Then, the second cylinder 43 drives the first clamping block 42 to move close to the stop block 21 to clamp the two sides of the sagger 6. The fourth cylinder 47 drives the third clamping block 45 to move close to the second clamping block 44 to clamp the other two sides of the sagger 6. Thus, the sagger 6 can be precisely positioned to ensure that the inside of the sagger 6 is aligned with the cutting assembly 52 and the stripping assembly.

[0059] In some preferred embodiments, the second power member 32 is a worm gear elevator. The worm gear elevator has strong bearing capacity, large transmission, stable transmission and self-locking function, which greatly improves the stability of the lifting plate 31 during lifting.

When the lifting plate 31 is lifted or lowered, the lifting plate 31 drives the plurality of guide rods 351 to be lifted or lowered. The plurality of guide rods 351 respectively slide on the inner walls of the plurality of guide sleeves. Thus, the lifting plate 31 can be vertically guided to improve the stability of the lifting plate 31 during lifting.
