Technical Field
[0001] This utility model relates to the field of stainless steel coil precision grinding technology, specifically to an antistatic device for stainless steel coil precision grinding. Background Technology
[0002] Stainless steel coil is a type of sheet made of stainless steel. It has excellent corrosion resistance, high strength, heat resistance and good machinability. Fine grinding is one of the production and processing steps of stainless steel coil. It aims to remove welding marks, scratches and dents from the surface of the stainless steel coil through fine grinding, so that its surface can achieve a mirror effect.
[0003] Currently, during the fine grinding process of stainless steel coils, static electricity attracts debris particles to the surface, reducing the appearance quality of the stainless steel coils. Furthermore, after the stainless steel coils are rolled up, friction can easily cause scratches on the surface. Therefore, we propose an antistatic device for the fine grinding of stainless steel coils. Utility Model Content
[0004] The purpose of this invention is to provide an antistatic device for fine grinding of stainless steel coils. During the fine grinding process, the device eliminates static electricity on the stainless steel coils using ion air, and simultaneously collects the debris particles attracted by static electricity. This improves the appearance quality of the stainless steel coils and avoids scratches caused by friction from the adsorbed debris particles after winding. It solves the problem that during the fine grinding process, the surface of stainless steel coils attracts debris particles due to static electricity, reducing the appearance quality of the stainless steel coils. Furthermore, the surface of the stainless steel coils is easily scratched due to friction after winding.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a static eliminator for precision grinding of stainless steel coils, comprising a housing, a high-voltage power generator, and a fan. An air inlet gap and an air outlet gap are respectively provided on both sides of the upper and lower surfaces of the housing. A through inlet is provided on the outer surface of the housing near the air inlet gap, and a through outlet is provided on the outer surface of the housing near the air outlet gap. Dust collection hoods are fixedly installed on both the upper and lower surfaces of the housing near the two air outlet gaps. Isosceles trapezoidal air guide blocks are symmetrically fixedly installed on the top and bottom of the inner wall of the housing. Discharge electrodes are fixedly installed inside the housing near the two air inlet gaps.
[0006] Preferably, a high-voltage power generator is fixedly installed on the front surface of the enclosure, and the high-voltage power generator and the discharge electrode are electrically connected.
[0007] Preferably, a filter is fixedly connected to the input end of the fan, and a dust suction pipe is fixedly connected to the end of the filter, with both ends of the dust suction pipe fixedly connected to the outer surfaces of two dust suction hoods.
[0008] Preferably, limit guide wheels are symmetrically and rotatably installed on both sides of the outer surface of the box near the front and rear surfaces.
[0009] Preferably, air inlet pipes are fixedly installed on the upper and lower surfaces of the housing near the two air inlet gaps. Filter frames are provided inside the two air inlet pipes, and dust filters are fixedly installed inside the two filter frames. Snap-fit protrusions are provided on the outer surfaces of the two filter frames, and snap-fit grooves are provided on the inner walls of the two air inlet pipes, with the snap-fit protrusions located inside the snap-fit grooves.
[0010] Preferably, limit rings are fixedly installed on the inner walls of both air inlet pipes near the two snap-fit grooves.
[0011] Preferably, scrapers are fixedly installed on the inner wall of the box at positions above and below the through-outlet.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up a housing, a through-inlet, a through-outlet, a fan, a dust hood, an inlet gap, an outlet gap, a discharge electrode, a high-voltage power generator, and isosceles trapezoidal air guide blocks, achieves the effect of eliminating static electricity on stainless steel coils during the precision grinding process through ion wind, while simultaneously collecting the debris particles attracted by static electricity. This improves the appearance quality of the stainless steel coils and avoids scratches caused by friction from the surface debris particles after winding. The stainless steel coil enters the housing after passing through the through-inlet and passes between the two isosceles trapezoidal air guide blocks. Afterwards, the air exits through the through-outlet. Once the fan is running, the air enters the interior of the housing through the two air inlet gaps at the top and bottom, and is blown onto the upper and lower surfaces of the stainless steel coil. After passing through the air inlet gaps, the air comes into contact with the discharge electrode, which generates a large number of positive and negative ions with the help of the high-voltage power generator. This creates two ion winds above and below the stainless steel coil. Guided by the isosceles trapezoidal air guide block, the ion winds are blown onto the upper and lower surfaces of the stainless steel coil, eliminating the static electricity carried by the stainless steel coil. After the static electricity is eliminated, the debris particles on the stainless steel coil enter the dust collection hood with the air.
[0014] 2. By setting a limiting guide wheel, this utility model can limit and guide the stainless steel coil passing through the through-inlet and through-outlet, preventing the stainless steel coil from deviating when passing through the box.
[0015] 3. This utility model, by setting up an air inlet pipe, a filter frame, a dust filter, a snap-fit protrusion, and a snap-fit groove, achieves the effect of filtering dust from the outside air entering the housing, while facilitating the disassembly and cleaning of the dust filter. Before the outside air enters the housing through the air inlet gap, the dust filter removes dust and impurities from the air. The filter frame is snapped into the inside of the air inlet pipe by the snap-fit protrusion and snap-fit groove, which facilitates the disassembly, assembly, and cleaning of the filter frame and its internal dust filter.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0022] Example 1
[0023] like Figure 1 , Figure 2 and Figure 4As shown, the present invention proposes an antistatic device for precision grinding of stainless steel coils, comprising a housing 1, a high-voltage power generator 2, and a fan 4. An air inlet gap 11 and an air outlet gap 13 are respectively provided on both sides of the upper and lower surfaces of the housing 1. A through-inlet 10 is provided on the outer surface of the housing 1 near the air inlet gap 11, and a through-outlet 15 is provided on the outer surface of the housing 1 near the air outlet gap 13. During the precision grinding process, the stainless steel coil passes sequentially through the through-inlet 10, the interior of the housing 1, and the through-outlet 15. Limiting guide wheels 7 are symmetrically and rotatably installed on both sides of the outer surface of the housing 1 near the front and rear surfaces. The limiting guide wheels 7 can limit and guide the stainless steel coil passing through the through-inlet 10 and through-outlet 15, preventing the stainless steel coil from shifting when passing through the housing 1. Dust collection hoods 8 are fixedly installed on both the upper and lower surfaces of the housing 1 near the two air outlet gaps 13. A filter 5 is fixedly connected to the input end of the fan 4.
[0024] A suction pipe 6 is fixedly connected to the end of the filter 5, and the two ends of the suction pipe 6 are fixedly connected to the outer surfaces of two suction hoods 8 respectively. Isosceles trapezoidal air guide blocks 12 are symmetrically fixedly installed on the top and bottom of the inner wall of the housing 1. A gap for the stainless steel coil to pass through is provided between the two isosceles trapezoidal air guide blocks 12, and the gap is greater than the thickness of the stainless steel coil. Discharge electrodes 9 are fixedly installed inside the housing 1 near the two air inlet gaps 11. A high-voltage power generator 2 is fixedly installed on the front surface of the housing 1, and the high-voltage power generator 2 and the discharge electrodes 9 are electrically connected. The discharge electrodes 9 generate a large number of positive and negative ions with the cooperation of the high-voltage power generator 2. Scrapers 14 are fixedly installed on the inner wall of the housing 1 above and below the through outlet 15. The two scrapers 14 scrape away the residual debris and impurities adsorbed on the upper and lower surfaces of the stainless steel coil to improve the cleaning effect on the upper and lower surfaces of the stainless steel.
[0025] In use, the stainless steel coil passes through the through inlet 10 and enters the housing 1. It then passes between the two isosceles trapezoidal air guide blocks 12 and exits through the through outlet 15. After the fan 4 starts working, air enters the housing 1 through the two air inlet gaps 11 at the top and bottom and is blown onto the upper and lower surfaces of the stainless steel coil. After passing through the air inlet gaps 11, the air comes into contact with the discharge electrode 9. The discharge electrode 9 generates a large number of positive and negative ions with the cooperation of the high-voltage power generator 2, thus forming two ion winds above and below the stainless steel coil. The ion winds are blown onto the upper and lower surfaces of the stainless steel coil under the guidance of the isosceles trapezoidal air guide blocks 12, eliminating the static electricity carried by the stainless steel coil. After the static electricity is eliminated, the debris particles on the stainless steel coil enter the dust collection hood 8 with the air and are filtered out by the filter 5.
[0026] Example 2
[0027] like Figures 1-4As shown, the present invention proposes an antistatic device for precision grinding of stainless steel coils. Compared with Embodiment 1, this embodiment further includes air inlet pipes 3 fixedly installed on the upper and lower surfaces of the housing 1 near the two air inlet gaps 11. The air inlet pipes 3 are vertically connected, and filter frames 16 are provided inside the two air inlet pipes 3. Dust filters 17 are fixedly installed inside the two filter frames 16. The outer surface of the two filter frames 16 is provided with snap-fit protrusions 19. The inner wall of the two air inlet pipes 3 is provided with snap-fit grooves 18, and the snap-fit protrusions 19 are located inside the snap-fit grooves 18. Limiting rings 20 are fixedly installed on the inner wall of the two air inlet pipes 3 near the two snap-fit grooves 18. The limiting rings 20 limit the filter frames 16.
[0028] In this embodiment, before the outside air enters the housing 1 through the air inlet gap 11, the dust and impurities in the air are filtered out by the dust filter 17 to prevent the dust and impurities from entering the housing 1. The filter frame 16 is snapped into the air inlet pipe 3 by the snap-fit protrusion 19 and the snap-fit groove 18, which facilitates the disassembly, assembly and cleaning of the filter frame 16 and the internal dust filter 17.
