The voltage structure of the liquid packaging electromechanical source mainly includes the following parts: winding: the winding of the power transformer. In the transformer of the liquid packaging machine with low power, enameled wire is used for winding. This kind of wire has low price and large duty cycle. Each winding adopts layered arrangement and multi-layer winding, and yellow wax silk cloth is sandwiched between the windings for insulation.
The order of each winding is generally around the primary coil first, then around the high voltage coil, and then around the filament coil, so that the high voltage coil is sandwiched in the middle, which is convenient for insulation and can avoid breakdown with the iron core. The filament coil of vacuum packaging machine and automatic vacuum packaging machine is wrapped in the outer layer for easy heat dissipation.
Iron core: shell iron core is used in vacuum packaging machine and tensile film packaging power transformer. Iron chip is made of whole silicon steel sheet. After punching, burrs should be removed and annealed to remove stress and improve magnetic conductivity of iron chip, which is conducive to reducing iron loss and reducing temperature rise.
Other parts: food packaging machine, vacuum packaging machine transformer is the basic components of winding and iron core, other parts and cover shell, fixing bolts, nuts and so on. The housing is used to protect the windings from mechanical damage, and nuts and bolts are used to secure the iron core to reduce reluctance and electromagnetic sound.
