DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-6 As shown, a belt unwinding guide wheel mechanism for a half-cut high-speed steel belt armoring machine includes a belt unwinding guide wheel mechanism 3; the belt unwinding guide wheel mechanism 3 includes a guide wheel bracket 29, the guide wheel bracket 29 is rotatably equipped with a belt unwinding guide wheel 23, and the bottom of the guide wheel bracket 29 is connected to a cross plate 31 through a connecting rod 32; one end of the cross plate 31 is connected to a moving seat 25, the moving seat 25 is rotatably equipped with a bevel gear 28, one side of the cross plate 31 is rotatably connected to a worm 24, the outside of the worm 24 is in contact with the bevel gear 28, and the bottom of the connecting rod 32 is fixedly installed inside the bevel gear 28;

[0028] The end of the movable seat 25 is connected to the fixed seat 26, and the fixed seat 26 is fixedly connected to the rotating frame body 4. A slide groove 33 is arranged inside the fixed seat 26, and the slide groove 33 is arranged along the length direction of the rotating frame body 4. Both ends of the bottom of the movable seat 25 are connected to the fixed seat 26 through bolts and nut rods 27, and the bolts and nut rods 27 pass through the slide groove 33 and are connected to the fixed seat 26.

[0029] The guide wheel bracket 29 is rotatably mounted with the limiting wheels 22 on both sides above the unwinding guide wheel 23. The steel belt 19 passes through the tension control device 7 and the steering wheel assembly from the inside of the tape reel 6 and enters the inside of the unwinding guide wheel mechanism 3. Before the steel belt 19 contacts the unwinding guide wheel 23, it passes between the two limiting wheels 22 and is limited by the limiting wheels 22, making it more stable during movement.

[0030] Belt reels 6 are rotatably installed on both sides of one end of the rotating frame body 4, tape unwinding guide wheel mechanisms 3 are installed on both sides of one end of the rotating frame body 4, and tension control devices 7 are installed on both sides of the end of the rotating frame body 4 away from the tape unwinding guide wheel mechanism 3, and steering wheel assemblies are connected to the ends of the two sides of the rotating frame body 4 close to the tape unwinding guide wheel mechanism 3, and the steering wheel assembly and the tension control device 7 on the same side are arranged on the same side of the tape unwinding guide wheel mechanism 3.

[0031] The steering wheel assembly includes a seat plate 5, which is fixedly connected to the rotating frame 4, and a steering wheel 18 is rotatably installed on the same side of the top of the seat plate 5 and the top of the tension control device 7. The steering wheel 18 is on the same side as the tape unwinding guide wheel mechanism 3. After the steel belt 19 changes direction through the steering wheel 18, it can smoothly enter the interior of the guide wheel mechanism 3.

[0032] The specific steps of using the tape unwinding guide wheel mechanism include:

[0033] Step 1: If the wrapping angle of the steel belt 19 is 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;

[0034] Step 2: If the wrapping position of the steel belt 19 needs to be changed during the armoring process, 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 tape 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.

[0035] When the present invention is used, the cable core to be armored passes through 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 toward one end, and the rotating frame 4 rotates. 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;

[0036] When the steel belt 19 moves from the tape 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 over the upper part of the steering wheel 18 and enters the inside of the unwinding guide wheel mechanism 3, and is connected to the cable core after being guided by the unwinding guide wheel 23.

[0037] 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.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
