Description

Technical Field

[0001] The utility model belongs to the technical field of filling equipment, and specifically relates to a submersible quantitative filling device. Background Art

[0002] Filling equipment is a machine used for filling liquids. Quantitative filling is achieved by controlling the volume of liquid filled into the packaging container for measurement and filling.

[0003] After retrieval, CN220350010U discloses an injection quantitative filling device, including a bottom plate. A support is fixedly installed on the upper surface of the bottom plate. The support is of an L-shaped structure. A liquid storage tank and a metering pump are fixedly installed at the top of the support. An electric telescopic rod is also fixedly installed at the top of the support. In the utility model, after filling is completed, the telescopic end of the electric telescopic rod drives the filling head to rise to a certain height. When the L-shaped push rod abuts against the inclined surface of the push block again, the liquid blocking disc will extend under the action of the elastic force of the spring rod to the lower part of the filling head to block the bottom of the filling head, so as to avoid the residual injection on the filling head affecting the dosage accuracy during the next use. If the injection drips, the dosage required for filling cannot be accurately controlled.

[0004] However, through the exploration of the inventor, it is found that this technical solution still has at least the following defects: in the above device, the bottom of the filling head is blocked by the provided liquid blocking disc, so that the residual liquid on the filling head will not drip into the packaging bottle, which is beneficial to accurately controlling the dosage required for filling. The dripping liquid is adsorbed by the adsorption cotton provided on the liquid blocking disc. However, the time consumed for filling work is usually long. Therefore, more liquid will drip during the filling process. In order to avoid liquid overflow, it is necessary to frequently replace the adsorption cotton during the filling work, which affects the working efficiency of the entire filling process.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

The following embodiments are used to illustrate the present utility model.

[0025] As Figures 1 to 5 shown

[0026] An under - liquid quantitative filling device includes a base 1. A support base 2 is fixedly installed on one side of the base 1. An installation plate 3 is fixedly arranged at the top of the support base 2. Installation holes are formed in the installation plate 3, and a spring rod 12 is fixedly arranged on the inner wall of the installation hole. A liquid - blocking plate 11 is fixedly arranged at the telescopic end of the spring rod 12. A cavity is arranged inside the liquid - blocking plate 11, and an aggregate box 18 is slidably arranged on the inner wall of the cavity. A push - pull plate 21 is fixedly connected to the outer wall of one side of the aggregate box 18. A rectangular movable opening 20 is formed on one side of the liquid - blocking plate 11. The push - pull plate 21 is located inside the rectangular movable opening 20. A circular blanking port 19 is formed in the middle of the top of the liquid - blocking plate 11. The circular blanking port 19 communicates with the cavity. A hydraulic cylinder 5 is fixedly installed on the top of the installation plate 3. The piston rod at the bottom of the hydraulic cylinder 5 extends below the installation plate 3. The bottom end of the piston rod of the hydraulic cylinder 5 is fixedly connected to a filling head 6. The filling head 6 is located directly above the liquid - blocking plate 11. The aperture of the liquid outlet hole of the filling head 6 is smaller than the inner diameter of the circular blanking port 19. When the filling head 6 and the liquid - blocking plate 11 are both reset to the initial position, the liquid - blocking plate 11 is located directly below the filling head 6. At this time, the liquid remaining on the filling head 6 can drip into the aggregate box 18 through the provided circular blanking port 19, achieving the effect of collecting the dripping liquid and avoiding the phenomenon of liquid overflow. After the entire filling work is completed, the aggregate box 18 is pulled by the provided push - pull plate 21 to move, so that the aggregate box 18 can move to the outside of the liquid - blocking plate 11 through the rectangular movable opening 20, facilitating people to process the liquid collected in the aggregate box 18.

[0027] In the specific implementation manner, an installation groove 7 is formed on the top of the base 1. A conveyor belt 9 is installed in the installation groove 7. Packaging bottles 10 are arranged on the top of the conveyor belt 9 at equidistant intervals. The packaging bottles 10 are conveyed to directly below the filling head 6 through the conveyor belt 9. Symmetrically arranged connecting plates 16 are fixedly connected to the outer wall of the piston rod of the hydraulic cylinder 5. The ends of both connecting plates 16 are fixedly connected to guide rods 17, and the bottom of the guide rods 17 is arranged in an inclined plane. A wedge - shaped block 13 is fixedly arranged at the telescopic end of the spring rod 12. The bottom ends of both guide rods 17 are in contact with the top of the wedge - shaped block 13. After the packaging bottle 10 is located directly below the filling head 6, the hydraulic cylinder 5 is started to drive the filling head 6 to move downward. The filling head 6 drives the two connecting plates 16 to move downward. The two connecting plates 16 drive the two guide rods 17 to move downward. During the downward movement of the two guide rods 17, the wedge - shaped block 13 can be pushed to move horizontally to one side. When the wedge - shaped block 13 moves horizontally, the telescopic end of the spring rod 12 can be driven to contract, so that the spring rod 12 can drive the liquid - blocking plate 11 to move horizontally to one side, avoiding hindering the downward movement of the filling head 6 until the filling head 6 moves downward and inserts into the bottle mouth of the packaging bottle 10.

[0028] Furthermore, a metering pump 8 is fixedly installed on the outer wall of the top of the mounting plate 3. The liquid inlet of the metering pump 8 is connected to an infusion tube 14. A liquid storage tank 4 is fixedly installed on the outer wall of the top of the mounting plate 3. The infusion tube 14 is communicated with the liquid storage tank 4. The liquid outlet of the metering pump 8 is connected to a liquid guide hose 15. The liquid guide hose 15 is communicated with the filling head 6. When the filling head 6 moves downward and inserts into the bottle mouth of the packaging bottle 10, the liquid in the liquid storage tank 4 can be quantitatively transported into the packaging bottle 10 through the filling head 6 by means of the arranged metering pump 8, infusion tube 14 and liquid guide hose 15, so as to realize the filling work. After one packaging bottle 10 is filled, the hydraulic cylinder 5 is started to reset the filling head 6 to the initial position. At the same time, the liquid blocking plate 11 is reset to the initial position under the action of the spring rod 12.

[0029] The implementation principle of the submersible metering filling device in this embodiment is as follows:

[0030] During specific use, the packaging bottle 10 is transported to directly below the filling head 6 through the conveyor belt 9. After the packaging bottle 10 is located directly below the filling head 6, the hydraulic cylinder 5 is started to drive the filling head 6 to move downward. The filling head 6 drives the two connecting plates 16 to move downward. The two connecting plates 16 drive the two guide rods 17 to move downward. During the downward movement of the two guide rods 17, the wedge-shaped block 13 can be pushed to move horizontally to one side. During the horizontal movement of the wedge-shaped block 13, the telescopic end of the spring rod 12 can be driven to contract, so that the spring rod 12 can drive the liquid blocking plate 11 to move horizontally to one side, avoiding hindering the downward movement of the filling head 6 until the filling head 6 moves downward and inserts into the bottle mouth of the packaging bottle 10. Then, the liquid in the liquid storage tank 4 can be quantitatively transported into the packaging bottle 10 through the filling head 6 by means of the arranged metering pump 8, infusion tube 14 and liquid guide hose 15, so as to realize the filling work. After one packaging bottle 10 is filled, the hydraulic cylinder 5 is started to reset the filling head 6 to the initial position. At the same time, the liquid blocking plate 11 is reset to the initial position under the action of the spring rod 12, so that the liquid blocking plate 11 is located directly below the filling head 6. At this time, the liquid remaining on the filling head 6 can drip into the aggregate box 18 through the arranged circular blanking port 19, realizing the collection effect of the dripping liquid and avoiding the phenomenon of liquid overflow. After the whole filling work is completed, the aggregate box 18 is pulled to move through the arranged push-pull plate 21, so that the aggregate box 18 can move to the outside of the liquid blocking plate 11 through the rectangular movable port 20, facilitating people to process the liquid collected in the aggregate box 18.
