[0002] The shaftless peeling machine is one of the equipments for producing plywood. It belongs to the shaftless mechanical transmission peeling machine. It is suitable for peeling the remaining wood core of the peeling machine into veneer. It can also be used to peel small diameter wood into veneer. The wood core is mainly driven to rotate by the roller that acts as a pressure ruler during the peeling process, and the wood core is cut by the cutter on the side of the roller. The rotation speed of the wood core is determined by the rotating driven roller.

[0003] After searching, it was found that there is an acceleration mechanism of a shaftless peeling machine and a shaftless peeling machine with publication number CN212763965U. The acceleration mechanism includes setting the lead screw nut of the feed mechanism of the shaftless peeling machine to an axially fixed and radially rotatable structure, and connecting an acceleration motor to the lead screw nut to drive the lead screw nut to rotate in the opposite direction. The acceleration structure is a single-stage acceleration mechanism, which starts slowly when the wood core to be processed is rotated, which is not conducive to improving the working efficiency. For this reason, we propose an acceleration mechanism of a shaftless peeling machine. Utility Model Content
