Abstract

The utility model relates to cylinder card clothing for carding soybean fibers. The utility model is composed of a basal part and needle teeth on the basal part, wherein, the needle teeth are equidistantly arranged; the tooth bottom and the tooth tip of each of the needle teeth is in circular arc transition; a tooth bottom angle is a negative angle from 14 DEG to 16 DEG; a tooth rake angle thereof alpha is from 18 DEG to 22 DEG; a working angle delta is from 68 DEG to 72 DEG; a tool angle beta is from 20 DEG to DEG; tooth depth h1 is from 0.45 mm to 0.6 mm. The cylinder card clothing with a wide range of application can be used for carding purified cotton fibers or common chemical fibers, and can card and transfer soybean fibers.

Description

A kind of Bearded-needle knitted cloth

Technical field

The utility model relates to a kind of metallic card clothing.Be the Bearded-needle knitted cloth that is used for the combing soybean fiber specifically.

Background technology

2000, China succeeded in developing soybean fiber, and a kind of natural textile material of high-quality is provided again for the mankind's clothing.For adapting to the production in enormous quantities of fibre and soya, just must develop and provide a kind of Bearded-needle knitted cloth that soybean fiber is carried out combing and transfer that can be used in.

At present, the breast swift card clothing that textile industry is used, as the R-2815 type Bearded-needle knitted cloth that Switzerland Ge Lafu company produces, its anterior angle is less only to be 15 °, tooth depth reaches 0.8mm more deeply.This Bearded-needle knitted cloth can only be used for textile fiber of combing or ordinary chemical fiber, and soybean fiber is carried out combing and shift twining difficult point.Therefore, the scope of application is not wide.

Summary of the invention

The purpose of this utility model is to provide a kind of Bearded-needle knitted cloth.This card clothing is applicable to combing and transfer to difficult transfer fibers such as soybean fibers.

Above-mentioned purpose of the present utility model is realized by following technical solution:

Bearded-needle knitted cloth of the present utility model is made of base portion and the pin tooth that is on the base portion, and pin tooth wherein is equidistant layout; Its design feature is at the bottom of the tooth of pin tooth and is arc transition between crown that 14～16 ° negative angle is adopted at the tooth base angle; Its rake angle α is 18～22 °, and operating angle δ is 68～72 °, and tooth angle β is 20～30 °, and tooth depth h1 is 0.45～0.6mm.

Adopt such scheme, have the following advantages:

Because the pin rake angle of Bearded-needle knitted cloth of the present utility model is big (18～22 °), and dial set shape adopts super shallow tooth depth (0.45～0.6mm), the negative angle and the circular arc that add the tooth base angle again and be 14～16 ° link, both guaranteed effectively that soybean fiber obtained stronger branch comb on dial, can avoid it to sink down at the bottom of the pin again and do not participate in combing and transfer, solve the contradiction that the less soybean fiber of coefficient of friction is difficult for being held and easily sinks in minute comb process, guaranteed carding quality.Can be used for textile fiber of combing or ordinary chemical fiber, can carry out combing and transfer to soybean fiber again, the scope of application is wide.
