[0016] The output end of the geared motor 2 is connected to the suspension assembly 3 to drive the suspension assembly 3 to rotate. Three electric heating tubes 4 are provided in the two rectangular grooves at the lower end of the drying cabinet body 1. Each rectangular groove corresponds to and is connected to two circular through holes on the bottom surface of the drying cabinet body 1. The control box 8 is electrically connected to the geared motor 2, the electric heating tubes 4 and the fan assembly 6 to realize the control function.

[0017] Specifically, the main body 1 of the drying cabinet serves as the frame structure of the entire drying device, providing the installation foundation and housing space for all components, forming a closed drying environment, and ensuring the stable operation of the drying process; The geared motor 2 outputs power and is connected to the suspension assembly 3 to drive the suspension assembly 3 to rotate, so that the suspended DNPH silicone column mold or the DNPH silicone column with sprayed coating is heated evenly, improving the drying uniformity. The suspension assembly 3 is used to suspend the DNPH silicone column mold or the DNPH silicone column for spraying coatings, and its rotation can drive the object to be dried to rotate. The electric heating element 4 is installed in the rectangular groove at the lower end of the drying cabinet body 1. After being powered on, it generates heat to heat the air entering the drying cabinet body 1 and provides a heat source for the drying process. The diversion plate 5 is welded to the edge of the rectangular groove at the lower end of the drying cabinet body 1. It can divert the heated airflow, making the airflow flow more evenly inside the drying cabinet body 1 and improving the drying effect. The exhaust frame 7 is welded into the rectangular through hole at the upper end of one side of the drying cabinet body 1. It is used to exhaust the airflow inside the drying cabinet body 1, form air circulation, and promote moisture evaporation. The control box 8 is electrically connected to the geared motor 2, the electric heating tube 4 and the fan assembly 6 respectively, and can control the start, stop and operating parameters of these components to achieve overall control of the drying process; The inner cabinet door 9 is installed on the inner edge of the drying cabinet body 1, and the outer cabinet door 10 is installed on the outer edge of the drying cabinet body 1, corresponding to the position of the inner cabinet door 9. When the two are closed together, they can form a closed space, reduce heat loss, and ensure a stable drying environment. The casters 11 are installed on the bottom surface of the drying cabinet body 1 near the four corners, which facilitates the movement and position adjustment of the entire drying device.

[0018] See appendix Figure 1-8 As shown, the suspension assembly 3 includes a rotating short rod 301 welded to the output end of the geared motor 2, the lower end of which is inserted into the through hole at the upper end of the drying cabinet body 1; a main rod 302 fitted on the lower end of the rotating short rod 301; a conical suspension mesh frame 303 welded to both ends of the main rod 302; an inner insertion rod 304 welded to the lower end of the main rod 302; and an outer sleeve 305 fitted on the lower end of the inner insertion rod 304.

[0019] The suspension assembly 3 also includes a limiting member 306 inserted into the upper through hole of the outer sleeve 305, the front end of which passes through the through hole at the lower end of the inner rod 304; a rubber pad 307 glued and fixed inside the limiting member 306; and a rotary knob 308 fitted onto the short post at the front end of the limiting member 306.

[0020] The conical hanging mesh frame 303 is composed of a bracket and a funnel mesh. The lower end of the outer sleeve 305 is inserted into the lower circular through hole inside the main body 1 of the drying cabinet. The rubber pad 307 provides elastic deformation and limits the rotation angle of the rotary knob 308. When the rotary knob 308 is rotated to the horizontal, the limiting member 306 cannot disengage from the inner rod 304 and the through hole of the outer sleeve 305.

[0021] Specifically, the rotating short rod 301 connects the output end of the geared motor 2 to the main rod 302 to transmit rotational power; The main rod 302 serves as the main support structure of the suspension assembly, with both ends connected to the conical suspension mesh frame 303 and the lower end connected to the inner rod 304. The conical hanging mesh frame 303 consists of a support and a funnel mesh, which is used to hang the hooks of DNPH silicone column molds or DNPH silicone column spray coatings. Its shape is conducive to the hanging and heating of the dried items. The inner insert rod 304 works in conjunction with the outer sleeve 305 to provide auxiliary support and positioning for the main rod 302. The outer sleeve 305 is fitted onto the outside of the inner insert rod 304, and its lower end is inserted into the lower circular through hole inside the main body 1 of the drying cabinet to further stabilize the suspension assembly 3. The limiting member 306 is inserted into the through hole of the outer sleeve 305 and the inner rod 304 to fix the two and prevent relative movement. The rubber pad 307 is bonded to the inside of the limiting member 306, providing elastic deformation and limiting the rotation angle of the rotary knob 308; The rotary knob 308 is fitted onto the short post at the front end of the limiting member 306. When rotated to the horizontal position, it can prevent the limiting member 306 from disengaging. When rotated to the vertical position, it is convenient to disassemble the limiting member 306.

[0022] See appendix Figure 1-3 As shown, the fan assembly 6 includes a fan body 601 installed in a through hole on the bottom surface of the drying cabinet body 1, and a filter screen 602 welded to the edge of the bottom surface of the fan body 601.

[0023] Specifically, the fan assembly 6 includes a fan body 601 and a filter 602. The fan body 601 blows air into the drying cabinet body 1, and the filter 602 filters the intake air to ensure that the incoming air is clean and to prevent contamination of the dried items.

[0024] The operation process of this utility model is as follows: When hanging the items to be dried, open the outer cabinet door 10 and the inner cabinet door 9. If the conical hanging mesh frame 303 needs to be replaced, rotate the knob 308 to vertical, pull out the limiting piece 306 from the upper end through hole of the outer sleeve 305, lift the outer sleeve 305 upwards to make it separate from the lower end circular through hole of the drying cabinet body 1, and then pull down the main rod 302 to remove the old mesh frame. Hang the hook of the DNPH silicone column mold or the DNPH silicone column with spray coating on the funnel mesh of the conical hanging mesh frame 303. Then install the hanging assembly 3 in the reverse order of disassembly. When starting the drying process, close the inner cabinet door 9 and the outer cabinet door 10, operate the control box 8, set the drying temperature, time and other parameters, and start the geared motor 2, electric heating tube 4 and fan assembly 6. The geared motor 2 drives the suspension assembly 3 to rotate, which in turn drives the object to be dried to rotate. The fan body 601 draws in filtered air through the filter screen 602 and blows it into the drying cabinet body 1. The electric heating tube 4 heats the air. After being divided by the diverter plate 5, the airflow flows from the bottom to the top, carrying away moisture and being discharged from the exhaust frame 7. When drying is complete, turn off all components through control box 8, wait for the temperature inside the drying cabinet 1 to drop to a suitable range, open the outer cabinet door 10 and the inner cabinet door 9, remove the dried DNPH silicone column mold or DNPH silicone column according to the steps, and close the cabinet door.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
