Rotary one-drag-three plastic packaging machine is a relatively large equipment, the correct use of rotary one-drag-three plastic packaging machine can last for a long time, before use, we must do a good job of adjustment, or it will bring a lot of trouble to our future work, so what adjustments do we need to make to the shrinkage machine just bought? The power of the shrinking machine is generally about 18-40KW, and the setting temperature is also relatively high, generally between 170°-230°. According to the thickness of the material, the speed of conveying the product, the size of the air volume and the temperature setting are also different. If the product is not resistant to high temperature, the low temperature can be used and the thin shrinkage film can be used. If the shrinking film is thick, the temperature needs to be increased, and the power of the shrinking machine also needs to choose a larger one. When the speed of conveying products increases, the temperature increases accordingly, on the contrary, when the air volume increases, the temperature decreases accordingly, and vice versa.The power of the rotary one-drag-three plastic packaging machine is generally 5-20KW, and the temperature is generally set at 140-°160 °. The adjustment is basically the same as the rotary one-drag-three plastic packaging machine.
The air volume generally uses frequency conversion speed regulation to control the speed of the motor. However, many shrinkage machines do not have this function, and the powerful ones also have the adjustment of the wind direction, which effectively blows the hot air to the position where the product needs to shrink, and the air volume also has a great influence on the shrinking effect, and the shrinking film is heated instantly when the air volume is too large. expansion can easily lead to post-shrinkage bursts that affect the shrinkage effect. The air volume is too small and the intima does not contract for a short time. Fish scale lines will appear on the surface. The size of the wind volume is also related to the size and angle of the wind wheel. The higher the temperature, the smaller the air volume, and vice versa, the faster the speed, the larger the air volume, and vice versa.
