1 Out 8 Cavity Linear Blow Molding Machine
"R series all-electric version" high-speed linear PET full-automatic blow molding machine is developed and produced by our company using advanced bottle-making technology. The single-cavity capacity of the blow molding machine can reach 2000 bottles/hour/cavity (≤0.6L bottles), which can meet the needs of customers with high production capacity. It is mainly used for the blowing of PET container bottles (cold blow moulding) for packaging drinking water, beverages, edible oil, soy sauce, beer, food, etc. This machine is equipped with an automatic preformation system with high automation, stable performance and fast speed. In the entire production process, the separation of man and machine reduces pollution sources and guarantees product quality.
2. (Electric version) The performance and characteristics of the bottle blowing machine:
-- Application of servo PLC system:
Use Omron PLC servo system (motion controller, modular), use PTO (servo as a module) system for high-speed positioning, proximity sensor switch to find the target position of the track, send high-speed signals to the servo system, through the high-speed built-in servo motor The precision rotary encoder detects the position of the track online, and the information is fed back to the control system. Finally, the PLC and positioning module perform high-speed positioning.
-- Application structure of servo motor:
Mould base opening/closing power system: Double servo motors/reducers are used to drive both sides of the mold base plate to open and close the mold and the bottom mold at the same time. It moves in a clockwise circular 360-degree rotation direction, and a high-pressure pressurized air source is added to lock Mold (buffer to reduce the impact force of the mold, effectively protect the mold, and reduce the visibility of the finished bottle mold line). The servo motor power mold opening and closing structure makes full use of engineering simulation analysis to achieve the effects of high precision, accuracy and stability, fast speed, simple structure, energy saving and environmental protection of the mold opening and closing; the bottle blowing machine's blowing bottle opening and closing cycle time can reach 0.3 ~0.5 seconds/time.
Preform entering and heating stepping mechanism: the preform enters the heating box by rotating type, and the preform heating uses a servo motorreducer to drive the synchronous belt linkage transmission stepping. The 360 degree rotation of the preform heating is controlled by a frequency conversion motor. , Rotary single-row preform heating mechanism, the preform is heated by hanging mouth (bottle mouth facing upwards); it uses a servo motor to synchronize and link on a slider track for rotating high-speed stepping and positioning to simplify steps Advance action makes the stepping track fast and stable, shortens the production cycle, and greatly improves production efficiency.
The preform is heated and the preform is clamped out and the preform is divided into a variable pitch system mechanism: the preform is heated after the preform is heated, and the power of the screw variable pitch preform division uses a servo motorreducer to drive the screw and the variable pitch linkage type transmission step.
After heating, the preform is sent to the blow molding stationthe finished bottle is discharged. Step structure: the preform is heated to the blow molding station, and the finished bottle is discharged (to take out the finished bottle from the blow mold cavity) using a servo motorreducer drive Synchronous belt linkage drive stepping;
Stretching system: The bottle blowing and pulling process also uses a servo motorreducer drive (bottle mouth is upupward down), so the flexibility and accuracy of the blowing adjustment process are greatly improved (convenient Change the bottle type's lift adjustment).
-- Application of constant temperature heating box:
The thermostatic preform heating light box adopts a modular control system, which uses infrared tubes and reflectors for heating; after setting the temperature value, the device can automatically adjust the output power according to the ratio, without being affected by voltage fluctuations and The influence of environmental temperature changes; at the same time, the circulating air cooling controlled by the inverter can effectively ensure the heating temperature inside the light box, so that the surface of each preform is heated uniformly with the internal temperature. Moreover, the bottle keeps 360 degrees of rotation in the light box, so that all sides of each preform can also be heated evenly, which improves the blowing rate and the range of adaptation of thick-walled preforms; the preform is taken after the preform is heated Configure bottle temperature detection system!
-- The bottle mouth cooling adopts a circulating cooling water protection system device, and at the same time, it is supplemented by a circulating air cooling controlled by a frequency converter to ensure that the bottle mouth does not deform when the preform is heated.
-- The important parts of the whole machine (such as servo motor, reducer, electric/pneumatic parts, etc.) are imported famous brand products from Europe, America and Japan to ensure the reliability, stability and life of the equipment;
-- Man-machine interface control, simple operation, overall computer control, including temperature adjustment and embryo delivery;
-- Independent and movable operation platform box makes it more convenient and flexible to arrange operation.
-- When the automatic embryo processing system is in processing the embryo, each embryo channel has a detection photoelectric switch detection, which controls the action of the epidermal motor and the embryo dividing cylinder to ensure the uniform distribution of the embryo tube in each embryo channel, and has the function of alarm for lack of material;
-- The process of preforming, preforming, taking out and discharging bottles is all automated to avoid secondary pollution; the loading hopper is equipped with a dust-proof cover (stainless steel) to meet the dust-proof and hygienic standards.
-- The mold installation method is "drawer push type" up and down positioning installation, the staff only need to operate and replace on the ground, which is safer, more convenient, faster and more efficient; the mold base of the blowing machine is equipped with a bottle mold installation swing arm (It can be equipped with a hoist crane), which can easily and quickly complete mold replacement within an hour;
-- The programmable logic controller (PLC) and the machine are connected through a specific communication cable, and the user can manage all the operations of the machine through the PLC. Once the machine has a fault, it will provide the operator with a warning signal and a fault diagnosis report. The operator can quickly find the cause of the fault and eliminate it as soon as possible through the fault display.
-- The reciprocating parts of the bottle blowing machine are equipped with protective devices and warning signs.
-- The high-pressure blowing valve of the bottle blowing machine can be equipped with a device that converts to low-pressure gas, which can ensure that it can be converted normally without low-pressure gas; during the blowing production process, the gas source discharged after the blowing can be recovered The low pressure cylinder is reused.
