Description

Retraction assembly for printing coiled material Technical Field The utility model relates to the technical field of printing coiled material winding and unwinding, in particular to a winding and unwinding assembly for printing coiled materials. Background In the printing process of a printer, materials are usually wound and unwound into rolls in a mechanical mode by using a winding and unwinding machine, and the winding and unwinding machine is widely applied to paper rolls, cloth rolls, plastic rolls and metal coil processing production lines, and is designed and diversified according to actual process requirements, and the specification types of the winding and unwinding machine are also more and more diversified and flexible to apply. CN218201581U discloses a winding and unwinding device for printing coiled material by using flat-panel ink-jet, in which, in the process of winding, the coiled material is split by a cutter frame on the splitting device through the splitting device, so as to be split into multiple coils, then, when passing through the pressing roller device, the reducing motor device drives the pressing roller to rotate, the pressing roller flattens the split coiled material, avoiding the phenomenon of bending the edge of the split coiled material, and at the same time, two dust removing rollers remove dust from the outside of the coiled material, improving the cleanliness of the coiled material, but the winding and unwinding device for printing coiled material by using flat-panel ink-jet is not convenient for realizing tensioning adjustment of the coiled material, which is easy to cause loosening or overtightening phenomenon of the coiled material, thereby damaging the coiled material or affecting the subsequent normal use. Disclosure of Invention The utility model aims to solve the technical problem of providing a winding and unwinding assembly for printing coiled materials, which can effectively solve the problems that in the prior art, although the winding and unwinding assembly can play a role in cutting and the like, in the using process, the tensioning adjustment of the coiled materials is inconvenient to realize, the coiled materials are easy to loose or overtightening, and the coiled materials are damaged or the follow-up normal use is influenced.
