Description

Technical Field

[0001] This utility model relates to the field of air supply structure technology, specifically to an air supply structure for an energy-saving drying chamber. Background Technology

[0002] A drying chamber is a device used to dry goods. It heats the air and sends it into the drying chamber through heating and circulating fans, causing the moisture on the surface of the goods to evaporate, thereby achieving the purpose of drying. The working principle of the drying chamber is mainly to heat the air and send it into the drying chamber through heating and circulating fans. After the air in the drying chamber is heated, it becomes drier and is then blown onto the surface of the goods, causing the surface moisture to evaporate and be discharged through the exhaust port. This cycle is repeated until the purpose of drying is achieved. The air inlet of traditional drying chambers is mostly fixed and not easy to adjust. In order to improve this situation, an energy-saving air supply structure for drying chambers is proposed.

[0003] As disclosed in the authorization announcement number CN220648988U, an air distribution structure for a drying chamber includes a drying chamber body, an air inlet device, an air outlet device, and a heat source. The drying chamber body is provided with a glass window, and a sealed insulation door is located on the right side of the glass window. The air inlet device is provided above the drying chamber body. The air inlet device includes an air inlet, a drive motor, and an air inlet fan. An air inlet dust cover is provided at the air inlet. The air outlet device includes an adjustable window, a mounting bracket, an exhaust dust cover, and an exhaust fan. An activated carbon adsorption layer is provided inside the adjustable window. The heat source is located inside the drying chamber body and is fixed to the ceiling and surrounding walls by a mounting bracket.

[0004] Although it has achieved the goal of ensuring the purity of the air in the drying room and improving the drying quality by adding air inlet dust cover and air outlet dust cover, at the same time, adding an activated carbon adsorption layer at the exhaust outlet has a certain purification and filtration effect on the exhaust gas, avoiding the pollution of the environment by the exhaust gas.

[0005] However, the existing air supply structure does not solve the problem that it is not convenient to move and adjust the air supply height and flexibly adjust the air supply angle during use, and it is not conducive to supplying air to the inside of the drying chamber from different positions, thus affecting the flexibility of air supply. Utility Model Content

[0006] The purpose of this utility model is to provide an air supply structure for an energy-saving drying chamber, so as to solve the problem in the background art that the air supply structure is not convenient to move and adjust the air supply height and flexibly adjust the air supply angle, which is not conducive to supplying air to the inside of the drying chamber from different positions and affects the flexibility of air supply.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air supply structure for an energy-saving drying chamber, comprising a drying chamber body and vents. Ventilations are symmetrically installed on the outer wall of the drying chamber body. Mounting brackets are installed on the inner wall of the drying chamber body corresponding to the vents. Integrated frames are symmetrically installed on the side walls of the mounting brackets. Lead screws are movably installed inside the integrated frames. Servo motors are installed at the top of the integrated frames, and the output end of the servo motors is connected to the lead screws. Threaded sleeves are fitted on the surface of the lead screws, and the threaded sleeves are threadedly connected to the lead screws. Lifting frames are installed on the side walls of the threaded sleeves. A fan box is provided on one side of each mounting bracket. Driven shafts are symmetrically installed on the side walls of each fan box. U-shaped frames are provided below each fan box, and the U-shaped frames are connected to the lifting frames. The fan box is movably connected to the U-shaped frames via the driven shafts.

[0008] Preferably, each of the U-shaped frames has an adjusting motor symmetrically installed on its outer wall, and each adjusting motor has a drive shaft installed at its output end.

[0009] Preferably, the surface of the drive shaft is fitted with a drive gear, and the driven shaft surface on one side of the drive gear is fitted with a driven gear, and the drive gear and the driven gear mesh with each other.

[0010] Preferably, each of the fan boxes is equipped with an air outlet pipe, and a hollow ball head is installed at the end of each air outlet pipe away from the fan box, and a hollow ball sleeve is provided on the surface of the hollow ball head.

[0011] Preferably, the fan body is installed inside the fan box, and a heating mechanism is installed at the connection between the air outlet pipe and the fan box.

[0012] Preferably, each of the fan boxes is equipped with an electric push rod at its top, and each of the electric push rods is equipped with a push arm at its output end.

[0013] Preferably, both the upper and lower ends of the hollow ball head are movably mounted with limiting shafts, and the hollow ball sleeve is movably connected to the hollow ball head through the limiting shafts, and connecting arms are fixedly mounted on the surface of the limiting shaft at the top of the hollow ball sleeve.

[0014] Preferably, each push arm is equipped with a linkage shaft at one end near the connecting arm, and the push arm is movably connected to the connecting arm through the linkage shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the air supply structure not only realizes convenient movement and adjustment of air supply height and flexible adjustment of air supply angle, facilitating air supply to the drying chamber from different positions, but also improves the flexibility of air supply.

[0016] (1) By opening the heating mechanism and the fan body, the fan body inside the fan box blows air to the heating mechanism. The heating mechanism heats the airflow and blows it into the interior of the drying chamber through the air outlet, hollow ball head and hollow ball sleeve. The ventilation port plays a role in ventilation. When it is necessary to adjust the air supply height, the servo motor drives the lead screw to rotate. The lead screw drives the lifting frame to move upward through the threaded sleeve. The lifting frame drives the fan box, air outlet, hollow ball head and hollow ball sleeve to move upward through the U-shaped frame, thereby adjusting the air supply height. The adjusting motor drives the transmission gear to rotate through the transmission shaft. The transmission gear drives the driven shaft to rotate through the driven gear. The driven shaft drives the fan box to rotate vertically inside the U-shaped frame. The U-shaped frame drives the air outlet, hollow ball head and hollow ball sleeve to rotate vertically to adjust the air supply angle.

[0017] (2) The push arm is moved by the electric push rod, and the push arm drives the connecting arm to rotate through the linkage shaft. The connecting arm drives a set of limit shafts to rotate, and another set of limit shafts provides movable support for the hollow ball sleeve. The connecting arm drives the hollow ball sleeve to swing left and right on the surface of the hollow ball head, thereby adjusting the direction of air supply laterally and supplying air to the inside of the drying chamber more evenly. The above is the complete usage of the air supply structure of the energy-saving drying chamber. Attached Figure Description
