Description

Technical Field

[0001] The utility model relates to the technical field of adhesive production, in particular to a defoaming device for water-based adhesive production. Background Art

[0002] Adhesive: A natural or synthetic, organic or inorganic substance that can connect two or more parts or materials together through interfacial adhesion and cohesion. It is collectively called adhesive, also called bonding agent, and is usually referred to as glue. In short, adhesive is a substance that can combine adherends together through adhesion.

[0003] Among them, the existing patent CN202321775341.7 is an adhesive defoaming device, which starts a rotating motor, and the rotating motor drives the rotating shaft to rotate. When the rotating shaft rotates, it will drive the transmission belt and the defoaming rod to rotate at the same time. Since the other end of the transmission belt is movably connected to the stirring rod, the stirring rod will be driven by the transmission belt to rotate when the rotating shaft rotates, so that the internal stirring blades will stir and mix the water and the defoaming agent. By using a mixing chamber, the operation of workers manually diluting and mixing the defoaming agent can be reduced, which saves time and effort and improves the practicality of the device. When the vacuum pump is turned on, the vacuum pump extracts the air inside the device body through the connecting component to form a vacuum environment inside the device. Under the vacuum environment, the bubbles in the material will float up due to the influence of air pressure, and when the defoaming rod rotates, the spurs on the outside of the defoaming rod will puncture the large-volume bubbles in the material. The use of the vacuum pump in combination with the defoaming rod can quickly eliminate the bubbles in the material, thereby improving the working efficiency of the device.

[0004] However, the above-mentioned defoaming device has a low stirring efficiency and requires a long time to stir the adhesive. During the stirring process of the adhesive, due to the lack of a cleaning mechanism inside the defoaming device, a large amount of adhesive remains on the inner wall of the defoaming device after the defoaming device is processed, which is inconvenient to clean. Therefore, it does not meet the existing needs. In this regard, we propose a defoaming device for the production of water-based adhesives. Utility Model Content
