Description

Technical Field

[0001] This application relates to the field of cigarette equipment technology, and in particular to a filter rod production apparatus. Background Technology

[0002] The cigarette production process is generally divided into the smoke-generating section and the smoking section. The smoking section, which is the filter rod, requires cutting the filter rod during manufacturing, followed by transfer and transportation of the cut filter rods. Freshly cut filter rods are relatively soft. To better prevent the fiber bundles within the filter rod from springing back and deforming, a certain amount of pressure needs to be applied during the transfer and transportation process, making the transport of the filter rod more stable.

[0003] However, applying too much or too little pressure to the filter rod can easily affect its structure and transport stability. Utility Model Content

[0004] Therefore, it is necessary to provide a filter rod production apparatus that can provide more stable pressure to the filter rod and ensure stable transport of the filter rod, in order to address the above problems.

[0005] This application provides a filter rod production apparatus, including a stage, a fixed bracket, and an adjustment assembly. The stage has a receiving groove for placing filter rods. The fixed bracket is fixedly connected to the stage. The adjustment assembly has an adjustment end and a limiting end disposed opposite to each other. The limiting end is located above the receiving groove in the vertical direction and is used to limit the filter rods within the receiving groove in the vertical direction. The adjustment end is movably connected to the fixed bracket in the vertical direction to adjust the distance between the limiting end and the receiving groove.

[0006] In some embodiments, the adjustment assembly includes a support assembly and a limiting brush. One end of the support assembly is movably connected to the fixed support along the vertical direction to form the adjustment end. The limiting brush is connected to the other end of the support assembly away from the fixed support to form the limiting end.

[0007] In some embodiments, the bracket assembly is rotatably connected to the fixed bracket to adjust the tilt angle of the limiting brush relative to the horizontal plane.

[0008] In some embodiments, a first adjustment hole is provided at one end of the bracket assembly connected to the fixed bracket, and the first adjustment hole extends along the longitudinal direction of the bracket assembly; a second adjustment hole is provided on the fixed bracket.

[0009] The adjustment assembly further includes a first nut and a first screw that cooperate with each other. The first screw passes through the first adjustment hole and the second adjustment hole in sequence. The first nut and the first screw are used to adjust the position of the bracket assembly along the vertical direction and to adjust the tilt angle of the limiting brush relative to the horizontal plane.

[0010] In some embodiments, the bracket assembly includes a first bracket and a second bracket arranged intersecting each other, with one end of the first bracket and the second bracket connected to the fixed bracket and the other end of the first bracket and the second bracket connected to the limiting brush;

[0011] The first adjustment hole is provided on the first bracket and the second bracket respectively, and the second adjustment hole extends along the longitudinal direction of the fixed bracket.

[0012] In some embodiments, the first bracket and the second bracket are respectively provided with a third adjustment hole at the end connected to the limiting brush, and the limiting brush is provided with a fourth adjustment hole corresponding to the third adjustment hole. The adjustment assembly also includes a second nut and a second screw that cooperate with each other, and the second screw passes through the corresponding third adjustment hole and the fourth adjustment hole in sequence.

[0013] In some embodiments, the limiting brush extends longitudinally in the horizontal direction, and each of the fourth adjusting holes is located at opposite ends of the limiting brush along the longitudinal direction of the limiting brush, and at least one of the fourth adjusting holes extends longitudinally along the limiting brush.

[0014] In some embodiments, the fixing bracket extends along the vertical direction and has a scale bar arranged along the vertical direction.

[0016] In some embodiments, the receiving groove extends horizontally, and the projection of the receiving groove in a plane perpendicular to its extension direction is V-shaped.

[0017] The filter rod production device described above places the cut filter rods into a receiving tank. The limiting end of the adjusting component can more stably limit the filter rods in the receiving tank. At the same time, by adjusting the position of the adjusting end relative to the fixed support in the vertical direction, the distance between the limiting end and the receiving tank in the vertical direction can be adjusted, thereby adjusting the pressure applied by the limiting end to the filter rod in the receiving tank, making the transportation process of the filter rod more stable.

[0026] See Figure 1 One embodiment of this application provides a filter rod production apparatus 100, including a stage 10, a fixed bracket 20, and an adjustment assembly 30. The stage 10 has a receiving groove 11 for placing filter rods, and the fixed bracket 20 is fixedly connected to the stage 10. The adjustment assembly 30 has an adjustment end 31 and a limiting end 32 disposed opposite to each other. The limiting end 32 is located above the receiving groove 11 in the vertical direction, used to limit the filter rods within the receiving groove 11 in the vertical direction. The adjustment end 31 is movably connected to the fixed bracket 20 in the vertical direction to adjust the distance between the limiting end 32 and the receiving groove 11.

[0027] Specifically, a filter rod can be placed in the receiving groove 11 by opening on the upper surface of the stage 10. The fixed bracket 20 serves as a connection between the stage 10 and the adjusting component 30. The fixed bracket 20 is first fixedly connected to the stage 10, and then the adjusting component 30 is fitted onto the fixed bracket 20 so that the adjusting component 30 is located above the stage 10 in the vertical direction.

[0028] Furthermore, the adjusting assembly 30 has an adjusting end 31 and a limiting end 32 disposed opposite to each other. The adjusting end 31 is connected to the fixed bracket 20 and is movable relative to the fixed bracket 20 in the vertical direction. The limiting end 32 extends downward relative to the adjusting end 31, such that the adjusting end 31 is located above the receiving groove 11 in the vertical direction.

[0029] When the adjusting end 31 moves downward relative to the fixed bracket 20, the limiting end 32 moves downward along with the adjusting end 31, shortening the distance between the limiting end 32 and the receiving groove 11 until the limiting end 32 contacts the filter rod in the receiving groove 11. At this time, the limiting end 32 can apply pressure to the filter rod from top to bottom, making the filter rod more stably located in the receiving groove 11.

[0030] If the pressure applied to the filter rod by the limiting end 32 is too great, the limiting end 32 may cause pressure on the surface of the filter rod, resulting in grooves or indentations on the filter rod. In this case, the adjusting end 31 can be moved upward a certain distance relative to the fixed bracket 20 to reduce the pressure of the limiting end 32 on the filter rod.

[0031] If the pressure applied to the filter rod by the limiting end 32 is too small, it may not be able to effectively suppress the rebound of the filaments in the filter rod, resulting in the roundness of the filter rod exceeding the specified range or longitudinal stripes appearing on the surface. In this case, the adjusting end 31 can be moved downward a certain distance relative to the fixed bracket 20, thereby increasing the pressure of the limiting end 32 on the filter rod.

[0032] Thus, the pressure applied to the filter rod can be adjusted flexibly and accurately through the above structure, making the structure of the filter rod more stable and achieving stable transportation of the filter rod.

[0033] In some embodiments, the adjustment assembly 30 includes a support assembly 33 and a limiting brush 34. One end of the support assembly 33 is movably connected to the fixed bracket 20 in a vertical direction to form an adjustment end 31. The limiting brush 34 is connected to the other end of the support assembly 33 opposite to the fixed bracket 20 to form a limiting end 32.

[0034] Specifically, the limiting brush 34 is connected to the fixed bracket 20 via the bracket assembly 33, enabling the limiting brush 34 to be stably positioned above the receiving groove 11. One end of the bracket assembly 33 is connected to the fixed bracket 20, and this end can move vertically relative to the fixed bracket 20 to form an adjustment end 31. The other end of the bracket assembly 33 is connected to the limiting brush 34, allowing the limiting brush 34 to be positioned vertically above the receiving groove 11, thereby forming a limiting end 32.

[0035] Furthermore, by adjusting the position of the support assembly 33 relative to the fixed support 20 in the vertical direction, the limiting brush 34 can be moved synchronously with it, thereby adjusting the distance between the limiting brush 34 and the receiving groove 11. In this way, the limiting brush 34 can press against the filter rod in the receiving groove 11 with appropriate pressure, achieving stable transportation of the filter rod.

[0036] In some embodiments, the bracket assembly 33 is rotatably connected to the fixed bracket 20 to adjust the tilt angle of the limiting brush 34 relative to the horizontal plane.

[0037] Specifically, the bracket assembly 33 can not only move vertically relative to the fixed bracket 20, but also rotate relative to the fixed bracket 20.

[0038] It should be noted that in actual production, the stage 10 and its receiving groove 11 may not be perfectly horizontal, but may be tilted to a certain extent relative to the horizontal plane. If the stage 10 is tilted, the limiting brush 34 may generate different pressures at different positions in the horizontal direction when it presses down on the filter rod.

[0039] However, the stage 10 is usually fixedly connected to the overall production equipment for filter rods, which is not convenient for adjustment. Therefore, the bracket assembly 33 can be rotated relative to the fixed bracket 20 to adjust the tilt angle of the limiting brush 34 relative to the horizontal plane, so that the limiting brush 34 can be kept relatively horizontal with the stage 10 and the receiving groove 11 on it, thereby applying more uniform pressure to the filter rods in the receiving groove 11.

[0040] In some embodiments, a first adjustment hole 35 is provided at one end of the bracket assembly 33 connected to the fixed bracket 20, and the first adjustment hole 35 extends along the longitudinal direction of the bracket assembly 33; a second adjustment hole 21 is provided on the fixed bracket 20. The adjustment assembly 30 further includes a first nut (not shown in the figure) and a first screw 36 that cooperate with each other. The first screw 36 passes through the first adjustment hole 35 and the second adjustment hole 21 in sequence. The first nut and the first screw 36 are used to adjust the position of the bracket assembly 33 in the vertical direction and to adjust the tilt angle of the limiting brush 34 relative to the horizontal plane.

[0041] Specifically, when the bracket assembly 33 is assembled with the fixed bracket 20, the first adjustment hole 35 and the second adjustment hole 21 are aligned, and then the first screw 36 is passed through the first adjustment hole 35 and the second adjustment hole 21 in sequence. Then the first nut is tightened onto the first screw 36 to achieve a stable connection between the bracket assembly 33 and the fixed bracket 20.

[0042] When it is necessary to adjust the position of the bracket assembly 33 in the vertical direction, loosen the first nut, then adjust the position of the first screw 36 in the first adjustment hole 35 so that the bracket assembly 33 and the limiting brush 34 are at a suitable height, and then tighten the first nut.

[0043] Furthermore, the first nut, the first screw 36, the first adjusting hole 35, and the second adjusting hole 21 cooperate with each other to enable the bracket assembly 33 to rotate relative to the fixed bracket 20. That is, an external force is applied to rotate the bracket assembly 33 relative to the fixed bracket 20 by a certain angle, and then the first nut is tightened onto the first screw 36, thereby fixing the bracket assembly 33 at that angle.

[0044] In some embodiments, the bracket assembly 33 includes a first bracket 37 and a second bracket 38 that are arranged intersectingly. One end of the first bracket 37 and the second bracket 38 are connected to the fixed bracket 20, and the other end of the first bracket 37 and the second bracket 38 are connected to the limiting brush 34. The first bracket 37 and the second bracket 38 are respectively provided with a first adjustment hole 35, and the second adjustment hole 21 extends along the longitudinal direction of the fixed bracket 20.

[0045] It should be noted that, in order to facilitate the transport of filter rods, the receiving groove 11 is usually designed as a long strip-shaped groove that extends along the transport direction of the filter rods. In order to enable the limiting brush 34 to better provide pressure to the filter rods in the receiving groove 11, the limiting brush 34 is usually also designed as a rectangle, with its longitudinal direction consistent with the transport direction of the filter rods.

[0046] Therefore, to make the connection between the limiting brush 34 and the fixed bracket 20 more stable, a first bracket 37 and a second bracket 38 can be provided. One end of the first bracket 37 and the second bracket 38 are connected to the fixed bracket 20, and the other end is connected to the opposite ends of the limiting brush 34 along the longitudinal direction. That is, the first bracket 37, the second bracket 38 and the limiting brush 34 together form a triangle, which makes the structure more stable.

[0047] Furthermore, the fixed bracket 20 extends vertically and connects the first bracket 37, the second bracket 38, and the stage 10. The second adjustment hole 21 on the fixed bracket 20 extends along the longitudinal direction of the fixed bracket 20. Thus, by aligning the first adjustment hole 35 on the first bracket 37, the first adjustment hole 35 on the second bracket 38, and the second adjustment hole 21 on the fixed bracket 20 in sequence, and inserting the first screw 36, a stable connection can be achieved between the first bracket 37, the second bracket 38, and the fixed bracket 20.

[0048] Furthermore, by adjusting the specific position of the first screw 36 within the second adjustment hole 21, the included angle between the first bracket 37 and the second bracket 38 can be changed, thereby changing the vertical height of the limiting brush 34 through the first bracket 37 and the second bracket 38, ultimately adjusting the distance between the limiting brush 34 and the receiving groove 11.

[0049] In some embodiments, the first bracket 37 and the second bracket 38 are respectively provided with a third adjustment hole (not shown in the figure) at the end connected to the limiting brush 34, and a fourth adjustment hole (not shown in the figure) is provided on the limiting brush 34 corresponding to the third adjustment hole. The adjustment assembly 30 also includes a second nut 39 and a second screw (not shown in the figure) that cooperate with each other, and the second screw passes through the corresponding third adjustment hole and the fourth adjustment hole in sequence.

[0050] Specifically, the first bracket 37, the second bracket 38 and the limiting brush 34 can be stably connected by the second screw and the second nut 39, and the corresponding limiting brush 34 can be replaced more flexibly.

[0051] In some embodiments, the limiting brush 34 extends longitudinally in the horizontal direction, and each fourth adjustment hole is located at opposite ends of the limiting brush 34 along the longitudinal direction of the limiting brush 34, and at least one fourth adjustment hole extends along the longitudinal direction of the limiting brush 34.

[0052] Specifically, the longitudinal extension direction of the limiting brush 34 is consistent with the extension direction of the receiving groove 11, that is, consistent with the transport direction of the filter rod. A fourth adjustment hole is provided at each of the opposite ends of the limiting brush 34 along its own longitudinal direction, and the fourth adjustment hole extends along the longitudinal direction of the limiting brush 34.

[0053] Furthermore, a pair of second screws and second nuts 39 are provided in each third adjustment hole and its corresponding fourth adjustment hole. In this way, the distance between one end of the limiting brush 34 and the receiving groove 11 can be adjusted by adjusting the position of one of the second screws in the corresponding fourth adjustment hole.

[0054] For example, when the pressure applied to the filter rod by the two opposite ends of the limiting brush 34 along the longitudinal direction is unequal, the position of the second screw at one end corresponding to the fourth adjusting hole can be adjusted. At this time, since the ends of the first bracket 37 and the second bracket 38 connected to the fixed bracket 20 remain stationary, if the horizontal position of the other end of either the first bracket 37 or the second bracket 38 changes, it will cause the corresponding end of the limiting brush 34 to move vertically. This allows for better adjustment of the two ends of the limiting brush 34, making the pressure applied to the filter rod more uniform.

[0055] In addition, to further improve the adjustment accuracy of the second screw and the second nut 39, a scale can be added to the second screw or the second nut 39 to better control the adjustment accuracy.

[0056] In some embodiments, the fixing bracket 20 extends in a vertical direction and has a scale bar 22 arranged in a vertical direction.

[0057] Specifically, the fixed bracket 20 extends vertically, with its upper end connected to the first bracket 37 and the second bracket 38, and its lower end fixedly connected to the platform 10.

[0058] Furthermore, a vertical scale bar 22 is provided on the fixed bracket 20, through which the vertical movement distance of the first bracket 37 and the second bracket 38 can be observed, thereby enabling more precise adjustment of the positions of the first bracket 37 and the second bracket 38.

[0059] In some embodiments, the fixed bracket 20 and the platform 10 are connected by a snap-fit ​​connection. This allows for a detachable connection between the fixed bracket 20 and the platform 10, ensuring a stable connection and facilitating operation.

[0060] In some embodiments, the receiving groove 11 extends horizontally, and the projection of the receiving groove 11 into a plane perpendicular to its extending direction is V-shaped. Thus, when the filter rod is placed in the receiving groove 11, the V-shaped receiving groove 11 can better confine the filter rod within it, achieving stable transport of the filter rod.

[0061] According to one or more embodiments, when this application is used, the cut filter rods are first placed in the receiving groove 11, and then the pressure applied to the filter rods by the limiting brush 34 is adjusted by adjusting the position of the first support 37 and the second support 38 in the vertical direction.

[0062] Furthermore, the tilt angle of the limiting brush 34 relative to the horizontal plane can be adjusted by adjusting the tilt angle of the first bracket 37 and the second bracket 38, so that the limiting brush 34 can be better set parallel to the receiving groove 11.

[0063] In addition, the pressure applied to the filter rod by the two ends of the limiting brush 34 can be adjusted in a targeted manner by adjusting the height of the two ends of the limiting brush 34 in the vertical direction, so that the pressure applied to the filter rod by the limiting brush 34 is more uniform.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
