Description

A fluting device for green printed matter cardboard

Technical Field

The utility model relates to a packing carton technical field, concretely relates to fluting device for green printed matter cardboard.

Background

Along with the development of society, people have higher and higher quality requirements on gift boxes, the gift boxes need to be subjected to a grooving process in the processing process, the grooving process is usually processed through a grooving machine, at present, the grooving machine can only be used for simply forming a V-shaped groove, once the formed V-shaped groove meets a thicker paperboard with the thickness of 1.5-2.0mm or even above, the V-shaped groove is very easy to wrinkle after paper is mounted, the paper is tightened to be difficult to reach the angle required after the box is folded, and the forming is very difficult.

Disclosure of Invention

For solving the prior art problem, the utility model discloses an improve grooved shape and angle, make the groove of seting up be the U type, the shape of the cardboard is removed to the shovel that can be darker, and the angle of folding into after letting the groove mount paper is more abundant, and the shaping is better looking, and the paper line of mounting paper back groove more tends to stably from top to bottom makes simultaneously, can not the fold.

The utility model discloses specifically adopt following technical scheme:

a slotting device for green printed paper boards comprises two cutter heads and a cutter frame;

grooves are symmetrically formed in two ends of the upper surface of the tool rest, and the two tool bits are embedded into the two grooves respectively;

two the tool bit is kept away from the one end of knife rest all is provided with fluting portion, fluting portion includes first fluting sword and second fluting sword.

The further scheme is that the first slotting blade is provided with a blade relief angle R1, and R1 is more than or equal to 8 degrees and less than or equal to 10 degrees.

The further scheme is that the second grooving blade is provided with a blade relief angle R2, and R2 is more than or equal to 3 degrees and less than or equal to 5 degrees.

The further scheme is that limiting holes are formed in the side faces of two ends of the tool rest and communicated with one side of the groove, and limiting rods are connected to the limiting holes in a threaded mode.

The further scheme is that one end, far away from the cutter head, of the limiting rod is provided with anti-skidding lines.

The further proposal is that the tool rest is also symmetrically provided with two fixing holes.

The utility model has the advantages that:

the groove is made to be U-shaped by improving the shape and the angle of the groove, the shape of the paper board can be deeply eradicated, the folded angle after the groove is provided with paper for mounting is more abundant, the forming is better, and the paper lines of the groove after the upper paper mounting and the lower paper mounting are more stable and cannot be folded;

through setting up spacing hole and gag lever post, realize spacing to the tool bit, prevent that the tool bit from breaking away from the recess.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-5, an embodiment of the present invention discloses a slotting device for green printed paper boards, which includes two tool bits 1 and a tool rest 2, wherein two ends of the upper surface of the tool rest 2 are symmetrically provided with grooves 20, and the two tool bits 1 are respectively embedded in the two grooves 20; the one end that knife rest 2 was kept away from to two tool bits 1 all is provided with the fluting portion, and the fluting portion includes first fluting sword 10 and second fluting sword 11.

Through improving grooved shape and angle, the groove that makes to set up is the U type, and the shape of removing the cardboard that can be darker lets the angle of converting into after the groove is mounted paper more spacious, and the shaping is better looking, and the paper line of mounting the groove after the paper more tends to stably from top to bottom simultaneously, can not the fold.

In the embodiment, the first grooving edge 10 is provided with an edge relief angle R1, and R1 is more than or equal to 8 degrees and less than or equal to 10 degrees; the second grooving blade 11 is provided with a blade relief angle R2, and R2 is more than or equal to 3 degrees and less than or equal to 5 degrees. In order to ensure a better grooving effect.

In this embodiment, the side surfaces of the two ends of the tool rest 2 are provided with a limiting hole 3, the limiting hole 3 is communicated with one side of the groove 20, and the limiting hole 3 is in threaded connection with a limiting rod 4. Carry on spacingly through gag lever post 4 to tool bit 1, prevent that tool bit 1 from breaking away from recess 20.
