Description

Technical Field

[0001] This utility model relates to the field of EVA hot melt adhesive production technology, and in particular to a mixing tank for EVA hot melt adhesive. Background Technology

[0002] EVA hot melt adhesive is a solvent-free, moisture-free, 100% solid fusible polymer. It is solid at room temperature and melts into a flowable liquid adhesive with a certain viscosity when heated to a certain extent. After melting, it is a light brown semi-transparent or off-white substance. The main component of hot melt adhesive, namely the basic resin, is a copolymer of ethylene and vinyl acetate under high pressure. It is then combined with tackifiers, viscosity modifiers, antioxidants, etc. to make hot melt adhesive. In the hot melt adhesive production process, a mixing tank is required to mix and stir the hot melt adhesive raw materials.

[0003] Chinese Patent Publication No. CN215783152U discloses a hot melt adhesive mixing tank for processing automotive seat back panels, belonging to the field of automotive seat manufacturing technology. It includes a mixing tank shell assembly mounted on a bracket. The mixing tank shell assembly includes a top mixing chamber and a conical mixing chamber rotatably positioned at its bottom. At least three mixing paddle assemblies are evenly rotatably arranged on the bottom side of the top mixing chamber. The output ends of the mixing paddle assemblies are connected to the conical mixing chamber via transmission assemblies. This utility model provides a hot melt adhesive mixing tank for processing automotive seat back panels, which forms multiple vortices in the hot melt adhesive, preventing solidification at the top. Because the transmission assembly can drive the at least three mixing paddle assemblies and the conical mixing chamber to rotate, the helical teeth inside the conical mixing chamber rotate accordingly, causing the upper and lower rotation directions of the hot melt adhesive to differ, thus resulting in more uniform mixing and ensuring the quality of the hot melt adhesive.

[0004] However, most of the aforementioned mixing tanks have a discharge port at the bottom to discharge materials. This method is inefficient and also results in materials adhering to the tank walls, making them difficult to clean and affecting subsequent processing, thus reducing the overall performance.
