[0027] 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.

[0028] As Figures 2 to 4 shown, the embodiment of the present utility model provides a filter tip guide rail mounting structure, 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, a slide plate 72, and a mounting plate 71. The two connecting columns 61 are relatively arranged on the front side surface of the mounting plate 71. The front guide rail is parallel to the rear guide rail. Between the front guide rail and the rear guide rail, there are two guide rail columns 51 respectively corresponding to the two connecting columns; 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 61; the fixed seat includes a fixed plate 21 and a support block 22. The fixed plate is parallel to the front guide rail. The support block 22 is arranged on the front side surface of the fixed plate; the slide plate 72 is vertically arranged on the rear side surface of the mounting plate 71. A slide groove 74 is arranged on the bottom surface of the slide plate. The top surface of the support block has a support surface 23 for sliding cooperation with the slide groove 74. An installation screw hole 24 for cooperating with the threaded section of the locking screw is vertically arranged on the support surface. A U-shaped opening 73 for the threaded section of the locking screw to pass through is arranged on the left side of the slide plate 72.

[0029] The filter rod guide rail installation structure 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 pressing screws, a sliding plate and a mounting plate into a guide rail assembly as a whole; after the filter rod acceleration drum 81 is installed, by using the sliding fit between the sliding groove of the sliding plate and the supporting surface of the supporting block, the sliding plate slides leftward on the supporting surface, and after sliding to the installation position, the threaded section of the locking screw 31 passes through the U-shaped opening and is matched and fastened with the installation screw hole on the supporting block until the sliding plate is locked on the supporting block, that is, the installation of the guide rail assembly is completed; when it is necessary to disassemble the filter rod acceleration drum for maintenance, only need to loosen the locking screw 31 to release the locking of the sliding plate 72, without detaching the locking screw from the installation screw hole, and then make the sliding plate 72 slide rightward on the supporting surface of the supporting block until it is separated from the supporting block, that is, the disassembly of the guide rail assembly is completed, and then the filter rod acceleration drum can be disassembled. It can be seen that in the present utility model, every time the filter rod acceleration drum is maintained, only by tightening or loosening the locking screw to lock or release the locking of the sliding plate, the disassembly and assembly of the guide rail assembly can be conveniently realized, without disassembling and then installing the two guide rails, two guide rail columns, two connecting columns, and two pressing screws as in the prior art, saving the disassembly and assembly operations between the above-mentioned components, thereby effectively improving the maintenance efficiency of the filter rod acceleration drum and reducing the labor intensity of maintenance personnel.

[0030] Further, a limiting block 25 for blocking and connecting with the sliding plate is arranged on the left side of the top surface of the supporting block 22, so that the sliding plate can be limited by the limiting block 25, and the sliding plate can be better and firmly locked on the supporting block under the common limitation of the locking screw 31, the sliding groove and the limiting block 25.

[0031] Preferably, the top surface on the right side of the mounting plate 71 is flush with the top surface of the sliding plate 72, so as to facilitate the operation of loosening or tightening the locking screw.

[0032] It can be understood that each guide rail column is coaxial with each connecting column, and the guide rail column and the connecting column are both perpendicular to the front guide rail; the fixing plate is used to connect with the wall panel of the cigarette making machine, and the mounting plate and the supporting block are both parallel to the fixing plate.

[0033] Specifically, the supporting block 22 is detachably connected with the fixing plate 21.

[0034] Further, a connecting pipe 26 is provided between the fixing plate 21 and the supporting block 22. A threaded hole opposite to the pipe hole of the connecting pipe 26 is provided on the supporting block. A through hole 27 for a fixing screw to pass through is provided on the fixing plate, and the through hole is opposite to the pipe hole of the connecting pipe. With this solution, the threaded section of the fixing screw passes through the through hole and the pipe hole of the connecting pipe and then cooperates with the threaded hole and is tightened, so that the connection between the fixing plate and the supporting block can be realized. It can be understood that since there is a connecting pipe between the fixing plate and the supporting block, there is a gap between the two, so that a sliding space can be provided for the rear side wall of the sliding groove.

[0035] Specifically, the number of the connecting pipes 26 is two, and the two connecting pipes are oppositely arranged between the fixing plate 21 and the supporting block 22; the number of the threaded holes and the through holes 27 is two each. The two threaded holes are respectively opposite to the front ends of the pipe holes of the two connecting pipes 26, and the two through holes 27 are respectively opposite to the rear ends of the pipe holes of the two connecting pipes 26. With this solution, the connection between the fixing plate and the supporting block is realized by using two fixing screws, which can make the connection between the two more firm and reliable.

[0036] Preferably, the connecting pipe 26 is coaxial with the connecting column. One connecting pipe is located between the limiting block and the fixing plate, and the other connecting pipe is located between the fixing plate and the supporting block. The limiting block and the supporting block are of an integral structure; the sliding groove is a U-shaped groove with an opening vertically downward; the mounting plate 71 and the sliding plate 72 are of an integral structure.

[0037] When the utility model is in use, the sliding plate 72 can be placed on the supporting block 22 by relying on the sliding groove in advance, and the mounting plate is supported by the supporting block. Then, the front guide rail and the rear guide rail are adjusted according to the production standard requirements. After the adjustment is completed, the pressing screw is tightened to form a guide rail assembly. In this way, every time disassembly is required subsequently, only the locking screw needs to be loosened, and the guide rail assembly can be slid out to the right. During installation, only the guide rail assembly needs to be slid to the left until the sliding plate abuts against the limiting block, and then the locking screw is tightened.

[0038] The utility model assembles the front guide rail 41, the rear guide rail 42, two guide rail columns, two connecting columns, two pressing screws 43, a slide plate 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 slide plate are required, without the need to disassemble the front and rear guide rails, let alone 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 time-saving and labor-saving. At the same time, for each specification of the filter tip, a set of such installation structures can be made to achieve quick replacement without adjustment; and the utility model is convenient for disassembly, assembly and maintenance, effectively reducing the installation and debugging time and improving the maintenance efficiency.

[0039] 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.
