When using the filling machine, it can quantitatively fill the packaging container according to the capacity of the packaging container. The filling machine usually needs to be equipped with a material measuring mechanism and a pumping device.

The lower end of the outer part of the support bracket 8 is fixedly installed with a fixed circular plate 9. The interior of the fixed circular plate 9 and the quantitative pumping cylinder 6 are both installed with a lifting connecting shaft 13 that slides up and down through a slot. The installation of the lifting connecting shaft 13 can limit the fixed circular plate 9. At the same time, when the fixed circular plate 9 moves longitudinally, the fixed circular plate 9 The piston plate 18 can be driven to move longitudinally by the lifting connecting shaft 13 to ensure the pumping capacity of the device. The piston plate 18 is fixedly installed at the lower end of the lifting connecting shaft 13. The piston plate 18 is installed to cooperate with the driving screw 10 and the quantitative pumping cylinder 6. When the driving screw 10 rotates, the driving screw 10 can drive the longitudinal moving circular plate 12 and the lifting connecting shaft 13 to move longitudinally, thereby causing the piston plate 18 to move longitudinally, thereby changing the air pressure inside the quantitative pumping cylinder 6, thereby ensuring that the liquid material can be sucked into the quantitative pumping cylinder 6, thereby realizing the pumping of the liquid material and enhancing the practicality of the device;

The feeding pipe 20 penetrates into the interior of the quantitative pumping cylinder 6 and the liquid material storage box 14. The interior of the feeding pipe 20 is rotatably installed with a magnetic feed flip plate 21. The installation of the magnetic feed flip plate 21 can make the piston plate 18 move upward. The liquid material can push the magnetic feed flip plate 21 to flip, so that the liquid material can be sucked into the quantitative pumping cylinder 6, and the amount of liquid material sucked is proportional to the longitudinal movement of the piston plate 18 driven by the driving screw 10 through the longitudinal movable circular plate 12 and the lifting connecting shaft 13. The staff can adjust the amount of liquid material according to production needs. By adjusting the stroke of the driving motor 11 to drive the driving screw 10 to rotate, the amount of liquid material sucked into the quantitative pumping barrel 6 can be controlled with high precision, ensuring the high precision of the device, and thus the device does not need to be additionally installed with some material measuring mechanisms, thereby achieving the purpose of reducing the working energy consumption of the filling machine, thereby reducing the use cost of the filling machine. Filling pipes 15 are fixedly installed on both sides of the lower end surface of the quantitative pumping barrel 6, and a magnetic discharge flip plate 22 is installed inside the filling pipe 15 through a hinge rotation. The installation of the magnetic discharge flip plate 22 can make the device in the pumping process. Under the action of air pressure, the magnetic discharge flip plate 22 is in a closed state, ensuring that the liquid material can stably enter the interior of the quantitative pumping barrel 6. When the device is in the pumping state, the magnetic discharge flip plate 22 is in an open state, and at this time, the magnetic feed flip plate 21 is in a closed state under the action of the pressure of the liquid material, ensuring that the liquid material can be stably discharged from the device.

Connecting injection pipes 7 are installed on both sides of the upper end surface of the liquid material storage box 14. The connecting injection pipe 7 is welded to the liquid material storage box 14. The lower end of the driving screw 10 is rotatably connected to the fixed circular plate 9 through a bearing, and three lifting connecting shafts 13 are provided.

[0028] Working principle: When in use, the staff installs the device in a dust-free constant temperature workshop, and then the staff adds the liquid material into the liquid material storage box 14 through the connecting injection pipe 7, and then drives the motor 11 to drive the driving screw 10 to rotate, thereby making the fixed circular plate 9 cooperate with the lifting connecting shaft 13 to move longitudinally, so that the piston plate 18 at the lower end of the lifting connecting shaft 13 moves upward. At this time, when the piston plate 18 moves upward, the pressure inside the quantitative pumping cylinder 6 decreases, and the external air pressure pushes the magnetic discharge flip plate 22, so that the magnetic discharge flip plate 22 is in a closed state. At the same time, the magnetic feed flip plate 21 is opened, and the liquid material inside the liquid material storage box 14 enters the quantitative pumping cylinder 6. In this process, the conveying line bracket 1 drives the conveying roller 2 Rotate, so that the material conveying belt 3 drives the container bottle 4 to move to the bottom of the filling pipe 15, and then the driving motor 11 drives the driving screw 10 to rotate in the opposite direction, thereby making the fixed circular plate 9 cooperate with the lifting connecting shaft 13 to move longitudinally, so that the piston plate 18 at the lower end of the lifting connecting shaft 13 moves downward, so that the piston plate 18 squeezes the liquid material. At this time, the magnetic feed flip plate 21 is closed, and the magnetic discharge flip plate 22 is opened, and the liquid material is squeezed out of the filling pipe 15 and discharged into the container bottle 4. The installation of the lifting connecting shaft 13 in this device can limit the fixed circular plate 9. At the same time, when the fixed circular plate 9 moves longitudinally, the fixed circular plate 9 can drive the piston plate 18 to move longitudinally through the lifting connecting shaft 13 to ensure the pumping capacity of the device. The piston plate 18 is installed to cooperate with the driving The movable screw 10 and the quantitative pumping cylinder 6 can make the driving screw 10 drive the longitudinal moving circular plate 12 and the lifting connecting shaft 13 to move longitudinally when the driving screw 10 rotates, thereby making the piston plate 18 move longitudinally, thereby changing the air pressure inside the quantitative pumping cylinder 6, thereby ensuring that the liquid material can be sucked into the quantitative pumping cylinder 6, thereby realizing the pumping of the liquid material and enhancing the practicality of the device. The installation of the magnetic feed flip plate 21 can make the liquid material push the magnetic feed flip plate 21 to flip when the piston plate 18 moves upward, so that the liquid material can be sucked into the quantitative pumping cylinder 6, and the amount of liquid material sucked is proportional to the longitudinal movement of the piston plate 18 driven by the driving screw 10 through the longitudinal moving circular plate 12 and the lifting connecting shaft 13. The operator can adjust the stroke of the driving motor 11 to drive the driving screw 10 to rotate according to production needs, so as to realize high-precision control of the amount of liquid material sucked into the quantitative pumping barrel 6, ensure the high precision of the device, and thus make the device do not need to install some additional material measuring mechanisms, thereby achieving the purpose of reducing the working energy consumption of the filling machine, thereby reducing the use cost of the filling machine. The installation of the magnetic discharge flip plate 22 can make the device in the pumping process. Under the action of air pressure, the magnetic discharge flip plate 22 is in a closed state, ensuring that the liquid material can stably enter the quantitative pumping barrel 6. When the device is in the pumping state, the magnetic discharge flip plate 22 is in an open state, and at this time, the magnetic feed flip plate 21 is in a closed state under the action of the pressure of the liquid material.Ensure that liquid materials can be discharged from the device stably.
