Auxiliary pressing foot of embroidery machine

Abstract

The invention discloses an auxiliary pressing foot of an embroidery machine. The auxiliary pressing foot is arranged on a needle bar frame, a plurality of needle bars are fixedly arranged on the needle bar frame, an air cylinder is fixedly arranged at one side of the needle bar frame, the auxiliary pressing foot is arranged the bottom of each of a first needle bar and a second needle bar close to the side of the needle bar frame, the auxiliary pressing foot is composed of a first pressing foot pipe, a second pressing foot pipe and a pressing block, the bottom of the first pressing foot pipe and the bottom of the second pressing foot pipe are fixedly connected with the pressing block respectively, the first pressing foot pipe is positioned right below the first needle bar, the top end of the first pressing foot pipe is connected with a piston rod of the air cylinder by a connecting rod, the second pressing foot pipe is located right below the second needle bar, an embroidery needle is arranged at the bottom of the second needle bar and is arranged in the second pressing foot pipe correspondingly. Compared with the prior art, the auxiliary pressing foot can press the cloth all the time during sewing, has large cloth-pressing area and effectively ensures the cloth to be in a flat state in a sewing range.

Description

Technical field: [0001] The invention belongs to embroidery machines, in particular to an auxiliary presser foot for embroidery machines. Background technique: [0002] With the continuous development of embroidery technology and the continuous improvement of production efficiency requirements, embroidery machines have gradually moved from a single embroidery function to a sewing machine function. For example, the production of down jacket compartments can be completed by embroidery machines, and its production Efficiency is higher than making by sewing machine. [0003] The current sewing machine has only one machine head, which needs to be operated by one person, and can only sew one piece of clothing at a time; while the embroidery machine has multiple heads, which only needs one person to operate, and can sew multiple pieces of clothing at a time. Therefore, the work efficiency is greatly improved and the production cost is saved, but a presser part like a sewing machin...
