The application relates to a
powder coating extrusion and crushing device, which comprises an extruder, a tabletting mechanism arranged below the output end of the extruder, a conveying mechanism arranged below the tabletting mechanism and conveying tablet materials, a cooling air cover arranged on the conveying mechanism and provided with a fan coil, a guide plate arranged on the inner side of the cooling air cover, the guide plate being arranged in an inclined mode and the lower end of the guide plate being capable of being connected with the conveying mechanism, the tablet materials on the conveying mechanism being capable of falling on the conveying mechanism again after passing through the guide plate, a crushing mechanism arranged below the
tail end of the conveying mechanism, and a splash-proof cover arranged above the crushing mechanism. The tablet materials on the conveying mechanism can be moved to a certain height by the guide plate arranged in an inclined mode and then fall on the conveying mechanism again, so that the tablet materials are broken, the subsequent crushing mechanism is facilitated to process, the crushing efficiency is improved, the splash-proof cover is arranged above the crushing mechanism, dust and fragments are prevented from splashing, and the device is convenient to use.
