DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection.

[0016] Example 1:

[0017] like Figure 1-Figure 3 As shown, the present invention provides a liquid material feeding device, including a main frame 1, on which a feed pump 2 and an air pressure pump 3 are fixedly installed. The main frame 1 is fixedly mounted with two feeding tanks 6 via a sub-frame 4. The feed pump 2 is connected to the feeding tank 6 via a feed conduit 7, on which a feed switching valve 8 is fixedly mounted. The air pressure pump 3 is connected to the top of the feeding tank 6 via an air intake conduit 9, on which an air intake switching valve 10 is fixedly mounted. The bottom of the feeding tank 6 is connected to a discharge conduit 11, on which a discharge switching valve 12 is fixedly mounted. An air pressure sensor 13 is fixedly mounted on the top of the feeding tank 6. A manual valve 14 is fixedly mounted at the end of the discharge conduit 11. A circuit control box 15 is fixedly mounted on the main frame 1. The feed switching valve 8, the air intake switching valve 10, and the discharge switching valve 12 are all electromagnetic control valves and are electrically connected to the circuit control box 15.

[0018] Through the above technical solution, the utility model is provided with two feeding tanks 6, and the feeding tanks 6 are alternately used to perform liquid material feeding operations by adjusting the switching valves. Specifically, when the equipment starts working, the feed switching valve 8 is adjusted by the controller to connect the first feeding tank 6 with the feeding conduit, and the feed pump 2 injects the liquid into the first feeding tank 6, and the injection amount is two-thirds of the volume of the feeding tank 6, and the remaining one-third of the volume is used to inject pressurized air. At this time, the controller adjusts the feed switching valve 8, the air intake switching valve 10 and the discharge switching valve 12, so that the second feeding tank 6 is connected to the feeding conduit, and the first feeding tank 6 is connected to the air intake conduit 9 and the discharge conduit 11. The air pressure pump 3 is started to inject air into the first feeding tank 6, and the air pressure pump 3 is turned on. The liquid material in the first loading tank 6 is discharged from the discharge pipe 11 through air pressure, and the feed pump 2 injects liquid material into the second loading tank 6. When the liquid material in the first loading tank 6 is transported, the controller adjusts the feed switching valve 8, the air intake switching valve 10 and the discharge switching valve 12, so that the first loading tank 6 is connected to the feed pipe, and the second loading tank 6 is connected to the air intake pipe 9 and the discharge pipe 11. The air pressure pump 3 starts to inject air into the second loading tank 6, and the liquid material in the second loading tank 6 is discharged from the discharge pipe 11 through air pressure. At the same time, the feed pump 2 injects liquid material into the first loading tank 6. This is repeated, and the continuous liquid feeding process is completed by switching the valves, thereby improving the working efficiency of liquid feeding.

[0019] Example 2:

[0020] like Figure 1-Figure 3 As shown, the main frame 1 of the present invention serves as the supporting structure for the entire device and is equipped with a feed pump 2 and an air pressure pump 3. The feed pump 2 is responsible for transporting liquid from an external source to the loading tank 6, while the air pressure pump 3 is used to generate air pressure and inject compressed air into the loading tank 6 through an air intake duct 9. Two loading tanks 6 are mounted on the main frame 1 via a sub-frame 4 to facilitate alternating use.

[0021] At the start of operation, the controller first adjusts the feed switching valve 8 to connect the first loading tank 6 to the feed pipeline. At this point, the feed pump 2 begins to operate, injecting liquid material into the first loading tank 6. The amount of liquid injected is two-thirds of the volume of loading tank 6, and the remaining one-third is used to inject pressurized air. This process ensures that the liquid material in loading tank 6 is completely filled and there is sufficient air space to apply pressure.

[0022] When the liquid material in the first loading tank 6 reaches a predetermined volume, the controller adjusts the feed switching valve 8, the air inlet switching valve 10, and the discharge switching valve 12, connecting the second loading tank 6 to the feed pipe and the first loading tank 6 to the air inlet conduit 9 and the discharge conduit 11. The air pump 3 then starts, injecting air into the first loading tank 6 through the air inlet conduit 9. This air pressure pushes the liquid material in the first loading tank 6, forcing it to be discharged from the discharge conduit 11, completing the loading process.

[0023] At the same time, the feed pump 2 injects liquid into the second loading tank 6, filling the second loading tank 6 for subsequent use. After the liquid in the first loading tank 6 is completely discharged under the action of air pressure, the controller adjusts the feed switching valve 8, the air inlet switching valve 10, and the discharge switching valve 12 to a new state. At this time, the first loading tank 6 will be connected to the feed pipe, and the second loading tank 6 will be connected to the air inlet conduit 9 and the discharge conduit 11. The air pressure pump 3 is started again to inject air into the second loading tank 6. Through similar air pressure, the liquid in the second loading tank 6 is pushed into the discharge conduit 11, completing the loading process.

[0024] During the liquid material delivery process, the controller continuously switches valve states to ensure that the liquid material can be circulated between the two loading tanks 6. Whenever the liquid material in the first loading tank 6 is completely discharged, the system automatically switches to the second loading tank 6 to ensure the continuity of the loading process. This circulation method enables continuous and stable production of liquid material, improving the efficiency of the production line.

[0025] The use of this automated liquid feeding device significantly reduces manual intervention in the production process and significantly improves production efficiency. Automatic liquid delivery not only ensures continuous feeding but also reduces production interruptions caused by improper operation. This device demonstrates excellent performance and reliability in industrial production, particularly when handling high-viscosity liquids, ensuring smooth production processes.

[0026] Each loading tank 6 of the present invention is equipped with an air pressure sensor 13. The main function of the air pressure sensor 13 is to monitor the air pressure level inside the loading tank 6 in real time and transmit the monitoring data to the controller. In this way, the controller can obtain the air pressure data inside the loading tank 6 and accurately control the operating status of the air pressure pump 3.

[0027] The air pressure sensor 13 is a precision measuring device that detects gas pressure in real time and converts it into an electronic signal. Installed on top of the loading tank 6, the air pressure sensor 13 continuously monitors changes in the air pressure within the tank, particularly during the injection and discharge of liquid material. The real-time data provided by the air pressure sensor 13 allows the controller to promptly monitor changes in the air pressure within the loading tank 6. This data is crucial for controlling the operation of the air pressure pump 3, as its operating status directly affects the efficiency and stability of liquid material delivery.

[0028] Specifically, when the air pressure inside loading tank 6 changes, the controller automatically adjusts the operating state of air pump 3 based on sensor feedback. For example, if the sensor detects that the air pressure is below a predetermined value, the controller instructs air pump 3 to increase the operating pressure to ensure smooth discharge of the liquid material. Conversely, if the air pressure is too high, the controller instructs air pump 3 to reduce the operating pressure to prevent damage to the equipment or affect the liquid material delivery effect.

[0029] In addition, the real-time data from the air pressure sensor 13 can help the controller optimize the entire loading process. During the liquid material delivery process, the flow of the liquid material is not only affected by the air pressure, but also by the operating status of the feed pump 2, the filling level of the loading tank 6, and other variables. By comprehensively analyzing the data provided by the air pressure sensor 13, the controller can more accurately adjust the operating status of each component to ensure stable delivery of the liquid material. For example, the controller can adjust the injection speed of the liquid material and the duty cycle of the air pressure pump 3 based on the air pressure data to maintain optimal working conditions and production efficiency.

[0030] The use of air pressure sensor 13 can also help detect equipment anomalies. If the sensor detects abnormal air pressure fluctuations, the controller can promptly issue an alarm and take appropriate measures, such as adjusting the operating status of air pressure pump 3 or suspending system operation for maintenance. This real-time monitoring and automatic adjustment function greatly improves the reliability and safety of the equipment and reduces production interruptions and losses caused by equipment failures.

[0031] The end of the discharge conduit 11 of the present invention is provided with a manual valve 14. The existence of the manual valve 14 is mainly to quickly stop the delivery of the liquid material during the liquid material loading process, which is particularly important when handling certain emergency situations or needing manual intervention.

[0032] The proper operation of the liquid loading device relies on the air pressure provided by the air pump 3 and the liquid delivery by the feed pump 2. The air pressure within the loading tank 6 plays a crucial role in the discharge of the liquid. However, in actual operation, the continuous air pressure within the loading tank 6 prevents the liquid from being immediately discontinued. In this situation, the manual valve 14 becomes particularly important.

[0033] Manual valve 14 is installed at the end of discharge conduit 11. The operator can manually operate the valve to directly control the flow of liquid material. When liquid material delivery needs to be immediately interrupted, whether due to system failure, operator error, or other emergency situation, the operator can simply manually close the valve to quickly terminate liquid discharge. This design provides a reliable means to ensure rapid response to various emergencies during liquid material delivery.

[0034] During the operation of the liquid feeding device, manual valve 14 effectively controls the liquid flow rate and stoppage time. By adjusting the valve's open / close status, the operator can precisely control the liquid delivery process, preventing excessive liquid delivery or equipment damage due to excessive air pressure or other factors. The provision of manual valve 14 allows for the flexibility of manual intervention in addition to automated control, enhancing operational safety and flexibility.

[0035] A circuit control box 15 is fixedly mounted on the main frame 1 of the present invention. This box serves as the control center for the entire device, managing and coordinating the operation of all electrical control components. Inside the box is a controller, the brain of the system, which controls the device's various valves and other electrical devices through electrical connections.

[0036] The controller in the circuit control box 15 is a complex electronic device that receives commands from sensors and the operating interface and, based on these commands, controls the operating states of the feed switching valve 8, the air inlet switching valve 10, and the discharge switching valve 12. These valves are electromagnetically controlled valves that open and close via electrical signals, ensuring precise control and automated operation of the liquid material loading process.

[0037] The feed switching valve 8, air inlet switching valve 10, and discharge switching valve 12 are key control components of the liquid material feeding system, directly impacting the flow of liquid and feeding efficiency. The solenoid control valves operate based on electromagnetic induction. Electric current excites the electromagnetic coil, generating a magnetic field that drives the valves open and close. A controller generates electrical signals to adjust the status of these valves, enabling precise management of the liquid material delivery process.

[0038] Specifically, the controller receives real-time data from the air pressure sensor 13 and other monitoring devices through electrical connections within the circuit control box 15, and adjusts the valve operating conditions accordingly. For example, when liquid material needs to be discharged from the first loading tank 6, the controller sends an electrical signal to open the feed switching valve 8 and the air inlet switching valve 10, while simultaneously closing other unnecessary valves to ensure smooth liquid discharge. Throughout the liquid material delivery process, the controller continuously adjusts the valve status based on real-time data to maintain optimal operating conditions.

[0039] The circuit control box 15 not only contains the controller, but also other electrical devices, such as a power management module, an interface module, and a communication module. These components ensure the stable operation of the controller and effective electrical connection with the rest of the system. The power management module is responsible for providing a stable power supply to the controller and solenoid valve, while the interface module ensures that the controller can exchange data and communicate with external devices. The communication module is used to transmit data to a host computer or remote monitoring system, enabling remote monitoring and management of the liquid material feeding device.

[0040] Through the coordinated operation of the circuit control box 15 and the controller, the entire liquid material feeding device can achieve automated and efficient operation. The controller's program automatically adjusts the operating status of each valve based on production needs and equipment status, thereby optimizing the liquid material delivery process, reducing manual intervention, and improving production efficiency. Furthermore, the circuit control box 15 also facilitates equipment fault detection and repair. By monitoring the various electrical signals in the circuit control box 15, operators can promptly identify and troubleshoot faults, ensuring the normal operation of the equipment.
