Wallboard of unit type photogravure press

Abstract

The invention discloses a wallboard of a unit type photogravure press. The wallboard of the unit type photogravure press comprises a bottom board, and a wallboard body which is fixed to the bottom board, wherein a rectangular vertical groove is formed in the middle of one side sruface of the wallboard body; a supporting plate is fixed to the bottom end of the vertical groovfe, and a lifting plateis arranged at the upper part of the supporting plate; a mounting hole is formed in one side surface, facing the outer side of the vertical groove, of the lifting plate; chutes are formed in the innerwalls of two sides of the vertical groove; the lifting plate is glidingly connected to the vertical groove through sliding blocks at two ends; an outer fixing pipe is mounted in the supporting plate;a lifting column is arranged in the outer fixing pipe; a vertical gear rack is arranged at one side of the lower end of the lifting column; and an opening is formed in the outer fixing pipe at the outer side of the gear rack. With the adoption of the wallboard of the unit type photogravure press, the accuracy in the roller mounting process is improved, and meanwhile, the abrasion of the roller inrotating to the mounting hole can be effectively reduced, so that the service life of the wallboard body can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of gravure printing machines, and in particular relates to a wallboard of a unit-type gravure printing machine. Background technique [0002] The wallboard of the printing machine is one of the main components of the unit-type gravure 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 starting point. The main basic parts for support and positioning, its design, processing and assembly directly affect the accuracy and printing performance of the entire printing machine, and will have a greater impact on the stability and reliability of the printing machine. [0003] After the wallboard of the existing printing machine is used for a long time, the hole of the wallboard will form an elliptical wear along the direction of its...

AI Technical Summary

Problems solved by technology

[0003] After the wallboard of the existing printing machine is used for a long time, the hole of the wallboard will form an elliptical wear along the direction of its force, and the gap between the roller shaft and the hole of the wallboard will expand, and the roller installed on the hole of the wallboard will vibrate greatly if the wear is serious , The cylinder is the heart of the printing machine, and the large vibration of the cylinder will inevitably lead to problems such as a decrease in printing plate durability and poor printing quality, and even affect the life of each functional part that completes the entire printing process
