The copper strands pass through the guide plate of the production line and pass through the polyethylene sheath extrusion machine, buffer layer winding machine, steel wire armoring machine, outer layer winding machine and protective layer wrapping machine; (3) Wrap two layers of 0.3mm thick semi-conductive water-resistant cushion layers on the outside of the insulation layer of the copper stranded wire as a longitudinal water-resistant layer; extrude a lead sheath on the wrapped semi-conductive water-resistant cushion layer as a radial water-resistant layer; extrude a polyethylene sheath on the lead sheath as a non-metallic sheath layer of the insulated core; cable the three insulated cores into one and tie them with two layers of 0.2mm thick rubberized cloth tape; wrap a 1.0mm thick polypropylene fiber buffer layer on the outside of the polyethylene sheath and coat it with asphalt; armor the buffer layer with steel wire and coat it with asphalt; wrap two layers of 1.0mm thick polypropylene fiber outer sheath on the outside of the steel wire armor and coat it with asphalt; wrap a protective layer on the outer sheath; and finally send the submarine cable out through a traction machine; (4) When market demand fluctuates, cross-scheduling can quickly adjust the production plan, drive components to reduce the conveying speed of copper strands and the production speed of the production line, ensure that the production line can flexibly respond to market changes, and reduce inventory backlogs and out-of-stock risks; (5) When a production line or equipment fails, the task is allocated to other production lines through the cooperation of the drive components and guide components to ensure that the overall production is not affected.

[0015] Beneficial effects of the present invention: When it is necessary to reduce the conveying and production speed, the present invention drives the connecting plate to move, the telescopic plate drives the belt on one side of the first transmission belt to move, and the two pulleys drive the shaft to rotate, rotating the rotating plate ninety degrees, thereby replacing the positions of the first gear and the second gear. At this time, the second gear with a small radius drives the first gear with a large radius to rotate, thereby reducing the conveying speed of the copper stranded wire, slowing down the production speed of the production line, and avoiding accumulation in the warehouse.

[0016] The present invention connects the sliding frame at the output end of the driving motor with the arc block of the first gear, and the arc block of the second gear is connected to the sliding frame at the bottom of the second transmission belt pulley. The first gear rotates and engages with the second gear, the second transmission belt is driven, the conveying wheel rotates at high speed, and through the engagement of the first bevel gear and the second bevel gear, the four groups of conveying wheels rotate synchronously at high speed to convey the copper stranded wire.

[0017] When the electromagnetic suction rod of the present invention is not connected to the threading plate, the rotation of the guide ring driven by the telescopic plate only rotates around the surface of the copper stranded wire, which will not affect the conveying position of the copper stranded wire, and the driving component changes the conveying direction.

[0018] The present invention connects the guide ring and the threading plate through an electromagnetic suction rod, and then when the telescopic plate drives the guide ring to rotate, the threading plate will also synchronously rotate along the surface of the central column with the rotating ring, and the conveying direction of the copper stranded wire will be changed. Because the four groups of threading plates and guide rings are staggered up and down, there will be no interference after rotation. The copper stranded wire that needs to be suspended due to a fault in a certain production line is rotated to the next group of production lines to wait. After the copper stranded wire in the next group of production lines is conveyed, the prepared copper stranded wire of this group is sent into the production line to complete the production of the submarine cable.

[0019] Compared with the existing technology, the present invention uses a steering assembly to transport copper stranded wires to different production lines to prepare submarine cables. The driving assembly can adjust the production speed to fast or slow according to market demand. The steering assembly cooperates with the driving assembly to change the conveying direction of the copper stranded wire, thereby making timely adjustments to respond to equipment failures or market demands without significantly affecting production efficiency.

[0025] The submarine cable cross production optimization system based on TOC bottleneck constraint includes a base 1, on which four groups of production lines 2 are arranged at equal intervals. A steering assembly 3 is provided at the top of the center of the base 1. The steering assembly 3 includes a central column 31. The bottom of the central column 31 is fixedly connected to the base 1, and four groups of threading plates 32 are rotatably installed on the surface of the central column 31. The interior of the threading plate 32 passes through the copper stranded wire 34. The production line 2 includes a control console 21, which is fixed on the base 1 and faces the control console 21.

A drive motor 46 is fixed on one side of the mounting frame 43, and the output end of the drive motor 46 is alternately engaged with the first gear 47 and the second gear 48. When the device is used, the insulated copper strands 34 are divided into four groups and sent to the four groups of production lines 2 through the steering assembly 3 for wrapping and extrusion to prepare submarine cables. The conveying speed of the copper strands 34 is adjusted by the cooperation of the drive assembly 4 and the traction machine at the outer end. When market demand fluctuates, cross-scheduling can quickly adjust the production plan. The drive assembly 4 reduces the conveying speed of the copper strands 34 and the production speed of the production line 2, ensuring that the production line 2 can flexibly respond to market changes and reduce inventory backlogs and out-of-stock risks. When a production line 2 or equipment fails, the task is allocated to other production lines 2 through the cooperation of the drive assembly 4 and the steering assembly 3 to ensure that the overall production is not affected.

[0026] In this embodiment, the production line 2 also includes a polyethylene sheath extrusion machine 23. The console 21 is located on one side of the guide plate 22 and is fixed with the polyethylene sheath extrusion machine 23.

A lead sheath is extruded outside the wrapped semiconductor resistive water cushion layer, a polyethylene sheath is extruded outside the lead sheath, and cable wrapping is performed. A buffer layer is wound around the polyethylene sheath and coated with asphalt. Steel wire armor is performed outside the buffer layer and coated with asphalt. An outer sheath is wound around the steel wire armor and coated with asphalt. A protective layer is wrapped around the outer sheath. Finally, the submarine cable is sent out by a traction machine. The above-mentioned machines and equipment are all existing technologies for producing submarine cables.

[0027] In this embodiment, the driving assembly 4 also includes a first bevel gear 411, and the first bevel gear 411 is fixed at the axis of the conveying wheels 41 on both sides of the through hole of the guide plate 22. The second bevel gear 412 is fixed at the axis of the conveying wheels 41 at the top and bottom of the through hole of the guide plate 22, and the first bevel gear 411 is meshed with the second bevel gear 412. The top of the conveying wheels 41 on both sides of the guide plate 22 passes through the mounting groove 28 and is installed with a second transmission belt 42, and the other end of the second transmission belt 42 is rotatably installed at the bottom of the mounting frame 43. The bottom of the drive motor 46 and the second transmission belt 42 pulley are both fixed with a slide frame 4 9, an arc block 410 is fixed at the axis of the first gear 47 and the second gear 48, and the arc block 410 is slidably inserted into the two sliding frames 49 respectively. A rotating plate 44 is provided at the bottom of the mounting frame 43, and the first gear 47 and the second gear 48 are both rotatably mounted at the bottom of the rotating plate 44 through bearings. A shaft 45 is fixed at the middle position of the rotating plate 44, and the shaft 45 rotates to pass through the top of the mounting frame 43. The steering assembly 3 also includes a first transmission belt 310, and the first transmission belt 310 is fixedly installed on the top of the two shafts 45. A telescopic plate 39 is fixed on the belt surface of one side of the first transmission belt 310. The storage end of the telescopic plate 39 is rotatably connected to the guide ring 35 through a rotating shaft, and a connecting plate 38 is fixed to the top of the extended end of the telescopic plate 39. An electric push rod 312 is fixed to the surface of the guide plate 22, and the extended end of the electric push rod 312 is fixedly connected to the connecting plate 38. Under normal conditions, the slide frame 49 at the output end of the drive motor 46 is connected to the arc block 410 of the first gear 47, and the arc block 410 of the second gear 48 is connected to the slide frame 49 at the bottom of the second transmission belt 42 pulley. The first gear 47 rotates and engages with the second gear 48. The second transmission belt 42 transmits the power, and the conveying wheel 41 rotates at a high speed, and through the first gear 47, the second gear 48 is engaged with the second gear 48. The second transmission belt 42 transmits the power, and the conveying wheel 41 rotates at a high speed. The first bevel gear 411 is meshed with the second bevel gear 412, and the four sets of conveying wheels 41 rotate synchronously at high speed to convey the copper stranded wire 34. When it is necessary to reduce the conveying and production speed, the electric push rod 312 pushes the connecting plate 38 to move, and the telescopic plate 39 drives the belt on one side of the first transmission belt 310 to move. The two pulleys drive the shaft 45 to rotate, and the rotating plate 44 is rotated ninety degrees, thereby replacing the positions of the first gear 47 and the second gear 48. At this time, the second gear 48 with a small radius drives the first gear 47 with a large radius to rotate, thereby reducing the conveying speed of the copper stranded wire 34, slowing down the production speed of the production line 2, and avoiding accumulation in the warehouse.

[0028] In this embodiment, a guide ring 35 is provided at the bottom of the threading plate 32, and a guide cylinder 36 is provided at the bottom of the guide ring 35. One end of the guide cylinder 36 corresponds to the guide ring 35, and the other end of the guide cylinder 36 corresponds to the through hole of the guide plate 22. The copper stranded wire 34 passes through the guide ring 35 and the guide cylinder 36. A fixing frame 37 is fixed on both sides of the guide cylinder 36, and the fixing frame 37 is fixed on the guide plate 22. The four groups of threading plates 32 and guide rings 35 are all staggered up and down, and the surface of the center column 31 corresponds to the threading plate 32. The rotating ring 33 is installed in the position rotation, and the threading plate 32 is fixed on the outside of the rotating ring 33. The top of the guide ring 35 is fixed with an electromagnetic suction rod 311, and the top of the electromagnetic suction rod 311 is magnetically attracted to the guide ring 35. The steering assembly 3 has two working modes. One is that the electromagnetic suction rod 311 connects the guide ring 35 with the threading plate 32, and then when the telescopic plate 39 drives the guide ring 35 to rotate, the threading plate 32 will also rotate synchronously with the rotating ring 33 along the surface of the center column 31, and the conveying direction of the copper stranded wire 34 is changed. The four sets of threading plates 32 and guide rings 35 are all staggered up and down, so there will be no interference after rotation. The copper stranded wire 34 that needs to be suspended due to a fault in a certain group of production lines 2 is rotated to wait in front of the next group of production lines 2. After the copper stranded wire 34 in the next group of production lines 2 is delivered, the prepared copper stranded wire 34 of this group is sent into the interior of the production line 2 to complete the production of the submarine cable. In simple terms, this process is that after a production line 2 fails, the copper stranded wire 34 is transferred to the next station for waiting, and the next station is waiting. After the production of the copper stranded wire 34 is completed, the waiting copper stranded wire 34 is sent in to continue production. The second working mode of the threading plate 32 and the guide ring 35 is that the electromagnetic suction rod 311 is not connected to the threading plate 32. At this time, the telescopic plate 39 drives the guide ring 35 to rotate only around the surface of the copper stranded wire 34, which will not affect the conveying position of the copper stranded wire 34, and the driving component 4 changes the conveying direction. The electromagnetic suction rod 311 is a common electromagnet structure. After power is turned on, it is adsorbed on the bottom of the threading plate 32 to keep the guide ring 35 and the threading plate 32 connected as a whole.

[0029] When the device is used, the insulated copper strands 34 are divided into four groups and sent to the four production lines 2 through the steering assembly 3 for wrapping and extrusion to prepare submarine cables. The conveying speed of the copper strands 34 is adjusted by the cooperation of the driving assembly 4 and the traction machine at the outer end. When the market demand fluctuates, under normal conditions, the sliding frame 49 at the output end of the driving motor 46 is connected to the arc block 410 of the first gear 47, and the arc block 410 of the second gear 48 is connected to the sliding frame 49 at the bottom of the second transmission belt 42 pulley. The first gear 47 rotates and meshes with the second gear 48. The second transmission belt 42 transmits the power, and the conveying wheel 41 rotates at high speed, and the first bevel gear 411 is connected to the second bevel gear 4 12 is meshed, and the four sets of conveying wheels 41 rotate synchronously at high speed to convey the copper stranded wire 34. When it is necessary to reduce the conveying and production speed, the electric push rod 312 pushes the connecting plate 38 to move, and the telescopic plate 39 drives the belt on one side of the first transmission belt 310 to move. The two pulleys drive the shaft 45 to rotate, and the rotating plate 44 is rotated ninety degrees, thereby replacing the positions of the first gear 47 and the second gear 48. At this time, the second gear 48 with a small radius drives the first gear 47 with a large radius to rotate, thereby reducing the conveying speed of the copper stranded wire 34, slowing down the production speed of the production line 2, and avoiding accumulation in the warehouse. When a certain production line 2 or equipment fails, the steering assembly 3 has two working modes. The operation mode is that the electromagnetic suction rod 311 connects the guide ring 35 with the threading plate 32, and then when the telescopic plate 39 drives the guide ring 35 to rotate, the threading plate 32 will also rotate synchronously with the rotating ring 33 along the surface of the central column 31, and the conveying direction of the copper stranded wire 34 will be changed. Because the four sets of threading plates 32 and guide rings 35 are all staggered up and down, there will be no interference after rotation. The copper stranded wire 34 that needs to be suspended due to a fault in a certain group of production lines 2 is rotated to the next group of production lines 2 to wait. After the copper stranded wire 34 in the next group of production lines 2 is conveyed, the prepared copper stranded wire 34 of this group is sent into the interior of the production line 2 to complete the production of the submarine cable. This process is simple. Simply speaking, when a production line 2 fails, the conveying position of the copper stranded wire 34 is transferred to the next workstation for waiting. After the production of the copper stranded wire 34 at the next workstation is completed, the waiting copper stranded wire 34 is sent in to continue production. The second working mode of the threading plate 32 and the guide ring 35 is that the electromagnetic suction rod 311 is not connected to the threading plate 32. At this time, the telescopic plate 39 drives the guide ring 35 to rotate only around the surface of the copper stranded wire 34, which will not affect the conveying position of the copper stranded wire 34, and the driving component 4 changes the conveying direction. The electromagnetic suction rod 311 is a common electromagnet structure. After power is turned on, it is adsorbed on the bottom of the threading plate 32 to keep the guide ring 35 and the threading plate 32 connected as a whole.
