Description

Rotary cutter device for corrugated box manufacture {Corrugated box manufacture rotary cutter device}

The present invention relates to a rotary cutter device that creates a bent portion along a fold line for easy folding and at the same time cutting a portion of the cardboard material in the process of manufacturing a packaging box using cardboard, more specifically manufacturing The present invention relates to an improved apparatus for easily changing the position of a cutting knife according to the size or shape of a cardboard box to be made, and to facilitate the firm installation and disassembly of the cutting knife.

Box corrugated paper, which is generally used as a material such as a packing box, is further provided with a zigzag reinforcing material for shock absorption and shearing surface reinforcement between the upper and lower grounds separated by the producer. Through the cutting process to cut the cardboard for box and print it is used as a box.

Conventionally, as a representative cutting device for cutting the cardboard for box as described above, there is a thomson type of model cutting machine, the blade is lowered and cut in a state where the supply of a single piece of cardboard seated in the correct position, and then again By repeating the feeding and sorting of the chapter, the processing speed and the specification of corrugated cardboard that can work has a limited disadvantage.

In order to solve the above-mentioned disadvantages, the use of a rotary cutter type cutter which forms cutting and pressing portions while corrugated cardboard passes under the rotating cylinder by forming a blade on the outer surface of the rotating cylinder has been increased. Discomfort is also found in. Although the position of the cutting knife, in particular, the distance between the two cutting knives, should be easily changed according to the size or shape of the box to be manufactured, according to the conventional configuration, there is no configuration that can move the blade quickly and easily in the longitudinal direction. If the standard is changed, there are inconveniences and wasteful problems, such as the use of a rotary cutter after making another blade as a whole.

In addition, according to the conventional configuration, it is very inconvenient to separate and combine the blades when replacement or repair is necessary due to the wear of the knife, and it is expensive to replace the blades because they are integrated in a separate block or pressure piece. There were also disadvantages.

The present invention is to solve the above problems, the rotary cutter device of the present invention is configured to be easily moved in the longitudinal direction only the blade for pressing the pressure blade for the fixed state to quickly cope with changes in the box specifications It is aimed to improve the efficiency of box manufacturing work using the rotary cutter device as a whole by improving the convenience of the cutting machine, and improving the convenience of the blade. .

The present invention for achieving the above object is fixed to the blade and the pressing blade using a block on the outer surface of the rotating drum, while the cutting knife is coupled to the top of the pressing piece in the curved portion of the cutting knife the same as the cross-sectional shape of the pressing piece It is formed so that the pressing piece is inserted into the coupling groove so that the cutting knife can be easily moved in the longitudinal direction of the pressing piece, and the inner side of the straight portion of the cutting knife is combined to form a close contact with the outer surface of the pressing piece cutting knife It is characterized in that it is configured to facilitate disassembly and assembly while effectively withstanding the strong force generated when the cutting action.

According to the present invention, since the position of the cutting knife is changed very quickly and conveniently according to the size or size of the cardboard box to be manufactured, the productivity according to the manufacture of the cardboard box can be greatly improved, It is very useful design such that effective maintenance is possible while reducing the manpower and cost according to the overall maintenance of the rotary cutter device because it is possible to maintain a long life due to the combination and to remove and combine the cutting knife very quickly and conveniently. Can be.

Hereinafter, a preferred embodiment of the present invention based on the accompanying drawings in detail.

The cutter device of the present invention is configured so that the box corrugated cardboard 1 passes between the supporting drum 10 'and the cutting drum 10, and on the outer surface of the cutting drum 10, two mounting blocks 20 are formed. The installation block 20 is installed on the cutting drum 10 by fastening means 21 fastened toward the center of the cutting drum 10, and some of the mounting blocks 20 are circumferential in the cutting drum 10. It is installed to be able to move to.

An installation groove 22 is provided at the center of the installation block 20, and a pressure piece 30 having a locking protrusion 31 at the lower end and a pressure blade 32 at the upper end thereof is provided inside the installation groove 22. It is inserted and fixed in the longitudinal direction of the cutting drum 10.

Combining the cutting knife 40 of the ⊂ type or ⊃ type in the form surrounding the sides of the pressing piece 30 of both ends of the cutting drum 10, the pressing piece 30 to the curved portion of the cutting knife 40 Combination groove 41 of the same shape as the cross-sectional shape of the pressing piece 30 so as to pass through so that the cutting knife 40 is moved in the longitudinal direction of the pressing piece 30 in a state in which the cutting knife 40 is not separated from the pressing piece 30. This is combined to make it possible.

After pressing the pressing plate 42 on the outer side of the cutting knife 40, the cutting knife 40 was fixed by the fixing means 43 is coupled to the side of the installation block 20.

Looking at the operation of the present invention with such a configuration as follows.

First, the box corrugated cardboard 1 which is printed by passing through a flexor drum printing machine (not shown) passes through the cutting drum 10 and the supporting drum 10 '. Since the cutting knife 40 is installed on the outer surface of the cutting drum 10 as described above, the cutting knife 10 passes through the cutting drum 10 and the supporting drum 10 'and is positioned at the position corresponding to the cutting knife 40. The cutout part 2 is formed in the box cardboard 1.

In addition, at the same time as the formation of the cutting portion 2 by the cutting knife 40 as described above to form a bent portion (3) to make the box corrugated cardboard (1) easy to fold by the pressing blade (32).

Therefore, since the box corrugated cardboard 1 is printed, the cutting part 2 and the bent part 3 can be formed at the same time as it is transported, so that processes such as separately loading or repositioning and supplying after printing can be eliminated. This is an advantage that allows for the formation of rapid cuts.

The rotary cutter device of the present invention, which operates as described above, is particularly convenient to change the position of the cutting part 2 by changing the size of the box to be manufactured, and specifically, of the box corrugated cardboard 1 to be cut out. When the width is narrowed or the widths of the cut portions 2 on both sides of the box corrugated cardboard are different from each other, the cutter device according to the present invention can be conveniently coped with.

That is, according to the present invention, since the pressing piece 30 is coupled to the coupling groove 41 formed in the curved portion of the cutting knife 40 so as to penetrate the fixing means 43 for fixing the cutting knife 40. After releasing and moving the cutting knife 40 in the longitudinal direction of the pressing piece 30, it is possible to move to a desired position, and when the fixing knife 43 is fixed again to fix the cutting knife 40 to work in a changed form. This will be possible.

And since the cutting knife 40 is combined in the form of wrapping the pressing piece 30, even if it is necessary to repair or replace the cutting knife 40, only by releasing the fixing means 43 can be easily removed, so the operation is very convenient. It is done quickly.
