A drying room of a rotary screen printing machine

Abstract

The invention discloses a drying room of a circular screen printer. The drying room of the circular screen printer comprises draught fans, heat sources, a conduction band, a conduction band roller, cloth press rollers, an air outlet and a baffle, wherein the area of the drying room is divided into an upper area, a middle area and a lower area by fabric and the baffle; the drought fans are of three different types, the number of the drought fan of the largest type is three, and the drought fans of the largest type have an air blowing function and are located in the area formed by the fabric and the upper portion of the drying room, the number of the drought fans of the middle type is three, the drought fans of the middle type have an air suction function and are located in the area formed by the baffle and the lower portion of the drying room, the number of the drought fans of the smallest type is two, and the drought fans of the smallest type have the air suction function and are located in the area formed by the baffle and the fabric; the number of the heat sources is three, the heat sources are fixedly hung on the room top of the drying room through small metal bars, and the positions of the heat sources correspond to three air blowers; the combination body of the conduction band and the conduction band roller is arranged in an inclined direction and forms a 30-degree angle with the horizontal plane, the number of the cloth press rollers is three, and the cloth press rollers are located on the downstream in the running direction of the fabric; the baffle is connected with the front face and the back face of the drying room, and gaps are formed between the baffle and the left face and the right face of the drying room; and the air outlet is communicated with an fabric outlet.

Description

[0001] Technical field: [0002] The invention relates to the technical field of rotary screen printing machines, and more specifically relates to a drying chamber of a rotary screen printing machine. [0003] Background technique: [0004] The drying room is the drying equipment of the rotary screen printing machine. After 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. The final product requires the color paste to be embedded in the surface of the fabric in a solid state. This requires the drying room to quickly solidify the color paste by means of high temperature and high pressure. Temperature control is the most important for the drying function of the drying room. The temperature should not be too high or too low. If it is too high, it will easily brighten the color of the printing and dyeing, while the low temperature may not completely solidify the color paste. The existing d...

Problems solved by technology

Temperature control is the most important for the drying function of the drying room. The temperature should not be too high or too low. If it is too high, it will easily brighten the color of the printing and dyeing, while the low temperature may not completely solidify the color paste.

The existing drying technology is to place the drying guide belt of the printing machine flat, provide a heat source in the drying room and use a fan to diffuse the hot air to various positions in the room. The original purpose is to make the temperature of the surface of the fabric run reach an ideal temperature. stable temperature, but often only unidirectionally blows air into the drying room, and ignores the drying room formed by the fabric and the upper half, and the drying room formed by the fabric and the lower part has formed its own air circulation model, and the result is easy to cause The temperature field on the surface of the fabric is disordered, and the drying degree of the color paste is not good, which is not conducive to the production and processing of high-quality products and affects economic benefits
