Longitudinal feeding structure of electronic pattern sewing machine

Abstract

The invention belongs to the sewing machine technology, in particular to the design of a vertical feed mechanism of an electronic pattern machine that a holding apparatus can be driven to move stably, which comprises a nose1, a motor 2, a synchronous motor drive belt 3, a synchronous pulley 4, a synchronous pulley shaft 5, a fixation apparatus 6, a feed drive synchronous pulley 7, a feed driven synchronous pulley 8, a feed synchronous belt 9, a feed driven synchronous belt shaft 10, a feed shaft and a synchronous belt clamping component 11, a feed shaft 12, a feed shaft fixation seat 13, a connection component 14 and a holding apparatus 15, and characterized in that the vertical feed power of the holding apparatus 13 of the electric pattern machine is provided from the motor 1 through twice transmission of the synchronous belt and can be controlled through the program. The vertical feed of the holding apparatus 15 is achieved through the pushing of the feed shaft 12 in fractional packed on the fixation seat 13 of feed shaft on both sides of the nose. The power of the feed shaft 12 is provided through the feed synchronous belt 9. The feed shaft 12 and the feed synchronous belt 9 are linked together through the feed shaft and the synchronous clamping component 11. The power of the motor 2 is connected through a synchronous structure, thus the vertical feed of the electric pattern machine is achieved.

Description

Technical field: [0001] The invention belongs to the sewing machine technology, and in particular designs a structure capable of stably driving the longitudinal feed of an electronic pattern machine. Background technique: [0002] Due to the development of the garment industry, the market's demand for patterns or patterns on clothing is becoming more and more extensive, which requires sewing machines that can quickly form patterns or patterns on clothing, which requires us to speed up the improvement of electronic pattern sewing machines. to increase efficiency. Electronic pattern sewing machine is a high-end type of sewing machine. It uses the vertical and horizontal feeding structure to drive the cloth pressing device of the machine, so as to drive the movement of the cloth, and then uses the stitch formation principle of the sewing machine to form various patterns on the cloth. the goal of. At present, the longitudinal mechanism of electronic pattern sewing machines is ...

AI Technical Summary

Problems solved by technology

At present, the longitudinal mechanism of electronic pattern sewing machines is generally driven by a single arm. Due to the instability of the single arm structure, it is easy to cause the cloth pressing device to tilt during the formation of the pattern or pattern, or the cloth pressing device on one side is not tight. As a result, the pattern or p
