Veneer rolling and softening device

Abstract

The invention discloses a veneer rolling and softening device which comprises a veneer lathe rotary cutter and a pressure bar. The veneer lathe rotary cutter and the pressure bar are arranged at the lower left end of a log. The veneer lathe rotary cutter is movably connected with a small squeeze roller through veneer. The small squeeze roller is movably connected with a large squeeze roller through the veneer. The large squeeze roller is fixedly connected with a pressure device and further fixedly connected with a driving device. The driving device is fixedly connected with a contact wheel. The contact wheel is movably connected with the log. According to the veneer rolling and softening device, in the rotary cutting process of the veneer, cracks are generated in the veneer so that stress can be eliminated, and the veneer becomes soft and flat. The yield of the veneer is increased, and the uneven cutting phenomenon caused by curling of non-softened veneer can be avoided. In the splicing process, the phenomenon that veneer edge warping is caused by curling, and accordingly bonding of splicing seams is bad is avoided. In the gluing process, plywood deformation caused by uneven internal stress is avoided.

Description

technical field [0001] The invention relates to a plate processing equipment, in particular to a veneer rolling softening device. Background technique [0002] At present, the veneers produced by ordinary rotary cutting have the following problems: ①Due to the different lengths of the circumference observed from the end face of the wood section during rotary cutting, the areas of the two sides of the veneer after rotary cutting are different, that is, the areas of the two sides of the veneer are asymmetrical , thus causing warpage of the veneer; the greater the thickness of the veneer, the more serious this situation will be. ② During the process of veneer spinning by the rotary cutter, a large number of small cracks are generated along the direction of fiber arrangement on the surface of the veneer in contact with the rotary knife, that is, the shape and structure of the two sides of the veneer are also asymmetrical, resulting in single The warpage of the board; similarly,...
