Description

Technical Field

[0001] This utility model relates to the field of cigarette rolling machinery technology, and in particular to a centering adjustment tool and a cigarette rolling machine. Background Technology

[0002] The function of the cutting drum in a cigarette rolling machine is to cut tobacco strips that are twice the length into strips of the same length. A typical cutting drum includes a drum body, a front swing float, a rear swing float, a front roller, and a rear roller. The side wall of the drum body has an axially oriented tobacco-collecting groove, the length of which is equal to twice the length of a standard cigarette. This groove is used to hold the cigarettes. A slit is cut in the center of the groove. The front and rear swing floats are mounted on either side of the drum body and rotate with it.

[0003] The cigarette machine's cutting drum receives double-length tobacco strips from the front drum rollers. These strips are then axially pushed to the center of the cutting drum by the action of the front and rear swing floats, where they are cut into equal-length single-length tobacco strips by the drum's cutting blades. However, during production, variations in the length of the double-length tobacco strips and inconsistent lengths of the cut single-length strips frequently occur. This necessitates adjusting the distance between the front and rear swing floats to ensure that the distance from either float to the center of the drum's cutting slit equals the length of the single-length tobacco strip, allowing the double-length strips to pass smoothly and be cut from the center. This adjustment method is generally called centering adjustment. However, existing adjustment methods lack a benchmark and are complex, requiring repeated adjustments of the float positions to align the tobacco strip lengths, resulting in low efficiency, long downtime, and impacting production efficiency. Furthermore, the adjustment process relies heavily on personnel experience and lacks standardized tools, leading to unstable results and difficulty in meeting diverse production needs.

[0004] Therefore, it is necessary to design a centering adjustment tool and a cigarette rolling machine to solve the problems existing in the prior art. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

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.

[0033] The technical solution provided by this utility model will be described below with reference to the accompanying drawings and specific embodiments.

[0034] Combination Figures 1 to 4 As shown, this embodiment provides a centering adjustment tool. This device is applied to a cigarette rolling machine, which includes a cutting drum, a front swing float, and a rear swing float. A cigarette-receiving groove is axially formed on the outer wall of the cutting drum. The length of the cigarette-receiving groove is equal to twice the standard cigarette length, and a cutting groove is provided at the center of the cigarette-receiving groove so that the axial distance between the cutting groove and the end of the cigarette-receiving groove is equal to one standard cigarette length. The front swing float and the rear swing float are respectively located at both ends of the cigarette-receiving groove. Before a cigarette segment of twice the standard cigarette length is placed into the cigarette-receiving groove, the centering adjustment tool can first adjust the front swing float and the rear swing float to a suitable position so that the distance between the front swing float and the rear swing float is exactly equal to twice the standard cigarette length. This ensures that after the cigarette segment is placed into the cigarette-receiving groove, the cutter of the cutting drum can cut the cigarette segment into segments of one standard cigarette length at the middle position, thereby achieving standardized cigarette production, ensuring that the produced cigarettes are of equal length, and thus improving production quality.

[0035] Specifically, refer to Figure 1 , Figure 3As shown, the centering adjustment tool provided in this embodiment includes an adjustment component 1 and a rod 2. The adjustment component 1 includes a fixed rod 11, a first adjustment component 12, and a second adjustment component 13. The fixed rod 11 is fixedly mounted on a wall plate located on one side of the cutting drum, and the length extension direction of the fixed rod 11 is parallel to the axial direction of the cutting drum. The first adjustment component 12 and the second adjustment component 13 are slidably mounted on the fixed rod 11, and a front swing float and a rear swing float are provided between the first adjustment component 12 and the second adjustment component 13. The length of the rod 2 is equal to twice the length of a standard cigarette. A limiting boss 211 is provided around the middle of the rod 2. The rod 2 is used to be placed in the cigarette receiving groove, and the limiting boss 211 can be placed in the cutting groove.

[0036] With the above setup, before placing the tobacco stick segment into the tobacco receiving groove, the rod 2 can be used as an adjustment reference. The rod 2 is used to accurately position the tobacco stick segment within the groove. Then, the first adjustment component 12 and the second adjustment component 13 are dragged, causing the front and rear swing floats to move relative to each other. This allows the front and rear swing floats to abut against the ends of the rod 2, enabling them to be adjusted to the desired position more efficiently and stably. Specifically, the distance between the front and rear swing floats is equal to twice the standard cigarette length, effectively reducing the number of adjustments required. After the tobacco stick segment is placed into the receiving groove, the segment is centered within the groove under the limiting action of the front and rear swing floats, allowing the cutting blade to cut from the middle of the segment, ensuring consistent cigarette length and thus improving cigarette production efficiency.

[0037] In this embodiment, reference Figure 4 As shown, the rod body 2 includes a main rod portion 21 and end rods 22. A limiting boss 211 is provided at the middle position of the main rod portion 21. An end rod 22 is detachably connected to each end of the main rod portion 21. The distance between the end of the end rod 22 furthest from the main rod portion 21 and the limiting boss 211 is equal to one standard cigarette length, and the two end rods 22 are of the same length. This allows the end rods 22 of different lengths connected to the main rod portion 21 to be adjusted according to the length of the cigarette segment, thus adapting to the production needs of cigarettes of different standard lengths and greatly improving the applicability of this centering adjustment tool. For example, a screw 212 is provided at each end of the main rod portion 21, and the end rod 22 has a screw hole inside, allowing the main rod portion 21 to be detachably connected to the end rod 22 via a threaded connection. This connection is stable and convenient for disassembly and assembly, effectively shortening the adjustment time.

[0038] Specifically, refer to Figure 1As shown, the first adjustment assembly 12 includes a first support frame 121, a first adjusting screw 122, and a first rotation limiting member 123. The first support frame 121 is mounted on the fixed rod 11. One end of the first adjusting screw 122 is provided with a first threaded portion 1221, which is threadedly connected to the first support frame 121. The other end of the first adjusting screw 122 is rotatably inserted into the second adjustment assembly 13. The first rotation limiting member 123 is used to limit the relative rotation between the first support frame 121 and the fixed rod 11.

[0039] In specific operation, after the centering adjustment tool is installed on the cigarette machine, first ensure that the first adjustment component 12 and the second adjustment component 13 are in contact with the steel ring parts of the front swing float and the rear swing float, respectively. Then fix the fixing rod 11, which can be installed on the wall plate with screws. Then place the rod body 2 in the smoke receiving groove and position it between the front swing float and the rear swing float. Place the limiting boss 211 into the cutting groove. Then screw the first adjustment screw 122. While ensuring that the relative position of the first adjustment screw 122 and the fixing rod 11 along the axial direction remains unchanged, the first support frame 121 can slide smoothly along the axial direction on the fixing rod 11 until the first support frame 121 drives the front swing float to move smoothly to contact the end of the end rod 22. This allows for precise control of the movement distance of the front swing float, avoiding frequent adjustments due to excessive or insufficient single movement distance, and achieving the goal of improving adjustment efficiency.

[0040] Further, refer to Figure 2As shown, the outer circumferential surface of the first adjusting screw 122 provided in this embodiment is provided with a first scale tooth 1222, and the second adjusting component 13 is provided with a first through hole 1301. The first adjusting screw 122 is rotatably inserted into the first through hole 1301, and the inner sidewall of the first through hole 1301 is provided with a first slope. The first scale tooth 1222 is interference-fitted to the first slope. Through the above-mentioned setting of the first scale tooth 1222 and the first slope, when the first adjusting screw 122 rotates, the first scale tooth 1222 needs to cross the first slope in the first through hole 1301, thereby generating periodic resistance and forming a blocking sensation (i.e., a "click" sensation). The debugging personnel can judge the number of times the first scale tooth 1222 crosses the first slope by hearing the number of "click" sounds. In other words, the debugging personnel can design a first adjusting screw 122 with multiple first scale teeth 1222 and adjacent first scale teeth 1222 having the same spacing. The distance between each adjacent first scale tooth 1222 represents the rotation length of the first adjusting screw 122 around the fixed rod 11 axis when a "click" sound is heard. When combined with the pitch on the first threaded part 1221, the debugging personnel can know the displacement moved by the first support frame 121 driving the front swing float each time a "click" sound is heard. For example, in this embodiment, 10 first scale teeth 1222 are evenly arranged on the outer circumferential surface of the first adjusting screw 122, 10 first slopes are evenly arranged inside the first through hole 1301, and the pitch of the first adjusting screw 122 is set to 1mm. Each rotation of the first adjusting screw 122 can drive the first support frame 121 to move the front swing float by 0.1mm, thereby achieving high adjustment accuracy.

[0041] In this embodiment, the first rotation limiting member 123 is a key block. The key block is installed in the keyway of the fixed rod 11 and sandwiched between the first support frame 121 and the fixed rod 11, thereby ensuring the relative locking function between the fixed rod 11 and the first support frame 121. The structure is simple and easy to implement, effectively reducing the design cost of the first rotation limiting member 123.

[0042] In this embodiment, a first support arm 1211 is provided on one side of the first support frame 121 to stop on the front swing float, and a first rolling element 124 is provided on the first support arm 1211 at one end away from the first support frame 121. The first rolling element 124 is tactilely connected to the steel ring portion of the front swing float, thereby making the first adjusting component 12 roll contact with the front swing float, reducing the wear of the front swing float and extending its service life.

[0043] Specifically, refer to Figure 2As shown, the first rolling element 124 includes a first rolling bearing 1241 and a first mounting part 1242. The first rolling bearing 1241 is mounted on the first support arm 1211 via the first mounting part 1242. The rolling surface of the first rolling bearing 1241 contacts the steel ring portion of the front swing float. The first mounting part 1242 includes bolts and nuts, which allows the first rolling bearing 1241 to be detachably mounted on the first support arm 1211, ensuring the installation stability of the first rolling bearing 1241 and facilitating timely maintenance, upkeep, or replacement of the first rolling bearing 1241, thus providing continuous protection for the front swing float.

[0044] Specifically, refer to Figure 1 As shown, the second adjustment assembly 13 provided in this embodiment includes a fixed frame 131, a second adjusting screw 133, a second support frame 132, and a second rotation limiting member 134. The fixed frame 131 is fixedly mounted on the fixed rod 11, and a first support frame 121 and a second support frame 132 are respectively provided on both sides of the fixed frame 131. One end of the second adjusting screw 133 is provided with a second threaded portion 1331, which is threadedly connected to the fixed frame 131. The other end of the second adjusting screw 133 is rotatably limited and inserted into the second support frame 132. The second rotation limiting member 134 can limit the relative rotation between the second support frame 132 and the fixed rod 11.

[0045] Through the aforementioned second adjustment component 13, when it is necessary to adjust the position of the rear swing float so that it abuts against the end of the end rod 22, by turning the second adjustment screw 133, since the fixed frame 131 is fixedly mounted on the fixed rod 11, the fixed frame 131 will not move with the rotation of the second adjustment screw 133. Therefore, the second adjustment screw 133 can drive the second support frame 132 to slide smoothly along the axial direction on the fixed rod 11 until the second support frame 132 drives the rear swing float to move smoothly to contact the end of the end rod 22. This allows for precise control of the movement distance of the rear swing float, thus reducing the need for frequent adjustments of the rear swing float and further improving the adjustment efficiency of the centering adjustment tool. The aforementioned first adjustment component 12 and second adjustment component 13 have simple structures and simple adjustment processes. That is, the adjustment personnel only need to turn the first adjustment screw 122 and the second adjustment screw 133 respectively to achieve the purpose of adjusting the relative distance between the front and rear swing floats. The operation difficulty is significantly reduced, greatly reducing the reliance on the experience of the adjustment personnel.

[0046] Similar to the structure of the first adjusting screw 122, in this embodiment, the reference... Figure 2As shown, the outer circumferential surface of the second adjusting screw 133 is provided with a second scale tooth 1332, and the second support frame 132 is provided with a second through hole 1321. The second adjusting screw 133 is rotatably inserted into the second through hole 1321, and a second slope is provided on the inner side wall of the second through hole 1321. The second scale tooth 1332 and the second slope are interference-fitted. Through the above-mentioned arrangement of the second scale tooth 1332 and the second slope, the debugging personnel can also refer to the operating principle of the first adjusting screw 122 to accurately control the movement distance of the second support frame 132. In one embodiment, the second adjusting screw 133 has 10 second scale teeth 1332 evenly arranged on its outer circumferential surface, and 10 second slopes are evenly arranged inside the second through hole 1321. The pitch of the second adjusting screw 133 is also set to 1mm, so that every time the debugging personnel rotate the second adjusting screw 133, the second support frame 132 can drive the rear swing float to move by 0.1mm, thereby ensuring a high adjustment accuracy of the rear swing float.

[0047] Furthermore, in this embodiment, a second support arm 1322 for stopping on the rear swing float is provided on one side of the second support frame 132, and a second rolling element 135 is provided on the second support arm 1322 at one end away from the second support frame 132. The second rolling element 135 is tactilely connected to the steel ring portion of the rear swing float, so that the second adjusting component 13 makes rolling contact with the rear swing float, which can reduce the wear of the rear swing float and make the service life of the rear swing float longer.

[0048] Specifically, in this embodiment, the second rolling element 135 includes a second rolling bearing 1351 and a second mounting component 1352. The second rolling bearing 1351 is mounted on the second support arm 1322 via the second mounting component 1352. The rolling surface of the second rolling bearing 1351 contacts the steel ring portion of the rear swing float. The second mounting component 1352 includes bolts and nuts, which allows the second rolling bearing 1351 to be detachably mounted on the second support arm 1322. This ensures the installation stability of the second rolling bearing 1351 and facilitates maintenance of the second rolling bearing 1351, thereby further reducing the wear and tear on the rear swing float.

[0049] Specifically, in this embodiment, the fixing frame 131 includes a detachably connected fixing frame body 1311 and a first adjusting block 1312. The fixing frame body 1311 is fixedly mounted on the fixing rod 11, and both the fixing frame body 1311 and the first adjusting block 1312 have a first through hole 1301. The inner sidewall of the first through hole 1301 of the first adjusting block 1312 is provided with the first slope. The second threaded part 1331 is rotatably inserted into the first adjusting block 1312 and threadedly connected to the fixing frame body 1311. With the above configuration, when it is necessary to further improve the adjustment accuracy of the first adjusting component 12 for the front swing float, the adjustment personnel only need to remove the first adjusting block 1312 from the fixing frame body 1311 and replace it with a first adjusting block 1312 having more first slopes. The replacement is more convenient and avoids the need to replace the entire fixing frame 131, effectively reducing material loss.

[0050] Specifically, in this embodiment, the second support frame 132 includes a detachably connected support frame body 1323 and a second adjustment block 1324. The support frame body 1323 is slidably mounted on the fixed rod 11. Both the support frame body 1323 and the second adjustment block 1324 are provided with the second through hole 1321. The inner sidewall of the second through hole 1321 of the second adjustment block 1324 is provided with the second slope. The other end of the second adjustment screw 133 is provided with the second scale tooth 1332. The second scale tooth 1332 passes through the support frame body 1323 and is interference-fitted to the second slope. With the above settings, when it is necessary to further improve the adjustment accuracy of the second adjustment component 13 for the rear swing float, the adjustment personnel only need to remove the second adjustment block 1324 from the support frame body 1323 and replace it with a second adjustment block 1324 having more second slopes. This facilitates the adjustment of the adjustment accuracy of the second adjustment component 13, which is highly convenient. At the same time, it avoids replacing the entire second support frame 132, further reducing the material loss rate.

[0051] For example, in this embodiment, the support frame body 1323 and the second adjustment block 1324, and the fixed frame body 1311 and the first adjustment block 1312 are connected by threaded connection, which is not only safe and reliable, but also convenient to disassemble and assemble, and can effectively reduce the time and labor costs spent on disassembly and assembly.

[0052] This embodiment also provides a cigarette rolling machine, including the aforementioned cutting drum, front swing float, rear swing float, and centering adjustment tool. Since the rod 2 of the centering adjustment tool is provided with a limiting boss 211, and the length of the rod 2 is equal to twice the standard cigarette length, and the distance from the limiting boss 211 to the end of the rod 2 is equal to one standard cigarette length, after the rod 2 is placed in the cigarette receiving groove of the cutting drum, the rod 2 can replace the cigarette strip segment as the adjustment reference for the distance between the front and rear swing floats. Then, the positions of the front and rear swing floats on the fixed rod 11 are adjusted by the adjusting component 1, so that they can respectively abut against the two ends of the rod 2, thereby adjusting the front and rear swing floats so that their distance is equal to twice the standard cigarette length. After the tobacco strip is placed in the tobacco receiving groove, the center of the tobacco strip can be aligned with the cutting groove in the tobacco receiving groove under the limiting action of the front swing float and the rear swing float. This allows the tobacco strip to be cut equally from the middle to obtain cigarettes of uniform length. The cigarettes can then be transferred to the next process for winding.

[0053] By setting the aforementioned centering adjustment tool in the cigarette rolling machine, the cigarettes produced by the machine are made to have consistent lengths, ensuring production quality. During the adjustment process, the speed of debugging the front and rear swing floats can be accelerated, greatly reducing the number of debugging times and time, shortening downtime and the number of downtimes, ensuring production efficiency, and reducing reliance on the experience of debugging personnel. It is more universal, the debugging results are more stable, and it effectively avoids problems such as multiple rework.
