Description

Technical Field

[0001] This utility model relates to the field of plunger valve technology, and in particular to a two-component six-nozzle plunger valve. Background Technology

[0002] The two-component six-nozzle plunger valve is a specialized control device for adhesive coating and dispensing. With its multi-nozzle synchronous output and precise adhesive control, it is widely applicable to scenarios requiring two-component adhesive applications in the assembly of household appliances, consumer electronics, industrial products, and new energy vehicle parts. In practical use, this plunger valve can simultaneously achieve independent delivery and coordinated control of two different adhesive components. Through its built-in plunger structure and valve body sealing design, it effectively avoids cross-contamination and leakage during the delivery of two-component adhesives, ensuring the accuracy of the adhesive mixing ratio. This is a crucial prerequisite for ensuring bonding strength and curing effect.

[0003] Its six independent nozzles can flexibly adjust the spacing and dispensing angle according to the operation requirements, which can achieve uniform coating of large-area workpieces, as well as precise filling of the fine gaps of small precision parts. It is suitable for the glue operation needs of workpieces of different sizes and shapes. The current six-nozzle plunger valve lacks a mixing and dispensing function, which brings multiple drawbacks. Not only will the glue performance fail due to uneven mixing of two-component glue and unstable dispensing volume, but it is also difficult to ensure the consistency of product quality, affecting the yield rate. It also increases the difficulty of operation and the risk of human error, and cannot meet the needs of large-scale glue operation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a two-component six-nozzle plunger valve, which aims to improve the multiple drawbacks of the lack of mixing and metering function in the existing six-nozzle plunger valve. Not only will the glue performance fail due to uneven mixing of two-component glue and unstable glue output, but it will also be difficult to ensure product quality consistency and affect the yield.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a two-component six-nozzle plunger valve, including a connecting frame, a servo motor fixedly connected to the top left side of the connecting frame, a transmission wheel one fixedly connected to the output end of the servo motor, a transmission wheel two rotatably connected to the top of the connecting frame, the outer walls of the transmission wheel two and the transmission wheel one being connected via a pulley, a lead screw fixedly connected to the bottom center of the transmission wheel two, a hollow plate threadedly connected to the outer wall of the lead screw, a sensor fixedly connected to the front center of the hollow plate, and the hollow plate...

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a two-component six-nozzle plunger valve, including a connecting frame 10. A servo motor 4 is fixedly connected to the top left side of the connecting frame 10. A transmission wheel 18 is fixedly connected to the output end of the servo motor 4. A transmission wheel 2 19 is rotatably connected to the top of the connecting frame 10. The outer walls of the transmission wheel 2 19 and the transmission wheel 18 are connected by transmission through the inner side of a pulley 17. A lead screw 14 is fixedly connected to the middle of the bottom end of the transmission wheel 2 19. A hollow plate 6 is threadedly connected to the outer wall of the lead screw 14. A sensor 20 is fixedly connected to the middle of the front side of the hollow plate 6. The front sides of the left and right ends of the hollow plate 6 are slidably connected. The guide rod 15 and the inner bottom of the connecting frame 10 are all fixedly connected to an L-shaped support plate 11. The top of the L-shaped support plate 11 is fixedly connected to a hollow block 21. The top of the hollow block 21 is fixedly connected to a long block 22. The top of the long block 22 is connected to a U-shaped plate 25. The inner side of the long block 22 is fixedly connected to multiple metering tubes 26. The inner side of the metering tubes 26 is slidably connected to a pressing plate 27. The bottom end of the long block 22 is connected to a base plate 29. The bottom of the base plate 29 is connected to a discharge nozzle 30. The bottom end of the discharge nozzle 30 is provided with AB discharge holes 31. The outer wall of the discharge nozzle 30 is threadedly connected to a discharge pipe 9.

[0035] Specifically, a transmission wheel 18 is securely connected to the output end of the servo motor 4 via a stable connection. Simultaneously, a transmission wheel 19 is rotatably connected to the top of the connecting frame 10. The transmission wheel 19 and transmission wheel 18 are connected via the inner side of a pulley 17. When the servo motor 4 operates, power is transmitted to transmission wheel 19 via transmission wheel 18 and pulley 17, causing it to rotate. A lead screw 14 is fixedly connected to the bottom center of transmission wheel 19. As transmission wheel 19 rotates, lead screw 14 rotates synchronously. A hollow plate 6 is threaded onto the outer wall of lead screw 14. During the rotation of lead screw 14, the hollow plate 6... The device moves up and down along the lead screw 14. A sensor 20 is fixedly connected to the middle of the front side of the hollow plate 6. The sensor 20 can change position as the hollow plate 6 moves to sense specific signals. The guide rod 15 serves as a guide and limiter. An L-shaped support plate 11 is fixedly connected to the bottom of the inner side of the connecting frame 10. A hollow block 21 is fixedly connected to the top of the L-shaped support plate 11. An elongated block 22 is further fixedly connected to the top of the hollow block 21. A U-shaped plate 25 is connected to the top of the elongated block 22. Multiple metering tubes 26 are evenly fixedly connected to the inner side of the elongated block 22. These metering tubes 26 can be used to quantitatively distribute materials and control the flow rate.

[0036] Please see the appendix Figure 4 - Appendix Figure 6 A connecting block 3 is fixedly connected to the left side of the connecting frame 10. A slider 1 2 is fixedly connected to the left side of the connecting block 3. A lifting device 1 is provided inside the slider 1 2. A slider 2 7 is fixedly connected to the right side of the connecting frame 10. A limit rod 8 is slidably connected to the inside of the slider 2 7. A sealing ring 16 is fixedly connected to the upper and lower sides of the inside of the quantitative tube 26. A protective shell 5 is fixedly connected to the right side of the servo motor 4.

[0037] Specifically, these connecting blocks 3 serve as a connection, with slider 1 2 further fixedly connected to its left side. A lifting device 1 is carefully installed on its inner side, providing linear lifting power. Sliding slider 2 7's inner side is slidably connected to the limiting rod 8. The limiting rod 8 is typically a straight and rigid rod-shaped structure, providing precise guidance and stable support for the up-and-down movement of slider 2 7, ensuring that the connecting frame 10 does not deviate during its movement on the right side, thus guaranteeing the smoothness and accuracy of the entire device's operation. The sealing ring 16 provides excellent sealing performance; its presence effectively prevents leakage of materials within the metering tube 26 during transportation or storage. Whether liquid or not, it can be reliably sealed inside the metering tube 26, ensuring that the metering tube 26 can accurately complete the quantitative distribution of materials.

[0038] Please see the appendix Figure 7 - Appendix Figure 9Pneumatic valves 28 are provided on both the front and rear sides of the elongated block 22. A horizontal plate 12 is fixedly connected to the top of the hollow plate 6. A blocking block 13 is fixedly connected to the bottom of the guide rod 15. The outer wall of the blocking block 13 is fixedly connected to the upper middle part of the inner side of the connecting frame 10. A circular plug 23 is provided at the middle of the top of the U-shaped plate 25. A sealing plate 24 is fixedly connected to both the front and rear sides of the U-shaped plate 25.

[0039] Specifically, the U-shaped plate 25 serves as a key channel for material flow and storage in the device. A circular plug 23 is installed at the top center of the U-shaped plate 25. The circular plug 23 can be opened or closed as needed to open the top channel of the U-shaped plate 25. Opening the circular plug 23 facilitates operation, while closing the circular plug 23 prevents material leakage. Sealing plates 24 are fixedly connected to both the front and rear sides of the U-shaped plate 25. The sealing plates 24 have good sealing performance and can effectively prevent the exchange between the material inside the U-shaped plate 25 and the external environment, avoiding material contamination and leakage, and ensuring the stable operation of the device and the quality of the material.

[0040] Working principle: When the plunger valve needs to be used, first adjust the connecting block 3 and connecting frame 10 connected to the slider 2 to a suitable position with the lifting device 1. At this time, the servo motor 4 is started by the sensor 20, which drives the transmission wheel 18 and the belt pulley 17 to rotate the transmission wheel 19. At the same time, the screw 14 is driven, and the hollow plate 6 connected to the outer wall moves downward along the outer wall of the guide rod 15. When it contacts the pressing plate 27 inside the elongated block 22, it works by pressing the metering tube 26 to meter different types of glue. The pressure on the pressing plate 27 itself pushes the glue downward along the inner side of the metering tube 26 into the discharge nozzle 30 connected to the bottom plate 29. At this time, the glue is moved into the discharge tube 9 through the AB discharge holes 31 for mixing and dispensing. Therefore, it can effectively mix and dispense the glue inside the plunger valve, reduce the time of manual mixing, and achieve accurate metering. The six nozzles can improve the efficiency of use and meet the needs of daily use.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
