The pole piece is dried, wherein the air inlet includes a first air inlet and a second air inlet, and the first air inlet and the second air inlet are respectively located on two sides of the pole piece.

In order to make the hot air entering the box be blown to the position of the pole piece more accurately, a first blowing nozzle and a second blowing nozzle can be respectively arranged on both sides of the pole piece in the box, and the first blowing nozzle and the The first air inlet is connected; the second blowing nozzle is connected with the second air inlet. After flowing through the air inlet, the hot air enters the blowing nozzle, and blows to both sides of the pole piece through the blowing nozzle.

During the drying process, due to the evaporation of the liquid on the pole pieces, the air humidity in the box will gradually increase and affect the drying effect. part of the air out. There may be multiple air outlets, which are respectively located on both sides of the pole piece in the box.

Further, in order to prevent the air in the box from being partially discharged and the air volume and air pressure drop from affecting the drying effect, the aforementioned box can also include an air supply pipe, one end of which is connected to the circulating air pipe, and the other end is connected to the circulating air pipe. The atmosphere is connected. It is used to replenish part of the air from the atmosphere into the circulating air duct, and enter the box after being heated together with the air from the air outlet.

The utility model also provides a pole piece coating equipment, which includes any one of the aforementioned ovens.

The utility model is equipped with air inlets on both sides of the oven, adopts a simple structure to simultaneously blow hot air to both sides of the pole piece, and simultaneously dry both sides of the pole piece, so compared with the prior art, it has better drying effect, The beneficial effect of high work efficiency.

Description of drawings

The accompanying drawing is a schematic diagram of the oven of the pole piece coating equipment according to the specific embodiment of the present invention.

Detailed ways

As shown in the accompanying drawings, the oven for the pole piece coating equipment of this specific embodiment includes a rectangular box 8, and the upper side of the box 8 is provided with a first air inlet 11, a first air outlet 31 and a first air outlet. Blowing nozzle 21; Casing body 8 lower side is provided with the second air inlet 12, the second exhaust outlet 32 and the second blowing nozzle 22; The pipe 42 is connected to the heater 7, and is respectively used to introduce the air heated by the heater 7 into the first blowing nozzle 21 and the second blowing nozzle 22, and the first air outlet 31 and the second air outlet 32 communicate with the box body 8 The interior and the atmosphere are used to discharge part of the air in the box 8 (in practice, multiple air outlets can be set according to the length of the box and the use environment of the oven). Set up exhaust fans. The oven box body of this embodiment is also provided with an air outlet 53, and the air outlet 53 is connected with the air inlet end of the circulating air duct 6 through the air outlet pipe 51, and the air inlet end of the circulating air duct 6 is also connected with the air supply duct 52. Atmospheric connection, the air outlet end of the circulating air duct 6 is connected with the heater 7. The heater 7 of this specific embodiment includes a heating device and a fan.

During work, the pole piece 9 is located in the middle of the box body 8, the heating device of the heater 7 and the fan start to work, and under the power of the fan, part of the air in the box body 8 and part of the air supplemented from the atmosphere pass through the air outlet respectively.
