Common causes of failure of semi-automatic flat labeling machine

According to the feedback from Chunlei Intelligent employees during the debugging of the machine, some common problems may occur during the use of the semi-automatic flat labeling machine, which will affect the user's machine experience and work efficiency. The following are some common problems summarized by Chunlei Intelligent's editor and their solutions:

1. Broken bottom line: The label ground paper breaks during labeling, which may be caused by the quality of the bottom paper, traction scratches, and label adhesion. The solution includes checking whether the bottom paper is damaged, requiring the label supplier to control the die-cutting depth to avoid cutting the bottom paper, and using suitable bottom paper; checking whether the label of the labeling machine is scratched during the process of moving, and if so, adjusting the mechanism; checking whether the label is adhered to the labeled product during labeling, and if necessary, controlling the labeling machine's label length.

2. Label running deviation: The labeling accuracy deteriorates and exceeds the requirements. The label belt direction may be not parallel to the product conveying direction due to the deviation of the label belt, the direction of the label belt, and the limit rings on both sides of the clamp. The solution is to adjust the inclination of the labeling head of the labeling machine to achieve parallelism; the slip of the traction wheel may be related to the wear of the traction wheel and the loosening of the traction wheel locking screw. The traction wheel locking screw can be tightened.

3. Continuous labeling: two or more labels appear continuously. It may be due to the disorder of the detection sensitivity of the labeling machine's electric eye. The solution includes adjusting the sensitivity of the electric eye. If the sensitivity adjustment is not enough, you may need to replace the electric eye with the labeling machine manufacturer; check whether the label belt of the labeling machine is deviated, and adjust the electric eye to the detection position front and back.

4. The bottom line of the stripping plate is loose: the ground paper is not open enough when the label is peeled off. It may be due to the insufficient normal traction of the labeling machine. The solution includes checking whether the traction speed is too low, if so, increase the traction speed; check whether the traction mechanism is slipping, if so, tighten the locking screw of the traction roller; check whether the transmission belt behind the receiving shaft is broken, if the belt is broken, it needs to be replaced immediately.

5. Conveyor belt problem: The conveyor belt may be worn, damaged or rusted due to long-term overload or humid environment, resulting in jamming or shutdown during conveying and labeling. The solution is to perform regular maintenance and perform mechanical work according to the specified parameters.

6. Damage to the labeling rotating shaft: Due to the overload of the flat labeling machine, the temperature inside the shaft increases, the friction coefficient increases, and problems such as missing labels, no labels, and repeated labels may occur. The solution is to regularly add lubricating oil to the inside and outside of the shaft and parts.

7. Problems caused by software: When using the flat labeling machine to adjust parameters, the system may be unstable, and the incorrect operation of the operator may cause the system to be garbled and the wrong command characters and fail to work. The solution is to choose good quality, high performance, and stable labeling machine equipment, and operate it correctly.

The above are some common problems and solutions of semi-automatic flat labeling machines summarized by Chunlei Xiaobian. Daily attention can ensure that the machine parts are not damaged, ensure the normal use of the machine, and ensure the operation and work efficiency of the machine. In addition, when operating the machine, put the product and take your hands away in time to avoid pinching and damaging the machine.
