Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for producing wood wool, particularly wood wool cement, which is used as a material for various constructions, in which wood wool is mixed with cement.

Wood wool cement has recently been widely used as a building material because it has backward characteristics such as back absorption, heat resistance, and fire resistance, and is light and easy to work with. The wood wool mixed in hair cement is usually 10 to 30 pieces long and 0.5 to 3 nLIR thick in order to exhibit the above characteristics.
Moderate is preferred.

Now, to make this length of wool from raw wood, the raw wood is 10~
30 (M-width (=cut rMr) and cut in the longitudinal direction,
It is troublesome to cut one piece of real wood into pieces with a width of 10 to 30 pots, and the process of carving out wood from such a narrow raw material is also time consuming and troublesome.

Therefore, the purpose of this invention is to cut 1 native tree at 20 to 601 cm, which is a relatively simple answer to cutting 1!4 rT. Ⅱ-lL'ii in the drink
Although the present invention uses abrasive material, it provides a device that efficiently cuts wood wool having a width of 10 to 30 ts.

That is, each of the cutter blades is comprised of a pair of cutting blade groups, a mechanism for reciprocating the cutting blade groups, and a mechanism for pressing the one-piece wood material in the direction of these cutting blade groups. Therefore, by reciprocating a large number of groups of cutting blades and horizontally cutting raw wood material to a predetermined thickness, a large number of wood wool can be easily produced. However, this results in the production of 20 to 60 pieces of wool.

The present invention relates to a cutting operation of raw wood material, in which one group of cutting blades on the forward path enters a part of the raw wood material from a slightly opposite direction from approximately the center of the raw wood material and performs cutting. 'i'
The other cutting blade of R cuts a part of the remaining ice phase on the same line along the locus of the one cutting blade group. ,
) can be produced simultaneously. In other words, the feature of the present invention lies in the efficient production of Ph'J outside size wood wool, even though it uses J wood material that is twice as long as the desired size.

The present invention will be specifically explained below using the drawings.

1.1' is a group of one to several vertical rolls facing each other with a constant interval between them, and is pivotally supported on the frame 2 of the device 6. Between this group of rolls 1'M is 2 of the length of the wood to be cut.
A raw wood material 3 with a length equal to twice the length is clamped. Binion gears 4 and 4' are disposed coaxially with each of the roll groups 1 and 1', and each of them is connected to a worm 17 of the horizontal shaft 5.
, 17'. Horizontal! 1iIII 5 is supported by the device frame 2, and one end thereof is connected to a drive source 6 that rotates the horizontal shaft 5 intermittently via a speed reduction device (not shown).

Reference numeral 7.7' denotes horizontal rails mounted vertically opposite to each other in the apparatus frame 2, and a reciprocating plate 9 having a window 8 formed approximately in the center thereof is slidably fitted therein. This love 8 has a pair of blades 1 on the left and right.
The inner direction of each of 0 and 11 is fixed at position i6, and the outer part of each is fixed at reciprocating movement &9. The blades 10 and 11 located in the window 8 form a large number of equally spaced horizontal cutting blade groups 12 and 1.9 facing each other with a suitable gap between them, and the blade groups 12 and 13. is provided at a position in contact with the Uero Cj true ice phase material 3.

One end of the crank 1I1114 is pivotally attached to one end of the reciprocating plate 9, and the other end of the crankshaft 14 is attached to the outside of a crank disk 16 to which rotation is transmitted via a suitable drive source and reduction gear 15.

Now, if you want to efficiently manufacture a large number of wood wool of about 20 lengths, you can simply cut the raw wood into 40 lengths, which is relatively easy to cut. A large number of IP wood materials 3 having this length are placed 1d between the roll groups 1° 1' with the same walking force. During work, this one prefecture wood material 3 is driven by a drive source 6,
Rotation +1II5, Worm 17.17', Binion 4,
4' is transmitted to the rolls 1, 1', so that both sides of the rolls 1, 1' are stretched and sent out in the direction of the cutting blade groups 12, 13! However, the structure is such that the sending is performed intermittently by known means, as will be described later.

The process of cutting wood wool from 1 wood material 3 is shown in Figure 3 tar.
, fbl. The tip of one cutting blade group 12, which is currently attached to the reciprocating plate 9, is positioned slightly to the left of the center line A of the log. Here, when the sliding force is transmitted to the reciprocating plate 9 via the drive source, deceleration device 15, crank disk 16, and crankshaft 14, the cutting blade group 12 penetrates a part of the log material 3 by about 1 to 3 guR. Then, the portion indicated by cross-hunting in FIG. 3 is cut. The wood wool obtained by applying the force λ is approximately half the length of the raw wood material 3 by about 10 degrees.

At this time, the feeding of the raw wood material by the roll groups 1 and 1' is stopped, and the reciprocating plate 9 slides in the forward direction due to the rotation of the crank disk 16 in the interval 1.

Therefore, the tip of the cutting blade group 13 on the other temporary path is as shown in FIG.
It enters into the material 3 from a little to the right of the center tM A of the raw wood material 3, as shown in FIG. 1, and cuts the same length of wood hair as before. 1- In other words, normally, when cutting two pieces of wool from the center of one log to the left and right, a chevron-shaped residual part will be created near the center of one log, and one end of the wood will be bent or deflected and will be damaged. 4+ia, but in the case of the present invention, when cutting with the pair of cutters 11 + blade groups 12 and 13, the approximately central part of the log is cut with both cutting blades, so such a There is no such thing.

Normally, the cutting blade groups 12 and 13 are constructed as shown in FIG. 4. That is, as described above, each cutting blade group 12, 13
18. is a multi-shell cutting blade with the same width as the wood wool to be manufactured.
18..., the width of the wood wool is the same, and the width spacing is 19.1

Each blade is located in the song of Ill,
The same spacing between 1B... and 18', 1B'... is the same as the thickness of the wood wool. By doing this, the forward moving plate 9
With the reciprocating motion, you can easily make two or more desired pieces of wool.
