Technical Field

[0001] This utility model relates to the technical field of cardboard dust removal equipment, specifically an integrated high-pressure air knife device for removing electrostatic paper scraps and dust from the surface of cardboard. Background Technology

[0002] Integrated high-pressure air knife paperboard is a technology used in the papermaking process for cleaning and treating paperboard. The high-pressure air knife in the integrated high-pressure air knife paperboard system generates a high-speed airflow to blow away dirt, dust, and other impurities from the surface of the paperboard. The air outlet of the high-pressure air knife is positioned opposite the paperboard surface at a specific angle, allowing the airflow to effectively remove surface impurities.

[0003] Currently, high-pressure air knives are typically operated manually to remove dust from cardboard surfaces. However, the high-pressure air knife cannot cover the entire cardboard surface during dust removal, requiring manual movement of the air knife. This often results in incomplete dust removal and requires significant physical exertion from workers during extended periods of operation, leading to low work efficiency. To address these technical issues, we have designed an integrated high-pressure air knife device for electrostatic paper scrap and dust removal from cardboard surfaces. Summary of the Invention

The lower end of the fixed tube 54 is connected to a high-pressure air knife 52. The fixed tube 54 is rotatably installed at the bottom of the inner cavity of the adjusting frame 61 via a rotating shaft. An electric push rod 63 is rotatably installed on the top right side of the adjusting frame 61 via a rotating shaft. The telescopic end is rotatably mounted on the right side of the surface of the fixed pipe 54 via a rotating shaft. A suction assembly 7 is fixedly mounted on the right side of the gantry 2. The suction assembly 7 includes an air pump 71, which is fixedly mounted on the top right side of the gantry 2. The air inlet of the air pump 71 is connected to a dust collection box 72 via a pipe. A filter screen 76 is fixedly mounted inside the dust collection box 72. Connecting pipes 74 are connected to both the front and rear sides of the left side of the dust collection box 72. A dust collection hood 75 is connected to the left side of the connecting pipe 74.

[0020] Please see Figure 1 and Figure 3 The inner wall of the support plate 9 is in sliding contact with the surface of the gantry 2. A handle 64 is fixedly installed on the top left side of the adjustment frame 61. The surface of the handle 64 is covered with an anti-slip sleeve. By setting the handle 64, the user can easily hold the handle 64 to pick up the high-pressure air knife 52, so that the dust removal operation can be performed by hand, achieving the effect of manual operation.

[0021] Please see Figure 3 and Figure 4 A connecting frame is fixedly installed at the bottom left side of the adjusting frame 61. The other end of the connecting frame is sleeved and installed at the bottom of the surface of the spring tube 53. By setting the spring tube 53, it is easy to stretch, and the high-pressure air knife 52 can be taken to a greater distance for use, achieving the effect of convenient use.

[0022] Please see Figure 3 and Figure 4The lower end of the high-pressure air knife 52 is connected to an air blowing pipe 55. An air valve 56 is fixedly installed on the surface of the air blowing pipe 55. By setting the air valve 56, the opening and closing of the air blowing pipe 55 can be controlled, so that the high-pressure air knife 52 can open different numbers of air blowing pipes 55 to exhaust air as needed, thereby achieving the effect of adjusting the blowing range.

[0023] Please see Figure 1 The bottom and left side of the dust collection hood 75 are open structures. The dust collection hood 75 is fixedly installed on the top of the base plate 1. By setting the dust collection hood 75, the dust on the cardboard surface can be sucked in more easily, achieving the effect of convenient dust collection.

[0024] Please see Figure 2 A door 73 is rotatably mounted on the right side of the dust collection box 72 via a pivot. A sealing ring is fixedly connected to the side of the door 73 near the dust collection box 72.

By setting the placement plates, the filter screen 76 can be placed so that it can be taken out from the inside of the dust collection box 72 when it needs to be cleaned or replaced.

[0026] In use, place the cardboard on top of the base plate 1, then start the motor 3. The output shaft of the motor 3 drives the threaded rod 4 to rotate, which in turn moves the threaded block 8, thereby moving the support plate 9. This causes the air blowing assembly 5 and the adjusting assembly 6 to move together. Then, start the high-pressure air pump 51 to discharge high-pressure gas from the spring tube 53, the fixed tube 54, and the high-pressure air knife 52. Finally, the gas is blown onto the surface of the cardboard through the air blowing pipe 55. By controlling the number of air valves 56 opened, high-pressure gas is discharged from different numbers of air blowing pipes 55, thus cleaning dust from cardboard of different sizes. Finally, the electric push rod 63 is used to push... The fixed tube 54 is angle-adjustable, allowing the high-pressure air knife 52 to blow air from different angles. When handheld operation is required, the fastening bolt 62 can be removed, causing the adjusting bracket 61 to detach from the surface of the positioning block 10. The worker can then use it by holding the handle 64. At the same time, the suction pump 71 is started, and the dust blown out by the high-pressure gas is sucked in from the dust collection hood 75 and then enters the dust collection box 72 through the connecting pipe 74. The clean air is discharged to the outside of the dust collection box 72 through the filter screen 76, achieving the dust collection effect. When it is necessary to clean the dust inside the dust collection box 72, the dust inside can be cleaned by opening the box door 73.

[0027] In summary, this integrated high-pressure air knife device for removing electrostatic paper scraps and dust from the surface of cardboard solves the problem that current high-pressure air knives for removing dust from cardboard surfaces are usually operated manually, which easily leads to incomplete dust removal and requires a lot of physical effort from workers. This is achieved through the cooperation of motor 3, threaded rod 4, air blowing component 5, adjusting component 6, suction component 7, threaded block 8, support plate 9, and positioning block 10.
