Supply semi-automatic bottle blowing machine with automatic system human-machine interface, simple and convenient operation, low failure rate, and fast bottle blowing speed. Reasonable selection of mechanical materials, precise processing and manufacturing, strict control of assembly procedures, fully ensuring the smooth operation of the machine. Fast heating speed, uniform heating, energy-saving. Hydraulic locking mechanism, with strong locking and stable and reliable operation. High quality imported chains are selected for the heating box, with strong durability and stable operation. A good bottle mouth heating system ensures that the bottle mouth is not easily deformed. It adopts a servo motor and electric positioning system imported from Festo, Germany, which can transport bottle preforms quickly and achieve high repeat positioning accuracy, overcoming the shortcomings of traditional pneumatic transport mechanisms. The servo motor stretches the preform, with fast stretching speed, accurate stretching stroke, and adjustable stretching stroke. Hydraulic locking mechanism, with strong locking and stable and reliable operation. The long-term use of the modified machine in combination with filling equipment has improved the fully automatic seamless connection of the assembly line. Security program settings ensure the safety of operators' lives.
