An Axial Adjustment Mechanism of Plate Roller in Book Printing Machine

Abstract

The invention belongs to the technical field of printing machines for books and periodicals, and discloses an axial adjustment mechanism for printing plate rollers of a printing machine for books and periodicals. The printing plate roller axial adjustment mechanism of the book and periodical printing machine includes a transmission shaft, left and right wall panels distributed parallel to the left and right, and the corresponding positions on the left and right wall panels are respectively provided with installation holes and mounting holes. Hole 2, the two ends of the transmission shaft are respectively fixedly sleeved in the installation hole 1 and the installation hole 2 through installation bearings, and a version roller fine-tuning mechanism is installed on the transmission shaft. The axial adjustment mechanism of the printing plate roller of the book printing machine is a highly integrated adjustment mechanism of creative equipment, which is integrated with the plate roller to form an assembly, and the axial adjustment is realized internally. The direct adjustment of the transmission screw screw thread transmission greatly improves the adjustment accuracy and the equipment operation It is simple and convenient for maintenance, and the adjustment structure is less affected by the outside world, and can realize high-precision axial adjustment, which solves the problems raised in the background technology.

Description

technical field [0001] The invention relates to the technical field of book printing machines, in particular to an axial adjustment mechanism for printing plate rollers of a book printing machine. Background technique [0002] The axial fine adjustment of the version roller is required for the book printing machine to perform overprint printing. The axial movement method of the version roller in the axial adjustment mechanism of the existing book printing machine is that the version roller and the eccentric sleeve move axially along the jacket, and the adjustment error It is difficult to control, and the equipment is easy to run unstable. There are other improved methods. Chinese patent (CN 111186207A) discloses an axial adjustment mechanism for the plate roller of a book printing machine, including a plate roller. The left end of the plate roller passes through the left For the side wall board, the right end of the version roller passes through the right side wall board; th...

[0002] The axial fine adjustment of the version roller is required for the book printing machine to perform overprint printing. The axial movement method of the version roller in the axial adjustment mechanism of the existing book printing machine is that the version roller and the eccentric sleeve move axially along the jacket, and the adjustment error It is difficult to control, and the equipment is easy to run unstable. There are other improved methods. Chinese patent (CN 111186207A) discloses an axial adjustment mechanism for the plate roller of a book printing machine, including a plate roller. The left end of the plate roller passes through the left For the side wall board, the right end of the version roller passes through the right side wall board; the version roller corresponds to the inner hole of the left side wall board and the roller body in the inner hole of the right side wall board respectively installs bearings, wherein the inner hole of the left side wall board The left eccentric sleeve is supported on the bearing, and the axial limit of the left eccentric sleeve is set in the left wallboard... Although the eccentric sleeve has been improved, it still does not deviate from the traditional adjustment method, and the adjustment through gear transmission is also Difficult to ensure high precision
