Horizontal packaging machine maintenance and maintenance

In Our eyes, the packaging machine has temperature and life. From the beginning to the conceptual design of the packaging machine, then to the technical design, then to study its manufacturing process, and then to manufacturing, installation, debugging and putting into operation, in fact, this is a process of nurturing life. The process of the user using the packaging machine is the process of interpreting the life cycle of the packaging machine. 大发888黄金版手机登录 has been advocating high-efficiency and low-cost preventive maintenance, strengthening the maintenance and maintenance of packaging machines, so that the packaging machines are in an efficient operation state, give full play to their effectiveness, prolong their service life, and obtain the best economic benefits for users and enterprises.
From the beginning of this issue, we will introduce how to carry out efficient maintenance and maintenance of packaging equipment according to the components of the horizontal packaging machine. Since the beginning of summer, most parts of our country are hot and rainy, the air is hot and humid, and electrical components failures frequently occur in this season. First of all, I will introduce the maintenance and maintenance of the electrical components of the packaging machine.

1. The exterior of the cabinet is clean and tidy, and the touch screen on the panel, the handle of the main power switch, the indicator light, the operation button, and the door and door lock are intact.
2. The cooling element (cooling fan) in the cabinet works normally.
3. The appearance of the electrical components in the cabinet is clean, free of dirt and defects, and there is no irrelevant sundries in the cabinet, especially metal objects.
4. The electrical switches in the cabinet are marked correctly and completely, and have not fallen off.
5. The electrical appliances in the cabinet are fastened firmly, the leads are neat and tidy, and the lead connectors are not loose (including the grounding point), or there are safety hazards such as overheating, discoloration and aging.
6. Without the approval and permission of the equipment department, it is strictly forbidden for anyone to modify or adjust the adjustment and setting of the parameters of the controller (such as inverter, servo drive, etc.), and it is strictly forbidden to change the electrical circuit at will.

1. Each control line is free from oil pollution, damage, overheating, insulation aging, chemical corrosion damage, etc.
2. The control lines are neat and orderly, and there is no hidden danger of mechanical parts interference.

1. Check whether the PLC wiring is good and reliable, and there is no aging loose.
2. Some types of PLCs (Schneider, Mitsubishi, etc.) are equipped with batteries, and it is necessary to regularly check the power alarm indicator on the PLC.
3. If the equipment is out of production for a long time, it is necessary to power on the equipment normally for no less than 2 hours every day.

1. Because each sensor device is fragile and has a high fault point, it needs to be checked to prevent other mechanical action failures or accidents due to uncleanness, loosening, failure, etc.
2. Check that the appearance of each sensing element is clean and in good condition.
3. Check the tightness of each sensor element.
4. Check whether the action of each sensing device is sensitive and reliable.
5. Check whether the lead wires of each sensing device are in good condition.

1. The output execution parts (such as motors, relays, contactors, solenoid valves, electric heaters, etc.) are all vulnerable parts and need to be inspected frequently.
2. Check the appearance of such devices for cleanliness.
3. Motors, transformers, electric heaters, etc., need to check whether their working current is normal.
4. The appearance of the motor is good, there is no oil and dust accumulation, and the running and running sound is normal.
5. Check whether the wiring of such devices is good and reliable, and there is no aging loose.

fault phenomenon
Cause Analysis
Suggested exclusions
Color mark capture is unstable
1. The color mark detector is not set properly
Reset the patch detector
2. The optical fiber is not fixed
Re-attach the connecting fiber
3. Inconsistent distance between roll film color labels
Replace roll film
4. The color of the color scale is too close to the background color
Replacing rolls with significant differences in color contrast
5. The distance between the color mark detector and the color mark is wrong
Adjust the distance from the color mark detector to the color mark to an appropriate position
6. The encoder connection is broken or loose, causing the encoder angle to change abnormally
Reconnect the encoder
7. The resistance of the packaging film is abnormal
Check the machine for film jamming and eliminate it in time
8. The color mark detector is not in the correct position for the color mark
Adjust the color mark detector to the position of the color mark
The machine does not stop normally
1. The encoder is damaged
Replace the encoder
2. The encoder and the spindle are not well connected
reset the connection
3. The encoder input and output lines are abnormal
reset the connection
Machine won’t start
1. The emergency stop button is pressed
reboot after reset
2. The switches are not fully opened
Open the switch in the electrical box
3. There is an alarm signal
Find the cause of the alarm first, then eliminate the alarm signal
Inverter abnormal alarm
1. The external voltage is abnormal
Check the “Inverter User’s Manual” and solve the problem through the touch screen operation
2. The neutral circuit is abnormal
3. The output voltage is abnormal
Thermostat display abnormal
1. The temperature controller is damaged
Replace the thermostat
2. Thermocouple damage
Replace the thermocouple
3. The heating rod is damaged
Replace the heating rod
4. Broken or loose wiring
Reconnect the wiring
5. The positive and negative poles of the thermocouple are wrongly connected (the temperature controller shows a negative value)
Swap the positive and negative poles
Display does not show
Poor connection between display screen and PLC
reconnect
