Description

Corrugated Cardboard Forming Machine {apparatus for forming corrugated paperboard}

The present invention relates to a corrugated cardboard forming apparatus, and in particular, a cartridge that increases productivity, reduces production costs, and significantly reduces the installation space by making it possible to produce various different kinds of corrugated cardboard using one corrugated cardboard forming apparatus. It relates to a corrugated paperboard (apparatus for forming corrugated paperboard) of the exchange method.

Typically, corrugated cardboard used to make paper boxes and the like for packaging various articles is molded by a corrugated cardboard molding apparatus. The corrugated sheet formed by the corrugating apparatus is, for example, single-sided corrugated cardboard, single-sided double-corrugated cardboard, single-sided multi-corrugated cardboard, double-sided single-corrugated cardboard, double-sided double-corrugated cardboard, double-sided multi-corrugated cardboard, double-sided single-sided corrugated cardboard. -There are various forms such as corrugated cardboard, Fuyang double-corrugated cardboard, Fuyang multi-corrugated cardboard, and the like.

One of the most basic processes for producing such various types of corrugated cardboard is to form a bone on the corrugated paper, for example, by stacking a single liner on one side of the corrugated corrugated paper. A double-sided single-core corrugated cardboard is obtained by laminating two liners with the interliner interposed therebetween, and a single-sided double-corrugated corrugated cardboard obtained by additionally laminating one corrugated core on the side of the corrugated side of the single-sided corrugated cardboard.

Corrugated sheet forming apparatus for forming the various types of corrugated cardboard as described above comprises a pair of bone forming rollers, a pair of bone forming rollers have a predetermined contour corresponding to the shape of the corrugated core while being engaged with each other.

The corrugator base passes between the pair of oscillating rollers that interlock with each other to form a bone on the corrugator base, and the corrugated core is moved in the state of being adsorbed to the outer surface of one oscillator of the pair of osmolal rollers The adhesive is then applied to the roller for contacting the adhesive.

Press rolls are disposed on top of the pair of bone forming rollers, and the press rolls are provided with a liner or cardboard (eg, single-sided corrugated cardboard) supplied to form a corrugated cardboard having a predetermined shape toward the corrugated corrugated core. By pressing, the corrugation can be effectively laminated to the liner or cardboard.

The adsorption of the corrugated medium to the one bone forming roller is made due to the fact that a plurality of grooves extending in the axial and circumferential directions are formed in one bone forming roller, and the high pressure suction force acts through these grooves. do. This suction force does not work from the moment the corrugated cardboard is laminated to the liner or corrugated cardboard, so that the completed cardboard can be easily transported to the outside or to the next molding step.

Corrugated paper base fed between a pair of bone forming rollers, and the liner or corrugated paper fed toward the corrugated corrugated medium are heated to a suitable temperature to ensure ease and accuracy of the molding by passing through heating rollers. Heat is also supplied to the center portion of the bone forming roller for ease and accuracy of molding.

However, in the corrugated sheet forming apparatus according to the prior art structured as described above, it takes considerable time and manpower to replace the bone forming roller, and thus productivity is lowered, thereby producing corrugated cardboard having various bone contours. In order to inevitably have to install a number of corrugated cardboard forming apparatus there was a problem that the production cost is increased and the installation space increases.

The present invention is proposed to solve the problems inherent in the corrugated sheet forming apparatus according to the prior art as described above, by installing the bone forming roller to replace the cartridge method by using a different corrugated cardboard forming apparatus of various It is possible to produce each of the corrugated cardboard, the main purpose is to increase the productivity, to reduce the production cost and to significantly reduce the installation space of the device.
