Description

Technical Field

[0001] This utility model relates to the field of adhesive defoaming, and in particular to an adhesive defoaming device. Background Technology

[0002] During the production or use of adhesives, bubbles can easily be generated due to stirring, mixing or chemical reactions, which can affect the performance and appearance of the product. In order to ensure the performance and state of the adhesive, it is necessary to defoam the adhesive.

[0003] Chinese utility model patent CN202223561980.1 discloses an adhesive defoaming device, comprising: a barrel body; a discharge pipe at the top of the barrel body; a discharge pipe on one side of the bottom of the barrel body; a rotating shaft located at the center inside the barrel body; a motor mounted on the top of the barrel body, with the output shaft of the motor fixedly connected to the upper end of the rotating shaft; several stirring blades mounted on the outer wall of the rotating shaft; an ultrasonic generator mounted on the inner wall of the top of the barrel body; and a spiral blade located between the rotating shaft and the barrel body, with one side of the spiral blade fixedly connected to the inner wall of the barrel body and the other side having a first baffle. The upper end of the spiral blade is correspondingly positioned below the discharge pipe. This utility model not only defoams the adhesive, improving its quality, but also stirs accumulated adhesive, improving the thoroughness of adhesive mixing.

[0004] However, the aforementioned adhesive defoaming device has an ultrasonic generator installed on the inner wall of the top of the barrel. The ultrasonic generator itself does not come into contact with the adhesive, and the generated ultrasonic waves only come into contact with the upper surface of the adhesive, which is not conducive to defoaming the adhesive.

The end of the first stirring shaft 6 away from the air pump 15 extends into the interior of the outer casing 1. When in use, the adhesive is added into the interior of the outer casing 1, and the motor 4 and the air pump 15 are started. The motor 4 drives the first rotating shaft 5 to rotate, which in turn drives the first stirring shaft 6 to rotate. This allows the first stirring blades 7 on the first stirring shaft 6 to stir the adhesive inside the outer casing 1. The shearing force generated by the high-speed stirring causes the air bubbles in the adhesive to be physically broken during the flow process. At the same time, the first stirring shaft 6 below the first rotating shaft 5 can be replaced to allow for the selection of stirring shafts of different specifications to stir the adhesive. The air pump 15 generates negative pressure inside the outer casing 1, causing the air bubbles in the adhesive to expand and burst under negative pressure, thereby removing the air bubbles from the adhesive.

[0033] A second rotating shaft 8 is movably connected to the lower surface of the upper cover 2. The second rotating shaft 8 can rotate on the lower surface of the upper cover 2. A second stirring shaft 9 is fixedly installed at the bottom of the second rotating shaft 8 through a connecting pin. A second stirring blade 10 is fixedly connected to the outer surface of the second stirring shaft 9, and there are multiple second stirring blades 10. When the second rotating shaft 8 rotates, it will drive the second stirring shaft 9 to rotate, so that the second stirring blades 10 on the second stirring shaft 9 can stir the adhesive inside the outer shell 1. At the same time, the second stirring shaft 9 below the second rotating shaft 8 can be replaced to select stirring shafts of different specifications to stir the adhesive. A driving wheel 11 is fixedly connected to the outer surface of the first rotating shaft 5, and a driven wheel 12 is fixedly connected to the outer surface of the second rotating shaft 8. A connecting belt 13 is installed between the driving wheel 11 and the driven wheel 12. When the first rotating shaft 5 rotates, it will drive the driving wheel 11 to rotate, and through the connecting belt 13, it can drive the driven wheel 12 to rotate, thereby driving the second rotating shaft 8 to rotate.

[0034] The lower surface of the upper cover 2 is fixedly connected to the connecting chamber 3. The driving wheel 11, the driven wheel 12, and the connecting belt 13 are all located inside the connecting chamber 3. The connecting chamber 3 can protect the driving wheel 11, the driven wheel 12, and the connecting belt 13.

[0035] The side wall of the outer shell 1 is fixedly connected to a discharge pipe 14. A control valve is installed inside the discharge pipe 14 to facilitate the discharge of the defoamed adhesive. An inlet 17 is opened on the surface of the outer shell 1. The inlet 17 is connected to the inside of the outer shell 1. A sealing cap 18 is installed inside the inlet 17. The adhesive can be added into the outer shell 1 through the inlet 17 for defoaming treatment.

[0036] Working principle: When in use, the adhesive is added into the shell 1, and the motor 4 and air pump 15 are started. The motor 4 drives the first rotating shaft 5 to rotate, which in turn drives the first stirring shaft 6 to rotate. This allows the first stirring blade 7 on the first stirring shaft 6 to stir the adhesive inside the shell 1. The shearing force generated by the high-speed stirring causes the air bubbles in the adhesive to be physically broken during the flow process. The air pump 15 generates negative pressure inside the shell 1, causing the air bubbles in the adhesive to expand and burst under negative pressure, thereby removing the air bubbles from the adhesive.
