Abstract

The utility model relates to a round tail flat needle seat for a flax weaving machine, belonging to the special purpose machine of the flax weaving machine, composed of a needle holder body and two rows of round tail flat needles. The needle tails of the round tail flat needles form cylindrical shapes, the needle bodies form flat cones, and the two rows of flat needles are longitudinally arranged in a flat plane. The utility model overcomes the defect that existing round needles are easy to bend and fold. The utility model has the advantages of long service life, shorter stop time for maintenance and low labor intensity. Because the flat needles are longitudinal arranged, the staple slivers are even, the drawing effect is good, and the product quality is raised.

Description

Round tail flat needle seat for flax weaving machine

The utility model relates to the linen textile industry, is the equipment special that is used for the flax roving machine.

China's linen textile industry is generally used the Speed frames that the Soviet Union, Italy make at present, all adopts the round needle needle stand on these type of Speed frames, because system pin technology is difficult to ensure the quenching hardness requirement, so round needle is easily curved easy to break.In the board running, the stifled pin phenomenon that bent needle takes place often and cause inadequately because of hardness, so that board shuts down frequently, maintenance time is long, influence board operating efficiency and waste serious, clean shortcomings such as difficult, that labor strength is big.

Shortcomings such as the purpose of this utility model provides the flat pin needle stand of a kind of flax roving machine rounded tail, and it is easy to be curved easy to break to solve existing round needle, and service life is short, maintenance is frequent, clean difficulty, labor strength is big.

The technical solution of the utility model is: it is made up of a needle stand body and the flat pin of two row's rounded tails, the backshank that it is characterized in that the flat pin of rounded tail is cylindric heeling-in in the needle stand body, the external flat pin needle body of rounded tail of needle stand is oblate cone, its both sides, cross section are parallel, two ends are arcuation, and the flat pin of two row's rounded tails is vertically arranged with flat-shaped plane.

The utility model has the advantages that since fiber in drafting process; pin is mainly to be subjected to force direction in the vertical; flat pin and vertically arrangement thereof; the intensity of flat pin is increased, distortion is little, the bending resistance flexural capacity is better than round needle; prolonged service life; compare with original round needle, can reduce by tens times of pin consumptions, reduce simultaneously to shut down and change the time of pin and the working strength on the links such as crochet hook, cleaning and row's pin.In addition, because vertical arrangement of flat pin strengthens the contact area of needle body and fiber, fibre bundle is during by needle plate, and sliver evenly, combing, drawing-off be effective, reduces consumption, improved product quality.

Description of drawings:

Fig. 1 is the flat pin needle stand of a flax roving machine rounded tail structural representation;

Fig. 2 is the front view of the flat pin of rounded tail of the flat pin needle stand of flax roving machine rounded tail;

Fig. 3 is the flat pin needle body of the rounded tail A-A cutaway view of the flat pin needle stand of flax roving machine rounded tail;

Fig. 4 is the side view of the flat pin of rounded tail of the flat pin needle stand of flax roving machine rounded tail;

Wherein: the flat pin of 1 rounded tail, 2 needle stand bodies.

Be specific embodiments of the present utility model below:

At first make the flat pin of rounded tail, select for use quality carbon tool steel to draw, grind moulding, and heat-treat.The diameter of the backshank of the flat pin of its rounded tail is 0.7mm, distance between two parallel edges of needle body lower section is 0.55mm, and the distance between the cambered surface of two ends is 0.9mm, and flat pin two rows do vertical arrangement with flat-shaped plane with the rounded tail that makes, its rounded tail heeling-in in mould, is adopted the plastic pressure injection one-shot forming.

Claims

1, the flat pin needle stand of a kind of flax roving machine rounded tail, it is made up of needle stand body and pin, the backshank end that it is characterized in that the flat pin of rounded tail is cylindric heeling-in in the needle stand body, the external needle body of needle stand is oblate cone, its both sides, cross section are parallel, two ends are arcuation, and the flat pin of two row's rounded tails is vertically arranged with flat-shaped plane.
