Automatic overturning device of hosiery machine

Abstract

The invention relates to the technical field of hosiery machines, in particular to an automatic overturning device of the hosiery machine. The automatic overturning device of the hosiery machine comprises a cylindrical needle barrel mechanism and a wind suction pipe communicated with a sock outlet pipe, a base plate is arranged under the needle barrel mechanism, the needle barrel mechanism and the base plate are respectively connected with the main body of the hosiery machine, an outer horn-shaped pipe with a large upper opening and a small lower opening is arranged in the needle barrel mechanism, an inner horn-shaped pipe matched with the outer horn-shaped pipe is arranged in the outer horn-shaped pipe, the wind suction pipe movably penetrates through the small opening of the lower end of the outer horn-shaped pipe, the upper end of the wind suction pipe is in abutting connection with a small opening of the lower end of the inner horn-shaped pipe, a plurality of ventilation ports are formed in the lateral wall of the inner horn-shaped pipe, a lifting mechanism is arranged on the base plate, and the wind suction pipe is connected with the lifting mechanism and moves vertically along with the lifting mechanism. According to the automatic overturning device of the hosiery machine, through a wind suction pipe opening with the two horn openings, a wind suction effect is generated between the inner horn opening and the outer horn opening to clamp fabric, the inner horn opening sucks wind to pull the fabric and enables the fabric to be overturned inwards, the reverse surface of the woven fabric is outwards, the procedure of manual surface overturning is omitted, production efficiency is improved, and production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of hosiery knitting machines, in particular to an automatic turning device for hosiery knitting machines. Background technique [0002] The computer hosiery machine generally adopts the weft weaving method. The circular needle cylinder of the loom is equipped with 100-600 needles. The needle cylinder runs clockwise at high speed to catch the warp and move up and down to complete the tuck and unloop. The old coil must be withdrawn from the needle latch during one cycle, so it is necessary to apply a pulling force to the withdrawn coil. The needle cylinder of the current sock knitting machine is equipped with a suction pipe, and the port of the suction pipe is facing the sock that has been drawn out of the needle cylinder, and generates a pull-down traction force on it, and the semi-finished socks after knitting are exited from the sock opening drop. [0003] After knitting the socks, the toe of the sock nee...

Problems solved by technology

However, the front of the semi-finished socks knitted by the sock knitting machine is on the outside, and the socks need to be turned over when sewing the head, which often takes up a lot of time for workers, reduces production efficiency, and makes it difficult for enterprises to recruit workers and increase production costs.
