Process for pasting film and covering, spraying and stacking sand in multiple layers

The invention relates to the technical field of sand blasting, and discloses a film-pasting multi-layer sand blasting covering and stacking process which uses sand blasting equipment and comprises a working table, a second symmetric block, a third symmetric block and a side plate are connected to the working table, a pressure roller is connected to the second symmetric block, a cross rod is connected to the third symmetric block, a sleeve is slidably connected to the cross rod, and a pressure roller is connected to the side plate. The two ends of the sleeve are connected with film winding wheels, the side plates are connected with balance rods in a sliding mode, one ends of the balance rods are connected with clamping strips, the clamping strips are connected with connecting rods, the connecting rods are sleeved with clamping springs, and the clamping springs are fixedly connected between the clamping strips. A protective film is firmly pressed and attached to the surface of a shell through a pressure roller
