Description

Technical Field

[0001] This utility model relates to the field of tobacco sheet quality inspection technology, and in particular to a single-sheet feeding device for quality inspection of tobacco sheets after loosening and rehydration processing. Background Technology

[0002] In the tobacco processing technology, loosening and rehydration is a key step, and its quality directly affects the stability of subsequent processes and the quality of the final tobacco product. To achieve automated evaluation of the quality of loosening and rehydration, existing technologies typically rely on continuous and extensive image acquisition of tobacco leaf samples (i.e., individual tobacco leaves). Image analysis technology is used to determine key parameters such as the processing status, uniformity, and moisture content of each tobacco leaf, and data is continuously accumulated to provide data support for process improvement and quality traceability.

[0003] Currently, obtaining tobacco leaf samples on tobacco processing lines still mainly relies on manual sorting and sampling. This method is not only inefficient and unable to meet the needs of large-scale, continuous testing, but also prone to subjective errors due to manual operation, making it difficult to guarantee the representativeness and consistency of sample selection. Furthermore, manual sampling suffers from high labor intensity, high costs, and incompatibility with the pace of automated production. Therefore, there is an urgent need for a device capable of automatically feeding single tobacco leaves to address the shortcomings of low sample acquisition efficiency and insufficient automation in existing technologies, providing reliable technical support for the quality testing of tobacco leaves after loose rehydration processing.

[0004] Therefore, this application proposes a single-sheet feeding device for quality testing of tobacco sheets after loose rehydration processing. Utility Model Content

[0007] The initial vibration distribution plate includes a multi-stage positioning frame fixedly installed on the top of the side positioning plate. A comprehensive feeding and conveying plate is fixedly installed on the top of the multi-stage positioning frame. Storage hoppers are fixedly installed on both sides of the comprehensive feeding and conveying plate. The storage hoppers have slides inside.

[0008] The auxiliary paddle assembly includes an auxiliary storage rack and an insert block that are slidably installed inside the storage hopper via a slide rail. The auxiliary storage rack and the insert block are connected in an interlocking state. A limit box is fixedly installed on the side of the auxiliary storage rack and the insert block away from the storage box. A bidirectional connecting block is slidably installed inside the limit box. A positioning rod is fixedly installed inside the bidirectional connecting block. A paddle frame is fixedly installed on the outside of the positioning rod.

[0009] Optionally, the quality inspection single-piece feeding support assembly further includes a single-piece feeding support platform fixedly installed on one side of the side positioning plate, and upper and lower positioning rings are fixedly installed inside the single-piece feeding support platform.

[0010] Optionally, the initial vibration distribution plate may further include a first pulse electromagnetic component fixedly installed on the side of the multi-stage positioning frame facing the upper and lower positioning rings, and the output end of the first pulse electromagnetic component is fixedly installed at the bottom of the integrated feeding and transmission plate.

[0011] Optionally, the positioning transmission drive assembly includes storage boxes fixedly installed on both sides of the integrated feeding transmission plate. A central positioning frame is fixedly installed in the center of the storage box. Two positioning guide rods are fixedly installed inside the central positioning frame. The positioning guide rods pass through both sides of the central positioning frame and are fixedly installed on the inner wall of the storage box.

[0012] Optionally, a positioning rotating column is fixedly installed between the central positioning frame and the storage box, and a bidirectional positioning plate is rotatably installed on the outer side of the positioning rotating column. A set of bidirectional hinge rods is hinged to the outer side of the bidirectional positioning plate.

[0013] Optionally, a second positioning frame is hinged to the side of the bidirectional hinged rod away from the bidirectional positioning plate. The second positioning frame is slidably installed on the outside of the positioning guide rod. A slide rail is fixedly installed inside the storage box, and the second positioning frame is slidably installed inside the slide rail.

[0014] Optionally, a first positioning frame is slidably installed on the side of the positioning guide rod away from the second positioning frame. There are two sets of bidirectional hinge rods, with the other set of bidirectional hinge rods hinged to the outside of the first positioning frame. An electric telescopic assembly is fixedly installed on one side of the second positioning frame, and the telescopic end of the electric telescopic assembly passes through one end of the central positioning frame and is fixedly installed on the outer wall of the second positioning frame.

[0015] Optionally, a spring is fixedly installed between the limiting box and the bidirectional connecting block, a magnetic block and an arc-shaped guide frame are fixedly installed on the surface of the storage hopper, the arc-shaped guide frame is located directly below the magnetic block, and a spherical guide block is fixedly installed on the side of the bidirectional connecting block away from the positioning rod.

[0016] Optionally, a circular vibrating disk assembly is installed on the top of the single-piece feeding support assembly for quality inspection. The circular vibrating disk assembly includes a circular vibrating disk fixedly installed inside the upper and lower positioning rings. A second pulse electromagnetic assembly is fixedly installed between the circular vibrating disk and the single-piece feeding support platform. A circular vibrating disk feeding plate is provided inside the circular vibrating disk.

[0017] Optionally, a shifting assembly is installed at the bottom of the auxiliary shifting assembly. The shifting assembly includes multiple sets of threaded guide posts fixedly installed at the bottom of the shifting frame. An elastic shifting post is slidably installed at the bottom of the threaded guide post. An auxiliary spring is fixedly installed between the elastic shifting post and the threaded guide post. A mating post is fixedly installed on one side of the elastic shifting post. The mating post is slidably installed inside the thread of the threaded guide post. The thread angles on the surfaces of the multiple sets of threaded guide posts are different.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The spring force pulls back, enabling the sorting assembly to adaptively clamp the tobacco sheets. As the two sets of limit boxes move away from the center of the storage hopper, they exert a pushing force on the tobacco sheets along the Y-axis, which further causes the tobacco sheet pile to separate outwards. This separation of the tobacco sheets is beneficial for the detection of tobacco sheet quality.

[0020] 2. The roughly separated tobacco sheets can be transferred to the later detection component by the circular vibrating plate for further processing. At the same time, the automated feeding process reduces the reliance on manual operation, reduces labor intensity and labor costs, and provides economic benefits for enterprises to achieve intelligent production.

[0021] 3. The flexible separating column rotates along with the tobacco sheet attached below. Due to the different thread angles of the threaded guide column, the individual tobacco sheets attached to the multiple sets of flexible separating columns rotate at different angles. This causes gaps to be created between these separated tobacco sheets in the Y-axis direction. Thus, through efficient and stable single-sheet sample supply, a reliable guarantee is provided for batch data collection and processing quality evaluation, which helps to form data accumulation support and further promote the optimization and improvement of tobacco leaf processing technology.

[0034] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0035] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0036] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figure 1 and Figure 2As shown, this utility model proposes a single-sheet feeding device for quality inspection of loosely processed tobacco sheets. It includes a single-sheet feeding support assembly 1, which includes a side positioning plate 103. An initial vibration distribution plate 2 is mounted on the top of the single-sheet feeding support assembly 1. Two sets of positioning transmission drive assemblies 3 are mounted on both sides of the initial vibration distribution plate 2. An auxiliary prying plate assembly 4 is mounted on the side of each set of positioning transmission drive assemblies 3 facing each other. The single-sheet feeding support assembly 1 also includes a single-sheet feeding support platform 101 fixedly mounted on one side of the side positioning plate 103. Upper and lower positioning rings 102 are fixedly mounted inside the single-sheet feeding support platform 101. The initial vibration distribution plate 2 includes a multi-stage positioning frame 203 fixedly mounted on the top of the side positioning plate 103. A comprehensive feeding transmission plate 202 is fixedly mounted on the top of the multi-stage positioning frame 203. Storage hoppers 201 are fixedly mounted on both sides of the comprehensive feeding transmission plate 202. The storage hoppers 201 have slides inside. The initial vibration distribution plate 2 also includes a first pulse electromagnetic component 204 fixedly installed on the side of the multi-stage positioning frame 203 facing the upper and lower positioning rings 102. The output end of the first pulse electromagnetic component 204 is fixedly installed at the bottom of the integrated feeding transmission plate 202. The top of the quality inspection single-piece feeding support component 1 is equipped with a circular vibrating plate component 5. The loose and rehydrated tobacco sheets are quantitatively conveyed to the storage hopper 201. Due to the large volume of the tobacco sheets and the fact that some defective products are still damp after being moistened, the tobacco sheets are more likely to stick together. In the existing processing method, workers manually separate the tobacco sheets before inspection, which is inefficient. The tobacco sheets are first put into the integrated feeding transmission plate 202. Due to the obstruction of the storage hopper 201, the tobacco sheets can only be conveyed along the fixed outlet of the storage hopper 201. The first pulse electromagnetic component 204 guides the vibration of the integrated feeding transmission plate 202 through the action of electromagnetic field. The tobacco sheets are initially separated under the action of vibration and then fall into the interior of the circular vibrating plate component 5 for secondary processing.

[0040] like Figure 3 and Figure 4As shown, the positioning transmission drive assembly 3 includes a storage box 301 fixedly installed on both sides of the integrated feeding transmission plate 202. A central positioning frame 302 is fixedly installed in the center of the storage box 301. Two positioning guide rods 308 are fixedly installed inside the central positioning frame 302. The positioning guide rods 308 pass through the central positioning frame 302 and are fixedly installed on both sides of the storage box 301. A positioning rotating column 306 is fixedly installed between the central positioning frame 302 and the storage box 301. A bidirectional positioning plate 307 is rotatably installed on the outside of the positioning rotating column 306. A set of bidirectional hinge rods 309 are hinged to the outside of the bidirectional positioning plate 307. The bidirectional hinge rods 309 are located away from the outside of the bidirectional positioning plate 307. A second positioning frame 304 is hinged to one side of the bidirectional positioning plate 307. The second positioning frame 304 is slidably mounted on the outside of the positioning guide rod 308. A slide rail 305 is fixedly installed inside the storage box 301. The second positioning frame 304 is slidably mounted inside the slide rail 305. A first positioning frame 303 is slidably mounted on the side of the positioning guide rod 308 away from the second positioning frame 304. There are two sets of bidirectional hinge rods 309. The other set of bidirectional hinge rods 309 is hinged to the outside of the first positioning frame 303. An electric telescopic assembly 310 is fixedly mounted on one side of the second positioning frame 304. The telescopic end of the electric telescopic assembly 310 passes through one end of the central positioning frame 302. The auxiliary shifting assembly 4 is mounted on the outer wall of the second positioning frame 304, and the bottom of the auxiliary shifting assembly 4 is equipped with a shifting assembly 6. As the tobacco leaves fall into the storage hopper 201, the distance between the second positioning frame 304 and the first positioning frame 303 is at its maximum, which facilitates the accumulation of a fixed amount of tobacco leaves within this distance. The telescopic end of the electric telescopic assembly 310 passes through one end of the central positioning frame 302, driving the first positioning frame 303 to slide along the positioning guide rod 308. At the same time, the slide rail 305 limits the sliding position of the second positioning frame 304 and the first positioning frame 303, making the sliding of the second positioning frame 304 and the first positioning frame 303 more stable. During the sliding process of the positioning frame 303, the bidirectional hinge rod 309 will be deflected. Since the central positioning frame 302 is fixed, as the distance between the first positioning frame 303 and the central positioning frame 302 changes, the corresponding bidirectional positioning plate 307 will drive the positioning rotating column 306 to rotate along the central positioning frame 302. Since the bidirectional hinge rods 309 on both sides of the bidirectional positioning plate 307 are symmetrically arranged along the center of the bidirectional positioning plate 307, the other set of bidirectional hinge rods 309 will be deflected by the same tension, causing the second positioning frame 304 to slide along the positioning guide rod 308, and the first positioning frame 303 and the positioning guide rod 308 slide in opposite directions.

[0041] like Figures 5-10As shown, the auxiliary paddle assembly 4 includes an auxiliary storage rack 402 and an insert block 403 slidably mounted inside the storage hopper 201 via a slide rail. The auxiliary storage rack 402 and the insert block 403 are connected in an interlocking state. A limit box 405 is fixedly installed on the side of both the auxiliary storage rack 402 and the insert block 403 away from the storage box 301. A bidirectional connecting block 409 is slidably mounted inside the limit box 405. A positioning rod 404 is fixedly mounted inside the bidirectional connecting block 409. A paddle frame 401 is fixedly mounted on the outside of the positioning rod 404. A spring 408 is fixedly installed between the limit box 405 and the bidirectional connecting block 409. A magnetic block 406 and an arc-shaped guide frame 407 are fixedly mounted on the surface of the storage hopper 201. The arc-shaped guide frame 407 is located directly below the magnetic block 406. A spherical guide block 410 is fixedly installed on the side of the bidirectional connecting block 409 away from the positioning rod 404. During the sliding process of the first positioning frame 303 and the second positioning frame 304, the rod 403 slides along the interior of the auxiliary storage frame 402. The rod 403 and the auxiliary storage frame 402 always block the opening of the slide, preventing tobacco leaves from entering the storage box 301. Before the tobacco leaves are added, the distance between the first positioning frame 303 and the second positioning frame 304 is at its maximum. As the metered tobacco leaves are located in the center of the storage hopper 201, the first pulse electromagnetic component 204 drives the storage hopper 201 to vibrate, causing the tobacco leaves to disperse. At this time, the auxiliary storage frame 406... 2. The insertion block 403 drives the corresponding limiting box 405 to move towards the center. The spherical guide block 410 first contacts the arc-shaped track of the arc-shaped guide frame 407. Note that the spring 408 and the arc-shaped guide frame 407 are not on the same plane, so the spring 408 does not contact the arc-shaped guide frame 407. The spherical guide block 410 moves upward along the undulating arc-shaped track of the arc-shaped guide frame 407. The spherical guide block 410 drives the lever frame 401 upward through the positioning rod 404, causing the lever frame 401 to be far from the metered tobacco sheet. Therefore, the lever frame 401 and the lower dispensing assembly 6 will not contact the tobacco sheet, preventing the dispensing assembly 6 from contacting the tobacco sheet and causing friction that could cause the tobacco sheet to be pushed towards the storage material. The pressure in the center of hopper 201 causes damage to the tobacco sheets. At the same time, the bidirectional connecting block 409 and the magnetic block 406 generate magnetic attraction, thereby improving the stability of the ball guide block 410 sliding along the arc guide frame 407. When the ball guide block 410 disengages from the magnetic block 406 and the arc guide frame 407, the spring 408 and gravity pull the paddle holder 401 and the sorting assembly 6 back to their original positions to contact the tobacco sheets. Due to the elastic pull of the spring 408, the sorting assembly 6 can adaptively clamp the tobacco sheets. As the two sets of limit boxes 405 move away from the center of the storage hopper 201, they give the tobacco sheets a thrust along the Y-axis, thereby further separating the tobacco sheet pile outward, which facilitates the separation of the tobacco sheets and is beneficial to the detection of tobacco sheet quality.

[0042] like Figure 6As shown, the circular vibrating disk assembly 5 includes a circular vibrating disk 501 fixedly installed inside the upper and lower positioning rings 102. A second pulse electromagnetic component 502 is fixedly installed between the circular vibrating disk 501 and the single-piece feeding support table 101. A circular vibrating disk feeding plate 503 is provided inside the circular vibrating disk 501. The tobacco sheets located in the storage hopper 201 enter the circular vibrating disk 501. Under the action of the second pulse electromagnetic component 502, the tobacco sheets falling into the circular vibrating disk 501 are transported upward along the spiral track on the surface of the circular vibrating disk 501. It should be noted that the surface of the circular vibrating disk 501 is a spiral upward track, which is the outlet of the circular vibrating disk 501. The highest point is at the center of the vibrating disc 501, while the lowest point is at the center. When passing through the vibrating disc feeder 503, clumps of tobacco sheets that are too large to pass through the vibrating disc 501 are pushed back into the center of the vibrating disc 501 for further separation. This is the working principle of the existing vibrating disc, which will not be described in more detail here. The roughly separated tobacco sheets can then be transferred to the subsequent inspection component through the vibrating disc feeder 503 for further processing. At the same time, the automated feeding process reduces the reliance on manual operation, lowers labor intensity and labor costs, and provides economic benefits for enterprises to achieve intelligent production.

[0043] In this embodiment, as Figure 11 As shown, the dispensing assembly 6 includes multiple sets of threaded guide posts 604 fixedly installed at the bottom of the dispensing frame 401. An elastic dispensing post 601 is slidably installed at the bottom of the threaded guide post 604. An auxiliary spring 603 is fixedly installed between the elastic dispensing post 601 and the threaded guide post 604. A mating post 602 is fixedly installed on one side of the elastic dispensing post 601, and the mating post 602 is slidably installed inside the thread of the threaded guide post 604. The thread angles on the surfaces of the multiple sets of threaded guide posts 604 are different. It is noted that the elastic dispensing post 601 applies a pressure of 10mN-50mN to the tobacco sheet. When the limiting box 405 moves the ball guide block 410 to the arc-shaped guide frame 407, the ball guide block 410 is squeezed by the arc-shaped track under the arc-shaped guide frame 407, applying greater pressure to the tobacco sheet. Since there are two sets of limiting... At its maximum spacing between the position boxes 405, the tobacco sheets are essentially separated into individual pieces. While the elastic distribution column 601 applies pressure to the tobacco sheets, it slides towards the inside of the threaded guide column 604 under the limit of the auxiliary spring 603. The insertion column 602 rotates along the thread of the threaded guide column 604. The elastic distribution column 601 then rotates the tobacco sheets attached below it. Due to the different thread angles of the threaded guide column 604, the individual tobacco sheets attached to the multiple sets of elastic distribution columns 601 rotate at different angles, resulting in gaps between these separated tobacco sheets in the Y-axis direction. This provides a reliable guarantee for batch data collection and processing quality evaluation through efficient and stable single-sheet sample supply, which helps to form data accumulation support and further promote the optimization and improvement of tobacco processing technology.

[0044] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
