1. Screw packing machine with poor sealing of screw packing machine
This problem is also relatively common. First of all, we have to find it from a simple place to see if the temperature reaches the sealing temperature of the packaging film. If it reaches the following, check whether the mold pressure of the screw packaging machine is reached. If there is no problem, the mold teeth are not. Occlusal or left and right pressures are different.
Solution: The first problem is to solve the problem by heating, the second problem is to pressurize, and the third problem is to re-align the mold, with one side as the benchmark, so that it can be right.
Second, the photoelectric problem of screw packaging machine
This problem also occurs more often. The problem of photoelectricity is generally manifested as the length of the walking bag will vary.
Solution: When the film is moving, does the photoelectric sweep the mark on the film, check whether there is dust on the optical eye, check whether the optical eye sensitivity is adjusted correctly, check whether the noise on the film is affected by the identification of the optical eye, if necessary Find a spot where there is no noise. If you can't find it, your packaging film can be thrown away.
3. The temperature of the screw packaging machine cannot rise
This question is relatively easy to judge, but it is still relatively rare for preliminary scholars. First, you need to check whether the fuse is damaged. Check whether the relay is damaged. Check it with a multimeter. If you don’t have a multimeter, use a test pencil. The next step is to see if the heating rod wiring is loose. If not, take down the heating rod wire and test the resistance. If the resistance is infinite, the heating rod will be over. If there is no universal meter, you will get one by one. Try again. There is also a thermocouple damage. This problem is easy to judge. Either a 1 is displayed on the far left side of the temperature control table, or the temperature has been jumping a lot. It can be solved by directly replacing the thermocouple.
4. The temperature of the screw packaging machine cannot be controlled
There are two reasons for this problem, one is that the temperature control meter is broken, and the other is that the relay is broken. First measure the relay, because this is slightly more bad.
5. The main motor of the screw packing machine does not rotate
First look at the fuse. If it is not damaged, check whether the relay of the main motor is damaged. If it is not damaged, it is the problem of the main board of the screw packing machine.
