[0032] Example 1:

[0033] See also Figure 1-5 The present invention describes the above technical solution in detail through the following embodiments:

[0034] A leak-proof filling device for liquid foundation production, comprising:

[0035] The fuselage 1 includes a frame 11, a material tank 12 is fixed to the top of the frame 11 by bolts, a driving assembly 3 is connected to the inner side of the top of the frame 11 through a lifting device, and the driving assembly 3 is connected to the material conveying device 2.

[0036] The material tank 12 is used to store liquid foundation. The material tank 12 can be a metal tank or a plastic tank.

[0037] The lifting device includes two lifting cylinders 13, and the top of the piston rod of the lifting cylinder 13 is fixed with a lifting frame 14 by bolts.

[0038] The lifting cylinder 13 is fixedly mounted on the inner side of the top of the frame 11 by bolts. By controlling the piston rod of the lifting cylinder 13 to extend or retract, the lifting frame 14 can be controlled to descend or rise.

[0039] The material conveying device 2 includes a material suction barrel 21, which is used to temporarily store materials. Feed one-way valves 22 are threadedly installed on the left and right sides of the bottom of the material suction barrel 21. The feed one-way valve 22 is connected to the material tank 12 through a hose. The bottom end of the material suction barrel 21 is connected to the filling component 4 through a discharge solenoid valve 23. A filling piston 24 is provided in the material suction barrel 21, and the filling piston 24 is connected to the drive component 3 through a piston rod 25.

[0040] The material extraction barrel 21 can be made of metal. A piston rod 25 extends upward through the top of the barrel 21. The piston rod 25 is securely connected to the filling piston 24 via screws. When subjected to an external force, the piston rod 25 drives the filling piston 24 to move along the axis of the material extraction barrel 21. It is important to note that when the filling piston 24 moves upward, the discharge solenoid valve 23 closes, and when the filling piston 24 moves downward, the discharge solenoid valve 23 opens.

[0041] The feed one-way valve 22 only allows materials to enter the material suction cylinder 21 from the outside.

[0042] When the filling piston 24 moves upward, the discharge solenoid valve 23 is closed. At this time, there is a negative pressure state under the filling piston 24, and the material is sucked out from the material tank 12 and enters the suction cylinder 21 through the hose and the feed one-way valve 22.

[0043] When the filling piston 24 moves downward, the material cannot be discharged from the feed one-way valve 22. At this time, the material is discharged from the discharge solenoid valve 23 and enters the filling component 4.

[0044] The discharge amount of the material is equal to the material suction amount of the suction cylinder 21. The material suction amount of the suction cylinder 21 is controlled by the upward movement distance of the filling piston 24. By controlling the upward movement distance of the filling piston 24, the discharge amount of the material can be controlled.

[0045] The driving assembly 3 includes a connecting frame 32, which is fixedly connected to the piston rod 25. The connecting frame 32 is connected to a power source assembly through a first screw 33. The power source assembly is used to drive the first screw 33 to rotate, thereby driving the connecting frame 32 to move up and down, and then driving the perfusion piston 24 to move up and down through the piston rod 25.

[0046] The middle portion of the connecting frame 32 is fixedly mounted on the top end of the piston rod 25 by means of bolts, and the connecting frame 32 is threadedly connected to the first screw rod 33 .

[0047] The connecting frame 32 is slidably connected to a guide slide 34 , the bottom end of the guide slide 34 is fixedly connected to a connecting plate 31 , the connecting plate 31 is rotatably connected to the bottom of the first screw 33 , and the piston rod 25 passes through the connecting plate 31 .

[0048] Two stopper sleeves 26 are symmetrically welded to the top of the pumping barrel 21. These stopper sleeves 26 are bolted to the connecting plate 31. When the first screw 33 rotates, the connecting frame 32, threadedly connected to the first screw 33 and slidably connected to the guide slide 34, moves along the axis of the first screw 33. Furthermore, because the connecting frame 32 is fixedly connected to the piston rod 25, rotation of the first screw 33 drives the piston rod 25 up and down through the connecting frame 32, thereby driving the filling piston 24 up and down.

[0049] The power source assembly is mounted on the top surface of the lifting frame 14 . The power source assembly includes a first motor 36 , and the output shaft of the first motor 36 is connected to the first screw 33 via a worm gear assembly 35 .

[0050] The worm gear assembly 35 utilizes a known self-locking worm gear and worm transmission. The first motor 36 utilizes a servo motor or a stepper motor and is bolted to the top surface of the lifting frame 14. The output shaft of the first motor 36 is fixedly connected to the worm of the worm gear assembly 35 via screws. The top of the first screw 33 extends through the connecting plate 31 and engages with the worm gear of the worm gear assembly 35.

[0051] After the first motor 36 is started, it can drive the worm to rotate through the output shaft, thereby driving the worm wheel to rotate, and then driving the first screw 33 to rotate. The rotation of the first screw 33 can drive the filling piston 24 to move up and down.

[0052] In addition, by controlling the lifting frame 14 to rise or fall, the first screw 33 and the guide slide 34 can be driven to move up and down, thereby controlling the up and down movement of the connecting plate 31, and then driving the up and down movement of the suction cylinder 21 through the limiting sleeve 26. The up and down movement of the suction cylinder 21 can drive the filling assembly 4 to move through the discharge solenoid valve 23.

[0053] The filling assembly 4 includes a filling nozzle 41 , and a sealing assembly is provided in the middle of the side of the filling nozzle 41 , and the sealing assembly is used to seal the filling bottle.

[0054] The pouring nozzle 41 is a metal tube, and the pouring nozzle 41 is threadedly connected to the outlet of the discharge electromagnetic valve 23. During pouring, the pouring nozzle 41 is inserted into the pouring bottle, and the material discharged from the discharge electromagnetic valve 23 can enter the pouring bottle from the pouring nozzle 41.

[0055] The sealing assembly includes a limit ring 42, which is welded and installed in the middle of the outer side of the filling nozzle 41. A pressure sensor 43 is pasted under the limit ring 42, and an elastic seal 44 is pasted under the pressure sensor 43. The pressure sensor 43 is used to detect the pressure exerted on the elastic seal 44.

[0056] The elastic sealing member 44 is made of a rubber member and is sleeved on the outside of the pouring nozzle 41. The elastic sealing member 44 is tapered as a whole.

[0057] When the lifting cylinder 13 drives the lifting frame 14 to move downward, the filling assembly 4 is driven downward through the material conveying device 2, so that the filling nozzle 41 is inserted into the filling bottle. At this time, the elastic sealing member 44 contacts the bottle mouth of the filling bottle to achieve the sealing of the filling bottle. The upward pressure applied by the bottle mouth of the filling bottle is transmitted to the pressure sensor 43, and the pressure sensor 43 detects the change in the pressure value. After the pressure on the elastic sealing member 44 reaches the standard value, the lifting cylinder 13 stops working and maintains the pressure.

[0058] When the operator of this embodiment uses the device, he starts the first motor 36 to drive the first screw 33 to rotate through the worm gear assembly 35, thereby driving the piston rod 25 to move upward through the connecting frame 32, and further driving the filling piston 24 to move upward.

[0059] When the filling piston 24 moves upward, the discharge solenoid valve 23 is closed, and a negative pressure state is formed below the filling piston 24. The material is sucked out from the material tank 12 and enters the material suction cylinder 21 through the hose and the feed one-way valve 22.

[0060] By controlling the number of revolutions of the first motor 36, the number of revolutions of the first screw 33 can be controlled, thereby controlling the movement distance of the connecting frame 32 and, in turn, the movement distance of the filling piston 24. By controlling the movement distance of the filling piston 24, the amount of material in the suction barrel 21 can be controlled.

[0061] After the height of the filling piston 24 reaches the set value, the first motor 36 stops working.

[0062] The piston rod of the control lifting cylinder 13 is extended, driving the lifting frame 14 to descend, thereby driving the suction barrel 21 to descend, and then driving the filling assembly 4 to descend, so that the filling nozzle 41 is inserted into the filling bottle, and the elastic seal 44 contacts the bottle mouth of the filling bottle to achieve the sealing of the filling bottle. Until the pressure sensor 43 detects that the pressure on the elastic seal 44 reaches the standard value, the lifting cylinder 13 stops working and maintains the pressure.

[0063] The first motor 36 is started again, and the first screw 33 is used to drive the connecting frame 32 to move downward, thereby driving the filling piston 24 to move downward through the piston rod 25, and at the same time the discharge solenoid valve 23 is opened.

[0064] Under the pressure of the filling piston 24, the material passes through the discharge electromagnetic valve 23, enters the filling nozzle 41, and finally enters the filling bottle. Until the filling piston 24 can no longer move, the first motor 36 stops working.

[0065] The piston rod of the lifting cylinder 13 is controlled to shorten, driving the lifting frame 14 to rise, so that the filling component 4 is separated from the filling bottle. At the same time, the discharge solenoid valve 23 is closed, and the first motor 36 is started to drive the filling piston 24 to rise, sucking the material into the suction barrel 21 to prepare for the next filling.

[0066] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
