[0033] The above-mentioned flow distribution mechanism includes a flow distribution head shell 6 and a flow distribution head. The flow distribution head shell 6 is outwardly expanded from top to bottom as a whole. The inner wall of the outwardly expanded structure is a smooth wall without zigzag structure, which helps to reduce the contact area between the strip 28 and the inner wall of the flow distribution head shell 6 under high temperature condition, and reduces the possibility of bonding. Especially when working under high temperature condition, the outwardly expanded structure can reduce the bonding between the strip 28 and the flow distribution head shell 6, thereby reducing the probability of the material adhering to the inner wall of the flow distribution head shell 6, so as to facilitate the cleaning of the flow distribution head shell 6 in the later stage and ensure the cleaning effect.

The flow distribution head, the flow distribution head shell 6 and the discharge mechanism are also provided with heating elements for heating the material, which can ensure the flowability of the material during discharging and prevent the material from solidifying during cleaning. The heating element can be a heating sheet or a heating wire or other structure, which is mainly used to heat the material to ensure uniform flow of the material in the flow distribution head and the flow distribution head shell and avoid uneven flow caused by uneven temperature. The material, especially the plastic melt, needs to maintain a certain temperature during the extrusion process to ensure its flowability and plasticizing effect. The heating element can provide continuous external heat to heat the polymer melt from solid state to molten state, maintain the appropriate processing temperature, and thus ensure the quality of the subsequent production.
