The utility model belongs to the technical field of burdening for
polyurethane resin
processing, and particularly relates to a burdening device for
polyurethane resin
processing, which comprises a base, a fixing ring is mounted on a foot stool, an annular
pipe is welded on the top side of the inner wall of an annular groove, a porcelain
pipe is mounted in the annular
pipe, a coil is wound on the porcelain pipe, and the inner wall of the annular groove is provided with an opening. A movable iron core is welded to the connecting block, multiple sets of springs are installed between the bottom side of the annular groove and the movable iron core, the other side of the connecting ring is connected with a cylinder body, magnetic force is generated by electrifying the coil, the movable iron core is attracted to vertically move upwards, the magnetic force on the coil disappears at the moment of switching of the positive
half cycle and the negative
half cycle of
sinusoidal current, and under the downward pulling force of the springs, the movable iron core moves upwards. The movable iron core is pulled to vertically move downwards, due to the fact that one period of
sinusoidal current is extremely short, the movable iron core drives the connecting ring to vibrate at
high frequency, the connecting ring drives the cylinder body to vibrate at
high frequency, and the cylinder body drives the viscous raw materials to vibrate at
high frequency, the viscous raw materials can be rapidly discharged, and the discharging efficiency can be improved.
