Abstract

A no shuttle long position sartorius, have many sartorius heads 3 of synchronous operation of loom tacking head 1 and disembarkation head 2 drived by correspondence line shaft driving motor. The disembarkation head 2 of sartorius heads 3 have the crochet hook 4 which moves back and forth with sewing needle of loom tacking head 1 to realize make up. This invention can realize long time continuous work and advance the efficiency of equipment.

Description

A kind of no shuttle-type multi-head sewing device

Technical field

The present invention relates to multi-head sewing machine.

Background technology

In the prior art, a plurality of sewing machine heads of multi-head sewing equipment drive head and following head synchronous operation on it by corresponding line shaft, have improved operating efficiency than the single head Sewing machines.But the following head of the multi-head sewing machine of prior art all is to provide the bottom line of making usefulness with the shuttle tube, because the amount of this shuttle bottom line that tube is adorned is very limited, therefore be unsuitable for making continuously processing, often change bottom line shuttle tube and not only bother, also reduced the operating efficiency of sewing unit.

Summary of the invention

The technical problem to be solved in the present invention is, defective at the prior art existence, design no shuttle-type multi-head sewing device, it has cancelled the bottom line shuttle tube of traditional sewing device, can carry out making processing continuously or the sewings of big length being made processing continuously of long period, thereby improve the operating efficiency of multi-head sewing equipment greatly.

Technical solution of the present invention is, described no shuttle-type multi-head sewing device has the transmission mechanism by corresponding line shaft to drive a plurality of sewing machine heads of head and following head synchronous operation on it, its architectural feature is, the following head of described each sewing machine head is equipped with the crochet hook of doing corresponding reciprocal operation with last head sewing needle and realizing sewings is made.

Below make and further specifying.

Referring to Fig. 1, the present invention has by the last line shaft 14 of mutual synchronous operation, down line shaft 15 is with synchronously with 8, the 18 a plurality of sewing machine heads 3 that drive head 1 and following head 2 synchronous operations on it respectively, its architectural feature is (referring to Fig. 2 to Fig. 5), and the following head 2 of described each sewing machine head 3 is equipped with the crochet hook 4 of doing corresponding reciprocal operation with the sewing needle 5 of last head 1 and realizing sewing product is made.

Fig. 2 is a unit header structure schematic diagram of forming multi-head sewing equipment among a kind of embodiment of the present invention.Operation principle of the present invention as known in the figure: the corresponding site of following head 2 is equipped with crochet hook 4, the lower end of the swing arm 7 of this crochet hook 4 is fixed on the axle 9, the upper end of swing arm 7 is that front end is the curved boom 6 of prong shape, when Power Available Shaft 9 drives the reciprocally swinging that crochet hook 4 is made certain spoke degree, certain frequency, and when matching, just realized by the linear slit of sewings with the motion frequency of the sewing needle 5 that is installed with sewing thread.This sewing mechanism is subjected to no longer that limited amount bottom line limits in traditional bobbin thread for sewing machine shuttle tube, can make big length by sewings or carry out the long period make processing continuously.

As known from the above, the present invention is a kind of no rib formula multi-head sewing device (bull is meant the sewing machine head more than two or two), it has overcome the defective that traditional multi-head sewing machine is subjected to the restriction of shuttle tube base line length, that can do the long period makes operation continuously, has improved the operating efficiency of sewing device greatly.

The specific embodiment

Embodiment 1: as Fig. 1 and Fig. 2, or Fig. 6 and shown in Figure 2, following head 2 is equipped with crochet hook 4, swing arm 7 lower ends of this crochet hook 4 are fixed on the axle 9, and swing arm 7 upper ends are curved booms 6, and these curved boom 6 front ends are the prong shape, cooperate operation with the Sewing needles 5 that is installed with sewing thread, form the single-line type stitching; The driving mechanism of crochet hook 4, Sewing needles 5 can be implemented with reference to the closer of prior art.

Embodiment 2: as Fig. 1 and Fig. 3, or Fig. 6 and shown in Figure 3, curved boom 16 is grown than curved boom among the embodiment 16 and be which is provided with bottom line hole 11, cooperates operation to form the two-wire system stitching with the Sewing needles 5 that is installed with sewing thread; All the other structures are with embodiment 1.

Embodiment 3: as Fig. 1 and Fig. 4, or Fig. 6 and shown in Figure 4, head is provided with presser feet 12 and feeding tooth 13, and all the other structures are identical with embodiment 1.

Embodiment 4: as Fig. 1 and Fig. 5, or Fig. 6 and shown in Figure 5, head is provided with presser feet 12 and feeding tooth 13, and all the other structures are identical with embodiment 2.

Claims

1, a kind of no shuttle-type multi-head sewing device, there is transmission mechanism by corresponding line shaft to drive a plurality of sewing machine heads 3 of head 1 and following head 2 synchronous operations on it, it is characterized in that the following head 2 of described each sewing machine head 3 is equipped with the crochet hook 4 of doing corresponding reciprocal operation with the sewing needle 5 of last head 1 and realizing sewings is made.
