Abstract

This invention belongs to the field of cigarette production technology and discloses an adjustable stem removal and reuse device, including a device housing, a stem sorting mechanism, a stem arrangement mechanism, and a stem reuse mechanism. The stem sorting mechanism includes a rotating mesh cage located in the central part of the inner cavity of the device housing. The rotating mesh cage consists of three sections of tubular screens of the same diameter—a fine material tubular screen, a medium material tubular screen, and a coarse material tubular screen—connected concentrically from right to left. The screening mesh openings of the fine, medium, and coarse material tubular screens are rectangular slotted, and the length direction of the rectangular slots is parallel to the axis of the rotating mesh cage.

Description

Technical Field

[0001] This invention relates to the field of cigarette production technology, and in particular to an adjustable stem removal and reuse device. Background Technology

[0002] The stems are the coarse, hard veins of tobacco leaves. Nicotine, solanol, nicotinic acid, pectin, and plant proteins can be extracted from them. Stem removal machines are auxiliary mechanical devices in tobacco processing equipment, mainly used to remove stems and large foreign objects from the raw material, improving the purity of the tobacco shreds. They are widely used in the tobacco processing of cigarette factories.

[0003] Currently, there are two main types of tobacco stem processing equipment. One type uses a vibrating screen structure. When the tobacco stems pass through a vibrating screen with slatted mesh, the stems and large foreign objects are retained by the screen, while the stems that meet the specifications fall through the screen into a container below, thus separating the tobacco from the stems. In this case, the width of the mesh openings of the vibrating screen is the standard for controlling the quality of the tobacco. The other type uses a rolling screen structure. The stems are placed in a rotating mesh cage. As the cage rotates, the stems tumble and fall through the gaps into a container below, again separating the tobacco from the stems. However, current tobacco stem processing equipment cannot perform fine and adjustable screening of the raw material to multiple specifications. Manual further screening of the sifted raw material is required before reuse, resulting in low overall screening efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a device for removing and reusing stalks with adjustable specifications, so as to solve the problems mentioned in the background art.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0042] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] like Figures 1 to 9As shown, the present invention provides a stalk removal and reuse device with adjustable specifications, including a device housing 1, a stalk sorting mechanism 2, a stalk arrangement mechanism 3, and a stalk reuse mechanism 4. The sorting mechanism 2 includes a rotating mesh cage 21 located in the central shaft of the inner cavity of the device housing 1. The rotating mesh cage 21 is composed of three sections of tubular screens of the same diameter: a fine material tubular screen 211, a medium material tubular screen 212, and a coarse material tubular screen 213, connected concentrically from right to left. A baffle ring is fixed to the inner wall of the junction of the fine material tubular screen 211, medium material tubular screen 212, and coarse material tubular screen 213. The screening mesh openings of the fine material tubular screen 211, medium material tubular screen 212, and coarse material tubular screen 213 are rectangular slots, and the length direction of the rectangular slots is parallel to the axial direction of the rotating mesh cage 21. The width of the rectangular slots in the medium material tubular screen 212 is 1.5 times the width of the rectangular slots in the fine material tubular screen 211. The width of the rectangular slots in the coarse material tubular screen 211 is... The width of the rectangular slot of 3 is 1.5 times the width of the rectangular slot of the tubular screen 212; the stem sorting mechanism 3 includes a fine stem vibration groove 31, a medium stem vibration groove 32 and a coarse stem vibration groove 33 movably disposed on the bottom wall of the device housing 1. The fine stem vibration groove 31, the medium stem vibration groove 32 and the coarse stem vibration groove 33 are parallel to each other and perpendicular to the axis of the rotating mesh cage 21 in the horizontal direction. The fine stem vibration groove 31 is located directly below the fine material tubular screen 211, the medium stem vibration groove 32 is located directly below the medium material tubular screen 212, and the coarse stem vibration groove 33 is located directly below the coarse material tubular screen 213. The front ends of the fine stem vibration groove 31, the medium stem vibration groove 32 and the coarse stem vibration groove 33 all extend out of the front wall of the device housing 1 and are connected to the stem recycling mechanism 4.

[0044] In this embodiment, the stems and shanks awaiting removal and reuse are fed into the open end of the fine material tubular screen 211 of the rotating mesh cage 21. During the rotation of the rotating mesh cage 21, the stems and shanks pass sequentially through the fine material tubular screen 211, the medium material tubular screen 212, and the coarse material tubular screen 213. In the fine material tubular screen 211 section, smaller-diameter stems and shanks fall through the rectangular slots into the fine stem vibration groove 31 directly below. In the medium material tubular screen 212 section... Medium-diameter stems fall from the rectangular slots of this section into the medium stem vibration trough 32 directly below. In the coarse material tubular screen 213 section, larger-diameter stems fall from the rectangular slots of this section into the coarse stem vibration trough 33 directly below, thus achieving stem sorting. The sorted stems are then conveyed to their front ends by the fine stem vibration trough 31, medium stem vibration trough 32, and coarse stem vibration trough 33, and then enter the corresponding stem recycling mechanism 4 for classified reuse.

[0045] For example, smaller diameter stems can be recycled into tobacco processing equipment and mixed with raw tobacco to produce tobacco products of different grades. Medium or larger diameter stems can be crushed and then extracted to extract nicotine, solanol, nicotinic acid, pectin, plant protein and other components.

[0046] In some embodiments, the sorting mechanism 2 further includes a fixed support rod 22 fixed to the left end of the bottom wall of the device housing 1 and a lifting push rod 23 fixed to the right end of the bottom wall of the device housing 1. The fixed support rod 22 is fixedly connected to the central axis of the rotating mesh cage 21 located at the left end of the coarse tubular screen 213 via a swing shaft 24. The telescopic part at the top of the lifting push rod 23 is fixedly connected to a semi-circular frame 25. The top of the semi-circular frame 25 supports the outer wall of the right end of the fine tubular screen 211 via a self-deflecting roller 26. A screening motor 27 is fixedly connected to the outer wall of the left end of the device housing 1. The output shaft of the screening motor 27 is fixedly connected to the swing shaft 24 via a double-joint universal coupling 28.

[0047] In this embodiment, when sorting the stems, the screening motor 27 is started. The screening motor 27 drives the rotating mesh cage 21 to rotate through the double-section universal coupling 28 and the swing shaft 24. At this time, the raw material stems that need to be rejected and reused are put into the open end of the fine material tubular screen 211. The stems with smaller diameters fall from the screening mesh holes on the side wall of the fine material tubular screen 211. Then, the stems with larger diameters than the screening mesh holes on the side wall of the fine material tubular screen 211 continue to roll to the medium material tubular screen 212 and the coarse material tubular screen 213, and are then further screened by the screening mesh holes on the side wall of the medium material tubular screen 212 and the coarse material tubular screen 213.

[0048] During the aforementioned rotary screening process, the right end of the rotary screen cage 21 can be raised or lowered by the lifting push rod 23, the semi-circular frame 25, and the self-deflecting roller 26 from the outer wall of the fine material tubular screen 211, so that the axis of the rotary screen cage 21 forms an angle in the vertical plane, so that the stems can gradually move from the end of the fine material tubular screen 211 through the medium material tubular screen 212 to the coarse material tubular screen 213, and the sorting is completed in this process; and the angle of the rotary screen cage 21 in the vertical plane can be changed by the lifting push rod 23 to adapt the fineness and sorting efficiency of the stems, so as to controllably sort them according to the standards of stem rejection and reuse.

[0049] Among them, since the inner wall of the junction of the fine material tubular screen 211, the medium material tubular screen 212 and the coarse material tubular screen 213 is fixed with a baffle ring, the stems and tangles in the fine material tubular screen 211 can be fully rotated and screened before entering the medium material tubular screen 212 for further screening. At the same time, the stems and tangles in the medium material tubular screen 212 can be fully rotated and screened before entering the coarse material tubular screen 213 to complete the final screening.

[0050] In some embodiments, the stem sorting mechanism 3 further includes a crankshaft 34 rotatably disposed at the bottom of the inner wall of the device housing 1. Three parallel connecting rods are rotatably connected to the crankshaft 34. The three connecting rods are respectively connected to the rear ends of the fine stem vibration groove 31, the medium stem vibration groove 32 and the coarse stem vibration groove 33 by pins. A vibration motor 35 is fixedly connected to one end of the crankshaft 34.

[0051] In this embodiment, when sorting the stems, the vibration motor 35 can be started. The vibration motor 35 drives the crankshaft 34 to rotate, and then drives the fine stem vibration groove 31, medium stem vibration groove 32 and coarse stem vibration groove 33 to move back and forth through the three connecting rods. This vibrates and straightens the sorted stems, making the length direction of the randomly stacked stems parallel to the axis direction of the horizontal plane of the rotating mesh cage 21, which is conducive to sorting, bundling and recycling.

[0052] During the rotation of the crankshaft 34, the fine stem vibration groove 31 and the coarse stem vibration groove 33 move synchronously, while the middle stem vibration groove 32 located between them moves in the opposite direction. A counterweight is installed on the middle stem vibration groove 32 so that the mass of the middle stem vibration groove 32 is equal to the mass of the fine stem vibration groove 31 and the coarse stem vibration groove 33. Therefore, the motion inertia of the fine stem vibration groove 31, the middle stem vibration groove 32 and the coarse stem vibration groove 33 can cancel each other out, which greatly reduces the eccentric vibration generated during horizontal vibrating screening and reduces the noise and mechanical wear of the working site.

[0053] In some embodiments, a follow-up cleaning mechanism 5 parallel to its outer wall is provided on the side of the rotating mesh cage 21. The follow-up cleaning mechanism 5 includes a deflection rail 51, a translation slide 52 is movably fitted on the deflection rail 51, a translation motor 53 is fixedly connected to one end of the deflection rail 51, a translation screw 54 is fixedly connected to the output shaft of the translation motor 53, and the translation screw 54 is screwed to the translation slide 52. A high-pressure nozzle 55 is fixedly provided on one side of the translation slide 52, and a rolling brush 56 is rotatably connected to the other side of the translation slide 52. The high-pressure nozzle 55 is perpendicular to the center of the rotating mesh cage 21. A drive turbine 57 is coaxially connected to the rolling brush 56. A drive nozzle 58 is connected to the tangential direction of the drive turbine 57. The drive nozzle 58 is connected to the air source of the high-pressure nozzle 55.

[0054] As mentioned above, because the sides of the stem are irregular flexible bodies, some stems with a diameter or width slightly larger than the rectangular slot will get stuck in the rectangular slot, affecting the screening of the rotating mesh cage 21. Therefore, it is necessary to clean the stems stuck in the rectangular slot frequently.

[0055] In this embodiment, a high-pressure air source supplies air to the high-pressure nozzle 55, which blows air into the rectangular slots on the side walls of the fine material tubular screen 211, the medium material tubular screen 212, and the coarse material tubular screen 213. This blows out the stuck stems and crannies. For stems and crannies that cannot be blown out, a rolling brush 56 is used to brush them away, allowing the stems and crannies stuck on the outer wall of the rotating mesh cage 21 to return to their interior, and then the screening is carried out again. The translation slide 52, driven by the translation motor 53 and the translation screw 54, moves back and forth on the sides of the rotating mesh cage 21, thereby driving the high-pressure nozzle 55 and the rolling brush 56 to blow air and clean the rectangular slots one by one, ensuring that the rotating mesh cage 21 is not blocked by stems and crannies, and enabling it to sort stems and crannies stably over a long period of time. In addition, the high-pressure nozzle 55 and the rolling brush 56 share the same high-pressure air source, which reduces costs and ensures the continuity of cleaning.

[0056] In some embodiments, the telescopic part at the top of the lifting push rod 23 is fixedly connected to the lifting support 59, the left end of the deflection rail 51 is rotatably connected to the left side of the rear wall of the device housing 1, and the bottom side of the right end of the deflection rail 51 overlaps the top of the lifting support 59.

[0057] Therefore, when the lifting push rod 23 pushes the right end of the rotating mesh cage 21 to rise, it also pushes the right end of the deflection rail 51 to rise through the lifting support 59, so that the up and down movement of the deflection rail 51 is synchronized with the rotating mesh cage 21. During this process, the high-pressure nozzle 55 and the rolling brush 56 continue to blow air and clean the rectangular slot to ensure that the rotating mesh cage 21 is not blocked by the obstruction.

[0058] In some embodiments, the stem recycling mechanism 4 includes a horizontal fixed shaft 41, which is parallel to the axis of the rotating mesh cage 21 in the horizontal direction. The horizontal fixed shaft 41 is connected in series from right to left with a fine stem spoke wheel 42, a medium stem spoke wheel 43, and a coarse stem spoke wheel 44. The fine stem spoke wheel 42 corresponds to the opening of the fine stem vibration groove 31 and is located directly below the fine stem vibration groove 31. The medium stem spoke wheel 43 corresponds to the opening of the medium stem vibration groove 32 and is located directly below the medium stem vibration groove 32. The coarse stem spoke wheel 44 corresponds to the opening of the coarse stem vibration groove 33 and is located directly below the coarse stem vibration groove 33.

[0059] The fine-stem spoke disc 42, the medium-stem spoke disc 43, and the coarse-stem spoke disc 44 are each divided into several independent stem-carrying cavities by their internal spokes and partitions. The fine stems vibrating from the opening of the fine-stem vibration groove 31 fall into the fine-stem spoke disc 42. After the first partitioned cavity of the fine-stem spoke disc 42 is full of stems, the fine-stem spoke disc 42 can be rotated to the next partitioned cavity to continue holding the fallen stems. At this time, the stems in the first partitioned cavity of the fine-stem spoke disc 42 can be quantitatively removed by a clamp for bundling and packaging. Similarly, after the first partitioned cavity of the medium-stem spoke disc 43 and the coarse-stem spoke disc 44 is full of stems, it can be rotated to the next partitioned cavity. At this time, the stems in the previous partitioned cavity can also be processed accordingly.

[0060] In some embodiments, a screw conveyor 6 is fixedly installed at the right end of the outer wall of the device housing 1, and the output port of the screw conveyor 6 extends to the inner tube opening of the fine material tubular screen 211. The screw conveyor 6 can uniformly convey the raw material stems through the fine material tubular screen 211 into the rotating mesh cage 21, and then perform stem sorting, stem arrangement and stem reuse according to the above process.

[0061] In some embodiments, a dust absorption mechanism 7 is installed on the top of the device housing 1. The dust absorption mechanism 7 is used to suck out the dust generated during the removal of stems and keeps the environment of the removal and reuse workplace clean.

[0062] In some embodiments, comb-tooth isolation plates are fixedly provided on the inner bottom walls of the fine stem vibration groove 31, the medium stem vibration groove 32, and the coarse stem vibration groove 33. Since the width of the fine stem vibration groove 31, the medium stem vibration groove 32, and the coarse stem vibration groove 33 is several times or even tens of times the length of the stem bend, the stem bends that fall into them are easily stuck together again under vibration. After the comb-tooth isolation plates are provided, the interval between the two comb-tooth isolation plates can be set to 1 to 1.5 times the length of the stem bend. At this time, the stem bend can fall between the two comb-tooth isolation plates during vibration, and be sorted more quickly, and then connect with the stem bend receiving cavity in the fine stem spoke wheel 42, the medium stem spoke wheel 43, and the coarse stem spoke wheel 44.

[0063] In some embodiments, a semi-enclosed annular baffle is fixedly provided between the fine stem vibration trough 31 and the medium stem vibration trough 32, and between the medium stem vibration trough 32 and the coarse stem vibration trough 33. The semi-enclosed annular baffle can isolate stems of different specifications that fall during the screening process and avoid secondary mixing.

[0064] The adjustable stem removal and reuse device provided by this invention features a rotating mesh cage 21 with an adjustable pitch angle. The mesh size of the rotating mesh cage 21 increases proportionally from the inlet to the outlet, allowing for the screening of stems of multiple sizes. The angle of the rotating mesh cage 21 can be adjusted to suit the fineness and efficiency of stem sorting, enabling controllable sorting according to stem removal and reuse standards. A follow-up cleaning mechanism 5, which rotates with the rotating mesh cage 21, is installed on one side of the rotating mesh cage 21. High-pressure nozzles 55 and rolling brushes 56 on the follow-up cleaning mechanism 5 blow air and clean the rectangular slots one by one, ensuring stable stem sorting in the rectangular slots over a long period. Furthermore, the high-pressure nozzles 55 and rolling brushes 56 share the same high-pressure air source, reducing cleaning costs and ensuring the sustainability of stem recycling and reuse. Through stem sorting… The vibrating motor 35 and crankshaft 34 then drive the fine stem vibrating trough 31, medium stem vibrating trough 32, and coarse stem vibrating trough 33 to reciprocate, thus straightening the sorted stems through vibration. This facilitates the sorting, bundling, packaging, and recycling of the stems. During the process of straightening the stems through vibration, the fine stem vibrating trough 31 and coarse stem vibrating trough 33 move synchronously, while the medium stem vibrating trough 32, located between the fine stem vibrating trough 31 and coarse stem vibrating trough 33, moves in the opposite direction. A counterweight is installed on the medium stem vibrating trough 32, making its mass equal to that of the fine stem vibrating trough 31 and coarse stem vibrating trough 33. Therefore, the moments of inertia of the fine stem vibrating trough 31, medium stem vibrating trough 32, and coarse stem vibrating trough 33 can cancel each other out, significantly reducing the eccentric vibration generated during horizontal vibrating screening, lowering noise and mechanical wear at the work site, and improving the utilization rate of the equipment.

Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
