Automatic double-side labeling machine is a production line equipment for labeling on the left and right sides. However, even the best-quality machines sometimes fail. Let's take a look at how to solve some common equipment failures.
1.Bottom paper break
The bottom paper break is closely related to the three factors of the quality of the label backing paper, the scratching of the backing paper in the label pulling path, and the label adhesion.
a. Check whether the backing paper is cut. If the backing paper is cut, you need to replace the high-quality backing paper. Jian recommends the use of glassine base paper, and requires the label supplier to control the depth of die cutting, can not hurt the base paper.
b. Check whether there are any scratches in the label detour, and eliminate the scratch factors.
c. 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 labeled product.
2. Labeling deviation exceeds 2mm
The label deviation is deviated from the label tape, the label tape direction is not parallel to the product conveyance direction, the traction wheel is slippery, the product positioning test is not accurate, and the label is not attached to the product along the labeling roller. There are several factors related to the product error. Check the above. These factors should be addressed in a targeted manner.
* The label is off, loosen the traction mechanism, pull the label back and forth, and let it go straight. After the label is straight, clamp the limit rings on both sides to guide the label.
* The direction of the tape is not parallel to the direction of product conveyance. It can be achieved by adjusting the inclination of the labeling head.
* The traction wheel is slippery, the traction wheel is worn, and the traction wheel lock screw is loose. There are two reasons to tighten the traction wheel lock screw.
* Product error. During the production process, the edge error will cause labeling deviation. Only by controlling the product quality can it be solved.
3. Continuous bidding
The continuous out-labeling and out-labeling are not completely related to the detection sensitivity of the electric eye. You can adjust the sensitivity. For the adjustment method, please refer to the previous chapter of the electric eye adjustment.
If the adjustment of the electric eye still cannot be solved, the label may exceed the applicable scope of the selected electric eye, or the electric eye is damaged, and you need to consult the manufacturer.
Another reason is that the label is off, and the electric eye does not detect the label. Just adjust the electric eye back and forth to the detection position.
4. The backing paper at the peeling plate is loose
The slack of the backing paper and the low traction speed are related to the slip of the traction mechanism. If the traction speed is too low, increasing the traction speed can be solved; if the traction mechanism is slipping, tighten the locking screw of the traction roller until the bottom paper does not slip . In addition, pay attention to whether the drive belt behind the take-up shaft is broken.
