The present invention relates to a device for spiral S-type sock knitting machine to install a saw-type blade into the inside of the acupuncture to receive power from the camshaft to rotate the saw blade to cut the pattern yarn. Conventionally, as a device for cutting various pattern yarns, there is a single yarn device of a hosiery knitting machine, which uses a power source, Utilization Model Publication No. 79-5821, Name: Bell-drilled pattern and double-sided knitting. The heating wire and the suction pipe are installed, and the micro switch is installed in the chain and the drum cam of the van, and the micro switch operates automatically to supply the power when the socks and the back side yarn are to be cut during the knitting process. In order to supply power to the heating wire only when the knitting yarn rotated inside, the manufacturing process is complicated because the micro switch is installed in a complicated structure, and because the heating wire is installed inside the bed, the machine generates a lot of heat. Frequent breakdowns, especially the invasion of machines knitting children's socks Because it was a type, the single-pile of the heating wire could not be used, and there was a lot of difficulties in mass production because of the method of knitting the socks of the finished product and cutting them with scissors.

In the present invention, in view of the above points, the toothed disc blade is installed inside the needle so that it can be easily used even in a small knitting machine, and the power is transmitted from the cap shaft to cut the pattern yarn. The explanation is as follows.

On the upper side of the blade upper house (3) in which the blade fixing shaft (2) is integrally assembled, the brush house (5) in which the brush (4) is inserted is installed, and on one side, the upper knife holder (6) is installed and the upper knife (7) ) Is inserted into the sheath (8) was springed with a spring (9), the lower side is a locking projection 11 is protruding, the lower groove (15) is formed in the base of the blade (15) formed with a projection 12 in the center Installed the toothed disk blade 17 so that the locking groove 16 is inserted into the locking projection 11, and the blade rotating shaft 13 is screwed to the protrusion 12 as a nut 14, and the blade fixed shaft 2 Bevel gear 18 is attached on the upper side of the shaft groove 2 'in the shaft groove 2', and the nut 20 is inserted into the sock knitting machine needle 1 known as the holder 21. After installation, the shaft 31 is inwardly connected to the gear 31 of the camshaft 30 on one side of the knitting machine, and the gear 31 'on the lower side and the bevel gear 32 on the upper side are laid separately. Fixed holder (33) Chakseol to be the hayeoseo connected to the bevel gear 40, 41 and a Universal joint 44, 45, and the male and female connecting joint (42) (43).

The present invention having a structure as described above, the camshaft 30 continues to rotate when the sock knitting machine operates, and rotates the gears 31 and 31 'to rotate the shaft bar 32 and the bevel gears 41 and 32. When rotating in turn, the male and female joints 42 and 43 rotate the bevel gear 40 to rotate the bevel gear 18, so that the blade rotation shaft 13 is rotated, and the lower protrusion 50 of the blade rotation shaft 13 is rotated. ) Is hung on the hanging portion 51 of the blade bottom 15 and attached to the nut 14, and the locking protrusion 16 of the toothed disc blade 17 has a locking protrusion 11 of the blade bottom 15. Since it is fitted, the toothed disk blade 17 continues to rotate.

In this state, if the pattern yarn starts to skip during knitting, the pattern yarn is placed on the upper side of the serrated disc blade (17). 17 ') is rotated in a state sandwiched between, when the pattern yarn passes the position of the brush 5, the pattern yarn is naturally fitted to the lower side of the brush (4).

Then, when the sawtooth disk blade 17 continues to rotate and passes under the installed upper knife (7), the pattern is sandwiched between the upper knife (7) and the tooth (17 ') is cut.

At this time, since the upper knife 7 is supported by the spring 9, the patterned yarn is cut without mistakes because it always rotates in close contact with the teeth 17 'of the toothed upper blade 17.

Since the pattern yarn cut as described above is once rotated through the lower side of the brush 4, the brush 4 is momentarily pressed and the pattern yarn is not loosened, and the end of the pattern yarn cut at the upper knife 7 is brushed. Because it is sucked by a known blower (not shown) installed side by side with (5), the brush 4 and the blower are held in double, so the cut yarn is not loosened at all.

Then, when the pattern yarn is knitted again, the apostle supplying the pattern yarn descends and the pattern yarn is caught on the knitting needle inside the needle, and the knitting yarn is knitted. The teeth 17 'of the blade 17 are caught, and the above-described method is repeated to knit.

As described above, the present invention continuously rotates the toothed disc blade 17 to be connected with the upper knife 7, thereby cutting the pattern yarn, thus there is no malfunction, and a lot of heat is generated in the single yarn device using a conventional heating wire, thereby producing children's socks. Although it could not be used in a small knitting machine to knit, the present invention has a feature that can be used in any knitting machine because no heat is generated.

Claims (1)

As shown in the drawing, the upper knife 7 is inserted into the brush 5 and the upper knife holder 6 in which the brush 4 is inserted into the upper part of the blade upper part 3 in which the blade fixing shaft 2 is integrally formed. (8) is piled up with the spring (9), and the lower side sawtooth-shaped disk blade (17) is installed, and the projecting portion (12) is mounted with the blade cluster (15) on which the blade rotating shaft (13) is mounted as a nut (14). Attaching the bevel gear 18 to the upper side of the blade rotating shaft 13 and attaching the bevel gear 18 to the inside of the known needle 1 as the holder 21, and the bevel gears 40, 41 universal joints 44 and 45, And a pattern yarn cutting device of a spiral B-type hosiery knitting machine connected to the camshaft 30 by a male and female connection joint (42) (43).
