Drying oven for lithium battery coating machine and drying oven air current control method

[0030] A method for controlling the oven air flow of a lithium battery coating machine, see Figure 2 to Figure 3 shown, including

[0031] The two rows of air nozzles 2 on the top and bottom of the oven 1 respectively blow hot air to the material tape 4 in the tape running channel 3; the hot air is blown from the air nozzle 2 to dry the material tape 4;

[0032] After the air nozzle 2 blows the hot air to the surface of the strip 4, a negative pressure suction area 5 is formed between two adjacent air nozzles 2;

[0033] The negative pressure suction area 5 between two adjacent air nozzles 2 supplements air or hot air to the surface of the strip 4;

[0034] Along the width direction of the material belt 4, a high-pressure zone is formed in the middle area of ​​the material belt 4, and a low-pressure zone is formed on both sides of the material belt 4; hot air gathered in the high-pressure zone in the middle flows to the low-pressure zones on both sides respectively;

[0040] A kind of oven of lithium battery coating machine, see Figure 2 to Figure 3 As shown, it includes several sections of ovens 1, and each section of oven 1 is provided with upper and lower rows of air nozzles 2, and between the upper and lower rows of air nozzles 2 is provided with a belt-running channel 3 through which a feeding belt 4 passes. A negative pressure suction area 5 for supplementing air or hot air is arranged between the nozzles 2, and the negative pressure air suction area 5 communicates with external air or a hot air source. Negative pressure air suction ports are respectively arranged on both sides of the air nozzle 2, after the air nozzle 2 blows hot air to the surface of the material tape 4, the negative pressure air suction area 5 supplies air or hot air to the surface of the material tape 4. When hot air is blown out from the tuyere 2, a negative pressure is formed at the negative pressure suction port, and the negative pressure suction port sucks th...
