Storage release type multi-functional winding drum preprinting device

Abstract

The invention belongs to the technical field of packaging mechanical equipment, and relates to a storage release type multi-functional winding drum preprinting device. The storage release type multi-functional winding drum preprinting device comprises a paper feeding guiding roller, a paper pressing roller and a paper discharging guiding roller which are rotatably arranged between two parallelly arranged wall boards, wherein the paper pressing roller is arranged between the paper feeding guiding roller and the paper discharging guiding roller; a rubber roller is tangentially arranged on the paper pressing roller in a rolling manner; a circle of wrapping lining is arranged on the surface of the rubber roller; rubber is arranged on the surface of the wrapping lining in a fitting manner; a printing surface is formed on the rubber surface; and the rubber has a printing trace original position and a printing trace tail end. According to the storage release type multi-functional winding drum preprinting device, storage release rollers are used for adjusting the paper operating state, so that the paper between the rubber roller and the paper pressing roller is enabled to be in a relatively static state during the color printing process, a neutral position part of the rubber roller can quickly rotate to the paper, intermittent printing patterns are guaranteed not formed on the paper surface, and the utilization rate of paper is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of packaging machinery and equipment, and relates to a storage-release multifunctional roll pre-printing device. Background technique [0002] In the field of packaging technology, printing color trademark patterns on cardboard is a common technical means, and the printing process is efficient and fast. It is no problem to realize the existing technology of color printing for some small packages, but for some large packaging products, the existing technology cannot realize better color printing, because there is no large printing machine to realize the corresponding printing operation; another The problem is that the quantity of large packages is limited, and the cost of plate making in the existing printing method is high. Generally, one roll and one color are used. When printing products of different sizes, the roll needs to be changed, which greatly increases the cost of the plate. Contents of the inven...
