Description

Technical Field

[0001] The invention relates to the technical field of flexible leather processing, in particular to a flexible leather processing method and processing equipment. Background Art

[0002] Leather is a denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is made of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster, and feels comfortable. In the process of flexible leather processing, the leather needs to be softened. In the prior art, when softening the leather, most of the methods are to increase the softening effect by manual trampling. However, this method is inefficient. At the same time, during the trampling process, the softening chemical reagents are easy to splash, which is very dangerous.

A circular slot 12 is arranged at the front end of the vertical plate 11, and the driving end of the driving member 10 penetrates the vertical plate 11 and extends into the circular slot 12. A rotating handle 13 is connected to the driving end of the driving member 10, and a T-shaped frame 14 is arranged at the front end of the vertical plate 11. A strip slot 15 is arranged on the upper side of the T-shaped frame 14, one end of the rotating handle 13 penetrates the strip slot 15, and a limiting block 16 is arranged at one end of the rotating handle 13. A hammering block 17 is installed at the bottom of the T-shaped frame 14 by screws, and two T-shaped limiting blocks 18 are arranged on the lower side of the front end of the vertical plate 11, and the lower side of the T-shaped frame 14 passes between the two T-shaped limiting blocks 18; The salvage structure includes a first filter screen 19, and strip blocks 20 are connected to both sides of the first filter screen 19. A vertical rod 21 is connected to the top of the strip block 20. The top of the vertical rod 21 is connected to one side of the bottom of the lifting seat 4. Electric push rods 22 are installed on both sides of the top of the silo 6. The driving end of the electric push rod 22 is connected to a push plate 23. A recovery bin 24 is installed at the front end of the softening bin 2. The drying structure includes a door frame 25, which is arranged on the top of the recovery bin 24.

A row of connecting frames 27 are installed on the upper side of the door frame 25, and a row of hooks 28 are arranged at the bottom of the connecting frame 27. It should be noted that, during the processing of flexible leather, it is necessary to soften the flexible leather. The operator can place the flexible leather inside the softening bin 2, and then control the feeding pump 7 to operate, so that the softening chemical reagent inside the bin 6 can be sent into the softening bin 2. At the same time, the heating layer 34 operates to heat the chemical reagent, thereby increasing the softening effect of the leather. At this time, the hydraulic push rod 3 operates to drive the lifting seat 4 to descend, and the hammering block 17 extends into the softening bin 2. The driving member 10 operates to drive the rotating handle 13 to rotate inside the circular groove 12, and during the rotation process, the rotating handle 13 cooperates with the strip groove 15 and the limit block 16 to drive the T-frame 14 to reciprocate in the vertical direction, so that the leather inside the softening bin 2 can be repeatedly hammered, so that the fiber structure inside the leather can be relaxed and rearranged to a certain extent, thereby increasing the softness and ductility of the leather, and further increasing the softening effect.

A support wheel 35 is arranged on the upper side of the fixing frame 9 to increase the stability of the fixing frame 9 and the driving member 10 during the hammering process. After the beating operation is completed, the hydraulic push rod 3 runs, and can cooperate with the lifting seat 4, the vertical rod 21 and the strip block 20 to drive the first filter screen 19 to rise, and make the upper surface of the first filter plate flush with the top wall of the softening bin 2, so that the treated leather inside the softening bin 2 can be fished out, and then the electric push rod 22 runs, and the leather on the top of the first filter plate can be returned to the inside of the recovery bin 24 through the push rod. Then the operator can take out the leather and hang it on the top of the recovery bin 24 through the hook 28 for drying. The chemical reagents drained during the drying process enter the recovery bin 24 and can be re-sent into the silo 6 for recovery through the delivery pump 30. The second filter screen 29 and the detachable filtering device 31 can filter the drained chemical reagents, and finally complete the softening processing operation of the flexible leather. The device runs automatically as a whole, with high operating efficiency and good softening effect.
