Description

Technical Field

[0001] This utility model relates to the field of cable armoring technology, and more specifically, it relates to a concentric armor wrapping machine with rapid feeding. Background Technology

[0002] The concentric armor wrapping machine is a high-precision device specifically designed for cable armor wrapping. It forms a robust armor layer by concentrically winding steel strips or other metal strips around the outer layer of the cable, providing protection and enhancing its mechanical strength. The machine's design ensures high precision in the armor wrapping effect and is typically equipped with an inner and outer roller system to ensure the steel strip is evenly and tightly wrapped around the cable surface. This system is particularly suitable for the production of high-strength cables, corrosion-resistant cables, and other cables with stringent armor layer requirements. It offers high efficiency and stability and is widely used in the power, electrical, and telecommunications industries.

[0003] However, traditional concentric armor wrapping machines typically use only one steel strip reel, which has certain limitations. Specifically, in such equipment, once the steel strip on a reel is armored, the operator needs to stop the machine, remove the used reel, and replace or rewrap a new one. This process not only wastes a lot of time but also leads to excessive downtime, significantly impacting production efficiency. Furthermore, the frequent removal and installation of the steel strip reel requires additional manual intervention, increasing operational complexity and equipment maintenance costs. Frequent reel replacements can also cause wear and tear on equipment components, shortening their lifespan and thus affecting the company's production plans and maintenance costs.

[0004] To improve production efficiency and reduce equipment downtime and maintenance costs, this application proposes a fast-feeding concentric armor wrapping machine. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a concentric armor wrapping machine with two sets of steel strip reels, both of which can be driven by the armor wrapping machine itself to wind the steel strip, and can achieve rapid feeding.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fast-feeding concentric armor wrapping machine includes a housing, and an armor assembly is provided inside the housing for armoring cables.

[0008] A feeding window is provided on one side of the outer shell, and a feeding assembly for feeding is provided on the feeding window. The feeding assembly includes a feeding roller arranged horizontally, and two sets of feeding rotating shafts are sleeved on the feeding roller at intervals.

[0009] The armor assembly includes an outer disc drive and an inner disc drive. The outer disc drive is connected to an outer disc drive roller via a transmission device. An outer steel strip reel is rotatably connected to the end of the outer disc drive roller away from the outer disc drive. The inner disc drive is connected to an inner disc drive roller via a transmission device. An inner steel strip reel is rotatably connected to the end of the inner disc drive roller away from the inner disc drive. A wrapping disc is coaxially arranged on the inner disc drive and the inner steel strip reel. The wrapping disc is connected to a wrapping disc drive via a transmission device.

[0010] The present invention is further configured such that: a slide rail is provided on the side of the outer shell away from the loading window, a sliding door is slidably connected on the slide rail, and a set of through holes are respectively opened on both sides of the outer shell, and the through holes are coaxially arranged with the armor assembly.

[0011] The present invention is further configured such that the outer disk drive roller and the inner disk drive roller are hollow cylindrical structures, and the outer disk drive roller passes through the interior of the inner disk drive roller.

[0012] The present invention is further configured such that: the wrapping disc includes a chassis arranged in a vertical direction, the chassis is configured as a hollow disc structure, the chassis is provided with a number of fixed columns around the center, and a set of fixed plates are respectively arranged at symmetrical positions on both sides of the chassis, and side wheels are connected to the fixed plates.

[0013] The present invention is further configured such that: a mating plate is connected to the end of the fixing column away from the chassis; a wire hole is provided at the center of the mating plate; two sets of inner rotating wheels are connected to the mating plate; the inner rotating wheels are inclined; and an outer rotating wheel is provided on the outer side of each set of inner rotating wheels; the outer rotating wheel is positioned perpendicular to the mating plate.

[0014] The present invention is further configured such that: two sets of mounting grooves are provided on the mating plate, the two sets of mounting grooves are symmetrically arranged along the center of the wire hole, and the inner rotating wheel includes a connecting plate slidably connected to the mounting groove, thereby realizing the relative movement of the mating plate position through the connecting plate.

[0015] In summary, this application offers the following beneficial technical effects: This application achieves efficient and precise cable armoring through a double steel strip reel design. The steel strip reels do not require disassembly and can be directly fed via the feeding assembly, avoiding frequent disassembly and installation, reducing equipment power consumption and wear, and shortening armoring time. The feeding system, through the precise coordination of the feeding roller and feeding shaft, ensures that the steel strip enters the armoring area smoothly and efficiently, avoiding jamming and delays, and improving production efficiency. Simultaneously, during armoring, the distance between the inner and outer rollers can be flexibly adjusted to regulate the tightness of the armor layer and the winding method, adapting to cables of different specifications and materials, meeting diverse armoring needs, and ensuring optimal armoring results. The cooperation of the inner and outer rollers allows the cable to pass smoothly through the winding area of ​​the armoring machine, preventing cable damage or loosening. Precise adjustment effectively improves the quality of the armored product and is suitable for armoring various cable specifications. Attached Figure Description

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] Example 1, please refer to Figures 1-7 The present invention provides the following technical solution:

[0030] Specifically, it refers to a concentric armor wrapping machine with rapid feeding; see [link / reference]. Figure 1 A fast-feeding concentric armor wrapping machine includes a housing 1, and an armor assembly 2 is provided inside the housing 1. The armor assembly 2 is used to armor the cable.

[0031] Please see Figure 1 , Figure 2 The outer casing 1 has a feeding window 14 on one side, and a feeding assembly 15 for feeding is provided on the feeding window 14. The feeding assembly 15 includes a feeding roller 151 arranged horizontally, and two sets of feeding rotating shafts 152 are sleeved on the feeding roller 151 at intervals. The two sets of feeding rotating shafts 152 correspond to the positions of the outer steel strip reel 24 and the inner steel strip reel 23. When feeding is required, the steel strip can be fed through the cooperation of the feeding rotating shafts 152.

[0032] Specifically, when all the steel strips on the outer steel strip reel 24 and the inner steel strip reel 23 are exhausted, the operator winds the two sets of steel strips onto the outer steel strip reel 24 and the inner steel strip reel 23 respectively, and then places the steel strips on the feeding shaft 152. The outer disc drive 21 and the inner disc drive 22 rotate in opposite directions (opposite to the rotation direction during armoring), thereby realizing the feeding of steel strips.

[0033] Please see Figure 1To facilitate operation and maintenance, a slide rail 13 is provided on the side of the outer casing 1 away from the loading window 14, and a sliding door 11 is slidably connected to the slide rail 13. Through the sliding door 11, operators can easily observe the armoring effect of the armor assembly 2, ensuring visual monitoring of the production process. When the armor assembly 2 requires maintenance or malfunctions, the design of the sliding door 11 provides a convenient maintenance channel, making equipment maintenance more efficient and convenient. A set of through holes 12 are respectively opened on opposite sides of the outer casing 1, and the through holes 12 are coaxially arranged with the armor assembly 2. Cables enter the armor assembly 2 through the through hole 12 on one side, and after armoring is completed on the armor assembly 2, they exit through the through hole 12 on the other side.

[0034] See Figures 3-7 The armor assembly 2 includes an outer disc drive 21 and an inner disc drive 22. The outer disc drive 21 is connected to an outer disc drive roller 211 via a transmission device. An outer steel strip disc 24 is fixedly connected to the end of the outer disc drive roller 211 away from the outer disc drive 21. The outer disc drive 21 drives the outer disc drive roller 211, which in turn drives the outer steel strip disc 24 to rotate. The inner disc drive 22 is connected to an inner disc drive roller 221 via a transmission device. An inner steel strip disc 23 is fixedly connected to the end of the inner disc drive roller 221 away from the inner disc drive 22. A wrapping disc 26 is coaxially arranged between the inner disc drive 22 and the inner steel strip disc 23 and is located inside the wrapping disc 26. The wrapping disc 26 is connected to a wrapping disc drive 25 via a transmission device. The wrapping disc drive 25 provides power to the wrapping disc 26 to achieve armoring. In this embodiment, the transmission devices of the inner disc drive 22 and the inner disc drive roller 221, the transmission devices of the outer disc drive 21 and the outer disc drive roller 211, and the transmission devices of the wrapping disc drive 25 and the wrapping disc 26 are all configured as belt drives.

[0035] It should be noted that the armor assembly 2 is fixedly installed inside the outer shell 1, and the outer shell 1 has a groove that matches the shape of the armor assembly 2. A cylindrical fixing block is fitted on the end of the outer disc drive roller 211 away from the outer steel strip disc 24, and the cylindrical fixing block matches the shape of the groove inside the outer shell 1.

[0036] Specifically, during the cable armoring process, after all the steel strips on the inner steel strip reel 23 have been used up, the outer steel strip reel 24 is used to continue the armoring, making the armoring process more continuous and stable, and avoiding the interruption caused by changing the steel strip reel in traditional equipment.

[0037] It should be noted that both the inner disc drive 22 and the outer disc drive 21 are activated when feeding steel strips. After all the steel strips on the inner steel strip reel 23 and the outer steel strip reel 24 have been used, the operator places the two sets of steel strips on the feeding shaft 152 through the feeding window 14 and then winds them onto the inner steel strip reel 23 and the outer steel strip reel 24. Then, the inner disc drive 22 and the outer disc drive 21 are activated to rotate the inner steel strip reel 23 and the outer steel strip reel 24, thereby completing the feeding. This process does not require disassembling the inner steel strip reel 23 and the outer steel strip reel 24, saving time and avoiding damage during the disassembly and handling of the steel strip reels.

[0038] See Figure 4 The outer disk drive roller 211 and the inner disk drive roller 221 are configured as hollow cylindrical structures. The outer disk drive roller 211 passes through the inner disk drive roller 221, and the central cylindrical cavity of the outer disk drive roller 211 is used for passing cables.

[0039] The wrapping disc 26 includes a base 261 arranged vertically. The base 261 is a hollow disc structure. Several sets of fixing posts 2611 are arranged around the center of the base 261. The fixing posts 2611 are arranged perpendicular to the wrapping disc 26. A set of fixing plates 2612 are arranged symmetrically on both sides of the base 261. The fixing plates 2612 are arranged perpendicular to the base 261. Side wheels 2613 are connected to the fixing plates 2612.

[0040] The end of the fixing post 2611 furthest from the chassis 261 is connected to a mating plate 262. The mating plate 262 consists of a ring and an irregularly shaped plate, with a wire-passing hole 263 in the center for passing cables. Two sets of inner rotating wheels 264 are mounted on the mating plate 262, each set of inner rotating wheels 264 being inclined to accommodate different armoring angles and cable characteristics. A set of outer rotating wheels 265 is provided outside the inner rotating wheels 264, with the outer rotating wheels 265 perpendicular to the mating plate 262, serving to guide and clamp the armored cables, ensuring stability and precision during the armoring process.

[0041] Two sets of mounting slots 267 are provided on the mating plate 262, and the mounting slots 267 are arranged symmetrically along the center line of the wire-passing hole 263. Each set of inner rotating wheels 264 is slidably connected in the mounting slot 267, and the connecting plate 2621 realizes the relative movement of the inner rotating wheels 264. By adjusting the position of the connecting plate 2621, the distance between the inner rotating wheel 264 and the outer rotating wheel 265 can be flexibly changed, thereby adjusting the tightness of the armor layer and the winding method. This can adapt to cables of different specifications and materials, meet diverse armoring needs, and ensure that the armoring effect reaches the optimal state. The cooperation of the inner and outer rotating wheels allows the cable to pass smoothly through the winding area of ​​the armoring machine, avoiding damage or loosening of the cable. Through precise adjustment, the quality of the armored product can be effectively improved, and it is suitable for armoring various specifications of cables.

[0042] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
