Mechanism for achieving tight stitching and variable needle gauge reinforcement and achievement method thereof

Abstract

The invention relates to the technical field of stitching, in particular to a mechanism for achieving tight stitching and variable needle gauge reinforcement and an achievement method thereof. According to the method, micro needle gauge reinforcement can be achieved when stitching starts or ends, and it is prevented that a thread residue comes out of a stitching material after trimming, so that amark of reinforced stitching on the stitching material is shortened, a nest on the stitching material is prevented to a certain degree, tight stitching can be achieved, and accordingly convenience ofequipment operation and maintenance is improved. According to the technical scheme, an electromagnetic baffle is provided and connected with an installation supporting frame, a reset spring is arranged on a limiting pin in a sleeving mode, the limiting pin is arranged in a guiding hole of a limiting guiding block, an electromagnet is arranged on the rear end surface of the limiting guiding block,the limiting guiding block is arranged on the installation supporting frame through a side surface installation hole, a limiting sliding block is arranged in a top kidney-shaped hole in a limiting connecting rod, the limiting connecting rod is arranged on a needle gauge base through a top connecting hole, the lower end of the limiting connecting rod is connected with a back stitch connecting rod assembly, and the back stitch connecting rod assembly is connected with a back stitching electromagnet through a connecting hole in the lower end of the back stitch connecting rod assembly.

Description

technical field [0001] The invention relates to the field of sewing technology, in particular to a mechanism and a method for realizing tight seam and variable stitch pitch reinforcement. Background technique [0002] At present, the garment manufacturing industry uses a large number of sewing machines that can realize reinforcement seams and tight seams. It is a sewing equipment that completes a certain number of stitches at the beginning or end of sewing, and then performs normal sewing or stop sewing. This kind of equipment is reinforced. When sewing, the stitch length cannot be adjusted independently of the normal working stitch length, and the variable stitch length reinforcement cannot be realized. Normal sewing often uses a larger stitch length, which is easy to form a bird's nest on the back of the sewing material, and a longer and thicker line mark will be left on the sewing material after reinforcement stitching with a larger stitch length, which will affect the ap...

Problems solved by technology

[0002] At present, the garment manufacturing industry uses a large number of sewing machines that can realize reinforcement seams and tight seams. It is a sewing equipment that completes a certain number of stitches at the beginning or end of sewing, and then performs normal sewing or stop sewing. This kind of equipment is reinforced. When sewing, the stitch length cannot be adjusted independently of the normal working stitch length, neither can the variable stitch length be reinforced

Normal sewing often uses a larger stitch length, which is easy to form a bird's nest on the back of the sewing material, and a longer and thicker line mark will be left on the sewing material after reinforcement stitching with a larger stitch length, which will affect the appearance; The end of the thread is easy to come out from the sewing material behind the thread, especially when sewing soft and thick materials, the end of the thread is more likely to come out, causing the sewing product to be off-line to a certain extent, and affecting the quality of the product

Moreover, the tight seam mechanism and the reinforced seam mechanism of this sewing equipment are independent of each other, which makes the internal mechanism of the equipment complex and brings inconvenience to the operation and maintenance of the equipment.
