[0028] The usage state of the present invention is as follows: The present invention has a reasonable and simple structure, low production cost, and convenient installation. When using this heating film punching machine, first place the heating film to be punched on the punching table 2. Subsequently, start the oil cylinder 53 in the lifting mechanism 5, and its piston rod extends, pushing the connecting seat 55 to move downward along the guide column 52 along the path defined by the guide hole 51, thereby driving the replaceable punch device 6 to move downward until the replaceable punch device 6 presses the heating film on the punching table 2. During this process, due to the elastic pad 57 (made of rubber material) between the connecting seat 55 and the end of the piston rod of the oil cylinder 53 playing a buffering role, it can effectively prevent the replaceable punch device 6 from damaging the heating film. Then, start the second motor 618 in the replaceable punch device 6. The right output shaft of the second motor 618 drives the second driving gear 617 to rotate. The second driving gear 617 drives the second driven gear 615 to rotate through the second intermediate gear 616, so as to make the transmission shaft 68 rotate. The transmission shaft 68 drives all the cams 611 fixed on it to rotate. When the cams 611 rotate, they push the pressing blocks 691 connected to them. The pressing blocks 691 push the connecting rod 695 to move outward, so that the punching head 696 extends to perform punching operations. At the same time, the pressing blocks 691 also push the clamping blocks 693 to extend. The outside of the clamping blocks 693 is T-shaped and matches the inside of the through holes 610 on the bottom plate 613. The clamping blocks 693 extend and are stuck into the through holes 610 to ensure the reliability and stability of the punching process. When it is necessary to replace different punching heads 696, first start the second motor 618 again to reverse the transmission shaft 68, drive the cams 611 to rotate in the reverse direction, and then retract the punching head 696 to the initial position. Then start the first motor 61. The left output shaft of the first motor 61 drives the first driving gear 63 to rotate. The first driving gear 63 drives the first driven gear 67 to rotate through the first intermediate gear 64, so as to make the whole rotating body 65 rotate. There are multiple transmission cavities 612 arranged horizontally inside the rotating body 65. A punch mechanism 69 is provided at the opening around each transmission cavity 612. By rotating the rotating body 65, the required punching head 696 can be rotated to the lower punching position. After that, repeat the above punching operation process to realize the switching and use of different punching heads, meet the diversified punching requirements of the heating film, and improve the punching efficiency.
