Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-4 A multi-angle air knife includes an air knife structure 1 connected to an installation structure 2. The installation structure 2 includes an installation plate 205. Connectors are provided between both ends of the installation plate 205 and both ends of the air knife structure 1. A groove 207 is provided on the side of the installation plate 205 near the air knife structure 1. The installation plate 205 and the air knife structure 1 are rotatably connected to adjust the angle of the air knife structure 1. The installation plate 205 and the air knife structure 1 are rotatably connected by connectors. During normal use, the installation plate 205 is installed on a supporting object to provide support and angle adjustment for the air knife structure 1. During transportation, the installation plate 205 and the groove 207 are rotated to the air outlet end of the air knife structure 1, and the air outlet end of the air knife structure 1 is inserted into the inner wall of the groove 207. The installation plate 205 seals and protects the air outlet end of the air knife structure 1, reducing the entry of foreign objects.

[0020] Furthermore, the mounting plate 205 is also provided with several mounting holes 206, which are used to cooperate with bolts to install the mounting plate 205 on the corresponding support object, such as a drying device.

[0021] Furthermore, the air knife structure 1 includes an air knife body 101, and the air outlet end of the air knife body 101 is provided with a plurality of air outlet holes 102, which are used to discharge air for cleaning, drying and other operations on the target component.

[0022] Furthermore, the air knife body 101 is also connected to an air inlet pipe 103, which is used to connect to the fan and to connect to the air outlet of the fan through a pipe.

[0023] Furthermore, baffles 104 are installed at both ends of the air knife body 101. A sealing gasket 105 is provided at the connection between the baffle 104 and the air knife body 101. The sealing gasket 105 can be made of rubber. The baffle 104, the sealing gasket 105 and the air knife body 101 are fixed together by bolts.

[0024] Furthermore, the connector includes a support plate 203 installed at the end of the mounting plate 205. The support plate 203 is connected to the mounting plate 205 by bolts. The support plate 203 has an elongated opening 204. A threaded rod 201 is inserted into the inner wall of the elongated opening 204. One end of the threaded rod 201 is fixedly connected to the baffle 104. The threaded rod 201 is welded to the baffle 104. The threaded rod 201 is threadedly connected to a fastening nut 202. The fastening nut 202 is an anti-loosening nut. The threaded rod 201 and the fastening nut 202 are used to fix the position of the support plate 203.

[0025] Furthermore, a pad 208 is fixedly connected to the outer surface of the threaded rod 201. The pad 208 is fixedly connected to the side of the baffle 104, and the pad 208 contacts the support plate 203. The pad 208 is welded together with the baffle 104 and the threaded rod 201.

[0026] Furthermore, the inner wall of the air inlet pipe 103 is provided with threads, and a threaded hole 3 is opened on one of the support plates 203. A threaded plug 301 is threadedly connected to the inner wall of the threaded hole 3. The thread specification of the threaded hole 3 is consistent with the thread specification of the inner wall of the air inlet pipe 103, ensuring that the threaded plug 301 is universal. The threaded plug 301 can be unscrewed from the threaded hole 3 and inserted into the air inlet pipe 103 to seal the air inlet pipe 103.

[0027] Reference Figure 1 In use, the air inlet pipe 103 is connected to the air outlet pipe of the existing fan through a pipe. The pipe is fitted between the outer surface of the air inlet pipe 103 and fixed with existing clamps. After the bolt passes through the mounting hole 206, the mounting plate 205 is fixed to the support object. When adjusting the angle, loosen the fastening nut 202, and then rotate the air knife body 101 with the threaded rod 201 as the center to make multi-angle adjustments. After the adjustment is completed, tighten the fastening nut 202. During transportation, after loosening the fastening nut 202, rotate the mounting plate 205 around the threaded rod 201 to the air outlet 102. Push the mounting plate 205 so that the groove 207 is inserted into the end of the air knife body 101 near the air outlet 102, that is, the groove 207 is inserted into the air outlet end of the air knife body 101. Then tighten the fastening nut 202, unscrew the threaded plug 301 from the threaded hole 3, and screw it into the air inlet pipe 103, that is, as shown. Figure 5 As shown, the overall structure is relatively stable at this time. Figure 1It is more compact, and the air outlet 102 is protected by the mounting plate 205, while the air inlet pipe 103 is protected by the threaded plug 301. When using it again, after loosening the fastening nut 202, push the mounting plate 205 away from the air knife body 101. Rotate the mounting plate 205 to the side of the air knife body 101 with the threaded rod 201 as the center. After adjusting the angle, tighten the fastening nut 202. Unscrew the threaded plug 301 from the air inlet pipe 103 and screw it into the threaded hole 3.
