Abstract
Description
Technical Field
[0001] This utility model relates to the field of aqueous preparation technology, and in particular to a filling device for aqueous preparation. Background Technology
[0002] The aqueous solution preparation filling device is a two-stage linkage filling equipment specifically designed to automatically, quantitatively, and leak-free inject high-viscosity aqueous solution liquids from the storage tank into containers of various sizes.
[0003] Traditional solutions typically use single-stage plunger pumps or gear pumps to directly extract liquid from the storage tank, completing the filling process by manually adjusting the valve opening or using simple time control. However, with the increasing demand for multi-specification packaging container production lines and continuous operation in high-cleanliness workshops, single-stage pumping methods have revealed problems such as low filling accuracy, slow height adaptation, susceptibility to dripping, and susceptibility to shearing and deterioration.
[0004] Therefore, this utility model provides a filling device for preparing aqueous solutions. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a filling device for preparing aqueous solutions.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a filling device for preparing an aqueous solution, comprising a storage tank and a primary regulating component, wherein the primary regulating component comprises a sliding support plate slidably connected to the outside of the storage tank, a worm gear rotatably connected to the top of the sliding support plate, a lead screw threadedly connected to the inside of the worm gear, a piston fixedly connected to the bottom of the lead screw, and a dispensing pipe fixedly connected to the bottom of the sliding support plate;
[0007] A secondary adjustment assembly includes a liquid delivery pipe fixedly connected to the bottom end of a first liquid delivery pipe, and a second liquid delivery pipe fixedly connected to the outside of the second liquid delivery pipe.
[0008] In a preferred embodiment, a motor is mounted on the top of the sliding support plate, and a transmission rod is fixedly connected to the drive end of the motor.
[0009] In a preferred embodiment, a worm is fixedly connected to the outer side of the transmission rod, and the worm and the worm wheel are meshed together.
[0010] In a preferred embodiment, a cylinder is fixedly connected to the top end of the second liquid separator, and a push rod is fixedly connected to the drive end of the first cylinder.
[0011] In a preferred embodiment, a push plug is fixedly connected to the bottom end of the push rod, and the outer side of the push plug is slidably connected to the inner wall of the second liquid separator.
[0012] In a preferred embodiment, the outer side of the piston is movably connected to the inner wall of the first liquid separator.
[0013] In a preferred embodiment, a second cylinder is installed at the top of the liquid storage tank, and the drive end of the second cylinder is fixedly connected to the sliding support plate.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] The motor of this invention drives the piston to slide back and forth in the sealing of the first liquid distribution tube through the linkage of the transmission rod, worm, worm wheel and lead screw, so as to achieve rapid liquid suction and push. The second cylinder drives the sliding support plate and related components to rise and fall as a whole to adapt to different bottle heights. The first cylinder drives the push stopper to slide in the second liquid distribution tube through the push rod to complete the micro-volume secondary filling. This design not only achieves high flow rate delivery to ensure filling efficiency through the first coarse adjustment mechanism, but also achieves high-precision micro-volume filling through the second fine adjustment mechanism. At the same time, the overall lifting structure enables rapid adaptation to different bottle sizes, effectively solving the problems of slow adaptation to different bottle heights, low filling accuracy and easy dripping.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a filling device for preparing an aqueous solution, including a storage tank 1 and a primary adjustment component 2. The primary adjustment component 2 includes a sliding support plate 21 slidably connected to the outside of the storage tank 1. A worm gear 22 is rotatably connected to the top of the sliding support plate 21. A lead screw 23 is threadedly connected to the inside of the worm gear 22. A piston 28 is fixedly connected to the bottom of the lead screw 23. A dispensing pipe 27 is fixedly connected to the bottom of the sliding support plate 21. A motor 26 is installed at the top of the sliding support plate 21. A transmission rod 25 is fixedly connected to the driving end of the motor 26. A worm 24 is fixedly connected to the outside of the transmission rod 25. The worm 24 and the worm gear 22 are meshed. The outside of the piston 28 is movably connected to the inner wall of the dispensing pipe 27. A cylinder 4 is installed at the top of the storage tank 1. The driving end of the cylinder 4 is fixedly connected to the sliding support plate 21.
[0028] The liquid storage tank 1, as the core liquid storage component, is used to store the aqueous liquid to be filled, providing a stable source of raw materials for the entire filling process. The sliding support plate 21, as the support carrier of the first-stage adjustment component 2, connects the liquid storage tank 1, worm gear 22, motor 26, and other components, and achieves vertical adjustment of the overall position through a "sliding connection". The worm gear 22 and worm 24 constitute the worm gear 22-worm gear 24 transmission mechanism, which converts the rotational power of the motor 26 into the linear motion of the lead screw 23. This prevents the lead screw 23 from moving on its own due to liquid pressure or gravity, ensuring the stability of the piston 28 position and improving the accuracy of the filling volume. The lead screw 23 moves up and down under the drive of the worm gear 22, driving the piston 28 to move in different directions. The liquid pipe 27 reciprocates. When it moves upward, a negative pressure is formed in the liquid pipe 27, drawing liquid from the storage tank 1. When it moves downward, the liquid is forced into the delivery pipe 31. The liquid pipe 27 serves as a primary liquid distribution channel, temporarily storing the liquid drawn from the storage tank 1, while providing a sealed sliding space for the piston 28. The motor 26 provides a power source, transmitting power to the worm gear 24 through the transmission rod 25, driving the entire worm wheel 22 and worm gear 24 mechanism to operate. The speed and distance of the lead screw 23 can be precisely controlled by adjusting the rotation speed, realizing automated quantitative filling, reducing manual intervention, and improving efficiency and consistency. The cylinder 4 drives the sliding support plate 21 to slide up and down, adjusting the overall height of the primary adjustment component 2.
[0029] like Figure 1 , Figure 3 and Figure 5 As shown, the secondary adjustment component 3 includes a liquid delivery pipe 31 fixedly connected to the bottom end of the first liquid delivery pipe 27, a second liquid delivery pipe 32 fixedly connected to the outside of the liquid delivery pipe 31, a cylinder 35 fixedly connected to the top end of the second liquid delivery pipe 32, a push rod 33 fixedly connected to the driving end of the cylinder 35, a push plug 34 fixedly connected to the bottom end of the push rod 33, and the outer side of the push plug 34 slidably connected to the inner wall of the second liquid delivery pipe 32.
[0030] The liquid delivery pipe 31 connects the first liquid distribution pipe 27 and the second liquid distribution pipe 32, delivering the liquid after primary adjustment to the secondary component, serving as an intermediate channel for liquid flow. The second liquid distribution pipe 32 serves as a secondary liquid distribution unit, enabling multi-channel liquid diversion and providing sliding space for the push plug 34. The cylinder 35 drives the push rod 33 to move the push plug 34 back and forth within the second liquid distribution pipe 32, precisely controlling the discharge volume of liquid in a single channel.
[0031] Working principle:
[0032] like Figure 1 - Figure 5 As shown:
[0033] In use: First, the motor 26 is energized and rotates, which in turn drives the transmission rod 25 to rotate synchronously, thereby driving the worm 24 to rotate around its axis; the worm 24 meshes with the worm wheel 22, thereby driving the worm wheel 22 to rotate on a fixed axis on the sliding support plate 21; the internal thread of the worm wheel 22 engages with the lead screw 23, thereby driving the lead screw 23 to move up and down axially, which in turn drives the piston 28 to slide back and forth in a sealing manner on the inner wall of the first liquid distribution tube 27; when the piston 28 moves upward, it creates a negative pressure in the inner cavity of the first liquid distribution tube 27, thereby driving the liquid in the storage tank 1 to be drawn into the first liquid distribution tube 27 for temporary storage; when the piston 28 moves downward, it creates a positive pressure, thereby driving the temporarily stored liquid through the delivery tube 31 to be pressurized to the second liquid distribution tube 32, realizing primary quantitative filling. When the height of the bottle changes, cylinder 24 first activates, which in turn drives the sliding support plate 21 to slide up and down along the outside of the liquid storage tank 1. This causes the entire primary adjustment assembly 2 to rise and fall synchronously, thereby driving the dispensing pipe 27, the delivery pipe 31, and the secondary adjustment assembly 3 to reach the required height. This enables rapid adaptation to different bottle sizes. In the secondary adjustment stage, cylinder 135 first extends and retracts, which in turn drives the push rod 33 to move up and down along the axis of the dispensing pipe 32. This causes the push plug 34 to slide and seal against the inner wall of the dispensing pipe 32. When the push plug 34 moves downward, it generates a secondary positive pressure, which in turn drives the liquid in the dispensing pipe 32 to be injected into the target container with a precise dosage, achieving micro-volume, high-precision secondary quantitative filling.
[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
