Efficient rotary screen printing machine and application thereof in polyester fabric printing process

Abstract

The invention discloses an efficient rotary screen printing machine and application thereof in a polyester fabric printing process, and relates to the field of printing equipment.The efficient rotary screen printing machine comprises a machine frame, the machine frame is provided with a printing platform, a rotary screen is installed on the printing platform in a rolling mode, the machine frame is provided with a scraper located in the rotary screen, the scraper is connected with a slurry conveying pipe, and the slurry conveying pipe is connected with the rotary screen. The rack is provided with a constant temperature mechanism acting on the rotary screen; the constant-temperature mechanism comprises a strip-shaped arc-shaped heat conduction plate which is mounted on the rack and covers the surface of the rotary screen, an S-shaped circulation channel which is formed in the arc-shaped heat conduction plate and is provided with an inlet and an outlet, and a first three-way valve mounted on the slurry conveying pipe; the first pipeline is connected with a branch opening of the first three-way valve and an inlet of the circulation channel, the second pipeline is connected with an outlet of the circulation channel and the scraper, and the other two branch openings of the first three-way valve are connected with the slurry conveying pipe and the scraper respectively. The printing device has the effect of being good in printing effect.

Description

technical field [0001] The application relates to the field of printing equipment, in particular to a high-efficiency rotary screen printing machine and its application in polyester fabric printing technology. Background technique [0002] The rotary screen printing machine is a kind of equipment for printing fabrics. Its principle is: the fabric is conveyed on a conveyor belt, and the conveyor belt is supported by a plane. The rotary screen is installed on the frame, and the rotary screen is pressed on the fabric. There is a scraper on the frame, and the scraper is coaxially set in the rotary screen. When in use, the color paste is added to the rotary screen through the slurry feeding pipe. The scraper presses the color paste out of the mesh of the rotary screen to adhere To the fabric to realize the printing process. [0003] When in use, the fluidity and adhesion of the color paste are greatly affected by the temperature, especially in winter when the temperature is low,...

AI Technical Summary

Problems solved by technology

[0003] When in use, the fluidity and adhesion of the color paste are greatly affected by the temperature, especially in winter when the temperature is low, the temperature of the color paste will drop due to the influence of the ambient temperature, and the color paste is generally heated in the color paste tank , maintain a certain temperature, but the temperature of the rotary screen will also change with the change of the ambient temperature, the temperature of the rotary screen will be transferred to the color paste, and when the color paste passes through the mesh of the rotary screen, it will also exchange heat with the color paste , resulting in a decrease in the temperature of the color paste and a reduction in the printing effect, thereby reducing the quality of the fabric
