Description

Corrugated Cardboard Forming Machine {apparatus for forming corrugated paperboard}

The present invention relates to a corrugated sheet forming apparatus, and in particular, it is possible to produce a variety of different types of corrugated cardboard using one corrugated sheet forming apparatus, thereby increasing productivity, reducing production costs and significantly reducing the installation space of the apparatus. By using the air cushion method that blows compressed air from the outside toward the bone forming roller and compresses the bone core formed with the bone against the outer surface of the bone forming roller, it prevents the loss of heat supplied to the center of the bone forming roller. Apparatus for forming effectively prevents the poor quality of the corrugated cardboard and basically eliminates the possibility of clogging, and also prevents the degradation of the high basis weight paper and the poor quality caused by the lack of adsorptive power. corrugated paperboard All.

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.

Further, in the prior art, since the air suction method of adsorbing the bone core formed with bone by using the suction force supplied to the adsorption hole formed in the bone molding roller to the bone molding roller is used, Loss of heat supplied to the center of the forming roller is caused, thereby degrading the formability of the core core.

In addition, when the surface of the bone forming roller is exposed to the outside due to the narrow width of the corrugated bone to be formed, or when there is a damaged part due to a hole or tear in a portion of the corrugated core, the adhesive is applied through the exposed and / or damaged areas. As the pool of the roller enters into the suction hole, pool clogging is caused.

Due to the pool clogging phenomenon, the adsorption force is lowered, a part of the core core is lifted or folded, and it becomes difficult to adsorb the high basis weight paper, thereby increasing the likelihood of poor quality of the final product.

The present invention was created to solve the problems inherent in the corrugated cardboard forming apparatus according to the prior art as described above, the object of the present invention is to be able to produce a variety of different types of corrugated cardboard using a single corrugated cardboard forming apparatus This increases productivity, lowers production costs, and significantly reduces the installation space for equipment.

The present invention also uses the air cushion method that blows compressed air from the outside toward the bone forming roller and compresses the bone core formed with the bone against the outer surface of the bone molding roller, thereby causing a loss of heat supplied to the center of the bone molding roller. There is another purpose to prevent the possibility of preventing, effectively preventing the poor quality of corrugated cardboard, and to fundamentally exclude the possibility of clogging phenomenon.

It is still another object of the present invention to provide a corrugated cardboard molding apparatus which does not cause a decrease in speed and quality defect of a high basis weight paper due to lack of adsorptive force.
