Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette processing machinery technology, and in particular to a drum-gathering device and a cigarette rolling machine. Background Technology
[0002] With the modernization of filter cigarette manufacturing equipment, the rolling and packaging equipment are connected by auxiliary equipment to form a highly automated production line. This not only results in high production speed but also a fully functional cigarette quality inspection system. This places higher demands on the process control of cigarette production. In terms of cigarette length, if the deviation and variation value of the cigarette length are large, it will cause the detection device to make false detections, resulting in false rejections and missed rejections. This will not only allow unqualified cigarettes to enter the finished product but also cause a lot of waste due to false rejections. Therefore, it is essential to control the elements of each unit that makes up the filter cigarette during the manufacturing process to improve quality, increase operating efficiency, and reduce consumption.
[0003] The cigarette rolling machine starts with a receiving drum containing a double-length tobacco stick. On the first cutting wheel, this stick is cut into two equal-length single-length tobacco sticks. Then, on the separating drum, the tobacco sticks are pulled apart axially to accommodate a double-length filter. A double-length filter is then inserted into the space between the two single-length, unfiltered tobacco sticks, forming a three-section assembly: tobacco stick + filter + tobacco stick. On the combining wheel, this three-section assembly is brought together axially and its center is aligned with the center of the final cutter. A piece of glued cork paper is then attached to the three-section assembly. After rolling and twisting, a double-length filter cigarette is formed, which is finally cut into two equal-length filter cigarettes. The length of a filter cigarette is the sum of the filter length and the length of the unfiltered cigarette. To control the maximum deviation and variation in the length of the filter cigarette, the maximum deviation and variation in the length of both the filter and unfiltered cigarettes must be controlled within a certain range. Due to defects in existing cigarette length control devices and mechanisms, the limits and variations of the manufactured filter cigarettes are large, and the length of some filter cigarettes exceeds the standard, affecting product quality.
[0004] Therefore, there is an urgent need for a device to bring the drum closer together in order to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to provide a converging drum device and a cigarette rolling machine that can quickly and effectively adjust the midpoint of the cigarette to align with the final cutting center, thereby improving the quality of cigarette length.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] Firstly, a device for bringing together a drum is provided, comprising:
[0008] The adjustment assembly includes a support member, two levers, and two eccentric pushing structures. The two levers are disposed at both ends of the support member, one end of each lever is slidably disposed on the support member, and the other end of each lever is fixedly connected to the eccentric pushing structure.
[0009] The drum wheel is used to support long tobacco strips;
[0010] The system includes an air intake seat and a rotating shaft. The drum is axially mounted on the air intake seat and the rotating shaft, and both the air intake seat and the rotating shaft are connected to the drum. Of the two eccentric pushing structures, one is fitted onto the air intake seat and forms a gap with it, while the other is fitted onto the rotating shaft and forms a gap with it. The central axis of the eccentric pushing structure is set at an angle to the central axis of the drum, and the two eccentric pushing structures are close to each other on the side facing the cigarette and far apart on the side away from the cigarette.
[0011] As an optional technical solution for the aforementioned drum-approaching device, the eccentric pushing structure includes an eccentric sleeve, which is fixedly connected to the lever. The two eccentric sleeves are located on both sides of the drum wheel, and the eccentric sleeves are set at an angle to the central axis of the drum wheel.
[0012] As an optional technical solution for the aforementioned approaching drum device, the eccentric pushing structure further includes a rotating disk, which is sleeved on the eccentric sleeve, and the rotating disk and the eccentric sleeve are rotatably connected through a first bearing.
[0013] As an optional technical solution for the above-mentioned approaching drum device, the rotating disk includes a connecting sleeve and a disk body. The outer diameter of the disk body is larger than the outer diameter of the connecting sleeve. The connecting sleeve is sleeved on the outer periphery of the first bearing, and the disk body is fixedly disposed on the side of the connecting sleeve facing the drum wheel.
[0014] As an optional technical solution for the aforementioned approaching drum device, the adjustment assembly further includes an adjustment screw, which is arranged parallel to the support member. The adjustment screw is connected to two levers respectively, enabling the two levers to move closer or further apart. The adjustment screw is a bidirectional threaded rod.
[0015] As an optional technical solution for the aforementioned approaching drum device, the adjustment assembly further includes two adjustment screws, which are arranged parallel to the support member, and the two adjustment screws are correspondingly connected to the two levers.
[0016] As an optional technical solution for the aforementioned approaching drum device, the two adjusting screws have different lengths, and the adjusting ends of the adjusting screws are located at the same end of the support member.
[0017] As an optional technical solution for the aforementioned approaching drum device, the adjustment assembly further includes two adjustment blocks, which are correspondingly arranged and connected to the two levers. The adjustment blocks are threadedly connected to the adjustment screws, and the adjustment blocks are provided with through holes for the support member to pass through.
[0018] As an optional technical solution for the aforementioned approaching drum device, the support member includes a support rod and a positioning plate, with the positioning plate located at both ends of the support rod.
[0019] Secondly, this utility model also provides a cigarette rolling machine, including the approaching drum device described in any of the above embodiments.
[0020] This utility model has at least the following beneficial effects:
[0021] Since the central axes of the two eccentric pushing structures are set at an angle to the central axis of the drum, the two eccentric pushing structures move closer to each other on the side facing the cigarette and further away from each other on the side facing away from the cigarette. This pushes the position of the cigarette to adjust its position, ensuring that the center of the two eccentric pushing structures is aligned with the cutting center, thus improving the quality of the cigarette length.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. 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.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. 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] like Figures 1 to 4 As shown, this utility model proposes a converging drum device that can quickly and effectively adjust the midpoint of the cigarette to align with the final cutting center, thereby improving the quality of the cigarette length.
[0034] like Figure 1 and Figure 2As shown, the device includes an adjustment assembly, a drum 4, an air intake seat 5, and a rotating shaft 6. The adjustment assembly includes a support member 1, two levers 2, and two eccentric pushing structures 3. The two levers 2 are located at both ends of the support member 1, with one end of the lever 2 slidably mounted on the support member 1 and the other end fixedly connected to the eccentric pushing structure 3. The drum 4 is used to support the long tobacco stick. The drum 4 is axially mounted on the air intake seat 5 and the rotating shaft 6, and both the air intake seat 5 and the rotating shaft 6 are connected to the drum 4. Of the two eccentric pushing structures 3, one is fitted onto the air intake seat 5 and forms a gap with it, while the other is fitted onto the rotating shaft 6 and forms a gap with it. The central axis of the eccentric pushing structure 3 is set at an angle to the central axis of the drum 4, and the two eccentric pushing structures 3 are closer to each other on the side facing the tobacco stick and further apart on the side away from the tobacco stick.
[0035] Since the central axes of the two eccentric push structures 3 are set at an angle to the central axis of the drum 4, the sides of the two eccentric push structures 3 facing the cigarette are close to each other, and the sides away from the cigarette are far apart. This pushes the position of the cigarette to adjust its position, which ensures that the center of the two eccentric push structures 3 is aligned with the cutting center, thereby improving the length and quality of the cigarette.
[0036] like Figure 2 As shown, in some embodiments, the eccentric push structure 3 includes two eccentric sleeves 31 located on both sides of the drum 4, with the eccentric sleeves 31 forming an angle with the central axis of the drum 4. The eccentric sleeves 31 are fixedly connected to the lever 2, thereby enabling the eccentric sleeves 31 to move relative to the support member 1, thus ensuring that the two eccentric sleeves 31 move away from or closer to each other.
[0037] In some embodiments, such as Figure 2 and Figure 3 As shown, the eccentric push structure 3 also includes a rotating disk 32, which is sleeved on the eccentric sleeve 31, and the rotating disk 32 and the eccentric sleeve 31 are rotatably connected via a first bearing 33. The rotating disk 32 is used to directly contact the cigarette to push the cigarette to the center position, ensuring that the center of the cigarette is collinear with the cutting center of the drum 4, thereby ensuring the quality of the cigarette length. The rotating disk 32 and the eccentric sleeve 31 are rotatably connected via the first bearing 33, so that the rotating disk 32 can rotate relative to the eccentric sleeve 31, and thus can drive the rotating disk 32 to rotate during the rotation of the drum 4, which can avoid friction between the rotating disk 32 and the cigarette and affect the quality of the cigarette.
[0038] In some embodiments, the rotating disk 32 includes a connecting sleeve 321 and a disk body 322. The connecting sleeve 321 is sleeved on the outer periphery of the first bearing 33, and the disk body 322 is fixedly disposed on the side of the connecting sleeve 321 facing the drum 4. The disk body 322 is positioned facing the drum 4 to allow the disk body 322 to contact the cigarette, and the outer diameter of the disk body 322 is larger than the outer diameter of the connecting sleeve 321 to ensure that the disk body 322 can contact the cigarette and thus allow the cigarette to be pushed to adjust its position.
[0039] In some embodiments, the adjustment assembly further includes an adjustment screw 7, which is arranged parallel to the support member 1. The adjustment screw 7 is connected to two levers 2 respectively, enabling the two levers 2 to move closer or further apart. The adjustment screw 7 is a bidirectional threaded rod. When the adjustment screw 7 rotates, it enables the levers 2 to move closer or further apart, thereby achieving the purpose of clamping or releasing the cigarette. Since the distance between the two disc bodies 322 and the two sides of the drum 4 is fixed, the position of the cigarette can be adjusted.
[0040] In other embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the adjustment assembly also includes two adjusting screws 7, which are arranged parallel to the support member 1. Each adjusting screw 7 corresponds to and is connected to one of the two levers 2. The two adjusting screws 7 allow for individual adjustment of the positions of the two levers 2, thus enabling adjustment based on the position of different batches of cigarettes placed on the drum 4.
[0041] It should be noted that the two adjusting screws 7 are of different lengths, and the adjusting ends of the adjusting screws 7 are located at the same end of the support member 1. The different lengths of the two adjusting screws 7 can save manufacturing costs, while the fact that the adjusting ends of the adjusting screws 7 are located at the same end of the support member 1 facilitates the adjustment of the position of the lever 2 and prevents the other end of the support member 1 from being blocked by other structures, thus affecting the adjustment of the adjusting screws 7.
[0042] To secure the lever 2 to the support 1, the adjustment assembly also includes two adjustment blocks 8. Each adjustment block 8 corresponds to and is connected to one of the levers 2. The adjustment blocks 8 are fitted onto the support 1 and can slide along the axial direction of the support 1. The adjustment blocks 8 are threadedly connected to the adjustment screw 7, and each adjustment block 8 has a through hole through which the support 1 passes. The adjustment blocks 8 also have threaded holes that mate with the adjustment screw 7, and the adjustment screw 7 is threadedly connected to the threaded holes of the adjustment blocks 8.
[0043] For example, support member 1 includes a support rod and a positioning plate. The positioning plate has a through hole through which the adjusting screw 7 passes. The positioning plate is used to fix the support rod to the cigarette machine to support the support rod. The cross-section of the support rod is circular or polygonal. This ensures that the adjusting block 8 can move axially along the support rod.
[0044] The adjustment assembly also includes an adjustment disc 9, which is fixed to the end of the positioning disc opposite to the support rod. The adjustment screw 7 is threadedly connected to the adjustment disc 9 and supported by the adjustment disc 9. The positioning disc has a through hole for the adjustment screw 7 to pass through, and the through hole is oblong in shape.
[0045] This utility model also provides a cigarette rolling machine, including the converging drum device provided by this utility model.
[0046] Since the present invention includes the aforementioned converging drum device, the cigarette rolling machine of this utility model embodiment has all the advantages and beneficial effects of the above embodiments, which will not be repeated here.
[0047] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
