[0002] The hot air circulation drying box uses a hot air circulation system to allow hot air to continuously flow inside the oven, evenly contacting all surfaces of the dried items, thereby achieving rapid drying. The hot air is continuously heated and reused during the circulation process, which improves energy utilization and reduces energy consumption. Hot air circulation drying boxes are usually used in conjunction with self-locking racks, which use the self-locking racks to carry the materials. The self-locking racks drive the materials into the drying box for drying. The internal space of the hot air circulation drying box is limited. At present, in order to be able to place more materials in the same batch, the space of each layer of trays or brackets in the racks is usually compressed. However, this method is not convenient for placing and removing materials. The trays or brackets on some racks are removable, but there are many trays. Extracting and reinserting them layer by layer is cumbersome and time-consuming, which is inefficient. Utility Model Content

DETAILED DESCRIPTION

[0017] See also Figure 1-Figure 5The cam 21 is fixedly mounted on the support frame 21 and the support frame 21 is fixedly mounted on the support frame 21. The cam 21 is fixedly mounted on the support frame 21 and the support frame 21 is fixedly mounted on the support frame 21. The cam 21 is fixedly mounted on the support frame 21 and the support frame 21 is fixedly mounted on the support frame 21.

[0018] In this embodiment: the support frame 1 supports the various components and materials of the device through the first bracket 11 and the second bracket 12, and the material tray 2 carries the material through the support frame 21 and the sunken mesh tray 22. The air permeability of the sunken mesh tray 22 is utilized to enable the air flow inside the drying box to pass through the sunken mesh tray 22 and act on the materials at different layers to achieve the drying operation. The first bracket 11 and the second bracket 12 are designed to be openable and closable. When the first bracket 11 and the second bracket 12 are combined, the first bracket 11 drives the triangular wedge 111 to engage with the second bracket 12. In the slot 121 on the bracket 12, the second bracket 12 supports the limit rod 3, and the compression spring 31 elastically pushes the limit rod 3 so that the limit rod 3 can slide into the slot 121. One end of the limit rod 3 extends into the slot 121 space. One side of the limit rod 3 is an inclined surface, and one side of the triangular wedge block 111 is also an inclined surface. When the triangular wedge block 111 is engaged with the slot 121, the inclined surface of the triangular wedge block 111 corresponds to the inclined surface angle and position of the limit rod 3. The triangular wedge block 111 contacts and squeezes the limit rod 3, and the limit The rod 3 is compressed and retracted toward the inside of the second bracket 12, and then the triangular wedge 111 passes over the limit rod 3, and the compression spring 31 pushes the limit rod 3 to extend, and the limit rod 3 blocks the triangular wedge 111 circuit, so that the triangular wedge 111 can drive the first bracket 11 to complete the locking, and the first bracket 11 and the second bracket 12 are fixed to complete the self-locking, which is simple and convenient to operate. Several material trays 2 are combined on the same vertical line and distributed at equal distances. At this time, the device can drive the material into the box for drying. When the first bracket 11 and the second bracket 12 are opened, the first bracket 1 1 and the second bracket 12 drive the several material trays 2 on each of them to rotate, so that the several material trays 2 on the first bracket 11 and the second bracket 12 can be separated, and the several material trays 2 are split into two groups. The material tray 2 on the first bracket 11 will not block the material tray 2 on the second bracket 12 at this time. The spacing between the material trays 2 on the same vertical line is expanded to twice, so that the materials on the support frame 21 and the sunken net disk 22 are easy to take out and place, without having to extract and insert them layer by layer, which is relatively simple to operate, reduces the time consumed, and improves work efficiency.

[0019] A driving block 32 is installed on one side of the limiting rod 3, and a strip hole 122 is opened on one side of the second bracket 12, and the driving block 32 is slidably connected to the inner wall of the strip hole 122; the second bracket 12 makes way for the driving block 32 through the strip hole 122, so that one end of the driving block 32 can pass through the strip hole 122 and connect with the limiting rod 3, and the driving block 32 is outside the second bracket 12, which is convenient for the staff to control the sliding of the limiting rod 3 from the outside, thereby completing the unlocking of the triangular wedge block 111.

[0020] Spherical rolling bodies 33 are rotatably connected to both sides of the limit rod 3, and the spherical rolling bodies 33 are slidably connected to the inner wall of the second bracket 12; when the limit rod 3 slides inside the second bracket 12, it drives several spherical rolling bodies 33 to slide synchronously, and the spherical rolling bodies 33 reduce the friction between the limit rod 3 and the second bracket 12, so that when the triangular wedge block 111 squeezes the limit rod 3, the limit rod 3 can easily complete the contraction work into the second bracket 12.

[0021] Several support blocks 13 are installed on the inner side of the first bracket 11 and the second bracket 12. A limiting groove 131 is provided on one side of the support block 13, and the support frame 21 is snap-connected to the inner walls of the corresponding two limiting grooves 131; the first bracket 11 and the second bracket 12 support the corresponding several support blocks 13 and the support frame 21. When the first bracket 11 and the second bracket 12 are merged, the first bracket 11 and the second bracket 12 drive the corresponding support frame 21 to rotate toward the support block 13, and the support frame 21 is snap-fitted into the corresponding two limiting grooves 131. The support block 13 supports the support frame 21 through the limiting grooves 131, so that the material tray 2 can work more stably.

[0022] The bottom ends of the first bracket 11 and the second bracket 12 are both equipped with several rolling wheels 14, and the opposite sides of the first bracket 11 and the second bracket 12 are fixedly connected with a docking block 15, and the two docking blocks 15 are positioned correspondingly, and one end of the two docking blocks 15 is fixedly connected with a magnetic plate 151, and the two magnetic plates 151 are magnetically adsorbed; the rolling wheels 14 support the first bracket 11 or the second bracket 12, and when the first bracket 11 and the second bracket 12 are opened or merged, the first bracket 11 and the second bracket 12 are moved by the rolling wheels 14 at the bottom, and the first bracket 11 and the second bracket 12 are fully opened and are in a parallel state, and the first bracket 11 and the second bracket 12 drive the corresponding docking blocks 15 to rotate, and then the two docking blocks 15 drive the corresponding magnetic plates 151 to dock, and the two magnetic plates 151 are adsorbed together, so that the first bracket 11 and the second bracket 12 can maintain a stable state for loading or unloading, and the docking of the two docking blocks 15 can limit the first bracket 11 and the second bracket 12 to prevent the first bracket 11 and the second bracket 12 from rotating excessively.

[0023] The working principle and usage process of the present invention: when the device is in use, the first bracket 11 and the second bracket 12 are opened, and the first bracket 11 and the second bracket 12 drive the several material trays 2 on each of them to rotate, so that the several material trays 2 on the first bracket 11 and the second bracket 12 can be separated, and the several material trays 2 are split into two groups. The material tray 2 on the first bracket 11 will not block the material tray 2 on the second bracket 12 at this time. The spacing between the material trays 2 on the same vertical line is expanded to twice at this time, so that the materials on the support frame 21 and the sunken mesh plate 22 are easy to take out and place, and then the first bracket 11 and the second bracket 12 are merged, and the limit rod 3 completes the locking of the triangular wedge block 111. The first bracket 11 and the second bracket 12 complete self-locking, and the several material trays 2 are merged on the same vertical line and are equidistantly distributed. At this time, the device can drive the material into the box for drying.
