Description

Paper Machine {KOREAN PAPER FORMING DEVICE}

The present invention relates to a papermaking apparatus used in the manufacture of hanji, and more particularly, to a papermaking apparatus that can eliminate the difference in strength in the horizontal and vertical directions of the manufactured Hanji.

Hanji is still being used for calligraphy, crafts or special purposes even though the area of use is being shrunk by papers produced on a large scale in paper mills.

In particular, in recent years, the usefulness in special fields such as filter paper, donji stripe has been recognized, on the other hand, the limitations due to the characteristics that come from the manufacturing process of Hanji has also been highlighted.

In other words, the general Hanji, as shown in the Republic of Korea Patent No. 0185366, installed a guide (rail) in the paper-making solution bath in which the paper was processed and squeezed in water, and then filtered the papermaking solution with the foot while the foot rest (foot) was placed on it. It is prepared by the method of drying the paper by reciprocating -3 times and drying it.

The Korean paper made in this way is 1.5-2 times stronger than the machine direction (MD) strength (measured when the force is applied in the horizontal direction) to the lateral strength (CD, strength measured when the force is applied in the vertical direction). As a result, the strength of the remarkable difference depends on the cutting direction of the Korean paper.

Such a difference in strength along the direction becomes very unfavorable conditions for special applications such as money strips used to bundle money and filter papers for filtering powder after pore such as gold and silver. There was a problem in that careful attention is required, such as the direction of force should be displayed using a special mark.

The present invention solves the problems of the conventional Korean paper by presenting a paper making device that can produce a paper that has a similar difference in strength in the longitudinal direction as well as in the horizontal direction, and devised for the purpose of manufacturing a high quality, high strength paper. It is.

To this end, the present invention is a foot box 10 for fixing the foot 20, the paper box 30 is installed so that the outlet 31 is located at a position higher than the foot on the front of the foot, and the paper box and the bottom of the foot It is composed of a paper box (40) for receiving papermaking filtrate, a pumping device (50) for supplying the papermaking paper from the papermaking box to the paper box, and an opening and closing device (60) for electrically controlling the outlet of the paper box; , The footrest proposes a papermaking device having a structure coupled to the ceiling using a hanger 70 to maintain the level in the medallion state.

Figure 1 shows the configuration of the present invention, Figure 2 shows an embodiment of the foot according to the present invention by which the present invention will be described in detail as follows.

Foot 10 is a device for fixing the foot and the lower frame 11 and the upper frame 12 is coupled by the rear fold opening 13, the structure is maintained by the front fastener (14) Has

The upper and lower frames are formed in a lattice form, and the vertical members 15 are coupled at regular intervals to prevent deformation of the frame, and handles 16 are formed on both sides of the upper frame in a protruding form.

Opening the upper frame, the foot 20 is placed in the middle, and then close the upper frame again, close the fasteners in the state so that the upper and lower frames do not open, the paper box from the paper box 30 to filter and float operation It is a device that performs a series of paper molding process for discarding the filtrate in the paper box after the carry out, the foot is removed.

The present invention forms a hook (71) in the middle portion of the handle protruding longitudinally in both longitudinal and longitudinal directions of the foot, and the hanger 70 is coupled to the hook to the top of the device by the structure It consists of a structure installed with a foot so that the grass paper forming and floating on the foot, and the paper forming operation of discarding the filtrate is carried out by manpower. It has a feature that the fiber can be formed in both the transverse direction and the longitudinal direction.

The paper box 30 is a rectangular container having a size slightly larger than the width of the foot, and has an outlet 31 formed on the side of the foot, and the outlet has a structure that can be mechanically opened by the opening and closing device 60.

Switching device is configured in a variety of ways to discharge the appropriate amount of grass paper by the switch operation, such as a structure to open the shutter of the outlet to operate the solenoid by pressing the foot switch 61.

In the paper box, the pumping device 50 interlocked with the water level sensor 51 is installed so that the appropriate amount of paper is always in the standby state. When the water level of the paper is lowered by use, the pumping device is operated to make the paper in the paper box. It will be fed into the box.

The paper box 40 is a rectangular water tank to accommodate the filtrate generated during the molding operation of the paper, and is installed in the paper box and the bottom of the foot as an element installed to supply the filtrate to the paper box.

In the present invention by the above configuration, the fixing of the foot, the supply of paper from the paper box, the paper forming operation, the discharge of the foot is made by the intention of the operator, the supply of paper to the paper box is automatically made.

The forming operation of the papermaking is not limited to the movement in the limited direction on the rails installed in the front and rear directions, and the movement of the papermaking is also performed in the horizontal direction so that the fiber tissue of the papermaking is formed into a horizontal and vertical stack. In Korean paper, not only the strength in the longitudinal direction but also the strength in the transverse direction is greatly improved.

3 is a representation of the movement direction of the foot and the arrangement structure of the fiber structure, when performing the operation of the front and rear direction (MD) twice, and the operation of the left and right (CD) twice when forming the papermaking In the lower layer, the fibers are formed in the yy direction, and in the upper layer, the fibers are formed in the xx direction so that each fiber is entangled in a lattice form, thereby having uniform strength regardless of the direction.

The following table shows the Korean paper (a) obtained after applying the horizontal and vertical motions using the apparatus according to the present invention when using the same papermaking solution, and the Korean paper manufactured when only the vertical motion was applied as before. The comparison result of b) is shown.

Test Item / Sample a b Basis weight (g / ㎡) 50 50 Tear strength (gf). Vertical 88 side 68 86 vertical 43 Tensile strength (kgf) 8.7 horizontal 6.7 Vertical 8.4 horizontal 4.1 Number of festivals (times) Vertical 3000 horizontal 2300 Vertical 2900 horizontal 1700

The results are the results of the test by the method of the self-made samples by the KSM7013-95 (base weight test), KSM7016-95 (tear test), KSM7014-95 (tensile test), KSM7065-97 (fatigue test). In addition, the overall performance is improved for b), and in the case of horizontal performance, the result is approximately twice or more.

The present invention can impart transverse and longitudinal motions during papermaking to significantly improve the strength of the finished hanji, and in particular, by improving the transverse strength, it is possible to produce high quality, high strength hanji.
