Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cigarette processing equipment, specifically relating to a pre-rolling mechanical assembly for cigarette paper in a cigarette machine. Background Technology
[0002] In the production and processing of cigarettes, cigarette paper is an essential material. Before entering the formal production process, cigarette paper usually needs to be pre-rolled. Currently, existing cigarette paper pre-rolling devices are usually simple in structure and lack tension during the pre-rolling process, which can easily lead to the cigarette paper becoming loose or falling off midway. In addition, the diameter of the pre-rolled cigarette paper cannot be adjusted, resulting in low production efficiency. Utility Model Content
[0003] To address the aforementioned problems, this utility model aims to provide a pre-rolling mechanical assembly for cigarette paper in cigarette making machines. This assembly enables the cigarette paper to be tightly wound and formed, resulting in high-quality, uniformly sized pre-rolled cigarette paper. Furthermore, the diameter of the pre-rolled cigarette paper can be adjusted to process cigarette paper for various specifications of cigarettes.
[0004] The technical problem solved by this utility model can be achieved by the following technical solution: A pre-rolling mechanical assembly for cigarette paper in a cigarette machine, comprising a drive unit, a transmission assembly, a paper rolling assembly, and cigarette paper. The drive unit is connected to a drive gear. The transmission assembly includes a transmission gear and a transmission shaft. The drive gear and the transmission gear are meshed and connected. The transmission shaft passes through and connects to the transmission gear, so that the drive unit drives the transmission shaft to rotate. The paper rolling assembly includes several rollers and paper rolling components. The surface of the paper rolling component abuts against each roller. One end of the paper rolling component is detachably connected to the end of the transmission shaft. The cigarette paper is connected to the paper rolling component and is pre-rolled and formed by the rotation of the paper rolling component.
[0005] It also includes a fixing part, with both ends of the roller component being fixedly connected to the fixing part.
[0006] The surface of the cigarette paper roll is provided with a groove, and one end of the cigarette paper is matched and connected to the groove.
[0007] The drive shaft is equipped with a tension groove, which allows the drive shaft to contract or expand when connected to paper rolls of different diameters.
[0008] The paper rolls are made of zinc rods.
[0009] It also includes a counting unit, which is used to count the number of rotations of the drive shaft.
[0010] Compared with the prior art, this utility model has the following advantages: This utility model can tightly wind and form cigarette paper, and the pre-wound cigarette paper has high quality and uniform specifications. Moreover, the diameter of the pre-wound cigarette paper can be adjusted to process cigarette paper required for various specifications of cigarettes. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0014] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0015] Combined with appendix Figures 1 to 4 As shown, this embodiment discloses a pre-rolling mechanical assembly for cigarette paper in a cigarette rolling machine, including a drive unit 1, a transmission assembly 2, a paper rolling assembly 3, and cigarette paper 5. The drive unit 1 is connected to a drive gear 11. Preferably, the drive unit 1 is a motor, which can drive the drive gear 11 to rotate. The transmission assembly 2 includes a transmission gear 21 and a transmission shaft 22. The drive gear 11 and the transmission gear 21 are meshed together. When the drive gear 11 rotates, it can drive the transmission gear 21 to rotate in coordination. The transmission shaft 22 passes through and connects to the transmission gear 21, so that the drive unit 1 drives the transmission shaft 22 to rotate. The paper rolling assembly 3 includes several rollers 31 and paper rolling parts 32. Preferably, in this embodiment, the number of rollers 31 is three, with one roller 31 on each of the upper left and right sides of the paper rolling part 32 and one roller 31 on the lower part of the paper rolling part 32. The surface of the paper rolling part 32 abuts against each roller 31, and the rollers 31 are in contact with the paper rolling part. A certain pressure is applied to the surface of 32 to prevent the cigarette paper 5 from loosening or detaching during the pre-rolling process. One end of the paper rolling component 32 is detachably connected to the end of the drive shaft 22, so that when the drive shaft 22 rotates, it can drive the paper rolling component 32 to rotate in coordination. The cigarette paper 5 is connected to the paper rolling component 32 and is pre-rolled and formed by the rotation of the paper rolling component 32.
[0016] In conjunction with the above, it also includes a fixing part 4, with both ends of the roller 31 fixedly connected to the fixing part 4, so that the position and height of the roller 31 remain fixed, thereby improving the stability of the structure of this utility model.
[0017] In conjunction with the above, the surface of the paper roll 32 is provided with a groove 321, and one end of the cigarette paper 5 is matched and connected with the groove 321, so that one end of the cigarette paper 5 is firmly fixed by the groove 321. When the paper roll 32 rotates, it can provide a certain tension force, so that the cigarette paper 5 adheres tightly to the surface of the paper roll 32 during the pre-rolling process, further preventing the cigarette paper 5 from loosening or detaching during the pre-rolling process.
[0018] In conjunction with the above installation structure, a tension groove 221 is provided on the drive shaft 22, so that the drive shaft 22 can shrink or expand when connected to paper rolls 32 of different diameters.
[0019] In combination with the above, preferably, in this embodiment, the paper roll 32 is made of zinc rod. In other embodiments, other common materials or structures may also be used.
[0020] In conjunction with the above-described installation structure, a counting unit 6 is also included. The counting unit 6 is used to count the number of rotations of the drive shaft 22 to prevent the cigarette paper 5 from being pre-wound too many times, so that the cigarette paper 5 produced is of uniform specifications. Preferably, in this embodiment, the counting unit 6 is located above the connection between the drive shaft 22 and the paper rolling component 32.
[0021] This invention enables cigarette paper to be tightly wound and formed, resulting in high-quality, uniformly sized cigarette paper after pre-winding. Furthermore, the diameter of the pre-wound cigarette paper can be adjusted to process cigarette paper for various specifications of cigarettes.
[0022] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
