In the production and packaging process of sauce product, the supply of sauce is crucial. The traditional sauce supply mode mainly relies on manual operation or simple mechanical control, and there are many problems.
[0003] One of the key problems is the difficulty in achieving accurate control of the sauce level and automatic supply adjustment. In manual operation mode, the operator needs to frequently observe the sauce level and manually adjust the feed rate, which not only requires a lot of labor, but also cannot guarantee the stability and accuracy of sauce supply, and is prone to insufficient or excessive supply of sauce due to fluctuations in liquid level, thereby affecting production efficiency and product quality. In the simple mechanical control mode, although automation can be achieved to some extent, it often lacks real-time monitoring and feedback adjustment capability for the liquid level, and cannot flexibly adjust the sauce supply according to the actual situation, and cannot meet the needs of modern production.

[0035] Example 1
[0036] like Figure 1 As shown, an automatic controller for sauce product supply is used in a sauce product packaging production line. The sauce product packaging production line includes a sauce input device 4 and a packaging device 5. The automatic controller includes a liquid level sensor 1, a diaphragm pump 2, and a pipeline 3. The liquid level sensor 1 is fixedly installed on the input device 4 and is used to detect the sauce liquid level and output a sensor signal. The diaphragm pump 2 is connected to the liquid level sensor 1 via a circuit, receives the sensor signal emitted by the liquid level sensor 1, and changes its operating state according to the sensor signal. The pipeline 3 includes an inlet section 31 and an outlet section 32. One end of the inlet section 31 is connected to the input device 4, and the other end is connected to the input end of the diaphragm pump 2. One end of the outlet section 32 is connected to the output end of the diaphragm pump 2, and the other end leads to the packaging device 5.
[0037] In this embodiment, the liquid level sensor 1 specifically adopts a commercially available submersible hydrostatic liquid level sensor, model MAT-magnetostrictive liquid level gauge. Its probe 11 is cylindrical, made of corrosion-resistant stainless steel, with a diameter of 2 cm and a length of 5 cm, extending to a suitable depth inside the tank truck to accurately sense the sauce level. The liquid level sensor 1 is fixedly installed in a suitable position inside the mixing tank truck, accurately detecting the sauce level height and outputting a sensor signal. After acquiring the liquid level data, the liquid level sensor converts the detected liquid level information into an electrical signal output. The output signal is a standard 4-20mA current signal, which has strong anti-interference capabilities and a long transmission distance. Shielded twisted-pair cable is used on the output signal line, with the shielding layer grounded, effectively preventing external electromagnetic interference from affecting the signal. Simultaneously, an overvoltage protection device is also equipped on the signal line, which can promptly discharge overvoltage when the signal line is subjected to an unexpected high-voltage impact, protecting the sensor and subsequent circuitry. In addition, the liquid level sensor has a self-test function, which can periodically test its own circuit and probe 11. Once an abnormality is detected, it will immediately send an alarm signal through the fault alarm circuit to notify maintenance personnel to handle the situation.
[0038] In this embodiment, the diaphragm pump 2 is connected to the signal output terminal of the liquid level sensor 1 via a circuit, enabling it to sensitively receive the feedback signal (i.e., the sensor signal) and adjust its operating state accordingly. It starts operating when it receives a low liquid level feedback signal and stops operating when it receives a high liquid level feedback signal. The diaphragm pump is driven by a separate drive unit, which is a motor.
[0039] In this embodiment, the motor power is selected based on factors such as the sauce conveying requirements and pipeline resistance to ensure sufficient power. The motor has good starting and speed regulation performance, can reach rated speed in a short time, and can be adjusted according to actual needs to meet the sauce conveying requirements under different working conditions. The motor housing is made of cast iron, which has good heat dissipation performance, and the surface is painted to prevent rust. The motor is equipped with an overload protection device that automatically cuts off the power supply when the motor load is too large, protecting the motor from damage. Regarding the internal structure of the diaphragm pump, the pump body is made of metal, typically stainless steel, such as 304 stainless steel, which has good strength and corrosion resistance. The internal structure of the pump body is carefully designed, including the air inlet, air outlet, and diaphragm chamber. The size and shape of the air inlet and outlet are optimized to reduce fluid resistance and improve the pump's conveying efficiency. The size and shape of the diaphragm chamber are rationally designed to ensure sufficient space for the diaphragm to reciprocate and to effectively prevent sauce leakage.
[0040] In this embodiment, the diaphragm is made of a special rubber material, such as nitrile rubber. This rubber material has good flexibility and sealing properties, and can withstand certain pressure and deformation during the operation of the diaphragm pump, ensuring the sealed delivery of the sauce. The thickness of the diaphragm is rationally designed, generally between 2 and 3 millimeters, ensuring both the strength and elasticity of the diaphragm. The edges of the diaphragm are tightly connected to the pump body through a special sealing process to prevent sauce leakage. The electromagnetic drive device consists of components such as an electromagnetic coil and an armature. The electromagnetic coil is wound on an iron core. When energized, the iron core generates a magnetic field, attracting the armature to move, thereby driving the diaphragm to reciprocate. The number of turns and wire diameter of the electromagnetic coil are precisely calculated to ensure that the magnetic field strength generated is sufficient to drive the diaphragm. The armature is made of high-quality metal material, and its surface is hardened to improve its hardness and wear resistance.
[0041] In this embodiment, the pipeline 3 consists of two parts: an inlet section 31 and an outlet section 32. One end of the inlet section 31 is connected to the mixing tanker, and the other end is connected to the input end of the diaphragm pump 2. One end of the outlet section 32 is connected to the output end of the diaphragm pump 2, and the other end leads to the packaging equipment 5. The pipeline is made of food-grade plastic, such as polyvinylidene fluoride (PVDF). PVDF material has good corrosion resistance, high temperature resistance, and mechanical properties, and can withstand the corrosion of sauces and temperature changes within a certain range. The inner wall of the pipeline is smooth, with a roughness of less than Ra0.4, which reduces the resistance of the sauce during transportation and improves the transportation efficiency. At the same time, PVDF material has good hygiene properties, meets food hygiene standards, and will not contaminate the sauce. In terms of pipeline connections, the connections between the inlet section and the mixing tanker and the input end of the diaphragm pump, as well as the connections between the outlet section and the output end of the diaphragm pump and the packaging equipment 5, all adopt a well-sealed connection method to prevent sauce leakage. Furthermore, the surface of the pipeline has undergone special wear-resistant treatment to reduce surface damage caused by friction during installation and use. Metal reinforcing rings can also be installed on the pipeline, which are added at key parts of the feed section 31 and the discharge section 32 to prevent the pipeline from cracking or deforming during long-term use or when subjected to external impact.
[0042] In this embodiment, the input device 4 is not limited to a specific device; however, in this specific application scenario, it is a mixing tanker. This mixing tanker has the function of mixing sauces and can simultaneously input sauces into the target device, i.e., the packaging device 5. A mixing assembly 42 can be installed inside the mixing tanker. A drive motor 43 drives a transmission shaft assembly 41, thereby driving the mixing assembly 42 to perform circular motion around its axis to execute material mixing operations. A movable locking mechanism can also be installed at the bottom of the mixing tanker. In this embodiment, the movable locking mechanism is a self-locking universal wheel 44, enabling the mixing tanker to move freely within a preset working area. Furthermore, during operation, it can be securely fixed in a specific position using a dedicated fixing device, ensuring the stability and safety of the mixing operation. The mixing tanker is closely connected to the feeding section 31 and is used to transport sauces to the feeding section 31.
[0043] In this embodiment, the packaging equipment 5 is not limited to a specific device; however, in this specific application scenario, it is a vertical packaging machine, mainly used for automated packaging of sauce products. The vertical packaging machine includes a hopper 51 and a packaging machine body 52. The hopper 51 temporarily stores the sauce and guides it to the packaging machine body 52, while the packaging machine body 52 contains various mechanisms and devices for completing the packaging process. The hopper 51 of the vertical packaging machine is closely connected to the discharge section 32 and is used to collect the sauce delivered from the discharge port 32. The hopper 51 is fixedly positioned above the packaging machine body 52, ensuring that the sauce flows naturally into the packaging machine body 52 by gravity, preparing it for subsequent packaging processes.
[0044] In this embodiment, the bottom of the hopper 51 is funnel-shaped. This shape design can effectively collect the sauce, allowing it to flow centrally to the packaging machine body 52. Its inner wall is provided with guide ribs, which are evenly distributed along the circumference of the hopper 51 and extend obliquely downwards from the top. This structure guides the sauce smoothly into the packaging machine body 52, preventing the sauce from stagnating, accumulating, or flowing poorly within the hopper. This ensures the continuity and stability of the packaging process and prevents packaging efficiency and effectiveness from being affected by sauce supply issues.
[0045] In this embodiment, the packaging machine body 52 includes various key components that perform packaging actions. These components work together to complete the packaging task of the sauce. For example, there may be a metering device for precisely controlling the amount of sauce filled in each package; a heat-sealing device for heating and sealing the packaging material to ensure the airtightness of the packaging; and a cutting device for separating the packaged sauce from the continuous packaging material. The operation of these devices is uniformly coordinated by the control system, operating according to preset parameters and programs to ensure the quality and speed of packaging.
[0046] Working principle:
[0047] The level sensor 1 continuously and in real-time monitors the sauce level. During monitoring, a specific threshold is set. When the sauce level is detected to be higher than this threshold, the level sensor 1 sends a high-level signal. This high-level signal is received by the diaphragm pump 2, triggering its startup. The diaphragm pump 2 then pumps the sauce from the mixing tank to the packaging equipment 5 to meet the sauce requirements of subsequent production or packaging stages.
[0048] Conversely, when the level sensor 1 detects that the sauce level is below a set threshold, it will send a low level signal. This low level signal will also be received by the diaphragm pump 2, thereby triggering the diaphragm pump 2 to stop working.
[0049] The beneficial effects of this embodiment are as follows:
[0050] The automatic sauce supply controller provided in this embodiment achieves automated control of sauce supply through real-time monitoring of the sauce level by the level sensor 1 and precise automatic control of the working status of the diaphragm pump 2. This automation process significantly improves production efficiency and reduces the time and labor intensity caused by manual operation. At the same time, precise level monitoring and control ensure the continuity and stability of sauce supply, which helps to improve product quality.
[0051] Example 2
[0052] The difference between this embodiment and Embodiment 1 is that:
[0053] Liquid level sensor: While retaining the basic functions and structure of the liquid level sensor in Embodiment 1, a temperature compensation module is added. This module can monitor the temperature changes of the sauce in real time and feed the temperature signal back to the control circuit. The control circuit will correct the liquid level signal detected by the liquid level sensor according to a preset temperature-liquid level compensation algorithm to improve the accuracy of liquid level measurement, especially in production environments where the sauce temperature fluctuates significantly.
[0054] Diaphragm Pump: The diaphragm pump drive motor has been upgraded with a variable frequency speed control function, which can more precisely adjust the flow rate of the diaphragm pump according to production needs. At the same time, the drive motor is equipped with a fault self-diagnosis system, which can monitor the motor's operating parameters (such as current, voltage, temperature, etc.) in real time. When an abnormality is detected, the controller will promptly issue an alarm and can automatically adjust the operating mode or stop operation to prevent the fault from escalating further.
[0055] Piping: A buffer tank is added between the inlet and outlet sections of the pipeline. The buffer tank is equipped with a liquid level monitoring device and a safety valve. When the sauce supply in the inlet section is unstable, causing flow fluctuations, the buffer tank acts as a buffer, stabilizing the sauce flow in the outlet section and ensuring stable operation of the packaging equipment. The safety valve automatically opens to release pressure and ensure system safety when the pressure inside the buffer tank abnormally increases.
[0056] The working principle or operation process in this implementation is as follows:
[0057] Liquid Level Monitoring and Compensation: The liquid level sensor continuously monitors the sauce level in the mixing tank in real time, while the temperature compensation module simultaneously monitors the sauce temperature. When the detected liquid level is higher than a set threshold, the sensor amplifies and filters the signal, corrects the liquid level signal according to the temperature compensation algorithm, and then outputs a start signal; when the liquid level is lower than the set threshold, it outputs a stop signal. Simultaneously, the self-test module operates periodically, monitoring the sensor's own status in real time, and sends a fault alarm signal if any abnormality occurs.
[0058] Variable Frequency Drive and Pump Operation: The diaphragm pump is connected to a liquid level sensor via circuitry to receive its signal. Upon receiving a start signal, the drive unit's variable frequency speed control function precisely adjusts the motor speed according to actual production needs, thereby controlling the diaphragm pump's flow rate. The drive unit's internal fault self-diagnosis system monitors motor operating parameters in real time. Once an abnormality is detected, such as excessive current or excessive temperature, an alarm is immediately issued through the controller, and the operating mode is automatically adjusted or the pump stops operating based on the fault condition. The diaphragm pump gradually increases its speed according to a preset start-up curve to avoid excessive impact on the pipeline system. When stopping, the speed is gradually reduced until the sauce inside the diaphragm is mostly emptied before stopping.
[0059] Buffering and Flow Stabilization: The sauce flows from the mixing tanker into the buffer tank via the feeding section. A level monitoring device on the buffer tank monitors the liquid level in real time. When the flow rate fluctuates in the feeding section, the buffer tank stabilizes the liquid level through its storage and release functions, thereby stabilizing the sauce flow rate in the discharging section. If the pressure inside the buffer tank rises abnormally, the safety valve automatically opens to release the pressure, ensuring system safety. The discharging section then delivers the sauce with stable flow and pressure to the vertical packaging machine.
[0060] The beneficial effects of this embodiment are as follows:
[0061] Higher measurement accuracy: The temperature compensation function of the liquid level sensor makes the liquid level measurement more accurate, effectively avoiding measurement errors caused by temperature changes, and providing more reliable data support for the precise delivery of sauces.
[0062] More flexible flow regulation: The variable frequency speed control function of the diaphragm pump can precisely adjust the flow rate according to production needs, meet the requirements of different production conditions, and improve the flexibility and adaptability of production.
[0063] Enhanced safety and reliability: The drive unit's self-diagnostic system can promptly detect and address potential faults, preventing equipment damage and production interruptions. The inclusion of buffer tanks and safety valves ensures stable operation of the piping system under conditions of feed fluctuations and abnormal pressure, further improving the overall system's safety and reliability.
[0064] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
