Description

Technical Field

[0001] This utility model relates to the field of liquid filling equipment technology, and in particular to a filling device for precisely controlling the filling flow rate. Background Technology

[0002] In existing technologies, flow control during high-speed liquid filling processes requires opening the filling valve at the start of a filling cycle and resetting it at the end of the cycle. Currently, most filling valve opening devices use a one-to-one mechanism, resulting in a bulky and complex structure and increased costs. Moreover, these opening devices mostly use cylinders, and due to the low precision of cylinder shaft extension, it is difficult to achieve accurate flow control.

[0003] Chinese Patent (Patent Application No. 2014800563480) discloses a "Method and Filling Valve System for a Filling Valve," which is configured to discharge a predetermined volume of liquid product into a single package (130). The system includes at least one filling valve (110, 210); a controller (150) configured to open the at least one filling valve (110, 210) to allow the liquid product to be discharged, and configured to close the at least one filling valve (110, 210); and a flow meter (140, 240) configured to measure the amount of liquid product discharged through the at least one filling valve (110, 210). The system (100, 200) further includes pressure sensors (125, 225) configured to measure the pressure upstream of the at least one filling valve (110, 210), wherein the controller (150) is further configured to calculate an estimated discharge volume during a shutdown procedure of the at least one filling valve (110, 210) based on the measured pressure, and to initiate the shutdown procedure based on the estimated discharge volume.

[0004] Another Chinese patent (patent application number 2021202945491) discloses a "filling valve and filling device", which includes a valve body with an inlet on the side wall of the valve body. The valve body is equipped with a plug rod to control the opening and closing of the filling valve. The valve body is fitted with a heating sleeve. One end of the valve body is provided with a valve port. During operation, when the plug rod is located above the inlet, the valve body opens. When the end of the plug rod extends to the valve port, the valve body is closed. This utility model also provides a filling device using the filling valve, including a filling valve that can operate synchronously and a bracket for installing the filling valve. The bracket is equipped with a power component and a buffer component. By combining with the filling valve in this utility model, automated filling can be achieved, which can effectively reduce dripping during the filling process and improve filling quality and filling efficiency.

[0005] Another Chinese patent (patent application number 2022228032342) discloses a "Multi-Volume Micro-Filling Valve Opening Device," which includes a bracket, multiple valves mounted on the bracket, and a drive unit mounted on the bracket and connected to the multiple valves. The drive unit includes a drive component, a rack, and multiple gears. The drive component is mounted on the bracket, the rack is connected to the drive component and driven by the drive component to perform linear motion, and the multiple gears mesh with the rack. Each valve is connected to a connecting shaft, which is connected to the gears. The gears drive the connecting shaft to rotate, thereby opening or closing the valve. This utility model connects multiple filling valves to the same power source, achieving synchronous filling, reducing the use of power sources, saving energy and reducing consumption. By utilizing the cooperation of gears and racks, it ensures the synchronicity and convenience of the filling valves, achieving automation and reducing costs. Summary of the Invention

[0018] This invention relates to a filling device for precisely controlling filling flow rate. It employs a filling valve with a fan-shaped handle, utilizing a servo motor-driven electric cylinder to move an opening roller that pushes the fan-shaped side of the valve handle. This causes the fan-shaped valve handle (along with the valve core) to rotate at a certain angle, thus opening the flow rate of the valve core (i.e., the filling flow rate). Coupled with a linear guide rail, the device can precisely move the opening roller, thereby precisely controlling the opening angle of the filling valve core and achieving precise filling. Furthermore, as it is a mechanical filling valve, its structure is simple, maintenance and operating costs are low, and it can achieve high-speed filling. Additionally, during use, the opening roller pushing the fan-shaped side can be immediately removed, preventing it from pushing the fan-shaped side, thus achieving the function of no-bottle-no-fill.

[0049] Example 1:

[0050] The filling device for precise control of filling flow rate in this embodiment consists of a filling valve opening mechanism 1, a fixed control disc 2, two or more filling valves 3, a rotating filling turntable 4, and a main shaft 5. The rotating filling turntable 4 is mounted on the main shaft 5 and rotates with the main shaft 5. The fixed control disc 2 is mounted on the main shaft 5 and does not rotate with the main shaft 5. The filling valve opening mechanism 1 is located around the fixed control disc 2 corresponding to the position where the filling valve 3 starts filling. Two or more filling valves 3 are evenly arranged around the rotating filling turntable 4.

[0051] The filling valve 3 consists of a valve body 8, a valve handle 7, and a valve core shaft 9. The valve handle 7 is fan-shaped. The valve body 8 is a ball valve with a valve core (not shown in the attached figure) inside its cavity. The inner end of the valve core shaft 9 is connected to the valve core, and its outer end passes radially through the middle of the valve body 8 and is then fitted with the valve handle 7.

[0052] The filling valve opening mechanism 1 consists of a filling valve opening mechanism mounting plate 12, a driving power component, and a driving execution component. The filling valve opening mechanism mounting plate 12 is set on the fixed control panel 2 around the filling valve 3 starting filling position. The driving power component is set behind the filling valve opening mechanism mounting plate 12, and its lower part is connected to the driving execution component.

[0053] The driving power assembly consists of a servo motor 10 and an electric cylinder 11. The electric cylinder 11 is located on the upper part behind the filling valve opening mechanism mounting plate 12. The servo motor 10 is located on the upper part of the electric cylinder 11 and drives the electric cylinder 11. The electric cylinder shaft 13 extending downward from the electric cylinder 11 is connected to the driving execution assembly.

[0054] The actuator assembly consists of an opening roller 15 and an opening roller mounting plate 14. The opening roller 15 consists of an opening roller body, an opening roller screw shaft extending from the opening roller body, and an opening roller nut (not marked in the attached drawings). The upper part of the opening roller mounting plate 14 is connected to the lower end of the electric cylinder shaft 13 extending downward from the electric cylinder 11. The opening roller screw shaft of the opening roller 15 is mounted from front to back in the middle of the front of the opening roller mounting plate 14.

[0055] The opening roller 15 of the actuator is placed on the upper part of the fan-shaped valve handle 7, and the opening roller 15 and the valve handle 7 are on the same cylindrical surface.

[0056] In use, when the filling valve 3 on the rotary filling turntable 4 rotates to the position below the filling valve opening mechanism 1, the opening roller 15 will collide with the upper sector angle of the sector-shaped valve handle 7 of the filling valve 3 (see appendix). Figure 14 As shown), with the continued rotation of filling valve 3 (i.e.: attached...), Figure 14 (As shown, moving from right to left), since the opening roller 15 remains stationary, it further pushes the valve handle 7, causing the valve core shaft 9 (along with the valve core, which is not shown in the attached diagram) to rotate clockwise, thereby opening the valve core by a certain angle. Depending on the capacity of the filling container, the servo motor 10 drives the electric cylinder 11 and its lower opening roller 15 to move up and down, achieving the required opening angle for different capacities. Because the servo motor 10 and the electric cylinder 11 have high operational precision, the opening angle is very accurate each time, thus precisely controlling the filling flow rate of the filling valve 3.

[0057] When the filling equipment detects that there are no bottles at a certain station, the control system of the filling equipment will issue an instruction in time to drive the electric cylinder 11 via the servo motor 10 to lift the lower end of the opening roller 15 before the opening roller 15 rotates to the lower part of the opening roller 15 at this station, so that it does not contact the fan-shaped valve handle 7 of the filling valve 3, and thus does not open the filling valve 3, thereby realizing the function of no filling without bottles.

[0058] Example 2:

[0059] The filling device for precise control of filling flow rate in this embodiment is an improvement on Embodiment 1. The difference between Embodiment 1 and Embodiment 1 is that it also includes a sliding single-guide mechanism, which is composed of a linear guide rail 17 and a transverse connecting plate 16 for the linear guide rail; the filling valve opening mechanism mounting plate 12 is in the shape of a "Г" or "". The linear guide 17 is vertically mounted on the lower left or right side of the "I" part behind the filling valve opening mechanism mounting plate 12; the left or right end of the front of the linear guide transverse connecting plate 16 is movably mounted on the linear guide 17; the lower end of the electric cylinder shaft 13 extending downward from the electric cylinder 11 is also connected to the right or left end of the upper side of the linear guide transverse connecting plate 16.

[0060] During use, when the electric cylinder 11 pushes the opening roller 15 at its lower part, the left or right end of the linear guide horizontal connecting plate 16 can move up and down along the linear guide 17. This can effectively resist the impact force generated when the opening roller 15 collides with the valve handle 7, enhance the rigidity of the electric cylinder shaft 13, and protect the electric cylinder 11, thereby ensuring the accuracy of movement.

[0061] Everything else is basically the same as in Example 1, and will not be repeated here.

[0062] Example 3:

[0063] The filling device for precisely controlling the filling flow rate in this embodiment is an improvement on Embodiment 1. The difference between this embodiment and Embodiment 1 is that a sliding double guide mechanism is also provided. This sliding double guide mechanism includes a pair of linear guide rails 17 and a linear guide rail transverse connecting plate 16. The filling valve opening mechanism mounting plate 12 is in the shape of a "Π". The pair of linear guide rails 17 are vertically arranged on the "I" part on the left and right sides of the lower middle part of the rear of the "Π" shaped filling valve opening mechanism mounting plate 12. The left and right ends of the front of the linear guide rail transverse connecting plate 16 are movably arranged on the pair of linear guide rails 17. The lower end of the electric cylinder shaft 13 extending downward from the electric cylinder 11 is also connected to the middle part of the upper side of the linear guide rail transverse connecting plate 16.

[0064] During use, when the electric cylinder 11 pushes the opening roller 15 at its lower part, the left or right end of the linear guide horizontal connecting plate 16 can move up and down along the linear guide 17. This can effectively resist the impact force generated when the opening roller 15 collides with the valve handle 7, enhance the rigidity of the electric cylinder shaft 13, and protect the electric cylinder 11, thereby ensuring the accuracy of movement.

[0065] Everything else is basically the same as in Example 1, and will not be repeated here.

[0066] Example 4:

[0067] The filling device for precise control of filling flow rate in this embodiment is an improvement on the first embodiment. The difference between the first and second embodiments is that a filling valve reset and closing mechanism 6 is also provided. The filling valve reset and closing mechanism 6 is composed of a reset and closing mechanism mounting plate 18, a reset push power component, and a reset push execution component.

[0068] The reset drive power assembly consists of a reset drive cylinder 19 and a reset drive cylinder shaft 20. The reset drive actuation assembly consists of a reset cam roller 24, a reset cam roller mounting plate 22, a pair of reset cam roller mounting pads 23, and a transverse connecting plate 25.

[0069] The reset closing mechanism mounting plate 18 is located around the fixed control panel 2 (specifically, the filling valve reset closing mechanism 6 is located on the fixed control panel 2 corresponding to the filling valve 3 at the end of filling). The reset push cylinder 19 is vertically positioned in the middle of the front of the reset closing mechanism mounting plate 18, and the lower end of its downwardly extending reset push cylinder shaft 20 is connected to the middle of the upper part of the horizontal connecting plate 25. The reset cam roller 24 consists of the reset cam roller body, the reset cam roller screw shaft extending from the reset cam roller body, and... The reset cam roller nut (not marked in the attached drawings) is used to form the reset cam roller 24. The reset cam roller screw shaft of the reset cam roller 24 is inserted from back to front and installed in the middle of the back of the reset cam roller mounting plate 22, and is fixed by the reset cam roller nut. The front of the reset cam roller mounting plate 22 is connected to the back of the transverse connecting plate 25 through a pair of reset cam roller mounting pads 23 arranged on the left and right. At the same time, the reset cam roller 24 is located at the lower part of the fan-shaped valve handle 7 of the filling valve 3, and the reset cam roller 24 and the valve handle 7 are on the same cylindrical surface.

[0070] It should be noted that during a 360-degree rotation, the filling valve 3 on the rotary filling turntable 4 begins filling immediately after the bottle to be filled enters from its lower part. Filling continues until completion, at which point the filling valve 3 stops filling, and the filled bottle is then discharged. Between the bottle discharge and bottle entry, the filling valve 3 does not fill. This results in two key positions: one is the position where filling begins after the bottle entry is completed, and the other is the position where filling stops after completion.

[0071] In use, when the filling valve 3 on the rotary filling turntable 4 rotates to the position of the filling valve reset closing mechanism 6, the reset cam roller 24 will collide with the lower sector angle of the sector-shaped valve handle 7 of the filling valve 3 (see appendix). Figure 15 As shown), with the continued rotation of filling valve 3 (i.e.: attached...), Figure 15 As shown in the diagram (moving from right to left), since the reset cam roller 24 is fixed, the reset cam roller 24 further pushes the valve handle 7, along with the valve core shaft 9 (and the valve core not shown in the attached diagram), to rotate counterclockwise, thereby closing the valve core.

[0072] When cleaning or disinfection is required, the reset cylinder 19 can be extended downwards. At this time, the lower end of the cylinder shaft 20 will push the transverse connecting plate 25 connected to it to move downwards, thereby moving the transverse connecting plate 25 and the reset cam roller 24 downwards, so that the reset cam roller 24 does not contact the valve handle 7, thereby realizing the cleaning or disinfection function.

[0073] Everything else is basically the same as in Example 1, and will not be repeated here.

[0074] Example 5:

[0075] The filling device for precise control of filling flow rate in this embodiment is an improvement on Embodiment 2. The difference between Embodiment 2 and Embodiment 2 is that it also includes a reset sliding single-guide mechanism, which is composed of a reset linear guide rail 26 and a transverse connecting plate 25; the reset closing mechanism mounting plate 18 is in the shape of a "Г" or "". The reset linear guide 26 is vertically mounted on the left or right side of the lower middle part of the reset closing mechanism mounting plate 18; the left or right end of the rear of the transverse connecting plate 25 is movably mounted on the reset linear guide 26; the lower end of the reset push cylinder shaft 20 is hinged to the connecting hinge seat 21 on the upper right or left end of the transverse connecting plate 25.

[0076] During use, when the reset push cylinder 19 pushes the reset push actuator at its lower part, the left or right end behind the transverse connecting plate 25 can move up and down along the reset linear guide rail 26. This can effectively resist the impact force generated when the reset cam roller 24 collides with the valve handle 7, enhance the rigidity of the reset push cylinder shaft 20, and ensure the accuracy of the movement direction.

[0077] The rest is basically the same as in Example 2, and will not be repeated here.

[0078] Example 6:

[0079] The filling device for precise control of filling flow rate in this embodiment is an improvement on embodiment 3. The difference between this embodiment and embodiment 3 is that: a reset sliding double guide mechanism is also provided, which is composed of a pair of reset linear guide rails 26 and a transverse connecting plate 25; the reset closing mechanism mounting plate 18 is in the shape of "Π", and the pair of reset linear guide rails 26 are vertically arranged on the "I" part on the lower left and right sides of the front middle part of the "Π" shaped reset closing mechanism mounting plate 18; the left and right ends of the rear of the transverse connecting plate 25 are movably arranged on the pair of reset linear guide rails 26; the lower end of the reset push cylinder shaft 20 is hinged to the connecting hinge seat 21 in the middle of the upper side of the transverse connecting plate 25.

[0080] During use, when the reset push cylinder 19 pushes the reset push actuator at its lower part, the left or right end behind the transverse connecting plate 25 can move up and down along the reset linear guide rail 26. This can effectively resist the impact force generated when the reset cam roller 24 collides with the valve handle 7, enhance the rigidity of the reset push cylinder shaft 20, and ensure the accuracy of the movement direction.

[0081] Everything else is basically the same as in Example 3, and will not be repeated here.

[0082] This invention relates to a filling device for precisely controlling the filling flow rate, which can be used for high-speed rotary liquid filling.
