Description

Technical Field

[0001] The utility model relates to a fabric joint mechanism, in particular to an up and down telescopic fabric joint mechanism. Background Art

[0002] In the textile printing and dyeing industry, the sewing of fabrics is usually achieved by manually coordinating the functions of different workstations. For example, most factories manually sew two pieces of fabric with a sewing machine to connect the ends, and then carry out subsequent printing, dyeing and shaping processes.

[0003] When manual coordination is adopted, first, the head and tail of the fabric need to be aligned manually, and then the sewing machine is operated to sew. The joint efficiency is very low. If the connection is not neat when the head and tail of the fabric are aligned manually, it will cause subsequent work to be carried out unsmoothly, such as skew weft of printing, unstable operation of cloth on the roller, etc. In addition, equipment with different functions of different workstations, such as the sewing machines required in the process, will take up space, which leads to the obstruction of the transfer of fabrics of the whole vehicle, which invisibly hinders the normal production efficiency.
