Description

Technical Field

[0001] This utility model relates to the field of insulated cable production technology, specifically to an integrated bonding and pressing molding device for the water-blocking layer and the insulation layer of an insulated cable. Background Technology

[0002] In the production of insulated cables, the tight bonding between the water-blocking layer and the insulation layer directly determines the cable's water-blocking performance and insulation reliability.

[0003] The existing molding equipment has obvious shortcomings: the water-blocking tape winding relies on simple mechanisms or manual assistance, lacks precise positioning and synchronous drive structure, and is prone to uneven winding and interlayer gaps, resulting in water-blocking failure; the pressing rollers are mostly single-drive or have poor groove adaptability, which can easily lead to loose bonding due to asynchronous pressing and size mismatch, resulting in unstable molding quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated bonding and pressing molding device for the water-blocking layer and the insulation layer of insulated cables. This solves the problems of water-blocking tape winding relying on simple mechanisms or manual assistance, lacking precise positioning and synchronous drive structures, which easily leads to uneven winding, interlayer gaps, and water-blocking failure. Furthermore, pressing rollers are mostly single-drive or have poor groove adaptability, which easily leads to loose bonding and unstable molding quality due to asynchronous pressing and size mismatch.

[0005] This utility model provides the following technical solution: an integrated bonding and pressing molding device for water-blocking layer and insulation layer of insulated cable, including a base plate, a limit tube fixedly connected to the upper surface of the base plate, a tapered guide tube fixedly connected to the upper surface of the base plate, a discharge pipe fixedly connected to the tail end of the tapered guide tube, and an electric heating wire fixedly wound on the outer surface of the discharge pipe; A set of fixing plates is fixedly connected to the upper surface of the base plate, and two pressing rollers are rotatably connected between the set of fixing plates. The surfaces of the two pressing rollers are provided with pressing grooves. The surface of the limiting tube is rotatably fitted with a rotating disk, and a connecting rod is fixedly connected to the surface of the rotating disk. One end of the connecting rod is fixedly connected to a strap frame.

[0006] Preferred technical solution 1: A first motor is fixedly connected to the surface of one of the fixed plates, the output end of the first motor passes through the connected fixed plate and is fixedly connected to the corresponding pressing roller, one end of each of the two pressing rollers extends to the outside of the connected fixed plate and is fixedly connected to a first gear, and the two first gears mesh with each other.

[0007] Preferred technical solution 2: A second motor is fixedly connected to the upper surface of the limiting tube, a second gear is fixedly connected to the output end of the second motor, a gear ring is fixedly connected to the back of the rotating disk, and the second gear meshes with the gear ring.

[0008] Preferred technical solution 3: A protective tube is provided on the outside of the electric heating wire, and the protective tube is fixedly connected to the tapered guide tube.

[0009] Preferred technical solution four: A set of limiting rollers is rotatably installed between the two inner side walls of the threading frame.

[0010] Preferred technical solution five: The inner diameter of the limiting tube matches the size of the cable and the insulation layer, the size of the pressing groove matches the size of the cable, the insulation layer and the water-blocking layer, and a gap is left between the inner diameter of the discharge tube and the cable, the insulation layer and the water-blocking layer.

[0011] Compared with the prior art, this utility model provides an integrated bonding and pressing molding device for the water-blocking layer and the insulation layer of an insulated cable, which has the following beneficial effects: In use, one end of the cable with the insulation layer is first passed through the limiting tube for initial positioning. Then, the water-blocking tape is passed through the tape-passing frame. The second motor is then started to drive the second gear to rotate, thereby driving the gear ring and the rotating disk to rotate. The rotating disk drives the tape-passing frame to rotate synchronously around the cable through the connecting rod, so that the water-blocking tape is evenly wrapped around the surface of the cable insulation layer. The cable with the water-blocking tape wrapped around it continues to be conveyed forward, passing through the tapered guide tube and the discharge pipe at the tail end in sequence. At this time, the cable, insulation layer and water-blocking tape in the discharge pipe are preheated by electric heating wire to promote the initial bonding of the water-blocking tape and the insulation layer. The process begins with bonding. The heated cable then enters between two pressing rollers. The first motor drives the corresponding pressing roller to rotate. This pressing roller meshes with a first gear on one end of the other pressing roller, causing the two rollers to rotate synchronously in opposite directions. Using the pressing grooves on the surfaces of the two rollers, the cable is integrally pressed together, ultimately achieving a tight bond between the water-blocking layer and the insulation layer. This device precisely positions the cable using a limiting tube, and, in conjunction with a rotating disc driven by a second motor and a tape-threading frame, ensures that the water-blocking tape is evenly wrapped around the insulation layer, avoiding the uneven wrapping problems of traditional methods. Simultaneously, the pre-treatment with electric heating wire promotes initial bonding between the water-blocking tape and the insulation layer, and the pressing rollers achieve tight bonding, thus improving overall molding efficiency and quality.

Then, the water-blocking tape is passed through the tape-passing frame 11. Next, the second motor 14 is started to drive the second gear 15 to rotate, thereby driving the gear ring 16 and the rotating disk 9 to rotate. The rotating disk 9 drives the tape-passing frame 11 to rotate synchronously around the cable through the connecting rod 10, so that the water-blocking tape is evenly wrapped around the surface of the cable insulation layer. The cable with the water-blocking tape wrapped around it continues to be conveyed forward, passing through the tapered guide tube 3 and the discharge tube 4 at the tail end in sequence. At this time, the cable, insulation layer and water-blocking tape in the discharge tube 4 are preheated by the electric heating wire 5 to promote the initial bonding of the water-blocking tape and the insulation layer.

At the same time, the pretreatment of the electric heating wire 5 can promote the initial bonding of the water-blocking tape and the insulation layer, and achieve tight pressing through the pressing rollers 7, thereby improving the overall molding efficiency and quality.
