1.紙板橫向上翹的主要原因是水分不均勻，紙板向水分高的一側(cè)彎曲，即紙張水分高。那么如何減少紙張中的水分呢？

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?

一種方法是減少單面機(jī)的上糊量，同時(shí)在糊機(jī)處增加上糊量。因?yàn)閮烧呤窍嗷?duì)應(yīng)的，所以在這里增加，在那里減少。

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.

另外一種方法是增加面紙的水分，在面紙上噴水增加濕度，減少預(yù)熱缸上紙板的包角，也可以增加面紙的水分。

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.

還有一種方法是降低熱板的溫度，這樣下面紙板的水就不容易向上轉(zhuǎn)移，同時(shí)可以提高速度，解決紙板橫向上翹的問題。對(duì)于內(nèi)紙有兩種措施。一種方法是減少立交橋的積紙量，從而降低內(nèi)紙水分在上面蒸發(fā)的概率；二是改變內(nèi)紙的預(yù)熱。當(dāng)預(yù)熱缸的包角變大時(shí)，上面紙板的水分會(huì)減少。其實(shí)這是控制水分的原理。

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.橫向下翹和橫向下翹的原理與橫向上翹相反，因?yàn)槊婕埖乃诌^高，可以增加里紙的水分，增加單面機(jī)的膠水量，或者增加立交橋的積紙量，因?yàn)榱⒔粯虻姆e紙量增加了水分，不容易散發(fā)。此外，我們可以減少底紙（里紙）的預(yù)熱，增加底紙的水分，在底紙上噴水。我們還可以降低瓦線的速度，即增加熱板的速度，這與橫向上翹相反。

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.橫向下翹和橫向下翹的原理與橫向上翹相反，因?yàn)槊婕埖乃痔撸梢栽黾永锛埖乃郑黾訂蚊鏅C(jī)的膠水量，或者增加天橋的積紙量，因?yàn)樵黾犹鞓虻姆e紙量不容易散發(fā)水分。此外，我們可以減少底紙(內(nèi)紙)的預(yù)熱，增加底紙的水分，在底紙上噴水。我們還可以降低瓦線的速度，即增加熱板的速度，這與橫向上翹相反。

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.縱向彎曲和翹曲的縱向彎曲主要是由拉力引起的。我們主要調(diào)整預(yù)熱缸的角度和原紙架的剎車。如果剎車向下拉意味著面紙的拉力太大，面紙的拉力太大，那么包角會(huì)變小，剎車會(huì)放松。如果向上彎曲，意味著內(nèi)紙的拉力很大，即增加三重預(yù)熱缸的包角和下面大皮帶的角度，從而提高內(nèi)紙的拉力。

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.設(shè)備控制設(shè)備應(yīng)有一定的自動(dòng)控制方法，如瓦楞輥、壓力輥、糊輥的平行度和壓力，否則在加載困難的情況下，您的調(diào)整將毫無意義。預(yù)熱缸和溫度應(yīng)保持均勻。只有當(dāng)溫度均勻時(shí)，包角的大和小才能發(fā)生變化。在這個(gè)過程中，應(yīng)該有一個(gè)噴水裝置。眾所周知，熱板的位置、面紙的位置和立交橋的積紙量都是通過自動(dòng)控制來實(shí)現(xiàn)的，因此有必要掌握控制值。當(dāng)然，我們應(yīng)該注意傳送帶的透氣性。通常，透氣性越好，誤差越低。總之，上述幾點(diǎn)應(yīng)具有相應(yīng)的控制值和范圍。

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.
