1.纸板横向上翘的主要原因是水分不均匀，纸板向水分高的一侧弯曲，即纸张水分高。那么如何减少纸张中的水分呢？
1. The main reason for the lateral upturning of the paperboard is the uneven moisture. The paperboard bends to the side with high moisture, that is, the paper has high moisture. So how to reduce the moisture in the paper?
一种方法是减少单面机的上糊量，同时在糊机处增加上糊量。因为两者是相互对应的，所以在这里增加，在那里减少。
One method is to reduce the amount of paste on the single-sided machine and increase the amount of paste on the paste machine at the same time. Because the two correspond to each other, they increase here and decrease there.
另外一种方法是增加面纸的水分，在面纸上喷水增加湿度，减少预热缸上纸板的包角，也可以增加面纸的水分。
Another method is to increase the moisture of the face paper, spray water on the face paper to increase the humidity, reduce the wrapping angle of the paperboard on the preheating cylinder, and also increase the moisture of the face paper.
还有一种方法是降低热板的温度，这样下面纸板的水就不容易向上转移，同时可以提高速度，解决纸板横向上翘的问题。对于内纸有两种措施。一种方法是减少立交桥的积纸量，从而降低内纸水分在上面蒸发的概率；二是改变内纸的预热。当预热缸的包角变大时，上面纸板的水分会减少。其实这是控制水分的原理。
Another method is to reduce the temperature of the hot plate, so that the water of the paperboard below is not easy to transfer upward. At the same time, it can improve the speed and solve the problem of transverse upturning of the paperboard. There are two measures for inner paper. One method is to reduce the paper volume of the overpass, so as to reduce the probability of water evaporation on the inner paper; Second, change the preheating of inner paper. When the wrapping angle of the preheating cylinder becomes larger, the moisture of the upper paperboard will be reduced. In fact, this is the principle of controlling moisture.
2.横向下翘和横向下翘的原理与横向上翘相反，因为面纸的水分过高，可以增加里纸的水分，增加单面机的胶水量，或者增加立交桥的积纸量，因为立交桥的积纸量增加了水分，不容易散发。此外，我们可以减少底纸（里纸）的预热，增加底纸的水分，在底纸上喷水。我们还可以降低瓦线的速度，即增加热板的速度，这与横向上翘相反。
2. The principle of horizontal down warping and horizontal down warping is opposite to that of horizontal up warping. Because the moisture of the face paper is too high, it can increase the moisture of the inner paper, increase the glue amount of the single-sided machine, or increase the paper accumulation of the overpass, because the paper accumulation of the overpass increases the moisture and is not easy to distribute. In addition, we can reduce the preheating of the backing paper (lining paper), increase the moisture of the backing paper and spray water on the backing paper. We can also reduce the speed of the tile line, that is, increase the speed of the hot plate, which is opposite to the lateral upturning.
3.横向下翘和横向下翘的原理与横向上翘相反，因为面纸的水分太高，可以增加里纸的水分，增加单面机的胶水量，或者增加天桥的积纸量，因为增加天桥的积纸量不容易散发水分。此外，我们可以减少底纸(内纸)的预热，增加底纸的水分，在底纸上喷水。我们还可以降低瓦线的速度，即增加热板的速度，这与横向上翘相反。
3. The principle of horizontal down warping and horizontal down warping is opposite to that of horizontal up warping, because the moisture of the face paper is too high, it can increase the moisture of the inner paper, increase the glue amount of the single-sided machine, or increase the paper volume of the overpass, because it is not easy to emit moisture by increasing the paper volume of the overpass. In addition, we can reduce the preheating of the backing paper (inner paper), increase the moisture of the backing paper and spray water on the backing paper. We can also reduce the speed of the tile line, that is, increase the speed of the hot plate, which is opposite to the lateral upturning.
4.纵向弯曲和翘曲的纵向弯曲主要是由拉力引起的。我们主要调整预热缸的角度和原纸架的刹车。如果刹车向下拉意味着面纸的拉力太大，面纸的拉力太大，那么包角会变小，刹车会放松。如果向上弯曲，意味着内纸的拉力很大，即增加三重预热缸的包角和下面大皮带的角度，从而提高内纸的拉力。
4. Longitudinal bending and warping longitudinal bending is mainly caused by tension. We mainly adjust the angle of preheating cylinder and the brake of base paper holder. If the downward pull of the brake means that the tension of the tissue paper is too large and the tension of the tissue paper is too large, the wrapping angle will become smaller and the brake will be relaxed. If it bends upward, it means that the tension of the inner paper is large, that is, increase the angle of the triple preheating cylinder and the angle of the lower large belt, so as to improve the tension of the inner paper.
5.设备控制设备应有一定的自动控制方法，如瓦楞辊、压力辊、糊辊的平行度和压力，否则在加载困难的情况下，您的调整将毫无意义。预热缸和温度应保持均匀。只有当温度均匀时，包角的大和小才能发生变化。在这个过程中，应该有一个喷水装置。众所周知，热板的位置、面纸的位置和立交桥的积纸量都是通过自动控制来实现的，因此有必要掌握控制值。当然，我们应该注意传送带的透气性。通常，透气性越好，误差越低。总之，上述几点应具有相应的控制值和范围。
5. The equipment control equipment shall have certain automatic control methods, such as the parallelism and pressure of corrugated roll, pressure roll and paste roll, otherwise your adjustment will be meaningless in the case of difficult loading. The preheating cylinder and temperature shall be kept uniform. Only when the temperature is uniform can the wrap angle change. In this process, there should be a sprinkler. As we all know, the position of hot plate, the position of face paper and the paper volume of overpass are realized through automatic control, so it is necessary to master the control value. Of course, we should pay attention to the air permeability of the conveyor belt. Generally, the better the air permeability, the lower the error. In short, the above points should have corresponding control values and ranges.
