Common problems of automatic single labeling machine and their solutions

1 Label breakage: the breakage of the backing paper is also related to the quality of the backing paper, the scratch of the backing paper during the traction of the label and the adhesion of the label (1) check whether the backing paper has cut marks, whether the backing paper has dotted lines, etc., if any Need to change the label, can remind the manufacturer to avoid this situation when making the label - to avoid the occurrence of cuts and dashes, the common backing paper is generally grazin backing paper (2) if there is adhesion on the label, it is easy to pull it off Control the length of the label to ensure that it does not adhere to the labeled product (3) check whether there is scratch in the detour of the difference label 2 Labeling deviation is more than 2mm: label deviation and label deviation, label direction is not parallel to product conveying direction, product positioning detection is not accurate, label is not attached to the product along the labeling roller, product error is related to several factors, check the above factors, and then solve them pertinently A the label deviates, loosen the traction mechanism, pull the label back and forth to make it automatically go straight After the label is aligned, clamp the limit rings on both sides and guide the label B the direction of the marking belt is not parallel to the product conveying direction, which can be realized by adjusting the inclination of the labeling head D product error In the process of product manufacturing, edge error will cause labeling deviation, which can only be solved by controlling product quality 3 Continuous marking out: the continuous marking out and incomplete marking out are related to the sensitivity of electric eye detection, and the sensitivity can only be adjusted For the adjustment method, please refer to the previous chapter of electric eye adjustment A if the adjustment of the electric eye cannot be solved, it may be that the label is beyond the scope of application of the selected electric eye, or the electric eye is damaged Consult the manufacturer Another reason for B is that the tag is taken away The tag is not detected in the electric eye The electric eye is adjusted before and after the test position 4 The paper at the bottom of the stripping board is loose A The paper at the bottom is loose and the traction speed is too low, which is related to the slipping of the traction mechanism If the traction speed is too low, it can be solved by increasing the traction speed; B if the traction mechanism is slipping, tighten the locking screw of the traction roller until the paper does not slip C In addition, pay attention to whether the drive belt behind the receiving shaft is broken Key words: labeling machine, self-adhesive labeling machine, labeling machine manufacturer, Shanghai labeling machine, automatic labeling machine, double-sided labeling machine
