Description

Cutting table {TABLE FOR CUTTING}

The present invention relates to a cutting table, and more particularly, to a cutting table capable of cutting various types of objects to be cut, and automatically suctioning and filtering powder or dust generated in the process.

In general, plywood, MDF panel (Medium Density Fiber Panel), LPM panel (Low Pressure Melamine Panel), PB panel (Particle Board Panel), etc. are widely used as various building materials and furniture materials.

These plate materials (板材) have high strength as well as good workability, and are suitable for bonding patterned sheets, so they have been widely used in recent years.

On the other hand, these plate materials are cut to a predetermined size by a plate cutter.

The cutter has a frame, and a fixed table is installed on the frame.

The fixed table supports one side of the plate to be cut, and an installation hole is formed on its upper surface.

And rotary saw blades are installed in a line in the installation hole of the fixed table.

The rotary saw blade protrudes more than the upper surface of the fixed table, and serves to cut the plate.

Here, the rotary saw blade is rotated at a high speed by a driving motor installed under the fixed table.

And on the upper surface of the fixed table, an early stage that can move left and right is installed. The early stage has a reference plane that can support one side of the plate.

The reference plane is a plane that serves as a reference when cutting the plate, and allows the plate to be cut to a set dimension based on this.

Here, the reference plane is parallel to the rotary saw blade, and the distance with the rotary saw blade is adjusted as the early stage moves left and right.

On the other hand, on one side of the fixed table, a movable table is installed so as to move forward and backward.

The movable table supports the other side of the plate material, and enables the supported plate material to move in the forward and backward directions with respect to the rotary saw blade.

Here, the movable table is installed to be movable forward and backward by a guide device, and the guide device is composed of a guide rod fixed to the frame, and a slider that moves linearly along the guide rod and is fixed to the bottom surface of the movable table.

In particular, the guide rod is elongated toward the front and rear of the frame so that the front and rear movement distance of the movable table can be increased.

However, such a conventional cutter does not include a means for collecting powder or dust generated in the process of cutting the plate, thereby harming the health of workers and polluting the air.

Therefore, there is an urgent need to develop a cutting device capable of collecting powder or dust generated in the process of cutting a plate to improve the working environment and protect workers and the atmosphere.
