Labeling problem of self-adhesive automatic labeling machine and handling of abnormal conditions

At present, packaging technology is changing with each passing day, and the speed of replacement of related packaging equipment is also increasing. Among them, the self-adhesive automatic labeling machine adopts the self-adhesive roll labeling paper, and in the process of automatically feeding the bottle by the bottle unscrambler, the roll label paper is continuously torn off, and the bottle is attached to the bottle according to the required position. Automated packaging machinery.

  Two factors affecting the quality of labeling

 In the practical application of the self-adhesive automatic labeling machine, since the labeling process belongs to the end of the packaging process of the product, the quality of the labeling is directly related to the appearance image and marketing of the product, the labeling accuracy is high, the printing effect is good, and the label It is not a wrinkle, no bubble is the symbol of the product, otherwise it will invisibly reduce the product grade.

 According to the industry, the equipment has only reasonable mechanical structure design, various lines are arranged regularly, the components are structurally stable, and mechanical quality is superior, so that the machine can operate normally under long-term high load conditions. Speed and stability are the key factors affecting the quality of labeling.

 Among them, in terms of stability, only the stability is guaranteed, so that the equipment can run stably for a long time, the user's maintenance cost can be reduced, the user's reasonable production requirements can be met, the quality guarantee for the manufacturer, and the production leap.

 In terms of speed, the manufacturer should decide the speed of purchasing the self-adhesive automatic labeling machine according to their own requirements and the front-end production line. Comprehensive consideration can be matched to achieve true matching, rationalization and unification.

 Common exception handling in operation

 Missing or not labeling. When this situation is found, there are generally two reasons: one is that the photoelectric head is far away from the bottle body, and the photoelectric head can be adjusted in parallel with the labeling plate; the second is that the photoelectric head has low sensitivity and the potentiometer knob can be adjusted.

 Continuous bidding. There are two reasons for the continuous labeling of the self-adhesive automatic labeling machine: one is that the sensitivity of the photoelectric head is high, and the potentiometer knob is adjusted ; the second is that the transparency of the groove type photoelectric head is insufficient, that is, the sensitivity is not enough, and the distance is adjusted.

 The label is discounted. Many users have reported that the self-adhesive automatic labeling machine has a label discount in the labeling process. According to the industry, this phenomenon is generally caused by the labeling roller being too high, and the user can adjust the standard roller shutter or adjust the label roller holder lifting wheel.

 There are three reasons for this. First, the conveying speed is too fast, which can reduce the conveying speed; secondly, the speed of labeling and labeling is improper, and the labeling speed is adjusted; thirdly, the pressure spring of the pressure labeling shaft is too tight, and the pressure spring of the pressure labeling shaft is adjusted.

 Typing is unstable. Self-adhesive automatic labeling machine If the three speeds of conveying, feeding and labeling are too fast, the coding machine can not respond to the situation, and the three speeds can be adjusted.
