[0015] As cylinder one moves toward the middle of plate two, cylinder one separates from the L-plate, and then the elasticity of spring three drives the blocking portion to move to the connection between tube two and tube three to block tube two. When the piston shaft moves toward spring one in the inner cavity of cylinder one, the air in the inner cavity of cylinder one is pushed toward tube one, and this air then enters the inner cavity of cylinder two through the telescopic tube, under the piston plate; thereby pushing the piston plate upward, and then the elasticity of spring two generates resistance, driving the piston plate to compress the air in the inner cavity of cylinder two.

[0016] Then the circular sawing part is started to rotate and the aluminum profile on the plate 2 is sawed. After the sawing is completed, the bidirectional screw drives the moving part 1 to reset, so that the tube 1 moves toward the L plate and resets. When the tube 1 contacts the L plate, it pushes the L plate to move, thereby pulling the blocking part away from the connection between the tube 2 and the tube 3, so that the compressed air in the inner cavity of the tube 2 is ejected from the air jet part through the tube 2 to the cutting part of the aluminum profile, thereby blowing away the metal debris at the cutting part to prevent the metal debris on the surface of the plate 2 from affecting the hygiene of the working environment.

[0021] The driving assembly includes a motor 2, a bidirectional lead screw 3, a moving part 4, a rod 5 and a plate 6; Motor 1-2 is mounted on plate 2-26, and its output shaft is connected to bidirectional screw 3. The thread on bidirectional screw 3 is matched with moving part 1-4. Moving part 1-4 is movably sleeved on rod 1-5. Rod 1-5 is mounted in support body 1; plate 1-6 is mounted on moving part 1-4; and a piston assembly is installed in plate 1-6.

[0022] Starting motor 12 drives bidirectional screw 3 to rotate, thereby driving moving part 14 to move along the axis of bidirectional screw 3 and rod 15, and then moving part 14 drives plate 16 to move toward the middle of plate 26, thereby driving cylinder 17 to move.

[0023] The piston assembly includes a cylinder 7, a tube 11 and a one-way air inlet valve 12; Cylinder 17 is installed at the movable end of the drive assembly; tube 11 is connected to cylinder 17; a one-way air intake valve 12 is installed on cylinder 17; a clamping assembly is installed in cylinder 17; a telescopic tube 14 is connected to tube 11; the clamping assembly moves in cylinder 17, drawing air into cylinder 17 from the one-way air intake valve 12, or exhausting the air in cylinder 7 from the telescopic tube 14.

[0024] When cylinder 17 moves toward the aluminum profile, cylinder 17 drives the clamping plate 10 to squeeze the aluminum profile, thereby driving the piston shaft 9 to move toward the spring 18 in the inner cavity of cylinder 17, and pushing the air in the inner cavity of cylinder 17 along the tube 11; when cylinder 17 moves away from the aluminum profile, the clamping plate 10 gradually separates from the surface of the aluminum profile, and then the elasticity of the spring 8 drives the piston shaft 9 to move toward the clamping plate 10. At this time, the external air is drawn into the inner cavity of cylinder 17 through the one-way air intake valve 12 through the piston shaft 9 for temporary storage.

[0025] like Figure 2 As shown, the clamping plate 10 is located on the front and rear sides above the second plate 26. When the aluminum profile needs to be sawed, the aluminum profile is placed on the second plate 26 from the left and right sides of the second plate 26. The two sides of the aluminum profile and the two ends of the aluminum profile mentioned in this application respectively refer to: the two sides of the aluminum profile are the two sides facing the clamping plate 10; and the two ends of the aluminum profile are the two ends close to the left and right sides of the second plate 26.

[0026] The clamping assembly includes a spring 8, a piston shaft 9 and a clamping plate 10; The two ends of spring 18 are respectively connected to the large end of piston shaft 9 and cylinder 17; the small end of piston shaft 9 passes through cylinder 17 and is connected to clamping plate 10; cylinder 17 drives clamping plate 10 to move and clamp the aluminum profile.

[0027] Cylinder 17 drives the clamping plates 10 toward both sides of the aluminum profile. The clamping plates 10 in contact with both sides of the aluminum profile are pushed in the direction of spring 18, while the clamping plates 10 in contact with both ends of the aluminum profile contact both ends of the aluminum profile, thereby clamping and limiting both sides and both ends of the aluminum profile through multiple clamping plates 10.

[0028] Example 2, as Figure 1 、 Figure 2 、 Figure 4-Figure 7 As shown, the aluminum profile sawing device proposed by the present invention, compared with the first embodiment, the soot blowing mechanism of this embodiment includes a second cylinder 15, a second spring 16, a piston plate 17, a guide rod 18, a control assembly and a collection assembly; Cylinder 2 15 is connected to the telescopic tube 14 , the two ends of spring 2 16 are respectively connected to cylinder 2 15 and piston plate 17 , and the guide rod 18 passes through cylinder 2 15 and is connected to the piston plate 17 ; the control component is connected to cylinder 2 15 ; the collecting component is installed at the bottom inside the support body 1 ; the connection point between the telescopic tube 14 and cylinder 2 15 is located below the piston plate 17 .

[0029] The air entering the inner cavity of the second cylinder 15 from the telescopic tube 14 enters the lower portion of the piston plate 17 in the inner cavity of the second cylinder 15 . At this time, the elasticity of the second spring 16 drives the piston plate 17 to compress the entering air.

[0030] Control assembly pipe 2 19, jet portion 20, cylinder 3 21, spring 3 22, blocking portion 23, rod 24 and L-plate 25; The two ends of tube 2 19 are respectively connected to cylinder 2 15 and jet portion 20; cylinder 3 21 is installed on tube 2 19; the two ends of spring 3 22 are respectively connected to cylinder 3 21 and blocking portion 23; blocking portion 23 is connected to rod 2 24; rod 24 passes through cylinder 3 21 and is connected to L-plate 25; in the initial state, L-plate 25 is pushed by the piston assembly, and L-plate 25 pulls blocking portion 23 toward spring 3 22 through rod 2 24.

[0031] In the initial state, the L-plate 25 is pulled by the tube 1 7, and the tube 2 19, the air injection portion 20 and the tube 3 21 are connected; when the tube 1 7 moves toward the plate 2 26, the L-plate 25 loses the push limit of the tube 1 7, and the elasticity of the spring 3 22 drives the blocking portion 23 to move toward the connection between the tube 2 19 and the tube 3 21, thereby blocking the connection between the tube 2 19 and the tube 3 21, so that the air in the inner cavity of the tube 2 15 cannot be discharged from the tube 2 19.

[0032] The collection assembly includes an inclined plate 27, a mounting frame 28 and a collection box 29; The inclined plate 27 is mounted on the inner side of the support body 1 ; the mounting frame 28 is mounted on the bottom of the inclined plate 27 ; the collecting box 29 is plugged into the mounting frame 28 ; the inclined plate 27 is located below the air jet portion 20 .

[0033] The blown debris falls into the inclined plate 27, and then enters the collection box 29 along the inclined plate 27, and is collected in the collection box 29. After a large amount of debris is collected in the collection box 29, the collection box 29 can be pulled out from the inner cavity of the installation frame 28.

[0034] Example 3, as Figure 6-8As shown, the aluminum profile sawing device proposed by the present invention, compared with the second embodiment, the sawing mechanism of this embodiment includes a movable component, a mounting frame 35, a third motor 36, a first transmission wheel 37, a second transmission wheel 38 and a sawing part 39; The movable component is installed in the support body 1, and the mounting frame 35 is installed on the movable end of the movable component; the motor three 36 is installed outside the mounting frame 35, the output shaft of the motor three 36 is connected to the transmission wheel one 37, the transmission wheel two 38 is installed in the mounting frame 35, and the transmission wheel two 38 is connected to the sawing part 39; the transmission wheel one 37 and the transmission wheel two 38 are connected in transmission.

[0035] The movable assembly includes a support frame 30, a second motor 31, a driving screw 32, a second moving part 33, a third rod 34 and a tapered part. 40; The support frame 30 is mounted within the support body 1 , and the second motor 31 is mounted on the support frame 30 . The output shaft of the support frame 30 is connected to a drive screw 32 ; the drive screw 32 is threadedly engaged with the second moving portion 33 ; the second moving portion 33 is movably sleeved on a third rod 34 , which is mounted within the support frame 30 . The tapered portion 40 is mounted on the second moving portion 33 and is located below the air injection portion 20 ; and the mounting bracket 35 is mounted on the second moving portion 33 .

[0036] When the second moving part 33 is reset, it drives the conical part 40 to move to the bottom of the air-jet part 20. The debris that falls is then guided by the conical part 40 and scattered into the inclined plate 27. Then, it enters the collection box 29 in the inner cavity of the mounting frame 28 and is collected by the collection box 29.

[0037] A rectangular hole is provided in the middle of the plate 26, and the air ejected from the air jet part 20 blows on the sawing part of the aluminum profile, thereby blowing the metal debris at the cutting part from the rectangular hole into the inclined plate 27; two movable grooves are provided on the plate 26, and the connection between the movable part 14 and the plate 16 is slidably connected in the movable groove; two rectangular grooves are provided above the support body 1, and the rectangular grooves are located on the moving path of the one-way air outlet valve 13. When the cylinder 17 moves toward the direction of the aluminum profile, the one-way air outlet valve 13 can move in the rectangular groove, thereby avoiding the one-way air outlet valve 13 being blocked during the movement process.

[0038] In summary, in the present invention, the aluminum profile is placed on plate 2 26, and the portion of the aluminum profile that needs to be sawed is located in the middle of plate 2 26. Then, motor 1 2 is started to drive the bidirectional screw 3 to rotate, and the bidirectional screw 3 drives the moving part 1 4 to move along the axial direction of the bidirectional screw 3 and rod 1 5, thereby driving the cylinder 1 7 on plate 1 6 to move toward the middle of plate 2 26, and thereby driving the clamping plate 10 to clamp the aluminum profile.

[0039] When the multiple clamping plates 10 clamp the aluminum profile, they clamp the aluminum profile from both sides and ends respectively, so that the aluminum profile to be sawed is limited and fixed by the multiple clamping plates 10.

[0040] When the clamping plate 10 clamps the aluminum profile, the clamping plate 10 moves, thereby driving the piston shaft 9 to move in the inner cavity of cylinder 1 7, and then pushing the air in the inner cavity of cylinder 1 7 into tube 1 11, and then entering the inner cavity of cylinder 2 15 under the piston plate 17 through the one-way air outlet valve 13 and the telescopic tube 14; and the pressure applied to the piston plate 17 by the spring 2 16 drives the piston plate 17 to compress the air in the inner cavity of cylinder 2 15, and at this time the blocking part 23 is located at the connection between tube 2 19 and cylinder 3 21, and the air in the inner cavity of cylinder 2 15 cannot be discharged.

[0041] Then, the motor 2 31 is started to drive the driving screw 32 to rotate, and the rotation of the driving screw 32 drives the moving part 2 33 threadedly matched with it to move along the direction of the driving screw 32 and the rod 3 34, thereby driving the sawing part 39 to move toward the aluminum profile. At the same time, the motor 36 is started to drive the transmission wheel 1 37 to rotate, and then the transmission wheel 1 37 drives the transmission wheel 2 38 to rotate, thereby driving the sawing part 39 to rotate through the transmission wheel 2 38, thereby cutting the aluminum profile through the sawing part 39.

[0042] After sawing is completed, start motor 2 to drive the bidirectional screw 3 to rotate, thereby driving plate 6 to reset away from the aluminum profile. At this time, cylinder 7 drives the clamping plate 10 to move, and the elasticity of spring 8 drives the piston shaft 9 to move in the inner cavity of cylinder 7 toward the clamping plate 10, thereby resetting the clamping plate 10. When the piston shaft 9 is reset in the inner cavity of cylinder 7, the external air is drawn into the inner cavity of cylinder 7 through the one-way air intake valve 12.

[0043] When tube 1 7 contacts the L-plate 25, it pushes the L-plate 25 to move, thereby driving the rod 24 to move, and the rod 24 drives the blocking part 23 to move, so that the blocking part 23 leaves the connection between tube 2 19 and tube 3 21, so that the inner cavities of tube 2 15, tube 2 19, tube 3 21 and the air jet part 20 are connected, and then the compressed air in the inner cavity of tube 2 15 is ejected from the air jet part 20 to the sawing part of the aluminum profile under the pressure of spring 2 16, and the debris at the cutting part is blown into the inclined plate 27, and then the debris falling into the inner cavity of the inclined plate 27 enters the collection box 29 for temporary storage.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
