Referring to fig. 7, the laminator is in a first state: the second base plate moves towards the direction close to the third base plate, so that the closing of the die cavities on the second starting plate, the second middle plate and the second end plate is realized, and the second starting plate, the second middle plate and the second end plate are used for forming a polyurethane plate; the die cavities on the first starting plate, the first middle plate and the first end plate are opened, so that the polyurethane plate is convenient to take out, and the first starting plate, the first middle plate and the first end plate are hung on the first base plate; referring to fig. 6, the laminator is in a second state: the second base plate moves towards the direction close to the first base plate, so that the closing of the die cavities on the first starting plate, the first middle plate and the first end plate is realized, and the second base plate is used for forming a polyurethane plate; and the die cavities on the second starting plate, the second middle plate and the second end plate are opened, so that the polyurethane plate is convenient to take out, and the second starting plate, the second middle plate and the second end plate are hung on the second base plate.
If the number of the first bearing plates is more than three, the load bearing burden of the first base plate is increased; if the number of the second bearing plates is more than three, the load bearing burden of the second base plate is increased; in addition, if the number of the first bearing plates between the first substrate and the second substrate is larger than three, the distance between the first substrate and the second substrate is too large, gaps are inevitably formed between the adjacent first bearing plates after pressing, error accumulation is caused by accumulation of a plurality of gaps, one or more layers of cavities cannot be closed, and energy is wasted. Similarly, if the number of the second bearing plates between the second substrate and the third substrate is larger than three, the distance between the second substrate and the third substrate is too large, gaps are inevitably formed between the adjacent second bearing plates after pressing, and a plurality of gaps are accumulated to cause error accumulation, so that one or more layers of cavities cannot be closed, and energy is wasted.

The lifting distance of the output platform is determined by the number of turns of the screw rod, so that the lifting distance of the output platform can be limited by controlling the number of turns of the screw rod, and the fine adjustment of the lifting distance of the output platform is realized; in addition, because the screw nut is used for replacing the hydraulic cylinder, potential safety hazards caused by leakage of hydraulic oil of the hydraulic cylinder are avoided.
