Through this, the shaft bar 302 is connected to the cutting blade rotation shaft 100 and the timing belt 303, so that the cutting blade 300 has a high-speed rotational power.

Here, the cutting blade 300 is mounted on the cutting blade driving body 301 and the cutting blade cover 304 is covered and the bolt 305 can be fastened.

The upper and lower conveying means 400 for cutting the corrugated cardboard 8 while being engaged with the supporting roller 350 under the cutting blade 300 by transferring the rotating cutting blade 300 to the lower side is one rotation plate as shown in FIG. 6. The worm gear 409 rotated by the operation of the lever 408 is installed on the rotation support 410, and the worm gear 409 is provided with a worm wheel 411 installed on the upper and lower feed shafts 412. The upper and lower feed shafts (412) are engaged with the rotary force

In the cutting blade upper and lower feed shaft 412, a bearing cover 414 having a bearing 413 is attached to the conveying frame 200, but a main gear 415 is installed inside the main blade 415. As the pivoting table 404 is engaged with the driven gear 403 of the pivoting body 402, the pivoting table 404 is rotated up and down to transfer the cutting blade 300 up and down.

Left and right width adjusting means 500 for adjusting the cutting width is rotatably installed between the rotation support 501 installed on one side of the moving metal 202, the feed shaft 502 and the pinion on both sides of the feed shaft 502 The gear 503 is installed, and the pinion gear 503 is engaged with the rack 204 installed on the upper guide rod 203, thereby allowing the transfer frame 200 to be manually moved left and right by operating the lever 504. It becomes possible.

When the cutting blade 300 wears, the grinding machine 600 for grinding the cutting blade 300 is provided with a pneumatic cylinder 603 in the grinding machine fixing bracket 602 fastened to the grinding fixture 406 by a bolt 601.

Here, the pneumatic cylinder 603 is installed so that the cylinder shaft 605 penetrates to a separate cylinder fixing bracket 604, and the cylinder fixing bracket 604 penetrates the long groove 605 of the polishing machine fixing bracket 602 to have a bolt ( 606) it is possible to adjust the distance in the cutting edge direction.

Meanwhile, a transfer plate 607 is installed at the front end of the cylinder shaft 605 of the pneumatic cylinder 603, and a pair of polishing rollers 609 and 610 are rotatable on the upper and lower fixing rods 608 on the side of the transfer plate 607. Although the polishing rollers 609 and 610 are installed symmetrically with each other so that the polishing surface 611 abuts outwardly by the cutting edge surface 306 so that the polishing surface 611 abuts on both cutting edge surfaces 306 as shown in FIG. Both cutting edges 306 of 300 can be polished at the same time.

Referring to the operating state of the present invention in this configuration is as follows.

When the operation switch of the control panel 12 of the support 2 is turned on and the driving motor 3 is driven, the cutting blade 300 rotates as the cutting blade rotation shaft 100 rotates.

At this time, as shown in Figure 7, a pair of fold line forming rollers 10, 11 and the support roller 350 is provided with a rotating shaft 13 is not shown in the figure, but the upper forming roller 10 by a power transmission means such as a chain In the counterclockwise direction, the lower forming roller 11 and the supporting roller 350 can rotate while being engaged in the clockwise direction.

When the cardboard 8 is inserted between the forming rollers 10 and 11 in this state, the fold line 13 of the upper forming roller 10 is engaged with the lower forming roller 11 in the cardboard 8 and the fold line At the same time as forming the (9) it is transferred to the cutting edge (300).

Here, when the worm gear 409 of the rotating plate 6 is rotated, the main gear 415 rotates the driven gear 403 as the cutting blade upper and lower feed shafts 412 rotate so that the pivoting table 404 rotates. The cutting blade 300 is transferred to the lower portion so that the cutting blade 300 is rotated while being seated on the cutting blade inserting portion 351 of the lower support roller 350 as shown in FIG. 11.

Therefore, the corrugated cardboard 8 transported to the cutting blade 300 by the forming rollers 10 and 11 is cut by the cutting blade 300 while being supported by the interlocking support roller 350 to the corrugated cardboard 8 when cutting. Since no external force is applied, the bones are not broken at all and the completeness of the product can be secured.

In other words, by cutting the corrugated cardboard 8 while engaging a pair of upper and lower cutting blades in the related art, it is possible to solve the fracture of the corrugated cardboard by applying an external force to the corrugated cardboard.

Also, in order to adjust the cutting width, when the lever 504 of the left and right width adjusting means 500 is rotated as shown in FIG. 8, the pinion gear 503 rotates along the rack 204 of the guide rod 203. By transporting the transport frame 200 while being transported, the left and right widths of the cutting blade 300 can be manually adjusted.

On the other hand, the grinding of the cutting blade 300 operates the pneumatic cylinder 603 to the extent that the polishing surface 611 of the polishing rollers 609 and 610 abuts against the cutting blade surface 306 as shown in FIG. 10. ).

At this time, the transfer plate 607 has guide rods 612 installed on both sides of the cylinder shaft 605 guided to the polishing machine fixing bracket 602 so that the transfer plate 607 does not flow, so that the polishing rollers 10 and 11 are It is always possible to contact the cutting blade surface 306.

When the polishing rollers 609 and 610 come into contact with both cutting edge surfaces 306, the polishing rollers 609 and 610 rotatably installed on the fixing table 608 are subjected to severe frictional resistance by the cutting blade 300 rotating at high speed. The cutting blade surface 306 can be polished while rotating at low speed so as not to be generated.

When the cutting of the cutting blade 300 is made as described above, the pneumatic cylinder 603 is operated to restore the polishing rollers 609 and 610 to their original positions.

According to the present invention, since the cutting of the corrugated cardboard is made by the cutting blade of the outer blade type engaged with the support roller, it can be neatly cut in a circular state without the breakage of the cutting blade. One-touch operation makes it easy to grind the cutting blade on the fly, which increases work efficiency.
