Paper materials are easily recyclable and biodegradable, meeting environmental standards. A die-cutting machine is a device specifically designed for cutting and forming flexible materials such as paper, plastic, leather, and cloth. It uses a pre-set die (template) to precisely cut, stamp, and creasing the material to create a product of a specific shape and size. Die-cutting machines are widely used in industries such as packaging, printing, labeling, footwear, apparel, and electronics.

[0003] The Chinese utility model patent with authorization announcement number CN214988909U discloses a skew adjustment mechanism for a paper tray of a die-cutting machine.

[0022] In the specific implementation process, Figures 1 to 4 As shown, the die-cutting machine paper tray adjustment mechanism provided by the present invention includes a paper tray installed between the left side plate 1 and the right side plate 2 of the die-cutting machine housing, and a crossbeam 3 is fixed between the left side plate 1 and the right side plate 2. The crossbeam 3 is arranged on the rear side of the rear edge of the paper tray. At least one positioning member is provided on the paper tray, and a limiting member is provided on the crossbeam 3. The positioning member passes through the inner wall of the limiting member.

[0023] The paper tray includes a support plate 4, two reinforcing ribs 5 symmetrically fixed to the bottom of the support plate 4, and a cross bar 6 fixed to the rear end of the two reinforcing ribs 5. The left side plate 1 and the right side plate 2 are both provided with a first slide groove for inserting the end of the cross bar 6, and the extension direction of the first slide groove is parallel to the inclination direction of the support plate 4.

[0024] The support plate 4 is used to carry paper to ensure that the paper is flat during the die-cutting process. The reinforcing ribs 5 are symmetrically fixed to the bottom of the support plate 4 to increase the rigidity and stability of the support plate 4 and prevent the support plate 4 from deformation. The cross bar 6 is fixed to the rear end of the two reinforcing ribs 5 to connect the support plate 4 and the cross beam 3. A positioning rod 7 is fixed on the cross bar 6. The cross beam 3 is fixed between the left plate 1 and the right plate 2 of the die-cutting machine housing, and is located behind the rear edge of the paper tray.

[0025] The positioning member includes a positioning rod 7 , one end of which is fixedly connected to the outer surface of the crossbar 6 , and a plurality of positioning blocks 8 are fixedly connected to one side of the positioning rod 7 at equal intervals.

[0026] The limiting part includes a connecting frame 9, and an extrusion block 10 is slidably provided on the inner wall of the connecting frame 9. A plurality of embedded blocks 11 are fixed on one side of the extrusion block 10. The embedded block 11 can be fitted between two adjacent positioning blocks 8. The end of the extrusion block 10 away from the embedded block 11 is rotatably connected to a threaded rod 12, and one end of the threaded rod 12 extends out of the connecting frame 9. A threaded groove and a movable slide groove are provided on the inner wall of the connecting frame 9. The extrusion block 10 is slidably connected to the inner wall of the movable slide groove, and the threaded rod 12 is threadedly connected to the inner wall of the threaded groove.

[0027] The cross-sectional shape of the embedded block 11 matches the cross-sectional shape of the positioning block 8 , and can be tightly fitted when the embedded block 11 extends between two adjacent positioning blocks 8 .

[0028] The working principle provided by the present invention is as follows: when the present invention is implemented, the threaded rod 12 is rotated to disengage the embedded block 11 of the extrusion block 10 from the positioning block 8 of the positioning rod 7, thereby releasing the fixation of the positioning rod 7, and manually moving the cross bar 6 to change the distance between the cross bar 6 and the crossbeam 3, thereby adjusting the inclination angle of the support plate 4. After adjusting to the appropriate position, the threaded rod 12 is rotated in the opposite direction to re-attach the embedded block 11 of the extrusion block 10 between the two adjacent positioning blocks 8, fixing the position of the positioning rod 7, and the cross bar 6 moves along the first slide groove when moving, ensuring that the support plate 4 moves smoothly during the adjustment process, and the pin shaft at the front end of the reinforcing rib 5 moves along the second slide groove, further ensuring the stability and adjustment accuracy of the support plate 4.
