Rolling mechanism used for concave plate printing machine

Abstract

The invention relates to printing equipment, in particular to a rolling mechanism used for a concave plate printing machine. The rolling mechanism comprises a machine frame, a swing arm and a swing arm air cylinder, wherein the swing arm and the swing arm air cylinder are hinged to the machine frame. The swing arm air cylinder is located under the swing arm. A telescopic rod of the swing arm air cylinder is hinged to the swing arm. The end of the swing arm is provided with a square hole. A rectangular sliding block is installed in the square hole and provided with at least two side edges connected to the wall of the square hole through bolts. The end of a paper guide roller is inserted in the rectangular sliding block through a bearing. An air swelling shaft rolling mechanism body is arranged below the paper guide roller. According to the rolling mechanism, the paper guide roller capable of swinging is adopted for being matched with an air swelling shaft for rolling, the levelness of the paper guide roller can be adjusted finely, the structure is reasonable, use is convenient, and the rewinding quality is high.

Description

technical field [0001] The invention relates to a printing device, in particular to a winding mechanism for a gravure printing machine. Background technique [0002] At the end of the gravure printing machine, the winding mechanism undertakes the task of rewinding the printed paper onto the inflatable shaft. Since the paper is relatively fragile, the precision of the movement and the tightness must be controlled during the rewinding process. If the rewinding is too tight, it will easily break or tear the paper, and if it is too loose, it will affect the product quality. During the storage and transportation of the paper roll Creases are easy to appear. Some existing gravure printing machine rewinding mechanisms have too complex structures, high production costs, high failure rates, and difficult maintenance; some lack the precision of the action, and the rewinding is uneven. Contents of the invention [0003] To solve the above problems, the present invention provides a r...
