Description

The wire rod feedway of medium-sized high-speed knitter

Technical field:

The utility model relates to a kind of wire rod feedway of medium-sized high-speed knitter, belongs to electric wire manufacturing equipment field.

Background technology:

Medium-sized high-speed knitter mainly is applicable to the weaving operation of shielding outer plexiform layers such as data communication cable, control cable, audio cable, also adapts to the cable of knit wire and yarn shuffling simultaneously.Braided wires is chosen in the scope of ￠ 0.08 ~ ￠ 0.18mm usually, knitting tension is regulated between 1N ~ 10N, the operate as normal speed of braiding machine is about 150 rev/mins, these characteristics require medium-sized high-speed knitter to provide knitting tension to regulate flexibly, thread-changing, threading time weak point, easy to operate, the wire rod feedway of compact conformation.There is following defective in existing medium-sized high-speed knitter wire rod feedway: knitting tension governor motion unreasonable structure, tension force are difficult for stable, the threading process is loaded down with trivial details, structure is not compact, the said structure defective effect wire ﹠ cable factory man scale produce produce efficient and product quality.

Summary of the invention:

By research to medium-sized high-speed knitter shielding outer plexiform layer weaving, analyzed the influence of main technologic parameters to the screen morphological feature, comprehensive above-mentioned result of study, the purpose of this utility model is the deficiency at the wire rod feedway of present use, tension adjustment and controlling organization are improved, optimized the parts of threading structure, provide that a kind of knitting tension is stable, the wire rod feedway of the medium-sized high-speed knitter of regulating flexible, easy to operate, compact conformation (being commonly called as: go up ingot, ingot down).

The utility model is achieved in that described tension adjustment and controlling organization be made up of major axis, support, support guide wheel, torsion spring, pinion, gear wheel, gear fixture block, fixture block torsion spring; Last ingot string-passing structure is made up of long porcelain tube, short porcelain tube, roller, horizontal porcelain tube; Following ingot string-passing structure is by porcelain tube, long wheel, fixedly porcelain tube, movable block, movable porcelain tube are formed.

The utility model is by the improvement to existing structure, can be good at satisfying the requirement of braided wires that medium-sized high-speed knitter is suitable for to knitting tension, and can guarantee the stability of tension force, it has the characteristics such as efficient of producing of weaving quality simple in structure, compact, easy to operate, as to regulate flexibly, help to improve product and large-scale production.

Fig. 2 is the ingot side-looking structural representation of going up of the present utility model.

Fig. 3 is an ingot plan structure schematic diagram down of the present utility model.

Fig. 4 is an ingot side-looking structural representation down of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4 the utility model is described in detail: tension adjustment and controlling organization be at braiding machine before braiding, carry out tension adjustment earlier according to different braided wires, when adjusting to predetermined tension force, fixture block with control tension force guarantees tension stability again, in the braiding process, if the degree of tightness situation of braided wires differs on the drum, braided wires will spur torsion spring by support, can adjust voluntarily, return to the state of predetermined tension, thereby guarantee the product quality of braiding.String-passing structure after the optimization has been simplified the threading process by rationally controlling of porcelain tube and roller, and is easy to operate.

Concrete condition is as follows, support guide wheel 1 is positioned at the top of support 2, support 2 is mounted and fixed on the centre of major axis 4, and torsion spring 3 is enclosed within on the major axis 4, and wherein an end of torsion spring 3 is wrapped on the support 2 fixing, the other end is enclosed within on the pinion 12 fixing, pinion 12 is installed in a side of major axis 4, and the rotation of pinion 12 realizes that by gear wheel 11 gear fixture block 9 is positioned at the below of gear wheel 11, rotate by fixture block torsion spring 10, the top of usual condition lower gear fixture block 9 is placed in the teeth groove of gear wheel 11.When needs were regulated knitting tension, handsetting gear fixture block 9 counterclockwise was separated from the teeth groove of gear wheel 11 fully up to the top of gear fixture block 9, and (clockwise direction rotates, and increases knitting tension slowly to rotate gear wheel 11 then; Counterclockwise rotate, reduce knitting tension), by Principles of Gear Connection driving pinion 12, drive the torsion spring 3 that is attached thereto and reverse, the size of knitting tension is determined by the support guide wheel 1 of dynamometer pulling support 2 tops.When adjusting to suitable knitting tension, unclamp gear fixture block 9 (utilizing pressure angle to reach self-locking), gear fixture block 9 turns round clockwise, and gear fixture block 9 tops are placed on again in the teeth groove of gear wheel 11, finish the process of the adjusting and the control of knitting tension like this.In case under the situation that the degree of tightness of appearance (braided wires is all formed by the merging of doubling equipment in advance by the multiply filament) braided wires differs, braided wires on support guide wheel 1 will spur support 2, torsion spring 3 cohesions or release moment tension force that traction is fixing with it, the tension force that carries out is among a small circle adjusted voluntarily, thereby has guaranteed the product weaving quality.

When last ingot carries out threading, braided wires is walked around support guide wheel 1, centre by the upright two long porcelain tubes 5 directly laying in the place ahead, be passed in roller 6 belows of front horizontal positioned, braided wires is passed by horizontal porcelain tube 7 tops of front again, by upright centre of directly laying two short porcelain tubes 8, finish the threading process of ingot at last.When ingot carries out threading instantly, braided wires is walked around support guide wheel 1, centre by upright two porcelain tubes 13 directly laying in the place ahead, pass from long wheel 14 belows of front horizontal positioned, after braided wires is passed through from fixedly porcelain tube 17 tops of front again, with the movable block 16 of fixing porcelain tube 17 tops be fixed on movable porcelain tube 15 on the movable block 16, be pressed into level, thereby finish down the threading process of ingot.Following ingot also is the engagement of pinion and gear wheel, pinion 12 ' with gear wheel 11 ' engagement, gear fixture block 9 ' be positioned at gear wheel 11 ' the below, gear fixture block and fixture block torsion spring 10 ' be connected.
