[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 1 —5, an automatic side unloading device for a four-sided saw, including a conveyor belt 1, the conveyor belt 1 including a frame 11 and a conveyor roller 12, and also including an air blowing unit 2 and a unloading baffle 3. The air blowing unit 2 is disposed on the inner side wall of the frame 11, and the unloading baffle 3 is disposed on the outer side wall of the frame 11. The waste material on the conveyor roller 12 is moved to both sides by the air blowing unit 2 and unloaded by the unloading baffle 3.

[0025] Specifically, the conveyor belt 1 is a conventional conveying device in the prior art, including a frame 11 and several conveyor rollers 12. These rollers are arranged in a linear array on the frame 11. A transmission mechanism is installed within the frame 11, maintaining a transmission connection with the several conveyor rollers 12. The transmission mechanism can drive the several conveyor rollers 12 to rotate, thereby achieving the function of conveying materials. It should be noted that the specific structure and driving principle of the transmission mechanism are conventional technologies and will not be elaborated upon here.

[0026] As an embodiment of the present invention, a connecting roller 15 is rotatably connected to the frame 11. The connecting roller 15 is set on the frame 11 close to the material conveying direction, which can support the material and provide guidance for the material, so that the material moves more smoothly from the four-sided saw to the conveyor belt 1.

[0027] It should be noted that the connecting roller 15 can be connected to the transmission mechanism on the frame 11 to ensure that the material can be conveyed.

[0028] As an embodiment of the present invention, an air blowing unit 2 is provided inside the frame 11. Specifically, there are several air blowing units 2, which are symmetrically distributed inside the frame 11. Specifically, the air blowing units 2 on one side inside the frame 11 are arranged in a linear array. A discharge baffle 3 is fixedly installed on the outer wall of the frame 11 along its length.

[0029] During use, the board and waste material cut by the four-sided saw are conveyed by the conveyor roller 12. Due to the cutting, there is a certain gap between the waste material and the board. The air blowing unit 2 blows air into the gap between the waste material and the board, causing the waste material to move to the side of the frame 11. When the waste material moves to the discharge baffle 3, the discharge baffle 3 further guides the waste material and discharges it, realizing the automatic separation of waste material and board material.

[0030] This utility model uses an air blowing unit 2 to blow the waste material on the conveyor roller 12 of the conveyor belt 1 to both sides, and then guides the waste material further through the discharge baffle 3 to the outside of the frame 11, thereby realizing automatic waste material discharge, reducing manual input and lowering labor costs.

[0031] As an embodiment of this utility model, the air blowing unit 2 includes a mounting base 21, a rotating baffle 22, and a nozzle 23. Specifically, the mounting base 21 has a "T"-shaped structure, and the bottom of the mounting base 21 is fixedly mounted to the inner wall of the frame 11 by bolts. An arc-shaped groove 24 is provided on the outer wall of the mounting base 21. The rotating baffle 22 has an "L"-shaped structure, and a connecting groove 25 is provided on the outer wall of the "L"-shaped side of the rotating baffle 22. A connecting bolt 26 is slidably connected inside the arc-shaped groove 24. The connecting groove 25 on the rotating baffle 22 is connected to... The connecting bolt 26 connects the mounting base 21 and the rotating baffle 22, allowing for quick adjustment of the mounting position and angle of the rotating baffle 22 on the mounting base 21. When it is necessary to adjust the mounting position and angle of the rotating baffle 22, simply loosen the connecting bolt 26 to keep the rotating baffle 22 in a movable connection with the mounting base 21. At this time, the position and angle of the rotating baffle 22 on the arc-shaped groove 24 can be adjusted. After adjustment, tighten the connecting bolt 26 to keep the rotating baffle 22 and the mounting base 21 secure.

[0032] A connection hole is provided on one side of the outer wall of the rotating baffle 22 with an "L" shape. The nozzle 23 is fixedly installed in the connection hole. The nozzle 23 can be connected to an external air pump to ensure sufficient air pressure to blow the waste to both sides.

[0033] As a further embodiment provided by this utility model, such as Figure 5As shown, the discharge baffle 3 includes a straight portion 31 and an inclined portion 32. Specifically, the straight portion 31 is connected to the inclined portion 32, and the straight portion 31 and the inclined portion 32 are distributed at a certain angle. Preferably, the angle between the straight portion 31 and the inclined portion 32 is acute, so that the waste material located on the inclined portion 32 can move along the top of the inclined portion 32 under the action of gravity, causing the waste material to fall off the inclined portion 32 automatically. The waste material can be collected by a dedicated collection frame outside the frame 11. The wall is provided with a mounting groove 14, and a fastening screw is connected to the outer wall of the straight part 31. The straight part 31 is connected to the mounting groove 14 by the fastening screw. The connection between the fastening screw and the mounting groove 14 allows the installation position of the discharge baffle 3 on the frame 11 to be adjusted for actual production. The inclined part 32 is provided with a discharge side 33. Specifically, the discharge side 33 is inclined, that is, the inclined part 32 has a trapezoidal or triangular structure on the plane, which facilitates the discharge of waste material.

[0034] Working principle:

[0035] After the four-sided saw cuts the board, waste material is left on both sides of the board. The waste material is completely separated from the board, but at this time the waste material and the board are in a close fit. Under the conveying action of the four-sided saw, the board and waste material are conveyed towards the conveyor belt 1.

[0036] As the sheet metal and waste material move on the conveyor roller 12, the air blowing unit 2 blows air outward through the air pump. When the sheet metal and waste material move to the vicinity of the air blowing unit 2, the air blown out by the air blowing unit 2 blows out between the sheet metal and waste material and pushes the waste material to both sides, pushing the waste material onto the discharge baffle 3.

[0037] After the waste material moves onto the discharge baffle 3, it is further guided by the inclined part 32 with a slanted cutting angle to discharge the waste material.

[0038] Those skilled in the art will understand that other similar connection methods can also achieve this utility model. For example, welding, bonding, or screwing.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
