It also includes a clamping mechanism for clamping the slab 5. The clamping mechanism includes clamping plates 5 symmetrically arranged on both sides of the placing area 4, and an adjusting mechanism for adjusting the relative or opposite movement of a pair of the clamping plates 5; the pre - pressing mechanism includes a pre - pressing plate 13 and a telescopic cylinder 14 for driving the pre - pressing plate 13 to move up and down. The pre - pressing plate 13 is coaxially arranged with the placing area 4.

[0026] Working principle: When the present utility model is in use, the conveying platform 3 is used to convey the slab in sequence. When the slab is conveyed to the placing area 4, the clamping plate 5 of the clamping mechanism can be used to clamp the slab, and the relative or opposite movement of the clamping plate 5 can be adaptively adjusted according to the size of the slab by using the adjusting mechanism, so that the clamping effect of the clamping plate 5 on the slab is more stable, preventing the slab from being displaced and affecting the pressing effect on the slab. Then, the telescopic cylinder 14 is used to drive the pre - pressing plate 13 to move downward to press the slab.
