[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. The utility model adsorbs and fixes the mesh seat through the magnetic adsorption port. The center of the magnetic adsorption port coincides with the center of the installation hole on the air duct positioned by the positioning structure in the projection on the horizontal plane. The connecting column is driven by the pressing body to move downward to press the mesh seat thereon into the installation hole, and the tight fit overcomes the adsorption force of the mesh seat. Moreover, the part where pressure is applied during the pressing of the mesh seat is the edge position of the mesh seat, which will not cause extrusion to the mesh, ensuring the integrity of the filter component structure.

[0019] 2. The utility model can also be adaptively trimmed according to the pipe diameter of the air duct. The positioning structure is driven by the screw on the basic vertical plate to move left and right on the positioning base to adjust the position of the positioning structure, so as to adapt to the assembly operation of air ducts and filter components with different pipe diameters.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Embodiment 1, as Figure 1 shown, a screen seat pressing device for processing an air duct includes:

[0030] A positioning base 1 is provided with a positioning structure 2 thereon, and the positioning structure 2 is used to limit the position of the air duct;

[0031] A pressing body 3, preferably a cylinder, is vertically installed. A connecting column 4 is installed at the end of the pressing body 3. The pressing body 3 drives the connecting column 4 to approach or move away from the positioning base 1. A magnetic suction port 41 is provided at the bottom of the connecting column 4 (the end away from the pressing body 3). The magnetic suction effect of the magnetic suction port 41 is that a magnetic suction block is installed inside, preferably a permanent magnet.

[0032] During use, place the screen of the screen seat 7 in the magnetic suction port 41, and adsorb the screen seat 7 through the magnetic suction effect so that it does not fall off. Place the air duct 8 on the positioning base 1, and determine the pressing position through the positioning structure 2. Drive the connecting column 4 to descend through the cylinder, and press the screen seat 7 into the installation hole of the air duct 8. When pressing, it is necessary to ensure that the vertical positions of the installation hole and the screen seat 7 are on the same vertical line.

[0033] Embodiment 2, in the pressing device, as Figure 2As shown, a base vertical plate 5 is provided on the positioning base 1. The air cylinder is installed on the top of the base vertical plate 5. A guide rod 51 and a screw rod 52 connected by thread are inserted through the side of the base vertical plate 5. The end of the screw rod 52 is rotatably installed on the positioning structure 2, and one end of the guide rod 51 is fixed on the positioning structure 2. By adjusting the screw rod 52, the position of the positioning structure 2 on the positioning base 1 can be adjusted, so as to meet the pressing requirements for air guide pipes 8 with different pipe diameters, and improve the practicability and versatility of the device.

[0034] As Figure 6 shown, to ensure the stable operation of the guide block 21, a sliding groove 11 is provided on the positioning base 1. A guide block 21 is slidably installed in the sliding groove 11, and a scale is provided at the top of the sliding groove 11. The guide block 21 is installed at the bottom of the positioning structure 2.

[0035] Example 3, in the pressing device, as Figures 3 to 5 shown, the pressing device further includes a positioning frame 6. The positioning frame 6 is of a portal structure and is fixed to the positioning base 1 by bolts.

[0036] A through slot 628 is provided at the center of the top of the positioning frame 6. The through slot 628 is located above the positioning structure 2. The top of the through slot 628 is of a conical structure, and there is an opening on the side facing the placement and removal of the air guide pipe, for removing the pressed air guide pipe 8. Due to the problem that the air pressure of the air cylinder is unstable and the stroke cannot be accurately controlled, and secondly, the air guide pipe 8 is a thin-walled part and the top side of the installation part of the screen seat 7 is of a conical structure. Once the stroke is too large, the problem of crushing the installation hole will occur. By strictly limiting the extreme downward position of the screen seat 7 through the position of the through slot, it is ensured that the installation hole will not be over-pressed or cracked.

[0037] The positioning frame 6 includes a top plate 61 and two side vertical plates 62. The two side vertical plates 62 are installed at the lower side of the ends of the top plate 61. An ear plate 63 is installed at the bottom of the side vertical plate 62, and the ear plate 63 is fixed to the positioning base 1 by bolts.

[0038] Example 4, in the pressing device, the side vertical plate 62 includes an upper plate 621, a lower plate 622 and a return frame 623;

[0039] The height of the top of the lower plate 622 is lower than the height of the bottom of the upper plate 621;

[0040] A through hole is provided at the side bottom of the upper plate 621. The size of the through hole on the side away from the lower plate 622 is larger than that on the side close to the lower plate 622. An elastic pad 624 and a moving toothed plate 625 are arranged in the through hole. A toothed surface (concavely arranged) and a blind hole are provided at the top side of the lower plate 622. The moving toothed plate 625 corresponds to the position of the toothed surface. The return-shaped frame 623 is located outside the top of the lower plate 622 and the bottom of the upper plate 621, and a positioning pin 626 is arranged on the return-shaped frame 623. The positioning pin 626 is adapted to the blind hole. Among them, the positioning pin 626 is preferably a setscrew;

[0041] An extrusion bolt 627 is installed on the return-shaped frame 623, and the extrusion bolt 627 is used to act on the side of the moving toothed plate 625 facing away from the toothed surface.

[0042] After the positioning structure 2 is adjusted in position due to the change in the pipe diameter size, the downward position of the screen seat 7 will also change. By loosening the extrusion bolt 627, the moving toothed plate 625 will disengage from the toothed surface under the action of the elastic pad. Then, after adjusting the vertical position of the upper plate 621 to the design elevation, tighten the extrusion bolt 627 to make the moving toothed plate 625 and the toothed surface fit to form a fixed structure.

[0043] As described above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
