An emergency braking device for wire drawing and disconnection based on the principle of electromagnetism

Abstract

The invention relates to the technical field of cables, and discloses a cable wiredrawing wire breakage emergency braking device based on the electromagnetism principle. The cable wiredrawing wire breakage emergency braking device comprises a base. The upper portion of the base is fixedly connected with a shell. Winding wheels are movably connected in the shell. By movably connecting an output shaft of a motor with the winding wheels, the winding wheels synchronously rotate, a metal wire sequentially passes through a wire outlet wheel and the two winding wheels, a take-up wheel rotates, wiredrawing is completed, the metal wire penetrates through a coil, and the coil bears tensile force of the metal wire and is kept upward; when the metal wire is broken, the tensile force borne by the coildisappears, the coil moves downwards due to the gravity of a connection rod itself and makes contact with a contact to form a closed circuit, a magnetic field is formed around a metal bar, the metal bar is attracted to a magnet, the attraction force of the magnet and the metal bar is larger than the elastic force of a spring, a connection plate tilts upwards with the left end as the fulcrum, a braking plate is made to tilt upwards and finally makes contact with the take-up wheel, rotation of the take-up wheel is blocked, emergency braking is generated, and rotation is stopped.

Description

technical field [0001] The invention relates to the field of cable technology, in particular to an emergency braking device for cable wire breakage based on the principle of electromagnetism. Background technique [0002] The cable industry is the second largest industry in China after the automobile industry. With the continuous development of China's economy, China's cable industry has also developed rapidly. China has become the world's largest producer of wire and cable, and because cables are closely related to daily life, Therefore, every step in the production process is particularly important. [0003] The cable is usually a cable similar to a rope twisted by several wires or groups of wires. The cable is mainly composed of a conductive core, an insulating layer, a sealing sheath, and a protective covering.

Problems solved by technology

[0003] The cable is usually a cable similar to a rope twisted by several wires or groups of wires. The cable is mainly composed of a conductive core, an insulating layer, a sealing sheath, and a protective covering. Among these four parts, the conductive The wire core is generally made of high-conductivity materials, such as copper or aluminum, and these conductive cores also need to be drawn to make them elongated during the production process, and the drawing process will directly affect As far as the quality of the conductive wire core is concerned, the traditional wire drawing machine rotates multiple times during wire drawing and then winds the wire by the take-up reel to complete the wire drawing. However, due to improper operation or external factors during the wire drawing process, the alloy wire may break. And when the alloy wire cannot be continuously output and the take-up reel continues to rotate, it will eventually cause the alloy on the take-up reel to loosen easily. waste, and will affect the post-production process, resulting in unqualified cable quality, which needs to be reworked and remade, reducing work efficiency

[0004] In order to solve the above problems, the inventor proposed an emergency braking device for cable wire breakage based on the principle of electromagnetism, which has the advantage that the take-up reel can stop rotating when the alloy wire breaks, and effectively solves the problem of low work efficiency. Rework and remake the problem of being too cumbersome to ensure that the device is used during the wire drawing process, and by using the principle of electromagnetism to ensure the emergency braking effect and improve the quality of the cable
