Abstract

The utility model relates to a reinforcing belt guiding structure of a four-needle six-line synchronous sewing machine, which improves the defects that a traditional machine trolley can not sew a netting twine when sewing two pieces of cloth, and thereby the bonding strength of the two pieces of cloth is not good. The utility model mainly relates to the four-needle six-line synchronous sewing machine, the synchronous sewing machine at least comprises a pressure foot with a needle hole and a knitting needle, wherein the knitting needle generates a reciprocating displacement stroke on the needle hole to carry out sewing operations, wherein a netting twine generating unit is arranged on the synchronous sewing machine, the netting twine generating unit is arranged near the needle hole and forms a reciprocating shaft rotating zone on the pressure foot to hook a weaving line to form the netting twine, the pressure foot is provided with a reinforcing belt approach road which is communicated with the needle hole under the reciprocating shaft rotating zone of the netting twine generating unit to contain a reinforcing belt, the reinforcing belt is weaved with the two pieces of clot synchronously under the condition that the netting twine generating unit movements are not affected, and the outer edge of the reinforcing belt forms the netting twine to increase the whole beauty and bonding strength.

Description

Four pins, six lines also stitch the reinforcing band guide structure of machine

Technical field

The relevant a kind of reinforcing band guide structure of the utility model system refers to a kind of reinforcing band guide structure that is applicable to four pins, six lines and stitches machine especially.

Background technology

General clothing is to piece together cloth joint institute by several piece to constitute, and see through Sewing machines and piece together the finished product of joint sewings of cloth with the formation clothing in those, for making the sewing joint of respectively piecing together cloth firm and stable, weave netting twine in the lump in the both sides up and down of piecing together the cloth joint when practice of industry lies in the sewing operation at present and reach netting twine down, or in joint outside while sewing one reinforcing band (as ribbon or elastic cord), to increase the bond strength of piecing together between cloth; And above-mentioned reinforcing band mainly be via a loudspeaker device (anchor clamps that shown in No. the 310732nd, TaiWan, China patent, are used for bound edge) with the inwardly stubborn folding in reinforcing band both sides attractive in appearance with the dimension clothing, afterwards, be arranged in the presser feet of Sewing machines again; Shown in " Fig. 1 and Fig. 2 ", it is the presser feet 100 that is used for the sewing reinforcing band in traditional Sewing machines, this presser feet 100 has a perforation 101 that supplies knitting needle to pass, and these perforation 101 the place aheads are provided with a bullport 102, reinforcing band 3 one ends system penetrates this bullport 102 and is positioned at the below of this perforation 101, when knitting needle when sewing is carried out in these perforation 101 reciprocal starts, this reinforcing band 3 can be sewed in the joint of piecing together cloth and form reinforcing effect, and its joint gets loose or produce the phenomenon in slit when preventing that clothing from being pullled.

Yet, when the consumer buys clothing, except the practicality that requires clothing, fastness, wear etc., the attractive in appearance of clothing also is the key factor that promotes desire to purchase, though on be set forth in the means of piecing together cloth joint sewing reinforcing band 3 and strengthened the bond strength that clothing is respectively pieced together cloth, but must modify the edge of reinforcing band 3 with loudspeaker device, not only improve the complexity of Sewing machines overall structure and sewing operation, and expose to the reinforcing band 3 no special modifications of piecing together cloth and form lofty contrast, cause consumer's purchase intention to lower with clothing; For modifying reinforcing band 3 to increase the aesthetic measure of clothing, the Sewing machines dealer proposes to go up the conception of netting twine sewing on reinforcing band 3, but there is not concrete implementer, the space that main system is subject on the presser feet 100 is limited, after in a single day bullport 102 on the presser feet 100 inserts reinforcing band 3, just not having the space that can utilize colludes for the start of netting twine generation unit and pulls out netting twine, and go out to go up netting twine if desire sewing, then can't insert reinforcing band 3, so the problem that reinforcing band 3 and last netting twine can't be implemented is simultaneously perplexed by the Sewing machines dealer for a long time always.

The utility model content
