Description

Technical Field

[0001] The invention relates to the field of tobacco leaf production, and in particular to a tobacco leaf slicing device and method. Background Art

[0002] The production process of modern cigarette products generally goes through the production process of tobacco leaf initial baking, leaf beating and re-baking, tobacco leaf fermentation, cigarette formula, cigarette silk making, cigarette stick making, cigarette packaging and other production processes. Among them, tobacco leaf initial baking is the first link to turn the cultivated tobacco leaves into cigarette raw materials. It is the process of farmers placing the fresh tobacco leaves harvested from the fields in the baking room for baking and curing to make them into "raw tobacco" raw materials for cigarettes. After baking, the tobacco leaves have undergone significant changes in the content, appearance and microstructure. The color of the tobacco leaves changes from yellow-green to yellow, and the water content of the tobacco leaves changes from the expanded state of 80-90% to withering, drying and even charring. After the initial baking of tobacco leaves, the withered and dried tobacco leaves are usually bundled together for subsequent processing. The tobacco leaves bundled together need to be pre-treated before production, such as separating the stacked or gathered tobacco leaves separately for subsequent production processing. However, the traditional tobacco leaf separation process is achieved manually. On the one hand, the labor efficiency is low, which reduces production efficiency, and on the other hand, it increases labor costs. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical solutions of the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0031] The tobacco leaf separation device disclosed in the present invention can separate tobacco leaves that are gathered or stacked together, and transport individual tobacco leaves to the next process one by one, thereby improving production efficiency.

[0032] Figure 1 and Figure 2 As shown, a tobacco leaf segmenting device disclosed in the present invention comprises a tobacco leaf queuing mechanism 10, a tobacco leaf dislocation mechanism 20, a tobacco leaf delivery mechanism 30, a tobacco leaf input mechanism 40 and a tobacco leaf output mechanism 50, wherein the tobacco leaf queuing mechanism 10, the tobacco leaf dislocation mechanism 20 and the tobacco leaf delivery mechanism 30 are arranged between the tobacco leaf input mechanism 40 and the tobacco leaf output mechanism 50, and the tobacco leaf queuing mechanism 10 is arranged between the tobacco leaf input mechanism 40 and the tobacco leaf dislocation mechanism 20, the tobacco leaf dislocation mechanism 20 is arranged between the tobacco leaf queuing mechanism 10 and the tobacco leaf output mechanism 50, and the tobacco leaf delivery mechanism 30 is arranged between the tobacco leaf queuing mechanism 10 and the tobacco leaf output mechanism 50, and is arranged close to the tobacco leaf dislocation mechanism 20.

[0033] During implementation, the tobacco leaf input mechanism 40 separates the tobacco leaves that are gathered or stacked together and conveys them to the tobacco leaf queuing mechanism 10. The tobacco leaf queuing mechanism 10 further arranges the tobacco leaves in order and conveys them to the tobacco leaf dislocation mechanism 20. The tobacco leaf dislocation mechanism 20 further makes the tobacco stems of the tobacco leaves present a preset angle with the horizontal direction and conveys the tobacco leaves to the tobacco leaf conveying mechanism 30. The tobacco leaf conveying mechanism 30 moves the tobacco leaves in the tobacco leaf dislocation mechanism 20 one by one and conveys the tobacco leaves to the tobacco leaf output mechanism 50. The tobacco leaf output mechanism 50 further conveys the tobacco leaves one by one to the next process, thereby finally realizing the separation processing of the tobacco leaves.

[0034] Combination Figure 1 and Figure 2 As shown, the tobacco leaf queuing mechanism 10 is used to arrange tobacco leaves in order, and includes a driving roller group and a driven roller group. The driving roller group includes a first driving roller a and a second driving roller b arranged at intervals along a third direction Z, and the first driving roller a and the second driving roller b rotate synchronously in opposite directions, and the driven roller group includes a first driven roller c and a second driven roller d arranged at intervals along the third direction Z, and the first driven roller c and the second driven roller d also rotate synchronously in opposite directions.

[0035] Furthermore, a first conveyor belt 11 is disposed around the first active roller a and the first driven roller c, and at least two second conveyor belts 12 are disposed around the second active roller b and the second driven roller d, and the first conveyor belt 11 is located above the second conveyor belts 12 and is in the same plane as any second conveyor belt 12. At the same time, a gap (not shown) is formed between the second conveyor belt 12 and the first conveyor belt 11 that are in the same plane as the first conveyor belt 11, and the gap can be used for sorting tobacco leaves. In this embodiment, the gap can only accommodate a tobacco stem in the third direction Z, so that the tobacco leaves moving along the first direction X can be arranged in order in the gap.

[0036] During implementation, the first active roller a and the second active roller b in the active roller group rotate synchronously in opposite directions under the action of an external force (such as a rotating motor, etc.), and the first active roller a and the second active roller b drive the first conveyor belt 11 and the second conveyor belt 12 to rotate through the first driven roller c and the second driven roller d respectively, so as to convey tobacco leaves to the tobacco leaf dislocation mechanism 20. The tobacco leaf input mechanism 40 conveys the separated tobacco leaves to the gap between the first conveyor belt 11 and the second conveyor belt 12 in sequence, and the tobacco stems of the tobacco leaves are arranged in order under the support of the second conveyor belt 12. The first conveyor belt 11 and / or the second conveyor belt 12 continuously convey the orderly arranged tobacco leaves to the tobacco leaf dislocation mechanism 20 through the friction force generated between the tobacco stems of the tobacco leaves.

[0037] like Figure 2 As shown, the tobacco leaf dislocation mechanism 20 is used to make the tobacco stems of the tobacco leaves present a preset angle with the horizontal direction and transport the tobacco leaves to the tobacco leaf delivery mechanism 30, which also includes an active roller group and a driven roller group. In this embodiment, the tobacco leaf dislocation mechanism 20 and the tobacco leaf queuing mechanism 10 share the active roller group. This design method can effectively reduce costs and reduce the space occupied by parts. Of course, in other embodiments, the tobacco leaf dislocation mechanism 20 and the tobacco leaf queuing mechanism 10 may not share the active roller group, and can be set according to actual needs.

[0038] In the tobacco leaf dislocation mechanism 20, the specific structures of the active roller group and the driven roller group are detailed in the tobacco leaf queuing mechanism 10, and will not be described one by one here. In the tobacco leaf dislocation mechanism 20, a third conveyor belt 21 is arranged around the first active roller a and the first driven roller c, and a fourth conveyor belt 22 is arranged around the second active roller b and the second driven roller d. In order to achieve a preset angle between the tobacco stems and the horizontal direction, which is convenient for the movement of the tobacco leaf shifting mechanism 30, the third conveyor belt 21 and the fourth conveyor belt 22 are arranged at intervals along the second direction Y, and the third conveyor belt 21 is located above the fourth conveyor belt 22 in the third direction Y, and a gap is formed between the third conveyor belt 21 and the fourth conveyor belt 22. During implementation, the tobacco leaves entering the tobacco leaf dislocation mechanism 20 have their stems located between the third conveyor belt 21 and the fourth conveyor belt 22, and one end of the tobacco stems abuts against the third conveyor belt 21 at a higher position, and the other end abuts against the fourth conveyor belt 22 at a lower position, thereby achieving a certain angle between the tobacco stems and the horizontal direction, which is beneficial to the movement of the tobacco leaf feeding mechanism 30.

[0039] In this embodiment, the first conveyor belt 11, the second conveyor belt 12, the third conveyor belt 21 and the fourth conveyor belt 22 are preferably conveyor belts with circular cross sections.

[0040] like Figure 3 As shown, the tobacco leaf conveying mechanism 30 includes a supporting plate 31, a transfer drive mechanism and at least two material conveying roller groups 32, wherein a plurality of material conveying roller groups 32 are arranged on the supporting plate 31 at intervals along a first direction X (i.e., the direction of tobacco leaf movement) for conveying tobacco leaves; the transfer drive mechanism is connected to the supporting plate 31, and is used to drive the supporting plate 31 to reciprocate along the first direction X, thereby continuously moving the tobacco leaves toward the tobacco leaf output mechanism 50 through the material conveying roller groups 32.

[0041] Furthermore, each material-moving roller group 32 includes a first moving roller 321 and a second moving roller 322 arranged along the third direction Z, the first moving roller 321 and the second moving roller 322 rotate synchronously in opposite directions, and the first moving roller 321 and the second moving roller 322 are arranged between the third conveyor belt 21 and the fourth conveyor belt 22.

[0042] In this embodiment, each material-moving roller group 32 is connected to a corresponding driving mechanism, which can drive the first moving roller 321 and the second moving roller 322 to rotate synchronously in opposite directions. The driving mechanism is such as a rotating motor, that is, each material-moving roller group 32 can be driven individually by the corresponding driving mechanism to realize the movement of tobacco leaves.

[0043] Furthermore, taking the three material-feeding roller groups 32 (referred to as the first material-feeding roller group, the second material-feeding roller group and the third material-feeding roller group in sequence along the first direction X) arranged on the supporting plate 31 as an example, how the tobacco leaf-feeding mechanism 30 realizes the tobacco leaf-feeding is described in detail.

[0044] When the transfer drive mechanism drives the support plate 31 to move to the maximum stroke, the third conveyor belt 21 and the fourth conveyor belt 22 in the tobacco leaf dislocation mechanism 20 stop rotating, and the first paddle roller 321 and the second paddle roller 322 in the first paddle roller group start to rotate synchronously in the opposite direction to paddle a tobacco leaf clamped between the third conveyor belt 21 and the fourth conveyor belt 22, so as to separate the tobacco leaf from the other tobacco leaves and paddle the tobacco leaf between the first paddle roller group and the second paddle roller group, and the transfer drive mechanism further drives the support plate 31 to reset, and the first paddle roller group drives the tobacco leaf to move a certain distance toward the tobacco leaf output mechanism 50;

[0045] Furthermore, the transfer drive mechanism continues to drive the support plate 31 to move to the maximum stroke. At this time, the second material-moving roller group moves to the tobacco leaves, and rotates the first moving roller 321 and the second moving roller 322 therein to move the tobacco leaves between the second material-moving roller group and the third material-moving roller group. The transfer drive mechanism further drives the support plate 31 to reset, and the second material-moving roller group drives the tobacco leaves to move a certain distance again in the direction of the tobacco leaf output mechanism 50.

[0046] Furthermore, the transfer drive mechanism continues to drive the support plate 31 to move to the maximum stroke. At this time, the third material transfer roller group moves to the tobacco leaves, and rotates the first and second transfer rollers 321 and 322 therein to transfer the tobacco leaves between the third material transfer roller group and the tobacco leaf output mechanism 50. The transfer drive mechanism further drives the support plate 31 to reset, and the third material transfer roller group drives the tobacco leaves to move to the tobacco leaf output mechanism 50.

[0047] By repeating the above process, the tobacco leaves between the third conveyor belt 21 and the fourth conveyor belt 22 can be transported one by one to the tobacco leaf output mechanism 50.

[0048] like Figure 3 As shown, the transfer drive mechanism includes a swing rod 33, a rotating disk 34 and a power source 35 for driving the rotating disk 34 to rotate. Among them, one end of the swing rod 33 is pivoted to the supporting plate 31, and the other end is pivoted to the edge of the rotating disk 34. During implementation, the power source 35 drives the rotating disk 34 to rotate, and the rotating disk 34 drives the swing rod 33 to swing back and forth during the rotation process, and the swing rod 33 further drives the supporting plate 31 to move back and forth along the moving direction of the tobacco leaves. In this embodiment, the power source 35 is preferably a rotary motor.

[0049] like Figure 2As shown, the tobacco leaf input mechanism 40 includes a deceleration conveying mechanism 41 for slowly conveying tobacco leaves and an acceleration conveying mechanism 42 for accelerating and separating a plurality of gathered tobacco leaves. The acceleration conveying mechanism 42 is arranged between the deceleration conveying mechanism 41 and the tobacco leaf queuing mechanism 10. Specifically, the acceleration conveying mechanism 42 includes at least two conveying roller groups spaced apart in the first direction X, each conveying roller group includes a first conveying roller e and a second conveying roller f spaced apart in the third direction Z, and in two adjacent conveying roller groups, a fifth conveying belt 421 is arranged around the two first conveying rollers e, and a sixth conveying belt 422 is arranged around the two second conveying rollers f. The fifth conveying belt 421 and the sixth conveying belt 422 are arranged closely to generate a clamping force. During implementation, the tobacco leaves are located between the fifth conveying belt 421 and the sixth conveying belt 422, and are continuously moved under the clamping of the fifth conveying belt 421 and the sixth conveying belt 422.

[0050] The deceleration conveying mechanism 41 includes two conveying roller groups spaced apart in the direction of tobacco leaf movement, and each conveying roller group includes a first conveying roller e and a second conveying roller f spaced apart in the third direction Z. In this embodiment, the deceleration conveying mechanism 41 and the acceleration conveying mechanism 42 share a conveying roller group, and at the same time, the acceleration drive mechanism shares the driven roller group in the tobacco leaf queuing mechanism 10. This design can effectively reduce costs and reduce the space occupied by components.

[0051] Furthermore, in the deceleration conveying mechanism 41, a seventh conveyor belt 411 is disposed around the two first conveyor rollers e, and an eighth conveyor belt 412 is disposed around the two second conveyor rollers f. The seventh conveyor belt 411 and the eighth conveyor belt 412 are disposed in close contact with each other to generate a clamping force. During implementation, the tobacco leaves are located between the seventh conveyor belt 411 and the eighth conveyor belt 412, and are clamped and fixed by the seventh conveyor belt 411 and the eighth conveyor belt 412, so that the tobacco leaves can be continuously or intermittently moved to the acceleration conveying mechanism 42.

[0052] During implementation, the tobacco leaves enter the deceleration conveying mechanism 41 and slowly move to the acceleration conveying mechanism 42 in the deceleration conveying mechanism 41. When a tobacco leaf moves to the acceleration conveying mechanism 42, the acceleration conveying mechanism 42 accelerates the tobacco leaf to move to the tobacco leaf queuing mechanism 10 to keep a certain distance from the next tobacco leaf, thereby achieving separation between the tobacco leaves.

[0053] like Figure 2As shown, the tobacco leaf output mechanism 50 includes an active roller group and a driven roller group. In this embodiment, the tobacco leaf output mechanism 50 and the tobacco leaf dislocation mechanism 20 share the driven roller group. Of course, in other embodiments, the tobacco leaf output mechanism 50 may not share the driven roller group with the tobacco leaf dislocation mechanism 20, and can be set according to actual needs. Further, in the tobacco leaf dislocation mechanism 20, the first active roller a and the first driven roller c are surrounded by a ninth conveyor belt 51, and the second active roller b and the second driven roller d are surrounded by a tenth conveyor belt 52. The ninth conveyor belt 51 is located above the tenth conveyor belt 52, and the two are closely arranged to generate a clamping force. During implementation, the tobacco leaves are placed between the ninth conveyor belt 51 and the tenth conveyor belt 52, and are clamped and fixed by the ninth conveyor belt 51 and the tenth conveyor belt 52. The tobacco leaves can be moved to the outside continuously or intermittently, and no external force is required for clamping, and there is no noise during the transmission process.

[0054] The present invention realizes the initial separation of the stacked or gathered tobacco leaves through the tobacco leaf input mechanism, and further transports the tobacco leaves one by one to the tobacco leaf output mechanism through the tobacco leaf conveying mechanism, and finally realizes the single-piece output of the tobacco leaves, that is, the stacked tobacco leaves are separated into pieces and transported one by one to the next process. No manual participation is required in the tobacco leaf segmentation process, which saves production costs and improves production efficiency.

However, those skilled in the art may still make various substitutions and modifications based on the teachings and disclosures of the present invention without departing from the spirit of the present invention. Therefore, the protection scope of the present invention should not be limited to the contents disclosed in the embodiments, but should include various substitutions and modifications that do not depart from the present invention and are covered by the claims of this patent application.
