Description

Technical Field

[0001] This utility model relates to the field of tobacco processing, and in particular to a drum adsorption type tobacco leaf dispersion device. Background Technology

[0002] In the tobacco processing industry, the dispersion of tobacco leaves is a crucial step in cigarette production. Traditional methods of tobacco leaf dispersion largely rely on manual operation, which is not only inefficient but also makes it difficult to ensure uniformity and consistency in dispersion. Furthermore, piles of tobacco leaves tend to stick together during transport, causing difficulties in subsequent processing. Utility Model Content

[0003] The purpose of this invention is to provide a drum adsorption type tobacco leaf dispersion device to solve the problem that the existing technology lacks a way to disperse stacked tobacco leaves and relies too much on manual labor.

[0004] The technical solution of this utility model is: a drum adsorption type tobacco leaf dispersion device, including a base, a conveying mechanism laid on the base, a drum mechanism corresponding to the end of the conveying mechanism in the running direction, the drum mechanism including a drum that can rotate around its own axis, a negative pressure device is provided inside the drum, and an adsorption hole is opened on the outer surface of the drum.

[0005] Having a first position and a second position allows the roller to adsorb tobacco leaves at the first position and detach them at the second position.

[0006] Preferably, there are multiple rollers arranged side by side in a horizontal direction and fixed to the base by a fixing frame; the multiple rollers rotate in the same direction in the working state.

[0007] Preferably, the conveying mechanism includes a conveyor wheel, the two ends of which are rotatably connected to the base, and a conveyor belt is fitted on the conveyor wheel. The conveyor wheel rotates around its own axis, driving the conveyor belt to run.

[0008] Preferably, a guide rod is provided, which is fixed to the base in the horizontal direction and abuts against the conveyor belt. The guide rod is arranged in three groups on the base, and the three groups of guide rods abut against the upper and lower surfaces of the conveyor belt respectively, so that a raised, dispersed slope is formed in the middle of the conveying mechanism.

[0009] Preferably, the conveyor belt is fixed with partition plates at preset intervals, and the area between adjacent partition plates forms a place for tobacco leaves.

[0010] Preferably, a feeding mechanism is provided on the base, and the feeding mechanism is located below the roller mechanism.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] This application utilizes a roller mechanism and a negative pressure device and suction holes to precisely adsorb tobacco leaves in specific positions, ensuring that only one leaf is processed at a time. Furthermore, the device incorporates two parallel rotating rollers, which solves the problem of partially overlapping tobacco leaves, allowing overlapping leaves to be separated and processed individually.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0021] The present invention will be further described in detail below with reference to specific embodiments:

[0022] like Figure 1 and Figure 2 As shown, a drum 31 adsorption-type tobacco leaf dispersion device includes a base 1, on which a conveying mechanism 2 and a drum mechanism 3 are laid. The conveying mechanism 2 is used to transport tobacco leaves toward the drum mechanism 3, and the drum mechanism 3 is used to disperse the pile of tobacco leaves so that they enter the feeding mechanism 5 in the form of individual leaves.

[0023] Specifically, the conveying mechanism 2 includes conveyor wheels 21 and a conveyor belt 22. At least two sets of conveyor wheels 21 are configured, and both sets are rotatably connected to the base 1 and can rotate around their own axes during operation. The conveyor belt 22 is a ring structure, with both ends respectively fitted onto the two sets of conveyor wheels 21. The two sets of conveyor wheels 21 rotate simultaneously in a counter-clockwise or clockwise direction, thereby driving the conveyor belt 22 and ensuring that its upper surface faces the roller mechanism 3.

[0024] In a preferred embodiment of this application, a partition plate 23 is vertically fixed on the outer surface of the conveyor belt 22. Multiple partition plates 23 are set on the outer surface of the conveyor belt 22 at a preset interval. The length direction of any partition plate 23 is perpendicular to the length direction of the conveyor belt 22, so that an area for placing tobacco leaves is formed between adjacent partition plates 23.

[0025] The roller mechanism 3 includes a roller 31 mounted on the base 1 via a fixing frame 33. The roller 31 can rotate around its own axis during operation, and its rotation direction is the same as that of the conveyor wheel 21. A negative pressure device is installed inside the roller 31, and multiple adsorption holes 32 are formed on the outer surface of the roller 31. The negative pressure device generates negative pressure and adsorbs the tobacco leaves in the first position through the adsorption holes 32.

[0026] The first position is set at the end of the conveyor belt 22 near the roller mechanism 3. At this position, the negative pressure generated by the negative pressure device will adsorb one of the piled tobacco leaves onto the roller 31. This tobacco leaf will also block part of the adsorption hole 32, so that the corresponding area of ​​the roller 31 will no longer generate negative pressure to the outside, thereby achieving the effect of adsorbing only one tobacco leaf at the same position on the roller 31.

[0027] When the tobacco leaves on the drum 31 rotate to the lower position, there is a second position, which allows the tobacco leaves to overcome the suction force of the drum 31 and separate from the drum 31 under the combined action of their own gravity and the centrifugal force, and fall into the feeding mechanism 5 below the drum mechanism 3.

[0028] In practical applications, there is a situation where a portion of a tobacco leaf is adsorbed by the negative pressure device of the roller 31, while another portion overlaps with the previously adsorbed tobacco leaf, thus affecting the dispersion effect of the tobacco leaf. Therefore, in the preferred embodiment of this application, the rollers 31 in the roller mechanism 3 are configured in pairs, namely the first roller 31a and the second roller 31b, which are arranged side by side and rotate in the same direction.

[0029] When a tobacco leaf is partially adsorbed while another part covers another tobacco leaf, the surface of the tobacco leaf that is away from the first roller 31a will be subject to a relatively greater adsorption force from the second roller 31b. Therefore, the tobacco leaf will detach from the first roller 31a and be adsorbed onto the second roller 31b, where it will be dematerialized.

[0030] In a preferred embodiment of this application, in order to further improve the dispersion effect of the tobacco leaves, a preliminary dispersion is performed before the tobacco leaves enter the drum mechanism 3. The preliminary dispersion is achieved in the following manner:

[0031] like Figure 3 As shown, guide rods 4 are arranged horizontally on the base 1, and there are three sets of guide rods 4. The two sets of guide rods 4 located at the edges abut against the upper surface of the conveyor belt 22, while the guide rods 4 located in the middle are raised and abut against the lower surface of the conveyor belt 22, creating a raised dispersing slope in the middle of the conveying mechanism 2. This allows the tobacco leaves to move uphill and downhill on the conveying mechanism 2. The piled tobacco leaves can be naturally dispersed by the uphill and downhill movements, thus achieving initial dispersion of the tobacco leaves before entering the drum mechanism 3.

[0032] During work:

[0033] The pile of tobacco leaves is fed from the end of the conveyor 2 away from the roller mechanism 3, and moves toward the roller mechanism 3 under the drive of the conveyor 2. When passing through the dispersing slope in the middle of the conveyor 2, the pile of tobacco leaves is initially dispersed into several smaller piles of tobacco leaves.

[0034] When a smaller pile of tobacco leaves enters the first position at the end of the conveying mechanism 2, the negative pressure device inside the roller 31 adsorbs the tobacco leaves onto the first roller 31a and drives the tobacco leaves into the second position for discharge. If there are overlapping tobacco leaves during this process, the second roller 31b can adsorb the overlapping tobacco leaves in the same way and discharge them individually.

[0035] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore, all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
