Talcum powder coating device for cable

Abstract

The invention provides a talcum powder coating device for a cable. According to the device, by arranging a sealing cover for sealing a first feeding inlet and a second feeding inlet, talcum powder ina powder box is prevented from leaking out through the first feeding inlet and the second feeding inlet, the practicability of the device is improved, by arranging a receiving trough for receiving talcum powder overflowing from a cable outlet along with the cable, the situation that talcum powder falls around and pollutes the environment is avoided, and the environment protection property of the device is improved; and when the cable needs to be coated with talcum powder, the cable is extended into the powder box through a cable inlet and further extended out through the cable outlet, thus, the purpose of coating the cable with talcum powder is achieved, operation is simple, through rotation of a motor, a driving gear is driven to rotate, then a first driven gear and a second driven gear are driven to rotate, first stirring blades on a first stirring rotary shaft and second stirring blades on a second stirring rotary shaft are further driven to rotate so as to stir talcum powder in thepowder box, and the cable coating effect is ensured.

Description

technical field [0001] The invention relates to the field of coating devices, in particular to a talcum powder coating device for cables. Background technique [0002] In the manufacturing process of power cables, glue and adhesion are prone to occur between the insulated core and the outer sheath, especially when the outer sheath is extruded outside the insulated core or stranded conductor by an extruder. The glue and adhesion not only seriously affect the flexibility of the cable, but also affect the subsequent processing and laying installation of the cable. create a safety hazard. [0003] The industry usually chooses to coat the insulated wire core with talcum powder as a cable release agent to facilitate the separation of the wire core and the sheath. The existing talcum powder coating step is usually realized by using a powder passing device, which includes a powder box containing talcum powder, and the wire to be powdered is directly drawn from one end of the powde...

AI Technical Summary

Problems solved by technology

However, because talcum powder has a certain degree of adhesion and solid plasticity, when the insulated wire core passes through the talcum powder, a cavity will be formed in the talcum powder brought out by the insulated wire core, and part of the cavity will collapse under the action of gravity, making the subsequent wires The core can still be coated with talcum powder, resulting in uneven talcum powder contamination of the insulated wire core and poor powder coating effect. When extruding, it will cause the phenomenon of wrapping on the wire surface, which will seriously affect the appearance and quality of the power cable, and reduce its use effect and service life
