[0002] Leather processing is a complex and delicate process that aims to transform raw animal hides into soft, durable and beautiful leather products. This process involves several key steps, among which alkali treatment is a part of the pretreatment stage. Alkali treatment usually refers to soaking the raw hide in an alkaline solution, which can improve the physical and chemical properties of the leather and lay a good foundation for its subsequent processing.

[0003] For example, the authorized patent with announcement number CN220393771U (a leather processing alkali soaking equipment) includes an alkali soaking tank, two first rollers are rotatably installed inside the alkali soaking tank, a first conveyor belt is sleeved on the outside of the two first rollers, and two shafts are rotatably installed inside the alkali soaking tank and above the first rollers.

Consequently, after alkali treatment, they cannot quickly remove the large amount of residual alkali and water on the surface and inside of the leather, increasing the difficulty and time required for subsequent washing and neutralization. Therefore, there is an urgent market need to develop an alkali soaking equipment for leather processing to help people solve the existing problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of an alkali-soaking device for leather processing, comprising an alkali-soaking tank 1, a conveyor belt 9 disposed on one side inside the alkali-soaking tank 1, a discharge slide 10 fixedly installed inside the alkali-soaking tank 1 along one side of the conveyor belt 9, an air jet assembly 11 disposed in the middle above the conveyor belt 9, and pressure assembly 12 symmetrically disposed on both sides of the air jet assembly 11, the pressure assembly 12 comprising a top plate 1201, a roller frame 1202, a pressure roller 1203, and a... The hydraulic cylinder 1204 and the roller frame 1202 are configured as a U-shaped plate. The hydraulic cylinder 1204 is externally connected to a hydraulic oil pump. The top plate 1201 is fixedly connected to the alkali immersion tank 1. The roller frame 1202 is located below the top plate 1201. The pressure roller 1203 is rotatably installed inside the roller frame 1202. The hydraulic cylinder 1204 is fixedly installed above the top plate 1201. The piston rod end of the hydraulic cylinder 1204 slides through the top plate 1201 and is fixedly connected to the roller frame 1202.

[0024] The hydraulic cylinder 1204 drives the pressure roller 1203 to roll the wet leather, which can effectively squeeze out a large amount of alkali and water absorbed by the leather, realize mechanical dehydration, reduce the amount of liquid in the leather, and help reduce the difficulty and time of subsequent washing and neutralization, thus increasing practicality.

[0025] Please see Figure 2 and Figure 3 The jet assembly 11 includes a top plate 1101, a gas distributor 1102, an air inlet pipe 1103, a jet nozzle 1104, and a connecting plate 1105. The top plate 1101 is fixedly connected to the alkali leaching tank 1. The gas distributor 1102 is located below the top plate 1101. Two air inlet pipes 1103 are provided and fixedly installed above the front and rear ends of the gas distributor 1102. The air inlet pipes 1103 are connected to a high-pressure gas supply device. Multiple jet nozzles 1104 are provided and fixedly installed below the gas distributor 1102. Two connecting plates 1105 are provided and fixedly installed between the top plate 1101 and the gas distributor 1102 at the front and rear ends.

[0026] The array of multiple jet nozzles 1104 allows for more effective removal of alkali and moisture from the leather surface through airflow impact, increasing practicality.

[0027] Please see Figure 4 The front and rear ends of the hydraulic cylinder 1204 are symmetrically provided with guide posts 13. The lower end of the guide post 13 slides through the top plate 1201 and is fixedly connected to the roller frame 1202.

[0028] During the process of hydraulic cylinder 1204 driving roller frame 1202 to rise and fall, guide column 13 can ensure that roller frame 1202 moves in the vertical direction, avoiding the roller frame 1202 from deviating or swaying during the rising and falling process, thereby ensuring the stability of pressure roller 1203 on leather.

[0029] Please see Figure 2 A feeding slide 2 is fixedly installed on one side inside the alkali soaking tank 1. The feeding slide 2 is inclined. A conveyor belt 3 is installed along one side of the feeding slide 2 inside the alkali soaking tank 1. A conveyor belt 4 is installed above the conveyor belt 3. Multiple pressure plates 5 are fixedly installed on the outside of the conveyor belt 4. The alkali soaking tank 1 contains an alkaline solution for alkali soaking leather, and the alkaline solution covers the conveyor belt 4 to facilitate the alkali soaking treatment of leather.

[0030] The feeding slide 2 allows the leather to slide smoothly into the conveyor belt 3 of the alkali soaking tank 1 by its own weight. Then the conveyor belt 3 moves the leather. At the same time, the pressure plate 5 on the outside of the conveyor belt 4 can exert a certain pressure on the leather during the conveying process, preventing the leather from floating and improving the stability of the alkali soaking treatment.

[0031] Please see Figure 2 Inside the alkali soaking tank 1, a conveyor belt 6 is installed along one side of the first conveyor belt 3. Above the third conveyor belt 6, a conveyor belt 7 is installed along one side of the second conveyor belt 4. Multiple pressure plates 8 are fixedly installed on the outside of the fourth conveyor belt 7. Both the third conveyor belt 6 and the fourth conveyor belt 7 are inclined.

[0032] The inclined conveyor belts 3-6 and 4-7 facilitate the upward transport of leather, making dehydration and output easier. Conveyor belts 3-1, 4-2, 6-3, 7-4, and 9-5 all have several through-holes to facilitate liquid flow. Both sides of the interior of each conveyor belt have troughs rotatably connected to the alkali soaking tank 1. Support rollers are installed between two belt rollers inside each conveyor belt. A drive motor for one belt roller of each conveyor belt is located at the front end of the alkali soaking tank 1. A switch cabinet for the alkali soaking equipment is also located at the front end of the alkali soaking tank 1 to facilitate normal operation of the equipment.

[0033] Working principle: During use, the leather slides onto the first conveyor belt 3 via the inclined feeding slide 2. The first conveyor belt 3 moves the leather. At this time, the pressure plate 5 on the outside of the second conveyor belt 4 presses the leather to prevent it from floating. After alkali soaking, the leather is conveyed to the third conveyor belt 6. The leather is conveyed upward by the inclined third conveyor belt 6 and the fourth conveyor belt 7. The leather is conveyed to the fifth conveyor belt 9. The fifth conveyor belt 9 carries the leather and passes through the pressing components 12 on both sides and the air jet component 11 in the middle. The hydraulic cylinder 1204 drives the pressure roller 1203 to press down steadily, squeezing out the alkali and water absorbed inside the leather. At the same time, the multiple air jets 1104 of the air jet component 11 spray high-pressure airflow, using the airflow impact to reduce the amount of liquid on the leather. Finally, the leather is output through the discharge slide 10.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
