Description

Technical Field

[0001] This utility model relates to an acid pickling device for leather processing, belonging to the technical field of acid pickling equipment. Background Technology

[0002] The background technology of pickling equipment for leather processing mainly originates from the pretreatment process before leather tanning. Before tanning, raw hides need to undergo a pickling process to adjust the pH of the hide fibers, making them suitable for the full penetration and binding of tanning agents (such as chrome tanning agents), thereby improving the leather's flexibility, stability, and durability. Traditional pickling methods mostly rely on manual labor or simple containers, resulting in problems such as uneven acid distribution, low processing efficiency, and serious environmental pollution. Therefore, specialized pickling equipment has gradually been developed to achieve acid circulation, stirring, and uniform penetration, thereby improving processing quality and production efficiency while reducing acid waste and operational risks.

[0003] Existing leather pickling equipment requires manual placement of leather into the acid tank, which has significant drawbacks: First, operators are in direct contact with the acidic environment, which can easily lead to skin burns or inhalation of harmful gases, posing a significant safety hazard; second, manual placement is inefficient and labor-intensive, making it difficult to meet the needs of large-scale production; third, manual operation makes it difficult to ensure the uniformity and consistency of leather placement, which can easily result in insufficient or uneven pickling, thereby affecting the quality of subsequent tanning and the performance of the finished leather.

[0004] Therefore, an acid pickling device for leather processing is proposed. Utility Model Content

The lifting assembly 200 includes a housing 201, which is fixedly installed on the top of the pickling tank 101. The left and right sides of the inner cavity of the housing 201 are movably connected to the first threaded rod 202 through a rotating shaft. The surface of the first threaded rod 202 is threadedly connected to the threaded sleeve 203. The inner side of the pickling tank 101 is equipped with a pickling tank mesh 204, and the left and right sides of the top of the pickling tank mesh 204 are fixedly connected to the threaded sleeve 203.
