Abstract

The invention provides a printing and dyeing mechanism elevating device of a flat screen printing machine that can quickly respond to changes in the load of the printing and dyeing mechanism. It is characterized in that it includes a lifting mechanism part for lifting and lowering the printing and dyeing mechanism and its driving source, and a power auxiliary mechanism for assisting the driving force of the driving source for raising the printing and dyeing mechanism; the power auxiliary mechanism is composed of a cylinder with the following mechanism: Mechanism composition: a cylinder, a piston rod, and two air chambers inside the cylinder that are divided by the piston area. The air supply mechanism makes the two air chambers generate a pressure difference and adjusts the pressure adjustment mechanism for the pressure difference; The pressing force of the piston rod generated by the pressure difference acts on the lifting mechanism to generate auxiliary power.

Description

technical field [0001] The invention relates to the lifting device of the printing and dyeing mechanism of an automatic plane screen printing machine which is equipped with one or more printing and dyeing mechanisms and performs single-color or double-color printing and dyeing on the printed matter sent in a certain amount. Background technique [0002] This printing and dyeing mechanism lifting device also has such a device: the compression spring assembled under the printing and dyeing mechanism is used as an auxiliary power mechanism. The rebound force of the spring makes it function as an auxiliary power. [0003] However, the above-mentioned compression springs have the following problems: due to the constraints of the installation space, it is difficult to obtain the expected rebound force, especially, the difference in the rebound force between the lower limit position and the upper limit position is large, and in the case of load fluctuations, It is necessary to cha...
