Description

Technical Field

[0001] This utility model relates to the field of glue dispensing equipment technology, specifically to an online vacuum degassing two-liquid glue dispensing machine. Background Technology

[0002] A two-component glue dispensing machine is a device used for dispensing two-component adhesives. It typically consists of two barrels and two glue pumps, its function being to store the two adhesive components separately and mix them at the dispensing port. The inline vacuum degassing two-component glue dispensing machine builds upon this foundation by adding inline operation and vacuum degassing functions. Inline operation allows for better integration into automated production lines, achieving continuous and efficient glue dispensing; the vacuum degassing function creates a vacuum environment to remove air bubbles from the adhesive, thereby improving dispensing quality.

[0003] Traditional two-component dispensing machines rely heavily on frequent manual loading and unloading, making seamless integration with other automated equipment difficult for large-scale production. This not only increases labor costs but also increases the risk of human error, reducing production efficiency and product yield. Furthermore, the position of the products to be dispensed is easily disturbed during transport, and failure to adjust promptly can affect product quality. Therefore, an online vacuum degassing two-component dispensing machine is proposed to address these issues. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An online vacuum degassing two-component dispensing machine includes a machine body. Two vertical plates are fixedly connected to the upper surface of the machine body. A horizontal plate is fixedly connected to the upper end of the vertical plates. A mixing tank is fixedly connected to the center of the upper surface of the horizontal plate. Several support columns are fixedly connected to the front and rear sides of the mixing tank on the upper surface of the horizontal plate. Material tank 1 and material tank 2 are fixedly connected to the upper ends of the front and rear support columns, respectively. The lower ends of material tank 1 and material tank 2 are connected to conveying pipes. A control valve 1 is installed in the middle of the two conveying pipes. The ends of the two conveying pipes away from material tank 1 and material tank 2 are connected to the interior of the mixing tank.

A dispensing pipe is connected to the lower end of the mixing tank. The other end of the dispensing pipe passes through the upper end of the horizontal plate and extends to the lower side of the horizontal plate. A control valve 2 is installed on the dispensing pipe.

[0007] Preferably, two mounting seats are fixedly connected to the front side of the machine body. A motor is fixedly mounted on the upper surface of the mounting seats. A rotating shaft is fixedly connected to the output end of the motor. The end of the rotating shaft away from the motor is rotatably connected to the front side of the machine body. A semi-spur gear is fixedly connected to the outer surface of the rotating shaft. The semi-spur gear is half toothed and half toothless, and the semi-spur gear meshes with a spur gear.

[0008] Preferably, a laser sensor is fixedly installed on the lower surface of the horizontal plate on the right side of the control valve.

[0009] Preferably, the machine body is provided with a conveyor belt inside, and a number of bases are uniformly fixedly connected to the outer surface of the conveyor belt. The upper surface of the base is provided with a positioning mechanism. The two drive rollers of the conveyor belt pass through the front side of the machine body and are respectively fixedly connected to the rear side of two spur gears.

[0010] Preferably, the positioning mechanism includes two fixed blocks fixedly connected to the upper surface of the base. A forward and reverse motor is fixedly installed on the upper surface of the base in front of the front fixed block. A threaded rod is fixedly connected to the output end of the forward and reverse motor. The threaded rod passes through the front fixed block and is rotatably connected to the rear fixed block. A movable seat is threadedly connected to the outer surface of the threaded rod. A guide rod is fixedly connected between the two fixed blocks. The outer surface of the guide rod is slidably connected to the movable seat.

[0011] Preferably, both the vent valve and the high-efficiency vacuum pump are connected to the interior of the mixing tank.

[0012] Preferably, the output end of the second motor is fixedly connected to a stirring shaft, the stirring shaft passes through the upper end of the top cover and extends into the interior of the mixing tank, and a number of stirring rods are fixedly connected to the outer surface of the stirring shaft.

[0014] Compared with the prior art, this utility model provides an online vacuum degassing two-liquid dispensing machine, which has the following beneficial effects:

[0015] This invention features a positioning mechanism that uses a laser sensor to determine the correct position of the product to be glued. If adjustment is needed, the laser sensor outputs an electrical signal to drive a forward and reverse motor to rotate, which in turn rotates a threaded rod, thus moving the movable seat until the product to be glued reaches the expected position. This improves the accuracy of glue application and ensures product quality.

[0016] This invention utilizes a spur gear-semi-spur gear transmission mechanism. A motor drives the semi-spur gear to rotate. When the semi-spur gear meshes with the spur gear, it provides conveying power, propelling the product to be glued forward. When the semi-spur gear separates from the spur gear, the conveyor belt loses power. The distance between any two adjacent bases is equal to the distance the conveyor belt travels each time. By adjusting the initial position of the bases so that the product's glue-to-be-applied area is directly below the glue-applied head, continuous glue-applied operations can be performed after starting the motor, thus improving production efficiency.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] Reference Figures 1-5As shown, an online vacuum degassing two-component dispensing machine includes a body 1. Two vertical plates 2 are fixedly connected to the upper surface of the body 1. A horizontal plate 5 is fixedly connected to the upper end of the vertical plates 2. A mixing tank 11 is fixedly connected to the center of the upper surface of the horizontal plate 5. Several support columns 6 are fixedly connected to the front and rear sides of the mixing tank 11 on the upper surface of the horizontal plate 5. Material tank 1 7 and material tank 2 8 are fixedly connected to the upper ends of the front and rear support columns 6, respectively. The lower ends of material tank 1 7 and material tank 2 8 are connected to conveying pipes 9. A control valve 10 is installed in the middle of the two conveying pipes 9. The end of the delivery pipe 9 away from material tank 7 and material tank 8 is connected to the interior of the mixing tank 11. The top of the mixing tank 11 is fixedly connected to the top cover 12. The top surface of the top cover 12 is fixedly installed with motor 13, vent valve 14 and high-efficiency vacuum pump 15. Vent valve 14 and high-efficiency vacuum pump 15 are both connected to the interior of the mixing tank 11. High-efficiency vacuum pump 15 is used to suck out the air in the mixing tank 11 and the air bubbles generated during the mixing process, so as to ensure the quality of glue dispensing. Vent valve 14 is used to introduce external air into the mixing tank 11 before glue dispensing, so as to ensure that the glue can flow out normally.

[0027] Furthermore, the output end of motor 13 is fixedly connected to a stirring shaft 16. The stirring shaft 16 passes through the upper end of the top cover 12 and extends into the interior of the mixing tank 11. Several stirring rods 17 are fixedly connected to the outer surface of the stirring shaft 16. When different adhesives enter the mixing tank 11 through the conveying pipe 9, motor 13 is started to fully stir the mixed adhesives, thereby improving the glue dispensing quality.

[0028] Furthermore, two mounting bases 3 are fixedly connected to the front side of the machine body 1. A motor 4 is fixedly mounted on the upper surface of the mounting base 3. A rotating shaft 22 is fixedly connected to the output end of the motor 4. The end of the rotating shaft 22 away from the motor is rotatably connected to the front side of the machine body 1. A semi-spur gear 23 is fixedly connected to the outer surface of the rotating shaft 22. The semi-spur gear 23 is half toothed and half toothless. The semi-spur gear 23 meshes with a spur gear 24. The motor 4 drives the semi-spur gear 23 to rotate. When the semi-spur gear 23 meshes with the spur gear 24, it provides conveying power. When the semi-spur gear 23 separates from the spur gear 24, the conveyor belt 25 loses power. A damping device is provided at the connection between the conveyor belt 25 and the machine body 1. The viscous resistance of the viscous fluid is used to dissipate kinetic energy. After losing power, the conveyor belt 25 can stop immediately.

[0029] Furthermore, a conveyor belt 25 is installed inside the machine body 1. Several bases 26 are uniformly fixedly connected to the outer surface of the conveyor belt 25. A positioning mechanism 27 is provided on the upper surface of the base 26. The distance between two adjacent bases 26 is equal to the distance the conveyor belt 25 moves forward each time. The initial position of the base 26 is adjusted so that the part of the product to be glued is directly below the glue dispensing head 21. After starting the motor 4, continuous glue dispensing operation can be carried out, which improves production efficiency. The two drive rollers of the conveyor belt 25 pass through the front side of the machine body 1 and are respectively fixedly connected to the rear side of the two spur gears 24.

[0030] Furthermore, the positioning mechanism 27 includes two fixing blocks 2701 fixedly connected to the upper surface of the base 26. A forward and reverse motor 2702 is fixedly installed on the upper surface of the base 26 in front of the front fixing block 2701. A threaded rod 2703 is fixedly connected to the output end of the forward and reverse motor 2702. The threaded rod 2703 passes through the front fixing block 2701 and is rotatably connected to the rear fixing block 2701. A movable seat 2704 is threadedly connected to the outer surface of the threaded rod 2703. A guide rod 2705 is fixedly connected between the two fixing blocks 2701. The outer surface of the guide rod 2705 is slidably connected to the movable seat 2704.

[0031] Furthermore, the lower end of the mixing tank 11 is connected to a dispensing pipe 19. The other end of the dispensing pipe 19 passes through the upper end of the horizontal plate 5 and extends to the lower side of the horizontal plate 5. A control valve 28 is installed on the dispensing pipe 19. A laser sensor 28 is fixedly installed on the lower surface of the horizontal plate 5 to the right of the control valve 28. The laser sensor 28 determines whether the position of the product to be dispensed is correct. If adjustment is required, the laser sensor 28 outputs an electrical signal to drive the forward and reverse motor 2702 to rotate, which drives the threaded rod 2703 to rotate, thereby moving the moving seat 2704 until the product to be dispensed reaches the expected position. A flow controller 20 is fixedly installed at the lower end of the dispensing pipe 19. The flow controller 20 is used to control the amount of dispensing each time to adapt to different dispensing needs. A dispensing head 21 is fixedly connected to the lower end of the flow controller 20.

[0032] Working principle: When using this utility model, first adjust the initial position of the base 26 so that the part of the product to be filled with glue is directly below the glue filling head. Then, add different types of glue to material tank 7 and material tank 8. Through the control valve 10, the glue in material tank 7 and material tank 8 enters the mixing tank 11 in proportion. Start the motor 13 to drive the stirring shaft 16 to rotate, thereby driving the stirring rod 17 to rotate, so that the mixed glue can be fully stirred. After the glue is stirred, start the high-efficiency vacuum pump 15 to suck out the air in the mixing tank 11 and the air bubbles generated during the stirring process, so as to ensure the glue filling quality. Before filling, open the vent valve 14 to introduce external air into the mixing tank 11 so that the glue can flow out normally. The product to be glued is placed on the moving seat 2704. The motor 4 is started, which drives the semi-spur gear 23 to rotate. When the semi-spur gear 23 meshes with the spur gear 24, it provides conveying power and moves the product to be glued forward. The laser sensor 28 determines whether the position of the product to be glued is correct. If adjustment is needed, the laser sensor 28 outputs an electrical signal to drive the forward and reverse motor 2702 to rotate, which drives the threaded rod 2703 to rotate, thereby moving the moving seat 2704 until the product to be glued reaches the expected position. When the semi-spur gear 23 separates from the spur gear 24, the conveyor belt 25 loses power. The product to be glued is now located below the glue dispensing head 21. The control valve 18 is opened, and the glue flows into the glue dispensing pipe 19. The glue dispensing volume is controlled by the flow controller 20 to perform the glue dispensing operation. Repeating the steps can realize a streamlined operation and improve production efficiency.
