Daily maintenance and maintenance methods of bottle blowing machine equipment

The blow molding process was used to produce vials during the Second World War. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of the hollow container can reach thousands of liters, and the current production has adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The resulting hollow containers are widely used as industrial packaging containers. According to the manufacturing method of the parison, blow molding can be divided into extrusion blow molding and injection blow molding. Plastics, the newly developed multi-layer blow molding and stretch blow molding, followed by the blowing machine equipment also began its journey. Now the bottle blowing machine has become more and more popular, but many manufacturers have not paid attention to its maintenance and maintenance. The following is the maintenance and maintenance of the bottle blowing machine:

1. Before turning on the plastic bottle blowing machine every shift, lubricating oil must be added to each movable part once. (Manipulator, manipulator guide rail, mold opening and closing guide rail)

2. The swing arm can be added once (3-4) days. The large chain and small chain of the heating machine can be used once a month. Always check whether the reducer of the main engine and the reducer of the heating machine are short of oil. The main engine bearing can be added once a month (2-3).

3. Before consumption, check whether the moving parts are strong and whether the screws are loose and scattered, especially whether the center with strong impact force and the belt drive part are abnormal.

4. Check whether the high-pressure gas source, low-pressure gas source, power source, and water source are normal.

5. Check whether each emergency stop switch, safety door switch, maintenance installation detection switch is normal.

6. Check whether the heating head enters the embryo, and the embryo drops are working properly. If the inserts are not in place, you can adjust the mounting nuts for the inserts.

7. Check whether the lamp tube is damaged or broken. It should be replaced in time.

8. Check whether the pneumatic components can leak air, and whether the actions are smart.

9. Check whether the triplet is leaking abnormally, whether it is blocked, and whether the water cup is too full.

10. When the solenoid valve of the plastic blow molding machine encounters abnormalities, it must be cleaned in time

11. Plastic blow molding machine molds must be cleaned and polished regularly.

12. When opening the upper and lower pressure air source switches, you must move slowly to prevent the air flow from being too fast and the dirt will be blown into the solenoid valve. At the same time, open the exhaust valve for 30 seconds to ensure that the air is clean.

13. When starting the plastic blow molding machine, you must make sure that the part of the machine is in good condition, that there is no one inside the machine and no foreign matter. Especially the status of the handle, so as not to hurt. At the same time, close the safety door.

14. When starting the machine, the motor must be started first, and the heating machine must be started with a delay of 30 seconds to prevent voltage shaking. Before starting the heating, make sure that the cooling water is turned on.

15. After the heating is started (2-3) minutes, wait for the oven temperature to rise evenly, and then press the embryo button. At the same time, the blowing must be turned on, otherwise the blowing will not be possible.

16. When the plastic blow molding machine is in operation, it is necessary to pay close attention to whether the machine can make abnormal noises, so as to find out early and stop the machine in time to solve it early.

17. When there is an emergency, you can press the emergency stop button to press the brake. Then, based on the analysis of the on-site status, the problem was solved quickly.

18. After normal operation, do not extend any part of the body into the machine to avoid the manipulator injuring people. If the machine has abnormal noise, it can slow down and stop the observation.

19. After normal consumption, the operator must always observe the quality of the bottle, so as not to affect the quality of the bottle blowing due to the shaking of the voltage or other reasons.

20. When repairing, you can press the defect repair button on the touch screen to ensure safe repair. If you need to manually observe the actions of each cavity individually, please pay attention to the status of the robot. At the same time, you must understand the function of the individual button, and then take action. Make sure that mistakes cause unnecessary trouble.

twenty one. After each repair, you must clean up tools and screws to avoid leaving them in the machine and affecting the normal operation of the machine.
