Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, specifically to a defoaming device for adhesive production. Background Technology

[0002] Adhesive is a common type of adhesive widely used in various fields. During the adhesive production process, bubbles are generated due to the reaction. The presence of these bubbles affects the quality of the adhesive and subsequent processes, necessitating defoaming treatment.

[0003] A defoaming device for glue production disclosed in announcement number CN222657844U, although the glue is stirred in the tank, the vacuum pump continuously extracts the air bubbles in the glue in the tank through the connecting pipe. Larger air bubbles are blocked by the bubble-blocking plate on the stirring shaft, and smaller air bubbles are defoamed by the defoaming plate in the connecting pipe. By setting the bubble-blocking plate and the defoaming plate to defoam, the probability of the air bubbles bringing glue with them and clogging the pipe is effectively reduced.

[0004] However, the defoaming device used in the production of this adhesive defoams by stirring the shaft, which easily breaks the bubbles into smaller bubbles, affecting the efficiency of bubble elimination. In addition, when the ambient temperature is low, the fluidity of the adhesive decreases, affecting the rise of the bubbles. Utility Model Content
