[0002] Aluminum profiles refer to aluminum alloy profiles. Aluminum profiles are widely used in the industrial field and are a basic material for both military and civilian industries. During the processing of aluminum profiles, the surface of the aluminum profiles needs to be sandblasted. In the existing technology, sandblasting is carried out by a sandblasting machine.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a sandblasting machine for surface treatment of aluminum profiles, including a sandblasting machine body 1, roller conveyor belts 3 installed on both the left and right sides of the sandblasting machine body 1, and a discharge port 4 and a feed port 12 respectively opened on the left and right sides of the sandblasting machine body 1, a sand storage tank 2 installed on the top side of the sandblasting machine body 1, a collection port 14 opened at the bottom of the sandblasting machine body 1, a sandblasting component installed on the top side inside the sandblasting machine body 1, a material blocking component installed on the right side inside the sandblasting machine body 1, an air blowing component installed on the left side inside the sandblasting machine body 1, and two sets of clamping components installed on the front and rear sides inside the sandblasting machine body 1.

[0028] When the sandblasting machine for aluminum profile surface treatment is working, the aluminum profile enters the sandblasting machine body 1 through the feed port 12 and is conveyed by the right roller conveyor belt 3 to the right side of the baffle assembly for limiting. The clamping assemblies on the front and rear sides of the right side clamp and fix the aluminum profile. After the sandblasting assembly is started, the sand in the sand storage tank 2 is sprayed out to sandblast the surface of the aluminum profile. After the left end of the aluminum profile is sandblasted, the left end of the aluminum profile is clamped by the two sets of clamping assemblies on the left side to prevent the clamped area from being unable to be sandblasted. In conjunction with the two sets of clamping assemblies on the right side, the sandblasting of the entire aluminum profile is gradually completed. After the sandblasting is completed, the air blowing assembly on the left side blows away the residual sand on the surface of the aluminum profile through the gas nozzle 22. The cleaned aluminum profile is sent out through the discharge port 4 by the left roller conveyor belt 3, and the waste sand is collected and recycled through the collection port 14 at the bottom.

[0029] The sandblasting assembly includes a second drive motor 32. A mounting frame 30 is fixedly connected to the top side inside the sandblasting machine body 1. A bidirectional screw 31 is rotatably passed between the front and rear sides of the mounting frame 30. The second drive motor 32 is fixedly installed on the rear side of the mounting frame 30. The output shaft end of the second drive motor 32 is fixedly connected to the rear end of the bidirectional screw 31. Sliding plates 33 are slidably connected to the front and rear sides inside the mounting frame 30. Both sets of sliding plates 33 are threaded onto the bidirectional screw 31. An adjustment mechanism is installed on the right side of both sets of sliding plates 33.

[0030] The adjustment mechanism includes a second cylinder 24, which is fixedly installed on the right side of the sliding plate 33. The output shaft end of the second cylinder 24 is fixedly connected to a mounting block 16. The two sets of mounting blocks 16 are provided with mounting grooves 17 on their respective sides. Two sets of rotating rods 18 are rotatably passed between the left and right sides of the mounting grooves 17. The left ends of the two sets of rotating rods 18 are fixedly sleeved with gears 35, and the two sets of gears 35 mesh with each other. A first drive motor 19 is fixedly installed on the right side of the mounting block 16. The output shaft end of the first drive motor 19 is fixedly connected to the right end of one set of rotating rods 18. A sand discharge mechanism is installed on both sets of rotating rods 18.

[0031] The sand discharge mechanism includes a second mounting plate 36, a rotating block 34 fixedly mounted on the rotating rod 18, the second mounting plate 36 fixedly connected to the rotating block 34, and a number of sand-spraying nozzles 37 mounted on the second mounting plate 36. Sand outlets 10 are provided on both the front and rear sides of the sand storage tank 2. The output end of the sand outlet 10 is fixedly connected to a sand conveying pipe 38, and the input ends of the number of sand-spraying nozzles 37 are all fixedly connected to the sand conveying pipe 38 through pipes.

[0032] When the sandblasting assembly is working, the second drive motor 32 drives the bidirectional screw 31 to rotate. The bidirectional screw 31 drives two sets of sliding plates 33 to slide in opposite directions within the mounting frame 30 through a threaded connection, adjusting the lateral position of the sandblasting nozzle 37. The second cylinder 24 on the sliding plate 33 drives the mounting block 16 to move. The two sets of rotating rods 18 within the mounting block 16 are linked by gears 35. The first drive motor 19 drives one set of rotating rods 18 to rotate, synchronously driving the other set of rotating rods 18 to rotate in the opposite direction. The rotating rods 18 adjust the angle of the second mounting plate 36 through the rotating block 34, thereby changing the spray direction of the sandblasting nozzle 37. The sand in the sand storage tank 2 enters the sand conveying pipe 38 through the sand outlet 10 and is finally sprayed out by the sandblasting nozzle 37, completing the sandblasting treatment of the aluminum profile surface.

[0033] The baffle assembly includes an L-shaped baffle 13, which is located on the inside right side of the sandblasting machine body 1. A cylinder 15 is installed on the inner right side of the sandblasting machine body 1, and the output shaft end of the cylinder 15 is fixedly connected to the bottom side of the L-shaped baffle 13.

[0034] When the baffle assembly is in use, if it is necessary to limit the aluminum profile or seal the sandblasting area, cylinder 15 pushes the L-shaped baffle 13 to the working position, closing the opening on the right side of the sandblasting machine body 1. After clamping is completed, cylinder 15 retracts to lower the L-shaped baffle 13, releasing the movement path of the aluminum profile.

[0035] The air blowing assembly includes a compressed air cylinder 6. A placement frame 5 is fixedly connected to the front side of the sandblasting machine body 1. The compressed air cylinder 6 is inserted into the placement frame 5. The output end of the compressed air cylinder 6 is fixedly connected to an air inlet pipe 8. Two sets of mounting plates 20 are fixedly connected to the inner left side of the sandblasting machine body 1. An air inlet valve 21 is installed on each of the two sets of mounting plates 20. A gas nozzle 22 is installed at the output end of the air inlet valve 21. The input ends of the two sets of air inlet valves 21 are fixedly connected to the air inlet pipe 8 through pipes.

[0036] When the air blowing assembly is in use, the compressed air cylinder 6 supplies air to the two sets of air inlet valves 21 through the air inlet pipe 8. The air inlet valves 21 control the gas flow and transmit it to the gas nozzles 22 on the mounting plate 20. When it is necessary to remove residual sand from the surface of the aluminum profile, the air inlet valves 21 open, and the gas nozzles 22 spray high-pressure gas to blow the surface of the aluminum profile in a directional manner, thus completing the cleaning operation.

[0037] The clamping assembly includes a sliding module 11, which is fixedly installed on the inner wall of the sandblasting machine body 1. A sliding block 23 is slidably installed on the sliding module 11, and a cylinder 26 is fixedly installed on the sliding block 23. A bent plate 25 is fixedly connected to the output shaft end of the cylinder 26. Several telescopic rods 28 are installed on the side of the bent plate 25 away from the cylinder 26. A fitting plate 27 is fixedly connected to the other end of the telescopic rods 28, and a spring 29 is sleeved on the telescopic rods 28.

[0038] When the clamping assembly is in use, the sliding module 11 drives the sliding block 23 to slide to the target position, the cylinder 3 26 pushes the bending plate 25 to move outward, causing the bonding plate 27 to press against the surface of the aluminum profile, and the telescopic rod 28, together with the spring 29, provides buffer pressure to ensure that the bonding plate 27 clamps the aluminum profile evenly, while avoiding excessive compression that could cause surface damage.

[0039] The bonding plate 27 is made of rubber. The rubber material provides buffer pressure when clamping the aluminum profile through its elastic properties, avoiding scratches on the surface of the aluminum profile caused by rigid contact. At the same time, it enhances the friction during clamping and ensures that the aluminum profile is fixed and stable.

[0040] A controller 7 is installed on the front side of the sandblasting machine body 1. It is used to centrally control the operating parameters of each component of the sandblasting machine and realize functions such as starting and stopping the equipment and switching working modes through the operation interface.

[0041] A camera 39 is installed on the top side inside the sandblasting machine body 1 to monitor the position and surface treatment effect of the aluminum profile in real time during the sandblasting process. It can be linked with the control system to automatically adjust the sandblasting path or clamping position to ensure uniform treatment.

[0042] The top side of the sand storage tank 2 is provided with a sand inlet 9, which is used to replenish the sand for sand blasting by manual or automatic equipment, so as to ensure the continuous sand supply needs during the sand blasting process.

[0043] Working Principle: When the sandblasting machine for aluminum profile surface treatment is working, the aluminum profile enters the sandblasting machine body 1 through the feed inlet 12 and is conveyed by the roller conveyor belt 3 on the right side. Cylinder 15 pushes the L-shaped baffle 13 to move upward to the inner part of the feed inlet 12, limiting the left end of the aluminum profile. Then, the sliding module 11 on the front and rear sides of the right side drives the sliding block 23 to slide to the target position. Cylinder 3 26 pushes the bending plate 25 to move outward, causing the bonding plate 27 to press against the surface of the aluminum profile. The telescopic rod 28, together with the spring 29, provides buffer pressure to ensure that the bonding plate 27 clamps the aluminum profile evenly, while avoiding excessive compression that could cause surface damage. This clamps and fixes the aluminum profile. Then, the drive motor 2 32 drives the double... Rotating the screw 31, the bidirectional screw 31 drives two sets of sliding plates 33 to slide in opposite directions within the mounting frame 30 via a threaded connection, adjusting the lateral position of the sandblasting nozzle 37. The cylinder 24 on the sliding plate 33 drives the mounting block 16 to move. The two sets of rotating rods 18 within the mounting block 16 are linked by gears 35. The drive motor 19 drives one set of rotating rods 18 to rotate, synchronously driving the other set of rotating rods 18 to rotate in the opposite direction. The rotating rods 18 adjust the angle of the mounting plate 36 via the rotating block 34, thereby changing the spray direction of the sandblasting nozzle 37. The sand in the sand storage tank 2 enters the sand conveying pipe 38 through the sand outlet 10 and is finally sprayed out by the sandblasting nozzle 37, completing the sandblasting treatment of the aluminum profile surface.

[0044] After sandblasting the left end of the aluminum profile, the left end of the aluminum profile is clamped by two sets of bonding plates 27 on the left to prevent sandblasting from being blocked at the clamping point. With the help of the two sets of bonding plates 27 on the right, the sandblasting of the entire aluminum profile is gradually completed. After sandblasting, the compressed air cylinder 6 supplies air to the two sets of air inlet valves 21 through the air inlet pipe 8. The air inlet valves 21 control the gas flow and transmit it to the gas nozzles 22 on the mounting plate 20. When it is necessary to remove residual sand from the surface of the aluminum profile, the air inlet valves 21 are opened and the gas nozzles 22 spray high-pressure gas to blow the surface of the aluminum profile in a directional manner to complete the cleaning operation. The cleaned aluminum profile is sent out through the discharge port 4 by the left roller conveyor belt 3, and the waste sand is collected and recycled through the collection port 14 at the bottom.
