Description

Technical Field

[0001] The utility model relates to the technical field of drying oven devices, in particular to a hot air drying oven device. Background Art

[0002] Printing and coating is the process of applying paint, ink, or other materials to the surface of an object to achieve a specific effect or function. After printing and coating, the product needs to be baked to solidify the coating and improve its adhesion. Existing processes typically use hot air ovens to bake the printed products. However, existing hot air ovens often only form a single-directional hot air flow to bake the product. When producing coating products with color requirements, this method will cause uneven surface temperature distribution due to the unidirectional nature of the internal hot air flow and uncontrolled hot air flow direction. This will lead to significant color differences on the surface of the baked product, resulting in poor product appearance, reduced customer satisfaction and market competitiveness.

[0021] Example

[0022] Combine Figures 1 to 3 As shown, this embodiment provides a hot air drying oven device, including a baking area 1 for placing or passing products, air inlet areas 2 are provided on both sides of the baking area 1, and a plurality of guide plates 3 with independently controllable flip angles are provided longitudinally between the baking area 1 and the air inlet areas 2; the hot air from the air inlet area 2 is blown from top to bottom, blown toward the baking area 1 after being guided by the guide plates 3, and blown out from the return air port 7 provided above the baking area 1.

[0023] A plurality of guide plates 3 with independently controllable flip angles are arranged longitudinally between the baking area 1 and the air inlet area 2 to control the direction of the hot air flow. When the hot air from the air inlet area 2 blows from top to bottom, it is guided by the guide plates 3 set at different angles and then blown to the baking area 1, so that all parts of the surface of the product in the baking area 1 can be heated evenly, thereby avoiding obvious color difference on the surface of the product after baking and improving the product appearance yield.

[0024] Specifically, in this embodiment, an air supply channel 4 is provided above the air inlet area 2, with an air inlet 5 provided between the air supply channel 4 and the air inlet area 2. A return air channel 6 is provided above the baking area 1, with a return air outlet 7 provided between the return air channel 6 and the baking area 1. Hot air is circulated by an external circulating fan. An arc-shaped air inlet guide plate 8 is provided between the air inlet 5 and the guide plate 3 to guide the air blown out of the air inlet 5 downward along the sidewalls of the air inlet area 2 via the guide plate 8.

[0025] In this embodiment, a rotating shaft 9 is provided between the baking area 1 and the air inlet area 2, and the guide plate 3 is fixed to the rotating shaft 9. An operating member 10 is provided at one end of the rotating shaft 9 and is located outside the hot air drying device. The operating member 10 can be used to independently rotate the guide plate 3 to control the hot air flow direction at different heights.

[0026] Specifically, it also includes a fixed disk 11, on which a travel groove 12 is provided; the fixed disk 11 is a quarter-circular disk, and the travel groove 12 is an arc-shaped groove. The operating member 10 is an operating handle, which can drive the rotating shaft 9 to rotate to adjust the angle of the guide plate 3, and is fixed to the travel groove 12 by fasteners, and the fasteners can be bolts. The multiple guide plates 3 that can independently control the flip angle form a certain tilt angle by rotating the operating handle, and guide the hot air blown from top to bottom to the middle baking area 1. According to the different structures of the product, multiple guide plates 3 are arranged longitudinally, and different angles can be set respectively to control the flow direction of the hot air, so that all parts of the product surface can be heated evenly, thereby avoiding obvious color differences on the surface of the product after baking.

[0027] Preferably, the fixed plate 11 is provided with scale markings to help the operator better understand the rotation angle of the guide plate 3. Furthermore, when printing, coating, and drying similar or identical products in the future, the operator only needs to adjust the guide plate 3 to the previous angle without further adjustment, thus saving adjustment time and avoiding product rework due to adjustment.

[0028] In this embodiment, a first fixed guide plate 13 is provided at the bottom of the air inlet area 2, and a second fixed guide plate 14 is provided below the baking area. The first fixed guide plate 13 is connected to the bottom of the oven via a bracket and defines a guide channel 15. This allows hot air to be directed through the fixed guide plate and the guide channel 15, then flow upward from the bottom of the baking area 1 to the return air port 7. This allows the hot air to be blown downward from the air inlet area 2 and then flow upward from the bottom of the baking area 1.

[0029] It should be noted that the hot air drying oven device can be a box-type drying oven, in which the product is placed in the box for hot air baking; it can also be the baking device part of the printing and coating plant line, and the baking area 1 has a feed port and a discharge port. The product enters the baking area 1 from the feed port through the transmission device and then exits from the discharge port to enter the next process.
