Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a printing device for low-voltage cable processing. Background Technology

[0002] Cables are conductors covered with insulation, protective layers, and shielding layers used to transmit power or signal current and signal voltage. According to voltage, they can be divided into high-voltage cables and low-voltage cables. Although low-voltage cable lines are more expensive and more difficult to lay and maintain compared with low-voltage overhead lines and low-voltage overhead insulated lines, they are widely used in low-voltage power distribution systems because of their reliable operation, no need for poles, no land occupation, no obstruction of appearance, and less susceptibility to external influences.

[0003] Inkjet printing equipment can print information such as specifications, production batch, date, and traceability codes on the surface of cables. In complex power grids or communication networks, maintenance personnel can quickly obtain basic cable information and trace the source and parameters of production through inkjet printing. Some inkjet printing equipment uses solvent-based inks and water-based inks to print on cables. When the cable is transported after printing, the ink on the cable surface is in an uncured state. When the cable moves on the conveyor belt or rollers, there may be mutual friction or squeezing, which may cause the undried ink to be scraped off, making the printed content unreadable and requiring reprinting, thus affecting the efficiency of cable printing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-6 As shown, a low-voltage cable processing inkjet printing device includes a fixed frame 1 and a conveying mechanism 2 disposed on the top of the fixed frame 1. The top of the fixed frame 1 is provided with an inkjet printer body 3, wherein the bottom of the inkjet printer body 3 is fixedly connected to a printhead conduit, and an inkjet printhead is fixedly connected to the outside of the printhead conduit. It is the same as the inkjet printer, printhead conduit and inkjet printhead in the inkjet printing device for low-voltage cable processing provided in CN219486948U. It is prior art. The specific structure, working principle and possible control and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not be further elaborated in detail. The top of the fixed frame 1 is provided with a PLC controller 4. The PLC controller 4 is connected to the first fan 10, the second fan 19, the temperature sensor 20, the heating tube 18, the circulating pump 25 and the heating plate 11 through wires. Under the action of the PLC controller 4, the normal operation of the first fan 10 and the heating plate 11 can be controlled. The drying assembly 5, under its function, dries the ink printed on the cable surface, preventing ink overflow or scratches. It is located outside the conveying mechanism 2. The drying assembly 5 includes a drying rack 51 fixedly connected to the top of the mounting frame 1. The drying rack 51 positions the hot air duct 52, allowing the low-voltage cable, after printing, to enter the hot air duct 52. The drying rack 51 contains the hot air duct 52, through which hot air is sprayed to dry the outside of the low-voltage cable. A connecting pipe 53 connects to the top of the hot air duct 52. A flexible hose 54 is located outside the drying rack 51. The flexible hose 54 and connecting pipe 53 allow hot air from inside the hot air box 55 to be transported to the hot air duct. Inside the drying rack 51, a hot air box 55 is fixedly connected to the top. The hot air box 55 heats the air entering the hot air box 55. A preheating rack 56 is fixedly connected to the top of the fixed frame 1. A preheating pipe 57 is fixedly connected to one side of the inner wall of the preheating rack 56. Before entering the hot air pipe 52, the printed cable first enters the preheating pipe 57. The preheating pipe 57 has a shrinkage structure. Under the action of the preheating pipe 57, the ink on the surface of the cable can be preheated to a temperature of 40-60℃, thereby preventing ink bubbling. A cooling rack 58 is fixedly connected to the top of the fixed frame 1. A first cooling pipe 59 is fixedly connected to the top of the inner cavity of the cooling rack 58. After the drying operation is completed in the cable printing area, the cable enters the cooling pipe, so that the dried ink can be cooled down quickly and the ink can be completely cured.

[0019] The hot air duct 52 has multiple nozzles 6 inside, allowing hot air to be ejected from the duct 52 to thoroughly dry the printed area of ​​the low-voltage cable. Connecting brackets 7 are fixedly connected to both sides of the inner wall of the drying rack 51. These connecting brackets 7 stabilize the hot air duct 52, allowing the low-voltage cable to enter and dry. One side of the connecting bracket 7 is fixedly connected to the outside of the hot air duct 52. A top pipe 8 connects to the outside of the connecting pipe 53, and a connector 9 connects to the top of the top pipe 8. When the worker needs to disassemble or repair the flexible hose 54, they rotate the connector 9, disengaging it from the top pipe 8. Simultaneously, the top of the connector 9 connects to the flexible hose 54. The end of pipe 54 furthest from the first fan 10 is rotatably connected, while connector 9 is in communication with hose 54. The outer side of connector 9 is threaded to the inner wall of top pipe 8. The end of connector 9 furthest from top pipe 8 is connected to the end of hose 54. The end of hose 54 furthest from connector 9 is connected to the first fan 10. Under the action of the first fan 10, the pressure inside hot air box 55 can be adjusted, allowing outside air to enter the interior of hot air box 55. At the same time, it can extract and transport air with a certain temperature inside hot air box 55. The bottom of the first fan 10 is fixedly connected to the top of hot air box 55. Heating plates 11 are fixedly connected to both sides of the inner wall of hot air box 55. Under the action of multiple heating plates 11, the air inside hot air box 55 can be heated. The air inside the hot air box 55 is heated, increasing its heat content. A resistance wire is installed inside the heating plate 11, which heats the air inside the hot air box 55. These are all existing technologies. The specific structure, working principle, and possible control and spatial arrangement of these technical features can be achieved using conventional methods in this field. This technical solution will not be further elaborated upon. A second temperature sensor is installed at the heating plate 11, and the second temperature sensor is connected to the PLC controller 4 via a wire. When the temperature reaches the threshold of the second temperature sensor, the PLC controller 4 cuts off the current, thereby stopping the heating plate 11 from working. The air inlet of the first fan 10 is connected to the hot air box 55, and the preheating pipe 57... The top of the preheating chamber 17 is connected to an air inlet pipe 16, and the top of the air inlet pipe 16 is connected to a preheating box 17. A heating pipe 18 is fixedly connected to one side of the inner wall of the preheating box 17. A second fan 19 is fixedly connected to the top of the preheating rack 56, and the air outlet of the second fan 19 is connected to the preheating box 17. A temperature sensor 20 is fixedly connected to the bottom of the inner cavity of the preheating box 17. The heating pipe 18 is composed of a resistance wire, insulating filler, and a metal sheath, all of which are existing technologies. The specific structure, working principle, and possible control and spatial arrangement of these technical features can be achieved using conventional choices in the field. This technical solution will not be further elaborated in detail. Under the action of the heating pipe 18, the air inside the preheating box 17 can be heated. At the same time, under the action of the temperature sensor 20...To prevent the air temperature inside the preheating box 17 from becoming too high and affecting the preheating of the cables, the second fan 19 is activated when the temperature reaches a specified threshold. The second fan 19 then sprays hot air through the preheating pipe 57, which has multiple holes to preheat the cables and prevent ink bubbling on the cable's outer surface. A first heat insulation plate 21 is fixedly connected to one side of the inner wall of the preheating rack 56, and a second heat insulation plate 22 is fixedly connected to one side of the inner wall of the cooling rack 58. These two heat insulation plates effectively block heat from flowing freely and affecting normal operation in each area. A circulation box 23 is fixedly connected to the top of the cooling rack 58, allowing the coolant to continuously circulate throughout the entire passageway. A heat dissipation plate 24 is fixedly connected to the top of the circulation box 23 to absorb heat from the coolant. After entering the circulation tank 23, the coolant can dissipate heat through the heat sink 24. A circulation pump 25 is fixedly connected to the top of the circulation tank 23. Under the action of the circulation pump 25, the coolant inside the circulation tank 23 can continuously flow. The inlet of the circulation pump 25 is connected to the circulation tank 23, and the outlet of the circulation pump 25 is connected to a delivery pipe 26. A side pipe 27 is connected to the outside of the first cooling pipe 59. The coolant delivered through the delivery pipe 26 can enter the interior of the first cooling pipe 59, and then enter the interior of the second cooling pipe 28 through the side pipe 27. The end of the side pipe 27 away from the first cooling pipe 59 is connected to the second cooling pipe 28. A circulation pipe 29 is connected to the outside of the second cooling pipe 28. The top of the circulation pipe 29 is connected to the bottom of the circulation tank 23. The coolant flowing inside the first cooling pipe 59 and the second cooling pipe 28 can enter the interior of the circulation tank 23 through the circulation pipe 29.

[0020] The front and rear surfaces of the fixed frame 1 are fixedly connected to the transmission frame 12. Under the action of the transmission frame 12, the guide roller 13 can be placed stably. The top of the transmission frame 12 is fixedly connected to the guide roller 13. The number of guide rollers 13 is set to eight, so that two low-voltage cables can be conveyed at the same time. The top of the guide roller 13 is rotatably connected to the guide ring 14. Under the action of the two guide rings 14, the low-voltage cable can be clamped and conveyed without damaging the outer layer of the low-voltage cable. The top of the fixed frame 1 is fixedly connected to the fixed bracket 15. Under the action of the fixed bracket 15, the inkjet printer body 3 can be placed and positioned, so that the inkjet printer body 3 can be used to perform inkjet printing operations on the low-voltage cable.

[0021] Working Principle: When the operator uses this device to print on low-voltage cables, the low-voltage cable first enters between the two conductor rings 14. Simultaneously, under the action of the conveying mechanism 2, the low-voltage cable is conveyed until it reaches the preheating pipe 57. The second fan 19 is then activated, and the heating pipe 18 begins operation. After the temperature inside the preheating chamber 17 reaches the specified threshold, the second fan 19 causes hot air to flow through the holes inside the preheating pipe 57, thus preheating the ink and preventing foaming. Then, under the action of the conveying mechanism 2, the low-voltage cable moves to the drying rack 51. Under the action of the printer body 3 and the print head, the low-voltage cable is printed. After printing, the low-voltage cable continues to be conveyed until the printing position enters the hot air pipe 52. Simultaneously, the operator... The PLC controller 4 activates the heating plate 11, which heats the air inside the hot air box 55. The heated air, under the action of the first fan 10, is then transported through the hose 54 and connecting pipe 53 to the hot air pipe 52. The hot air is then ejected through multiple nozzles 6, drying the printing area of ​​the low-voltage cable. After drying, the cable, under the action of the conveying mechanism 2, enters the cooling pipe. The circulation pump 25 is then activated, causing the coolant to continuously flow through the conveying pipe 26, side pipe 27, first cooling pipe 59, second cooling pipe 28, and circulation pipe 29. This cools the ink at the printing area of ​​the cable, allowing it to solidify quickly and preventing ink overflow or scratches, thus improving the printing efficiency of the low-voltage cable to some extent.
