Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt replacement structure for a wood cutting saw,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a belt exchange structure for a woodcutting saw, and more particularly, The present invention relates to a belt exchange structure of a saw for cutting.

Wood is the most abundant and longest used material in human history. Today, it is used in various fields such as architecture and furniture, and the building made of reinforced concrete is also used as interior material including doors.

These timber are processed in the form of plate or wood from the sawmill in the case of logs, and in the case of synthetic wood, most of them are produced in the form of plates and sent to the factory for secondary production. Goods.

The cutting device mainly has a structure in which a part of a disk-shaped cutting saw rotating on the work table is protruded on the upper surface, and has a structure in which the wood is cut along the upper surface of the work table while passing through the saw .

At this time, the rotation of the cutting saw is made of a motor, which is a relatively loose material, but resistance is generated in the cutting process, so that the driving force of the motor is transmitted to the belt without using gears or timing belts.

However, the belt may be broken or worn during use, so it may be necessary to replace it in the middle and loose during operation. However, in order to replace the belt, Exposed to the belt pulleys are working at considerable force and are exposed to the risk of getting stuck during work.

SUMMARY OF THE INVENTION The present invention has been developed in order to solve the above-mentioned problems, and it is an object of the present invention to provide a belt driving device capable of easily adjusting the tension of a belt, And to develop a spit replacement structure for a cutting saw for woodworking.

According to an aspect of the present invention, there is provided an apparatus for cutting a wood material, comprising: a driving belt pulley rotated by a driving motor at one side of a work table; And a belt for interlocking the driving belt pulley and the driven belt pulley;

A lower panel on which the driving motor and the driving belt pulley are mounted;

A plurality of guide bars vertically installed on the lower panel and extending upward;

An upper panel mounted on the guide bar to mount the cutting saw and the driven belt pulley;

A lower portion of which is rotatably mounted on a fixing member mounted on the lower panel, an upper portion of which is engaged with a nut member mounted on the upper panel and rotates, a tool is inserted into the upper surface of the nut member, And a screw shaft for moving up and down the upper panel by forming a tool groove for rotating the upper panel;
The distance between the driving belt pulley and the driven belt pulley mounted on the shaft of the driving motor when the upper panel is lowered by selectively rotating the screw shaft is mounted on the upper panel so that the driven belt pulley mounted on the shaft of the cutting saw is moved up and down And the belt is removed or fitted so that the belt is replaced.

As described above, according to the present invention, a driven belt pulley mounted on a shaft of a cutting saw is mounted on an upper panel mounted to move up and down. When the upper panel is lowered by rotating the screw shaft if necessary, The distance between the pulley and the driven belt pulley is narrowed so that the belt can be easily removed and mounted, thereby facilitating the replacement work of the belt.

Figure 1 is a perspective view of an embodiment of the present invention.
2 is a conceptual diagram according to an embodiment of the present invention.
3 is a conceptual diagram illustrating a state in which the upper panel is lowered according to an embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of an embodiment of the present invention, FIG. 2 is a conceptual diagram according to an embodiment of the present invention, FIG. 3 is a conceptual diagram illustrating a state in which an upper panel according to an embodiment of the present invention is lowered, The present invention relates to a cutting machine comprising a drive belt pulley 12 which is rotated by a drive motor 11 at one side of a work table 1 and a disk-shaped cut saw 13 which partly projects from the top surface of the work table 1, And a belt 15 for interlocking the drive belt pulley 12 and the driven belt pulley 14 in a generally used wood cutting device in which a belt (not shown) 15) or to adjust the tension easily.

A lower panel 21 on which the driving motor 11 and the driving belt pulley 12 are mounted;

A plurality of guide bars 22 vertically installed on the lower panel 21 and extending upward;

An upper panel 23 mounted on the guide bar 22 to be raised and lowered and on which the cutting saw 13 and the driven belt pulley 14 are mounted;

And a lower end thereof is rotatably mounted on a fixing member 241 mounted on the lower panel 21 and an upper portion of the nut member 242 mounted on the upper panel 23, And a screw shaft (24) formed on the upper surface thereof for forming a tool groove (243) for rotating the tool by inserting the tool to move up and down the upper panel (23) The structure of belt replacement of the cutting saw is shown.

In such a configuration, when the bolt 15 needs to be replaced, the tool is inserted into the tool groove 243 and the screw shaft 24 is rotated, so that the nut member 242 coupled with the rotation of the screw shaft 24 is lowered The belt 15 is loosened as shown in Fig.

When the belt (15) is loosely changed, it is possible to easily replace the bag (15). In the case of replacing the belt (15) in a pulled state, It is possible to solve the problem that there are many cases where the device is cut and cut.

In this case, the configuration of the present invention is not limited to the replacement of the belt 15, but may be a period of time during which the tension of the belt 15 can be adjusted when the tension of the belt 15 is excessively large or loose.

The easy replacement of the belt 15 of the present invention is achieved by mounting the driven belt pulley 14 mounted on the shaft of the cutting saw 13 to the upper panel 23 so as to move up and down, When the upper panel 23 is lowered, the distance between the driving belt pulley 12 and the driven belt pulley 14 mounted on the shaft of the driving motor 11 is narrowed and the belt 15 is removed or mounted, 15 is replaced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. I will understand. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
