What are the requirements for the screw to operate the bubble film bag making machine?

Bubble film bag making machine can produce various special air cushion films such as anti-static films by adding different additives to the plastic raw materials. Anti static air cushion film is used to package electronic components and components, such as boards, cards, etc. It can prevent static electricity and play a role of cushioning and anti vibration. Aluminum foil bubble film is generally used for heat insulation of car sun shield and roof. Assign special personnel to stop the bubble film machine, and do not allow the extruder screw to idle when there is no material, so as to avoid scratching the screw and barrel. After shutdown, if there is material stored in the barrel, before restart, the temperature of each temperature zone must be raised to the specified requirements according to the process requirements, and the machine can only be started after holding for more than 30 minutes. It is strictly prohibited to start the machine before the temperature reaches the requirements, so as not to damage the machine parts. The bubble film machine shall be overhauled regularly, the die head shall be thoroughly cleaned every three months, the lubricating grease of various bearings shall be replaced, the lubricating oil of the reducer shall be replaced every six months, and the overall equipment shall be overhauled every two years. If the screw is taken out of the barrel for some reason, it shall be properly treated to prevent deformation. If it is not installed back into the barrel for a long time, the screw must be vertically hung to prevent bruise, bending and permanent deformation. The barrel and screw surfaces shall be coated with antirust oil for protection.
