Description

[0001] CORRUGATED CARBON BOARD MANUFACTURING MACHINE [0002]

The present invention relates to a new structure of quadruple corrugated cardboard having a high strength and a new structure for manufacturing such quadruple corrugated cardboard.

Generally, a corrugated cardboard widely used for wrapping paper or the like is constituted by attaching a planar line paper to both sides of corrugated paper folded in a corrugated form, and in recent years, a double corrugated cardboard in which the corrugated paper is disposed in double is widely used.

1, the double corrugated cardboard is constituted by alternately laminating two corrugated papers 1 and three line papers 2, and the corrugated paper 1 and the line paper 2 are bonded to each other with adhesive .

As shown in FIG. 2, the corrugated cardboard manufacturing apparatus for manufacturing the double corrugated cardboard according to the present invention is such that the first to fifth rolls 3a wound around the circumference of the corrugated cardboard 3b are vertically spaced apart from each other A molding machine 4 for pressing the raw paper roll 3b released from the paper rolls 3a and 4b of the uncoiler 3 to form a wave form, The raw paper 3b unrolled from the paper rolls 3a, 3b and 5b and the raw paper 3b having a plurality of balls formed at a predetermined interval while passing through the molding machine 4 are coated with an adhesive, And a cutter 6 for cutting the corrugated cardboard produced through the punching machine 5 to a predetermined size.

The forming machine 4 is generally called a spinning machine and presses the circumferential surface of the raw paper 3b by using a roller having a valley on the circumferential surface so that the raw paper 3b is rotated at right angles to the extending direction of the raw paper 3b, As shown in Fig.

Recently, as the demand for corrugated cardboard gradually increasing in intensity has been increased, a method for manufacturing a quadruple corrugated cardboard having alternately stacked four corrugated cardboard (1) and five line cards (2) has been studied, In order to manufacture the quadrangular corrugated paper having the above-described structure, nine paper rolls 3a are provided in the uncoiler 3 from 1 to 9, nine paper rolls 3a are formed by using four molding machines 4, The raw paper 3b unrolled from the paper rolls 3a, 6b and 8 of the paper rolls 3a, 3b, 5c, 7d, (3b), which is loosened from the base paper (3b).

Therefore, not only the apparatus becomes excessively complicated, but also the difficulty of manufacturing corrugated cardboard increases, while the strength of the finished corrugated cardboard is not improved as desired.

Particularly, when a box is manufactured by using the manufactured four corrugated cardboard, the strength to withstand the vertical load increases, but the strength to withstand the lateral load is lower than the increase in the strength withstanding the vertical load .

Therefore, there is a need for a new method to solve such a problem.

At this time, the molding machines 42 and 52 are formed in the raw paper sheets 41b and 51b with a trough extending in a direction perpendicular to the extending direction of the raw paper sheets 41b and 51b.

The structure of the first and second corrugated cardboard manufacturing units 40 and 50 is the same as that of the conventional corrugated cardboard manufacturing apparatus, and a detailed description thereof will be omitted.

The second corrugated cardboard manufacturing unit 50 is disposed at right angles to the first corrugated cardboard manufacturing unit 40.

That is, the first corrugated cardboard manufacturing unit 40 is arranged such that the uncoiler 41, the forming machine 42, the jamming machine 43 and the cutter 44 are spaced apart from each other in the front-rear direction of the jamming means 60 , And the raw paper 41b is fed from the front to the rear.

Therefore, the corrugated cardboard 11 of the lower double corrugated cardboard 10 manufactured by the first corrugated cardboard manufacturing unit 40 is formed with the laterally extending corrugations.

The second corrugated cardboard manufacturing unit 50 is arranged such that the uncoiler 51 and the molding machine 52 and the jamming machine 53 and the cutter 54 are spaced apart from each other on the right side of the jumping means 60 So that the raw paper 51b is supplied laterally.

Therefore, the corrugated cardboard 31 of the upper double corrugated cardboard 30 manufactured by the second corrugated cardboard manufacturing unit 50 is formed with the corrugations extending in the forward and backward direction.
