Description

Technical Field

[0001] This utility model belongs to the field of circulating oven technology, and in particular relates to a circulating oven hot air uniform distribution structure. Background Technology

[0002] A circulating oven is a device that uses forced hot air circulation to achieve heating and drying. It can distribute heat to the surface and gaps of materials, thereby efficiently removing moisture or completing processes such as curing and baking. Through precise temperature control (usually 50℃~300℃) and an adjustable airflow circulation system, it avoids the problems of local overheating or uneven drying in traditional drying. It is widely used in fields such as drying electronic components, dehydrating chemical raw materials, food baking, pharmaceutical sterilization, and laboratory sample processing, and is especially suitable for batch production scenarios with strict requirements for temperature uniformity.

[0003] Existing circulating ovens still have some problems during use. For example, when blowing air, they cannot evenly blow hot air onto the product surface, resulting in uneven heating of the product, affecting the drying effect and product quality. In addition, a lot of dust will adhere to the surface of the filter plate during use, which will increase the resistance to hot air flow and affect the efficiency of hot air circulation. At the same time, the long-term accumulation of dust may also cause secondary pollution, affecting the cleanliness requirements of the product.

[0004] To address these issues, we provide a circulating oven hot air uniform distribution structure. Utility Model Content

[0005] The purpose of this invention is to provide a circulating oven with a uniform hot air distribution structure that can evenly blow hot air onto the product surface and also clean the filter plate. This solves the problem in the prior art that circulating ovens cannot evenly blow hot air onto the product surface and cannot clean the filter plate surface, thus affecting the circulation of hot air and the cleanliness of the product.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a circulating oven structure for uniform hot air distribution, comprising an oven body, a rotating rod rotatably connected inside the oven body, a guide plate fixedly connected to the surface of the rotating rod, an air suction box fixedly connected to the top of the oven body, a placement slot on the top of the air suction box, a filter plate fixedly connected inside the placement slot, heating plates fixedly connected to both sides of the top of the air suction box cavity, an air suction fan fixedly connected to the top of the air suction box cavity, an outer shell fixedly connected to one side of the air suction box, a drive motor fixedly connected to one side of the outer shell, a reciprocating screw fixedly connected to the output end of the drive motor, a threaded sleeve threadedly connected to the surface of the reciprocating screw, a connecting plate fixedly connected to the top of the threaded sleeve, a scraper fixedly connected to the top of one side of the connecting plate, a movable plate fixedly connected to the bottom of the threaded sleeve, a toothed plate provided at the bottom of the movable plate, a gear fixedly connected to one side of the rotating rod surface, the top of the gear meshing with the bottom of the toothed plate, and vertical plates fixedly connected to both sides of the top of the toothed plate.

[0008] The present invention is further configured such that an installation plate is fixedly connected to one side of the oven body, a limit rod is fixedly connected to one side of the installation plate, a slider is slidably connected to the surface of the limit rod, and one side of the slider is fixedly connected to one side of the toothed plate.

[0009] The present invention is further configured such that storage boxes are fixedly connected to both sides of the top of the oven body, and storage boxes are slidably connected inside the storage boxes.

[0010] The present invention is further configured such that a guide rod is fixedly connected inside the outer shell, and a movable plate is slidably connected to the surface of the guide rod.

[0011] The present invention is further configured such that sliding grooves are provided at the top and bottom of the outer shell, and the connecting plate and the moving plate are slidably connected inside the sliding grooves.

[0012] The present invention is further provided that ventilation slots are provided on both sides of the oven body, and dustproof plates are fixedly connected inside the ventilation slots.

[0013] The present invention is further configured such that a door is movably connected to one side of the oven body via a hinge, and an observation window is provided inside the door.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model, through the setting of a transmission motor, can drive the reciprocating lead screw to rotate, thereby driving the threaded sleeve and connecting plate to move laterally, so that the scraper automatically cleans the dust accumulated on the surface of the filter plate, effectively reducing the resistance of hot air flow and maintaining the high-efficiency heat exchange performance of the circulating oven. At the same time, the toothed plate at the bottom of the moving plate meshes with the gear, thereby driving the rotating rod and the guide plate to oscillate periodically, so that the hot air forms a dynamic and uniform distribution in the oven, avoiding the problems of local overheating or uneven drying. This not only improves the uniformity and stability of hot air distribution, but also reduces energy consumption.

[0016] 2. This utility model, through the setting of the scraper, can realize continuous cleaning action, thereby preventing secondary pollution caused by dust accumulation. The dynamic adjustment of the guide plate can adapt to different material placement methods, ensuring that the hot air coverage is without dead corners. Furthermore, the cooperation between the limit rod and the guide rod enhances the stability of the toothed plate and the threaded sleeve when they move, thereby ensuring the stability of the guide plate and the scraper during operation.

[0026] Please see Figures 1-5 Based on Embodiment 1, an installation plate 18 is fixedly connected to one side of the oven body 1, and a limiting rod 19 is fixedly connected to one side of the installation plate 18.

The threaded sleeve 7 drives the connecting plate 8 and the moving plate 10 to move. The connecting plate 8 drives the scraper 9 to move. The scraper 9 cleans the surface of the filter plate 15, thereby pushing the dust on its surface into the storage box 22 to ensure the air permeability of the filter plate 15.

[0028] At the same time, the moving plate 10 will contact one side of the vertical plate 13 and push the toothed plate 11 to move through the vertical plate 13. The toothed plate 11 drives the gear 12 to rotate, the gear 12 drives the rotating rod 2 to rotate, and the rotating rod 2 will drive the guide plate 3 to swing periodically. This allows the air drawn in by the suction fan 17 from the suction box 14 to be heated by the heating plate 16 and then blown evenly onto the material in the drying oven through the dynamically adjusted angle guide plate 3, thereby achieving the purpose of evenly distributing hot air.
