220l blue barrel blow molding machine

This is a 50-220L chemical barrel filling machine that can produce three-layer products. After the materials are mixed evenly according to the process requirements, they are input into the hopper (large and small hoppers), and the electric heater switch is closed to heat the barrel (or barrel) and the head and die of the feeding section, compression section, and homogenization section to the specified temperature. The motor is started to slowly increase the speed of the screw from a low speed. The material is heated in the feeding section and moves to the compression section under the push of the screw thread. At this time, the material gradually softens and melts due to the heat. All the materials entering the compression section melt into a viscous object, and then move to the homogenization section to melt and mix at the front end of the screw. After the filter screen and the porous plate are mixed and flowed, they enter the head flow channel of the extruder, and are extruded from the gap between the upper and lower dies to form a tubular parison.
