Description

Technical Field

[0001] This invention relates to the field of liquid filling technology, specifically to a liquid filling device with adjustable height for multiple filling heads. Background Technology

[0002] As the cornerstone of the modern packaging industry, liquid filling technology has always evolved around three core aspects: precision, speed, and hygiene. From gravity-dependent atmospheric pressure filling to isobaric filling that maintains the bubbles in carbonated beverages, and then to vacuum filling that handles viscous liquids, the technical principles have been continuously refined. Meanwhile, automated production lines integrate processes such as cleaning, filling, and capping. Equipment materials and cleaning processes (such as CIP / SIP systems) have also been comprehensively upgraded to meet the stringent hygiene standards of industries such as food and pharmaceuticals. Intelligent control further enhances the flexibility and precision of production.

[0003] Within this general technological framework, juice filling has developed a unique branch of technology. Its core challenge lies in how to strike a balance between sterilization and preservation of natural flavor and nutrition. Traditional hot filling technology achieves reliable sterilization through high-temperature filling, but at the cost of aroma loss and destruction of heat-sensitive nutrients. For this reason, aseptic cold filling technology has been widely used. After ultra-high temperature instantaneous sterilization, it is filled at room temperature in an aseptic environment, which greatly preserves freshness. However, it has extremely strict requirements for equipment, environment and management. In addition, in response to the characteristics of juice such as easy oxidation and pulp content, supporting processes such as nitrogen filling and homogenization treatment have also been developed.

[0004] However, when it is necessary to fill juice and visible fruit pieces together, it touches on the difficult area of ​​current filling technology, namely handling solid-liquid two-phase flow, which brings multiple drawbacks: the primary problem is that the filling ratio is seriously uneven. Due to the different densities of fruit pieces and juice, they are very easy to separate in storage tanks and pipelines, resulting in poor product consistency. Secondly, the physical integrity of fruit pieces is easily damaged. The shearing force during pumping and filling can break up the fruit pieces, affecting the taste and possibly accelerating spoilage.

[0005] Therefore, it is necessary to design a liquid filling device with adjustable height for multiple filling heads that separates fruit granules and fruit juice for filling. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. By setting up a storage tank and a vibrating cylinder, the fruit juice and fruit pieces are filled separately, which effectively prevents the fruit pieces and juice from easily separating in the storage tank and pipeline due to their different densities, resulting in poor product consistency. When conveying fruit pieces, the vibrating cylinder is activated to vibrate and shift the fruit pieces inside, effectively preventing some fruit pieces from accumulating in the corners inside the vibrating cylinder and failing to fall into the conveying bend.

[0018] 2. By setting up the injection assembly, the filling head height can be automatically adjusted during filling of juice bottles of different heights without manual adjustment or sensor scanning. The height is automatically adjusted by the pressure between the outer and inner conical surfaces of the conical block and the bottle mouth, which moves the conical block up and down to accommodate juice bottles of different heights. This achieves high filling efficiency. When the bottle mouth enters the conical block, it is automatically pressed against the bottle mouth to prevent fruit juice from splashing during filling. When the bottle mouth leaves the conical block, a semi-circular cotton strip wipes the top of the bottle mouth to clean up any remaining liquid, effectively preventing excessive fruit juice from splashing onto or around the bottle mouth.

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] Please see Figure 1-9The present invention provides a technical solution: a liquid filling device with adjustable height for multiple filling heads, including a workbench 1, an electric turntable 2 fixedly connected to the upper middle of the workbench 1, a plurality of placement slots evenly provided on the rotating end of the electric turntable 2, a filling mechanism 3 for separately filling fruit juice and fruit pieces on one side of the electric turntable 2, a positioning mechanism 4 for positioning the bottle on one side of the filling mechanism 3, a capping mechanism 5 for placing the bottle cap onto the bottle mouth on one side of the positioning mechanism 4, a capping mechanism 7 for locking the bottle cap onto the bottle mouth on one side of the capping mechanism 5, and a bottle feeding mechanism 8 on one side of the capping mechanism 7.

[0037] The injection mechanism 3 includes a first base 31 fixedly connected to the upper side of the workbench 1. Several support rods 32 are fixedly connected to the upper side of the first base 31. A third upper top plate 34 is fixedly connected to the upper side of the support rods 32. A water pump 33 is fixedly connected to the middle of the third upper top plate 34. A positioning plate 38 is fixedly connected to the lower side of the third upper top plate 34. An outlet head 39 is fixedly connected inside the positioning plate 38. A first hose 35 is fixedly connected to the input end of the outlet head 39, and the other end of the first hose 35 is fixedly connected to the output end of the water pump 33. A separation component 37 is provided on the upper side of the third upper top plate 34.

[0038] The specific description of the above structure is as follows: the water pump 33 is used to draw the fruit juice inside the storage tank 376 into the liquid outlet 39.

[0039] The separation assembly 37 includes a storage tank 376 fixedly connected to the upper side of the third upper top plate 34. A cover plate 371 is hinged to the upper side of the storage tank 376. A connecting plate 372 is fixedly connected inside the storage tank 376. A vibrating cylinder 373 is fixedly connected to one side of the connecting plate 372. A plurality of first filter holes 374 are evenly fixedly connected to the outer side and the lower side of the vibrating cylinder 373. A conveying bend 375 is fixedly connected to the lower side of the vibrating cylinder 373, and the other end of the conveying bend 375 passes through the storage tank 376. An ejection assembly 377 is provided at the lower end of both the conveying bend 375 and the liquid outlet head 39. A second hose 36 is fixedly connected to the input end of the water pump 33, and the other end of the second hose 36 is fixedly connected to the storage tank 376.

[0040] The specific explanation of the above structure is as follows: The storage tank 376 is used to store fruit juice. When the pressed juice is delivered, it is poured into the vibrating cylinder 373. The vibrating cylinder 373 is equipped with a vibration motor. When the juice is poured into the vibrating cylinder 373, the juice flows out through the first filter hole 374 and then into the storage tank 376. The remaining fruit particles are blocked by the first filter hole 374 and remain inside the vibrating cylinder 373, thus completing the separation of fruit juice and pulp.

[0041] A number of second filter holes 3751 are evenly provided on the lower side of one end of the conveying bend 375. A micro motor 3752 is fixedly connected to the outer side of the other end of the conveying bend 375. A drive shaft 3754 is fixedly connected to the output end of the micro motor 3752 and the drive shaft 3754 is rotatably connected to the conveying bend 375. Four semi-circular arc plates 3753 are evenly fixedly connected to the outer side of the drive shaft 3754.

[0042] The specific explanation based on the above structure is as follows: When a small portion of the fruit juice flows into the conveying bend 375, the remaining small portion of the fruit juice will flow into the interior of the storage tank 376 through the second filter hole 3751. When it is necessary to convey fruit pieces, the micro motor 3752 is started. The output end of the micro motor 3752 rotates, driving the transmission shaft 3754 to rotate, thereby driving the four semi-circular arc plates 3753 to rotate, causing the fruit pieces inside the conveying bend 375 to flow. In order to prevent some fruit pieces from accumulating in the corners inside the vibrating cylinder 373 and failing to fall into the interior of the conveying bend 375, the vibrating cylinder 373 is started to vibrate and displace the fruit pieces inside when conveying fruit pieces.

[0043] The injection assembly 377 includes a guide cylinder 3771 fixedly connected to the lower side of the delivery bend 375. The lower side of the guide cylinder 3771 is provided with a relief groove 3772. A pressure sensor 3773 is fixedly connected inside the relief groove 3772. A spring 3774 is provided below the pressure sensor 3773. The upper end of the spring 3774 is fixedly connected to the detection end of the pressure sensor 3773. A conical block 3776 is fixedly connected to the lower end of the spring 3774. The conical block 3776 has an inner conical surface 3778 inside and an outer conical surface 3777 outside. A slide tube 3775 is fixedly connected inside the conical block 3776, and the other end is slidably connected to the inside of the guide cylinder 3771. A semi-circular cotton strip 3779 is fixedly connected to the lower side of the conical block 3776.

[0044] The specific explanation of the above structure is as follows: both fruit juice and fruit particles are injected into the bottle through the injection component 377. The electric turntable 2 rotates to transport each bottle to different areas for filling, capping, and locking. Since juice bottles are usually divided into multiple sizes, and the height of each size of juice bottle is different, it is necessary to manually adjust the height of the filling head when filling juice bottles of different heights, which affects the subsequent filling speed and reduces the filling efficiency.

[0045] Therefore, when juice bottles of different heights are rotated by the electric turntable 2 and are about to move below the dispensing head 39, the bottle mouth first touches the outer conical surface 3777 of the conical block 3776. Since the slide tube 3775 is slidably connected to the guide tube 3771, when the bottle mouth of the juice bottle presses against the outer conical surface 3777 of the conical block 3776, the conical block 3776 is driven upward through the slide tube 3775, and the spring 3774 is gradually compressed. The pressure sensor 3773 detects the pressure value of the spring 3774 on it in real time, determines the range of its pressure value, and thus determines the height of the juice bottle. When the juice bottle mouth is level with the bottom of the conical block 3776, the spring 3774 is no longer compressed, and the juice bottle mouth slides into the conical block. When the inner conical surface 3778 of the 3776 is pressed against the bottle mouth by the spring 3774, the juice bottle is rotated again by the electric turntable 2. The bottle mouth begins to press the inner conical surface 3778 of the conical block 3776. The conical block 3776 is moved upward by the slide tube 3775. The spring 3774 is gradually squeezed until the bottle mouth is pressed against the semi-circular cotton strip 3779. The residual juice on the surface is wiped clean. Finally, it slides out of the inner conical surface 3778 of the conical block 3776 and is sent to the next station for positioning. The spring 3774 rebounds and drives the conical block 3776 back to its original position.

[0046] The higher the juice bottle, the more the spring 3774 is compressed, and the greater the pressure value detected by the pressure sensor 3773. Conversely, the lower the juice bottle, the less the spring 3774 is compressed, and the smaller the pressure value detected by the pressure sensor 3773. Based on the real-time pressure value detected by the pressure sensor 3773, the height of the juice bottle is determined, and the required amount of irrigation is calculated. This allows for the accurate injection of the appropriate amount of juice and fruit into the juice bottle.

[0047] The positioning mechanism 4 includes a support column 46 fixedly connected to the upper side of the worktable 1. A first cylinder 41 is fixedly connected to the outer side of the support column 46. A first cylinder 41 is fixedly connected to the upper side of the first cylinder 41, and the output end of the first cylinder 41 passes through the first fixed platform 43 and is fixedly connected to a top column 42. Two second fixed platforms 48 are provided on the lower side of the first fixed platform 43. One of the second fixed platforms 48 is fixedly connected to the support column 46. A U-shaped plate 47 is fixedly connected to the upper side of the two second fixed platforms 48. A second cylinder 44 is fixedly connected to the upper side of each U-shaped plate 47. A first clamping plate 45 is fixedly connected to the output end of the second cylinder 44.

[0048] The specific explanation of the above structure is as follows: the extension and retraction of the output end of the first cylinder 41 is used to drive the top column 42 to move up and down, thereby pressing down and positioning the juice bottle. Each first clamping plate 45 has a cleaning cotton on one side. The extension and retraction of the output end of the second cylinder 44 is used to drive the cleaning cotton to move, thereby approaching the threads of the juice bottle mouth, thereby wiping away the liquid remaining on the threads of the juice bottle mouth.

[0049] The upper cover mechanism 5 includes a second support frame 51. A vibratory feeder 52 is fixedly connected to the upper side of the second support frame 51. A conveyor table 53 is fixedly connected to the discharge end of the vibratory feeder 52. A fixed rod 543 is fixedly connected to the upper side of the conveyor table 53. A first upper top plate 541 is fixedly connected to the upper end of the fixed rod 543. A support plate 542 is fixedly connected to the outer side of the fixed rod 543.

A sliding column 553 is fixedly connected to the lower side of the second upper top plate 551 and is slidably connected to the first fixed block 552. A first sliding plate 56 is fixedly connected to the lower side of the sliding column 553. A suction cup 57 is fixedly connected to the lower side of the first sliding plate 56.

[0050] The specific description of the above structure is as follows: the vibrating plate 52 is used to transfer the bottle cap to the top of the conveyor table 53 by vibration, and then the conveyor table 53 transports it to the bottom of the suction cup 57. The suction cup 57 is a pneumatic suction cup used to hold the bottle cap. The extension and retraction of the output end of the third cylinder 54 is used to drive the first fixed block 552 to move back and forth, thereby bringing the suction cup 57 to the top of the bottle cap or the mouth of the juice bottle. The extension and retraction of the output end of the fourth cylinder 55 is used to drive the second upper top plate 551 to move up and down, thereby driving the suction cup 57 to move up and down, and then driving the bottle cap held by the suction cup 57 to move up and down, placing it on top of the juice bottle.

[0051] The locking mechanism 7 includes a first support frame 71 fixedly connected to the upper side of the workbench 1. A second hydraulic cylinder 79 and a guide rod 75 are fixedly connected inside the first support frame 71. A second slide plate 78 is fixedly connected to the output end of the second hydraulic cylinder 79. A first fixing plate 77 is fixedly connected to the upper side of the second slide plate 78. The first fixing plate 77, the second slide plate 78 and the guide rod 75 are slidably connected. A servo motor 76 is fixedly connected to the upper side of the first fixing plate 77. The output end of the servo motor 76 passes through the first fixing plate 77 and is fixedly connected to a first electric gripper 74. Two first hydraulic cylinders 72 are provided on the lower side of the first electric gripper 74. The first hydraulic cylinders 72 are fixedly connected to the first support frame 71 and their output ends are fixedly connected to a second clamping plate 73.

[0052] The specific explanation based on the above structure is as follows: the extension and retraction of the output end of the second hydraulic cylinder 79 is used to drive the first fixed plate 77 to move up and down, thereby driving the first electric gripper 74 and the servo motor 76 to move up and down, and then driving the first electric gripper 74 to move closer to or away from the bottle cap. The first electric gripper 74 is used to clamp the bottle cap. The rotation of the output end of the servo motor 76 is used to drive the first electric gripper 74 to rotate, thereby driving the bottle cap to rotate and screw it into the mouth of the juice bottle. The extension of the output end of the first hydraulic cylinder 72 is used to drive the second clamping plate 73 to press down on the juice bottle and prevent it from rotating when the bottle cap is locked.

[0053] The bottle feeding mechanism 8 includes a conveyor 81 fixedly connected to the upper side of the workbench 1. A third support frame 86 is provided on the upper side of the conveyor 81.

A fourth hydraulic cylinder 85 is fixedly connected to the upper side of the second fixing block 84. The output end of the fourth hydraulic cylinder 85 passes through the second fixing block 84 and is fixedly connected to the second fixing plate 83. Two second electric grippers 82 are fixedly connected to the lower side of the second fixing plate 83.

[0054] The specific explanation of the above structure is as follows: After the juice bottle is filled and the cap is locked, the output end of the third hydraulic cylinder 87 extends and the output end of the fourth hydraulic cylinder 85 extends, bringing the second electric gripper 82 close to the juice bottle. The second electric gripper 82 clamps the juice bottle, the output end of the third hydraulic cylinder 87 retracts, and the output end of the fourth hydraulic cylinder 85 extends, thereby placing the juice bottle above the conveyor 81 for transmission.
