Description

Technical Field

[0001] This utility model relates to the field of liquid filling machine technology, specifically to a splash-proof liquid filling machine. Background Technology

[0002] A liquid filling machine is a type of packaging machinery used to automatically and accurately fill liquid products into containers.

[0003] A liquid filling machine with publication number CN119118040A is characterized by optimizing the filling valve structure or integrating a simple buffer cavity, and using the principle of fluid dynamics to initially guide and decelerate the liquid flow, thereby achieving a more stable liquid delivery than traditional straight-through filling. Its technical advantages are reflected in improving the consistency and controllability of filling speed, and reducing droplet splashing and material waste to a certain extent.

[0004] However, this patented technology is still insufficient in the high-speed filling application scenarios targeted by this invention. The main problem is that the dissipation mechanism of the linear kinetic energy of the liquid flow is relatively simple and fails to completely convert or eliminate the direct impact of the high-speed liquid flow. This results in turbulence, rebound and splashing of the liquid flow at the end of the filling process, which has a certain impact on the filling efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a splash-proof liquid filling machine that solves the problem of direct impact and splashing from high-speed liquid flow.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a splash-proof liquid filling machine, comprising a filling gun and a water supply pipeline connected to the filling gun. The filling gun is a labyrinth gun, and at least three labyrinth-shaped guide units are continuously arranged inside it along the liquid flow direction. A rotating chamber is connected above the labyrinth gun. The liquid is given a rotational speed through the rotating chamber and enters the labyrinth gun tangentially, and flows through each of the labyrinth-shaped guide units in sequence. Each guide unit is composed of at least two of the following: a transverse semicircular plate, a transverse grid plate, a longitudinal semicircular plate, and a longitudinal grid plate, connected in an alternating manner.

[0007] Furthermore, the water supply pipeline includes a water pipe connected to the water inlet end of the rotating cavity. A metering mechanism and at least one valve are sequentially provided on the water pipe along the water inlet direction. A connecting ring is provided on the outer side of the bottom of the water pipe at the connection point with the rotating cavity. A connecting plate in a circular array is provided at the bottom of the connecting ring. A fixing ring is connected to the bottom of the connecting plate.

[0008] Furthermore, the metering mechanism is a metering piston structure, which includes a metering water pipe and a rubber piston disposed inside the metering water pipe. The rubber piston is connected to a piston rod, and the piston rod is connected to a piston cylinder on one side. The side wall of the metering water pipe is provided with metering grooves, and one end of the piston is connected to the water pipe.

[0009] Furthermore, the rotating cavity includes a rotating cylinder, the interior of which is provided with several obliquely downward-facing guide vanes arranged in a circular array. The lower ends of all the obliquely downward-facing guide vanes are slotted inward to form a lower water flow channel. The bottom of the rotating cylinder is connected to a filling trough through a slotted bottom, and the filling trough is connected to the top inlet of the labyrinth gun.

[0010] Furthermore, the maze gun includes a barrel, with a fixing ring connected to the outer side of the upper end of the barrel, and the maze-shaped guide unit disposed inside the barrel. The bottom of the barrel is conical, and the top is connected to the rotating cavity through a convex ring.

[0011] Furthermore, each of the maze-shaped guide units is composed of, from top to bottom, a horizontal semicircular plate, a horizontal grid plate, another horizontal semicircular plate, another horizontal grid plate, a vertical semicircular plate, a vertical grid plate, and another vertical semicircular plate connected in an alternating manner.

[0012] This utility model has the following beneficial effects: (1) After the liquid enters the rotating cylinder, under the forced action of the inclined guide vanes, the straight liquid flow is transformed into a high-speed rotating liquid flow, thereby converting the concentrated straight impact momentum into rotational momentum. Subsequently, this rotating liquid flow enters the gun barrel tangentially and continuously impacts the multi-layered labyrinth-type guide unit composed of the interlaced transverse semicircular plates, transverse grid plates, longitudinal semicircular plates and longitudinal grid plates inside. Each collision with the plate surface and the division through the grid continuously consumes and disperses the kinetic energy of the liquid flow, so that when it flows out of the bottom cone, the momentum has dropped to an extremely low level, thereby avoiding the violent impact of the liquid flow on the bottom of the container or the liquid surface, and eliminating splashing and violent turbulence.

[0013] (2) The smooth push of the piston structure of this utility model into the rotating chamber creates a gentle swirling flow, and then the labyrinth gun acts on the liquid flow. The whole process avoids turbulence, shearing and impact, thereby suppressing the generation of foam and ensuring that high viscosity liquids can be filled smoothly and evenly, which significantly improves the quality of the product and filling efficiency.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Please see Figures 1-6 As shown, this utility model is a splash-proof liquid filling machine, including a filling gun and a water supply pipeline connected to the filling gun. The filling gun is a labyrinth gun 1, which has at least three labyrinth-shaped guide units continuously arranged inside along the liquid flow direction. A rotating cavity 2 is connected above the maze gun 1; In this process, the liquid is given a rotational speed in the rotating chamber 2, enters the labyrinth gun 1 tangentially, and flows through each labyrinth-type guide unit in sequence. The rotating cavity 2 includes a rotating cylinder 201. Inside the rotating cylinder 201, there are several obliquely arranged guide vanes 202 arranged in a circular array and angled downwards. The lower ends of all the obliquely arranged guide vanes 202 are slotted inwards to form a lower water flow channel. The bottom of the rotating cylinder 201 is connected to the filling chute 204 via the slotted rotating bottom 203, and the filling chute 204 is connected to the top inlet of the maze gun 1. Please refer to Figure 3 , Figure 4 As shown, the liquid first enters the rotating cylinder 201 of the rotating chamber 2. When it flows through the circumferential array of inclined guide vanes 202, which are arranged at an angle downward, the flow direction is changed, thereby obtaining a uniform rotation speed and direction. Subsequently, this rotating liquid flow flows out through the lower water flow channel formed by the inward slots at the lower ends of all the inclined guide vanes, and enters the filling rotating tank 204 connected to it through the slotted rotating bottom 203. Finally, it is smoothly introduced into the top inlet of the labyrinth gun 1 in a tangential rotation manner. Each guide unit is composed of at least two of the following: a transverse semicircular plate 101, a transverse grid plate 102, a longitudinal semicircular plate 103, and a longitudinal grid plate 104, connected in an alternating manner. A single maze-type guide unit is composed of a horizontal semicircular plate 101, a horizontal grid plate 102, another horizontal semicircular plate 101, another horizontal grid plate 102, a vertical semicircular plate 103, a vertical grid plate 104, and another vertical semicircular plate 103 connected in an alternating manner from top to bottom. The maze gun 1 includes a barrel 11, a fixing ring 12 connected to the outer side of the upper end of the barrel 11, a maze-shaped guide unit disposed inside the barrel 11, the bottom of the barrel 11 is conical, and the top is connected to the rotating cavity 2 through a convex ring. Please refer to Figure 1 , Figure 2 As shown, the rotating fluid from the rotating cavity 2 first enters the barrel 11 through the convex ring at the top, and then sequentially impacts and flows through at least three consecutively arranged labyrinth-shaped guide units. Within a single guide unit, the fluid first encounters the transverse semicircular plate 101, whose arc surface initially blocks and guides the fluid to both sides. The falling fluid then passes through the transverse grid plate 102, where it is divided and dispersed into multiple fine streams by the grid. Immediately afterwards, the fluid encounters the transverse semicircular plate 101 and the transverse grid plate 102 arranged in another direction. After undergoing two changes in direction and division, the liquid flow then enters the longitudinal semicircular plate 103, forcing the liquid flow direction to deflect longitudinally. The subsequent longitudinal grid plate 104 further divides and slows down the liquid flow. Finally, after passing through another longitudinal semicircular plate 103 for final guidance and shaping, through the continuous collision, division and change of direction of multiple layers and grids arranged in multiple directions, the linear momentum and rotational kinetic energy of the liquid flow are fully consumed and dispersed, and finally become a smooth liquid flow, gently flowing out from the conical outlet at the bottom of the gun barrel 11. The water supply pipeline includes a water pipe 31 connected to the water inlet of the rotating cavity 2. A metering mechanism and at least one valve 34 are sequentially provided on the water pipe 31 along the water inlet direction. A connecting ring 32 is provided on the outer side of the bottom of the water pipe 31 at the connection point with the rotating cavity 2. A connecting plate 33 in a circular array is provided at the bottom of the connecting ring 32. A fixing ring 12 is connected to the bottom of the connecting plate 33. The metering mechanism is a metering piston structure 5, which includes a metering water pipe 54 and a rubber piston 53 installed in the metering water pipe 54. The rubber piston 53 is connected to a piston rod 52, and the piston rod 52 is connected to a piston cylinder 51 on one side. The side wall of the metering water pipe 54 is provided with metering grooves 55, one end of which is connected to the water pipe 31. Please refer to Figure 3 , Figure 5 , Figure 6 As shown, the liquid is first precisely controlled in the metering section. The operator pulls the piston rod 52 connected to the piston cylinder 51 to drive the rubber piston 53 in the metering water pipe 54 to move backward, drawing the liquid into the pipe. Its volume can be accurately observed and set through the metering grooves 55. Subsequently, under the control of the valve 34 on the water pipe 31, the piston rod 52 is pushed to move the rubber piston 53 forward, smoothly pressing a fixed amount of liquid into the water pipe 31. When the liquid flows through the pipeline, the entire upper structure is stably supported and positioned on the fixed ring 12 through the connecting ring 32 at the bottom of the water pipe 31 and the connecting plates 33 distributed in a circular array, thereby ensuring that the connection between the water outlet end of the water pipe 31 and the water inlet end of the rotating chamber 2 is accurate and stable.

[0019] When in use, first pull the piston rod 52 backward to drive the rubber piston 53 to retract inside the metering water pipe 54, and draw a predetermined volume of liquid according to the metering groove 55. Then close the valve 34 on the water pipe 31 near the water source. Pushing the piston rod 52 causes the rubber piston 53 to force the liquid into the rotating chamber 2 through the water pipe 31. The liquid first enters the rotating cylinder 201 and begins to rotate under the forced guidance of the inclined guide vanes 202, forming a vortex. It then flows into the slotted rotating bottom 203 and the filling rotating trough 204 through the circular groove-shaped water flow channel formed by the lower ends of all the guide vanes 202. The rotating liquid then enters the barrel 11 of the labyrinth gun 1 from the top and begins to flow through the multi-layered labyrinth-shaped guide unit composed of the transverse semi-circular plate 101, transverse grid plate 102, longitudinal semi-circular plate 103, and longitudinal grid plate 104. Each guide unit collides, divides, and changes the direction of the vortex, dispersing and consuming its momentum. Finally, the fully decelerated liquid flows out from the gently conical opening at the bottom of the barrel 11 and is injected into the container, completing a precise filling without impact or splash. The entire device is fixed to the fixed ring 12 by the connecting ring 32 and the connecting plate 33 to maintain structural stability.
