AI Technical Summary

Technical Problem

In existing gravure printing equipment ovens, the height of the blower nozzles is fixed, making it difficult to adjust according to printing materials of different thicknesses, resulting in poor drying effect and affecting printing quality.

Method used

An adjustment device was designed, including components such as a hydraulic cylinder, a dovetail slide rail, a slide block, and an external threaded tube. The hydraulic cylinder drives the third support plate to rise and fall, thereby adjusting the height of the blower nozzle. Combined with a manual adjustment mechanism, the height of the blower nozzle can be flexibly adjusted.

Benefits of technology

It enables the adjustment of the blower nozzle height according to printing materials of different thicknesses, improving the drying effect, meeting diverse production needs, and ensuring printing quality.

Abstract

This application provides an adjustment device for a gravure printing oven, relating to the field of oven adjustment technology. It includes an adjustment mechanism mounted on the top plate of the oven, a second support plate on the adjustment mechanism, a hydraulic cylinder on the top of the second support plate, a second connecting plate connected to the piston rod of the hydraulic cylinder, a third support plate on the side of the second connecting plate, a dovetail slide rail mounted on one side of the third support plate, several sliding seats on the outer surface of the dovetail slide rail, and dovetail grooves on the side of the sliding seats near the third support plate that slidably connect with the dovetail slide rail. An externally threaded tube is mounted on the sliding seat, and the bottom end of the externally threaded tube is connected to an air nozzle. This application utilizes the hydraulic cylinder to drive the third support plate to rise and fall via the second connecting plate. During the rising and falling of the third support plate, the dovetail slide rail, sliding seats, and externally threaded tube drive the air nozzle to move up and down, thereby adjusting the height of the air nozzle. This adjustment device can adjust the height of the air nozzle according to the thickness of the printing material.
