Description

Sewing machine with pushing mechanism

Technical Field

The utility model relates to the technical field of sewing machines, in particular to a sewing machine with a pushing mechanism.

Background

The sewing machine is an indispensable production tool in textile industry, and the sewing machine is changed from foot-operated driving to electric driving along with the development of the era.

According to the prior patent with the prior patent application number of CN201821137294.2, the sewn cloth is continuously moved to a direction far away from a sewing machine by means of the movement of the synchronous belt, so that the sewn cloth is prevented from being piled up, the occurrence of the phenomenon that the cloth is wrinkled is reduced, and the quality of a sewn product is improved.

However, this patent only considers that the cloth is piled up and wrinkles are generated, but does not consider that the wrinkles are generated at the sewing position in the sewing process, and as can be seen from the attached drawing of the specification of the patent, the pressing roller is only a round roller with smooth surface, and the pressing roller is lifted upwards by pressing the pressing rod in the working principle of the patent when the work is expressed, then the cloth after being sewn is placed under the pressing roller, the pressing rod is loosened, the pressing roller returns to the original position to press the cloth, and then the sewing work is performed, wherein the problem of flattening the cloth is not mentioned, and if the cloth is wrinkled in the sewing process, the wrinkles of the cloth are only more serious by adopting the pressing roller.

Meanwhile, materials of cloth encountered when the cloth is transversely stretched are different, tensile forces born by wefts of different cloths are also different, if all the cloth is stretched by one stretching device, the phenomenon of cloth tearing occurs if the cloth wefts bear weaker force and bear longer tensile force time.
