Description

Technical Field

[0001] This utility model relates to the field of cutting equipment, specifically to a tobacco cutting equipment. Background Technology

[0002] Tobacco cutting equipment is the core equipment in tobacco processing. It is responsible for precisely cutting pre-treated tobacco leaves to ensure that their size, shape, and filling properties meet the specific requirements of various cigarette products.

[0003] The specific shredding process involves stacking tobacco leaves to a certain thickness and then placing them into a tobacco shredding machine for shredding. However, existing tobacco shredding machines require two cuts to cut the tobacco leaves to the required length. The first cut cuts the tobacco leaves into long strips of tobacco, and the second cut cuts the tobacco leaves into smaller segments of the appropriate length. Both cuts require aligning the tobacco leaves and long strips of tobacco, which makes the shredding efficiency extremely low.

[0004] The research objective of this utility model is to design a tobacco shredding cutting device to address the problems existing in the prior art. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a tobacco shredding cutting device, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is: A tobacco shredding cutting device, comprising: The feeding mechanism is used to compress and feed the tobacco leaves; The cutting mechanism includes a rotating component driven to rotate by a rotary drive device, and a plurality of cutting devices disposed on one side of the rotating component and rotated by the rotating component. A cutting gap for inputting the tobacco leaves is formed between the rotating component and the feeding mechanism. Each cutting device includes a first cutting component and a plurality of second cutting components. The first cutting component is used to rotate and cut the tobacco leaves in the cutting gap to form long strips of tobacco. A plurality of cutting zones are formed between the plurality of second cutting components and are used to synchronously rotate and cut the long strips of tobacco to form a plurality of short segments of tobacco. A plurality of feed inlets communicating with the cutting zones are provided through the rotating component. The discharging mechanism includes qualified channels corresponding to several of the feeding ports; the short tobacco shreds sequentially pass through the cutting zone and the feeding ports and fall into the qualified channels for discharging.

[0007] Furthermore, the rotating component is a vertically rotating turntable, and several cutting devices are arranged symmetrically. The first cutting component is plate-shaped with a chamfered edge at one end to form a first cutting surface. The first cutting surface protrudes from one side of the rotating component and corresponds circumferentially to the cutting gap. Several second cutting components are vertically arranged on the first cutting surface with a chamfered edge at one end to form a second cutting surface. One end of several second cutting components is flush with one end of the first cutting component. One end of the first cutting component partially covers one end of the material outlet, and the other end of the material outlet is inclined to have a guiding surface for guiding material toward the qualified channel.

[0008] Furthermore, the feeding mechanism includes a conveying mechanism that forms the cutting gap between one end and the rotating member and is used for laterally conveying the tobacco leaves, and a pressing mechanism for pressing the tobacco leaves at one end of the conveying mechanism. The discharging mechanism also includes a waste channel that is separated from the qualified channel and corresponds to the cutting gap. When the end waste of the tobacco leaves is output to the cutting gap and is not pressed by the pressing mechanism, it falls directly into the waste channel through the cutting gap for discharge.

[0009] Furthermore, the conveying mechanism includes a first frame, a conveyor belt rotatably mounted on the first frame, and a feeding drive device for driving the conveyor belt to rotate. The pressing mechanism includes a second frame, one end of which is pressed down and clamped to one end of the first frame by several springs, and the other end of which extends upward at an inclination away from the rotating component and is rotatably mounted. A pressing belt driven to rotate by the pressing drive device is rotatably mounted on the second frame. The pressing belt is provided with several pressing teeth. The conveying direction of the upper side of the conveyor belt and the lower side of the pressing belt is the same. When the pressing teeth rotate to the lower side of the pressing belt, the tooth ends face the rotating component and are used to press and push the tobacco leaves on the conveyor belt toward the rotating component step by step.

[0010] Furthermore, the conveying mechanism also includes a baffle plate disposed between the two sides of the conveyor belt and the pressure belt, and a protective member covering one end of the conveyor belt. The top two ends of the protective member are provided with arc-shaped recesses that fit into one end of the second frame. The top center of the protective member is recessed with a guide groove corresponding to the conveyor belt. The bottom of the guide groove extends upward at an incline, and the distance between the two side walls gradually decreases towards the rotating member.

[0011] Furthermore, the discharge mechanism also includes a lower housing covering the lower half of the rotating component and an upper housing rotatably connected to the lower housing and covering the upper half of the rotating component. The lower housing is divided by a partition to form the qualified channel and the waste channel corresponding to both sides of the rotating component.

[0012] Therefore, the beneficial effects of this utility model are: 1. By designing the cutting device with a first cutting component and several second cutting components, and driving the cutting device to rotate through a rotating component, the cutting devices continuously rotate and cut the tobacco leaves in the gaps between the cutting components. The first cutting component cuts the tobacco leaves into long strips of tobacco shreds, and simultaneously the second cutting components cut the long strips of tobacco shreds into several small segments of tobacco shreds. This allows the cutting device to achieve the effect of secondary cutting of tobacco leaves in one cut. The setting of the cutting zone and the feed port allows the cut small segments of tobacco shreds to be continuously collected into the qualified channel for discharge, which greatly improves the efficiency of tobacco shredding equipment in cutting tobacco leaves into qualified small segments of tobacco shreds. Furthermore, the rotation of the rotating component allows the cutting of several cutting devices to continue continuously, which greatly improves the cutting efficiency compared to the traditional reciprocating cutting of a single cutter.

[0013] 2. By vertically arranging the rotating component, not only can its floor space be reduced, but the efficiency of cutting short tobacco shreds can also be improved. By perpendicularly arranging several second cutting components to the first cutting surface, the flatness of the cut when the second cutting component cuts long tobacco shreds into several short tobacco shreds can be improved, thus improving the cutting effect. Furthermore, by aligning one end of several second cutting components with the first cutting component, the actions of cutting tobacco leaves into long tobacco shreds and cutting the long tobacco shreds into several short tobacco shreds can be performed simultaneously, ensuring smooth cutting and flatness of the cut surface, and improving cutting stability.

[0014] 3. By setting up a pressing mechanism and a waste channel, when the end waste of the tobacco leaves is output to the cutting gap and is not pressed by the pressing mechanism, it falls directly into the waste channel through the cutting gap for discharge. This achieves automatic screening of the waste section at the end of the tobacco leaves during the cutting process, and separates it from the qualified small tobacco shreds through the qualified channel and the waste channel for discharge, improving the automation of waste section screening and thus ensuring the quality of the finished tobacco shreds.

[0015] 4. By setting up a pressing mechanism and a waste channel, when the end waste of the tobacco leaves is output to the cutting gap and is not compacted by the pressing mechanism, it falls directly into the waste channel through the cutting gap for discharge. The pressing mechanism and the feeding mechanism press the tobacco leaves from top to bottom, so that the thinner end waste of the tobacco leaves cannot be stably compacted by the pressing mechanism during the cutting process. This allows the end waste to fall directly into the waste channel through the cutting gap, either automatically or after being pressed down by the cutting device. This achieves automatic screening of the end waste section of the tobacco leaves, and separates it from the qualified small tobacco shreds through the qualified channel and the waste channel for discharge, improving the automation of waste section screening and thus ensuring the quality of the finished tobacco shreds.

[0016] 5. By adding pressing teeth on the pressing belt, during the process of the feeding mechanism pressing and feeding tobacco leaves, when several pressing teeth rotate to the lower side of the pressing belt, the tooth ends face the rotating part and gradually press and push the tobacco leaves on the conveyor belt toward the rotating part. Thus, through the gradually increasing pressing force of several pressing teeth, the tobacco leaves are pushed to move toward the rotating part with the conveyor belt and input the cutting gap while being stably pressed. At the same time, the pressing and feeding functions are realized, and the pressing stability of the pressing mechanism is improved. Attached Figure Description

[0025] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-8 A tobacco shredding cutting device, comprising: The feeding mechanism is used to compress and feed tobacco leaves, specifically, the tobacco leaves are formed by stacking several tobacco leaves one on top of the other; The cutting mechanism 3 includes a rotating component 32 driven to rotate by a rotary drive device 31, and a plurality of cutting devices disposed on one side of the rotating component 32 and rotated by the rotating component 32. A cutting gap 4 for inputting the tobacco leaves is formed between the rotating component 32 and the feeding mechanism. Each cutting device includes a first cutting component 33 and a plurality of second cutting components 34. The first cutting component 33 is used to rotate and cut the tobacco leaves in the cutting gap 4 to form long strips of tobacco. A plurality of cutting zones are formed between the plurality of second cutting components 34 and are used to synchronously rotate and cut the long strips of tobacco to form a plurality of short segments of tobacco. A plurality of feed inlets 321 communicating with the cutting zones are provided through the rotating component 32. Specifically, the rotary drive device 31 can be a motor. The discharge mechanism 5 includes qualified channels 51 corresponding to a plurality of the feed inlets 321; the short tobacco shreds pass through the cutting zone and the feed inlets 321 in sequence and fall into the qualified channels 51 for discharge.

[0026] The above structure designs the cutting device with a first cutting element 33 and several second cutting elements 34. The rotating element 32 drives the cutting device to rotate and cut the tobacco leaves at the cutting gap 4. The first cutting element 33 cuts the tobacco leaves into long strips of tobacco shreds, and the second cutting elements 34 simultaneously cut the long strips of tobacco shreds into several small segments of tobacco shreds. This allows the cutting device to achieve the effect of secondary cutting of tobacco leaves with one cut. The setting of the cutting zone and the feed port 321 allows the cut small segments of tobacco shreds to be continuously collected into the qualified channel 51 for discharge. This greatly improves the efficiency of the tobacco shredding equipment in cutting tobacco leaves into qualified small segments of tobacco shreds. Furthermore, the rotation of the rotating element 32 allows the cutting of several cutting devices to continue continuously, which greatly improves the cutting efficiency compared to the traditional reciprocating cutting of a single cutter.

[0027] To improve the cutting effect, the rotating component 32 is a vertically rotating turntable, and several cutting devices are arranged symmetrically. The first cutting component 33 is plate-shaped with a chamfered edge at one end to form a first cutting surface 331. The first cutting surface 331 protrudes from one side of the rotating component 32 and corresponds circumferentially to the cutting gap 4. Several second cutting components 34 are vertically arranged on the first cutting surface 331 with a chamfered edge at one end to form a second cutting surface 341. One end of several second cutting components 34 is flush with one end of the first cutting component 33. One end of the first cutting component 33 partially covers one end of the feed opening 321. The other end of the feed opening 321 is inclined to have a guide surface 322 for guiding material toward the qualified channel 51. Specifically, the first cutting component 33 and several second cutting components 34 are integrally formed. The above structure, by vertically arranging the rotating component 32, not only reduces its floor space but also improves the efficiency of cutting short tobacco shreds. By perpendicularly arranging several second cutting components 34 to the first cutting surface 331, the flatness of the cut surface when the second cutting components 34 cut long tobacco shreds into several short tobacco shreds can be improved, thus enhancing the cutting effect. Furthermore, by aligning one end of several second cutting components 34 with one end of the first cutting component 33, the actions of cutting tobacco leaves into long tobacco shreds and cutting the long tobacco shreds into several short tobacco shreds are performed simultaneously and synchronously, ensuring smooth cutting and a flat cut surface, and improving cutting stability.

[0028] In the existing tobacco cutting equipment, the back end of the tobacco leaf is thinner and easily becomes a waste segment because it does not meet the requirements. The existing technology does not have the ability to separate the waste segments that do not meet the requirements during the cutting process, which makes subsequent separation difficult and affects the quality of the finished tobacco product.

[0029] To solve the above technical problems, the feeding mechanism is configured as a pressing feeding method. Specifically, the feeding mechanism includes a conveying mechanism 1 that forms the cutting gap 4 between one end and the rotating member 32 and is used for laterally conveying the tobacco leaves, and a pressing mechanism 2 for pressing the tobacco leaves at one end of the conveying mechanism 1. The discharging mechanism 5 also includes a waste channel 52 that is separated from the qualified channel 51 and corresponds to the cutting gap 4. The above structure, through the setting of the pressing mechanism 2 and the waste channel 52, ensures that when the end waste of the tobacco leaves is output to the cutting gap 4, it is not pressed by the pressing mechanism 2. When the material is tight, it falls directly into the waste channel 52 through the cutting gap 4. The pressing mechanism 2 and the feeding mechanism press the tobacco leaves together from top to bottom. This prevents the thinner end waste from being stably pressed by the pressing mechanism 2 during the cutting process. As a result, the end waste can fall directly into the waste channel 52 through the cutting gap 4 automatically or after being pressed down by the cutting device. This achieves automatic screening of the waste section at the end of the tobacco leaf and separates it from the qualified small tobacco shreds through the qualified channel 51 and the waste channel 52 for discharge. This improves the automation of waste section screening and ensures the quality of the finished tobacco shreds.

[0030] To improve the stability of the pressing mechanism, the conveying mechanism 1 includes a first frame 11, a conveyor belt 12 rotatably mounted on the first frame 11, and a feeding drive device 13 for driving the conveyor belt 12 to rotate. The pressing mechanism 2 includes a second frame 21, one end of which is pulled down and pressed against one end of the first frame 11 by several springs 14, and the other end of which extends upward at an incline away from the rotating component 32 and is rotatably mounted. A pressing belt 22 driven to rotate by the pressing drive device 23 is rotatably mounted on the second frame 21. The pressing belt 22 is provided with several pressing teeth 221. The conveying directions of the upper side of the conveyor belt 12 and the lower side of the pressing belt 22 are the same. Specifically, Both the feeding drive device 13 and the pressing drive device 23 can be motors. The above structure, by adding pressing teeth 221 on the pressing belt 22, allows the pressing mechanism to press and input tobacco leaves during the process of pressing and inputting tobacco leaves. When the pressing teeth 221 rotate to the lower side of the pressing belt 22, the tooth ends face the rotating member 32 and press and push the tobacco leaves on the conveyor belt 12 toward the rotating member 32 in stages. Thus, through the progressively increasing pressing force of the pressing teeth 221, the tobacco leaves are pushed to move toward the rotating member 32 along the conveyor belt 12 and input into the cutting gap 4 while being stably pressed. This achieves both pressing and feeding functions and improves the pressing stability of the pressing mechanism 2. Furthermore, by adjusting the conveying speed of the conveyor belt 12 and the rotation speed of the rotating component 32, the cutting width of the first cutting component 33 can be adjusted, achieving the effect of adjustable tobacco leaf cutting width. Through a number of fixed second cutting components, the long tobacco strips are uniformly cut into a number of fixed-length small tobacco segments by the second cutting component 34, achieving the effect of fixed-length cutting of tobacco strips.

[0031] To improve the pressing effect, the conveying mechanism 1 also includes a baffle 15 disposed between the two sides of the conveyor belt 12 and the pressing belt 22, and a protective member 16 covering one end of the conveyor belt 12. The top two ends of the protective member 16 are provided with arc-shaped recesses with abutment grooves 161 adapted to one end of the second frame 21. The top center of the protective member 16 is recessed with a guide groove 162 corresponding to the conveyor belt 12. The bottom of the guide groove 162 is inclined upward and the distance between the two side walls gradually decreases towards the rotating member 32. The above structure, through the setting of the protective component 16, uses the abutment groove 161 for the pressing mechanism 2 to abut and press down, which not only improves the stability of the pressing mechanism 2 pressing down, but also protects the conveyor belt 12 from being crushed. The setting of the baffle 15 and the guide groove 162 forms a pressing space that gradually narrows in the direction of the rotating component 32, and also gradually narrows in the direction of the rotation. This improves the effect of the pressing space on aligning and flattening the tobacco leaves formed by stacking several tobacco leaves, and improves the density and compactness of the tobacco leaves input to the cutting gap 4.

[0032] To improve the safety of the tobacco cutting equipment, the discharge mechanism 5 further includes a lower housing 53 covering the lower half of the rotating component 32, and an upper housing 54 rotatably connected to the lower housing 53 and covering the upper half of the rotating component 32. The lower housing 53 is divided by a partition to form a qualified channel 51 and a waste channel 52 corresponding to both sides of the rotating component 32. This design, with the upper housing 54 and lower housing 53 covering the rotating component 32, prevents the rotating component 32 from posing a safety threat to workers during rotation, thus improving safety. Furthermore, the rotatable upper housing 54 allows workers to easily open it for inspection and maintenance of the rotating component 32 and the cutting device.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
