[0002] Hot air circulating drying ovens, with their high efficiency and energy-saving drying characteristics, have become an indispensable key piece of equipment in many industries such as chemical, food, and electronics.

[0003] However, existing hot air circulating drying ovens generally use fixed-size tray support structures. With the rapid pace of product updates and iterations across industries, the shapes and sizes of materials are constantly changing. For example, in the food industry, baking molds from different manufacturers vary in size, and in the electronics industry, the dimensions of new electronic components are becoming increasingly precise. However, existing fixed-size tray support structures are difficult to adapt to trays of different sizes. When faced with incompatible trays, workers are either forced to replace the entire drying equipment or undertake complex modifications. Equipment replacement not only requires a significant investment in new equipment but also results in the idle and wasted existing equipment. Modification involves multiple steps such as disassembly, redesign, and reinstallation, making the process cumbersome, consuming a lot of manpower, and severely extending the production cycle, significantly increasing operating and time costs. This greatly reduces the equipment's versatility and makes it difficult to meet the diverse production needs of enterprises. Utility Model Content

[0018] Please see Figures 1-4The present invention provides the following technical solution: a drying oven body 1, a lower support frame 2 and an upper support frame 21 are slidably connected to the inner wall of the drying oven body 1, a central frame 22 is connected between the lower support frame 2 and the upper support frame 21, four sliding rods 3 are slidably connected to the lower support frame 2 and the upper support frame 21, a connecting rod 31 is installed on one side of each sliding rod 3, an outer mounting plate 32 is installed between the connecting rods 31, an inner support plate 24 is installed on both sides of the inner mounting plate 23, an outer support plate 33 corresponding to the inner support plate 24 is installed on one side of the outer mounting plate 32, a vertical plate 34 is installed between the lower support frame 2 and the upper support frame 21, an upper hinge rod 35 is hinged to one side of the vertical plate 34, a lower hinge rod 36 is hinged to one end of the upper hinge rod 35, a slider 37 is slidably connected to the inner wall of the vertical plate 34, the slider 37 is hinged to one end of the lower hinge rod 36, and the connection between the upper hinge rod 35 and the lower hinge rod 36 is rotatably connected to the outer mounting plate 32 through a rotating rod 361.

[0019] In this implementation scheme: the drying oven body 1 is fixedly installed as the supporting foundation of the entire device. A lower support frame 2 and an upper support frame 21 are installed on the inner wall of the drying oven body 1, forming a sliding connection with the inner wall of the drying oven body 1. This allows the lower support frame 2 and the upper support frame 21 to slide within the drying oven body 1. A central frame 22 is installed between the lower support frame 2 and the upper support frame 21, achieving a stable connection between them. Connecting rods 31 are installed on the same side of the sliding rod 3, and the connecting rods 31 are connected to the outer mounting plate 32 to ensure a secure connection. The connecting rods 31 and the sliding rods 3 of the outer mounting plate 32 are installed on the lower support frame 2 and the upper support frame 21, allowing the sliding rods 3 to slide on the lower support frame 2 and the upper support frame 21. The inner mounting plate 23 has inner support plates 24 installed on both sides, and an outer support plate 33, horizontally corresponding to the inner support plate 24, is installed on one side of the outer mounting plate 32. This supports the bottom of both ends of the material tray, allowing the device to select an appropriate tray according to the size of the material to be dried. The sliding rod 3 can then slide according to the tray size, adjusting the distance between the outer support plate 33 and the inner support plate 24 to match the tray size. When adjustment of the sliding rod 3 is needed, a vertical plate 34 is installed between the lower support frame 2 and the upper support frame 21. One end of the upper hinge rod 35 is hinged to one side of the vertical plate 34, and the other end is hinged to the lower hinge rod 36. The slider 37 is installed inside the vertical plate 34. The slider 37 is slidably connected to the inner wall of the vertical plate 34, and one end of the slider 37 is hinged to the lower hinge rod 36. The connection between the upper hinge rod 35 and the lower hinge rod 36 is rotatably connected to the outer mounting plate 32 via the rotating rod 361. This allows the device to adjust the angle between the lower hinge rod 36 and the upper hinge rod 35 by controlling the height of the slider 37 on the inner wall of the vertical plate 34. After the angle between the upper hinge rod 35 and the lower hinge rod 36 changes, the support position of the upper hinge rod 35 and the lower hinge rod 36 on the outer mounting plate 32 can be adjusted. This, in turn, adjusts the position of the slider 3, the connecting rod 31, and the outer mounting plate 32 between the lower support frame 2 and the upper support frame 21, thereby adjusting the distance between the outer mounting plate 32 and the center frame 22. After adjusting the distance between the outer support plate 33 and the inner support plate 24 to correspond to the size of the pallet, the upper hinge rod 35 and the lower hinge rod 36 support the outer side of the outer mounting plate 32, ensuring the device provides stable support for the pallet. This allows the device to be appropriately adjusted according to the size of the material pallet used, enabling it to support pallets of various sizes for easy use by staff. At the same time, the lower support frame 2 and the upper support frame 21 can slide to the inner wall of the drying chamber body 1, allowing the lower support frame 2 and the upper support frame 21 to slide out, making it easy to place the pallet inside them. It also facilitates the simultaneous removal of the dried pallet, making the pallet easy to separate.

[0020] The lower support frame 2 has a limiting groove 25, and a sliding plate 26 is slidably connected to the inner wall of the limiting groove 25. The sliding plate 26 is connected to the bottom end of the sliding rod 3. The limiting groove 25 on the lower support frame 2 can connect and limit the sliding plate 26, so that the sliding plate 26 can slide stably in the inner wall of the limiting groove 25. At the same time, the sliding plate 26 is connected to the bottom end of the sliding rod 3, so that the sliding rod 3 can be limited by the limiting groove 25 and the sliding plate 26, so that it is limited between the lower support frame 2 and the upper support frame 21, so that the sliding rod 3 can slide and adjust its position, while preventing it from separating from the lower support frame 2 and the upper support frame 21.

[0021] A limiting rod 261 is fixedly connected to the inner wall of the limiting groove 25, and the limiting rod 261 is slidably connected to the slide plate 26. The limiting rod 261 fixedly connected to the inner wall of the limiting groove 25 passes through the slide plate 26, so that the slide plate 26 is slidably connected to the limiting rod 261, so that the slide plate 26 can avoid separating from the inner wall of the limiting groove 25 and can slide in the inner wall of the limiting groove 25.

[0022] Several pulleys 251 are installed at the bottom of the limiting groove 25, and a slide rail matching the pulleys 251 is opened at the bottom of the drying box body 1. The pulleys 251 are used to facilitate the lower support frame 2 to slide on the ground, and can be pushed into the inner wall of the drying box body 1 by corresponding to the slide rail opened at the bottom of the drying box body 1, so that the lower support frame 2 and the upper support frame 21 can be easily installed and separated.

[0023] A motor 38 is installed on the inner wall of the upright plate 34. An adjusting rod 381 is installed on the drive end of the motor 38. The adjusting rod 381 is threadedly connected to the slider 37. A side groove 11 corresponding to the motor 38 is opened on the inner wall of the drying chamber body 1. The motor 38 installed on the inner wall of the upright plate 34 can drive the adjusting rod 381, causing the adjusting rod 381 to rotate. The adjusting rod 381 is threadedly connected to the slider 37, so that the slider 37 can adjust its height on its outer wall under the rotation of the adjusting rod 381, thereby adjusting the angle of the upper hinge rod 35 and the lower hinge rod 36, and adjusting its support position on the external mounting plate 32.

[0024] The outer mounting plate 32 is provided with a clearance groove 321, which is slidably connected to the upper hinge rod 35 and the lower hinge rod 36. The inner wall of the clearance groove 321 is rotatably connected to the connection point of the upper hinge rod 35 and the lower hinge rod 36. The clearance groove 321 provided on the outer mounting plate 32 can make room for the position of the upper hinge rod 35 and the lower hinge rod 36, so that the slider 37 moves down. After the angle of the upper hinge rod 35 and the lower hinge rod 36 increases, part of the upper hinge rod 35 and the lower hinge rod 36 can be located in the clearance groove 321, so as to avoid being limited by the outer mounting plate 32.

[0025] The working principle and usage process of this utility model are as follows: The lower support frame 2 and the upper support frame 21 are slidably connected to the inner wall of the drying chamber body 1. The lower support frame 2 and the upper support frame 21 are then slidably removed from the drying chamber body 1. A suitable material tray is selected based on the size of the material to be dried. The tray size is observed. If it is necessary to adjust the distance between the outer mounting plate 32 and the central frame 22, the motor 38 installed on the inner wall of the vertical plate 34 is started. The motor 38 drives the adjusting rod 381 to rotate. Since the adjusting rod 381 is threadedly connected to the slider 37, the slider 37 adjusts its height on its outer wall as the adjusting rod 381 rotates. As the height of the slider 37 changes, the angle between the lower hinge rod 36 and the upper hinge rod 35 changes. Then, adjust the support positions of the upper hinge rod 35 and the lower hinge rod 36 on the outer mounting plate 32, causing the slide rod 3, the connecting rod 31, and the outer mounting plate 32 to slide between the lower support frame 2 and the upper support frame 21. Adjust the distance between the outer support plate 33 and the inner support plate 24 to a position that matches the size of the tray. After the distance is adjusted, the lower support frame 2 and the upper support frame 21 are slid into the inner wall of the drying box body 1 and fixed by the pulley 251 at the bottom of the limiting groove 25 cooperating with the slide rail at the bottom of the drying box body 1. At this time, the upper hinge rod 35 and the lower hinge rod 36 support the outer side of the outer mounting plate 32 to ensure the stable support of the device on the tray. Start the drying function of the hot air circulating drying box to dry the material placed on the tray.
