First, the bottom paper is broken
1. Check whether the backing paper is cut or not. If the backing paper is cut, it is necessary to replace the backing paper with high quality. Jian recommends the use of glassine backing paper, and requires the label supplier to control the depth of die cutting so as not to damage the backing paper.
2. Check whether there are scratches in the label detour, and eliminate the scratch factors.
3. If the label sticks, the label is easy to tear. Control the length of the next label to ensure that it does not stick to the labelled product.
Second, the labeling deviation exceeds the accuracy requirements
1. If the label is off-track, loosen the traction mechanism, and pull the label back and forth to make it go straight automatically. After the label is aligned, clamp the limit rings on both sides to guide the label.
2. The direction of the labeling tape is not parallel to the conveying direction of the product, which can be achieved by adjusting the inclination of the labeling head.
3. The traction wheel is slipping, the traction wheel is worn, and the traction wheel locking screw is loose. Both reasons can be tightened. The traction wheel locking screw can be tightened.
4. Product error. In the process of product production, edge error will cause labeling deviation, which can only be solved by controlling product quality.
What's more ,Continuous bidding
1. If the adjustment of the electric eye still cannot be solved, it may be that the label exceeds the applicable scope of the electric eye selected, or the electric eye is damaged, and you need to consult the manufacturer.
2. Another reason is that the label is off-track, and the electric eye does not detect the label, so adjust the electric eye back and forth to the detection position.
Lastly ,the bottom paper is loose at the peeling board
1. The slack of the bottom paper and the low traction speed are related to the slippage of the traction mechanism. If the traction speed is too low, it can be solved by increasing the traction speed;
2. If the traction mechanism slips, tighten the locking screw of the traction roller until the bottom paper does not slip.
3. In addition, pay attention to whether the transmission belt behind the receiving shaft is broken.
