Description

Technical Field

[0001] The utility model specifically relates to the technical field of sewing machine feeding, in particular to a cuff and collar feeding mechanism for a sewing machine. Background Art

[0002] Sewing machines are widely used in the clothing, shoes and bags industries for sewing processing. Sewing machines are machines that can interweave or sew one or more layers of cloth, leather, etc. They are durable and have fast sewing speeds, which can improve the efficiency of sewing processing;

[0003] When sewing the cuffs and collars of the clothes we wear now, they need to be sewn on the move using sewing machines. However, traditional sewing machines usually use manual means to transport the fabric when sewing the cuffs and collars. During transportation, the high-speed sewing of the sewing machine may pose a certain threat to the hands of the staff, and when the fabric is transported manually, the position where the fabric needs to be sewn may be offset, which will result in the appearance of defective products and cannot effectively guarantee the sewing effect of the product. In addition, the traditional work efficiency of manual feeding is low.

[0004] After searching, Chinese patent publication number CN202222384929.1 discloses a sewing machine with a wrinkle-free feeding structure; comprising a base, the top of which is fixedly mounted a sewing machine body; a feed roller, arranged above the base, the upper surface of the base is fixedly connected to a fixing frame, the fixing frame is correspondingly arranged at the front and rear sides below the needle head of the sewing machine body, and the two ends of the feed roller are arranged inside the fixing frame; the right end of the feed roller passes through the fixing frame, and a small motor is arranged at the right end of the fixing frame, and both ends of the feed roller are fixedly connected to shaft rods, and the shaft rod at the right end is fixedly connected to the driving shaft of the small motor;

[0005] Although the structure in the above patent can achieve the effect of feeding when the sewing machine is sewing products, the height of the two feeding rollers set in the above patent is higher than the position of the sewing machine when sewing the product. Therefore, when the sewing machine is sewing, the product needs to be pressed down onto the work surface before sewing. In this way, during the feeding process of the feeding roller, the two products to be sewn will be offset, so that the effective sewing process of the product cannot be effectively achieved.

[0006] In view of the above situation, we provide a cuff and collar feeding mechanism for a sewing machine. In this device, a driving component and a conducting component are respectively arranged on both sides of the sewing machine body. The collar to be sewn is put on the rotating drum and the movable roller. After the putting is completed, the movable roller is driven by the cylinder to move, so that the two sides of the collar are flattened, and then the L-shaped connecting rod is driven downward by the electric push cylinder. At this time, the pressure wheel at the bottom of the slide rod is in contact with the product, and at the same time, the inclined surface on the matching block at the bottom of the L-shaped connecting rod is in contact with the inclined surface on the slide block, so that the movable drum slides along the rotating shaft. When the movable drum contacts the retaining ring, the internal support bar arranged inside the rotating drum can effectively support the product, and then the product is driven by the driving motor to effectively rotate, so as to achieve the effect of automatic feeding and greatly improve work efficiency.
