Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cigarette shredding equipment, and in particular to an upper copper busbar chain assembly for a feeding system of a shredding machine. Background Technology
[0002] The feeding system of the SD-EVO type shredder mainly consists of an upper copper busbar assembly, a lower copper busbar assembly, and a hopper. The upper and lower copper busbar assemblies are positioned vertically opposite each other, with their ends tilted towards their center to cooperate with the wedge-shaped channels formed by the left and right wall plates of the support. This allows the tobacco material to be conveyed via the upper and lower copper busbars. With the help of corresponding pressing and compacting components, the material is gradually squeezed and compacted as it moves towards the narrowing ends of the upper and lower copper busbar assemblies, forming a tobacco cake, which is then continuously cut by the cutter roller to form shreds.
[0003] However, for the upper copper busbar assembly, during the process of the upper and lower copper busbar assemblies working to transport and compress tobacco material, the tobacco material will in turn exert a force on the upper copper busbar assembly. In addition, due to the long-term operation of the upper copper busbar, the upper copper busbar will gradually loosen, resulting in a deterioration in the material conveying effect.
[0004] In addition, when the upper copper busbar chain becomes loose, the tension of the upper and lower copper busbar chains will be inconsistent, which will cause the upper copper busbar chain to deviate and rub against the side wall panels, causing wear. It will also cause the tobacco material to be conveyed off-center, and then get caught in the gap between the upper copper busbar chain and the side wall, jamming the upper copper busbar chain and affecting the overall stability of the material conveying of the shredder. Utility Model Content
[0005] To address the aforementioned technical deficiencies in the existing technology, this utility model provides an upper copper busbar chain assembly for a feeding system of a shredder. By incorporating a swingable conveyor roller and an intermediate adjusting component that can extend or shorten to drive the conveyor roller to swing, the tension of the upper copper busbar chain can be effectively adjusted, ensuring stable operation of the upper copper busbar chain assembly and effectively cooperating with the lower copper busbar chain assembly to transport tobacco materials.
[0006] The technical solution of this utility model to solve the above problems is: to provide an upper copper busbar chain assembly for a feeding system of a shredder, including a first conveyor roller, a second conveyor roller, an upper copper busbar chain, a first bracket, a second bracket, and a drive motor; the first conveyor roller is disposed on the first bracket, the second conveyor roller is disposed on the second bracket, the upper copper busbar chain is disposed between the first conveyor roller and the second conveyor roller, the drive motor is drivenly connected to the first conveyor roller or the second conveyor roller, the second bracket is rotatably connected to the first bracket, and an adjustable intermediate adjusting member is also connected between the first bracket and the second bracket.
[0007] Furthermore, the drive motor is mounted on the first bracket and driven by the first conveyor roller, or mounted on the second bracket and driven by the second conveyor roller.
[0008] Furthermore, the intermediate adjusting component includes a first shaft, a second shaft, and a third sleeve. One end of the first shaft is connected to the first bracket, and the other end is provided with an external thread. One end of the second shaft is connected to the second bracket, and the other end is also provided with an external thread. The inner wall of the third sleeve is provided with an internal thread that matches the external thread so as to be threadedly connected to both shafts.
[0009] Furthermore, the external thread on the first shaft has the opposite direction of rotation to the external thread on the second shaft, and the internal thread on the inner wall of the third sleeve is also configured as two sets of internal threads with opposite directions of rotation.
[0010] Furthermore, the two sets of internal threads with opposite directions provided on the inner wall of the third sleeve are divided at the middle of the third sleeve.
[0011] Furthermore, a spherical bearing is provided at the end of the first shaft that is connected to the first bracket, and the first shaft is connected to the first bracket through the spherical bearing; a spherical bearing is also provided at the end of the second shaft that is connected to the second bracket, and the second shaft is also connected to the second bracket through the spherical bearing.
[0012] Furthermore, a first locking nut is provided on the threaded connection end of the first shaft, and a second locking nut is provided on the threaded connection end of the second shaft.

[0013] Furthermore, the cross-section of the outer wall of the third sleeve is polygonal.
[0014] Furthermore, a protective sleeve is provided on the outer side of the third sleeve.
[0015] Furthermore, it also includes a guide wheel, which is disposed on the first bracket and located below the second conveyor roller, with a portion of the guide wheel protruding outside the first bracket.
[0016] The beneficial effects of this utility model are:
[0017] 1. The second conveyor roller is mounted on the first bracket in a swing manner via the second bracket. The technician only needs to twist the third sleeve to extend or shorten the intermediate adjustment component, thereby pushing the second conveyor roller away from or closer to the first conveyor roller, thereby making the upper copper bus chain tensioned or relaxed.
[0018] 2. The force exerted on the second conveyor roller by the upper copper busbar chain due to its own tension and weight can be shared by the second bracket and the intermediate adjustment component, so as to reduce the resistance to the extension of the intermediate adjustment component, thereby reducing the probability of damage and stripping of the internal and external threads of the intermediate adjustment component.
[0019] In addition, locking nuts are provided on both the first and second shafts. The two locking nuts can cooperate with each other to further clamp the third sleeve, preventing the third sleeve from rotating without human intervention, which would cause the tension of the upper copper busbar chain to change during the conveying of tobacco materials. Moreover, in addition to the threaded connection between the third sleeve and the first and second shafts, the threaded connection between the two locking nuts and the first and second shafts can further share the pressure exerted on the entire intermediate adjustment component by the upper copper busbar chain due to its own tension and weight, thereby further reducing the probability of damage to the intermediate adjustment component.
[0020] 3. The two ends of the intermediate adjustment component are connected to the first bracket and the second bracket respectively through spherical bearings, so that the intermediate adjustment component can swing up and down accordingly when it is extended or shortened, thereby adapting to the arc swing trajectory of the second conveyor roller.
[0021] Fourth, a protective sleeve is also provided on the outside of the third sleeve to effectively isolate the threaded position of the intermediate adjusting part from the outside world, preventing dust and other impurities from entering the interior of the intermediate adjusting part and causing screwing blockage.

[0028] Please see Figures 1 to 3 A specific embodiment of this utility model provides an upper copper busbar chain assembly for a feeding system of a shredder, comprising a first conveyor roller 1, a second conveyor roller 2, an upper copper busbar chain 3, a first bracket 4, a second bracket 5, and a drive motor. The first conveyor roller 1 is rotatably mounted on the lower left end of the first bracket 4 via conventional ball bearings. The left end of the first bracket 4 is fixedly connected to the body of the shredder. The second conveyor roller 2 is rotatably mounted on the upper end of the second bracket 5 via conventional ball bearings. The lower end of the second bracket 5 is hinged to the right end of the first bracket 4. The upper copper busbar chain 3 is positioned between the first conveyor roller 1 and the second conveyor roller 2. The drive motor is fixedly mounted on the side of the second bracket 5 and is connected to the second conveyor roller 2 via a coupling and a bevel gear transmission mechanism. The drive motor drives the upper copper busbar chain 3 to move around the first conveyor roller 1 and the second conveyor roller 2 via the second conveyor roller 2, so that the upper copper busbar chain 3 cooperates with the lower copper busbar chain positioned below it to convey tobacco material to the left.
[0029] In this embodiment, refer to Figure 1 Although not shown in the figure, it can be understood that the lower copper busbar assembly is located below the upper copper busbar assembly 3 in this embodiment. The lower copper busbar assembly can be set horizontally or tilted to the lower right so that the height of the conveying channel of the lower copper busbar assembly and the upper copper busbar assembly gradually decreases to the left. This allows the upper and lower copper busbar assemblies to compress the tobacco material by means of the gradually decreasing channel during the process of conveying the tobacco material to the left.
[0030] It should be noted that: Please refer to Figures 1 to 3In this embodiment, an intermediate adjusting member 6 with adjustable length is also provided between the right end of the first bracket 4 and the upper end of the second bracket 5. In this way, the technician can adjust the overall length of the intermediate adjusting member 6 so that the intermediate adjusting member 6 can push or pull the second bracket 5 and swing around its hinge position with the first bracket 4, thereby providing an intermediate adjusting member 6 with adjustable length between the first bracket 4 and the second bracket 5.
[0031] In addition, the bevel gear transmission mechanism and the coupling are connected to each other in a conventional manner and are perpendicular to the drive motor in the lateral direction, and are coaxially fixedly connected to the second conveyor roller 2.
[0032] Further, please refer to Figure 3 In this embodiment, the intermediate adjusting member 6 achieves adjustable length extension and retraction through a helical feed principle. Specifically, the intermediate adjusting member 6 includes a first shaft 61, a second shaft 62, and a third sleeve 63; the inner wall of the axial through hole of the third sleeve 63 is provided with two sets of internal threads, which extend from the middle of the third sleeve 63 to both ends, and the two sets of internal threads rotate in opposite directions, so that when the third sleeve 63 is screwed, the first shaft 61 and the second shaft 62 can extend outward or retract inward simultaneously; the right end of the first shaft 61 is provided with an external thread adapted to the internal thread, and the first shaft 61 is screwed... The left end of the third sleeve 63 is provided with a spherical bearing 64, and the left end of the first shaft 61 is rotatably connected to the right end of the first bracket 4 through the spherical bearing 64. The left end of the second shaft 62 is provided with an external thread that matches the internal thread. The second shaft 62 is screwed to the right end of the third sleeve 63. The right end of the second shaft 62 is also provided with a spherical bearing 64, and the right end of the second shaft 62 is also rotatably connected to the upper end of the second bracket 5 through the spherical bearing 64.
[0033] Please see Figure 2 It should be noted that in this embodiment, there are two sets of intermediate adjustment members 6, and the two sets of intermediate adjustment members 6 are respectively located on the front and rear outer sides of the second support 5. The second conveying roller 2 is located inside the second support 5. The second conveying roller 2 can avoid the intermediate adjustment members 6 from interfering with each other.
[0034] Further, please refer to Figure 3In this embodiment, the cross-section of the outer wall of the third sleeve 63 is a regular hexagon. Technicians can use tools such as wrenches to tighten the third sleeve 63, thereby adjusting the overall length of the intermediate adjusting member 6. In addition, after the overall length of the intermediate adjusting member 6 is adjusted to the correct position, in order to prevent the length of the intermediate adjusting member 6 from changing again, a first locking nut 65 is screwed onto the first shaft 61, and a second locking nut 66 is screwed onto the second shaft 62. The first locking nut 65 and the second locking nut 66 can cooperate with each other to further clamp the third sleeve 63, thereby restricting the rotation of the third sleeve 63, ensuring that the length of the intermediate adjusting member 6 does not change after being adjusted to the correct position, and increasing the area of the threaded connection region to prevent damage to the threads.
[0035] Further, please refer to Figure 1 and Figure 2 In this embodiment, a protective sleeve 7 is also provided on the outer side of the third sleeve 63. The protective sleeve 7 is fitted and covers the outer side of the third sleeve 63 to prevent impurities such as tobacco shreds and tobacco dust from entering the threaded connection area, thereby increasing the twisting resistance of the third sleeve 63.
[0036] It should be noted that the outer side of the protective sleeve 7 is also radially threaded with an abutment bolt. The outer end of the abutment bolt is integrally provided with a hexagonal head for easy screwing, and the inner end extends into the protective sleeve 7. In this regard, the technician can first loosen the abutment bolt and slide the protective sleeve 7 laterally to expose the third sleeve 63, and then screw the third sleeve 63 to adjust the length of the intermediate adjusting member 6. Alternatively, the abutment bolt can be screwed so that its inner end is pressed against the outer wall of the third sleeve 63, thereby fixing the sleeve to cover the outside of the third sleeve 63 and preventing impurity particles from entering the threaded connection area of the intermediate adjusting member 6.
[0037] Further, please refer to Figure 1 and Figure 2 In this embodiment, a guide wheel 8 is rotatably provided at the junction of the first bracket 4 and the second bracket 5. The outer surface of the guide wheel 8 is smooth, and the lower right profile of the guide wheel 8 protrudes beyond the lower right end of the first bracket 4, so that no matter how the second conveyor roller 2 rotates, the upper copper busbar chain 3 will not be bumped by the lower right end of the first bracket 4.
[0038] Anything not mentioned above applies to existing technologies.
