The first conical teeth 27 are meshed with the second conical teeth 29.

[0044] A conical through hole 30 is provided on the upper side of the screw rod 28, a clamping block 31 is threadedly connected to the upper side of the screw rod 28, an opening is provided at the middle part of the top of the clamping block 31, a third conical tooth 32 is provided at the middle part of the horizontal shaft 26, a vertical rod 33 is provided at the bottom of the horizontal shaft 26, the top end of the vertical rod 33 passes through the second bracket 23 and extends into the cavity 25, the top end of the vertical rod 33 is connected to a fourth conical tooth 34, and the fourth conical tooth 34 is meshed with the third conical tooth 32;

[0045] The hammering structure includes an electric slide rail 35, a moving frame 36 is slidably connected to the bottom of the electric slide rail 35, electric push rods 37 are installed on both sides of the bottom of the moving frame 36, a lifting block 38 is connected to the bottom of the electric push rod 37, hammering components are arranged on both sides of the lifting block 38, a limited position slide 39 is arranged in parallel at the front end of the frame 1, and vertical plates 40 are slidably connected to both sides of the limited position slide 39, and the inner side of the vertical plate 40 is slidably connected to both sides of the lifting block 38;

[0046] The hammering assembly includes a second driving member 41, which is installed at the front end of the lifting block 38. The driving end of the second driving member 41 is rotatably connected to the first connecting rod 42. The front end of the lifting block 38 is rotatably connected to the rotating frame 43. One end of the first connecting rod 42 is rotatably connected to one end of the rotating frame 43 through a transmission rod. Both ends of the rotating frame 43 are rotatably connected to the second connecting rod 44. A limit block 45 is arranged at the lower side of the lifting block 38. Both sides of the limit block 45 are slidably connected to a moving rod 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.

[0047] It should be noted that in the process of preparing leather for shoes, the raw hide needs to be soaked in water, limed, pickled and softened, and after the above processes are completed, the leather needs to be softened by a softening agent. First, the operator places the two sides of the bottom of the leather inside the clamping block 31 and rotates the vertical rod 33. Then, the third conical teeth 32, the fourth conical teeth 34 and the horizontal shaft 26 cooperate to drive the two first conical teeth 27 to rotate. Then, the first conical teeth 27 will drive the screw 28 to rotate through the second conical teeth 29. Since the screw 28 is threadedly connected 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.

[0048] Since two protrusions are arranged 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 by the protrusions and shrink, and the upper opening of the clamping block 31 can be used to clamp and fix the leather, and then the same process is used to clamp and fix the top two sides of the leather. At this time, the second cylinder 8 is running, and the transmission shaft 13 can be pulled upward, and moved along the strip groove 21 and the first hanger 22 through the columnar block 20, so that the distance between the first hanger 22 and the second hanger 23 can be adjusted to keep the leather in a tensioned state, preventing the leather from shrinking and affecting the contact area with the agent, thereby affecting the softening effect;

[0049] At the same time, a tension sensor 10 is arranged between the spherical cover 11 and the second horizontal plate 9. When 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 tank 2 through the horizontal plate, and the columnar plug 51 at the bottom of the main shaft 19 is plugged into the socket 52 inside the soaking tank 2;

[0050] Then, the feeding pump 49 on the top of the medicine bin 48 is operated to feed the softening agent in the medicine bin 48 into the soaking bin through the feeding pipe 50. The softening agent is a softener composed of fatty acids, which can be combined with the fibers in the leather to increase its softness and ductility. Then, the first driving member 17 is operated to drive the main shaft 19 to rotate through the cooperation of the active gear 18 and the gear ring 14. A hexagonal prism is arranged inside the main shaft 19. The bottom of the transmission shaft 13 is plugged into the bottom of the hexagonal prism. When the main shaft 19 rotates, the transmission shaft 13 is driven to rotate synchronously. The columnar plug 51 at the bottom of the main shaft 19 cooperates with the socket 52 to increase the rotation stability of the main shaft 19. At the same time, the first bracket 22, the second bracket 23 and the strip block 24 will rotate with the main shaft 19.

[0051] Since the upper side of the transmission shaft 13 is connected to the second transverse plate 9 through the spherical block 12 and the spherical cover 11, when the main shaft 19 rotates, it will not affect the second transverse 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, it is affected by the resistance of the medicine inside the immersion tank 2, and the first bracket 22 may be against the inner wall of the strip groove 21. Long-term operation may cause the first bracket 22 to deform. For this reason, a stop block 53 is provided between the first bracket 22 and the strip groove 21 to support the first bracket 22 and prevent the first bracket 22 from deforming.

[0052] The sliding block 16 on the top of the gear ring 14 cooperates with the sliding groove 15 to provide a vertical support force for the gear ring 14 and increase the rotation stability of the gear ring 14. After the first driving member 17 rotates, the leather and the softening agent can be fully squeezed out, thereby increasing the softening effect;

[0053] After the soaking is finished, the first cylinder 5 contracts, which can drive the soaked and softened leather to rise. A notch is set on the top of the frame 1, and the inner width of the notch is greater than the upper width of the support frame 7. Therefore, after the support frame 7 is raised, there is no need to worry about the collision between the support frame 7 and the frame 1. Guide rods 56 are set on both sides of the second cylinder 8. The guide rods 56 are slidably connected with the second cross plate 9. The guide rods 56 are used to share the horizontal force generated when the transmission 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;

[0054] Then the operator takes off the leather and places the leather pair on the top of the carrying plate 4 inside the tank 3, and then drives the lifting block 38 to descend as a whole through the cooperation of the electric push rod 37 and the vertical plate 40. At this time, the second driving member 41 cooperates, and can drive the rotating frame 43 to perform reciprocating swinging motion through the cooperation of the first connecting rod 42 and the transmission rod;

[0055] Then, the two second connecting rods 44 drive the two moving rods 46 to perform reciprocating thrusting motion on the limit block 45, thereby driving the hammering block 47 to evenly and repeatedly hammer the leather accumulated on the top of the load-bearing plate 4. The mechanical hammering can directly act on the fiber structure of the leather, loosen it through physical force, and help the penetration of dyes and the adhesion of coatings in subsequent processing, and increase the softening effect. At the same time, the electric slide rail 35, the moving frame 36, the vertical plate 40 and the limit groove cooperate to drive the lifting block 38 to move in the horizontal direction, thereby increasing the hammering range and further increasing the hammering softening effect.

[0056] At the same time, the hammering will squeeze out the residual medicine inside the leather, and the medicine will be discharged through the sewage pump 55 on one side of the tank body 3. The inner wall of the bottom of the tank body 3 is set to be inclined to increase the smoothness of the medicine outflow. Both sides of the bottom end of the supporting plate 4 are provided with reinforcing ribs 54 to increase the bearing capacity of the supporting plate 4. At the same time, drainage holes are evenly opened on the top of the supporting plate 4, so that the medicine can be quickly discharged, which is convenient for the subsequent reuse of the medicine, thereby achieving the purpose of environmental protection;

[0057] In the technical solution, the spacing between the fixed components can be adjusted according to the size of the leather, so that the leather can be fully unfolded as a whole, so that the leather can be fully contacted with the softening agent inside the soaking tank 2, thereby increasing the softening effect;

[0058] After softening, the leather is placed in the tank 3 and hammered with moderate force to further increase the softening effect and ensure the quality of the leather for shoes.

[0059] The technical solution also discloses a method for preparing environmentally friendly leather for shoes, comprising the following steps:

[0060] Step S1: First, animal leather such as cowhide, pigskin, sheepskin, etc. is used as raw material, and the raw leather is preserved by basic antiseptic methods such as salting, drying, and cooling to prevent it from deteriorating;

[0061] Step S2: soaking the hides in water to reabsorb moisture and remove salt and dirt, followed by dehairing using a sulphide-based mixture or lime;

[0062] Step S3: adding acid to neutralize the alkaline substances remaining in the depilatory process, and adding a softening agent inside the preparation device, fixing the leather with the preparation device, and immersing it in the agent for full soaking, so that the leather is softened and flat;

[0063] Step S4: After the soaking is completed, the leather is subjected to a moderate and protective mechanical beating operation using a preparation device, which can promote the loosening and rearrangement of leather fibers, thereby increasing its softness and feel, and further enhancing the softening effect;

[0064] Step S5: Tanning the leather using a chrome-free tanning method (such as the simple white tanning method of Stahl Company of the Netherlands), and after the tanning is completed, the leather can be subsequently dyed and finished.

[0065] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
