Abstract

The utility model relates to a piece of elastic card clothing for silk bast. A cylindrical part (except a needle point) of the card wire (2) of a piece of ordinary elastic card clothing is made into an oval shape, and a long axis of an oval section of the card wire is on a plane formed from two straight segment axes of the card wire 2. Therefore, buffer action of the card wire 2 is increased, thus the service life of the card wire is prolonged and the length of the fibre is increased.

Description

The thin,tough silk fiber crops are used fillet clothing

The utility model belongs to one and the textile machine parts, especially by bottom cloth layer be implanted with 20 ° of fillet clothings that the horn combs pin is formed of layback.

Over past ten years, in order to improve the continuous output of thin,tough silk bast fibre spinning industry combing, quality, the card clothing that is used for thin,tough silk bast fibre spinning circular comber explained hereafter develops rapidly, especially in recent years, the improvement of card clothing base fabric prescription, card wire bends to the design that 120 °-124 ° and card wire are planted the pin hole angle, strengthened the carding capacity of card wire, prolonged card wire service life, simultaneously, the continuous comb folding of comb also increases, but because its card wire is columniform except that needle point, and circular comber is that the continuous end of rod is gripped, the other end carries out meticulous combing, so work as combing in a flash, when card wire can not pass through some disorderly fibre bundles, cylindrical card wire was because stressed even, the power of bearing will be very big, and this moment, card wire will rupture, torsional deformation or damage fiber.

Task of the present utility model provides the better fillet clothing of a kind of carding property, makes the stressed buffering that obtains of card wire.

For solving above-mentioned task, the solution that the utility model is taked is: card wire is made ellipse through the circular arc point of contact to the cross section of distance needle point 2-3mm from the bottom cloth layer surface location, and the major axis of oval cross section is on the plane that card wire two straight section axis constitute, long axis length 0.65-1.65mm, minor axis length 0.4-0.85mm, arc radius 0.15-0.18mm on the major axis, arc radius 0.4-0.85mm on the minor axis.

Owing in the above-mentioned solution, adopt oval card wire, increase the cushioning effect of card wire during combing, thereby prolonged the service life of card wire, increased fibre length, improved the comb folding.Owing to only increased one procedure in technical process, processing is simple, increases cost hardly in addition.

Below in conjunction with the drawings and specific embodiments mode the utility model is described in further detail.

Fig. 1 is the front view of the utility model fillet clothing.

Fig. 2 is the A-A line profile of fillet clothing card wire shown in Figure 1.

Fig. 1 is the front view of the utility model fillet clothing: fillet clothing is made up of bottom cloth layer 1 and card wire 2.Card wire 2 bends to 120-124 ° of α and implants bottom cloth layer 1 to the bottom 4, and card wire 2 all is ellipse through crooked circular arc point of contact 3 to the cross section of distance needle point 2-3mm 6 from bottom cloth layer 1 surface location 5.

Fig. 2 is a fillet clothing card wire A-A line profile shown in Figure 1: the major axis of card wire oval cross section on the plane that card wire two straight section axis constitute, the oval part long axis length of card wire 0.60-1.65mm, the long 0.40-0.85mm of minor axis; Arc radius 0.15-0.18mm on the major axis, arc radius 0.4-0.85mm on the minor axis.Embodiment one: the long 1.42mm of oval part major axis, during the long 0.72mm of minor axis, arc radius R1 is 0.16mm on the major axis, arc radius R2 is 0.81mm on the minor axis.

The utility model can be by another embodiment: the long 1.02mm of oval part major axis, and during the long 0.56mm of minor axis, arc radius R1 is 0.17mm on the major axis, arc radius R2 is 0.675mm on the minor axis.

The utility model also can be by another embodiment: the long 0.77mm of oval part major axis, and during the long 0.47mm of minor axis, radius R1 is 0.16mm on the major axis, radius R2 is 0.550mm on the minor axis.
