Description

Technical Field

[0001] The utility model relates to a pressure ruler strip structure of a rotary cutting machine. Background Art

[0002] The rotary cutter is used to process wood segments of a certain length and diameter into continuous veneer strips (wood sheets) for the production of plywood, joinery boards and other artificial board veneers. The thickness of the wood sheets cut by the existing rotary cutter is determined by the distance between the pressure strip and the cutter. The existing non-carded rotary cutters on the market do not have pressure strips, while the carded rotary cutters have fixed pressure strips without pressure rollers. Since the non-carded rotary cutter has a pressure roller and must ensure that the peeled wood core is small enough, the pressure strip can only be designed in a strip shape. However, due to processing problems or long-term use, so many single pressure strips will have different degrees of deformation, resulting in the inability to ensure straightness (all pressure strips are on the same straight line). Utility Model Content

[0003] The utility model aims to provide a pressure ruler strip structure of a rotary cutting machine, wherein the pressure ruler strip is helpful to realize the position adjustment of the pressure ruler strip.

[0004] The technical solution of the utility model is: a pressure ruler strip structure of a peeling machine, comprising a peeling machine frame, on which a plurality of vertically arranged pressure ruler strips are sequentially installed in a horizontal direction, a positioning convex strip is horizontally arranged on the peeling machine frame, a positioning groove matched with the positioning convex strip is arranged on the upper rear side of the pressure ruler strip, a first bolt and a second bolt screwed with the peeling machine frame are longitudinally penetrated correspondingly at the upper and lower sides of the positioning groove on the pressure ruler strip, and an adjusting bolt abutting against the peeling machine frame is longitudinally screwed at the lower side of the second bolt.

[0005] Furthermore, the lower parts of the second pressure ruler strip on the left and the second pressure ruler strip on the right are both equipped with trimming blades, and the lower parts of the remaining pressure ruler strips are all equipped with wear-resistant blocks.

[0006] Furthermore, the lower parts of the second pressure ruler bar on the left and the second pressure ruler bar on the right are both provided with longitudinal slots, and vertical slits are provided longitudinally penetrating the pressure ruler bar through the longitudinal slots. The trimming blade is arranged in the longitudinal slots and is clamped by a locking bolt which transversely passes through the vertical slit and screws the trimming blade to the pressure ruler bar.

[0007] Furthermore, transverse through grooves are provided at the lower part of the remaining pressure bars and on the side facing the cutter, and transverse gaps are longitudinally provided on the rear side walls of the transverse through grooves. The wear-resistant blocks are arranged in the transverse through grooves and are clamped by locking bolts that vertically pass through the transverse gaps and are screwed to the pressure bars.

[0008] Furthermore, the rear side of the pressure ruler strip has a material-cutting portion.

[0009] Furthermore, a driving roller is laterally installed on the peeling machine frame at the rear side of the pressure bar, an inclined cutter is laterally installed at the front lower part of the driving roller, and a gap is provided between the lower parts of two adjacent pressure bars for the pressure plate assembly on the driving roller to be exposed.

[0010] Furthermore, the pressure plate assembly includes a disc-shaped pressure roller, and a toothed plate is fitted on one side of the disc-shaped pressure roller, and the protruding teeth of the toothed plate protrude from the circumferential surface of the disc-shaped pressure roller.

[0011] Compared with the prior art, the utility model has the following advantages: the pressure bar helps to adjust the position of the pressure bar, and then adjust the straightness of all the pressure bars. At the same time, the wear-resistant block is arranged at the lower part of the pressure bar, which helps to increase the service life of the pressure bar. In addition, the cutting blades are arranged on the second pressure bar on the left and right sides to help realize the side cutting of the wooden board sheet after rotary cutting.

[0023] In this embodiment, in order to achieve the distance between a single pressure bar and the cutter, the adjustment mechanism includes a positioning convex strip 11 disposed transversely on the frame of the peeling machine, a positioning groove 42 matching the positioning convex strip is disposed on the upper rear side of the pressure bar, and a first bolt 50 and a second bolt 60 threadedly connected to the frame of the peeling machine are longitudinally penetrated on the upper and lower sides of the positioning groove on the pressure bar, and an adjustment bolt 70 abutting against the frame of the peeling machine is longitudinally threadedly connected to the lower side of the second bolt. Thus, by adjusting the connection depth between the first bolt, the second bolt and the frame of the peeling machine, and then rotating the adjustment bolt to adjust the offset of the elastic deformation of the lower part of the pressure bar, the distance between the pressure bar and the cutter can be adjusted, and finally the first bolt and the second bolt are locked.

[0024] In this embodiment, in order to better adjust the pressure bar, the rear side of the pressure bar has a material-cutting portion 43, which is located in the area between the second bolt and the adjusting bolt, thereby weakening the local strength of the pressure bar and helping the adjusting bolt to better adjust the distance between the lower part of the pressure bar and the cutter.

[0025] In this embodiment, in order to be able to cut off the excess part of the side of the wooden board sheet when peeling the wood, the lower parts of the second pressure strip on the left and the second pressure strip on the right are both installed with longitudinally arranged trimming blades 80, and the lower parts of the remaining pressure strips are all installed with wear-resistant blocks 90.
