Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a finished tobacco leaf testing device. Background Technology

[0002] In the tobacco processing industry, after initial curing, grading, and purchasing, tobacco leaves typically undergo re-drying at tobacco re-drying plants. This process adjusts the moisture content of the leaves, improves their quality, cleans them, removes impurities, and enhances their storage stability. The purity of the finished tobacco leaves obtained after re-drying (referring to the absence or minimal presence of non-tobacco impurities such as hemp fibers, plastic flakes, metal shavings, and paper scraps—a fundamental requirement for food safety and process cleanliness) is a crucial indicator of product quality. It directly impacts subsequent cigarette processing efficiency, product quality, equipment safety, and even brand reputation.

[0003] Currently, the quality inspection of finished tobacco products, especially the inspection of purity, mainly relies on traditional manual visual inspection methods. In existing technology, inspectors usually use fixed light sources or handheld portable lighting equipment (such as flashlights) in a storage room to observe and judge each finished tobacco product individually.

[0004] However, a single fixed light source often has problems such as uneven illumination, insufficient brightness, or unidirectional light direction, which can easily lead to unclear observation of certain areas on the surface of the finished tobacco leaf or cause visual errors, thus affecting the reliability of the test results. When different inspectors use handheld lights for testing, it is difficult to keep the position, angle, and brightness of the light source consistent. This not only easily leads to inconsistent judgments on the appearance quality of the same tobacco leaf, but also makes it difficult to achieve uniformity in testing standards and repeatability of test results. Utility Model Content

[0005] The purpose of this invention is to provide a finished tobacco sheet testing device that not only ensures that the position, angle, and brightness of the light source remain consistent when different inspectors test finished tobacco sheets, thereby improving the uniformity of testing standards and the repeatability of test results, but also illuminates the surface of the finished tobacco sheets as much as possible to facilitate observation by inspectors, thus improving the reliability of test results.

In the unfolded state, at least some of the blades are rotated to have a non-zero angle between their axes and the first direction in order to adjust the illumination angle of the detection lamp.

[0011] Preferably, each blade includes a connecting portion and mounting portions respectively provided at both ends of the connecting portion. The two mounting portions are connected to the connecting portion at the same included angle and extend in opposite directions. Each connecting portion is rotatably connected to the bearing assembly. The mounting portion is used to install the detection lamp.

[0012] Preferably, in each blade, two mounting portions are arranged symmetrically with respect to the connecting portion.

[0013] Preferably, the mounting assembly further includes a rotating shaft, and each of the connecting parts is provided with a through rotating hole. One end of the rotating shaft passes through the rotating hole and is threadedly connected to the bearing assembly. The other end of the rotating shaft can be pressed against the side of the blade facing away from the bearing assembly to lock the blade.

[0014] Preferably, the connecting portions of all the blades are stacked, and the thickness of the connecting portion is greater than the thickness of the mounting portion.

[0015] Preferably, the load-bearing assembly includes a support frame and a load-bearing base, with each blade rotatably connected to the load-bearing base, and the load-bearing base rotatably connected to the support frame.

[0019] Preferably, the finished tobacco sheet detection device further includes a control component electrically connected to the detection lamp.

[0020] As a preferred embodiment, the finished tobacco sheet detection device further includes a protective cover, which is placed over the detection lamp.

[0021] The beneficial effects of this utility model are:

[0022] The finished tobacco leaf testing device provided by this utility model includes a support component and a mounting component. The mounting component includes at least two blades, each blade equipped with a detection lamp and rotatably connected to the support component. The mounting component has a retracted state where the axis of each blade is parallel to a first direction, and an unfolded state where the axis of at least some blades has a non-zero angle with the first direction.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 3 As shown, this utility model provides a finished tobacco sheet detection device, which includes a support component 1 and an installation component 2. The installation component 2 includes at least two blades 21, each blade 21 is equipped with a detection lamp 3, and each blade 21 is rotatably connected to the support component 1. The installation component 2 has a retracted state and an unfolded state. In the retracted state, the axis of each blade 21 is rotated to be parallel to a first direction. In the unfolded state, at least some of the blades 21 are rotated to have a non-zero angle between their axis and the first direction.

[0034] Before testing the finished tobacco sheets, switch the mounting assembly 2 from the retracted state to the unfolded state and turn on the detection lamp 3. Rotate the blade 21 according to the light from the detection lamp 3 to adjust the illumination angle of the detection lamp 3 until the light can illuminate the surface of the finished tobacco sheets. After the light adjustment is completed, the finished tobacco sheets are then tested. This not only ensures that the position, angle, and brightness of the light source are kept as consistent as possible when different inspectors test the finished tobacco sheets, improving the uniformity of the testing standards and the repeatability of the test results, but also illuminates the surface of the finished tobacco sheets as much as possible for inspectors to observe, thus improving the reliability of the test results.

[0035] For example, the detection lamp 3 can be an LED tube with adjustable color temperature. After installation, the axis of the lamp tube is parallel to the axis of the blade 21, and at least two lamp tubes are arranged parallel to each other on the surface of each blade 21 facing the finished tobacco sheet. This arrangement ensures that the surface of each blade 21 facing the finished tobacco sheet is covered by the detection lamp 3 as much as possible, thereby improving the illumination brightness and expanding the illumination range.

[0036] For example, the first direction can be adjusted according to the space and fixing requirements of the finished tobacco sheet detection device during storage or transportation, as long as it is convenient for storage or transportation. In this embodiment, the first direction is the length direction of the supporting component 1. In the stored state, all blades 21 can be close to the supporting component 1 to reduce space occupation, while in the unfolded state, all blades 21 rotate with reference to the supporting component 1, so that the operator can quickly determine the unfolding angle of the blades 21 to accurately position the illumination angle of the detection lamp 3.

[0037] Furthermore, each blade 21 includes a connecting portion 211 and mounting portions 212 respectively provided at both ends of the connecting portion 211. The two mounting portions 212 are connected to the connecting portion 211 at the same included angle and extend in opposite directions. Each connecting portion 211 is rotatably connected to the support assembly 1. The mounting portions 212 are used to mount the detection lamp 3. With this configuration, compared to the case of a conventional blade (one end of the conventional blade is rotatably connected to the support assembly 1), this embodiment, by providing mounting portions 212 capable of mounting the detection lamp 3 at both ends of the rotation center (i.e., the connecting portion 211) of the blade 21, with the two mounting portions 212 connected to the connecting portion 211 at the same included angle and extending in opposite directions, not only avoids the blade 21 occupying too much space when rotating, but also, with a fixed axial length of the blade 21, the axial length of the mounting portion 212 is longer, thereby enabling the mounting portion 212 to mount a larger area of ​​the detection lamp 3, improving the illumination intensity of the detection lamp 3 and expanding the illumination range of the detection lamp 3.

[0038] In the stowed state, the axis of the mounting part 212 of each blade 21 is rotated to be parallel to the first direction; in the unfolded state, at least some of the mounting parts 212 of the blades 21 are rotated to have a non-zero angle between the axis and the first direction. The user can rotate different blades 21 according to the light of the detection lamp 3 to adjust the illumination angle of the detection lamp 3 on different blades 21 until the light of all the detection lamps 3 can illuminate the surface of the finished tobacco sheet. After the light adjustment is completed, the finished tobacco sheet is then tested.

[0039] For example, the detection lamp 3 is disposed on the surface of the mounting portion 212 facing the finished tobacco sheet. In other embodiments, the detection lamp 3 may also be embedded inside the blade 21. Specifically, the mounting portion 212 is plate-shaped, with a V-shaped mounting groove formed recessed into its surface facing the finished tobacco sheet. The detection lamp 3 is snapped into the mounting groove, and the thickness of the detection lamp 3 is less than the depth of the mounting groove. This arrangement prevents the detection lamp 3 from being exposed above the blade 21, thus protecting the detection lamp 3.

[0040] Furthermore, the two mounting portions 212 of the blade 21 are arranged symmetrically with respect to the connecting portion 211, which can improve the irradiation intensity and irradiation range of the detection lamp 3 while ensuring the balance of the blade 21 during rotation.

[0041] Furthermore, the mounting assembly 2 also includes a rotating shaft, and each connecting part 211 is provided with a through rotating hole. One end of the rotating shaft passes through the rotating hole and is threadedly connected to the bearing assembly 1. The other end of the rotating shaft can press against the side of the blade 21 facing away from the bearing assembly 1 to lock the blade 21.

[0042] After adjusting the illumination angles of the detection lamps 3 on different blades 21 until the light from all the detection lamps 3 works together to illuminate the surface of the finished tobacco sheet, the rotating shaft is rotated. Since one end of the rotating shaft is threaded into the support component 1, the other end of the rotating shaft can be brought closer to the blade 21 until the other end of the rotating shaft can be pressed against the side of the connecting part 211 facing away from the support component 1, and the support component 1 is pressed against the connecting part 211. At this time, the pressing force on both sides of the blade 21 prevents the blade 21 from rotating around the rotating shaft, thus locking the angle of the blade 21. After locking, the finished tobacco sheet is inspected at this fixed blade 21 angle, which further improves the consistency of the position, angle, and brightness of the light source when different inspectors inspect the finished tobacco sheet, and achieves the uniformity of the inspection standard and the repeatability of the inspection results. In this way, the rotation and locking of the blade 21 can be controlled through a simple rotating structure, which effectively simplifies the manufacturing cost and reduces the difficulty of operation.

[0043] Furthermore, such as Figure 2 As shown, the connecting portions 211 of all blades 21 are stacked, and the thickness of the connecting portion 211 is greater than the thickness of the mounting portion 212. Because the thickness of the connecting portion 211 is greater than the thickness of the mounting portion 212, there is a certain gap between the mounting portions 212 of adjacent blades 21 in the stacking direction. This allows the detection lamp 3 mounted on the upper mounting portion 212 to be located within the gap without colliding with the lower mounting portion 212. Consequently, the lower blade 21 can rotate 360° relative to the upper blade 21, improving the flexibility of adjustment.

[0044] Furthermore, in order to achieve simultaneous locking and releasing of the blades 21 in the stacked state, one end of the rotating shaft is threadedly connected to the support component 1, and the other end of the rotating shaft can be pressed against the side of the outermost connecting part 211 facing away from the support component 1 to lock the blades 21. After adjusting the illumination angle of the detection lamps 3 on different blades 21 until the light from all the detection lamps 3 can illuminate the surface of the finished tobacco sheet, the rotating shaft is rotated. Since one end of the rotating shaft is threadedly connected to the support component 1, the other end of the rotating shaft can be moved closer to the blades 21 until the other end of the rotating shaft can be pressed against the side of the outermost connecting part 211 facing away from the support component 1. At this time, the pressing force on both sides of the connecting part 211 can prevent all the blades 21 from rotating around the rotating shaft, thereby locking the angle of the blades 21. After locking, the finished tobacco sheet is tested at the fixed angle of the blades 21.

[0045] In other embodiments, the blades 21 are not stacked, but are spaced apart on the support assembly 1 along a first direction. Alternatively, two blades 21 can be stacked to form a set of blades 21, with each set of blades 21 spaced apart on the support assembly 1 along the first direction.

[0046] Furthermore, the support assembly 1 includes a support frame 11 and a support base 12, with each blade 21 rotatably connected to the support base 12, and the support base 12 rotatably connected to the support frame 11. The rotation of the support base 12 relative to the support frame 11 can adjust the pitch angle of the entire mounting assembly 2 on it, thereby making all the blades 21 on the mounting assembly 2 face the worktable.

[0047] For example, two support frames 11 are arranged opposite each other, and the two ends of the bearing seat 12 are rotatably connected to one support frame 11, which improves the support stability of the support frame 11 on the bearing seat 12. For example, the height of the support frame 11 is adjustable, and the height of the bearing seat 12 can be controlled by adjusting the height of the support frame 11, thereby realizing the adjustment of the height of the detection lamp 3. Specifically, the support frame 11 includes a sleeve and a sliding rod. The sliding rod is connected to the bearing seat 12 and slidably disposed inside the sleeve. The sleeve is provided with multiple limiting holes along the axial direction. After the sliding rod is raised or lowered to a suitable position, the pin can pass through the limiting holes and abut against the sliding rod to fix the sliding rod, thereby realizing the adjustment of the height of the bearing seat 12 and the detection lamp 3.

[0048] For example, the support base 12 is rotatably connected to the upper end of two support frames 11, and there is a certain gap between the two support frames 11. Moving the support frame 11 can make the workbench located between the two support frames 11, so that the mounting component 2 is located on the upper side of the workbench, which makes it convenient for the staff to observe and adjust the blade 21 at the same time.

[0049] Furthermore, the first direction is the axial direction of the support seat 12. In the stored state, the axis of the mounting part 212 of each blade 21 is parallel to the axis of the support seat 12, so that the projected area of ​​all blades 21 in the plane perpendicular to the axis of the support seat 12 in the stored state is minimized, thereby reducing the volume occupied by the entire finished tobacco sheet detection device and facilitating storage.

[0050] Furthermore, a connecting rod 4 is fixedly provided at one end of the support base 12, and a mounting hole is provided at the upper end of the support frame 11. The connecting rod 4 can pass through and rotatably connect to the mounting hole, cooperating with the locking member 5 to lock the rotation of the support base 12. After the support base 12 rotates relative to the support frame 11 to a suitable position, so that all the blades 21 on the mounting assembly 2 face the worktable, the locking member 5 is rotated to lock the rotation of the support base 12 to fix the orientation of the blades 21. For example, as Figure 4 As shown, the locking element 5 can be a nut threadedly connected to the connecting rod 4. After the bearing seat 12 rotates to a suitable position relative to the support frame 11, rotating the nut causes the threaded engagement between the nut and the connecting rod 4 to move the nut toward the support frame 11. The nut presses against the support frame 11, causing the bearing seat 12, the support frame 11, and the nut to abut against each other in sequence. The abutting force between the bearing seat 12 and the support frame 11 can lock the rotation of the bearing seat 12. In other embodiments, the locking element 5 can also be a pawl fixedly connected to the support frame 11. After the bearing seat 12 rotates to a suitable position relative to the support frame 11, the pawl clamps the connecting rod 4 to lock the rotation of the bearing seat 12.

[0051] Furthermore, the finished tobacco sheet testing device also includes a movable base 6, with casters at the lower end of the movable base 6 and the upper end of the movable base 6 fixedly connected to the support component 1. The user can move the movable base 6 to move the support component 1 and the mounting component 2 closer to or away from the worktable, thereby causing the detection light 3 to move closer to or away from the worktable.

[0052] Furthermore, the movable seat 6 has an isosceles triangular structure, with the apex of the isosceles triangular movable seat 6 fixedly connected to the bottom of the support frame 11, and universal wheels corresponding to the two base corners of the isosceles triangular movable seat 6. The isosceles triangular structure of the movable seat 6 can improve its load-bearing capacity.

[0053] Furthermore, the movable seat 6 is also provided with a reinforcing rib 61, which is located inside the isosceles triangle and coincides with the axial direction of the support frame 11, further improving the load-bearing capacity of the movable seat 6.

[0054] Furthermore, the finished tobacco sheet detection device also includes a control component 7 electrically connected to the detection lamp 3. The control component 7 includes a brightness adjustment module, a color temperature adjustment module, and a timer switch module, which can control the brightness, color temperature, and switching time of the detection lamp 3.

[0055] For example, a control box is fixed to the side of the mobile base 6, and the control components 7 and the battery are placed in the control box, which can move with the mobile base 6, thus improving portability.

[0056] Furthermore, the finished tobacco sheet detection device also includes a protective cover, which is placed over the detection lamp 3 and can provide protection for the detection lamp 3.

[0057] For example, when the protective cover is placed between the detection lamp 3 and the blade 21, the protective cover is a semi-open structure. Specifically, the protective cover is "L"-shaped, and the outer side of the L-shaped protective cover is fixedly connected to the blade 21. The detection lamp 3 is placed inside the L-shaped protective cover, which can prevent the detection lamp 3 from being damaged when other objects fall. The inner side of the L-shaped protective cover is also covered with a reflective film. When the detection lamp 3 is placed between the protective cover and the blade 21, the detection lamp 3 is surrounded by the protective cover and the blade 21. The protective cover is made of transparent material, which can not only prevent the detection lamp 3 from being damaged when other objects fall, but also prevent dust and other contaminants from adhering to the surface of the detection lamp 3.

[0058] During operation, the movable seat 6 is moved to drive the mounting assembly 2 so that the detection lamp 3 is located on the upper side of the worktable. The locking piece 5 is loosened to release the carrier seat 12. The carrier seat 12 rotates relative to the support frame 11 to drive the mounting assembly 2 so that all blades 21 and the detection lamp 3 face the worktable. After rotating to the appropriate position, the locking piece 5 is tightened to lock the carrier seat 12. The mounting assembly 2 is unfolded and the detection lamp 3 is turned on. The blades 21 are rotated according to the light of the detection lamp 3 to adjust the illumination angle of the detection lamp 3 until the light can illuminate the surface of the finished tobacco sheet. After the light adjustment is completed, the finished tobacco sheet is then inspected.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
