Adsorbing fixed-type synchronous rotating auxiliary device for sewing round cut pieces

Abstract

The invention discloses an adsorbing fixed-type synchronous rotating auxiliary device for sewing round cut pieces. The auxiliary device comprises a control system, a transmission system and an adsorbing system. The control system is connected with the transmission system, the adsorbing system and a drive system of a sewing machine through a PLC. The transmission system comprises a stepping motor, a gear I, a gear II, a hollow shaft, a bearing, a bearing pedestal, a disc I and a disc II, wherein the gear I and the gear II are connected with the stepping motor, the hollow shaft penetrates through the center of the gear II, the bearing and the bearing pedestal are arranged in the middle of the hollow shaft and are parallel to the stepping motor, and the disc I and the disc II are arranged at the top of the hollow shaft. The round cut pieces manufactured by means of assistance of the auxiliary device are good in sewing quality, efficiency is high, two locating working procedures can be omitted, the total benefits can be increased by ten times or more, product uniformity can be ensured by operation of different personnel, and dependency on the technology of operators is reduced.

Description

technical field [0001] The invention relates to the fields of home textiles, shoes and hats, bags, and in particular to an adsorption-fixed synchronously rotating circular cutting piece sewing auxiliary device. Background technique [0002] At present, the sewing of round products in the home textile industry still adopts the traditional manual operation method. The traditional method requires high professional skills of sewing technicians. Even so, the roundness of sewing round products cannot be guaranteed. , when encountering the sewing of circular products with high requirements, there is nothing to do, so the uniformity and aesthetic requirements of the product cannot be guaranteed at all, and the size of the product sewed by the same person each time is different, so it is difficult to guarantee the same product. Uniformity requirements, quality is difficult to guarantee. [0003] It is more difficult and complicated to sew the body of the drum-shaped bag and the bott...

[0002] At present, the sewing of round products in the home textile industry still adopts the traditional manual operation method. The traditional method requires high professional skills of sewing technicians. Even so, the roundness of sewing round products cannot be guaranteed. , when encountering the sewing of circular products with high requirements, there is nothing to do, so the uniformity and aesthetic requirements of the product cannot be guaranteed at all, and the size of the product sewed by the same person each time is different, so it is difficult to guarantee the same product. Uniformity requirements, quality is difficult to guarantee

[0003] It is more difficult and complicated to sew the body of the drum-shaped bag and the bottom of the drum. Because the body of the drum-shaped bag and the bottom of the drum are of a three-dimensional structure, the common sewing method can only Sewing in small sections, and it cannot be guaranteed to be very smooth, especially when the bottom of the bucket is a two-layer structure of a round label and a layer of fabric, it is necessary to position and sew the two layers of round pieces with a lockstitch sewing machine first, and then put them together Position and sew together with the barrel body, and finally use the edge machine to sew the three layers together, the process is many, the speed is slow, and the quality is not easy to control

According to this common practice, each skilled operator can only do about 300 bucket bottom stitches per day on average, which is extremely low in efficiency and difficult to meet the needs of this product in today's society. Therefore, it is necessary to change the traditional operating process and study a New sewing method and auxiliary tools solve practical problems in this field
