Description

Cloth drying device of circular screen printer

Technical Field

The invention belongs to the technical field of textile machinery, and particularly relates to a cloth drying device of a circular screen printer.

Background

The drying room is drying equipment of the rotary screen printing machine, when the fabric is printed and dyed by the rotary screen, the color paste on the fabric is still in a liquid or partially liquid-solid mixed state, and the final product requires the color paste to be embedded into the surface of the fabric in a solid state, so that the color paste needs to be rapidly solidified by the drying room in a high-temperature and high-pressure mode. The temperature control is most important for the drying function of the drying room, the temperature cannot be too high or too low, the printed and dyed colors are easy to brighten when the temperature is too high, and the color paste can not be completely solidified when the temperature is low.

The drying device of the existing rotary screen printing machine is used for horizontally arranging the fabric, providing a heat source in a drying room and using a fan to diffuse hot air to each indoor position, and the device neglects an air circulation model of a fabric drying environment, so that the temperature field on the surface of the fabric is disordered, and the drying degree of color paste is poor. Meanwhile, the printing speed of the rotary screen printing machine is 1.5-3 times faster than that of the flat screen printing machine, so a drying room must be lengthened to ensure that the fabric has enough time for drying, but the drying room is too long, occupies a large space, and has low utilization rate, so that improvement is needed.
