Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting raw material cutting, in particular to a single-machine dual asynchronous device. Background Art

[0002] Engraving machines are widely used in industries such as furniture decoration, mold industry and wooden crafts. The engraving heads of engraving machines all move in the direction established by the rectangular three-dimensional coordinate system. The single-phase two-value asynchronous motor is a common motor, and its working principle is based on the principle of electromagnetic induction. The current generated by the single-phase AC power supply flows in the coil to generate a rotating magnetic field. This rotating magnetic field will generate a magnetic flux in the stator. The size and direction of the magnetic flux change with time, and then drive the rotor to rotate under the action of the magnetic field. Since the single-phase asynchronous motor cannot start by itself, it is necessary to use a phase-splitting method to generate a second-phase current with a phase difference of nearly 90 degrees. This is usually achieved by having two sets of starting windings and working windings with a spatial position difference of 90 degrees on the stator of the motor, and combining the use of starting capacitors and running capacitors to shift the phase, and finally forming a rotating magnetic field.

[0003] Traditional engraving machines only allow repeated engraving of a single model for mold engraving. Multi-layer main materials or multi-knife cutting of products require two or more machines to cooperate in cutting, which not only takes up resources but also seriously affects the efficiency of processing and production. Therefore, a single-machine dual asynchronous device is proposed to solve the above problems. Utility Model Content
