Line passing structure of needle bar rotating template machine

Technical Field

The utility model belongs to the technical field of make up equipment, a template machine is related to, especially a rotatory template machine's of needle bar cross line structure.

Background

When the template machine sews complex patterns, the situation of sewing towards any direction can be generated, the sewing quality towards different directions is different, and two stitch appearances of forward stitch and backward stitch can be generated. The backstitch stitch has poor appearance, the upper thread can be loosely twisted, the strength of the stitch is reduced, the breakage rate is improved, and the sewing quality is reduced. In order to solve the technical problem, a needle rod rotating template machine is produced, the upper thread of the needle rod rotating template machine penetrates through the inside of a needle rod, the needle rod can rotate infinitely for 360 degrees in the sewing process, the mutual position of a machine needle and the upper thread is always kept in a forward sewing state, therefore, backstitch stitches are avoided, the upper thread cannot wind the machine needle, the stitches are attractive, and the sewing quality is improved.

In the needle bar rotating template machine, since the upper thread passes through the inside of the needle bar, the inside of the needle bar needs to have a high degree of finish in order to prevent the upper thread from being scraped by the inside of the needle bar.

Chinese patent application (publication No. CN111020902A, publication No. 2020.04.17) discloses a needle bar rotating template machine, which comprises a needle bar, wherein one side of the needle bar is provided with an upper shaft, a thread picking assembly and a cloth pricking assembly, the thread picking assembly and the cloth pricking assembly are arranged on the upper shaft, and the upper shaft is driven by a first power piece to rotate and drive the thread picking assembly and the cloth pricking assembly to synchronously perform thread picking action and cloth pricking action. The needle bar of the scheme is long, an upper needle bar and a lower needle bar in the needle bar are formed by welding, the needle bar belongs to a long and thin workpiece, the smooth finish of the welding seam on the inner surface of the needle bar is difficult to process, the polishing method of the inner surface of the existing needle bar usually adopts an oil line polishing process manually, and although the process can achieve a good polishing effect, the problems of low production efficiency and high labor intensity are caused by purely manual single-piece production operation.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, the thread passing structure of the needle bar rotating template machine comprises a needle bar 1 and a thread passing sleeve 2 which are installed on a machine shell, wherein an inner hole 11 is formed inside the needle bar 1, a thread passing hole 21 is formed inside the thread passing sleeve 2, the peripheral side wall of the thread passing hole 21 is an inner surface which is easy to process smooth finish, and the lower end of the thread passing sleeve 2 is installed on the upper end of the needle bar 1 and the thread passing hole 21 is communicated with the inner hole 11. Preferably, the wire guide sleeve 2 in the embodiment is made of nylon or an integrally formed cold drawn light tube, so that the wire guide sleeve 2 made of the material can ensure that the inner surface of the wire guide hole 21 in the wire guide sleeve has enough smoothness, and is simple in processing process, high in production efficiency and suitable for mass production.

Preferably, the upper end of the wire guide sleeve 2 and the lower end of the wire guide sleeve 2 are of an integrated structure. The outer diameter of the upper end of the thread passing sleeve 2 is larger than that of the lower end of the thread passing sleeve 2, the outer diameter of the lower end of the thread passing sleeve 2 is smaller than the aperture of the inner hole 11 of the needle rod 1, and the lower end of the thread passing sleeve 2 is embedded in the inner hole 11 of the needle rod 1.

Because the outer diameter of the lower end of the thread passing sleeve 2 is smaller than the aperture of the inner hole 11 of the needle bar 1, when in work, after a surface thread enters the thread passing hole 21 of the thread passing sleeve 2, the surface thread directly enters the inner hole 11 of the needle bar 1 from the lower end of the thread passing hole 21 and then passes out from the lower orifice 12 of the inner hole 11 of the needle bar 1, and the middle juncture is not contacted with the inner hole wall of the needle bar 1 any more, thus the requirement on the smoothness of the inner hole wall of the needle bar 1 is reduced, and the polishing processing difficulty of the slender inner hole wall of the needle bar 1 is higher, therefore, the processing technology of the juncture is simplified. Furthermore, the utility model discloses well cross the internal surface of lateral wall all around of line hole 21 for easily processing the smooth finish, the optimal design that both combined together simplifies the processing technology to the smooth finish on the whole, reduces workman intensity of labour, promotes production efficiency.

The utility model discloses a set up and cross line cover 2, and cross the internal surface of lateral wall all around of the line hole 21 of crossing of line cover 2 inside for easily processing smooth finish to the artifical oil line that removes last needle bar from and lower needle bar welding seam department draws light technology, greatly shortens process time, promotes production efficiency. In addition, the threading mode can improve the smoothness of the upper thread when the upper thread passes through the inner surface of the needle bar 1, reduce the abrasion of the upper thread and further improve the sewing quality.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although the terms shank 1, bore 11, lower port 12, wire-passing sleeve 2, wire-passing bore 21, etc. are used more herein, the possibility of using other terms is not excluded.
