Description

Technical Field

[0001] The utility model relates to the technical field of eccentric shafts, in particular to an eccentric shaft used for installing a paper guide roller of a cigarette making machine. Background Art

[0002] Modern cigarette rolling equipment generally adopts suction forming technology to realize cigarette bundle forming in the cigarette rolling process, that is, using negative pressure suction to absorb tobacco and gather it on the suction belt, and allowing the tobacco to form a tobacco bundle through the mechanical constraint between the suction belt and the conveying channel during the forward conveying process. The tobacco bundle then enters the rolling and forming production process, which is mainly driven by the friction of the cloth belt to drive the coil paper (cigarette paper) forward to complete the wrapping and forming action of the coil paper on the tobacco bundle, and the gluing device applies glue at the overlapping position of the cigarette rod to ensure that the tobacco bundle is reliably rolled and wrapped after forming and wrapping, and does not loosen and spread.

In this patent, it is proposed that "it includes an eccentric shaft mounting part, a fixed connecting block, an eccentric shaft part, a paper guide roller mounting shaft part, an elastic cylindrical pin and an eccentric adjustment hole. A positioning groove is provided in the middle part of the shaft body of the eccentric shaft mounting part. The eccentric shaft mounting part is fixed to the frame through the circumferential matching connection of the positioning groove and the fastening screw. One end of the eccentric shaft mounting part is fixedly matched in the machine mounting hole, and the other end is connected to the fixed connecting block.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 In this embodiment, an eccentric shaft for mounting a paper guide roller of a cigarette making machine comprises a mounting seat 1, and an adjusting and disassembling mechanism is arranged on one side of the mounting seat 1.

[0024] In embodiment 1, the adjusting and disassembling mechanism includes a connecting rod 2 fixedly installed on the left side of the mounting seat 1, a mounting plate 3 is fixedly installed on the left side of the connecting rod 2, a fixed disk 4 is movably connected to the left side of the mounting plate 3, mounting boxes 5 are fixedly installed on the top and bottom of the mounting plate 3, and a fixed shaft 6 is fixedly installed inside the mounting box 5.

[0025] Among them, a return spring 7 is sleeved on the outer side of the fixed shaft 6, and a movable block 8 slidably connected to the fixed shaft 6 is fixedly installed on one side of the return spring 7. A through groove is opened on the left side of the installation box 5, and the movable block 8 is slidably connected to the fixed shaft 6 through the through groove, which helps the movable block 8 to slide and move. A movable groove is opened inside the movable block 8, and the movable block 8 is slidably connected to the fixed shaft 6 through the movable groove, which facilitates the movable block 8 to move on the outer side of the fixed shaft 6.

[0026] In this embodiment, a limit block 9 slidably connected to the installation box 5 is fixedly installed on one side of the movable block 8. A limit groove is opened on the right side of the installation box 5. The limit block 9 is slidably connected to the installation box 5 through the limit groove, which helps the limit block 9 to limit the movable block 8.

[0027] In the second embodiment, a limiting assembly is provided on one side of the movable block 8, a fixed block 10 is fixedly installed on one side of the movable block 8, a limiting pin 11 which is plugged into the fixed disk 4 is fixedly installed on one side of the fixed block 10, slots are provided on the top and bottom of the fixed disk 4, and the limiting pin 11 is plugged into the fixed disk 4 through the slots, which helps the limiting pin 11 to plug, fix and detach the fixed disk 4.

[0028] Among them, a pull ring 12 is fixedly installed on one side of the fixed block 10, and a circular groove is opened inside the pull ring 12 to facilitate pulling the pull ring 12 to move, and a paper guide roller mounting shaft 13 is fixedly installed on one side of the fixed plate 4, and an elastic cylindrical pin 14 is fixedly installed on one side of the paper guide roller mounting shaft 13. The number of the elastic cylindrical pins 14 is several, and the elastic cylindrical pins 14 are evenly arranged on one side of the paper guide roller mounting shaft 13.

[0029] It should be noted that the eccentric shaft for installing the paper guide roller of the cigarette making machine can drive the movable block 8 and the limit block 9 to move smoothly through the adjustment and disassembly mechanism, using the pull ring 12 and the fixed block 10, and conveniently drive the limit pin 11 to move telescopically. When the limit pin 11 is inserted into the interior of the fixed disk 4, the mounting plate 3 and the fixed disk 4 can be limited and fixed. When the limit pin 11 is separated from the interior of the fixed disk 4, the fixed disk 4 can be disassembled, and the paper guide roller mounting shaft 13 can be quickly disassembled and installed, thereby increasing the flexibility of the device.

[0030] The working principle of the above embodiment is:

[0031] The eccentric shaft for installing the paper guide roller of the cigarette making machine can first pull the pull ring 12 when in use, and the pull ring 12 drives the fixed block 10 to move, thereby driving the limit pin 11 to move, so that the limit pin 11 shrinks, and at the same time the fixed block 10 also drives the movable block 8 and the limit block 9 to move smoothly, the movable block 8 slides on the outside of the fixed shaft 6 and compresses the reset spring 7, and then the fixed plate 4 can be fitted and buckled on one side of the mounting plate 3, so that the slots at the top and bottom of the fixed plate 4 correspond to the limit pin 11, and at this time Loosen the pull ring 12, and the reset spring 7 starts to reset automatically. The reset spring 7 drives the movable block 8, the fixed block 10 and the limit pin 11 to reset together until the limit pin 11 is inserted into the interior of the fixed disk 4, thereby limiting and fixing the mounting plate 3 and the fixed disk 4. Similarly, pulling the pull ring 12 drives the limit pin 11 to disengage from the interior of the fixed disk 4, so that the mounting plate 3 and the fixed disk 4 can be disassembled, which helps to quickly disassemble and install the paper guide roller mounting shaft 13, greatly improving the flexibility and practicality of the device.
