Description

Technical Field

[0001] The present application relates to the field of overflow dyeing machines, and in particular to a cloth feeding device of an overflow dyeing machine. Background Art

[0002] Polyester, also known as polyester fiber, was invented in 1941 and is an important variety of synthetic fibers. Polyester is widely used in the manufacture of clothing fabrics and industrial products. Polyester has excellent shaping properties. The flat, fluffy shape or pleats of polyester yarn or fabric after shaping can remain unchanged after multiple washings during use. After the production of polyester fabrics, the fabrics need to be dyed by dyeing machines.

[0003] The Chinese patent with the authorization announcement number CN110656457A discloses a cloth dyeing machine, wherein a cleaning assembly is arranged on one side of the main body of the cloth dyeing machine, support frames are fixedly installed on both sides of the top surface of the bottom plate, suction holes are evenly opened on the sides of the hollow tube, a vacuum pump is fixedly installed on one side of the waste collection box, a leveling assembly is installed at the bottom end of the support frame, a resistance wire is fixedly installed inside the heating roller, a feeding roller is installed between two mounting plates, a gear box is fixedly installed on one side of the mounting plate, a motor is fixedly installed on one side of the gear box, and a motor is fixedly installed between the two support frames. A connecting plate is fixedly installed at the top of the hollow tube, and a soft brush is fixedly installed on one side of the connecting plate. When the cloth is fed in and passes through the hollow tube, the adsorbed impurities such as fluff, rags and dust are sucked into the hollow tube through the suction holes and then collected into the waste collecting box. The debris that is not removed is brushed off by the soft brush and then sucked in by the suction holes. The cleaning effect is good and does not affect the final dyeing effect. The feeding roller is driven by the motor to rotate and the cloth is fed in. During the feeding process, the feeding roller flattens the cloth, and the heating roller irons the wrinkles of the cloth to make the cloth smoother.

[0004] With regard to the above-mentioned related technologies, the soft brush is prone to be adhered with impurities or worn after long-term use, thereby reducing the cleaning effect of the soft brush on the fabric. The connecting plate is fixedly connected to the support frame, which is not convenient for replacing and cleaning the soft brush. Utility Model Content
