The present invention relates to a composite panel, and more particularly relates to a manufacturing method of a composite panel.
In the decoration of home buildings and furniture, panels are often attached to outer surfaces of walls, columns and furniture to make them aesthetically pleasing or to provide waterproofing, sound insulation, heat insulation, and so on. One type of the panels used is a composite panel formed by attaching a plurality of parallel strips to a base sheet. Such composite panels can be bent by virtue of grooves between the strips to facilitate attachment to non-planer configurations such as curved art wall, edged corners, and round columns or poles.
In a conventional art, the composite panel is manufactured by roughly cutting a raw material into strips of approximate size, then finely cutting the strips into a precise shape, and then attaching the strips with the precise shape to a sheet one by one. However, since the long and thin strips tend to twist, shift and slide during and after cut, it is difficult to process them and may cause a problem of uneven processed shapes. On the other hand, attaching the strips to the sheet one by one is not only time consuming, but also prone to inconsistencies in alignment spacing and parallelism of the strips.
Accordingly, one objective of the present invention is to provide a manufacturing method of a composite panel so as to solve the problems in prior art.
In order to overcome the technical problems in prior art, the present invention provides a manufacturing method of a composite panel, comprising in sequence: a providing step of providing a flexible sheet, wherein the flexible sheet has an attachment surface; an attaching step of attaching at least one lamellar board to cover the attachment surface of the flexible sheet so as to form a lamellar structure layer on the attachment surface of the flexible sheet; and a cutting step of cutting a plurality of longitudinal grooves parallel to each other in the lamellar structure layer such that the plurality of longitudinal grooves are separated to each other to form the lamellar structure layer as a plurality of lamellar strips which are separate and parallel to each other such that the composite panel formed by the flexible sheet and the plurality of lamellar strips is able to be bent laterally into a curved configuration by virtue of the plurality of longitudinal grooves and flexibility of the flexible sheet.
In one embodiment of the present invention, the manufacturing method is provided, wherein in the providing step, the flexible sheet is a paper sheet, a fabric sheet, a plastic sheet, or a metal sheet.
In one embodiment of the present invention, the manufacturing method is provided, wherein in the attaching step, the lamellar structure layer is formed by a plurality of the lamellar boards which are arranged side by side in a lateral direction, and each of the lamellar boards has a longitudinal length not less than that of the attachment surface of the flexible sheet.
In one embodiment of the present invention, the manufacturing method is provided, wherein in the attaching step, outer surrounding edges of the lamellar structure layer extend beyond that of the attachment surface of the flexible sheet.
In one embodiment of the present invention, the manufacturing method is provided further comprising, after the attaching step, a trimming step of trimming the lamellar structure layer and the flexible sheet to a corresponding outer edge size.
In one embodiment of the present invention, the manufacturing method is provided, wherein in the attaching step, the lamellar board is a wood board, a fire-resistant board, or a fiber board.
In one embodiment of the present invention, the manufacturing method is provided, wherein in the cutting step, two or more of the longitudinal grooves are cut simultaneously in a single cutting process.
In one embodiment of the present invention, the manufacturing method is provided, wherein in the cutting step, each of the lamellar strips has a trapezoidal cross-sectional shape, a semicircular cross-sectional shape, a trapezoidal cross-sectional shape with chamfers, or a rectangular cross-sectional shape with chamfers.
In one embodiment of the present invention, the manufacturing method is provided further comprising, after the attaching step and before the cutting step, a flattening step of flattening an upper surface of the lamellar structure layer to a basic flat surface to facilitate the cutting step.
With the technical means adopted by the present invention, the manufacturing method of the present invention is to form the lamellar structure layer by attaching at least one lamellar board to the flexible sheet, and then to form the plurality of lamellar strips from the lamellar structure layer by cutting. In this way, the manufacturing method of the present invention does not require the time and effort of attaching the lamellar strips to the flexible sheet one by one, thus effectively improving the manufacturing efficiency. Moreover, since the cutting step in the present invention is performed on the lamellar structure layer which has been fixed on the flexible sheet, the problem of twisting, shifting and sliding will be avoided during the cutting step. In addition, there is no need to worry about the inconsistencies in alignment spacing and parallelism of the lamellar strips resulting from the conventional method of attaching the lamellar strips to the flexible sheet one by one.

Specifically, the flexible sheet 1 may be a paper sheet, a fabric sheet, a plastic sheet, a metal sheet, or other composite material flexible sheet. The fabric sheet may be, for example, woven fabric or non-woven fabric, both the paper sheet and the fabric sheet may be reinforced with plastic, natural rubber, environmentally friendly glue, fireproof glue, etc., and the metal sheet may be, for example, aluminum. However, the present invention is not limited to this, and the flexible sheet 1 may be made of other materials.
As shown in
Specifically, the lamellar board 2 is preferably a large-area sheet or board that has not been cut into strips. The lamellar board 2 may be a wood board, a fire-resistant board, or a fiberboard, such as a fireproof board, a solid wood board, a medium density fiberboard (MDF), a high density fiberboard (HDF), and other environmentally friendly recycled board. However, the present invention is not limited to this, and the lamellar board 2 may be made of other materials.
As shown in
Specifically, the cutting step S30 may be performed using various cutting processes, such as milling. As shown in
As shown in
With the technical means mentioned above, the manufacturing method of the present invention is to form the lamellar structure layer 3 by attaching at least one lamellar board 2 to the flexible sheet 1, and then to form the plurality of lamellar strips 32 from the lamellar structure layer 3 by cutting. In this way, the manufacturing method of the present invention does not require the time and effort of attaching the lamellar strips 32 to the flexible sheet 1 one by one, thus effectively improving the manufacturing efficiency. Moreover, since the cutting step S30 in the present invention is performed on the lamellar structure layer 3 which has been fixed on the flexible sheet 1, the problem of twisting, shifting and sliding will not occur easily during the cutting step S30, and there is no need to worry about the inconsistencies in alignment spacing and parallelism of the lamellar strips 32 resulting from the conventional method of attaching the lamellar strips to the flexible sheet one by one.
