Abstract

The invention mainly discloses an adjustor capable of automatically adjusting yarn tension. The adjustor comprises a tension detector, a servo motor, a first shaft, a second shaft, a first yarn guide and a second yarn guide, the servo motor is connected with and drives the first shaft provided with the first yarn guide to rotate, the first shaft and the second shaft provided with the second yarn guide are in mesh transmission through gears, and a yarn penetrates through the first yarn guide and the second yarn guide sequentially and penetrates through the tension detector for tension detection. The servo motor directly or indirectly drives the first shaft and the second shaft to rotate, and the first shaft and the second shaft are in mesh transmission through the gears, so that the first shaft and the second shaft rotate oppositely, and finally the first yarn guide and the second yarn guide are staggered by opposite angles. By the means, the yarn passing path and the yarn passing curvature are changed, so that yarn tension is changed.

Description

A kind of regulating control of automatically regulating yarn tension

Technical field

The present invention relates to technical field of textile machine, special relevant with a kind of regulating control of automatically regulating yarn tension.

Background technology

In field of textile machinery, institute's textile product quality of producing is all relevant with the Tension Control adjusting of yarn in the braiding process on a lot of Textile Machinery, and tension difference causes the density variation of on textile product different batches even same batch, has a strong impact on quality.

It much all is that this just will certainly produce the inconsistent problem of tension fluctuation property, and labour intensity is big by operating personal manual regulation by rule of thumb that existing yarn tension is regulated.

In order to address the above problem, the inventor designs a kind of regulating control of automatically regulating yarn tension, and this case produces thus.

Summary of the invention

Main purpose of the present invention provides a kind of regulating control of automatically regulating yarn tension, detects yarn tension, and automatically adjusts according to yarn tension.

In order to achieve the above object, the present invention realizes through following technical scheme:

A kind of regulating control of automatically regulating yarn tension comprises tension detector, servomotor, primary shaft, second, first filar guide and second filar guide; Servomotor connects drive installation has the primary shaft of first filar guide to rotate, and primary shaft passes through meshed transmission gear with second that second filar guide is installed, and yarn passes first filar guide and second filar guide successively, and passes tension detector reception tension force and detect.

The signal conveys of described tension detector is to the Single-chip Controlling unit, and Single-chip Controlling unit controls end connects driven by servomotor.

Described servomotor drives to primary shaft through a pair of crowngear connection.

Described primary shaft is parallel with second, and is up and down and is in staggered distribution.

Be provided with the positioning guide wire device in the middle of described first filar guide and second filar guide.

After adopting such scheme, the present invention has many beneficial effects:

Directly or indirectly drive primary shaft and second rotation through servomotor among the present invention; And because meshed transmission gear between primary shaft and second; Make both direction of rotation; Final first filar guide and second filar guide realized staggers with opposite angles, changed the path and the tortuosity of yarn process like this, thereby changes the size of yarn tension.

Description of drawings

Fig. 1 is the structural representation of preferred embodiment of the present invention;

Fig. 2 is the scheme drawing that is electrically connected of preferred embodiment of the present invention.

The specific embodiment

In conjunction with accompanying drawing, preferred embodiment of the present invention is explained further details.

A kind of regulating control of automatically regulating yarn tension comprises tension detector 1, servomotor 2, primary shaft 3, second 4, first filar guide 5 and second filar guide 6.

The present invention adopts servomotor 2 to be because the servomotor rotation precision can electric accuracy control, helps controlling the precision that yarn tension changes.

Servomotor 2 drives primary shaft 3 through crowngear 21 and rotates, and first filar guide 5 is installed on the primary shaft 3, rotates along with the work of primary shaft 3.Primary shaft 3 and second 4 are through a pair of transmission gear 31 engaged transmission; Therefore second 4 rotation direction and primary shaft 3 form reversing sense; And second filar guide 6 is installed on second 4, can guarantee that therefore second filar guide 6 and first filar guide 5 are the reversing sense motion.Primary shaft 3, second spool 4 and are up and down and are in staggered distribution under parallel prerequisite, and this is in order to ensure spending rotation spaces for first filar guide 5 and second filar guide 360.

In order to prevent yarn pitch of the laps knotting, be provided with one in the middle of first filar guide 5 and second filar guide 6 and be installed in fixed stationary guide 7 on the equipment rack.Yarn when work, pass first filar guide 5, stationary guide 7 and second filar guide 6 successively, tension detector 1 is also passed through in final source.

Tension detector 1 itself is a maturing appts in field of textile machinery, is used to detect the tension force size of yarn.In the present invention; The detection signal of tension detector 1 is transported on the machine unit, unit 8, and single machine unit 8 converts through internal processes, draws a control signal; Be transported to the driven by servomotor 9 that is connected on its control end, remove to control the rotational angle of servomotor 2 by driven by servomotor 9.

When the present invention works,, produce signal and give single machine unit 8 when tension detector 1 detects yarn tension when too small; Single machine unit 8 drives servomotor 2 work through driven by servomotor 9; Thereby drive primary shaft 3, second 4 counter-rotation, therefore first filar guide 5 just forms counter-rotation with second filar guide 6 thereupon, and both angles become greatly; Increase yarn through stroke distances and tortuosity, made tension force become big automatically.Otherwise then first filar guide 5 and second filar guide, 6 angles diminish, and reduce yarn through stroke distances and tortuosity, finally reduce tension force.

The foregoing description only is used to the inventive concept of the present invention of explaining, but not to the qualification of rights protection of the present invention, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
