　　A Guangdong label‑applying machine manufacturer explains: Why does the labeling machine have suction but fail to pick up labels?

　　Currently, many daily‑use chemical products are labeled with brand logos, product information, order details, and more. Labeling machines can print these labels on the spot, enabling fully automated, rapid application right at the factory. Every step in the process is critical, requiring meticulous attention—especially when it comes to the labeling machine.

　　Typically, the standard control panel of a labeling machine is flat and features small circular holes that, based on its internal structure, use vacuum suction to pick up labels. During operation, if the issue occurs with a new machine, it could be due to improper adjustment or a design flaw; in such cases, re‑adjustment or contacting the manufacturer for replacement may be necessary. If a normally functioning labeling machine encounters this problem, we should investigate the root cause.

　　Guangdong label‑applying machine manufacturer: It can be determined by the following methods.

　　I. Check the markings on the vacuum device.

　　Vacuum pumps have specific performance standards, particularly in labeling machines. These standards emphasize not only the suction force but also the timing difference generated by the pump. If the label is peeled off before the vacuum pump has completed its cycle—meaning the pumping duration is too late—the label cannot be properly adhered and will fall off. Conversely, if the pumping duration is too early, it can cause the label to wrinkle or distort. Therefore, we must carefully adjust this timing parameter of the vacuum pump.

　　II. Inspect the auxiliary air equipment, including the blow‑in inspection rod and the blow‑out air ports.

　　1. The timing difference in the auxiliary gas blow‑in inspection must also be precise; if it is too early or too late, some cases of non‑adhesion to the substrate may occur.

　　2. If the auxiliary air blow is too strong or too weak, it can cause the label to jam or fall off.

　　3. Use compressed air to check for debris inside the inspection rod; if foreign matter is expelled through the air‑blowing port, it indicates the presence of prefabricated components—address this promptly. Additionally, adhesive may occasionally accumulate in these areas during routine labeling, so regular maintenance is essential.

　　III. Query the height of the identification plate and the marking board

　　The relative height between the two must achieve an appropriate viewing angle, which is not necessarily uniform. When the label is adjusted too far away, it becomes detached and cannot be properly perceived or absorbed, leading to a loss of information; conversely, if the label is positioned too low, it can also result in misalignment or visual confusion. Each individual must make appropriate adjustments to strike the right balance.

　　In most cases, label applicators exhibit suction but fail to pick up the label base—this is typically due to issues with the vacuum system.

　　That concludes the methods for determining whether a labeling machine has suction. When various issues arise, it is advisable to contact more specialized after-sales technicians for assistance and adjustment, to avoid creating additional problems. After all, such adjustments should be carried out with greater precision and without error.

　　Guangdong Labeling Machine Manufacturer: Key Operational Considerations for Fully Automatic Labeling Machines

　　When we operate a new machine for the first time, it’s important to familiarize ourselves with its applications and the precautions that need to be observed. The same holds true for fully automatic labelers—so what are the key considerations when operating one?

　　1. Before commencing actual operation, be sure to verify the conveyor belt’s travel direction and feed direction on the fully automatic labeling machine.

　　II. Ensure that the label‑application direction matches the operating orientation.

　　3. Ensure that the height of the machine and equipment transport surface is appropriate.

　　4. Ensure that the identification roll is wound in the correct orientation.

　　5. Verify that the production line and the placement orientation on the automatic labeling machine are consistent.
