Problems solved by technology

[0005] In order to overcome the technical problems in the prior art that the parallelism of the stitches on both sides of the metal corns is poor, the stitch density is sparse and dense, the stitches are distorted, and the fabric is easily worn and the surface gloss of the metal corns is damaged. Provided is a guide assembly and an operation method for double-needle sewing machine quilting through metal corns. The guide assembly forms a covering around the metal corns, the feeding operation at the position of the metal corns is convenient, the consistency of the stitch distance is high, and the flatness of the stitches is good. In addition , the guide component protects the metal corns and the fabric, reduces the wear of the fabric and the damage to the surface gloss of the metal cornets, and effectively guarantees the quality of the product

Embodiment 1

[0035] Such as Figure 1 to Figure 3 As shown, a guide assembly includes a presser foot assembly and a guide member. The presser foot assembly includes a fixing part 1 and a stopper 2. One end of the stopper is rotatably connected with the stopper. The guide member is located at the other end of the stopper and Between the fabrics, the guide member is arranged along the threading direction of the sewing machine. The guide member is provided with several through holes 3 matching the metal eyelets; the fixing part includes a body 4 and a limit baffle 5, and the limit baffle is located on the body close to the fabric. One end of the body, the end of the body away from the limit baffle is provided with a rotating shaft 6, and the limit member is provided with a connecting ring that is sleeved with the rotating shaft; the limit member is L-shaped, and the limit member includes a connecting section 7 and a limit section 8, The connecting ring is located at the end of the connecting ...

Embodiment 2

[0046] In embodiment 1, the guide member is an integrated structure, and in this embodiment, the guide member is a combined structure, which can be adjusted according to the quilting requirements. Specifically, such as Figure 4 As shown, the guide member is spliced ​​by several guide sub-members 14, the right end of the left guide sub-member is provided with an insertion cavity 15, and the left end of the right guide sub-member is provided with a plug-in fitting that is mated with the insertion cavity. 17. The connection between the two guide sub-components is realized through the return spring 16, and each guide sub-component is provided with a via hole matching the metal eyelet.

[0047] In the actual processing and production process, the distance between two adjacent metal cornets may be different on different products. The guide component provided by this application is composed of several guide sub-components. When in use, the operator adjusts the distance between the ...

Abstract

In order to overcome the technical problems in the prior art that the parallelism of the stitches on both sides of the metal corns is poor, the stitch density is sparse and dense, the stitches are distorted, and the fabric is easily worn and the surface gloss of the metal corns is damaged. Provided is a guide assembly and a double-needle sewing machine quilting operation method for passing metal corns, including a presser foot assembly and a guide member, the presser foot assembly includes a fixing piece and a limiting piece, one end of the limiting piece is connected to the fixing piece in rotation, and the guiding piece Located between the other end of the limiting member and the fabric, the guide member is arranged along the threading direction of the sewing machine, and several through holes matching the metal corns are provided on the guide member. In this application, the guide assembly covers the periphery of the metal corns, the feeding operation at the position of the metal corns is convenient, the consistency of the stitch length is high, and the flatness of the stitches is good. The guide assembly protects the metal corns and the fabric, reducing the wear of the fabric and the metal. The damage to the surface gloss of corns is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of garment sewing, in particular to a guide assembly and an operation method for quilting threads of a double-needle sewing machine through metal eyelets. Background technique [0002] In the process of garment processing, it is often necessary to sew metal eyelets. For example, after the metal eyelets are punched on slacks, two lines must be quilted on both sides of the metal eyelets to form a limiting channel before the lace is threaded. At present, the common operation methods include the following two methods: 1. Use a lockstitch sewing machine to carry out threading operations twice to form a rope-threading channel after the corns are laid; 2. Use a double-needle sewing machine to quilting, and the limiting channel can be formed at one time. The problem is that when using a lockstitch sewing machine to perform the above-mentioned quilting process, it is necessary to complete the threading operation twic...
