Specific Embodiments

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0030] As Figure 1As shown, an automatic die pressing mechanism and its paper box die cutting device, base 20, a motor is fixedly connected to the bottom of the base 20, and a frame 21 is fixedly connected to one side of the top of the base 20. The frame 21 is an inverted L-shaped bracket;

[0031] Hydraulic rod 22, the hydraulic rod 22 is fixedly connected to the lower wall surface at the top of the frame 21, and a mold 23 is fixedly connected to the bottom of the hydraulic rod 22. Both the motor and the hydraulic rod 22 are electrically connected to the power supply. Die patterns for die pressing are provided at the bottom of the mold 23. This is existing technology, so it will not be elaborated here.

[0032] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a conversion structure. The conversion structure can improve the efficiency during paper box die pressing. The conversion structure includes: a rotating plate 30, fixed rods 35, movable rods 37, and clamping columns 42. The rotating plate 30 is rotatably connected to the center of the top of the base 20. The fixed rods 35 are arranged on the top of the base 20. The movable rods 37 are symmetrically and slidably connected to the top of the base 20. The clamping columns 42 are also symmetrically and slidably connected to the top of the base 20.

[0033] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the rotating plate 30 is a capsule-shaped plate. The motor can drive the rotating plate 30 to rotate on the top of the base 20. The fixed rods 35 are symmetrically arranged on both sides of the top of the rotating plate 30. On each side, the fixed rod 35 and the movable rod 37 are parallel to each other. Both the fixed rod 35 and the movable rod 37 are rectangular rod-shaped. The clamping column 42 is semi-cylindrical. The clamping columns 42 are symmetrically arranged on both sides of the top of the rotating plate 30 respectively. The conversion structure further includes side grooves 31, wide grooves 32, long grooves 33, first cylinders 34, long blocks 36, and second cylinders 38. The side grooves 31 are symmetrically opened on the front and rear wall surfaces of the rotating plate 30 respectively. The wide grooves 32 are symmetrically opened on both sides of the top of the rotating plate 30 respectively. The long grooves 33 are symmetrically opened on the side wall surfaces of the rotating plate 30. The first cylinders 34 are respectively fixedly connected in the symmetric long grooves 33. The bottoms of the symmetric fixed rods 35 and the tops of the symmetric first cylinders 34 are fixedly connected. The long blocks 36 are slidably connected in the long grooves 33. The long blocks 36 in the long grooves 33 are also fixedly connected to the ends of the first cylinders 34. The tops of the symmetric long blocks 36 are also fixedly connected to the bottoms of the symmetric movable rods 37. The second cylinders 38 are respectively fixedly connected in each wide groove 32. The long grooves 33 can accommodate the sliding of the long blocks 36. The conversion structure further includes a third cylinder 40 and side blocks 41. The third cylinder 40 is slidably connected in the side groove 31. The side blocks 41 are fixedly connected to the side wall surface of the third cylinder 40. The tops of the side blocks 41 are also symmetrically and fixedly connected to the clamping columns 42 respectively. The third cylinder 40 is horizontally arranged at the end of the second cylinder 38. The third cylinder 40 and the side blocks 41 can slide in the side groove 31. The second cylinders 38 are symmetrically arranged on the front and rear wall surfaces of the cartridge case 43. The third cylinder 40 can be parallel to the first cylinder 34.

[0034] During specific use, place the required cardboard in the area between the symmetric clamping columns 42 on one side of the top of the rotating plate 30, and then control the power supply of the third cylinder 40, the first cylinder 34, and the second cylinder 38 to turn on. The first cylinder 34, the third cylinder 40, the second cylinder 38, and the third cylinder 40 can extend in length through power control. The first cylinder 34 can drive the long block 36 to move towards the cardboard wall surface in the long groove 33 when the power is turned on. The long block 36 can drive the movable rod 37 to contact the cardboard wall surface simultaneously. The second cylinder 38 can drive the third cylinder 40 to move towards the cardboard wall surface. When the third cylinder 40 moves, it will drive the side block 41 to move simultaneously. The side block 41 can drive the clamping column 42 to contact the cardboard wall surface. The third cylinder 40 can drive the side block 41 to move and align with the cardboard wall surface. After the four sides of the cardboard are fixed, at this time, the motor at the bottom of the base 20 can be driven to rotate the rotating plate 30 by 180 degrees on the top of the base 20. The rotating plate 30 can drive the cardboard on its top to move vertically towards the bottom of the mold 23 and stop when it reaches the bottom of the mold 23. At this time, control the power supply of the hydraulic rod 22 to drive the mold 23 to move towards the paper to perform die pressing on the cardboard. When the cardboard is being die pressed by the mold 23, the next cardboard to be die pressed can be placed at the other side position on the top of the rotating plate 30. Then, after the cardboard is die pressed, the motor continues to drive the rotating plate 30 to rotate so that the symmetric cardboard positions on the top of the rotating plate 30 are interchanged. At this time, the next cardboard can be die pressed, and then the die pressed cardboard can be removed from the top of the rotating plate 30 and replaced. In this way, placing the cardboard can be carried out reciprocally;

[0035] To sum up, by setting the conversion structure, the two cardboards can be rotated alternately through the rotating rotating plate 30, so that the removal of the cardboard and the die pressing of the cardboard can be carried out simultaneously, thus saving a large amount of time. And when placing and removing the cardboard, the distance between the worker and the mold 23 is relatively far. Therefore, compared with the prior art, the die pressing efficiency of this solution is higher and safer.

[0036] As Figure 1 and Figure 5 shown, a pressing structure is provided on the wall surface of the mold 23. The pressing structure includes a spring box 43, a top block 44, a spring plate 45, and a pressing block 46. The spring box 43 is symmetrically fixedly connected to the front wall surface of the mold 23. The spring box 43 is slidably connected between the symmetric spring boxes 43. The spring plate 45 is elastically connected between each pair of symmetric spring boxes 43 through a spring. The pressing block 46 is fixedly connected to the bottom of the spring plate 45. The spring box 43 is in the shape of a C-shaped plate. The openings of each pair of symmetric spring boxes 43 face each other. The top block 44 is in the shape of a T-shaped block. The spring plate 45 is elastically connected within the openings of the symmetric spring boxes 43. The pressing block 46 can be slidably connected between the symmetric spring boxes 43. Isosceles trapezoidal blocks are symmetrically fixedly connected to the bottom of the pressing block 46. The pressing structure is symmetrically arranged on the front and rear wall surfaces of the mold 23;

[0037] During specific use, when the mold 23 moves towards the top of the cardboard, it will drive the top block 44, the elastic plate 45, and the pressing block 46 to move simultaneously. The bottom of the pressing block 46 will stop when it contacts the top of the cardboard. At this time, since the mold 23 has not yet contacted the top of the cardboard, it will continue to move downward. After the mold 23 contacts the top of the cardboard, the elastic plate 45 on the top of the pressing block 46 will be squeezed by the spring in the opening of the spring box 43 due to the movement of the mold 23. At this time, the pressing block 46 will press the cardboard. When the mold 23 moves upward after the die pressing is completed, the pressing block 46 will fix the cardboard because the elastic plate 45 is resisted by the spring. After the mold 23 moves upward a certain distance and the bottom of the elastic plate 45 contacts the bottom inside the opening of the spring box 43, it can drive the pressing block 46 to move upward away from the top of the cardboard, thus canceling the pressing on the cardboard.

[0038] In summary, by setting the pressing structure, the top of the cardboard can be pressed downward before the mold 23 presses the cardboard, preventing the cardboard from warping on the top of the rotating plate 30 and affecting the die pressing quality. Therefore, the stability of the device during die pressing can be improved.

[0039] A carton die-cutting device, not shown in the figure, includes a die-cutting machine body and also includes all of the above automatic die pressing mechanisms.

[0040] In summary, by setting the automatic die pressing mechanism, the working efficiency of the device can be improved, and the safety of workers during work can also be ensured.

[0041] Working principle: Place the required cardboard in the area between the symmetric clamping columns 42 on one side of the top of the rotating plate 30, and then control the power supply of the third cylinder 40, the first cylinder 34, and the second cylinder 38 to be turned on. The first cylinder 34, the third cylinder 40, the second cylinder 38, and the third cylinder 40 can extend in length through power control. When the power supply of the first cylinder 34 is turned on, it can drive the long block 36 to move towards the cardboard wall surface in the long groove 33. The long block 36 can drive the movable rod 37 to contact the cardboard wall surface simultaneously. The second cylinder 38 can drive the third cylinder 40 to move towards the cardboard wall surface. When the third cylinder 40 moves, it will drive the side block 41 to move simultaneously. The side block 41 can drive the clamping column 42 to contact the cardboard wall surface. The third cylinder 40 can drive the side block 41 to move and align with the cardboard wall surface. After the four sides of the cardboard are fixed, at this time, the rotating plate 30 can be driven by the motor at the bottom of the base 20 to rotate 180 degrees on the top of the base 20. The rotating plate 30 can drive the cardboard on its top to move vertically towards the bottom of the mold 23 and stop when it reaches the bottom of the mold 23. At this time, control the power supply of the hydraulic rod 22 to be turned on to drive the mold 23 to move towards the paper to perform die pressing on the cardboard. When the cardboard is being die pressed by the mold 23, the next cardboard to be die pressed can be placed at the other side position on the top of the rotating plate 30. Then, after the cardboard is die pressed, the motor continues to drive the rotating plate 30 to rotate so that the symmetric cardboard positions on the top of the rotating plate 30 are interchanged. At this time, the next cardboard can be die pressed, and then the die pressed cardboard can be removed from the top of the rotating plate 30 and replaced. In this way, the cardboard can be placed repeatedly.
