Description

A medium-sized high-speed braiding wrapping machine

technical field

The utility model relates to a medium-sized high-speed braiding and wrapping machine, which belongs to the technical field of wire and cable manufacturing equipment.

Background technique

In the current wire and cable industry, data communication cables, control cables, audio cables, etc. mostly use metal wire braided mesh shielding layers with a diameter of Φ0.08～Φ0.20, but the surface of the cables is only braided with metal mesh shielding layers. It cannot meet the high shielding requirements of some special communication and control cables. It is necessary to continuously wrap a thin metal tape on the outside of the cable mesh shielding layer to form a sealed metal tube to achieve better shielding effect. Because the medium-sized high-speed braiding machines used for metal braiding wires with this diameter are mostly vertical structures, the main shafts are vertically arranged, but the existing metal strip wrapping machines on the market have complex structures and large shapes, and the overall structure adopts a horizontal structure, and the main shafts are arranged horizontally. It is also equipped with a take-up and pay-off device and a traction device. In actual production, the cable needs to go through the weaving process (paying out - weaving - pulling - taking up and arranging) first, and then through the wrapping process (paying out - wrapping - pulling - taking up and arranging). The two processes cannot be integrated and can only be processed sequentially, resulting in low production efficiency and high labor intensity; the cables are easily damaged after being unwound, pulled, and retracted twice. There are a small number of horizontal medium-sized high-speed braiding machines on the market, the cables are braided horizontally, and the wrapping machine is arranged between the braiding and traction, which can realize the two processes of weaving and wrapping in one set-off, traction, and winding. The reason for the structural design of the medium-sized high-speed knitting machine is that the main shaft is arranged horizontally, and the rotary parts rotate on the vertical plane. The floor area is large, and the utilization rate of the workshop space of the cable production enterprise is low. Existing high-speed braiding machines and wrapping machines use the same power source for the host and traction, and adjust the braiding pitch and wrapping pitch by changing the gear ratio. The shielding performance requirements of high-shielding cables cannot be met.
