Description

Technical Field

[0001] This invention relates to the field of cable production and processing, specifically to a fluoropolymer-insulated marine wire harness cable and its manufacturing equipment. Background Technology

[0002] When cables are used on ships, they must have good waterproof performance. Secondly, during the mass production of the cable, multiple cable reels are required to wind it up in sequence. However, the traditional winding process is quite complicated and requires a lot of manpower.

[0003] Chinese utility model patent application number 202120810588.2 discloses a mineral cable winding device. Through the arrangement of a leveling component and a cable laying component, it achieves the purpose of stretching and leveling the cable before evenly arranging it on the winding reel during winding, effectively avoiding bending and stacking of the wound cable. While this technology achieves cable winding, it is only suitable for single winding and has relatively poor practicality. Summary of the Invention

[0004] In order to meet the above-mentioned dual requirements for cable performance and cable winding, this invention proposes a fluoropolymer insulated marine cable harness and its manufacturing equipment.

[0005] The technical problem to be solved by this invention is achieved by the following technical solution: A fluoropolymer-insulated marine cable harness is provided, comprising an outer sheath, an outer insulation layer inside the outer sheath, an abrasion-resistant layer inside the outer insulation layer, and a waterproof filler layer inside the abrasion-resistant layer; two wire cores are disposed inside the waterproof filler layer. This cable possesses excellent abrasion resistance, waterproof performance, and superior insulation properties.

[0006] Furthermore, each conductor consists of an inner insulation layer and an inner core encased within the inner insulation layer. The inner insulation layer further enhances the insulation performance.

[0007] This invention also proposes a manufacturing apparatus for fluoropolymer-insulated marine cable harnesses. The apparatus comprises a main frame and a reel supply device, a winding device, and a loading assembly mounted on the main frame. The winding device includes a mounting shaft and an assembly plate connecting the mounting shaft. A reinforcement device is mounted on the assembly plate. The reel supply device includes an L-shaped loading cylinder located to the left of the mounting shaft. The loading assembly includes an auxiliary moving frame adapted to the winding device. The reel supply device provides cable reels, and the winding device assists in winding the fluoropolymer-insulated marine cable harness. The loading assembly unloads the wound cable reels. The mounting shaft mounts the cable reels. The reinforcement device secures the cable reels mounted on the mounting shaft. The L-shaped loading cylinder can hold unused cable reels. The auxiliary moving frame is horizontally movable.

[0008] Furthermore, the L-shaped loading cylinder is placed on the main frame; the L-shaped loading cylinder has interconnected transverse and longitudinal slots; the transverse slot connects to the right end of the L-shaped loading cylinder; the longitudinal slot connects to the upper end of the L-shaped loading cylinder. Under normal conditions, unused cable reels are stacked in the longitudinal slot. The height of the transverse slot is set to match the diameter of a single cable reel.

[0009] Furthermore, the reel supply device also includes a hydraulic cylinder mounted on an L-shaped loading drum and a transverse push block connected to the hydraulic cylinder; the transverse push block is slidably mounted in a transverse groove. By pushing the transverse push block with the hydraulic cylinder, the lowermost cable reel can be pushed to the right out of the loading drum and positioned on the mounting shaft.

[0010] Furthermore, the winding device also includes a side base, a No. 1 motor mounted on the side base, and two rear auxiliary rods mounted on the side base; the No. 1 motor is connected to an assembly plate. The assembly plate can position the cable reel after it has been loaded. The shaft of the No. 1 motor is concentrically arranged with the mounting shaft. The No. 1 motor drives the mounting shaft to rotate, which performs the cable winding operation.

[0011] Furthermore, an eccentric auxiliary rod is welded to the assembly plate, and an annular groove is provided on the side base for slidingly mounting the eccentric auxiliary rod. This structure increases the structural reliability of the assembly plate during rotation.

[0012] Furthermore, the reinforcement device consists of an offset rod mounted on the assembly plate via bearings, a pressure plate hinged to the upper end of the offset rod, a spring connected to one side of the pressure plate, and a sliding seat connected to the spring. When an unused cable reel is pushed to abut the assembly plate, the offset rod and the pressure plate can be manually rotated so that the end of the pressure plate away from the spring presses and secures the cable reel under elastic force.

[0013] Furthermore, the assembly plate is provided with a circular arc groove No. I for sliding the sliding seat. This structure is a conventional design for sliding structures.

[0014] Furthermore, the loading assembly also includes a No. II motor mounted on the upper part of the main frame, a guide rail mounted on the upper part of the main frame, a lead screw connected to the No. II motor, and a discharge roller frame mounted on the lower part of the main frame; the auxiliary moving frame is connected to the lead screw and is slidably mounted on the guide rail. That is, the auxiliary moving frame can move horizontally under the transmission action of the lead screw and nut.

[0015] Furthermore, the auxiliary moving frame has a vertical slot, and the rear end of the main frame has a No. II arc slot. Of the two rear auxiliary rods, the lower one is mounted on the main frame via a bearing, while the other slides and is hinged to both the vertical slot and the No. II arc slot. The central angle corresponding to the No. II arc slot is not less than 90 degrees, and the center position of the No. II arc slot corresponds to the position of the lower rear auxiliary rod. That is, the horizontal movement of the auxiliary moving frame allows the upper rear auxiliary rod to rotate with the lower rear auxiliary rod as the center, thereby flipping the control-side base and rotating the central axis of the mounting shaft from a horizontal state to a vertical state, facilitating the unloading of the wound cable reel.

[0016] The beneficial effects of this invention are: This invention provides a cable with good waterproof and insulation properties, which can sequentially realize four steps: loading the reel, fixing the reel, winding the cable, and unloading the reel. This makes it convenient to wind up a large number of cables one by one, and the winding operation is relatively convenient and requires less manpower. Attached Figure Description

Two wire cores are located inside the waterproof filler layer 23. This cable possesses excellent abrasion resistance, waterproof performance, and superior insulation properties.

[0022] Each conductor consists of an inner insulation layer 24 and an inner core 25 enclosed within the inner insulation layer 24. The inner insulation layer 24 further enhances the insulation performance.

[0023] like Figure 2 and Figure 6 As shown, a manufacturing apparatus for fluoropolymer-insulated marine cable harnesses comprises a main frame 1 and a reel supply device, a winding device, and a loading assembly mounted on the main frame 1. The winding device includes a mounting shaft 10 and an assembly plate 2 connecting the mounting shaft 10. A reinforcing device is mounted on the assembly plate 2. The reel supply device includes an L-shaped loading cylinder 3 located to the left of the mounting shaft 10. The loading assembly includes an auxiliary moving frame 4 adapted to the winding device.

The mounting shaft 10 mounts the cable reels. The reinforcing device secures the cable reels mounted on the mounting shaft 10. The L-shaped loading cylinder 3 can hold unused cable reels. The auxiliary moving frame 4 is horizontally movable.

[0024] like Figure 3 and Figure 4 As shown, the L-shaped loading cylinder 3 is placed on the main frame 1; the L-shaped loading cylinder 3 has interconnected transverse grooves 3a and longitudinal grooves 3b; the transverse groove 3a connects to the right end of the L-shaped loading cylinder 3; the longitudinal groove 3b connects to the upper end of the L-shaped loading cylinder 3. Under normal conditions, unused cable reels are stacked in the longitudinal groove 3b. The height of the transverse groove 3a is set to be consistent with the diameter of a single cable reel.

[0025] like Figure 4 As shown, the reel supply device also includes a hydraulic cylinder 5 mounted on the L-shaped loading cylinder 3 and a transverse push block 6 connected to the hydraulic cylinder 5; the transverse push block 6 is slidably mounted in the transverse groove 3a. By pushing the transverse push block 6 with the hydraulic cylinder 5, the lowermost cable reel can be pushed to the right out of the loading cylinder 3 and positioned on the mounting shaft 10.

[0026] like Figure 1 and Figure 6 As shown, the winding device also includes a side base 7, a No. 1 motor 8 mounted on the side base 7, and two rear auxiliary rods 9 mounted on the side base 7; the No. 1 motor 8 is connected to the assembly plate 2. The assembly plate 2 can position the cable reel after loading. The shaft of the No. 1 motor 8 is concentrically arranged with the mounting shaft 10. The No. 1 motor 8 drives the mounting shaft 10 to rotate, which can perform the cable winding operation.

[0027] like Figure 6 As shown, an eccentric auxiliary rod 11 is welded to the assembly plate 2, and an annular groove 7a is provided on the side base 7 for slidingly mounting the eccentric auxiliary rod 11. The above structure can increase the structural reliability of the assembly plate 2 when it rotates.

[0028] like Figure 6 and Figure 7 As shown, the reinforcement device consists of an offset rod 12 mounted on the assembly plate 2 via bearings, a pressure plate 13 hinged to the upper end of the offset rod 12, a spring 14 connected to one side of the pressure plate 13, and a sliding seat 15 connected to the spring 14. When an unused cable reel is pushed to abut against the assembly plate 2, the offset rod 12 and the pressure plate 13 can be manually rotated so that the end of the pressure plate 13 away from the spring 14 is pressed and fixed to the cable reel under the elastic force.

[0029] like Figure 7 As shown, the assembly plate 2 is provided with a circular arc groove 2a (I) for sliding the sliding seat 15. This structure is a conventional design for a sliding structure.

The central angle corresponding to the No. II arc slot 1a is not less than 90 degrees, and the position of the center of the No. II arc slot 1a corresponds to the position of the lower rear auxiliary rod 9. That is, the horizontal movement of the auxiliary moving frame 4 allows the upper rear auxiliary rod 9 to rotate with the lower rear auxiliary rod 9 as the center, thereby flipping the control-side base 7 and rotating the central axis of the mounting shaft 10 from a horizontal state to a vertical state, so as to facilitate the unloading of the wound cable reel.

[0032] Before using this invention, simply stack the cable reels in the longitudinal groove 3b.

[0033] The specific usage steps are as follows: Step 1 - Reel Loading: Hydraulic cylinder 5 pushes the horizontal push block 6 to the right, so that the bottommost cable reel is pushed onto the mounting shaft 10 and abuts against the assembly plate 2.

[0034] Step 2 - Fixing the reel: Manually rotate the offset rod 12 and the pressure plate 13 so that the end of the pressure plate 13 away from the spring 14 presses and fixes the cable reel.

[0035] Step 3 - Cable winding: Manually fix one end of the cable to the cable reel, and then drive the fixed cable reel to rotate using motor 8 to complete the winding.

[0036] Step 4 - Unloading the reel: Motor II 16 drives the lead screw 17 to rotate, causing the cable reel that has been wound up to rotate 90 degrees. Then, the cable reel is released from its fixed state, allowing it to fall onto the unloading roller frame 19, thus completing the unloading.
