The polyurethane resin raw materials are put into the cylinder 14, and the motor 22 is operated to drive the stirring rod 18 to rotate. The stirring rod 18 drives the stirring blade 19 to rotate at a high speed. The stirring blade 19 drives the raw materials to mix and stir. At the same time, the stirring rod 18 drives the push plate 20 to rotate. The push plate 20 continuously scrapes the raw materials on the inner wall of the cylinder 14 to prevent the raw materials from accumulating on the inner wall of the cylinder 14. After the stirring is completed, the valve 24 is opened and the materials are discharged from the discharge pipe 23.

[0019] In the process of discharging the raw materials, the control panel 15 is used to pass the sinusoidal current through the wire into the coil 7. At this time, a magnetic force is generated around the coil 7, and the moving iron core 10 is attracted by the magnetic force and moves vertically upward until it contacts the annular tube 5. In one cycle of the sinusoidal current, the sinusoidal current switches between positive and negative half cycles. At the moment of switching between the positive and negative half cycles of the sinusoidal current, the sinusoidal current disappears. That is, in the positive and negative half cycles of the sinusoidal current, the coil 7 is energized and generates a magnetic force, which attracts the moving iron core 10 to move vertically upward.

Since one cycle of the sinusoidal current is extremely short, the moving iron core 10 vibrates at a high frequency, and the moving iron core 10 drives the connecting ring 13 to vibrate at a high frequency, and the connecting ring 13 drives the cylinder body 14 to vibrate at a high frequency, and the cylinder body 14 drives the viscous raw material to vibrate at a high frequency, so that the viscous raw material can be discharged quickly, which is beneficial to improving the discharge efficiency.

[0020] Working principle: in the process of mixing the polyurethane resin raw materials in the existing batching device, due to the viscosity of the polyurethane resin raw materials, the raw materials cannot be discharged quickly, resulting in low discharge efficiency. The polyurethane resin raw materials are put into the cylinder body 14 and operated by the motor 22 to drive the stirring rod 18 to rotate. The stirring rod 18 drives the stirring blade 19 to rotate at a high speed. The stirring blade 19 drives the raw materials to mix and stir. At the same time, the stirring rod 18 drives the push plate 20 to rotate. The push plate 20 continuously scrapes the raw materials on the inner wall of the cylinder body 14 to prevent the raw materials from accumulating on the inner wall of the cylinder body 14. After the stirring is completed, the valve 24 is opened and the material is discharged from the discharge pipe 23; in the process of discharging the raw materials, a sinusoidal current is passed into the coil 7 through the wire through the control panel 15. At this time, a magnetic force is generated around the coil 7, and the moving iron core 10 is attracted vertically upward by the magnetic force. Move until it contacts the annular tube 5. Within one cycle of the sinusoidal current, the sinusoidal current will switch between positive and negative half-cycles. At the moment of switching between the positive and negative half-cycles of the sinusoidal current, the sinusoidal current disappears, that is, within the positive and negative half-cycles of the sinusoidal current, the coil 7 is energized and generates magnetic force, attracting the moving iron core 10 to move vertically upward. At the moment of switching between the positive and negative half-cycles of the sinusoidal current, the sinusoidal current disappears, and the magnetic force on the coil 7 disappears. Under the downward pulling force of the spring 11, the moving iron core 10 is pulled to move vertically downward, that is, the moving iron core 10 reciprocates in the vertical direction. Since one cycle of the sinusoidal current is extremely short, the moving iron core 10 vibrates at high frequency, and the moving iron core 10 drives the connecting ring 13 to vibrate at high frequency. The connecting ring 13 drives the cylinder body 14 to vibrate at high frequency, and the cylinder body 14 drives the viscous raw material to vibrate at high frequency, so that the viscous raw material can be discharged quickly, which is beneficial to improving the discharge efficiency.
