[0002] A baking oven is a type of drying equipment, also known as a baking machine. Baking ovens are widely used in precision baking, drying, and shaping processes in optoelectronic, electronic, motor, communication, electroplating, plastic, and mechanical equipment.

[0003] Chinese Patent (Publication No.: CN 213778402 U) discloses a high-efficiency hot air circulating oven. The high-efficiency hot air circulating oven includes a box body, an air inlet pipe, and an air outlet pipe. The box body includes an outer shell, an inner shell, and a door. The door is located on the outer shell, and the inner shell is located inside the outer shell. An air cavity is provided between the outer shell and the inner shell. An air inlet screen is located on the side of the inner shell. The air cavity is a funnel-shaped cavity. The air inlet pipe and the air outlet pipe are located outside the box body. This device has a simple structure, low production cost, and can effectively improve the circulation efficiency of hot air inside the drying oven, increase the contact area between the hot air and the object to be dried, promote heat exchange between the hot air and the object to be dried, improve drying efficiency, and reduce energy consumption. Drying materials is a common and important operation in many industrial production and scientific research processes. Hot air circulating ovens, as a widely used drying equipment, work by circulating hot air inside the oven to exchange heat with the materials, thereby achieving the drying of the materials. Currently, there are some hot air circulating oven technologies on the market designed to improve drying efficiency. Some ovens improve the circulation efficiency of hot air inside the drying chamber by optimizing the internal air duct design and increasing the fan power, thereby promoting heat exchange between the hot air and the objects to be dried, in order to improve drying efficiency and reduce energy consumption. However, these solutions still have certain limitations in practical applications: since the materials are usually in a relatively static state during the drying process, their contact area with the hot air is limited, resulting in some materials not being able to fully contact the hot air, thus affecting the overall drying efficiency and drying uniformity.

[0004] Therefore, a high-efficiency hot air circulating oven is proposed. Utility Model Content

The material drying mechanism includes a servo motor, which is fixedly connected to the back side of the housing. A swing rod is fixedly connected to the output end of the servo motor. A limit groove is formed on the inner side of the swing rod. A first swing plate is slidably connected to the lower part of the inner side of the limit groove. A second swing plate is slidably connected to the upper part of the inner side of the limit groove. A rotating shaft is fixedly connected to the front side of the second swing plate.

Detailed Implementation

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example 1 like Figure 3-6 As shown, this utility model embodiment provides a high-efficiency hot air circulating oven, comprising: Hot air circulating drying device 100 includes a shell 101 made of polyurethane foam. An inner shell 102 is fixedly connected inside the shell 101. A heating fan 103 is provided on the top of the shell 101, and the output end of the heating fan 103 is connected to the inner cavity of the inner shell 102. The material drying mechanism 200 includes a servo motor 201, which is fixedly connected to the back side of the outer shell 101. A swing rod 202 is fixedly connected to the output end of the servo motor 201. A limiting groove 203 is formed on the inner side of the swing rod 202. A first swing plate 204 is slidably connected to the lower part of the inner side of the limiting groove 203, and a second swing plate 205 is slidably connected to the upper part of the inner side of the limiting groove 203. A rotating shaft 206 is fixedly connected to the front side of the second swing plate 205, and a material box 207 is fixedly connected to the front side of the rotating shaft 206. Two partitions 208 are fixedly connected to the back side of the inner cavity of the inner shell 102. 08 is located on the back side of the first swing plate 204, and the first swing plate 204 and the partition 208 are movably connected by a pivot. Another partition 208 is located on the front side of the second swing plate 205, and the second swing plate 205 and the partition 208 are movably connected by a pivot. The swing rod 202 is located between the two partitions 208. The outer surface of the material box 207 is provided with a plurality of equidistant and identically sized air inlets 209. The front side of the material box 207 is hinged to a box door 210. The right side of the box door 210 is movably connected to a card seat 211 by a pivot. The right side of the front side of the material box 207 is fixedly connected to a card block 212, and the card seat 211 is engaged with the outer surface of the card block 212.

[0023] By setting up a material drying mechanism 200, the material can be rotated. During the rotation, all parts of the material have the opportunity to fully contact the hot air. Compared with the traditional method of placing the material statically, this greatly increases the contact area between the material and the hot air, allowing the material to absorb heat more quickly and accelerate the evaporation of moisture, thereby significantly improving the drying efficiency. Furthermore, during the rotation, the heat received by each part of the material is more uniform, effectively avoiding uneven drying caused by insufficient or excessive local heating, and improving the consistency of product quality.

[0024] Example 2 like Figure 1 and Figure 2 As shown, in one embodiment, a heating element 104 is provided between the outer shell 101 and the inner shell 102, and the heating element 104 is U-shaped. A guide plate 105 is fixedly connected to the left and right sides of the top of the inner cavity of the inner shell 102, and the guide plate 105 is inclined. An air inlet net 106 is fixedly connected to the bottom of the inner cavity of the inner shell 102, and the air inlet net 106 penetrates the bottom of the outer shell 101. A light box 107 is fixedly connected to the left and right sides of the inner cavity of the inner shell 102, and an infrared heating tube 108 is provided inside the light box 107.

[0025] By setting the heating element 104, the inner shell 102 can be heated easily. The heating mode can be adjusted according to the needs to avoid running at full load throughout the process. By setting the guide plate 105, the hot air path can be optimized and dead corners can be reduced. By setting the air inlet net 106, the inner shell 102 can be facilitated to exchange heat with the outside environment to avoid excessive temperature. By setting the light box 107 and the infrared heating tube 108, the heating fan 103 can be turned off in the later stage of drying to dry the material at a low temperature and slowly, reducing ineffective energy consumption.

[0026] In operation, this invention works as follows: First, open the door 210, place the material to be dried into the material box 207, close the door 210, and engage the card holder 211 with the outer surface of the card block 212. At this point, the entire device is closed, ensuring a sealed state. The inner shell 102 is heated by the heating element 104, and the material inside the material box 207 is dried by the heating fan 103. During the drying process, the output of the servo motor 201 drives the swing rod 202 to swing. The swing rod 202, during its swing, drives the first swing plate 204 and the second... The swing plate 205 swings, and when the second swing plate 205 swings, it drives the rotating shaft 206 and the material box 207 to rotate, so that the material rotates inside the material box 207. During the rotation, all parts of the material have the opportunity to fully contact the hot air. Compared with the traditional method of placing the material statically, this greatly increases the contact area between the material and the hot air, and the material can absorb heat more quickly. In the later stage of drying, the heating fan 103 can be turned off and the infrared heating tube 108 can be turned on to dry the material slowly at a low temperature, reducing ineffective energy consumption. After drying, the box door 210 can be opened to take out the material.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
