Description

High-performance horizontal yarn carrying spindle for weaving fibers by braiding machine

Technical Field

The utility model relates to a horizontal spindle of taking of braider, especially a braider is used for weaving fibrous high performance horizontal spindle of taking.

Background

At present, when a plurality of braiding machines weave special materials, the adopted common yarn carrying spindles are vertically arranged on yarn tubes, the common yarn carrying spindles carry out cross motion on a track, the paying-off tension is controlled by springs, and due to the particularity of the braided fiber materials, the high performance requirements on the yarn carrying spindles are met, including controllability of the paying-off tension, large stroke and stability of the paying-off tension.

In fig. 4, a schematic diagram of a common carrier structure of the prior art is shown, which includes: 2-1 parts of spindle blade, 2-2 parts of bobbin, 2-3 parts of thread drop, 2-4 parts of bobbin shaft, 2-5 parts of middle porcelain eye, 2-6 parts of thread drop porcelain eye, 2-7 parts of outgoing line porcelain eye, 2-8 parts of brake pin shaft, 2-9 parts of brake pin shaft transverse shaft and 2-10 parts of flower disc.

A yarn bobbin shaft 2-4 is arranged on the spindle blade 2-1, the yarn bobbin 2-2 is sleeved on the yarn bobbin shaft 2-4, and one end of a thread drop 2-3 is sleeved on the spindle blade 2-1; a line drop porcelain eye 2-6 is arranged at the lower part of the spindle blade 2-1, a middle porcelain eye 2-5 is arranged at the middle part of the spindle blade 2-1, and a line outgoing porcelain eye 2-7 is arranged at the upper end of the spindle blade 2-1. During operation, yarns pass through the middle ceramic holes 2-5 of the spindle blade, are bent through the line drop ceramic holes 2-6 at the lower part of the spindle blade, and are paid off through the outgoing line ceramic holes 2-7 at the upper part of the spindle blade; during working, the yarn lifts the porcelain eye 2-6 of the line drop, the other end of the line drop 2-3 presses down the transverse shaft 2-9 of the brake pin shaft to enable the brake pin shaft 2-8 to slide downwards to be separated from the teeth 2-10 of the faceplate, and the bobbin 2-2 rotates to realize paying off and enable the bobbin to be circularly woven.

The bobbin can drive the sheath to move, so that the mandrel can be driven to move when the bobbin is paid off; the constant tension mechanism is connected with the mandrel and has the function of outputting constant torque, so that the mandrel obtains constant torque from the constant tension mechanism, and the yarn tube has constant paying-off tension in the paying-off process.

The utility model discloses a take spindle to move on the "8" word track of braider, because "8" word track has interior track and outer track, including on the track take spindle and outer track on can exist heterodyne in taking the spindle unwrapping wire, this inside and outside difference is called stroke unwrapping wire stroke difference, if unwrapping wire length on two tracks is different, will produce and take spindle braided wire on the track in do not have tension when weaving, at this moment, volute spiral spring device will play the effect. When the yarn carrying spindle is used for weaving, the bobbin is rotated for multiple circles according to the pretightening force direction of the spiral spring device, so that the bobbin has certain pretightening force, when the stroke of the yarn carrying spindle on the inner track is insufficient, the woven yarn has no tension, and at the moment, the spiral spring device can wind redundant yarn on the bobbin by the reverse force, so that the woven yarn is tensioned to generate tension.

When the spindle is taken to carry out yarn taking and weaving on the braiding machine by the high-performance horizontal bobbin, the spindle is taken to pay off uniformly and constantly by better enabling, the problem that the stroke tension of the spindle is taken by the inner rail and the outer rail is different is solved, a better product is braided by the braiding machine, and better cognition and development innovation of the spindle taking on the braiding machine are realized.

The problem of current take spindle when the preforming body is woven to the braider, unwrapping wire tension unstable, unwrapping wire tension uncontrollable, weave the stroke not enough is solved, reached the utility model discloses a purpose.

The advantages are that; the utility model discloses practiced thrift the manpower, improved quality, efficiency, guaranteed product stability, realized special braider long stroke, permanent tension, weave the pitch even.
