Cardboard V Grooving Machine

Cardboard V Grooving Machine

Whether you are producing rigid boxes/hardcovers, creating customized cartons, or designing attractive packaging cases, the cardboard V-grooving machine could be your helpful assistant, enabling you to complete projects more efficiently and quickly.

There are various types of cardboard grooving machines on the market.

How do you choose the most suitable type?

Read this guide to buy your dreamy cardboard grooving machine for rigid/gift box production or hard case making.

Definition

The cardboard V groove cutting machine is a standard piece of packaging equipment in the gift box industry.

Its blades remove excess fibers from the cardboard sheet surface along a path, forming V grooves.

With these V grooves, the cardboard is foldable to form a three-dimensional cardboard box.

Cardboard groover machines have similar functions to conventional creasing machines, but compared with the latter, it has the following advantages:

• Sharp edges & corners, a simple & beautiful appearance after forming.
• Rebound force reduction of the paperboard for anti-deformation.
• Pre-folding process is unnecessary, and subsequent corner pasting is more convenient.

Application

A manual paperboard grooving machine is suitable for manual grooving sample boxes, helping to develop innovative packaging designs, gift box prototypes, and rigid box samples.

Semi-auto cardboard V groove cutting machines are widespread in gift box & case proofing or small batch production.

An automatic cardboard grooving machine is useful for batch production of rigid boxes or hardcovers, such as luxury goods, mobile phones, wine, tea, shoe boxes, and bookcases.

Types

There are 3 types of V grooving machines for cardboard:

Automatic

Such an automatic grooving machine grooves cardboard & MDF sheets in batches.

It is essential equipment for the mass production of rigid boxes, gift boxes, hardcovers, and hard cases.

Working Principle

Before understanding how it works, let us first roughly digest its structure according to the schematic below.

Such an automatic rigid box grooving machine consists of the following components:

• Frame
• Board Baffle (Magazine)
• Infeed Belts
• φ60cm Drum
• Drum Belts
• Cutter Blades
• Outfeed Belts
• Motor
• Chain & Gear Drive
• Leveling Feet

A worker manually adds board sheets to the baffle magazine first;

Then the infeed belts convey sheets to the surface of a φ60cm drum;

As the drum rotates, cardboard, KT board, or MDF sheets pass through diagonally opposed cutters;

These cutter blades remove excess fibers from the sheet surface;

Forming V grooves:

Features

Such a rigid box grooving machine adopts an automatic correction combination (belt, anti-deflection wheel, board baffle magazine).

Thus, you could directly place the sheets into the magazine, and these sheets are automatically corrected before passing through the V-groove cutter, ensuring the accuracy & uniformity of grooving.

The groove blade holder introduces a unique structure design, ensuring:

• No error in grooving;
• Back and forth shaking of sheets is avoidable;
• Blade holder & drum damage can be avoided during debugging.

And the blade position is adjustable via the knob.

There are visible scales under the knob, which is convenient enough.

Imported tungsten steel cutting blades ensure long grooving life & excellent grooving effect.

In addition, the machine can automatically clean up and collect waste, and the recycled waste can be sold to pay part of your electricity bill.

Imported high-quality transmission bearings ensure extremely low noise & eccentricity when the machine operates at high speed.

Gear & chain drive replaces belt drive to improve machine quality and extend service life.

Semi-Automatic

A semi-automatic V-groove cutter machine is useful for prototyping gift & rigid boxes, and some customers also use it for small-batch rigid box grooving.

Three types are available for your choice:

Economical Pneumatic Control

Working Principle

First, let’s show you the following figure.

Converting a cardboard sheet to V-groove cardboard on this machine involves three steps:

• Corner Cutting

• Vertical Grooving

• Horizontal Grooving

Features

A 32mm diameter air cylinder controls the cutter stroke.

With high-precision slide rails, a high-pressure output rodless piston cylinder, and an aviation aluminum workbench, they ensure high grooving accuracy & good prototyping effect.

Its automation lies in corner cutting, cardboard sheet pressing, and V-groove cutting; the latter two motions must be completed by hand on the manual model.

The photo below displays its program control screen.

The parameters are adjustable, including cutting time/stroke, and the control is convenient.

As the grooving angle needs to change in real production, its blade holder is user-friendly, with fast knife changeover & high stability, minimizing downtime.

The following features are also attractive to clients.

Furthermore, this cardboard groove cutter is capable of grooving 4mm thick MDF, the same thickness supported by Kolbus NM 101 of Germany:

As shown in the video above, as long as your compressed air source pressure is stable, such pneumatic control models can also meet your requirements for high-quality cardboard grooving.

If your compressed air source pressure is unstable, the cutter will break easily, and you will need to replace the blade frequently.

Parameters

Item	Pneumatic Control Semi-auto Cardboard Grooving Machine
Speed	0.5s/cut
Cardboard Size	Width: 0-700mm/0″-27.56″ Thickness: 0-8mm/0″-0.315″
Board Material	Gray Cardboard, White Cardboard, KT Board, MDF

Tolerance	0.05mm
Max. Corner Height	75/150mm
Voltage	220/380V, 50/60Hz
Air Pressure	0.5Mpa-0.8Mpa | 5-8 Bar

Mid-range Servo Driven

A servo motor controls the cutter’s back-and-forth cycle, making it more precise, smooth, and stable.

• Cutter circulation does not require an air compressor and is no longer affected by air pressure.
• Smoother blade back-and-forth movement and blade loss rate reduction.
• Consistent groove depth without a difference.
• Optional manual/automatic controls.
• Adjustable grooving interval according to different materials & thickness.
• Security protection.

Its price is higher than the pneumatic control one.

If you have extremely high requirements for precision, stability, and smoothness, we recommend you choose this type.

High-end Dual Purpose

This is the latest model launched in 2024, which is compatible with both rigid box & case board sheet grooving.

It integrates all the features of the previous two and also adds some unique selling points.

The most attractive point is that this model can not only groove board sheets for gift boxes but also slot board sheets for hard covers or cases; it’s a dual-purpose model.

Compared to the previous two semi-automatic models, this machine does not require manual size adjustments; instead, simply input the size on the screen.

As shown in the HMI (English Customizable):

Since it also uses servo-controlled blade circulation, it also performs perfectly in grooving.

Additionally, we can customize the touchscreen HMI according to your requirements and include your company logo in the interface.
