They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] As shown in Figures 1 to 3, this embodiment provides a tool for disassembling and assembling a bottom cutting tool for cigarette packs. The bottom cutting tool for cigarette packs includes a cutting blade and a top blade. The cutting blade shaft is rotatably mounted on a cutting blade holder. A locking nut on the cutting blade holder locks the cutting blade holder onto the cutting device. The cutting blade is connected to the cutting blade shaft. A fixing nut on the cutting blade locks the cutting blade onto the cutting blade shaft. A protective cover is provided on the cutting blade holder. A fixing screw on the protective cover locks the protective cover onto the cutting blade holder. The top blade is located outside the protective cover and is used to hold the bottom cutting line of the cigarette pack to facilitate cutting. A fixing screw on the top blade locks the top blade onto the cutting blade holder.

[0029] The tool assembly and disassembly kit includes a column 1, a box nut wrench 2, and an Allen wrench 3. The first end of the column 1 has two spaced-apart locating pins 4, which can be inserted into the locating hole of the cutter shaft. The second end of the column 1 has an open-end nut wrench 5, used to tighten the cutter seat locking nut. The box nut wrench 2 includes a connected wrench head 6 and a wrench arm 7. The wrench head 6 is rotatably fitted onto the first end of the column 1 and has a first wrench hole 8 coaxial with the column 1, with the opening of the first wrench hole 8 facing the locating pin 4, used to tighten the cutter fixing nut. The Allen wrench 3 is connected to the second end of the column 1 at an angle, with a first Allen wrench head 9 at one end and a second Allen wrench head 10 at the other end. The first Allen wrench head 9 is used to tighten the protective cover fixing screw, and the second Allen wrench head 10 is used to tighten the top cutter fixing screw.

[0030] When disassembling the bottom cutting tool of the cigarette pack, first use the open-end nut wrench 5 to loosen the locking nut of the cutting tool holder; then use the first Allen wrench 3 to loosen the fixing screw of the protective cover, and use the second Allen wrench head 10 to loosen the fixing screw of the top blade, thus removing the top blade; then open the protective cover and insert the positioning pin 4 into the positioning hole of the cutting shaft to fix the cutting shaft and prevent it from rotating; next, use the first nut wrench hole 8 to engage the cutting tool fixing nut, and rotate the nut wrench head 6 through the nut wrench arm 7 to loosen the cutting tool fixing nut. At this time, hold the Allen wrench 3 to fix the column 1 still, and the cutting shaft will not rotate; after the cutting tool fixing nut is loosened, lift the column 1 upwards to separate the positioning pin 4 from the cutting shaft, separate the nut wrench head 6 from the cutting tool fixing nut, and remove the cutting tool fixing nut to disassemble the cutting tool, thus completing the disassembly of the bottom cutting tool of the cigarette pack. The operation steps for installing the bottom cutting tool are the reverse of the above, and will not be repeated here.

[0031] The aforementioned tool disassembly and assembly tool integrates various tools required for the bottom cutting tool of cigarette packs into one unit. It is suitable for disassembling and assembling the bottom cutting tool of Huanghelou Book-style 1916 cigarette packs. Using the tool disassembly and assembly tool provided in this embodiment can simplify the operation process, reduce the types of tools, and increase the disassembly and assembly speed, thereby shortening equipment downtime, improving production efficiency, and the compatible tools can help improve the tool installation accuracy, thereby reducing quality defects such as burrs and incomplete cutting at the bottom of the cigarette pack, and improving the product qualification rate.

[0032] Furthermore, the nut wrench head 6 is slidably connected to the column 1 along the axial direction of the column 1. The second end of the column 1 is circumferentially provided with a limiting boss 11, which is used to abut against the inner top wall of the nut wrench head 6 to limit the movement of the nut wrench head 6 along the axial direction of the column 1 towards the first end of the column 1, prevent the nut wrench head 6 from disengaging from the first end of the column 1, ensure smooth operation during use, and enhance the stability of the overall structure. The nut wrench head 6 is slidably connected to the column 1 along the axis of the column 1. The nut wrench head 6 is movable along the axis of the column 1. When it is necessary to insert the positioning pin 4 into the positioning hole, the nut wrench head 6 can be slid upward first to expose the positioning pin 4, so that the operator can accurately insert the positioning pin 4 into the positioning hole. Similarly, after disassembly, the nut wrench head 6 is slid upward first to separate from the cutter fixing nut, and then the column 1 is lifted to separate the positioning pin 4 from the positioning hole. The above settings can fix the cutter shaft on the one hand, and the column 1 is positioned by the positioning pin 4, which provides guidance and positioning for the movement of the nut wrench head 6, so that the first nut wrench hole 8 can be accurately and smoothly engaged or disengaged from the cutter fixing nut, improving the accuracy and efficiency of the operation. Moreover, moving the nut wrench head 6 makes it easier for the operator to observe the positioning pin 4 and avoid the positioning pin 4 from colliding with or even breaking the cutter shaft.

[0033] As shown in Figures 1 and 3, the tool disassembly and assembly tool also includes a limiting member 12. The limiting member 12 is spaced apart from the limiting boss 11 along the axial direction of the column 1, and the limiting member 12 protrudes from the circumference of the column 1. The limiting member 12 is used to abut against the outer top wall of the nut wrench head 6 to limit the movement stroke of the nut wrench head 6 along the axial direction of the column 1 towards the second end of the column 1, thereby limiting the lifting stroke of the nut wrench head 6, ensuring the structural stability of the tool disassembly and assembly tool, preventing the nut wrench head 6 from falling off the second end of the column 1 or colliding with the internal hex wrench 3, and increasing operational safety.

[0034] Furthermore, the limiting member 12 is detachably connected to the column 1, which facilitates the assembly and disassembly of the column 1 and the box nut wrench 2, thereby facilitating maintenance and replacement.

[0035] In this embodiment, the limiting member 12 is a retaining spring, and the column 1 has a retaining groove in the circumference. The retaining spring can be engaged in the retaining groove. Its structure is simple, the connection is stable, the disassembly and assembly are convenient, and it is easy to adjust and replace.

[0036] In other embodiments, the limiting member 12 may include, but is not limited to, a pin inserted into the column 1, or a nut threadedly connected to the column 1, which is not limited here.

[0037] As shown in Figure 1, the second end of the column 1 has a through mounting hole perpendicular to the axis of the column 1. The hex wrench 3 can be slidably inserted into the mounting hole, thereby realizing the assembly of the hex wrench 3 and the column 1. According to the usage requirements and the working habits of the staff, the relative position of the hex wrench 3 and the column 1 can be freely adjusted, thereby flexibly adjusting the torque, adapting to different working postures, and improving the convenience of operation.

[0038] Furthermore, the tool disassembly and assembly tool also includes a locking component 13, which is threadedly connected to the column 1 and can pass through the side wall of the mounting hole and abut against the internal hex wrench 3. After the internal hex wrench 3 is adjusted to a suitable position, the position of the internal hex wrench 3 is fixed by the locking component 13, which can maintain stable torque, prevent the tool from loosening during use, save adjustment time, and improve disassembly and assembly efficiency.

[0039] It should be noted that the positioning hole of the cutter shaft is a round hole, and the lower end of the positioning hole is closed. In order to ensure positioning accuracy, the positioning pin 4 and the positioning hole need to be precisely fitted. However, excessive precision fitting results in excessive airtightness of the positioning hole, which can easily lead to difficulty in inserting the positioning pin 4. To solve the above problem, as shown in Figure 1, in this embodiment, the positioning pin 4 is semi-cylindrical. The circumferential surface of the semi-cylindrical positioning pin 4 can fit with the side wall of the positioning hole. Under the premise of ensuring the positioning accuracy and positioning strength of the positioning pin 4 and the positioning hole, there is a gap between the straight surface of the positioning pin 4 and the positioning hole to facilitate the insertion of the positioning pin 4 into the positioning hole.

[0040] In this embodiment, a hanging hole is provided at the end of the nut wrench arm 7 away from the nut wrench head 6. The hanging hole is used to hang the tool disassembly and assembly tools, so as to store the tool disassembly and assembly tools, keep the production site clean, and make them easy to access.

[0041] Furthermore, the hanging hole is a second nut wrench hole 14, and the model of the second nut wrench hole 14 is smaller than that of the first nut wrench hole 8, which is used to tighten other nuts of the cutting equipment, further improving the space utilization and practicality of the tool disassembly and assembly.

[0042] In this embodiment, regarding the bottom cutting device for the Huanghelou Book-style 1916 cigarette pack, the cutter seat locking nut is model M10, the cutter fixing nut is model M20, the protective cover fixing screw is model M6 hexagon socket screw, and the top cutter fixing screw is model M8 hexagon socket screw. Therefore, the opening size of the open nut wrench 5 is 16mm, the side dimension of the first nut wrench hole 8 is 30mm, the side dimension of the first hexagon socket wrench head 9 is 5mm, and the side dimension of the second hexagon socket wrench head 10 is 6mm, which is suitable for the disassembly and assembly of the bottom cutting tool for the Huanghelou Book-style 1916 cigarette pack. In addition, the side dimension of the second nut wrench hole 14 is 13mm, which is a commonly used size on the bottom cutting device for the Huanghelou Book-style 1916 cigarette pack.

[0043] Of course, the wrench model mentioned above can be adjusted to accommodate different types of nuts and screws, and no limitation is made here.

[0044] Optionally, the width of the nut wrench arm 7 gradually decreases in the direction away from the nut wrench head 6 to improve the operator's grip comfort and optimize the operating experience.

[0045] 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
