Description

Technical Field

[0001] This utility model relates to the field of coating head technology, and in particular to an automatic air exhaust adjustment device for coating heads. Background Technology

[0002] Coating is a core process in high-end manufacturing fields such as lithium batteries, optical films, and functional coatings. Its core is to uniformly coat the substrate surface with slurry using precision coating equipment. During this process, a large amount of volatile organic compounds (VOCs) and dust are generated in the coating head area due to solvent evaporation. These need to be discharged in time through the exhaust system. Therefore, the automatic ventilation adjustment device for the coating head is one of the essential pieces of equipment in the coating process.

[0003] Existing automatic emission control devices are equipped with filters to remove particulate matter, harmful gases and other pollutants from the air. To achieve better filtration, a double-layer filter structure can be used. However, when disassembling and assembling the filter, it is necessary to remove the filter layer by layer, which reduces the efficiency of filter replacement. Therefore, an automatic exhaust control device for the coating head is needed to quickly remove the double-layer filter from the inside of the air outlet and quickly disassemble and replace the double-layer filter. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic exhaust adjustment device for coating heads, in order to solve the problem mentioned in the background art that existing automatic exhaust adjustment devices are equipped with filters to remove pollutants such as particulate matter and harmful gases from the air. In order to achieve better filtration effect, a double-layer filter structure can be adopted. However, when disassembling and assembling the filter, it is necessary to disassemble the filter layer by layer, which reduces the efficiency of filter replacement.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an automatic airflow adjustment device for coating heads, comprising:

[0007] An exhaust assembly, the exhaust assembly including an air outlet;

[0008] The filter assembly is located inside the air vent and includes a first activated carbon filter, a second activated carbon filter, a connecting frame, a fixing rod, and a silicone column. The first activated carbon filter is located inside the bottom of the air vent. The connecting frame is fixed to the upper surfaces on both sides of the first activated carbon filter. The fixing rod is inserted inside the connecting frame. The second activated carbon filter is fixed to the upper surface of the fixing rod. The silicone column is inserted inside the fixing rod and the connecting frame.

[0009] Furthermore, a movable column is fixed to the outer surface of the silicone column, a spring is fixed to the inner side of the movable column, and a support column is fixed to the outside of the spring.

[0010] Furthermore, connecting rods are fixed to the outer surfaces of both sides of the first activated carbon filter, and mounting posts are fixed to the outer surfaces of both sides of the air outlet. Screws are threadedly connected between the connecting rods and the mounting posts.

[0011] Furthermore, the exhaust assembly also includes an air duct, an exhaust fan, and a duct-type wind speed sensor; the air duct is fixed to the upper surface of the air outlet, the exhaust fan is fixed inside one side of the air duct, and the duct-type wind speed sensor is inserted inside the top of the air outlet.

[0012] Furthermore, it also includes an installation assembly located on the other side of the air vent. The installation assembly includes a fixed plate, a limiting groove, a movable column, and a limiting plate. The fixed plate is fixed to the outer surface of the other side of the air vent, and the upper surface of the fixed plate is in contact with the lower surface of the duct-type anemometer. The limiting groove is opened inside the other side of the fixed plate. The movable column is connected through the interior of the fixed plate, and the limiting plate is fixed to the upper surface of the movable column. The surfaces of the movable column and the limiting plate on one side are in contact with the outer surface of the duct-type anemometer.

[0013] Furthermore, a connecting column is fixed to the lower surface of the movable column, and a threaded column is threadedly connected to the internal threads of the connecting column and the fixing plate. A guide plate is fixed to the lower surface of the threaded column.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through its designed filter components, filters the air intake when the vent is drawing in air using a first and second activated carbon filter. When a duct-type wind speed sensor detects an abnormal wind speed inside the vent, both the first and second activated carbon filters need to be replaced. To replace them, first unscrew the screw from the mounting post, allowing the connecting rod to move downwards. Once the first and second activated carbon filters are detached from the vent, an inward squeezing force is applied to the movable post, causing the silicone column to detach from the connecting frame. This, in turn, applies an upward pulling force to the second activated carbon filter. The first and second activated carbon filters can be separated. The cleanliness of both filters is then assessed. The filter to be replaced is removed, and the fixing rod is inserted into the connecting frame. An inward pressing force is applied to the movable column, compressing the spring. The support column is then moved to the desired height. The force applied to the movable column is released, and the silicone column springs back into the connecting frame under the spring's elasticity. The first and second activated carbon filters are then inserted into the air vent, and the screws are turned into the mounting column. This method allows for quick removal of the double-layer filters from the air vent and rapid disassembly and replacement.

[0016] II. Based on the first beneficial effect, when using the installation components in conjunction with the duct-type anemometer to fix the duct-type anemometer in the required position, first insert the duct-type anemometer into the air outlet, so that the outer surface of the duct-type anemometer is in contact with the air outlet. Then, apply an upward pushing force to the connecting column, and the moving column moves upward inside the fixing plate. When the connecting column can no longer be pushed, apply a rotational force to the guide plate, so that the threaded column rotates into the interior of the fixing plate. This solution can quickly and stably fix the duct-type anemometer in the required position. Attached Figure Description

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-4 As shown, this embodiment is an automatic airflow adjustment device for the coating head, including:

[0030] The exhaust assembly includes an air outlet 11;

[0031] The filter assembly is located inside the air outlet 11. The filter assembly includes a first activated carbon filter 31, a second activated carbon filter 35, a connecting frame 36, a fixing rod 37, and a silicone column 392. The first activated carbon filter 31 is located inside the bottom of the air outlet 11. The connecting frame 36 is fixed to the upper surfaces on both sides of the first activated carbon filter 31. The fixing rod 37 is inserted inside the connecting frame 36. The second activated carbon filter 35 is fixed to the upper surface of the fixing rod 37. The silicone column 392 is inserted inside the fixing rod 37 and the connecting frame 36.

[0032] The first activated carbon filter 31 serves as the primary filtration layer, adsorbing large dust particles and some volatile organic compounds in the exhaust gas. The second activated carbon filter 35 serves as the secondary filtration layer, further adsorbing residual VOCs and fine particles to improve filtration efficiency. The connecting frame 36 is used to connect with the fixing rod 37, thereby connecting the first activated carbon filter 31 and the second activated carbon filter 35 together. The silicone column 392 is used to confine the fixing rod 37 inside the connecting frame 36, and due to the material of the silicone column 392, the fixing rod 37 is more stably fixed inside the connecting frame 36.

[0033] A movable column 391 is fixed to the outer surface of the silicone column 392, a spring 39 is fixed to the inner side of the movable column 391, and a support column 38 is fixed to the outside of the spring 39.

[0034] The movable column 391 is used to change the position of the silicone column 392, the spring 39 provides elastic pressure to the movable column 391 to ensure locking force, and the support column 38 is used to support the spring 39.

[0035] Connecting rods 32 are fixed on the outer surfaces of both sides of the first activated carbon filter 31, and mounting posts 33 are fixed on the outer surfaces of both sides of the air outlet 11. Screws 34 are threadedly connected between the connecting rods 32 and the mounting posts 33.

[0036] The connecting rod 32 is used to position and restrict the first activated carbon filter 31 inside the air vent 11. By turning the screw 34 into the connecting rod 32 and the mounting post 33, the first activated carbon filter 31 can be fixed inside the air vent 11.

[0037] The exhaust assembly also includes a duct 12, an exhaust fan 13, and a duct-type wind speed sensor 14; the duct 12 is fixed to the upper surface of the air outlet 11, the exhaust fan 13 is fixed inside one side of the duct 12, and the duct-type wind speed sensor 14 is inserted inside the top of the air outlet 11.

[0038] Air vent 11 serves as the inlet of the exhaust system, responsible for drawing exhaust gas from the coating head area into the device. Air duct 12 guides the exhaust gas out, and exhaust fan 13 provides exhaust power. Through suction, it maintains a negative pressure environment in the coating head area, ensuring timely exhaust gas discharge. Exhaust fan 13 is a variable frequency fan, which can adjust its speed to control the air volume as needed. Pipe-type wind speed sensor 14 monitors the wind speed inside air vent 11 in real time and feeds back the data to the control system. The on / off operation of exhaust fan 13 is connected to the control box, and the speed of exhaust fan 13 can be adjusted according to the data fed back by pipe-type wind speed sensor 14.

[0039] Working principle: When the air vent 11 draws in air, the first activated carbon filter 31 and the second activated carbon filter 35 filter the incoming air. When the duct-type wind speed sensor 14 detects an abnormal wind speed inside the air vent 11, the first activated carbon filter 31 and the second activated carbon filter 35 need to be replaced. When replacement is required, first unscrew the screw 34 from the mounting post 33. After the connecting rod 32 is unrestricted, the first activated carbon filter 31 can move downwards. When the first activated carbon filter 31 and the second activated carbon filter 35 are detached from the air vent 11, an inward squeezing force is applied to the movable post 391, causing the silicone post 392 to detach from the connecting frame 36, thus replacing the second activated carbon filter. Applying an upward pulling force 35 separates the first activated carbon filter 31 and the second activated carbon filter 35. Then, determine the cleanliness of the first activated carbon filter 31 and the second activated carbon filter 35, and replace the filter that needs to be replaced. Then, insert the fixing rod 37 into the inside of the connecting frame 36, apply an inward pressing force to the movable column 391, so that the spring 39 is in a compressed state. Move the support column 38 to the required height, release the force applied to the movable column 391, and under the elastic force of the spring 39, the silicone column 392 springs back into the inside of the connecting frame 36. Then, insert the first activated carbon filter 31 and the second activated carbon filter 35 into the inside of the air vent 11, and then turn the screw 34 into the inside of the mounting column 33.

[0040] This step allows for the quick removal of the double-layer filter from inside the air vent 11 and the rapid disassembly and replacement of the double-layer filter.

[0041] Please see Figures 1-3 As shown, this embodiment, based on the above embodiment, also includes an installation component. The installation component is located on the other side of the air outlet 11. The installation component includes a fixing plate 21, a limiting groove 22, a moving column 23, and a limiting plate 24. The fixing plate 21 is fixed to the outer surface of the other side of the air outlet 11. The upper surface of the fixing plate 21 is in contact with the lower surface of the duct-type wind speed sensor 14. The limiting groove 22 is opened inside the other side of the fixing plate 21. The moving column 23 is connected through the interior of the fixing plate 21. The limiting plate 24 is fixed to the upper surface of the moving column 23. The surfaces of the moving column 23 and the limiting plate 24 on one side are in contact with the outer surface of the duct-type wind speed sensor 14.

[0042] The fixed plate 21 provides a mounting base for the pipe-type wind speed sensor 14. The limiting groove 22 is used to restrict the movement of the moving column 23 within the fixed plate 21. By sliding the moving column 23 up and down within the fixed plate 21, the limiting plate 24 is driven to clamp the outer surface of the sensor, thus achieving rapid fixation.

[0043] A connecting column 25 is fixed to the lower surface of the movable column 23. A threaded column 26 is threadedly connected to the connecting column 25 and the fixing plate 21. A guide plate 27 is fixed to the lower surface of the threaded column 26.

[0044] The connecting column 25 is used to control the up and down movement of the moving column 23, the threaded column 26 is used to fix the connecting column 25 to the bottom of the fixed plate 21, and the guide plate 27 serves as the rotating handle of the threaded column 26, providing operating torque for easy manual adjustment.

[0045] Working principle: When it is necessary to fix the duct-type wind speed sensor 14 in the required position, first insert the duct-type wind speed sensor 14 into the air outlet 11 so that the outer surface of the duct-type wind speed sensor 14 is in contact with the air outlet 11. Then, apply an upward pushing force to the connecting column 25, and the moving column 23 moves upward inside the fixing plate 21. When the connecting column 25 can no longer be pushed, apply a rotational force to the guide plate 27 so that the threaded column 26 rotates into the interior of the fixing plate 21.

[0046] This step allows for quick and stable fixing of the duct-type wind speed sensor 14 in the desired position.
