shrink machine use and adjustment

shrink machine( polyolefin shrink film-pof shrink film)three agencies use and adjustment:

( a ), polyolefin shrink film-pof shrink film, shrink machine temperature adjustment:

(Polyolefin shrink film-pof shrink film) shrink machine power usually large at around 20-40KW, set the temperature is relatively high, generally in the 180 degrees - 220 degrees, according to the thickness of the material, product conveying speed, wind transported quantity, temperature settings are also different, the product is high temperature resistant can use low temperature, the polyolefin shrink film-pof shrink film thin. Polyolefin shrink film-pof shrink film thick words temperature needed to be heightened, shrink machine power also need to choose the big point. Product conveying speed temperature corresponding to high, and reduce, increase transport air temperature decreased, whereas elevated. Polyolefin shrink film-pof shrink film, PVC shrink machine power 5-20KW in general, usually set at 140 degrees of temperature of about 160 DEG PE shrink machine adjustment and basically the same

( two), conveyor belt speed adjustment:

Most manufacturers use converter, transmission electronic speed regulator to control the speed. Polyolefin shrink film-pof shrink film long words speed must be slow,( polyolefin shrink film-pof shrink film) shrink machine conveyor to long, generally to in 20m / min-60m / min if the product on the contractile effect requires very high, recommend the use of longer shrink machine, using low temperature and slow delivery to meet the contraction effect. Choose more power model. Temperature setting high transportation speed needed to speed up, or slow down. Transport air transport and accelerate the speed of small.

( three), air flow adjustment:

Volume size generally uses frequency control, control of motor speed. But a lot of polyolefin shrink film-pof shrink film shrink machine without this function, strong function and the adjustment, effectively the wind to the polyolefin shrink film-pof shrink film need contraction of the position, the size of air on the contractile effect is affected, volume polyolefin shrink film-pof shrink film too much instant heating, expansion is very easy to cause contraction after the explosion export effects of contraction effect. Air volume is too small for a short period of time polyolefin shrink film-pof shrink film no shrinkage surface will appear fish scale. Quantity and wind wheel size, angle relation. The higher the temperature and air quantity regulating small, big, fast air quantity regulating, and small.

So (polyolefin shrink film-pof shrink film) shrink machine heating mechanism, a blowing mechanism, conveying mechanism adjustment are reciprocal, changing a parameter will affect the other parameter settings, specific details must according to the characteristics of the product, polyolefin shrink film-pof shrink film type and thickness, the capacity requirements to fine tuning the parameters, in order to achieve polyolefin shrink film-pof shrink film contraction of smooth surface appearance, polyolefin shrink film-pof shrink film contraction after non-explosive mouth, fold, and other phenomena
