Abstract

The invention relates to a gasket-air pressure combined type yarn tension exerting control device which solves problems that a gasket type tension device cannot meet requirements of high-speed weaving devices and the like in simple mode. Pressure generated by a tension gasket 7 is converted to air pressure through a pressure-bearing air bag 6, the air pressure is transmitted to the portion where tension is exerted through a pipeline 5 and restored to pressure through a restoring air bag 4, and the pressure drives a tension disc 3 to control tension of a yarn 1. Gasket pressuring mode is adopted for the yarn tension device, the existing experience and the existing process technology can be used, knitting and check up are very visual. The tension disc portion used for controlling is arranged at the position different from the gasket device and has no direction requirements so that the gasket-air pressure type yarn tension device can be used on automatic winders. The control force of the gasket-air pressure type yarn tension device is obtained through air pressure restoring so that the gasket-air pressure type yarn tension device is light in structure and small in added tension unevenness when the yarns passes at high speed, and can be used on parts of various high-speed weaving devices where yarn tension is needed to be controlled.

Description

Packing ring-vapour-pressure type thread tension device

Technical field

The present invention relates to the textile machine apparatus field, is a kind of for apply the control setup of tension force to yarn.

Background technology

On the equipment such as warping machine, bobbin-winding machine, warp sizing machine and loom of Textile Engineering, in order to guarantee that yarn conditions meets technological requirement, all need the installation tension device, make yarn realize reeling or carrying under the some tension effect, the main flow tensioner has washer type, spring loaded and three kinds of forms of vapour-pressure type at present.The tensioner of which kind of mode no matter, when yarn by the time, because the plucked of yarn itself must cause beating of the associated components such as tension pulley that contact with it, be called passive beating, thisly beat and can produce a harmful subsidiary load that acts on yarn, even can cause Yarn break.Can prove, the passive harmful subsidiary load produced of beating is directly proportional to the yarn speed passed through, and the quality also had to the parts itself of beating is directly proportional.

The washer type tensioner has the packing ring of different quality by configuration, realize pre-tension under Action of Gravity Field, advantage is that pressurization is directly perceived, facilitate machine and inspection on technique, but also larger with passive the produced harmful subsidiary load of beating, yarn speed by the washer type tensioner is higher, harmful subsidiary load is also more obvious on the impact of yarn, therefore it is not suitable with the needs of current high speed Weaving device, and the washer type tensioner has clear and definite requirement to installation direction, must make packing ring be subject to the force direction vertical ground, be difficult to application on some equipment.

Spring loaded tensioner and the common advantage of vapour-pressure type tensioner are that passive parts sole mass of beating is less, therefore harmful subsidiary load is less, in widespread attention in the high speed Weaving device, but the spring loaded tensioner is pressured contracting spring realizes that tension force applies, on technique, machine and check come intuitively not as washer type, and spring is difficult to guarantee that technique correctly goes up machine after with the passing of time being out of shape; The vapour-pressure type tensioner needs to have air compressor and complicated control system and delivery system, and equipment complexity and cost are high, only have at present in the minority novel device and just are used.

Summary of the invention

The object of the present invention is to provide and a kind ofly simple and practical can adapt to the yarn tension control device that yarn passes through at a high speed.

The technical solution used in the present invention is a set of independently tenslator of configuration on every one thread, the stress that this covering device produces with the tension washer deadweight, convert gas pressure intensity to by the pressure-bearing air bag, this pressure is sent to the position that applies tension force with pipeline, with the reduction air bag, pressure is reduced into to pressure again, with this press belt dynamic tension dish, controls yarn tension.

The accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention will be further described.

In figure, 1 is yarn, the 2nd, and lower tension pulley, the 3rd, upper tension pulley, the 4th, reduction air bag, the 5th, flexible pipe, the 6th, pressure-bearing air bag, the 7th, packing ring.

Yarn 1 passes through between the upper tension pulley 3 of fixing lower tension pulley 2 and activity, upper tension pulley 3 obtains pressure by reduction air bag 4, reduction air bag 4 forms enclosed cavity with pressure-bearing air bag 6 and flexible pipe 5, packing ring 7 vertically is placed on pressure-bearing air bag 6, the quality of packing ring is configured according to yarn is controlled to technological requirement, the pressure of its generation converts gas pressure intensity to by pressure-bearing air bag 6, its size is directly proportional to the packing ring quality, gas pressure intensity is delivered in reduction air bag 4 by flexible pipe, is reduced into the pressure to upper tension pulley 3.

This tensioner has on washer type tensioner technique the advantages such as machine is convenient, directly perceived, have again spring loaded and and the passive component structural of beating of participation that has of vapour-pressure type tensioner light and handy, yarn at a high speed by the time produces and is harmful to the smaller advantage of additional tension, the two is combined, form a set of simple and practical packing ring that can adapt to high speed Weaving device needs-vapour-pressure type thread tension device.

The specific embodiment

Pressure-bearing air bag, reduction air bag and delivery pipe can be compressing with plastics, it and packing ring and tension pulley form a set of tensioner, the yarn that applies tension force for every needs on Weaving device all configures a set of such tensioner, fully independent between each tensioner.

Be exactly the place that needs the configuration thread tension device existing specifically, a correct position is selected in the place that such as spool rack, automatic winder frame, warp sizing machine limit, through frame, loom weft yarn frame etc., tensioner need to be set, at right angle setting pressure-bearing air bag and tension washer, purpose is to convert the pressure of tension washer to gas pressure intensity.Control the place of tension force at needs reduction air bag and tension pulley are installed, installation direction can need determine according to device structure, and the pressure-bearing air bag connects and gets final product with flexible pipe between air bag with reducing.Reduction air bag and tension pulley also can be designed to integrative-structure.

Effect analysis

In front on described Weaving device, all to need the configuration tensioner, only a warping machine will configure a hundreds of tensioner in quantity, therefore manufacturing cost, the convenient and practical property of device, to be simple and easy to maintainability etc. be all the subject matter that people will consider.The present invention is on apparatus structure, and every cover tensioner, except packing ring and tension pulley, only needs two ballonets and joining flexible pipe, therefore mechanism simply very easily realizes, low cost of manufacture, and each tensioner independently uses, do not need centralized management, do not increase complexity and the manufacturing cost of equipment.The yarn tension configuration adopts the packing ring adding pressure type, when technological design, can adopt existing experience and technical data, and on technique, machine and inspection are also very directly perceived.Due to gas pressure intensity directionless requirement, the reduction air bag can be arranged to according to the requirement of device structure any direction.This has larger structure adaptability for equipment such as automatic winders.Because light and handy with the block construction of yarn contact portion, the harmful subsidiary load when passive beating, yarn produced is little, therefore is applicable to very much the occasion that high speed yarn passes through, in the situation that current Weaving device, to high speed development, necessarily has wide application space.
