It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] Please refer to Figures 1-6, the present utility model provides a cardboard indentation device for color printing packaging, including a box body 1 with a through hole in the front and back of the middle, which facilitates the movement of the cardboard from the inside for indentation work. A control panel 2 is installed on the outside of the box body 1, enabling the staff to easily operate the electrical components inside the device, making the operation more convenient. A number of rotating rollers 3 are connected in parallel inside the box body 1 through bearings to facilitate the movement and indentation of the cardboard. A motor 4 is installed on the outside of the box body 1, and the output end of the motor 4 is connected to one of the rotating rollers 3. By driving the rotation of the rotating roller 3 by the motor 4, it is convenient to drive the cardboard to move under force. And the rotating roller 3 connected to the motor 4 is vertically corresponding to the annular scoring knife 111, so that the indentation work is carried out during the movement. An elevating frame 11 is installed at the upper end inside the box body 1, and a first electric push rod 5 is installed at the top of the box body 1. The output end of the first electric push rod 5 penetrates the box body 1 and is connected to the elevating frame 11. Thus, by pushing the elevating frame 11 with the first electric push rod 5, the height of the lower pressing roller 14 is adjusted to achieve work such as pressing different thickness cardboard. Both sides of the lower end of the elevating frame 11 are provided with side connecting plates 13, and a slot 15 is provided in the middle of the side connecting plates 13. The side connecting plates 13 are connected with the lower pressing rollers 14 through bearings on both sides of the slot 15, dividing the side connecting plates 13 into two sides, so that the lower pressing rollers 14 are installed on both sides, enabling both sides to be stressed to press the cardboard during indentation to avoid the situation of the cardboard warping. A push plate 16 is connected inside the slot 15, and the push plate 16 fits with the slot 15 to increase the stability effect. A third electric push rod 12 is installed inside the elevating frame 11, and the output end of the third electric push rod 12 penetrates the elevating frame 11 and is connected to the push plate 16. Both sides of the lower end of the push plate 16 are connected with mounting plates 17, and a fixing rod 18 is connected between the mounting plates 17. A number of annular scoring knives 111 are slidably connected between the fixing rods 18. Thus, when the third electric push rod 12 pushes the push plate 16, the height of the annular scoring knives 111 at the lower end is adjusted to enable indentation work with different depths.

[0031] Preferably, a fixed sleeve 19 is connected inside the annular scoring knife 111 through a connecting bearing 110 and is slidably connected with the fixed rod 18. Under the action of the connecting bearing 110, the annular scoring knife 111 can rotate for indentation work. A number of threaded holes 112 are provided at the upper end of the fixed rod 18, and a fixing hole 113 is provided at the upper end of the fixed sleeve 19. A fixing bolt 114 is provided inside the fixing hole 113 and is connected with the threaded hole 112. Thus, by fixing the fixed sleeve 19 with the fixing bolt 114, the annular scoring knife 111 can be fixed to prevent it from moving left and right, so as to adjust the distance between the annular scoring knives 111 to perform indentation work at different positions, avoiding difficult adjustment, saving working time, and making the working efficiency higher. And both the fixed sleeve 19 and the fixed rod 18 are rectangularly arranged, making the force better and more stable.

[0032] Preferably, limiting plates 8 are provided on both sides inside the box body 1 to limit both sides of the cardboard. A number of through holes 9 are provided inside the limiting plates 8 and are slidably connected to the rotating rollers 3 to prevent the rotating rollers 3 from interfering with and blocking the limiting plates 8 during the movement process. A second electric push rod 6 is installed outside the box body 1, and the output end of the second electric push rod 6 penetrates the box body 1 and is connected to the limiting plate 8, so that the second electric push rod 6 pushes the limiting plate 8 to move it. An expansion rod 7 is provided outside the box body 1, and the expansion rod 7 penetrates the box body 1 and is connected to the limiting plate 8 to make the limiting plate 8 more stable. The expansion rod 7 and the second electric push rod 6 are symmetrically arranged left and right, so that the force-bearing effect of the limiting plate 8 is better and the situation of uneven upward and downward force movement is avoided. An activity groove 10 is provided inside the limiting plate 8, and the activity groove 10 is opened at the upper end of the through hole 9 and is slidably connected to the lifting frame 11, so that after the limiting plate 8 moves inward, the situation that the lifting frame 11 interferes with it during the downward process is avoided. And the activity groove 10 includes three through holes 9, which correspond to the lower pressing rollers 14 and the annular scoring knives 111, making the cardboard more stable and the scoring effect better.

[0033] Working principle: When in use, first connect the control panel 2, the motor 4, the first electric push rod 5, the second electric push rod 6 and the third electric push rod 12 to an external power source. Then when the cardboard is placed on the rotating roller 3, start the second electric push rod 6 to push the limiting plate 8 to move inward, so that after the limiting plate 8 is adjusted to a suitable position according to the cardboard, the cardboard is limited to prevent left and right movement. Then the first electric push rod 5 pushes the lifting frame 11 downward so that the lower pressing rollers 14 are in contact with and press the cardboard evenly. Then during the process that the third electric push rod 12 pushes the pushing plate 16 downward, the lower annular scoring knives 111 are in contact with the cardboard to perform the scoring work, and the cardboard moves to perform the scoring under the drive of the motor 4 to drive the rotating roller 3 to rotate, thereby completing the work.
