Adjustable self-adaptive wire spool device

Abstract

An adjustable self-adaptive wire spool device comprises a wire spool body. The wire spool body is provided with a center through hole. The peripheral wall of the wire spool body is provided with a wire winding groove. A rotary shaft is arranged in the center through hole of the wire spool body in a sleeved mode. A self-adaptive friction mechanism is mounted on the rotary shaft and comprises a shell. The shell is internally provided with a rotary arm disk, a friction disk I and a friction disk II. The friction disk I is located between the rotary arm disk and the friction disk II. Rotary arm mechanisms are arranged on the side face of the side, facing the friction disk I, of the rotary arm disk. Each rotary arm mechanism comprises a rotary arm located in the radial direction of the rotary arm disk, one end of each rotary arm is in hinged connection with the rotary arm disk, and the other end of each rotary arm is provided with a rolling wheel. Friction surfaces matched with each other are arranged between the friction disk I and the friction disk II. A spring and a sliding guide mechanism are arranged between the friction disk II and the shell. The shell is provided with a groove. The bottom of the groove is provided with an adjusting mechanism used for adjusting pre-pressure exerted on the friction disk II by the spring.

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.
