CN2504058Y - Planning cutting bamboo sheet by spreading whole bamboo - Google Patents

Abstract

The utility model relates to a sliced bamboo slice from an unfolded bamboo flat-plate of an entire bamboo tube, which is obtained by cutting off a bamboo tube, removing the inner and outer bamboo joints, bamboo green coverings and tabasheer, then slotting the bamboo tube and then loading the slotted bamboo tube into an unfolding mold to be flattened and agglutinated into a square material after being softened by a high temperature, and at last slicing the square material. The utility model is characterized in that the breadth of the bamboo slice is basically equal to the circumference of the bamboo tube. Compared with the bamboo slice obtained by using a rotary cutting, the length of the utility model is obviously increased. When being used for a surface decoration, the utility model does not need piecing out lengthwise, and therefore the texture on the surface of the bamboo slice is more natural and artistic.

Description

Whole bamboo spreading bamboo veneer slicing thin slice

The utility model belongs to a kind of bamboo wood product in the forestry products processing industry.

Bamboo, particularly mao bamboon are a kind of speed life, high yield, high-quality, be easy to upgrade the important forestry products of recovering natural resources.Because bamboo is a kind of hollow and thin-walled self-sow material, in order to reach the purpose that large-scale industry utilizes, existing multiple now it is processed into the technology of sheet material after launching.In multiple expansion technique, mainly contain the dull and stereotyped pressurization half bamboo method of development, split the thin bamboo strip method of development and rotary-cut method of development three major types.

At present, the technology with the dull and stereotyped pressurization of mao bamboon half bamboo expansion making wood-based plate is representative with " CNZL 87100368 bamboo plywood manufacture methods " and " CNZL 91108203 improved technology for making ply-bamboo " mainly.Technological core in these two kinds of patented methods all is that the subdivision thick bamboo tube after softening the processing is directly sent into once pressurization expansion in two flat boards.With the bamboo wood that this method is launched, because existence crackle clearly, it is not ideal enough to launch quality, though do not influence the manufacturing that is used for the glued board series products, and be not suitable for slicing processing.Owing to can't launch whole thick bamboo tube with this technology, therefore, individual bamboo clappers breadth after it launches also is restricted.

Owing to be subjected to the restriction of thick bamboo tube geometry, the length of thick bamboo tube can only be below 1000mm when rotary-cut launched.

Purpose of design of the present utility model is to obtain a kind of breadth and the big as far as possible whole bamboo spreading bamboo veneer slicing thin slice of high-quality of length, and a kind of novel face decoration material is provided.

Technical solution of the present utility model is: thick bamboo tube is blocked, and machining is removed inside and outside joint and surf green, tabasheer, cracks; Behind hot mastication, thick bamboo tube sent in the expansion mould as shown in Figure 1 and flatten, obtain the whole bamboo spreading bamboo veneer of no naked eyes visible crack; To put in order the bamboo spreading bamboo veneer and compose square bar, put into the slicing of slicing equipment, can obtain the whole bamboo spreading bamboo veneer slicing thin slice of high-quality.The principal character of the whole bamboo spreading bamboo veneer slicing thin slice of high-quality is that its fabric width equates substantially with the girth of thick bamboo tube.

Exemplary embodiments:

Intercepted length is 2500mm, the diameter mao bamboon more than 80mm, and the inside and outside ring of usefulness machinery removal thick bamboo tube and surf green, tabasheer are left a narrow slit along the length direction of thick bamboo tube.After placing high temperature about 180 ℃ down softening the finished thick bamboo tube, make thick bamboo tube and launch relative motion of mould generation with the processing mode shown in the accompanying drawing 1, thick bamboo tube can flatten under the effect of mould gradually, obtain no naked eyes visible crack, thickness 2～8mm, fabric width are greater than the whole bamboo spreading bamboo veneer of 240mm.To put in order the bamboo spreading bamboo veneer and compose square bar, put into the slicer slicing, can obtain the whole bamboo spreading bamboo veneer slicing thin slice of length * wide * thick=2500 * 240 * (0.2～1.0) mm.

The description of the drawings:

The whole bamboo method of deploying schematic diagram that Fig. 1 is.(1) is the expansion mould among the figure, and (2) are thick bamboo tube;

Fig. 2 is whole bamboo spreading bamboo veneer slicing thin slice finished product.

The utility model is compared with the bamboo wood thin slice that obtains with rotary cutting method, and length obviously increases, and is used for the surface dress Decorations, owing to need not Lengthwise joint, the texture of plate face is more natural, attractive in appearance.

Claims (1)

1. one kind is blocked thick bamboo tube, acromere and surf green, tabasheer in machining is removed, crack, behind hot mastication, send into and launch to flatten in the mould, compose the whole bamboo spreading bamboo veneer slicing thin slice that obtains after the square bar slicing, it is characterized in that its fabric width equates substantially with the girth of thick bamboo tube.
