[0003] The Chinese utility model patent with the publication number "CN218650253U" discloses a group of tobacco grinders with a vibrating cigarette rolling function. The tobacco grinder includes a fixed grinding disc and a movable grinding disc, and is provided with a lower column and an upper column, as well as a handle and a cigarette outlet. A conical collection cover is arranged in the collection box, an output hole is arranged in the center, and a cigarette rolling mechanism is arranged on the lower side. The cigarette rolling mechanism includes a cigarette rolling sleeve, a protective shell and a tamping device. A partition component is arranged on the collection box, including a partition disc, a first hole, a movable plate, a driving hole and a driving block. The tamping device includes a tamping shell, a tamping motor, a tamping cam, a tamping column, a tamping battery and a tamping switch. The charging port is connected to the tamping battery, and the tamping battery is a rechargeable battery. A positioning ring and a positioning hole are arranged in the tamping shell, and the tamping column is located in the positioning hole. A spring is arranged between the abutting ring and the tamping shell. The function of this tobacco grinder is that after the tobacco shreds fall into the cigarette paper, the tamping device operates to drive the cigarette rolling sleeve to quickly lift and lower. The lifting and lowering of the cigarette rolling sleeve further tamp the tobacco shreds inside the cigarette paper. After tamping is completed, the tamping device is turned off, and then the cigarette rolling mechanism is separated from the collection cover, and the cigarette can be taken off.

[0004] However, the above tobacco grinder has the following defects:

[0005] Firstly, during the cigarette rolling process of this tobacco grinder, it is necessary to continuously vibrate the cigarette rolling sleeve to load the tobacco shreds into the cigarette rolling sleeve. Although the built-in vibration function helps to compact the tobacco shreds, it will also generate additional noise and vibration during use. This not only causes discomfort to the user's touch, but also leads to the displacement or loosening of various internal components of the tobacco grinder, increasing the risk of failure. Therefore, this tobacco grinder is extremely easy to damage and not durable.

[0006] Secondly, the cigarette rolling mechanism and the tamping device for "cigarette rolling" in this tobacco grinder are sequentially distributed vertically below the grinding disc, resulting in a relatively large overall volume of the tobacco grinder and inconvenient to carry. Summary of the Utility Model

[0007] The technical problem to be solved by the utility model is to provide a tobacco grinder for spiral feeding and cigarette rolling aiming at the deficiencies of the above-mentioned prior art. On the basis of realizing tobacco grinding, it can also carry out cigarette rolling, with convenient operation. And during the cigarette rolling process, there is no need for vibrating feeding, reducing noise and vibration. The internal components of the tobacco grinder are not easy to be displaced or loosened, not easy to fail, small and light, and convenient to carry.

By adding the slider 34, the chute 35, and the spring installation hole 36, the connection stability between the paper pressing buckle 32 and the spring 33 is improved, preventing the paper pressing buckle 32 from separating from the spring 33 during the up and down movement.

[0049] The tobacco bin rack 1 includes an inner ring rack 37 and an outer ring rack 38 sleeved on the outer periphery of the inner ring rack 37. The tobacco bins 2 are distributed inside the inner ring rack 37. Two inclined planes 29 are oppositely distributed below the inner ring rack 37. The material receiving pipe 27 is distributed in the middle of the outer ring rack 38. A gear installation groove 39 is provided between the outer ring rack 38 and the inner ring rack 37. The gear installation groove 39 is distributed at one end of the material receiving pipe 27 away from the discharge port 18. A first connection block 40 is provided on the inner ring rack 37, and a second connection block 41 is provided on the outer ring rack 38 corresponding to the first connection block 40. The first connection block 40 and the second connection block 41 are detachably connected by screws. Designing the tobacco bin rack 1 as a split outer ring rack 38 and inner ring rack 37 facilitates the installation of the feeding rod 16 and the gear 23, and also facilitates the cleaning of the inside of the tobacco bin rack 1 to avoid blockage.

[0050] Working principle:

[0051] Manually rotate the movable grinding disc 6. The movable grinding disc 6 will rotate relative to the fixed grinding disc 5 under the rotational cooperation relationship between the rotating shaft 7 and the connecting hole 8. In this way, the upper cutting knife 12 moves relative to the lower cutting knife 11 to form a shearing relationship, completing the grinding and crushing of the tobacco material and finishing the tobacco grinding.

[0052] The crushed tobacco material falls into the tobacco bin 2 through the tobacco outlet holes 10 on the fixed grinding disc 5, and then gradually slides into the cigarette channel 28 under the guidance of the two inclined planes 29.

[0053] Lift the paper pressing buckle 32, and the cigarette paper tube can be inserted onto the paper rolling tube 31. When the paper pressing buckle 32 is released, the paper pressing buckle 32 resets under the action of the spring 33 and presses on the cigarette paper tube, and the cigarette paper tube can be stably inserted onto the paper rolling tube 31.

[0054] Rotate the lower cover 21, thereby driving the circular gear bar 22 to rotate. The circular gear bar 22 can drive the gear 23 to rotate. Also, since one end of the feeding rod 16 is hinged to the tobacco bin rack 1, the rotational force of the circular gear bar 22 will be converted into the rotation of the feeding rod 16. Also, due to the blades 19 spirally wound around the outer periphery of the feeding rod 16, the shredded tobacco will be extruded and transported to the discharge port 18 and gradually enter the paper rolling tube 31 to complete cigarette making.

[0055] In summary, it can be seen that the tobacco grinder designed in this embodiment can not only grind tobacco but also make cigarettes on the basis of grinding tobacco. The operation is convenient, and during the cigarette making process, there is no need for vibrating feeding, reducing noise and vibration, strengthening the stability of the overall structure of the tobacco grinder, and the internal components of the tobacco grinder are not easily displaced or loosened and are not prone to failure. Further, the spiral feeding design of the "feeding rod 16 and the blades 19" enables the shredded tobacco to be transported more smoothly to the discharge port 18 for cigarette making. Further, the feeding rod 16 is arranged at the lower part of the tobacco bin rack 1 and is arranged horizontally, making the tobacco grinder have a smaller size, being small and light, and convenient to carry.
