Arc height protection device

Abstract

The invention discloses an arc height protection device. The device comprises a machine tool, a bottom plate fixedly arranged on the surface of the machine tool, a strong magnetic limiting plate located at the upper end of the bottom plate, a hinge device fixedly arranged together with the strong magnetic limiting plate, a contact rod connected with the hinge device, an alarm device, a PLC control panel and a power supply; a strong magnet is embedded in the strong magnetic limiting plate; one end of the contact rod is provided with a magnetic rod, and the other end of the contact rod is provided with a conductive rod; the magnetic rod and the strong magnet are magnetically attracted; the conductive rod is fixedly arranged together with the hinge device; the free end of the conductive rod extends out of the edge of the strong magnetic limiting plate; the hinge device is provided with a conductive contact; and the conductive contact is connected with the PLC control panel, the alarm device, the power supply and the machine tool through wires. According to the invention, in the paying-off process of the steel cord internal paying-off stranding machine tool, when the arc height of a steel cord is too large, the machine tool can give an alarm and stop in time, the phenomena of wire breakage and rope breakage of the steel cord are avoided, the product quality of the steel cord is ensured, and the loss is reduced.

Description

Technical field [0001] The present invention belongs to the technical field of arc high protection of steel cord twisted machine, and is specifically involved in an arc high protection device. Background technique [0002] The steel cord 机 Tool has an internal dispatched machine tool, placing a copper-plated wirewheel wheel on the inner cradle of the casing, copper-plated wires need to pass through the pulleys and fixed in both spindles during the machine. The flywheel plate on the spindle is achieved by a steel cord. When the production process needs to ensure that the steel cord is running on the two-flying wheel, it cannot be contacted by the machine to the machine, resulting in the production of steel cord Torsion, flat straightness is unqualified. [0003] At present, a copper rod is usually installed in the shortest part of the inner platen, and the steel cord is running on the flywheel pan, and the flywheel is rotated at high speed, and copper running on the flywheel disc....

Problems solved by technology

[0004] However, the above method has disadvantages: when the speed of the machine tool is too fast and the arc of the steel cord is too high, the contact time between the arc-shaped steel cord and the protective copper rod is extremely short, and sometimes the arc height alarm signal cannot be generated, and the arc height protection is unstable, resulting in A large number of substandard products increase the cost of production and operation
