も過言ではない。Temperature condition 1↑ of the chemical foaming extruder has an extremely narrow foaming temperature range due to the characteristics of the extruded material, and it is no exaggeration to say that the temperature that stabilizes the degree of foaming within that temperature range is narrow and only one point. .

でいた。In addition, in the control method, in the case of foaming control, differential control of foaming is performed by moving the cooling water tank at the outlet of the extruder crosshead, and integral control is performed by the cylinder exit temperature (cylinder zone temperature near the crosshead). ). Here, the conventional cooling humidity control is PID control, but since a fan motor is used to make it an inexpensive cooling method, the output under PID control is -. By simply changing the ratio, the maximum air volume is always supplied to the heated object, and at this moment, the foaming strip is ready! 1 collapsed easily, and the stability of foaming was disrupted.

それのメンテナンスが容易でないという問題がある。In addition, as is known in general extruders, the temperature rise due to cooling heat that occurs between the screw and the extruded material deteriorates temperature control. In addition, a method for removing the frictional heat must be used in conjunction with precise temperature control. On the other hand, a method of cooling the outside of the cylinder using heat medium (heat W < oil or water, etc.) has also been used in the past, but in this case, it is equivalent to varying the amount of heat from 0 to 100%. However, there is a problem in that the heat transfer device, the roll valve, etc. that control the amount of heat transfer medium are expensive. In addition, since a heat medium such as water or oil is used,
The problem is that it is not easy to maintain.

Since the stability of the outlet temperature of the cylinder 8 is very uniform, and other cylinder zones also affect the foaming stability, the fan drive motor 1 is placed in each block of the cylinder 8. The PIDID control temperature controller for the motor rotation speed control device 2 for the fan drive motor 1 on the side of the crosshead 9 inputs the temperature sensor 4 built into the extruder and the output of the foaming control device 5.
