[0028] Working principle: When the floor needs to be UV cured, first slide the processing table 3 to move it out of the drying box 2 from the opening, then place the floor between the plywood 19 on both sides, and drive the bidirectional screw rod 16 to rotate to one side through the motor 2 17, so that the bidirectional screw rod 16 can drive the nut seats 2 18 on both sides to approach each other, and the nut seats 2 18 on both sides can drive the plywood 19 on both sides to approach each other until the plywood 19 on both sides clamp the floor in the middle, and then turn off the motor 2 17 to make the nut seat 2 18 and the plywood 19 stay in the current position. At this time, one side of the floor will face upward, and then move the processing table 3 to enter the drying box 2 through the opening, and the side of the floor facing upward can be UV cured in the drying box 2, and the drying is completed on this side. After completion, the motor 12 drives the screw rod 11 to rotate, the screw rod 11 can drive the nut seat 13 to move, the nut seat 13 can drive the cross bar 8 and the latching tooth 9 to move, the latching tooth 9 can drive the gear 7 to rotate, and the gear 7 can drive the rotating rod to rotate after the rotation of the gear 7, and the rotating rod can drive the clamped floor to turn over through the clamping mechanism, so that the other side of the floor faces upward, and the other side is cured. The operation is convenient, and the forward and reverse rotation of the screw rod 11 can drive the nut seat 13 to reciprocate, and after the reciprocating movement of the cross bar 8, it can drive the gear 7 and the rotating rod 6 to reverse forward and reverse, and the floor is turned over, so that the floor can be dried on both sides in the drying box 2, the drying effect is better, and the efficiency of UV curing of the floor is improved.

[0029] After a batch of floors are cured, the processing table 3 is dragged again to move out of the drying box 2 from the opening, and then the two-way screw rod 16 is driven by the motor 17 to rotate in the opposite direction, driving the nut seats 18 on both sides to move away from each other, and the floor is loosened to disassemble the floor. During the movement of the processing table 3, the protrusion 20 will always be inserted in the groove 23 and move together, and the roller 21 in the moving groove will roll along the inner wall of the moving groove, making it easier for the processing table 3 to move along the groove 23 and the moving groove.
