Detecting unit for detecting fabric sewing quality

Abstract

The invention relates to a detecting unit for detecting the fabric sewing quality. The detecting unit is located at a detecting station of a worktable, and the detecting station is located in front ofthe cloth feeding direction of a sewing station; the detecting unit comprises a second cloth feeding actuator and a cloth feeding detecting mechanism, wherein the cloth feeding detecting mechanism islocated on the second cloth feeding actuator; the second cloth feeding actuator comprises a second cloth feeding roller shaft and support frame structures symmetrically disposed on two sides of the second cloth feeding roller shaft; the second cloth feeding roller shaft can be lifted relative to the worktable under the action of the support frame structures. The detecting unit has the benefits that the detecting unit has the functions of detecting and cloth feeding, and no additional detecting station is required to be arranged, thereby saving the space cost; the detecting unit is automatically adjusted by a controller, and no manual operation is required, thereby saving the labor cost.

Description

technical field [0001] The invention belongs to the technical field of sewing equipment, and in particular relates to a detection unit for fabric sewing quality detection. Background technique [0002] In the process of using a sewing machine, when two pieces of patterned fabrics are sewn, in order to ensure the appearance of the finished product, it is generally necessary to align the patterns of the two pieces of fabrics before sewing. The process of aligning the patterns in the prior art mainly relies on Manual operation is labor-intensive, and depending on the experience of the operator, the accuracy of the pattern produced varies, resulting in defects in the final product. [0003] In addition, during the sewing process, the sewing machine occasionally has the problem of sewing skipped threads, especially when two pieces of fabric are butt-stitched, the problem of sewing skipped threads is prone to occur. In the prior art, the detection of this skipped thread problem ma...

[0002] In the process of using a sewing machine, when two pieces of patterned fabrics are sewn, in order to ensure the appearance of the finished product, it is generally necessary to align the patterns of the two pieces of fabrics before sewing. The process of aligning the patterns in the prior art mainly relies on Manual operation is labor-intensive, and depending on the experience of the operator, the accuracy of the pattern is different, resulting in defects in the final product

[0003] In addition, during the sewing process, the sewing machine occasionally has the problem of sewing skipped threads, especially when two pieces of fabric are butt-stitched, it is prone to the problem of sewing skipped threads. In the prior art, the detection of this skipped thread problem mainly relies on manual detection. It is labor-intensive to complete, and once there is an omission in the inspection, it will cause defects in the finished product
