Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a processing machine for wood wool as a raw material for wood wool cement boards, and is particularly effective for cutting short pieces of wood wool.

(Prior technology) Wood wool cement boards, which are often used for flooring boards or wall partition boards, are made by adding cement and admixtures to the wood wool cut into ribbons from raw wood such as red pine, and then using a mixer. It was constructed by compression molding.

By the way, when processing this kind of wood wool cement board, if the pieces of wood wool are long, the entanglement between the pieces will be too strong during stirring by the mixer, making it difficult to uniformly adhere the cement glue to the pieces. First, the wood wool becomes partially dense and dense in the product, resulting in defects such as softness in areas with a high density of wood wool where there is little cement material.

On the other hand, the processing efficiency of wood wool can be increased by continuously cutting wood from logs, but the efficiency decreases significantly when small pieces are carved from logs.

(Problems to be Solved by the Invention) Therefore, it is desirable to cut the wood wool, which is carved out into ribbon-like long pieces, into short pieces of a predetermined length, preferably about 40 cm. For this purpose, it is reasonable from the point of view of processing efficiency to use a method of cutting a long wooden wool material cut out from a log in advance into a predetermined length through secondary processing.

Therefore, the purpose of the present invention is to provide a wood wool processing machine that cuts the aforementioned long wood wool cut into a ribbon shape into a predetermined length.

(Means for Solving the Problem) For this purpose, in the present invention, a cutter blade and its blade receiving member extending in the radial direction are attached to a pair of shafts rotating at high speed, and the synchronous rotation movement of these blades is attached to a pair of shafts rotating at high speed. A region is provided between each of the cutter blades and its blade receiving member, and when the cutter blades and the blade receiving member rotate, the long wood wool is rolled up and The wooden wool material is cut by a coincident abutment operation.

(Function) According to these cutter blades and their blade receiving members that rotate in synchronization, the above-mentioned winding action moves the ribbon-shaped long wood wool near the coincident abutting position on a belt conveyor or By means such as dropping with a hopper etc., the radial arrangement interval of the cutter blade and the blade receiving member, more specifically, the number of cutter blades arranged in the circumferential area and the rotation speed of these, The wood wool material can be sequentially and continuously cut into short pieces of arbitrary length, for example, about 40 cm, by high-speed processing.

In addition, the cut length of the cut wood wool is approximately constant because the length of winding between adjacent cutter blades, which depends on the rotation speed of the cutter blade and its blade receiving member, is approximately constant. You can get a homogeneous product.

(Embodiment) Next, a preferred embodiment of the processing machine of the present invention will be described.

The figure is a configuration diagram showing one embodiment of the processing machine of the present invention.
The two opposing drive shafts 1 and 2 are connected by gear coupling or the like so that they rotate at a constant speed in opposite directions (in the direction of the arrows in the figure).

Mounting boards 3, 3, .
Cutter blades 4, 4... are attached to the tips of..., respectively.

On the other hand, the other drive shaft 2 is provided with blade receiving members 5, 5, which bring the flat tips protruding in all directions to the rotation areas of the cutter blades 4, 4...
... are provided corresponding to the cutter blades 4, 4....

In other words, these cutter blades 4, 4... and their blade receiving members 5, 5..., under the synchronized rotation of their drive shafts 1 and 2, come into contact with each other at positions where they have pivoted to approximately horizontal positions. Wooden wool inserted between etc. 6
It is designed to cut.

The wood wool material 6 used in the processing machine of the present invention is cut from a raw wood as a ribbon-like long thin piece of wood, and is passed through a belt conveyor 7 to a cutting area where the cutter blade 4 and the blade support member 5 coincide. It is configured to drop into the top of the.

As a result, the wood wool 7 that is sent out in sequence is
The cutter blades 4, 4... of both drive shafts 1 and 2, which are rotating in opposite directions in the winding direction, and the blade receiver members 5, 5, are pulled down by the winding action, and are mutually held in a horizontal position. Cutting is performed by the matching cutter blade 4 and blade receiving member 5. Moreover, this operation can be performed continuously at high speed, and the cut length of the cut wood wool can be adjusted to the desired length depending on the arrangement interval of the cutter blade 4 and the blade receiving member 5 and the rotation speed thereof. For example, it can be processed uniformly to about 40 cm.

(Effects) As described above, the processing machine of the present invention is configured to cut long wood wool materials using the rotating cutter blade and its blade receiving member. The rotational drive of the parts enables high-speed and continuous processing, which improves work efficiency, and the cutting length can be reduced by drawing in the wood wool using the rolling action of the rotating blade and its receiving member. The processing machine of this invention improves work efficiency by making the cutting length uniform, and by adjusting the spacing and rotation speed of the blades and receiving members, the cutting length can be freely set. It is possible to obtain short wood hair of uniform length without deterioration,
This is the most effective method for obtaining wood wool, a raw material for wood wool cement boards.
