The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is explained in detail.
As shown in Figure 1,3, a kind of device for adjusting tension of yarn, comprise the overfeeding roller (1) being fixed in rotating shaft (11) and be positioned at the circular arc position rack (3) under it, circular arc semi-surrounding overfeeding roller (1), on position rack (3), be fixed with the deflection roller (2) that can rotate freely, deflection roller (2) is at the upper position changeable of position rack (3); Overfeeding roller (1) comprises two overfeeding rings (4) of clipping together with clamping element (7), the edge that two overfeeding rings (4) are adjacent to is provided with a circle salient point (5) of proper alignment, the interlaced engagement of two row's salient points (5), the reverse side that two overfeeding rings (4) are adjacent to is respectively equipped with the bound edge (6) perpendicular to its face, clamping element (7) clamps overfeeding ring (4) and locks with the connecting thread it from overfeeding ring (4) both sides, connecting thread is by the holes for clamping (8) in the middle of overfeeding ring (4); The corner cross section of bound edge (6) is circular arc, two circular arcs are at the upper overfeeding groove (9) that forms of overfeeding roller (1), overfeeding groove (9) bottom is exactly intermeshing salient point (5), overfeeding groove (9) and salient point (5) surface scribble ganoid yarn coating, and it is made for high-abrasive material.
As shown in Figure 2, the yarn (12) wrapping on overfeeding roller (1) is tapped on overfeeding groove (9) the intermeshing salient point in bottom (5), form S shape thread path, yarn (12) is partly being clamped during by intermeshing salient point (5), and during rotation, overfeeding roller (1) forms the force of sliding friction to yarn (12) thus; The yarn (12) on overfeeding roller (1) top is fixed with the angle of overfeeding roller (1), when the position of the deflection roller (2) of overfeeding roller (1) bottom on position rack (3) changes, the yarn (12) of overfeeding roller (1) bottom changes with the angle of overfeeding roller (1), yarn (12) arc length wrapping on overfeeding roller (1) changes thereupon, and overfeeding roller (1) also changes the force of sliding friction of yarn (12) thereupon; The rotational line speed that overfeeding roller (1) salient point (5) is located is greater than yarn (12) speed of service, yarn skids on S shape thread path, and the rotational line speed that change salient point (5) is located and the speed ratio of yarn (12) speed of service be the force of sliding friction of adjustable overfeeding roller (1) to yarn also.
During the utility model work, overfeeding roller (1) clockwise rotates, yarn (12) up moves, deflection roller (2) rotates counterclockwise under yarn (12) drives, by overfeeding roller (1) to the force of sliding friction effect of yarn after, after yarn (12) tension force of overfeeding roller (1) bottom is transmitted to overfeeding roller (1) top, yarn tension diminishes.
As shown in Figure 2, in the constant situation of other conditions, deflection roller (2) is moved right, yarn (12) arc length being enclosed on overfeeding roller (1) becomes large, overfeeding roller (1) increases the sliding friction of yarn (12), otherwise diminishes; In the situation that other conditions are constant, the rotary speed of overfeeding roller (1) is increased, overfeeding roller (1) increases the sliding friction of yarn (12), otherwise diminishes.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
