Automatic Bottle Blowing Machine

1.Introduction of blow molding machine

The bottle blowing machine is a device for making plastic particles into hollow containers through a blow molding process. It can blow the finished preform into a bottle through a certain process.

Its characteristic is to separate the drying tunnel and the bottle blowing, which speeds up the bottle blowing speed and increases the output value.

It is divided into two major control systems (customers can choose freely)：

One is controlled by a time relay, and the other is controlled by a PLC touch screen computer.

2.Common features of fully automatic blow molding machine

There are many types of fully automatic blow molding machines, and we must pay attention to selecting the appropriate model for production when we use it.

Features of automatic bottle blowing machine:

（1）Each heating zone is equipped with independent segmented temperature control; the position and distance of the lamp tube and reflector in the heating zone can be adjusted according to the different shape and size of the preform to achieve the ideal heating effect.

（2）The constant pressure temperature adjustment method is used to control the heating of the preform by the infrared lamp to ensure the proper, accurate and stable heating of the preform without being affected by changes in the input voltage.

（3）According to different product requirements, this automatic bottle blowing machine can be equipped with a dual-chamber double-stretching cylinder, a three-chamber three-stretching cylinder, a four-chamber four-stretching cylinder, or a six-chamber six-stretching cylinder design. Adjust the use of single-cavity single-stretching cylinder to meet the different needs of machine adjustment or mold trial.

（4）The control system is equipped with an automatic fault reporting function; when an operation error or malfunction occurs, the computer will display and give an alarm.

（5）Mold replacement is convenient and quick, and there is no need to adjust the thickness of the mold within the range of the corresponding

（6）The production process is fully automated, and multiple machines can be combined to a fully automatic production line at the same time. The entire production process does not require human hands to touch the preforms or finished bottles. machine.

3.How to use the automatic bottle blowing machine

When the room temperature blow molding machine is used in the installation position, the bracket and spray parts are placed in the protective ground room, about 5 meters to 8 meters away from the door; the air compressor cart is placed outdoors, and the spray parts are connected with cables and air hoses. . The operator can operate the electrical cabinet of the air compressor trolley outdoors. The spray parts and brackets can be carried by a single person, and can be quickly disassembled, inserted before spraying, and carried out after spraying. The whole set of machines can be operated by one to two people. At present, the type and dosage of the normal temperature bottle blowing machine are the same as those of the manual bottle blowing machine.

The large motor drives the air compressor to generate compressed air (pressure of 150 kPa to 201 kPa), which enters the vortex chamber of the nozzle through the air hose. A high-speed rotating airflow is generated and a partial vacuum is formed. The medicine tank liquid is sucked into the nozzle through the infusion tube, and the air and liquid medicine are mixed at high speed and atomized into a blown bottle with an average diameter of about 20 microns, which is sprayed from the nozzle. At the same time, the small motor drives the axial flow fan to generate low pressure and large air flow, blowing the nozzle to the far place. It can propagate more than 30 meters along the axis, and the width can reach more than 6 meters. After 30 minutes to 60 minutes of spraying in the limited confined space of the protected area, the blowing bottles can be evenly distributed and float around the room. And suspended in the space for 2 hours to 3 hours, so that the bottle blowing can fully contact with the active parts of crop diseases and insect pests, and produce a better control effect. This machine is applicable to emulsions, wettable powders, liquids, oils, etc. The spout can be adjusted in the height range of 0.9 meters to 1.3 meters according to the height of the crop varieties.

4.Precautions for purchase of bottle blowing machine

For blow molding machines, many people who are new to the plastic bottle industry need to understand and learn a lot before purchasing, and they also need to buy according to their own needs.

（1）For some large-scale beverage, mineral water or cosmetics manufacturers, because they use a large amount of packaging, they are often integrated with the product filling. This type of bottle blowing machine should choose a fully automatic, high-speed, stable and reliable bottle blowing machine. Machinery, only such a blow molding machine will not affect other links in the later production process and affect the overall production efficiency.

（2）For some small and medium-sized manufacturers, you can consider a semi-automatic, two-step blow molding machine. On the one hand, it can reduce the cost of purchasing a blow molding machine, and on the other hand, the production capacity of this type of blow molding machine is relatively low. More in line with the needs of manufacturers.

（3）For some individual or family workshops, you can consider using second-hand blow molding machines at the beginning. This type of blow molding machine is relatively low in price. As long as you understand the parameters of various aspects, then buy, there are still many cost-effective machines worth choosing.
