Share the operation of the blow molding machine

Precautions before starting:
1. When the machine starts to warm up, first turn on the cooling water of the barrel. The heating time is when the temperature of each section reaches the set process temperature, the material can be squeezed after holding for 30 minutes. During the heating period, the set temperature cannot be increased to speed up the heating. Temperature time, because the surface temperature is reached but the internal temperature of the plastic has not actually reached the process temperature (the plastic is not completely melted). At this time, the extrusion will load the motor and gear box, causing the motor and gear box to be easy Damage; it will also cause material leakage at each locking part of the die; record the time of each heating and the temperature rise of each section, and if the temperature is not correct, report to the monitor or mechanics for repair in time, and register the repair record; check the compressed air pressure Can it reach 0.6Mpa≤air pressure≥0.8Mpa. Check whether the screws and nuts of the components are loose. If they are loose, tighten them. If necessary, report to the mechanic for inspection and fixation. Check the pneumatic triplex. If the amount of oil in the lubricator is insufficient, add it in time.
2. The conditions for starting up, if the left shelf is put on the shelf, the conditions are: the left pen is inserted back to the pen until the proximity switch is on, the left mold is opened until the proximity switch is on, and the right shelf bottom stop proximity switch is on; if the right shelf is put on the shelf, the condition is: the right pen is inserted The pen-back stop proximity switch is on, the right mold opening proximity switch is on, and the left frame bottom stop proximity switch is on;
The condition for unloading when going fully automatic is that the mold closing stop switch must be on and the above required conditions can be activated, and the pen insertion must be aligned and vertical; the rotary knife holder must be adjusted horizontally, so that the bottle mouth can be cut flat, and the rotary knife To be on the same line, flat pads and spring pads must be installed on the rotary knife bar, so that you don’t need to lock it too tightly, you can also adjust the angle of the knife conveniently and easily, and you must also ensure the completeness of the stripper sleeve. You cannot pull the bottle with your hands.
3. During the production of the machine, we must ensure that the material tube is as straight as possible, and the mold must be clamped in the middle of the material tube when the mold is closed, so as to ensure that the wall thickness of the bottle is uniform, and the length of the material tube is appropriately adjusted with the balance screw And throttling screws, you can’t turn off the heating or lower the set temperature during production. Always check the pressure of compressed air, the maximum pressure of the action (clamping high pressure), machine cycle time, blowing machine time, and make a record to ensure that every shift There is a record; look at the temperature of each section and the weight of each bottle number, and make a record to ensure that there are three to four records per shift; if there is an abnormality, you must report to the shift leader or mechanics for repair and register the repair record.
