Automatic cloth guide device for intelligent sewing machine and working method of automatic cloth guide device

Abstract

The invention discloses an automatic cloth guide device for an intelligent sewing machine. The automatic cloth guide device for the intelligent sewing machine comprises a telescopic cloth guide workbench, a support, a cloth guide roller, a roller mounting frame, a first motor, a roller lifting mechanism, a roller height fine adjustment mechanism and presser feet, wherein the support is vertically mounted above the telescopic cloth guide workbench; the roller lifting mechanism is mounted on the support through the roller height fine adjustment mechanism; the roller mounting frame is connected with the roller lifting mechanism; the cloth guide roller is mounted on the inner side of the roller mounting frame; the first motor is mounted on the outer side of the roller mounting frame; an output shaft of the first motor is connected with a driving shaft of the cloth guide roller; and the pressing feet are mounted on the two sides of the roller mounting frame through adjustable connecting arms. Cloth guide is achieved through rotation of the cloth guide roller arranged above an operation table, and in the cloth guide process, the presser feet press cloth located on the front side and the rear side of the cloth guide roller, so that the cloth is prevented from being wound up, and it is guaranteed that the cloth is conveyed flatly; and the cloth guide roller can be finely adjusted according to the thickness of the to-be-processed cloth, so that the situation that the cloth guide efficiency of the cloth is affected due to the fact that the cloth guide roller and the cloth are pressed too tightly or too loosely is avoided.

Description

technical field [0001] The invention relates to the technical field of sewing machines, more specifically, the invention relates to an automatic cloth guiding device for an intelligent sewing machine and a working method thereof. 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 material. The sewing function can sew fabrics such as cotton, hemp, silk, wool, and artificial fibers, and products such as leather, plastic, and paper. The stitches are neat and beautiful, smooth and firm, and the sewing speed is fast and easy to use. [0003] When the sewing machine is working, the teeth under the presser foot cooperate with the presser foot to realize the cloth feeding. At present, the cloth feeding method has the problem of difficulty in feeding the cloth, and the cloth is prone to pile up during the forward process, making the sewin...

Problems solved by technology

[0003] When the sewing machine is working, the teeth under the presser foot cooperate with the presser foot to realize the cloth feeding. At present, the cloth feeding method has the problem of difficulty in feeding the cloth, and the cloth is prone to pile up during the forward process, making the sewing uneven; During the sewing process, due to the limited size of the existing sewing machine operating platform, the cloth is not laid flat on the sewing machine operating table, which affects the normal cloth guiding of the cloth
