Description

Technical Field

[0001] This utility model relates to the field of mineral water bottling technology, specifically to a mineral water bottling device. Background Technology

[0002] Mineral water bottling is an essential part of the mineral water production process. It typically involves filling machines equipped with multiple filling heads to fill bottles in batches on a conveyor line. While the structure of most mineral water filling machines on the market meets basic filling requirements, their effectiveness in securing the bottles at the bottle neck during the filling process is often less than ideal. Although they ensure the filling head can reach the bottle, some smaller, standard-capacity bottles are prone to some degree of shaking during the initial filling of empty bottles. This shaking usually occurs as the mineral water content in the bottle increases. As the quantity increases and gradually stabilizes, this phenomenon has two main effects. First, the bottle body is prone to bumping against the filling head during shaking, potentially causing deformation or tilting of the filling head, affecting its light efficiency and filling efficiency. Second, the shaking of the bottle body also causes fluctuations in the amount of mineral water inside during the filling process. This not only makes it easy for the mineral water reaching the bottle mouth to splash and leak, but also negatively impacts the process of detecting the liquid level of the mineral water inside the bottle after filling, increasing detection errors and affecting detection stability. Utility Model Content

[0003] The purpose of this utility model is to provide a mineral water filling device that can ensure the stability of the bottle body and the corresponding bottle mouth during the filling process, further improve the filling stability and filling efficiency of the filling head, and also effectively improve the detection effect and detection stability during the liquid level detection process.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A mineral water filling device includes a conveying assembly for conveying bottles and a filling assembly for filling the bottles with mineral water, forming a filling machine body. The filling assembly includes a fixed frame and a water storage tank mounted on it, as well as multiple filling heads that are fixed and mounted on the fixed frame and connected to the bottom of the water storage tank through multiple sets of pipes. The mounting frame is driven to slide up and down by a first cylinder mounted on the fixed frame. A second mounting frame is also connected to the fixed frame below the mounting frame. The second mounting frame includes baffles mounted on both sides below the filling heads and a clamping plate mounted on one side of the baffles that is driven to slide left and right by a second cylinder mounted on the second mounting frame. Multiple liquid level sensors are mounted below the baffles.

[0006] Preferably, the filling head includes a first rod for mounting and fixing on a mounting frame and a second rod connected to the first rod by an adapter spring sleeved on the outside of the first rod and sliding up and down along the outside of the first rod. The first rod has an outlet at its bottom, and the pipeline is connected to the second rod by an inlet on the second rod. The bottom of the second rod also has an outer edge.

[0007] Preferably, the filling head is slidably mounted on the mounting frame via a groove provided at a corresponding position on the mounting frame, and is detachably mounted on the mounting frame via a locking member rotatably provided above the first rod.

[0008] Preferably, a pipe valve is installed at the connection point between the pipeline and the bottom of the water storage tank.

[0009] Preferably, the liquid level sensor is slidably mounted on the baffle, the baffle has a through groove and a connecting plate that slides up and down through an adjusting member that is rotatably mounted on the baffle, and the liquid level sensor is mounted on the connecting plate.

[0010] Preferably, the second mounting bracket further includes a water storage tank located below multiple filling heads, connected to the second cylinder, and configured to drive and hold the plates to slide synchronously.

[0011] Preferably, the filling machine body further includes a capping assembly mounted on the conveying assembly. The capping assembly includes a second fixing frame and a transfer chuck mounted on it above the conveying assembly and driven to rotate by a driving component. A capping device and a capping device are mounted above the transfer chuck via a first connecting seat and a second connecting seat, respectively. The transfer chuck includes a first chuck for fixing the bottle mouth and multiple sets of second chucks for fixing the bottle body, formed by several slots arranged vertically around the rotating shaft and of different sizes. The capping device includes a pressing seat that slides vertically and vertically via a third cylinder mounted on the first connecting seat and is used for pressing the bottle cap, and an adapter seat located below the pressing seat for locking the bottle cap and having a through hole. The capping device includes a third connecting seat that slides vertically and vertically on the second connecting seat via a fourth cylinder and a capping head that rotates on the third connecting seat via a second driving component. A matching second compression spring is sleeved at the connection position between the second driving component and the capping head.

[0012] Compared with the prior art, this utility model has the following advantages and effects:

[0013] This utility model relates to a mineral water filling device. Compared to conventional mineral water filling machine bodies, the overall structure of the filling component on the conveying assembly can be combined with the structure of the clamping plate on the second mounting frame. This ensures the stability of the bottle body and corresponding bottle mouth during the filling process, effectively avoiding large shaking amplitude of the filling head on the bottle body in the early stage of filling, and reducing the likelihood of the filling head hitting the bottle. It also ensures the accuracy of the position of the filling head and the corresponding bottle mouth during movement, preventing bottle position deviation that could lead to deformation, skewness, or even damage to the filling head, thus avoiding adverse effects on filling stability and efficiency. Furthermore, it effectively reduces the fluctuation amplitude of mineral water inside the bottle during the filling process, reducing splashing and leakage. It also further improves the accuracy and stability of liquid level detection by the liquid level sensor, reducing detection errors. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0018] See Figure 1-4This embodiment relates to a mineral water filling device, including a conveying assembly 1 for conveying a bottle 100 and a filling assembly 2 for filling mineral water into the bottle 100, forming a filling machine body. The filling assembly 2 includes a fixed frame 21 and a water storage tank 22 disposed thereon, and multiple filling heads 24 that are fixed and installed on the fixed frame 21 by a mounting frame 23 corresponding to the conveying assembly 1 and connected to the bottom of the water storage tank 22 by multiple sets of pipes 20. The mounting frame 23 is driven to slide up and down by a first cylinder 25 disposed on the fixed frame 21. A second mounting frame 26 is also connected to the fixed frame 21 below the mounting frame 23. The second mounting frame 26 includes baffles 261 disposed on both sides below the filling heads 24 and a clamping plate 262 disposed on one side of the baffles 261 and driven to slide left and right by a second cylinder 27 disposed on the second mounting frame 26. Multiple liquid level sensors 263 are installed below the baffles 261.

[0019] Specifically in this embodiment, see Figure 1The overall structure of this mineral water bottling device, including its conveying component 1 and filling component 2, is shown. In use, the conveying component 1 employs a conventional chain conveyor structure, coupled with a chain conveyor 11 and a first drive motor 12 for rotating the chain conveyor 11, to convey a batch of bottles 100. The batch of bottles 100 conveyed by the conveying component 1 can then be filled with mineral water via the filling component 2. Specifically, when a corresponding number of bottles 100 correspond to the positions of multiple filling heads 24, the second cylinder 27 on the corresponding side of the second mounting frame 26 begins operation and drives the clamping plate 262 along the direction of the baffle 13 on the other side. The movement of the second mounting frame 26, with its corresponding height settings for the side baffles 13 and clamping plates 262, allows for the simultaneous clamping of corresponding bottle openings on the chain conveyor 11 by coordinating the clamping plates 262 with the slots 2621 on their corresponding surfaces and the other side baffle 13. Furthermore, to ensure the stability of the bottle openings during clamping, the distance between the side plates on both sides of the chain conveyor 11 can be appropriately adjusted according to the required bottle size, without affecting the normal conveying process of the bottle on the conveying assembly 1. This adjustment is coordinated with the distance between the corresponding baffles 261 and clamping plates 262 on the second mounting frame 26. The height should be set so that the gap between the bottle mouth and the corresponding side baffle 13 plate is further reduced during the conveying process of the bottle body 100. This allows the bottle body 100 on the chain conveyor 11 to remain stationary as much as possible during the clamping and fixing process of the clamping plate 262. Then, the corresponding bottle body 100 is clamped and fixed by the second mounting frame 26. The first cylinder 25 on the fixing frame 21 can push the mounting frame 23 and the multiple sets of filling heads 24 installed on it to move downward along the lower conveying assembly 1 corresponding to multiple bottles 100 on the chain conveyor 11. This causes the filling head 24 to extend into the corresponding bottle mouth of the bottle body 100 to an appropriate length, and the filling process of mineral water into the bottle body 100 can then be carried out. Specifically, the fixing... The water storage tank 22 installed on the frame 21 can be filled and stored with a certain amount of mineral water. The mineral water in the water storage tank 22 can be continuously supplied to the filling heads 24 and continuously dispensed into the bottle body 100 through multiple sets of pipes 20 connected to the bottom of the filling heads 24. To ensure the stability of the water supply during the up-and-down movement of the filling heads 24, the pipes 20 can be made of flexible materials. This ensures the stability of the connection between the water storage tank 22 and the filling heads 24 without affecting the up-and-down movement of the filling heads 24 during the filling process. As the filling process continues, when the mineral water content in the bottle body 100 reaches a certain level, it can be referenced... Figure 4As shown, multiple sets of liquid level sensors 263 installed on one side of the baffle 261 of the second mounting frame 26 can detect the specific liquid level of mineral water inside the bottle 100 at the corresponding position. This allows them to work with the corresponding control elements on the filling assembly 2 connected to the liquid level sensors 263 to control the flow of mineral water from the filling head 24 and stop the flow. Finally, after all the bottles 100 at the corresponding positions of the conveying assembly 1 and the filling assembly 2 have been filled, the second cylinder 27 on the second mounting frame 26... The first cylinder 25 on the fixed frame 21 drives the clamping plate 262 and the second mounting frame 26 back to their initial positions in sequence. After filling, the corresponding number of bottles 100 on the chain conveyor 11 can move away from the filling component 2 on the chain conveyor 11 under the drive of the first drive motor 12 and can be capped, packaged and other subsequent operations. At the same time, the batch of bottles 100 that have not been filled by the filling component 2 are placed under the filling head 24 to repeat the above process of continuous filling. Compared to conventional mineral water filling machines, this mineral water filling device features a unique overall structure for the filling component 2 on the conveying assembly 1. This structure, combined with the added clamping plate 262 on the second mounting frame 26, ensures the stability of the bottle body and corresponding opening during the filling process. This effectively prevents significant shaking of the bottle body 100 caused by the filling head 24 during the initial filling stage, reducing the likelihood of collisions with the filling head 24. Furthermore, it ensures the accurate positioning of the filling head 24 relative to the bottle opening during movement, preventing deformation, skewness, or even damage to the filling head 24 due to bottle body misalignment, which would negatively impact filling stability and efficiency. Additionally, it effectively reduces fluctuations in the mineral water level inside the bottle body 100 during filling, minimizing splashing and leakage. Finally, it further improves the accuracy and stability of the liquid level sensor 263 in detecting the liquid level, reducing detection errors.

[0020] The filling head 24 includes a first rod 241 for mounting and fixing on the mounting bracket 23, and a second rod 242 connected to the first rod 241 by an adapter spring 243 sleeved on the outside of the first rod 241 and sliding up and down along the outside of the first rod 241. An outlet 2411 is provided at the bottom of the first rod 241. The pipeline 20 is connected to the second rod 242 through an inlet 2421 provided on the second rod 242, and the bottom of the second rod 242 is also provided with an outer edge 2422. (See also...) Figure 2 and Figure 3The filling head 24 shown in the diagram has a specific structural configuration. During the filling process, multiple sets of filling heads 24 on the mounting frame 23 move downwards under the push of the first cylinder 25 on the fixed frame 21. During the movement, the bottom of the first rod 241 and the second rod 242 of the filling head 24 can appropriately extend into the corresponding bottle opening of the bottle body 100 by a certain length. With the push of the first cylinder 25, the outer edge 2422 structure at the bottom of the second rod 242 can contact and abut against the top of the corresponding bottle opening of the bottle body 100. Furthermore, with the continuous push of the first cylinder 25, the first rod 241 inside the second rod 242 can move along the bottle opening under the action of the compression spring 243. The filling head 24 continues to move downwards into the bottle 100 to a suitable length, allowing the mineral water that enters the second rod 242 through the water tank 22 connected to the water inlet 2421 on the second rod 242 via the pipe 20 to be discharged through the corresponding rod with the corresponding water outlet 2411 below it as the first rod 241 moves. This enables a continuous filling process of mineral water from the second rod 242 into the bottle 100 via the water outlet 2411 below the first rod 241. After filling is completed, when the filling head 24 moves upwards under the action of the first cylinder 25, the outer periphery of the first rod 241 slides. The second rod 242, under the action of the compression spring 243, can block the corresponding rod with the water outlet 2411 below the first rod 241 and return to its initial position to stop water discharge. The filling head 24 with this structure can be configured to cooperate with the first rod 241 and the second rod 242, which is connected to its outer side via the compression spring 243 and slides vertically, to meet the water discharge requirements. This further improves the structural strength of the filling head 24 and provides some protection for the first rod 241, reducing deformation and tilting of the first rod 241, improving the filling effect and stability of the filling head 24, and effectively preventing the first rod from... The body 241 is exposed to the external environment for a long time during the filling process, which may cause unnecessary pollution to the mineral water in the bottle 100, thus improving the filling quality of the mineral water. In addition, the addition of the structure of the bottom of the second rod 242 adapting to the outer edge 2422 can further improve the connection effect with the corresponding bottle mouth of the bottle 100, effectively avoiding the phenomenon of mineral water splashing and leakage during the filling process. At the same time, it can also further improve the fixed stability of the bottle 100, reduce the vibration amplitude of the filling head 24 and the bottle 100 during the filling process, and reduce the unnecessary impact on the filling of the filling head 24, thereby improving the filling efficiency and filling stability of the filling component 2.

[0021] like Figure 3As shown, the filling head 24 is slidably mounted on the mounting frame 23 via a groove 231 provided at a corresponding position on the mounting frame 23, and is detachably mounted on the mounting frame 23 via a locking member 2412 rotatably mounted above the first rod 241. The filling head 24, mounted on the mounting frame 23 in this manner, can be detachably connected and fixed in the corresponding number and position of the groove 231 via the locking member 2412 rotatably mounted on it according to the actual filling requirements and the specific specifications of the bottle 100. The locking member 2412 can adopt a conventional threaded connection structure and be rotatably connected with the threaded structure provided at the corresponding position of the first rod 241. Specifically, the distance between the filling heads 24 can be adaptively adjusted and locked according to the corresponding specifications of the bottle 100 by sliding along the groove 231 on the mounting frame 23, which facilitates the installation, disassembly, cleaning, and replacement of the filling head 24, meets different usage requirements, and improves the flexibility and convenience of use.

[0022] Each of the pipes 20 and the bottom of the water storage tank 22 is equipped with a pipe valve 220, which allows for the connection between the pipe 20 and the bottom of the water storage tank 22. Figure 2 As can be seen, the pipe valve 220 adopts the control valve commonly used on conventional pipelines 20 with an adapted structure. By rotating the adjustment knob on it, the opening and closing process of a corresponding number of pipelines 20 can be controlled according to different filling requirements. It can be conveniently operated and flexibly adjusted according to different filling requirements, thus improving applicability and practicality.

[0023] like Figure 4 As shown, the liquid level sensor 263 is slidably mounted on the baffle 261. The baffle 261 has a through groove 2611, and a connecting plate 2612 is disposed within the through groove 2611, sliding up and down via an adjusting member 2613 rotatably mounted on the baffle 261. The liquid level sensor 263 is mounted on the connecting plate 2612. In this manner, the liquid level sensor 263 mounted on the baffle 261 can, during actual use, slide up and down on the connecting plate 2612 in the through groove 2611 by rotating the adjusting member 2613 according to filling requirements. The process of adjusting the position of the liquid level sensor 263 on the baffle 261 at an appropriate height involves the adjustment component 2613 being set with a conventional bolt connection structure and rotatably mounted in the threaded holes provided at corresponding positions on the connecting plate 2612 and the baffle 261, thereby realizing the sliding process of the connecting plate 2612. This allows for flexible adjustment of the liquid level sensor 263 at the corresponding height according to different filling requirements, improving operational convenience and applicability. Furthermore, the through groove 2611 opened in the baffle 261 also facilitates the wiring connection and arrangement of the liquid level sensor 263.

[0024] The second mounting bracket 26 also includes a water storage tank located below the multiple filling heads 24, connected to the second cylinder 27, and synchronously sliding with the clamping plate 262. Figure 1 or Figure 2 The structure and installation position of the water storage tank shown are such that the water storage tank can move up and down in conjunction with the filling head 24 during the filling process. Driven by the second cylinder 27, it moves synchronously with the clamping plate 262. At the same time, the installation position of the water storage tank does not interfere with the installation position of the connecting plate 2612 on the corresponding through groove 2611 of the baffle 261, thus ensuring the normal movement of the water storage tank on the second mounting frame 26. When the filling head 24 finishes filling, the water storage tank, which is then placed below the filling head 24 by the action of the second cylinder 27, can collect water droplets that drip inside the filling head 24 when it is stationary. This effectively prevents unnecessary water droplets from dripping into the bottle 100, thus reducing filling errors and the probability of unnecessary contamination or even damage to the conveying component 1 below. It also allows for timely inspection and maintenance of the filling head 24 based on the water accumulation in the water storage tank, improving the working stability of the filling head 24.

[0025] See Figure 1The filling machine body also includes a capping assembly 3 mounted on the conveying assembly 1. The capping assembly 3 includes a second fixing frame 30 and a transfer chuck 31 mounted on the second fixing frame 30 above the conveying assembly 1 and driven to rotate by a driving component 300. A capping device 32 and a capping device 33 are mounted on the transfer chuck 31 via a first connecting seat 301 and a second connecting seat 302, respectively. The transfer chuck 31 includes a first chuck 311 for fixing the bottle neck and multiple sets of second chucks 312 for fixing the bottle body, formed by several slots 310 arranged vertically around the rotating shaft and of different sizes. The capping device 32 includes a third cylinder 321 mounted on the first connecting seat 301 that drives it to slide up and down. The capping device 33 includes a pressure seat 322 for cap pressing and an adapter seat 323 located below the pressure seat 322 for cap clamping and with a through hole. The capping device 33 includes a third connecting seat 303 that is driven up and down on the second connecting seat 302 by a fourth cylinder and a capping head 332 that is driven to rotate on the third connecting seat 303 by a second driving component 331. A matching second compression spring 333 is sleeved at the connection position between the second driving component 331 and the capping head 332. Under the continuous conveying action of the conveying component 1, the batch of bottles 100 that have been filled by the filling component 2 can be immediately capped by the capping component 3. Specifically, the corresponding bottles 100 located on the chain conveyor 11 can be sealed by a transfer chuck. The matching slots 310 on the first chuck 311 and the second chuck 312 of the transfer chuck 31 are respectively matched and locked to the corresponding bottle mouth and bottle body of the bottle 100. They can be rotated under the drive of the driving component 300 on the second fixed frame 30, thereby driving the multiple bottles 100 locked on the slots 310 of the transfer chuck 31 to perform the transfer process. The corresponding bottles 100 locked on the transfer chuck 31 can be capped and tightened on the bottle mouth by the capping device 32 and the capping device 33, respectively. Specifically, the bottle cap can be placed on the card seat 323 for matching and locking. At the same time, the third cylinder 321 provided on the first connecting seat 301 can push the pressure seat 322 to move along the lower card seat 323, thereby driving the card seat. The bottle cap, secured on 323, moves downwards through the through-hole in the chuck 323 to the corresponding bottle mouth on the transfer chuck 31 for initial capping. Then, the rotation of the transfer chuck 31 moves the corresponding bottle 100 below the capper 33. A fourth cylinder on the second connecting seat 302 operates, pushing the third connecting seat 303 downwards. Specifically, the connection structure between the second connecting seat 302 and the third connecting seat 303 can be a conventional slide structure. During sliding, the third connecting seat 303 can slide up and down on the second connecting seat 302 via multiple sets of sliders that cooperate with the corresponding sliding rails installed on the second connecting seat 302.The capping head 332, connected to the second driving component 331 on the third connecting seat 303, can contact and engage with the corresponding cap on the bottle neck of the bottle body 100. Simultaneously, the capping head 332 rotates under the drive of the second driving component 331, and, buffered by the second compression spring 333 at its connection point, tightens the cap on the bottle neck of the bottle body 100. After being capped by the capper 33 on the transfer chuck 31, the corresponding bottle body 100 can be transported and packaged along the chain conveyor 11 in the corresponding conveying direction of the conveying assembly 1 as the transfer chuck 31 rotates. The addition of the capping assembly 3 further enhances the functionality and efficiency of this mineral water bottling device. The overall structure of the transfer chuck 31, capper 32, and capper 33 is relatively simple, facilitating operation and adjustment, as well as structural additions and routine inspections and maintenance of the components, meeting diverse usage needs.

[0026] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
