Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coating machines, in particular the technical field of rolling brush coating type coating machines. BACKGROUND

[0002] Cables are wires used for transmitting and distributing electric energy, usually including one or more insulated cores (each insulated core can be individually coated with an inner sheath) and an outer sheath coated on the outside of each insulated core, which can be applied to urban underground power grids, power station outgoing lines, internal power supply of industrial and mining enterprises, and underwater power transmission lines across rivers and seas.

[0003] Cables are mainly completed through three processes of drawing (forcing metal to pass through a die under external force to compress the cross-sectional area of the metal to the required size), stranding (interweaving two or more conductors together in a specified direction), and coating (coating the required material on the outside of the conductor). Among them, coating includes extrusion, longitudinal wrapping, winding, and dipping, which can assist cables to achieve special performance requirements, and dipping mainly refers to coating insulating paint and fireproof paint on the outside of the cable.

[0004] The existing cable dipping equipment usually selects to directly guide the cable into a liquid tank containing paint by using a guide roller, and then guides the cable out of the liquid tank containing paint by using a guide roller again after the cable is completely immersed in the paint, such as the utility model patent disclosed in the utility model patent with the publication number CN210896784U. However, such a device may cause the coating on the surface of the cable to be too thick, thereby causing waste of paint. In addition, there are also devices that use dripping coating combined with scraping to coat paint, such as the utility model patent disclosed in the utility model patent with the publication (publication) number CN202290455U. However, on the one hand, the dripping coating from top to bottom cannot guarantee that each point on the surface of the cable can fully contact the paint, and on the other hand, after working for a long time in a high-temperature environment, the top inner wall of the device is prone to preliminary condensation of the paint, and the preliminarily condensed paint may directly drip onto the surface of the cable that has been dipped in paint under the action of gravity and further condense in the subsequent drying environment, causing further decline in the uniformity of the paint coating. SUMMARY

[0008] Preferably, the brush coater further comprises elastic sheets, the silk screen cylinder is coaxially sleeved outside the sponge cylinder, and a plurality of the elastic sheets are respectively arranged around the two ends of the brush coating channel and press the sponge cylinder by elastic force.

[0009] Preferably, the brush coater further comprises inner rings and outer rings, the two ends of the silk screen cylinder are respectively coaxially fixed with the inner rings, the outer rings are respectively threadedly connected outside the two inner rings, one end of each of the elastic sheets is fixed with one of the outer rings and the other end respectively extends into the brush coating channel and clamps the sponge cylinder together with the inner ring.

[0010] Preferably, the two outer rings are respectively provided with inward turned edges at one end away from the silk screen cylinder, and the two inner rings are respectively supported by the inward turned edges of the connected outer rings at one end away from the silk screen cylinder.
