Description

Technical Field

[0001] The utility model relates to the technical field of automated processing equipment, in particular to a lining feeding mechanism for adding lining during sewing. Background Art

[0002] Trouser loops are often used in the bottom of clothing, such as pants, skirts, etc., mainly for fixing belts. In order to improve the firmness of the trouser loop sewing and improve the grade of the product, a pad (also called pad cloth) will be added during sewing, and the pad, the body fabric and the trouser loops will be sewn together, thereby improving the firmness and durability of the trouser loops after sewing. Chinese patent document CN117265783A discloses an automatic pad cloth feeding device, in which the push plate driving device of the structure drives the push plate to move from left to right through the transmission rack, the transmission gear, the second synchronous belt assembly and the third synchronous belt assembly, thereby pushing the cut pad cloth to the bottom of the corresponding machine needle. Since the material is fed from under the presser foot (that is, the conventional material discharge direction, the left side of the needle), after the feeding is completed, the push plate needs to be reset, and the padding cloth is left under the needle and presser foot. Then the worker places the body fabric on the padding cloth of the sewing machine head, so that the padding cloth, body fabric and trouser loops are sewn together when sewing the trouser loops, which greatly improves the firmness of the sewing. This device greatly improves the automation of sewing pads and is highly efficient. However, when workers place the body fabric, it is easy to cause the padding to shift. Utility Model Content

[0003] The utility model aims to provide a lining feeding mechanism which has a simple structure and can accurately position the lining after feeding.

[0004] The basic technical scheme for achieving the purpose of the utility model is: a lining feeding mechanism, including a punching mechanism and a belt feeding mechanism. The punching mechanism is used to cut the lining belt into the corresponding shape of the padding cloth to be sewn. The belt feeding mechanism is used to convey the lining belt. Its structural characteristics are: it also includes a follower feeding mechanism. It includes a feeding plate, a feeding plate driving device and a follower mounting seat, and the feeding plate driving device drives the feeding plate to perform feeding positioning. The feeding plate driving device is arranged on the follower mounting seat. The follower mounting seat moves in a plane, which is conducive to improving the positioning accuracy during sewing.

[0005] Furthermore, in order to ensure smooth and rapid feeding and accurate positioning, the follow-up feeding mechanism also includes a feeding plate guide device. The feeding plate driving device drives the feeding plate to move left and right along the feeding plate guide device.

[0006] Furthermore, in order to ensure smooth conveying of the liner belt, the punching mechanism includes a feeding connection seat. The rear side of the feeding connection seat is provided with a belt threading hole running through the upper and lower parts thereof, which can limit the liner belt and prevent it from falling off.
