[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please refer to Figure 1 The present invention provides a dryer for removing moisture from products, including a dryer box 1, a chimney 2, a heating device 3, a drum 4, a hopper 5, and an exhaust device 6. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, a door 11 can be hinged to one side of the front of the dryer box 1. The chimney 2 is installed at the air inlet 10 on the top of the dryer box 1 and is connected to the inside of the dryer box 1. The heating device 3 is installed at the top inside of the dryer box 1. The hopper 5 is fixedly installed at the bottom inside the dryer box 1 by the hopper support 7. The two side walls of the roller 4 are rotatably installed on the two inner side walls of the dryer box 1 by the roller bearing 41 and are located between the heating device 3 and the feeding end of the hopper 5. The exhaust device 6 is located on one side of the dryer box 1 and is connected to the inside of the dryer box 1 by the exhaust pipe 61.

[0024] The drying chamber 1 serves as the outer shell of the entire dryer, providing installation space and support for the aforementioned components. Its relatively enclosed structure protects the internal components and prevents heat loss. Outside air enters the drying chamber 1 through the air inlet 10, while the chimney 2 is used to exhaust the moisture generated during the drying process and forms an air circulation channel, ensuring that the moisture generated during the drying process can be discharged in a timely manner, preventing moisture accumulation inside and thus improving the drying effect and efficiency. The exhaust device 6 can also promptly remove the moisture generated during the drying process, maintaining the dryness of the air inside the chamber. It can further cooperate with the chimney 2 to form an airflow circulation, which can shorten the drying time.

[0025] Preferably, the door 11 and the other side frame of the dryer chamber 1 are opened or closed by a lock 12. During equipment operation, the door 11 must be closed to maintain the internal temperature environment and improve drying efficiency.

[0026] like Figure 3 and Figure 4 As shown, the heating device 3 may include several heating tubes 31 and two tube clamps 32. The two ends of the several heating tubes 31 are evenly connected between the two tube clamps 32 and arranged in an array. The heating part of each heating tube 31 is set downwards, which can heat the air inside the drying chamber 1 and provide a stable heat source.

[0027] In order to fix the heating device 3 to the top of the inside of the drying chamber 1, the two sides of the top of the inside of the drying chamber 1 in this embodiment are respectively provided with limiting protrusions 13 for supporting and placing two pipe clamps 32, which can facilitate the installation and disassembly of the heating device 3. Of course, in other embodiments, other fixing methods can also be used for installation, and this embodiment does not limit them.

[0028] In this embodiment, the heating tube 31 can preferably be configured as a circular electric heating tube 31. The circular electric heating tube 31 has the advantages of high heating efficiency and accurate temperature control, and the temperature can be precisely adjusted according to different materials and drying requirements. Of course, in other embodiments, the heating device 3 can be configured as an electric heating wire, a plate heat exchanger, or an electromagnetic induction heating device, etc., and this embodiment does not limit it.

[0029] like Figure 5 As shown, the roller 4 can be provided with an inlet / outlet 42 that connects to its hollow interior. The two side walls and the circumferential surface of the roller 4 are all designed with a hollow structure.

[0030] Specifically, the hollow structure of the drum 4 can be set as several densely distributed ventilation holes or ventilation grilles. The diameter or gap of the ventilation holes or ventilation grilles is smaller than the diameter of the material. This design allows hot air to flow smoothly to the material, increases the contact area between the hot air and the material, and achieves a more uniform drying effect.

[0031] Furthermore, several reinforcing ribs 43 for enhancing the strength and stability of the roller can be fixedly connected to the outer wall surface of the roller 4 around its circumference.

[0032] In practice, the drum 4 is used to carry the material and is driven to rotate by an external rotation drive device (drive motor + reducer) connected to the drum bearing 41. During the rotation, the material is constantly turned over to achieve uniform heating, so that the moisture in the material can evaporate.

[0033] like Figure 6As shown, the bottom of the hopper support 7 may be provided with a downward-sloping shelf 71 for placing the glue frame.

[0034] Preferably, a controller 8 with a display screen and / or buttons can be fixedly installed on the upper side of the outer wall of the dryer box 1. Operators can accurately control the drying process according to different materials and drying requirements, realize automated operation, improve drying effect and production efficiency, and facilitate operators to understand the operation status of the equipment in a timely manner.

[0035] The working principle of this utility model is as follows:

[0036] First, the operator opens the chamber door 11 and puts the material to be dried into the inside of the drum 4 through the inlet / outlet 42. Then, the operator closes the chamber door 11. Outside air enters through the air inlet 10 at the top of the dryer chamber 1. The controller 8 is turned on to regulate the operation of the heating device 3 to heat the air. The external rotary drive device drives the drum 4 to rotate back and forth, so that the hot air can fully contact the material and remove the residual moisture on the material. The humid and hot air formed can be discharged to the outside through the chimney 2. The exhaust device 6 also extracts the humid and hot air from the dryer chamber 1 through the exhaust pipe 61, further accelerating the circulation of air inside the chamber. After drying, the operator opens the chamber door 11 and places the plastic frame on the shelf 71. The external rotary drive device drives the drum 4 to rotate until its inlet / outlet 42 faces downward, so that all the dried material falls into the plastic frame and is taken out, thus completing one drying operation.

[0037] In summary, this invention heats the air using a heating device, and then drives the drum to rotate via an external rotary drive device. This allows the hot air to fully contact the material being turned over and remove any residual moisture. The resulting humid and hot air can be discharged and extracted through a chimney and exhaust device, further accelerating the air circulation inside the chamber. It is easy to operate, runs stably and reliably, dries evenly, and has a good drying effect, thus improving drying efficiency. It is especially suitable for drying sealed products.

[0038] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
