 Specific usage method:
 Step one, select
 Start the first motor 10, the first motor 10 drives the variable pitch screw 3 to rotate synchronously through the outer chain 9, and the support plate 14 moves up and down synchronously under the drive of the variable pitch screw 3; because the pitch of the upper and lower ends of the variable pitch screw 3 is short , The pitch in the middle is long, the spacing between the pallets 14 will continue to change when the pallet 14 moves up and down, specifically: when the pallet 14 moves to the upper and lower ends, the spacing between the pallets 14 is small , Save the storage space of the die-cutting board. When the pallet 14 is moved to the middle position, the distance between the pallets 14 is large, and the operation space is large, which is convenient for the pick-and-place operation of the die-cutting board.
 If the die-cutting board on the pallet 14 is a non-selected die-cutting board, the first motor 10 continues to rotate to make the pallet 14 pass the middle position of the variable pitch screw 3 and enter the upper area for temporary storage, or vice versa, enter The lower area is then temporarily stored. If the die-cutting board on the pallet 14 is the selected die-cutting board, the upper plane of the pallet 14 that is loaded with the required die-cutting board moves to be flush with the fixing slot 1206 of the turnover frame 1204 In the position, the first motor 10 stops rotating.
 Step two, transfer
 Start the electric cylinder 1101, the electric cylinder 1101 drives the fixing member 1102 to the rear end; the electric push rod 1106 in the contracted state extends, so that the top plate 1105 clamps and fixes the die cutting board on the pallet 14; the electric cylinder 1101 drives the fixing member 1102 moves to the foremost end. At this time, the die-cutting board has been transferred to the fixing slot 1206 of the turning frame 1204.
 Step three, flip
 Fix the die-cutting board and the flip frame 1204 by fixing the knob B 1205; rotating the flip frame 1204 can make the front and back sides of the die-cutting board face up respectively, which is convenient for the maintenance and adjustment of the front and back sides of the die-cutting board; by fixing the knob A 1203, The rotation position of the turning frame 1204 is fixed.
 Step four, loading
 Move the device to the die-cutting board installation position of the die-cutting machine; start the second motor 19, the second motor 19 drives the inner sprocket 17 to rotate synchronously through the inner chain 16, and the lift seat 18 is driven by the inner sprocket 17 to synchronize Move down until the lifting seat 18 lifts the device to a suitable height, the second motor 19 stops rotating, and the position of the device is completely fixed; loosen the fixing knob B 1205, and push the die-cutting board on the flip frame 1204 Enter the die cutting machine to complete the installation of the die cutting board.
