TECHNICAL FIELD
[0001] The utility model relates to a tobacco leaf sorting and impurity removing platform. BACKGROUND
[0002] Tobacco production enterprises need to manually select the tobacco leaves before production, and each tobacco enterprise has corresponding standards for manual tobacco leaf selection and control technology. In the manual selection process, selected leaves are suitable for high-end brand tobacco leaves; unselected leaves are not suitable for high-end brand requirements but have value and can be downgraded for use in other low-end brands; and valueless tobacco leaves, stems and sundries are classified as scrap and disposed.
[0003] Traditional sorting tables are simple table structures that manually sort baled tobacco leaves. The existing sorting table surface is not easy to clean, and cleaning generates dust. In addition, some recyclable tobacco fragments are also removed as garbage, causing raw material waste. SUMMARY
[0004] Therefore, the tobacco leaf sorting and impurity removing platform solves the problem of dust generation during cleaning of the tobacco leaf sorting table surface.
[0005] The tobacco leaf sorting and impurity removing platform includes several workbenches and a conveyor belt. The workbenches are arranged along the conveyor belt transmission direction. The workbenches are provided with a grid surface sorting area. The grid surface sorting area is provided with a collection cavity at the bottom. The collection cavity is provided with a sieve drawer that can slide relative to the workbench. The bottom of the collection cavity is provided with a collection port for communication with an external negative pressure dust collection pipeline.
[0006] Optionally, the grid aperture of the grid surface sorting area is larger than the sieve aperture of the sieve drawer, and the grid aperture and the sieve aperture of the grid surface sorting area and the sieve drawer are both larger than the flow area of the negative pressure dust collection pipeline. The impurities larger than the grid aperture of the grid surface sorting area are retained on the grid surface sorting area, the impurities and tobacco leaves larger than the sieve aperture of the sieve drawer are retained on the sieve drawer, and the remaining tobacco and dust fall into the collection port below the sieve drawer, achieving multi-stage sorting of impurities and tobacco leaves. By adjusting the flow area, the dust suction power of the grid surface sorting area is reduced to prevent tobacco leaves from being adsorbed on the table surface.
[0007] Optionally, the grid sorting area includes weft rods and connecting rods connecting the weft rods. The weft rods are arranged in parallel at intervals, and the height of the weft rods is higher than the height of the connecting rods. Since the weft rods are the tallest, and the weft rods that contact the tobacco leaves are arranged in parallel, the tobacco leaves placed in the grid sorting area can be easily moved to the guide plate by hand, conforming to the ergonomic arm swing action and saving physical strength to the greatest extent.
[0008] Optionally, one end of the workbench is provided with an inclined guide plate, which is used to slide the sorted tobacco leaves onto the conveyor belt. The inclined guide plate allows the sorted tobacco leaves to slide onto the conveyor belt under their own weight, saving manpower.
[0009] Optionally, the screen drawer is slidably connected to the worktable, and the screen drawer includes a screen base plate and a baffle, the baffle being provided with a handle. The screen drawer is used to collect broken tobacco leaves and small pieces of debris, while simultaneously separating tobacco dust and soot.
[0010] Optionally, the worktable is equipped with support legs at its bottom, and the bottom of the support legs is equipped with casters with brakes. The casters facilitate the movement of the worktable.
[0011] Optionally, the workbench is equipped with multiple collection boxes on its side. The collection boxes are used to collect large debris or other recycled materials such as fallen leaves.
[0012] The beneficial effects of this utility model are:
[0013] Compared to conventional sorting tables, this system achieves separation of debris through a two-stage process: mesh and screen. Larger and smaller debris are retained in the mesh sorting area and screen drawer, respectively, facilitating graded and classified collection. The remaining, smaller debris, which is difficult to clean, is directly sucked away by the negative pressure dust collection pipe, reducing the difficulty of debris cleaning and collection. Simultaneously, the fumes generated during sorting are also sucked away by the negative pressure dust collection pipe, protecting workers' respiratory systems. Broken tobacco leaves can be recycled in the screen drawer for reuse, conserving raw tobacco materials. Attached Figure Description

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.
[0020] like Figures 1-3 As shown, this utility model discloses a tobacco leaf sorting and impurity removal platform, comprising several workbenches 1 and a conveyor belt. The workbenches 1 are arranged at intervals along the conveyor belt direction. Each workbench 1 has a grid-surface sorting area 11, and a collection chamber 12 is provided at the bottom of the grid-surface sorting area 11. The collection chamber 12 contains a sieve tray 13 that can be slidably opened relative to the workbench 1. The bottom of the collection chamber 12 has a collection port 14 for connecting to an external negative pressure dust collection pipeline. The external negative pressure dust collection pipeline is the existing negative pressure dust collection pipeline in the cigarette production workshop, including a negative pressure fan, a filter collection device, and pipelines laid to each workshop.
[0021] In this embodiment, the mesh aperture of the grid sorting area 11 is larger than the mesh aperture of the screen tray 13, and the flow area of both the mesh aperture of the grid sorting area 11 and the screen aperture of the screen tray 13 is larger than the flow area of the negative pressure dust collection pipe. During the tobacco leaf sorting process, debris larger than the mesh aperture of the grid sorting area 11 remains on the grid sorting area 11, while small pieces of debris and broken tobacco leaves larger than the screen aperture of the screen tray 13 remain on the screen tray 13. The remaining tobacco dust and soot fall into the collection port below the screen tray 13, thus achieving multi-stage sorting of debris and tobacco leaves.
[0022] In this embodiment, by setting the flow area, the flow areas of the negative pressure dust collection pipe, the screen drawer 13 and the grid surface sorting area are gradually increased from small to large, which weakens the negative pressure wind force of the grid surface sorting area 11, so that the negative pressure wind force of the grid surface sorting area 11 can only be used to absorb a small amount of dust, thus avoiding the situation where tobacco leaves are adsorbed on the table. Meanwhile, the screen holes of the screen drawer 13 maintain a large wind force to adsorb smoke droplets and dust.
[0023] In this embodiment, an inclined guide plate 15 is provided at one end of the workbench 1 near the conveyor belt. The guide plate 15 is used to slide the sorted tobacco leaves onto the conveyor belt.
[0024] In this embodiment, the grid sorting area 11 includes weft rods 111 and connecting rods 112 connecting the weft rods 111. The weft rods 111 are arranged in parallel at intervals, and the height of the weft rods 111 is higher than the height of the connecting rods 112, so that only the parallel weft rods 111 are in contact with the tobacco leaves. This allows the operator to easily slide the sorted tobacco leaves along the weft rods 111 to the guide plate by hand, thus saving physical effort. It is understood that the weft rods 111 can be chamfered or rounded to avoid cutting the operator's fingers during the sorting process.
[0025] In this embodiment, the screen drawer 13 is slidably connected to the workbench 1. The screen drawer 13 includes a screen base plate and a baffle plate, with a handle on the baffle plate. The contents of the screen drawer 13 can be observed through the mesh holes of the mesh sorting area 11. When cleaning is required, the screen drawer 13 can be pulled out by the handle to clean the small pieces of debris and broken tobacco leaves collected inside. The bottom of the workbench 1 is equipped with support legs, and the bottom of the support legs is equipped with casters with brake devices. Three collection frames are detachably provided on the side of the workbench 1 for collecting large pieces of debris, discarded leaves, worthless tobacco leaves, and tobacco stems, respectively. It should be understood that the support legs, casters, brake devices, collection frames, etc., are all existing technologies, and their specific structures and principles will not be described in detail.
[0026] The working principle of this utility model is as follows:
[0027] When using the sorting and impurity removal platform of this utility information, the tobacco leaves to be sorted (bundled tobacco leaves) are placed on the grid sorting area 11 for sorting. The sorted tobacco leaves can be easily moved by hand along the weft bar 111 to the guide plate. The tobacco leaves can slide down the conveyor belt by their own weight and be sent to the downstream process. The large pieces of debris, fallen leaves, worthless tobacco leaves and tobacco stems that are sorted out are placed into the collection bins respectively.
[0028] During this process, the broken tobacco leaves, small pieces of debris mixed in with the tobacco leaves, as well as the broken tobacco leaves generated during the sorting process, fall into the screen tray 13 through the mesh holes of the mesh sorting area 11. Debris larger than the mesh holes of the mesh sorting area 11 remains on the mesh sorting area 11, and debris and tobacco leaves larger than the screen holes of the screen tray 13 remain on the screen tray 13. Only periodic cleaning and separation of the screen tray 13 is required. The remaining tobacco dust and smoke fall into the collection port 14 below the screen tray 13 and are directly sucked away by the negative pressure dust collection pipe, realizing multi-stage sorting of debris and tobacco leaves.
[0029] Compared to conventional sorting platforms, the sorting and impurity removal platform of this invention achieves separation of impurities through a two-stage process: mesh holes and screen holes. Larger and smaller pieces of impurities are retained in the mesh sorting area 22 and screen drawer 24, respectively, for easy collection. The remaining small impurities, which are difficult to clean, are directly sucked away by the negative pressure dust collection pipe, reducing the difficulty of cleaning and collecting impurities. Simultaneously, the dust generated during sorting is also sucked away by the negative pressure dust collection pipe, protecting the workers' respiratory system from damage. Broken tobacco leaves can be recycled in the screen drawer for reuse, conserving tobacco raw materials.
[0030] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
