Description

Technical Field

[0001] This utility model belongs to the field of adhesive production technology, and in particular relates to a dual planetary high-speed power mixer for the production of OLED display encapsulation adhesive. Background Technology

[0002] Adhesive production is the process of processing natural or synthetic materials into adhesives through specific processes. Modern adhesives mostly use high molecular compounds such as polyvinyl alcohol, white glue, and ethylene glycol, while some special adhesives use ethyl cyanoacrylate as the main component. Current adhesive production combines polymer chemistry, using chemical reactions such as polymerization and cross-linking to improve performance.

[0003] The existing utility model with authorization announcement number CN219482485U discloses a mixing device for producing glue, including a frame, a mixing tank at the front end of the frame, a base slidably connected to the lower end of the frame, a groove on the upper surface of the base, an electric cylinder fixedly installed on the back of the frame, a connecting plate fixedly connected to the front end of the frame, a drive motor fixedly installed above the connecting plate, and a connecting cylinder fixedly connected to the central shaft of the drive motor.

[0004] The above technical solution uses a frame and base to form a vertically extendable fixed structure, which allows for the opening and closing of the mixing drum and cover plate. It also provides sufficient space for disassembly and assembly, facilitating the independent disassembly and assembly of the mixing drum and cover plate. Since the stirring rod is located on the cover plate, the mixing drum and stirring rod can be disassembled for cleaning, improving the convenience of maintenance and cleaning of the mixing device. However, the above technical solution only facilitates cleaning of the mixing drum, and the efficiency of stirring with only a single motor is low, resulting in poor mixing quality and potentially reducing glue production efficiency.

[0005] To address these issues, we propose a dual planetary high-speed power mixer for OLED display encapsulation adhesive production. Utility Model Content

[0006] The purpose of this invention is to solve the problems in the existing technology, which only allows for easy cleaning of the mixing drum and has low efficiency and poor mixing quality due to the use of a single motor for mixing, which easily leads to a decrease in glue production efficiency. Therefore, this invention proposes a dual planetary high-speed power mixer for OLED display encapsulation glue production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-speed dual planetary power mixer for producing OLED display encapsulating adhesive includes a base plate. A control panel and two fixed brackets are fixedly connected to the upper surface of the base plate. Each of the two fixed brackets has a groove on one side facing each other. A hydraulic telescopic rod is fixedly connected to the inner wall of each groove. A sliding plate is fixedly connected to the telescopic end of each hydraulic telescopic rod. A cover plate is fixedly connected to the bottom surfaces of the two sliding plates. Two short bearings are fixedly connected to the inner wall of the cover plate. A long bearing is fixedly connected to the inner ring of one short bearing, and a rotating rod is fixedly connected to the inner ring of the other short bearing. The outer surface of the rotating rod and the long bearing... Gears are fixedly connected to the outer surfaces of the two gears, and the outer surfaces of the two gears mesh with each other. A stirring frame is fixedly connected to the outer surface of the long bearing. A first stepper motor and a second stepper motor are fixedly connected to the top of the cover plate. A stirring rod is fixedly connected to the output end of the first stepper motor. The outer surface of the stirring rod is fixedly connected to the inner ring of the long bearing. The output end of the second stepper motor is fixedly connected to the top of the rotating rod. A sealing airbag is fixedly connected to the inner wall of the cover plate. A fixing ring is fixedly connected to one side of the two fixing frames that are close to each other. A mixing tank is fixedly connected to the inner wall of the fixing ring. A discharge valve is fixedly connected to the bottom of the mixing tank.

[0009] Preferably, each of the two fixed frames has a support plate fixedly connected to one of its opposite sides, and the bottom surface of each support plate is fixedly connected to the upper surface of the base plate.

[0010] Preferably, a protective seat is fixedly connected to the outer surface of each hydraulic telescopic rod, and the bottom surface of each protective seat is fixedly connected to the inner wall of the slide groove.

[0011] Preferably, a reinforcing plate is fixedly connected to the outer surface of the telescopic end of each hydraulic telescopic rod, and the upper surface of each reinforcing plate is fixedly connected to the bottom surface of the sliding plate.

[0012] Preferably, each of the reinforcing plates has four limit bolts threaded to its inner wall, and the outer surface of each set of limit bolts is threaded to the inner wall of the sliding plate.

[0013] Preferably, a reinforcing frame is fixedly connected to the outer surface of each sliding plate, and the bottom surface of each reinforcing frame is fixedly connected to the top surface of the cover plate.

[0014] Preferably, each of the reinforcing frames has two threaded fixing bolts on its inner wall, and the outer surface of each set of fixing bolts is threaded to the inner wall of the cover plate.

[0015] Preferably, the outer surfaces of the first stepper motor and the second stepper motor are fixedly connected to a protective box. The bottom surface of the protective box is fixedly connected to the top surface of the cover plate. The bottom surface of the base plate is fixedly connected to four support feet. The outer surface of each set of support feet is fixedly connected to two limiting rings. The top surface of each set of limiting rings is fixedly connected to the bottom surface of the base plate.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] 1. By setting up a dual stepper motor collaborative drive + planetary stirring structure, efficient and uniform mixing of adhesive raw materials is achieved. The first stepper motor directly drives the stirring rod to rotate, and the second stepper motor drives the gear transmission through the rotating rod, so that the long bearing and the outer stirring frame rotate synchronously with the gear meshing, forming a dual-power stirring system of "stirring rod + stirring frame". This structure can simulate the trajectory of planetary motion, allowing the stirring components to form a multi-directional and multi-speed composite stirring action in the mixing tank, effectively eliminating mixing dead corners, ensuring that the polymer raw materials required for OLED encapsulation adhesive are fully fused, greatly improving the mixing uniformity, improving adhesive production efficiency, and avoiding performance defects of encapsulation adhesive caused by uneven mixing;

[0018] 2. By setting a sealing airbag fixed to the inner wall of the cover plate, when the cover plate is driven by the hydraulic telescopic rod to descend and close the mixing tank, it can closely fit the top edge of the mixing tank to form a flexible sealing structure. This sealing method can not only prevent the glue from splashing due to high-speed rotation during the mixing process, reducing material waste, but also prevent external dust and impurities from entering the mixing tank and contaminating the glue. At the same time, it can prevent the leakage of volatile components of the glue from affecting the production environment, ensuring the purity of the encapsulated glue and the safety of production operations.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-6 A dual planetary high-speed power mixer for producing OLED display encapsulation adhesive includes a base plate 1. A control panel 6 and two fixed frames 2 are fixedly connected to the upper surface of the base plate 1. Each fixed frame 2 has a groove 3 on its side that is close to each other. A hydraulic telescopic rod 15 is fixedly connected to the inner wall of each groove 3. A support plate 5 is fixedly connected to the side that is far from each other of the two fixed frames 2. The bottom surface of each support plate 5 is fixedly connected to the upper surface of the base plate 1. The support plate 5 can fix and support the fixed frame 2 to prevent it from shifting its position during use.

[0028] Each hydraulic telescopic rod 15 has a sliding plate 8 fixedly connected to its telescopic end. The bottom surfaces of the two sliding plates 8 are fixedly connected to a cover plate 13. The inner wall of the cover plate 13 is fixedly connected to two short bearings 19. The outer surface of each hydraulic telescopic rod 15 is fixedly connected to a protective seat 14. The bottom surface of each protective seat 14 is fixedly connected to the inner wall of the slide groove 3. The protective seat 14 can protect the hydraulic telescopic rod 15 and prevent it from being damaged by external forces during use.

[0029] One of the short bearings 19 has a long bearing 22 fixedly connected to its inner ring, and another short bearing 19 has a rotating rod 23 fixedly connected to its inner ring. Gears 21 are fixedly connected to the outer surfaces of the rotating rod 23 and the long bearing 22. A reinforcing plate 16 is fixedly connected to the outer surface of the telescopic end of each hydraulic telescopic rod 15. The upper surface of each reinforcing plate 16 is fixedly connected to the bottom surface of the sliding plate 8. The reinforcing plate 16 can reinforce the hydraulic telescopic rod 15 and the sliding plate 8 to prevent them from swaying or shaking during use.

[0030] The outer surfaces of the two gears 21 mesh with each other, the outer surface of the long bearing 22 is fixedly connected to the stirring frame 24, the top of the cover plate 13 is fixedly connected to the first stepper motor 11 and the second stepper motor 12, and the inner wall of each reinforcing plate 16 is threaded with four limiting bolts 18. The outer surface of each set of limiting bolts 18 is threaded to the inner wall of the sliding plate 8. The position of the reinforcing plate 16 can be restricted by the limiting bolts 18, which can play a role in fixing and limiting.

[0031] The output end of the first stepper motor 11 is fixedly connected to a stirring rod 20. The outer surface of the stirring rod 20 is fixedly connected to the inner ring of the long bearing 22. The output end of the second stepper motor 12 is fixedly connected to the top end of the rotating rod 23. A reinforcing frame 9 is fixedly connected to the outer surface of each sliding plate 8. The bottom surface of each reinforcing frame 9 is fixedly connected to the top end of the cover plate 13. The reinforcing frame 9 can fix the sliding plate 8 and the cover plate 13, thereby enhancing the stability of the device.

[0032] A sealing airbag 17 is fixedly connected to the inner wall of the cover plate 13. A fixing ring 7 is fixedly connected to the side of the two fixing frames 2 that are close to each other. Two fixing bolts 10 are threadedly connected to the inner wall of each reinforcing frame 9. The outer surface of each set of fixing bolts 10 is threadedly connected to the inner wall of the cover plate 13. The fixing bolts 10 can further reinforce the position of the cover plate 13 and prevent it from shaking or shifting during use.

[0033] A mixing tank 28 is fixedly connected to the inner wall of the fixing ring 7. A discharge valve 25 is fixedly connected to the bottom end of the mixing tank 28. A protective box 4 is fixedly connected to the outer surfaces of the first stepper motor 11 and the second stepper motor 12. The bottom surface of the protective box 4 is fixedly connected to the top surface of the cover plate 13. Four support feet 26 are fixedly connected to the bottom surface of the base plate 1. Two limit rings 27 are fixedly connected to the outer surface of each set of support feet 26. The top of each set of limit rings 27 is fixedly connected to the bottom surface of the base plate 1. The protective box 4 can protect the first stepper motor 11 and the second stepper motor 12 from external interference during use. The support feet 26 and limit rings 27 can provide stable support for the entire device.

[0034] The working principle of this utility model is as follows: In use, firstly, a "stretch" command is sent to the two hydraulic telescopic rods 15 via the control panel 6. This causes the telescopic ends of the hydraulic telescopic rods 15 to slide the sliding plate 8 upwards along the slide groove 3. The cover plate 13 rises synchronously with the sliding plate 8 until the top opening of the mixing tank 28 is fully exposed. According to the formulation requirements of the OLED display encapsulating adhesive, each raw material is weighed in proportion and poured sequentially into the mixing tank 28, which is fixed and limited by the fixing ring 7. During the addition of raw materials, it is necessary to avoid spilling raw materials onto the edge of the opening of the mixing tank 28 to prevent the cover plate 13 from closing later. If the sealing airbag 17 is contaminated at the right time, it may cause the raw material to solidify and affect the sealing effect. After the raw material is added, the control panel 6 sends a "lower cover plate 13" command to cause the hydraulic telescopic rod 15 to retract synchronously, driving the sliding plate 8 and the cover plate 13 to move downward along the slide groove 3 until the cover plate 13 completely covers the top opening of the mixing tank 28. At this time, the sealing airbag 17 on the inner wall of the cover plate 13 is tightly fitted with the edge of the opening of the mixing tank 28, which not only prevents the glue from splashing due to high speed rotation during subsequent mixing, but also blocks external dust and impurities from entering the tank, and avoids leakage of volatile components of the glue.

[0035] Next, a "stirring start" command is sent through the control panel 6 to start the first stepper motor 11 and the second stepper motor 12 synchronously. The output end of the first stepper motor 11 directly drives the stirring rod 20 to rotate. The stirring rod 20 is fixed by the inner ring of the long bearing 22. Therefore, the stirring rod 20 rotates at high speed along its own axis to stir the raw materials in the central area of ​​the mixing tank 28. The output end of the second stepper motor 12 drives the rotating rod 23 to rotate. The gear 21 on the outer surface of the rotating rod 23 meshes with the gear 21 on the outer surface of the long bearing 22. Therefore, the long bearing 22 rotates synchronously with the rotating rod 23 under the transmission of the gear 21. Since the outer ring of the long bearing 22 is fixed to the stirring frame 24, the stirring frame 24 moves in a circle around the axis of the rotating rod 23 with the long bearing 22. At the same time, the stirring frame 24 rotates on its own axis with the rotation of the long bearing 22, ensuring that the polymer raw materials required for OLED encapsulation adhesive are fully fused, avoiding problems such as inconsistent adhesive viscosity and encapsulation performance defects caused by uneven mixing.
