Tension-free, dust-removing leather unwinding device

Abstract

A tension-free leather unwinding device with a dust removal function comprises a framework, a load bearing roller, a driving roller and a dust adhering roller. The load bearing roller, the driving roller and the dust adhering roller are arranged on the upper portion of the framework, the driving roller and the dust adhering roller are mounted in such a manner that the surface of the driving roller is tangent to the surface of the dust adhering roller, an upper leather detection probe and a lower leather detection probe are arranged on the outer side of the framework and are positioned on the lower portion of the driving roller, and shaft ends of the driving roller and shaft ends of the load bearing roller are respectively connected with driving mechanisms; an adjusting mechanism is further arranged on the lower portion of the framework and comprises a swing frame, a fixing roller and an adjusting roller, the fixing roller is mounted on the framework, the swing frame is sleeved on the fixing roller, the adjusting roller is mounted at the other end of the swing frame and can axially swing around the fixing roller along with the swing frame, and an upper adjusting roller detection probe and a lower adjusting roller detection probe are arranged on the framework and are positioned on a movement track of the adjusting roller; leather is mounted on the load bearing roller, is downwardly wound around the adjusting roller, then is bent upwards and penetrates a gap between the driving roller and the dust adhering roller. The tension-free leather unwinding device has the advantages that the leather can be automatically unwound in a tension-free manner, dust can be automatically removed when the leather is unwound, and a dust removal effect is good.

Description

technical field [0001] The invention relates to the technical field of leather inkjet printing, in particular to a tensionless and dust-removing leather unwinding device. Background technique [0002] In the prior art, when the leather is printed by inkjet printing, the unwinding of the leather is mainly controlled by manual unwinding. The leather cannot be under tension and must have no tension, which increases the difficulty of manual unwinding. At the same time, because the PU material leather contains powder and dust, dust should be removed before printing. The existing dust removal process is Relying on manual sticking of dust through the tape, the entire dust removal process is slow, tiring, and the dust removal effect is poor. Contents of the invention [0003] The object of the present invention is to provide a tension-free, dust-removing leather unwinding device in order to solve the above problems. [0004] The technical solution of the present invention is: a ...
