Description

Technical Field

[0001] This invention relates to the field of sandblasting technology, specifically to a high-performance aluminum profile sandblasting production line. Background Technology

[0002] Aluminum profile sandblasting utilizes the principle of high-voltage electrostatic corona field. A high-voltage negative electrode is connected to the metal guide rod at the spray gun head, while the workpiece being sprayed is grounded, forming a positive electrode. This creates a strong electrostatic field between the spray gun and the workpiece. When compressed air, acting as the carrier gas, delivers the powder coating from the powder supply tank through the powder pipe to the guide rod of the spray gun, the corona discharge generated by the high-voltage negative electrode on the guide rod produces a dense concentration of negative charges in its vicinity. This causes the powder to acquire a negative charge and enter the high-intensity electrostatic field. Under the combined action of electrostatic force and the carrier gas, the powder is evenly propelled onto the grounded workpiece surface, forming a uniform powder layer. This layer is then heated and cured to form a durable coating.

[0003] Existing aluminum profile sandblasting operations are mainly completed using aluminum profile sandblasting production lines. These lines consist of a first conveyor, a second conveyor, and a sandblasting unit. The first conveyor transports the aluminum profile to the sandblasting unit at the front end, while the second conveyor transports the sandblasted aluminum profile to its rear end. Flexible curtains are installed at both ends of the sandblasting unit to facilitate the entry and exit of the aluminum profile and the discharge of compressed air. This structure has the following disadvantages:

[0004] 1. During use, the gaps in the soft door curtain allow some of the powder carried away by the high-pressure gas to pass through, causing pollution to the working environment and harming the health of the workers.

[0005] 2. During use, the soft curtain obstructs the high-pressure airflow, thus limiting the airflow and affecting the sandblasting efficiency. Summary of the Invention

[0006] To address the problems existing in the prior art, the present invention provides a high-performance aluminum profile sandblasting production line to solve at least one of the aforementioned technical problems.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0008] A high-performance aluminum profile sandblasting production line includes a first conveying device, a second conveying device, and a sandblasting device. The first conveying device is located at the front end of the sandblasting device, and the second conveying device is located at the rear end of the sandblasting device. Both the front and rear ends of the sandblasting device are equipped with doors. The top of the sandblasting device is equipped with an air duct and a dust collection box. One end of the air duct is connected to the interior of the sandblasting device, and the other end is connected to the interior of the dust collection box. The dust collection box is equipped with an air outlet, and a partition is installed inside the dust collection box, which divides the interior of the dust collection box into a first space and a second space. The air duct is connected to the first space, and the air outlet is connected to the second space. The partition is equipped with ventilation holes, and a filter structure is installed in the first space, which can automatically clean the attached sand and dust.

[0009] Preferably, a first roller, a second roller, and a third roller are installed in the first space. The first roller is located above the second roller, and the third roller is located behind the first and second rollers, abutting against both the first and second rollers. The first roller is rotatably connected to the sandblasting device, and the third roller is slidably connected to the sandblasting device, allowing the third roller to move back and forth. The sandblasting device is equipped with a spring that abuts against the third roller. The first and third rollers are hollow rollers. The first roller has multiple first filter screens arranged circumferentially. A second filter screen is provided at the rear end of the shaft, and the ventilation hole is provided corresponding to the second filter screen. Sealing strips are provided above and below the ventilation hole. One end of the sealing strip is connected to the partition plate, and the other end is connected to the third roller shaft, so that the first space at the edge of the ventilation hole is sealed. The front part of the third roller shaft is provided with a first arc-shaped part and a second arc-shaped part. The first arc-shaped part is in contact with the first roller shaft, and the contact position corresponds to one of the first filter screens. The second arc-shaped part is in contact with the second roller shaft, and the first arc-shaped part is the third filter screen. Brush bristles are provided below the first roller shaft.

During the transport process, the door at the rear end of the sandblasting device is opened. After the transport is completed, the door at the rear end of the sandblasting device is closed. During the sandblasting operation, the high-pressure airflow enters the sandblasting device and then enters the first space through the air inlet duct. After passing through the filter structure, it enters the second space through the ventilation holes and is finally discharged.

[0013] The advantages provided by this invention are as follows:

[0014] 1. It is less likely to cause pollution to the work environment and is beneficial to the health of employees;

[0015] 2. Currently, soft door curtains have less restriction on high-pressure airflow, resulting in relatively high sandblasting efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1, please refer to Figures 1-3 This application provides a high-performance aluminum profile sandblasting production line, including a first conveying device 1, a second conveying device 2, and a sandblasting device 3. The first conveying device is located at the front end of the sandblasting device, and the second conveying device is located at the rear end of the sandblasting device. Existing conveying devices, such as roller conveyors or conveyor belts, can be used for both the first and second conveying devices. Doors 3-1 are provided at both the front and rear ends of the sandblasting device; in this embodiment, sliding doors can be used. An air duct 4 and a dust collection box 5 are provided at the top of the sandblasting device. One end of the air duct communicates with the interior of the sandblasting device, and the other end communicates with the interior of the dust collection box. The dust collector is equipped with an air outlet 5-1 and a partition 5-2 inside, dividing the interior of the dust collector into a first space 5-4 and a second space 5-5. The air duct communicates with the first space, and the air outlet communicates with the second space. The partition has ventilation holes 5-21. A first roller 6, a second roller 7, and a third roller 8 are installed in the first space. The first roller 6 is located above the second roller 7, and the third roller 8 is located behind and abuts against both the first and second rollers. The first roller 8 is rotatably connected to the sandblasting device. The third roller is slidably connected to the sandblasting device, allowing it to move back and forth. A spring 9 is provided on the sandblasting device to abut against the third roller. Both the first and third rollers are hollow. Three first filter screens 6-1 are evenly arranged circumferentially on the first roller. A second filter screen 8-1 is provided at the rear end of the third roller. Ventilation holes are positioned corresponding to the second filter screens. Sealing strips 12 are provided above and below the ventilation holes. These sealing strips can be elastic strips such as rubber or silicone strips, or plastic strips such as cloth strips; no specific limitation is made here. One end of the sealing strip is connected to the... One end is connected to the plate, and the other end is connected to the third roller shaft, so that the first space at the edge of the ventilation hole is sealed; the front part of the third roller shaft is provided with a first arc-shaped part 8-2 and a second arc-shaped part 8-3. The first arc-shaped part is in contact with the first roller shaft, and the contact position corresponds to one of the first filters. The second arc-shaped part is in contact with the second roller shaft. The first arc-shaped part is the third filter. A magnet 11 is fixed below the first roller shaft, and a brush bristle 10 is fixed on the magnet. The first filter is made of a magnetic material, such as iron. The first roller shaft is made of a non-magnetic material, such as plastic or stainless steel.

[0024] In operation, the aforementioned high-performance aluminum profile sandblasting production line works as follows: The first conveying device transports the aluminum profile to the sandblasting device from the front end. During this transport, the door at the front end of the sandblasting device is opened. After transport is complete, the door is closed, and sandblasting begins. After sandblasting is finished, the second conveying device transports the sandblasted aluminum profile to the rear end of the sandblasting device. During this transport, the door at the rear end of the sandblasting device is opened. After transport is complete, the door is closed. During sandblasting, high-pressure airflow enters the sandblasting device and then enters the first space through the air inlet duct. The airflow passes through the first filter screen on the left, the first filter screen on the right, the second filter screen, and the... The three filters enter the second space and are finally discharged. During this process, some of the powder carried away by the high-pressure gas is blocked by the first filter on the left and will not be discharged outside the sandblasting device. When the first filter on the left is clogged, the high-pressure gas accumulates, which increases the pressure on the third roller shaft. The spring is compressed, and the third roller shaft moves backward. At this time, the weight of the first filter on the left increases due to the sand and dust attached to it. The first roller shaft rotates counterclockwise until it stops rotating under the action of a magnet when it is close to the bottom. When the left filter passes through the bristles, the attached sand and gravel are cleaned by the bristles. At this time, the left filter is open, and the third roller shaft is once again in contact with the first and second roller shafts, and so on.

[0025] This high-performance aluminum profile sandblasting production line has the following advantages:

[0026] 1. It is less likely to cause pollution to the work environment and is beneficial to the health of employees;

[0027] 2. Currently, soft door curtains have less restriction on high-pressure airflow, resulting in relatively high sandblasting efficiency.

[0028] 3. The filter structure can automatically clean the attached sand and dust, reducing the workload of the staff.

[0029] It should be noted that the first filter screen can also be set to an odd number such as 5, 7, or 9. A gap can be set between the first roller and the second roller. The second roller can be fixed inside the dust collection box or can be rotatably connected to the dust collection box. This is an option that can be selected by those skilled in the art, and will not be elaborated here.
