Description

Technical Field

[0001] The utility model relates to the technical field of spindles for braiding machines, in particular to a spindle for a hose braiding machine. Background Art

[0002] A rotary braiding machine is a braiding device that forms a covering material around the periphery of a hose, and is particularly used to braid strands of materials such as steel, stainless steel, bronze, polyester, nylon, aramid, carbon fiber and similar materials around a substrate such as a hose or cable, and has been specifically used in forming pressure-resistant hydraulic hoses. In various configurations, these rotary braiding machines are characterized by two sets of spool carriers rotating in opposite directions along the same axis, and the strands released from one set of spool carriers are moved around one or more of the other set of spools to form a braid. The spindle is an essential component in the braiding machine.

[0003] The spindle structure of the American Kager Company mainly uses friction discs, ratchet discs and rollers to complete the unwinding and winding of the spindle (winding means braking the spindle, which means the spindle does not unwind); the existing application number is 201721267680.9, and the name is a utility model patent for a braiding machine external spindle braking mechanism. This structure is also used to complete the unwinding and winding of the spindle. Although the structure is somewhat different, when running at high speed, the friction disc frequently contacts the external spindle deck, and both the friction disc and the external spindle deck are very easy to wear; when running at high speed, the spindle relies on friction braking and is not sensitive. It is greatly affected by the amount of wire capacity of the spool and cannot be braked in time, which leads to easy wire breakage during work, affecting normal production efficiency. How to reduce the wear of the spindle and extend its service life, and avoid wire breakage caused by unwinding and unwinding is the object of study for those skilled in the art.
