Description

Technical Field

[0001] The utility model relates to the technical field of flame-retardant cable production and processing, in particular to a filling device for flame-retardant cable production. Background Art

[0002] Flame-retardant cables refer to cables that, under specified test conditions, can be burned by the sample. After the test fire source is removed, the spread of the flame is limited to a limited range, and the residual flame or residual burning can be extinguished within a limited time. The basic characteristics are: in the event of a fire, it may be burned and unable to operate, but the spread of the fire can be prevented. In layman's terms, if the wire catches fire, the burning can be limited to a local range, preventing it from spreading, thus saving various other equipment and avoiding greater losses.

[0003] Therefore, a flame retardant filler needs to be filled between the outer sheath protective layer of the flame retardant cable and the insulating layer of the inner conductive core of the cable. When filling the flame retardant filler, a filling device is required.

[0005] However, the filling device for producing highly flame-retardant cables still has the following problems compared with the prior art:

[0006] The filling device for the production of highly flame-retardant cables drives the gear to rotate through the driving part, thereby driving the wrapping part to rotate on the gear ring, and wraps the flame-retardant material inside the cable. During the entire filling process, the flame-retardant material falls from the material barrel by its own gravity and is wrapped. Once the flame-retardant material falls unevenly, it will affect the filling effect, resulting in uneven filling, thereby affecting the quality of the produced flame-retardant cable.

[0007] Therefore, the present application proposes a filling device for flame retardant cable production to solve the above problems. Utility Model Content
