Description

Technical Field

[0001] This invention relates to the field of electrostatic spraying and powder coating machines, and more particularly to an automatic electrostatic spraying and powder coating machine for wires and cables. Background Technology

[0002] Wires and cables are wire products used to transmit electromagnetic energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated cores and their respective possible sheaths.

[0003] During the production process of wires and cables, the wires after being covered with insulation need to be oiled to protect the surface of the wires. After the oiling process, the wires after being covered with insulation need to be powdered to prevent the wires from sticking together and affecting the subsequent wire and cable manufacturing.

[0004] Before entering the electrostatic powder coating machine, wires and cables are usually rolled up and stored, resulting in varying degrees of dust on their exterior. Existing electrostatic powder coating machines lack a structure for cleaning the exterior of wires and cables. If wires and cables with dust on them are directly put into the electrostatic powder coating machine, the dust on their exterior can affect the adhesion of the powder and cause them to fall off, resulting in uneven oil and powder adhesion inside the electrostatic powder coating machine.

[0005] Therefore, it is necessary to provide an automatic electrostatic oil spraying and powder coating machine for wires and cables to solve the above-mentioned technical problems. Summary of the Invention

[0039] The working principle of the automatic electrostatic oil spraying and powder coating machine for wires and cables provided by this invention is as follows:

[0040] First, pass one end of the wire or cable through the cleaning tank 13 and position it between the cleaning cotton 31 on the fixed block 27 and the movable block 30. The movable block 30 and the fixed block 27 can be adjusted by rotating the threaded bolt 29 on the support block 28. Then, pass the wire or cable through the electrostatic powder spraying machine 1. After installation, simply start the water pump 24 to deliver the clean water inside the water tank 16 to the nozzle 25 through the connecting pipe 11. The water is then sprayed out through the nozzle 25 to initially rinse the outside of the wire or cable. After cleaning, the wire or cable moves into the electrostatic powder spraying machine 1 through the winding structure. When the wire or cable moves through the two cleaning cotton 31, the water on the outside of the wire or cable can be wiped dry and the external dust can be further cleaned. At the same time, the hot air blower 23 is started and hot air is slowly blown out through the air outlet 22 to simply dry the outside of the wire or cable. The cleaning water will flow into the water tank 16 through the drain pipe 15 below the collection tank 26.

[0041] Compared with related technologies, the automatic electrostatic powder coating machine for wires and cables provided by this invention has the following advantages:

[0042] Beneficial effects:

[0043] When dusty wires and cables need to be cleaned and coated with oil and powder in the electrostatic powder coating machine 1, first, pass one end of the wire or cable through the cleaning tank 13, positioning it between the cleaning cotton 31 on the fixed block 27 and the movable block 30. The position of the movable block 30 and the fixed block 27 can be adjusted by rotating the threaded bolt 29 on the support block 28. Then, pass the wire or cable through the electrostatic powder coating machine 1. After installation, simply start the water pump 24 to deliver clean water from the water tank 16 to the nozzle 25 through the connecting pipe 11. The water is then sprayed out through the nozzle 25 to initially rinse the exterior of the wire or cable. After cleaning, the wire or cable... The wires and cables move into the electrostatic powder coating machine 1 via the winding structure. As they pass through the two cleaning cotton pads 31, the external moisture of the wires and cables can be wiped dry and the external dust can be further cleaned. At the same time, the hot air blower 23 is started and hot air is slowly blown out through the air outlet 22 to simply dry the external surface of the wires and cables. The cleaning water will flow into the water tank 16 through the drain pipe 15 below the collection tank 26. This device allows the wires and cables to be cleaned inside the cleaning box 13 before entering the electrostatic powder coating machine 1, avoiding the impact of dust on the external surface of the wires and cables, which would affect the adhesion and cause uneven oil and powder adhesion.
