With the wide application of plastic bottles, the stretch blowing machine, as one of the key equipment for the production of plastic bottles, has received more and more attention from enterprises. In the stretch blowing machine, the application of integrated motors is gradually becoming a new trend in the industry.

01. Equipment Introduction

Bottle blowing machine

Bottle blowing machine is a kind of mechanical equipment used to make plastic bottles. It works by feeding pre-heated plastic particles or prefabricated plastic billets into a mold and using a high-pressure air stream to blow the plastic into the shape of a bottle.

Process flow

The working principle of the blowing machine is usually divided into two steps: stretching and blowing. First, plastic particles or billets are heated to a temperature that makes them malleable. These plastic particles, or billets, are then fed into a mold and formed into the shape of the bottle through a process of stretching and blowing.

During the stretching process, the mold stretches the plastic particles or billets into a long, thin tube. Then, during the blowing process, high-pressure air is injected into this tube, causing it to expand and fill the entire mold cavity. When the plastic has cooled and cured, the mold is opened and the finished bottle is removed.

Blow molding machine can produce plastic bottles of various shapes and specifications, including beverage bottles, cosmetics bottles, cleaning supplies bottles, etc. It is widely used in food and beverage, cosmetics, pharmaceuticals, daily chemicals and other packaging industries.

With the continuous improvement of modern automation, modern blow molding machines usually require dozens of stretch blow molding heads at a time, each set of stretch blow molding with N cylinders/motors, but the conventional motor wiring is complicated, and the configuration of the driver + motor occupies a large space, and the types of modern bottle products are diverse, and the operating environment has the possibility of flushing sputtering.

02. Solution

In a stretch blowing machine, the bottle stretching and blowing process requires precise control to ensure the quality and consistency of the product. Through precise position control, the integrated stepper motor can achieve precise control of bottle stretching and blowing, thereby improving product quality and production efficiency.
