AI Technical Summary
Traditional leather dyeing equipment suffers from heavy metal pollution, poses health risks due to the use of bisphenol retanning agents, and has poor dyeing effects and low efficiency. Furthermore, traditional agitators cause serious damage to the leather.
The dyeing drum uses a rotating drum with a turning component on the inner wall. The turning component includes a turning plate and a turning rod. By rotating, the leather is subjected to alternating high and low intensity beatings. Combined with the adjustable length of the turning rod, the dyeing effect is improved and the damage to the leather is reduced.
It improves the dyeing effect of leather, reduces leather damage, expands the scope of application, and achieves efficient and clean dyeing.
