Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging technology, and in particular to a swing adjustment device. Background Technology

[0002] During the cigarette packaging process, aluminum foil is usually stored in rolls, so it has a certain thickness. When the outer aluminum foil is squeezed or the temperature changes, it will deform. This deformation will cause the aluminum foil to fluctuate during the transmission process, causing problems such as paper jams and edge curling in the cigarette packaging machine, which will affect normal packaging production.

[0003] To solve this problem, the deformed aluminum foil is usually removed manually, which not only affects production efficiency but also wastes packaging materials. Utility Model Content

[0004] The purpose of this utility model is to provide a swing adjustment device with a simple structure, which can improve the swing of the roll material, and has stable function, low cost, and is easy to use for large-scale modification.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The swing adjustment device includes:

[0007] A roll material roller is rotatable for conveying the roll material in the conveying direction. A straightening gear is provided at one end of the roll material roller, and the axis of the straightening gear is perpendicular to the axial direction of the roll material roller. The straightening gear is rotatably mounted on the packaging machine via a first mounting shaft, and the axial direction of the first mounting shaft coincides with the axis of the straightening gear.

[0008] The adjustment module includes a second mounting shaft and an adjustment gear. The adjustment gear is rotatably mounted on the packaging machine via the second mounting shaft. The axial direction of the second mounting shaft coincides with the axis of the adjustment gear. The first mounting shaft is parallel to the second mounting shaft. The adjustment gear meshes with the straightening gear for transmission.

[0009] As an optional technical solution for the swing adjustment device, the adjustment module further includes a reduction gear, a third mounting shaft, and a drive gear. The reduction gear is spaced apart from the adjustment gear and coaxially sleeved on the second mounting shaft. The second mounting shaft is fixedly connected to both the reduction gear and the adjustment gear, and is rotatably mounted on the packaging machine. The drive gear is rotatably mounted on the packaging machine via the third mounting shaft. The axial direction of the third mounting shaft coincides with the axis of the drive gear. The second mounting shaft and the third mounting shaft are parallel to each other, and the drive gear meshes with the reduction gear for transmission.

[0010] As an optional technical solution for the swing adjustment device, the third mounting shaft is equipped with a handwheel.

[0011] As an optional technical solution for the swing adjustment device, the swing adjustment device further includes a locking module, which includes a locking block and an elastic element.

[0012] As an optional technical solution for the swing adjustment device, the locking module further includes an unlocking block. One end of the unlocking block is slidably connected to the packaging machine. The sliding direction of the unlocking block is perpendicular to the compression direction of the elastic element. The other end of the unlocking block is provided with an unlocking ramp. The locking block is provided with a mating ramp. When the unlocking block moves towards the locking block, the unlocking ramp abuts against the mating ramp, so that the locking block moves away from the second mounting shaft or the third mounting shaft. The elastic element continues to compress. When the locking module is unlocked, the elastic element is in a second compression state.

[0013] As an optional technical solution for the swing adjustment device, the locking block is covered with a flexible material, which is used to contact the second mounting shaft or the third mounting shaft.

[0014] As an optional technical solution for the swing adjustment device, the locking module further includes a mounting part, which protrudes from the outer wall of the packaging machine and has a mounting groove. The locking block is slidably placed in the mounting groove in a direction perpendicular to the second mounting shaft or the third mounting shaft.

[0028] 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.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

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.

[0032] like Figures 1 to 4 As shown, this utility model discloses a swing adjustment device, including a roll material roller 100 and an adjustment module 300. The roll material roller 100 is mounted on the base of a packaging machine 900, located between an input drive wheel 910 and an output drive wheel 920. The input drive wheel 910 and the output drive wheel 920 are respectively connected to the upper and lower parts of the base, and serve as the input and output ends of the roll material, respectively, for controlling the direction of the roll material during transport. The roll material can be, for example, packaging material such as aluminum foil. The roll material roller 100 is rotatable to transport the roll material in the transport direction. One end of the roll material roller 100 is provided with a straightening gear 110, which serves as the output end of a gear pair. The axis of the straightening gear 110 is perpendicular to the axial direction of the roll material roller 100. The straightening gear 110 is rotatably mounted on the packaging machine 900 via a first mounting shaft 200, the axial direction of which coincides with the axis of the straightening gear 110. The adjustment module 300 includes a second mounting shaft 320 and an adjustment gear 310. The adjustment gear 310 is rotatably mounted on the packaging machine 900 via the second mounting shaft 320. The axial direction of the second mounting shaft 320 coincides with the axis of rotation of the adjustment gear 310. The first mounting shaft 200 is parallel to the second mounting shaft 320. The adjustment gear 310 is meshed with and driven by the straightening gear 110. The angular change of the straightening gear 110 improves the fluctuation amplitude of the roll material roller 100 and the roll material. The operator can quickly adjust the angle of the straightening gear 110 and the roll material roller 100 by rotating the second mounting shaft 320 and the adjustment gear 310 using the swing adjustment device. The angle adjustment of the roll material roller 100 is mainly achieved by using gear transmission, thereby improving the oscillation of the roll material. The structure is simple, the function is stable, the cost is low, and it is easy to retrofit and use on a large scale.

[0033] Specifically, the adjustment module 300 also includes a reduction gear 330, a third mounting shaft 340, and a drive gear 350. The reduction gear 330 is spaced apart from the adjustment gear 310 and coaxially sleeved on the second mounting shaft 320. The second mounting shaft 320 is fixedly connected to the reduction gear 330 and the adjustment gear 310 respectively. The second mounting shaft 320 is rotatably mounted on the packaging machine 900. The drive gear 350 is rotatably mounted on the packaging machine 900 through the third mounting shaft 340. The axial direction of the third mounting shaft 340 coincides with the shaft of the drive gear 350. The second mounting shaft 320 and the third mounting shaft 340 are arranged parallel to each other. The drive gear 350 and the reduction gear 330 are meshed and driven together. The reduction gear 330 and the adjusting gear 310 are coaxially arranged and can rotate synchronously. The outer diameter of the reduction gear 330 is larger than that of the adjusting gear 310, while the outer diameter of the driving gear 350 is smaller than that of the reduction gear 330. Therefore, by adding the reduction gear 330, compared to the direct meshing and transmission between the driving gear 350 and the adjusting gear 310, the unit adjustment amplitude of the straightening gear 110 can be reduced, and the adjustment accuracy can be improved. At the same time, it avoids the multi-wheel transmission caused by the direct meshing and transmission between the driving gear 350 and the adjusting gear 310, which would affect the service life of the adjusting module 300 and the straightening gear 110. For example, a clearance groove is started at a suitable position on the base of the packaging machine 900. The design of the clearance groove can prevent the excessively large reduction gear 330 from interfering with the surrounding structure.

[0034] In this embodiment, a rotating shaft bracket is provided on the back of the base of the packaging machine 900. The two ends of the second mounting shaft 320 and the third mounting shaft 340 are respectively rotatably mounted on both sides of the rotating shaft bracket. One end of the third mounting shaft 340 extends out of the rotating shaft bracket and is provided with a handwheel 360. The operator can rotate the third mounting shaft 340 by rotating the handwheel 360. The drive gear 350 on it drives the reduction gear 330 that meshes with it to rotate. The second mounting shaft 320 rotates so that the adjusting gear 310 drives the straightening gear 110 that meshes with it to rotate, thereby completing the angle adjustment of the roll shaft. The two pairs of gear pairs form a simple reducer to achieve precise adjustment of the angle of the straightening gear 110.

[0035] Optionally, the adjusting gear 310 is connected to the second mounting shaft 320 by a flat key. Similarly, the reduction gear 330 is connected to the second mounting shaft 320, and the main gear is connected to the third mounting shaft 340 by a flat key. The flat key connection is mainly used to transmit torque and limit the axial movement of each gear. It has the advantages of simple structure, convenient assembly and disassembly, and good centering.

[0036] Furthermore, the straightening gear 110 is set as a sector gear. Since the oscillation adjustment angle range of the roll shaft is limited in actual operation, a straightening window is opened on the base of the packaging machine 900. The first mounting shaft 200 is snapped into the middle of the straightening window. The central angle of the sector gear is sleeved on the first mounting shaft 200. The central angle of the sector gear is less than 180°, and it is ensured that the sector gear will never interfere with the inner wall of the straightening window during the process of fluctuation amplitude changes of the roll shaft and the roll on it.

[0037] like Figure 3 and Figure 4 As shown, after the straightening gear 110 completes the angle adjustment, in order to prevent the roll shaft from deflecting, the swing adjustment device also includes a locking module 400 for locking the swing adjustment device. The locking module 400 includes a locking block 410 and an elastic element 420. One end of the elastic element 420 is connected to the shaft bracket on the packaging machine 900, and the other end of the elastic element 420 is connected to the locking block 410. The locking force is provided by the elastic force of the elastic element 420. When the locking module 400 is locked, the elastic element 420 is in a first compressed state, and the locking block 410 can engage with the second mounting shaft 320 or the third mounting shaft 340.

[0038] Specifically, the locking module 400 also includes a mounting part 401, which protrudes from the outer wall of the rotating shaft bracket. The mounting part 401 is provided with a mounting groove. The locking block 410 is slidably placed in the mounting groove in a direction perpendicular to the second mounting shaft 320 or the third mounting shaft 340. The mounting groove limits the locking block 410. When the elastic member 420 is in the first compressed state, the locking block 410 can abut against the second mounting shaft 320 or the third mounting shaft 340 to prevent the second mounting shaft 320 or the third mounting shaft 340 from rotating.

[0039] Optionally, the contact surface between the locking block 410 and the second mounting shaft 320 or the third mounting shaft 340 is covered with a flexible material. The flexible material is used to contact the second mounting shaft 320 or the third mounting shaft 340, improve the friction of the contact surface, and protect the second mounting shaft 320 or the third mounting shaft 340.

[0040] In this embodiment, multiple mounting portions 401 are provided, and these multiple mounting portions 401 are centrally symmetrically arranged around the second mounting shaft 320 or the third mounting shaft 340. Locking blocks 410 are correspondingly arranged one-to-one with each mounting portion 401. The multiple locking blocks 410 are equidistant from the second mounting shaft 320 or the third mounting shaft 340, and can evenly abut against the second mounting shaft 320 or the third mounting shaft 340 from multiple directions, effectively locking and limiting the movement and ensuring that the locking force is evenly applied to the second mounting shaft 320 or the third mounting shaft 340, thus protecting the service life and locking effect of the swing adjustment device. For example, the shaft bracket is provided with two vertically symmetrical mounting portions 401, with two corresponding locking blocks 410 simultaneously abutting against the upper and lower sides of the second mounting shaft 320 or the third mounting shaft 340.

[0041] Furthermore, the locking module 400 also includes an unlocking block 430 for unlocking the locking module 400. One end of the unlocking block 430 is slidably connected to the packaging machine 900, and the sliding direction of the unlocking block 430 is perpendicular to the compression direction of the elastic element 420. The other end of the unlocking block 430 is provided with an unlocking ramp, and the locking block 410 is provided with a mating ramp. The unlocking block 430 moves towards the locking block 410, and the unlocking ramp abuts against the mating ramp, so that the locking block 410 moves away from the second mounting shaft 320 or the third mounting shaft 340. The locking block 410 is lifted up by the ramp to achieve unlocking. At the same time, the elastic element 420 continues to compress. When the locking module 400 is unlocked, the elastic element 420 is in a second compression state, and the handwheel 360 can be rotated to readjust the roll shaft.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
