Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to a filter rod forming machine tow pre-lifting device. Background Technology

[0002] In the tobacco filter rod production process, the filter rod forming machine needs to guide, transport and regulate raw materials such as cellulose acetate tow through the tow pre-lifting device to ensure that the tow belt enters the subsequent forming process (such as forming paper wrapping, shredding, etc.) in a stable state. The performance of its core components, the guide roller and the baffle, directly affects the filter rod production efficiency and product quality.

[0003] However, the traditional disassembly of the guide roller requires the use of a wrench to remove the bolts and a bearing puller to separate the interference fit, which is cumbersome and time-consuming, resulting in a significant increase in equipment maintenance downtime. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pre-lifting device for the filament bundle of a filter rod forming machine, which aims to improve the problem that the traditional disassembly of the guide roller requires the use of a wrench to remove bolts and a bearing puller to separate the interference fit, which is cumbersome and time-consuming.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A filter rod forming machine fiber bundle pre-lifting device includes a bearing seat, a connecting seat fixedly connected inside the bearing seat, a first spring disposed inside the connecting seat, a sliding column disposed at one end of the first spring, a pull rod fixedly connected at one end of the sliding column, the pull rod being slidably connected to the outside of the connecting seat, a connecting block fixedly connected at the other end of the sliding column, a guide roller disposed outside the connecting block, and a locking component disposed inside the guide roller.

[0007] The above technical solution provides a fixed support for the connecting seat. The first spring, sliding column and pull rod inside the connecting seat cooperate. Pulling the pull rod can drive the sliding column to compress the first spring, causing the connecting block to disengage from the guide roller. Releasing the pull rod will cause the first spring to reset and push the sliding column, allowing the connecting block to fit against the guide roller. Then, the two are locked by the locking component inside the guide roller. No special tools are required, which simplifies the disassembly and assembly steps of the guide roller, shortens maintenance time and improves equipment operating efficiency.

[0008] Preferably, the locking assembly includes a plug rod, the outside of which is disposed inside the guide roller, a second spring is disposed inside the plug rod, one end of the second spring is disposed with a locking post, a limit groove is formed inside the plug rod, and a first locking groove is formed inside the connecting block.

[0009] Preferably, the locking assembly further includes a pressing block, the pressing block being slidably connected to the inside of the guide roller, a connecting plate being fixedly connected to the bottom end of the pressing block, a third spring being provided at the bottom end of the connecting plate, a buckle being fixedly connected to the outside of the connecting plate, and a second slot being provided inside the connecting block.

[0010] Preferably, the outer side of the locking post is slidably connected to the inside of the insert rod and the limiting groove, the outer side of the locking post is engaged with the outside of the guide roller, and the outer side of the insert rod is disposed inside the first locking groove.

[0011] Preferably, the external part of the connecting plate is slidably connected to the inside of the guide roller, and the external part of the buckle is engaged with the inside of the second slot.

[0012] Preferably, a worktable is fixedly connected to the bottom end of the bearing seat, an adjustment component is provided on the upper surface of the worktable, and a baffle is provided at the top of the adjustment component.

[0013] Preferably, the adjustment assembly includes an electric push rod, which is externally fixedly connected to the upper surface of the worktable. A slide rail is fixedly connected to the upper surface of the worktable. A slider is fixedly connected to the bottom end of the guide roller. A toothed plate is externally fixedly connected to the slider. Gears are meshed at the toothed ends of the toothed plate.

[0014] Preferably, the output end of the electric push rod is fixedly connected to the outside of the guide roller, the outside of the slider is slidably connected to the inside of the slide rail, the outside of the toothed plate is slidably connected to the outside of the slide rail, and the bottom end of the gear is rotatably connected to the upper surface of the worktable.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by pressing the pressing pin, it slides along the limiting groove and compresses the second spring, thus pulling the insert rod out from the first slot and the guide roller. Alternatively, by pressing the pressing block, the pressing block moves the connecting plate downward, and at the same time, the connecting plate compresses the third spring, thereby causing the connecting plate to move the buckle out of the second slot. Finally, by pulling the pull rod, the sliding column slides and compresses the first spring, while the connecting block disengages from the inside of the guide roller, and the guide roller can be pulled out to complete the disassembly. This eliminates the need for special tools, making the operation convenient, shortening the time for disassembling and maintaining the guide roller, and achieving the effect of improving the operating efficiency of the equipment.

[0017] 2. In this utility model, the electric push rod is activated to push the baffle to move, thereby causing the slider to slide along the slide rail. At the same time, the slider drives the toothed plate to move synchronously. Because the toothed plate meshes with the gear, the toothed plate drives the gear to rotate when it slides. When the baffle is in contact with the edge of the filament belt, the electric push rod stops working. The baffle restricts the lateral displacement of the filament belt, thus completing the width adjustment. In this way, the position of the baffle can be adjusted to achieve the effect of adapting to filament belts of different widths. Attached Figure Description

[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Example 1:

[0032] Reference Figures 1-3 An embodiment of this utility model provides a filter rod forming machine filament pre-lifting device, including a bearing seat 1, a connecting seat 2 fixedly connected inside the bearing seat 1, a first spring 3 provided inside the connecting seat 2, a sliding column 5 provided at one end of the first spring 3, a pull rod 4 fixedly connected at one end of the sliding column 5, the pull rod 4 being slidably connected to the outside of the connecting seat 2, a connecting block 6 fixedly connected at the other end of the sliding column 5, a guide roller 7 provided outside the connecting block 6, and a locking component 8 provided inside the guide roller 7;

[0033] Specifically, in this embodiment, the bearing seat 1 is used to provide fixed support for the overall guide roller 7 assembly, ensuring the structural stability. The connecting seat 2 is used to install the first spring 3 and the sliding column 5, and to provide guidance for the sliding column 5 to slide. The first spring 3 is used to push the sliding column 5 to move when the sliding column 5 is not under force. The sliding column 5 is used to drive the connecting block 6 to move. The pull rod 4 is used to facilitate the operator to pull the pull rod 4 to drive the sliding column 5 to move. The connecting block 6 is used to connect the guide roller 7, transmit the power of the sliding column 5 and provide the installation positioning reference for the guide roller 7. The guide roller 7 is used to directly contact and guide the yarn bundle to be transported to the subsequent process according to the preset path. The locking component 8 is used to lock the guide roller 7 and the connecting block 6 to prevent them from rotating relative to each other or separating during operation, ensuring the stable operation of the guide roller 7.

[0034] Reference Figures 3-5 The locking assembly 8 includes a rod 801, the outside of which is disposed inside the guide roller 7, a second spring 802 is disposed inside the rod 801, a locking post 803 is disposed at one end of the second spring 802, a limiting groove 804 is formed inside the rod 801, and a first locking groove 805 is formed inside the connecting block 6.

[0035] Specifically, in this embodiment, the insertion rod 801 is used to insert into the first slot 805 of the connecting block 6 to achieve initial positioning of the guide roller 7 and the connecting block 6. The second spring 802 is used to push the locking post 803 to move through elastic deformation, providing locking power for the locking post 803. The locking post 803 is used to lock onto the outside of the guide roller 7 under the push of the second spring 802, fixing the insertion rod 801 inside the guide roller 7 and preventing the insertion rod 801 from loosening. The limiting groove 804 is used to limit the sliding range of the locking post 803 to prevent the locking post 803 from coming out of the insertion rod 801. The first slot 805 is used to provide insertion space for the insertion rod 801, so that the insertion rod 801 can be fixed to the guide roller 7 and the connecting block 6 by inserting into the first slot 805, thereby simplifying the disassembly and assembly steps and achieving the effect of quick disassembly and assembly of the guide roller 7.

[0036] Example 2:

[0037] Reference Figures 7-9 The locking assembly 8 also includes a pressing block 806, which is externally slidably connected to the inside of the guide roller 7. A connecting plate 807 is fixedly connected to the bottom end of the pressing block 806. A third spring 808 is provided at the bottom end of the connecting plate 807. A buckle 809 is fixedly connected to the outside of the connecting plate 807. A second slot 810 is provided inside the connecting block 806. The external of the locking post 803 is slidably connected to the inside of the insertion rod 801 and the limiting groove 804. The external of the locking post 803 is engaged with the outside of the guide roller 7. The external of the insertion rod 801 is provided inside the first slot 805. The external of the connecting plate 807 is slidably connected to the inside of the guide roller 7. The external of the buckle 809 is engaged with the inside of the second slot 810.

[0038] Specifically, in this embodiment, the pressing block 806 is used to drive the connecting plate 807 to move synchronously when the operator presses the pressing block 806, providing power for the unlocking buckle 809. The connecting plate 807 is used to transmit the force of the pressing block 806 and drive the buckle 809 to move. The third spring 808 is used to push the connecting plate 807 and the pressing block 806 back to the initial position through elastic reset after the pressing block 806 is released. The buckle 809 is used to engage in the second slot 810 to lock the guide roller 7 and the connecting block 6. The second slot 810 is used to provide engagement space for the buckle 809, so that the guide roller 7 can be quickly disassembled and assembled, thereby reducing equipment downtime.

[0039] Example 3:

[0040] Reference Figure 1 and Figure 10The bottom end of the bearing seat 1 is fixedly connected to a worktable 9. An adjustment assembly is provided on the upper surface of the worktable 9, and a baffle 10 is provided at the top of the adjustment assembly. The adjustment assembly includes an electric push rod 11, which is fixedly connected to the upper surface of the worktable 9. A slide rail 12 is fixedly connected to the upper surface of the worktable 9. A slider 13 is fixedly connected to the bottom end of the guide roller 7. A toothed plate 14 is fixedly connected to the outside of the slider 13. A gear 15 is meshed with the toothed end of the toothed plate 14. The output end of the electric push rod 11 is fixedly connected to the outside of the guide roller 7. The outside of the slider 13 is slidably connected to the inside of the slide rail 12. The outside of the toothed plate 14 is slidably connected to the outside of the slide rail 12. The bottom end of the gear 15 is rotatably connected to the upper surface of the worktable 9.

[0041] Specifically, in this embodiment, the workbench 9 provides a mounting support base for the bearing seat 1 and the adjustment assembly, ensuring the stability of the overall structure. The adjustment assembly drives the baffle 10 to move to adapt to different widths of filament bundles. The baffle 10 limits the lateral offset of the filament bundles to prevent them from running off-center. The electric push rod 11 provides power for adjusting the position of the guide roller 7. The slide rail 12 provides a sliding guide for the slider 13, ensuring that the slider 13 drives the guide roller 7 to move smoothly in a preset direction. The slider 13 moves synchronously with the baffle 10 and simultaneously drives the toothed plate 14 to move. The toothed plate 14 meshes with the gear 15, driving the gear 15 to rotate. The gear 15 rotates under the drive of the toothed plate 14, which can drive the toothed plate 14 on the other side to move, thereby achieving the effect of adapting to the production of filament bundles of multiple specifications.

[0042] Working principle: When it is necessary to disassemble and assemble the guide roller 7, firstly, press the pressing pin 803 to make it slide along the limiting groove 804 and compress the second spring 802, and pull out the insertion rod 801 from the first slot 805 of the connecting block 6 and the guide roller 7. Alternatively, press the pressing block 806, which will drive the connecting plate 807 to move down. At the same time, the connecting plate 807 will compress the third spring 808, thereby causing the connecting plate 807 to drive the buckle 809 to disengage from the second slot 810 of the connecting block 6. Finally, pull the pull rod 4 to drive the sliding column 5 to slide and compress the first spring 3, while simultaneously causing the connecting block 6 to disengage from the inside of the guide roller 7. The guide roller 7 can then be pulled out to complete the disassembly. This can be done without the need for special tools, making the operation convenient, shortening the disassembly and maintenance time of the guide roller 7, and improving the operating efficiency of the equipment.

[0043] When it is necessary to adapt to different widths of filament bundles, firstly, the electric push rod 11 is activated to push the baffle 10 to move, thereby causing the slider 13 to slide along the slide rail 12. At the same time, the slider 13 drives the toothed plate 14 to move synchronously. Since the toothed plate 14 meshes with the gear 15, the toothed plate 14 drives the gear 15 to rotate when it slides. When the baffle 10 is in contact with the edge of the filament bundle, the electric push rod 11 stops working, and the baffle 10 restricts the lateral displacement of the filament bundle, thus completing the width adjustment. In this way, the position of the baffle 10 can be adjusted to achieve the effect of adapting to filament bundles of different widths.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
