Description

Technical Field

[0001] This utility model relates to the field of curing oven technology, and in particular to a curing oven for aluminum product coatings. Background Technology

[0002] Aluminum alloy products typically require coatings to be evenly sprayed onto the aluminum alloy surface using specific spraying equipment to form a protective film or decorative layer, which is then cured to form a hard coating. During aluminum alloy surface treatment, such as using powder coating processes, insufficient pre-treatment (e.g., improper removal of oil, dust, or oxide film) can lead to insufficient adhesion between the powder and the aluminum alloy surface. Alternatively, during curing, the powder undergoes physical changes such as thermal shrinkage, causing poorly adhered areas to easily fall off. Furthermore, the aluminum alloy and the attached powder have different coefficients of thermal expansion during heating. When the temperature rises and falls, this difference can generate thermal stress within the powder. If this thermal stress exceeds the bonding force between the powder and the aluminum alloy, some powder will detach from the aluminum alloy surface. These detached impurities, under their own weight, will fall into the furnace body. If they adhere to the heating elements or furnace walls, they may form an insulating layer, reducing heating efficiency and requiring manual cleaning afterwards. Utility Model Content

[0003] This invention provides an aluminum product coating curing oven to solve the problem in the prior art where debris and impurities generated during curing fall into the oven body, causing inconvenience and affecting the performance.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] An aluminum product coating curing oven includes a furnace body. Inside the furnace body, a loading trolley for supporting aluminum products is slidably connected via a track. The oven also includes a collection plate, a drive mechanism, and a collection box. The collection plate is hinged to the inner walls of both sides of the furnace body via a movable frame. The collection plate is located below the loading trolley and is used to collect debris that falls from the aluminum products on the loading trolley during curing. The drive mechanism is located on the furnace body and is used to adjust the collection plate between an inclined state during waste collection and a vertical state during material feeding. The collection box is located below the collection plate and is used to collect debris that falls from the plate.

[0006] Preferably, the driving mechanism includes a motor mounted on the outer wall of the furnace body and a reel mounted on the motor output shaft, wherein a winding rope is connected to the end of the collecting plate away from the movable frame.

[0007] Preferably, the lower end of the loading trolley is connected to a guide member, which is in the shape of an "eight".

[0008] Preferably, the material collection box is slidably connected to the inner wall of the furnace body via a dovetail groove.

[0009] Preferably, the collecting plate has an upwardly bent retaining edge at all edges except the lower edge.

[0010] Preferably, the upper and lower ends of the furnace body are respectively provided with an air outlet and an air inlet, the air inlet and the air outlet are connected by an air supply pipe, and an exhaust fan is provided on the air supply pipe.

[0011] The beneficial effects of this utility model are as follows: the collecting plate below the loading trolley collects the debris generated during the curing of aluminum products, reducing the amount of debris falling into the furnace body and causing long-term accumulation that weakens the heat transfer effect inside the furnace. At the same time, under the action of the driving mechanism, the collecting plate can be moved to a vertical position, so that the collected debris falls into the collection box. During cleaning, the collection box can be pulled out of the furnace body to clean the debris, which is more convenient. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0018] Reference Figures 1-3As shown, an aluminum product coating curing oven includes an oven body 1. A loading trolley 2 for supporting aluminum products is slidably connected to the interior of the oven body 1 via a track. The loading trolley 2 includes a support part 21 slidably connected to the inner wall of the bottom of the oven body 1 and a support plate 22 disposed on the support part 21. The position on the support plate 22 where the aluminum product is placed is hollowed out to facilitate the passage of hot airflow within the oven body 1, resulting in a more uniform curing effect on the aluminum product. During the curing process, debris and other impurities may be generated on the surface of the aluminum product. These debris can fall into the oven body 1 and affect heat transfer over a long period. Therefore, this design incorporates collection plates 3 hinged to the inner walls on both sides of the oven body 1 via movable frames 11 to collect debris falling from the loading trolley 2 during curing. The collection plates 3 are located below the hollowed-out portion of the loading trolley 2. When aluminum product debris falls during curing, it can fall onto the collection plates 3, preventing it from falling directly onto the surface. The furnace body 1 is equipped with a mechanism to adjust the collecting plate 3 between its tilted state during waste collection and its vertical state during material feeding. When the supporting trolley enters or exits the furnace body 1, to prevent the tilted collecting plate 3 from obstructing the support part 21, the collecting plate 3 can be driven to a vertical state by the driving mechanism. When the supporting trolley is inside the furnace body 1, the collecting plate 3 can be adjusted to a tilted state for debris collection. In order to facilitate the collection of debris falling from the collecting plate 3, a collection box 4 is provided below the collecting plate 3. The collection box 4 is slidably connected to the inner wall of the furnace body 1 through a dovetail groove 41. When the collecting plate 3 is in a vertical state, the debris on the collecting plate 3 can fall directly into the collection box 4 below. When it is necessary to clean the debris in the collection box 4, the collection box 4 can be directly pulled out from the furnace body 1 for cleaning, without the need for manual entry into the furnace body 1, which improves safety.

[0019] Reference Figure 2 As shown, the driving mechanism further includes a motor 5 mounted on the outer wall of the furnace body 1 and a reel 51 mounted on the output shaft of the motor 5. A winding rope 52 connected to the end of the collecting plate 3 away from the movable frame 11 is attached to the reel 51. The motor 5 drives the reel 51 to rotate, thereby winding the winding rope 52 and causing the collecting plate 3 to swing around the movable frame 11, thus adjusting the collecting plate 3 between the inclined and vertical states. The winding rope 52 can be made of materials such as steel wire rope that can withstand the high temperature baking inside the furnace body 1.

[0020] Reference Figure 2 As shown, the collecting plate 3 is further provided with an upwardly bent baffle 31 at the lower edge. The baffle 31 is made of the same metal material as the main body of the collecting plate 3, such as high-strength aluminum alloy, and is manufactured by an integral molding process to ensure that the baffle 31 is firmly connected to the collecting plate 3 and is not easy to fall off, so as to prevent debris from overflowing from the side of the collecting plate 3.

[0021] Reference Figure 2As shown, the furnace body 1 is further provided with an air outlet 7 and an air inlet 71 at its upper and lower ends, respectively. The air inlet 71 and the air outlet 7 are connected by an air supply pipe 72, and an exhaust fan 73 is provided on the air supply pipe 72. The hot air inside the furnace body 1 rises and is transported to the lower air outlet 7 through the air inlet 71 and the air supply pipe 72 by the exhaust fan 73. Then, it is blown back into the furnace body 1 through the air outlet 7 to realize the circulation of hot air, so that the heat energy can be fully utilized and the curing efficiency can be improved. At the same time, the airflow blown out of the air outlet 7 blows into the guide component 6, and the hot airflow is guided to the upper part of the collection plates 3 on both sides, so that the hot airflow diffuses to both sides to achieve uniform contact of the aluminum products on the hollow area.
