Background
In the prior art, a plastic granulator, a plastic recycling machine, an injection molding machine, a blow molding machine, an extruding machine and a plastic mixing mill generally adopt a design that an electric furnace wire heating ring is arranged on a machine pipe of a screw rod for heating. This design presents several problems in use: firstly, the electric energy is wasted because the excircle of the heating ring of the electric furnace wire and the excircle of part of the machine pipe are exposed, so that part of heat energy is dissipated and wasted in space. Secondly, the plastifying is slow, because the design can only heat and plastify the plastics through the hole wall of the machine pipe, the plastifying of the plastics close to the hole wall in the machine pipe is fast and sufficient, and the plastifying of the plastics far away from the hole wall is slow and insufficient, in order to solve the technical problem, two plastic granulators are usually adopted for connecting the plastic granulator and the plastic extruding machine, and the plastified cooked plastics are homogenized and plastified again. This type of connector is called a master-slave type, i.e., one master slave is often manufactured. And thirdly, the plastic flow rate is slow and the production efficiency is low, because the design only depends on the heating and plasticizing of the inner hole wall of the machine pipe, and the plastic plasticizing far away from the inner hole wall of the machine pipe is insufficient.
