Example 2
FIG. 1 shows a simplified diagram of an armoring machine configuration; the device is driven by a 15KW alternating current asynchronous motor, and a large disc 6 is fixed with a main shaft 2 and can synchronously rotate along with the main shaft 2; 16 holes are uniformly distributed on the large disc 6 and used for mounting the FRP disc shaft 7; the front large plate 6 and the rear large plate 6 are equally divided into 4 FRP plates 4, the front FRP plate 4 and the rear FRP plate 4 are alternately distributed, and the effect picture is shown as 2; the pneumatic brake 9 controls the braking of the whole mechanism. The FRP belt releasing mode is passive belt releasing, namely the FRP disc 4 is dragged to rotate to passively release the wire through traction of a wire take-up device.
The working principle is as follows: the main shaft 2 is a hollow shaft processed by 20# cold drawing steel, so that the cable core can conveniently penetrate through an inner hole of the main shaft 2 and enter a subsequent yarn binding machine; as shown in fig. 3, the FRP tape passes through the guide wheel 11 of the guide wheel support 5 and the threading hole on the fixed support 1 (fig. 4) and enters the die on the subsequent equipment (yarn binding machine) to wrap the cable core. The FRP belt is rotationally wrapped on the outer layer of the cable core because the armoring machine is in rotation in the whole process. The tension of the FRP belt in the working process is manually adjusted through a tension wheel 8 (the machine is normally started again by manual adjustment of the process in the starting-up stage). Principle of tension adjustment (see FIG. 5)
The guide wheel 11 seat is composed of two half wheels and is fixed on the main shaft 2 by bolt tightening. The guide wheel 11 seat is equally divided into 8 guide wheels 11, porcelain sleeves are mounted at the wire inlet and outlet cutting openings of each guide wheel 11 for limiting, and the FRP belt is prevented from being scratched due to the fact that an inertia belt jumps out of an inner groove of the guide wheel 11 in the process of transition from high-speed belt release to low-speed belt release.
The fixed support 1 plays a main supporting role, supports two ends of the main shaft 2, and the main shaft 2 can easily rotate under the driving of the motor; the FRP belt enters the subsequent process through the porcelain bushing wire passing hole 10, and the FRP belt is in contact with the inner wall of the porcelain bushing to prevent the FRP belt from being scratched.
As can be seen from fig. 1-2, the whole path of the FRP tapes after coming out of the guide wheel 11 and entering the ceramic threading hole 10 of the support is gradually close to the center of the spindle 2 (the included angle between each FRP tape and the center line of the spindle 2 is about 30 °), and the FRP tapes are further close to the wrapping mold entering the subsequent process, so that all the FRP tapes to be contacted and the cable core are finally wrapped at the die of the yarn binding machine.
