Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

It should be understood that the structures, proportions, sizes, and other elements shown in the drawings and described in the specification are included for illustrative purposes only and are not intended to limit the scope of the present invention. Any modification of structure, change of proportion or adjustment of size, without affecting the function and achievement of the purpose of the invention, should fall within the scope of the technical disclosure of the invention. In addition, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are used for clarity of description only, and are not used to limit the scope of the present invention, and changes or modifications of the relative relationship thereof may be regarded as the scope of the present invention without substantial technical changes.

In this application a cutter mechanism of duplex machine, cutter mechanism 100 includes aircraft nose 1 and locates the base 2 under the aircraft nose 1, and aircraft nose 1 extends to base 2 has the duplex 3 that is used for the sewing, and the rear side of duplex 3 is equipped with back cutter 4, and the bottom side of duplex 3 is equipped with presser foot 5, wherein: a front cutter 6 is adjustably arranged on the front side of the double needle 3; the double needles 3 can be inserted and sewn at the middle position of the presser foot 5; a winding drum 7 is fixed on the edge of the middle position of the presser foot 5; the automatic double-needle sewing machine has the advantages that the front cutter 6 is arranged at the position where the front side of the cloth strip enters at least, the cloth strip of wool is trimmed along the front side, the upper can 7 is arranged along the side position to arrange a cloth edge for wrapping, the attractiveness of cloth strip sewing is improved, and meanwhile the effect of the double-needle quick sewing efficiency is improved.

Referring to fig. 1 to 5, in the embodiment of the present application,

a cutter mechanism of a double-needle sewing machine is characterized in that the cutter mechanism 100 comprises a machine head 1, a base 2, double needles 3, a rear cutter 4, a presser foot 5 and a front cutter 6.

Wherein, the base 2 is fixedly arranged at the lower part of the machine head 1 of the sewing machine, the double needles 3 fixedly arranged in the machine head 1 are utilized to sew in the base 2, therefore, the double needles 3 used for sewing extend from the machine head 1 to the base 2, the presser foot 5 is fixedly arranged at the bottom side which is matched with the double needles 3 to work, and the sewing work is completed by matching the presser foot 5 with the double needles 3.

Wherein, the fabric burr is cut off by a rear cutter 4 arranged at the rear side of the double needle 3 in the sewing process, but the burr fabric is trimmed by a front cutter 6 at the front side of the double needle 3 at the front side edge of the presser foot 5, so that the front cutter 6 is adjustably arranged along the front side of the double needle 3; the regulation of preceding cutter 6 is adjusted from top to bottom, and to thick deckle edge cloth, the decurrent cutting edge of preceding cutter 6 is more, and then the decurrent cutting edge of preceding cutter 6 is less to thin deckle edge cloth. Wherein, in the combined use process, the double needles 3 are designed to be inserted and sewn at the middle position of the presser foot 5; the cooperation of the front and the rear cutters is ensured to be stable.

For further leveling and aesthetic adjustment of the raw edge fabric, a fabric strip for wrapping the raw edge is provided, and the fabric is supplied through a winding drum 7 for wrapping sewing combination, so that the winding drum 7 is fixed on the edge along the middle position of the presser foot 5.

In this application, for abundant assurance before cutter 6 and back cutter 4 can separate, guarantee the sewing of duplex 3 again simultaneously and before cutter 6 and back cutter 4 separately, consequently, set up presser foot 5 into the structure of rectangular shape, wherein, combining the leading-in and the derivation of cloth, consequently set up presser foot 5 and arrange along both sides ox direction promptly around, consequently, presser foot 5 extends along both sides around and is the ship shape.

In order to ensure that the cloth of the edge covering can be curled and folded, the upper barrel 7 is arranged to be of a horn-shaped cylinder structure, the cloth strip enters along the horn-shaped large opening of the upper barrel 7, and the cloth strip slides out along the horn-shaped small opening to form a folded shape.

Deckle edge cloth slides in under presser foot 5 along the fore-and-aft direction of preceding cutter 6 and back cutter 4 for the cloth strip of borduring gets into along the ship shape side along presser foot 5, consequently for avoiding mechanical interference, and the cloth strip forms the parcel along deckle edge cloth side, so the fixed setting on base 2 of setting of the ship shape side of a section of thick bamboo 7 along presser foot 5 of going up.

In the present application, as shown in fig. 3 and 4, in order to further fix the position of the front cutter 6, a Z-shaped front cutter holder 11 extends downward along the head 1, and the front cutter 6 is fixed by the Z-shaped front cutter holder 11. Therefore, the nose 1 has a front blade carrier 11 extending towards the front cutting blade 6.

In order to ensure that the corresponding front cutter 6 is adjustably fixed on the machine head 1, the front cutter 6 is fixed by using the front cutter frame 11, wherein the u-shaped cutter frame 61 is matched with the positioning pin 62 to form clamping fixation, and the u-shaped groove is utilized to ensure the up-and-down adjustment effect. Therefore, the bottom of the front cutter 6 is combined to form a blade, and the upper part of the front cutter is provided with a U-shaped cutter frame 61; a positioning pin 62 is fixed along the middle position of the cutter holder 61.

In order to further smoothly guide the cloth strip for edge covering, the cloth strip is leveled through the S-shaped cloth guide ring 8, and then the cloth strip is curled through the upper winding drum 7. Therefore, the upper sliver can 7 extends outwards to form an S-shaped cloth guide ring 8; the cloth guide ring 8 is provided with a cloth strip 9.
