Description

Dirt-resistant type automatic silk reeling machine silk guide drum Technical Field The utility model relates to the technical field of textile machinery, in particular to a dirt-resistant automatic silk reeling machine silk guide drum. Background During the reeling process, the raw silk needs to pass through a plurality of silk guide drums. The silk strip passes through the drum wheel which plays a role of guiding silk back and forth, and the reeling tension of the raw silk forming process is increased, so that the stretching performance of the raw silk is affected. In addition, the structural design of the existing drum has an antifouling defect, and after the drum housing and the drum core are assembled into a whole, the sericin pollution cannot be effectively prevented in the structural design, so that the normal operation of equipment is influenced. Reducing the resistance of the drum core to rotation during yarn guiding is a key point in reducing the silk reeling tension. The traditional drum core shaft is made of steel wires and is integrated with the drum core (see patent CN2185754Y, CN 2579915Y), the drum core shaft is supported and positioned by a drum, the drum support is fixed on a drum support, and as the drum support is formed by bending stainless steel, the two side surfaces of the support are not parallel, so that the drum support center is not in a straight line, the drum core shaft is influenced to flexibly rotate in the drum support, and the drum core is inconsistent in left and right positions relative to the drum support during installation, the actual use is influenced, and the quality of raw silk is seriously influenced. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide a dirt-resistant automatic silk reeling machine guide drum.
