Embodiment approach
[0027]As an embodiment of the present invention, the side wall of the No. 1 block 541 away from the tapered block 554 and the side wall of the No. 2 block 542 away from the tapered block 554 are both provided with arc-shaped chamfers, thereby avoiding wrapping paper Creases appear on the surface after heating; during work, during the rotation of the printing wheel 42 and the drying wheel 43, the cam 52 is driven to rotate, and the cam 52 makes the hinge plate 53 move up and down along with the cam 52 when the cam 52 rotates. Since the bottom end of the ejector rod 55 is slidably connected in the No. 2 chute 531, the cam 52 drives the ejector rod 55 to reciprocate up and down. When the ejector rod 55 slides upwards in the fixed box 34, the heating block 54 is pushed out of the No. 1 chute first. chute 32, and as the push rod 55 continues to slide, the conical block 554 produces a pressing force on the No. 1 block 541 and the No. 2 block 542, thereby pushing the No. 1 block 541 a...
