In the existing plastic circular weaving machine, a track for the shuttle to make circular motion is generally formed by a door ring assembly, for example, a roller is arranged between an upper door ring and a lower door ring, the roller is distributed along the circumferential direction of the door ring and forms a rolling track, and the shuttle runs on the rolling track. Because the weaving speed of the circular weaving machine is high, the shuttle can run for 150-200 revolutions per minute, and the impact generated when the shuttle bottom plate of the shuttle is contacted with the track is very serious, one of the shuttle bottom plate and the rolling track is made of steel, and the other one is made of damping material, so that the running reliability is ensured, and the impact is reduced. For example, the rollers of a plastic circular loom are made of rubber or polyurethane, and the shuttle plate is made of aluminum alloy. Because the diameter ratio of gyro wheel is less, consequently the rotational speed of gyro wheel after being driven by the shuttle can more accelerate, and the result will lead to the shock attenuation material wearing and tearing on the gyro wheel very severe, needs often to change, and braided bag manufacturing enterprise's use cost is higher.

Detailed Description

The utility model provides a shuttle, as shown in fig. 1 to 3, including the shuttle 1, the front of shuttle 1 is equipped with the mounting bracket 11 that is used for installing the woof spindle, the back mounting of shuttle 1 has wear-resisting shuttle bottom plate 2, shuttle bottom plate 2's the back is equipped with friction surface 21 along length direction, shuttle bottom plate 2 is connected fixedly through first screw 3 and shuttle 1, shuttle bottom plate 2's the back is equipped with heavy groove 22, be equipped with layering 4 in the heavy groove 22, layering 4 is connected with shuttle 1 through second screw 5 and compresses tightly shuttle bottom plate 2, friction surface 21 centers on the periphery of heavy groove 22, first screw 3, second screw 5 and layering 4 all are less than friction surface 21.

The utility model discloses in, shuttle bottom plate 2 adopts wear-resisting material to make on the back installation shuttle body 1 alone, form orbital gyro wheel or roller of rolling and can adopt steel to make, the problem of gyro wheel need be changed because of wearing and tearing has been solved, because the speed of shuttle operation will be much slower than the rotation speed of gyro wheel, the shuttle simultaneously can contact with a plurality of gyro wheels in the operation process, in unit interval, the total area of 2 contact rollers of shuttle bottom plate will be much greater than single gyro wheel contact shuttle bottom plate 2's area, consequently, the effect that bears the impact through shuttle bottom plate 2 will be much better, this also makes shuttle bottom plate 2's life will be longer than the gyro wheel among the prior art, make shuttle bottom plate 2's use cost will be much lower, thereby can reduce the cost of braided bag manufacturing enterprise. In order to reliably fix the shuttle base plate 2 on the shuttle body 1, the pressing strip 4 is designed to press the shuttle base plate 2 besides directly adopting the first screw 3 for connection, the pressing effect is better because the contact area of the pressing strip 4 and the shuttle base plate 2 is large enough, and meanwhile, the friction surface 21 surrounds the periphery of the sunk groove 22, namely the pressing strip 4 is positioned in the central area of the back surface of the shuttle body 1, so that the fixing effect on the whole shuttle base plate 2 is better. The first screw 3, the second screw 5 and the pressing strip 4 are all lower than the friction surface 21, so that the influence on the normal operation of the shuttle caused by collision with the roller after the protrusions are avoided.

In the present invention, fig. 3 can be referred to for the front end and the rear end of the shuttle, and the left end is the front end and the right end is the rear end in fig. 3. In the embodiment shown in the drawings, the shuttle body 1 is provided with a shuttle wheel 13. In some types of circular knitting machines, the shuttle 1 may not be provided with a shuttle wheel.

In order to reduce the influence of the arrangement of the first screw 3 on the friction surface 21, a screw counter bore 23 can be arranged on the shuttle bottom plate 2 at the edge of the friction surface 21, and the first screw 3 passes through the screw counter bore 23 to be connected with the shuttle body 1. And particularly in the embodiment, the first screws 3 can be designed to be distributed on the front end edge and the rear end edge of the shuttle base plate 2.

Since the shuttle base plate 2 is subjected to impact for a long time, through holes 24 for preventing stress concentration may be provided at both front and rear ends of the sink groove 22 in order to improve the service life.

In addition, in order to facilitate the processing and forming of the shuttle body 1, the mounting frame 11 can be detachably connected to the shuttle body 1, meanwhile, the structure of the through hole 24 is utilized, the mounting through hole 12 is formed in the back face of the shuttle body 1, the mounting through hole 12 is aligned with the through hole 24, and a fastening screw penetrates through the mounting through hole 12 to be connected with the mounting frame 11 to fix the mounting frame 11.

Because the shuttle moves forwards, the front end of the shuttle bottom plate 2 bears the largest impact, so in order to improve the reliability of the front end fixing of the shuttle bottom plate 2, a screw counter bore 23 is distributed on the front side of the through hole 24 on the shuttle bottom plate 2, and a first screw 3 is added at the position.

To ensure that there is a sufficiently large friction surface 21 in contact with the roller, the width B2 of the presser bar 4 may be controlled not to exceed 1/3 of the width B1 of the shuttle base plate 2.
