Abstract

The utility model relates to a comb sheet for sawtooth cylinders. The utility model is characterized in that the working angle, the tooth tip angle, and the tooth depth of each comb descend in sequence from front to back; the pitch angle of a front and a rear combs decreases in sequence from front to back. The constructional features cause front and back comb sheets inside a plurality of comb groups on the sawtooth cylinders to form the rule that combs change gradually one by one in the longitudinal direction. The gradual change of the comb structure on the cylinders can be enhanced, and the carding quality of the sawtooth cylinders can be improved.

Description

The carding tooth plate of sawtooth cylinder

The utility model relates to a kind of carding tooth plate of sawtooth cylinder.

Carding tooth plate is the most basic working part of sawtooth cylinder, is made up of bar and broach, and it is assembled into the broach group alternately with partition, is fixed to then on the cylinder pedestal.In the patented technology of ZL90206440.1 and two relevant sawtooth cylinders of ZL94212548.7, the structure of two kinds of carding tooth plates is disclosed, wherein the structure of broach part is identical, be characterized in the transverse tooth thickness of one group of each carding tooth plate in the broach group, the broach number, tooth depth, operating angle all is identical with tooth angle, and it is preceding, in the two groups of broach groups in back preceding and after the transverse tooth thickness of carding tooth plate, the broach number, tooth depth, operating angle and tooth angle then are inequality, and all following rule is changing, this shows, in these two kinds of sawtooth cylinders, the structural parameters of broach change by group, segmentation changes in other words conj.or perhaps, therefore, the gradually changeable of comb structure parameter not enough, and is certain, and this point can influence the further raising of branch comb quality.

The purpose of this utility model provides a kind of carding tooth plate that can further improve the sawtooth cylinder of branch comb quality.

Solution of the present utility model is that operating angle, tooth angle and the tooth depth of each broach on the carding tooth plate pursues tooth decrescence from A-P, and the angular pitch of former and later two broach from A-P by tooth decrescence.

Further illustrate detailed content of the present utility model below in conjunction with drawings and Examples.

Fig. 1: one of organization plan figure of the present utility model;

Fig. 2: two of organization plan figure of the present utility model;

Fig. 3: the A-A profile of broach part;

Fig. 4: the B of broach part is to view;

Fig. 5: the broach distribution schematic diagram of the carding tooth plate of three kinds of specifications after installing on the cylinder pedestal.

The distinctive points of the organization plan of the described two kinds of carding tooth plates of top Fig. 1 and Fig. 2 is in the part of bar 1, the structure of its broach 2 parts all is identical, operating angle δ, the tooth angle β and the tooth depth h that is to say each broach 2 on the carding tooth plate pursue tooth decrescence from A-P, and the angular pitch θ of former and later two broach 2 from A-P by tooth decrescence.Two groups of above broach groups of general installation on the cylinder pedestal, carding tooth plate in every group of broach group is all designed by such scheme, and the said structure parameter of broach 2 is formed by tooth variation decrescence from A-P, (as shown in Figure 5), so, preceding rare back gradually changeable close and that broach operating angle, tooth angle and angular pitch are pre-large post-small of the vertical density of sawtooth cylinder upper comb dent can strengthen.Certainly, the branch comb quality of sawtooth cylinder is also relevant with two horizontal structural parameters of broach, be transverse tooth thickness H and transverse pitch, wherein transverse pitch depends on the thickness of partition and carding tooth plate, the thickness of carding tooth plate in every group of broach group and partition is pressed the thin conceptual design in preceding thick back, so, the gradually changeable of the broach density on the sawtooth cylinder will strengthen on comprehensive greatly.According to the carding tooth plate of design principle design of the present utility model, its outside circle and root circle be decentraction, and at this situation, the external arc of partition should be coincide for appropriate with the root circle of carding tooth plate, can reduce the embossing phenomenon in the branch comb process like this.In addition, divide the comb quality in order further to improve, measure of the present utility model also has: four angles of the cross section of each broach 2 of carding tooth plate all form fillet r, to reduce the damage to fiber; The crown of each broach 2 of carding tooth plate forms flank angle α, and to improve the puncture ability, in like manner, the flank angle α of the carding tooth plate in every group of broach group also can design by the preceding group of little principle of tooth big back group tooth.The fixed form of broach group on the cylinder pedestal has two kinds, a kind of is mull technique, another kind is a lift-on/lift-off system, for lift-on/lift-off system, on the bar 1 of carding tooth plate hoisting structure will be set, introduce two kinds of designs below, one as shown in Figure 1, what the centre of bar 1 was provided with swallow-tail form hangs piece embedding slot 3, and both sides are provided with the polyphone hole 4 of circle hole shape; Its two as shown in Figure 2, the centre of bar 1 is provided with the polyphone hole 4 of flat rectangle, what both sides were provided with horn shape hangs piece embedding slot 3.

In sum, in the utility model, many structural parameters of the broach geometry on the reflection carding tooth plate change by tooth, and follow pre-large post-small rule, obviously, this has increased the gradually changeable of comb structure, undoubtedly, this measure will improve the branch comb quality of flush type combing sawtooth cylinder.
