Axial adjusting mechanism for printing plate roller of book and periodical printing machine

Abstract

The invention belongs to the technical field of book and periodical printing machines, and discloses an axial adjusting mechanism for a printing plate roller of a book and periodical printing machine. The axial adjusting mechanism for the printing plate roller of the book and periodical printing machine comprises a transmission shaft, a left wall plate and a right wall plate, wherein the left wall plate and the right wall plate are distributed in parallel left and right; a first mounting hole and a second mounting hole are formed in the corresponding positions of the left wall plate and the right wall plate correspondingly; the two ends of the transmission shaft are fixedly connected into the first mounting hole and the second mounting hole in a sleeved mode through mounting bearings correspondingly; and a printing roller fine adjustment mechanism is mounted on the transmission shaft. According to the axial adjusting mechanism for the printing plate roller of the book and periodical printing machine, the creative high-equipment-integration adjusting mechanism is integrated with the printing plate roller to form an assembly, axial adjustment is achieved inside, direct adjustment is achieved through thread transmission of a transmission screw, the adjusting precision is greatly improved, equipment operation is easy, maintenance is convenient, the adjusting structure is slightly influenced by the outside world, high-precision axial adjustment can be achieved, and the problems proposed in the background technology are solved.

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
