The blow molding process during the Second World War began to produce bottles. In the late 50’s, with the development of high-density polyethylene and blow molding machine,bottle blow moldingmachine technology has been widely used. The volume of the hollow container reaches several thousand liters, and now the production has been controlled by the computer. Suitable for blow molding plastic polyethylene, polyvinyl chloride, polypropylene, polyester, Hollow containers are widely used as industrial packaging containers. According to the method of manufacturing the preform, blow molding can be divided into extrusion blow molding and injection blow molding, newly developed multilayer blow molding and stretch blow molding, and then the blow molding machine also starts its journey. Now blow molding machine has become increasingly popular, but many manufacturers do not pay attention to its maintenance and maintenance, the following is the PET bottle blowing machine and maintenance:
1, in front of the bottle blowing machine of all kinds, must join all sorts of moving parts with smooth oil. (Robots, manipulators, rail clamping rails)
2, rocker arm (3 – 4) a day. Heater chains and small chains can be made once a month. Often look at the host reducer, heating reducer may be short of oil. Spindle bearings can be (3 – 2) plus a month.
3. Consumption inspection Before moving parts can be strong, loose screws, especially the central strong impact, whether it is the same part of the belt drive.
4 View high pressure air source, low pressure air source, power supply, water supply can be normal.
5 Check the emergency stop switch, safety door switch, maintenance switch maintenance and installation is normal.
6 view the warm head into the embryo, part of the work of the embryo can be normal. Insert the embryo, if not in place to adjust the pressure of the embryo to install the nut.
7. Check the lamp for possible damage and damage. Should be promptly replaced.
8. Check for possible leaks, flexibility, and flexibility of pneumatic components.
9, see the three bodies can also be leaked, can be blocked, the tank can be filled.
10. Plastic blow molding machine in the event of abnormal electromagnetic valve should be promptly cleaned
11 plastic blow molding machine mold must be regularly cleaned and polished.
12 open source pressure switch must be slow to prevent air flow into the solenoid valve too fast dirt, exhaust valve open at the same time 30 seconds to ensure clean air.
13 plastic blow molding machine must ensure that the mechanical parts are good, no one inside the machine, no foreign matter. Especially the handle position, was injured. Close the safety 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.
