Description

Technical Field

[0001] The invention belongs to the technical field of clothing sewing devices, and in particular relates to a cloth pressing device for a pocket pasting machine. Background Art

[0002] Automatic pocket sewing machines for clothing are also called pocket patching machines. They are widely used in the fields of clothing, home textiles, shoes and hats, bags and other industries. Especially in the fields of customization and fast fashion, the demand for sewing machines is more urgent. With the trend of industrialization, urbanization and consumption upgrading, the market demand for sewing machines continues to increase.

[0003] At present, in the sewing operation of clothing pockets, flat stitch sewing and bar tacking can be completed at one time, which is suitable for sewing various back pockets of jeans, shirt pockets, and other irregular shaped parts in clothing processing. When the feeding device of the pocket sticking machine folds the edge of the pocket cloth piece to be sewn and sends it to the clothes to be sewn, the clothes to be sewn need to be pressed and fixed, and the pocket cloth piece needs to be limited. Otherwise, during the sewing process, the sewing position and shape of the clothes are easy to change, causing skipping, broken thread, unqualified pocket sewing and other problems. The reference document CN211897339U discloses an automatic sewing device for clothing pockets, including a sewing device body, on which a pocket pressing plate and a fixing plate are arranged, the pocket pressing plate is composed of an inner plate and an outer ring, and the outer ring of the pocket pressing plate is provided with a first pressing plate and a second pressing plate, and a connecting piece is connected between the inner plate and the outer ring of the pocket pressing plate, the fixing plate is composed of an outer plate and an inner ring, and a connecting piece is also connected between the outer plate and the inner ring of the fixing plate, and the fixing plate, the first pressing plate and the second pressing plate are all provided with connecting blocks. The automatic sewing device for clothing pockets changes the size by adjusting the length of the pocket pressing plate and the fixing plate connecting piece, which is convenient for multiple uses of one plate, saves material resources and avoids waste. However, when this technical solution is used to sew pockets of different shapes, it is necessary to replace pressing plates of different shapes, and a whole pressing block template needs to be remade for each replacement of a pocket, which still wastes material resources. In addition, this technical solution only fixes the pockets to be sewn, but does not play a fixing role for the clothes to be sewn, and the equipment has poor versatility, which is not conducive to large-scale production.
