Description

The multi-purpose sewing machine that uses different layouts and needle tracking to make fabric

Technical field

The present invention relates to a kind of Sewing machines, industrial type especially is designed for and uses dissimilar needle trackings and regulate needle tracking and arrange the machinery make the Sewing machines of two fabrics.

Background technology

Therefore, it is a kind of Sewing machines with characteristics, because the quick setting of described device can be made two fabrics by at least two kinds of dissimilar needle trackings with the required separation distance layout.

As everyone knows, with two or multi-disc weave machine the Sewing machines that is sewed together usually with industrial standard according to designing based on being designed for the different structure characteristic of carrying out distinct program.

For example, known Sewing machines is to have the single needle that is used for sewing clothing or the device of spininess, and for example, described clothes are common jeans or casual pants, Work Clothes, shirt or other clothes.

Prevailing form is, these dissimilar Sewing machiness have the top head at a suture needle place, the mechanism that supply multi-disc fabric is used to sew and the matrix that is arranged on head bottom, top, and it comprises the device that helps to form needle tracking with suture needle.

Be transformed into reciprocating motion by the rotatablely moving of shaft-driven top head that is connected in CD-ROM drive motor by cam, pass to the suture needle bracing or strutting arrangement then.In close suture needle position, the top head also carries a presser feet, and the function of this presser feet is that the fabric that keeps multi-disc to be made presses down towards the bottom matrix.

The fabric feed mechanism generally includes the specific device that acts on the fabric of being made, and this device makes described fabric move along a direction.

The matrix that is positioned at head bottom, top comprises the crochet hook that at least one uses with suture needle, to finish needle tracking.

Naturally, all can be carried out rotation and realize these actions in a synchronous manner with the parts in preceding description that laterally move.

When design and producing Sewing machines, processed needle tracking type is even more important.

Clearly, therefore parts that the dissimilar needs of each of needle tracking are different and need them to carry out different motions need use different Sewing machiness for different needle trackings.

For example, the known technology that is used to process the eliminant needle tracking need have the crochet hook of specific continuous rotation and the Sewing machines with synchronism, the transverse movement of the suture needle of the twice 360 degree rotations that described synchronism need be equivalent to be produced by described crochet hook.

On the other hand, the processing chain stitch needs such Sewing machines, and it has the crochet hook that is different from eliminant needle tracking shape, has reciprocal rotation and/or transverse movement, and has and need the Sewing machines of suture needle with respect to the synchronism of the transverse movement of crochet hook motion.

In addition, this needs that reciprocating motion passed to described crochet hook are forced the manufacturer to make to have in fact be different from the Sewing machines that those are designed for the structure of making the eliminant needle tracking.

Another difference between this Sewing machines of two types is, comprises having the coil that is inserted into the line in the crochet hook, the different institutions that is used to make the Sewing machines needs of chain stitch even can be positioned over machine exterior though make the Sewing machines of eliminant needle tracking.

Difference important and essence between two kinds of dissimilar machines is the shape between eliminant needle tracking and the chain stitch and the greatest differences of structure.

Therefore, according to known technology, two kinds of dissimilar Sewing machiness must be corresponding to two kinds of dissimilar needle trackings.

For the company and the client that need to provide flexible further and multiduty service (mainly being the quick variation of style) in textile industry, this has comprised a sizable expense.

Summary of the invention

That the objective of the invention is to overcome above all and mentioned and because the other problems that single Sewing machines produces, this single Sewing machines can be alternately or is made eliminant needle tracking and/or double-chain needle tracking in combination.

According to the present invention, these purposes and advantage realize by a matrix that is used to comprise the Sewing machines of head, described matrix comprises at least one presser feet and at least one suture needle, described matrix is characterised in that it comprises that at least one comprises the transmission mechanism of at least one second crochet hook by first crochet hook that driver part drives with at least one; Described transmission mechanism is designed for by being connected in the drive unit that is included in the parts in the matrix and provides rotation for described second crochet hook; Described transmission mechanism moves with respect to described matrix by driving and regulator.

The Sewing machines that comprises the matrix of design like this advantageously allows to use single structure to make two kinds of dissimilar needle trackings, and in single structure, different parts can be according to needed dissimilar needle tracking work.

Therefore the objective of the invention is no longer to need to buy two kinds of different machines, thereby saved great amount of cost.In addition, because the Sewing machines of being discussed, the relative arrangement of determining the sewing needle tracking by means of a quick and simple initialization system is possible: in fact, according to machine operation person's needs by expect the change of bore (caliber) can metering needle and pin between distance.
