The tension self-adjusting device comprises a rotary arm, a turning wheel and a main shaft, wherein the rotary arm is driven by the main shaft to do rotation motion, and the turning wheel is assembled on the rotary arm through a hinge pin, connected with the rotary arm through a spring and moves in a slotted hole of the rotary arm. The tension self-adjusting device is simple in structure and stably and reliably operates, so that the tension of each strand of wire in a rope can be automatically adjusted and uniform accordingly.

Description

A kind of tension force self-adjusting apparatus of crank closer

Technical field

The utility model belongs to the netting technical field of processing equipment, especially relates to a kind of tension force self-adjusting apparatus of crank closer.

Background technology

Crank closer is becoming a burst priority with fiber twisting, once twist just again after three strands or four strands of strands will merge and to become rope, yet the factor due to mechanism and technique etc., tension force between three strands or four strands of strands is difficult to reach consistent, thereby cause the existence of finished product rope residual tensions, make rope occur even significantly to jump the phenomenons such as thigh from curling or distortion, in addition, existence due to residual tensions, the powerful obviously decline that rope can bear, elongation at break diminishes, and the elasticity variation of rope has greatly affected the mechanical property of rope.Therefore, in the control of tension force in the rope process, particularly three stranded rope process, between different strands, the control of tension force becomes the key that guarantees product quality.Yet the present crank closer major part of using does not all have tension-adjusting gear, so just is difficult to guarantee the quality of product.There is tension-adjusting gear in equipment component, but most of the adjusting is all in yarn stage, by applying tension ring isostension mechanism, guarantee that unwinding yarn out has relatively consistent tension force, although can play the purpose of stable tension preferably, but can not avoid the irregular generation of tension force in subsequent technique, so, the method has improved uniform tension in order to a certain extent, but can not eliminate to produce the irregular essential reason of tension force.Also have by methods such as heat treatments and realize tension adjustment, the method is a kind of follow-up adjusting, after being the irregular generation of tension force, hot property according to fiber product, by heat treatment, make tension force be released to a certain extent, although it is irregular to alleviate tension force, improve the mechanical and physical performance of rope and the surface property of rope, but can not eliminate tension force.The irregular key factor that affects product quality that becomes of tension force between different piece.

Summary of the invention

The purpose of this utility model is: the tension force self-adjusting apparatus that a kind of tension adjustment crank closer even, simple in structure is provided.

The technical solution of the utility model is: comprise pivoted arm, runner, main shaft, pivoted arm is connected with main shaft, and rotatablely moves under the drive of main shaft, and runner is assembled on pivoted arm by bearing pin, be connected by spring between runner and pivoted arm, be moved in the slotted eye of runner in pivoted arm.

the beneficial effects of the utility model are: runner can move up and down under the adjusting of spring within the specific limits, become every strand of rope separately through after the runner on a pivoted arm, rotate with pivoted arm, circular motion occurs, when strand tension force is large, strand can apply a large pressure to runner, runner can move to the pivoted arm center under the adjusting of spring, the rotating centrifugal radius of strand reduces, rope is lax, tension force reduces, equally, when strand tension force hour, runner can be under the adjusting of spring, locate mobile outside the pivoted arm center, centrifugal radius increases, the rope tensioning, tension force increases, adjusting by spring like this, the change of the centrifugal radius of pivoted arm, automatically regulate the tension force on balanced strand.The utility model can be regulated in rope the tension force in every strand automatically, thereby make every to become the tension force in the rope strand line to reach even, and make the tension value between each root strand reach substantially equal, thereby improve the tensile break strength of final products, increase the use safety coefficient of rope, reduce percent defective, save cost.Have simultaneously following characteristics: (1) makes adjustment process to change continuously, the tension variation good stability due to the device that adopts spring as adjustment stroke; (2) carrying out tension adjustment on pivoted arm, is a kind of real-time adjusting, has fundamentally stopped the irregular generation of tension force, and regulating effect is good; (3) simple in structure, running is reliable and stable, simple to operate, cost is lower, is applicable to the adjusting of the strand tension force of three strands and multiply torsade, can be used in conjunction with presently used crank closer.

The specific embodiment

Can find out from the left view of structural representation of the present utility model shown in Figure 1, Fig. 2, the profile of Fig. 3 pivoted arm part, the utility model comprises spring 1, runner 2, bearing pin 3, pivoted arm 4, main shaft 5 and other accessory.Pivoted arm 4 is connected with main shaft 5, and pivoted arm 4 rotatablely moves under the effect of main shaft 5, and runner 2 is assembled on pivoted arm 4 by bearing pin 3, is connected by spring 1 between runner 2 and pivoted arm 4 ends, is moved in the slotted eye 6 of runner 2 in pivoted arm 4.Range of movement and direction are regulated by spring 1, and spring 1 arranges at the both sides of runner 2 Parallel Symmetric, and the strand process is arranged on runner 2.

The utility model designs for the tension force of better regulating strand in torsade, and the centrifugal radius when regulating the strand rotation reaches the purpose of automatic adjusting strand tension force.Its operation principle is: strand is made circular motion with pivoted arm 4 after runner 2, and pivoted arm 4 is driven by main shaft 5, and spring 1 is just regulated moving up and down of runner 2 according to the tension force of strand, and when strand tension force was large, runner 2 was to pivoted arm 4 central motions, and strand is lax; Strand tension force hour, runner 2 outwards moves along pivoted arm 4, the strand tensioning.
