Technical Field

[0001] This utility model relates to a coating drying device, specifically a drying device for powder coating processing. Background Technology

[0002] Drying equipment for powder coating processing refers to the equipment used in the powder coating production process, mainly for removing moisture from the coating to ensure its drying and curing. This equipment typically achieves the drying effect by evaporating the moisture from the coating through heating and stirring.

[0003] Existing powder coating drying equipment typically piles all the powder coatings in a drying chamber and dries them by heating the entire chamber. However, because all the powder coatings are piled together, the powder coatings on the top surface and the powder coatings in the deeper layers are heated at different rates. Even with continuous stirring, some powder coatings will always fail to be stirred to the top surface, resulting in low uniformity of the dried powder coatings. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for powder coating processing, which allows the powder coating to be continuously dispersed and dried, resulting in higher uniformity of all powder coatings after drying, and thus achieving a better drying effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for powder coating processing, comprising a drying chamber, a tilting mechanism, a heater, and a scraping mechanism. The tilting mechanism includes a tilting motor and two support shafts. The tilting motor is fixed to the outside of the drying chamber. An inner support is fixed between the two support shafts. A tilting plate is fixed between the two inner supports. The tilting plate has an arc-shaped design, and multiple tilting scoops are fixed to the bottom of the tilting plate. Each tilting scoop has a material receiving chamber, and the material receiving chamber has several discharge holes penetrating the tilting scoop. The multiple discharge holes are evenly distributed in the material receiving chamber. The scraping mechanism includes a guardrail and multiple intercepting bars. The guardrail has an arc-shaped design, and the multiple intercepting bars are fixed to the inner side of the guardrail and distributed in the circumferential direction of the guardrail. Each intercepting bar has a processing groove, and a scraping blade is fixed in each processing groove.

[0006] Preferably, the drying oven has a hollow cavity structure, and a material guide ramp is provided at the bottom of the cavity.

[0007] Preferably, the support shaft, inner support, and tumbling plate are all located inside the drying chamber, with the two inner supports symmetrical to the two ends of the tumbling plate, and the two support shafts rotatably connected to the drying chamber.

[0008] Preferably, multiple turning spoons are distributed around the circumference of the turning plate, and all multiple turning spoons are close to the bottom of the drying chamber.

[0009] Preferably, there are two side panels, which are symmetrical about both ends of the heater, and each side panel is fixed with a support rod at the end that is far away from each other. The support rod is fixed inside the cavity of the drying oven.

[0010] Preferably, each processing tank has multiple scraper blades fixed inside, and the multiple scraper blades are evenly distributed inside the processing tank.

[0011] Preferably, two feed pipes are fixed on the upper end face of the drying chamber, and a discharge pipe is fixed on the lower end face of the drying chamber.

[0012] Preferably, the heater is suspended inside the drying chamber, and both ends of the heater are fixed with hanging rods, both of which are fixedly connected to the drying chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the operation of the flipping mechanism, continuously tumbles the powder coating in the drying chamber, causing it to be lifted up and constantly approach or contact the heater, so that the powder coating can be continuously dispersed and continuously dried.

[0022] Please see Figure 1 One embodiment of this utility model is a drying device for powder coating processing, including a drying box 1, a flipping mechanism 2 provided on the drying box 1, two feed pipes 5 fixed on the upper end face of the drying box 1, and a discharge pipe 6 fixed on the lower end face of the drying box 1. A valve is installed on the discharge pipe 6, and the valve is prior art.

[0023] Please see Figure 2The drying chamber 1 has a hollow cavity structure. The tilting mechanism 2 includes a tilting motor 21 and two support shafts 22. The tilting motor 21 is fixed to the outside of the drying chamber 1. An inner support 23 is fixed between the two support shafts 22, and a tilting plate 24 is fixed between the two inner supports 23. The tilting plate 24 has an arc-shaped design. A guide ramp 11 is provided at the bottom of the cavity of the drying chamber 1. The arc of the guide ramp 11 is the same as the arc of the tilting plate 24, so as to guide the powder coating towards the discharge pipe 6. The support shafts 22, inner supports 23, and tilting plate 24 are all located inside the cavity of the drying chamber 1, and the two inner supports 22 are fixed to the outside of the drying chamber 1. Support 23 is symmetrical to both ends of the tumbling plate 24, and both support shafts 22 are rotatably connected to the drying box 1. It should be noted that there are two tumbling plates 24, and the two tumbling plates 24 are symmetrical to both ends of the heater 3. This not only makes the structure of the tumbling mechanism 2 stable, but also allows more powder coatings to be tumbled in a short time. The drying box 1 is also equipped with a heater 3 and a scraping mechanism 4. The heater 3 is suspended in the cavity of the drying box 1, and both ends of the heater 3 are fixed with a hanging rod 7. Both hanging rods 7 are fixedly connected to the drying box 1. In this embodiment, the heater 3 adopts a resistance wire or an electric heating tube.

[0024] Please see Figure 3 Multiple material scoops 25 are fixed at the bottom of the tumbling plate 24. Each material scoop 25 is provided with a material chamber 251, and the material chamber 251 is provided with a number of discharge holes 252 that penetrate the material scoop 25. The multiple discharge holes 252 are evenly distributed in the material chamber 251. The multiple material scoops 25 are distributed in the circumferential direction of the tumbling plate 24, and the multiple material scoops 25 are close to the bottom of the drying oven 1 cavity.

[0025] Please see Figure 4 The scraping mechanism 4 includes a guardrail 41 and multiple intercepting bars 42. There are two guardrails 41, both of which are arc-shaped and symmetrical to the two ends of the heater 3. The multiple intercepting bars 42 are fixed to the inner side of the guardrails 41 and are distributed in the circumferential direction of the guardrails 41. Each intercepting bar 42 is provided with a processing groove 421. Multiple scraping blades 43 are fixed in each processing groove 421 and are evenly distributed in the processing groove 421. In this embodiment, the scraping blades 43 are made of rubber or a common brush can be used to extend into the material chamber 251 to scrape off the powder coating in the material chamber 251. Support rods 44 are fixed to the ends of the two guardrails 41 that are far apart from each other. The support rods 44 are fixed in the cavity of the drying oven 1 to keep the structure of the two guardrails 41 stable.

[0026] Please refer to the following: Figures 1 to 4In this invention, powder coating is added into the drying chamber 1 through two feed pipes 5. The rotating motor 21 drives the two tumbling plates 24 and the scoops 25 on them to rotate at a uniform speed, thus tumbling the powder coating. During tumbling, the scoops 25 are close to the bottom of the drying chamber 1, and a portion of the powder coating is scooped out into the material chamber 251. As the scoops 25 rotate, the powder coating is gradually discharged through the discharge hole 252, thus lifting the powder coating and suspending it in the drying chamber 1. This allows the heater 3 to release heat into the drying chamber 1, and the heat is dispersed from the center to the surrounding areas, thus dispersing the heat and the powder coating. This allows for the drying of a large amount of powder coating in a short time and also improves the uniformity of the dried powder coating. After drying, the valve is opened, allowing the powder coating to slide down the guide slope 11 to the discharge pipe 6 and be discharged.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
