[0035] This embodiment provides a steel printing roller structure that is easy to assemble and disassemble, quick and convenient to change printed text, and has high work efficiency.

[0036] Specifically, such as Figure 1As shown, the stamping roller structure includes a roller base 100, multiple stamping modules 200, a fixing member 300, and a positioning member 400. Exemplarily, the number of stamping modules 200 can be two, three, or four. The roller base 100 is fixed to a rotating shaft (not shown in the figure), and the rotation of the rotating shaft can drive the roller base 100 to roll. Multiple mounting grooves 110 are recessed on the surface of the roller base 100, and the multiple mounting grooves 110 are spaced apart circumferentially along the surface of the roller base 100. Each stamping module 200 corresponds one-to-one with a mounting groove 110, and the shape of the stamping module 200 is adapted to the shape of the mounting groove 110. The roller base 100 and all the stamping modules 200 are assembled to form a cylindrical roller, and the surface of the stamping module 200 is provided with printed characters 210. The fixing component 300 detachably installs the stamping module 200 onto the roller base 100; each stamping module 200 is provided with a first positioning hole 220, and the bottom wall of the corresponding mounting groove 110 is provided with a second positioning hole 111. The second positioning hole 111 corresponds one-to-one with the first positioning hole 220. The positioning component 400 passes through the first positioning hole 220 and the second positioning hole 111 to position and install the stamping module 200. The position of the first positioning hole 220 is different on different stamping modules 200.

[0037] Based on the above design, the roller base 100 is fixed on the rotating shaft, and the rotation of the rotating shaft can drive the roller base 100 to roll. Multiple mounting grooves 110 are recessed on the surface of the roller base 100, spaced circumferentially along the surface of the roller base 100, all for mounting the stamping module 200. The roller base 100 and the stamping module 200 are assembled to form a cylindrical roller. The surface of the stamping module 200 is printed with characters 210, achieving roll printing. The fixing component 300 detachably mounts the stamping module 200 to the roller base 100, making the disassembly and assembly of the stamping module 200 convenient. Simultaneously, the roller base 100 and the stamping module 200 are manufactured separately, allowing for quick replacement of the printed characters 210 by simply replacing the stamping module 200. This improves work efficiency and avoids repeatedly disassembling the entire stamping roller structure from the rotating shaft, protecting the entire equipment. Each stamped module 200 is provided with a first positioning hole 220, and the bottom wall of the corresponding mounting slot 110 is provided with a second positioning hole 111. The positioning component 400 passes through the first positioning hole 220 and the second positioning hole 111, which can position and install the stamped module 200, thereby improving the installation accuracy of the stamped module 200. The positions of the first positioning holes 220 on different stamped modules 200 are different. By matching the stamped module 200 with the unique corresponding mounting slot 110 through the first positioning hole 220 and the second positioning hole 111, the work efficiency is improved.

[0038] In this embodiment, the first positioning hole 220 and the second positioning hole 111 are both threaded through holes, and the positioning component 400 is an M4 positioning screw.

[0039] Optionally, the roller base 100 is provided with a through hole 120 extending along a first direction, which is the axial direction of the rotating shaft. A groove 130 is provided on the inner wall of the through hole 120. The rotating shaft passes through the through hole 120 and is at least partially engaged in the groove 130, thus fixing the roller base 100 to the rotating shaft and allowing it to rotate with the rotating shaft. This method is simple to install and has high connection strength.

[0040] In this embodiment, the slot 130 extends through the first direction.

[0041] Optionally, the stamping module 200 is provided with a first through hole 230, and the bottom wall of the mounting groove 110 is provided with a second through hole 112. The fixing member 300 passes through the first through hole 230 and the second through hole 112 in sequence to connect the stamping module 200 and the roller base 100. The connection between the stamping module 200 and the roller base 100 is realized through the fixing member 300, the first through hole 230 and the second through hole 112, which is simple to manufacture and has high connection strength.

[0042] Furthermore, the surface of the stamping module 200 is recessed with a countersunk groove, which is arranged circumferentially along the first through hole 230. The end of the fixing member 300 is engaged in the countersunk groove to prevent the end of the fixing member 300 from extending beyond the outer surface of the cylindrical roller and affecting the printing of the printed characters 210.

[0043] In this embodiment, the fastener 300 is an M5 fastening screw, and the countersunk groove is an M5 internal hexagon countersunk groove; and each stamped module 200 corresponds to two M5 fastening screws, that is, the number of the first through hole 230, the second through hole 112 and the countersunk groove are all two.

[0044] Optionally, the mounting groove 110 extends along a first direction, which is the axial direction of the rotating shaft. This simplifies the structure of the mounting groove 110 and the stamping module 200, making them easier to manufacture. Simultaneously, it maximizes the size of the stamping module 200 in the first direction, allowing for multiple printed characters 210 on the module. For example, the printed characters 210 can be two, three, or five. The multiple printed characters 210 are evenly spaced along the first direction, enabling the stamping roller structure to print on multiple sets of cigarette paper simultaneously.

[0045] In this embodiment, the printed characters 210 are printed in two layers.

[0046] To reduce the manufacturing difficulty of the stamping module 200 and the mounting groove 110, the side of the stamping module 200 facing the rotating shaft is an arc surface, and the bottom wall of the mounting groove 110 is also an arc surface, with the arc surface coaxial with the cylindrical roller.

[0047] In this embodiment, according to actual needs, there are two mounting slots 110, and the two mounting slots 110 are arranged opposite each other along the radial direction of the cylindrical roller, which facilitates the separation of cigarette paper.

[0048] Furthermore, the included angle α between the two inner sidewalls of the mounting groove 110 is 90 degrees, meaning that the outer area of ​​the stamp module 200 is one-quarter of the side surface area of ​​the cylindrical roller.

[0049] It should be noted that this steel stamping roller structure is mainly suitable for the M5 cigarette machine, but it can also be used in the same model units such as M5E and M5S, making it highly adaptable.

[0050] This embodiment also provides a cigarette rolling machine with high working efficiency.

[0051] Specifically, the device includes a machine body and the aforementioned stamping roller structure. A roller base 100 is fixed to the rotating shaft of the machine body, which drives the roller base 100 to rotate, thereby rotating the stamping roller structure. The roller base 100 has multiple recessed mounting grooves 110 spaced circumferentially along its surface. Each stamping module 200 corresponds to one of the mounting grooves 110, and the shape of the stamping module 200 matches the shape of the mounting groove 110. Printed characters 210 are printed on the surface of the stamping module 200, enabling roll printing. A fixing member 300 detachably mounts the stamping module 200 to the roller base 100. This detachable connection facilitates the assembly and disassembly of the stamping module 200. Furthermore, the roller base 100 and the stamping module 200 are manufactured separately, allowing for quick replacement of the printed characters 210 by simply replacing the stamping module 200. This improves work efficiency and avoids repeatedly disassembling the entire stamping roller structure from the rotating shaft, protecting the entire cigarette machine. Each stamped module 200 has a first positioning hole 220, and the bottom wall of the corresponding mounting slot 110 has a second positioning hole 111. The positioning component 400 passes through the first positioning hole 220 and the second positioning hole 111 to position and install the stamped module 200, thereby improving the installation accuracy of the stamped module 200. The positions of the first positioning holes 220 on different stamped modules 200 are different. By using the first positioning holes 220 and the second positioning holes 111, the stamped module 200 is paired and installed with the unique corresponding mounting slot 110, improving work efficiency.

[0052] It should be noted that the principle of the rotating shaft of the cigarette machine driving the steel printing roller structure to rotate and roll for printing is existing technology and will not be described in detail here.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
