[0003] As Figure 1 shown, there are a front guide rail 14 and a rear guide rail 15 around the filter tip acceleration drum 11. Their functions are to facilitate the taking out of the filter tip from the straightening drum and ensure the conveyance of the filter tip 12 on the upper half of the filter tip acceleration drum. During the daily maintenance of the filter tip acceleration drum, before disassembling the filter tip acceleration drum 11, it is necessary to remove the front guide rail 14, the rear guide rail 15, two compression screws 13, two connecting columns 17 and two guide rail columns 16. After the maintenance of the filter tip acceleration drum is completed, it is necessary to install the two guide rail columns 16 between the two guide rails by using the two compression screws 13, install the two guide rail columns on the two connecting columns respectively, and install the two connecting columns 17 on the fixing plate 18 to complete the entire maintenance operation of the filter tip acceleration drum. This results in a relatively long maintenance time for the filter tip acceleration drum, a relatively high labor intensity for the maintenance personnel, and a relatively low maintenance efficiency. Therefore, how to improve the maintenance efficiency of the filter tip acceleration drum and reduce the labor intensity of the maintenance personnel has become a technical problem urgently to be solved by those skilled in the art.

[0007] Preferably, the sliding part is a long strip-shaped slider having the same extending direction as the U-shaped chute.

[0008] Preferably, the sliding part is a positioning post; the number of the positioning posts is two, and the two positioning posts are oppositely arranged on the rear side of the mounting plate.

[0009] Preferably, a first notch is formed in the upper right part of the supporting block, a second notch is formed in the upper right part of the mounting plate, the bottom surface of the second notch is flush with the lower side surface of the U-shaped chute, and the left side surface of the first notch is flush with the left side surface of the second notch; the U-shaped chute is arranged close to the bottom surface of the first notch, and the sliding part is arranged close to the left side surface of the second notch.

[0010] Preferably, the number of the mounting holes and the mounting screw holes is two, and the two mounting screw holes are opposite to the two mounting holes one by one.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the following will further introduce the solution in detail in combination with specific embodiments.

[0030] As Figures 2 to 5 shown, the embodiment of the present utility model provides an installation structure for a filter acceleration drum guide rail, which includes a guide rail assembly, a fixed seat, and a locking screw 31. The guide rail assembly includes a front guide rail 41, a rear guide rail 42, two guide rail columns 51, two connecting columns 61, two compression screws 43, and a mounting plate 71. The two connecting columns are relatively arranged on the front side surface of the mounting plate. The front guide rail is parallel to the rear guide rail, and two guide rail columns corresponding to the two connecting columns are arranged between the front guide rail and the rear guide rail; after the threaded sections of the two compression screws respectively pass through the front guide rail, the two guide rail columns, and the rear guide rail, they are matched with the central screw holes of the two connecting columns; the fixed seat includes a fixed plate 21 and a support block 22. The fixed plate is parallel to the front guide rail, and the support block is arranged on the front side surface of the fixed plate; an upper part of the front side surface of the support block is provided with a U-shaped chute 23 extending horizontally in the left-right direction, and the opening of the U-shaped chute 23 faces right. A sliding part that is slidably matched with the U-shaped chute 23 is provided on the rear side surface of the mounting plate; a lower part of the front side surface of the support block 22 is provided with a mounting screw hole for cooperating with the threaded section of the locking screw, and a mounting hole 72 for allowing the threaded section of the locking screw to pass through is provided on the mounting plate 71, and the mounting hole 72 is opposite to the mounting screw hole.

[0031] The installation structure for the filter tip acceleration drum guide rail provided by the embodiment of the present utility model, before use, assembles the front guide rail, rear guide rail, two guide rail columns, two connecting columns, two compression screws and the mounting plate into a guide rail assembly as a whole; after the installation of the filter tip acceleration drum after maintenance is completed, insert the sliding part of the mounting plate into the U-shaped chute 23 of the support block, and make the sliding part slide leftward in the U-shaped chute 23. After sliding to the installation position, the mounting screw holes on the support block are opposite to the mounting holes on the mounting plate, and the threaded section of the locking screw passes through the mounting hole and is matched with the mounting screw hole and tightened until the mounting plate is locked on the support block, that is, the installation of the guide rail assembly is completed; when it is necessary to disassemble the filter tip acceleration drum for maintenance, only need to remove the locking screw 31 to release the locking of the mounting plate, and then make the sliding part slide rightward in the U-shaped chute until it disengages from the support block, that is, the disassembly of the guide rail assembly is completed, and then the filter tip acceleration drum can be disassembled. It can be seen that in the present utility model, every time the filter tip acceleration drum is maintained, only by disassembling and assembling the locking screw to lock or release the locking of the mounting plate, the disassembly and assembly of the guide rail assembly can be conveniently realized, without having to disassemble and then install the two guide rails, two guide rail columns, two connecting columns and two compression screws as in the prior art, saving the disassembly and assembly operations between the above-mentioned components, thereby effectively improving the efficiency of the maintenance operation of the filter tip acceleration drum and reducing the labor intensity of the maintenance personnel.

[0032] As Figure 2 shown, in an embodiment provided by the present utility model, the sliding part is a long strip-shaped slider 74 having the same extending direction as the U-shaped chute. Adopting this solution, when the left side surface of the long strip-shaped slider abuts against the left side surface of the U-shaped chute, the mounting plate slides to the installation position, and at this time the mounting hole is opposite to the mounting screw hole; at the same time, by using the cooperation between the long strip-shaped slider 74 and the U-shaped chute 23, it can effectively prevent the mounting plate from tilting during sliding, and the long strip-shaped slider can also provide good support for the mounting plate.

[0033] As Figure 3 shown, in another embodiment provided by the present utility model, the sliding part is a positioning post 75; the number of the positioning posts is two, and the two positioning posts are oppositely arranged on the rear side surface of the mounting plate. Adopting this solution, when the positioning post on the left abuts against the left side surface of the U-shaped chute, the mounting plate slides to the installation position, and at this time the mounting hole is opposite to the mounting screw hole; at the same time, the two positioning posts can provide good support for the mounting plate and can also prevent the mounting plate from tilting during sliding. It can be understood that at this time, the two positioning posts are oppositely arranged on the rear side surface of the mounting plate in the left-right direction.

[0034] In yet another embodiment, the number of positioning posts 75 can be one. At this time, by sliding the positioning post in the U-shaped sliding groove 23, it is possible to provide guidance for the movement of the mounting plate and facilitate determining whether the mounting plate has moved to the mounting position. That is, when the positioning post abuts against the left side surface of the U-shaped sliding groove, the mounting plate has reached the mounting position. Aligning the mounting holes with the mounting screw holes allows the mounting plate to be fixed to the support block using locking screws.

[0035] Furthermore, the upper right part of the support block 22 has a first notch, the upper right part of the mounting plate 71 has a second notch, the bottom surface of the second notch is flush with the lower side surface of the U-shaped sliding groove 23, and the left side surface 24 of the first notch is flush with the left side surface 73 of the second notch; the U-shaped sliding groove is arranged near the bottom surface of the first notch, and the sliding part is arranged near the left side surface of the second notch. With this solution, the weights of the support block and the mounting plate can be effectively reduced, saving raw materials.

[0036] Preferably, the number of both the mounting holes 72 and the mounting screw holes is two, and the two mounting screw holes correspond to the two mounting holes 72 one by one. With this solution, the connection between the mounting plate and the support block is realized using two locking screws, making the connection between the two more firm and reliable. At this time, the two mounting holes 72 can be arranged opposite to each other in the vertical direction on the mounting plate 71.

[0037] Specifically, the support block 22 is detachably connected to the fixing plate 21, facilitating the replacement or repair of the support block. Preferably, the support block and the fixing plate are connected by two fixing screws to make the connection between the two more firm and reliable. In one embodiment, a connecting rod 25 can be arranged between the support block and the fixing plate, and the fixing screw passes through the fixing plate and the connecting rod and is threadedly connected to the support block.

[0038] It can be understood that each guide rail column is coaxial with each connecting column, and both the guide rail column and the connecting column are perpendicular to the front guide rail; the fixing plate 21 is used to be connected to the wall panel of the cigarette machine, and the mounting plate and the support block are both parallel to the fixing plate. The connecting column can be threadedly connected to the mounting plate;

[0039] When the present utility model is in use, the sliding part of the mounting plate can be placed in the U-shaped sliding groove of the support block in advance, and the U-shaped sliding groove is used to support the mounting plate. Then, the front guide rail and the rear guide rail are adjusted according to the production standard requirements. After the adjustment is completed, the compression screw is tightened to form a guide rail assembly. In this way, every time it needs to be disassembled subsequently, only the locking screw 31 needs to be disassembled, and the guide rail assembly can be slid out to the right along the U-shaped sliding groove 23. During installation, it only needs to slide the guide rail assembly to the left until the sliding part abuts against the left side surface of the U-shaped sliding groove 23 to reach the installation position, and then the locking screw 31 is tightened.

[0040] The utility model assembles a front guide rail 41, a rear guide rail 42, two guide rail columns, two connecting columns, two pressing screws 43 and a mounting plate into a guide rail assembly as a whole. Before installation, only the front guide rail and the rear guide rail need to be adjusted once according to the production standard requirements. After that, every time the filter tip accelerating drum is disassembled, only the disassembly and assembly between the support block and the guide rail assembly are required, without the need to disassemble the front and rear guide rails, and there is no need to adjust the two guide rails again. However, in the prior art, since the two guide rails are disassembled, the two guide rails need to be adjusted every time the filter tip accelerating drum is overhauled. It can be seen that, compared with the prior art, the utility model preferably omits the step of adjusting the two guide rails every time, thus making the overhaul operation of the filter tip accelerating drum 81 more time-saving and labor-saving. At the same time, for each specification of the filter tip 82, a set of such an installation structure can be made to achieve the purpose of quick replacement without adjustment; and the utility model is convenient for disassembly, installation and maintenance, effectively reducing the installation and commissioning time and improving the efficiency of the overhaul operation.

[0041] The above are only the preferred embodiments of the utility model. It should be noted that these embodiments are only used to illustrate the utility model and not to limit the scope of the utility model. Moreover, after reading the content of the utility model, those skilled in the relevant art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.
