Abstract

The invention relates to a plied yarn tension resolution device. The plied yarn tension resolution device comprises a casing arranged on an overfeeding support, wherein a rotatable swing arm and a swing arm tension device are arranged in the casing; a yarn passing guide wheel is arranged on the swing arm; a micro-switch is arranged on the swinging path of the swing arm; the swing arm interacts with the micro-switch through a contact point. The plied yarn tension resolution device effectively avoids the severe consequence that single yarn proceeds upwards into a rolling zone, so as to ensure the plied yarn quality.

Description

A kind of strand tension force discriminating device

Technical field

The present invention relates to a kind of strand tension force discriminating device.

Background technology

In the rubber industry production processes such as automobile tire, conveyer belt, all to add its framework material.The framework material of rubber is generally polyamide fibre or terylene tyre cord.Bifilar cord fabric thread is in the past produced and is normally adopted two step method, first by single twisting, and then above-mentioned two strands or three strands of monofilament is carried out to composite twist, just becomes cord fabric thread.There is the shortcomings such as energy consumption is high, labor productivity is low, waste silk is many, row yielding is low in this mode of production, product lacks the market competitiveness.Along with further developing of science and technology, meet the tendency and produced novel one-step method twisting technology---directly twist technology, go up the outer silk of creel and through outer yarn tensioner, through spindle and internal thread in ingot tank, through interior yarn tensioner, together enter uniform twister and carry out retwist and become strand, then draw and export winding zone to and carry out coiling and molding through the defeated leno of overfeeding case.If have silk or fractured inner wire outside one in actual production process, will produce the consequence that monofilament is reeled, not only have a strong impact on product quality, and wasted raw material.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of when there is the situation of a rhizoid fracture, can cut off the strand tension force discriminating device that remaining yarn is braked spindle simultaneously.

For addressing the above problem, the technical solution used in the present invention is: a kind of strand tension force discriminating device, comprise the housing being arranged on overfeeding frame, in housing, be provided with one can turn swing arm and swing arm tensioner, on swing arm, be provided with wire carrier, on the swinging track of swing arm, be provided with microswitch, swing arm can have interaction with the trigger point of microswitch.

Described swing arm tensioner comprises a spring, and one end of spring is connected with swing arm, and the other end of spring is connected with housing.

On described housing, be fixed with nut, be provided with adjusting screw(rod) in nut, the other end of described spring is connected with adjusting screw(rod).

In described housing, be provided with mandrel, mandrel is outside equipped with rolling bearing, and described swing arm is connected with rolling bearing.

The invention has the beneficial effects as follows: owing to exporting overfeeding roller interval at uniform twister strand, strand tension force discriminating device has been installed, the strand that makes uniform twister output through above-mentioned cross wire carrier again to overfeeding roller, deflector roll around some circles after initiatively output.At inside and outside silk, do not have under disconnected state, strand has larger active force to crossing wire carrier, makes swing arm against the force of the spring and the bottom, and now swing arm hook portion does not act on microswitch trigger point, be that microswitch trigger point is ejection state, ingot position is normal twisting state.When inside and outside silk has broken any one, what uniform twister was exported is sub-thread silk, sub-thread silk to the active force of crossing wire carrier a little less than, be not enough to overcome above-mentioned spring tension, swing arm is lifted under the effect of spring force like this, swing arm hook portion is pressed into microswitch trigger point, output control signal, by the control of ingot level controller, impel the action of ingot positioning auxiliary device, cut off remaining yarn aerobraking simultaneously twisting spindle, effectively avoided being advanced on monofilament the generation of this serious consequence of winding zone, guaranteed strand quality.

Fig. 2 is internal structure schematic diagram of the present invention;

In figure: 1, overfeeding frame, 2, housing, 3, swing arm, 4, mandrel, 5, rolling bearing, 6, spring, 7, nut, 8, adjusting screw(rod), 9, cross wire carrier, 10, microswitch, 11, uniform twister, 12, overfeeding roller, 13, deflector roll.

The specific embodiment

Below by specific embodiment, a kind of strand tension force discriminating device of the present invention is described in further detail.

As shown in Figure 1 and Figure 2, a kind of strand tension force discriminating device, comprise the housing 2 being arranged on overfeeding frame 1, in housing 2, be provided with one can turn swing arm 3 and swing arm tensioner, in described housing 2, be provided with mandrel 4, mandrel 4 is outside equipped with rolling bearing 5, and described swing arm 3 is connected with rolling bearing 5.Described swing arm tensioner comprises a spring 6, and one end of spring 6 is connected with swing arm 3, on described housing 2, is fixed with nut 7, is provided with adjusting screw(rod) 8 in nut 7, and the other end of described spring 6 is connected with adjusting screw(rod) 8.On swing arm 3, be provided with wire carrier 9, and be provided with microswitch 10 on the swinging track of swing arm 3, swing arm 3 can have interaction with the trigger point of microswitch 10.

As shown in Figure 1, above-mentioned strand tension force discriminating device, in use, is arranged on housing 2 on overfeeding frame 1, and outer silk and internal thread are connected to overfeeding roller 12, deflector roll 13 after wire carrier 9 and initiatively export after around some circles by crossing of this device through uniform twister 11.At inside and outside silk, do not have under disconnected state, strand has larger active force to crossing wire carrier 9, makes swing arm 3 overcome spring 6 resistances and the bottom, and now swing arm 3 hook portions do not act on microswitch 10 trigger points, be that microswitch 10 trigger points are ejection state, ingot position is normal twisting state.When inside and outside silk has broken any one, what uniform twister 11 was exported is sub-thread silk, sub-thread silk to the active force of crossing wire carrier 9 a little less than, be not enough to overcome above-mentioned spring 6 pulling force, swing arm 3 is lifted under the effect of spring 6 power like this, swing arm 3 hook portions are pressed into microswitch 10 trigger points, output control signal, by the control of ingot level controller, impel the action of ingot positioning auxiliary device, cut off remaining yarn aerobraking simultaneously twisting spindle, effectively avoided being advanced on monofilament the generation of this serious consequence of winding zone, guaranteed strand quality.

The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not for limiting the present invention; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
