Pay attention to some temperature control during the process of using the bottle machine to ensure the manufacture of suitable plastic bottle.So what should I do if the bottle blower fails?How to maintain the daily maintenance of the bottle blower?
How to install the bottle blower
1. The layout of the machine
The layout of the machine in the plant should meet the convenience of replacement molds and maintenance.Generally, there is a space of 1 to 1.5 meters in four weeks, and the two machines should have a distance of about 2 meters.
2. Requirements for installation foundation
In order not to vibrate at work, the machine should be placed on the basis of cement.The base thickness is ≥459mm, the concrete label is not less than 200#, and the level of the foundation is 1/1000.The exposure part of the foundation pit should be prepared for a suitable cover (installed in the tunnel pipeline) to prevent accidents.The installation foundation bearing capacity is not less than 8MPa.
3. Installation order
The installation is divided into fixed installation and mobility installation.
1) The fixed installation is to transport the machine to the basics, install the foot screws, initially adjust the level, and then irrigate concrete in the screw hole of the foot.It can also be fixed directly on the basal ping.The machine tilt angle is not more than 3 °
2) The method of refined levels is to use the horizontal instrument to measure on the upper plane and plug -inserted tail tail slot of the lock -locking template. After the vertical horizontal level is adjusted, the screws of the foot are evenly tightened.
3) Mobilization installation can be relocated at any time.Just place the shockproof pads (standard size, but non -music standard accessories) placed in the place where the foot bolts are empty, use the horizontal ruler to the upper edge of the template, correct the level, adjust the shockproof pad, and then fix the nut.The machine tilt angle is not greater than 3 °.

How to maintain the bottle blower
1. Before the plastic bottle blower is turned on each shift, it must be added with light oil once in each activity component.In
2. Plag arm (3-4) can be added once a day.Big chain and small chain can be once a month.Regularly check whether the host reducer and heating machine can be lacked.The host bearing can be added once (2-3).
3. Check whether each motion component can be strong before consumption, and whether the screws can loosen and zero, especially the center with strong impact power, and the belt transmission can be abnormal.
4. Check whether high -voltage gas sources, low -voltage gas sources, power supply, and water sources are normal.
5. Check the switching switches, the safety door switch, and maintain whether the installation and detection switch can be normal.
6. Check the embryo in the grocery head, whether the local work of the embryo can be normal.If the embryo is not in place, it can be conditioned by conditioning the embryo to install the nut.
7. Check whether the lamp can be damaged and break.Change it in time.
8. Check whether the pneumatic components can leak air and whether the action can be flexible.
9. Check whether the three -united body can be abnormally leaked, whether the infarction can, and whether the water storage amount of the water cup can be too full.
10. When the electromaging valve of the plastic bottle blowing machine is abnormal, it should be cleaned in time.
11. Plastic bottle blower molds must be cleaned regularly and polished.
12. When turning on the upper and lower pressure gas sources, it is necessary to delay the movement to prevent the gas from being blown into the solenoid valve too fast. At the same time, open the exhaust valve for 30 seconds to ensure that the air is clean.
13. When the plastic bottle blowing machine starts, it must be convinced that the mechanical is locally good, no one inside the machine, no foreign body.Especially shake the position to avoid hurting people.At the same time, close the Pinganmen.
14. When starting the machine, start the motor first, and delay the heating machine for 30 seconds to prevent the voltage from shaking.Before starting heating, you must have the cooling water.
15. After the warm start (2-3) minutes, the temperature of the oven rose average, press the embryo button.At the same time, the bottle is turned on, otherwise it will not blow the bottle.
16. Plastic bottle blowing machine must pay close attention to whether the machine can have abnormal noise when it is running.
17. When there is an emergency, you can press the emergency stop button to brake.Then use the reason for the composition of on -site conditions to find the problem quickly.
18. After normal operation, do not reach into the machine in any part of the body to avoid robotic hands.If the machine has abnormal noise, it can be decelerated.
19. After normal consumption, the operator must often check the quality of the bottle, so as not to shake the voltage or other reasons to affect the quality of the bottle.
20. During maintenance, you can press the touch screen maintenance button to ensure safety maintenance.If you need to manually check the movements of each mold cavity, please pay attention to the position of the robotic hand.At the same time, be sure to clear the role of separate buttons, and then move again.Make sure that the accidental action causes no need to worry.
21. After each repair, be sure to liquidate the tools and screws, so as not to leave the machine and affect the normal operation of the machine.
