If you have no relevant operating experience but want to master and use a pre-made bag packaging machine in a short time, then this article is for you. Written from the user’s perspective, it aims to help factories and employees who are buying and using pre-made bag packaging machines for the first time.
Pre-made bag packaging machine is a device that automatically opens pre-made bags and loads materials into them. It streamlines the packaging process, making it faster and more efficient.Learning how to disassemble and install a pre-made bag packaging machine is crucial for proper maintenance and operation. Here’s a step-by-step guide to help you get started:
Installation
When the premade bag machine is transported to your location, in addition to the user’s manual, the machine is usually packed in a wooden cases. At this time, it should be handled with care to avoid collision and inversion, and two machines are not allowed to be stacked. When installing, a large enough space should be reserved around to facilitate the adjustment of product specifications, maintenance, lubrication and maintenance operations. Surround the wooden box and remove the nails around the wooden case. Adjust the balance of the machine by adjusting the supporting legs to make the basic level of the machine to ensure the stability of the machine.
Confirm whether the voltage is consistent with this machine. After the power is “on”, if the indicator light is on, the main switch on the lower right side of the box will turn “on”. The average input voltage is correct and the machine can start to work normally.
Otherwise, it means that the input voltage is incorrect and the phase sequence is inconsistent with each other. The input power voltage should be checked or any two-phase line of the three-phase power line should be switched.
power supply connection and start-up
When our machine is finished and before it is packed and shipped, it is usually tested according to the packaging materials provided by the user.The usual testing process is as follows:
Turn on the required switches on the touch screen, turn on the thermostat, set the temperature of the sealing head on the operation board until the set temperature is reached. (The temperature is usually determined according to the user’s packaging material) Press the start button, the machine slowly enters the running state, and when it is determined that the machine is operating normally, press the start button, and the machine is working properly. When it is determined that the machine is operating well, set the filling weight according to the operating instructions (manually check the filling system if necessary), and when taking bags continuously, the machine will open the feeding screw and valve to start feeding and packaging.
Working environment :
Working temperature：5-35°C
Relative temperature≤85%
Voltage：380V±20V（3 phase/4 wires）/220V
Operation and production
Next you may ask, how to operate the machine?
First you have to start the machine. Before starting,check whether the main packaging machine and supporting equipment are installed normally, check whether the power supply is in normal contact, and check the voltage (220/380).Tracheal examination, whether the air pressure is normal (0.62).
Then you need to adjust the bag slot according to the size of the bag, adjust the size of the bags needed in each station, open the power supply to select the required energy, and put the bags into the bagging trough neatly. Press ”ON” to observe whether each station is working properly. Open the supporting equipment to cooperate with the operation.
Then, you can control the whole process of bag packaging on the PLC display screen, and enter the function page by selecting your language.
Buttons turn GREEN means ON, turn PURPLE means OFF.

Now that you have understood the basic parameters, do you think it is not difficult to operate a machine? Next, we will talk about how to set up the machine if you need to change the bag type of packaging.
machine adjustment while changing of bag size
Usually, there is a pre-made bag slot on the left side of the machine. During production, pre-made bags are placed into the slot, and the machine will automatically take out the bags and pack the materials inside. When manually placing the pre-made bags into the bag slot, please make sure the prefabricated bag flat placed well and then gently press down the bag presser block. As shown in the figure 5-2 below:
Upper conveying and bag stretching device adjusment:
This adjustment is required only if the package size is changed. As shown in Figure 6-12, just adjust the position of the sliding axle seat of the extension bag zone, and tighten the fixed bolt when the adjustment is finished.
You can choose the positions of different hole to set sealing bag position so as to achieve the best effect on the smoothness of the sealing. But it should be noted that after adjustment, the location of the two side expansion of bag must be corresponding.
Common problem and Machine maintenance
After your machine is put into use, regular cleaning and maintenance can effectively extend the life of the machine.The surface of the machine needs to be cleaned regularly according to the materials you are packaging and the operating time. If you are packaging food, you need to sterilize it.
- Clean the surface of the heat sealing block with a copper wire brush every day, and keep the tooth surface clean so that the sealing edge of the bag can be sealed and leveled.
- Vertical and horizontal join axes and other rolling axis should keep clean, every week
- Regular cleaning of air systems and vacuum system filters.
- Electronically control system cleaning work once a week.
If the machine has some faults during use, you can refer to the following methods to repair it:
If your machine cannot start, there may be several reasons:
- No power input, the indicator light is off at this time
- You may have pressed the emergency stop button
- The machine’sconverter is overloaded or the parameters are wrong
- The machine isin automatic operation mode
In the above situations, you can use the following methods to troubleshoot:
- Check power supply and circuit breaker in electric box.
- Reset emergency stop button
- Turn off the power switch and turn on in 2 minutes.
- Start the manual mode on the touch screen
When your machine successfully boots up, but can’t work? There may be these problems:
- Machine is in automatic runing mode（We have discussed above how to deal with this problem，start themanual mode on the touch screen）
- Machine is in the output alarm state,the way we deal with this is to check the Alarm signals such as temperature exceeding difference
When you successfully start the machine and it is running, but it suddenly stops, don’t worry, we will talk about the solution，but first you need to find the problem.These may be:1. Motor overload protection has started，2. Abnormal or excessive temperature，3.No power.
What you need to do now is,Check thermal relay, motor load and mechanical overload.
- Check the heating rod voltage and temperature sensors.
- Check whether the input power and load switch are tripped.
FAQ
1.Q:What if my bag doesn’t seal firmly after filling it with material?
A:This could be due to poorly adjusted of bag spreading device, or the bag being too small and having material crusting on the upper seal, or you increasing the bag speed without increasing the temperature of the machine.
Obviously, you need to take some action.You should reposition the expansion bag, check the bag capacity to see if it meets the requirements, and clean the dirt off the sealing block. If you want to increase the packaging speed, you should increase the sealing temperature accordingly.
2.Q:Why is the bag sealed unevenly?
A:It may be a problem with your packaging materials. You need to choose more reasonable packaging materials. Or you set the sealing temperature too high. Set a temperature suitable for packaging.
- Q：Why doesmachines make noise?
A:Because the screws are loose and the oil lubrication equipment is insufficient. You need to regularly refueling and inspection of moving or vibrating parts screws.
