When the molten plastic material flows through the tapping head 6, the length of the control rod 9 extending into the first tapping pipe 61 can be controlled by controlling the position of the stop collar 91 on the control rod 9. When the control rod 9 is pulled outward, the control ball is pulled toward the cylinder 4, so the flow area at the first discharge pipe 61 and the second discharge pipe 62 is increased, and the space from the discharge head 6 is increased and the pressure is decreased under the condition that the feeding speed is not changed, so the outflow speed of the molten plastic is decreased. When the control rod 9 is pushed inward, the control ball is pushed away from the cylinder 4, so that the flow area at the first outlet pipe 61 and the second outlet pipe 62 is reduced, and the space from the outlet head 6 is reduced and the pressure is increased at a constant feed rate, so that the outflow rate of the molten plastic is increased. By controlling the outflow rate of the molten plastic, the size of the package produced can be controlled. After production is finished, air is blown into the barrel body 4, meanwhile, the control rod 9 is controlled to move the adjusting ball 5 for multiple times, so that the plastic in the barrel body 4 can be blown out and cleaned, the cooling and adhesion of the plastic at the discharging machine head 6 are reduced, and the phenomenon that the use of the extruder is influenced due to too much accumulated plastic is prevented. In the extrusion process, the first heater 72 in the rotating shaft 7 and the second heater 8 on the outer wall of the cylinder 4 simultaneously heat the plastic in the cylinder 4, so that the plastic is melted more comprehensively and rapidly, and the production efficiency is effectively improved.
Furthermore, the control rod 9 is provided with scale marks 92. The graduation marks 92 reflect the length of the control rod 9 extending into the first outlet pipe 61, i.e. the position of the adjusting ball 5, and the graduation marks 92 can be used as a reference for an operator to control the position of the adjusting ball 5.
Further, the driving motor 2 is connected with the rotating shaft 7 through a reduction gearbox 3; the reduction gearbox 3 plays a role in controlling the rotating speed of the rotating shaft 7.
