[0034] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0037] Example 1:

[0038] Please see Figure 1 - Figure 3 This is the first embodiment of the present invention.

[0039] This embodiment provides a mixing device for a dispensing machine, including:

[0040] 1. Material cylinder; 2. Metering mechanism; 3. Plate; 4. Cylinder; 5. Piston rod; 6. Top plate; 7. Tie rod; 8. Scraper; 9. Mixing mechanism; and 10. Conveying mechanism.

[0041] The metering mechanism 2 is located on the top side of the feed cylinder 1;

[0042] The plate 3 is fixed inside the metering mechanism 2;

[0043] Cylinder 4 is fixed to the top side of plate 3;

[0044] The mixing mechanism 9 is located inside the material cylinder 1;

[0045] The material conveying mechanism 10 is located on the bottom side of the material cylinder 1.

[0046] Specifically, the metering mechanism 2 includes a cylinder 21, a feed pipe 22, a boss 23, a limiting platform 24, a baffle 25, a first spring 26, a limiting groove 27, a circular plate 28, and a second spring 29. The cylinder 21 is symmetrically fixed to the top side of the material cylinder 1. The feed pipe 22 is fixed to the bottom circumferential surface of the cylinder 21. A boss 23 is fixed to one end of the inner side of the feed pipe 22. A limiting platform 24 is provided on one side of the boss 23. A baffle 25 is fastened to one side of the limiting platform 24. The baffle 25 and the boss 26 are connected. A first spring 26 is fixedly connected between the cylinder 21 and the cylinder 22. A limiting groove 27 is opened at the bottom of the inner side of the cylinder 21. A circular plate 28 is fastened to the top of the inner side of the limiting groove 27. A second spring 29 is fixedly connected between the circular plate 28 and the bottom of the inner side of the limiting groove 27. A scraper 8 is slidably installed inside the cylinder 21. A pull rod 7 is fixed to the top of the scraper 8. The top of the pull rod 7 passes through the cylinder 4 and is fixed to the top plate 6. A piston rod 5 is fixed at the center of the bottom side of the top plate 6, and the piston rod 5 is slidably installed inside the cylinder 4.

[0047] Furthermore, by using baffle 25, circular plate 28 and spring in combination, the adhesive raw material can flow unidirectionally inside the cylinder 21, thereby realizing the function of quantitatively adding adhesive raw material and improving the processing quality of the dispensing machine.

[0048] In use, the required adhesive material is connected to one end of the feed pipe 22 via a conduit. The cylinder 4 is controlled to extend its inner piston rod 5, thereby causing the top plate 6 to rise. At this time, with the cooperation of the pull rod 7, the scraper 8 moves on the inner side of the cylinder 21. The pressure inside the cylinder 21 decreases, causing the baffle 25 to move and compressing the first spring 26. This causes the boss 23 and the limiting platform 24 to open, allowing the adhesive material to be sucked in through the feed pipe 22 and filling the inner side of the cylinder 21. Then, the cylinder 4 is controlled to retract its inner piston rod 5, similarly causing the scraper 8 to slide downwards on the inner side of the cylinder 21, pushing the adhesive material and causing the circular plate 28 to descend, opening the limiting groove 27. This allows the adhesive material to be transported to the inner side of the material cylinder 1, realizing the function of quantitatively adding adhesive material, thereby accurately controlling the proportion of adhesive material and improving the quality of dispensing.

[0049] In summary, through the structure of the metering mechanism 2, the scrapers 8 on the inner side of the two cylinders 21 are moved by the cylinder 4, thereby driving the glue material to flow unidirectionally inside the cylinder 21 through the feed pipe 22. This allows for precise control of the glue material ratio, ensuring that it is mixed evenly and can be cured normally, thus improving the quality of the dispensing process of the dispensing machine.

[0050] Example 2:

[0051] Please see Figure 4 - Figure 5 This is the second embodiment of the present utility model.

[0052] Specifically, the stirring mechanism 9 includes a support platform 91, a servo motor 92, a small pulley 93, a stirring shaft 94, a spiral blade 95, a stirring rod 96, a large pulley 97, and a belt 98. The support platform 91 is fixed on the top circumferential surface of the material cylinder 1. The servo motor 92 is fixed on the bottom side of the support platform 91. The output end of the servo motor 92 passes through the support platform 91 and is fixed to the small pulley 93. The stirring shaft 94 is rotatably inserted inside the material cylinder 1. The spiral blade 95 is fixed on the circumferential surface of the stirring shaft 94. The stirring rod 96 is fixed on the circumferential surface of the stirring shaft 94. The top end of the stirring shaft 94 passes through the material cylinder 1 and is fixed to the large pulley 97. A belt 98 is fitted on the large pulley 97 and the small pulley 93.

[0053] Furthermore, with the help of the pulley, the stirring shaft 94 is rotated by the servo motor 92, so that the material inside the barrel 1 is stirred by the spiral blade 95 and the stirring rod 96 before the dispensing process, so that it is mixed evenly, thereby improving the quality of the dispensing process.

[0054] Specifically, the material conveying mechanism 10 includes a material conveying pipe 101, a rotating shaft 102, a screw feeder 103, a limiting block 104, a connecting cylinder 105, and an elastic plate 106. The material conveying pipe 101 is fixed at the center of the bottom side of the material cylinder 1. The rotating shaft 102 is rotatably installed inside the material conveying pipe 101. The screw feeder 103 is fixed on the circumferential surface of the rotating shaft 102. The limiting block 104 is fixed at the top of the rotating shaft 102. The connecting cylinder 105 is rotatably fitted on the top side of the limiting block 104. The elastic plate 106 is evenly fixed inside the connecting cylinder 105, and the elastic plate 106 is evenly installed on the side of the limiting block 104. The connecting cylinder 105 is fixed at the bottom end of the stirring shaft 94.

[0055] Furthermore, the screw feeder 103 can quantitatively deliver glue to the outside through the feed pipe 101 when the rotating shaft 102 drives it to rotate, preventing excessive glue from affecting the quality of the dispensing process.

[0056] In use, the servo motor 92 drives the small pulley 93 at the output end to rotate, which, in conjunction with the belt 98 and the large pulley 97, drives the stirring shaft 94 to rotate. At this time, the limit block 104 pushes the elastic plate 106 to bend, preventing the rotating shaft 102 from rotating with the stirring shaft 94 and causing impurities to be mixed into the inner side of the material cylinder 1. The stirring rod 96 on the circumferential surface of the stirring shaft 94 stirs and mixes the material evenly. The spiral blade 95 scrapes off the material adhering to the inner wall of the material cylinder 1 and stirs it to ensure that it is fully mixed. Then, the servo motor 92 is controlled to drive the stirring shaft 94 to rotate forward in the same way. At this time, the elastic plate 106 presses against the side of the limit block 104, thereby driving the limit block 104 to rotate forward with the stirring shaft 94. At this time, the rotating shaft 102 drives the spiral feeder 103 to rotate, and quantitatively outputs glue to the outside through the feed pipe 101, thereby performing the glue dispensing operation.

[0057] In summary, the structure of the mixing mechanism 9 and the conveying mechanism 10 allows the glue to be mixed evenly before being quantitatively output for dispensing, thereby improving the processing quality of the dispensing machine.
