Wallboard of flexographic printing machine

Abstract

The invention discloses a wallboard of a flexographic printing machine, and belongs to the technical field of parts of printing equipment. The wallboard comprises a wallboard body, a positioning holeand a mounting groove, and further comprises a positioning block, wherein the mounting groove is formed in the bottom of the right side of the wallboard body, and the positioning block is used for being fixed to a chassis of the printing machine; a worm and gear mechanism is arranged in the mounting groove; a worm wheel is supported in the mounting groove in a rotating mode in the length directionof the wallboard body; the right end of a worm-wheel shaft extends out of the right side wall of the mounting groove; a worm meshes with the upper part of the worm wheel and is supported in the mounting groove in a rotating mode in the width direction of the wallboard body; the front end of the worm extends out of the front side wall of the mounting groove; the end part of the worm is fixedly connected to an adjusting handle; and the right end of the worm-wheel shaft is connected to the positioning block in a threaded mode. The wallboard of the flexographic printing machine can move slowly and stably to approach a farthest point position of flexible rotation of a positioning mandrel in the assembling process, the moving step pitch is extremely small, the precision is high, and therefore the farthest point error can be reduced, the assembling precision and the assembling quality can be improved, in addition, the operation is simple and labor-saving.

Description

technical field [0001] The invention relates to the technical field of printing equipment components, in particular to a wallboard for a flexographic printing machine. Background technique [0002] The wallboard of the printing machine is one of the main components of the flexographic printing machine. A large number of shaft and roller parts such as the printing plate cylinder, the impression cylinder, the paper transfer cylinder, and the positioning mandrel are installed between the two wallboards. The wallboard is the support. Its design, processing and assembly directly affect the accuracy and printing performance of the entire printing machine, and have a greater impact on the stability and reliability of the printing machine. [0003] In terms of wall panel assembly, the traditional assembly method is to use the positioning mandrel to assemble, specifically: use the plug to determine the position of the first wall panel on the chassis, and the positioning method for th...

Problems solved by technology

In order to further improve the assembly accuracy, when the wall panel moves close to the farthest point, the smaller the moving step, the better. In practice, the knocking method is generally used, but this method is not only time-consuming and laborious, but also difficult to control the moving distance. The farthest point is prone to error, which affects the assembly accuracy and assembly quality
