Description

A filling valve stem and a filling valve Technical Field

[0001] This invention relates to the field of filling valve technology, specifically to a filling valve stem and a filling valve. Background Technology

[0002] Beverage filling is a core process in the liquid food production and processing. As the core actuator of beverage filling equipment, the filling valve's performance directly determines the metering accuracy, production efficiency, and product cleanliness. It is widely applicable to the large-scale automated filling production of various liquid beverages, including bottled drinking water, carbonated drinks, and fruit and vegetable juices. With the beverage industry's continuously increasing demands for food safety production control standards, production energy efficiency, and ease of equipment maintenance, the industry has also placed more stringent requirements on the filling valve's synchronization of action, anti-drip performance, structural rationality, and ease of maintenance.

[0003] Existing filling valves for beverage bottling, while equipped with residual beverage collection structures and corresponding drive control components, often use independent drive elements to control the reciprocating movement of the collection structure. This not only increases the overall structural complexity and control logic difficulty of the equipment but also easily leads to timing mismatches between the collection structure and the valve's lifting and lowering movements, causing action delays and affecting the operational efficiency and stability of the filling process. Furthermore, during the reciprocating movement of the collection structure, trajectory deviations and operational jams are prone to occur, making it difficult to reliably and accurately collect residual beverage dripping from the outlet port after filling. This can easily cause beverage dripping to contaminate the packaging bottle, filling station, and production environment, making it difficult to reliably ensure the cleanliness of the filling operation. While existing residual material collection structures in filling valves have a material temporary storage function, they struggle to reliably suck, transfer, and centrally collect the temporarily stored residual beverage, easily leading to material accumulation and overflow. This prevents effective recycling of residual beverage, increases material loss during production, and the suction structure cannot flexibly adjust operating parameters according to the amount of residual material under different filling conditions, making it difficult to adapt to diverse production needs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a filling valve stem and a filling valve to solve the technical problem of being unable to reliably and accurately collect residual beverage dripping from the outlet port after filling, which easily causes beverage dripping and contamination of the packaging bottle, filling station, and production environment, making it difficult to reliably ensure the cleanliness of the filling operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a filling valve stem, comprising a valve arm and a sealing body, wherein the sealing body is fixedly disposed at the bottom of the valve arm, and is used to precisely control the opening and closing of the valve body outlet with the lifting and lowering movement of the valve arm, thereby realizing precise opening and closing control of the filling material and ensuring the accuracy of filling metering. The valve arm comprises a driving main arm, a diaphragm and a secondary rod. The diaphragm is fixedly sleeved on the outside of the driving main arm, and is used to achieve dynamic sealing between the valve arm and the valve body cavity, preventing the filling material from leaking from the valve stem mating point, ensuring the sealing performance of the valve body cavity, and preventing material leakage that would cause waste and pollution. The upper end of the secondary rod and the lower end of the driving main arm are connected by a snap-fit ​​component consisting of a snap-fit ​​groove and a snap-fit ​​spring. The driving main arm is used to receive external driving force to drive the valve arm to move up and down. The snap-fit ​​connection structure facilitates the quick disassembly, assembly, maintenance and replacement of the valve stem, reducing the maintenance difficulty and downtime of the equipment.

[0006] Preferably, a collection box is provided at the bottom of the outlet end of the second one-way valve, and a sealing gasket is provided between the collection box and the second one-way valve. This is used to centrally store residual filling material discharged through the second one-way valve, realizing centralized recycling and reuse of materials and reducing material waste in the production process. The sealing gasket ensures the sealing of the connection between the second one-way valve and the collection box, preventing liquid leakage and air ingress, ensuring the airtightness of the drainage and storage process, and preventing secondary contamination of the recycled materials.

[0007] A filling valve, applied to the aforementioned filling valve stem, includes: a valve body and a water outlet port. The water outlet port is located at the outlet of the valve body, serving as the output port for filling materials. It can precisely connect to the bottle mouth of the packaging bottle below as the valve body moves up and down, completing the material filling operation. The valve arm is located in the inner cavity of the valve body, and a sealing element is provided between the sealing body and the inner wall of the outlet of the valve body. This ensures that the valve arm can move stably up and down within the inner cavity of the valve body. At the same time, the sealing element further enhances the sealing effect of the sealing body in the closed state, significantly reducing the risk of material leakage when the valve body is closed, and further ensuring the accuracy and cleanliness of the filling operation.

[0008] The valve arm is located within the inner cavity of the valve body, and a sealing element is provided between the sealing body and the valve body. First lifting components are provided on both outer sides of the valve body. The fixed end of the first lifting component is fixedly connected to the external frame, and the movable end is fixedly connected to the outer wall of the valve body. This provides a stable connection between the valve body and the external frame, and also provides the driving power for vertical lifting of the valve body. The descent and return movements of the valve body can be precisely controlled according to the start and stop of the filling process, matching the filling sequence of the packaging bottles. A collection mechanism is provided on the outside of the valve body to collect residual material dripping from the outer wall and port of the outlet after the filling operation, preventing residual material from contaminating the packaging bottles. The system is designed to ensure the cleanliness of the filling process, including the valve body, filling station, and production environment. The collection mechanism includes a collection bin, which serves as a receiving and temporary storage container for residual materials. It can synchronously switch positions with the valve body's lifting and lowering movements. During filling, it moves horizontally to expose the filling path at the water outlet. After filling, it returns horizontally to directly below the water outlet to collect dripping materials. The collection bin has a horizontal groove on its exterior to provide sliding limit space for the guide arm, constraining its movement trajectory and ensuring stability during the return movement of the collection bin, preventing movement deviation and jamming. The guide arm is slidably connected to the inner cavity of the horizontal groove, and the two sides of the guide arm... Each end is fixedly connected to a push rod, which transmits the rotational force of the first and second drive arms, driving the guide arm to slide along the transverse groove, thereby pulling the collection bin to complete the horizontal reciprocating motion. The other ends of the two sets of push rods are respectively rotatably connected to the lower end of the first drive arm and the upper end of the second drive arm. The first and second drive arms, push rods, and guide arms cooperate to form a linkage crank structure, which can convert the vertical lifting motion of the valve body into the horizontal reciprocating motion of the collection bin. There is no need to configure an additional independent drive element for the collection bin, realizing complete synchronization and linkage between the action of the collection bin and the valve body, greatly simplifying the equipment structure and control logic. The lower end of the second drive arm is rotatably connected to The device has a support base, providing a stable rotational support fulcrum for the second drive arm. It can also be fixedly connected to an external frame, providing a solid installation foundation for the entire linkage structure and ensuring structural stability during operation. The upper end of the first drive arm is externally rotatably connected to the valve body, directly receiving the displacement power generated during the valve body's lifting and lowering process, driving the linkage structure to operate synchronously: When the valve body descends for filling, the upper end of the first drive arm descends synchronously with the valve body, causing the first and second drive arms to swing synchronously. Through a push rod, the guide arm slides along the transverse groove, pulling the collection chamber horizontally away, fully exposing the filling path at the outlet port. When the valve body returns to its original position after filling, the upper end of the first drive arm rises synchronously with the valve body, causing the linkage structure to swing in the opposite direction, pulling the collection chamber horizontally back to directly below the outlet port to collect dripping liquid. The timing of the actions perfectly matches the filling process, with no additional action delay.

[0009] A storage mechanism is provided between the collection chamber and the support base for sucking, transferring, and collecting residual materials temporarily stored in the collection chamber, preventing residual materials from accumulating and overflowing. This also enables the recycling of filling materials, reducing material loss during production. The storage mechanism includes an air box, the outer wall of which is fixedly connected to the outer wall of the collection chamber. This air box serves as the power chamber for sucking and discharging materials, sliding horizontally synchronously with the movement of the collection chamber. Its internal volume changes through its displacement relative to the piston, creating the power conditions for negative pressure suction and positive pressure discharge. The inlet of the air box is connected to a first one-way valve to control the unidirectional flow of materials, allowing only materials from the collection chamber to flow into the air box cavity, preventing materials from flowing back into the collection chamber, ensuring the effectiveness of the suction action. The inlet of the valve is connected to the outlet of the collection chamber. The outlet of the air box is connected to a second one-way valve to control the one-way discharge of materials, allowing only the materials inside the air box to be discharged outwards, preventing external materials or air from flowing back into the air box, and ensuring the stability and controllability of the discharge action. A piston is slidably connected to the inner cavity of the air box. The outer wall of the piston is sealed to the inner wall of the air box, forming a variable-volume sealed cavity. When the air box slides along the outside of the piston, it cooperates to realize the pressure change inside the cavity, providing the core power for the suction and discharge of materials. The piston rod end is connected to a second lifting component to drive the piston to adjust its horizontal position. The initial position of the piston can be adjusted according to the amount of residual material under the filling conditions, thereby changing the effective suction volume of the air box to adapt to different production needs.

[0010] Preferably, the top of the support base is provided with a water outlet groove, and the outside of the support base is provided with assembly holes. The water outlet groove can be used to guide the smooth flow of discharged residual materials, avoiding the accumulation of materials on the surface of the support base and the growth of bacteria. The assembly holes are used to stably assemble and fix the support base to the external frame, further enhancing the installation stability of the entire device and ensuring the positional accuracy of each component during operation.

[0011] Preferably, the inner cavity of the transverse groove is provided with a wear-resistant pad, and the end of the guide arm that contacts the transverse groove is provided with a wear-resistant layer. This can significantly reduce the wear of the components during the high-frequency reciprocating sliding process of the guide arm in the transverse groove, extend the service life of the components, and at the same time ensure the accuracy of the sliding fit in the long term, avoid the displacement deviation of the collection chamber due to component wear, and ensure the accuracy of the liquid receiving action.

[0012] Preferably, the top opening of the collection chamber is fully covered with a hydrophobic film, and a sealing sleeve is provided at the junction of the collection chamber and the gas box. The hydrophobic film allows dripping residual material to quickly flow into the inner cavity of the collection chamber, preventing material from adhering and lingering on the top of the collection chamber, and also preventing material from splashing and overflowing. The sealing sleeve ensures the airtightness of the connection between the collection chamber and the gas box, preventing air leakage and pressure loss during the suction process, ensuring the effectiveness of negative pressure suction, and preventing material leakage from contaminating the filling environment.

[0013] Preferably, a support plate is provided on the outside of the second lifting component, and the support plate is fixedly connected to the support base. A support arm is provided between the support plate and the support base. The support plate provides stable installation support for the second lifting component, ensuring the coaxiality of the second lifting component and the piston, avoiding uneven wear during piston movement, and ensuring the sealing accuracy of the piston and the inner cavity of the gas box. The support arm can further strengthen the connection strength between the support plate and the support base, improve the structural stability of the entire storage mechanism, and prevent the components from loosening or shifting during long-term reciprocating operation.

[0014] Preferably, the bottom of the inner cavity of the collection chamber is designed with a downward sloping surface towards the water outlet, and the outer walls of the push rod, the first drive arm, and the second drive arm are all provided with integrally formed reinforcing arms. The sloping design at the bottom of the inner cavity of the collection chamber can guide the collected residual material to converge towards the water outlet, making it easier for the first one-way valve to completely draw the material into the air box, avoiding the accumulation of material residue in the inner cavity of the collection chamber. The reinforcing arms can significantly improve the structural strength and deformation resistance of the push rod, the first drive arm, and the second drive arm, ensuring that the linkage structure will not deform during long-term high-frequency reciprocating operation, and ensuring the accuracy of motion transmission and structural stability.

[0015] Preferably, a control module is provided on the top of the support base, and the control terminal of the control module is electrically connected to the drive element of the first lifting component, the second lifting component, and the valve arm, respectively. It is used to centrally control the lifting and filling action of the valve body, the on / off control action of the valve arm, and the piston adjustment action of the second lifting component, so as to realize the automated coordinated operation of the filling process and the residual material recovery process. It can accurately match the action sequence of each component according to the filling rhythm, and improve the automation level and operational stability of the entire filling device.

[0016] Compared with existing technologies, this invention provides a filling valve stem and a filling valve, which have the following advantages: The filling valve stem and filling valve, through the linkage design of the valve body and the collecting mechanism, can synchronously drive the collecting chamber to complete the horizontal position switching by means of the lifting and lowering movement of the valve body. This eliminates the need for an additional independent driving component for the collecting chamber, significantly simplifying the equipment structure and control logic. Simultaneously, it ensures precise matching of the action sequence with the filling process, without additional action delays, thus improving the operating efficiency and stability of the filling operation. After filling, the collecting chamber can accurately return to directly below the water outlet port to collect dripping residual material, preventing material dripping from contaminating the packaging bottles, filling station, and production environment, ensuring the cleanliness of the filling operation. The sliding cooperation between the transverse groove and the guide arm can constrain the movement trajectory of the collecting chamber, preventing it from deviating or jamming, and ensuring the smoothness of its reciprocating movement.

[0017] The supporting storage mechanism can simultaneously suck, transfer and collect residual materials in the collection chamber, avoiding material accumulation and overflow in the collection chamber, while realizing the recycling of filling materials, reducing production losses. It can also adjust the initial position of the piston through the second lifting component to change the effective suction volume of the air box and adapt to the needs of different filling conditions.

[0018] The matching filling valve stem precisely controls the opening and closing of the valve body outlet, ensuring accurate filling and metering. The diaphragm structure provides a reliable dynamic seal between the valve arm and the valve body cavity, preventing material leakage. The snap-fit ​​connection between the main drive arm and the auxiliary rod facilitates quick disassembly, assembly, maintenance, and replacement of the valve stem, reducing equipment maintenance difficulty and downtime, and improving the continuity of equipment operation and ease of use.

When the valve body 1 returns to its original position after filling, it simultaneously drives the collection chamber 31 to reset below the water outlet port 11 to receive the dripping liquid. The timing of the action is completely matched with the filling process, and there is no additional action delay.

[0028] A storage mechanism 4 is provided between the collection chamber 31 and the support base 5. It is used to suck, transfer and collect the residual materials temporarily stored in the collection chamber 31, so as to avoid the accumulation and overflow of residual materials in the collection chamber 31. At the same time, it realizes the recycling of filling materials and reduces material loss in the production process. The storage mechanism 4 includes an air box 41, which serves as a power chamber for sucking and discharging materials. It can slide synchronously with the movement of the collection chamber 31. By changing the internal volume of the air box relative to the piston 45, it forms the power conditions for negative pressure suction and positive pressure discharge. The water inlet of the air box 41 is connected to a first one-way valve 42, which is used to control the one-way flow of materials. Only the materials in the collection chamber 31 are allowed to flow into the inner cavity of the air box 41, preventing the materials in the air box 41 from flowing back to the collection chamber 31, ensuring the effectiveness of the suction action.

[0034] The bottom of the inner cavity of the collection chamber 31 is designed with a slope, and reinforcing arms are provided on the outside of the push rod 34, the first drive arm 35, and the second drive arm 36. The slope design of the bottom of the inner cavity of the collection chamber 31 can guide the collected residual material to converge towards the outlet end, so that the first one-way valve 42 can completely draw the material into the air box 41, avoiding the accumulation of material in the inner cavity of the collection chamber 31.

It can accurately match the action sequence of each component according to the filling rhythm, and improve the automation level and operation stability of the entire filling device.

[0036] The working principle of this scheme is as follows: The fixed ends of the support base 5 and the first lifting component 12 are fixedly connected to the external frame, and the movable end of the first lifting component 12 is fixedly connected to the outer wall of the valve body 1, thus completing the overall assembly of the device. When the filling operation starts, the first lifting component 12 drives the valve body 1 to descend vertically, so that the water outlet 11 is precisely aligned with the bottle mouth of the packaging bottle below. At the same time as the valve body 1 descends, the upper end of the first driving arm 35 descends synchronously with the valve body 1, driving the first driving arm 35 and the second driving arm 36 to swing outward synchronously. Through the push rod 34, the guide arm 33 slides along the transverse groove 32, thereby pulling the collection chamber 31 to move horizontally outward, fully exposing the filling path of the water outlet 11. At this time, the valve arm 2 descends to open the water outlet of the valve body 1, and the filling operation begins. After the filling operation is completed, the valve arm 2 rises to close the water outlet of the valve body 1, and the first lifting component 12 drives the valve body 1 to rise vertically back to its original position. As the valve body 1 rises, the upper end of the first drive arm 35 moves upward synchronously with the valve body 1, causing the first drive arm 35 and the second drive arm 36 to swing inward synchronously. Through the push rod 34, the guide arm 33 slides in the opposite direction along the transverse groove 32, thereby pulling the collection chamber 31 to return to its horizontal position inward, precisely moving it to directly below the water outlet 11 to collect the residual liquid dripping from the water outlet 11. While the collection chamber 31 reciprocates horizontally, it causes the air box 41, which is fixedly connected to it, to slide horizontally along the piston 45. When the collection chamber 31 returns to its horizontal position inward, the air box 41 moves inward synchronously with the collection chamber 31, increasing the volume of the inner cavity of the air box 41 and creating a negative pressure. Through the first one-way valve 42, the residual liquid collected in the collection chamber 31 is drawn into the inner cavity of the air box 41. When the collection chamber 31 moves outward, the gas box 41 moves outward synchronously with the collection chamber 31. The volume of the inner cavity of the gas box 41 decreases, creating positive pressure. The liquid in the inner cavity of the gas box 41 is discharged into the collection box 44 through the second one-way valve 43 for centralized storage, thus completing the recovery of residual materials.
