A constant tension wire storage device for cable extruder using magnetic effect

Abstract

The invention discloses a cable extruder constant tension wire storing device utilizing the magnetic effect. The structure of the cable extruder constant tension wire storing device utilizing the magnetic effect comprises an electric driving structure, a cable detecting device, a winding reel fixing frame, a magnetic force adjusting device and a winding reel body. According to the wire storing device, due to the fact that the cable detecting device is matched with the magnetic force adjusting device, after extruding of a cable is completed, the cable is fixed into the winding reel body to be wound, along with slow increasing of the diameter of a cable wound wire coil, the cable detecting device can perform detection in time and resistance is generated through the magnetic force adjusting device so that the rotating speed of a motor is gradually lowered, and it is guaranteed that the cable tension is kept unchanged; and the situation that after the coil diameter becomes large, the angular speed of a winding reel does not change, consequently the tension of the cable is too large, the wire diameter of a wire becomes small in a pulling manner and even the wire is broken in a pulling manner is avoided, and the winding quality of the wire storing device is effectively improved.

Description

technical field [0001] The invention relates to a wire storage device, in particular to a constant tension wire storage device for a cable extruder using magnetic effects. Background technique [0002] The cable is mainly composed of a certain number of cables in a certain way to form the cable core of the cable and the sheath outside the cable core. The optical cable is rewound by a reel, but the current technical considerations are not perfect, and it has the following disadvantages: After the cable is extruded, it is collected by the reel, and the diameter of the reel gradually increases when the reel winds the cable. The motor speed of the barrel remains unchanged, so when the diameter of the coil increases, the linear speed of the cable increases, and the tension will also increase accordingly. Excessive tension will easily cause the diameter of the wire to be thinned or even broken, reducing the production cost of the cable. quality. Contents of the invention [00...
