The PE blown film machine is mainly composed of feeding system, extrusion system, forming system, cooling system, and winding system. The feeding system mainly includes a feeding port, a barrel, and a screw, which are used to feed polyethylene particles into the extruder. The extrusion system consists of an extruder, extrusion head, and die head, responsible for heating and melting polyethylene particles and extruding them into a film. The forming system consists of forming rollers and a folding device, used to shape and fold extruded polyethylene film. The cooling system mainly includes cooling rollers and air coolers, which are used to cool the formed polyethylene film. The winding system mainly includes winding rollers and winding mechanisms, which are used to wind the cooled and formed polyethylene film.
In industry, the film produced by PE blown film machines can be used to make industrial packaging materials, such as dust covers and moisture-proof packaging for products. At the same time, some special industrial films, such as insulation films in the electronics industry, are also produced through PE blown film machines and processed through special processes. These films need to have good insulation and physical properties to meet the requirements of industrial production.
What are the common faults of PE blown film machine? How to exclude it?
Conveyor belt malfunction: When the PE blown film machine conveyor belt malfunctions, it is usually caused by loose, broken or damaged bearings. The solution is to check the status of the conveyor belt in a timely manner. If looseness or breakage is found, the conveyor belt should be adjusted or replaced in a timely manner; If the bearing is damaged, a new bearing needs to be replaced.
Extruder malfunction: When the extruder of the PE blown film machine malfunctions, it may be caused by high extruder temperature, blocked material cylinder, or damaged screw. The solution is to investigate one by one according to the specific situation: if the temperature is too high, the temperature should be adjusted; If the material cylinder is blocked, it should be cleaned; If the screw is damaged, a new screw needs to be replaced.
Cooling roller malfunction: When the cooling roller of the PE blown film machine malfunctions, it may be caused by unstable cooling roller temperature, roller surface damage, or roller bearing damage. The solution is to check and handle according to the specific situation: if the temperature is unstable, the cooling system should be adjusted; If the roller surface is damaged, a new roller surface needs to be replaced; If the roller bearing is damaged, a new bearing needs to be replaced.
Stretching roller failure: When the stretching roller of the PE blown film machine malfunctions, it may be caused by improper spacing between the stretching rollers, damage to the roller surface, or damage to the roller bearings. The solution is to adjust and handle according to the specific situation: if the spacing is not appropriate, the roller spacing should be adjusted; If the roller surface is damaged, a new roller surface needs to be replaced; If the roller bearing is damaged, a new bearing needs to be replaced.
Adjusting the film thickness of the PE blown film machine requires comprehensive consideration of factors such as extrusion volume, cooling speed, specification plate spacing, and pressure. Through continuous debugging and observation, better film thickness control can be achieved. Only by continuously accumulating experience during the operation process and flexibly adjusting according to the actual situation, can high-quality film products that meet the requirements be produced.
PE blown film machine needs to pay attention to some issues in the production process, such as temperature control, pressure control, speed control and other parameter settings of the extruder, to ensure that the thickness of the extruded film is uniform and consistent; Temperature control of the cooling roller to avoid film deformation caused by insufficient cooling; The improvement of safety protection measures ensures the safety of operators; Regular maintenance and upkeep of equipment to extend its service life.
