The blow molding process during the Second World War, started for the production of bottle. In the late 50s, with the development of high density polyethylene and blow molding machine, blow molding technology has been widely used. The volume of the hollow container is up to several thousand liters, and now the production has been controlled by computer. Suitable for blow molding plastic polyethylene, polyvinyl chloride, polypropylene, polyester, the hollow container is widely used as industrial packaging containers, according to the method of making preforms, blow molding can be divided into extrusion blow moulding and injection blow molding, newly developed multi-layer blow molding and stretch blow molding, then blowing machine also began its journey. Now blowing machine has become more and more popular, but many manufacturers do not pay attention to its maintenance and maintenance, the following is Pet bottle blowing machine and maintenance:
1 before the opening of the Pet bottle blowing machine every class, must be in the various activities of the parts plus a smooth oil. (manipulator, manipulator, rail clamping rail)
2 the swing arm (3 – 4) a day. Heating machine chain and the small chain can be once a month. Often look at the mainframe reducer, heating reducer can lack of oil. Host bearings can be (3 – 2) plus one month.
3 consumption check before the moving parts can sturdy, screw loosening body, especially the center of strong impact, whether the same local belt drive.
4 view the high pressure air source, low pressure gas source, power supply, water supply can be normal.
5 check the emergency stop switch, safety door switch, maintenance and installation of the detection switch is normal.
6 view plus warm head into the embryo, partial work out of the embryo can be normal. Insert embryos if not in place to adjust the pressure of the embryo to install the nut.
7 to see if the lamp tube can be damaged, broken. Should be replaced in a timely manner.
8 check the pneumatic components can leak, the initiative is flexible.
9 see three of the body can also leak, can be blocked, the water storage can cup is too full.
10 plastic blow molding machine electromagnetic valve in the event of a strange, should be promptly cleaned
11 plastic blow molding machine mold must be cleaned regularly, polishing.
12 open source under the pressure switch must be slow action, to prevent air flow too fast dirt blown into the solenoid valve, the exhaust valve is opened at the same time 30 seconds, to ensure clean air.
13 plastic blow molding machine must be sure that the mechanical part is good, no one inside the machine, no foreign body. Especially the handle position, lest hurt. At the same time to close the security door.
14 start the machine must start the motor, delay 30 seconds to start the heating machine, in order to prevent the voltage shake. Before starting the heating must be sure that the cooling water is not open.
15 minutes after the start of heating (2-3), when the oven temperature rise evenly, press the button in the embryo. At the same time, the power to open the bottle, or not blowing the bottle.
16 plastic blow molding machine must pay close attention to the operation of the machine can have the same noise, to achieve early detection, timely stop early settlement.
17 in case of emergency, press the emergency stop button, pressing the brake. And then according to the analysis of the causes of the scene, to find a quick solution to the problem.
18 after the normal operation, the body of any part of the machine should not be put into the machine so that the robot does not hurt people. If the machine has abnormal sound can be slowed down after the observation.
19 after the normal consumption, the operator should always observe the quality of the bottle, so as not to shake the voltage or the rest of the reasons to affect the quality of the bottle blowing.
20 maintenance, according to the touch screen, the shortcomings of the repair button to ensure the safety of maintenance. If you need to observe the action of each mode by hand, please pay attention to the position of the robot. At the same time, be sure to understand the role of the button alone, and then in action. Make sure that mistakes are caused by unnecessary trouble.
21 after each repair, must be sure to clean up tools and screws and the like, so as to avoid the legacy of the machine, affecting the normal operation of the machine.
