The invention relates to the technical field of plastic extruders, and discloses a
formaldehyde-free hot-melt edge sealing
adhesive waste modification and recycling plastic extruder which comprises a base, a spiral conveying mechanism is arranged on the upper portion of the base, a propelling
assembly is arranged at the
tail of the spiral conveying mechanism, and a driving
assembly is arranged in the middle of the propelling
assembly. A feeding assembly is arranged on the upper portion of the propelling assembly, a pressing assembly is arranged in the propelling assembly, the propelling assembly comprises a box fixedly connected to the
tail of the spiral conveying mechanism, an
extrusion opening is formed in the front end of the box, the driving assembly comprises an outer ring fixedly connected to the interior of the box, and a
material distribution barrel is rotationally connected to the interior of the outer ring. According to the
material distribution device, the
material distribution barrel is arranged to be matched with meshing transmission of the driving wheel and the full
bevel gear, intermittent 90-degree rotation of the material distribution
barrel is achieved, the material distribution barrel divides continuously conveyed melt into multiple batches of materials, dispersion treatment of waste melt is achieved, the contact area of a modifier and the waste melt is increased, and mixing uniformity is improved.
