Abstract

The utility model relates to a comb dent structure of a refined combing sawtooth cylinder, which is composed of a plurality of groups of comb dents. The utility model is characterized in that the thickness and the depth of the dents are larger at the front and smaller at the rear, the working-angle and the dent tip are larger at the front and smaller at the rear, the transverse pitch is larger at the front and smaller at the rear, the longitudinal number of dents is less at the front and more at the rear, the edge of the comb dents forms into the rounded corner, and the position of the adjacent comb dents is aligned. Under the combined action of the structural characteristics, the utility model has the advantages of large density of the comb dents, strong puncture ability, high combing quality, and stable and reliable quality, so that the comb dent structure of refined combing sawtooth cylinder is a quantum jump in the technique of the refined combing sawtooth cylinder, and can promote the generalization and the application of the refined combing sawtooth cylinder.

Description

Combing is according to tooth cylinder comb structure

The utility model relates to a kind of comb structure of combing sawtooth cylinder.

On combing machine, the effect of combing cylinder is the front end of carded fiber palpus clump, and staple fibre, knot that the parallel ， And of straightening of fibers is removed are wherein mixed and fault.In view of traditional plants the pin cylinder in structural manufacturing process and the existing qualitatively problem of branch comb, the sawtooth cylinder has begun the alternative pin cylinder of planting at present, the branch comb quality of sawtooth cylinder is closely related with the configuration of broach, its equipping rules is that rare back is close before accomplishing as far as possible, therefore, known sawtooth cylinder structurally has following characteristics: the one, two groups or more zigzag broach group is at least arranged on the cylinder; The 2nd, the transverse tooth thickness of back one broach group is less than the transverse tooth thickness of last broach group, and the transverse pitch of back one broach group is less than the transverse pitch of last broach group, guarantee the broach lateral density with this before rare back close; The 3rd, each organize adjacent two the row broach positions stagger, increase vertical density of broach with this.But, the actual broach density deficiency that shows above-mentioned sawtooth cylinder comb structure of using, the puncture ability is relatively poor, divides the comb quality also not reach the requirement of combing.

The purpose of this utility model is to provide a kind of enough broach density that has, and the puncture ability is strong, divides the comb structure of the high combing sawtooth cylinder of comb quality.

Solve main points of the present utility model and be the operating angle of back one broach group broach and tooth angle operating angle and tooth angle, and the broach number of the every row of back one broach group is greater than the broach number of the every row of last broach group less than last broach group broach.

This specification provides the following drawings.

Fig. 2: the dress figure of broach group portion;

Fig. 3～Fig. 5: the first broach group sawtooth chip architecture figure;

Accompanying drawing has been described an embodiment of the present utility model, further illustrates content of the present utility model below in conjunction with embodiment.

Present embodiment has three groups of broach groups, and first group (1) preceding, and second group (2) are placed in the middle, the 3rd group (3) after, the broach group can also can be installed on the cylinder pedestal (4) by the setting-in structure by adhesive bond on the cylinder pedestal, present embodiment adopts the latter.Be that the broach group is formed after pivot pin (7) is fastening alternately by sawtooth sheet (5) and partition (6), And is fixed on the cylinder pedestal (4) by the setting-in structure of being made up of dovetail groove (8), dovetails (9) and stretching screw (10) that branch is located on broach group and the cylinder pedestal (4).Transverse tooth thickness (the H of broach group broach ₁, H ₂, H ₃) and transverse pitch (L _1,2,3) from first group to the 3rd group by group decrescence, the operating angle (α of broach group broach ₁, α ₂, α ₃) tooth angle (β ₁, β ₂, β ₃) and tooth depth (h ₁, h ₂, h ₃) also be by group decrescence from A-P, the broach number of the every row of broach group then is cumulative by group from A-P.The numerical value of present embodiment said structure parameter is as follows:

	The transverse tooth thickness millimeter	The transverse pitch millimeter	Operating angle	The crown angle	The tooth depth millimeter	Every capable broach number
	The transverse tooth thickness millimeter	The transverse pitch millimeter	Operating angle	The crown angle	The tooth depth millimeter	Every capable broach number	First group	??0.25	1.25-1.45 it is adjustable	??55°	??15°	????3.5	????7
Second group	??0.20	0.70-0.95 it is adjustable	??50°	??14°	????3.2	????10	First group	??0.25	1.25-1.45 it is adjustable	??55°	??15°	????3.5	????7
Second group	??0.20	0.70-0.95 it is adjustable	??50°	??14°	????3.2	????10	The 3rd group	??0.15	0.40-0.65 it is adjustable	??45°	??12°	????2.8	????12

In addition, four angles of each each broach cross section of broach group all form fillet (r ₁, r ₂, r ₃) structure, and the aligned in position of adjacent two row broach.

On the close basis, the utility model rare back before the broach lateral density, pre-large post-small three architectural features of preceding rare back close and the operating angle and the tooth angle of the vertical density of broach have been increased, broach density is increased greatly, the puncture ability is strengthened greatly, this is the essential condition of facilitating branch comb quality to improve, in addition, the broach degree of depth pre-large post-small can reduce the embossing phenomenon; The alignment of the corners of broach seamed edge and adjacent row broach also can reduce the staple fibre quantity in the cotton noils, and these all divide the comb quality to produce positive impact to improving, therefore, the utility model divide the comb quality obviously to improve, and steady quality is reliable under all multifactor comprehensive functions.We can say that the utility model is the technical quantum jump of combing sawtooth cylinder, will promote applying of combing sawtooth cylinder surely.
