Abstract

(57) [Summary] [Objective] The present invention relates to a planing cylinder for a planing board, and to obtain good cutting performance even when cutting at the end of the planing cylinder. [Structure] By providing the radial fans 6 at both ends of the planer cylinder 1, the radial fan 6 also rotates by rotating the planer cylinder 1, and the radial fan 6 generates wind at the end of the planer cylinder 1 As a result, the chips generated during cutting of the material to be cut can be blown off, and the finished surface of the material to be cut can always be kept good.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a planer barrel in a planer board.

[0002]

[Prior art]

 Fig. 4 shows the wind velocity distribution of the conventional planer when the planer is rotating. The wind speed was the fastest at 10 m / sec in the center of the planer cylinder 1 and 0 m / sec at both ends.

[0003]

[Problems to be solved by the device]

 With the conventional planer cylinder, the wind speed at both ends is 0 m / sec. Therefore, when the material to be cut is cut at the ends of the planer, the chips are not discharged well, causing chip clogging, and the clogging of the chips results in the finishing of the material to be cut. There was a problem such as making the surface worse. The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, eliminate the chip clogging at the end of the planer, and always obtain good cutting performance.

[0004]

[Means for Solving the Problems]

 The above object can be achieved by providing a fan for blowing air on both sides of the planer in a planer having a plurality of planer blades on the outer circumference of the planer.

[0005]

[Action]

 By installing fans at both ends of the planer cylinder, an effective wind speed, that is, an air volume can be obtained even at the end of the planer cylinder, and it is possible to eliminate chip clogging and to maintain a good finished surface of the work material.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. 1 is a plan view showing an embodiment of the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a sectional view taken along line BB of FIG. In the figure, a knife storage groove 2 is formed in several places on the outer periphery of the planer body 1, a back blade 3 and a planer blade 4 are embedded in the tool storage groove 2, and the back blade 3 and the planer blade 4 are fixed with screws 5. . Radial fans 6 are provided at both ends of the planer body 1. In the above structure, when the rotation of the planer barrel 1 is rotated, the radial fan 6 is also rotated to generate wind at the end of the planer barrel 1. This wind blows away the chips generated during cutting of the material to be cut, so that the finished surface of the material to be cut can always be kept good.

[0007]

[Effect of device]

 According to the present invention, since the fans for blowing air are provided at both ends of the planer cylinder, the wind speed effective for discharging the chips can be obtained even at the ends of the planer cylinder, and good cutting performance can always be obtained.
