Problems solved by technology
[0002] The axial movement mode 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. During the operation of the machine, the gap between the eccentric sleeve and the jacket will become larger and larger. At this time, the machine will produce a lot of noise and vibration
If the eccentric sleeve is not replaced in time, there will be unqualified products and may even damage other parts

The invention belongs to the technical field of packaging mechanical equipment, and relates to an axial adjusting mechanism of a printing roller of a book printer. The axial adjusting mechanism comprises a plate roller, wherein the left end of the plate roller penetrates through a left side wall plate, and the right end of the plate roller penetrates through a right side wall plate; bearings are respectively mounted on the roller bodies, corresponding to inner holes of the left side wall plate and the right side wall plate, of the plate roller, a left eccentric sleeve is arranged on the bearing in the inner hole of the left side wall plate in a supporting manner, and the left eccentric sleeve is axially arranged in the left side wall plate in a limiting manner; and a right blocking disc isarranged on the bearing in the inner hole of the right side wallboard in a supporting mode, the right blocking disc is sleeved with a right outer eccentric sleeve, the part, extending out of the right side wallboard, of the right outer eccentric sleeve is connected with a right inner eccentric sleeve in a matched mode, the right inner eccentric sleeve is limited on the right side wallboard through a right pressing plate, and the right outer eccentric sleeve and the right blocking disc are axially limited through a right baffle. According to the adjusting mechanism, accumulated errors generated by multi-part assembly are reduced, the adjusting precision is higher, and the implementation cost is lower.
Description
technical field [0001] The invention belongs to the technical field of packaging machinery and equipment, and relates to an axial adjustment mechanism of a printing plate roller of a book and periodical printing machine. Background technique [0002] The axial movement mode 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. During the operation of the machine, the gap between the eccentric sleeve and the jacket will become larger and larger. At this time, the machine will generate a lot of noise and vibration. If the eccentric sleeve is not replaced in time, unqualified products will appear, and other parts may even be damaged. Contents of the invention [0003] In view of the above problems, the present invention provides an axial adjustment mechanism for printing plate rollers of a book printing machine. The adjustment mechanism reduces the cumul...
