Description

Edge banding machine {An edge banding machine}

The present invention relates to an edge banding machine, and in particular, an adhesive process for press-bonding an edge band for surface decoration to an edge (border) of a panel product, and an end of the bonded edge band according to the thickness of the product edge. The present invention relates to an edge banding machine including a trimming process for cutting a slicing process, and a buffing process for removing adhesives on edges of trimmed panels.

Currently, artificial molded wood, so-called MDF panel, is widely used as furniture material. The MDF panel is thermally transferred to transfer paper with various colors and patterns such as wooden patterns on the front and back surfaces, but the surface of the raw material remains the same. It is exposed and its appearance is bad. Therefore, in order to finish the rim of the panel, a finishing band is attached to the side with an adhesive. The equipment used for this task is commonly referred to as edge-banding machine.

Existing edge banding machine has a difficult finish to clean the edge of the edge band attached to the panel. That is, the existing edge banding machine has a problem that the cutting edge of the edge band is not cut cleanly when the edge cutting device is to cut the front and rear edge of the edge band at a time.

In addition, the chip trimmed by the trimming device of the conventional edge banding machine is not discharged smoothly, but is wound around the axis of the rotary support plate disposed adjacent to the trimming cutter, thereby preventing rotation of the rotary support plate, thereby stopping the conveyance of the panel. Finally, there was the inconvenience of stopping the equipment and restarting the chip.

Therefore, the present invention considers the problems of the conventional edge banding machine described above, and it is possible to cleanly cut the edge of the edge band according to the same as the tip of the panel regardless of the thickness of the edge band, and discharge the chip smoothly during the trimming process. The purpose is to provide an edge banding machine that can prevent the equipment from being interrupted by the chip.

In order to achieve the above object, the present invention, the edge band is attached to the edge portion of the panel conveyed by the conveyor and the transfer roller in the edge banding machine for cutting the rim to the length and thickness of the panel, the conveying along the conveyor Edge band attaching means for contacting the edge of the panel with the application roll to apply the adhesive to the edge of the panel and pressing and attaching the edge band to the edge of the panel to which the adhesive is applied with a pressure roller, and the cutter by the expansion and contraction operation of the pneumatic cylinder. Edge cutting device for cutting the leading edge of the edge band attached to the edge of the panel moving along the conveyor while the elevator moves up and down, the edge band of the panel transferred along the conveyor to the thickness of the panel 1 pair of trimmings, and blows the trimmed chips with air to discharge the cut chips to the outside. It comprises a device and a buffing device for removing the adhesive on the edge of the panel passing through the trimming device through the buffing wheel.

The edge cutting device is controlled by a control panel and is configured to cut the front and rear edge bands of the edge band of the panel being moved along the conveyor while the pneumatic cylinder moves along the guide rod.

As described above, when the edge banding machine has a thick edge band, the edge band end surface attached to the panel is cleanly finished by cutting the front and rear ends of the edge band in two stages. And, by smoothly discharging the chip into the chip discharge groove through the air nozzle in the trimming device it can solve the problem that the chip is wound to interfere with the operation of the rotating disc.
