At the bottom of the first tool holder mounting table 201, a first tool holder 204 is fixedly installed. At the bottom of the first tool holder 204, a first hot cutting knife 205 is fixedly installed. The first cutting knife cylinder 2 can drive the first hot cutting knife 205 to move up and down.

[0026] The workbench 6 includes a head end table 601 and a tail end table 602. The bottoms of the head end table 601 and the tail end table 602 are fixedly installed at the front top of the base 101 through table top support columns 603.

[0027] Such as Figures 1-3 , at the four corners of the bottom of the cylinder mounting table 3, it is fixedly installed on the top of the base 101 through columns 301. And the cylinder mounting table 3 is located between the end table 201 and the tail end table 602. At the same time, at the center of the bottom of the cylinder mounting table 3, a second cutting knife cylinder 3 is fixedly installed. The output shaft of the second cutting knife cylinder 3 passes upward through the cylinder mounting table 3 and is fixedly connected to a second tool holder mounting table 302. Vertically downward, front and back, on the bottom of the second tool holder mounting table 302, second linear guide shafts 303 are fixedly installed. The second linear guide shafts 303 pass through the second tool holder mounting table 302 and are slidably connected to the second tool holder mounting table 302 through second linear bearings 304. On the top of the second tool holder mounting table 302, a second tool holder 305 is fixedly installed. On the top of the second tool holder 305, a second hot cutting knife 306 is fixedly installed. The second hot cutting knife 306 is located between the head end table 601 and the tail end table 602. The second cutting knife cylinder 3 can drive the second hot cutting knife 306 to move up and down.

[0028] At the same time, on the inner sides of the head end table 601 and the tail end table 602, there are abutting parts 604 extending inwards. When the second cutting knife cylinder 3 drives the second hot cutting knife 306 to move up to the highest point, the second tool holder mounting table 302 abuts against the abutting part 604.

[0029] At the same time, in this solution, on the left and right sides of the first tool holder mounting table 201, a feeding auxiliary component 4 and a discharging auxiliary component 5 are respectively arranged.
