The preparation work of the Zhongli film blowing machine must be done before starting

Preparatory work and precautions before starting the film blowing machine of Zhongli: Check whether the installation of the unit is installed as required, check that the bolts are well tightened; check the power supply and electrical parts, and all parts should be safely grounded; check and add Good gearbox, lubricating oil in the air compressor, check the lubrication of each mechanical transmission part; the material should be dry, otherwise it should be pre-dried; check that there should be no foreign matter in the blank, and there should be no iron filings or other inconsistencies in the raw material The required materials are mixed in; if the barrel is not filled with plastic or filled with plastic and the temperature does not meet the requirements, it is forbidden to start. Check that the heating system and temperature measurement system of this unit are intact; unrelated personnel should leave during the start-up process to prevent local overheating of the material and burn out; to prevent belts and mixing drums from being pierced; to prevent hair and clothing from being rolled in.

The normal start-up steps of the plastic film blowing machine: heat the extruder body, die head, and control the temperature of each point within the index. If you drive after a long stop, the heating temperature of each point needs to be kept at a constant temperature for 10-30 minutes after reaching the target range. If you drive within half an hour of parking, no constant temperature is required. Start the air compressor and stop when the storage cylinder pressure is 6-8kg/cm. According to the film folding diameter, thickness requirements and extruder production capacity for processing, estimate the pulling speed and stable bubble diameter. After the temperature of each point meets the requirements, put on labor protection supplies, and start the tractor, blower, and extruder in order. When the die outlet is uniform, you can wear gloves to slowly lift the tube blank, and at the same time, close the end of the tube blank, slightly open the air inlet regulating valve to blow a small amount of compressed air from the center hole of the mandrel, and then carefully guide it. Over stabilize the foam frame and herringbone, and penetrate the traction roller and guide roller until it is taken up.
