Temperature issues in bottle blowing machines during production
The temperature issue of the bottle blowing machine during production has always been a concern for us, but if we cannot master the skills and methods well, it will affect our later use. Therefore, we might as well do the right job. Then let's make a brief analysis.
(1) Melting temperature TM: For crystalline polymers, it refers to the temperature at which the three-dimensional long-range ordered state of the macromolecular chain structure transforms into a disordered viscous flow state, also known as the melting point. It is the lower limit of the molding processing temperature of crystalline polymers.

Interpretation of the stretching mechanism of the fully automatic bottle blowing machine
The stretching part of the bottle blowing equipment is installed inside the machine, and its direct acting parts are stretching rods arranged at equal intervals. In the original state, the stretching rods are below the fixed head shaft of the bottle preform and are aligned with the mold cavity. During the bottle blowing process, the stretching rods are stretched quickly, enter the bottle preform through the hole in the bottle preform head shaft, and then push the top of the bottle preform upward to help the bottle preform expand and form evenly under the action of high-pressure air. Based on process requirements, the stretching rods are required to move quickly, position accurately, and have low noise and vibration. And the stroke and speed can be adjusted according to the needs of different bottle types.

A bottle blowing machine is a device that uses a blow molding process to make plastic particles into hollow containers. There are two common types at present. One is a semi-automatic bottle blowing machine that uses PP and PE to form a hollow extrusion blow machine in one step, and the other is a fully automatic bottle blowing machine that uses PET, PC or PP to form two steps. The two-step bottle blowing machine is widely used in carbonated beverage bottles, mineral water bottles, cosmetic bottles, edible oil bottles, pesticide bottles, large-caliber bottles, high-temperature resistant bottles and other packaging containers made of crystalline plastics such as PET and PP. For many newcomers to the plastic bottle industry, there are many things to understand and learn before purchasing, and they need to purchase according to their own needs. The more expensive the bottle blowing machine is, the better it is, but it may not be suitable for you. Since there are many types of bottle blowing machines, they are generally divided into semi-automatic bottle blowing machines, hand-inserted automatic bottle blowing machines, and fully automatic bottle blowing machines.

Problems faced by plastic bottle blowing machines
With the development of the domestic plastic bottle market, plastic bottle blowing machines have also developed rapidly. They are widely used in beverage, medicine, cosmetics and food industries, and have attracted more manufacturers to choose bottle blowing machines to replace previous bottle making tools.
Among many products, multi-layer co-extrusion hollow bottle blowing machine is a hollow bottle blowing machine with great development prospects. As the proportion of multi-layer blow-molded high-barrier hollow products in the field of hollow products increases, multi-layer blow-molded products are developing rapidly not only in the food packaging industry, but also in chemicals, cosmetics, medicine and health and other industrial packaging. Therefore, the development of bottle blowing machine is due to its excellent characteristics, and it will definitely reach its peak in the next few years.

When people use various plastic product equipment in their lives, especially the use of plastic bottles, they not only have good functional characteristics, but are also very convenient to use. Compared with glass bottles, they are not only bulky, but also small in size and light in weight, and will not break. Therefore, they are widely used by people in life or other fields. Most of these plastic bottles are made by bottle blowing machines. Bottle blowing machines are mainly a kind of equipment that uses blow molding technology to make plastic particles into hollow containers. It is not only simple to use and easy to operate, but also saves more time. The process of bottle blowing machines in making plastic bottles:

Analysis of factors affecting the bottle blowing process of bottle blowing machine
Bottle blowing machine preforms and their heating, pre-blowing (position, pressure and flow), stretch rods, high-pressure blowing (pressure, position) and molds, etc. These are the key factors affecting the bottle making process of the bottle blowing machine.
1. Bottle preforms

Methods of maintenance and repair of bottle blowing machine
After the bottle blowing machine has been used for a period of time, irregular maintenance of the equipment may cause equipment failure and reduce efficiency. Therefore, it is necessary to regularly maintain and repair the equipment to effectively extend the service life of the equipment.
1. No feeding at the feeding layer: Several situations need to be checked: Is there no material in the hopper, if yes: feed quickly. No: Make sure the control contactor of the elevator is powered. If powered, quickly check whether the motor is powered and unloaded, because in this case, the lifting belt may be stuck in the preform (bottle blank). A simple way is to do this manually. Please help lift it. If it has been confirmed that the control contactor of the elevator is not powered, check whether the electronic eye reflector for bottle blank detection is not straight.

Disadvantages of plastic bottle blowing machine and its treatment methods
Disadvantages of plastic bottle blowing machine and their solutions:
1. How to deal with the high temperature alarm in the light box water channel: remove the rubber tube connecting the water channel and use low-pressure gas and alcohol to blow and clean the water channel.
2. How to deal with jaw defects: adjust the slide height, or perhaps the position of the jaws.
3. Solution to stuck action: restart the plastic bottle blowing machine.

Introduction to the operating principle of bottle blowing machine
Blow molding machines are mainly divided into three categories: extrusion blow molding machines, injection blow molding machines and special structure blow molding machines. The processing technology is mainly divided into one-step method and two-step method. The one-step method and two-step method blow molding machine molding process are mainly used for PET and BOPP hollow containers. Both have their own characteristics and are widely used. In comparison, the two-step method is more suitable for centralized production of preforms and decentralized blowing of bottles, while the one-step method equipment is more suitable for online production of beverage companies.
