Description

Technical Field

[0001] This utility model relates to the technical field of glass glue mixing equipment, and in particular discloses an energy-saving servo motor driven glass glue mixing equipment. Background Technology

[0002] Existing glass sealant mixing equipment suffers from several shortcomings: low precision in material conveying ratio control, leading to an imbalance in the mixing ratio of base material and resin, resulting in unstable product quality; poor mixing uniformity, affecting the performance of the glass sealant. The equipment consumes a large amount of energy, with significant waste of redundant energy in the hydraulic system during operation, and pressure fluctuations causing unstable conveying, exacerbating equipment wear and increasing maintenance costs. The hydraulic system lacks specialized division of labor, making it difficult to adapt to the different characteristics of base materials, resins, and the mixed glass sealant, resulting in insufficient conveying efficiency and accuracy. The hydraulic station piping is complex, posing a high risk of leakage and making maintenance inconvenient. The pipeline system has chaotic paths, making it prone to material stagnation and difficult to clean. The lack of an effective monitoring and control mechanism leads to abnormal flow rates during production, relying on manual intervention and resulting in large errors. Furthermore, the flexibility and reliability of material conveying are insufficient, and unidirectional flow assurance is lacking, making it difficult to meet diverse production needs. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an energy-saving servo motor driven glass glue mixing device.

[0004] To achieve the above objectives, this utility model discloses an energy-saving servo motor-driven glass glue mixing device, comprising a frame, a control cabinet mounted on the frame, a hydraulic system, a piping system, a servo system, a static mixer, and an energy storage device. The control cabinet is electrically connected to the hydraulic system and the servo system. Each system, the static mixer, and the energy storage device are connected to the piping system. The servo system includes a servo pump set, a first servo metering unit for metering the base material, and a second servo metering unit for metering the resin. The outlet of each servo metering unit is connected to the inlet of the static mixer through the piping system. The servo pump set is connected to the hydraulic system, driving the hydraulic system to provide power for the conveying of the base material and resin. The base material and resin are forcibly mixed in the static mixer through its internal structure. The energy storage device is connected to the conveying path of the base material, resin, and / or auxiliary solvent in the piping system. During the pulse conveying process of the servo system, it stores a portion of the base material, resin, and / or auxiliary solvent at the peak of the pulse and releases the stored base material, resin, and / or auxiliary solvent when the servo system is in the pulse interval.

[0005] This equipment demonstrates significant comprehensive advantages through the coordinated operation of multiple systems. The first and second servo metering units in the servo system precisely control the delivery volume of the base material and resin, ensuring they enter the static mixer in the ideal ratio, laying the foundation for high-quality mixing. The static mixer, with its unique internal structure, forces the base material and resin to mix, significantly improving mixing uniformity and ensuring stable quality of the glass sealant product. The energy storage device is particularly crucial. Connected to the delivery path of the base material, resin, and / or auxiliary solvent in the pipeline system, it stores a portion of the material during peak pulse delivery times in the servo system and releases it during pulse breaks, effectively maintaining the continuity and pressure stability of material delivery within the pipeline system. This not only ensures the accuracy of the ratio of base material and resin entering the static mixer and reduces delivery instability caused by pressure fluctuations, but also helps improve the consistency of the mixing effect. Simultaneously, this design avoids material delivery interruptions, ensuring continuous and stable operation of the equipment, extending its service life, and reducing maintenance costs.

[0006] Furthermore, the hydraulic system includes a hydraulic station, a first hydraulic metering unit connected to the hydraulic station for conveying the base material or resin, and a second hydraulic metering unit for conveying the glass glue formed by mixing the two.

[0007] This structural design of the hydraulic system enables specialized division of labor in material conveying, bringing numerous benefits. The first hydraulic metering unit is specifically responsible for conveying the base material or resin, enabling precise control based on the different physical properties of the base material and resin (such as viscosity and flowability), ensuring a stable and efficient conveying process. The second hydraulic metering unit focuses on conveying the mixed silicone sealant. Since the properties of the mixed silicone sealant differ from those of the base material and resin, the specialized conveying unit can better adapt to its characteristics, avoiding problems such as poor conveying or inaccurate conveying volume caused by changes in material properties. This clearly defined division of labor not only improves the targeting and precision of conveying at each stage but also makes the entire material conveying process more orderly, reducing mutual interference between different material conveying processes, improving the overall operating efficiency and reliability of the equipment, and providing strong support for the continuity of silicone sealant production.

[0008] Furthermore, the hydraulic station includes an oil tank, an oil circuit block integrated on the oil tank, and a first solenoid valve group disposed on the oil circuit block; the servo pump group draws hydraulic oil from the oil tank and pumps it into the oil circuit block, and the hydraulic oil is regulated by the first solenoid valve group and then delivered to the first hydraulic metering unit and the second hydraulic metering unit respectively to provide them with a power source.

[0009] This integrated design of the hydraulic power unit offers numerous advantages. The oil tank provides a stable storage space for hydraulic oil, ensuring an ample supply to the hydraulic system. The manifold block, integrated into the oil tank, simplifies the piping connections of the hydraulic system, reduces the complexity of the piping layout, lowers the risk of hydraulic oil leakage, and also facilitates equipment installation and maintenance. The first solenoid valve group, located on the manifold block, enables centralized and precise control of hydraulic oil delivery. After the servo pump draws hydraulic oil and pumps it into the manifold block, the first solenoid valve group regulates the flow of hydraulic oil, ensuring that the oil is accurately delivered to the first and second hydraulic metering units as needed, guaranteeing appropriate power supply to each unit. This centralized control method not only improves the efficiency of hydraulic oil delivery but also allows for flexible adjustment of the oil supply status according to the working needs of different units, ensuring stable operation of each hydraulic metering unit and thus enhancing the overall reliability and stability of the equipment.

[0010] Furthermore, the piping system has an input end and an output end. The input end is connected to the first hydraulic metering unit to input the initial conveying power of the base material or resin, and the output end is connected to the second hydraulic metering unit to output the mixed glass glue. The static mixer is located in the piping system between the two hydraulic metering units.

[0011] This structural design of the pipeline system provides a rational path for material conveying and mixing. Clearly defined input and output ends make the conveying paths of the base material and resin, as well as the output path of the silicone sealant, clearly identifiable, avoiding material conveying errors or blockages caused by chaotic piping. The input end connects to the first hydraulic metering unit, effectively receiving the initial conveying power from this unit, ensuring the smooth entry of the base material and resin into the pipeline system and its delivery to the static mixer. The static mixer is located in the pipeline system between the two hydraulic metering units; this placement is highly efficient, allowing the base material and resin to naturally and smoothly enter the mixer for mixing during the conveying process, eliminating the need for additional power or complex guiding structures and improving mixing efficiency. The output end connects to the second hydraulic metering unit, facilitating the smooth output of the mixed silicone sealant under the action of this unit, completing the entire production process. This clear path design reduces the residence time of materials in the pipeline, simplifies pipeline cleaning, and also facilitates daily equipment inspection and maintenance.

[0012] Furthermore, the servo metering unit includes a support frame, a first three-way cylinder fixedly mounted on the support frame, and a servo drive assembly, an input cylinder assembly, and an output cylinder assembly reciprocatingly mounted on the support frame. Each of the three assemblies has a piston rod at its output end, and the reciprocating motion direction of the piston rods of the three assemblies corresponds one-to-one with the three guiding directions of the first three-way cylinder. The input cylinder assembly is used to input the base material or resin, and the output cylinder assembly outputs the base material or resin to the static mixer. The three assemblies work together to quantitatively deliver the base material or resin.

[0013] This structural design of the servo metering unit greatly improves the accuracy and reliability of the quantitative delivery of base material and resin. The support frame provides a stable mounting base for each component, ensuring the stability of each part's position during operation and reducing misalignment caused by factors such as vibration. The fixed setting of the first three-way cylinder body is coordinated with the reciprocating motion settings of the servo drive assembly, input cylinder assembly, and output cylinder assembly. The reciprocating motion direction of the piston rods of the three components corresponds one-to-one with the three guide directions of the first three-way cylinder body, forming a precise motion coordination relationship. The input cylinder assembly is specifically responsible for the input of base material or resin, while the output cylinder assembly focuses on outputting the material to the static mixer. The servo drive assembly coordinates the input and output processes through precise control to achieve quantitative delivery. This collaborative working mode of the three components ensures that the input, metering, and output processes of the material are closely linked, enabling precise control of the amount of material delivered each time. This provides a solid guarantee for the accuracy of the subsequent mixing ratio of base material and resin, thereby ensuring the quality stability of the glass glue product. At the same time, the clear division of labor among the components also facilitates individual maintenance and replacement, reducing equipment maintenance costs.

[0014] Furthermore, the frame is equipped with a second solenoid valve group and a flow meter group electrically connected to the control cabinet. The flow meter group is used to monitor the flow signals of the base material and resin in each pipe section of the pipeline system and feed them back to the control cabinet. The second solenoid valve group includes multiple solenoid valves, each of which is connected to the corresponding pipe section and the metering unit at both ends to form a fluid passage. Each solenoid valve can independently or collaboratively control the on / off state between the corresponding pipe section and the metering unit according to the flow signal.

[0015] The second solenoid valve group and flow meter group enable precise monitoring and flexible control of the material conveying process, which is of great significance. The flow meter group can monitor the flow signals of the base material and resin in each pipe section of the pipeline system in real time and feed these signals back to the control cabinet in a timely manner. This allows operators to keep track of the material conveying status in real time and provides data support for monitoring and adjusting the production process. Once an abnormal flow is detected, measures can be taken in time to avoid product quality problems caused by flow deviations. The multiple solenoid valves in the second solenoid valve group are connected to the corresponding pipe sections and metering units, forming independent fluid paths. Each solenoid valve can work independently or collaboratively according to the flow signals fed back by the flow meter group to precisely control the on / off state between the corresponding pipe section and the metering unit. This control method is highly flexible and can quickly adjust the conveying status according to different flow conditions to ensure that the conveying ratio of base material and resin is always kept within the ideal range. At the same time, this automated monitoring and control mode reduces manual intervention, reduces human error, improves production efficiency and product quality stability, and also lays the foundation for intelligent operation of the equipment.

[0016] Furthermore, the hydraulic metering unit includes a support frame, a second three-way cylinder mounted on the support frame, a two-way rotating shaft passing through the interior of the second three-way cylinder, a shaft driver that drives the two-way rotating shaft to rotate, and a hydraulic drive assembly that reciprocates with the second three-way cylinder. The two-way rotating shaft has two positively connected liquid holes, and the output end of the hydraulic drive assembly has a piston rod. The reciprocating direction of the piston rod corresponds to one of the guiding directions of the second three-way cylinder. The second three-way cylinder is connected to the pipeline system along the other two guiding directions. The shaft driver drives the two-way rotating shaft to rotate to switch the delivery path of the fluid in the second three-way cylinder.

[0017] This structural design of the hydraulic metering unit endows the fluid delivery system with extremely high flexibility and precision. The support frame provides stable support for the entire unit, ensuring stable cooperation among all components during operation. The second and third-direction cylinders, as key channels for fluid delivery, are connected to the piping system to receive and deliver fluid. The positive cross-linking fluid passage on the second-direction shaft rotates under the drive of the shaft actuator, flexibly switching the fluid delivery path within the second and third-direction cylinders to adapt to different production needs, such as switching the delivery direction between different pipe sections to meet diverse process flows. The reciprocating motion of the piston rod of the hydraulic drive component corresponds to one of the guide directions of the second and third-direction cylinders. The movement of the piston rod allows for precise control of the fluid delivery volume, ensuring accurate metering. This structure organically combines path switching and metering control, enabling the hydraulic metering unit to flexibly adjust according to actual production conditions. This not only improves the adaptability of fluid delivery but also ensures the accuracy of the delivery volume, providing strong support for the efficient operation of the entire equipment and reducing the risk of equipment failure due to complex path switching.

[0018] Furthermore, the hydraulic metering unit is equipped with an auxiliary metering unit, which includes an auxiliary three-way cylinder mounted on a support frame and an auxiliary drive assembly for reciprocating motion. One guide direction of the auxiliary three-way cylinder corresponds to and cooperates with the auxiliary drive assembly. The auxiliary three-way cylinder is connected to the pipeline system along the other two guide directions. Pneumatic ball valves are installed on the two pipe sections of the pipeline system near the auxiliary three-way cylinder along the other two guide directions.

[0019] The auxiliary metering unit significantly enhances the adjustability and reliability of the hydraulic metering system. The cooperation between the auxiliary three-way cylinder and the auxiliary drive assembly allows for auxiliary adjustment of fluid delivery on top of the main hydraulic metering unit's operation, further improving the accuracy of metering. When the main unit experiences minor deviations or requires fine adjustments, the auxiliary unit can respond quickly, compensating for the main unit's shortcomings and ensuring accurate delivery. The connection method between the auxiliary three-way cylinder and the piping system allows it to integrate into the entire delivery process and participate in fluid delivery adjustment. Pneumatic ball valves on the pipe sections near the auxiliary three-way cylinder effectively control the connection between the auxiliary three-way cylinder and the piping system, enabling the auxiliary unit to flexibly enter or exit the delivery process as needed, avoiding unnecessary interference with the main delivery process. This design not only improves the accuracy and reliability of metering but also enhances the equipment's ability to handle complex operating conditions. When the main unit experiences a temporary failure, the auxiliary unit can, to a certain extent, replace the main unit, ensuring production continuity and reducing production interruption losses due to equipment failure.

[0020] Furthermore, the first solenoid valve group includes a solenoid relief valve for regulating the hydraulic system pressure, a solenoid directional valve for switching the oil circuit direction, and an electro-hydraulic directional valve for high flow and high pressure control. The three work together to achieve precise regulation of hydraulic system pressure, flow direction and flow rate, ensuring the power supply of the servo metering unit.

[0021] The coordinated operation of various valves in the first solenoid valve group provides crucial assurance for the stable operation of the hydraulic system. The solenoid relief valve precisely regulates the hydraulic system pressure, preventing excessive pressure from damaging the equipment and avoiding insufficient pressure from affecting the power supply to each unit, ensuring the system pressure remains within a reasonable range. The solenoid directional valve switches the oil circuit direction, allowing hydraulic oil to flow accurately to different hydraulic metering units according to their operational needs, ensuring each unit operates normally in sequence. The electro-hydraulic directional valve is suitable for high-flow, high-pressure control scenarios, precisely controlling the oil circuit when the hydraulic system requires high-flow, high-pressure oil supply, meeting the power demands of components such as the servo metering unit under specific operating conditions. These three types of valves, with their clear division of labor and coordinated operation, achieve comprehensive and precise control of the hydraulic system's pressure, flow direction, and flow rate, ensuring the servo metering unit receives a stable and suitable power supply. This not only improves the accuracy and reliability of the hydraulic system's operation but also extends the service life of hydraulic components, reduces equipment failure rates and maintenance costs, laying a solid hydraulic power foundation for the efficient operation of the entire equipment.

[0022] Furthermore, the piping system includes a one-way valve assembly and multiple shower head connectors. The one-way valve assembly is used to ensure the one-way flow of the base material, resin, and the silicone sealant formed by their mixture. The multiple shower head connectors achieve the centralized input of the base material and resin and the centralized output of the silicone sealant through a multi-channel diversion structure.

[0023] The one-way valve assembly and multiple shower head joints in the pipeline system offer multiple advantages for material conveying and mixing. The one-way valve assembly effectively prevents backflow of the base material, resin, and mixed silicone sealant during transport, ensuring stable material delivery in the preset direction. This avoids problems such as imbalanced material mixing ratios, pipe blockages, and chaotic equipment operation caused by backflow, ensuring the orderly progress of the production process. The multi-channel diversion structure of the multiple shower head joints is highly practical. In the base material and resin input stage, it enables decentralized and centralized input, allowing the base material and resin to be centrally transported to a designated location from multiple dispersed inlets, increasing the flexibility of material input and adapting to different feeding methods. In the silicone sealant output stage, it enables centralized and decentralized output, distributing the mixed silicone sealant from a centralized outlet to multiple demand points, meeting different production needs and improving the equipment's applicability. This structural design not only improves the efficiency of material conveying and mixing but also reduces material residue in the pipeline, lowers the difficulty of pipeline cleaning, and facilitates large-scale production and diversified applications of the equipment.

[0024] The beneficial effects of this invention are as follows: The quantitative unit in the servo system precisely controls the delivery volume of the base material and resin, ensuring that they enter the static mixer in the ideal ratio, laying the foundation for high-quality mixing. The static mixer, through its special internal structure, forces the mixture, improving mixing uniformity and ensuring stable product quality. The accumulator connected to the conveying path effectively maintains the continuity and pressure stability of material delivery, ensuring proportioning accuracy and mixing effect. The specialized division of labor design of the hydraulic system improves the targeting and precision of delivery at each stage, reduces mutual interference, and improves the overall operating efficiency and reliability of the equipment. The integrated hydraulic station simplifies pipeline connections, reduces leakage risk, and facilitates installation and maintenance. The rational path design of the pipeline system reduces material residence time and reduces the difficulty of cleaning and maintenance. The second solenoid valve group and flow meter group enable precise monitoring and flexible control of material delivery, reducing manual intervention and improving production efficiency and product quality stability. The configuration of the hydraulic quantitative unit and auxiliary quantitative unit enhances the flexibility and precision of fluid delivery and the equipment's ability to cope with complex working conditions. The coordinated operation of various valves in the first solenoid valve group provides a key guarantee for the stable operation of the hydraulic system. The one-way valve assembly and shower head connector in the piping system ensure unidirectional material flow, enabling both decentralized and centralized input and output, improving conveying and mixing efficiency, and reducing cleaning difficulty. These design features collectively enhance equipment performance and reliability, extend service life, and reduce maintenance costs. Attached Figure Description

[0033] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0034] Please see Figures 1 to 7As shown, this utility model discloses an energy-saving servo motor-driven glass glue mixing device, including a frame 1, a control cabinet 2 mounted on the frame 1, a hydraulic system 3, a piping system 4, a servo system 5, a static mixer 6, and an energy storage device 7. The control cabinet 2 is electrically connected to the hydraulic system 3 and the servo system 5, respectively. All systems, the static mixer 6, and the energy storage device 7 are connected to the piping system 4. The servo system 5 includes a servo pump group 51, a first servo metering unit 52 for metering the base material, and a second servo metering unit 53 for metering the resin. The discharge of each servo metering unit... All ports are connected to the feed end of the static mixer 6 through the pipeline system 4. The servo pump group 51 is connected to the hydraulic system 3, driving the hydraulic system 3 to provide power for the conveying of the base material and resin. The base material and resin are forcibly mixed in the static mixer 6 through its internal structure. The energy storage device 7 is connected to the conveying path of the base material, resin and / or auxiliary solvent in the pipeline system 4. It is used to store part of the base material, resin and / or auxiliary solvent at the peak of the pulse during the pulse conveying process of the servo system 5, and to release the stored base material, resin and / or auxiliary solvent when the servo system 5 is in the pulse interval.

[0035] After the equipment is started, the operator inputs the proportions and total production volume of the base material, resin, and auxiliary solvent through the control cabinet 2. The control cabinet 2 then triggers the coordinated start-up of the servo system 5 and the hydraulic system 3. After receiving the command, the servo pump group 51 operates, drawing hydraulic oil from the oil tank 311 of the hydraulic system 3 and pressurizing it to provide a stable power source for the entire hydraulic circuit. The first servo metering unit 52 and the second servo metering unit 53, according to the set ratio, use their internal precision piston structure to meter the base material and resin respectively. The base material enters the first servo metering unit 52 from the corresponding storage tank through a dedicated pipeline, and the resin enters the second servo metering unit 53 from another storage tank. Under the action of hydraulic power, both are transported to the static mixer 6 along the pipeline system 4. At the same time, the auxiliary solvent enters the transport path through the pipeline system 4 according to the set ratio.

[0036] Because the servo system 5 adopts a pulse delivery mode, when the pulse peak is reached, the pressure inside the pipeline increases, and some base material, resin and auxiliary solvent will be forced into the energy storage device 7 connected to the delivery path for temporary storage; when the servo system 5 is in the pulse interval, the energy storage device 7 automatically releases the stored material to dynamically compensate for flow fluctuations, thereby maintaining the continuity of material delivery and pressure stability in the pipeline system 4, and ensuring that the base material, resin and auxiliary solvent strictly maintain the set ratio accuracy when entering the static mixer 6.

[0037] When the material enters the static mixer 6, its internal spirally arranged blades repeatedly cut, divert, and merge the material, achieving efficient forced mixing without moving parts to form a uniform glass glue mixture. Throughout the process, the control cabinet 2 collects key parameters such as pressure and flow rate of each system in real time through sensors, dynamically adjusting the output power of the servo pump group 51 and the on / off status of pipeline valves to ensure precise coordination of each link and guarantee a stable and controllable mixing process.

[0038] Specifically, the hydraulic system 3 has a hydraulic station 31, a first hydraulic metering unit 32 connected to the hydraulic station 31 for conveying the base material or resin, and a second hydraulic metering unit 33 for conveying the glass glue formed by mixing the two.

[0039] Hydraulic station 31, as the core power source of hydraulic system 3, consists of components such as oil tank 311, oil pump, filter, and cooler, and is responsible for providing clean and appropriately temperatureed hydraulic oil. When the equipment needs to transport base material or resin, control cabinet 2 sends a command to hydraulic station 31, the oil pump starts and pressurizes the hydraulic oil, which then enters the main oil circuit after being filtered by the oil filter. At this time, the solenoid directional valve corresponding to the first hydraulic metering unit 32 is energized, the valve core shifts, allowing high-pressure hydraulic oil to enter the rodless chamber of the first hydraulic metering unit 32, pushing the piston and causing the piston rod to extend. The pusher plate at the front end of the piston rod squeezes the base material or resin storage chamber, causing the material to flow along the pipeline system 4 under pressure. Simultaneously, the hydraulic oil in the rod chamber flows back to oil tank 311 through the return oil circuit, completing one pushing action.

[0040] After the base material and resin are mixed in the static mixer 6 to form glass glue, the control cabinet 2 issues a switching command, and the oil circuit switching valve of the hydraulic station 31 actuates, allowing the high-pressure hydraulic oil to flow into the second hydraulic metering unit 33. Due to the high viscosity of the glass glue, the piston diameter of the second hydraulic metering unit 33 is larger, and the internal sealing structure uses wear-resistant materials. The piston rod's movement speed is also adjusted according to the characteristics of the glass glue, pushing the mixed glass glue along the output pipe to the packaging machine or other downstream equipment through a slow and stable thrust. Throughout the process, the pressure sensor of the hydraulic station 31 monitors the system pressure in real time. When the pressure is abnormal, the overflow valve automatically opens to relieve pressure, ensuring system safety. The operating frequency and stroke of the first hydraulic metering unit 32 and the second hydraulic metering unit 33 are precisely controlled by the control cabinet 2 according to the material flow rate, enabling targeted conveying of different materials at different processing stages.

[0041] Specifically, the hydraulic station 31 includes an oil tank 311, an oil circuit block 312 integrated on the oil tank 311, and a first solenoid valve group 313 disposed on the oil circuit block 312; the servo pump group 51 draws hydraulic oil from the oil tank 311 and pumps it into the oil circuit block 312. After being regulated by the first solenoid valve group 313, the hydraulic oil is delivered to the first hydraulic metering unit 32 and the second hydraulic metering unit 33 respectively to provide them with a power source.

[0042] The oil tank 311 stores rigorously filtered hydraulic oil. Its capacity is designed according to the system flow rate to meet the needs of continuous operation of the equipment for more than 4 hours. An air filter is installed on the top of the oil tank 311 to prevent contaminants from entering, and a drain valve is installed at the bottom for periodic hydraulic oil replacement. The oil manifold block 312 integrated into the oil tank 311 is made by integral forging. The interior is formed by precision drilling to create multiple independent oil passages. Each passage interface is equipped with a standard thread for easy connection to external pipelines, which greatly reduces the number of leakage points compared to traditional pipeline connection methods.

[0043] The servo pump unit 51 is driven by a servo motor, and the motor speed can be steplessly adjusted via the control cabinet 2. When the equipment starts, the servo motor drives the pump shaft to rotate, and the oil pump draws hydraulic oil from the suction port at the bottom of the oil tank 311. After being pressurized by the gear or plunger structure inside the pump body, it is pumped into the inlet of the oil circuit block 312 through the high-pressure oil pipe. The first solenoid valve group 313 is installed on the side of the oil circuit block 312 and consists of multiple solenoid directional valves, check valves, and pressure regulating valves. Each valve controls a branch. When the first hydraulic metering unit 32 needs power, the corresponding solenoid directional valve coil is energized, and the valve core moves under the action of electromagnetic force, connecting the high-pressure oil passage in the oil circuit block 312 with the inlet of the first hydraulic metering unit 32. The hydraulic oil enters the working chamber of the first hydraulic metering unit 32 through this passage. At the same time, the check valve on the return oil passage ensures that the hydraulic oil can only flow in one direction to prevent backflow. When the second hydraulic metering unit 33 is working, another set of solenoid directional valves activates, and high-pressure hydraulic oil is delivered to the second hydraulic metering unit 33 through another channel within the oil circuit block 312. During the delivery process, the pressure sensor on the oil circuit block 312 monitors the oil pressure in real time. If the pressure exceeds the set value, the overflow valve in the first solenoid valve group 313 will automatically open, guiding the excess hydraulic oil back to the oil tank 311 through the return oil circuit, thereby precisely controlling the power supply to each metering unit and ensuring its stable operation according to the set parameters.

[0044] Specifically, the pipeline system 4 has an input end 41 and an output end 42. The input end 41 is connected to the first hydraulic metering unit 32 to input the initial conveying power of the base material or resin, and the output end 42 is connected to the second hydraulic metering unit 33 to output the mixed glass glue. The static mixer 6 is located in the pipeline system 4 between the two hydraulic metering units.

[0045] The piping system 4 is made of corrosion-resistant stainless steel, with its inner wall precision polished to reduce material flow resistance and residue. The input end 41 consists of two branch pipes, connecting to the base material storage tank and the resin storage tank respectively. The ends of the pipes are sealed to the inlet of the first hydraulic metering unit 32 via flanges. When the first hydraulic metering unit 32 operates, the thrust of its internal piston is transmitted to the material in the input end 41 pipe through a push rod, causing the base material and resin to flow along their respective branch pipes under a pressure of 1.5-2.5 MPa. Before entering the main pipe, both materials pass through their respective check valves to prevent backflow.

[0046] The base material and resin flow in parallel within the main pipeline towards the static mixer 6. Due to their different viscosities, a guide plate within the pipeline guides them to form a stable flow pattern. The static mixer 6 is connected in series on the main pipeline between the two hydraulic metering units. Its inlet is connected to the output pipeline of the first hydraulic metering unit 32, and its outlet is connected via a pipeline to the input terminal 41 of the second hydraulic metering unit 33. After the mixed silicone sealant flows out of the static mixer 6, it continues to flow along the pipeline. At this time, the temperature control system on the inner wall of the pipeline starts working, maintaining the temperature of the silicone sealant at 25-30℃ through a heating device to ensure its viscosity stability.

[0047] When the silicone sealant reaches the position of the second hydraulic metering unit 33, the pushing mechanism of the second hydraulic metering unit 33 is activated, applying a thrust of 2.0-3.0 MPa to the silicone sealant through the output end 42, causing the silicone sealant to flow along the output pipe. The output pipe is equipped with a flow regulating valve, which can adjust the output speed according to the needs of downstream equipment. Since the output pressure of the first hydraulic metering unit 32 is greater than the initial pressure of the second hydraulic metering unit 33, the pressure difference between the two pushes the material to flow naturally through the static mixer 6, eliminating the need for an additional power unit, which simplifies the structure and reduces energy consumption.

[0048] Specifically, the servo metering unit includes a support frame 54, a first three-way cylinder 55 fixedly mounted on the support frame 54, and a servo drive assembly 56, an input cylinder assembly 57, and an output cylinder assembly 58 reciprocatingly mounted on the support frame 54. The output ends 42 of the three assemblies are all provided with piston rods, and the reciprocating motion directions of the piston rods of the three assemblies correspond one-to-one with the three guiding directions of the first three-way cylinder 55. The input cylinder assembly 57 is used to input base material or resin, and the output cylinder assembly 58 outputs base material or resin to the static mixer 6. The three assemblies work together to meterly deliver base material or resin.

[0049] The support frame 54 is constructed from high-strength aluminum alloy profiles and is bolted to the equipment frame 1, providing a stable mounting platform for all components. Its surface is anodized, offering excellent wear resistance and corrosion resistance. The first three-way cylinder body 55 is fixed to the center of the support frame 54 by locating pins. It has three mutually perpendicular guide holes corresponding to the X, Y, and Z directions, respectively. Wear-resistant bushings are embedded in the inner walls of these holes to reduce frictional wear during piston rod movement.

[0050] The servo drive assembly 56 is mounted on the X-direction guide rail of the support frame 54 and consists of a servo motor, a ball screw, and a slider. After receiving the pulse signal from the control cabinet 2, the servo motor drives the ball screw to rotate through the coupling, causing the slider to move precisely along the guide rail, which in turn drives the piston rod in the X-direction to extend and retract. Its positioning accuracy can reach ±0.01mm, which is used to precisely control the metering volume of materials. The input cylinder assembly 57 is located in the Y-direction and consists of a pneumatic cylinder and a feed check valve assembly 43. When it is necessary to input base material or resin, the control cabinet 2 controls the pneumatic valve to open, and compressed air enters the rodless chamber of the cylinder, pushing the Y-direction piston rod to extend and opening the feed check valve, so that the material flows from the storage tank into the Y-direction chamber of the first three-way cylinder body 55.

[0051] At this time, the piston rod in the X direction is in the retracted state, providing space for material to enter. When the material reaches the preset amount, the piston rod of the input cylinder assembly 57 retracts, and the feed check valve closes under the action of spring force to prevent material backflow. Subsequently, the servo drive assembly 56 starts, the X-direction piston rod extends, squeezes the material in the cavity, and pushes it to the Z-direction cavity. Then, the Z-direction piston rod of the output cylinder assembly 58 extends under pneumatic action, pushing the metered material out from the first three-way cylinder 55 and conveying it to the static mixer 6 through the discharge pipe. The piston rod movements of the three components are precisely coordinated by the PLC program of the control cabinet 2. The action sequence and stroke are adjusted in real time according to the viscosity and conveying volume of the material to ensure that the material quantity error of each conveying does not exceed 0.5%.

[0052] Specifically, the frame 1 is equipped with a second solenoid valve group 8 and a flow meter group 9 that are electrically connected to the control cabinet 2. The flow meter group 9 is used to monitor the flow signals of the base material and resin in each pipe section of the pipeline system 4 and feed them back to the control cabinet 2. The second solenoid valve group 8 includes multiple solenoid valves, and the two ends of each solenoid valve are connected to the corresponding pipe section and the metering unit respectively to form a fluid passage. Each solenoid valve can independently or collaboratively control the on / off state between the corresponding pipe section and the metering unit according to the flow signal.

[0053] The frame 1 is welded from square steel and coated with anti-rust paint. The second solenoid valve group 8 and the flow meter group 9 are fixed to the side of the frame 1 by brackets for easy observation and maintenance by operators. The flow meter group 9 consists of multiple electromagnetic flow meters, which are installed on the base material conveying pipe section, the resin conveying pipe section, and the mixed glass glue conveying pipe section. The sensor part is in close contact with the inner wall of the pipe. When the material flows through, it cuts the magnetic field generated by the sensor. The flow meter calculates the real-time flow based on the principle of electromagnetic induction and converts the flow signal into a standard 4-20mA electrical signal, which is transmitted to the PLC module of the control cabinet 2 through a shielded cable.

[0054] Control cabinet 2 analyzes and processes the received flow signals, comparing the actual flow rate with the set flow rate. If the actual flow rate of a certain pipe section is lower than the set value, the PLC will issue a command to energize the corresponding solenoid valve. Each solenoid valve in the second solenoid valve group 8 is a two-position two-way structure with a brass body and oil-resistant rubber seals. When the solenoid valve is energized, the valve core moves upward under the action of electromagnetic force, opening the fluid passage and increasing the material flow rate of that pipe section. If the actual flow rate is higher than the set value, the solenoid valve is de-energized, and the valve core resets under the action of spring force, closing part of the passage and reducing the material conveying volume.

[0055] For example, when the base material flow rate is low while the resin flow rate is normal, control cabinet 2 will open the solenoid valve corresponding to the base material pipe section separately to increase the base material delivery rate; if both the base material and resin flow rates deviate from the set values, the opening of the corresponding solenoid valves will be adjusted simultaneously. The solenoid valves communicate via an internal bus and can be coordinated to adjust according to the magnitude of the flow rate deviation, ensuring that the mixing ratio of base material and resin is always maintained within the set range. Furthermore, each solenoid valve is equipped with a manual operating lever, allowing for manual operation to maintain basic equipment operation in the event of a malfunction in the automatic control system.

[0056] Specifically, the hydraulic metering unit includes a support frame 34, a second three-way cylinder 35 mounted on the support frame 34, a two-way rotating shaft 36 passing through the inside of the second three-way cylinder 35, a rotating shaft driver 37 that drives the two-way rotating shaft 36 to rotate, and a hydraulic drive assembly 38 that reciprocates with the second three-way cylinder 35. The two-way rotating shaft 36 has two positively connected liquid holes, and the output end 42 of the hydraulic drive assembly 38 has a piston rod. The reciprocating direction of the piston rod corresponds to one of the guiding directions of the second three-way cylinder 35. The second three-way cylinder 35 is connected to the pipeline system 4 along the other two guiding directions. The rotating shaft driver 37 drives the two-way rotating shaft 36 to rotate to switch the delivery path of the fluid in the second three-way cylinder 35.

[0057] The support frame 34 is made of cast iron and fixed to the ground with anchor bolts. Its top is machined with a precision-machined guide rail surface to ensure the stability of the second three-way cylinder 35 during movement. The second three-way cylinder 35 has a cubic structure with three mutually perpendicular cylindrical cavities inside, designated A, B, and C. The ends of cavities A and B are connected to the piping system 4, while cavity C engages with the hydraulic drive assembly 38. The two-way rotating shaft 36 has a stepped shaft structure, with its middle section passing through the central hole of the second three-way cylinder 35. A mechanical seal is used between the shaft and the cylinder to prevent material leakage. Two mutually perpendicular liquid holes are machined on the shaft, with diameters matching the inner diameters of cavities A and B.

[0058] The shaft drive 37 is a combination of a servo motor and a gearbox. It is connected to one end of the two-way shaft 36 via a coupling, enabling the shaft to rotate precisely from 0 to 90 degrees. The hydraulic drive assembly 38 consists of a hydraulic cylinder and a displacement sensor. The cylinder body is fixed on the support frame 34, and the end of the piston rod extends into the C-direction cavity of the second three-way cylinder body 35, forming a sealed fit with the cavity. The displacement sensor monitors the extension length of the piston rod in real time and sends feedback to the control cabinet 2. When material needs to be transported from pipeline A to pipeline B, the shaft drive 37 rotates the two-way shaft 36, aligning the two liquid holes on the shaft with the A-way and B-way cavities respectively. At this time, the piston rod of the hydraulic drive assembly 38 is in the retracted state, and the material in pipeline A enters pipeline B through the liquid holes under pressure. When the conveying direction needs to be changed to transport material from pipeline B to pipeline A, the shaft drive 37 rotates the two-way shaft 36 90 degrees, realigning the liquid holes. Simultaneously, the piston rod of the hydraulic drive assembly 38 extends, pushing the material in the cavity to flow in the opposite direction. During the material conveying process, the piston rod of the hydraulic drive assembly 38 provides continuous thrust through reciprocating motion. Its speed and stroke are controlled by the control cabinet 2 according to the flow requirements, while the two-way shaft 36 switches the conveying path at any time according to changes in the production process, realizing flexible distribution of materials between different pipelines.

[0059] Specifically, the hydraulic metering unit is equipped with an auxiliary metering unit 39. The auxiliary metering unit 39 includes an auxiliary three-way cylinder 391 mounted on the support frame 34 and an auxiliary drive assembly 392 for reciprocating motion. One guide direction of the auxiliary three-way cylinder 391 corresponds to and cooperates with the auxiliary drive assembly 392. The auxiliary three-way cylinder 391 is connected to the pipeline system 4 along the other two guide directions. Pneumatic ball valves 393 are installed on the two pipe sections of the pipeline system 4 near the auxiliary three-way cylinder 391 along the other two guide directions.

[0060] The auxiliary metering unit 39 shares a support frame 34 with the main hydraulic metering unit and is fixed to the side of the main unit via a connecting plate, maintaining a safe distance between them to avoid mutual interference during operation. The structure of the auxiliary three-way cylinder 391 is similar to that of the second three-way cylinder 35 of the main unit, but smaller in size. Its three internal guiding directions are D, E, and F. The D and E directions are connected to the main pipeline system 4 via branch pipes, while the F direction cooperates with the auxiliary drive assembly 392. The auxiliary drive assembly 392 is a small hydraulic cylinder whose working pressure and flow rate can be independently adjusted. The piston rod forms a sealed fit with the F-direction cavity of the auxiliary three-way cylinder 391, and the volume inside the cavity is changed by extension and retraction.

[0061] A pneumatic ball valve 393 is installed near the D-direction and E-direction interfaces of the auxiliary three-way cylinder 391 in the pipeline system 4. The ball valves are made of stainless steel, and the valve stems are driven by cylinders, enabling rapid opening and closing. Their opening and closing status is controlled by the control cabinet 2 via solenoid valves. When the amount of material conveyed by the main hydraulic metering unit is slightly lower than the set value, the control cabinet 2 issues a command to open the D-direction pneumatic ball valve 393. The piston rod of the auxiliary drive assembly 392 retracts, creating a negative pressure in the D-direction to F-direction chambers of the auxiliary three-way cylinder 391. Some of the material in the main pipeline flows into the auxiliary three-way cylinder 391 through the branch pipe. Subsequently, the D-direction pneumatic ball valve 393 closes, the E-direction pneumatic ball valve 393 opens, the piston rod extends, and the material in the auxiliary cylinder is pushed to the downstream section of the main pipeline to supplement the insufficient conveying capacity of the main unit.

[0062] If the main unit's conveying capacity is slightly high, the E-direction pneumatic ball valve 393 is opened, and the piston rod extends to push the material in the auxiliary cylinder to the upstream of the main pipeline. Alternatively, the D-direction ball valve is opened to retract the piston rod and extract some material, temporarily storing it in the auxiliary cylinder. When the main unit's conveying capacity is accurate, both pneumatic ball valves 393 are closed, the auxiliary three-way cylinder 391 is completely isolated from the pipeline system 4, and the auxiliary drive assembly 392 is also stationary, not affecting the normal operation of the main unit. The movement amplitude of the auxiliary drive assembly 392 is calculated based on the deviation value of the main unit and is fed back in real time by a displacement sensor to ensure precise and controllable adjustment.

[0063] Specifically, the first solenoid valve group 313 includes a solenoid relief valve for regulating the pressure of the hydraulic system 3, a solenoid directional valve for switching the direction of the oil circuit, and an electro-hydraulic directional valve for high flow and high pressure control. The three work together to achieve precise regulation of the pressure, flow direction and flow of the hydraulic system 3, and ensure the power supply of the servo metering unit.

[0064] The first solenoid valve assembly 313 is integrated and mounted on the surface of the manifold block 312, and is tightly fixed to the manifold block 312 with high-strength bolts. The oil inlets and outlets of each valve are interconnected through precision-machined channels inside the manifold block 312, which greatly reduces the layout of external pipelines, lowers the risk of hydraulic oil leakage, and makes the oil circuit layout more compact and easier to maintain. The solenoid relief valve, as the "safety valve" of the system pressure, has core components including a valve body, electromagnet, pressure regulating spring, and conical valve core. The valve body is made of forged steel and has a main oil circuit channel and an overflow channel inside. The oil inlet is directly connected to the main oil circuit, and the oil outlet is connected to the oil tank 311 through a return oil pipe.

[0065] When the hydraulic system 3 pressure is within the normal operating range, the electromagnet is de-energized, and the spring force of the pressure regulating spring presses the valve core tightly against the valve seat, closing the overflow passage and allowing all hydraulic oil to flow into the working oil circuit. When the system pressure exceeds the set value (e.g., due to a sudden pressure increase caused by a change in the load of the servo metering unit), the control cabinet 2 sends an electrical signal to the electromagnet of the electromagnetic relief valve. The electromagnet generates electromagnetic force to attract the valve core, overcoming the spring force and causing the valve core to move upward, opening the overflow passage. Some high-pressure hydraulic oil flows back to the oil tank 311 through the overflow passage until the system pressure drops below the set value. Subsequently, the electromagnet is de-energized, and the valve core resets under the action of the spring force, closing the overflow passage. Its pressure adjustment range can be continuously adjusted between 0.5-31.5MPa via the knob on the top of the valve body to meet the pressure requirements under different working conditions.

[0066] Specifically, the piping system 4 includes a one-way valve assembly 43 and multiple sets of shower head connectors 44. The one-way valve assembly 43 is used to ensure the one-way flow of the base material, resin and the glass glue formed by the mixture of the two. The multiple sets of shower head connectors 44 realize the centralized input of the base material and resin and the centralized output of the glass glue through a multi-channel diversion structure.

[0067] The one-way valve assembly 43 consists of multiple one-way valves, installed at key nodes in the base material conveying pipe, resin conveying pipe, and glass glue output pipe. Each one-way valve has a spring-loaded valve core inside, and the valve core and valve seat adopt a conical sealing structure with wear-resistant ceramic plates embedded in the sealing surface to ensure reliable sealing even under high pressure. When the base material flows in the conveying direction under pressure, the fluid pressure overcomes the spring force to push the valve core open, forming a passage and allowing the base material to pass smoothly. If there is a reverse flow tendency due to pipeline pressure fluctuations, the valve core quickly closes the valve port under the combined action of spring force and reverse pressure, blocking the backflow path and preventing the base material and resin from mixing or flowing back in the pipeline, thus ensuring the unidirectional and orderly conveying of materials.

[0068] The multiple shower head connectors 44 adopt a modular design. The shower head connectors 44 at the input end 41 are equipped with 4-6 dispersed feed ports. Each feed port is connected to a different base material or resin storage tank through a hose. The dispersed input materials are concentrated through an annular confluence chamber. The inner wall of the confluence chamber is machined with a spiral guide groove to make the incoming materials form a rotating flow state, which initially enhances the premixing effect of the base material and resin.

[0069] The shower head connector 44 at the output end 42 has 8-12 dispersed discharge ports, each equipped with an adjustable flow rate throttle valve. The mixed silicone sealant enters the centralized chamber of the output shower head connector 44 through the main pipe, and is then distributed to each discharge port through a multi-channel distribution structure, which can simultaneously meet the needs of multiple packaging stations or adhesive application processes. The shower head connector 44 is made of high-strength engineering plastic with a Teflon coating to reduce material adhesion. Each connector has a quick-release structure for easy regular cleaning and maintenance, ensuring good distribution performance even after long-term use. The one-way valve assembly 43 works in conjunction with the shower head connector 44, ensuring the accuracy of material conveying direction and adapting to different production scales and process requirements through a flexible distribution structure, thereby improving the equipment's versatility and production efficiency.

[0070] The working principle of this utility model is as follows: After startup, the control cabinet 2 acts as the core control center, receiving preset parameters and issuing instructions to each system. The servo pump group 51 of the servo system 5 draws hydraulic oil from the oil tank 311 of the hydraulic station 31, pressurizes it, and pumps it into the oil circuit block 312. Then, through the regulation of the first solenoid valve group 313, the hydraulic oil is precisely distributed to each metering unit of the hydraulic system 3, providing power for the conveying of base material, resin, and mixed glass glue. The base material and resin are quantitatively drawn by the first and second servo metering units according to the set ratio and conveyed through the input end 41 of the pipeline system 4. At the same time, the auxiliary solvent is incorporated into the conveying path through the pipeline system 4 according to the set ratio. During the peak of the pulse conveying of the servo system 5, the energy storage device 7 stores part of the base material, resin, and / or auxiliary solvent and releases it during the pulse interval to maintain the continuity of conveying and pressure stability. Subsequently, the material enters the static mixer 6, where it is forcibly mixed under the action of its special internal structure. After forming glass glue, it flows along the pipeline to the output end 42 and is pushed to the downstream equipment by the second hydraulic metering unit 33.

[0071] During equipment operation, all systems work together to achieve efficient operation. The one-way valve group 43 of the pipeline system 4 ensures unidirectional material flow and prevents backflow; multiple shower head joints 44, through a multi-channel diversion structure, realize the centralized input of base material and resin and the centralized output of glass glue. The hydraulic metering unit and the auxiliary metering unit 39 work together to precisely control the material conveying volume by switching the conveying path with the rotating shaft and the reciprocating motion of the piston rod, meeting the needs of different working conditions.

[0072] The entire process forms a closed-loop control system. Flow meter group 9 monitors the material flow rate in the pipeline in real time and feeds the signal back to control cabinet 2. Control cabinet 2 adjusts the second solenoid valve group 8 based on the feedback to control the on / off of the corresponding pipe section, ensuring accurate material proportions. The first solenoid valve group 313, through the coordinated action of the solenoid relief valve, solenoid directional valve, and electro-hydraulic directional valve, precisely regulates the pressure, flow direction, and flow rate of the hydraulic system 3. The actions of each component are coordinated by control cabinet 2, achieving automated operation and significantly improving the stability and mixing accuracy of the equipment.
