Abstract

The invention provides a drum which is simple in structure, convenient to process and improved in efficiency. The drum comprises a frame and a hollow drum body arranged on the frame. The hollow drum body comprises a barrel, and a first end cover and a second end cover which are arranged at two ends of the barrel. An inlet and an outlet are formed in the middle of the barrel. A first rotating shaft is arranged on the outer side of the first end cover. A second rotating shaft is arranged on the outer side of the second end cover. The first rotating shaft and the second rotating shaft are respectively arranged on the frame. Flexible components are respectively arranged at two ends of the opposite surfaces of the firs end cover and the second end cover. The inlet and the outlet are respectively formed between the flexible components at two ends. Each flexible component comprises a first sliding rod, a second sliding rod, a first sliding chute, a second sliding chute and a plurality of springs. Rows of stay bars are symmetrically arranged on two sides of the inner wall of the barrel respectively, and located at the outer sides of the first sliding rods, between the first sliding rods and the second sliding rods and at the outer sides of the second sliding rods. Lug bosses are arranged on the stay bars. Pressing blocks sleeve the stay bars. The moving efficiency of raw hides and the like in the hollow drum body is improved, and the novel drum is energy-saving and reliable.

Description

technical field [0001] The present invention relates to drums, in particular to drums for leather processing. Background technique [0002] In the prior art, during the tanning process, the raw hides are turned inside the drums (for example for washing, pickling, tanning, dyeing) or the hides are cleaned inside (by turning together with fine sawdust), and the drums are widely used in tanneries. The important equipment used is a wooden drum with convex piles or lifting boards inside. The leather can be operated in batches in the drum at the same time. When the motor is driven to rotate, the leather in the drum is subjected to mechanical action, which speeds up the reaction process and changes the physical properties of the leather. Performance, the application range of the drum covers most of the wet processing processes of tanning and dry softening, napping, etc. However, the existing leather has low activity efficiency in the drum and high working resistance, which is unfa...
