Cloth edge moving positioning device and sewing machine

Abstract

The inventiondiscloses a cloth edge moving positioning device. After a cloth is conveyed to the designated position on a platen, a cloth pushing device drives the cloth to move towards a limiting assembly so that the cloth can enter a gap below a material limiting plate, the cloth pushing device stops motion till a sensor below the material limiting plate detects a cloth conveying signal, it indicates that the edge of the cloth has abutted against a baffle plate, the edge of the cloth is aligned, then, a pressing plate is moved downwards, the portion, namely the cloth edge where a slotted holeis located, of the cloth is pressed through the slotted hole in the limiting plate, then, a blowing device starts to blow air, the cloth outside a limiting assembly is blown to be flat to achieve thepurpose of removing cloth wrinkles, finally, the pressing plate of the pressing assembly is moved upwards, and then the cloth is pressed through the cloth pushing device, and the cloth is moved to asewing unit. Accordingly, the cloth edge moving positioning device can limit and guide the cloth, cloth wrinkles are removed, and the device is applicable to cloths of various sizes. The invention further discloses a sewing machine comprising the cloth edge moving positioning device.

Description

technical field [0001] The invention relates to the technical field of cloth processing, in particular to a cloth edge positioning device. In addition, the present invention also relates to a sewing machine comprising the above cloth edge positioning device. Background technique [0002] When sewing clothes with cloth, the cloth is usually placed on the platform, and the cutting and sewing of the cloth are usually controlled by both hands. The cloth has no positioning and it is difficult to make the cloth flat, and the quality of the sewn clothes is prone to quality problems. [0003] In order to solve the above-mentioned problems, a kind of cloth edge device has appeared. The current cloth edge device is near the sewing machine presser foot, and its main function is to limit and guide the cloth edge during the sewing process of the cloth. The edge-stop limit after the fabric is manually fed into the sewing machine has a narrow scope of application. [0004] The cloth edge...

Problems solved by technology

[0002] When sewing clothes with cloth, the cloth is usually placed on the platform, and the cutting and sewing of the cloth are usually controlled by both hands. The cloth has no positioning and it is difficult to make the cloth flat, and the quality of the sewn clothes is prone to quality problems

[0003] In order to solve the above-mentioned problems, a kind of cloth edge device has appeared. The current cloth edge device is near the sewing machine presser foot, and its main function is to limit and guide the cloth edge during the sewing process of the cloth. The edge limit is performed after the fabric is manually fed into the sewing machine, and the scope of application is narrow

[0004] There is also a cloth side-by-side device that adds a stopper on the table, and aligns the cloth side-by-side through the stopper, but this device cannot solve the problem of wrinkles after the big cloth is side-by-side
