Description

Technical Field

[0001] This utility model relates to the field of electrostatic powder coating technology, specifically to an electrostatic powder coating equipment for corrosion-resistant and flame-retardant powder coatings. Background Technology

[0002] Corrosion-resistant and flame-retardant powder coatings are powder coatings that combine corrosion resistance and flame retardancy. They are composed of resin, curing agent, pigments, fillers, flame retardants, and other additives. They prevent corrosive media from contacting the coated object through physical barriers and also reduce the corrosivity of the media through chemical corrosion inhibition. In terms of flame retardancy, gas-phase flame retardancy relies on the decomposition of non-flammable gases to dilute the concentration of flammable gases, while condensed-phase flame retardancy relies on the formation of a carbonized layer for heat and oxygen insulation. They are widely used in industries such as construction, electronics, and transportation, for example, in building steel structures, electronic device housings, and automotive parts.

[0003] Corrosion-resistant and flame-retardant powder coatings are generally applied using electrostatic powder coating equipment. However, existing electrostatic powder coating equipment leaves a large amount of powder on the surface of the spraying station after spraying, and it is difficult to recover the excess powder, which is not conducive to the recycling of powder. This leads to increased coating costs for workpieces, reduced production efficiency, and can easily cause environmental pollution and waste. Utility Model Content

[0044] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0045] like Figures 1-4 As shown in the figure, this embodiment proposes an electrostatic powder coating equipment for corrosion-resistant and flame-retardant powder coating, including: an electrostatic powder coating equipment body 1, and further including: a box 2, a lifting frame 3, a hook 4, a collection mechanism, a rotating mechanism, and a lifting mechanism. Two sliding rods 18 are fixedly connected inside the box 2, and two sliding holes are opened on the lifting frame 3. The two sliding rods 18 are slidably connected to the two sliding holes respectively. The electrostatic powder coating equipment body 1 is installed on the box 2. The box 2 has a pick-up and put-out port, and a protective door 20 is hinged at the pick-up and put-out port. The lifting frame 3 is slidably connected inside the box 2. The spraying end of the electrostatic powder coating equipment body 1 is set on the lifting frame 3, and the hook 4 is set inside the box 2. Through the cooperation between the box 2, the lifting frame 3, the hook 4, the collection mechanism, the rotating mechanism, and the lifting mechanism, it is convenient to quickly recover the sprayed powder, reduce dust accumulation and waste, reduce the increase in workpiece spraying costs, improve workpiece production efficiency, and reduce environmental pollution.

[0046] The collection mechanism, located on the housing 2, is used to collect powder. The collection mechanism includes a collection box 5, a dust collection box 6, a gas collection box 7, a conveying pipe 8, a first fan 9, and a filter assembly. The housing 2 has a through hole, through which the conveying pipe 8 extends into the housing 2. The collection box 5 is fixedly connected to one side of the housing 2. The dust collection box 6 is fixedly connected to the lifting frame 3. The gas collection box 7 is connected to the top of the housing 2. The conveying pipe 8 connects the dust collection box 6 and the gas collection box 7. The first fan 9 is located inside the gas collection box 7, with its output end facing inwards towards the housing 2. The filter assembly is located inside the collection box 5 and is used to filter powder. The powder is filtered, and the filter assembly includes a filter plate 10 and a second fan 11. The filter plate 10 is fixedly connected inside the collection box 5, and the second fan 11 is installed on the collection box 5. The output end of the second fan 11 faces one side of the collection box 5. Specifically, the first motor 15 installed on the collection box 5 blows air into the box 2, and then the second fan 11 blows air out of the box 2, causing the conveying pipe 8 and the dust collection box 6 to generate negative pressure, so that the sprayed dust is collected into the box 2 by the collection box and the conveying pipe 8. Then, the filter plate 10 installed inside the box 2 intercepts the dust inside the box 2, thereby collecting the powder.

[0047] The rotating mechanism is mounted on the housing 2 and is used to drive the hook 4 to rotate. The rotating mechanism includes a rotating plate 12, a rotating gear 13, and a driving assembly. The rotating plate 12 is rotatably connected to the housing 2, the hook 4 is fixedly connected to the bottom end of the rotating plate 12, and the rotating gear 13 is fixedly connected to the top end of the rotating plate 12. The driving assembly is mounted on the housing 2 and is used to drive the rotating gear 13 to rotate. The driving assembly includes a driving gear 14 and a first motor 15. A fixed frame 19 is fixedly connected to the housing 2, and the first motor 15 is mounted on the fixed frame 19. The output end of the first motor 15 passes through the fixed frame 19 and is fixedly connected to the driving gear 14. The driving gear 14 is rotatably connected to the housing 2. Specifically, the first motor 15 mounted on the fixed frame 19 drives the driving gear 14 and the rotating gear 13 to rotate. When the rotating gear 13 rotates, it drives the rotating plate 12 and the hook 4 to rotate, thereby driving the workpiece to rotate, thus making the spraying more uniform.

[0048] The lifting mechanism is installed on the housing 2 and is used to drive the lifting frame 3 to move up and down. The lifting mechanism includes a lifting screw 16 and a second motor 17. The lifting screw 16 is rotatably connected inside the housing 2. The lifting frame 3 has a screw hole, and the lifting screw 16 is threaded into the screw hole. The second motor 17 is installed on the housing 2. The output end of the second motor 17 passes through the housing 2 and is fixedly connected to the lifting screw 16. Specifically, the second motor 17 drives the lifting screw 16 to rotate, which in turn drives the lifting frame 3 to move up and down inside the housing 2, thereby driving the spraying end of the electrostatic powder spraying equipment body 1 to move up and down. When the lifting frame 3 moves up and down, it also drives the collection box to move up and down.

[0049] In this embodiment, when spraying the workpiece, the workpiece is hung on the hook 4. The second motor 17 drives the lifting screw 16 to rotate, which in turn drives the lifting frame 3 to move up and down within the housing 2. This, in turn, drives the spraying end of the electrostatic powder spraying equipment to move up and down. The first motor 15 on the fixed frame 19 drives the drive gear 14 and the rotating gear 13 to rotate. When the rotating gear 13 rotates, it drives the rotating plate 12 and the hook 4 to rotate, which in turn drives the workpiece to rotate, thus making the spraying more uniform. During the spraying process, excess powder is absorbed by the absorption box. The first motor 15 on the collection box 5 blows air into the housing 2, and then the second fan 11 blows air out of the housing 2, creating negative pressure in the conveying pipe 8 and the dust collection box 6. The sprayed dust is collected in the housing 2 by the collection box and the conveying pipe 8. Then, the filter plate 10 inside the housing 2 intercepts the dust, thus collecting the powder.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
