Description

A wood rotary cutting machine without card shaft

technical field

The invention relates to the technical field of wood processing equipment, in particular to a shaft-free wood rotary cutter.

Background technique

In order to achieve a good decorative effect, the surface of the decorative panel is required to be smooth, flat and free of burrs. Usually it is necessary to use wood with a larger diameter for processing to achieve the above requirements. Adopt larger wood to process this kind of decorative panel usually using card shaft wood rotary cutting machine to process, after the wood processing by card shaft wood rotary cutting machine, there will be remaining wood with a diameter of 2-3cm. The diameter of the remaining timber is relatively large, the waste is serious, and the utilization rate of timber is low.

The non-card shaft wood rotary cutter is mainly used for wood processing with a small diameter, which can improve the utilization rate of wood. The existing card-free rotary cutting machine is mainly composed of a frame, a driving double roller, a cloth roller, a knife holder, a transmission system, an electrical system, etc.; the cloth roller and the driving double roller rotate at the same diameter and at the same speed to drive the wood to rotate; The fabric roller and the rotary cutter are fixedly installed on the knife bed, and move horizontally through the feed screw; in order that the three rollers can always exert pressure on the wood, realize the rotation of the wood core and be able to rotary cut, the center point of the fabric roller is installed on the driving double roller Above the vertical bisector of the center, the edge of the rotary cutting knife is installed below.

The prior art shaftless wood rotary cutter is shown in Figure 1. Figure 1 is a geometric analysis diagram of the selection and mechanism of the non-card shaft wood rotary cutter for peeling 1.5mm thick veneer. The cutting thickness is 0.6mm, which is far from 1.5mm. The actual diameter of the wood is 0.9mm larger than the theoretical wood diameter per revolution, and the propulsion screw advances 1.5mm per revolution of the wood (according to the thickness measurement, the actual screw advance amount: 2*1.5 + Wood moves to the drive roller), the pressure of wood is getting bigger and bigger, and deformation occurs. When the extrusion deformation reaches the gap between the distribution roller and the rotary cutter (knife door width), the thickness of the board will normally reach 1.5mm. As the wood becomes smaller, the natural cutting volume of the rotary cutter increases, and the pressure slowly decreases. The large-diameter wood-end veneer of the veneer cut in this way is severely squeezed, and the thickness of the veneer is uneven, with pressure roller texture (indentation) on the surface, and the wood structure is seriously damaged, so it cannot be used as a surface veneer.

Therefore, in view of the existing problems in the prior art, it is particularly important to provide a technology of a shaft-free wood rotary cutter capable of producing a rotary-cut veneer with high flatness, smooth surface and no burrs.

The cutting angle gradually decreases, that is, it gradually changes from greater than 90° to less than 90°, and the best cutting angle can always be maintained. Make the first driving roller 11, the second driving roller 12 and the cloth plate roller always tangent to the wood, no need to squeeze the wood, can effectively reduce the extrusion force on the wood, and effectively eliminate the surface indentation of the veneer after rotary cutting , which reduces the damage to the veneer wood structure, can be used as a decorative panel, and reduces the rotation and propulsion power of the drive motor, saving energy and cost.
