Description

Technical Field

[0001] This utility model relates to the field of tobacco leaf sampling technology, specifically to a tobacco leaf perforation sampler. Background Technology

[0002] Tobacco leaf sampling is a crucial and fundamental technical task in the tobacco industry chain. Its scientific rigor and standardization directly affect the accuracy and reliability of subsequent quality evaluation, chemical analysis, and industrial applications. To reduce bias and improve representativeness, random sampling or systematic periodic sampling methods should be used when sampling tobacco leaves to ensure that each unit has an equal opportunity to be sampled. Each sample should also be of equal quantity, typically containing 10-15 tobacco leaves, while taking into account a reasonable proportion of large, medium, and small leaves to avoid over-representation of any particular type of leaf and distortion of the overall characteristics. At the same time, tobacco leaves affected by pesticides, fertilizers, or other non-experimental factors should be excluded during sampling to ensure sample purity and reflect the true treatment effect.

[0003] Existing tobacco leaf perforation samplers often only have the function of perforating and cutting tobacco leaves. After cutting, the tobacco leaf samples often need to be manually sorted and stored separately. However, the number of tobacco leaf samples is large, and collecting them one by one is time-consuming and troublesome. This increases the workload of tobacco leaf sampling, reduces the efficiency of tobacco leaf sampling, and may cause contamination of tobacco leaf samples during the collection and sorting process, affecting the purity of tobacco leaf samples and the accuracy and reliability of subsequent quality evaluation, chemical analysis and industrial applications. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a tobacco leaf perforation sampler that can continuously perforate and sample tobacco leaves, and automatically seal and store the tobacco leaf samples independently to prevent contamination.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A tobacco leaf perforation sampler, comprising:

[0007] The clamping module includes a fixed plate and a movable plate. A receiving module is provided on the fixed plate, and a feeding module is provided on the movable plate corresponding to the receiving module. A pressing and discharging module is provided at the top of the feeding module, and a limit braking module is provided at the bottom.

[0008] The sampling unit is slidably set in the ammunition feeding module, and multiple sampling units are set in the ammunition feeding module. By pressing down the ammunition feeding module, the lowest sampling unit is arranged in the limiting braking module. After the fixed plate and the moving plate are clamped together, the lowest sampling unit is transferred to the receiving module.

[0009] The sampling unit includes a perforated cylindrical shell, with an open bottom and an annular blade, and a connector at the top that engages with the annular blade.

[0010] As an improvement, the top of the perforated round shell is provided with an annular groove corresponding to the annular blade, and the outer wall is provided with wedge-shaped ratchet and gripping slot.

A receiving groove is provided on the inner wall corresponding to the wedge-shaped ratchet, and a receiving ratchet is provided in the receiving groove. The ratchet teeth of the receiving ratchet are elastic structures. The wedge-shaped ratchet teeth are slidably disposed in the receiving groove and are locked in one direction after engaging with the receiving ratchet, preventing them from sliding upward.

[0012] As an improvement, the receiving module is provided with a pair of gripping pawls on the top corresponding to the gripping slot. The gripping pawls are elastic structures with an inclined top surface, and after being inserted and engaged with the gripping slot, they pull the perforated round shell.

[0013] As an improvement, the receiving module is provided with an unloading module, which includes an unloading slider. An unloading groove is vertically provided on one side of the receiving tube. The unloading slider is slidably disposed in the unloading groove. An unloading pawl that engages with the gripping slot is provided on one side, and a sliding key is provided on the other side. The unloading pawl is an elastic structure with an inclined top surface.

[0014] As an improvement, the ammunition feeding module includes an ammunition feeding tube, the bottom of which is fixed to a movable plate. An ammunition feeding groove is provided on the inner wall corresponding to the wedge-shaped ratchet teeth, and an ammunition feeding spur is provided in the ammunition feeding groove. The ratchet teeth of the ammunition feeding spur are elastic structures. The wedge-shaped ratchet teeth are slidably disposed in the ammunition feeding groove and are locked in one direction after engaging with the ammunition feeding spur, preventing them from sliding upwards.

[0015] As an improvement, the limiting braking module includes a limiting sleeve fixed to the bottom of the moving plate. Limiting tubes and limiting claws are respectively provided on both sides of the limiting sleeve. One end of the limiting claw is slidably disposed in the corresponding limiting tube and a limiting spring is provided between the limiting tube and the limiting tube. After the top of the other end abuts against the bottom plane of the wedge-shaped ratchet, the corresponding perforated round shell is limited in the limiting sleeve and cannot move downward.

[0016] As an improvement, a pressing ring is slidably provided at the bottom of the limiting sleeve, and a pair of pressing blocks and a wedge-shaped top block are mirror-arranged on the top of the pressing ring. A pressing tube is provided inside the limiting sleeve, and the pressing blocks are slidably arranged inside the pressing tube. A pressing spring is provided between the top of the pressing tube and the pressing block. The bottom of the limiting claw is provided with an inclined surface, which abuts against the inclined surface of the top of the wedge-shaped top block. After the pressing ring is pressed into the limiting sleeve, the two limiting claws move in opposite directions and separate from the wedge-shaped ratchet, so that the corresponding perforated round shell leaves the limiting sleeve.

[0017] As an improvement, the pressing and dispensing module includes a spring tube, which is detachably installed on the top of the feeding module. A knob is rotatably installed on the top, and a lifting plate is slidably installed inside. The knob shaft is connected to a screw, and the lifting plate is threaded onto the screw. A pressing spring is installed at the bottom, and a pressure plate is horizontally installed at the other end of the pressing spring.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] A tobacco leaf perforation sampler, combined with an attached Figure 1 Appendix Figure 2 Appendix Figure 3 As shown, the device includes a clamping module 1, which includes a housing 13. A parallel clamping structure 15 is provided inside the housing 13. A handle 14 is provided at the bottom. A fixed plate 11 and a movable plate 12 are provided on one side. The fixed plate 11 is connected to the housing 13. The movable plate 12 is arranged parallel to the fixed plate 11 directly above it through the parallel clamping structure 15. A receiving module 4 is erected on the fixed plate 11. A feeding module 3 is erected on the movable plate 12 corresponding to the receiving module 4. A pressing and discharging module 5 is provided at the top of the feeding module 3. A limit braking module 6 is provided at the bottom. Multiple sampling units 2 are slidably arranged up and down inside the feeding module 3 and the receiving module 4. A discharging module 7 is provided on the receiving module 4.

[0035] In the above description, multiple sampling units 2 are placed into the ammunition supply module 3. After the ammunition discharge module 5 is pressed down, the lowest sampling unit 2 is arranged in the limiting braking module 6. The tobacco leaves are placed between the fixed plate 11 and the moving plate 12. After the fixed plate 11 and the moving plate 12 are clamped by the parallel clamping structure 15, the lowest sampling unit 2 punches holes in the tobacco leaves to take samples and transfers them into the receiving module 4. After multiple samplings are performed to ensure that all the sampling units 2 in the ammunition supply module 3 enter the receiving module 4, the sampling units 2 in the receiving module 4 are taken out simultaneously by the ammunition unloading module 7 and transferred for storage.

[0036] Combined with appendix Figure 2 Appendix Figure 4 Appendix Figure 8As shown, the sampling unit 2 includes a perforated circular shell 21. The bottom of the perforated circular shell 21 is open and has an annular blade 22. The top of the perforated circular shell 21 has a connector 23 that is inserted and mated with the annular blade 22. The top of the perforated circular shell 21 has an annular groove 24 corresponding to the annular blade 22. The outer wall has a wedge-shaped ratchet 25 and a gripping slot 26. The gripping slot 26 and the wedge-shaped ratchet 25 are arranged alternately and symmetrically in pairs. The gripping slot 26 is a triangular groove with a flat bottom. The wedge-shaped ratchet 25 has a bevel and a flat bottom and a flat top.

[0037] As described above, after the fixed plate 11 and the moving plate 12 are clamped together, the perforated circular shell 21 arranged in the limiting braking module 6 is pressed down along with the limiting braking module 6, and the tobacco leaf is perforated and cut into a circle by the annular blade 22 to obtain a circular tobacco leaf sample. After the annular blade 22 is pressed down, it is inserted into the connector 23 of the perforated circular shell 21 below and inserted into the corresponding annular blade groove 24, so that the two perforated circular shells 21 are connected together, and the tobacco leaf sample is stored in the sealed cavity formed by the two perforated circular shells 21 to prevent contamination from contact with the outside world.

[0038] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 6 As shown, the ammunition supply module 3 includes an ammunition supply tube 31, the bottom of which is fixed to the movable plate 12. Multiple positioning grooves are provided on its top, and an ammunition supply groove 32 is provided on its inner wall corresponding to the wedge-shaped ratchet 25. An ammunition supply spur 33 is provided within the ammunition supply groove 32. The ratchet teeth of the ammunition supply spur 33 are elastic structures. The wedge-shaped ratchet 25 is slidably disposed within the ammunition supply groove 32 and engages with the ammunition supply spur 33 (as shown in the attached diagram). Figure 3 Appendix Figure 6 As shown, its ratchet is a one-way ratchet and is connected to the main body of the feed ratchet 33 via an elastic connecting rod.

[0039] As described above, when the perforated shell 21 is pushed downward, the elastic connecting rod bends outward, causing the ratchet to move outward and separate from the wedge-shaped ratchet 25, allowing the perforated shell 21 to slide downward. When the perforated shell 21 is pushed upward, the top plane of the wedge-shaped ratchet 25 engages with the feed ratchet 33, and the elastic connecting rod does not bend outward, locking the perforated shell 21 so that it cannot slide upward. The downward-pressing feed module 5 provides a downward thrust to the perforated shell 21, and after being limited by the limiting braking module 6, the perforated shell 21 slides downward so that the lowest sampling unit 2 is arranged in the limiting braking module 6.

[0040] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 5 Appendix Figure 6As shown, the spring tube 5 includes a spring tube 51, which is arranged vertically. The bottom of the spring tube 51 is provided with a protrusion that is inserted into the positioning groove at the top of the feeding tube 31. A connecting cover 52 is rotatably provided, and a knob 53 is rotatably provided at the top. A lifting plate 55 is slidably provided inside. The knob 53 is connected to a screw 54. The lifting plate 55 is threaded onto the screw 54. A pressing spring 56 is provided at the bottom. A pressure plate 57 is horizontally provided at the other end of the pressing spring 56. After the positioning groove is inserted into the corresponding protrusion, the connecting cover 52 is threaded onto the top of the feeding module 3, and the pressure plate 57 abuts against the top of the uppermost sampling unit 2.

[0041] In the above description, after multiple sampling units 2 are inserted into the ammunition supply tube 31 from the top, the positioning groove is inserted into the corresponding protrusion (to prevent the spring tube 51 from rotating), and the connecting cover 52 is rotated so that the spring tube 51 is detachably set on the top of the ammunition supply module 3. The knob 53 is rotated to rotate the screw 54, and the lifting plate 55 moves up and down along the spring tube 51. The pressure plate 57 abuts against the top of the uppermost sampling unit 2, and after being connected to the lifting plate 55 through the downward pressure spring 56, it presses down on the lower sampling unit 2. During the sampling process, the position of the lifting plate 55 can be adjusted by rotating the knob 53, thereby adjusting the pressure of the downward pressure to ensure that the sampling unit 2 slides down, and the lowermost sampling unit 2 is arranged in the limit braking module 6.

[0042] Combined with appendix Figure 3 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 As shown, the limiting braking module 6 includes a limiting sleeve 61 fixed to the bottom of the moving plate 12. Limiting tubes 62 and limiting claws 63 are respectively provided on both sides of the limiting sleeve 61. One end of the limiting claw 63 is slidably disposed in the corresponding limiting tube 62, and a limiting spring 64 is provided between the limiting claw 63 and the limiting tube 62. The top of the other end abuts against the bottom plane of the wedge-shaped ratchet 25. A pressing ring 66 is slidably disposed up and down at the bottom of the limiting sleeve 61. A pair of pressing blocks 67 and a wedge-shaped top block 65 are mirrored on the top of the pressing ring 66. A pressing tube 68 is disposed inside the limiting sleeve 61. The pressing blocks 67 are slidably disposed in the pressing tube 68, and a pressing spring 69 is provided between the top of the pressing ring 67 and the pressing tube 68. The bottom of the limiting claw 63 is provided with an inclined surface, which abuts against the inclined surface of the top of the wedge-shaped top block 65. After the pressing ring 66 is pressed into the limiting sleeve 61, the two limiting claws 63 move in opposite directions and separate from the wedge-shaped ratchet 25.

[0043] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 8 Appendix Figure 11As shown, the receiving module 4 includes a receiving tube 41. A cartridge unloading groove 45 is vertically arranged on one side of the receiving tube 41. The top is fixed to the fixing plate 11, and a flip cover 44 is hinged to the bottom. A receiving groove 42 is provided on the inner wall corresponding to the wedge-shaped ratchet 25, and a receiving ratchet 43 is provided inside the receiving groove 42. The ratchet teeth of the receiving ratchet 43 are elastic structures. The wedge-shaped ratchet 25 is slidably disposed within the receiving groove 42 and engages with the receiving ratchet 43 (as shown in the attached diagram). Figure 2 Appendix Figure 8 As shown, it is the same as the feed ratchet 33, and the ratchet teeth are unidirectional ratchet teeth, and are connected to the main body of the receiving ratchet 43 through an elastic connecting rod. A pair of gripping pawls 46 are provided on the top of the receiving module 4 corresponding to the gripping slot 26. The gripping pawls 46 are elastic structures with an inclined top surface, and are inserted into the gripping slot 26.

[0044] In the above description, after the fixed plate 11 and the moving plate 12 are clamped together, the perforated circular shell 21 punches and cuts the tobacco leaf into a circle through the annular blade 22 and connects with the lower perforated circular shell 21. At the same time, the pressing ring 66 is pressed into the limiting sleeve 61, and the two limiting claws 63 are pushed outward by the wedge-shaped top blocks 65 on both sides. The two limiting claws 63 are separated from the corresponding wedge-shaped ratchet 25 respectively, and under the push of the pressing and ejecting module 5, they abut against the lower perforated circular shell 21 (set in the receiving module 4). During the process, the uppermost perforated circular shell 21 of the receiving module 4 is pressed down, so that the gripping claw 46 is inserted into the limiting sleeve 61, and after the top inclined surface abuts against the bottom of the perforated circular shell 21, the two gripping claws 46 move outward. The pawl 46 bends outward and slides on the side wall of the perforated round shell 21 until it aligns with the gripping slot 26. Then, it is inserted into the corresponding gripping slot 26. The bottom of the gripping pawl 46 abuts against the bottom surface of the gripping slot 26, preventing the perforated round shell 21 from moving upward. After the fixed plate 11 and the moving plate 12 separate, the pressing ring 66 and the limiting pawl 63 are reset respectively. The perforated round shell 21 in the limiting braking module 6 is pulled down by the gripping pawl 46 and transferred to the receiving module 4, connecting with the original uppermost perforated round shell 21 in the receiving module 4. The perforated round shell 21 in the feeding module 3 is pushed down by the pressing ejection module 5 and added to the limiting braking module 6.

[0045] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 8 Appendix Figure 11 As shown, the receiving module 4 is provided with an unloading module 7. The unloading module 7 includes an unloading slider 71, which is slidably disposed in the unloading groove 45. One side is provided with an unloading pawl 72 that engages with the gripping slot 26, and the other side is provided with a sliding key 73. The unloading pawl 72 is an elastic structure with an inclined top surface.

[0046] In the above description, the perforated round shell 21 inside the receiving module 4 is locked by the receiving ratchet 43 and cannot move upward. When the sliding key 73 is moved upward, the top slope of the ejector pawl 72 abuts against the bottom of each perforated round shell 21 and the top slope of the gripping slot 26, and then bends outward to avoid it. When the sliding key 73 is moved downward, the bottom of the ejector pawl 72 abuts against the top of the perforated round shell 21 or the bottom surface of the gripping slot 26, and engages with the perforated round shell 21, and drives the perforated round shell 21 to move downward. After opening the flip cover 44, the sliding key 73 is moved downward to make the perforated round shell 21 inside the receiving module 4 leave the bottom of the receiving tube 41 (take care to prevent the perforated round shell 21 from dispersing). After the sliding key 73 moves to the top, the ejector pawl 72 is embedded in the bottom of the gripping pawl 46.

[0047] Combined with appendix Figure 1 Appendix Figure 9 Appendix Figure 10 As shown, the parallel clamping structure 15 includes a lifting arm 151, one end of which is connected to the moving plate 12, and the other end is slidably disposed inside the housing 13. A vertical rack 152 is vertically disposed, and a horizontal rack 153 is slidably disposed inside the housing 13. The horizontal rack 153 is horizontally disposed, and a return spring 156 is disposed between one end of the rack and the housing 13. A trigger 155 is disposed at the bottom and passes through the housing 13 to be disposed on one side of the handle 14. A transmission gear 154 is rotatably disposed inside the housing 13, and the vertical rack 152 and the horizontal rack 153 respectively mesh with the transmission gear 154.

[0048] As described above, after pulling the trigger 155, the horizontal rack 153 slides and drives the vertical rack 152 to move downward through the transmission gear 154, so that the lifting arm 151 drives the moving plate 12 to press down on the fixed plate 11, and the fixed plate 11 and the moving plate 12 are clamped together. After releasing the trigger 155, the horizontal rack 153 moves in the opposite direction through the return spring 156, and drives the moving plate 12 to move upward and reset through the lifting arm 151, separating from the fixed plate 11.

[0049] In this embodiment, after multiple sampling units 2 are inserted into the ammunition supply tube 31 from the top, the positioning groove is engaged with the corresponding protrusion (to prevent the spring tube 51 from rotating), and the connecting cover 52 is rotated so that the spring tube 51 is detachably mounted on the top of the ammunition supply module 3. The knob 53 is rotated to rotate the screw 54, and the lifting plate 55 moves up and down along the spring tube 51. The pressure plate 57 presses down on the lower perforated shell 21, so that the lowermost perforated shell 21 is positioned at the limit. Inside the braking module 6, tobacco leaves are placed between the fixed plate 11 and the moving plate 12. Pulling the trigger 155 causes the fixed plate 11 and the moving plate 12 to clamp together via the parallel clamping structure 15. The perforated circular shell 21 uses the annular blade 22 to perforate and cut the tobacco leaves into a circle, connecting to the lower perforated circular shell 21. Simultaneously, the pressing ring 66 is pressed into the limiting sleeve 61, and the wedge-shaped top blocks 65 on both sides push the limiting claws 63 outwards. The two limiting claws 63 separate from their corresponding wedge-shaped ratchet teeth 25. Under the push of the downward ejection module 5, it abuts against the lower perforated circular shell 21 (set inside the receiving module 4). During the process, the uppermost perforated circular shell 21 of the receiving module 4 is pressed down, causing the gripping pawl 46 to pass through the limiting sleeve 61 and insert into the corresponding gripping slot 26, engaging with the corresponding perforated circular shell 21. When the trigger 155 is released, the fixed plate 11 and the moving plate 12 separate. The gripping pawl 46 pulls down the perforated circular shell 21 inside the limiting braking module 6, and the perforated circular shell 21 is transferred to the receiving module. On group 4, it is connected to the perforated round shell 21 at the top of the original receiving module 4, and the perforated round shell 21 in the ammunition supply module 3 is pushed down by the pressing ammunition delivery module 5 to supplement the limit braking module 6; after multiple samplings are performed to ensure that all the sampling units 2 in the ammunition supply module 3 enter the receiving module 4, the flip cover 44 is opened, and the sliding key 73 is moved down to make the perforated round shell 21 in the receiving module 4 leave from the bottom of the receiving tube 41 (take care to prevent the perforated round shell 21 from dispersing), and then it is collected, marked and transferred for storage.

[0050] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
