Description

A water-based paint rotary screen printing device

Technical Field

The utility model relates to the technical field of rotary screen printing, in particular to a water-based paint rotary screen printing device.

Background Art

Rotary screen printing machine is also called rotary screen printing machine. It can be divided into three types according to the arrangement of the rotary screen: vertical, horizontal and radial. The most commonly used is the horizontal rotary screen printing machine. The rotary screen printing machine is used in combination with other units. It has the advantages of high production efficiency of the drum printing machine and the characteristics of the flat screen printing machine that can print large patterns and rich colors. It is recognized as a printing machine between drum printing and flat screen printing and has a major breakthrough in printing technology.

During use, the rotary screen printing machine needs to convey the printed fabric to the lower end of the rotary screen roller through the fabric guide belt, print it through the rotary screen roller, and then dry the fabric of the printed structure through the drying equipment. At this time, the fabric guide belt will bypass from the lower end and continue to circulate. Few existing devices have the ability to clean the fabric guide belt. The surface and bottom of the fabric guide belt are easily contaminated with oil or dye during use. If it is not cleaned in time, pollutants will enter the device or contaminate the fabric. A few rotary screen printing machines with cleaning devices can only clean one side of the fabric guide belt. The cleaning degree is insufficient and the cleaning roller cannot be kept continuously moist. At the same time, the tightness adjustment structure of the fabric guide belt of the existing rotary screen printing machine is mostly complicated. Therefore, we need to upgrade and transform it based on the existing technology.
