[0002] An air purifier is a home appliance that actively circulates and purifies the air using a built-in fan and filtration system (such as HEPA filters and activated carbon). It effectively removes pollutants from the air, including particulate matter (PM2.5, dust), formaldehyde, odors, and bacteria. Suitable for indoor environments such as homes and offices, it helps improve air quality, reduce allergens, and enhance respiratory health. Some models also feature intelligent monitoring, sterilization, or humidification functions.

[0003] Air filters are an important component of air purifiers and air handling equipment. Their function is to filter dust and harmful substances in the air, ensuring the cleanliness and hygiene of indoor air. In the production process of air filters, there is a process of applying glue to fix the air filter to the frame, and sometimes the air filter needs to be cleaned, so the air filter needs to be dried.

[0004] In existing drying equipment, the filter screen has contact points with the equipment. For example, in conveyor belt drying equipment, the bottom of the filter screen contacts the equipment. This prevents the hot air used for drying from covering all parts of the filter screen, resulting in uneven drying. Some parts may be dry while others are still damp, which can affect the quality of the filter screen when it leaves the factory. Summary of the Invention

[0005] To overcome the problem that most drying equipment has contact points between the filter and the equipment, which prevents the hot air used for drying from covering all parts of the filter and results in uneven drying effect.

Gears are fixedly connected to both ends of the clamping frame. Racks are provided on both sides above the conveyor. The gears and racks mesh with each other.

[0007] Preferably, the conveyor includes a conveyor roller and a conveyor belt. The diameter of the middle part of the conveyor roller is smaller than the diameters of the two ends. The middle part of the conveyor belt is cut off, and a support seat is fixedly connected to the outer surface of the conveyor belt.

[0008] Preferably, the clamping frame includes a fixed frame and a movable frame, and a pivot is provided at one end of the connection between the fixed frame and the movable frame, and the fixed frame and the movable frame are rotatably connected by the pivot.

[0009] Preferably, a clamping block is provided on the inner side of the fixed frame and the movable frame, and a spring is provided on the outer side of the clamping block.

[0010] Preferably, the fixed frame is provided with connecting shafts at both ends, which are rotatably connected to the support base. A limit ring is provided on the outer side of the connecting shaft, and the width of the limit ring is the same as the width of the support base.

[0011] Preferably, the connecting shaft, limiting ring, and gear on the separated side of the fixed frame and the movable frame are designed separately, and a fixing ring is provided on the outer side of the connecting shaft on the separated side. The inner diameter of the two sets of fixing rings is the same as the diameter of the connecting shaft and they are fixed to each other by magnetic attraction.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1-5 This utility model provides an embodiment: a high-efficiency air purifier filter production and drying device, including a drying chamber 1, a conveyor 2, and an air duct assembly. An electric heating rod 5 for heating is installed inside the drying chamber 1. An air duct assembly is also installed inside the drying chamber 1. A moisture-absorbing box 7 is slidably connected to the inside of the drying chamber 1, and the moisture-absorbing box 7 is filled with moisture-absorbing material. The conveyor 2 is installed at the bottom of the drying chamber 1, and a clamping frame 3 for fixing the filter is installed above the conveyor 2. The clamping frame 3 is connected to the conveyor... 2. Rotary connection: Gears 304 are fixedly connected to both ends of the clamping frame 3, and racks 204 are provided on the upper sides of both sides of the conveyor 2. The gears 304 and racks 204 mesh with each other. The filter screen is clamped and fixed by the clamping frame 3, and the clamping frame 3 is rotatably connected to the conveyor 2. The conveyor 2 transports the clamping frame 3, and the drying box 1 performs hot air drying on the transported filter screen. At the same time, when the racks 204 and gears 304 are engaged, the clamping frame 3 rotates when it is transported, so that the drying is more uniform.

[0018] Please see Figure 2 In this embodiment, the conveyor 2 includes a conveyor roller 201 and a conveyor belt 202. The diameter of the middle part of the conveyor roller 201 is smaller than the diameter of both ends. The middle part of the conveyor belt 202 is cut off. A support seat 203 is fixedly connected to the outer surface of the conveyor belt 202. The specially designed conveyor roller 201 and conveyor belt 202 avoid the clamping frame 3 to prevent the rotating clamping frame 3 from colliding with the conveyor roller 201 and conveyor belt 202.

[0019] Please see Figures 3-4In this embodiment, the clamping frame 3 includes a fixed frame 301 and a movable frame 302. A rotating shaft 305 is provided at one end of the connection between the fixed frame 301 and the movable frame 302. The fixed frame 301 and the movable frame 302 are rotatably connected through the rotating shaft 305. A clamping block 306 is slidably connected to the inner side of the fixed frame 301 and the movable frame 302. A spring 307 is provided on the outer side of the clamping block 306. Connecting shafts 303 are provided at both ends of the fixed frame 301. The connecting shafts 303 are rotatably connected to the support base 203. A limit ring 309 is provided on the outer side of the connecting shaft 303. The width of the limit ring 309 is the same as the width of the support base 203. The connecting shaft 303, the limit ring 309, and the gear are located on the separated side of the fixed frame 301 and the movable frame 302. 304 is a split design, and a fixing ring 308 is provided on the outer side of the connecting shaft 303 on the split side. The inner diameter of the two sets of fixing rings 308 is the same as the diameter of the connecting shaft 303 and they are fixed to each other by magnetic attraction. When installing the filter screen, after separating the fixing rings 308, rotate the movable frame 302 to separate the movable frame 302 from the fixed frame 301. Then, place the filter screen between the fixed frame 301 and the movable frame 302, and then connect the movable frame 302 to the fixed frame 301 again. The clamping block 306 contacts the filter screen and is in close contact with the filter screen under the elastic force of the spring 307. While clamping and fixing the filter screen, thickness compensation is performed to prevent clamping instability caused by manufacturing tolerances. The limiting ring 309 and the support base 203 are interlocked to prevent the clamping frame 3 from sliding laterally.

[0020] Please see Figure 5 In this embodiment, the air duct assembly includes an exhaust fan 4 and an intake fan 6. An exhaust fan 4 is provided on the upper inner side of the drying chamber 1, and intake fans 6 are provided on the bottom sides of the drying chamber 1. The exhaust fan 4 blows hot air downwards, and the intake fan 6 blows hot air into the drying chamber 1. The exhaust fan 4 blows hot air downwards to dry the filter screen. The intake fan 6 draws the hot air back at the bottom of the conveyor 2 for heat reuse.

[0021] In use, first fix the filter screen to the clamping frame 3. After separating the fixing ring 308, rotate the movable frame 302 to separate it from the fixed frame 301. Then, place the filter screen between the fixed frame 301 and the movable frame 302, and then reconnect the movable frame 302 to the fixed frame 301. The clamping block 306 contacts the filter screen and, under the elastic force of the spring 307, makes tight contact with the filter screen, thus clamping and fixing the filter screen while providing thickness compensation to prevent instability caused by manufacturing tolerances. The limiting ring 309 and the support base 203 interlock to prevent clamping. The holder 3 slides laterally and is then placed above the support 203. The conveyor 2 transports the holder 3. At the same time, when the rack 204 and gear 304 are engaged, the holder 3 rotates around the axis of the connecting shaft 303 during transport. During the transport process, the heating rod 5 heats the air, the exhaust fan 4 blows hot air downwards to dry the filter screen, and the intake fan 6 draws the hot air back at the bottom of the conveyor 2 for heat reuse. The dehumidifying box 7 absorbs moisture in the air to ensure the dryness of the hot air and also provides a certain dust prevention effect.

[0022] Through the above steps, the filter screen is clamped and fixed by the clamping frame 3, and the clamping frame 3 is rotatably connected to the conveyor 2. The conveyor 2 transports the clamping frame 3, and the drying box 1 dries the filter screen in the conveying process with hot air. At the same time, when the rack 204 and the gear 304 are engaged, the clamping frame 3 rotates during the transport, thereby making the drying more uniform.
