Description

Technical Field

[0001] This application relates to the field of cigarette machine technology, and in particular to a device for uniformly distributing tobacco shreds in a cigarette machine. Background Technology

[0002] In the tobacco manufacturing industry, cigarette making equipment, as the core equipment for processing tobacco into finished cigarettes, directly determines the quality and production efficiency of cigarette products. Currently, among the various technical solutions for cigarette making equipment, mechanical conveying still accounts for a certain proportion in some devices. This traditional mechanical conveying mode mainly uses mechanical force to move the tobacco inside the cigarette making machine.

[0003] However, during the tobacco conveying process, the mechanical conveying device, due to the relatively fixed movement trajectory and force of its mechanical components, finds it difficult to dynamically adjust according to the real-time state of the tobacco. This makes it prone to clumping or piling up of the tobacco as it flows inside the cigarette rolling machine. In some localized areas, the tobacco may form large clumps due to excessive aggregation, while in other areas, the tobacco may be sparse or even missing. This uneven distribution of tobacco not only affects the quality of the final cigarettes but can also cause problems such as jamming and clogging in the cigarette rolling machine. Summary of the Invention

[0004] The purpose of this application is to provide a device for uniformly distributing tobacco shreds in a cigarette rolling machine, which solves the problem that tobacco shreds in a cigarette rolling machine are prone to clumping or piling up in the prior art.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0006] This application provides a device for uniformly distributing tobacco shreds in a cigarette rolling machine, comprising:

[0007] A storage box, wherein a conveying pipe is installed on one side wall of the storage box;

[0008] The uniform component includes a first rotating shaft disposed inside the storage box, one end of the first rotating shaft passing through the side wall of the storage box, and a crushing wheel disposed on one side of the first rotating shaft inside the storage box.

[0009] The conveying assembly includes a second rotating shaft passing through the side wall of the storage tank. The second rotating shaft is connected to a threaded pipe on one side inside the storage tank, and one end of the threaded pipe is located inside the conveying pipe.

[0010] A drive assembly for driving the first rotating shaft and the second rotating shaft to rotate.

[0011] In this design, a storage box is used for temporary storage of tobacco shreds to be processed. A conveying pipe is installed on one side wall of the storage box to output the processed tobacco shreds to the subsequent cigarette forming process. The tobacco shreds in the storage box can be transferred to the conveying pipe via a conveying assembly and agitated by a homogenizing assembly. In use, a drive assembly rotates a first rotating shaft and a second rotating shaft. The rotation of the first rotating shaft drives a crushing wheel to rotate, which agitates the tobacco shreds, ensuring uniform distribution. The tobacco shreds agitated by the crushing wheel enter the threaded tube under the influence of gravity and the crushing wheel's agitation. As the second rotating shaft rotates, it is gradually conveyed to the conveying pipe, thus delivering the tobacco shreds.

[0012] This solution utilizes a uniform agitator to loosen the tobacco shreds, effectively preventing clumping and buildup. This promotes the flow of tobacco within the storage tank, resulting in a more even distribution. The threaded tube conveyor system ensures the tobacco is evenly transported into the delivery pipe, reducing equipment jams and malfunctions caused by clogging and improving the operational stability and production efficiency of the cigarette-making machine.

[0013] Optionally, the storage tank is provided with a triangular frustum having an inclined surface that defines a crushing groove suitable for accommodating the crushing wheel.

[0014] This design incorporates a triangular truncated pyramid within the storage box. The pyramid has an inclined surface, allowing the tobacco shreds to move along this inclined surface to the crushing and conveying area under the influence of gravity.

[0015] Optionally, the drive assembly includes: a first gear axially disposed on the first rotating shaft, a second gear axially disposed on the second rotating shaft and meshing with the first gear, and a crank handle disposed on the first rotating shaft or the second rotating shaft, wherein the first gear, the second gear and the crank handle are located outside the storage box.

[0016] This solution achieves synchronous rotation of the first and second shafts by turning a crank handle. In use, the operator can manually crank the handle to rotate the first and second shafts synchronously, thus synchronizing the conveying and agitation of the tobacco.

[0017] Optionally, a protective cover is provided on one side of the storage box, and the first gear and the second gear are located inside the protective cover.

[0018] Optionally, the storage box is provided with a feeding cylinder at the top, the feeding cylinder is connected to the storage box through a discharge pipe, and the feeding cylinder is provided with a feed pipe.

[0019] Optionally, the feeding cylinder is provided with a drying component, which includes a fan disposed in the feeding cylinder and an agitator for agitating the tobacco.

[0020] Optionally, the agitator includes a third rotating shaft disposed inside the feeding cylinder, the third rotating shaft being provided with a plurality of agitating rods, and one end of the third rotating shaft passing through the side wall of the feeding cylinder and connected to an agitating motor.

[0021] To prevent excessive moisture in the tobacco, which can lead to clumping, sticking, and even mold, this solution incorporates a drying assembly within the feeding hopper. This assembly includes a fan and an agitator to stir the tobacco. The fan accelerates airflow within the hopper, speeding up moisture evaporation and achieving a drying effect. Furthermore, to ensure sufficient contact between the tobacco and air, further accelerating moisture evaporation, the agitator further stirs the tobacco. This agitator comprises a third rotating shaft, an agitator rod, and an agitator motor. The motor rotates the third rotating shaft, which in turn drives the agitator rod to stir the tobacco, ensuring even drying. The agitation by the agitator rod also directs the tobacco through the discharge pipe into the storage tank, preventing accumulation within the feeding hopper.

[0022] Optionally, it also includes a cigarette assembly, which includes a fixing ring coaxially arranged with the delivery pipe, a cigarette tube passing through the fixing ring, and one end of the cigarette tube being sleeved on the outer wall of the delivery pipe.

[0023] Optionally, a collection box is provided on one side of the conveying pipe, and the storage box has a port facing the inhalation pipe inside the collection box. In this design, the cigarette tube is inserted from the fixing ring side, with one end sleeved on the outer wall of the conveying pipe. Tobacco can enter the cigarette tube through the conveying pipe to realize the cigarette rolling operation. During the cigarette rolling process, tobacco overflowing from one end of the cigarette tube will fall into the collection box and be collected into the storage box through the inhalation pipe.

[0024] Compared with existing technologies, the beneficial effects achieved by this application are as follows: Through a uniform component, the tobacco shreds in the storage box can be agitated to a loose state, effectively preventing the tobacco shreds from clumping and piling up. This promotes the flow of tobacco shreds within the storage box, resulting in a more uniform distribution. Furthermore, the threaded tube conveying system ensures that the tobacco shreds are evenly transported into the conveying pipe, reducing equipment jams and malfunctions caused by tobacco shred blockages, and improving the operational stability and production efficiency of the cigarette-making machine.

Detailed Implementation

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0032] Example 1

[0033] This embodiment describes a device for uniformly distributing tobacco shreds in a cigarette rolling machine, referencing... Figures 1 to 3The tobacco shred uniform distribution device for the cigarette machine in this embodiment includes a storage box 1, which is used to temporarily store tobacco shreds to be processed. A conveying pipe 11 is provided through one side wall of the storage box 1 for outputting the processed tobacco shreds to the subsequent cigarette forming process. The tobacco shreds in the storage box 1 are transferred to the conveying pipe 11 through the conveying assembly 3 and agitated by the uniform distribution assembly 2. The uniform distribution assembly 2 includes a first rotating shaft 21 disposed inside the storage box 1, one end of which passes through the side wall of the storage box 1. A crushing wheel 22 is disposed on the side of the first rotating shaft 21 inside the storage box 1. The rotation of the first rotating shaft 21 drives the crushing wheel 22 to rotate, and the rotation of the crushing wheel 22 agitates the tobacco shreds to ensure uniform distribution. The conveying assembly 3 includes a second rotating shaft 31 that passes through the side wall of the storage box 1. A threaded pipe 32 is connected to the side of the second rotating shaft 31 inside the storage box 1, and one end of the threaded pipe 32 is located inside the conveying pipe 11. The tobacco shreds, agitated by the crushing wheel 22, enter the threaded tube 32 under the influence of gravity and the action of the crushing wheel 22. As the second rotating shaft 31 rotates, the threaded tube 32 rotates and is gradually transported to the conveying tube 11, thus delivering the tobacco shreds.

[0034] In this embodiment, the uniformizing component 2 agitates the tobacco shreds to a loose state, effectively preventing them from clumping and piling up. This promotes the flow of tobacco shreds within the storage box 1, resulting in a more uniform distribution. Through the threaded tube 32, the tobacco shreds are evenly conveyed into the conveying pipe 11, reducing equipment jams and malfunctions caused by tobacco blockage and improving the operational stability and production efficiency of the cigarette rolling machine.

[0035] In this embodiment, the first rotating shaft 21 and the second rotating shaft 31 are rotated by a drive assembly 4. Specifically, the drive assembly 4 includes: a first gear 41 axially mounted on the first rotating shaft 21, a second gear 42 axially mounted on the second rotating shaft 31 and meshing with the first gear 41, and a crank 43 mounted on either the first rotating shaft 21 or the second rotating shaft 31. The first gear 41, the second gear 42, and the crank 43 are located outside the storage box 1. A protective cover 5 is provided on one side of the storage box 1, and the first gear 41 and the second gear 42 are located inside the protective cover 5. In use, the operator can manually crank the crank 43 to drive the first rotating shaft 21 and the second rotating shaft 31 to rotate synchronously, so that the tobacco conveying and stirring are carried out simultaneously.

[0036] In this embodiment, a triangular frustum 12 is provided inside the storage box 1. The triangular frustum 12 has an inclined surface, which defines a crushing groove 121 to accommodate the crushing wheel 22. The tobacco can move along the inclined surface to the crushing and conveying area under the action of gravity.

[0037] Example 2:

[0038] Based on the same inventive concept as Embodiment 1, refer to Figure 2 and Figure 4In this embodiment, a feeding cylinder 6 is provided at the top of the storage box 1. The feeding cylinder 6 is connected to the storage box 1 through a discharge pipe 61, and a feeding pipe 62 is provided on the feeding cylinder 6. The tobacco enters the feeding cylinder 6 through the feeding pipe 62 and enters the storage box 1 through the discharge pipe 61.

[0039] To prevent excessive moisture in the tobacco from causing it to stick together, clump, or even mold, a drying component 7 is installed inside the feeding cylinder 6. The drying component 7 includes a fan 71 located within the feeding cylinder 6. The fan 71 accelerates airflow within the feeding cylinder 6, thereby speeding up the evaporation of moisture from the tobacco and achieving a drying effect.

[0040] To ensure that the tobacco shreds in the feeding cylinder 6 can fully contact the air, thereby accelerating the evaporation of moisture from the tobacco shreds, this embodiment also uses an agitator 72 to agitate the tobacco shreds. Specifically, the agitator 72 includes a third rotating shaft 721 disposed within the feeding cylinder 6, with multiple agitating rods 722 mounted on the third rotating shaft 721. One end of the third rotating shaft 721 passes through the side wall of the feeding cylinder 6 and is connected to an agitator motor 723. The rotation of the agitator motor 723 drives the third rotating shaft 721 to rotate, which in turn drives the agitator rods 722 to agitate the tobacco shreds, thereby ensuring that the tobacco shreds in the feeding cylinder 6 are dried evenly. The agitation by the agitator rods 722 also allows the tobacco shreds to enter the storage tank 1 through the discharge pipe 61, preventing the tobacco shreds from accumulating in the feeding cylinder 6.

[0041] Example 3:

[0042] Based on the same inventive concept as Embodiment 1, refer to Figure 1 and Figure 2 The cigarette machine tobacco uniform distribution device in this embodiment also includes a cigarette assembly 8. The cigarette assembly 8 includes a fixing ring 81 coaxially arranged with the conveying pipe 11. A cigarette tube 82 is inserted inside the fixing ring 81, and one end of the cigarette tube 82 is sleeved on the outer wall of the conveying pipe 11.

[0043] During the cigarette rolling process, the cigarette tube 82 is inserted from one side of the fixing ring 81, with one end sleeved on the outer wall of the conveying pipe 11. Tobacco shreds can be filled into the cigarette tube 82 from the conveying pipe 11. After filling, the cigarette tube 82 can be removed to complete the cigarette rolling process.

[0044] Furthermore, a collection box 9 is provided on one side of the storage box 1 located on the conveying pipe 11. The storage box 1 has a port facing the suction pipe 13 inside the collection box 9, and the suction pipe 13 is connected to a negative pressure pump. During the cigarette rolling process, the tobacco overflowing from one end of the cigarette tube 82 will fall into the collection box 9 and be recycled back into the storage box 1 through the suction pipe 13.

[0045] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
