Multi-needle fine-adjustment computerized sewing machine

Abstract

The invention provides a multi-needle fine-adjustment computerized sewing machine. A main drive shaft is connected with a main drive gear, a carrier shaft, a carrier gear, a gear pin, a needle bearing and a synchronous gear are arranged in a needle box, the synchronous gear, a left eccentric wheel and an eccentric wheel rack are respectively mounted on the gear pin, a synchronous moving pin is mounted in an air cylinder at the bottom of the needle box, retractable rods are respectively connected with movable blocks, roller pins and slide ways, the bottoms of both ends of the slide ways are provided with racks which are engaged with shuttle groove gears, the shuttle groove gears are mounted at both ends of shuttle groove drive shafts, a lower shifting fork is fixed at the bottom of a rotating shuttle slide way, the rotating shuttle slide way is mounted upon a rotating shuttle slide way-fixing rod, the rotating shuttle slide way-fixing rod is mounted under a frame, and an eccentric wheel gear-restoring spring is mounted on an internal eccentric wheel gear. The multi-needle fine-adjustment computerized sewing machine can set different programs according to requirements for different styles of quilting stitches producing cotton-padded clothes in order to meet requirements for different specifications of quilting stitches, and can carry out the process of making quilting stitches of cotton-padded clothes done by eight to ten sewers.

Description

technical field [0001] The invention relates to the field of sewing equipment, in particular to a multi-needle fine-tuning computerized sewing machine. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. The stitches are neat, beautiful, flat and firm. Fast sewing and easy to use. Most of the industrial sewing machines are general-purpose sewing machines, including lockstitch sewing machines, chain sewing machines, quilting machines, overlock sewing machines and interlock sewing machines, etc. Among them, the utilization rate of lockstitch sewing machines is the highest.

AI Technical Summary

Problems solved by technology

[0003] At present, the purchase quantity of sewing equipment and the leased area of ​​the workshop cannot be effectively controlled. Once the expected number of workers cannot be reached, the excess equipment and workshop area will increase the operational risk of the enterprise in disguise. In today's society, it is difficult to employ workers and the mobility of workers In the context of the general situation, the "labor shortage" has had a huge impact on sewing companies. Today's job seekers not only have requirements for salary and benefits, but also need room for advancement, a good working environment, living environment, and sufficient rest time. At present, the sewing equipment adopts the workflow of one person, one machine, and fixed procedures. High-quality products need to be processed. For example, when processing plain or twill cotton clothes, when the single-needle machine sews cotton clothes with multiple stitches, only Can sew one stitch, and the distance between the needle bars of the multi-needle quilting machine is fixed, and the width of the quilted cotton cannot be adjusted appropriately according to the style of the cotton-padded clothes. Especially when sewing irregular lines, the sewing efficiency is low and the quality is low. There is no guarantee, and ordinary workers cannot work on the machine, so that the workers cannot be flexibly transferred. Once the production volume increases, the work cannot be delivered within the contract period, which will cause great losses to the enterprise. Thread setting different programs, sewing equipment that can meet the requirements of different specifications
