The baking ovens currently used basically adopt air-floating baking ovens, and the pole pieces are all in a floating state in the baking oven. When the tension on the left and right sides of the pole piece is uneven, or the width of the pole ears on the left and right sides of the pole piece is inconsistent, it is easy to cause the pole piece to deviate in the baking oven. In the prior art, when encountering such a situation, a deviation correction device located behind the baking oven is usually used to solve it. However, when the pole piece deviates seriously, the effect is poor.
