Wires and cables are usually made by three processes: drawing, twisting, and coating. By using flame-retardant cable steel strip coating equipment to coat the outside of the wires and cables with steel strips, the fire resistance and mechanical strength of the cables can be improved.

[0003] The existing cable steel belt is generally directly wound on the reel during production and transportation, and then installed on the coating equipment. The coating equipment drives the steel belt reel to rotate around the cable and loosens it from the outer end of the steel belt to complete the cable winding. During this process, the equipment needs to drive the steel belt reel as a whole to revolve around the outer circumference of the cable.

[0042] See also Figures 1-12 The present invention provides a coating method for a flame-retardant cable steel strip coating device, comprising the following steps:

[0043] S1. The steel strip 40 is wound to a position between the winding drum 4 and the side plate 5, and then the outer side of the steel strip 40 is limited;

[0044] S2. Remove the reel 4 and fit the side plate 5 and steel belt 40 onto the outer wall of the rotating drum 7. Secure the side plate 5. Pass the cable 39 through the center of the rotating drum 7 and the rubber sheathing machine 2. Then, connect the inner end of the steel belt 40 to the outer wall of the cable 39. Control the cable 39 to be transported at a constant speed.

[0045] S3. The rotating drum 7 is started to rotate, causing the steel belt 40 to rotate coaxially with the rotating drum 7. The steel belt 40 is loosened from the inside and wrapped around the outer wall of the cable 39 at the axis. This reduces the driving force required for the steel belt 40 to rotate and improves stability during operation. At the same time, the conveyor 8 performs hot pressing and shaping on the steel belt 40, causing one side of the steel belt 40 to bend inward. This improves the tightness of the steel belt 40 during the wrapping process and prevents the edges from turning outward.

[0046] S4. After the steel tape 40 is wrapped, the cable 39 is input into the rubber sleeve wrapping machine 2 for outer rubber sleeve wrapping to improve the winding stability of the steel tape 40 and prevent the steel tape 40 from loosening. Finally, the cable 39 is output and reeled.

[0047] When the first guide block 9 is engaged with the first guide block 9, the first guide block 9 and the guide block 10 are connected and fixed by the bolts 11 so that the spacing between the side plates 5 on both sides is just or slightly larger than the width of the steel strip 40. At this time, a winding drum capable of winding the steel strip 40 is formed. When in use, one end of the steel strip 40 is fixed by the first fixing clamp 12. Then, the steel strip 40 is wound between the two sets of side plates 5 on the outer wall of the winding drum 4. After the winding is completed, the sleeve ring 15 is sleeved on the outer walls of the two sets of side plates 5. By adjusting the position of the second fixing clamp 16 on the sleeve ring 15, the second fixing clamp 16 clamps the outer end of the steel strip 40 and fixes it. The threaded rings 17 are screwed on both sides of the sleeve ring 15. The threaded rings 17 on both sides are used to limit the side plates 5 on both sides, and subsequent transportation and use can be carried out.

[0048] The above-mentioned steel belt 40 is rolled up and transported as a whole to one end of the rotating drum 7, the conveyor 38 is removed, and the bolts 11 are unscrewed, and the first fixing clamp 12 is loosened to loosen the fixing of the inner side of the steel belt 40. At this time, the steel belt 40 as a whole will be stretched out to the surroundings due to the rebound force, reducing the resistance between the inner wall of the steel belt 40 and the outer wall of the winding drum 4. Thereafter, the winding drum 4 is pulled out from the inside of the side plate 5. The steel belt 40 will be limited between the side plate 5 and the sleeve ring 15. The guide frame 10 on the side plate 5 is inserted into the second guide block 19 from one end of the rotating drum 7, and the second outer gear ring 24 is adjusted. The position of the steel belt 40 is made to mesh with the second gear 27, and the guide frame 10 and the second guide block 19 are fixed by the bolts 11. Then the conveyor 38 and the cable 39 are installed, so that the cable 39 passes through the axis position of the rotating drum 7, and is output to the external winding device after passing through the rubber sleeve covering machine 2 for winding. One end of the inner side of the steel belt 40 is found from the operation port 18, and it is passed through the device frame 31. After passing through the position between the two sets of hot pressing grooves 34 and the driving wheel 37, the steel belt 40 at this end is fixed to the outer wall of the cable 39 to complete the preliminary installation operation.

[0049] Start the drive motor 21 to drive the first gear 22 to rotate, the first gear 22 drives the first outer gear ring 23 to rotate the rotating drum 7, control the cable 39 for one-way transportation, start the electric telescopic rod 32 to push the hot pressing blocks 33 on both sides to squeeze the steel belt 40 into the hot pressing groove 34 for hot pressing and shaping, control the drive wheel 37 to drive the steel belt 40 to transport at a uniform speed, so that the steel belt 40 is hot-pressed to a slightly bent state on the side facing the conveying direction of the cable 39, so that in the subsequent winding process, the edge of the steel belt 40 on the outside of the superimposed layer is folded inward and conflicts with the inner steel belt 40, thereby improving the winding stability and avoiding the edge of the steel belt 40 from turning outward and scratching the outer rubber sleeve.

[0050] The first gear 22 drives the first pulley 28, so that the transmission belt 30 drives the second pulley 29 to rotate. Since the radius of the first pulley 28 is larger than the radius of the second pulley 29, the rotation speed of the second pulley 29 is greater than the rotation speed of the first pulley 28 and the first gear 22. After the transmission through the connecting shaft 26, the rotation speed of the second gear 27 is greater than the rotation speed of the first gear 22. The second gear 27 drives the second outer gear ring 24, so that the sleeve ring 15 drives the outer end of the steel belt 40 to rotate, so that the steel belt 40 can rotate slightly faster than the rotating drum 7, ensuring that the inner end of the steel belt 40 can be continuously and stably transported inward to the outer wall of the cable 39 to complete winding during the rotation of the rotating drum 7. The rotation speed of the sleeve ring 15 is slightly greater than the rotation speed of the rotating drum 7, ensuring that the steel belt 40 will not get stuck during the continuous winding process. The speed control does not need to be too precise. It only needs to ensure that after the entire roll of steel belt 40 is wound, the steel belt 40 will not be tightly attached to the outer wall of the rotating drum 7 and cannot continue to be transmitted and transported.

[0051] The device changes the overall winding pattern of the steel belt 40 so that the steel belt 40 can be gradually loosened and output from the inside during the winding process, and the rotating drum 7 synchronously drives the steel belt 40 rolls to rotate at the same axial position, which greatly reduces the driving force required for the rotation of the steel belt 40. The center of gravity of the steel belt 40 changes less during the rotation, and the center of gravity change is greatly reduced compared with the traditional winding method of loosening the outside, which greatly reduces the energy required for the driving process. At the same time, the displacement of the steel belt 40 rolls is also reduced, which improves the stability of the equipment operation during the winding process. The cable 39 is transported and output stably in the middle to complete the covering operation of the steel belt 40. After the winding is completed, the side panel 5 and the socket ring 15 are removed to install a new steel belt 40 roll, which is convenient for disassembly and assembly.

[0052] It is worth noting that: during installation, multiple groups of steel belt 40 rolls can be continuously sleeved on the outer wall of the rotating drum 7, and only the side panels 5 on both sides of the outermost group of steel belt 40 rolls are fixed, and the remaining steel belt 40 rolls are supported and fixed by the supporting structure on the machine body 1, so that the rotating drum 7 only drives the outermost group of steel belt 40 rolls to rotate during the rotation process, and the rest remain fixed. When replacing, it is only necessary to remove the bolts 11 on the outer side panel 5, slide it out and support it, and then slide the adjacent group of steel belt 40 rolls and side panel 5 in the opposite direction to the position of the second guide block 19 for installation to improve replacement efficiency.
