Cloth stentering mechanism, cloth stentering method and cloth feeding device having stentering mechanism

Abstract

The invention relates to a cloth stentering mechanism, a cloth stentering method and a cloth feeding device having the stentering mechanism. The cloth stentering mechanism comprises a fixing board, a stentering roller hinged on the fixing board, and a compressing roller, a shelving roller and a guiding roller which are hinged on the fixing board and are parallel with the stentering roller, and a blowing tube connected on the fixing board, wherein pre-printing cloth is outputted from the cloth feeding mechanism and is wound around the stentering roller, the guiding roller, the shelving roller and the compressing roller sequentially, the cloth is tensioned through the stentering roller, the compressing roller, the shelving roller and the guiding roller, a guiding belt is at a lower portion of the compressing roller, a tail end of the cloth is compressed between the compressing roller and the guiding belt, an air inlet end of the blowing tube is connected with an air feeding device, and an air outlet end of the blowing tube is between the compressing roller and the guiding belt and faces towards one side of the fixing board. The cloth stentering mechanism can realize flattening of stentering crimping of the cloth especially a looped fabric and an elastic fabric, guarantees printing quality of the cloth, further guarantees no damage to a printing nozzle and can automatically correct a cloth conveying position according to a deflection condition of the cloth.

Description

[0001] technical field [0002] The invention relates to a cloth expanding mechanism used on a printing machine and a cloth feeding device with the expanding mechanism. [0003] Background technique [0004] When the cloth is printed, there is usually a phenomenon of curling during the feeding process, which affects the quality of the printed pattern of the cloth. At the same time, the curling part of the cloth will rub against the nozzle of the printing machine during the printing process, which not only affects the printing The effect, but also reduces the service life of the nozzle. [0005] In order to overcome the above-mentioned defects, in the feeding process of the cloth, it is usually necessary to carry out the expansion process. The existing method mainly uses the expansion roller to realize the expansion and tension of the cloth, but this method is not suitable for elastic cloth and knitted cloth. The expansion effect on both sides is not ideal, and there will s...

[0004] When the cloth is printed, there is usually a phenomenon of curling during the feeding process, which affects the quality of the printed pattern of the cloth. At the same time, the curling part of the cloth will rub against the nozzle of the printing machine during the printing process, which not only affects the printing The effect, but also reduces the service life of the nozzle

[0005] In order to overcome the above defects, in the feeding process of the cloth, it is usually necessary to carry out the expansion process. The existing method mainly uses the expansion roller to realize the expansion and tension of the cloth, but this method is not suitable for elastic cloth and knitted cloth. The expansion effect on both sides is not ideal, and there will still be curling
