[0002] At present, the blow molding equipment on the market has extruders and right-angle heads that play the main role in blow molding, which are located at a relatively high position. When feeding the raw materials into the extruder, it is necessary to climb a very high ladder, which wastes time and manpower, and poses a hidden danger to life safety. In addition, there is a problem of uneven distribution of raw materials when the raw materials enter the extruders on the market, resulting in poor quality of the finished film.

By setting the stirring motor and the stirring body, the raw materials are stirred in the process of feeding into the extruder, and the raw materials can be evenly fed into the extruder, so as to achieve the effect of uniform feeding. By setting the screw and the moving rod, the material basin can be raised from the bottom surface height to the higher extruder height, and there is no need to manually climb up to feed the material, which saves manpower, thereby achieving the effect of semi-automatic feeding. By setting the evaporator and the refrigeration compressor, the air cooling method is changed to water cooling, so that the high-temperature film and the low-temperature evaporator are heat exchanged through the air, and the cooling rate is accelerated, thereby achieving the effect of enhanced cooling.
