The principle of automatic bottle blowing machine
When the equipment starts to blow the bottle, the high-pressure gas in the bottle enters the recovery gas storage pipe 6 through the exhaust pipe of the three-way valve 10 and the one-way valve 12. After the equipment runs for one circle and recovers enough gas, the manual solenoid valve 1 is used to close the original puller.
When the equipment starts to blow the bottle, the high-pressure gas in the bottle enters the recovery gas storage pipe 6 through the exhaust pipe of the three-way valve 10 and the one-way valve 12. After the equipment runs for one circle and recovers enough gas, the manual solenoid valve 1 is used to close the original puller. Extend the low-pressure intake and pre-blowing intake lines. At this time, the stretching cylinder and the pre-blowing air are supplied by the recovery air storage pipe. Due to the different bottle volumes (0.6L, 1.25L, 2.0L, etc.), we can properly Open the exhaust valve 9 and discharge the excess air from the muffler to maintain the balance between the recovered air and the consumed air. If there is still residual air in the recovered air storage pipe, it will be discharged through the 15bar valve 4, so the valve has enough flow, which can Let the excess gas be discharged, and open the manual solenoid valve when the bottle blowing is stopped to supply air from the original low pressure and pre-blowing lines.
Although this system only provides recycled gas to the two parts of stretching and pre-blowing, it seems to be a bit of a fly in the ointment, but its investment is small (take SBO10/14 as an example, only about 20,000, depending on the price of accessories), and the return is large (yearly Cost savings of 160,000 to 200,000), strong independence (the original gas supply system can be used in case of failure or other reasons), high flexibility (simple and convenient installation), in line with the basic principles of our technical transformation project, making the product more market competitiveness.
When the machine is idling and the bottle is not blown, the low-pressure gas passes through the solenoid valve of the original pipeline to the gas storage pipe of the stretching cylinder, and the recovery gas storage pipe and the gas storage pipe of the stretching cylinder are isolated by a one-way valve. At the same time, the entire stretching air system and pre-blowing system are kept as they were before modification.
The working principle of the whole system of the automatic plastic blow molding machine is relatively simple. Since only the stretching cylinder and the pre-blowing part are required, the installation structure is also convenient. Bottles should grasp the relationship between supply and demand.
The sales volume of blow molding machines in recent years has been better than before. At present, my country's blow molding machine manufacturers have developed their own core systems for blow molding machines, while the high-end market is just the opposite. one part.
The factors that affect the quality of the bottle blowing machine of the mineral water blow molding machine include: preform and its heating, pre-blowing (position, excitation and flow), stretching rod, pressure blowing (pressure and excitation position), and molds, etc.
