[0002] Static electricity is a charge in a static state. Static electricity is not static electricity but electricity that temporarily stays somewhere macroscopically. There are many hazards of static electricity. In industrial production, especially in electronic production and processing and flammable and explosive production sites, static electricity protection should be highly emphasized. In the process of industrial production and processing, plastics, glass, powder, etc. are prone to generate static electricity during the processing production process. Parts that generate static electricity are prone to adsorb dust, and components adsorb each other during the product assembly process, which causes great harm to production and transportation.

[0003] Currently, the existing method for static electricity elimination is to directly connect an electrode to an ion high-voltage power line to form a static elimination rod, and the air is ionized by power-on to generate positive and negative ions. The charged parts need to be in close contact to achieve the static elimination effect. The static elimination distance is short, the efficiency is low, and there is a discharge phenomenon in a dusty and humid environment, posing a safety hazard. The opening of the current ion air knife is fixed and not adjustable, resulting in poor static elimination effect. Summary of the Utility Model

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0024] As Figures 1 to 6 shown, an adjustable static elimination ion air knife in this embodiment includes an air knife cover plate 1, an air knife bottom plate 2, a fixing screw 3 for fixing the air knife cover plate 1 and the air knife bottom plate 2, an adjusting knob 4 for adjusting the position between the air knife cover plate 1 and the air knife bottom plate 2, and an ion generator 5 fixedly arranged on the air knife bottom plate 2. The air knife cover plate 1 is provided with a circular threaded hole, and the air knife bottom plate 2 is provided with a U-shaped threaded hole. The fixing screw 3 sequentially passes through the circular threaded hole and the U-shaped threaded hole. One side of the air knife cover plate 1 close to the air knife bottom plate 2 is provided with a rack 11, and the air knife bottom plate 2 is provided with an adjusting knob 4 passing through it. The adjusting knob 4 meshes with the rack 11. The adjustable static elimination ion air knife in this embodiment includes the air knife cover plate 1 and the air knife bottom plate 2. The fixing screw 3 passes through the circular threaded hole and the U-shaped threaded hole, so that the air knife cover plate 1 and the air knife bottom plate 2 are relatively fixedly connected, and the air knife bottom plate 2 can move relatively along the U-shaped threaded hole, which is convenient for the adjustment of the adjusting knob 4. Specifically, the air knife cover plate 1 is provided with a rack 11, and the air knife bottom plate 2 is provided with an adjusting knob 4 passing through it. The adjusting knob 4 is provided with teeth, and the teeth mesh with the rack 11. By rotating the adjusting knob 4, the rack 11 rotates along the adjusting knob 4, thereby driving the air knife cover plate 1 to move, so as to adjust the size of the air outlet 16 and make the static elimination effect better.

[0025] The adjustable static elimination ion air knife of the utility model comprises an air knife cover plate 1, an air knife bottom plate 2 and an ion generator 5. The air knife cover plate 1 is provided with a circular threaded hole, and the air knife bottom plate 2 is provided with a U-shaped threaded hole. A fixing screw 3 passes through the circular threaded hole and is inserted into the U-shaped threaded hole, so that the air knife cover plate 1 and the air knife bottom plate 2 are fixedly connected relatively. A rack 11 is arranged on one side of the air knife cover plate 1 facing the air knife bottom plate 2, and the air knife bottom plate 2 is provided with an adjusting knob 4 which meshes with the rack 11. When adjusting the air outlet 16, rotate the adjusting knob 4 to move the air knife cover plate 1 relative to the air knife bottom plate 2, so as to control the extending amount of the air knife cover plate 1 extending out of the air knife bottom plate 2, and further control the size of the air outlet 16, making the static elimination and dust removal effect better.

[0026] As Figure 1 shown, the ion generator 5 of this embodiment comprises an ionization generating tank 51, plastic blocks 52 arranged on both sides of the ionization generating tank 51, electrode needles 53 arranged between the plastic blocks 52 on both sides and a high-voltage wire 54 for powering the electrode needles 53. The high-voltage wire 54 is electrically connected to the electrode needles 53 and can provide a high voltage capable of generating ionization for the electrode needles 53. The plastic blocks 52 arranged at intervals on both sides have insulation properties, which can avoid the generation of electric arcs between the plurality of electrode needles 53 and ensure the safety performance of the ion generator 5. Preferably, the material of the electrode needles 53 is tungsten metal or tungsten alloy.

[0027] As Figures 3 to 5 shown, a wind groove 12 is recessed on one side of the air knife cover plate 1 close to the air knife bottom plate 2. The wind groove 12 comprises a first short inclined surface 121 and a first long inclined surface 122 which are connected. The first short inclined surface 121 is close to the air outlet 16. Both the first short inclined surface 121 and the first long inclined surface 122 are inclined, so that the air at the air outlet 16 is blown out at a certain inclined angle. At the same time, the air knife cover plate 1 can move relative to the air knife bottom plate 2, so as to adjust the extending length of the air outlet 16, and further adjust the size and angle of the air outlet 16, which is convenient for static elimination and dust removal of products.

[0028] As Figure 3As shown, the ratio of the length of the first short inclined surface 121 to the length of the first long inclined surface 122 in this embodiment is 0.8 - 1:5 - 10. The first short inclined surface 121 has a relatively inclined inclined surface, which can adjust the air outlet angle of the air outlet 16. The length of the first short inclined surface 121 is shorter. After the air knife cover plate 1 is moved out a certain length by adjusting the knob 4, the first short inclined surface 121 is completely extended. When the adjusting knob 4 is rotated continuously, the first long inclined surface 122 will extend, thereby changing the angle and air volume of the air outlet 16. Specifically, the ratio of the length of the first short inclined surface 121 to the length of the first long inclined surface 122 can be 0.8:5, 0.8:7, 0.8:9, 0.8:10, 0.9:5, 0.9:7, 0.9:8, 0.9:10, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10.

[0029] As Figure 3 shown, preferably, the depth of the air groove 12 is 0.001 mm - 0.05 mm. Specifically, the depth of the air groove 12 can be 0.001 mm, 0.002 mm, 0.004 mm, 0.005 mm, 0.006 mm, 0.007 mm, 0.008 mm, 0.009 mm, 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm. The bottom surface of the air groove 12 is formed by two inclined surfaces. Therefore, the depth of the air groove 12 changes continuously. At the beginning, the longer the length that the air knife cover plate 1 extends, the deeper the depth of the air groove 12, the thicker the wind force, and the more effective it is to remove heavy dust; when the extended length exceeds the length of the first short inclined surface 121, the depth of the air groove 12 gradually becomes shallower, the wind force is sharper, and it is more effective to remove the static electricity on the product surface.

[0030] As Figure 2 shown, the air knife cover plate 1 of this embodiment is provided with an air inlet pipe 13, and the air inlet pipe 13 is provided with a regulating valve 14. The fan is connected to the air knife cover plate 1 through the air inlet pipe 13, thereby providing continuous air volume to the air knife cover plate 1. The air inlet pipe 13 is provided with a regulating valve 14, and the size of the air inlet volume can be adjusted by rotating the regulating valve 14.

[0031] As Figure 6 shown, the air knife cover plate 1 of this embodiment is provided with an air inlet 15 and a plurality of air outlets 16. The air inlet 15 is communicated with the air outlets 16. The air outlets 16 are located on the side of the air knife cover plate 1 close to the air knife bottom plate 2, and the air inlet pipe 13 is connected to the air inlet 15. The air knife cover plate 1 of this embodiment is provided with a plurality of air outlets 16, making the air outlet more uniform.

[0032] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0033] The above-described embodiments merely represent several implementation manners of the present utility model.
