[0002] At present, in the production process of mattresses, spring assembly is mostly required. During the operation, it is necessary to first fold the non-woven fabric into a bag, and then insert a row of springs from the folded opening of the non-woven fabric. After the springs are compressed by tools, a sewing machine is used to sew between the two springs to separate and position each spring; in addition to separating and arranging adjacent springs, it is also necessary to sew the folded opening of the non-woven fabric to ensure that the springs will not leak out, and finally the springs are moved to a horizontal position. The traditional assembly method is manual operation, which requires the cooperation of multiple people. The operation is cumbersome and inefficient, and the consistency of the stitching position is poor, the spring position is unevenly arranged, and the overall assembly effect is poor, which ultimately affects the quality of mattress production. Therefore, a cloth bag sewing and assembly spring device is designed to solve the above problems.
