Description

Technical Field

[0001] This utility model relates to the field of liquid filling equipment technology, and in particular to a device for resetting and closing a filling valve. Background Technology

[0002] In existing technologies, during high-speed liquid filling, the filling valve needs to be closed at the end of a filling cycle and will only be reopened at the start of the next filling cycle. Currently, most filling valve closures use a one-to-one device, resulting in a bulky and complex structure and increased costs.

[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 simple structure, low cost and the ability to quickly close 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 resetting and closing a filling valve: it includes a mounting plate 1, a reset pushing power mechanism and a reset pushing execution mechanism. The reset pushing power mechanism is vertically arranged in the middle of the front of the mounting plate 1, and the reset pushing execution mechanism is arranged in the lower part of the reset pushing power mechanism.

[0008] The reset push power mechanism includes a reset push cylinder 2 and a reset push cylinder shaft 3. The reset push cylinder 2 is vertically arranged in the middle of the front of the mounting plate 1, and the lower end of the downward-extending reset push cylinder shaft 3 is connected to the reset push actuator.

[0009] The reset push actuator includes a reset cam roller 7, a reset cam roller mounting plate 5, a pair of reset cam roller mounting pads 6, and a transverse connecting plate 8. The reset cam roller 7 is located in the middle of the reset cam roller mounting plate 5. The front of the reset cam roller mounting plate 5 is connected to the rear of the transverse connecting plate 8 through the two reset cam roller mounting pads 6 on the left and right. The lower end of the reset push cylinder shaft 3 is connected to the upper middle part of the transverse connecting plate 8.

[0010] It also includes a reset sliding single guide mechanism, which comprises a linear guide rail 9 and a transverse connecting plate 8; the mounting plate 1 is in the form of... or The linear guide 9 is vertically positioned on the lower left or right side of the front of the mounting plate 1; the left or right end of the rear of the transverse connecting plate 8 is movably positioned on the linear guide 9; the lower end of the reset push cylinder shaft 3 is hinged to the connecting hinge seat 4 on the upper right or left side of the transverse connecting plate 8.

[0011] It also includes a reset sliding double guide mechanism, which includes a pair of linear guide rails 9 and a transverse connecting plate 8; the mounting plate 1 is in the shape of "Π", and the pair of linear guide rails 9 are vertically arranged on the "I" part on the lower left and right sides of the front of the "Π" shaped mounting plate 1; the left and right ends of the rear of the transverse connecting plate 8 are movably arranged on the pair of linear guide rails 9; the lower end of the reset push cylinder shaft 3 is hinged to the connecting hinge seat 4 in the middle of the upper side of the transverse connecting plate 8.

[0012] The device for resetting and closing the filling valve of this utility model uses a cylinder to push and pull the reset cam roller to move up and down, thereby pushing the filling valve with a fan-shaped valve handle to reset and close. Moreover, only one reset and closing device is used to achieve the reset and closing of multiple filling valves. Therefore, its structure is relatively simple and its cost is relatively low.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. The following description is by way of example, but the scope of protection of the present invention should not be limited thereto.

[0024] Example 1:

[0025] The device for resetting and closing the filling valve in this embodiment consists of a mounting plate 1, a reset driving power mechanism, and a reset driving execution mechanism.

[0026] The reset push power mechanism consists of a reset push cylinder 2 and a reset push cylinder shaft 3. The reset push cylinder 2 is vertically arranged in the middle of the front of the mounting plate 1, and the lower end of the downward-extending reset push cylinder shaft 3 is connected to the reset push actuator.

[0027] The reset actuator consists of a reset cam roller 7, a reset cam roller mounting plate 5, a pair of reset cam roller mounting pads 6, and a transverse connecting plate 8.

[0028] The reset cam roller 7 consists of a reset cam roller body, a reset cam roller screw shaft extending from the reset cam roller body, and a reset cam roller nut (not marked in the attached drawings). The reset cam roller screw shaft of the reset cam roller 7 is inserted from back to front into the middle of the reset cam roller mounting plate 5 and is fixed by the reset cam roller nut. In the middle of the transverse connecting plate 8, there is a hole (not marked in the attached drawings) to accommodate the reset cam roller screw shaft and the reset cam roller nut. The front of the reset cam roller mounting plate 5 is connected to the rear of the transverse connecting plate 8 through two reset cam roller mounting pads 6 on the left and right sides. The lower end of the reset push cylinder shaft 3 is connected to the upper middle part of the transverse connecting plate 8.

[0029] The device for resetting and closing the filling valve in this embodiment is used in conjunction with a filling valve whose valve handle is fan-shaped.

[0030] Before use, first suspend the device for resetting and closing the filling valve in this embodiment under the stationary control panel, so that the reset cam roller 7 is aligned with the filling valve (which consists of a valve body 10, a valve handle 12, and a valve core shaft 11, and the valve handle 12 is fan-shaped, see attached) located around the rotating filling disc. Figure 4 As shown, the valve handle 12 is on the same cylindrical surface, and the reset cam roller 7 is located at the lower part of the valve handle 12.

[0031] During use, when the filling valve on the filling tray rotates to the top of the reset cam roller 7 of the device for resetting and closing the filling valve in this embodiment (at this time, the filling at this station has been completed), the reset cam roller 7 will collide with the lower sector angle of the sector-shaped valve handle 12 of the filling valve, and as the filling valve continues to rotate, it will further push the valve handle 12 to rotate with the valve core shaft 11 (and the valve core not shown in the figure) to close the valve core.

[0032] When cleaning or disinfection is required, the reset cylinder 2 can be extended downwards. At this time, the lower end of the cylinder shaft 3 will push the horizontal connecting plate 8 connected to it to move downwards, thereby moving the reset cam roller mounting plate 5 and the reset cam roller 7 downwards, so that the reset cam roller 7 does not contact the valve handle 12, thus realizing the cleaning or disinfection function.

[0033] Example 2:

[0034] The device for resetting and closing the filling valve in this embodiment is an improvement on Embodiment 1. The difference between Embodiment 1 and Embodiment 1 is that a reset sliding single-guide mechanism is also provided. This reset sliding single-guide mechanism is composed of a linear guide rail 9 and a transverse connecting plate 8; the mounting plate 1 is... or The linear guide 9 is vertically mounted on the lower left or right side of the front 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 transverse connecting plate 8 to accommodate the reset cam roller screw shaft and the reset cam roller nut; the left or right end of the rear of the transverse connecting plate 8 is movably mounted on the linear guide 9; the lower end of the reset push cylinder shaft 3 is hinged to the connecting hinge seat 4 on the upper right or left side of the transverse connecting plate 8.

[0035] During use, when the reset push cylinder 2 pushes the reset push actuator at its lower part, the left or right end behind the transverse connecting plate 8 can move up and down along the linear guide rail 9. This can effectively resist the impact force generated when the reset cam roller 7 collides with the valve handle 12, enhance the rigidity of the reset push cylinder shaft 3, and ensure the accuracy of the movement direction.

[0036] Everything else is basically the same as in Example 1, and will not be repeated here.

[0037] Example 3:

[0038] The device for resetting and closing the filling valve in this embodiment is an improvement on embodiments 1 and 2. The difference between this device and embodiments 1 and 2 is that it also includes a reset sliding double guide mechanism, which is composed of a pair of linear guide rails 9 and a transverse connecting plate 8. The mounting plate 1 is shaped like a "Π", and the pair of linear guide rails 9 are vertically arranged on the "I" parts on the lower left and right sides of the front of the "Π" shaped mounting plate 1. In the middle of the transverse connecting plate 8, there is a hole (not marked in the figure) for accommodating the reset cam roller screw shaft and the reset cam roller nut. The left and right ends of the rear of the transverse connecting plate 8 are movably arranged on the pair of linear guide rails 9. The lower end of the reset push cylinder shaft 3 is hinged to the connecting hinge seat 4 in the middle of the upper side of the transverse connecting plate 8.

[0039] During use, when the reset push cylinder 2 pushes the reset push actuator at its lower part, the left and right ends behind the transverse connecting plate 8 can move up and down along the linear guide rail 9. This can effectively resist the impact force generated when the reset cam roller 7 collides with the valve handle 12, enhance the rigidity of the reset push cylinder shaft 3, and ensure the accuracy of the movement direction.

[0040] The rest is basically the same as in Examples 1 and 2, and will not be repeated here.

[0041] The device for resetting and closing the filling valve of this utility model is used in conjunction with a filling valve with a fan-shaped valve handle and can be used for high-speed rotary liquid filling.
