Common problems and solutions for labeling machines

Common problems and solutions for labeling machines
There are various problems with labeling machines during use, among which the most common problem is poor labeling quality. As an operator, in addition to learning how to use the labeling machine correctly, you must also master some necessary troubleshooting methods. If the operator can understand the cause of the fault, the solution will be simple. Below, the editor will introduce the causes and solutions of such faults.
1. The label wrinkles horizontally during labeling:

Reason 1: The bottle shape is not good and is laminated into a spherical shape; Solution: Increase the scraper force or replace a good bottle.

Reason 2: The labeling speed is too slow or the assembly line speed is too fast; Solution: Speed ​​up the labeling speed or slow down the assembly line speed.

2. The label wrinkles vertically during labeling:

Reason: The labeling speed is too fast or the assembly line speed is too slow; Solution: Slow down the labeling speed or speed up the assembly line speed, that is, the bottle walking speed.

3. Causes and solutions for label wrinkles:

 Reason 1: The scraper is not flat; Solution: Replace a flat scraper.

 Reason 2: The label tape is too loose; Solution: Tighten the label tape appropriately.

 Reason 3: The stripping plate mouth is not parallel to the bottle surface; Solution: Adjust the stripping plate mouth to make it parallel to the bottle surface.

4. How to solve label bubbling:

 Reason 1: The stripping plate is not good (uneven); Solution: Replace a good and flat stripping plate.

Reason 2: The labeling speed is fast or the assembly line speed is slow; Solution: Appropriately reduce the labeling speed or speed up the assembly line speed.

Reason 3: The scraper is not good (uneven); Solution: Replace a flat scraper.

Reason 4: The label tape is too loose; Solution: Tighten the label tape appropriately.

5. Label advance and lag are unstable:

Reason 1: The correction mechanism failed to correct; Solution: Adjust the correction mechanism so that each bottle can be corrected correctly.

Reason 2: The bottle pressing mechanism presses the bottle too loosely or the scraper scrapes too heavily, and the bottle deflects during labeling; Solution: Increase the pressing force of the bottle pressing mechanism or reduce the force of the scraper so that the bottle will not deflect during labeling.

Reason 3: The angle between the stripping plate and the bottle surface is too small; Solution: Increase the angle between the stripping plate and the bottle surface, and then readjust the distance between the stripping plate and the bottle surface.

Reason 4: The stripping plate has touched the bottle; Solution: Adjust the distance between the stripping plate and the bottle so that the stripping plate does not touch the bottle;

Reason 5: The label belt is pressed too tightly; Solution: Loosen the label pressing sponge wheel.

The above is the solution to common faults of labeling machines, I hope it will be helpful to you.
