Description

A kind of double turntable braiding machine

technical field

The invention belongs to the technical field of textile machinery, in particular to a double-rotary disc braiding machine.

Background technique

At present, the more common weaving machine spindles mainly adopt the "Maypole" design principle, and the movement route of the spindles is sinusoidal. The spindle is contained on the shuttle, and a boat-shaped slide block and a cylindrical small shaft are made on the shuttle. The shuttle is moved by the cross-shaped groove of the sheave on the rotor to the small shaft on the shuttle, so that the boat-shaped slide block of the shuttle moves along the guide groove of the guide disc. When the boat-shaped slider of the shuttle passed the cross section of the guide groove, the small shaft of the shuttle was caught by the cross-shaped groove of the sheave on the other group of rotors, and the shuttle was moved to continue sliding. Due to the sliding friction between the spindle and the groove track, the spindle wears faster, the noise of the machine is larger, the running speed of the nail is low, and the service life is shorter. It is difficult for such a knitting machine to realize high-speed knitting.

There is also a RB-2 braiding machine, which drives the inner and outer spindles to rotate respectively by the inner and outer turntables. The reverse rotation of the internal and external turntables is realized through a complex planetary gear train, and the internal and external yarn weaving is realized through a cycloid mechanism, which can achieve a high weaving speed, but the structure is complicated and the manufacturing cost is high.

During the rotation process, the outer ring yarn passes through the yarn dividing disk and the yarn dividing rod, and passes through the inner ring yarn one by one to realize weaving.

The shape of the wire distribution plate is a combination of a large arc and a small arc, and a wire-stop protrusion protrudes from the end of the large arc. A sheave is installed on the thread distribution disc, and when the inner and outer rotary discs rotate, the pins on the wall of the outer turntable drive the sheave to rotate, thereby driving the thread distribution disc to rotate. It is required that when each outer ring yarn falls to the distribution disk, the distribution disk will turn N and a half circles. In this way, it is ensured that two adjacent outer ring yarns fall on the large arc and the small arc of the distribution disc respectively. When a certain outer ring yarn falls on the large-radius circular arc of the line distribution disc through the thread lifting rod, the outer ring yarn passes through the upper part of the inner ring yarn through the yarn splitting rod; when a certain outer ring yarn falls on the When on the small-radius circular arc of the line dividing disc, the outer ring yarn passes through the yarn dividing rod from the bottom of the inner ring yarn. The lifting rod is arc-shaped, and the center of the arc-shaped curvature radius of the lifting rod is on the same side as the center of the thread distribution disc. slide. The height of the wire lifting rod should exceed the highest point of the distribution plate.

The wheel train is used as the driving device of the double rotary disc knitting machine. When the bevel gear is driven to rotate, the two bevel gears are driven to rotate at the same speed and reverse, so as to drive the inner and outer rotating discs to rotate at the same speed and reverse.

The yarn carrier is placed on the second support roller fixed on the inner rotating disk. The first support roller on the yarn carrier is tangent to the second support roller. In this way, the inner turntable can drive the yarn carrier to rotate together. The outer ring yarn passing through the lower part of the inner ring yarn can pass through the tangent of the two rollers. The radial rollers are attached to the wall of the outer turntable to radially position the yarn carrier. The yarn dividing rod of the outer ring yarn is a device similar to a triangle. The outer ring yarn on the large circular arc of the distribution disc passes the inner ring yarn along the upper side of the yarn dividing rod; the outer ring yarn on the small circular arc of the distribution disc passes the inner ring yarn along the lower side of the yarn dividing rod.

The second supporting roller is a driving roller, which is driven to rotate by the transmission system, so that the outer ring yarn passes between the two rollers. Its transmission system includes a bevel gear set fixed on the outer turntable frame and a yarn carrier support roller gear train fixed on the inner turntable. When the two rotating disks rotate relative to each other, the bevel toothed disk and the carrier roller gear train mesh with each other and rotate, thereby driving the second supporting roller to rotate. The direction of the second supporting roller is the same as that of the outer ring yarn, and the speed is equal, so that the outer ring yarn can easily pass through the tangent of the two rollers.
