Abstract
The utility model relates to highly efficient doffer card clothing, which comprises a basal part which is evenly provided with needle teeth. The utility model is characterized in that the upper part of the front sloped edge of each of the needle teeth is bent forward to form a front rake angle alpha 1 and a side rake angle alpha 2; the front rake angle alpha 1 is from 40 DEG C to 48 DEG C, and the side rake angle alpha 2 is from 25 DEG C to 30 DEG C; the back angle gamma of each of the needle teeth is from 42 DEG C to 48 DEG C, and the upper part of the back sloped edge of each of the needle teeth is in circular arc transition. The highly efficient doffer card clothing, which has strong commonality, not only can be suitable for the spinning of purified cotton and chemical fiber, but also can be suitable for the spinning of fine fibers of soybean protein, waste spinning tailings, etc.
Description
Technical field
The utility model relates to a kind of textile machinery or accessories.Specifically, be the high-effect doff clothing of using on cotton, the wool spinning equipment carding machine, be applicable to combing to soybean fiber and other various fibers.
Background technology
At present, the high-effect doff clothing of using on cotton, the wool spinning equipment carding machine, its rake angle is less, only has 25～30 °, and the preceding hypotenuse of formation rake angle is a straight flange.And tooth top portion is the flat-top or the top of cutting sth. askew.The doff clothing of this structure must segment by cotton textiles, chemical fibre, thin dawn and waste spinning leftover bits and pieces, and promptly a kind of doff clothing of specification can only be applicable to combing a kind of fiber wherein, can not be general.
Summary of the invention
The purpose of this utility model is to provide a kind of high-effect doff clothing.This doff clothing, highly versatile.
Above-mentioned purpose of the present utility model is realized by following technical solution:
High-effect doff clothing of the present utility model comprises base portion, is evenly equipped with the pin tooth on the base portion, is characterized in that the preceding hypotenuse top of pin tooth bends forward, and forming front (top) rake angle α 1 and front top rake angle α 2, and front (top) rake angle α 1 is that 40～48 °, front top rake angle α 2 are 25～30 °.The Clearance angle γ of pin tooth is 42～48 °, and to be circular arc excessive on the back hypotenuse top of pin tooth.
Such scheme of the present utility model has the following advantages:
Because high-effect doff clothing of the present utility model, the preceding hypotenuse top of its pin tooth bends forward, forming front (top) rake angle α 1 and front top rake angle α 2, and front (top) rake angle α 1 be 40～48 °, front top rake angle α 2 is 25～30 ° makes crown form dog shape, and is good to the grip effect of fiber.The scope of application is big, highly versatile.Can not only the spinning suiting cotton textiles, chemical fibre, again can the spinning suiting soybean protein and fine fibre such as waste spinning leftover bits and pieces.
In addition, because the Clearance angle γ of pin tooth is 42～48 °, and to be circular arc excessive on the back hypotenuse top of pin tooth.After the coating, its crown need not polish and polishing, can use, and is not only easy to use, and can prolong the service life of card clothing.
Description of drawings
Fig. 1 is a high-effect doff clothing structural representation of the present utility model;
Fig. 2 is that schematic diagram is looked on the left side of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, high-effect doff clothing of the present utility model comprises base portion and forms as one with base portion and be in the pin tooth on base portion top that it is excessive to be circular arc at the bottom of the tooth of tooth and between cog.The preceding hypotenuse top of pin tooth promptly bends forward near the crown place, makes this preceding hypotenuse form front (top) rake angle α 1 and front top rake angle α 2.Wherein: front (top) rake angle α 1 is 45 °, also can be the arbitrary proper angle in 42～48 ° of scopes; Front top rake angle α 2 is 28 °, also can be the arbitrary proper angle in 25～30 ° of scopes.
And Clearance angle γ is 45 °, also can be the arbitrary proper angle in 42～48 ° of scopes.In addition, to be circular arc excessive on the back hypotenuse top of pin tooth.
Claims (2)
1. high-effect doff clothing, comprise base portion, be evenly equipped with the pin tooth on the base portion, it is characterized in that the preceding hypotenuse top of pin tooth bends forward, forming front (top) rake angle (α 1) and front top rake angle (α 2), and front (top) rake angle (α 1) is that 40～48 °, front top rake angle (α 2) are 25～30 °; The Clearance angle of pin tooth (γ) is 42～48 °, and to be circular arc excessive on the back hypotenuse top of pin tooth.
2. high-effect doff clothing according to claim 1 is characterized in that total tooth depth (h) is 4.0～5.0mm.
