Bottle blowing machines in production will produce what kind of uncertainty

Bottle blowing machine in the production of temperature control is not accurate or temperature deviation, temperature measurement point ( Thermocouple) Installation position is not reasonable, make temperature periodic deviation, with the increase of temperature deviation range, the influence of weight deviation is also increased. At higher temperatures, extrusion cylinder drawing more, in the same operation cycle, increase in the number of shuikou material bottle, product weight. At low temperature, the product weight. When there was a poor contact thermocouple, have similar failures, bad, if the thermocouple is extrusion amount decreases, and below the temperature of the plastic melting point again, motor current increases. Below the melting point of plastic extrusion. Installation of thermocouple is reasonable and the area size of thermocouple temperature measuring point, will directly affect the extrusion stability. 2 do not match the running time, two die set ( Difference is too big) , if the feed tube downward flow of constant speed, or so on both sides of the die set running time difference is large, appear on both sides of the weight is not stable. Die set run faster weight is heavier, die set run slower due to the relationship between tensile lighter weight. The solution is to adjust the die set close to the travelling time on both sides. 3, extrusion is stable, encounter unstable due to the speed of the motor running, and by the light of belt tightness is not suitable for extrusion amount caused by unstable. 4, the reason of plastic raw materials, due to the different plastic raw materials or mix proportion change caused by discharging, add water material floolwing ( The percentage) Often change impact extrusion
