instructions
The "all-electric version" high-speed linear full-automatic bottle blowing machine is developed and produced by our company using advanced bottle making technology. The single mold cavity capacity of the bottle blowing machine has been increased from the original 1000 bottles/hour to the maximum 1800 bottles/hour/cavity (≤ 600ml bottles), which can meet the needs of customers with high capacity. It is mainly used for the blowing of PET containers and bottles (cold blow mold), such as drinking water, beverages, food, cosmetics, medicine, etc. This machine is equipped with automatic embryo loading system, with high degree of automation, stable performance, and fast speed. During the whole production process, man-machine separation, reduce pollution sources, and ensure product quality.
Performance and characteristics of (electric version) bottle blowing machine:
1. Application of servo PLC system:
The Omron PLC servo system is used, and the PTO (servo set as module) system is used for high-speed positioning. The proximity sensor switch looks for the target position of the track and sends high-speed signals to the servo system. The position of the track is detected online through the high-precision rotary encoder built in the servo motor, and the information is fed back to the control system. Finally, the PLC and positioning module perform high-speed positioning.
2. Application structure of servo motor:
Mold opening and closing power system of mold base: a servo motor reducer is used to drive the mold opening and closing of both sides of the mold base plates and the bottom mold through the synchronous belt drive. The synchronous mechanism adopts the clockwise 360 degree rotation direction (when the servo motor drives the synchronous belt to rotate for half a turn, a mold opening and closing cycle can be completed), The high-pressure pressurized air source is used to supplement the mold locking (cushion to reduce the impact force of the mold, effectively protect the mold, and reduce the visibility of the finished bottle mold closing line). The servo motor power opening and closing die structure makes full use of engineering simulation analysis to achieve the effect of high precision, accuracy and stability, fast speed, simple structure, energy conservation and environmental protection; The opening and closing cycle time of bottle blowing machine can reach 0.3~0.5 seconds/time.
Stepping system: bottle embryo heating, bottle embryo delivery to blow molding station The action of the finished product bottle outlet stepping system uses a servo motor to synchronously move on a slider track for rotary high-speed stepping positioning [when the servo motor drives the tooth plate to rotate for half a circle, a step cycle can be completed (that is, 6 bottles are heated at the same time, 6 bottles are blown into the molding station, and 6 bottles are discharged from the finished product bottle] , simplify the step action as a whole, make the step track fast and stable, shorten the production cycle, and greatly improve the production efficiency).
Stretching system: the servo motor is also used in the bottle blowing and lifting process, which greatly improves the flexibility and accuracy of the bottle blowing and adjustment process (convenient for changing the flexible adjustment of various bottle types).
3. Mold design positioning installation, mold replacement and installation is simple and fast, and mold replacement can be easily and quickly completed within one hour;
4. The arrangement structure of the heating box saves the heating space and energy consumption, and makes full use of the internal space;
5. Application of thermostatic heating box:
The thermostatic light box adopts a self-feedback closed-loop control system. After setting the temperature value, the equipment can automatically adjust the output power in a constant and proportional manner, without being affected by voltage fluctuations and environmental temperature changes. At the same time, the frequency converter is used to control the circulating air, which can more effectively ensure the constant temperature inside the lamp box, so that each bottle embryo is uniformly heated. In addition, the bottle keeps rotation in the light box, so that all sides of each embryo can also be heated evenly, thus improving the finished product rate of bottle blowing and the adaptability of embryo wall thickness (up to 4.5mm); It is more suitable for the environment with large temperature difference (- 28~45 ℃).
6. The circulating cooling water protects the bottle mouth system device to ensure that the heated bottle mouth of the bottle embryo does not deform;
7. The important parts of the whole machine (such as electrical, pneumatic parts, servo motors, reducers, etc.) are imported from Europe, America and Japan to ensure the reliability, stability and service life of the equipment;
8. Man-machine interface control, simple operation, overall computer control, including temperature adjustment and embryo feeding quantity;
9. Independent operation box, more convenient and flexible arrangement of operation positions;
10. When the automatic embryo management system is in the process of embryo management, each embryo channel has detection photoelectric light detection, which controls the action of the upper embryo motor and the embryo separation cylinder, ensures the uniform distribution of the embryo tubes in each embryo channel, and has the function of material shortage alarm;
11. The process of automatic embryo cutting, embryo loading, bottle taking and bottle arrangement is automatically completed by the manipulator to avoid secondary pollution in the middle;
12. The programmable logic controller (PLC) is connected with the machine through a specific communication cable. The user can manage all the operations of the machine through PLC. Once the machine has a fault, it will provide the operator with a warning signal and a fault diagnosis report. Through the fault display, the operator can quickly find the cause of the fault and eliminate it as soon as possible
