Description

Chemical fiber fusion knotting machine {Chemical fiber fusion knotting machine}

The present invention relates to a chemical fiber yarn fusion knot machine, and more particularly, to a chemical fiber yarn fusion knot machine that fuses several chemical fiber yarns to form a knot.

In general, an air knot machine is used to connect yarn between bobbins with air knots for continuous production and complete exhaustion of yarn wound on bobbins in the process of yarn processing (twisting).

Conventionally, yarn and yarn were connected by hand knots, but in this case, a problem occurs in product quality due to a difference in thickness of the knot.

In Korean Patent Registration No. 10-1129484 (Patent Document 1), a compressed fluid is injected from an untwisting nozzle hole to untwist each of a plurality of double-ply twisted yarns to be threaded, and then a compressed fluid is discharged from the threaded nozzle hole. by spraying to give an impact to each other of the multiple strands of the twisted twisted yarn, and after untwisting each of the multiple strands of the twisted twisted yarn, by giving an impact by means of compressed fluid (air) between the multiple strands of the double stranded twisted yarn, A thread jointing device and a method for threading have been proposed in which the double-twisted yarns themselves are entangled with each other to complicate the entanglement of fibers protruding from each of the plurality of double-stranded twisted yarns.

Patent Document 1 uses high-pressure blown air to entangle the filaments forming the yarn so that they can be utilized as a knot.

However, when a knot is formed by the prior art using air, as shown in FIG. 10, a cutting length of about 2 to 7 mm occurs because the middle part is knotted with air and the thread at one end is cut, which is not necessary. Not only does it affect product quality, but the knotting machine itself is sold at a high price because it is composed of a very complex structure and many sophisticated parts, maintenance and management costs such as parts replacement and repair costs are high, and it is heavy, so it is difficult for the user's wrist. There are inconveniences such as giving a bunch to.

In order to improve this, the present inventor has applied for Korean Patent Registration No. 10-2067355 "Air knot machine".

On the other hand, the prior art degrades product quality due to the difference in thickness of the knot, and the structure is complicated, so parts replacement and repair costs increase, the price is expensive, and the weight is heavy, giving a burden to the user's wrist, and air hose It is inconvenient to work because it is connected, and energy loss is large because it uses pneumatic pressure, and it causes musculoskeletal disorders due to weight during continuous repetitive work.

It is composed by

Therefore, since the fixing stopper 500 is always in close contact with the side surface of the main body 100 by the elastic force of the spring 560, the thread is brought into close contact to exert a fixing force.

The operation of the present invention configured as described above is described as follows.

Insert the first thread (S1) into one side fixing stopper 500 to be inserted into the other side fixing stopper 500 through the knot forming part 200, and insert the second thread (S2) into the other side fixing stopper 500 to make a knot The first thread (S1) and the second thread (S2) are gathered together at the knot forming portion (200) by passing through the forming portion (200) and being inserted into the one-side fixing stopper (500).

Thereafter, after heating the hot plate 210, the heating tip 122, and the hot wire 123 for cutting, the upper body 120 is pressed downward so that the heating tip 122 is close to the hot plate 210 and the first The yarn S1 and the second yarn S2 are partially fused.

Thereafter, by operating the hot wire 123 for cutting, the remaining portions of each of the first thread S1 and the second thread S2 are cut off.

Accordingly, a knot T may be formed by fusing the first thread S1 and the second thread S2 with each other.

Although described in relation to preferred embodiments, it will be readily recognized by those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, and all such changes and modifications fall within the scope of the appended claims. is self-explanatory.
