Description

Cable processing stranding machine with broken wire protect function Technical Field The invention relates to the technical field of stranding machines, in particular to a cable processing stranding machine with a broken wire protection function. Background A cable is an electrical energy or signal transmission device, typically consisting of several wires or groups of wires. The cables include power cables, control cables, compensation cables, shield cables, high temperature cables, computer cables, signal cables, coaxial cables, fire resistant cables, marine cables, mining cables, aluminum alloy cables, and the like. The cable stranding machine is designed for an adaptation groove of a cutting blade in a very critical patent in the wire and cable manufacturing industry aiming at cables with specific diameters, and if cables with different specifications (such as ultra-fine or ultra-thick cables) are processed, the position of the blade is required to be manually adjusted or the adaptation groove is required to be replaced, so that the operation efficiency is affected. In addition, the hooks are fixed in size and may not be compatible with production equipment that fills cables having large differences in density (e.g., high density cotton fibers versus low density cotton fibers). The main function of the cable is to twist a plurality of single wires of copper, aluminum or steel wires into a compact and round conductor according to a specific process rule (such as layer stranding, bundle stranding and the like) so as to increase the softness, the conductivity and the mechanical strength of the cable. The utility model discloses a prevent outage line cable stranded conductor equipment, including the text fagging, backup pad intermediate position rigid coupling has the protecting crust, the motor is installed to the lower part in the protecting crust, be connected with the gear on the output shaft of motor, the inside central point of protecting crust puts and rotates and install the hank dish, the hank dish is along circumference evenly distributed has a plurality of wire guide, is provided with wear-resisting plastics ring in every wire guide inside, through the use of rubber ring, wear-resisting plastics ring and ball ring, has effectively reduced the sinle silk and has avoided appearing sinle silk surface scratch, wearing and tearing condition at the frictional resistance of each contact point of import and export route. While the intended goal of twisting multiple wires to form a cable is essentially functionally achieved, significant drawbacks and deficiencies are exposed in addressing the two key issues of wire drag and wear. In the actual production operation process, due to the influences of various factors such as unstable equipment operation state, raw material quality difference and the like, the pulling force born by the lead often fluctuates, and meanwhile, the friction between the lead and each part of the equipment can also continuously increase the abrasion. When the pulling force is in an unstable state or the abrasion degree is continuously increased, the equipment cannot disperse or relieve local stress through an effective technical means, so that the phenomenon of stress concentration at key contact positions of wires, a doubling die and the like is difficult to avoid. Such stress concentrations, once exceeding the limits of tolerance of the wire itself, directly lead to wire breakage. More serious, once the single wire breaks, the device lacks a timely and accurate detection mechanism, can not sense and stop running rapidly, and still can continue twisting operation, so that poor gluing quality of the cable can be caused. Therefore, the cable of the twisted part can lack one or more wires, so that the internal structure of the cable is uneven, the twisting quality of the cable is greatly reduced, the overall performance of the cable is seriously affected, and even the potential safety hazard is buried for subsequent use.
