The dalian film industry will welcome major renewal reform

The energy saving of the film blowing machine can be divided into two parts: the power part and the heating part. Energy-saving power parts: mostly adopts frequency converter, motor energy saving way is by saving more energy, the real power of the motor is 50 hz, for example, and in production, in fact, you only need 30 hz enough production, that extra energy is wasted, the inverter is to change the motor power output to achieve the effect of energy saving. Heating part energy saving: most of the energy saving is energy saving with electromagnetic heater, the energy saving rate is about 30% to 70% of the old resistance circle.

The film is only the first step, and the subsequent sea demon is made into a thin film bag as the terminal product. This is the choice machine which should be selected by the end film bag specification. The simple blown film only sells the film as the end product, so the range of choice device adaptability is wider, from the narrowest door to the widest door width to satisfy the need as far as possible. And the type of finished film (such as high pressure polyethylene film, low pressure polyethylene film, etc.) should be produced by the equipment.

The development of science and technology let the industrial production from the human production to mechanized production, inevitably because the operating machine safety accidents occur and their reasons, so the following will introduce blown film machine, preparation before starting work, reduce the occurrence of safety accidents: check whether the blown film machine installation work is installed according to the requirement, and check all bolts in good condition. The material requirements should be dry, otherwise pre-drying should be done. Check the power and electrical parts, and the parts should be safely grounded. It is not filled with plastic. It is filled with plastic and temperature is not required.

The feed and the lower pressure device of small blowing machine are out of sync. The feeding material is too fast, too slow or too tight, and the lower pressure device is too loose. The longitudinal sealing knife ironing cloth is too tight. Increased pressure for feeding. The bag machine tracking power is not obvious. The quality of tracking parts is not good, or use too long, the actual effect is not obvious, can not play the proper function well.

The next thing is to determine how much force the pressure spring in the bag machine needs (or can output) when compressed a millimeter. This requires knowing the spring constant of every pressure spring on the machine. The actual output force value of the pressure spring is the product of the precompressed length of the pressure spring with its spring constant, which is F = KL.
