Abstract
The utility model relates to a lower pin of a leather collar of a fine spinning machine, belonging to a textile machinery component, in particular to a lower pin of a leather collar of a fine spinning machine. The cross section of the lower pin is T-shaped and consists of a front bulge (1), a rear bulge (2) and a central column (3). The lower pin is characterized in that a distance between the front end of the front bulge and the central column is 7.5-8.5mm; a distance between the rear end of the rear bulge and the central column is 8.5-9.5mm; an installation angle at the front end of the bottom of the central column is 13-15 DEG; and the width of the bottom of the central column is 1.5-2.5mm. The lower pin disclosed by the utility model has the positive effects of convenience for manufacturing, simpleness and convenience for maintenance, lower cost and improved spinning quality.
Description
Technical field
The utility model belongs to textile machinery component, particularly relates to a kind of apron lower pin that is used for fine spining machine.
Background technology
What domestic fine spining machine generally adopted is the apron draft form of length apron combination; Downside pin becomes the apron control element with mutual group such as upper leather collar pin, apron tensioner, nip gauge regulating blocks; Effect is the control of strengthening floating fiber, obtains rational friction field, improves spinning quality., middle roller preceding through shortening spaces, and the length of dwindling the district of swimming is one of major measure of improving on the cotton spinning bar evenness to help the control to staple fibre.The downside pin installation site of present domestic use is commonly 9.5 millimeters to the distance of front end, has limited the shortening preceding, that middle roller spaces, and has hindered the further raising of yarn quality; The distance of downside pin installation site and rear end is commonly 10 millimeters, with the middle roller hypotelorism, is easy to take place in the apron operation process squeeze and hinders.
The utility model content
The purpose of the utility model is to provide a kind of fine spining machine apron lower pin, to overcome the deficiency of above-mentioned prior art, to reach the reliable and stable pressure and the purpose of top roller location accurately is provided.
The fine spining machine apron lower pin that the utility model provided, its cross sectional shape are " T " shape, by lordosis, the back is protruding and neutrally constitute, and it is characterized in that the distance between lordosis front end and the neutrality is 7.5 millimeters～8.5 millimeters; Distance between protruding rear end, back and the neutrality is 8.5 millimeters～9.5 millimeters; It is 13 °～15 ° that neutral bottom front has established angle; Neutral bottom width is 1.5 millimeters～2.5 millimeters.
Compared with prior art, the utility model has shortened the distance of installation site and front roller, i.e. distance between lordosis front end and the neutrality, and before further shortening, middle roller spaces, the length in the district that can reduce to swim improves spinning quality; Simultaneously, the distance between installation site and the middle roller of having extended, promptly the distance between protruding rear end, back and the neutrality makes down the gap increasing between apron and the middle roller, has avoided the crowded wound in the operation process; Changing the installation site angle is the established angle of neutral bottom front, has avoided the interference of time apron and downside pin.In a word; The utility model has reduced length of floating area; Avoided taking place in the operation process to squeeze problems such as wound, following apron and downside pin interference, and adopted former installation site size constancy, need not change the middle roller slide during transformation; Reduced improvement cost, have be convenient to make, easy maintenance, cost are lower, the good effect that improves spinning quality.
Description of drawings
Accompanying drawing is the section structure sketch map of the utility model, wherein,
1, lordosis; 2, the back is protruding; 3, neutrality.
The specific embodiment
Fine spining machine apron lower pin as shown in the figure, that the utility model provided, its cross sectional shape are " T " shape, are made up of lordosis 1, back protruding 2 and neutral 3.Distance between lordosis front end and the neutrality is 7.5 millimeters～8.5 millimeters, has shortened the distance of installation site and front roller, and middle roller spaces before can shortening; Distance between back protruding rear end and the neutrality is 8.5 millimeters～9.5 millimeters, and the distance between installation site and the middle roller of having extended is avoided down crushing injury in the apron operation process; It is 13 °～15 ° that neutral bottom front has established angle; Neutral bottom width is 1.5 millimeters～2.5 millimeters, on the basis of not changing former middle roller slide, has avoided in time apron operation process interference with downside pin.
