Several common problems of bag making machine and countermeasures

The bag making machine is a machine that makes various plastic packaging or other material packaging bags, and its processing range is various sizes of plastic or other material packaging bags of different thicknesses and specifications. Of course, in the process of using the bag making machine, there will be many problems. This article is to help you clear away those troubles about the failure of the bag making machine.
1. What should I do if the cold cutter of the flat mouth machine keeps cutting?
When the cold cutter of the flat cutter always cuts continuously, check whether the cutter is sharp and whether it needs to be re-grinded; check whether the balance of the upper and lower cutters is appropriate. balance.
2, what should I do if the bag size is different if the length of the bag is different if the flat mouth machine cuts three or more
Put a layer on the rubber roller behind the thin film to make it even with other materials.
3. What caused the spring of the leveling machine to break?
The self-adhesive strip is not stuck in place, and the spring will be broken when it is rolled up and rolled. The self-adhesive strip must be stuck properly during operation. There is another reason, the material is not neat or stuffed into the rubber roller, causing the spring to break irregularly.
4. What should I do if there is a big difference between the two sides of the edge of the bone bag making machine?
The aluminum pressing roller needs to be adjusted well and adjusted to be pressed on both sides of the sealing edge to avoid this situation.
5. What is the reason why the self-adhesive strip cut by the side sealer often sticks to the conveyor belt?
The self-adhesive strip is misaligned and stuck to the conveyor belt. The self-adhesive position of the rear edge correction machine needs to be debugged, and the edge correction electric eye must be placed in the self-adhesive position to correct the edge to prevent it from running out.
6. ​​What is the reason why there are burrs on the OPP edge or the explosion-proof edge will be rotten?
The hot knife and the suction arm are not adjusted properly. The normal situation is that the hot knife cuts down to 2 cm, and the suction arm sends the material out.
7. What should I do if the side sealing machine cuts out the length of the finished product?
The pressure spring is not compressed, causing the rubber roller to slip, or the cleat clamp behind is too tight, it needs to be adjusted properly.
8. What should I do if the flat-end machine is blocked in front of the cold cutter?
This situation should be because the bag is too strong. Use a rubber band to stick a small piece of paper on the screw on the knife beam, and the cut out tape will jam the bag out at the same time.
9. What should I do if the film blowing machine discharges and rewinds with uneven thickness and one side is thin?
Need to wrap the electronic rack on the thin side until it fits.
10. What should I do if the printing bag is not fed smoothly and the electric eye is not sensitive enough?
First check whether the electric eye is used correctly. The electric eye has a certain degree of sensitivity to color. If the bag is single color, use blue, heavy color use red, and red can be used for single color and heavy color. The roller under the electric eye of the edge correction machine should be sprayed black. If the bag is of single color and heavier, it is best to use a white background.
11. How long has the new machine not cut the bag, and the cutting knife cuts the thinner film continuously, or what should I do if it cuts constantly in a certain place
This situation may be caused by the fact that the upper knife beam slider has been running-in for a period of time, resulting in too large a gap between the slider and the copper pad, which will cause the cutting knife to cut continuously. The top seam (M6 inner corner) of the copper pad block can be adjusted until the upper knife beam slider cannot be moved by hand, but it cannot be adjusted too tightly. When starting to cut 15-20 sheets per minute, the upper knife beam did not vibrate significantly to prove that the gap was tight. In addition, the spring pressure of the upper knife beam can be adjusted.
12. What to do if the sealing of the flat mouth machine and the R machine is not firm
①Check whether the hot knife is stuck: the sealing of the hot knife is not smooth, and the sealing will sometimes be firm and sometimes not firm.
②Check whether the knife edge is deformed or bent due to heating. The inspection method is to turn the hot knife to the bottom position, when the hot knife is about to be connected
When touching the silicone roller or silicone plate, judge whether the hot knife is bent or not by the light transmission method. If there is any bending, repair the flatness of the knife edge
③Check whether the film has too strong electrons. Test it with a film that has not passed electrons. If it is sealed and cut, see if there is any obvious change in the sealing.
