The drawer-type air knife is used in the drying equipment, and the infrared heating plate is integrated on the air knife, so that the air outlet nozzle and the infrared heating plate are installed in an integrated manner, which prevents the installation space of the infrared heating plate from being occupied when the corresponding structure of the air outlet nozzle is installed separately, which is beneficial to improving the installation density of the infrared heating plate, and further beneficial to improving the baking efficiency of the drawer-type air knife on the coated electrode; please refer to the following embodiments for details.

[0058] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In the first embodiment of the present application, a drawer-type air knife 10 is provided for baking coated electrodes. The air knife 10 includes a mounting body 11, an infrared heating plate 12 and a packaging member 13; an air inlet 111 is provided at the bottom end of the mounting body 11, and air outlets 112 are provided on both sides of the width direction of the top of the mounting body 11, respectively, and the air inlet 111 is connected to the two air outlets 112; a mounting groove 113 is provided on the top surface of the mounting body 11, and the mounting groove 113 is located between the two air outlets 112; the inner wall of the mounting groove 113 is provided with a Two symmetrically distributed card slots 114, the two card slots 114 are respectively located on the opposite side of the two air outlet nozzles 112; the two card slots 114 and the same end of the installation slot 113 along the length direction are both set through the first side 115 of the installation body 11; the two ends of the infrared heating plate 12 are respectively inserted into the two card slots 114; the packaging component 13 is detachably connected to the first side 115 of the installation body 11, and is covered at the same end of the two card slots 114 and the installation slot 113 that pass through the first side 115 of the installation body 11.

[0059] It can be understood that the drawer-type air knife 10 provided in the present application is used in a drying equipment, and the infrared heating plate 12 is integrated on the air knife 10, so as to realize the integrated installation of the air outlet nozzle 112 and the infrared heating plate 12, thereby preventing the corresponding structure of the air outlet nozzle 112 from occupying the installation space of the infrared heating plate 12 when it is installed separately, which is beneficial to improve the installation density of the infrared heating plate 12, and further beneficial to improve the baking efficiency of the drawer-type air knife 10 for the coated electrode.

[0060] The installation body 11 is installed on the drying equipment and is used to fix the infrared heating plate 12; the top surface of the installation body 11 is provided with an installation groove 113, and the inner wall of the installation groove 113 is provided with two symmetrically distributed card grooves 114, and the two ends of the infrared heating plate 12 are respectively inserted into the two card grooves 114, and the two card grooves 114 restrict and fix the infrared heating plate 12 on the installation body 11, and the installation groove 113 forms an opening on the top surface of the installation body 11, so that the radiated heat of the infrared heating plate 12 can be dissipated, so as to achieve the baking effect on the coated electrode. The two card grooves 114 and the same end of the installation groove 113 along the length direction are all set through the first side 115 of the installation body 11, so that the infrared heating plate 12 can be inserted into the two card grooves 114 from the first side 115 of the installation body 11, so as to achieve the drawer-type installation of the infrared heating plate 12, which is convenient for installation. The packaging component 13 is detachably connected to the first side 115 of the installation body 11, and is covered at the same end of the two card slots 114 and the installation slot 113 that penetrate the first side 115 of the installation body 11, thereby closing the openings of the two card slots 114 and the installation slot 113 at the same end along the length direction, preventing the infrared heating plate 12 from escaping from the card slots 114. The detachable installation method of the packaging component 13 is convenient for installation and disassembly, and is convenient for installation, disassembly and replacement of the infrared heating plate 12.

[0061] Air outlets 112 are provided on both sides of the top of the installation body 11. The air outlets 112 are slit-shaped and usually face the coated electrode. An air inlet 111 is provided at the bottom of the installation body 11. The air inlet 111 is connected to the two air outlets 112. A sealing strip 14 is provided at the bottom of the installation body 11. The sealing strip 14 is arranged around the air inlet 111 to improve the sealing of the air inlet 111 when the installation body 11 is installed in the drying equipment to prevent air leakage. When the installation body 11 is installed in the drying equipment for use, the air inlet 111 is connected to the air inlet on the drying equipment, so that the airflow enters the installation body 11 from the air inlet 111 and flows out from the air outlet 112 to blow toward the coated electrode to blow away the solvent and moisture on the coated electrode to improve the baking efficiency; the wind acts on the coated electrode to form a suspension effect on the coated electrode. The top surface of the infrared heating plate 12 is a heating surface 121 . When the wind knife 10 bakes the coated electrode, the heating surface 121 faces the coated electrode. The mounting slot 113 is located between the two air outlet nozzles 112, and the two card slots 114 are respectively located on the opposite side of the two air outlet nozzles 112. The two ends of the infrared heating plate 12 are respectively inserted into the two card slots 114 to fix the infrared heating plate 12 between the two air outlet nozzles 112. The airflow blown out by the air outlet nozzle 112 has a diffusion effect on the radiant heat of the infrared heating plate 12, which is beneficial to the uniform and rapid diffusion of heat, promotes the rapid drying of the coated electrode, and improves the baking efficiency; the air outlet nozzle 112 can be at a certain inclination angle relative to the coated electrode, and the two air outlet nozzles 112 are symmetrically distributed relative to the coated electrode, and the two air outlet nozzles 112 are inclined to the middle position, so that the airflow blown out by the two air outlet nozzles 112 acts evenly on the coated electrode, which is beneficial to keep the coated electrode stable and avoid the coated electrode from deviating from the infrared heating plate 12, thereby ensuring the baking effect of the infrared heating plate 12.

[0062] The traditional wind knife only has the function of blowing and suspending. The drawer-type wind knife 10 provided in this application integrates the functions of blowing and suspending and infrared heating. It does not require an additional installation space for the infrared heating plate 12, which is conducive to reducing the cost of equipment materials and reducing space occupancy. A wire outlet hole 131 can be opened on the package 13 and / or the installation body 11 to facilitate the high-temperature wiring of the infrared heating plate 12 to be led out and connected to an external power supply. The infrared heating plate 12 generates infrared rays after being powered on, radiates heat, and bakes the coated electrode; infrared radiation is divided into three bands: near (short wave) infrared radiation (wavelength ≤ 2μm), medium (medium wave) infrared radiation (wavelength 2μm~4μm) and far (long wave) infrared radiation (wavelength>4μm), which can be selected according to actual needs.

[0063] Please continue reading Figure 1 , Figure 2 and Figure 3 In some embodiments, the wind knife 10 includes one or more infrared heating plates 12; wherein the plurality of infrared heating plates 12 are sequentially arranged between two air outlets 112 along the length direction.

[0064] It can be understood that the wind knife 10 can use one or more infrared heating plates 12 as needed. For example, when the baking area is small, one infrared heating plate 12 can meet the baking area requirement. When the baking area is large, multiple infrared heating plates 12 are spliced ​​together to meet the baking area requirement. Multiple infrared heating plates 12 are arranged in sequence between two air outlets 112 along the length direction, that is, multiple infrared heating plates 12 are spliced ​​together one by one along the length direction, so as to realize direct baking of the coated electrodes of the lithium battery.

[0065] Please refer to Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14 In some embodiments, the mounting body 11 includes a first mounting seat 116 and a second mounting seat 117; the bottom end of the first mounting seat 116 is opened; the two air outlets 112 are located on both sides of the top of the first mounting seat 116; the top of the second mounting seat 117 is inserted into the bottom end opening of the first mounting seat 116, and is detachably connected to the first mounting seat 116; the air inlet 111 is located at the bottom end of the second mounting seat 117.

[0066] It can be understood that the installation body 11 is split into a first installation seat 116 and a second installation seat 117 to facilitate production and manufacturing; the second installation seat 117 is detachably connected to the first installation seat 116 to facilitate assembly; the bottom end of the second installation seat 117 is installed at the air inlet of the drying equipment, so that the air inlet is connected to the air inlet 111; the top of the first installation seat 116 is provided with two air outlet nozzles 112, which have a suspension effect on the coated electrode, and can blow away the solvent and moisture on the coated electrode, thereby improving the baking efficiency.

[0067] Please continue to refer to Fig. 9 and Fig.10 In some embodiments, the first mounting seat 116 includes two insulating blocks 1161 , and the two card slots 114 are respectively located on opposite sides of the two insulating blocks 1161 .

[0068] It can be understood that the two card slots 114 are respectively located on the two insulating card blocks 1161, so that the two insulating card blocks 1161 fix the infrared heating plate 12. Since the infrared heating plate 12 radiates heat when it is continuously used, forming a high temperature environment, the frame structure of the first mounting seat 116 is usually made of metal material, and the insulating card blocks 1161 are used. The insulating characteristics of the insulating card blocks 1161 can separate the infrared heating plate 12 from the metal frame structure, which is beneficial to prevent the infrared heating plate 12 from being electrically shorted with the metal frame structure, and effectively ensure the service life of the wind knife 10.

[0069] In some embodiments, the insulating card block 1161 is configured as a mica insulating card block.

[0070] It can be understood that the insulating card block 1161 is made of mica material, so that the insulating card block 1161 has excellent high temperature resistance, which can prevent the high temperature environment generated when the infrared heating plate 12 is used for a long time from causing the insulating card block 1161 to melt; the mica material also has electrical insulation and mechanical strength, which improves durability, so that the insulating card block 1161 can insulate and separate the infrared heating plate 12 from the metal frame structure, thereby preventing the infrared heating plate 12 from being short-circuited.

[0071] Please continue to refer to Figure 7 , Figure 8 , Fig. 9 and Fig.10 In some embodiments, the first mounting seat 116 further includes an outer frame 1162 and a support plate 1163; the outer frame 1162 encloses a ventilation cavity 1164 that is arranged along the height direction; the support plate 1163 is located in the ventilation cavity 1164, and the support plate 1163 fixes the outer frame 1162 at both ends along the length direction, and the two ends of the support plate 1163 in the width direction are spaced from the outer frame 1162; the two insulating blocks 1161 are respectively located at both ends of the support plate 1163 in the width direction, and the two insulating blocks 1161 and the outer frame 1162 respectively enclose the two air outlets 112.

[0072] It can be understood that the outer frame 1162 is surrounded to form a ventilation cavity 1164 that is connected from top to bottom, and the bottom end of the ventilation cavity 1164 is connected to the air inlet 111. One end of the outer frame 1162 along the length direction is closed, and can be sealed by welding the entire surface; the other end of the outer frame 1162 along the length direction (i.e., the first side 115) is open and detachably connected to the packaging member 13, so that the infrared heating plate 12 can be easily installed and removed from the opening. The support plate 1163 is installed in the ventilation cavity 1164. The support plate 1163 is located at both ends of the length direction to fix the outer frame 1162. The support plate 1163 is located at both ends of the width direction to form a gap with the inner wall of the ventilation cavity 1164 to allow air flow to flow through. The support plate 1163 is used to fix two insulating blocks 1161. The two insulating blocks 1161 are respectively located at both ends of the width direction of the top surface of the support plate 1163. The two insulating blocks 1161 and the outer frame 1162 are respectively enclosed to form two air outlets 112, so that the air inlet 111 enters The airflow flows into the outer frame 1162 through the bottom end of the ventilation cavity 1164, and then flows out from between the two insulating blocks 1161 and the outer frame 1162; the first mounting seat 116 adopts a split structure of the outer frame 1162, the support plate 1163 and the two insulating blocks 1161, which is easy to produce and reduces the difficulty of production. The insulating block 1161 serves as a structural component of the air outlet 112 and a fixing component of the infrared heating plate 12, which reduces the number of parts of the first mounting seat 116, which is conducive to reducing the difficulty of assembling the first mounting seat 116.

[0073] Please continue to refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Fig.11 In some embodiments, the first mounting seat 116 or the second mounting seat 117 is provided with a waist hole 1181 extending along the height direction, and the second mounting seat 117 or the first mounting seat 116 is detachably connected to the waist hole 1181; the connection position of the second mounting seat 117 or the first mounting seat 116 is moved along the waist hole 1181 to adjust the relative height of the air outlet 112 and the air inlet 111.

Since the top end of the second mounting seat 117 is inserted into the bottom opening of the first mounting seat 116, the waist hole 1181 is located on the first mounting seat 116, which is convenient for the user to directly observe during installation; when the waist hole 1181 is located on the first mounting seat 116 or the second mounting seat 117, a fixing hole 1182 is provided on the second mounting seat 117 or the first mounting seat 116, and the first mounting seat 116 and the second mounting seat 117 are detachably connected through the waist hole 1181 and the fixing hole 1182. The connection method can adopt a bolt or a snap-on structure, which is convenient for disassembly and assembly and convenient for adjusting the connection position. The waist hole 1181 extends in the height direction, and the connection position of the second mounting seat 117 or the first mounting seat 116 can be moved along the waist hole 1181, that is, the first mounting seat 116 can adjust the height relative to the second mounting seat 117, so as to adjust the relative height of the air outlet 112 and the infrared heating plate 12 on the first mounting seat 116 and the air inlet 111 on the second mounting seat 117. When the second mounting seat 117 is installed on the drying equipment, the installation height of the air outlet 112 and the infrared heating plate 12 on the first mounting seat 116 can be adjusted through the waist hole 1181, so that the air outlet 112 and the infrared heating plate 12 can be adjusted to a better position relative to the coated electrode, thereby improving the baking efficiency of the coated electrode and making the air knife 10 suitable for drying coated electrodes of different specifications.

[0078] It can be understood that the wind uniformity plate 1171 is located at the top of the second mounting seat 117, and the wind uniformity plate 1171 is evenly arranged with multiple wind uniformity holes 1172, which has the effect of uniformly dispersing the airflow, improving the uniformity of the airflow flowing out of the two air outlets 112, and promoting the airflow to act evenly on the coated electrode, blowing away the solvent and moisture on the coated electrode, which is beneficial to improving the drying efficiency of the coated electrode, and at the same time ensuring that the coated electrode maintains balance under the suspension effect of the airflow flowing out of the two air outlets 112, preventing the coated electrode from deviating from the infrared heating plate 12, thereby ensuring the drying effect of the infrared heating plate 12 on the coated electrode.
