Description

Repeated overedger serging machine

Technical Field

The invention belongs to the technical field of sewing equipment, and relates to a repeated overlock machine.

Background

When the overedger needs double-pass overedged overlocking for some materials during sewing, the conventional overedger sewing method is to carry out secondary overedged overlocking on the materials, so that an operator needs to spend double the time to complete the process, the time is greatly wasted, and the production efficiency is reduced. For sewing requiring a copying process, the needle pitch of the overedger is adjusted to be minimum by the conventional overedger, so that the speed of the overedger is reduced to be minimum, and the production yield is influenced.

Disclosure of Invention

In view of the above, the technical problem of the prior art is to provide a overedger capable of performing repeated overedged overlocking at one time, which is used for improving the yield and reducing the production cost in the production process.

The invention is realized by the following technical scheme. A repetitive overlock sewing machine mainly comprises: the needle clip 1 is provided with at least two or more needle containing holes, the arrangement direction of the needle containing holes is consistent with the feeding direction of the overedger, and the arrangement direction of the machine needles 2 is consistent with the feeding direction of the overedger; the needle plate 4 is provided with at least two thread-discharging tongues 9, and the arrangement direction of the thread-discharging tongues 9 is consistent with the feeding direction of the overedger; the pressing foot 3 is provided with at least two pressing fingers 11, and the arrangement direction of the pressing fingers 11 is consistent with the feeding direction of the overedger; the upper curved needle seat 8 is provided with at least two upper curved needles 7, and the arrangement direction of the upper curved needles 7 is consistent with the feeding direction of the overedger; the lower curved needle seat 6 is provided with at least two lower curved needles 5, and the arrangement direction of the lower curved needles 5 is consistent with the feeding direction of the overedger.

The number of the machine needle 2, the upper bending needle 7, the lower bending needle 5, the thread discharging tongue 9 and the pressing finger 11 of the repeated overedger overlock overedger is two (or more than two).

In the overlock overedger, the needle clamp 1 is provided with at least two or more needle holding holes, the arrangement direction of the needle holding holes is consistent with the feeding direction of the overlock overedger, and the arrangement direction of the machine needles 2 is consistent with the feeding direction of the overedger.

In the repeated overedger overlock overedger, the arrangement direction of the thread-feeding tongues 9 on the needle plate 4 is consistent with the feeding direction of the overedger.

In the above repeated overedger serging and overlocking machine, the arrangement direction of the pressing fingers 11 on the pressing foot 3 is consistent with the feeding direction of the overedger.

In the above repeated overedger overlock overedger, the upper curved needle seat 8 is provided with at least two upper curved needles 7.

In the above repeated overedger serging and overlocking machine, the arrangement direction of the upper curved needles 8 is consistent with the feeding direction of the overedger.

In the repeated overedger overlock overedger, the lower curved needle seat 6 is provided with at least two lower curved needles 5.

In the above repeated overedger serging and overlocking machine, the arrangement direction of the lower curved needles 5 is consistent with the feeding direction of the overedger.

Detailed Description

Embodiment 1. the technology of the invention forms a multi-needle set mechanism on an overlock machine, under the transmission of each part of the overlock machine, a machine needle 2, an upper curved needle 7 and a lower curved needle 5 are tightly matched to form a plurality of wire plaits and discharge the wire plaits on a corresponding wire discharge tongue 9 on a needle plate 4; the wire braid formed by the first sleeve needle is discharged out from the first wire discharging tongue 9 on the needle plate 4; the strand formed by the second trocar is wrapped in the discharged strand, and the discharged strand is discharged from a second thread discharging tongue 9 on the needle plate 4; after being discharged, the thread braid formed by the third trocar is wrapped inside and discharged at the third thread discharging tongue on the needle plate 4. And by analogy, the stitches of each set of needle are repeatedly sewn on the same stitch.

Example 2. the present invention is designed such that when the stitch length of the overedger stitch is adjusted to two thirds of the distance between the two sewing needles 2 of the overedger, the stitch length of the sewn stitch is doubled.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by one skilled in the art without departing from the spirit and scope of the invention; the technical scope of the present invention is not limited to the contents of the specification, and must be determined according to the scope of the claims.
