Description

Technical Field

[0001] The utility model relates to the field of leather pattern forming, in particular to a pressing component suitable for leather pattern equipment. Background Art

[0002] The processing of leather patterns is usually carried out by pressing out leather molds and then shaping at high temperature. The equipment used in this processing method is relatively simple, but there are also problems. During the extrusion process, the thickness of the leather becomes thinner, and after the density increases, the feel is relatively hard, which is significantly worse than the soft feel before processing the pattern. In order to solve this technical problem, it is necessary to form the pattern through negative pressure high temperature shaping. However, during the high temperature shaping process, the leather will shrink, and it is necessary to prevent the leather from shrinking during the transmission process. Therefore, the transmission mechanism needs to realize both the transmission function and the tensioning function. The prior art also provides a transmission mechanism that can simultaneously realize the transmission function and the tensioning function. The transmission mechanism includes a transmission assembly, a tensioning assembly arranged on the transmission assembly, and a clamping assembly for cooperating with the tensioning assembly. However, the pressure wheel and the pressure wheel shaft of the existing clamping assembly are basically rigidly connected in position and cannot be disassembled, which is not conducive to later maintenance.
