Rotary die cutting machine Learning is a process of accumulating experience. After encountering many problems, solutions and skills are accumulated after solving many problems. And these are things that can be discussed.
What problems often occur in the production process? What can be done to prevent it?
- Materials are not found after use
The rotary die cutting machine has this problem in the years just introduced into China, and there is basically no need to worry about it at this stage, because now all the circular knife machines of Xiaoniu have a cut-off reminder function, when the material reaches a certain critical value, the machine will automatically alarm, and the material will automatically stop after being disconnected, and basically there will be a large number of defective products caused by the cut-off.
Of course, it is also necessary for the boot master to know well, calculate each material on the machine, and line it up from less to more in the heart, so as to clarify which to focus on first.
2. The material connection is crooked or unreliable, or wrong
These problems are basically caused by unproficiency, and the solution is very simple: keep practicing, and master the new connector until it is ready, keep practicing.
3. Product shrinkage
This problem is basically due to the die-cutting of materials with elasticity, under normal circumstances, reducing the tension of the material or adding the clasp ring to fix the raw material, and not putting the tension compound can solve the problem.
What's more, now that the Xiaoniu machine has a feeding function, this problem with most materials no longer exists.
4. Drop the tablet
The causes of falling pieces are various, and the following can avoid a variety of falling pieces:
Check the support ring for foreign bodies and clean the support ring;
Check whether there is a problem with the mold, repair the mold;
Check whether the foam of the pad knife is wrapped with glue or non-elastic, and replace the foam;
Whether the knife is flattened, the new press and the knife press.
5. Stick the mold
The most likely is that the foam needs to be replaced, or add teflon, silicone foam, release agent, or release film to the foam, etc. More complex methods can be directly opened the anti-stick coating mold, or apply silicone in the mold knife cavity (similar to glass glue).
6. Offset or socket instability
The most direct solution is to adjust the ratio of discharge tension and press the new roller to flatten. Focus on checking the tension of the retracting and retracting shaft, and correct the tension of the retracting and retracting shaft.
7. Dirt
Most of the production affected by dirt occurs in the die-cutting of non-woven fabrics and foam materials, which requires cleaning the machine, gears, rollers and other places that are easy to store dirt and dirt before each machine and after shutdown, and ensuring good surrounding 5S at any time during production to measure whether the production environment is up to standard.
8. Glue overflow
In case of overflow, it is necessary to pay attention to reduce the pressure of the pressing roller and the tension of the receiving product, timely clean the mold blade, replace the thinner foam or add the release agent.
9. Corners cut constantly
This problem first look at the tool, determine whether the tool is sharp enough, if not, please repair the knife as soon as possible;
Then look at the material, whether it is damp, hardening or other changes, if so, please pay attention to protect the material;
In the case of ensuring that the tool and material are no problem, it may be that the roller is too small, the corner is a little big, the contact surface is small and not easy to cut off, and the replacement of a larger roller can solve the problem.
10. Poor waste disposal
Method, replace foam; Adjust the discharge Angle; Adjust the ratio; Adjust the waste tension.
Of course, there are some other problems and a lot of treatment methods, in this is not a list, the problem treatment method is nothing more than personnel, machinery, accessories, materials, process methods and environment, I hope you in the use of everything smoothly, if there are any difficult problems, welcome to the calf (+86 17734565982) together to discuss.
