Description

Technical Field

[0001] The present invention relates to the field of intelligent spraying, and in particular to an intelligent spraying production line for cables. Background Art

[0002] Cable spraying is an important cable processing technology that applies a special coating on the cable surface to enhance the insulation, corrosion resistance, wear resistance and fire resistance of the cable. The main purpose of cable spraying is to protect the cable from environmental factors such as moisture, corrosion, wear and high temperature. Through spraying, a strong and flexible protective layer can be formed, thereby improving the service life and safety of the cable. The materials used for cable spraying usually have excellent insulation, heat resistance and corrosion resistance. Common spraying materials include polymer materials such as polyethylene, polyvinyl chloride, epoxy resin, and special coatings such as fire retardant coatings and corrosion resistant coatings. The selection of these materials depends on the use environment and performance requirements of the cable.

[0003] In the prior art, the cable is often sprayed with a fixed spray head, which results in thicker coating near the spray head and thinner coating far from the spray head, resulting in uneven spraying of the cable. When drying the coating, the high temperature easily damages the coating, resulting in reduced spraying quality. Therefore, we provide an intelligent spraying production line for cables.

The extrusion wheel 46 is rotationally connected to the first rotating cylinder 4, and the rotation axis coincides with its own axis. The extrusion wheel 46 squeezes the elastic airbags 64 in contact.

[0058] The first rotating cylinder 4 drives the first fan blade 43, the containing groove 61, the support tube 41, and the extrusion wheel 46 to rotate. The extrusion wheel 46 rotates to extrude the plurality of elastic airbags 64. The paint squeezed inside by the plurality of elastic airbags 64 is sprayed out in sequence through the plurality of first conveying pipes 66, the plurality of first one-way valves, the plurality of quick connectors 63, the containing groove 61, the support tube 41, the annular pipe 42, and the plurality of nozzles to spray the cable surface.

[0059] At the same time, the support pipe 41 drives the annular pipe 42 and a plurality of spray heads to rotate, thereby performing rotational spraying on the cable surface, thereby achieving uniform spraying on the cable surface.

[0060] When the squeezing wheel 46 passes by, the squeezed elastic airbags 64 rebound, so that the paint in the collecting box 1 passes through the second conveying pipes 65 and the second one-way valves and enters the elastic airbags 64 .

[0061] The plurality of elastic air bags 64 arranged in parallel are staggered so as to make the spraying speed of the spray head more uniform.

[0062] Working process: The staff passes the cable through the first cable opening, the annular pipe 42, the scraper ring 21, the second cable opening, and then connects it to the two transmission mechanisms.

[0063] Afterwards, the staff starts the two conveying mechanisms, the driving motor 3, and a plurality of heating wires 54 through the controller, and the two conveying mechanisms drive the cables to move.

[0064] The driving motor 3 drives the first active bevel gear 31 and the second active bevel gear 33 to rotate, the first active bevel gear 31 drives the first bevel gear ring 44 to rotate, the first bevel gear ring 44 drives the first rotating cylinder 4 to rotate, the first rotating cylinder 4 drives the first fan blade 43, the accommodating groove 61, the support tube 41, and the extrusion wheel 46 to rotate, the extrusion wheel 46 rotates to extrude a plurality of elastic airbags 64, the paint squeezed inside by the plurality of elastic airbags 64 is sprayed out in sequence through a plurality of first conveying pipes 66, a plurality of first one-way valves, a plurality of quick connectors 63, the accommodating groove 61, the support tube 41, the annular pipe 42, and a plurality of nozzles to spray the cable surface.

[0065] At the same time, the support pipe 41 drives the annular pipe 42 and a plurality of spray heads to rotate, thereby performing rotational spraying on the cable surface, thereby achieving uniform spraying on the cable surface.

[0066] The rotation of the first fan blade 43 drives the external air to enter the spraying cylinder 2 through the first rotating cylinder 4 .

[0067] At the same time, the second active bevel gear 33 rotates to drive the second bevel gear ring 52 to rotate, and the second bevel gear ring 52 drives the second rotating cylinder 5 to rotate. The second rotating cylinder 5 drives the second fan blades 53 and several heating wires 54 to rotate, and the second fan blades 53 drive the outside air to enter the spray cylinder 2 through the second rotating cylinder 5. The airflow directions generated by the first fan blades 43 and the second fan blades 53 are opposite, and after colliding at several nozzles, they are ejected through the filter plate 16, the collection pipe 15, several first discharge channels, several filter screens 14, several second discharge channels, several third fan blades 12, and several activated carbon plates 13 in sequence, and then enter the spray cylinder 2 through the first fan blades 43, the second fan blades 53, the first rotating cylinder 4, and the second rotating cylinder 5, forming a cycle to recycle and utilize heat.

[0068] The airflows generated by the first blade 43 and the second blade 53 are in opposite directions and collide at several nozzles, thereby reducing the splashing range of the paint sprayed from the nozzles, preventing the exhaust gas generated by the spraying from leaking out, and driving the excess paint through the filter plate 16 and the collection pipe 15 into the collection box 1 for recovery.

[0069] At the same time, the airflow drives the third blades 12 to rotate, and the third blades 12 drive the stirring shafts 11 and the stirring rods to rotate, so as to evenly stir the paint in the collecting box 1 to prevent the paint from solidifying.

[0070] At the same time, several heating wires 54 combined with temperature sensors heat the airflow to 60-80 degrees Celsius, so that the hot airflow can dry the cables after spraying and scraping ring 21 at low temperature. The hot airflow can also heat the paint in the collection box 1 through heat conduction to keep the paint in good fluidity.

[0071] When the squeezing wheel 46 passes by, the squeezed elastic airbags 64 rebound, so that the paint in the collecting box 1 passes through the second conveying pipes 65 and the second one-way valves and enters the elastic airbags 64 .

[0072] When the first rotating cylinder 4 and the second rotating cylinder 5 need to be disassembled, the staff first disconnects the several quick connectors 63, and then controls the hydraulic cylinder 32 to extend through the controller, and the hydraulic cylinder 32 drives the driving motor 3, the first active bevel gear 31, and the second active bevel gear 33 to rise, so that the first active bevel gear 31 and the second active bevel gear 33 are separated from the first bevel gear ring 44 and the second bevel gear ring 52, and then the first rotating cylinder 4 and the second rotating cylinder 5 are removed, so as to repair or clean the related structures.

[0073] When the first rotating cylinder 4 and the second rotating cylinder 5 need to be assembled, the first rotating cylinder 4 is firstly sleeved on the outside of the first bearing 45 through the extrusion ring 6, and the first sliders are aligned with the first sliding grooves. Then, the second rotating cylinder 5 is sleeved on the outside of the second bearing 51, and the second sliders are aligned with the second sliding grooves. Then, the hydraulic cylinder 32 is controlled to contract by the controller, and the hydraulic cylinder 32 drives the driving motor 3, the first active bevel gear 31, and the second active bevel gear 33 to descend, so that the first active bevel gear 31 and the second active bevel gear 33 are meshed with the first bevel gear ring 44 and the second bevel gear ring 52. During the meshing process, the first active bevel gear 31 and the second active bevel gear 33 push the first bevel gear ring 44, the second bevel gear ring 52, the first rotating cylinder 4, the second rotating cylinder 5, the first sliders, and the second sliders move inward, squeezing the first springs and the second springs, so that the first active bevel gear 31 and the second active bevel gear 33 are meshed with the first bevel gear ring 44 and the second bevel gear ring 52 more closely. Finally, the quick connectors 63 are connected to complete the assembly. This makes the assembly and disassembly of the equipment more convenient and simple, and facilitates maintenance and cleaning.
