[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a partial embossing device for producing digitally printed packaging boxes, including a base 1, a support block 2, and an assembly frame 3. The support block 2 is provided on the top of the base 1, and the assembly frame 3 is fixedly connected to the back side of the base 1. A lifting cylinder 13 is fixedly installed on the top of the assembly frame 3. An embossing plate 4 is fixedly installed on the output end of the lifting cylinder 13 through a connecting mechanism. A fixing mechanism is provided on the top of the base 1 to fit the packaging box onto the support block 2. The packaging box and the support block 2 are fixed together by the fixing mechanism. The embossing plate 4 is then installed on the output end of the lifting cylinder 13 through the connecting mechanism. The output end of the lifting cylinder 13 can drive the embossing plate 4 to move downward, and the embossing plate 4 embosses the packaging box on the top of the support block 2. Then, the output end of the lifting cylinder 13 drives the embossing plate 4 to move upward and reset, and the embossed packaging box is removed from the outside of the support block 2.

[0021] The fixing mechanism includes a lead screw 6, a slider 7, a clamping rod 8, and a connecting rod 10. The top of the base 1 is provided with a sliding groove 5. The lead screw 6 is rotatably connected inside the sliding groove 5, and the slider 7 is slidably connected inside the sliding groove 5. A set of clamping rods 8 are fixedly connected to both the slider 7 and the base 1. The bottom of one side of the base 1 is hinged to the bottom of the slider 7 through the connecting rod 10. One end of the lead screw 6 passes through the interior of the slider 7 and is threadedly connected to it.

[0022] One end of the lead screw 6 passes through the interior of the base 1 and is fixedly connected to a handwheel 9. The positions of the two sets of clamping rods 8 are symmetrical to each other. The connecting rod 10 is composed of two rotating rods, and one end of the two rotating rods is hinged to each other.

[0023] After the packaging box is fitted onto the outside of the support block 2, the lead screw 6 and the slider 7 are threaded together, and the movement trajectory of the slider 7 is limited by the connecting rod 10 and the lead screw 6. By turning the handwheel 9, the lead screw 6 is driven to rotate in the forward direction inside the slide groove 5, which drives the slider 7 to move to the left side of the base 1, so that the two sets of clamping rods 8 cooperate to clamp the packaging box and prevent the packaging box from shifting during the embossing process. By turning the handwheel 9, the lead screw 6 is driven to rotate in the reverse direction inside the slide groove 5, which drives the clamping rods 8 on the slider 7 to separate from the packaging box. At this time, the embossed packaging box can be removed from the support block 2.

[0024] A top plate 11 is fixedly connected to the top of the base 1. A connecting rod 12 is symmetrically fixedly connected to one side of the top plate 11. The top end of the connecting rod 12 is fixedly connected to one side of the support block 2 by bolts. After one side of the support block 2 is placed against one side of the connecting rod 12, the support block 2 and the connecting rod 12 are fixed together by bolts. The support block 2 and the top plate 11 do not contact each other, which makes it convenient to put the packaging box on the support block 2.

[0025] The embossed plate 4 and the support block 2 are parallel vertically. The support block 2 is located in the middle of the two sets of clamping rods 8. The support block 2 and the top plate 11 have the same shape and the same length and width.

[0026] The connecting mechanism includes a threaded rod 14, a threaded sleeve 15, a plug rod 16, and a nut 17. The output end of the lifting cylinder 13 is fixedly connected to the threaded rod 14, the bottom end of the threaded rod 14 is fixedly connected to the plug rod 16, the top of the embossed plate 4 is fixedly connected to the threaded sleeve 15, and the outer side of the threaded rod 14 is threadedly connected to the nut 17.

[0027] The bottom end of the insert rod 16 is inserted into the inside of the threaded sleeve 15. The diameter of the threaded rod 14 is equal to that of the threaded sleeve 15. The inner wall of the nut 17 is threadedly connected to the outer wall of the threaded sleeve 15.

[0028] Place the threaded sleeve 15 at the bottom end of the threaded rod 14, then lift the embossing plate 4 upwards so that the insertion rod 16 at the bottom end of the threaded sleeve 15 is inserted into the inside of the threaded sleeve 15. At this time, the bottom end of the threaded rod 14 is aligned with the top end of the threaded sleeve 15. Tighten the nut 17 at the bottom end of the threaded rod 14 to the connection point between the threaded rod 14 and the threaded sleeve 15 to connect the threaded rod 14 and the threaded sleeve 15 into one unit. The embossing plate 4 can be installed at the output end of the lifting cylinder 13. The output end of the lifting cylinder 13 can drive the embossing plate 4 to move downwards, and the embossing plate 4 automatically embosses the packaging box.

[0029] The partial embossing device for this digitally printed packaging box involves attaching the packaging box to the outside of the support block 2. The lead screw 6 and the slider 7 are threaded together, and the movement trajectory of the slider 7 is limited by the connecting rod 10 and the lead screw 6. By turning the handwheel 9, the lead screw 6 is driven to rotate in the forward direction inside the slide groove 5, which drives the slider 7 to move to the left side of the base 1. This allows the two sets of clamping rods 8 to work together to clamp the packaging box, preventing the packaging box from shifting during the embossing process. This solves the problem in the prior art where digitally printed packaging boxes are not fixed and are prone to displacement during operation, resulting in changes in the embossing position and inconvenience in use.
