Corresponding upper guide grooves 300 and lower guide grooves 301 are respectively arranged through the upper guide plate 3 and the lower guide plate 30. The upper guide grooves 300 and the lower guide grooves 301 are arranged in a matching manner with the punching groove cutter 20.

[0019] The working principle is as follows. During feeding, the bobbin to be punched with grooves is placed on the top of the backing plate 6. The pressing plate 70 is driven by the clamping cylinder 7 to move downward to press the bobbin on the backing plate 6. Then, the backing plate 6 is driven by the X-axis linear driving mechanism 5 to move towards the punching groove mechanism side. When the position of the bobbin to be punched with grooves is aligned with the punching groove cutter 20, the punching groove driving cylinder 2 drives the punching groove cutter 20 to move downward. The punching groove cutter 20 will move along the upper guide grooves 300 and the lower guide grooves 301, and grooves are punched on the bobbin. By driving the bobbin to move forward step by step, continuous punching groove operations can be carried out on the bobbin, effectively improving the processing efficiency, increasing the output, reducing the labor input, lowering the production cost, and improving the processing quality of the product.
