[0031] The anti-solidification mechanism includes a liquid dispensing pipe 28, a limit box 29, a valve rod 30, a bevel gear set 31, a positioning shaft 32 and a reciprocating screw rod 33.

[0032] When the utility model is in use, it is first necessary to control the amount of liquid drawn according to the size of the sub-filling bottle. At this time, it is first necessary to engage the support block 25 and the pressure sensor 26 into the T-shaped slot 24 corresponding to the scale position indicated by the appropriate scale plate 27. After adjustment, the liquid drawing process begins. At this time, it is first necessary to turn on the drive motor 10. When the drive motor 10 is turned on, it will automatically drive the limit shaft 11 to rotate and then drive the drive gear 12 to rotate. Subsequently, the rotation of the drive gear 12 will automatically drive the driven gear 13 to rotate and then drive the limit screw 14 to rotate. When the limit screw 14 rotates When the second piston pad 16 moves, it will automatically drive the first piston pad 15 and the second piston pad 16 to move. When the first piston pad 15 slides upward on the inner wall of the first piston cylinder 3, the one-way liquid inlet valve 18 is automatically opened. At the same time, the adhesive inside the liquid storage barrel 1 is transported to the first piston cylinder 3 for storage through the liquid extraction pipe 17. When the second piston pad 16 moves, it will automatically drive the indicator arrow 22 to move. When the indicator arrow 22 hits the pressure sensor 26 during the movement, the pressure sensor 26 will automatically control the drive motor 10 to stop operating, thereby stopping the liquid extraction. When the first piston pad 15 slides downward on the inner wall of the first piston cylinder 3, the valve inside the liquid dispensing tube 28 will automatically open, and the adhesive stored in the first piston cylinder 3 will be discharged. At the same time, the limit shaft 11 will also synchronously drive the driving sprocket 19 to rotate when it rotates. When the driving sprocket 19 rotates, it will automatically drive the driven sprocket 20 and the chain 21 to transmit. Then, the driven sprocket 20 will automatically drive the stirring shaft 6 to rotate when the stirring shaft 6 rotates. When the stirring shaft 6 rotates, it will automatically drive the stirring blade 7 and the first scraper 8 to rotate. When the valve is opened, the valve rod 30 is driven. When rotating, the valve stem 30 automatically rotates to drive the bevel gear set 31 to rotate, and then the rotation of the bevel gear set 31 will drive the positioning shaft 32 to rotate and then drive the reciprocating screw 33 to rotate. When the reciprocating screw 33 rotates, it will automatically drive the sliding block 34 to move and then drive the second scraper 35 to move to the top of the inner wall of the liquid outlet filling tube 28. When the valve is closed to drive the valve stem 30 to rotate in the opposite direction, the principle is the same as above, but the second scraper 35 slides downward on the inner wall of the liquid outlet filling tube 28, and scrapes a small amount of adhesive attached to the inner wall of the liquid outlet filling tube 28 into the interior of the filling bottle.
