Any section of the bottom cradle is basically shaped like a T, the upper surface of the transverse part of the T shape is the combined shape of a section of straight line and a section of curve connected with each other, the curve part is higher than the straight line part, having difference in height, both the straight line part and the curve part have certain thicknesses, and thereby the curved stepped bottom cradle is formed. The bottom cradle is characterized in that: the length of the straight line part is 4.0mm to 7.4mm; the corresponding length of the curve part connected with the straight line part is 16.0mm to 12.6mm, moreover, the distance A1 between the highest point of the curve part and the front edge of the straight line part is 9.0mm to 12.0mm, the distance between the highest point of the curve part and the tail end of the apron bottom cradle is 11.0mm to 8.0mm, and the curve radian radius of the curve part is 70mm; and the height difference between the curve part and the straight line part is 3.6mm to 2.0mm. The apron bottom cradle has better control on drafted silvers, and the yarn quality is greatly increased.
Description
Technical field
The utility model relates to a kind of part that is used for fine spining machine, is specially the used apron lower pin of the little roller gauge drafter of fine spining machine.
Background technology
The drafter of the ring throstle of present domestic cotton mill, the general length tape drawing mechanism that adopts the SKF type, this traditional drawing-off form, roller gauge is bigger, swimming, it is longer to distinguish, adopt length apron draft mode to be unfavorable for that the quality of spun yarn resultant yarn further improves, little roller gauge drafter can effectively solve the head of district's that swims technological difficulties, and therefore present domestic cotton mill and textile machinery factory are all in the transformation of carrying out little roller gauge drafter and renewal.Little roller gauge drafter mainly relies on drawing rollers, cushion rubber, apron, pin and downside pin acting in conjunction on the elasticity, less in addition roller gauge, realization is to the stronger control of fiber, cushion rubber, additional friction power bound pair controlling fiber motion in the middle of the mechanism that pin and curved surface ladder downside pin are formed on the elasticity is formed, the quality that guarantees the drawing-off sliver has decisive role, existing application is the T font in its arbitrary cross-section shape of downside pin of close setting drafter substantially, and the upper surface of the horizontal part of T font is the combined shaped that one section straight line links to each other with one section curve, curved portion is higher than straight line portion, has difference in height, straight line portion and curved portion all have certain thickness, have formed curved surface stairstepping downside pin.This downside pin physical dimension that is applied to the close setting drafter is compact to design, little roller gauge drafter is had specificity, help the tensioning apron, additional friction power circle in the middle of strengthening, raising is to the control degree of fiber, thereby is widely adopted in little roller gauge drafter.But further test and studies show that, this downside pin better counter extensioin fiber carries out strong control, exist and to remain improved place, its design defect is: the straight line of downside pin (plane) partial-length is longer, a little less than making its elastic acting force that supports apron, weakened the intensity of main drawing area middle part friction field, control to sliver is enough not strong, the uplift force of the peak of downside pin curved portion is also not enough, the sliver curve drawing passage that apron is formed relatively relaxes, can not control sliver effectively, be unfavorable for the high-quality of resultant yarn.
The utility model content
At the deficiencies in the prior art, the technical problems to be solved in the utility model is to improve on the basis of the apron lower pin of using on the close setting drafter, a kind of apron lower pin that is used for the close setting drawing-off is provided, and its counter extensioin sliver has better control, and yarn quality obviously improves.
The technical solution of the utility model: designing its arbitrary cross-section of a kind of apron lower pin is that shape is the T font substantially, and the upper surface of the horizontal part of T font is the combined shaped that one section straight line links to each other with one section curve, curved portion is higher than straight line portion, has difference in height, straight line portion and curved portion all have certain thickness, and the length that it is characterized in that described one section straight line portion is the 4.0-7.4 millimeter; The length of the curved portion that links to each other with straight line portion correspondingly is the 16.0-12.6 millimeter, and its peak is the 9.0-12.0 millimeter apart from straight line portion leading edge distance, peak should be the 11.0-8.0 millimeter mutually apart from the distance of apron lower pin tail end, and the curve radian radius of curved portion is 70 millimeters; The difference in height of curved portion and straight line portion is the 3.6-2.0 millimeter.
The utility model is primarily aimed at the shape of the upper surface of apron lower pin and has done to improve design, at different raw cotton, the position of downside pin working face peak is moved forward certain distance, increased the length of curve (curved surface) part, dwindle the length on downside pin straight line portion (plane) accordingly, so that strengthen near the friction field of glue ring edge position; Increase the difference in height of downside pin curved portion and straight line portion simultaneously, to strengthen the upward pressure of downside pin, further tensioning apron, enhancement curve drawing-off effect to apron; Increase the curved portion radius of the radian, it is more smooth and easy that sliver is drawn.The control to fiber has been strengthened up and down between the apron in downside pin of the present utility model design, make the distribution of draw zone internal friction circle more reasonable, on the basis of little roller gauge, more dwindled the length in the district of swimming, the distribution of fiber speed change point in the main drawing area is more moved forward, further concentrate, and make the speed change of fiber more stable to jaw.Reaching on the drawing-off basis of little roller gauge under the constant situation of other condition, using the fine spining machine of the utility model downside pin can obviously improve evenness quality, the sliver even thickness, slubbing, details obviously reduces, and the CV value reduces.The utility model is owing to be to improve design in existing application on the basis of the downside pin of the drafting system of little roller gauge, only redesigned the size of the distribution of lengths of peak position, plane and curved portion of downside pin working face and the difference in height between them, curved portion radius of the radian, change is not done at other position, therefore its structure is still simple, handling ease, easy for installation, the special-purpose curved surface ladder of little roller gauge drafter downside pin for the fine spining machine of present use can both be suitable for, so good and economic and applicability are arranged.
Description of drawings
Fig. 1 is the existing little roller gauge drafter of a utility model correspondence downside pin planform schematic diagram;
