The first material blocking module 24 includes a mounting plate 241, a support seat 242 and a material blocking plate 243. The mounting plate 241 is arranged on the upper surface of the first rack 233, and the bottom surface of the mounting plate 241 is connected to the first slider 222.

[0034] Subsequently, when the driving motor 231 drives the rotating gear 232 to rotate counterclockwise, it can drive the first rack 233 and the second rack 234 to move inward. When the first rack 233 and the second rack 234 move inward, they can drive the first blocking module 24 and the second blocking module 25 to move inward, thereby realizing the contraction of the first blocking module 24 and the second blocking module 25, so as to center and limit the circuit board placed on the feeding roller 9 on both sides.
