Abstract
The present invention relates to special doffer metallic card clothing of soybean protein fibers for a medium-speed cotton opener, which belongs to the field of a special textile piece. The card clothing comprises a base part and needle teeth, wherein the needle teeth are uniformly distributed on the upper part of the base part. The present invention is characterized in that the needle teeth have double front angles, and the end parts of the needle teeth are designed to present a shape of a convex needle head, which is favorable for grabbing, carding and transferring soybean protein fibers in time. The card clothing can guarantee clear wets of the soybean protein fibers and can not have the phenomenon of wound fibers, so the quality of the spinning products can reach a good level.
Description
Technical field:
The invention belongs to the special part of weaving field, especially relate to a kind of carding machine special-purpose doffer's metallic card clothing of soybean fiber that is applicable to middling speed.
Background technology:
Soybean fiber is to be formed through wet spinning by the protein lysate that soybean extract, and group company develops successfully by the associating of the Hua Kang of Henan Province chemical-biological engineering.In March, 2000, Henan Province Hua Kang bioengineering Co., Ltd has successfully carried out suitability for industrialized production in the world first.Soybean fiber moisture absorption, good permeability, fiber is pliable and tough, fluffy, light specific gravity, warmth retention property is strong, and gloss is soft, and certain health care is arranged.But the fiber surface coefficient of friction is lower, and dynamic and static coefficient of friction difference is less, and fiber crimp elasticity is relatively poor, anterior angle α under the feasible pin tooth as shown in Figure 1
1' be 25, the tooth pitch P ' of pin tooth is 1.6 millimeters, pin tooth height overall H ' is 2.5 millimeters, base portion thickness W ' is that conventional doffer's metallic card clothing of 0.7 millimeter divides comb insufficient to soybean fiber, the fibre migration degree is not high, and yield and quality is lower, and fiber also has wrapping phenomena.
Summary of the invention:
At the problems referred to above, the special-purpose doffer's metallic card clothing of a kind of new soybean fiber that designed of the present invention.
The technical scheme of technical solution problem of the present invention is as follows:
The special-purpose doffer's metallic card clothing of a kind of soybean fiber comprises base portion 2 and is distributed on pin tooth 1 above the base portion 2, it is characterized in that the end shape of described pin tooth 1 is convex syringe needle shape, following anterior angle α
1Be 30 degree, anterior angle α
2Be 45 degree, Clearance angle β is 45 degree, the tooth pitch P of pin tooth is 1.97～2.03 millimeters, pin transverse tooth thickness degree a is 0.12～0.17 millimeter, and thickness at root of tooth b is 0.3 millimeter, and pin tooth height h is 2.75～2.85 millimeters, pin tooth height overall H is 4.48～4.52 millimeters, the density of pin tooth is 571 tooth/square inches, and the base portion thickness W of described base portion 2 is 0.82～0.92 millimeter, and base portion height C is 1.3 millimeters.
Advantage compared with prior art of the present invention is:
The present invention owing to improve has designed the process of pin tooth, base portion, help this card clothing to the extracting of soybean fiber, divide comb and shift, guaranteed the clear and no fiber wrapping phenomena of web, can make the yield and quality that spins reach good level.
Description of drawings:

The specific embodiment:
The special-purpose doffer's metallic card clothing of a kind of soybean fiber comprises base portion 2 and is distributed on pin tooth 1 above the base portion 2, it is characterized in that the end shape of described pin tooth 1 is convex syringe needle shape, following anterior angle α
1Be 30 degree, anterior angle α
2Be 45 degree, Clearance angle β is 45 degree, the tooth pitch P of pin tooth is 1.97～2.03 millimeters, pin transverse tooth thickness degree a is 0.12～0.17 millimeter, and thickness at root of tooth b is 0.3 millimeter, and pin tooth height h is 2.75～2.85 millimeters, pin tooth height overall H is 4.48～4.52 millimeters, the density of pin tooth is 571 tooth/square inches, and the base portion thickness W of described base portion 2 is 0.82～0.92 millimeter, and base portion height C is 1.3 millimeters.
Because the pin tooth 1 that the present invention is distributed on above the base portion 2 has adopted two anterior angle α
1, α
2Be convex syringe needle shape with the end shape design of pin tooth 1, can make card clothing of the present invention under supporting cylinder middling speed (280-360 rev/min) running, be very beneficial for extracting, branch comb and transfer in time to soybean fiber, can guarantee the clear and no fiber wrapping phenomena of web of soybean fiber, make spinning quality can reach good level.
