Abstract
The utility model relates to the field of textile machinery, in particular to a top pin of an additional front press bar of a drafting mechanism of a cotton spinning machine. The utility model is composed of a top pin rack, a tension bridle board, a tension bridle spring, a distance clip and a front press bar. The front portion of the top pin is equipped with two press bars of a reversed L shape. A minor face of the top pin is directly disposed on an inboard of the tension bridle board, and the minor face and the top pin rack are in press fit. The long edge of the top pin is arranged transversely at the front top pin leaning two left-and-right boxes, and the long edge of the front portion of the top pin are arranged parallel to an external margin of the front portion of the top pin rack. Extendible arms which are perpendicular to the tension bridle board can be respectively disposed on the inboard of the tension bridle board. Two front press bars which are in the shape of '-'are arranged, and one end of the two front press bars which are in the shape of '-' respectively forms press fit perpendicular to the two left-and-right boxes arranged in the front portion of the top pin body and at the front end of a right and a left extendible arm, and is arranged parallel to the external margin of the front portion of the top pin body. Because the front press bar acts on strand of fibers of spun yarns of an attack zone of a drafting segment, the beforehand and the lagging of varying speed of a floating region fiber can be effectively controlled and the quality of a spinning evenness is improved.
Description
Technical field
The utility model relates to field of textile machinery, and the going up of additional preceding pressure bar that is specially in the cotton spinning frame drafter sold.
Background technology
Be used for cotton spinning frame at present and mainly contain board-like going up on pin and the elasticity and sell, the board-like pin of going up can be divided on the metal pin and carbon fibre (nylon) and goes up pin, sell on the elasticity be divided into again sell on the vertical tensioner elasticity and horizontal tensioner elasticity on sell.The above-mentioned pin product of going up is in the cotton spinning frame course of work, make fiber (especially staple fibre) changeable in the noncontrolled area movement velocity, wayward to some extent, fluctuation is big, cause the final products yarn evenness inhomogeneous, seriously hindered the further raising of product quality.
The utility model content
In order to overcome above-mentioned defective, effectively controlling fiber (especially staple fibre) improves textile quality in the motion state of noncontrolled area to the purpose of this utility model greatly exactly.
The purpose of this utility model is achieved in that it is by top-pin rack, left and right tightening plate, left and right tensioner spring, spacing block and left and right preceding pressure bar are formed, it is characterized in that, be provided with the pressure bar of two " 7 " fonts in the front portion of last pin, one length of side, short on one side, should be an angle of 90 degrees between the both sides, its minor face is directly inboard at left and right tightening plate to be that die casting is connected with top-pin rack, its long limit right wing-rooms on either side of a one-story house horizontally set that keeps left in last pin front portion, the external margin of the long limit of preceding pressure bar and last shank front portion is the parallel shape setting.
The purpose of this utility model can also realize by following technique measures: in left and right tightening plate inboard an adjutage that becomes vertical direction with it is set respectively, it is left and right adjutage, the preceding pressure bar that two " one " fonts are arranged, the one end is that die casting is connected at the anterior left and right sides of last shank wing-rooms on either side of a one-story house with left and right adjutage front end respectively, and being mutually vertical direction, the external margin of pressure bar and last shank front portion is the parallel shape setting before " one " font.
Two kinds of technical schemes above described both had been applicable on the elasticity sells, and comprises on the vertical tensioner elasticity selling on the pin and horizontal tensioner elasticity, also is applicable to the board-like pin of going up fully, comprises that pin and carbon fibre (nylon) are upward sold on the metal.
Pressure bar is the elongated shape rod before described, and its cross section can be circle, can be ellipse, also can be fan-shaped.
The diameter of preceding pressure bar is 1 to 5 millimeter, its length is suitable with corresponding tightening plate width, before in the middle part of pressure bar center extended line and the last pin distance of front end built-in edge be 1 to 4.5 millimeter, the vertical range of the planar extension face when pressure bar center line and tightening plate are in relaxed state is for o.1 to 2.5 millimeters.
Preceding pressure bar acts on the spun yarn yarn of proparea drawing-off section, makes yarn produce a new friction field in proparea drawing-off section, effectively having controlled the district's fiber that swims and having shifted to an earlier date or the hysteresis speed change, has guaranteed that the spinning evenness quality reaches quite desirable degree.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
As Fig. 1, shown in Figure 2, the utility model is by top-pin rack (1), a left side, right tightening plate (2,3), a left side, right tensioner spring (4,5), a spacing block (8) and a left side, right front pressure bar (6,7) form, be provided with the pressure bar (6 of two " 7 " fonts in the front portion of top-pin rack (1), 7) (length of side, short on one side, should be an angle of 90 degrees between the both sides), its minor face is directly on a left side, right tightening plate (2,3) inboard is press-fitted mutually with top-pin rack (1), its long limit right wing-rooms on either side of a one-story house horizontally set that keeps left in top-pin rack (1) front portion, preceding pressure bar (6,7) the anterior external margin of long limit and top-pin rack (1) is the parallel shape setting.Spacing block (8) is clamped on the middle part, lower end of top-pin rack (1) by the spacing block sandwich (13) on the top-pin rack (1).The cross section of pressure bar (6,7) is circular before left and right, its diameter is 3 millimeters, the distance of its center extended line and top-pin rack (1) middle part front end built-in edge is 3 millimeters, and the vertical range of the planar extension face when its center line and tightening plate are in relaxed state is 2 millimeters.
As shown in Figure 3, Figure 4, the utility model respectively is provided with an adjutage that becomes vertical direction with it in left and right tightening plate (2,3) inboard, be left and right adjutage (9,10), the preceding pressure bar (11,12) that two " one " fonts are arranged, the one end becomes vertical direction to be press-fitted at the anterior left and right sides of top-pin rack (1) wing-rooms on either side of a one-story house with left and right adjutage (9,10) front end respectively, and pressure bar (11,12) is the parallel shape setting with the external margin of top-pin rack (1) front portion before " one " font.Spacing block (8) is clamped on the middle part, lower end of top-pin rack (1) by the spacing block sandwich (13) on the top-pin rack (1).The cross section of pressure bar (11,12) was circular before " one " font was left and right, its diameter is 3 millimeters, the distance of its center extended line and top-pin rack (1) middle part front end built-in edge is 3 millimeters, and the vertical range of the planar extension face when its center line and tightening plate are in relaxed state is 1 millimeter.
Test shows that pressure bar is placed on the pin front portion and more can controls yarn movement speed effectively than being placed on the pin rear portion, can improve the class of spun yarn product better, is that better condition is created in the foreign exchange earning of spinning products.
Above-described embodiment is more preferably two kinds of situations of the specific embodiment of the utility model, and common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.
