Description

Technical Field

[0001] The present application relates to a program-controlled quantitative sealing machine, and in particular to a portable program-controlled quantitative sealing machine. Background Art

[0002] In recent years, with the establishment of "National Ecological Day" and the improvement of public awareness of ecological environmental protection, the importance of water quality monitoring and water ecological management has become increasingly prominent. Water quality testing is not only the basis for evaluating water resource quality and protecting water ecological health, but also a key link in ensuring human health and social sustainable development. Among the many water quality testing items, the detection of microbial indicators is particularly important, among which the detection of total coliform group is an important indicator for evaluating water quality safety.

[0003] Traditional water quality testing methods include membrane filtration method and enzyme substrate method. Among them, the enzyme substrate method has gradually become the preferred method for field water quality testing due to its simple operation, low requirements for environmental conditions, and especially the advantage of not requiring a sterile environment for operation. However, GB5750.2-2023 "Standard Test Methods for Drinking Water Part 2: Collection and Storage of Water Samples" clearly stipulates that collected water samples should be tested as soon as possible, especially microbial indicators. If they are not tested in time, they should be stored at 0-4°C and the storage time should not exceed 8 hours. This regulation is often difficult to complete within the specified time in a vast geographical area due to inconvenient transportation and uneven distribution of testing resources.

[0004] In remote areas, especially in environments with harsh natural conditions or imperfect infrastructure, the 8-hour shelf life poses a severe challenge to the effectiveness of samples. Therefore, the on-site instant detection capability of the enzyme substrate method becomes particularly critical. However, most of the enzyme substrate method detection equipment on the market, especially the program-controlled quantitative sealing machine, is designed for fixed laboratory use, relies on high-power AC power, lacks portability and feasibility for outdoor use, which greatly limits its application in the wild or remote areas.

[0005] In view of the above background, the utility model aims to solve the shortcomings of the prior art and provide an enzyme substrate method programmable quantitative sealing machine suitable for outdoor environments and capable of operating without a stable power supply, so as to meet the urgent needs of on-site water quality testing in remote areas and ensure the accuracy and timeliness of microbial indicator testing. Utility Model Content

[0006] The purpose of this application is to provide a portable program-controlled quantitative sealing machine in view of the above-mentioned problems existing in the prior art.

[0007] In order to achieve the above application purpose, the present application adopts the following technical solution: a portable program-controlled quantitative sealing machine, comprising a device body and a sealing actuator arranged in the device body, the sealing actuator comprising a heating roller, a driving roller and a driving motor for driving the driving roller to rotate, and the device body also includes:

[0008] DC power socket, used to connect to DC power supply;

[0009] AC power socket, used to connect to AC power;

[0010] A power management module is electrically connected to the DC power socket and the AC power socket respectively;

[0011] An inverter, electrically connected to the power management module, for converting direct current into alternating current and outputting it to the MCU controller;

[0012] The MCU controller is electrically connected to the power management module, the inverter and the sealing actuator respectively, and is used to control the sealing actuator;

[0013] Among them, the MCU controller has a built-in PID temperature control module for controlling the temperature of the heating roller of the sealing actuator.

[0014] Furthermore, the outer shell of the device body is made of ABS material.

[0015] Furthermore, the internal frame of the device body is made of aluminum alloy.

[0016] Furthermore, a carrying handle is provided on the top of the device body.

[0017] Furthermore, the DC power socket and the AC power socket are both installed on the socket panel on the side of the device body.

[0018] Furthermore, a power switch is also provided on the socket panel.

[0019] Furthermore, a start button and an indicator light are provided on the main body of the device. The indicator light is used to display the working status of the sealing actuator and displays different statuses in different colors.

[0020] Furthermore, the diameter of the heating roller is not greater than 30 mm.

[0021] Furthermore, the device body is also provided with a sealing disk entrance.

[0022] Furthermore, the DC power socket and the AC power socket are located on the same straight line.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] 1. Efficient preheating and energy-saving design

[0025] Reduce the diameter of the heating roller: By reducing the size of the heating roller (the diameter is no more than 30mm, and the existing ones are often more than 50mm), the total amount of heat required for preheating is greatly reduced, thereby shortening the preheating time and reducing energy consumption. Combined with the mature intelligent PID temperature control algorithm, the heating process can be accurately controlled to avoid overheating and further save energy.

[0026] 2. Lightweight and portable design

[0027] Shell and internal structure material selection: ABS plastic is used as the shell material, which is light and has good impact resistance; the internal structure uses aluminum alloy, which not only reduces the overall weight but also provides the necessary strength and durability. This lightweight design makes the equipment easy to carry and is particularly suitable for outdoor operating environments.

[0028] 3. Multi-power compatibility and versatility

[0029] Power input and management: The device supports AC power and DC power input, and is powered directly by the power management module or converted by an inverter. This design allows the device to maintain efficient operation in different working environments, whether it is outdoor operation or indoor laboratory use, it can easily cope with it.

[0030] In summary, through technological innovation, this solution has achieved significant improvements in preheating efficiency, energy consumption management, portability, and power compatibility, demonstrating its practicality in the field of sealing equipment.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0038] Those skilled in the art should understand that, in the disclosure of the present application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present application.

[0039] like Figure 1-3 As shown, the portable program-controlled quantitative sealing machine includes a device body 1, on which a sealing actuator 2 and a sealing plate inlet 13 for feeding are provided. The sealing actuator 2 includes a heating roller 21, a driving roller 22 and a driving motor 23 for driving the driving roller 22 to rotate. The main principle belongs to the prior art and will not be repeated here. The improvements are as follows:

[0040] 1. In this solution, the diameter of the heating roller 21 is reduced and controlled within 30 mm. The heat required for preheating is smaller. Combined with the intelligent PID temperature control algorithm in the MCU controller, the preheating time is shorter and the energy consumption is lower.

[0041] 2. The shell of the device body 1 is made of ABS material, and the internal structure, such as the frame part, is made of aluminum alloy, with a lightweight design. The shell is provided with a carrying handle 16, which is more convenient to carry and can meet the needs of outdoor use in any location.

[0042] 3. The key point is that the device body 1 also includes:

[0043] A DC power socket 11, used for connecting to a DC power source;

[0044] AC power socket 12, used for connecting to AC power;

[0045] The power management module 5 is electrically connected to the DC power socket 11 and the AC power socket 12 respectively, and is used to detect whether the input power is DC or AC;

[0046] The inverter 14 is electrically connected to the power management module 5 and is used to convert direct current into alternating current and output it to the MCU controller 15;

[0047] The MCU controller 15 is electrically connected to the power management module 5 , the inverter 14 and the sealing actuator 2 , respectively, and is used to control the sealing actuator 2 ; wherein the MCU controller 15 has a built-in PID temperature control module, which is used to control the temperature of the heating roller 21 of the sealing actuator 2 .

[0048] Preferably, the DC power socket 11 and the AC power socket 12 are both installed on the socket panel 17 on the side of the device body 1, the DC power socket 11 and the AC power socket 12 are located in the same straight line, and a power switch 18 is also provided on the socket panel 17. The device body 1 is provided with a start button 4 and an indicator light 3, the indicator light 3 is used to display the working state of the sealing actuator 2, and different states are displayed in different colors.

[0049] The working principle is as follows: the user connects to the power supply, which can be AC ​​power or DC power, and can be selected according to the site conditions. Turn on the power switch 18, and the power management module 5 detects the input power type. If it is AC power, it directly supplies power to the MCU controller 15 and the actuator. If the input power is DC power, the power is converted by the inverter 14 and then supplied to the MCU controller 15 and the sealing actuator 2. The instrument starts normal heating and preheating, and the preheating state is judged according to the state of the indicator light 3. After the preheating is completed, the quantitative disk is placed from the sealing disk entrance 13, and the driving motor 23 drives the driving roller 22 to rotate, and the quantitative disk is transmitted through the heating roller 21 for extrusion and heat sealing, and the sample sealing disk processing is completed. With the optional power supply form of AC power supply and DC power supply, the equipment can be used outdoors or in conventional laboratories, realizing multiple uses of one machine.

[0050] Among them, the PID temperature control algorithm is a control strategy widely used in temperature control systems. It uses three control functions, proportional (P), integral (I) and derivative (D), to adjust the control quantity, thereby accurately maintaining the system temperature near a set value. The core of this algorithm is to calculate an appropriate control signal in real time, which can adjust the intensity of heating or cooling according to the current temperature deviation (i.e. the difference between the set temperature and the actual temperature).

[0051] Among them, the inverter 14 is a power electronic device whose main function is to convert direct current (DC) into alternating current (AC). This process is called inversion. The MCU controller refers to a microcontroller unit (MCU), which is a small computer system integrated on a chip and is specially designed to control specific functions in electronic devices. The MCU controller contains a central processing unit (CPU), memory (RAM and ROM), input / output interface, timer, analog-to-digital converter (ADC), digital-to-analog converter (DAC) and other control circuits. These components work together to enable the MCU to perform various control and computing tasks.

[0052] The process of identifying the power type by the power management module 5 usually involves detecting the characteristics of the input voltage to determine whether it is alternating current (AC) or direct current (DC). This process can be implemented by hardware circuits, and the specific method is as follows (not limited in this application):

[0053] 1. Voltage detection:

[0054] 1.1 AC power detection: The characteristic of AC power is that the voltage fluctuates over time, usually in the form of a sine wave. The power management module 5 can determine whether it is AC power by detecting whether there is a periodic change in the voltage. For example, using a voltage peak detection circuit or a zero crossing detection circuit, if it is detected that the voltage crosses the zero point multiple times within a certain period of time, it can be confirmed as AC power.

[0055] 1.2 DC power supply detection: The voltage of a DC power supply is relatively stable and does not change direction. By detecting whether the voltage remains at a stable level without periodic positive and negative alternation, it can be determined to be a DC power supply.

[0056] 2. Frequency detection:

[0057] For AC power, the power management module 5 can also detect the frequency of the voltage. The standard grid voltage frequency is usually 50 Hz or 60 Hz, which can help further confirm the power type.

[0058] 3. Current detection:

[0059] In addition to voltage, current characteristics can also help distinguish power types. For example, the current of an AC power source will also vary over time, while the current of a DC power source is relatively stable.

[0060] 4. Use dedicated chips:

[0061] Modern power management systems often integrate dedicated chips with built-in complex algorithms that can automatically detect and identify power types. They may combine the above-mentioned detection methods to provide accurate and reliable power type identification.

[0062] Or as Figure 4 As shown in the figure, when AC is input, the normally open contact of AC relay KM1 is closed, the normally open contact of DC relay KM2 is disconnected, and AC power is transmitted to the MUC controller. Figure 5 As shown, when DC power is input, the normally open contact of DC relay KM2 is closed, and the DC power is sent to the MCU controller after inversion; when the two lines are connected together, the normally open contact of AC relay KM1 is closed, and the normally open contact of DC relay KM2 is disconnected, and AC power supply is used first.

[0063] The parts not described in detail in this application are prior art, so this application does not describe them in detail.

[0064] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0065] Although this article uses more terms such as device body 1, sealing actuator 2, indicator light 3, start button 4, power management module 5, DC power socket 11, AC power socket 12, sealing disk inlet 13, inverter 14, MCU controller 15, carrying handle 16, socket panel 17, power switch 18, heating roller 21, driving roller 22, driving motor 23, etc., it does not exclude the possibility of using other terms. The use of these terms is only for more convenient description and explanation of the essence of this application; interpreting them as any additional restrictions is contrary to the spirit of this application.

[0066] The present application is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of this application. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present application.
