Background technology
Glued board is to be peeled into veneer or to be become veneer by the flitch slicing by juggle, sticks with glue three layers or the board-like material of multilayer that the agent gummed forms again, uses the odd-level veneer usually, and the orthogonal gummed of machine direction of adjacent layer veneer is formed.
Chinese patent CN1054556A discloses the carpenter that a kind of slicer is cut thick sheet, comprise sheet by the feeding belt pressurization and deliver to the workbench surface, the feeding belt that drives is placed on the unloading face that comprises the work cutter and contacts relatively and with the terminal of blade, be fixed on the clamp on the blade, identical with the sheet thickness that cuts out in unloading face and the space between the clamp of cutter.
In carpenter's slicer of cutting thick sheet in the above-mentioned patent documentation, the height of blade and cutter passes through fixedly aftertable, and move up and down front console adjustment, that is to say, when the thickness of the glued board of needs is big, just front console moves down to increase the gap between blade and the cutter, but after blade moves down, when being placed on for the production of the timber of glued board that on the workbench fit with aftertable in the back, might can not well fit because front console moves down too much with front console, even it is gapped before timber and the front console, thereby the glued board of producing can not meet the requirements of thickness, and the deformation rate difference of every block of timber, the thickness between the glued board of producing in these cases will be different, and then influence the uniformity of glued board.
In addition, carpenter's slicer of cutting thick sheet in the above-mentioned patent documentation is to realize the operation of workbench by manual operation, and manually operated precision is often relevant with operator's experience and state, different operators and the same operator situation to the operation of workbench under different conditions is all inequality, causes the thickness inconsequent between the glued board of production easily.
