Description

Technical Field

[0001] This invention relates to the field of bottling equipment technology, specifically to a baijiu (Chinese liquor) metering and bottling equipment. Background Technology

[0002] The bottling of baijiu is a crucial step in the production process, and its precision and hygiene standards directly affect the product's net content, quality stability, and brand reputation.

[0003] Currently, mainstream liquor bottling equipment still faces several technical bottlenecks in achieving precise, aseptic, and adaptive bottling. For example, most equipment uses limit switches or timed controls to open the bottling valve, making it difficult to ensure that the bottling head (liquid outlet) only starts dispensing liquid after touching the bottom of the bottle. This can easily cause liquid splashing and foaming during the initial bottling stage, leading not only to measurement errors but also potentially accelerating the oxidation of liquor.

[0004] Secondly, given the diverse bottle shapes (various heights and diameters) in the market, existing equipment lacks adaptability. Adjusting the filling head height to suit different bottle shapes is often cumbersome, requiring machine shutdown and manual adjustment of multiple mechanical parts, or even replacement of parts. This process is time-consuming and labor-intensive, affecting production efficiency, and it is difficult to guarantee the consistency of accuracy for each adjustment. In addition, during the liquid dispensing process, the traditional filling head causes the liquid to impact the center of the bottle bottom vertically, which can easily cause turbulence and foam, affecting the filling speed and liquid level accuracy.

[0005] Therefore, there is an urgent need for a liquor metering and bottling equipment to solve the above-mentioned technical problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present invention, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] The purpose of this invention is to solve the problems of existing equipment where adjusting the height of the filling head to adapt to different filling needs is cumbersome, time-consuming and labor-intensive, and the vertical impact of the liquid on the bottom center of the bottle during the dispensing process can easily cause turbulence and foam, affecting the filling speed and liquid level accuracy.

[0008] To solve the above-mentioned technical problems, the present invention proposes a liquor metering and filling device, including a frame, a conveying mechanism mounted on the frame, a storage tank and a filling valve, wherein the filling valve is connected to the storage tank via a pipeline, and further includes a first driving mechanism, which is used to drive the filling valve to lift and lower as a whole.

[0009] The bottom of the filling valve is provided with a liquid outlet pipe, which is adapted to extend and retract along the axial direction of the filling valve, and the lower end of the liquid outlet pipe has a liquid outlet.

[0010] A trigger adjustment component is coaxially disposed outside the filling valve. The trigger adjustment component is used to set and lock a fixed trigger distance. Its lower end has a contact surface for abutting against the upper surface of the bottle mouth. The trigger adjustment component is provided with an exhaust channel inside. When the contact surface is sealed against the bottle mouth, the exhaust channel is connected to the space inside the bottle.

[0011] The triggering distance is the axial distance from the contact surface of the triggering adjustment component to the liquid outlet, and the triggering distance is configured to be less than the height of the bottle to be filled.

[0012] A normally closed valve core mechanism is provided between the liquid outlet pipe and the filling valve, and the trigger adjustment component is connected to the valve core mechanism.

[0013] Furthermore, the trigger adjustment component is an abutment block, which is cylindrical and coaxially mounted on the outside of the filling valve. The end of the abutment block has a threaded head, and the lower end of the valve core mechanism has a matching threaded hole. The abutment block is adapted to be screwed into the threaded hole through the threaded head and the trigger distance is set.

[0014] Furthermore, the trigger adjustment component is also provided with an elastic reset member, which is sleeved on the outside of the filling valve. One end of the elastic reset member is fixed to the upper end face of the valve core mechanism, and a fixed seat is provided on the top of the valve core mechanism. The other end of the elastic reset member is connected to the fixed seat.

[0015] Furthermore, the conveying mechanism is provided with a fixing component, which includes a first clamping member and a second clamping member. The first clamping member includes a pair of clamping plates, which are symmetrically arranged on both sides of the conveyor belt. The clamping plates are connected to an adjusting rod, which is equipped with a locking nut and a nut seat.

[0016] Furthermore, the second clamping member includes a connecting plate that is slidably connected to the side of the conveying mechanism, and a gripper is provided at one end of the connecting plate near the conveyor belt. The connecting plate is connected to a cylinder or an electric push rod.

[0017] Furthermore, the exhaust passage includes a first passage and a second passage, the first passage being arranged along the axial direction of the abutment block, and the second passage being arranged along the radial direction of the abutment block and communicating with the first passage.

[0018] Furthermore, the contact surface of the contact block is provided with an elastic sealing layer, which is made of silicone material. The elastic sealing layer is adapted to undergo slight deformation when in contact with the bottle mouth, so as to ensure a seal while avoiding scratching the bottle mouth.

[0019] Furthermore, the conveying mechanism includes a driving roller, a driven roller, and a conveyor belt sleeved between the driving roller and the driven roller, and the driving roller is driven by a drive motor.

[0020] Furthermore, a first lifting assembly is provided at the bottom of the liquid storage tank. The first lifting assembly includes a telescopic rod, one end of which is fixedly connected to the bottom of the liquid storage tank and the other end is fixedly connected to the frame. The telescopic rod is also connected to a telescopic drive source.

[0021] Furthermore, the telescopic drive source is a hydraulic cylinder, which is connected to a hydraulic system. The bottom of the storage tank is provided with a filling port, and a valve is provided at the filling port. The filling port is used to connect to an external liquid supply pipeline to replenish the liquid in the storage tank as needed.

[0022] The beneficial effects of the present invention are as follows: by setting a trigger adjustment component, the trigger adjustment component can set and lock a fixed trigger distance. When the filling valve reaches the trigger distance, the valve core mechanism will expose the outlet of the liquid outlet pipe, thereby fixing the liquid outlet position at the bottom of the bottle. Furthermore, when dealing with different sizes of bottles, only the trigger distance needs to be adjusted. The adjustment process is simple and quick, improving production efficiency.

[0023] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0032] Please see Figures 1 to 6 As shown, the present invention proposes a liquor metering and filling device, including a frame 1, a conveying mechanism 2 mounted on the frame 1, a storage tank 3, and a filling valve 4. The conveying mechanism 2 is used to convey liquor bottles to be filled, the storage tank 3 stores liquor to be filled, and the storage tank 3 and the filling valve 4 are connected by a pipeline to supply liquor.

[0033] Furthermore, the filling valve 4 is provided with a first driving mechanism 41, which is used to drive the filling valve 4 to reciprocate in the vertical direction, thereby moving the filling valve 4 closer to or away from the bottle mouth. The bottom of the filling valve 4 is provided with a liquid outlet pipe 42, and the lower end of the liquid outlet pipe 42 has a liquid outlet 43. The liquid outlet pipe 42 is adapted to extend and retract along the axis of the filling valve 4. A normally closed valve core mechanism 44 is provided between the liquid outlet pipe 42 and the filling valve 4. The valve core structure 44 is sleeved on the liquid outlet pipe 42, so that the liquid outlet pipe 42 remains closed when not filling. When the filling valve 4 approaches the bottle mouth, the first driving mechanism 41 continues to operate, pushing the liquid outlet pipe 42 downward to extend the liquid outlet 43 into the bottle. Then the valve core mechanism 44 opens, allowing the liquid to flow into the bottle through the liquid outlet pipe 42 and the liquid outlet 43.

[0034] Based on the above embodiments, the conveying mechanism 2 includes an active roller, a driven roller, and a conveyor belt 21 sleeved between the active roller and the driven roller. The active roller is connected to a drive motor, which drives the active roller to rotate, thereby driving the conveyor belt 21 to operate and realize the continuous conveying of wine bottles.

[0035] It should be noted that the drive motor should be connected to a control module. This control module is configured to control the start, stop and speed of the drive motor according to the filling process, so as to realize the positioning of the wine bottle at the filling station and intermittent conveying, ensuring that the wine bottle stops accurately below the filling valve 4 each time it is filled, and that the conveyor belt 21 remains stationary during the filling process. This control module can be a programmable logic controller (PLC) or a microcontroller. Its input terminal can be connected to a sensor for detecting the position of the wine bottle, and its output terminal is electrically connected to the drive motor. Automated control is realized through a preset program. For details, please refer to the existing technology, which will not be described in detail in this embodiment.

[0036] For example, the first drive mechanism 41 can be a cylinder or an electric push rod, with its fixed end connected to the frame 1, and the piston rod or output shaft pointing vertically downward and connected to the filling valve 4. The overall lifting and lowering of the filling valve 4 can be achieved by controlling the air intake and exhaust of the cylinder or the start and stop of the motor of the electric push rod.

[0037] To adjust the height of the storage tank 3, a first lifting assembly 31 is provided at the bottom of the storage tank 3. The first lifting assembly 31 includes at least a telescopic rod 32. One end of the telescopic rod 32 is fixedly connected to the bottom of the storage tank 3, and the other end is fixedly connected to the frame 1. The telescopic rod 32 is connected to a telescopic drive source. The telescopic drive source drives the telescopic rod 32 to move, thereby adjusting the vertical height of the storage tank 3. The telescopic drive source can be a hydraulic cylinder 33. The hydraulic cylinder 33 is connected to a hydraulic system. By controlling the extension and retraction stroke of the hydraulic cylinder 33, the height of the storage tank 3 is precisely adjusted to ensure a stable liquid level difference between the storage tank 3 and the filling valve 4, and to ensure a constant flow pressure of the liquid in the pipeline, thereby improving the filling accuracy.

[0038] For example, the number of telescopic rods 32 can be multiple sets, evenly distributed at the bottom of the liquid storage tank 3. Multiple sets of telescopic rods 32 move synchronously to ensure that the liquid storage tank 3 rises and falls smoothly. Therefore, each telescopic rod 32 can be connected to a hydraulic cylinder 33. The extension and retraction stroke of multiple telescopic rods 32 can be controlled simultaneously by a single hydraulic cylinder 33, thereby ensuring that the liquid storage tank 3 is subjected to uniform force and runs stably during the lifting process, and avoiding shaking or tilting caused by uneven load.

[0039] In addition, a filling port 34 is provided at the bottom of the storage tank 3. A valve is provided at the filling port 34. The filling port 34 is used to connect to an external liquid supply pipeline to replenish the liquid in the storage tank 3 in a timely manner to maintain the stability of the liquid level during the bottling process.

[0040] Based on the above embodiments, another embodiment of the present invention is that, in order to fix the wine bottle after it is delivered to the position and prevent the wine bottle from being displaced due to vibration or external force during the filling process, a fixing component is provided on the conveying mechanism 2. The fixing component is used to limit the wine bottle in at least four directions, thereby effectively preventing the wine bottle from shifting or tipping over during the filling process.

[0041] For example, the fixing assembly includes a first clamping member 5 and a second clamping member 6. The first clamping member 5 includes a pair of clamping plates 51, which are symmetrically arranged on both sides of the conveyor belt 21. In order to adapt to the clamping requirements of different sizes of wine bottles, the clamping plates 51 are connected to an adjusting rod 52. The adjusting rod 52 is equipped with a locking nut 53 and a nut seat 54. The distance between the clamping plates 51 can be adjusted by the screwing depth of the adjusting rod 52 into the nut seat 54. The locking nut 53 is used to fix the adjusted position, thereby achieving reliable clamping of wine bottles of different diameters.

[0042] The second clamping member 6 includes a connecting plate 61, which is slidably connected to the side of the conveying mechanism 2. The connecting plate 61 is provided with a clamping claw 62 at one end near the conveyor belt 21. When the wine bottle is conveyed to the filling station, the connecting plate 61 drives the clamping claw 62 to slide towards the wine bottle until the clamping claws 62 on both sides contact the bottle body and clamp and fix it.

[0043] For example, the connecting plate 61 can be connected to a cylinder or an electric push rod, which can be automatically triggered by the control unit to extend or retract. For instance, when the sensor detects that the bottle has reached the designated position, the control unit sends a signal to drive the cylinder or electric push rod to push the connecting plate 61 to move, so that the gripper 62 gradually approaches the bottle until it is clamped in place. It works in conjunction with the first clamping member 5 to achieve multi-directional limiting of the bottle and ensure that the bottle maintains a stable posture during the filling process.

[0044] Based on the above embodiments, in order to prevent damage to the surface of the wine bottle during the clamping process, the side of the clamping plate 51 and the gripper 62 that contacts the bottle body is provided with a buffer pad. The buffer pad is made of food-grade silicone material, which has good elasticity and wear resistance, ensuring stable clamping and effectively preventing the wine bottle from being scratched or broken due to force.

[0045] Based on the above embodiments, another embodiment of the present invention is as follows: In order to make the liquid outlet located at the bottom of the bottle, thereby reducing the contact area between the liquid and air, reducing the risk of oxidation, and reducing foam and splashing generated during the filling process, the device also includes a trigger adjustment component 7. The trigger adjustment component 7 is used to ensure that the liquid outlet pipe 42 only opens to dispensing liquid after reaching the bottom of the bottle. The trigger adjustment component 7 is coaxially disposed outside the filling valve 4, and the trigger adjustment component 7 is used to set and lock a fixed trigger distance. Its lower end has an abutment surface for abutting against the upper surface of the bottle mouth. The trigger distance is the axial distance from the abutment surface of the trigger adjustment component 7 to the liquid outlet 43. During the filling process, after the abutment surface abuts against the bottle mouth, the valve core mechanism is triggered to open the liquid outlet pipe 42, thereby realizing the slow filling of the liquid from the bottom of the bottle.

[0046] For example, the trigger adjustment component can be an abutment block 71, which is cylindrical and coaxially mounted on the outside of the filling valve 4. The abutment block 71 has a threaded head 72 at its end, and the lower end of the valve core mechanism 44 has a matching threaded hole. The abutment block 71 is adapted to be screwed into the threaded hole through the threaded head 72 and its screwing depth is adjusted to set the trigger distance. When the filling valve 4 descends, the lower end face of the abutment block 71 first contacts the upper end face of the bottle mouth. As the filling valve 4 continues to descend, the abutment block 71 will move upward synchronously with the valve core mechanism 44 until the outlet 43 at the lower end of the liquid outlet pipe 42 is exposed. At this time, the wine flows out from the outlet 43 and fills from the bottom of the bottle upward, avoiding the liquid directly impacting the liquid surface and generating bubbles.

[0047] In the above process, the valve core mechanism 44 will only open the liquid outlet 43 when the abutment block 71 makes contact with the bottle mouth and transmits an upward force. Therefore, the trigger distance should be less than the height of the bottle to be filled. After the abutment block 71 makes contact with the bottle mouth, the filling valve 4 can continue to descend to the set trigger distance, so that the liquid outlet 43 is fully exposed.

[0048] Based on the above embodiments, another embodiment of the present invention is as follows: In order to ensure that the valve core mechanism 44 can automatically reset after filling and avoid residual wine dripping and causing contamination, the trigger adjustment component 7 is also provided with an elastic reset member. The elastic reset member is sleeved on the outside of the filling valve 4, one end of which is fixed to the upper end face of the valve core mechanism 44, and a fixed seat is provided on the top of the valve core mechanism 44. The other end of the elastic reset member is connected to the fixed seat. During the filling process, the valve core mechanism 44 will be subjected to an upward force from the abutment block 71, which compresses the elastic reset member. When filling is completed and the filling valve 4 rises, the elastic reset member releases its elastic force, pushes the valve core mechanism 44 down to reset, and re-closes the liquid outlet 43 to ensure that no residual liquid drips after filling.

[0049] For example, the resilient reset element can be a spring 73.

[0050] Based on the above embodiments, another embodiment of the present invention is as follows: In the actual filling process, when the contact block 71 contacts the bottle mouth, it may completely seal the inside of the bottle, causing the air pressure inside the bottle to rise and hindering the smooth flow of the wine, thus affecting the filling efficiency and accuracy. Therefore, the trigger adjustment component 7 is provided with an exhaust channel inside. When its contact surface is sealed against the bottle mouth, the exhaust channel will communicate with the space inside the bottle, allowing the gas inside the bottle to be discharged along the exhaust channel during the filling process, thereby balancing the air pressure difference inside and outside the bottle and ensuring that the wine flows in smoothly.

[0051] For example, the venting channel includes a first channel 74 and a second channel 75. The first channel 74 is arranged axially along the abutment block 71, and the second channel 75 is arranged radially along the abutment block 71 and communicates with the first channel 74. When the abutment block 71 seals against the bottle neck, the first channel 74 communicates with the internal space of the bottle, while the second channel 75 communicates with the outside atmosphere, forming a continuous venting path. During the filling process, the gas inside the bottle is compressed and discharged sequentially through the first channel 74 and the second channel 75, effectively preventing gas pressure buildup. This structure achieves automatic venting while ensuring sealing triggering, improving filling smoothness and accuracy, and is especially suitable for the stringent requirements of liquid flow stability in high-speed filling scenarios.

[0052] Based on the above embodiments, another embodiment of the present invention is that, in order to improve the adaptability to different types of wine bottles during the filling process, the contact surface of the contact block 71 is provided with an elastic sealing layer. The elastic sealing layer is made of food-grade silicone material and can undergo slight deformation when in contact with the bottle mouth, ensuring reliable sealing while avoiding scratching the bottle mouth. Especially when facing bottle mouths with diameter deviation or slight unevenness, it can still maintain good air tightness, further ensuring the consistency of venting effect and filling accuracy.

[0053] Based on the above embodiments, another embodiment of the present invention is that, in order to realize multi-station filling, the filling valve 4 can be set as multiple groups, and the multiple groups of filling valve 4 are arranged in a uniform manner and operate synchronously. They are synchronously driven by the first driving mechanism 41, thereby improving the filling efficiency and meeting the needs of large-scale production.

[0054] Each filling valve 4 is independently equipped with a valve core mechanism 44 and an elastic reset component to ensure that it maintains its own sealing reliability while operating synchronously, and avoids the overall operation from being affected by a single point of failure. The installation and coordinated control of multiple filling valves 4 are well known to those skilled in the art. They can be synchronized and calibrated through a unified drive transmission mechanism or an independent control module. Therefore, they will not be described in detail in this embodiment.

[0055] Based on the above embodiments, another embodiment of the present invention is that, in order to measure the filling process, a flow sensor can be installed at the outlet end of the filling valve 4 to monitor the outflow of wine in real time and feed the signal back to the control system. When the preset filling volume is reached, the control system immediately issues a command to control the filling valve 4 to move upward and cut off the wine passage, thereby realizing quantitative filling.

[0056] For example, the flow sensor can be a Hall effect flow meter or an electromagnetic flow meter, installed in the flow channel between the outlet of the filling valve 4 and the inlet of the wine bottle. The control system can be a PLC controller, which receives the flow sensor signal in real time and performs data calculations, and accurately controls the action sequence of the filling valve 4 in combination with preset parameters. The specific sensor selection and PLC controller data configuration can refer to the prior art, and will not be described in detail in this embodiment.

[0057] Based on the above embodiments, another embodiment of the present invention is that, since the liquid level in the storage tank 3 will change dynamically during the filling process and the replenishment process, in order to maintain a constant filling pressure, a height adjustment device is provided at the inlet of the filling valve 4. The height adjustment device is adapted to adjust the inlet position of the filling valve 4 in real time according to the liquid level in the storage tank 3, so that it is always located below the preset depth below the liquid surface, thereby ensuring the static pressure is stable during the filling process and reducing the flow rate change caused by liquid level fluctuations.

[0058] For example, the height adjustment device can be a closed-loop control system consisting of an electric push rod and a liquid level sensor. The liquid level sensor monitors the liquid level in the storage tank in real time and transmits the data to the PLC controller. The controller outputs an adjustment signal according to a preset algorithm to drive the electric push rod to extend and retract, thereby moving the filling valve inlet up and down so that it is always submerged at a set depth below the liquid surface, ensuring constant static pressure.

[0059] For example, the preset depth can be set between 50mm and 150mm below the liquid surface to balance filling flow rate and bubble control. The liquid level sensor can be one of a float-type liquid level gauge, radar liquid level gauge, or ultrasonic liquid level gauge, installed on the side wall or top of the storage tank. The non-contact or contact measurement method can be selected according to the actual working conditions. The stroke accuracy of the electric actuator is controlled within ±1mm to ensure the accuracy of the adjustment of the filling valve inlet position. The PLC controller can preset the liquid level compensation algorithm to calculate the liquid level change trend in real time and adjust the electric actuator action in advance to eliminate dynamic response lag. Specific control parameters can refer to the existing technology, which will not be described in detail in this embodiment.

[0060] The operation of this equipment is as follows: Based on the filling requirements, the trigger distance is set by adjusting the screw-in depth of the abutment block 71. Then, the conveying mechanism 2 is activated to sequentially transport the bottles to be filled to the filling station. When the bottle reaches the designated position, the fixing component limits the bottle. Then, the first drive mechanism 41 drives the filling valve 4 to move downwards, causing the abutment surface of the trigger adjustment component 7 to contact the bottle mouth. As the filling valve 4 continues to move downwards, the valve core mechanism 44 remains stationary under the resistance of the abutment block 71, thus exposing the outlet 43 at the lower end of the internal outlet pipe 42. At this time, the outlet 43 is located at the bottom of the bottle, thus operating under constant static pressure. When in use, the liquid in the storage tank 3 flows into the inner cavity of the bottle through the outlet 43. As the liquid level gradually rises, the gas inside the bottle is discharged through the exhaust channel. When the filling volume inside the bottle reaches the preset liquid level, the filling valve 4 moves upward, causing the contact surface of the abutment block 71 to separate from the bottle mouth. The valve core mechanism 44 moves downward under the action of the elastic reset element, re-sealing the outlet 43 and stopping the filling. The entire process can always keep the liquid outlet position at the bottom of the bottle, avoiding liquid splashing and foam generation. At the same time, the abutment block 71 achieves a seal inside the bottle, effectively preventing outside air from entering the bottle during the filling process and causing oxidation or contamination, ensuring stable product quality.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
