[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] Example 1

[0040] like Figure 1 、 Figure 2 As shown, the utility model proposes a novel split end scanning drum of a crimping machine unit, comprising a circular ring cam 1, a cylindrical main body 2 and a cover plate 3;

[0041] An annular cam 1 is sleeved on the outer circumferential wall of both ends of the cylindrical body 2; the annular cam 1 and the cylindrical body 2 are an integrally formed structure;

[0042] A cleaning hole 4 is provided in the middle of the cylindrical main body 2 , and the cleaning hole is located between the two annular cams 1 . A detachable cover plate 3 is provided in the cleaning hole 4 .

[0043] The split-end scanning drum provided by this utility model is connected to the original main shaft of the winding unit via bolts, which is the same as the original wheel connection method of the equipment and will not be repeated here. By opening a cleaning hole in the cylindrical body of the drum, the drum can be cleaned and maintained online without completely disassembling the drum. The adjustment process no longer requires a large number of tools, auxiliary components to be disassembled, and human resources, but only one person can complete the cleaning and maintenance with a set of tools and no auxiliary components to be disassembled. Moreover, the use of this split-end scanning drum not only meets the performance requirements of the equipment, but also greatly reduces the maintenance time of the equipment and improves the effective operation rate of the equipment.

[0044] As a further technical solution, Figure 3 、 Figure 4 、 Figure 5 As shown, the annular cam 1 includes a cam body 101 and a cam cover 102 detachably connected to the cam body 101 . A groove 103 for engaging the boss 302 on the cover plate is formed on a side of the cam cover 102 that contacts the cam body 101 .

[0045] The cam body 101 and the cam cover 102 are split structures obtained by cutting along a chord that does not pass through the center of the annular cam. The plane after cutting is a rectangular plane, which is located above the outer circumferential wall of the cylindrical body 2.

[0046] The cam body 101 and the cam cover 102 are connected by screws 5; the cylindrical body 2 is fixed to the drive shaft of the machine by four M6 bolts using the original screw holes of the equipment; the O-ring is installed in the sealing groove of the cover plate 3. After the cover plate 3 is covered in the cleaning hole 4 on the cylindrical body 2, the bosses 302 at both ends of the cover plate 3 are clamped in the grooves 103 on the cam cover 102, thereby indirectly fixing the cover plate 3.

[0047] Through the cooperation of the above-mentioned structure, this embodiment converts the axial overall disassembly of the traditional drum wheel into radial partial disassembly, so that the maintenance operation can be completed by simply removing the cam cover and the cover plate, which greatly improves work efficiency and changes the current situation of the cumbersome maintenance process of the end scanning drum wheel lag failure.

[0048] In this embodiment, the groove 103 is used to cooperate with the boss 302 of the cover plate. The dimensions of the groove 103 are 50 mm in length, 5 mm in width, 4 mm in height, and 3.5 mm in bottom chamfer. The dimensions of the groove 103 can be selected as needed and are not limited to the dimensions listed in this embodiment.

[0049] As a further technical solution, a cigarette receiving groove 104 is provided on the annular cam 1. The cigarette receiving groove 104 is arranged parallel to the central axis of the annular cam 1. The cigarette receiving groove 104 is used to accommodate cigarettes. It is an existing structure on the drum wheel and will not be described in detail here.

[0050] As a further technical solution, Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As well as Figure 10 As shown in (a) and (b), the cover plate 3 includes a cover plate body 301, and the cover plate body 301 is symmetrically provided with bosses 302 at both ends facing the annular cam 1;

[0051] The shape of the cover body 301 matches the shape of the cleaning hole 4 , for example, both are rectangular structures, and the cover body 301 is installed in the cleaning hole 4 .

[0052] The boss 302 is protruding from the cover body 301 , and one end of the boss 302 is connected to the cover body 301 through an inclined plate, and the other end is clamped in the groove 103 on the annular cam 1 to be fixed.

[0053] A quick-release slot 303 is formed at one end of the boss 302 facing the annular cam 1 , so that the cover plate 3 can be easily disassembled.

[0054] The cover plate 3 covers the cleaning hole 4 on the cylindrical main body 2, and the bosses 302 at both ends are located on the cam body 101. Then, the cam cover 102 and the cam body 101 are connected to realize the assembly of the drum.

[0055] In this embodiment, the bottom edge of the cover body 301 is 156mm long and 34mm wide. The boss dimensions are 50mm long, 5mm wide, 4mm high, and a 3.5mm top chamfer. A quick-release slot 303 is reserved below the boss 302 for quick removal of the cover. The dimensions of the quick-release slot 303 are 30mm long, 2mm deep, 1.5mm high, and a 1mm top chamfer. The dimensions of the various components described above in this embodiment can be adjusted as needed and are not limited to the dimensions shown in this embodiment.

[0056] As a further technical solution, the cleaning hole 4 is a symmetrically arranged rectangular hole, and the matching surface between the cover plate 3 and the cleaning hole on the cylindrical body 2 adopts a stepped inclined surface structure.

[0057] Specifically, the circumference of the cover plate body 301 and the cleaning hole 4 is a stepped structure, with the lower and upper vertical surfaces of the stepped structure being inclined. In the stepped structure, the upper long side has a 45° bevel, while the middle portion forms a horizontal transition surface connecting the upper and lower bevels. The upper and lower bevels have the same inclination direction, while the lower short side has a 7° bevel. The utility model utilizes a stepped bevel structure, which achieves a better seal on the cylindrical body than a vertical mating surface.

[0058] As a further technical solution, a sealing groove is provided on the circumference of the cover plate 3 , and a sealing ring is provided in the sealing groove. The sealing ring is used to seal the gap between the cover plate 3 and the cleaning hole 4 .

[0059] Specifically, a sealing groove is circumferentially formed on the lower inclined surface of the cover plate 3. In this embodiment, the sealing groove of the cover plate 3 has a width of 1.7 mm and an average depth of 1 mm. The sealing ring is an O-ring with a diameter of 1.5 mm.

[0060] The method of using the split end scanning drum of the utility model is as follows:

[0061] When installing for the first time, install the O-ring into the sealing groove of the cover plate, install the cover plate into the slot position of the cylindrical body, fix the cam cover with the fixing bolts and fix the cover plate indirectly through the boss. The structure of the cam cover is as follows: Figure 11 、 Figure 12 As shown in the figure, the assembled end scanning drum is installed on the original drive shaft of the equipment.

[0062] When disassembling the end scanning drum, use a hexagonal wrench to loosen the fastening screws of the cam cover, remove the cam cover, and take down the cover of the cleaning hole. The schematic diagram of the cover removal and installation is as follows: Figure 13 、 Figure 14 As shown, the smoke dust inside the end scanning drum can be cleaned through the cleaning hole, and the installation is completed in reverse order.

[0063] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
