[0053] Figure 1 This is a first structural schematic diagram of the bottled liquid filling system provided in the first embodiment of this application; Figure 2 yes Figure 1 A second structural schematic diagram of a bottled liquid filling system; Figure 3 yes Figure 1 A first structural schematic diagram of the liquid filling device 100 in the middle;

[0054] Figure 4 yes Figure 3 A second structural schematic diagram of the liquid filling device 100; Figure 5 yes Figure 3A schematic diagram of the first structure of the liquid filling device 100 after removing the fixing frame 110; Figure 6 yes Figure 3 A front view of the liquid filling device 100 after removing the fixing frame 110; Figure 7 yes Figure 3 Side view of the liquid filling device 100 after removing the fixing frame 110; Figure 8 yes Figure 1 A schematic diagram of the assembled packaging bottle conveying device 200 and packaging bottle docking assembly 140.

[0055] Reference Figures 1 to 8 As shown in the figure, this application provides a bottled liquid filling system, including a liquid filling device 100 and a packaging bottle conveying device 200. The liquid filling device 100 includes a fixed frame 110, a liquid hopper 120, a liquid suction and discharge assembly 130, and a packaging bottle docking assembly 140. The fixed frame 110 is mounted on the ground, providing a foundation for the installation and support of each component. The liquid hopper 120 is fixedly mounted above the fixed frame 110 and is used to hold the liquid to be filled. The liquid suction and discharge assembly 130 is mounted on the fixed frame 110 and selectively connected to the liquid hopper 120 via a pipeline. Since the liquid hopper 120 is also located above the fixed frame 110, the liquid easily enters the liquid suction and discharge assembly 130 under the influence of gravity. The packaging bottle docking assembly 140 is mounted on the fixed frame 110. The packaging bottle docking assembly 140 is used to dock with the packaging bottle, and it is selectively connected to the liquid suction and discharge assembly 130 through a pipeline. The liquid suction and discharge assembly 130 is used to transfer a certain amount of liquid to be filled into the packaging bottle through the packaging bottle docking assembly 140.

[0056] When filling the packaging bottle, the liquid suction and discharge assembly 130 is first connected to the liquid hopper 120. A fixed amount of liquid to be filled enters the liquid suction and discharge assembly 130 from the liquid hopper 120. Then, the packaging bottle docking assembly 140 is connected to the liquid suction and discharge assembly 130, and the passage between the liquid suction and discharge assembly 130 and the liquid hopper 120 is closed. The liquid suction and discharge assembly 130 fills the packaging bottle with the liquid to be filled inside through the pipeline and the packaging bottle docking assembly 140.

[0057] For example, the liquid silo 120 is a box structure used to store liquid to be filled, which is the prior art.

[0058] Reference Figures 3 to 7As shown, specifically, the liquid suction and discharge assembly 130 includes a piston metering suction and discharge assembly 131, a piston drive assembly 132, and a three-way angle seat valve 133. The piston metering suction and discharge assembly 131 is fixedly mounted on the fixed frame 110, and its upper end is selectively connected to the liquid hopper 120 and the packaging bottle docking assembly 140 via the three-way angle seat valve 133. For example, one port of the three-way angle seat valve 133 is connected to the piston metering suction and discharge assembly, while the other two ports are connected to the liquid hopper 120 and the packaging bottle docking assembly 140 respectively via pipelines. Furthermore, the three-way angle seat valve 133 is also connected to a high-pressure gas device to control the on / off state of each pipeline via high-pressure gas. It should be noted that using high-pressure gas to control the on / off state of the three-way angle valve pipeline is existing technology and will not be elaborated upon here. A piston drive assembly 132 is mounted on a fixed frame 110 and is connected to a piston metering suction and discharge assembly 131. The piston drive assembly 132 is used to allow liquid in the liquid hopper 120 to enter or exit the piston metering suction and discharge assembly 131. For example, the piston metering suction and discharge assembly 131 is positioned on the fixed frame 110, with the piston drive assembly 132 positioned below it, driving the piston metering suction and discharge assembly 131 to perform the suction and discharge action of the liquid.

[0059] For example, the piston metering assembly 131 includes a metering cylinder 1311 and a piston part 1312. The metering cylinder 1311 is vertically fixed on the fixing frame 110, and the piston part 1312 is fitted inside the metering cylinder 1311. The upper end of the metering cylinder 1311 is connected to the liquid hopper 120 and the packaging bottle docking assembly 140 respectively through a three-way angle seat valve 133. The piston part 1312 is connected to the piston drive assembly 132. When the piston drive assembly 132 drives the piston part 1312 to move downward, it controls the three-way angle seat valve 133 to connect the metering cylinder 1311 to the liquid hopper 120 and close the passage between the metering cylinder 1311 and the packaging bottle docking assembly 140, so that the liquid to be filled in the liquid hopper 120 is drawn into the metering cylinder 1311. Next, the three-way angle seat valve 133 is controlled to close the passage between the metering cylinder 1311 and the liquid hopper 120, and to connect the metering cylinder 1311 and the packaging bottle docking assembly 140. The piston drive assembly 132 drives the piston part 1312 to move upward, thereby discharging the liquid in the metering cylinder 1311 into the packaging bottle through the packaging bottle docking assembly 140.

[0060] Continue to refer to Figure 5As shown, the piston drive assembly 132 includes a first drive motor 1321, a lifting transmission assembly 1322, and a packaging bottle conveying assembly 1323. The first drive motor 1321 is mounted on the fixed frame 110; the packaging bottle conveying assembly 1323 is vertically mounted on the fixed frame 110 and connected to the piston portion 1312; one end of the lifting transmission assembly 1322 is connected to the output end of the first drive motor 1321, and the other end is connected to the packaging bottle conveying assembly 1323. The first drive motor 1321 drives the packaging bottle conveying assembly 1323 to move via the lifting transmission assembly 1322, thereby driving the piston portion 1312 to rise and fall. For example, the lifting transmission assembly 1322 can be a chain drive assembly 1424b. The first drive motor 1321 can be a servo motor or a DC drive motor with a reducer; no specific limitation is made here.

[0061] like Figures 3 to 7 As shown, in some examples, multiple piston metering suction and discharge assemblies 131 and three-way angle seat valves 133 are provided, with each three-way angle seat valve 133 mounted on a corresponding piston metering suction and discharge assembly 131. All piston metering suction and discharge assemblies 131 are arranged vertically and at intervals on the fixed frame 110, and each piston metering suction and discharge assembly 131 is connected to the liquid hopper 120 and the corresponding packaging bottle docking assembly 140 through the corresponding three-way angle seat valve 133. The piston parts 1312 of all piston metering suction and discharge assemblies 131 are fixedly connected together by a connecting plate. The packaging bottle conveying assembly 1323 is connected to the connecting plate. The first drive motor 1321 drives the connecting plate to rise and fall through the lifting transmission assembly 1322 and the packaging bottle conveying assembly 1323. The connecting plate drives all piston parts 1312 to rise and fall simultaneously, so as to fill multiple packaging bottles with liquid at the same time.

[0062] Figure 8 yes Figure 1 A schematic diagram of the assembled packaging bottle conveying device 200 and packaging bottle docking assembly 140; Figure 9 yes Figure 3 First schematic diagram of the packaging bottle docking assembly 140 in the middle; Figure 10 yes Figure 9 A second schematic diagram of the packaging bottle docking assembly 140. (Refer to...) Figures 8 to 10 As shown, in some examples, the bottle docking assembly 140 includes a filling head assembly 141 and a fixing assembly 142. The fixing assembly 142 is disposed on the fixing frame 110, and the filling head assembly 141 is fixedly disposed on the fixing assembly 142, and the filling head assembly 141 communicates with the liquid suction and discharge assembly 130. Exemplarily, the fixing assembly 142 may be a frame structure formed by connecting profiles. The filling head assembly 141 includes a filling tube 1411 and a pneumatic angle seat valve 1412.

[0063] For example, the filling tube 1411 can be a straight tube with a diameter smaller than the bottle opening size. The filling tube 1411 is vertically and fixedly mounted on the fixing assembly 142. A pneumatic angle seat valve 1412 is located at the upper end of the filling tube 1411. The pneumatic angle seat valve 1412 is connected to the liquid suction and discharge assembly 130 through a pipeline. The pneumatic angle seat valve 1412 can be used to open and close the filling tube 1411 to prevent liquid in the pipeline from flowing into the bottle and causing the liquid in the bottle to overflow due to excessive amount.

[0064] Continue to refer to Figures 8 to 10 As shown, in some examples, the bottle docking assembly 140 is height-adjustable to allow it to extend into the bottle for liquid filling, preventing liquid from flowing onto the bottle body. Exemplarily, in these examples, the fixing assembly 142 includes a fixing frame 1421, a mounting base 1422, a guide assembly 1423, and a filling lifting assembly 1424. The fixing frame 1421 is fixedly mounted on the fixing frame body 110, the guide assembly 1423 is vertically disposed on the fixing frame 1421, the mounting base 1422 is fitted onto the guide assembly 1423, the filling head assembly 141 is fixedly disposed on the mounting base 1422, and the filling lifting assembly 1424 is disposed on the fixing frame body 110 and connected to the mounting base 1422. The filling lifting assembly 1424 drives the mounting base 1422 to move up and down along the guide assembly 1423.

[0065] For example, the filling lifting assembly 1424 can be a linear drive assembly such as a cylinder or hydraulic cylinder, or it can be a motor drive assembly. Specifically, such as Figure 9 and Figure 10 As shown, in some examples, the filling lifting assembly 1424 includes a drive rod 1424a, a chain drive assembly 1424b, and a second drive motor 1424c. The drive rod 1424a is vertically disposed within the fixed frame 110, with its lower end connected to the drive chain of the chain drive assembly 1424b and its upper end connected to the mounting base 1422. The second drive motor 1424c is fixedly disposed on the fixed frame 110. The second drive motor 1424c drives the drive rod 1424a to rise and fall through the chain drive assembly 1424b, thereby driving the mounting base 1422 to rise and fall, thus controlling the rise and fall of the filling head assembly 141, enabling it to extend into or be removed from the packaging bottle.

[0066] Figure 11 yes Figure 1 A first schematic diagram of the packaging bottle conveying device 200 in the middle; Figure 12 yes Figure 11 A second schematic diagram of the packaging bottle conveying device 200.

[0067] Reference Figure 11 and Figure 12As shown, in some examples, the bottle conveying device 200 includes a conveying frame 210, a flexible conveying assembly 220, a conveying drive assembly (not shown), and a limiting assembly 230. The conveying frame 210 can be mounted on the ground to provide fixed support for the various components. The flexible conveying assembly 220 is mounted on the conveying frame 210 along its length. The conveying drive assembly is mounted on the conveying frame 210 and connected to the flexible conveying assembly 220. The conveying drive assembly drives the flexible conveying assembly 220 to rotate, thereby conveying the bottle to a position below the liquid filling device 100. After the bottle is filled with liquid, the flexible conveying assembly 220 can convey the filled bottle to a designated location. Additionally, limiting components 230 are disposed on the conveyor frame 210 and extend along the length of the conveyor frame 210. Two limiting components 230 are provided, located on either side of the flexible conveyor component 220, to confine the packaging bottle to the flexible conveyor component 220 and prevent it from falling off. It should be noted that the length of the conveyor frame 210 can be referenced... Figure 11 As shown in the y-direction, the length direction of the conveyor frame 210 can be referenced. Figure 11 The x-direction is shown in the figure.

[0068] The height of the two limiting components 230 can be adaptively adjusted according to the height of the packaging bottle, as long as it can block the packaging bottle and ensure that it will not fall off the flexible conveying component 220.

[0069] Continue to refer to Figure 11 and Figure 12 As shown, the bottle conveying device 200 also includes two blocking components 240. These two blocking components 240 are disposed on the conveying frame 210 and located at opposite ends of the conveying frame 210 along its length. The blocking components 240 are used to selectively block the movement of multiple bottles. For example, when filling empty bottles with liquid, along the conveying direction of the flexible conveying component 220, the blocking component 240 at the front end extends and blocks the flexible conveying component 220 in that direction. Multiple bottles moving along the flexible conveying component 220 are sequentially blocked by the blocking components 240 and placed in the filling area below the liquid filling device 100, waiting to be filled. After a set time, the blocking component 240 at the rear end extends and blocks the flexible conveying component 220 in that direction, preventing empty bottles from entering the filling area. After filling is completed, the two blocking components 240 retract in sequence. The bottle containing the liquid and the empty bottle continue to move forward with the flexible conveyor. The bottle containing the liquid is moved to the designated position, while the empty bottle enters the filling area to wait for filling. This cycle repeats continuously.

[0070] Specifically, in some examples, the blocking assembly 240 includes a linear drive component 241 and a blocking member 242. The linear drive component 241 is horizontally fixed to the upper surface of the conveyor frame 210. The blocking member 242 is movably connected to the conveyor frame 210 and connected to the linear drive component 241. The linear drive component 241 selectively drives the blocking member 242 to move along the width direction of the conveyor frame 210. Exemplarily, the linear drive component 241 may be a cylinder, hydraulic cylinder, electric push rod, or lead screw nut linear drive assembly, and the blocking member 242 may be a blocking rod, blocking plate, or other blocking component. Figure 12 As shown, in this application, the linear drive component 241 is configured as a cylinder, the blocking component 242 is configured as a blocking rod, the blocking component 242 is fitted in the mounting base 1422 located on the conveyor frame 210, the cylinder is also installed in the mounting base 1422, and the movable end of the cylinder is fixedly connected to the blocking component 242. The cylinder drives the blocking component 242 to extend and retract along the width direction of the conveyor frame 210.

[0071] Continue to refer to Figure 11 and Figure 12 As shown, the packaging bottle conveying device 200 also includes two counting components 250, which are respectively disposed at both ends of the conveying frame 210 along the length direction to detect the packaging bottles, thereby facilitating the control of the extension and retraction of the two blocking components 240 according to the number of packaging bottles.

[0072] Specifically, the counting component 250 includes a mounting frame 251, a mirror plate 252, and a mirror sensor 253. The mounting frame 251 is fixedly mounted on the conveyor frame 210 and spans across the flexible conveyor component 220. The mirror plate 252 and the mirror sensor 253 are fixedly mounted on the mounting frame 251, and are located on opposite sides of the flexible conveyor component 220. The height of the mirror plate 252 and the mirror sensor 253 must be lower than the height of the packaging bottle. When the packaging bottle passes between them, it can block the mirror sensor 253, thus allowing the bottle to be detected.

[0073] To ensure accurate positioning of the packaging bottles in the filling area and to ensure that the liquid filling device 100 accurately fills the liquid into the packaging bottles, the packaging bottle conveying device 200 also includes a clamping assembly 260. Exemplarily, the clamping assembly 260 includes a clamping frame 261, a clamping drive assembly 262, a first clamping part 263, and a second clamping part 264. The clamping frame 261 is fixedly mounted on the conveying frame 210 and is at a certain height above the conveying frame 210. The first clamping part 263 is connected to the clamping frame 261, the clamping drive assembly 262 is mounted on the clamping frame 261 and connected to the first clamping part 263, and the second clamping part 264 is fixedly mounted on the fixed frame 110 and is positioned opposite to the first clamping part 263. After the packaging bottles enter the packaging area in sequence, the clamping drive assembly 262 drives the first clamping part 263 to extend and, together with the second clamping part 264, clamps the packaging bottles to achieve positioning of the packaging bottles.

[0074] For example, the first clamping part 263 is provided with an opening that matches the packaging bottle, and the packaging bottle can be confined in the opening. For example, the shape of the opening can be a triangle that increases in size from the outside to the inside.

[0075] For example, the first clamping part 263 includes a connecting plate and a plurality of clamping blocks, which are sequentially spaced on the connecting plate, and the connecting plate is fixedly connected to the clamping drive assembly 262. The second clamping part 264 can be a strip-shaped structure or other shapes, as long as it can cooperate with the first clamping part 263 for clamping. In addition, for example, the clamping drive assembly 262 can be a linear drive assembly such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder, all of which are prior art and will not be described in detail here.

[0076] Continue to refer to Figure 12As shown, the clamping assembly 260 further includes a lifting plate and a lifting drive assembly 265 (filling lifting assembly 1424). The lifting plate is slidably connected to the clamping frame 261. A first clamping part 263 is movably disposed on the lifting plate. The clamping drive assembly 262 is disposed on the lifting plate and connected to the first clamping part 263. The clamping drive assembly 262 is used to drive the first clamping part 263 to selectively extend and retract along the width direction of the conveying frame 210. The lifting drive assembly 265 (filling lifting assembly 1424) is disposed on the clamping frame 261 and connected to the lifting plate. The lifting drive assembly 265 (filling lifting assembly 1424) is used to drive the lifting plate to move up and down. Specifically, the clamping frame 261 is provided with a guide rod, and the lifting plate is fitted onto the guide rod. The lifting drive assembly 265 (filling lifting assembly 1424) is configured as a screw drive assembly. The screw drive assembly is vertically installed inside the clamping frame 261. When the screw drive assembly is activated, it can drive the lifting plate to rise and fall, thereby adjusting the height of the first clamping part 263 to accommodate packaging bottles of different heights.

[0077] Reference Figure 7 As shown, in some embodiments, the second clamping part 264 is fitted onto the fixing component 142 of the packaging bottle docking assembly 140. A clamping part lifting drive assembly is provided at the upper end of the fixing component 142. The clamping part lifting drive assembly is used to drive the second clamping part 264 to rise and fall within the fixing component 142 to adjust to an appropriate height, so as to clamp and fix the packaging bottle together with the first clamping part 263. For example, the clamping part lifting drive assembly can be a lead screw and nut drive assembly.

[0078] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application. It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application.
