Problems solved by technology

In the above-mentioned cloth feeding mechanism composed of the presser foot 5 and the cloth feeding dog 10, etc., when the sewing is in progress, the presser foot 5 is pressed on the cloth and does not move, and a frictional force is generated between the cloth and the cloth to hinder the movement of the cloth, and the cloth feeding dog 10 swings. Produces the frictional force that pulls the cloth forward. These two frictional forces have opposite effects on the movement of the cloth. For some smoother and thinner cloths, such as silk cloth, it is easy to make the cloth not move in time, resulting in wrinkling or tearing of the cloth. , resulting in reduced sewing quality or defective products

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention will be further described:

[0018] Such as Figure 2 to Figure 5 As shown, the synchronous belt feeding structure is installed on the sewing machine body 11, which is an improvement to the existing sewing machines, and the sewing machines include many kinds, such as common sewing machines, computerized lockstitch sewing machines and the like. Wherein, the motor support 13 is fixedly installed on the presser foot connecting rod 17 of the sewing machine, and can move up and down together with the presser foot connecting rod 17. The motor support 13 is equipped with a motor 26. The preferred stepping motor of the motor 26 can be controlled according to external pulse signals. action. The first synchronous pulley 12 is installed on the output shaft of the motor 26, and the outer edge of the first synchronous pulley has belt teeth for meshing with the internal teeth of the synchronous belt. The lower en...

Abstract

The invention provides a synchronous belt cloth feeding mechanism of a sewing machine. The cloth feeding mechanism is characterized in that an upper synchronous belt and a lower synchronous belt clamp cloth and feed cloth through synchronous movement. The synchronous belt cloth feeding mechanism enables various kinds of cloth to advance stably and smoothly, guarantees smooth progress of sewing and prevents damage and crumpling of cloth.

Description

Technical field [0001] The present invention involves a sewing machine sending mechanism. Specifically, it involves a synchronous band distribution mechanism that is combined with up and down bands used by a computer flat sewing machine. Background technique [0002] The basic structure of the existing sewing machine is attached figure 1 Show, at work, the pressing feet 5 on the pinnacle of the pinna 6 and the distribution of the cloth to the below will be tightly tightened by the two pieces of cloth that needs to be sutured.Press the foot 5 cooperate with each other to send away the sutured cloth, so that the suture continues.Among the above -mentioned delivery mechanisms composed of pressing feet 5 and delivery of cloth tooth 10, the pressing foot 5 presses on the cloth during the sewing, and the friction of the cloth to obstruct the cloth between the cloth will causeThe friction of driving the fabric is the opposite of these two frictions on the fabric movement. For some relat...
