[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: Reference Figure 1-5 The die-cutting machine tool changing mechanism shown includes a support frame 1, a rectangular frame 2 and a fixed unit. The rectangular frame 2 is installed at the upper end of the support frame 1. The fixed unit includes a moving frame 3 and a flip frame 4. The moving frame 3 is horizontally slidably installed at the upper end of the rectangular frame 2. Specifically, the lower end of the moving frame 3 is integrated with a T-shaped slider 301, and the upper end of the rectangular frame 2 is provided with a T-shaped slide groove 201 for the T-shaped slider 301 to slide horizontally.

[0026] The flip frame 4 is located on the upper side of the moving frame 3 and is hinged to the moving frame 3. A fixing structure 1 for fixing the knife plate is installed on the peripheral side of the flip frame 4. Specifically, the fixing structure 1 includes a fixed slider 5 and a first fixed stud 6. The side end of the flip frame 4 is provided with a limiting slide groove 402 for the horizontal sliding of the fixed slider 5. The first fixed stud 6 is rotatably installed on the outer end of the flip frame 4 and is threaded through the fixed slider 5. The lower end of the fixed slider 5 away from the first fixed stud 6 is set as an inclined surface for pressing against the knife plate, thereby fixing the knife plate to the inner side of the flip frame 4.

[0027] A relatively fixed fixing structure 2 is provided between the end of the moving frame 3 away from its hinged end and the flip frame 4. Specifically, the fixing structure 2 includes an L-shaped fixing block 7 and a second fixing stud 8. The L-shaped fixing block 7 is fixed to the side end of the moving frame 3. The second fixing stud 8 is threaded through the L-shaped fixing block 7 and abuts against the side end of the flip frame 4.

[0028] Among them, the inner side of the upper end of the turning frame 4 is provided with a limiting step 401 for the knife plate to be placed, so as to facilitate the placement of the knife plate.

[0029] Among them, a material receiving plate 9 is provided on the lower side of the rectangular frame 2, and the material receiving plate 9 is fixed on the inner side of the support frame 1. The material receiving plate 9 is inclined, and the downward inclined end of the material receiving plate 9 extends to the outside of the vertical projection of the rectangular frame 2. When the back of the knife plate is knocked, the tool accidentally falling off from the front of the knife plate will fall on the material receiving plate 9 and slide along the surface of the material receiving plate 9 to the downward inclined side of the material receiving plate 9, which is convenient for the staff to pick up.

[0030] The working principle of the present invention is as follows: when changing the knife, the knife plate with the knife installed is placed on the limit step 401 on the inner side of the flip frame 4, and then the first fixing stud 6 is manually rotated so that the inclined surface of the fixed slider 5 is pressed against the knife plate, thereby fixing the knife plate on the inner side of the flip frame 4. The knife plate can be flipped by using the flip frame 4, and the dust attached to the front and back of the knife plate can be sucked away by using a dust suction device. Then, the flip frame 4 is flipped over so that the back of the knife plate faces upward, and a professional tool such as a leather hammer is used to knock on the back of the knife plate to loosen the knife on the knife plate. Then, the flip frame 4 is flipped over so that the front of the knife plate faces upward, and the knife is pulled out outward with needle-nosed pliers or a knife puller. After the tool is disassembled, the movable frame 3 is horizontally slid to the other side of the rectangular frame 2 to install the knife.
