Description

Technical Field

[0001] The utility model relates to the technical field of shoe leather, in particular to an environment-friendly pickling device for shoe leather. Background Technique

[0002] Pickling of shoe leather is a special cleaning and treatment technology. It uses acids (usually acetic acid or formic acid) to chemically react with proteins in the leather to remove surface stains and impurities, and at the same time may enhance the softness and gloss of the leather;

[0003] At present, the pickling process for shoe leather is to first put the shoe leather into a pickling tank for pickling, and then put it into a washing tank for cleaning. Each step is carried out independently, and the operator needs to continuously move the leather between steps, resulting in low overall efficiency; moreover, when the shoe leather is taken out of the pickling tank, the moisture on the surface of the shoe leather exposed to the air volatilizes quickly, easily causing the solidification of the surface acid and affecting the product quality.

[0004] Based on the above problems, there may already be technical means in the current technology to solve the above technical solutions, and this case wants to provide an alternative or replacement technical means. Content of the Utility Model

[0019] Embodiment

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: an environment-friendly pickling device for shoe leather;

[0021] This case aims to provide an environment-friendly pickling device that is conducive to the efficient pickling of shoe leather. There are many existing pickling processes for shoe leather, and the overall operation efficiency is low;

[0022] Based on the above problems, the components in this case include a main body 1. On one side inside the main body 1, there is a pickling tank 2. On one side of the pickling tank 2, there is a cleaning tank 3. On one side of the cleaning tank 3, there is a collection tank 4. On one side of the inner wall of the pickling tank 2, there is a first reversing roller 5 installed. On the bottom inner wall of the pickling tank 2, there is a second reversing roller 6. On the front and rear sides of the bottom inner wall of the cleaning tank 3, there are rotating rods 7 rotatably connected. On the lower side of the rotating rod 7, there is a limiting piece 8. On the lower side of the rotating rod 7, there is a first frame 9 sleeved. On the upper side of the rotating rod 7, there is an external thread. On the upper side of the rotating rod 7, there is a second frame 10 threadedly connected. The top end of the rotating rod 7 penetrates the wall surface of the main body 1, and the top end of the rotating rod 7 is connected to a synchronous wheel 11 and the driving end of a driving member 12. On one side of the top of the collection tank 4, there is a drying box 13, and on the other side of the top of the collection tank 4, there is an extrusion assembly;

[0023] The extrusion assembly includes a portal frame 14 installed on the other side of the top of the collection tank 4. On both sides of the portal frame 14, there are strip-shaped through holes. On the lower side of the portal frame 14, there is a first roller 15. On the upper side of the portal frame 14, there is a second roller 16. On both sides of the second roller 16, there are sliding blocks, and the sliding blocks are slidably connected to the strip-shaped through holes. On both sides of the portal frame 14, there are springs 17, and the bottom of the sliding block is connected to the spring 17;

[0024] It should be noted that during the production process of shoe leather, pickling operation needs to be carried out on the shoe leather to improve the performance and appearance of the leather. First, one end of the shoe leather is connected to the traction device. As the traction device operates, the leather will enter the pickling tank 2 in cooperation with the first reversing roller 5 and the second reversing roller 6 for immersion pickling operation. Subsequently, the pickled leather will move to the upper side of the cleaning tank 3 and be located between the first frame 9 and the second frame 10. Then, the operator can control the driving member 12 to operate, driving the rotating rod 7 to rotate. At the same time, the synchronous wheels 11 at the tops of the two rotating rods 7 are connected by synchronous belts. Therefore, when the driving member 12 operates, it can drive the two rotating rods 7 to rotate synchronously, and then drive the second frame 10 to perform vertical adjustment movement. Since both sides of the first frame 9 are sleeved on the lower side of the rotating rod 7, the first frame 9 will remain stationary when the rotating rod 7 rotates. Moreover, both the first frame 9 and the second frame 10 are connected to the water supply pump. After the leather moves to the upper side of the cleaning tank 3, the first frame 9 and the second frame 10 can cooperate to complete the water washing operation of the pickled shoe leather. The sewage washed down will enter the cleaning tank 3 for collection, and the distance between the first frame 9 and the second frame 10 is adjustable, so as to adapt to shoe leathers of various thicknesses;

[0025] After the water washing is completed, the leather will move between the first roller 15 and the second roller 16. Under the cooperation of the sliding block and the spring 17, the first roller 15 and the second roller 16 will squeeze the water-washed leather. As the leather is pulled by the traction device, the water stored in the leather will be squeezed out and enter the collection tank 4. Subsequently, the drying box 13 is used to dry the squeezed and dehydrated leather, thus completing the whole process;

[0026] Openings are provided on both sides of the main body 1. An activity door 18 is provided at the opening on one side of the main body 1. The activity door 18 can block the opening to reduce the diffusion of harmful gases. Subsequently, in cooperation with the gas collecting hood 19 connected to the exhaust fan, the harmful gases generated inside the main body 1 can be blocked and collected, so as to facilitate subsequent harmless treatment, reduce environmental pollution and ecological damage, and thus achieve the purpose of environmental protection;

[0027] Guide wheels 20 are embedded at the bottom of the strip-shaped blocks to increase the smoothness of the leather between the first frame 9 and the second frame 10 and prevent the leather from being scratched and damaged by the first frame 9 and the second frame 10.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
