A bottle blowing machine is a device that blows plastic bottles from preforms formed by plastic crystallization. An important component of the bottle blowing machine is the cylinder, which drives various parts of the machine to complete the blowing process. Each part of the bottle blowing machine requires a bottle blowing cylinder. Below, we will provide a detailed introduction to the cylinder and its function for each part of the bottle blowing machine.

Rotating cylinder of bottle blowing machine

The rotary cylinder is mainly used to drive the gripper to flip the preform from the upper preform structure onto the conveyor belt. Due to its rotating action function, it is called a rotary cylinder. The rotary cylinder in the bottle blowing machine is frequently used. To ensure equipment stability, manufacturers generally use imported brands. Currently, the main brands of rotary cylinders are well-known foreign brands such as SMC in Japan and FESTO in Germany.

Step cylinder of bottle blowing machine

The stepper cylinder in the bottle blowing machine mainly provides power drive for the preform conveyor belt. The conveyor belt unloads the preform from the preform, passes through the heating oven, and finally reaches the mold closing device. After blowing the bottle, it sends the bottle to the discharge port to complete the transmission process.

Bottle blowing machine stretching cylinder

The stretching cylinder is mainly used to provide power for the bottle blowing stretching rod to drive the bottle blowing. The bottle blank is fed into the mold closing device, and the bottle blank is stretched by the stretching rod and blown into a bottle under high pressure.

Summary: The above are the cylinders used in the assembly of blow molding machine equipment. Due to different uses, the requirements for cylinders are also different. Generally, blow molding machine manufacturers will choose the appropriate blow molding machine cylinder based on the structural characteristics of their own blow molding machine design.
