Description

Technical Field

[0001] This application relates to the field of infusion control technology, and in particular to a quantitative infusion control system for glue preparation. Background Technology

[0002] In the field of adhesive preparation, precise control of liquid delivery is one of the key steps to ensure product quality and performance stability. The adhesive preparation process typically requires mixing various liquid raw materials (such as resins, curing agents, and solvents) in specific proportions to achieve the desired adhesive strength, curing speed, and other physicochemical properties. As a core piece of equipment, the quantitative dispensing control device plays a crucial role in adhesive preparation, and its performance directly affects the accuracy of adhesive mixing and product consistency. With the continuous expansion of adhesive applications (such as electronic packaging, automotive manufacturing, and building bonding), higher demands are being placed on the precision, stability, and intelligence of quantitative dispensing control systems.

[0003] Currently, the commonly used quantitative infusion control devices in adhesive preparation mainly employ negative pressure suction or gravity drive to achieve liquid delivery. Negative pressure suction uses a vacuum pump to generate negative pressure, drawing the liquid from the storage container and delivering it to the mixing device; gravity drive relies on the liquid's own weight, controlling the flow rate by adjusting the height difference of the delivery pipeline. While these methods are simple in structure and low in cost, they have significant limitations in practical applications. For example, negative pressure suction is easily affected by pipeline sealing and negative pressure stability, leading to large flow rate fluctuations; gravity drive is sensitive to liquid viscosity and environmental conditions (such as temperature and air pressure), making it difficult to adapt to the delivery requirements of different adhesive raw materials.

[0004] Traditional negative pressure suction infusion methods are prone to flow instability in glue preparation due to poor pipeline sealing or negative pressure fluctuations, which affects the accuracy of glue mixing ratio and reduces the infusion accuracy of the device. Utility Model Content

[0005] The purpose of this application is to address the problem that traditional negative pressure suction infusion methods are prone to flow instability in glue preparation due to poor pipeline sealing or negative pressure fluctuations, which affects the accuracy of glue mixing ratio and reduces the infusion accuracy of the device. This application provides a quantitative infusion control system for glue preparation.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A quantitative infusion control system for adhesive preparation includes a storage tank. A first connecting pipe is fixedly connected to the output end of the storage tank. A second connecting pipe is installed at the output end of the first connecting pipe. A metering pump is fixedly connected to the output end of the second connecting pipe. A third connecting pipe is fixedly connected to the output end of the metering pump. A temperature control box is fixedly connected to the output end of the third connecting pipe. A fourth connecting pipe is fixedly connected to the output end of the temperature control box. A connector is fixedly connected to the output end of the fourth connecting pipe. A flow sensor is fixedly connected to the input end of the fourth connecting pipe. A controller is fixedly connected to one side of the storage tank. The controller is electrically connected to the metering pump and the flow sensor.

[0008] By adopting the above technical solution, and by setting up the controller in conjunction with the metering pump and flow sensor, it is easy to preset the required parameters through the controller, and make the metering pump rotate according to the frequency preset by the controller. This allows the metering pump to pump a metered amount of liquid through the first connecting pipe, the second connecting pipe, the third connecting pipe, the temperature control box, the fourth connecting pipe, and the connector to inject it into the next process. At the same time, the flow sensor monitors the liquid flow rate inside the fourth connecting pipe in real time, and the controller adjusts the output efficiency of the metering pump according to the monitoring value of the flow sensor, thereby effectively improving the liquid output accuracy of the device.

[0009] Furthermore, a heat exchange copper plate is fixedly connected to one side of the temperature control box, an electric heating wire is fixedly connected to one side of the heat exchange copper plate, a temperature sensor is fixedly connected inside the temperature control box, and the temperature sensor is electrically connected to the controller.

[0010] By adopting the above technical solution, and by setting up the combination of electric heating wire, temperature sensor, and heat exchange copper plate, it is convenient to start the electric heating wire to heat the heat exchange copper plate according to the real-time liquid temperature change monitored by the temperature sensor, and to adjust the real-time temperature of the liquid by exchanging heat with the liquid passing through the temperature control box, thereby further improving the liquid delivery accuracy of the device.

[0011] Furthermore, the interior of the temperature control box is uniformly and fixedly connected with multiple guide plates, which are staggered between adjacent guide plates to form an S-shaped flow channel.

[0012] By adopting the above technical solution, and by using the combination of the guide plate and the S-shaped flow channel, the travel distance of the liquid through the inside of the temperature control box is effectively extended, thereby making the heat exchange between the liquid and the heat exchange copper plate more complete and effectively improving the heating efficiency of the device.

[0013] Furthermore, the fourth connecting pipe is externally fixed with a rock wool insulation sleeve.

[0014] By adopting the above technical solution and using the fourth connecting pipe in conjunction with the rock wool insulation sleeve, the insulation effect of the fourth connecting pipe is effectively improved, the temperature change of the liquid when passing through the inside of the fourth connecting pipe is reduced, and the practicality of the device is improved.

[0015] Furthermore, a water pressure sensor is fixedly connected to the output end of the fourth connecting pipe, and the controller is electrically connected to the water pressure sensor.

[0016] By adopting the above technical solution and using the water pressure sensor and controller in conjunction, the output frequency of the metering pump can be adjusted by the controller according to the liquid pressure changes monitored by the water pressure sensor, thereby further improving the infusion accuracy of the device.

[0017] Furthermore, a filter cone is inserted into the input end of the second connecting pipe, and a threaded sleeve is provided at the input end of the second connecting pipe. A threaded sleeve is rotatably connected to the output end of the first connecting pipe, and the threaded sleeve is threadedly connected to the threaded sleeve.

[0018] By adopting the above technical solution, and by setting the filter cone to work in conjunction with the screw-in sleeve and the screw-in socket, it is convenient to form a threaded connection when the screw-in sleeve and the screw-in socket are tightened and the filter cone is pushed to be fixed inside the second connecting pipe. This allows the filter cone to intercept and filter the liquid flowing into the second connecting pipe through the first connecting pipe, thereby reducing the possibility of foreign objects in the liquid clogging the inside of the metering pump and improving the safety of the device.

[0019] Furthermore, one end of the filter cone is symmetrically provided with positioning holes, and one end of the second connecting pipe is symmetrically fixedly connected with a positioning rod, one end of which is inserted into the interior of the positioning hole.

[0020] By adopting the above technical solution and using the positioning hole and positioning rod in combination, the installation state of the filter cone can be defined, thereby reducing the possibility of the filter cone becoming loose between the first connecting pipe and the second connecting pipe, and further improving the infusion accuracy of the device.

[0021] Furthermore, the input end of the second connecting pipe is fixedly fitted with a first rubber sealing ring, the output end of the first connecting pipe is fixedly fitted with a second rubber sealing ring, and one end of the filter cone is installed between the first rubber sealing ring and the second rubber sealing ring.

[0022] By adopting the above technical solution, and by setting the first rubber sealing ring and the second rubber sealing ring to work together, the elastic characteristics of the first rubber sealing ring and the second rubber sealing ring are utilized to make the first rubber sealing ring and the heat exchange copper plate fill the space between the first connecting pipe and the second connecting pipe under force, which effectively improves the sealing effect of the device.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. By setting up the controller in conjunction with the metering pump and flow sensor, the controller can preset the required parameters and make the metering pump rotate according to the preset frequency. This allows the metering pump to draw a fixed amount of liquid through the first connecting pipe, the second connecting pipe, the third connecting pipe, the temperature control box, the fourth connecting pipe, and the connector to inject it into the next process. At the same time, the flow sensor can monitor the liquid flow rate inside the fourth connecting pipe in real time, and the controller can adjust the output efficiency of the metering pump according to the monitoring value of the flow sensor, thereby effectively improving the liquid output accuracy of the device.

[0025] 2. By setting up the filter cone to work in conjunction with the screw-in sleeve and the screw-in socket, it is easy to form a threaded connection when the screw-in sleeve and the screw-in socket are tightened and the filter cone is pushed to be fixed inside the second connecting pipe. This allows the filter cone to intercept and filter the liquid flowing into the second connecting pipe through the first connecting pipe, thereby reducing the possibility of foreign objects in the liquid clogging the metering pump and improving the safety of the device.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a quantitative infusion control system for glue preparation.

[0033] Reference Figures 1-3A quantitative infusion control system for glue preparation includes a storage tank 1. A first connecting pipe 2 is fixedly connected to the output end of the storage tank 1. A second connecting pipe 3 is installed at the output end of the first connecting pipe 2. A quantitative pump 4 is fixedly connected to the output end of the second connecting pipe 3. A third connecting pipe 5 is fixedly connected to the output end of the quantitative pump 4. A temperature control box 6 is fixedly connected to the output end of the third connecting pipe 5. A fourth connecting pipe 7 is fixedly connected to the output end of the temperature control box 6. A connector 8 is fixedly connected to the output end of the fourth connecting pipe 7. A flow sensor 9 is fixedly connected to the input end of the fourth connecting pipe 7. A controller 10 is fixedly connected to one side of the storage tank 1. The controller 10 is electrically connected to the quantitative pump 4 and the flow sensor 9.

[0034] Among them, a heat exchange copper plate 23 is fixedly connected to one side of the temperature control box 6, an electric heating wire 11 is fixedly connected to one side of the heat exchange copper plate 23, a temperature sensor 12 is fixedly connected inside the temperature control box 6, and the temperature sensor 12 is electrically connected to the controller 10.

[0035] Furthermore, multiple guide plates 13 are evenly and fixedly connected inside the temperature control box 6, with adjacent guide plates 13 arranged alternately to form an S-shaped flow channel;

[0036] Furthermore, the fourth connecting pipe 7 is fixedly fitted with a rock wool insulation sleeve 14.

[0037] In use, the output parameters of the metering pump 4 are first set by the controller 10, which then sends a command to the metering pump 4 according to the preset parameters. This causes the metering pump 4 to rotate at a set frequency, pumping the liquid inside the storage tank 1 evenly through the first connecting pipe 2 and the second connecting pipe 3, and then into the temperature control box 6 through the third connecting pipe 5. Simultaneously, the temperature sensor 12 inside the temperature control box 6 monitors the temperature of the delivered liquid in real time and transmits the temperature signal to the controller 10. Then, the controller 10 activates the electric heating wire 11 according to the preset temperature value, causing the electric heating wire 11 to self-heat and heat the heat exchange copper plate 23. The heat exchange copper plate 23 then heats the liquid passing through the temperature control box 6 to the preset temperature. Multiple guide plates 13 are also installed. The staggered S-shaped flow channels guide the liquid to flow through the interior of the temperature control box 6, effectively extending the liquid's travel distance through the box. This allows the liquid to fully contact and exchange heat with the heat exchange copper plate 23, improving the heating efficiency of the electric heating wire 11. Finally, when the liquid is transferred to the next process via the fourth connecting pipe 7 and connector 8, the flow sensor 9 monitors the liquid flow rate inside the fourth connecting pipe 7 in real time. The controller 10 adjusts the output efficiency of the metering pump 4 based on the monitoring value of the flow sensor 9. At the same time, the rock wool insulation jacket 14 provides insulation and protection for the liquid flowing through the fourth connecting pipe 7, reducing temperature changes when the liquid is output through connector 8 and effectively improving the liquid output accuracy of the device.

[0038] Reference Figures 1-3 The output end of the fourth connecting pipe 7 is fixedly connected to a water pressure sensor 15, and the controller 10 is electrically connected to the water pressure sensor 15.

[0039] The input end of the second connecting pipe 3 is provided with a filter cone 16, and the input end of the second connecting pipe 3 is provided with a screw sleeve 17. The output end of the first connecting pipe 2 is rotatably connected with a screw sleeve 18, and the screw sleeve 18 is threadedly connected to the screw sleeve 17.

[0040] Furthermore, a positioning hole 19 is symmetrically opened at one end of the filter cone 16, and a positioning rod 20 is symmetrically fixedly connected to one end of the second connecting pipe 3, with one end of the positioning rod 20 inserted into the interior of the positioning hole 19.

[0041] Furthermore, the input end of the second connecting pipe 3 is fixedly fitted with a first rubber sealing ring 21, the output end of the first connecting pipe 2 is fixedly fitted with a second rubber sealing ring 22, and one end of the filter cone 16 is installed between the first rubber sealing ring 21 and the second rubber sealing ring 22.

[0042] In use, firstly, the water pressure sensor 15 is set to monitor the liquid pressure inside the fourth connecting pipe 7 in real time. When the water pressure sensor 15 detects a change in liquid pressure exceeding a preset value, the controller 10 sends an alarm message to the operator. Then, the operator is guided to loosen the threaded sleeve 18, so that the threaded sleeve 18 is released from the threaded connection with the threaded sleeve head 17, and the first connecting pipe 2 is disengaged from the fixed connection with the second connecting pipe 3. Next, the filter cone 16 is manually pulled to move along the length of the positioning rod 20, and the positioning rod 20 is disengaged from the interior of the positioning hole 19, so that the filter cone 16 is disengaged from the interior of the second connecting pipe 3. Then, the foreign objects filtered and intercepted inside the filter cone 16 are cleaned. Finally, the filter cone 16 is pulled and cleaned. The filter cone 16 then moves the positioning hole 19 onto one end of the positioning rod 20, and the screw sleeve 18 is tightened, so that the screw sleeve 18 and the screw head 17 form a threaded connection. This causes the first connecting pipe 2 and the second connecting pipe 3 to move closer together along the length of the positioning rod 20. At the same time, the first connecting pipe 2 and the second connecting pipe 3 push the second rubber sealing ring 22 and the first rubber sealing ring 21 to clamp and resist one end of the filter cone 16. Utilizing the elastic properties of the first rubber sealing ring 21 and the second rubber sealing ring 22, the first rubber sealing ring 21 and the second rubber sealing ring 22 fill the connection end of the first connecting pipe 2 and the second connecting pipe 3, effectively improving the sealing effect between the first connecting pipe 2 and the second connecting pipe 3.

[0043] The implementation principle of the quantitative infusion control system for adhesive preparation in this embodiment is as follows: First, the controller 10 sends a command to the quantitative pump 4 according to preset parameters, causing the quantitative pump 4 to draw the liquid inside the storage tank 1 evenly through the first connecting pipe 2 and the second connecting pipe 3, and input it into the temperature control box 6 through the third connecting pipe 5. At the same time, the temperature sensor 12 installed inside the temperature control box 6 monitors the temperature of the delivered liquid in real time and transmits the temperature signal to the controller 10. Then, the controller 10 activates the electric heating wire 11 according to the preset temperature value, thereby causing the electric heating wire 11 to self-heat and heat the heat exchange copper plate 23, and causing the heat exchange copper plate 23 to pass through the liquid. The liquid inside the temperature control box 6 is heated to a preset temperature. At the same time, multiple guide plates 13 are arranged in an S-shaped flow channel to guide the liquid to flow through the inside of the temperature control box 6 in an S-shape. This effectively extends the travel distance of the liquid through the temperature control box 6, allowing the liquid to fully contact and exchange heat with the heat exchange copper plate 23, thus improving the heating efficiency of the electric heating wire 11. Finally, when the liquid is transferred to the next process through the fourth connecting pipe 7 and the connector 8, the flow sensor 9 monitors the flow rate of the liquid entering the fourth connecting pipe 7 in real time, and the controller 10 adjusts the output efficiency of the metering pump 4 according to the monitoring value of the flow sensor 9.

[0044] Then, when the water pressure sensor 15 detects that the liquid pressure change exceeds the preset value, the controller 10 sends an alarm message to the staff. Then, the staff is guided to loosen the screw sleeve 18, so that the screw sleeve 18 is released from the threaded connection with the screw head 17, and the first connecting pipe 2 is disengaged from the fixed connection with the second connecting pipe 3. Next, the filter cone 16 is manually pulled to move along the length of the positioning rod 20, and the positioning rod 20 is pulled out of the interior of the positioning hole 19, so that the filter cone 16 is disengaged from the interior of the second connecting pipe 3. Then, the foreign objects filtered and intercepted inside the filter cone 16 are cleaned. Finally, the cleaned filter cone 16 is pulled to move the positioning hole 19 onto one end of the positioning rod 20, and the screw sleeve 18 is tightened, so that the screw sleeve 18 and the screw head 17 form a threaded connection.
