[0029] like Figure 1 and Figure 2As shown, the drying device of this embodiment includes a cabinet 100, a support frame 200, a drying unit, and a power unit 500. The front end of the cabinet 100 has a door 110, and the two side walls of the cabinet 100 have ventilation ducts connecting to the interior of the cabinet 100, with hot air blowers connected to the ducts. The support frame 200 is disposed inside the cabinet 100, providing a base for the drying unit and the power unit 500. The drying unit includes a drum assembly 300 and a transmission assembly 400. The drum assembly 300 holds the products to be dried, and the transmission assembly 400 transmits power from the power unit 500 to the drum assembly 300, causing the drum assembly 300 to rotate. The roller assembly 300 comprises a drum body 310, a drum cover 320, and a connecting shaft 330. The drum is used to hold the products to be dried. Several ventilation holes are provided on the side wall of the drum, allowing hot air blown out by ventilation ducts to enter the drum body 310 through these holes. The drum cover 320 is detachably fitted onto the end of the drum. One end of the connecting shaft 330 is connected to the center of the drum cover 320, and the other end is rotatably mounted on a support frame 200. A transmission assembly 400 is mounted on the support frame 200, and the connecting shaft 330 is connected to the transmission assembly 400. The transmission assembly 400 can rotate the drum body 310 via the connecting shaft 330. A power unit 500 is connected to the transmission assembly 400 and is used to drive the roller assembly 300 to rotate via the transmission assembly 400.

[0030] When using the drying device of this embodiment for drying operations, firstly, the cylinder 310 is removed from the cylinder 310 covers connected to its two ends. Then, an appropriate amount of product to be dried is loaded into the cylinder 310. Next, the cylinder 310 is connected to the cylinder 310 covers at both ends. Finally, the cabinet door 110 is closed, the equipment is started, and the drying process begins. During the operation of the drying device of this embodiment, hot air blown out by the ventilation duct enters the interior of the cylinder 310 through the vent holes on the side wall of the cylinder 310. Simultaneously, the power unit 500 drives the drum assembly 300 to rotate via the transmission component 400, causing the product inside the cylinder 310 to continuously tumble, achieving uniform drying. Compared to the traditional tray method, the rotation of the drum not only promotes the penetration and circulation of hot air but also effectively prevents product sticking and damage through rolling and stirring, achieving a more thorough drying effect. In summary, the drying device of this embodiment has a compact structure, achieves high efficiency and high-quality drying effects, and significantly improves production efficiency and product consistency.

[0031] Understandable, such as Figure 3 and Figure 4As shown, in some embodiments, the support frame 200 has limiting blocks 210 on two inwardly facing sides, and limiting grooves 211 on the limiting blocks 210. One end of the connecting shaft 330 is rotatably disposed in the limiting groove 211. At least one connecting shaft 330 of the roller assembly 300 is provided with a first gear 340, which is connected to the transmission assembly 400. The setting of the limiting blocks 210 and limiting grooves 211 makes the roller assembly 300 more stably connected to the support frame 200 during rotation. The first gear 340 contacts the transmission assembly 400 to make the cylinder 310 rotate. At the same time, by setting the connecting shaft 330 on the limiting groove 211 of the limiting block 210, the entire roller assembly 300 can be more easily removed from the cabinet 100, making the loading process more convenient.

[0032] like Figure 4 and Figure 5 As shown, in some embodiments, the transmission assembly 400 includes a transmission shaft 410 and a second gear 420. The transmission shaft 410 is rotatably mounted on the support frame 200, and the second gear 420 is located at one end of the transmission shaft 410 near the cylinder 310. The first gear 340 meshes with the second gear 420, and the other end of the transmission shaft 410 is connected to the power device 500. The meshing of the first gear 340 and the second gear 420 enables a separable connection between the roller assembly 300 and the transmission assembly 400, facilitating the removal of the entire roller assembly 300 from the cabinet 100.

[0033] Furthermore, such as Figure 5 Two transmission assemblies 400 are laterally arranged on the support frame 200 on the same side. The adjacent second gears 420 of the two transmission assemblies 400 are close to each other but do not contact each other. The first gear 340 meshes with the second gears 420 of both transmission assemblies 400 simultaneously. Specifically, the first gear 340 is arranged on the connecting shaft 330 of the roller assembly 300, located between the two second gears 420. With this design, the power unit 500 drives the second gears 420 to rotate through at least one transmission shaft 410, and the second gears 420 then simultaneously drive the first gear 340, causing the roller assembly 300 to rotate.

[0034] like Figure 1 and Figure 2 In some embodiments, a plurality of drying units are vertically arranged inside the cabinet 100. Optionally, the number of drying units inside the cabinet 100 is three. By vertically arranging multiple drying units inside the cabinet 100, the vertical space of the cabinet 100 is fully utilized, enabling the equipment to have a larger drying capacity while occupying the same floor area, thereby improving production efficiency and meeting the needs of modern industry for efficient space utilization.

[0035] Furthermore, such as Figure 6The power unit 500 includes a drive motor (not shown), multiple sprockets 520, and multiple chains 510. Specifically, the multiple sprockets 520 are correspondingly arranged at the other end of the drive shaft 410 of each drying unit. Two adjacent drying units located in the same vertical direction have their sprockets 520 connected by chains 510, forming a series transmission structure. Each sprocket 520 is connected to at most one chain 510, avoiding complex cross-connections of chains 510 and ensuring the simplicity and reliability of the transmission system. The drive motor is directly connected to the drive shaft 410 of one of the drying units. When the drive motor starts, it first drives the drive shaft 410 and the corresponding drum assembly 300 to rotate. Through the transmission connection of the sprockets 520 and chains 510, the rotational motion of the drive shaft 410 is transmitted to the drive shafts 410 of adjacent drying units, sequentially driving the upper or lower drum assemblies 300 to rotate synchronously. In this way, the drum assemblies 300 of multiple drying units can be driven simultaneously by a single drive motor, realizing synchronous operation and centralized control of the equipment.

[0036] In some embodiments, the drive motor is connected to the drive shaft 410 of the drying unit located at the top or bottom of the cabinet 100. This design makes the installation of the drive motor more convenient and the spatial layout more reasonable. Alternatively, the drive motor can be located at the top or bottom of the cabinet 100, and connected to the drive shaft 410 of the drying unit at the top or bottom of the cabinet 100 via a chain 510 or a transmission rod. This design avoids the drive motor operating in the high-temperature environment inside the cabinet 100, reducing the installation and maintenance costs of the equipment.

[0037] In some embodiments, the cabinet 100 is also equipped with a temperature sensor, which is used to regulate the working state of the hot air blower. By accurately controlling the temperature, the material is ensured to be dried within the optimal temperature range, preventing uneven drying caused by overheating or insufficient temperature, and improving product quality.

[0038] In some embodiments, a protrusion is provided around the inner edge of the cabinet door 110, and a recess is provided around the front opening of the cabinet body 100. When the cabinet door 110 needs to be closed, the operator closes the cabinet door 110 towards the cabinet body 100, and the protrusion on the cabinet door 110 gradually enters the recess at the front of the cabinet body 100, until the two are completely fitted together. This structure creates a circumferential seal between the cabinet door 110 and the cabinet body 100, effectively preventing the leakage of internal hot air.

[0039] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
