Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vinegar packaging, in particular to a high-efficiency vinegar filling device. BACKGROUND

[0002] As a widely used condiment in daily life, the filling efficiency and quality of vinegar directly affect the economic benefits and product market competitiveness of production enterprises. The traditional vinegar filling process mainly relies on manual or semi-automatic equipment, which has problems such as slow filling speed, low precision, and easy spilling. Especially on high-speed production lines, it is difficult to meet the large-scale and high-stability filling demand. Although the existing filling equipment has achieved partial automation, there are still technical bottlenecks in bottle positioning, sealing and filling, and air pressure balancing, which leads to problems such as uneven liquid level, bottle mouth pollution, or gas residue during the filling process.

[0003] At present, common filling devices mostly use mechanical quantitative pumps or gravity filling methods. Although mechanical pump filling can achieve quantitative control, it is easy to cause filling quantity fluctuation due to the influence of vinegar viscosity and bubbles. Gravity filling relies on liquid level difference, which is difficult to adapt to the precise filling demand of different bottle types. In addition, the positioning of traditional equipment for packaging bottles mostly uses mechanical baffles or photoelectric sensors, and the positioning accuracy is greatly affected by the transmission speed. High-speed operation can easily cause bottle deviation, and then cause the filling nozzle and bottle mouth to lose alignment.

[0004] In the sealing and filling link, the existing technology usually adopts rigid filling head to hard contact with the bottle mouth, which can easily cause sealing not to be strict due to the size tolerance or positioning error of the bottle mouth, resulting in liquid leakage or external air entering. More importantly, the problem of air discharge and air pressure balancing in the bottle during the filling process has been ignored for a long time. Most devices directly discharge air through the side hole of the filling head, but no air pressure feedback mechanism is established, resulting in inaccurate liquid level control.

[0005] The lack of air pressure balancing technology further exacerbates the above problems. When vinegar is filled, if the air in the bottle cannot be discharged in time, it will form counter pressure to hinder the flow of liquid; and if the forced air discharge is not properly handled, it may cause liquid splashing or oxidation.

[0029] The beneficial effects of this invention are: 1. High-precision positioning and stable transmission improve filling efficiency. The transmission and positioning components work together to ensure that the packaging bottles are accurately positioned at the filling station, ensuring that the packaging bottles are quickly and accurately aligned with the filling nozzle. It is suitable for high-speed continuous filling production lines. In conjunction with the clamping components, it can effectively position the packaging bottles and avoid filling errors caused by offset or vibration.

[0030] 2. Adaptive sealing and clamping prevent liquid leakage. The clamping component and the lifting bracket are linked to automatically clamp the bottle body during filling, preventing bottle displacement due to liquid impact or air pressure changes. The sealing stopper fits tightly with the bottle mouth to form a dynamic seal, preventing vinegar from splashing out and ensuring accurate feedback from the air pressure self-balancing component. The telescopic cylinder drives the lifting bracket to ensure that the contact pressure between the sealing stopper and the bottle mouth is adjustable, preventing leakage caused by overpressure damaging the bottle mouth or insufficient sealing.

[0031] 3. Pressure self-balancing control enables precise liquid level filling. The pressure self-balancing component monitors changes in bottle pressure in real time and provides feedback to the feed control component via a piston rod. When vinegar is poured in, air enters the pressure balance chamber, pushing the piston rod. The feed passage is automatically adjusted based on the piston rod displacement to ensure precise and controllable filling level, preventing overfilling or underfilling. A one-way valve, working in conjunction with the venting control component, can close the vent during filling and automatically open it after filling, ensuring rapid reset of the pressure balance chamber and improving continuous filling efficiency.

[0032] 4. Automated closed-loop control reduces manual intervention. The entire filling process (positioning → clamping → sealing → filling → venting → resetting) is automatically completed by mechanical linkage, eliminating the need for additional sensors or complex electrical control systems, thus reducing equipment costs and failure rates. The up-and-down movement of the lifting bracket synchronously controls clamping, feeding, and venting. High coordination among all actuators ensures smooth, delay-free operation, making it suitable for high-speed production lines. Magnet and spring reset ensure rapid valve opening and closing response, avoiding the delay issues of traditional solenoid valves and improving filling accuracy and stability.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0036] Example 1 Please see Figure 1 , Figures 4-5 , Figure 9 A high-efficiency vinegar filling device includes a transmission component 1 and a positioning component 2. The transmission component 1 is used to transmit a packaging bottle 8 for filling vinegar, and the positioning component 2 is assembled onto the transmission component 1 and positions the packaging bottle 8.

[0037] It also includes an assembly bracket 31, a lifting bracket 32, and a telescopic cylinder 33. The telescopic cylinder 33 is fixedly installed on the assembly bracket 31 and arranged in the vertical direction. The lifting bracket 32 ​​is fixedly connected to the movable end of the telescopic cylinder 33.

[0038] It also includes a clamping component 4, a pneumatic self-balancing component 5, a feeding control component 6, and an exhaust control component 7. The clamping component 4 is installed on the assembly bracket 31 and is linked with the lifting bracket 32. The clamping component 4 is used to clamp the packaging bottle 8 positioned by the positioning component 2. A sealing plug 321 is fixed on the lifting bracket 32. The sealing plug 321 is used to seal the bottle mouth of the packaging bottle 8 positioned by the positioning component 2. The sealing plug 321 has a feeding passage 322 and an exhaust passage 323.

[0039] The air pressure self-balancing component 5 is installed on the assembly bracket 31, the feeding control component 6 is installed on the lifting bracket 32 ​​and connected to the liquid source of the vinegar being filled, the feeding control component 6 is also used to control the on / off state of the feeding passage 322, the exhaust passage 323 is connected to the air pressure self-balancing component 5, the feeding control component 6 is linked with the air pressure self-balancing component 5 and the assembly bracket 31, and the exhaust control component 7 is installed on the air pressure self-balancing component 5 and is linked with the lifting bracket 32.

[0040] The packaging bottle 8 is stably transported through the path of the transmission component 1. When it passes the positioning component 2, the operating positioning component 2 can transfer the foremost packaging bottle 8 to the clamping component 4 and the sealing plug 321 directly below and accurately position it.

[0041] At this time, the telescopic cylinder 33 is controlled to move and drive the lifting bracket 32 ​​to move downward to the bottom of the stroke, so as to trigger the clamping component 4 to operate and effectively clamp the packaging bottle 8. At the same time, the sealing plug 321 can move downward to achieve a sealing fit with the bottle mouth of the packaging bottle 8.

[0042] When the lifting bracket 32 ​​reaches the bottom of its stroke, it can also trigger the feeding control component 6 to be in the open position. After being pressurized, the vinegar is filled into the packaging bottle 8 through the feeding passage 322. The air in the packaging bottle 8 will be transferred to the air pressure self-balancing component 5 through the exhaust passage 323 under the action of the input vinegar, thereby triggering the operation of the air pressure self-balancing component 5. As the vinegar continues to be filled to the set liquid level, the air introduced into the air pressure self-balancing component 5 gradually increases, and finally the corresponding operation of the air pressure self-balancing component 5 transmits the action to the feeding control component 6, so that the feeding control component 6 is in the closed position again.

[0043] When the lifting bracket 32 ​​reaches the bottom of its travel, it can also trigger the exhaust control component 7 mounted on the air pressure self-balancing component 5 to be in a closed state, preventing the air input into the air pressure self-balancing component 5 from leaking out directly through the exhaust control component 7.

[0044] After the vinegar filling is completed, the lifting bracket 32 ​​is driven by the telescopic cylinder 33 to move from the bottom end of the stroke to the top end. During this process, the clamping component 4 can automatically reset and release its clamping effect on the packaging bottle 8, while the feeding control component 6 remains closed due to the combined action of the air pressure self-balancing component 5 and the assembly bracket 31 to prevent vinegar from spilling. Furthermore, the movement of the lifting bracket 32 ​​can be transmitted to the exhaust control component 7, which in turn controls the exhaust component to open, so as to exhaust the air stored in the air pressure self-balancing component 5 and reset it, thereby ensuring the stable filling of the next packaging bottle 8 with vinegar.

[0045] After the vinegar filling of the packaging bottle 8 positioned by the positioning component 2 is completed, the positioning component 2 continues to operate to transfer the packaging bottle 8 to the downstream side of the transmission component 1. The transmission component 1 then drives the bottle 8 to the downstream process and repositions the empty packaging bottle 8 on the upstream side for vinegar filling.

[0046] Example 2 Please see Figures 1-3 To ensure the stable installation and operation of the transmission component 1 and to achieve stable transmission of the packaging bottle 8, the following technical solution is provided.

[0047] The transmission assembly 1 includes a mounting bracket 11, a transmission roller 12, a transmission belt 13, and a drive motor A14. The transmission roller 12 is rotatably mounted in the mounting bracket 11 and kept in parallel arrangement. The transmission belt 13 is wound around the two sets of transmission rollers 12 and is arranged taut. The packaging bottle 8 is placed on the transmission belt 13 for transmission. The drive motor A14 is fixedly mounted on the mounting bracket 11 and is poweredly connected to one of the sets of transmission rollers 12.

[0048] The mounting bracket 11 ensures that the transmission roller 12, the transmission belt 13 and the drive motor are installed stably according to the set requirements, and prevents the packaging bottles 8 transmitted by the transmission belt 13 from falling off from both sides.

[0049] When the drive motor A14 is working, it drives the transmission roller 12 directly connected to it to run stably. Then, another set of transmission rollers 12 cooperates to drive the transmission belt 13 to run stably, so as to achieve stable transmission of the packaging bottle 8.

[0050] The assembly bracket 31 can also be fixedly installed on the mounting bracket 11 to form a stable whole, thereby improving the structural stability of the device and ensuring that each component operates stably according to the set requirements.

[0051] To ensure that the positioning component 2 can be installed in conjunction with the transmission component 1, and that the positioning component 2 can effectively position the packaging bottle 8 during operation, the following technical solution is provided.

[0052] The mounting bracket 11 has a clearance opening 111, and a horizontally arranged support plate 112 is fixedly installed at the bottom of the clearance opening 111. The support plate 112 is arranged on the transmission belt 13, and transition slopes are provided on both sides of the support plate 112.

[0053] The positioning assembly 2 includes a mounting shaft 21, a positioning disc 22, a drive shaft 23, and a drive motor B24. The mounting shaft 21 includes two sets of shafts rotatably mounted on the mounting bracket 11 and arranged vertically. The two sets of mounting shafts 21 are located outside the clearance opening 111 and are symmetrically arranged. The positioning disc 22 is coaxially fixed to the mounting shaft 21 and is located at the clearance opening 111. The bottom of each mounting shaft 21 is coaxially fixed with a transmission bevel gear 211. The outer edge of the positioning disc 22 is evenly provided with positioning arc grooves 221 that fit against the outer wall of the packaging bottle 8. The drive shaft 23 is rotatably mounted on the mounting bracket 11 and is arranged horizontally. Two sets of symmetrically arranged drive bevel gears 231 are fixed to the drive shaft 23. The two sets of drive bevel gears 231 are respectively engaged with the two sets of transmission bevel gears 211. The drive motor B24 is fixedly mounted on the mounting bracket 11 and is poweredly connected to the drive shaft 23.

[0054] The placement of the clearance opening 111 ensures that the positioning plate 22 in the positioning assembly 2 extends into the mounting bracket 11 and cooperates with the transported packaging bottle 8. When the drive motor B24 is running, it can drive the transmission bevel gear 211, the mounting shaft 21, and the positioning plate 22 to operate stably through the drive shaft 23 and the drive bevel gear 231 on it. Since the two sets of drive bevel gears 231 are symmetrically arranged, it can ensure that the two sets of mounting shafts 21 and the positioning plate 22 mounted on them always maintain the same speed and reverse rotation. Then, the continuously running positioning arc groove 221 positions the packaging bottle 8 transported from the upstream side one by one and transfers it to the support assembly and the sealing plug 321 directly below.

[0055] The support plate 112 provides stable support for the packaging bottle 8 being filled with vinegar, while the ramps on both sides allow the packaging bottle 8 to be stably transferred from the conveyor belt 13 to the support plate 112, or from the support plate 112 to the conveyor belt 13.

[0056] Example 3 Please see Figures 4-5 To ensure that the clamping component 4 can be stably installed on the mounting bracket 31 and can be linked with the lifting bracket 32, and to ensure that the clamping component 4 can effectively clamp the packaging bottle 8, the following technical solution is provided.

[0057] The clamping assembly 4 includes two sets of main connecting rods 41, secondary connecting rods 42, and clamps 43 arranged symmetrically. The top end of the main connecting rod 41 is hinged to the mounting bracket 31. The clamps 43 are fixed to the bottom end of the main connecting rod 41 and are nested and fitted with the packaging bottle 8. The two ends of the secondary connecting rod 42 are hinged to the middle section of the main connecting rod 41 and the lifting bracket 32, respectively.

[0058] When the lifting bracket 32 ​​moves downwards driven by the telescopic cylinder 33, it can drive the bottom ends of the two sets of main connecting rods 41 to move closer to each other through the corresponding secondary connecting rod 42. When the sealing plug 321 moves downwards with the lifting bracket 32 ​​and is nested and sealed with the bottle mouth of the packaging bottle 8, the two sets of clamps 43 can clamp the outer wall of the packaging bottle 8 by the corresponding main connecting rod 41, thereby achieving effective clamping of the packaging bottle 8.

[0059] Example 4 Please see Figure 1 , Figures 4-6 To ensure that the air pressure self-balancing component 5 can be stably assembled and operated on the assembly bracket 31, the following technical solution is provided.

[0060] The pneumatic self-balancing assembly 5 includes a cylinder 51, a front cover 52, a rear cover 53, a piston seat 54, a piston rod 55, and a return spring. The cylinder 51 is fixedly installed on the mounting bracket 31 and arranged horizontally. The front cover 52 and the rear cover 53 are respectively assembled to the front and rear ends of the cylinder 51. The piston seat 54 is slidably inserted into the cylinder 51. The piston rod 55 is fixed to the axis of the piston seat 54 and is slidably inserted into the front cover 52. The feed control assembly 6 is linked with the piston rod 55. The return spring is sleeved around the piston rod 55 and its two ends are respectively in contact with the front cover 52 and the piston seat 54.

[0061] A connecting seat 311 is fixedly installed on the assembly bracket 31, and the cylinder 51 is fixedly installed in the connecting seat 311 to achieve stable installation of the cylinder 51 on the assembly bracket 31. The front cover 52 can ensure that the piston rod 55 slides stably along the axial direction, and the front cover 52 is provided with a vent 521. The rear cover 53, the cylinder 51, and the piston seat 54 together form a pressure balance chamber. When the air discharged from the packaging bottle 8 is delivered to the pressure balance chamber through the exhaust passage 323, it will push the piston seat 54 and the piston rod 55 to move towards the front cover 52. At this time, the return spring is compressed and stores elastic potential energy, and the air in front of the piston seat 54 can be discharged through the vent 521 to ensure the normal movement of the piston seat 54.

[0062] When the air stored in the pressure balance chamber is discharged through the exhaust control component 7, the reset spring releases its elastic potential energy and pushes the piston seat 54 and piston rod 55 toward the rear end cover 53 until they are reset.

[0063] During this process, the piston rod 55, which moves along the axis, can transmit the operating action to the feed control component 6, so as to effectively adjust the opening and closing posture of the feed control component 6.

[0064] Example 5 Please see Figures 6-8 To ensure that the feeding control component 6 can be stably assembled on the lifting bracket 32 ​​and achieve linkage with the piston rod 55 and the assembly bracket 31, so as to accurately control the opening and closing posture by means of the position and posture of the lifting bracket 32 ​​and the liquid level of vinegar in the packaging bottle 8, the following technical solution is provided.

[0065] The feeding control assembly 6 includes a valve seat A61, a valve core A62, a first spring 63, a second spring 64, a first guide rod 65, a second guide rod 66, and a pin seat 67. The valve seat A61 is fixed to the lifting bracket 32, and a connecting passage 611 is provided on the valve seat A61, which is arranged vertically and connects to the feeding passage 322. The top end of the connecting passage 611 is connected to the liquid source of the vinegar being filled. The valve core A62 is slidably inserted into the valve seat A61 and is arranged horizontally. The valve core A62 has a valve hole A621 arranged opposite to the connecting passage 611. Spring 63 is assembled to the periphery of valve core A62 and abuts against valve seat A61. Guide rod 65 is slidably inserted into mounting bracket 31 and arranged vertically. Guide rod 66 is fixed to the bottom of mounting bracket 31 and arranged vertically. Guide rod 65 and guide rod 66 are both inserted into valve seat A61 and associated with both ends of valve core A62. Pin seat 67 is fixed to the top of guide rod 65 and associated with piston rod 55. Spring 64 is sleeved on the periphery of guide rod 65 and abuts against pin seat 67 and mounting bracket 31 at both ends.

[0066] In its natural state, the first spring 63 can drive the valve core A62 to move towards the side where the first guide rod 65 is located, thereby causing the pin hole A to be misaligned with the connecting passage 611, thus disconnecting the vinegar supply passage. When the lifting bracket 32 ​​drives the valve seat A61 and the components assembled therein to the bottom of the stroke, the second guide rod 66 applies force to the valve core A62, causing the valve core A62 to overcome the resistance of the first spring 63 and move towards the second guide rod 66, thereby aligning the valve hole A621 with the connecting passage 611. At this time, the pressurized vinegar supplied by the liquid source can be transported to the bottom packaging bottle 8 through the connecting passage 611, the valve hole A621, and the feed passage 322.

[0067] The second spring 64 can apply an upward force to the first guide rod 65 and the pin seat 67, so that the pin seat 67 always maintains a mutually abutting posture with the piston rod 55.

[0068] As the vinegar is gradually filled to the set level, the piston rod 55 moves accordingly, causing the first guide rod 65 to descend, which in turn moves the valve core A62 toward the first guide rod 65, so that the valve hole A621 is misaligned with the connecting passage 611 and the continued supply of vinegar is blocked.

[0069] After the vinegar filling is completed, the lifting bracket 32 ​​moves upward. At this time, the first guide rod 65 is still moving downward relative to the valve core, which can still keep the valve core A62 in the same position on this side and remain in the closed / open state until the action of the second guide rod 66 on the valve core A62 is canceled, and the first spring 63 applies an action to the valve core A62 to keep it in the normally closed state.

[0070] To ensure that the first guide rod 65 and the second guide rod 66 can adjust the position and attitude of the valve core A62, the following technical solution is provided.

[0071] The valve core A62 is equipped with a pin 622 and a magnet A623 at both ends. The second guide rod 66 is equipped with a magnet a661 that attracts the magnet A623. The bottom of the first guide rod 65 is provided with a trapezoidal positioning groove 651. The short side of the trapezoidal positioning groove 651 is arranged close to the valve core A62. The pin 622 is arranged in the trapezoidal positioning groove 651 and abuts against the short side and the inclined side of the trapezoidal positioning groove 651.

[0072] As the lifting bracket 32 ​​moves towards the bottom of its stroke, the valve core A62 moves downward relative to guide rods A and B. At this time, the valve core A62 moves towards the first guide rod 65 under the action of the first spring 63. At this time, the valve rod is close to the long side of the trapezoidal positioning groove 651. The relative movement of the first guide rod 65 will not cause spatial movement interference to the valve core A62 and the pin 622. When the lifting bracket 32 ​​reaches the bottom of its stroke, the magnet a661 on the second guide rod 66 is opposite to the magnet A623 on the valve core A62, thereby attracting the magnet A623 and the valve core A62 to move towards the second guide rod 66, so that the valve hole A621 is connected to the connecting passage 611 and vinegar is supplied. At this time, the pin 622 is driven by the valve core A62 to abut against the short side of the trapezoidal positioning groove 651.

[0073] During the continuous filling of vinegar to the set liquid level, the air discharged from the packaging bottle 8 acts on the air pressure self-balancing component 5, causing the piston rod 55 to move to the front end, thereby driving the pin seat 67 and the first guide rod 65 to move downward. At this time, the pin rod 622 acts on the inclined side of the trapezoidal positioning groove 651, and the inclined side of the trapezoidal positioning groove 651 drives the pin rod 622 and the valve core A62 to move towards the first guide rod 65, so that the feeding control component 6 is in the closed position.

[0074] An extension groove 652 is also provided on the top long side of the trapezoidal positioning groove 651. During the process of the valve core A62 moving upward with the lifting bracket 32, the valve stem can move in the extension groove 652 to avoid the trapezoidal positioning groove 651 causing spatial movement interference to the valve stem.

[0075] In the vinegar filling stage, to ensure that the valve stem moving forward can drive the first guide rod 65 and the pin seat 67 to move downward, the following technical solution is provided.

[0076] The piston rod 55 has guide grooves distributed along the axial direction. The guide grooves include a deep guide groove 551, a sloping guide groove 552, and a shallow guide groove 553 connected sequentially from the front end to the rear end of the piston rod 55. The pin seat 67 is arranged in the guide groove and slides against the guide groove.

[0077] When the piston rod 55 is in the retraction stage, the pin seat 67 abuts against the guide groove 551. At this time, the first guide rod 65 is in a relatively high position. During the process of gradually filling the packaging bottle 8 with vinegar, the piston rod 55 gradually extends. At this time, the pin seat 67 slides relative to the guide groove 551. Before the vinegar is filled to the critical point of the set liquid level, the pin seat 67 interacts with the guide inclined groove 552. Under the action of the guide inclined groove 552, the first guide rod 65 and the pin seat 67 will move downward, thereby triggering the valve core to move relative to the inclined side of the positioning groove, so that the feeding control component 6 is closed, and the pin seat 67 finally abuts against the guide front seat.

[0078] Example 6 Please see Figures 10-11 To ensure that the air output from the exhaust passage 323 can be effectively delivered to the pressure balance chamber, and to ensure that the exhaust control component 7 can be stably assembled on the pressure self-balancing component 5, so as to control the effective exhaust of air from the pressure balance chamber, the following technical solution is provided.

[0079] The rear cover 53 has an air inlet 531 and an exhaust outlet 532. The air inlet 531 is equipped with a one-way valve 533 that controls the air input. The one-way valve 533 is connected to the exhaust passage 323. The exhaust control component 7 is connected to the exhaust outlet 532.

[0080] The exhaust control assembly 7 includes a valve seat B71, a valve core B72, a third spring 73, and a third guide rod 74. The valve seat B71 is fixedly installed on the rear end cover 53. The valve seat B71 has an exhaust through hole 711 arranged horizontally and connected to the exhaust port 532. The valve core B72 is slidably inserted into the valve seat B71 and arranged horizontally. The valve core B72 has a valve hole B721 arranged opposite to the exhaust through hole 711. The third spring 73 is assembled around the valve core B72 and keeps in contact with the valve seat B71. The third guide rod 74 is fixed to the lifting bracket 32 ​​and inserted into the valve seat B71. A magnet B722 is assembled at one end of the valve core B72. A magnet b741 that attracts the magnet B722 is assembled on the third guide rod 74.

[0081] The one-way valve 533 is designed to restrict air to flow only from the packaging bottle 8 to the pressure balance chamber.

[0082] When the lifting bracket 32 ​​is at the bottom of its stroke, the magnet b on the third guide rod 74 and the magnet B722 mounted on the valve core B72 are misaligned. At this time, the third spring 73 can drive the valve core B72 to move away from the third guide rod 74 in its natural state, thereby causing the valve hole B721 to be misaligned with the exhaust hole 711, so as to block the air in the pressure balance chamber from being normally discharged through the exhaust port 532 exhaust hole 711 and the valve hole B721, thereby ensuring that the air discharged during the vinegar filling process can be stored in the pressure balance chamber and drive the piston seat 54 and the piston rod 55 to move forward.

[0083] When the lifting bracket 32 ​​drives the third guide rod 74 to move upward to the top of the stroke, magnet B722 and magnet b741 will be arranged relative to each other. Then, magnet b741 will attract magnet B722 and valve core B72 to move closer to the third guide rod 74, so that the exhaust port 711 and valve port B721 are arranged relative to each other, so as to exhaust the air stored in the air pressure balance chamber. Then, under the action of the return spring, piston seat 54 and piston rod 55 move to the rear end and return to their original positions.
