Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic papermaking machine for Japanese paper, which is capable of filtering Japanese paper fibers (particularly long fibers) in the same manner as in manual work.

[0002]

2. Description of the Related Art The currently used paper is produced by a device that has been developed in various ways in accordance with the development of science and technology. It is formed in a completely unchanged state. Therefore, at present, there are two types of paper manufacturing, one that is developed by hand and one that is easily automated.

[0003]

[Problems to be Solved by the Invention] However, since the former is a manual work, the same work must be repeated by heavy labor, resulting in severe fatigue, and the work requires a lot of intuition and requires a unique technique. , It takes a long time to learn the technique.

The latter is the mechanization of a so-called "reservoir method" in which a paper material is supplied onto a cage and water drops due to natural or slight vibration to form a paper layer. For this reason, since there is no action of “lotion” to discard the remaining stock, binding fibers and impurities in the stock go into the paper layer, and a uniform and beautiful paper cannot be obtained. Since there is no wobbling or horizontal wobbling motion, it is difficult to obtain the original characteristics of Japanese paper, such as the fact that the fibers stretch in the vertical and horizontal directions and are strong even if they are thin. For this reason, there were many problems in making paper with long fibers, such as Japanese paper, such as Japanese pepper and Sanpei, and it was very inconvenient in the production of Japanese paper.

[0005]

The present invention eliminates such inconvenience, and moves the squeezing frame in the same manner as when a person manually strains washi to manufacture washi with long fibers. The purpose is to provide an automatic papermaking machine for Japanese paper.

That is, a frame-shaped rocking base is suspended from the upper part of the gate-shaped frame main body by a connecting rod, and the piston rod of the third scale cylinder for fixing the head to the frame main body is connected to the rocking base to make it horizontal.
