Compared with traditional hot melt adhesive edge banding technology, laser edge banding technology has the advantages of seamless connection, high durability, environmental protection and low maintenance cost. Therefore, this technology is widely used in high-end furniture manufacturing and occasions requiring high-quality edge banding. However, the existing laser edge banding technology still has some shortcomings.

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0022] like Figures 1 to 3 As shown, a high-efficiency laser edge banding production line for plate edge banding described in this embodiment is applied to the edge banding of the cut surface of the plate, and includes an edge banding device and an extrusion processing device; the extrusion processing device includes an extruder die head 11, a first cooling mechanism, a gluing mechanism, and a second cooling mechanism sequentially arranged along the moving direction of the edge banding strip; the extruder die head 11 is configured to extrude the required edge banding strip; the first cooling mechanism is configured to cool down the edge banding strip extruded by the extruder die head 11; the gluing mechanism is configured to back-coat the edge banding strip with laser hot melt adhesive; the second cooling mechanism is configured to cool down the edge banding strip back-coated with laser hot melt adhesive;

[0023] The edge banding device includes a rolling assembly, a heat preservation component 22, a refractor 23 and a laser generator 24; the rolling assembly is configured to roll the edge banding strip so that the edge banding strip fits on the cut surface of the plate; the heat preservation component 22 is configured to keep the edge banding area warm; the refractor 23 is configured to refract the laser beam generated by the laser generator 24 so that the laser beam is irradiated on the desired edge banding area.

[0024] Specifically, in actual application, the high-efficiency laser edge banding production line of this embodiment extrude the edge banding strip required to perform edge banding on the cut surface of the plate through the extruder die head 11, and the extruded edge banding strip first passes through the first cooling mechanism for cooling and lowering the temperature so that the edge banding strip can be reliably shaped, and then the cooled edge banding strip passes through the gluing mechanism, at which time the gluing mechanism coats the back of the edge banding strip with laser hot melt adhesive, and the laser hot melt adhesive can be dissolved under the energy generated by the laser beam, so that the subsequent edge banding strip can perform edge banding on the cut surface of the plate, and then the edge banding strip with the laser hot melt adhesive on the back passes through the second cooling mechanism, and the second cooling mechanism cools and lowers the temperature of the edge banding strip and the laser hot melt adhesive, so that the laser hot melt adhesive is shaped on the back of the edge banding strip;

[0025] The edge banding strip cooled by the second cooling mechanism is transported to the cutting surface of the plate, and the laser generator 24 generates a laser beam. After being refracted by the refractor 23, the laser beam is irradiated on the edge banding area where the edge banding strip contacts the cutting surface of the plate, so that the laser hot melt adhesive on the back of the edge banding strip is dissolved, and then the rolling assembly rolls the edge banding strip so that the edge banding strip is adhered to the cutting surface of the plate through the dissolved laser hot melt adhesive, so that the edge banding strip and the plate are firmly bonded together. During the dissolution of the laser hot melt adhesive, the thermal insulation component 22 insulates the temperature of the edge banding area to reduce the heat loss generated by the laser beam, so that more heat is concentrated in the edge banding area, thereby accelerating the dissolution of the laser hot melt adhesive. As the edge banding strip is adhered, the thermal insulation component 22 moves accordingly; in this way, the seam connection is achieved and the production efficiency is improved.

[0026] like Figure 1 and Figure 2 As shown, this embodiment provides a first cooling mechanism and a second cooling mechanism for cooling and lowering the temperature, and provides a glue coating mechanism between the first cooling mechanism and the second cooling mechanism, so that laser hot melt adhesive can be pre-coated on the back of the edge banding strip after the edge banding strip is extruded, thereby improving the edge banding efficiency of subsequent edge banding operations, and at the same time making the edge banding strip cooler, which is beneficial to reducing the occurrence of glue lines during edge banding operations and improving the quality of the edge banding strip.

[0027] In this embodiment, the edge sealing area is insulated by providing a heat-insulating member 22, thereby reducing heat loss in the edge sealing area and ensuring that more heat is concentrated in the edge sealing area, thereby reducing the power consumption of the laser generator 24 and improving the edge sealing efficiency.

[0028] For example, a laser generator 24 with a laser power of 21-28 J and a wavelength of 1064 cm-1 is used.

[0029] like Figure 1 and Figure 2 As shown, in the high-efficiency laser edge banding production line of this embodiment, in some embodiments, the glue coating mechanism includes a coating bracket 131, two first pressing rollers 132 rotatably mounted on the coating bracket 131, and a glue coating roller 133 rotatably mounted just above the two first pressing rollers 132. Specifically, the edge banding strip is guided and supported by the rotation of the two first pressing rollers 132, so that the glue coating roller 133 can reliably coat the laser hot melt adhesive on the back of the edge banding strip.

[0030] like Figure 1 and Figure 2As shown, in the high-efficiency laser edge banding production line of this embodiment, in some embodiments, the second cooling mechanism includes a cooling bracket 141, a guide roller 142 rotatably mounted on the cooling bracket 141, and a fan 143 fixed above the guide roller 142. Specifically, in this embodiment, the guide roller 142 guides the edge banding strip, and the fan 143 air-cools the edge banding strip passing through, thereby cooling the edge banding strip and the laser hot melt adhesive.

[0031] like Figure 1 and Figure 2 As shown, in the high-efficiency laser edge banding production line of this embodiment, in some embodiments, the number of fans 143 is multiple, and the multiple fans 143 are arranged side by side at intervals along the moving direction of the edge banding strip. In this embodiment, multiple fans 143 are arranged to improve the cooling effect of the edge banding strip and the laser hot melt adhesive.

[0032] like Figure 1 and Figure 2 As shown, in the high-efficiency laser edge banding production line of this embodiment, in some embodiments, the first cooling mechanism includes a cooling water tank 121 and a coolant disposed in the cooling water tank 121. Specifically, the coolant is water, and the edge banding strip extruded by the extruder die head 11 is passed into the cooling water tank 121, and the edge banding strip is cooled quickly by water cooling to facilitate the subsequent gluing operation.

[0033] like Figure 1 and Figure 3 As shown, in the high-efficiency laser edge banding production line of this embodiment, in some embodiments, the rolling assembly includes two second pressing rollers 211 arranged side by side at intervals and a third pressing roller 212 arranged between the two second pressing rollers 211, and the diameter of the third pressing roller 212 is smaller than the diameter of the second pressing roller 211. In this embodiment, the edge banding strip is pressed by arranging two second pressing rollers 211 and one third pressing roller 212, so that the edge banding strip is more flatly attached to the cut surface of the plate.

[0034] In the high-efficiency laser edge banding production line of this embodiment, in some embodiments, the thermal insulation component 22 is an arc-shaped aluminum foil foam sandwich panel. With this arrangement, the ability of the aluminum foil foam sandwich panel to reflect the laser beam is utilized to ensure that more heat is concentrated in the edge banding area, thereby effectively reducing heat loss.

[0035] like Figure 1 and Figure 3As shown, in the high-efficiency laser edge banding production line of this embodiment, in some embodiments, the edge banding device further includes an exhaust gas collection mechanism, the exhaust gas collection mechanism includes an exhaust gas collection cover 251 and an activated carbon adsorption box 252 connected to the exhaust gas collection cover 251, and the rolling assembly and the heat preservation member 22 are located in the exhaust gas collection cover 251. Specifically, during the edge banding process, the activated carbon adsorption box 252 works to generate adsorption force in the exhaust gas collection cover 251, and the harmful gases (such as hydrogen chloride (HCl) and volatile organic compounds (VOC)) generated during the edge banding process are collected and processed in time, thereby reducing the pollution of the environment caused by the edge banding operation, and the edge banding operation is more environmentally friendly.

[0036] The above is only a preferred embodiment of the present utility model, so any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the protection scope of the present utility model patent application.
