1. The power supply, vacuum system, air pressure system and cooling system should be checked before each start-up of the bubble film machine. After the start-up of the equipment, the rotation direction of the rotating parts should be checked correctly. At ordinary times, the lubrication situation of the lubricating parts should be checked. Electrical instruments should be maintained and maintained normally in accordance with the regulations.

2. Bubble film machine should assign special person to operate the equipment. It is not allowed to idle the screw of extruder without material, so as to avoid scratch of screw and barrel. After shutdown, if there is material in the barrel, before starting again, the temperature of each temperature zone must be raised to the specified requirements according to the process requirements, and the temperature should be kept for more than 30 minutes before starting up. It is strictly forbidden to start before the temperature does not meet the requirements, so as to avoid damaging the machine parts.
