Several Causes Of Decoupling Of Drying Department Of Paper Plate Making Machine
- Oct 23, 2017 -

Into the dry part of the wet paper, dryness has reached more than 32%, with a certain strength. But there will be broken in the dry part of the phenomenon.

Paper Plate Making Machine causes the reasons for decapitation, there are several main aspects:

1) The strength of the paper itself is not enough or there is a weak point

The paper is too large moisture, dry cloth knuckle is not regular, easy to squeeze out the paper on the end of India, resulting in weak points leaving the paper break;

In the press section of the deduction, serious, that is, when the late tension in the dry when there is a large break, or in the wet part of the paper on the horizontal gap, and holes, etc., will also cause the drying section of the paper break;

When the amount of paper is fluctuating, the drying speed will be inconsistent, Paper Plate Making Machine the paper will be small and dry, so that it will dry easily and the paper will shrink too much and break at the dry end. When this happens, it should be addressed for specific reasons.

2) The tension of the sheet is too large to cause breakage

There are two reasons why paper tension is too large:

First, the drive between the groups of the dryer is too large, often in the late drying sheet more intense, resulting in broken head, or transmission parts have problems, such as belt slip, irregular gears, so that tension fluctuations, also Will cause a break. So pay attention to adjust the tension between the dryer, Paper Plate Making Machine always pay attention to the transmission of the work-like decorations is very important.

Second, the dryer temperature is too high, in the early drying of the cylinder will be caused by the serious damage caused by the broken head, and in the drying process, will cause the paper too dry, Paper Plate Making Machine so that the film shrinks sharply and decapitated. Sometimes even a long time to break, because of a long time to heat the paper to make the cylinder temperature rise, and then transfer paper running, it will happen this break.

Therefore, the dryer "see steam" to pay attention to the vapor pressure and dryer temperature changes.

3) debris between the dryer caused the paper break

When there is a broken head when the clean paper is not handled, with the paper through the dry cloth and dryer between the easy to break the paper sheet and break the head; scraper and leakage of paper, easy to stick on the edge of the paper , First to make paper edge damage, caused by the late break in the dry; paper from the damaged paper into some of the sticky material, will stick to the cylinder caused by the decapitation. Therefore, Paper Plate Making Machine after the break, pay attention to clean air with compressed air, while often pay attention to remove the blade of the paper foam, and pay attention to the working conditions of scraper.

4) dry cloth caused by the broken head

Dry cloth pleated, will make the corresponding sheet of paper, due to poor contact with the boring and poor drying, so that between the dryer and calendering machine between the broken; dry cloth joints rough, easy to crush the paper, Broken cloth; dry cloth sticky with oil and resin, will stick to the paper; even canvas side open line, rejection to rejection to go, will open the paper edge, resulting in full-width and so on. Therefore, in normal work, Paper Plate Making Machine should always pay attention to observe the work of dry cloth, found that the problem in a timely manner.
