[0002] In the current cardboard printing and processing process, embossing and die-cutting are set as two processes for processing. However, the processing time is long, the production efficiency is low, and the product quality is easily affected during the turnover process. In addition, since the embossing edge is too close to the creasing plate and the height difference is insufficient, a folding edge cannot be formed during forming, which is not convenient for the cardboard to be folded during packaging, and the folding is prone to be uneven.

[0021] As shown in Figure 1 and Figure 2 , the utility model includes an upper template 1 and a lower template 2. At least one forming group is provided on the upper template 1. Each forming group includes a die-cutting plate 10 fixedly arranged on one side of the upper template 1, a connecting frame 12 movably arranged on the other side, an indentation plate 31 detachably arranged on one side of the connecting frame 12, and an embossing plate 32 movably arranged on the other side. An arc section 311 with a narrow inner part and a wide outer part is provided on one side of the indentation plate 31, and the narrow inner position of the arc section 311 protrudes from one side of the embossing plate 32; A support plate 21 is provided on the lower template 2, a groove 210 is provided at a position corresponding to the embossing plate 32 on the support plate 21, a fixed block 22 is provided in the groove 210, a boss 221 is provided on the fixed block 22 at a position corresponding to the embossing plate 32, and a cavity structure for the die-cutting plate 10 to extend into is formed by surrounding between the outer side wall of the fixed block 22 and the groove wall of the groove 210.

[0022] Specifically, a connecting plate 13 is fixedly arranged at the lower end of the upper template 1. Two die-cutting plates 10 vertically extending downward are symmetrically arranged on the connecting plate 13. One end of a first compression spring 41 is fixedly connected to a position corresponding to the space between the two die-cutting plates 10 on the connecting plate 13, and the other end of the first compression spring 41 is fixedly connected to the connecting frame 12.

[0023] The cross-section of the connecting frame 12 is a rectangular frame structure with an opening downward, and the outer side wall of the corresponding end of the rectangular frame structure is attached to the inner side wall of the die-cutting plate 10; A section of inclined blade surface 101 with a wide upper part and a narrow lower part is provided on the outer side wall of the die-cutting plate 10.

[0024] Two indentation plates 31 are symmetrically screwed and fixed on the end surface of the opening end of the cross-section of the connecting frame 12. The arc sections 311 on the two indentation plates 31 face each other and enclose a flared shape with an opening downward in cross-section.

[0025] The upper part of the connecting frame 12 is fixedly connected to one end of the second compression spring 42, and the other end of the second compression spring 42 is fixedly connected to the embossing plate 32.

[0026] At a position on the fixed block 22 corresponding to the arc segment 311, a matching rounded corner segment 222 is provided. The height difference between the upper end surface of the boss 221 and the plane where the higher end of the rounded corner segment 222 is located is 1 mm. During processing, the outer side walls of the arc segment 311 and the rounded corner segment 222 are respectively pressed against the upper and lower end surfaces of the cardboard, so as to achieve the purpose of embossing and bending the edge of the cardboard.

[0027] The working principle of the present utility model is as follows:

[0028] As Figures 1 to 2 shown, before processing, according to the indentation requirements of the cardboard, corresponding indentation plates are symmetrically screwed on the left and right sides of the bottom end of the connecting frame 12. The arc segments 311 on the two indentation plates 31 face each other and enclose a flared shape with an open bottom. At the same time, the embossing plate 32 is set to protrude downward from the bottom of the flared shape, that is, at the narrow position inside the arc segment 311 (as Figure 2 shown in the position state).

[0029] During processing, the cardboard is placed on the fixed block 22 of the lower template 2. The upper template 1 moves downward towards the lower template 2. Due to the protrusion of the embossing plate 32, first, the lower end surface of the embossing plate 32 and the upper end surface of the boss 221 simultaneously press the cardboard tightly. The upper template 1 continues to move downward and drives the indentation plate 31 to continue to move downward with the connecting frame 12 and squeeze the second compression spring 42 to maintain the pressure on the embossing plate 32 to achieve embossing forming. When the outer side walls of the arc segment 311 and the rounded corner segment 222 are respectively pressed against the upper and lower end surfaces of the cardboard, the connecting frame 12 stops moving, and the corresponding position of the cardboard is formed with embossing and bending. As the upper template 1 continues to move downward, it squeezes the first compression spring 41 to maintain the pressure on the connecting frame 12. The lower cutting edge of the die-cutting plate 10 abuts against the cardboard and forms a cut on the cardboard. When the inclined cutting surface 101 of the die-cutting plate 10 extends into the cavity structure formed by the enclosure of the outer side wall of the fixed block 22 and the wall of the groove 210, the die-cutting and blanking of the cardboard are completed.

[0030] Meanwhile, since the height difference between the upper end surface of the boss 221 and the plane where the higher end of the rounded corner segment 222 is located is 1 mm, a stepped edge with a 1 mm height difference is formed at the bending forming position of the cardboard. The formation of this stepped edge helps to maintain the consistency of the bending position during the subsequent processing and forming of the cardboard, and avoid bending deviation and affecting the processing quality.

[0031] Finally, after the upper template 1 moves down in place, it immediately moves back up to the standby position. The indentation plate 31 and the embossing plate 32 move back synchronously. The area of the cardboard to be processed is moved to the position of the fixed block 22, and then the upper template 1 is started to move down. This is repeated to complete the embossing and die-cutting forming process of the cardboard. At the same time, an indentation is formed on the cardboard, and a 1-mm stepped edge is formed between the indentation position and the embossing position.

[0032] For the processed cardboard, the side material of the cardboard is removed manually along the die-cutting edge, and the formed product is obtained.

[0033] It should be noted that in order to ensure the indentation purpose at the position of the indentation plate 31, the screwing connection position is set on the outer side surface of the connecting frame (as shown in the state in Figure 2 ), so as not to affect the integrity of the pattern at the indentation position.
