According to special demand, adopt cross double crank pressed clamping, with strong clamping force. Mould open stroke can be adjustable according to the bottle size to save the time. The heated preform enters the mold coupler for blowing. The hot preform enters the mold coupler, and the preform is sealed, with pre-blowing gas. The stretching rod at the bottom stretches the preform upward, pre-blows the gas to a certain extent, blows at low pressure, and at the same time enters the blowing at high pressure, and the bottle is instantly formed in a short time to complete the blowing. Before pre-blowing the gas, a refrigeration dryer is generally installed. The gas passes through the filter, which filters the moisture in the air and the oil in the equipment, and the formed bottle has no oil smell.

The Process Flow of the Bottle Blow Molding Machine
The blow moulding machine process of the bottle blow molding machine is a two-way stretching process. In this process, the PET chain is extended, oriented and arranged in two directions, which increases the mechanical properties of the bottle wall. It improves the tensile, tensile, and impact strength. It has good airtightness. Although stretching helps to increase strength, it should not be overstretched. It is necessary to control the stretch-inflation ratio: Do not exceed 3.5-4.2 in the radial direction and 2.8-3.1 in the axial direction. The wall thickness of the preform should not exceed 4.5mm.
Blowing is carried out between the glass transition temperature and the crystallization temperature, generally controlled between 90 and 120 degrees. The PET exhibits a highly elastic state in this interval and becomes a transparent bottle after rapid blow moulding and cooling, and setting. This temperature is determined by the length of the cooling time during the injection moulding process (such as the Aoki bottle blow molding machine), so the relationship between the injection and blowing stations must connect. The blowing process includes stretching-blowing once-blowing twice. The three actions are concise, but they must be well-coordinated, especially the first two steps to determine the overall distribution of the material and the blowing quality.
Therefore, it is necessary to adjust: stretching start timing, stretching speed, pre-blowing start and end timing, pre-blowing pressure, pre-blowing flow, etc.; if possible, it is better to control the overall temperature distribution of the preform, bottle The temperature gradient of the inner and outer walls of the blank. In the process of rapid blow moulding and cooling, induced stress is generated in the bottle wall. For gas-filled beverage bottles, it can resist internal pressure, which is beneficial. Still, hot-filled bottles must ensure that it is fully released above the glass transition temperature.
In food, cosmetics, medicine and other industries, the demand for plastic blowing bottle machine is growing year by year. The volume of hollow vessels can reach thousands of liters, and some production has been computerized. Suitable for blow molding plastic polyethylene, polyvinyl chloride, polypropylene, polyester, etc., the resulting empty container is widely used as industrial packaging containers.
At present, most bottle blow molding machines are still two-step blowing machines, that is, plastic materials must be made into the bottle embryo, and then blowing. Nowadays, environmental friendly plastic made of PET material is commonly used. Blow molding machine: after the liquid plastic is sprayed out, the machine blows out the wind, the plastic body is blown to a certain shape of the cavity, so as to make products, this machine is called blow molding machine. Is also a bottle blow molding machine, that is, hydraulic bottle blow molding machine. The rapid development of bottle blow molding machine has been adopted by many industries, mainly due to its distinctive characteristics. First of all, the bottle blow molding machine adopts oil-free air bag clamping technology, which has large clamping force, less force for elbow joint operation and long service life.
What Is the Development Status of Bottle Blow Molding Machine
A bottle blow molding machine is a kind of hollow blow molding equipment. So far, the bottle blow molding machine has made great progress in the blow molding process and molding machinery. The blow molding technology is widely used in polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate Blowing plastic bottles such as glycol ester (PET) and polycarbonate (PC) . Polyethylene Terephthalate (PET) was first developed.
With higher requirements for the automation and intelligence of the bottle blow molding machine, the traditional sequential control system can no longer meet the needs of the multi-axis linkage of the bottle blow molding machine. An increasing number of bottle blow molding machine systems use an all-electric servo control system. The servo motion controller has high-speed communication and various motion control methods, which can realize electronic gear, electronic cam, interpolation and multi-axis linkage control, which can further improve the efficiency and quality of the bottle blow molding machine.
A PET bottle is a hollow plastic product that is formed by hollow blow molding. Hollow blow molding is a process in which the hot-melt plastic in the closed mold is inflated with compressed air and then shaped into a hollow plastic product after cooling. The main methods of hollow blow molding can be divided into two categories: extrusion blow molding and injection blow molding. In addition, on the basis of extrusion blow molding and injection blow molding, extrusion-stretch-blow molding method and injection-stretch-blow molding method have been developed, which can be specially classified as stretch blow molding Law. Equipment using extrusion blow molding, injection blow molding and stretch blow molding methods are called extrusion bottle blow molding machine, injection bottle blow molding machine, extrusion stretch bottle blow molding machine and injection stretch bottle blow molding machine, respectively.
Before turning on the plastic bottle blowing machine in each shift, it is necessary to add lubricating oil to each movable part once. (Manipulator, manipulator guide rail, mold opening and closing guide rail). The swing arm can be added once every (3-4) days. The large chain and small chain of the heating machine can be used once a month. Frequently check whether the reducer of the main engine and the reducer of the heating machine are short of oil. The main engine bearing can be added once a month (2-3). Before consumption, check whether the moving parts are strong and whether the screws are loose and scattered, especially whether the center with strong impact force and the belt drive part are abnormal. Check whether the high-pressure gas source, low-pressure gas source, power source, and water source are normal.
Check whether the emergency stop switches, safety door switches, maintenance and installation detection switches are normal. Check whether the heating head enters the embryo, and the part of the embryo fails to work normally. If the insert is not in place, the mounting nut can be adjusted. Check whether the lamp tube is damaged or broken. Change in time. Check whether the pneumatic components can leak air and whether they can move flexibly. Check whether the triplet is leaking abnormally, whether it is blocked, and whether the water cup is too full.
When the solenoid valve of the plastic bottle blowing machine encounters an abnormality, it must be cleaned in time. The mold of the plastic bottle blowing machine must be cleaned and polished regularly. When opening the upper and lower pressure air source switches, the action must be slow to prevent the air source flow rate from blowing dirt into the solenoid valve. At the same time, open the exhaust valve for 30 seconds to ensure that the air is clean. When starting the plastic bottle blowing machine, you must make sure that the part of the machine is in good condition, there is no one inside the machine, and there is no foreign matter. Especially the crank position, so as not to hurt people. At the same time, close the safe door. When starting the machine, it is necessary to start the motor first, and delay the start of the heating machine for 30 seconds to prevent the voltage from shaking. Make sure that the cooling water is turned on before starting the heating. After the heating is started (2-3) minutes, wait until the temperature of the oven rises evenly, and then press the embryo button. At the same time, the blowing must be turned on, otherwise the blowing will not be possible.
When the plastic bottle blow molding machine is in operation, it is necessary to pay close attention to whether the machine has abnormal noise, and to find out early, stop it in time and deal with it early. In case of emergency, you can press the emergency stop button to make an emergency brake. Then analyze the cause of the composition based on the on-site situation and find the problem to be solved quickly. After normal operation, do not extend any part of the body into the machine to avoid injury by the manipulator. If the machine has abnormal noise, it can be decelerated and stopped for inspection. After normal consumption, the operator must always check the quality of the bottle, so as not to affect the quality of the bottle blowing due to voltage fluctuation or other reasons. When repairing, press the touch screen fault repair button to ensure safe repair. If you need to manually observe the movement of each cavity individually, please pay attention to the position of the manipulator. At the same time, be sure to clarify the role of the separate button before you act. Make sure that the misoperation causes unnecessary trouble.
