Abstract

The utility model relates to a mechanical damping type tensioner without yarn sliding wear. The mechanical damping type tensioner without yarn sliding wear is characterized in that a pair of large-diameter tension bowls is adopted, when tension is adjusted, a leaf spring is pushed towards a rotor in a pressing mode through a tension adjusting screw to rub the rotor so as to produce damping force, the damping force is adjusted through pushing force of the tension adjusting screw, and due to the fact that the large-diameter tension bowls and the rotor are fixedly installed together, the damping force is transmitted to yarn thorough the tension bowls, and adjustment on the tension of the yarn is achieved. According to the purely mechanical adjustment mode, the yarn does not slide relative to a damping force providing part, the bending radius of the yarn is large, the bending curvature of the yarn is small, the mechanical damping type tensioner without yarn sliding wear is applicable to glass fibers and rock fibers, the glass fibers and the rock fibers cannot be bent or be rubbed, and the mechanical damping type tensioner without yarn sliding wear is simple, practical, reliable, good in quality and low in price.

Description

The fricton-tight wearing and tearing tensioner of mechanical damping formula yarn

Technical field

The utility model relates to a kind of tensioner for the yarn tension adjusting, especially a kind of fricton-tight wearing and tearing tensioner of mechanical damping formula yarn that is applicable to glass fibre and rock fiber yarn tension adjustment.

Background technology

The tensioner that existing glass fibre and rock cloth are used in producing, usually all be the common tensioner structure of regulating with reference to textiles for general use yarn tensions such as cotton yarn, chemical fibres, perhaps directly use common tensioner, the shared characteristics of these tensioners are: provide tension force by yarn with respect to the sliding friction of part on the tensioner, owing to provide the diameter of part of sliding friction very little, the bending radius of yarn is little so that bending curvature is large; The textiles for general use yarn that the tensioner of this structure is large for the twist, quality is soft is suitable for fully, but, quality little for the twist be hard, be afraid of bending, be afraid of glass fibre and the rock fiber of friction, the bending of sliding friction and deep camber is serious to the damage of yarn, reduced yarn strength, the generation filoplume is many, affects come into force rate and product quality;

At present, prior art requires during extra high glass electronics cloth produces at fabric quality, and what usually adopt is magnetic hysteresis damping tension device, this tensioner complex structure, expensive, energy consumption is large, is unaffordable during conventional glass fibre and rock cloth are produced.

The utility model content

The purpose of this utility model is to provide a kind of above-mentioned shortcoming that overcomes, make yarn with respect to damping force provide part without relative sliding, that large its bending curvature of yarn bending radius is little, be suitable for glass fibre and the fricton-tight wearing and tearing tensioner of the mechanical damping formula yarn rock fiber, super quality and competitive price being afraid of bending and being afraid of friction;

For achieving the above object, the technical scheme that the utility model adopts is: the fricton-tight wearing and tearing tensioner of this kind mechanical damping formula yarn, comprise lower tension pulley, upper tension pulley, tension pulley pressing plate, pressing plate hold-down screw, yarn sley, yarn retaining plate, porcelain eye, it is characterized in that: lower tension pulley, upper tension pulley fit on the convex shoulder of rotor by centre bore, on upper tension pulley, be furnished with the tension pulley pressing plate, the tension pulley pressing plate by the pressing plate hold-down screw with lower tension pulley, upper tension pulley be fixed on rotor above; Be provided with cylinder below the rotor convex shoulder, be provided with looping pit in cylinder, the looping pit central shaft is armature spindle; The tensioner seat is provided with cannelure, and is provided with dead eye at the cylinder axis at cannelure middle part; Rotor is by self set looping pit, and on the cylinder axis periphery at the set cannelure middle part of tensioner seat, the armature spindle of rotor fits in the set dead eye of tensioner seat movingly, and the rotor axle head also stretches out outside the dead eye aperture; Cannelure groove lateral wall at the tensioner seat is provided with spring groove, in the cannelure bottom land and in spring groove one side, is furnished with the spring bolt, the tensioner seat is on 90 °-180 ° the periphery, to be furnished with the tension adjustment screw at distance spring film trap, and the head of tension adjustment screw stretches out in cannelure; After one end of spring fits over spring groove, walk around the outer half cycle of spring bolt, and be fixed on the outer half cycle of spring bolt, the other end of spring is assigned in above the head of tension adjustment screw; Tensioner seat outer Monday of side is provided with uncovered hole, by the tensioner hold-down screw, with the tensioner seat and on accessory be fixed on the steel pipe of bobbin cradle; Yarn retaining plate is packed on the set fitting surface of tensioner seat one side; Porcelain eye is packed in the centre bore of yarn retaining plate; Yarn sley is packed on the set fitting surface of tensioner seat periphery by the yarn sley hold-down screw;

The fricton-tight wearing and tearing tensioner of described a kind of mechanical damping formula yarn, it is characterized in that: spring is sheet, and the other end of spring is made as to the crooked deep-slotted chip breaker of tension adjustment screw, and the head of tension adjustment screw is assigned in its deep-slotted chip breaker.

The utility model beneficial effect compared with prior art: the hole of porcelain eye enters tensioner to the utility model on the yarn retaining plate because yarn is passed in employing, from the below of yarn sley around the right back to tension pulley, behind a circle, leave tensioner from the top of yarn sley again in the annular that between two tension pulleies, forms " V " the shape groove, yarn drives the tension pulley rotation like this, without relative sliding, avoided yarn injured because of friction between the two; Adopt yarn sley avoided yarn report to the leadship after accomplishing a task because of self and twine wear and tear injured; Because the annular radius of annular " V " the shape groove that forms between two tension pulleies is large, bending radius ambassador's bending curvature of yarn is little, has avoided yarn injured because of bending; Adopt the tension adjustment screw that springs is pushed to rotor, friction bowl produces damping force, come the size of damping adjusting power by the thrust size of tension adjustment screw, because tension pulley and rotor are solidly installed, so damping force is passed to yarn by tension pulley, realization is to the adjusting of yarn tension, and the regulative mode of this Purely mechanical is simple and practical reliable, super quality and competitive price.
