Abstract
The utility model relates to a field of textile machinery, specifically to an upper cotter with a front press bar in a drafting mechanism of a cotton spinning machine. The utility model is composed of an upper cotter rack, a left swelling riser, a right swelling riser, a left swelling spring, a right swelling spring, a distance clip and a front press bar, which is characterized in that an elongated shape front press bar is arranged at the front end of the distance clip, the intermediate section of the front press bar mutually pressing cooperated with the front end of the distance clip, a left section and a right section of the distance clip are transversely arranged against a left box and a right box of the front end of the upper cotter and are in parallel installation with an external margin of the front end of the upper cotter. The front press bar acts on a spun yarn fiber-strand of a front zone drawing section, thereby controlling a floating zone fabric to vary speed beforehand or lagging behind effectively, and improving the quality of spinning strips.
Description
Technical field
The utility model relates to field of textile machinery, is specially the pin of going up that has preceding pressure bar in the cotton spinning frame drafter.
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 preceding pressure bar are formed, it is characterized in that, the front end of spacing block be provided with one longilineal before pressure bar, its middle part is that die casting is connected with the front end of spacing block, and its left and right section right wing-rooms on either side of a one-story house horizontally set that keeps left in the top-pin rack front portion is the parallel shape setting with the external margin of top-pin rack front portion.
Technical scheme 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 top-pin rack lower end 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, having controlled the district's fiber that swims effectively 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.
Embodiment
As shown in Figure 1, 2, 3, the utility model is by top-pin rack (1), left and right tightening plate (2,3), left and right tensioner spring (4,5), spacing block (7) and preceding pressure bar (6) are formed, it is characterized in that, the front end of spacing block (7) be press-fitted one longilineal before pressure bar (6), its middle part is press-fitted mutually with the front end of spacing block (7), its the left and right section right wing-rooms on either side of a one-story house horizontally set that keeps left in top-pin rack (1) front portion, the external margin anterior with top-pin rack (1) is the parallel shape setting.The cross section of preceding pressure bar (6) is circular, and its diameter is 3 millimeters, and 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.
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.
Claims (3)
1. one kind has upward selling of preceding pressure bar, comprise top-pin rack (1), left and right tightening plate (2,3), left and right tensioner spring (4,5), spacing block (7) and preceding pressure bar (6), it is characterized in that, the front end of spacing block (7) be provided with one longilineal before pressure bar (6), its middle part is that die casting is connected with the front end of spacing block (6), its the left and right section right wing-rooms on either side of a one-story house horizontally set that keeps left in top-pin rack (1) front portion, the external margin anterior with top-pin rack (1) is the parallel shape setting.
2. going up of pressure bar sold before according to claim 1 having, and it is characterized in that, described preceding pressure bar (6) is the elongated shape rod, and its cross section can be circle, can be ellipse, also can be fan-shaped.
