Description

Technical Field

[0001] This utility model belongs to the field of printing press technology, specifically relating to a packaging printing rewinding and anti-wrinkle mechanism. Background Technology

[0002] When printing continuously to form a product, the printed product is often wound into a roll by a winding mechanism to facilitate transportation and subsequent handling.

[0003] Chinese patent application number 202421108055.X discloses a packaging printing winding anti-wrinkle mechanism, including a base frame on which a primary support roller group, a secondary support roller group, and a winding roller are arranged; and an anti-wrinkle component, which includes a rotating frame rotatably disposed between the secondary support roller group and the winding roller, a tensioning wheel rotatably disposed at the first end of the rotating frame, a pressure wheel rotatably disposed at the second end of the rotating frame, and elastic elements disposed at both ends of the rotating frame. The packaging printing winding anti-wrinkle mechanism provided by this utility model utilizes the rotation of the rotating frame of the anti-wrinkle component by the elastic elements, so that the tensioning wheel is located below the horizontal direction of the secondary support roller group to tension the printed product, while the pressure wheel, by contacting the printed product and applying downward pressure, flattens the printed product about to be wound, thereby further ensuring the flatness of the printed product during the winding process and avoiding the problem of wrinkles caused by loosening of the printed product during the transport process, which would damage the pattern on the product during subsequent winding.

[0004] The aforementioned patent has the following drawbacks in use: it cannot iron out wrinkled printed products, resulting in poor anti-wrinkle effect; at the same time, the rewind roller is difficult to disassemble and assemble, causing inconvenience in use. Utility Model Content
