Description

Technical Field

[0001] This utility model relates to the field of liquid filling technology, specifically to an automatic filling machine for a highly stable water-based cleaning agent. Background Technology

[0002] In industrial production, water-based cleaning agents are widely used in industries such as hardware, electronics, and machinery due to their advantages of being environmentally friendly and having good cleaning effects. The filling process, as a crucial link in the production flow, has increasingly urgent requirements for automation, precision, and equipment stability. Traditional filling machines have many shortcomings, such as simple structural design, susceptibility to mechanical vibration and material impact during filling leading to large filling volume errors, affecting product quality consistency; poor coordination between conveying and filling processes resulting in low production efficiency and difficulty in adapting to large-scale continuous production; and poor compatibility of some equipment with different container sizes, requiring time-consuming adjustments and increasing production and time costs for enterprises.

[0003] Traditional liquid filling mainly relies on manual labor or semi-automatic equipment. It uses basic physical principles such as gravity, pressure, and vacuum to fill liquid materials into containers. Filling requires frequent starting and stopping of equipment and manual alignment of the bottles, which is not only labor-intensive but also prone to errors in filling volume due to inconsistent operating rhythms, making it difficult to meet the needs of large-scale continuous production. At the same time, manual intervention increases the chance of cleaning agents coming into contact with the external environment, potentially affecting product stability. However, this filling method has limitations such as low efficiency, poor accuracy, high hygiene risks, and high labor intensity, making it difficult to meet the demands of modern large-scale, high-precision, and high-hygiene production standards.

[0004] In addition, the liquid outlet structure of existing filling equipment is mostly a fixed conduit. After filling, the residual cleaning agent on the inner wall of the conduit is prone to dripping due to gravity, causing contamination of the outer wall of the packaging bottle, a dirty production environment, and even waste of cleaning agent. Although some equipment attempts to control the liquid outlet by quickly closing the valve, it still cannot completely solve the problem of residual liquid dripping from the conduit.

[0005] Therefore, there is an urgent need for a highly automated, stable water-based cleaning agent automatic filling machine that can effectively prevent leakage after filling, in order to solve the problems of low efficiency, large error, high hygiene risk and high labor intensity of traditional filling methods, and meet the needs of large-scale and high-standard production. Utility Model Content

The coordinated work of each part ensures the orderly operation of the filling process and improves the overall stability of the equipment. The ball valve allows for flexible control of the cleaning agent flow, and the liquid receiving hopper at the bottom of the filling conduit catches dripping liquid, preventing waste and contamination. The weight sensor at the bottom of the filling station on the conveyor belt monitors the filling volume in real time and provides timely feedback to control the filling to stop, further improving filling accuracy.

[0020] As an improvement, the mounting base includes a base and a cover sleeved on the base;

[0021] A guide frame and a connecting frame are provided on one side of the base. The guide frame and the connecting frame are installed on the side of the base through a connecting plate. The discharge pipe passes through the guide frame and the connecting frame in sequence.

[0022] A limiting frame is fixedly installed on the top of the cover, and two sets of the limiting frames are symmetrically arranged. The connecting conduit and the filling conduit are respectively passed through the limiting frames on both sides.

[0023] As an improvement, a drive cylinder is installed on the guide frame, and a connecting ring is connected to the output end of the drive cylinder. The connecting ring is sleeved on the discharge pipe, and the drive cylinder drives the discharge pipe to move in the vertical direction through the connecting ring.

[0024] As an improvement, a connecting block is provided between the connecting frame and the discharge pipe. The connecting block is sleeved on the discharge pipe and moves vertically with the discharge pipe. A liquid receiving hopper is connected to the connecting block. Two sets of liquid receiving hoppers are provided and are movably installed on the connecting block by limiting pins.

[0025] As an improvement, a telescopic cylinder is provided between the base and the cover. Two sets of telescopic cylinders are symmetrically arranged. The telescopic cylinders are installed on the base, and the output end of the telescopic cylinder is connected to the cover. The telescopic cylinder drives the cover to move vertically along the height direction of the base.

[0026] As an improvement, a weight sensor is installed at the bottom of the filling station on the conveyor belt.

[0027] The beneficial effects of this utility model are as follows:

[0028] (1) In this utility model, the mounting base, conveyor belt and filling mechanism have clear division of labor. The conveyor belt accurately transports empty bottles, and the filling mechanism is responsible for filling. The control box on one side of the mounting base and the bottom of the filling station of the conveyor belt are equipped with weight sensors. The control box can control the operation of each component in a coordinated manner to achieve automatic filling. The weight sensor can monitor the filling amount in real time to ensure that the weight of each bottle of cleaning agent meets the standard. The coordinated work of each part ensures the orderliness of the filling process, improves the overall stability of the equipment operation, reduces manual intervention, improves production efficiency, and reduces the error and pollution risk caused by manual operation.

[0029] (2) The movable piston included in the filling conduit of this utility model can move up and down along the axial direction of the discharge pipe to control the filling state. The baffle of the movable piston is provided with through holes distributed in the circumferential direction. The through holes enable the cleaning agent to flow evenly. At the same time, the bottom of the baffle is provided with a limiting groove, which corresponds to the limiting protrusion on the top of the filling head. This matching structure can ensure that when filling stops, the flow channel of the filling head and the baffle can be accurately aligned, thereby reducing filling errors and improving filling accuracy.

[0030] (3) In this utility model, the telescopic part of the connecting pipe is flexibly designed. The driving cylinder drives the discharge pipe to move vertically through the connecting ring, while the telescopic cylinder drives the cover to move vertically along the height direction of the base. The flexible telescopic part can adapt to the position change of the discharge pipe, and the height of the discharge pipe and the cover is adjustable. This design allows the equipment to be adapted to packaging bottles of different heights, thereby expanding the applicability of the equipment.

[0031] (4) In this utility model, a liquid receiving hopper is installed on the connecting block. The liquid receiving hopper is installed by means of a limiting pin. The connecting block and the discharge pipe move synchronously to control the opening and closing of the liquid receiving hopper. The liquid receiving hopper can catch the cleaning agent dripping after filling, avoid waste, and at the same time prevent the cleaning agent from contaminating the equipment and packaging bottles, and keep the working environment clean.

[0032] (5) In this utility model, the metal hose and the switch ball valve work together to achieve stable delivery of the cleaning agent. The switch ball valve can accurately control the flow of the cleaning agent, and by adjusting the degree of valve opening and closing, the liquid flow rate can be stably controlled, effectively avoiding delivery interruption or sudden flow changes, thereby ensuring that the cleaning agent flows continuously and steadily to the filling component.

[0033] In summary, this utility model has the advantages of high efficiency, improved processing efficiency, stability and safety, and convenient operation, and is especially suitable for the field of liquid filling technology. Attached Figure Description

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0051] Example 1:

[0052] like Figures 1-13 As shown, an automatic filling machine for a highly stable water-based cleaning agent includes:

[0053] Mounting base 1, conveyor belt 2, and filling mechanism 3;

[0054] A control box 10 is provided on one side of the mounting base 1, which allows operators to monitor and adjust the operating parameters of the equipment at any time, such as the speed of the conveyor belt and the filling volume. It can be quickly adjusted according to the filling requirements of different specifications of packaging bottles and cleaning agents, thus improving the convenience of operation.

[0055] The conveyor belt 2 is disposed on one side of the mounting base 1. The conveyor belt 2 is used to transport the packaging bottles without the need for manual handling, which not only saves labor costs, but also ensures the continuity and stability of the packaging bottle transport.

[0056] The filling mechanism 3 is mounted on the mounting base 1;

[0057] The filling mechanism 3 includes a metal hose 31, a connecting conduit 32, a switch ball valve 33, and a filling conduit 34. The metal hose 31, the connecting conduit 32, the switch ball valve 33, and the filling conduit 34 are connected in sequence. The metal hose 31 has good flexibility and corrosion resistance. High-stability water-based cleaning agents may contain certain chemical components. The metal hose can effectively resist their corrosion and extend its service life. At the same time, the flexibility allows the metal hose to be flexibly adjusted to adapt to different material supply pipeline layouts, which provides convenience during equipment installation and maintenance.

[0058] The on / off ball valve 33 can quickly open and close the channel with a rapid response. When the packaging bottle moves to the filling station, the on / off ball valve 33 opens to allow the cleaning agent to pass through smoothly. After filling is completed, it can be quickly closed to accurately control the start and end time of filling, thereby ensuring that the filling volume of each packaging bottle is consistent and improving the stability of product quality. Moreover, the on / off ball valve 33 has a simple structure, is easy to maintain, and is easy to repair and replace when a fault occurs, reducing equipment downtime.

[0059] The filling conduit 34 is positioned above the conveyor belt 2 and corresponds to the filling station. It ensures that the cleaning agent is accurately injected into the packaging bottle and reduces spillage. The diameter of the conduit can be designed according to the diameter of the packaging bottle and the filling speed to make the outflow speed of the cleaning agent moderate. It will not cause splashing due to excessive flow rate, nor will it affect the filling efficiency due to excessive flow rate.

[0060] The cleaning agent flows through the metal hose 31 and the connecting conduit 32 to the filling conduit 34. After the packaging bottle is moved to the filling station by the conveyor belt 2, the cleaning agent is filled through the filling conduit 34.

[0061] Furthermore, the filling conduit 34 includes a discharge pipe 341, a connecting pipe 342, and a movable piston 343. The discharge pipe 341 is vertically arranged, which allows the cleaning agent to flow out smoothly by gravity, reducing residue or spillage caused by deviation in the flow direction. The vertical discharge path naturally matches the opening direction of the packaging bottle. When the packaging bottle arrives at the filling station via the conveyor belt 2, the vertical discharge pipe can be accurately aligned with the bottle mouth, reducing the probability of the cleaning agent splashing out of the bottle. At the same time, the vertically arranged discharge pipe facilitates internal cleaning and maintenance, reduces the residue accumulation of cleaning agent on the pipe wall, and ensures the purity of each filling.

[0062] The discharge pipe 341 is fixedly connected to the connecting pipe 342, which plays a stable transition role. It can stably deliver the cleaning agent from the switch ball valve 33 to the discharge pipe 341. The fixed connection avoids the pipe loosening caused by equipment vibration, reduces the risk of leakage, and ensures the sealing of the cleaning agent during the transmission process. In addition, the connecting pipe 342 can be designed with a suitable length and angle according to the actual filling height requirements, so that the discharge pipe 341 and the packaging bottle on the conveyor belt 2 maintain the optimal distance, taking into account both filling efficiency and safety.

[0063] The movable piston 343 is inserted into the discharge pipe 341. The movable piston 343 moves up and down along the axial direction of the discharge pipe 341. When filling is required, the movable piston 343 moves upward to open the discharge channel. The cleaning agent is injected into the packaging bottle through the discharge pipe under the action of pressure and gravity. When the filling is close to the preset amount, the movable piston 343 moves downward to gradually reduce the cross-sectional area of ​​the discharge port, slow down the flow rate, and finally completely close the channel to avoid overfilling due to inertia.

[0064] It should be noted that the up-and-down movement of the movable piston 343 can adapt to the filling needs of different sized bottles. For small-capacity bottles, the piston can move down in advance to reduce the flow rate and avoid overflow. For large-capacity bottles, the piston remains in an upward position to maintain a larger flow rate and improve filling efficiency. In addition, the tight fit between the movable piston 343 and the discharge pipe 341 can form a good seal, blocking the flow of cleaning agent when not filling and preventing dripping. This reduces material waste and ensures the cleanliness of the filling station.

[0065] Furthermore, the connecting pipe 342 includes a first connecting part 3421, a telescopic part 3422, and a second connecting part 3423, which are sequentially connected. The first connecting part 3421 is connected to the switch ball valve 33. The telescopic part 3422 is flexibly designed, and its flexibility gives it good tensile and bending capabilities, allowing it to adapt to slight positional deviations or vibrations that may occur during equipment operation. For example, when the conveyor belt 2 experiences slight shaking due to load changes, or when the filling mechanism 3 experiences slight displacement after long-term use, the telescopic part 3422 can offset these effects through its own deformation, preventing rigid tension between the connecting pipe and upstream and downstream components and protecting the sealing at the interface. In addition to improving connection strength, this flexible design also facilitates the installation, debugging, and maintenance of the equipment. When adjusting the height or position of the discharge pipe 341 to adapt to different packaging bottle specifications, the telescopic part can flexibly extend and bend without requiring large-scale disassembly and modification of the entire pipeline, greatly improving the adaptability and ease of operation of the equipment. The second connecting part 3423 is fixedly connected to the discharge pipe 341. In the cleaning agent transmission path from the switch ball valve 33 to the discharge pipe 341, the solid connection at both ends ensures the sealing and reliability of the key interface, and the deformation capability of the flexible telescopic part in the middle can cope with various working condition changes, so that the highly stable water-based cleaning agent remains stable and efficient during the transmission process, further improving the operational stability and practicality of the entire filling system.

[0066] The movable piston 343 includes a pull rod 3431 and a baffle 3432;

[0067] One end of the pull rod 3431 is connected to the cylinder 3433, which is installed on the top of the discharge pipe 341. The cylinder 3433 drives the pull rod 3431 to move vertically. The cylinder 3433 is preferably a thin cylinder. The thin cylinder has a small axial dimension, so when installed on the top of the discharge pipe 341, it will not increase the overall height of the equipment too much. It is especially suitable for production line layouts with limited space. At the same time, the thin cylinder is lighter, which can reduce the load on the top connection structure of the discharge pipe 341, reduce structural wear after long-term operation, and extend the service life of the equipment. Despite its small size, the thin cylinder can still provide stable driving force to ensure the accuracy and response speed of the pull rod 3431 moving vertically. It meets the needs of the baffle 3432 to lift quickly during the filling process, while also taking into account the compactness of the equipment.

[0068] The baffle 3432 is disposed at the other end of the pull rod 3431 and is fixedly connected to the pull rod 3431. The baffle 3432 has several sets of through holes 3434 distributed along the circumference of the baffle 3432. These circumferentially distributed through holes 3434 further enhance the fine flow regulation. When the baffle 3432 moves upward, the area of ​​the annular channel formed by the through holes 3434 and the inner wall of the discharge pipe 341 increases, allowing the cleaning agent to flow out quickly through the multiple sets of through holes 3434, thus dispersing the material when it enters the filling channel. To ensure a uniform flow of multiple streams and prevent high-speed impact of a single material stream on the piston or container wall, this design reduces material splashing or container vibration caused by impact, making it suitable for the rapid filling stage of large-capacity packaging bottles. When the baffle 3432 moves downward, the channel area shrinks, and the flow rate decreases uniformly, enabling "slow filling" when approaching the preset filling volume. This effectively counteracts liquid inertia, reduces overfilling errors, and the circumferentially distributed through holes ensure even force distribution when the cleaning agent flows out, preventing bubbles or splashing caused by local turbulence and protecting the component stability of the highly stable water-based cleaning agent. A limiting groove 3435 is provided at the bottom of the baffle 3432.

[0069] Furthermore, a filling head 3411 is connected to the bottom end of the discharge pipe 341. A flow channel 3412 is provided in the center of the filling head 3411, and a limiting protrusion 3413 is provided on the top of the filling head 3411. The limiting protrusion 3413 is correspondingly provided with a limiting groove 3435 on the baffle 3432. When the baffle 3432 moves downward under the drive of the cylinder 3433, the limiting protrusion 3413 will gradually embed into the limiting groove 3435, forming a precise mechanical limit. This can strictly control the downward movement of the baffle 3432, avoid excessive movement of the baffle 3432 and damage to the filling head or itself, and ensure the safety of equipment operation. Moreover, this corresponding cooperation can also enhance the sealing effect. When the limiting protrusion is fully embedded in the limiting groove, the two are tightly fitted, which can effectively block the flow of cleaning agent, prevent leakage after filling, further reduce material waste, and keep the filling station clean.

[0070] Furthermore, the mounting base 1 includes a base 11 and a cover 12 sleeved on the base 11;

[0071] A guide frame 111 and a connecting frame 112 are provided on one side of the base 11. The guide frame 111 and the connecting frame 112 are installed on the side of the base 11 through a connecting plate 14. This installation method not only ensures the stability of the connection between the guide frame and the connecting frame and the base, but also facilitates the adjustment of their positions according to actual needs. The discharge pipe 341 is sequentially passed through the guide frame 111 and the connecting frame 112. The guide frame 111 can guide the discharge pipe to move stably along a preset path, preventing it from shifting due to its own weight or external vibration during the filling process. The connecting frame 112 further strengthens the fixation of the discharge pipe, ensuring that it remains vertical during up-and-down movement or long-term use, providing a stable structural foundation for accurate filling and reducing the spillage of cleaning agent or deviation in filling position caused by the shaking of the discharge pipe.

[0072] The top of the cover 12 is fixedly equipped with a limiting frame 121. Two sets of limiting frames 121 are symmetrically arranged. The connecting conduit 32 and the filling conduit 34 are respectively passed through the limiting frames 121 on both sides. This design can orderly constrain the connecting conduit and the filling conduit. The limiting frame 121 can fix the pipeline in a preset position to prevent it from swinging randomly due to fluid impact or vibration during equipment operation, and avoid damage caused by friction or collision between pipelines or pipelines with other components. At the same time, it makes the pipeline layout of the entire equipment more regular, which is convenient for later maintenance and repair. The base 11 achieves precise support and guidance for key pipelines through components such as guide frames and connecting frames. The cover 12 achieves equipment protection and pipeline regularity through its own protective function and the limiting frame 121 on the top. The two work together to provide a stable installation foundation for all components of the equipment.

[0073] In addition, a drive cylinder 113 is installed on the guide frame 111. A connecting ring 114 is connected to the output end of the drive cylinder 113. The connecting ring 114 is sleeved on the discharge pipe 341. The drive cylinder 113 drives the discharge pipe 341 to move vertically through the connecting ring 114. The connection method of the connecting ring 114 sleeved on the discharge pipe 341 ensures a stable connection with the discharge pipe and allows it to move synchronously with the drive cylinder, making the lifting and lowering process of the discharge pipe smooth and without shaking. At the same time, the connecting ring 114 and the guide frame 111 are connected vertically. The cooperation of the guide frame 111 ensures that the discharge tube always moves along the path defined by the guide frame when moving vertically, avoiding deviation and ensuring that the filling head is accurately aligned with the bottle mouth, further improving filling accuracy. The drive cylinder 113, as a power source, can provide stable and controllable driving force. Through the extension and retraction of the output end, it drives the connecting ring 114 and the discharge tube 341 to move in the vertical direction. This design can flexibly adjust the height of the discharge tube 341 and the bottom filling head 3411 according to the different heights and sizes of packaging bottles, ensuring that the filling head and the bottle mouth always maintain the optimal distance.

[0074] Meanwhile, after filling is completed, the upward movement of the discharge pipe 341 driven by the drive cylinder 113 can also cleverly control the opening and closing of the receiving hopper. When filling is completed and the discharge pipe moves upward, the originally separated receiving hopper will close to catch the small amount of cleaning agent remaining in the filling head, preventing it from dripping onto the conveyor belt or the outer wall of the packaging bottle, thus keeping the production environment clean. When a new round of filling begins and the discharge pipe moves downward, the receiving hopper opens without affecting the normal discharge of the filling head. This linkage design eliminates the need for an additional drive device to control the receiving hopper, simplifying the equipment structure, reducing the probability of failure, and also reducing the waste of cleaning agent and pollution to subsequent processes, making the filling process more efficient and environmentally friendly.

[0075] Furthermore, a connecting block 115 is provided between the connecting frame 112 and the discharge pipe 341. The connecting block 115 is sleeved on the discharge pipe 341 and moves vertically with the discharge pipe 341. A liquid receiving hopper 116 is connected to the connecting block 115. Two sets of liquid receiving hoppers 116 are provided. The liquid receiving hoppers 116 are movably installed on the connecting block 115 through a limiting pin 117.

[0076] The liquid receiving hopper 116 is shaped like a hopper and includes a receiving part 1161 and an adjusting part 1162. The receiving part 1161 and the adjusting part 1162 are fixedly connected. The adjusting part 1162 is provided with a sliding groove 1163. The end of the adjusting part 1162 is provided with a limiting hole 1164 corresponding to the limiting pin 117. The limiting pin 117 passes through the limiting hole 1164, which provides a stable rotation fulcrum for the liquid receiving hopper 116 and ensures its smooth rotation, avoiding jamming and ensuring that the liquid receiving hopper 116 can open and close in time when the filling head 3411 moves up and down.

[0077] The bottom of the connecting frame 112 extends downward with a fixing block 1121. A limiting block 1122 is provided on the fixing block 1121 corresponding to the slide groove 1163. The fixing block 1121 and the limiting block 1122 cooperate to provide reliable external limiting support for the operation of the liquid receiving hopper. The setting of the fixing block 1121 makes the position of the limiting block 1122 more stable and will not shift due to slight vibration of the connecting frame 112, thus ensuring the accuracy of the cooperation with the slide groove 1163.

[0078] When the connecting block 115 moves upward with the discharge pipe 341, the receiving hopper 116, being movably connected to the connecting block 115 via the limiting pin 117, will synchronously generate a displacement tendency. Meanwhile, the limiting block 1122 is fixed at the bottom of the connecting frame 112 and remains stationary. The sliding groove 1163 on the receiving hopper 116 will slide relative to the limiting block 1122. Due to the guiding constraint of the sliding groove 1163, the receiving hopper 116 will rotate around the limiting pin 117, ultimately achieving the action of closing inward and opening outward on both sides of the receiving hopper 116.

[0079] Furthermore, a telescopic cylinder 13 is provided between the base 11 and the cover 12. Two sets of telescopic cylinders 13 are symmetrically arranged. The telescopic cylinders 13 are mounted on the base 11, and their output ends are connected to the cover 12. The telescopic cylinders 13 drive the cover 12 to move vertically along the height direction of the base 11. The two sets of symmetrically arranged telescopic cylinders 13 can provide a balanced driving force for the movement of the cover 12, preventing the cover from tilting or jamming due to uneven force during lifting and lowering, and ensuring its smooth movement in the vertical direction. This symmetrical layout makes the force on the cover more reasonable, reduces failures caused by unilateral wear after long-term use, and extends the service life of the equipment.

[0080] It should be noted that a weight sensor 21 is installed at the bottom of the filling station on the conveyor belt 2 to monitor the weight change of the packaging bottle at the station in real time. When the packaging bottle moves to the filling station via the conveyor belt 2 and begins filling, the weight sensor can capture the weight data during the cleaning agent injection process in real time and transmit the data to the control box 10. The control box 10 can compare the preset filling weight with the data fed back by the sensor. Once the preset value is reached, it immediately controls the switch ball valve 33 to close or the moving piston 343 to move to stop filling.

[0081] Working process: First, the packaging bottle is conveyed by the conveyor belt 2 and moves towards the filling station along the path on one side of the mounting base 1. At the same time, the cleaning agent is delivered to the switch ball valve 33 through the metal hose 31 and the connecting conduit 32. When the packaging bottle is about to reach the filling station, the control box 10 adjusts the height of the discharge pipe 341 by driving the cylinder 113 according to the preset parameters, so that the filling head 3411 and the bottle mouth of the bottle to be filled are kept at an appropriate distance. At this time, the liquid receiving hopper 116 is in the open state under the cooperation of the limit block 1122 and the slide 1163, which does not affect the filling.

[0082] After the packaging bottle arrives at the filling station, the weight sensor 21 starts to monitor the weight of the bottle in real time. The control box 10 instructs the switch ball valve 33 to open. The cleaning agent enters the filling conduit 34 through the connecting conduit 32 and the switch ball valve 33. The cylinder 3433 drives the pull rod 3431 to move the baffle 3432 upward, increasing the flow area to achieve rapid filling. When the amount is close to the preset amount, the baffle 3432 moves downward to reduce the area and turns to slow filling.

[0083] When the weight sensor 21 detects that the weight of the cleaning agent in the bottle has reached the preset value, the control box 10 immediately commands the switch ball valve 33 to close. At the same time, the cylinder 3433 drives the baffle 3432 to move down, so that the bottom limiting groove 3435 of the baffle 3432 fits and seals with the limiting protrusion 3413 of the filling head 3411 to prevent leakage.

[0084] After filling is completed, the drive cylinder 113 moves the discharge pipe 341 upward, and the liquid receiving hopper 116 moves with the connecting block 115. Under the action of the limiting block 1122 and the slide 1163, it closes inward around the limiting pin 117 to catch the residual cleaning agent from the filling head. Then the conveyor belt 2 sends the filled bottles away, and new empty bottles enter the filling station to repeat the above process.

[0085] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
