Sewing machine capable of cleaning material flocks

Abstract

The invention discloses a sewing machine capable of cleaning material flocks. The sewing machine structurally comprises a machine head and a machine base, wherein the machine head is installed on the machine base; the machine head comprises a machine head body, a presser foot and a rotary valve; the presser foot is installed on the machine head body; the machine head body is provided with the rotary valve; the machine base is composed of a machine base body, a mounting and embedding plate, a machine side cover and a swinging shuttle structure; the machine base body is connected with the machine side cover in an assembled mode; the mounting and embedding plate is matched with the machine base body; the swinging shuttle structure is mounted on the machine base body and located below the presser foot; the swinging shuttle structure comprises a sweeping structure, a plate presser and a swinging shuttle; the sweeping structure is mounted at the bottom of the mounting and embedding plate; the plate presser is connected with the swinging shuttle; and the mounting and embedding plate comprises a plate opening. When the plate presser moves, an air conveying device conveys air upwards to prevent material flocks from entering from a gap between the plate presser and the mounting and embedding plate, the cleaning structure cleans the material flocks at the swinging shuttle in time through an air ejector and an air extractor, and it is guaranteed that all components keep flexibility and cannot be blocked by the accumulated material flocks.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to a sewing machine for cleaning wadding. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material; the sewing material is placed between the die and the presser foot, The movement of the sewing material is driven by the mop wheel. [0003] In the prior art, the die and the presser foot form a pair of pressure, and the moving sewing material will cause friction, and the wadding will be scraped off under the action of friction, and will enter from the gap where the thread cover and the die are spliced, and fall to the shuttle. The continuous transmission of material wadding is attached to each transmission part of the shuttle, which reduces the flexibility between the transmissions. If the cleaning is not timely, the accumulation of m...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art, and provide a sewing machine for cleaning the wadding, so as to solve the problem of the opposing pressure formed by the die and the presser foot, and the movement of the sewing material will cause friction, and the wadding will be scraped off under the action of friction. It will enter from the gap between the wire cover and the die, and fall to the shuttle. With the continuous transmission of the shuttle, the wadding will adhere to each transmission part of the shuttle, reducing the flexibility between transmissions. If it is not cleaned in time, it will cause The accumulation of flocs will also cause blockage and cause the problem of transmission jam
