Description

Technical Field

[0001] The utility model relates to the technical field of foam board processing, in particular to a raw material mixing device for foam board processing. Background Art

[0002] With the rapid development of my country's economy, the level of my country's industry is also constantly improving, and the use of foam boards in panels is also relatively common. Foam boards are made of expandable polystyrene beads containing volatile liquid foaming agents. They are white objects that are heated and formed in a mold after pre-expansion. They have fine closed-cell structural characteristics and are mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and carving. They are very widely used. In the process of manufacturing foam products, it is necessary to add the prepared raw materials and various auxiliary additives into the mixing box, and then use the mixing equipment to stir the materials in the mixing box. The traditional stirring device will stick the raw materials to the stirring rod and stirring blades during stirring, and the stirring rod and stirring blades are placed in the mixing box and are not easy to clean.

[0003] The announcement number is: CN216609623U, which discloses a stirring device for foam board production, in which the stirring bracket is installed on the rotating rod, which is convenient for disassembly and cleaning. By setting a shielding plate and a shielding sheet, when the lifting device drives the lifting plate to move down, the shielding plate and the shielding sheet cover the box opening to avoid the raw materials from being sprayed out during stirring. When cleaning is required, the lifting plate is driven up by the lifting device so that the lifting plate lifts the stirring bracket, which is convenient for cleaning the box and the stirring bracket. However, when stirring, the stirring device only sets the stirring bracket at the bottom of the rotating rod, so that when stirring, only the raw materials at the bottom of the box can be stirred, which makes it easy to cause uneven mixing of the raw materials during production. When adding materials, the stirring device only adds materials through the feed port, so that when adding materials, the raw materials and various auxiliary materials need to be put in uniform before stirring, which aggravates the uneven mixing condition.

[0004] Based on this, a raw material mixing device for foam board processing is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
