Novel small-head sewing machine

Abstract

The invention discloses a novel small-head sewing machine, which is characterized by comprising a machine shell; an installing wall and a worktable; a main pressing pin for pressing fabrics to be sewed, a delivering mechanism, a push mechanism, and a lifting mechanism are arranged on the installing wall; the delivering mechanism comprise a sewing needle, a needle driving part, a swaying pressing pin, and a swaying pressing rod; a supporting point and a driving point are arranged on the swaying pressing rod; a pusher and a shearing mechanism are installed in the worktable; the pusher comprises a material pushing driving part and a cloth delivering tooth in opposite to the swaying pressing foot; the pusher is applied to the driving point, thus the swaying pressing rod and the sewing needle are crossly and repeatedly swayed around the supporting point; the lifting mechanism applies force to the swaying pressing rod, and the shearing mechanism is used for shearing the sewing line crossed through the sewing needle. Through three-synchronous delivering mechanisms, the novel small-head sewing machine overcomes the shortcoming that the needle eye is easy to be pulled out of a long slot by the sewing needle during the working process of a traditional two-synchronous delivering sewing machine; the sewed line trace is beautiful, the sewing quality is greatly promoted; the overall structure is compact, and the movement stability is high.

Description

technical field [0001] The invention relates to the technical field of sewing equipment, in particular to a novel small-head sewing machine. Background technique [0002] A traditional sewing machine structure such as a Chinese utility model with a notification number of CN201952618U is a new type of small head sewing machine. Its main structure includes a machine head on which a driving part and a sewing needle are installed. Vertical up and down reciprocating movement, there is also a base plate under the machine head; the fabric to be sewn is placed between the machine head and the base plate, the sewing thread passes through the head of the sewing needle, and the sewing needle passes through the fabric reciprocatingly, and then the sewing is completed. Cloth sewing action. [0003] In addition, on the technical basis of the above-mentioned patents, there is also a relatively common two-synchronous composite feeding sewing machine. The operating relationship between the ...

AI Technical Summary

Problems solved by technology

[0004] But existing two synchronous composite feeding sewing machines are when sewing heavy materials, and the sewing needles will not completely break away from the sewing materials, and the feed dog and the presser feet will start to feed the materials. Therefore, the needle holes on the sewing materials will be pulled out by the sewing needles for a long time grooves, resulting in poor sewing quality
