Abstract
The utility model discloses the core-board that a kind of plank thorn mouth chops fiber off, comprise dash board, lower dash board, middle plate, glue layer and block board, it is characterized in that: upper and lower dash board one side is distributed with the rectangle hole hole of regulation density; Block board be by the first front of whole long stuff have penetrate flaggy rectangle hole hole and side after the process of thorn mouth, then through central layer that hot cold side pressure is spliced; Middle plate is distributed with the rectangle hole hole penetrating flaggy; Glue layer is an overall glue-line.Middle plate of the present utility model, block board are processed with the rectangle hole hole penetrating flaggy, by rectangle hole hole, the few fibers on middle plate, block board are chopped off, core-board can be prevented to be out of shape; Upper and lower dash board, middle plate, block board are linked to be entirety by adhesive simultaneously, and adhesive forms overall docking simultaneously, enhances the gummed power between upper and lower dash board, middle plate, block board, can prevent from coming unstuck between core-board flaggy.
Description
Technical field
The utility model relates to a kind of core-board, and particularly a kind of plank thorn mouth chops the core-board of fiber off.
Background technology
Core-board is commonly called as lumber core, is to be formed by glue laminated Wood block floor in the middle of two panels veneer.The gross thickness of the pressure sensitive adhesive double coated allonge plate of core-board must not be less than 3mm.The corner defect of all kinds of core-board, the width within nominal breadth must not more than 5mm, and length must not be greater than 20mm.Middle plank be by the natural plank side of high-quality after heat treatment (i.e. drying chamber oven dry), be processed into the batten of certain specification, be spliced by plate joggling apparatus.Spliced plank two sides respectively covers two-layer high-quality veneer, then makes after hot and cold press glue laminated.The outermost veneer of core-board is dash board, and internal layer veneer claims middle plate, and plate sandwich layer claims block board, and the little batten of composition block board is called core bar, and the grain direction of regulation core bar is the longitudinal direction of sheet material.The Main Function of block board is for sheet material provides certain thickness and intensity, the Main Function of middle plate makes sheet material have enough transverse strengths, simultaneous buffering because of block board out-of-flatness to plate wear come harmful effect, dash board except make plate face attractive in appearance except, the longitudinal strength of sheet material can also be improved.Because core-board is special glued board, also will follow symmetry principle in production technology simultaneously, be out of shape to avoid bow warping, as a kind of heavy-gauge sheeting, core-board has the aesthetic appearance of normal thick glued board and close intensity, and core-board is lighter than thick glued board quality, but there is formaldehyde, pollution sources such as solvent and acidproof, alkali, the deficiencies such as water resistance difference.
Summary of the invention
It is not yielding that the purpose of this utility model is to provide one, the core-board that glued board flaggy not easily comes unstuck.
The technical solution adopted in the utility model is: a kind of plank thorn mouth chops the core-board of fiber off, comprises dash board, lower dash board, middle plate, glue layer and block board, it is characterized in that: upper and lower dash board one side is distributed with the rectangle hole hole of regulation density; Block board be by the first front of the whole long stuff of N/D corner have penetrate flaggy rectangle hole hole and side after the process of thorn mouth, then through central layer that hot cold side pressure is spliced into; Middle plate is distributed with the rectangle hole hole penetrating flaggy; Glue layer from upper dash board, through in plate, rectangle hole hole on block board, then to lower dash board, be an overall glue-line.
Middle plate of the present utility model, block board are processed with the rectangle hole hole penetrating flaggy, by rectangle hole hole, the few fibers on middle plate, block board are chopped off, core-board can be prevented to be out of shape; Adhesive is by infiltration simultaneously, upper and lower dash board, middle plate, block board is linked to be an entirety, enhances the gummed power between upper and lower dash board, middle plate, block board, can prevent from coming unstuck between core-board flaggy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
According to detailed description of the invention, the utility model is described in further detail below:
As can be seen from Figure 1, the utility model comprises dash board 1, lower dash board 5, middle plate 2, glue layer 4 and block board 3, it is characterized in that: upper and lower dash board one side is distributed with the rectangle hole hole of regulation density, central layer be the first front of whole long stuff of N/D corner have penetrate flaggy rectangle hole hole and side through the process of thorn mouth, be spliced into central layer through hot cold side pressure again to form, middle plate is distributed with the rectangle hole hole penetrating flaggy, glue layer is from upper dash board, rectangle hole hole in warp on plate, block board, arriving lower dash board again, is an overall glue-line.
Described rectangle hole is long is 0.5-1.5mm, and wide is 0.5-1.5mm, is spaced apart 1.0-2.5mm.
Embodiment described in the utility model is only the description carried out preferred embodiment of the present utility model; not the utility model design and scope are limited; under the prerequisite not departing from the utility model design philosophy; the various modification that in this area, engineers and technicians make the technical solution of the utility model and improvement; protection domain of the present utility model all should be fallen into; the technology contents of the utility model request protection, all records in detail in the claims.
Claims (2)
1. plank thorn mouth chops a core-board for fiber off, comprises dash board, lower dash board, middle plate, glue layer and block board, it is characterized in that: upper and lower dash board one side is distributed with the rectangle hole hole of regulation density; Block board be by the first front of whole long stuff have penetrate flaggy rectangle hole hole and side after the process of thorn mouth, then through central layer that hot cold side pressure is spliced; Middle plate is distributed with the rectangle hole hole penetrating flaggy; Glue layer from upper dash board, through in plate, rectangle hole hole on block board, then to lower dash board, be an overall glue-line.
