Problems solved by technology
[0002] In the battery production process, the pole piece drying is very critical. At present, the oven achieves the purpose of drying by heating the box and charging and discharging nitrogen. There are only a few air source outlets on both sides of each layer of oven, and the air volume is concentrated; this air source is harmful to the battery. Coil drying has little effect, but it is very easy to blow over the laminated pole pieces, resulting in damage to the pole pieces and waste, and it also causes inconvenience to the entire work of the assembly section. During battery production, the water content of the pole pieces seriously affects the battery capacity. , circulation, safety and other performances, pole piece drying is a key link in battery production
At present, ovens are common: 1. Single air outlet, concentrated air volume, large air flow during inflation and exhaust, easy to blow pole pieces
2. Uneven air flow in the box can easily cause uneven drying of the pole piece

Embodiment Construction
[0014] The present invention includes a box body 1, an oven air source 2, a main ventilation screen 3, an auxiliary ventilation screen 4, the main ventilation screen 3 is connected to the oven air source 2, and the auxiliary ventilation screen 4 is covered on the main ventilation screen 3, and can be freely rotated and twisted , main ventilating screen 3 is punched with main ventilating hole 5, and auxiliary ventilating screen 4 is punched with auxiliary ventilating hole 6; Smaller and smaller; the size of the auxiliary ventilation holes 6 is different, and the auxiliary ventilation holes are getting smaller and smaller as the concave degree of the auxiliary ventilation screen 4 changes.
[0015] When the auxiliary ventilation screen 4 on the above-mentioned main ventilation screen 3 can rotate freely to a certain position, the main ventilation hole 5 and the auxiliary ventilation hole 6 are overlapped.
[0016] The above-mentioned main ventilation screen 3 is connected to the...

The invention relates to drying equipment, in particular to a drying oven for a battery pole piece. The drying oven comprises an oven body and a drying oven air source, and the drying oven is characterized by further comprising a main ventilation screen and an auxiliary ventilation screen. The main ventilation screen is connected with the drying oven air source, the auxiliary ventilation screen covers the main ventilation screen and can be freely rotated and twisted, small main ventilation holes are formed in the main ventilation screen, and small auxiliary ventilation holes are formed in the auxiliary ventilation screen. The drying oven has the advantages of being capable of dispersing airflow, reducing air pressure and avoiding damage caused by the fact that the battery pole piece is blown in a mess. The sizes of the holes can be changed through rotation, the airflow in the drying oven can be further changed, the airflow in the drying oven is balanced, and the surface of a part cannot be scratched. The drying oven is ingenious in structure and convenient to use.
