Abstract
The utility model discloses a special cylinder rack, which comprises a base portion and needle teeth evenly arranged on the base portion. The needle teeth are arranged by adopting double front rake angles and double circular arc curved surfaces, an upper front rake angle alpha 1 of the needle teeth is 20 degrees, the lower front rake angle alpha 2 of the needle teeth is 25 degrees, a tangential angle beta 1 of a left-side circular arc curved surface is 45 degrees, and a tangential angle beta 1 of a right-side circular arc curved surface is 15 degrees. The pitch P of the needle teeth is 1.5mm, the thickness of the needle teeth is 0.06mm, the thickness b of the tooth root is 0.3mm, and the height of the tooth top is 0.5mm. The overall height H of needle teeth is 2.5mm, the thickness W of the base portion is 0.6mm, and the height C of the base portion is 1.2mm. The special cylinder rack adopts the double front rake angles and the double circular arc curved surfaces, thereby facilitating holding, carding and timely transferring of the rack to milk fibers, avoiding intertwining phenomenon of the milk fibers and enabling the yarn producing quality to reach an excellent level.
Description
Technical field
The utility model belongs to the special part technical field of weaving, is specifically related to a kind of special-purpose cylinder tooth bar.
Background technology
Milk fibre is to be formed by weaving through wet method the protein lysate that milk extract, milk fibre moisture absorption, good permeability, and fiber is pliable and tough; Light specific gravity, warmth retention property is good, but the fiber surface coefficient of friction is lower; Dynamic and static coefficient of friction difference is less, and fiber crimp elasticity is relatively poor, and pin rake angle α ' is 15 °; The tooth pitch P ' of pin tooth is 1.6 millimeters, and pin tooth height overall H ' is 2.5 millimeters, and base portion thickness W ' is that 0.7 millimeter conventional cylinder tooth bar milk fibre divides comb insufficient; The fibre migration degree is not high, and output is lower, and fiber also has wrapping phenomena.
Summary of the invention
The purpose of the utility model is to provide a kind of can guarantee that fiber branch comb is abundant, shift timely, as to solve fiber winding problem special-purpose cylinder tooth bar.
The technical solution of the utility model is:
A kind of special-purpose cylinder tooth bar comprises base portion and is distributed on the pin tooth above the base portion, it is characterized in that: the pin tooth adopts two anterior angles and two circular arc camber configurations, anterior angle α on its pin tooth
1Be 20 °, anterior angle α under the pin tooth
2Be 25 °, the left circles arc surface β that cuts angle
1Be 45 °, the right circles arc surface β that cuts angle
2Be 15 °, the tooth pitch P of pin tooth is 1.5 millimeters, and pin transverse tooth thickness degree a is 0.06 millimeter, and thickness at root of tooth b is 0.3 millimeter, and crown height h is 0.5 millimeter, and pin tooth overall height H is 2.5 millimeters, and the base portion thickness W of described base portion is 0.6 millimeter, and base portion height C is 1.2 millimeters.
The utility model adopted two anterior angles with about two circular arc cambers configurations, help this tooth bar to the gripping of milk fibre, combing with in time shift, avoided the wrapping phenomena of milk fibre, make the spinning yield and quality reach good level.
