Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bamboo products, and particularly relates to a bamboo tray. Background Art
[0002] At present, for the bent and special-shaped products made of bamboo on the market, such as bamboo trays, they are mostly realized by engraving and splicing bamboo laminated lumber. It is very difficult to form them by one-time overall bending and extension, because although bamboo has certain ductility in the longitudinal direction (bamboo fiber), its extensibility and ductility in the transverse direction are relatively poor. When processing tray products with a certain depth and rounded corners at four corners, the upper and lower surfaces at the outermost layer are subjected to the greatest extension force and are extremely prone to fracture and unable to form. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a bamboo tray formed integrally.
[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a bamboo tray, including a tray bottom, a tray wall and tray wings formed integrally, the tray wings are arranged on the periphery of the tray bottom, and the tray bottom and the tray wings are smoothly transitioned through the tray wall; the bamboo tray is made of bamboo multi-ply board.
[0005] Further, the included angle between one tray wall and the tray wall on its opposite side is 60° - 120°.
[0006] Further, the radius of curvature R1 at the connection between the tray bottom and the tray wall is 10 - 20 mm.
[0007] Further, the radius of curvature R2 at the connection between the tray wall and the tray wing is < R1.
[0008] Further, the bamboo multi-ply board includes at least three laminated bamboo sheet layers, and the thickness of the bamboo sheet layer is 0.2 - 1 mm.
[0009] Further, the number of the bamboo sheet layers is odd.
[0010] Further, the bamboo fiber directions of adjacent two bamboo sheet layers are perpendicular to each other.
[0011] Further, the bamboo sheet layer includes at least two spliced bamboo sheets, and the bamboo fiber directions of the bamboo sheets in the same bamboo sheet layer are parallel to each other.
[0012] Further, an adhesive layer is provided between the bamboo sheet layers.
[0013] The beneficial effect of the utility model lies in that: the bamboo tray provided by the utility model realizes the smooth transition between the tray bottom and the tray wings through the tray wall, and the radii of curvature of the two formed bends are relatively small, and integral forming can be realized.

[0017] Label description:
[0018] 1, bottom plate; 2, side wall; 3, wing plate. Specific embodiment
[0019] To describe in detail the technical content, achieved purpose and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the drawings.
[0020] Please refer to Figures 1 to 3 , a bamboo pallet, comprising an integrally formed bottom plate 1, side wall 2 and wing plate 3. The wing plate 3 is arranged on the periphery of the bottom plate 1, and the bottom plate 1 and the wing plate 3 are smoothly transitioned through the side wall 2; the bamboo pallet is made of bamboo multi-layer board.
[0021] From the above description, it can be seen that the beneficial effect of the present invention is that: the bamboo pallet provided by the present invention realizes the smooth transition between the bottom plate and the wing plate through the side wall, and the curvature radii of the two bending parts formed by the transition are relatively small, and integral forming can be realized.
[0022] Furthermore, the bottom plate 1 and the wing plate 3 are parallel to each other.
[0023] Furthermore, the curvature radius R1 at the connection between the bottom plate 1 and the side wall 2 is 10 - 20 mm. Such as 11 mm, 13 mm, 14 mm, 15 mm. Preferably 12 - 16 mm.
[0024] Furthermore, the curvature radius R2 at the connection between the side wall 2 and the wing plate 3 < R1.
[0025] Furthermore, the included angle between one side wall 2 and its opposite side wall 2 is 60° - 120°. Such as 65°, 75°, 85°, 90°, 100°, 105°, 110°, 115°. Preferably 70° - 80°.
[0026] From the above description, it can be seen that by setting the curvature radii at the connection between the bottom plate and the side wall, and at the connection between the side wall and the wing plate, a smooth transition with a large curvature and a small radius is formed, and then an integrally formed bamboo pallet is obtained. The included angle between the side walls is designed in cooperation with the curvature radii at the four corners.
[0027] Furthermore, the bamboo multi-layer board includes at least three laminated bamboo sheet layers, and the thickness of each bamboo sheet layer is 0.2 - 1 mm, such as 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm.
[0028] As can be seen from the above description, when using bamboo sheet layers with a relatively thin thickness, the density difference within a single layer is small, and the bamboo multi-layer board formed by combination is not prone to deformation and cracking when used to prepare bamboo trays.
[0029] Furthermore, the number of bamboo sheet layers is odd. Preferably, the number of bamboo sheet layers is 3 - 7, and the thickness is 0.6 - 0.8 mm. More preferably, the number of bamboo sheet layers is 5, and the thickness is 0.6 mm.
[0030] Furthermore, the bamboo fiber directions of adjacent two bamboo sheet layers are perpendicular to each other.
[0031] As can be seen from the above description, using the method of arranging the bamboo fiber directions perpendicular to each other between layers is beneficial to improving the physical properties and stability of the overall material after combination, and ensuring the quality of bamboo trays.
[0032] Furthermore, each bamboo sheet layer includes at least two spliced bamboo sheets, and the bamboo fiber directions of the bamboo sheets in the same bamboo sheet layer are parallel to each other.
[0033] As can be seen from the above description, according to the width of the bamboo sheets and the dimensions of the required products, multiple bamboo sheets can be used to splice the width to form bamboo sheet layers.
[0034] Furthermore, an adhesive layer is provided between the bamboo sheet layers.
[0035] As can be seen from the above description, the adhesive layer is composed of glue and is used to bond (fit) the upper and lower bamboo sheet layers.

[0038] The radius of curvature R1 at the connection of the tray bottom and the tray walls is 15.5 mm; the radius of curvature R2 at the connection of the tray walls and the tray wings is 12.5 mm; the included angle α between one tray wall and its opposite tray wall is 80°;
