[0002] The packaging box embossing machine is a mechanical device used to apply embossed patterns on various packaging boxes. The embossing machine generates pressure through a hydraulic system or mechanical structure to press the concave and convex patterns on the embossing roller or embossing mold onto the surface of the material.

[0003] After searching, the publication (announcement) number CN215704482U provides a multi-roller structure of a liquor packaging box embossing machine; including a machine table, a notch is provided at the center of the outer wall of the top of the machine table, and a transmission groove is provided at the top of the inner wall adjacent to the notch, a transmission block is slidably connected inside the transmission groove, and a screw is threadedly connected at the axis of the outer wall of the top of the machine table, a handwheel is welded to the top of the screw, and one end of the screw located inside the transmission groove is movably connected to the axis of the outer wall of the top of the transmission block through a bearing. The handwheel of the utility model drives the screw to rotate, and the screw drives the transmission block to rise and fall along the transmission groove, and the transmission block drives the conveying roller to rise and fall through the transmission shaft, so that the conveying roller can be adjusted in time and effectively according to different embossing requirements. The column rod plays a good buffering role on the limit seat under the action of the limit plate and the vortex spring, so that the fit between the embossing roller and the conveying roller is more compact, thereby improving the embossing effect of the packaging box.

[0004] However, in the current embossing machine, the embossing roller needs to be completely disassembled to replace the embossing pattern, and the embossing roller with the corresponding pattern needs to be replaced. The overall disassembly and assembly are complicated, and the replacement of the embossing roller is slow, which delays the efficiency of embossing the packaging box.

[0005] For this reason, we propose a multi-roller structure of a packaging box embossing machine to solve the existing problems. Utility Model Content

Through the cooperation of the above-mentioned structure, the spacing between the engraving cylinder and the conveying roller can be quickly changed, and the engraving cylinder can be quickly replaced.

[0008] Preferably, the outer wall of the shaft is provided with grooves at equal intervals, and the inner wall of the grooved cylinder is provided with protrusions at equal intervals, and the protrusions are movably inserted into the grooves, thereby ensuring that the grooved cylinder does not deflect on the shaft.

[0011] Preferably, the gear ring is provided at the bottom end of the screw, and the gear ring is in a gear meshing state with the gear. Through the cooperation of the above structure, the rotation of the screw controls the lifting and lowering of the slide bed.

[0012] Preferably, the lifting assembly is composed of a vertical rod and a vertical cylinder. The vertical rod is arranged at the bottom end of the side block, and the lower end of the vertical rod is slidably inserted into the side seat. The vertical rod defines the moving trajectory of the side block.

[0013] Preferably, the vertical cylinder is arranged on the outer wall of the side seat, and the output end of the vertical cylinder is arranged on the side block, which can control the side block to rise and fall.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] During the use of the multi-roller structure of the packaging box embossing machine of the utility model, each engraving cylinder and the conveying roller rotate at a constant speed, and the cardboard for the packaging box to be processed is fed between the engraving cylinder and the conveying roller. The multiple embossing rollers apply pressure to the material in turn, so that the desired pattern is formed on the surface of the cardboard;

[0018] During this process, the distance between the engraving cylinder and the conveying roller can be adjusted by the screw assembly to meet the embossing requirements of cardboards of different thicknesses;

[0020] Then the side block moves upward and the side seat is reset, so that the rotary head can be inserted into the square groove of the shaft, and the rotary head rests on one end of the engraving cylinder to fix the position of the engraving cylinder;

[0021] The above steps allow the embossing pattern to be replaced without disassembling the entire embossing roller. The replacement time of the compressed embossing can significantly reduce production downtime, improve overall production efficiency, reduce the time and labor required for mold change, and thus reduce labor costs.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1-Figure 5 As shown, the multi-roller structure of the packaging box embossing machine proposed in the utility model includes a slide bed 1, a machine table 3, a side block 7 and a side seat 9. The machine table 3 is provided with a side plate 4. The slide bed 1 is in sliding contact with the side plate 4, and a conveying roller 5 is equidistantly rotated on the slide bed 1. The slide bed 1 is lifted and lowered on the machine table 3 by a screw assembly. The upper end of the side plate 4 is equidistantly rotated with a shaft 11, and an engraving cylinder 6 is sleeved on the shaft 11. A rotary head 18 is equidistantly rotated on the side block 7, and the rotary head 18 is inserted at the end of the shaft 11. The side block 7 is provided on the side seat 9 through a lifting assembly, and the side seat 9 is provided on the side of the machine table 3 through a translation assembly.

[0032] Based on Example 1:

[0033] During the use of the multi-roller structure of the packaging box embossing machine of the utility model, each engraving cylinder 6 and the conveying roller 5 rotate at a constant speed, and the packaging box cardboard to be processed is fed between the engraving cylinder 6 and the conveying roller 5. Under the action of the rotating feeding, the cardboard passes at a constant speed, so that the desired pattern is formed on the surface of the cardboard;

[0034] During this process, the distance between the engraving cylinder 6 and the conveying roller 5 can be adjusted by the screw assembly to meet the embossing requirements of cardboards of different thicknesses;

[0035] Furthermore, when the embossing pattern needs to be changed, after the embossing machine is stopped, the side seat 9 is controlled by the translation assembly to move away from the machine table 3, and the side seat 9 drives the side block 7 to move so that the rotary head 18 is separated from the shaft 11. Then, the side block 7 is controlled to move downward by the lifting assembly, so that the rotary head 18 moves downward to directly expose the end of the engraving cylinder 6. At this time, the operator can apply force outward to pull the engraving cylinder 6 off the shaft 11, and then replace the engraving cylinder 6 with a different pattern.

[0036] Then the side block 7 moves upward and the side seat 9 is reset, so that the rotary head 18 can be inserted into the square groove 12 of the shaft 11, and the rotary head 18 abuts against one end of the engraving cylinder 6 to fix the position of the engraving cylinder 6.

Through the cooperation of the protrusions and the grooves, relative rotation between the engraving cylinder 6 and the conveying roller 5 can be avoided. A square groove 12 is provided at the end of the shaft 11, and the square part of the rotary head 18 is inserted in the square groove 12. The diameter of the rotary head 18 is larger than the diameter of the shaft 11. The rotation of the shaft 11 through the square groove 12 can drive the rotary head 18 to rotate synchronously, so that the rotary head 18 is blocked at the end of the shaft 11 on the one hand, and provides support for the shaft 11 on the other hand, thereby facilitating the disassembly and assembly of the engraving cylinder 6.

[0039] The screw assembly consists of a gear 13, a ring gear 14 and a screw 15. The gear 13 is rotatably arranged inside the machine table 3, and the screw 15 is rotatably arranged on the machine table 3.

The ring gear 14 and the gear 13 are in a gear meshing state. The power device drives the gear 13 to rotate, and the screw 15 is rotated through the meshing action between the gear 13 and the ring gear 14. Under the principle of the screw, the rotation action of the screw 15 can be converted into the lifting action of the slide bed 1.

The output end of the horizontal cylinder 16 is arranged on the side seat 9. One end of the horizontal rod 17 is arranged on the side seat 9. The other end of the horizontal rod 17 is movably inserted in the machine table 3. The horizontal rod 17 limits the moving trajectory of the side seat 9, and the horizontal cylinder 16 controls the side seat 9 to perform translational movement.

[0043] The lower surface of the machine platform 3 is provided with support bases 2 . There are four support bases 2 in total, and the positions of the four support bases 2 are distributed in a rectangular array on the lower surface of the machine platform 3 .

The cardboard passes between the engraving cylinder 6 and the conveying roller 5 at a constant speed, and the multiple engraving cylinders 6 apply pressure to the material in turn, so that the desired pattern is formed on the surface of the cardboard;

[0046] During this process, the distance between the engraving cylinder 6 and the conveying roller 5 can be adjusted by the screw assembly, so that cardboards of different thicknesses can be embossed;
