Blown film machine operation procedure

Film blowing machine operation procedure:

1. Turn off the main power switch of the machine, check whether there is any leakage of electricity, preheat the barrel and mould according to the set process temperature, when the barrel temperature reaches the process temperature, keep warm for more than 20 minutes to ensure that the temperature of all parts of the barrel is even. Only if there is no abnormality found, the oil pump can be started formally, and the screen will show "motor on" before running, and check whether the safety door works normally.

2. Manually start the screw rotation of the film blowing machine, check whether the screw rotation sound is abnormal and stuck.

3. The operator should use the exit, if the exit travel switch is out of order, it is not allowed to start the machine, and it is forbidden to operate the machine without using the exit (cover).

4. Cover and fix all kinds of electrical, hydraulic and operating equipment rotating parts of the cover and shield.

5. For off-duty operators, without permission, no one shall press the button and handle, two or more people shall not operate the same film blowing machine at the same time.

6. When repairing the film blowing machine or cleaning the mould for a long time (more than 10 minutes), it is necessary to back off the injection seat so that the nozzle leaves the mould and turn off the motor. When the maintenance personnel repair the machine, the operator shall not leave the post.

7. When the body of the machine into the machine tool or open the mould, cut off the power supply, avoid the dangerous area. When cleaning the nozzle rubber tip, it is not allowed to clean it directly by hand. Iron tongs or other tools should be used to avoid injury, climbing and placing objects to prevent electric shock and fire.

8. It is not allowed to use metal and electric poles and poke the hopper with force when the hopper is not discharging material to avoid damaging the screen, screen cover and magnet frame inside the hopper. If the screw rotates, it is easy to cause serious equipment damage due to metal rods involved in the barrel.

9. When abnormal equipment noise, odour, sparks, oil leakage are found in the operation of the machine, the machine should be stopped immediately and reported to the relevant personnel immediately, explaining the failure phenomenon and possible causes.

10. Pay attention to the safe operation of the film blowing machine, do not use any reason or excuse to make any operation mode that may cause personal injury or equipment damage.

The main features of the film blowing machine

1, blown film machine group is suitable for blowing low density polyethylene and linear density low polyethylene as well as plastic for film, widely studied and applied in our country food, clothing, textiles, daily necessities and other civilian goods and industrial products packaging. Raw materials need to go through different formulation technology can improve the production of pearlescent film, degradation film.

2. Screw and barrel are made of 38CRMOAL, nitriding treatment, precision machining, high hardness, corrosion resistance, durable.

The die head is plated with hard chrome, the structure is spiral mandrel type, the melt is extruded evenly, the blown film is smooth, the structure of the air cooling device is labyrinth type, the air out is even.

4. The winding device adopts pressure friction winding or centre winding, which is regulated by torque motor, smooth winding and easy to change the wire.
