Description

Technical Field

[0001] The present invention relates to the technical field of cable production, in particular to a cable production spraying device. Background Art

[0002] Spraying is required during cable production, and extrusion spraying is the core coating process for cables. The process involves melting and plasticizing thermoplastic materials (such as PVC, PE, and hot-melt adhesives) through an extrusion device, then continuously and evenly coating them on the surface of bare wires or substrates through a circular die, forming insulation, sheathing, moisture barriers, or functional coatings (such as flame-retardant and wear-resistant coatings). This process combines the continuity of extrusion with the precision of spraying, making it a core technology for industrialized cable production and particularly suitable for cables with diameters of 0.5 to 50 mm (power cables, communication cables, automotive wiring harnesses, etc.).

[0003] Publication No. CN222440257U discloses a cable production spraying device. However, when using the existing cable production spraying device, it is not convenient to clean and preheat the bare wire before extrusion spraying. The cable after extrusion spraying directly enters the cooling water tank for cooling, which easily causes heat waste and is not energy-saving and environmentally friendly. For materials that are difficult to adhere (such as fluoroplastics), a layer of primer (such as modified resin) needs to be applied first to enhance the bonding strength of subsequent coatings. During operation, it is not convenient and quick, thereby affecting the efficiency and quality of spraying, and further affecting the efficiency and quality of cable production.

When the rotating rod 701 rotates, it can drive the rubber wheel 702 to rotate, and then drive the rotating ring 601 to rotate.

[0039] See also Figure 8 The power mechanism includes a driven bevel gear 801 fixedly sleeved on the side wall of the rotating rod 701, and the inner wall of the connecting pipe 20 is fixedly connected to a mounting plate 802, and the side wall of the mounting plate 802 is rotatably connected to a rotating fan 804 through a third rotating shaft 803. The side wall of the third rotating shaft 803 is fixedly sleeved with a driving bevel gear 805, and the driving bevel gear 805 is meshed with the driven bevel gear 801. When air flows in the connecting pipe 20, it can impact the surface of the rotating fan 804 to cause it to rotate. When the rotating fan 804 rotates, the driving bevel gear 805 can be driven to rotate through the third rotating shaft 803, thereby driving the rotating rod 701 to rotate through the driven bevel gear 801.

[0040] Working principle: When in use, first select a suitable ring 12 according to the diameter of the bare wire, then start the motor 201, the rotation of the motor 201 drives the rotation of the first rotating shaft 202, thereby driving the ring 12 to rotate through the connecting rod 203, when the connecting tube 13 and the side wall of the tapered tube 21 are against each other, it can push the tapered tube 21 to move upward, and at the same time, the first spring 302 is compressed, thereby rotating the required ring 12 to a vertically upward state. At this time, the tapered tube 21 can move downward under the action of the first spring 302 and be inserted into the connecting tube 13 and against the inner wall, thereby realizing the automatic connection between the connecting tube 13 and the tapered tube 21.

[0041] Next, the bare wire is transported by the conveying module 103, passes through the ring 12 and enters the spraying module 101 through the feed port 105 for extrusion spraying. At the same time, the fan 15 is started to perform exhaust operation, and the cable after spraying enters the waste heat recovery cover 17 through the through hole 18. Moreover, when exhausting, the external air enters the waste heat recovery cover 17 through the air inlet pipe 19, so that the waste heat on the surface of the cable after spraying can be recovered. The hot air can be blown onto the surface of the cable before spraying through the connecting pipe 20, the first telescopic tube 22, the tapered tube 21 and the connecting pipe 13, so that the waste heat of the cable after spraying can be used to preheat the cable before spraying, and the impurities on the surface of the cable can be blown clean, which is not only more energy-saving and environmentally friendly, but also ensures the quality of cable production.

[0042] When air flows through the connecting pipe 20, it can impact the surface of the rotating plate 1003, causing the rotating plate 1003 to rotate clockwise along the second rotating shaft 1002. At the same time, it can drive the gear 1004 to rotate and push the rack 1007 to move downward along the guide rod 1006. At the same time, the third spring 1008 is compressed, and when the rack 1007 moves downward, it can drive the moving rod 1009 to move downward synchronously, thereby causing the connecting rod 1010 to rotate and push the moving block 906 to move toward the second support plate 903. When the moving block 906 moves, it drives the L-shaped plate 909 and the push plate 907 to move synchronously, so that the push pin 902 moves from the top of the L-shaped plate 909 to the top of the push plate 907.

[0043] At this time, the gravity plate 406 can move downward along the storage box 404 under the action of gravity, so that the primer raw material stored in the storage box 404 can be squeezed and dripped onto the surface of the cable after passing through the fixed tube 402, the second telescopic tube 405 and the movable tube 403. Moreover, when the ring 12 is selected, when the ring 12 is against the side wall of the pushing block 503, the movable tube 403 can be pushed to move upward. At the same time, the second spring 502 is compressed, and the pushing block 503 can be moved to the top of the ring 12, so that when the cable diameter changes, the primer raw material can be ensured to be at the same height from the bare wire when dripping, and the squeezing action of the gravity plate 406 can ensure the dripping speed, thereby ensuring the dripping effect.

[0044] Moreover, when air flows in the connecting tube 20, it can impact the surface of the rotating fan 804 to cause it to rotate. When the rotating fan 804 rotates, it can drive the active bevel gear 805 to rotate through the third rotating shaft 803, thereby driving the rotating rod 701 to rotate through the driven bevel gear 801. When the rotating rod 701 rotates, it can drive the rubber wheel 702 to rotate, and then drive the rotating ring 601 to rotate. At this time, the primer material dripped on the cable surface can be evenly applied with the brush 602, which is more convenient and quick, and ensures the effect of primer application, the effect of subsequent spraying, and thus the production quality of the cable.

[0045] When spraying is stopped, the fan 15 is stopped. At this time, the exhaust operation is no longer performed, and the rack 1007 can move upward and reset under the action of the third spring 1008, and can drive the gear 1004 and the second rotating shaft 1002 to rotate counterclockwise, thereby driving the rotating plate 1003 to rotate upward and reset. Moreover, when the rack 1007 moves upward, it drives the moving rod 1009 to move upward synchronously, causing the connecting rod 1010 to rotate. At the same time, it pulls the moving block 906, the L-shaped plate 909 and the pushing plate 907 to move away from the second support plate 903, so that the pushing pin 902 can slide along the inclined surface 908 to the top of the L-shaped plate 909, thereby pushing the gravity plate 406 to move upward and reset. Moreover, under the action of the one-way valve, the supply of primer raw materials is stopped, which is more convenient and quick.
