[0025] Beneficial effects of the present invention:

[0026] 1. By installing a tension control device on the outside of the rotating frame, the tension of the steel belt can be changed during the armoring process. Turn the adjusting screw to move in the horizontal direction, thereby driving the swing arm to rotate around the swing arm shaft at the bottom. The swing arm rotates to the side away from the spring bracket, driving the upper steering wheel away from the spring bracket, thereby increasing the tension of the steel belt; the swing arm rotates to the side of the spring bracket, driving the upper steering wheel close to the spring bracket, thereby reducing the tension of the steel belt.

[0027] 2. By installing a tape unwinding guide wheel mechanism on the outside of the rotating frame, if the wrapping angle and wrapping position of the steel belt are to be changed during the armoring process, the angle between the tape unwinding guide wheel and the cable core and the horizontal position of the tape unwinding guide wheel on the fixed seat can be adjusted. When changing the wrapping angle, the worm on one side of the horizontal plate is rotated, and the worm drives the internal bevel gear to rotate, and then drives the connecting rod to rotate, thereby driving the upper guide wheel bracket and the tape unwinding guide wheel to rotate and change the angle. The angle between the tape unwinding guide wheel and the cable core is changed, and the wrapping angle between the steel belt and the cable core is changed. When changing the wrapping position, loosen the bolts and nuts at both ends of the moving seat, push the moving seat to move along the slide groove on one side of the fixed seat, and then drive the guide wheel bracket and the tape unwinding guide wheel on the fixed seat to change their positions, so that the wrapping position between the steel belt and the cable core is changed. The angle and position of the tape wrapping can be adjusted by twisting the worm and the bolt and nut rod. The adjustment is convenient and quick, and the adjustment accuracy is high. The angle and position of the tape wrapping are more accurate, and the wrapping effect is better.

[0028] 3. By connecting the brake disc and the mounting frame as one, when the armoring stops, the drive motor stops rotating, the brake caliper contacts the brake disc, and the friction of the brake disc is increased, so that the rotating frame can stop rotating faster. The brake disc and the rotating frame are connected as one, and the braking effect is better. The rotating frame is welded with an integral rectangular steel plate, and both ends of the rotating frame are fixed with support shafts, so that the strength and stability of the rotating frame are improved and can adapt to higher speeds. The speed can be increased from 300r / min to 450r / min, and the working efficiency of the armoring is greatly improved.

[0048] The unwinding guide wheel mechanism 3 includes a guide wheel bracket 29, inside which the unwinding guide wheel 23 is rotatably installed, and the guide wheel bracket 29 is rotatably installed with limit wheels 22 on both sides above the unwinding guide wheel 23, and the bottom of the guide wheel bracket 29 is connected to the cross plate 31 through a connecting rod 32.

[0049] One end of the horizontal plate 31 is connected to a moving seat 25, and a bevel gear 28 is rotatably installed inside the moving seat 25. One side of the horizontal plate 31 is rotatably connected to a worm 24, and the outside of the worm 24 abuts against the bevel gear 28.

The brake caliper 35 rotates inside the force-bearing frame and abuts against the brake disc 12, thereby increasing the friction of the brake disc 12, thereby allowing the rotating frame body 4 to stop rotating quickly.

[0052] The specific steps of using this high-speed steel strip armoring machine include:

[0053] Step 1: The cable core to be armored passes through the top two ends of the base 1, the first support shaft 9, the second support shaft 10 and the rotating frame 4, and one end of the steel belt 19 inside the belt drum 6 is connected to the outside of the cable core; during the armoring process, the external machinery pulls the cable core to move horizontally to one end, and the driving motor 2 drives the rotating frame 4 to rotate; the steel belt 19 is wound around the outside of the cable core as the rotating frame 4 rotates;

[0054] Step 2: If the tension of the steel belt 19 is to be changed during the armoring process, the adjusting screw 15 is twisted to move in the horizontal direction, thereby driving the swing arm 14 to rotate around the swing arm shaft 36 at the bottom; the swing arm 14 rotates to the side away from the spring bracket 17, driving the upper steering wheel 18 away from the spring bracket 17, thereby increasing the tension of the steel belt 19; the swing arm 14 rotates to the side of the spring bracket 17, driving the upper steering wheel 18 close to the spring bracket 17, thereby reducing the tension of the steel belt 19; after the adjusting screw 15 is twisted and moved, the compression amount of the tension spring 16 outside the adjusting screw 15 changes, thereby adjusting the tension tightness of the tension belt 30, thereby adjusting the tension of the steel belt 19;

[0055] Step 3: If the wrapping angle of the steel belt 19 needs to be changed during the armoring process, the worm 24 on one side of the cross plate 31 is rotated, and the worm 24 drives the internal bevel gear 28 to rotate, and then drives the connecting rod 32 to rotate, thereby driving the upper guide wheel bracket 29 and the unwinding guide wheel 23 to rotate and change the angle; the angle between the unwinding guide wheel 23 and the cable core is changed, and the wrapping angle between the steel belt 19 and the cable core is changed; if the wrapping position of the steel belt 19 needs to be changed, loosen the bolt and nut rods 27 at both ends of the movable seat 25, and push the movable seat 25 to move along the slide groove 33 on one side of the fixed seat 26, thereby driving the guide wheel bracket 29 and the unwinding guide wheel 23 on the fixed seat 26 to change their positions, thereby changing the wrapping position between the steel belt 19 and the cable core.

[0056] When the present invention is in use, the cable core to be armored is passed through the top two ends of the base 1, the first support shaft 9, the second support shaft 10 and the rotating frame 4, and one end of the steel belt 19 inside the belt reel 6 is connected to the outside of the cable core. During the armoring process, the external machinery pulls the cable core to move horizontally to one end, and the driving motor 2 drives the rotating frame 4 to rotate through the transmission synchronous belt 8. The steel belt 19 is wound around the outside of the cable core as the rotating frame 4 rotates, and the cable core moves evenly horizontally, so that the steel belt 19 is evenly wound around the outside of the cable core;

[0057] During the movement of the steel belt 19 from the belt drum 6 to the cable core, it passes through the tension control device 7, the steering wheel 18 and the unwinding guide wheel mechanism 3 in sequence. The steel belt 19 passes through the upper part of the steering wheel 18 on the side of the swing arm 14 and the seat plate 5 and enters the interior of the unwinding guide wheel mechanism 3, and is connected to the cable core after being guided by the unwinding guide wheel 23.

[0058] If the tension of the steel belt 19 is to be changed during the armoring process, the adjusting screw 15 is turned to move in the horizontal direction, thereby driving the swing arm 14 to rotate around the swing arm shaft 36 at the bottom. The swing arm 14 rotates to the side away from the spring bracket 17, driving the upper steering wheel 18 away from the spring bracket 17, thereby increasing the tension of the steel belt 19; the swing arm 14 rotates to the side of the spring bracket 17, driving the upper steering wheel 18 close to the spring bracket 17, thereby reducing the tension of the steel belt 19. After the adjusting screw 15 is turned to move, the compression amount of the tension spring 16 outside the adjusting screw 15 changes, and then the tension tightness of the tension belt 30 is adjusted, so that the tension of the steel belt 19 is adjusted. The tension of the steel belt 19 can be adjusted by turning the adjusting screw 15, and the tension of the steel belt 19 in the armor is constant, so that the tension adjustment of the steel belt 19 is convenient and fast, simple to operate, and high work efficiency.

[0059] If the wrapping angle and wrapping position of the steel belt 19 are to be changed during the armoring process, the angle between the unwinding guide wheel 23 and the cable core and the horizontal position of the unwinding guide wheel 23 on the fixed seat 26 can be adjusted. When changing the wrapping angle, the worm 24 on one side of the cross plate 31 is rotated, and the worm 24 drives the internal bevel gear 28 to rotate, and then drives the connecting rod 32 to rotate, thereby driving the upper guide wheel bracket 29 and the unwinding guide wheel 23 to rotate and change the angle. The angle between the unwinding guide wheel 23 and the cable core is changed, and the wrapping angle between the steel belt 19 and the cable core is changed. When changing the wrapping position, loosen the bolt nut rod 27 at both ends of the moving seat 25, push the moving seat 25 to move along the slide groove 33 on one side of the fixed seat 26, and then drive the guide wheel bracket 29 and the unwinding guide wheel 23 on the fixed seat 26 to change their positions, so that the wrapping position between the steel belt 19 and the cable core is changed. The angle and position of the wrapping tape can be adjusted by twisting the worm 24 and the bolt nut rod 27. The adjustment is convenient and quick, and the adjustment accuracy is high. The angle and position of the wrapping tape are more accurate, and the wrapping tape effect is better.

[0060] When the armoring is stopped, the driving motor 2 stops rotating, and the cylinder 34 runs, pushing the brake calipers 35 on both sides to abut against the brake disc 12, thereby increasing the friction of the brake disc 12, so that the rotating frame 4 can stop rotating faster. The brake disc 12 is connected to the rotating frame 4 as a whole, and the braking effect is better. The rotating frame 4 is welded with an integral rectangular steel plate, and both ends of the rotating frame 4 are fixed with support shafts, so that the strength and stability of the rotating frame 4 are improved, and it can adapt to higher rotation speeds. The rotation speed can be increased from 300r / min to 450r / min, and the working efficiency of the armoring is greatly improved. The overall equipment is not easy to be damaged and has good safety performance.
