Problems solved by technology

At present, the more common method is to use manual tensioning of the cloth, which brings a huge problem: operators, especially novice operators, are prone to prick their fingers by putting their hands under the needle, resulting in work-related injuries
[0005] However, since the operating experience during manual operation has an irreplaceable role in the work of the sewing machine, and directly determines the sewing effect of the obtained fabric, and the cost of the automatic cloth pressing device is relatively high, it is difficult to popularize, so the automatic pressing device is adopted. Cloth device is not enough to meet the needs of the existing technology

Abstract

The invention relates to the technical field of textile equipment, and discloses a sewing machine which comprises a sewing table, a sewing needle, a blocking plate and a support device. The sewing needle is arranged on the sewing table and can move in a reciprocating manner in the height direction to execute sewing work. The blocking plate is positioned on a side of the sewing needle and is connected with the sewing table by the support device. The sewing machine has the advantages that the blocking plate is arranged on the sewing table via the support device and can radially move along a tabletop of the sewing table, gaps are further reserved between the blocking plate and the sewing table, and to-be-sewn fabrics can pass the gaps; fingers of workers can be prevented from being injured by the sewing needle of the sewing machine when cloth piece goods are manually tensioned.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to a sewing machine. Background technique [0002] A sewing machine, also known as a tailor or sewing machine, is a machine used for textiles, which can sew textiles or other materials together with threads. Sewing machines have greatly improved the production efficiency of the textile and garment industry. At present, sewing machines are still one of the indispensable production equipment in the textile industry. [0003] When the sewing machine processes workpieces such as cloth, it needs to be processed after the cloth is tensioned to prevent the workpiece from being wrinkled and affecting product quality. At present, the more common method is to use manual tensioning of the cloth, which brings a huge problem: operators, especially novice operators, are prone to prick their fingers by putting their hands under the needle, resulting in work-related injuries. [0004] In the prio...
