 I would like to thank you for all your efforts to choose the correct atomizer for our spray dryer,High speed drying. The surface area of Raw Material liquid increased a lot after atomization through nebulizer, 95%-98% of moisture will be evaporated in high temperature airflow in a flash, only needs seconds time.


I really don't know how to thank you, you are my angel, Thank you very much. Super Fine Pulverizing this one is faster than other same power machine and is easy to operate and repaired.

How To Solve The Problem Of Labeling Machine Breaking

February 1, 2021
Latest company case about How To Solve The Problem Of Labeling Machine Breaking

When online printing and labeling machines are widely used in our daily life and production, sometimes the labeling opportunities may have problems such as broken labels. The more common broken labels are as follows. How to solve the broken labels on the labeling machine?

1. There are cracks on the edge of the bottom paper of the label: this situation is a relatively common label break. The principle is that after the self-adhesive label is die-cut and processed into a finished product, the bottom paper is generally left wider than the label. This setting is to facilitate the uncovering of the label when labeling. In the process of transportation and handling of labels, it is easy to crack the bottom paper on the edge of the label and cause small cracks, and the automatic labeling machine has a certain tension when labeling, so the label with a crack on the bottom paper edge is easy to be under tension. The label is broken due to the action of the force and the label is broken. In addition, improper adjustment of the rollers on the automatic labeling machine may cause the rollers to fracture the bottom paper at the edge of the label and cause labeling to break. Like the labeling broken tape caused by the roller crushing the bottom paper, the bottom paper will have more regular cracks. Therefore, check carefully when loading the label roll and choose label paper with no cracks.


2. Poor die-cutting: The quality of die-cutting also has a great impact on whether the labeling machine is easy to break. If the die-cutting pressure is too large, the bottom paper will be cut through and the bottom paper's tensile strength will decrease. Labeling broken tape. However, if the broken surface of the labeling tape and the bottom paper caused by poor die-cutting is relatively uniform, and the crack is at the position of the die-cutting line, we can appropriately adjust the die-cutting control screw to make the die-cutting force moderate.


3. Adhesive seepage caused by over-tight label rewinding: it is also one of the reasons for label breakage. If the finished label is rewinded too tightly, the adhesive in the sticker will be squeezed out, resulting in seepage and exudation. Glue will stick to the back of the backing paper to make the entire roll of labels difficult to loosen, which is especially obvious in summer. If the label is relatively narrow, the tensile strength per unit area of the bottom paper will not be too large, and the automatic labeling machine will have a certain tension during the labeling process. When a roll of labels with leaking glue is used for automatic labeling, it is very likely that the backing paper of the label will be removed by the tension of the labeling machine and the tension from the inside of the roll during the labeling process. Pulling off causes the labeling to break. The labeling tape breaks caused by this situation, because the bottom paper breaks irregularly due to the tensile force, so it is necessary to check carefully when the label is rolled.


4. The release layer is damaged: If the release layer of the label bottom paper (usually the silicone oil layer) is damaged, it will also cause the label to break. In the label breakage caused by this situation, the broken surface of the backing paper is mostly jagged. The main reasons for the damage of the release layer are defects in the production and coating of raw materials, and there are also scratches on the release layer due to improper techniques in the process of inspection and replenishment in the printing plant.
