The rotating arm mechanism includes a rotating arm located in the radial direction of the rotating arm disk, and one end of the rotating arm is hinged to the rotating arm disk. Connected, and the other end of the rotating arm is provided with a roller; there is a friction surface that cooperates with each other between the friction disc Ⅰ and the friction disc Ⅱ; a spring and a sliding guide mechanism are provided between the friction disc Ⅱ and the housing; Groove, and the bottom of the groove is provided with an adjustment mechanism for adjusting the pre-pressure exerted by the spring on the friction disc II.

Description

technical field [0001] The invention relates to a cable winding device, in particular to an adjustable self-adaptive winding reel device. Background technique [0002] The existing winding reels generally include a winding reel main body, a central through hole is set in the middle of the winding reel main body, and a winding groove is arranged on the outer peripheral wall of the winding reel main body. The reel can realize the purpose of winding or paying off the wire. Of course, when paying out the wire, the pulling wire can also be directly used to drive the winding reel to rotate to realize the purpose of paying out the wire. Although the existing winding reel can meet the requirements of use to a certain extent, in the process of use, there is often a problem that the rotating speed of the winding reel does not match the speed of winding or paying off the wire. For example, when winding the wire, suddenly Applying a large torque to the winding reel will cause the speed...

Problems solved by technology

Although the existing winding reel can meet the requirements of use to a certain extent, in the process of use, there is often a problem that the rotating speed of the winding reel does not match the speed of winding or paying off the wire. For example, when winding the wire, suddenly Applying a large torque to the winding reel will cause the speed of the winding reel to increase suddenly, which will cause its speed to exceed the speed required for winding the wire, and then apply a large traction force to the wire, which exceeds the speed of the wire. If it is within the bearing range, the quality of the wire will be damaged or even disconnected; if a large instantaneous pulling force is applied to the wire when paying off the wire, the speed of the driving reel will suddenly increase, which exceeds the limit of the wire. The required speed, so that the excess wire will be piled up on the ground, which is not conducive to safe production; and in the process of unwinding, it is often necessary to apply a pre-added traction to the wire, and the existing winding reel cannot meet the requirements.
