The operation process of the film blowing machine ‌ mainly includes the following steps:

‌ Prepare before starting ‌ :
‌ Safety dress ‌ : Operators should wear professional protective clothing and work cap to ensure that the dress is neat and in line with safety regulations. ‌
‌ Environmental cleanup ‌ : thoroughly clean the surrounding environment of the equipment to ensure that no debris is stacked, so as not to affect the normal operation of the equipment and personnel safety. At the same time, clean the workbench and equipment inside and outside, wipe key components with clean cotton yarn. ‌
‌ Equipment inspection ‌ : carefully check whether the control switches, buttons and electrical circuits of the equipment are in good condition to ensure that all components are in the best condition. Special attention is paid to the safety protection device to ensure its sensitivity and reliability.
‌ raw material preparation ‌ : Check whether the hopper is clean and free of foreign matter to ensure the quality of raw materials. According to the process requirements, materials and ingredients to ensure that the ratio of raw materials is accurate, no excessive moisture phenomenon.

‌ Boot operation ‌ :
‌ Start the cooling system ‌ : First start the cooling water system to provide the necessary cooling for the feeding device to ensure the stable operation of the equipment.
‌ heating up ‌ : start the heating device, set and wait for the temperature to meet the process requirements. During this process, it is necessary to constantly check the heating section indicator to ensure that the temperature control is accurate.
‌ charging production ‌ : When the temperature is stable, the charging production begins. Adjust the screw speed according to the molten state of plastics to ensure uniform extrusion of materials. At the same time, through the air ring, traction roller and other devices, the extruded tube bubble is gradually flattened, sliced, and finally sent to the winding device. ‌
‌ process monitoring ‌ : During the production process, it is necessary to pay close attention to the uniformity, thickness and appearance quality of the film, and adjust and optimize it in time. At the same time, pay attention to the running status of the device, and stop the device immediately if any exception is found.
‌
Shutdown end ‌ :
‌ stop production ‌ : After the completion of the production task, first stop the corona system, and then gradually reduce the extruder and traction speed to stop.
‌ shut down the equipment ‌ : shut down the air ring fan and heating power supply, and shut down the cooling water system only when the temperature of the waiting cylinder drops to the safe range. Finally, the monitor will conduct a comprehensive check and confirm that the main power supply is cut off and officially shut down.
‌ site cleaning ‌ : clean up the debris, oil stains and dust around the equipment and workbench, and keep the workplace clean and tidy. At the same time, do equipment maintenance work to prepare for the next production.
‌
Precautions ‌ :
Before starting, it is necessary to check whether the safety protection devices of all parts of the equipment are intact, sensitive and reliable, and the safety protection devices on the equipment are not allowed to move or modify. ‌
When the machine is running, do not touch the rotating part with your hand to avoid accidents.
If you drive after a long stop, the heating temperature at each point needs to be constant for 10-30 minutes after reaching the target range, if you drive within half an hour of parking, you do not need constant temperature.
