Embodiment Construction

[0010] The specific structure and working principle of the present invention will be further described in the following embodiments in conjunction with the accompanying drawings.

[0011] As shown in the drawings, the reverse texture planer of the present invention has a main blade 1, and a support body 4 is arranged in front of the main blade 1, and the top surface 4-1 of the support body is inclined to the front side of the main blade. 1-1, the tip of the support body is slightly lower than the cutting edge of the main blade.

[0012] The distance between the tip of the support body and the cutting edge of the main blade is L shown in FIG. 3 .

[0013] Obviously, the cross-sectional shape of the support should enable the planer of the present invention to be mounted on the cutter shaft of the planer. The most suitable cross-sectional shape of the support body is a flat sheet as shown in the drawings, that is, the support body is a support sheet. There are many other cross-...

Abstract

The invention provides an against-the-grain surfaced planning tool, which relates to a planning tool on woodworking machinery. The against-the-grain surfaced planning tool is provided with a main blade and a supporting body is arranged in front of the main blade. The top end face of the supporting body is inclined to the front side surface of the main blade and the tip of the supporting body is slightly lower than the cutting edge of the main blade. After the planning tool is arranged on a planning machine for use, the problem of timber tearing when the planning tool encounters with a reverse texture or the phenomena of timber jump or fracture when the planning tool encounters with a fag is solved or eliminate, thus greatly enhancing the planeness and smoothness of the planned surface and reaching or exceeding the planning effect of a high-speed planning machine by using an ordinary planning machine. The finish degree of timbers can exceed the polishing effect of a 100-120# accurate grinding resinder so as to avoid the grinding procedure, thus enhancing the working efficiency and utilization rate of the timber and lowering the labor intensity. The supporting body also has protective effect on the main blade, thus extending the service life of the blade and preventing human bodies from being hurt by collapsed planning tool fragments. The against-the-grain surfaced planning tool has the advantages of simple and reasonable structure and low production cost.

Description

technical field [0001] The invention provides a cutter, in particular a planer on a woodworking machine. Background technique [0002] A planer is installed on the cutter shaft of a woodworking machine such as a wood planer. This planer is flat plate, and its top end face is an inclined plane, and the top end of this inclined plane is cutting edge. In use, the front side of the blade faces the direction of rotation of the cutter shaft. As the planer rotates with the axis of the cutter, it encounters various wood grains. When the reverse grain is encountered, because the tensile strength of the transverse grain of the wood is lower than the shear strength of the cut grain, the wood chip cut by the planer will take the wood behind it along the wood grain and tear below the planed surface. It will cause pits or pockmarks on the planed surface, which will seriously affect the smoothness and smoothness of the planed surface, and sometimes cause the wood to be scrapped. Theref...
