Description

TECHNICAL FIELD

[0001] The utility model relates to the field of flame retardant processing technology, especially to controllable temperature stirring device of hot melt adhesive flame retardant. BACKGROUND

[0002] The hot melt adhesive flame retardant is a chemical additive capable of preventing hot melt adhesive material from burning. Adding the flame retardant in the hot melt adhesive can make the hot melt adhesive difficult to ignite when encountering open flame, or easy to extinguish and not easy to spread after ignition, thereby significantly improving the safety and quality of the hot melt adhesive product. Through temperature control stirring, the optimal dispersion state and chemical reaction rate of the flame retardant in the hot melt adhesive can be ensured, thereby optimizing the flame retardant performance. Appropriate temperature and stirring conditions can also reduce the loss and degradation of the flame retardant during preparation, further improving the flame retardation effect.

[0003] Through retrieval, the patent with the publication number CN218422228U discloses a controllable temperature stirring device. The stirring blade of the currently used stirring device is usually welded on the outside of the rotating shaft, cannot be flexibly detached, is very inconvenient to clean and maintain, and does not have a temperature adjusting function, so it cannot accurately control the temperature. Therefore, the controllable temperature stirring device is provided with a rotating shaft, a screw hole, a stirring blade, a threaded joint, and a nut. When in use, the stirring motor is started, the rotating shaft is driven to rotate by the stirring motor, and the stirring blades on both sides of the rotating shaft will stir and mix the materials. When the stirring blades need to be cleaned and maintained, the nut is only turned to make the threaded joint rotate and exit from the inside of the screw hole, so that the stirring blades can be detached from the rotating shaft. In this way, the stirring blades can be flexibly detached, and the cleaning and maintenance are very convenient. This solves the problem that the stirring blades cannot be flexibly detached and are very inconvenient to clean and maintain.

[0004] The above controllable temperature stirring device facilitates the flexible detachment of the stirring blades. However, the existing controllable temperature stirring device usually utilizes a rotating rod to drive a single stirring frame to rotate when stirring, so that the hot melt adhesive flame retardant is stirred in the same direction inside. This reduces the uniformity of the hot melt adhesive flame retardant when being stirred, making it difficult to be fully stirred. In addition, a large amount of material will adhere to the barrel wall during stirring, and the stirring frame cannot scrape off the material during stirring, so that a part of the hot melt adhesive flame retardant is excessively heated, thereby reducing the stirring quality.
