[0033] The cylinder body of the first cylinder 41 is connected to the mounting plate 20, and the inlet and outlet ports of the first cylinder 41 face the wiring hole 121 of the side plate 12. This facilitates the arrangement of the inlet pipe 411 and outlet pipe 412 of the first cylinder 41 to be short and straight, avoids right-angle bends in the pipeline, reduces airflow resistance, ensures stable pressure at the inlet of the first cylinder, and enables the cylinder to start quickly and reach the set speed.

The second cylinder 51 drives the cutting component to move from the cutting position to the avoidance position of the material placement path.

[0038] The second intake pipe and the second exhaust pipe of the second cylinder 51 are arranged in a short and straight manner to avoid right-angle bends in the pipeline, reduce airflow resistance, and ensure that the inlet of the second cylinder 51 receives stable pressure.

[0039] The material cutting device also includes two second slide rails 52 and two second sliders 53. The two second slide rails 52 are fixed on the base plate 13.

In this way, the pressure head 64 and the first cutter 31 can avoid the welding strip 1 from being laid on the top plate 11. After the welding strip 1 is laid on the top plate 11, the third cylinder 61 drives the pressure head 64 and the first cutter 31 to return to above the welding strip 1 along the M2 direction.
