Description

Technical Field

[0001] This utility model relates to the field of liquid filling equipment technology, and in particular to a device for accurately opening the filling valve to control the filling flow. 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 that controls the opening and closing of the filling valve. A heating sleeve is fitted on the outside of the valve body. 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, and the end of the plug rod extends to the valve port to close the valve body. 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

[0006] The technical problem to be solved by this utility model is to provide a device with a simple structure, low cost, and the ability to accurately control the filling flow of the filling valve.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to design a device for accurately opening the filling valve and controlling the filling flow: it includes a mounting plate 1, a driving power mechanism and a driving execution mechanism, wherein the driving power mechanism is vertically arranged on the upper part behind the mounting plate 1, and the driving execution mechanism is arranged on the lower part behind the driving power mechanism.

[0008] The driving power mechanism includes a servo motor 2 and an electric cylinder 3. The electric cylinder 3 is located on the upper part behind the mounting plate 1, and the servo motor 2 that drives the electric cylinder 3 is located on its upper part. The electric cylinder shaft that extends downward from the electric cylinder 3 is connected to the driving actuator.

[0009] The actuator includes an opening roller 5 and an opening roller mounting plate 4; the upper part of the opening roller mounting plate 4 is connected to the lower end of the electric cylinder shaft extending downward from the electric cylinder 3, and the opening roller 5 is mounted on the middle part of the front of the opening roller mounting plate 4.

[0010] It also includes a sliding single guide mechanism, which comprises a linear guide rail 8 and a linear guide rail transverse connecting plate 6; the mounting plate 1 is in the shape of a "Г" or The linear guide rail 8 is vertically mounted on the lower left or right side of the mounting plate 1; the left or right end of the front of the linear guide rail transverse connecting plate 6 is movably mounted on the linear guide rail 8; the lower end of the downward-extending electric cylinder shaft of the electric cylinder 3 is also connected to the upper side of the right or left end of the linear guide rail transverse connecting plate 6.

[0011] It also includes a sliding double guide mechanism, which includes a pair of linear guide rails 8 and a linear guide rail transverse connecting plate 6; the mounting plate 1 is in the shape of "Π", and the pair of linear guide rails 8 are vertically arranged on the "I" part on the lower left and right sides of the rear of the "Π" shaped mounting plate 1; the left and right ends of the front of the linear guide rail transverse connecting plate 6 are movably arranged on the pair of linear guide rails 8; the lower end of the electric cylinder shaft extending downward from the electric cylinder 3 is also connected to the upper middle part of the linear guide rail transverse connecting plate 6.

[0012] This invention relates to a device for precisely opening filling valves and controlling filling flow. A servo motor and an electric cylinder drive the opening roller to move up and down. Due to the extremely high precision of the servo motor and electric cylinder, the opening angle of the filling valve core can be precisely adjusted, thereby achieving precise control of the filling flow rate. Furthermore, only one opening device is needed to open multiple filling valves, resulting in a simple structure and relatively low cost. Attached Figure Description

[0026] Example 1:

[0027] The device for precisely opening the filling valve and controlling the filling flow rate in this embodiment consists of a mounting plate 1, a driving power mechanism, and a driving execution mechanism.

[0028] The driving power mechanism consists of a servo motor 2 and an electric cylinder 3. The electric cylinder 3 is located on the upper part behind the mounting plate 1, and the servo motor 2 is located on top of it and drives the electric cylinder 3. The downward-extending electric cylinder shaft of the electric cylinder 3 is connected to the driving actuator.

[0029] The actuator consists of an opening roller 5 and an opening roller mounting plate 4; the opening roller 5 consists of a roller body, a roller screw shaft extending from the roller body, and a roller nut (none are marked); the opening roller mounting plate 4 is bent (i.e., "Г" shaped, see appendix). Figure 2 and 5 (As shown); the upper part of the opening roller mounting plate 4 (i.e., the “I” part in the shape of “Г”) is connected to the lower end of the electric cylinder shaft that extends downward from the electric cylinder 3, and the roller screw shaft of the opening roller 5 is inserted from front to back into the middle part of the front of the opening roller mounting plate 4.

[0030] The device for precisely opening the filling valve and controlling the filling flow rate in this embodiment is used in conjunction with a filling valve whose valve handle is fan-shaped.

[0031] Before use, the device for accurately opening the filling valve and controlling the filling flow rate in this embodiment is first suspended under the fixed control panel, so that the opening roller 5 and the valve handle 9 of the filling valve (usually multiple filling valves are provided, which are composed of valve body 7, valve handle 9 and valve core shaft 10, and the valve handle 9 is fan-shaped) are on the same cylindrical surface, and the opening roller 5 is located above the valve handle 9.

[0032] During use, when the filling valve on the filling tray rotates to the position below the device for precisely opening the filling valve and controlling the filling flow rate in this embodiment, the opening roller 5 will collide with the upper right corner of the fan-shaped valve handle 9 of the filling valve. As the filling valve continues to rotate, it further pushes the valve handle 9, along with the valve core shaft 10 (and the valve core not shown in the figure), to rotate counterclockwise (see attached figure). Figure 1 As shown in the diagram, the filling valve moves from left to right, thus opening the valve core at a certain angle. Depending on the capacity of the container being filled, the servo motor 2 drives the electric cylinder 3 and its lower opening roller 5 to move vertically, achieving the required opening angle for different capacities. Because the servo motor 2 and the electric cylinder 3 have high operational precision, the opening angle is very accurate each time, thus precisely controlling the filling flow rate of the filling valve.

[0033] 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 a timely manner, so that the device for accurately opening the filling valve and filling the flow rate in this embodiment will drive the electric cylinder 3 via the servo motor 2 to lift the lower end of the opening roller 5 before it rotates to the lower part of the opening roller 5 at this station, so that it does not contact the valve handle 9, and thus does not open the filling valve, thereby realizing the function of no filling without bottles.

[0034] Example 2:

[0035] The device for precisely opening the filling valve and controlling the 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 8 and a transverse connecting plate 6. The mounting plate 1 is in the shape of a "Г" or... The linear guide 8 is vertically mounted on the lower left or right side of the mounting plate 1. A hole (not marked in the attached figure) is provided in the middle of the right or left side of the linear guide transverse connecting plate 6 to accommodate the roller screw shaft and roller nut of the opening roller 5. The left or right end of the front of the linear guide transverse connecting plate 6 is mounted on the linear guide 8 and can be moved up and down. The lower end of the electric cylinder shaft extending downward from the electric cylinder 3 is also connected to the upper side of the right or left end of the linear guide transverse connecting plate 6.

[0036] During use, when the electric cylinder 3 pushes the lower actuator, the left or right end of the linear guide rail transverse connecting plate 6 can move up and down along the linear guide rail 8. This effectively resists the impact force generated when the opening roller 5 collides with the valve handle 9, enhances the rigidity of the electric cylinder shaft, and protects the electric cylinder 3, thereby ensuring the accuracy of movement.

[0037] Everything else is basically the same as in Example 1, and will not be repeated here.

[0038] Example 3:

[0039] The device for precisely opening the filling valve and controlling the filling flow rate in this embodiment is an improvement on Embodiment 1. The difference between Embodiment 1 and Embodiment 1 is that a sliding double guide mechanism is also provided. This sliding double guide mechanism consists of a pair of linear guide rails 8 and a linear guide rail transverse connecting plate 6. The mounting plate 1 is in the shape of a "Π". The pair of linear guide rails 8 are vertically arranged on the "I" part on the lower left and right sides of the rear of the "Π" shaped mounting plate 1. In the middle of the linear guide rail transverse connecting plate 6, a hole is provided to accommodate the roller screw shaft and roller nut of the opening roller 5 (not marked in the figure). The left and right ends of the front of the linear guide rail transverse connecting plate 6 are movably arranged on the pair of linear guide rails 8. The lower end of the electric cylinder shaft extending downward from the electric cylinder 3 is also connected to the upper middle part of the linear guide rail transverse connecting plate 6.

[0040] During use, when the electric cylinder 3 pushes the lower actuator, the left or right end of the linear guide rail transverse connecting plate 6 can move up and down along the linear guide rail 8. This effectively resists the impact force generated when the opening roller 5 collides with the valve handle 9, enhances the rigidity of the electric cylinder shaft, and protects the electric cylinder 3, thereby ensuring the accuracy of movement.

[0041] Everything else is basically the same as in Example 1, and will not be repeated here.

[0042] This utility model relates to a device for precisely opening a filling valve to control the filling flow rate. It is used in conjunction with a filling valve whose valve handle is fan-shaped and can be used for high-speed rotary liquid filling.
