What is the preparation of the auxiliary machine of the plastic blow molding machine before driving?

September 11, 2021

What preparations should be done before driving the auxiliary machine for plastic production of plastic bottle blowing machine?
① Check whether the fastening nuts and safety covers of various parts of the auxiliary machine of the plastic Bottle Blowing Machine are loose, move the pulley of the transmission system by hand, and check whether the transmission parts are running normally.
②Check whether the plastic blower electrical control box has grounding protection. Test whether the emergency stop button can work in time and accurately.
③ Check whether the test power supply, water supply and compressed air, heating and cooling systems are correctly connected and there is no leakage.
④According to the product film thickness requirements, inflation ratio and draft ratio, determine the die gap, and use a feeler gauge to check the uniformity of the gap on the die circumference. Then fix the adjustment screw.
⑤The heating temperature of the molding die and the barrel are heated at the same time. After reaching the process temperature, the temperature is kept constant for 30 minutes. At the same time, the mercury thermometer is used to check and correct the temperature display error on the temperature control instrument.
⑥ Check and verify the distance between the air ring and the die (generally 30 ^ -80mm), check the test tuyere angle and air volume. Check and adjust the angle of the herringbone board, the contact between the two rollers of the traction roller and the clamping force.
Test the working operation of the traction roller and the reeling package.
Eliminate the found faults, clear all auxiliary tools and equipment that are not related to production, and prepare for production.
