When the pneumatic motor telescopic rod 12 moves upwards, the pump connecting rod 213 and the piston rod 207 are pulled to move upwards, the second plunger 216 is separated from the plunger seat 217, so that the colloid channels of the C area and the B area are opened, the piston 206 moves upwards to seal the cavity, the colloid in the C area of the cavity is pushed to flow upwards, and the colloid flows into the B area of the cavity through a gap between the second plunger 216 and the plunger seat 217 and an 8-shaped hole of the second plunger 216; simultaneously, the trend of the upward movement of the pump connecting rod 213 makes the lower end of the waist of the pump connecting rod abut against the lower end of the first plunger 214, so that the colloid flow channels between the area B and the area A of the cavity are closed, and the colloid in the area A is pushed into the connecting block 209 and the colloid conveying pipeline by the synchronous upward movement of the two.
When the pneumatic motor telescopic rod 12 moves downwards, the pump connecting rod 213 and the piston rod 207 are pushed to move downwards, the lower end of the second plunger 216 is abutted against the plunger seat 217, so that the colloid channels of the C area and the B area are closed, and the colloid in the B area is prevented from flowing backwards; at this time, the lower end of the waist of the pump connecting rod 213 is separated from the lower end of the first plunger 214, so that the gel channels of the area a and the area B are opened, and the pump connecting rod 211 is larger than the piston rod 207, and the downward movement of the pump connecting rod compresses the volumes of the gel channels of the area a and the area B of the cavity, so that the gels in the two areas are extruded upwards into the connecting block 209 and the gel conveying pipeline 212; at the same time, the piston 206 moves downwards, opening the cavity C, which is again filled with glue in the glue barrel, as the glue pressing disc 3 always presses the glue barrel, maintaining pressure.
Therefore, no matter the upward stroke or the downward stroke, the colloid is always in a pumping state, so that the colloid pumping efficiency is improved, and the colloid pumping process is stable; because the plunger motion stroke is small, the service life of the plunger is prolonged, the plunger can be independently replaced, and the maintenance cost is low. Meanwhile, the pneumatic motor is adopted to realize the reciprocating motion of the rubber pump, compared with an electric control moving part, the pneumatic motor has the advantages that the damage of a power part caused by overload or moisture is avoided, and the maintenance cost is reduced.
