Common problems of mask making machine

For the mask manufacturers are headache of the difficult problem of debugging the mask machine, by CJR's tuning machine technical staff together to discuss, for you to summarize the summary of debugging the 8 major technical difficulties and solutions of the mask making machine, here to share the experience about debugging the mask making machine, I hope it will help you.

1、The length of the ear strap is not enough:

The main reason is that the wire feeding mechanism is caused by a part of the wire jam, or the stroke cylinder stroke is not enough.

Focus on investigating the wire feeding mechanism and wire wheels and other components, ear belt is not in the three wire wheels, ear belt wire holes have batch front, ear belt knotted, ear belt feeding sensor is bad, ear belt feeding motor does not move, ear belt feeding sensor guide wheel rising stroke short and other problems.

2、Ear band can not be welded:

1) Generally is not working ultrasonic caused by, or welding pen stroke is not enough, adjust the cylinder stroke of the welding pen to the appropriate position can be, the ultrasonic problem is more complex.

2) Suggest the following points to investigate, first restart the ultrasonic, check whether the power supply is abnormal, and check whether the frequency is normal, you can determine the ultrasonic frequency search.

3) Setting method: transfer to the parameter setting interface, working mode: automatic, press the start button can search for matching frequency by itself, repeat the search three times to take the middle value of manual input frequency can be.

Long working hours caused by poor heat dissipation of the transducer is not the main problem of welding, you can use the above method to adjust.

3、Welding is not firm:

Welding time is too short, welding pen cylinder stroke adjustment, insufficient air pressure (generally to 0.4mpa or more).

4、The weld joint is too heavy:

The welding time is too long, the power is too high, and the welding pen cylinder can not be adjusted.

5、a point of welding is too heavy or not firm：

Please adjust the level of the die and the welding pen

6、The ear belt welding position is not the same：

Put the piece when put not good, conveyor chain action to bring the mouthpiece deviation, ear belt rotation cylinder stroke adjustment, ear belt wire head bending, etc.

7、Ear band welding wire head is too long or too short：

Earband stretching from cylinder adjustment, general buffer, and coupling screws loose caused by the change in the position of the scissors.

8、scissors cut constantly：

Scissors cylinder failure, insufficient air pressure, scissors blade wear, loose scissors screws, scissors spring damage, etc.
