Description

a pay-off machine

technical field

The invention relates to a pay-off mechanism, in particular to a pay-off machine, which belongs to the technical field of mechanical equipment.

Background technique

Electricity is an energy source powered by electrical energy. Invented in the 1870s, the invention and application of electricity set off the second industrialization climax. It has become one of the three scientific and technological revolutions in the world since the 18th century in human history. Since then, technology has changed people's lives. The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. It converts the primary energy of nature into electricity through mechanical energy devices, and then supplies electricity to various users through power transmission, transformation and distribution.

The transmission of electric energy, together with power transformation, power distribution, and power consumption, constitutes the overall function of the power system. Through power transmission, power plants and load centers that are far apart (up to thousands of kilometers) are connected, so that the development and utilization of electric energy go beyond geographical restrictions.

Transmission lines can be divided into overhead transmission lines and underground transmission lines according to their structural forms. The former consists of line towers, wires, insulators, etc., and is erected on the ground; the latter mainly uses cables and is laid underground (or underwater).

During the construction of overhead transmission lines, it is inevitable to use cable pay-off and take-up equipment.

The pay-off machine is a kind of wire and cable auxiliary equipment that is matched with the twisting machine and plays the role of pay-off. It is generally used in the production and construction of various cables. The wire on the reel can be conveyed evenly and straightly by the pay-off machine. to the winding mechanism for processing. The traditional pay-off machine mainly uses the motor to drive the wire reel to rotate. Because the size of the wire reel is different, during the continuous pay-off process of the wire reel, with the gradual increase of the coil diameter becomes smaller, the length of the wire released by the reel is not equal, and the uniform speed of the pay-off machine cannot be guaranteed, and during the pay-off process, due to the speed of the reel drive device and the speed of the drive device of the winding mechanism The tension of the wire will change, which will easily cause the accumulation of too many wire harnesses or the phenomenon of jamming when there are too few wire harnesses, which will affect the shearing of the later wire harnesses.
