Clamping-shaft and non-clamping-shaft integrated rotary cutting machine for composite pressure bar

Abstract

The invention discloses a clamping-shaft and non-clamping-shaft integrated rotary cutting machine for a composite pressure bar, and belongs to the field of wood processing machines. The clamping-shaft and non-clamping-shaft integrated rotary cutting machine comprises a rack, a positioning driving system, a feeding mechanism and a rotary cutting knife assembly are arranged on the rack, and the positioning driving system comprises a roller driving mechanism and a clamping head driving mechanism; the roller driving mechanism comprises a first driving roller, a second driving roller and a composite pressure bar assembly which are distributed in a triangular-structure manner; the composite pressure bar assembly comprises a plate pressure bar and a roller pressure bar which are arranged in a spacing manner side by side; and two clamping shaft clamping assemblies with the distance capable of being longitudinally adjusted are connected to the clamping head driving mechanism. A plate pressure bar of a clamping shaft rotary cutting machine and a shaft pressure bar of a non-clamping-shaft rotary cutting machine are compounded on the clamping-shaft and non-clamping-shaft integrated rotary cutting machine to be used, the defect that remaining wooden cores need to be transferred for secondary machining through the clamping-shaft rotary cutting machine is overcome, smooth finish of veneers obtained after rotary cutting is high, uniformity is high, and the dorsal fissure is reduced by 95%.

Description

technical field [0001] The invention belongs to a kind of wood processing equipment, and in particular relates to an integrated rotary cutting machine with and without a composite pressure ruler. Background technique [0002] At present, in wood-based panel processing equipment, there are two different equipment structures for veneer processing, one is a rotary cutter with a card shaft, and the other is a rotary cutter without a card shaft. The wood of rotary cutter with clamping shaft is fixed in the center of the log through the chuck, and the pressing force is used to provide extrusion force for the rotary cutting. The action point of the extrusion force is between 5-10mm of the rotary cutting blade; The rotary cutting machine uses three friction rollers distributed in a triangular structure to drive the logs to rotate to complete the rotary cutting veneer. When the non-card shaft rotary cutting machine drives the logs to rotate, the tangent point between the three fricti...
