Features and principles of blow molding machines for medical supplies series:

In the production process of blown film, the average thickness of the film is a key indicator. The average thickness in the longitudinal direction can be controlled by the stability of the extrusion and traction speed, while the average thickness in the transverse direction of the film generally depends on the fine manufacturing of the die. , And change with the change of production process parameters. In order to improve the average thickness of the film in the transverse direction, it is necessary to introduce an automatic transverse thickness control system. Commonly used control methods include automatic die head (heat shrink screw control) and automatic air ring. Ring principle and application.

 The basic principle of the blow molding machine: the automatic air ring structure adopts the double air outlet method, in which the air volume of the lower air outlet is kept constant, and the upper air outlet is divided into several air ducts. Each air duct is composed of air chambers, valves, motors, etc. The motor drives the valve to adjust the opening degree of the air duct, and control the air volume of each air duct.


 During the control process, the film thickness signal detected by the thickness measuring probe is sent to the computer. The computer compares the thickness signal with the current set uniform thickness, stops the calculation according to the thickness deviation vector and the curve change trend, and controls the motor to drive the valve to move. When it is thin, the motor moves forward and the tuyere is closed; on the contrary, the motor moves in the reverse direction and the tuyere increases. After changing the air volume at each point on the circumference of the wind ring, adjust the cooling speed of each point to control the lateral thickness of the film within the target range. .
