Abstract

The utility model discloses metallic card clothing of a coarse carding machine. The metallic card clothing comprises a base part, wherein main teeth are uniformly distributed at the base part, an auxiliary tooth is arranged at the front part of each main tooth, and a notch is formed between the main tooth and the auxiliary tooth; and each main tooth adopts an arc back tooth provided with an arc working surface, each auxiliary tooth adopts an leftwards inverted E-shaped tooth, and the main tooth and the auxiliary tooth are connected through a transition plate. With the adoption of the metallic card clothing of the coarse carding machine, the impurity tolerance capacity of the metallic card clothing can be improved, and fiber damage and cylinder winding phenomenon are reduced, so that flexible card clothing can be probably replaced with the metallic card clothing in a coarse carding procedure, and the wool carding efficiency is improved.

Description

The metallic card clothing of wool card

Technical field

The utility model relates to field of textile machinery, relates in particular to combing machine for fur card clothing field.

Background technology

Be applied at present card clothing on the cylinder of wool card still taking fillet clothing as main.Metallic card clothing long service life, carding capacity are strong, and the card stripping operation that can also remove fillet clothing from reduces labour intensity, thereby in the operation such as comb and parallel cotton fibers prior to spinning, combing wool, has been used widely simultaneously; But the hard impurity in common and braid wool is more, easily scratch card clothing; Simultaneously because metallic card clothing carding capacity is strong, also larger to fibre damage; Most important shortcoming is: metallic card clothing backlash is shallow, the assorted ability of appearance, cannot effectively remove the impurity in common and braid wool, affects fleece quality.Thereby metallic card clothing is not yet used widely in careless hair machine field.

Present stage has had after metallic card clothing is improved and has been applied to the trial in wool card, and main improvement thinking is: increase pin wide, to improve the ABRASION RESISTANCE of card clothing; Reduce pin high, to reduce fibre damage and around cylinder, reinforcing fibre transfer ability; Reduce transverse pitch, to improve the assorted ability of holding.But only rely on these to improve, metal screen cloth still cannot adapt to the technical requirement of wool card.Current development trend is that flute profile is improved, to improve the assorted ability of appearance of metallic card clothing.

Utility model content

The applicant holds the problem of assorted ability for existing metallic card clothing, improve research, a kind of metallic card clothing of wool card is provided, it can improve the assorted ability of appearance of metallic card clothing and reduce fibre damage and around cylinder phenomenon, thereby in thick carding process, replace fillet clothing to become possibility with metallic card clothing, improve the efficiency of wool carded.

The technical solution of the utility model is as follows:

A metallic card clothing for wool card, comprises base portion, is evenly equipped with main tooth on described base portion, and the front portion of main tooth is equipped with secondary tooth, jagged between described main tooth and described secondary tooth; Described main tooth is the arc back of the body tooth with arc working face, and described secondary tooth is chevron tooth, between described main tooth and secondary tooth, is connected by rebound.

Its further technical scheme is: a side of described rebound is with slope, thereby forms guide groove between described main tooth and the tooth root of described secondary tooth; The tooth depth of described main tooth is greater than the tooth depth of described secondary tooth.

The beneficial effects of the utility model are:

Main tooth is the arc back of the body tooth with arc working face, and crown intensity is high, carding capacity is strong, mainly plays carding role; Secondary tooth is chevron tooth, carding capacity a little less than, Main Function is to reduce the effective tooth depth of main tooth in the time of carding, weakens the damage to fiber; Rebound plays the effect of main tooth and secondary tooth that connects, the intensity of increase tooth on the one hand, and domatic the formed guide groove of one skew back can improve the assorted ability of appearance of card clothing on the other hand.

Thereby the utility model can improve the assorted ability of appearance of metallic card clothing, reduce the damage of metallic card clothing to wool fibre simultaneously, ensure product quality; In addition, crown of the present utility model has good crown intensity, can adapt to the more thick carding process of hard impurity.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.

If Fig. 1 is to as shown in Fig. 4, the utility model comprises base portion 4, is evenly equipped with main tooth 1 on base portion 4, and the front portion of each main tooth 1 is equipped with secondary tooth 3, between main tooth 1 and secondary tooth 3 jagged 2; Main tooth 1 is the arc back of the body tooth with arc working face, and this profile of tooth carding effect is good, and crown intensity is large; Secondary tooth 3 is chevron tooth, and this profile of tooth does not have carding role substantially, mainly plays the effect that reduces effective wokring depth of tooth of main tooth 1 in the time of carding, thereby reduces the damage to wool fibre, thereby the tooth depth of secondary tooth 3 is lower than the tooth depth of main tooth 1.Between main tooth 1 and secondary tooth 3, be connected by rebound 5, a side of described rebound 5 is with slope 6; Sloping guide groove 8 is with in one of the common formation of tooth root of slope 6, main tooth 1 and secondary tooth 3, the impurity in common and braid wool is inducted into guide groove 8 by breach 2, the space 7 between the two row's metallic card clothing that are arranged side by side introduced impurity again by guide groove 8, thereby improved the assorted ability of appearance of metallic card clothing.

More than describing is to explanation of the present utility model, is not to restriction of the present utility model, and the utility model limited range is referring to claim.Without prejudice to the utility model basic structure in the situation that, the utility model can be done any type of amendment.

Claims

1. a metallic card clothing for wool card, is characterized in that: comprise base portion (4), be evenly equipped with main tooth (1) on base portion (4), the front portion of main tooth (1) is equipped with secondary tooth (3), between main tooth (1) and secondary tooth (3) jagged (2); Main tooth (1) is the arc back of the body tooth with arc working face, and secondary tooth (3) is chevron tooth, between main tooth (1) and secondary tooth (3), is connected by rebound (5); One side of described rebound (5) is with slope (6), thereby forms guide groove (8) between main tooth (1) and the tooth root of secondary tooth (3); The tooth depth of main tooth (1) is greater than the tooth depth of secondary tooth (3).
