Abstract
Description
Technical Field
[0001] This application belongs to the field of cigar leaf drying technology, specifically relating to a device for directing cigar tobacco leaves through a specific point. Background Technology
[0002] Cigars, as a special type of tobacco product, are characterized by their strong flavor, rich aroma, and low tar and nicotine content. In recent years, consumer demand has increased significantly, leading to a substantial rise in the demand for high-quality cigar tobacco leaves. After harvesting, cigar tobacco leaves need to be cured and processed. A key step before curing is threading the tobacco, which involves manually threading the leaves through the main vein 15mm-20mm from the base of the leaf stalk, alternating between two leaves, with the distance between two leaves in a group approximately 20mm. Multiple groups of leaves are then hung equidistantly and back-to-back on both sides of the tobacco stem, with 40-50 groups threaded per stem. After threading, the leaves are moved to the curing rack in the drying room for processing. Currently, various mechanized or semi-mechanized threading devices have been developed to address the limitations of manual threading. However, existing threading devices have poor accuracy, resulting in uneven distribution of tobacco leaves and affecting the quality of curing. Utility Model Content
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0004] In view of this, according to an embodiment of this application, a cigar tobacco leaf fixed-point tobacco threading device is proposed, comprising:
[0005] A needle-type cigarette clip, comprising positioning pins, which are arranged at equal intervals along the length of the needle-type cigarette clip.
[0006] The grooved tobacco clip is arranged parallel to the needle-type tobacco clip. The grooved tobacco clip includes a limiting groove that extends through the grooved tobacco clip along its width direction. The limiting groove positions the tobacco leaf in the width direction at the base of the leaf petiole.
[0007] The limiting grooves are arranged at equal intervals along the length of the grooved tobacco clip. The limiting grooves correspond one-to-one with the positioning pins. The tobacco leaves in the limiting grooves are fixed by inserting the positioning pins into the limiting grooves.
[0008] In one feasible implementation, a grooved cigarette clip is arranged directly below the needle-type cigarette clip, and a limiting groove is formed on the top surface of the grooved cigarette clip to support the base of the leaf stalk through the bottom of the limiting groove.
[0009] In one feasible implementation, the cigar tobacco leaf directing device further includes:
[0010] Control panel;
[0011] The positioning groove is set on the top surface of the operating table. The grooved cigarette clip is embedded in the positioning groove, and the bottom of the limiting groove is not lower than the top surface of the operating table.
[0012] In one feasible implementation, the bottom of the limiting groove and the top surface of the operating table are located in the same horizontal plane.
[0013] In one feasible implementation, the cigar tobacco leaf directing device further includes:
[0014] A baffle is arranged on the operating table in a direction parallel to the grooved tobacco clip. The baffle is located on one side of the grooved tobacco clip and positions the tobacco leaf along the length of the leaf stalk base.
[0015] In one feasible implementation, the cigar tobacco leaf directing device further includes:
[0016] The locking spring is elastic and is set on the end face of the grooved cigarette clip;
[0017] The bayonet is located on the end face of the pin-type cigarette clip. The bayonet corresponds to the locking spring. The locking spring is inserted into the bayonet to connect the grooved cigarette clip and the pin-type cigarette clip.
[0018] In one feasible implementation, the depth of the limiting groove is equal to the length of the positioning pin.
[0019] In one feasible implementation, the center point of the bottom of the limiting groove is located on the center line of the corresponding positioning pin.
[0020] In one feasible implementation, the width of the limiting groove gradually increases from the bottom of the limiting groove to the opening of the limiting groove.
[0021] In one feasible implementation, the width of the bottom of the limiting groove is 8mm to 12mm.
[0022] The cigar tobacco leaf fixed-point tobacco feeding device of this application has the following advantages compared with the prior art:
[0023] The cigar tobacco leaf fixed-point feeding device provided in this application embodiment includes a needle-type tobacco clip and a grooved tobacco clip. The grooved tobacco clip has multiple limiting grooves evenly arranged on it, which are used to position the base of the leaf stalk in the width direction. The needle-type tobacco clip has multiple positioning pins evenly arranged on it, and the positioning pins correspond one-to-one with the limiting grooves. By bringing the needle-type tobacco clip and the grooved tobacco clip closer together, the positioning pins are embedded into the corresponding limiting grooves. Thus, the tobacco leaves placed in the limiting grooves are fed into each positioning pin at the same time, reducing labor costs. While improving the feeding efficiency, it also ensures that the spacing of the tobacco leaves after feeding is consistent, which helps to improve the quality of tobacco leaf drying.

[0039] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0040] like Figure 1 and Figure 2 As shown in the embodiment of this application, a cigar tobacco leaf positioning device is proposed, comprising: a needle-type tobacco clip 11 and a grooved tobacco clip 12; the needle-type tobacco clip 11 includes positioning pins 110, which are arranged at equal intervals along the length direction of the needle-type tobacco clip 11; the grooved tobacco clip 12 is arranged parallel to the needle-type tobacco clip 11, and includes a limiting groove 120, which penetrates the grooved tobacco clip 12 along the width direction of the grooved tobacco clip 12, and positions the tobacco leaf in the width direction at the base of the leaf stalk; the limiting grooves 120 are arranged at equal intervals along the length direction of the grooved tobacco clip 12, and the limiting grooves 120 correspond one-to-one with the positioning pins 110, and the tobacco leaf in the limiting groove 120 is fixed by inserting the positioning pins 110 into the limiting groove 120.
[0041] The cigar tobacco leaf fixed-point tobacco threading device provided in this application embodiment includes a needle-type tobacco clip 11 and a grooved tobacco clip 12. The grooved tobacco clip 12 has a plurality of limiting grooves 120 evenly arranged on it. The limiting grooves 120 are used to position the base of the leaf stalk in the width direction. The needle-type tobacco clip 11 has a plurality of positioning pins 110 evenly arranged on it, and the positioning pins 110 correspond one-to-one with the limiting grooves 120. By the relative proximity of the needle-type tobacco clip 11 and the grooved tobacco clip 12, the positioning pins 110 are embedded into the corresponding limiting grooves 120. Thus, the tobacco leaves placed in the limiting grooves 120 are simultaneously threaded onto each positioning pin 110 at one time, reducing labor costs. While improving the tobacco threading efficiency, it also ensures that the spacing of the tobacco leaves after threading is consistent, which helps to improve the quality of tobacco leaf drying.
[0042] Furthermore, each limiting groove 120 contains two leaf stalks, and the two tobacco leaves in one limiting groove 120 are placed back to back so that when the tobacco is being dried, the two tobacco leaves are suspended back to back on the positioning pin 110.
[0043] As a preferred embodiment, the needle-type cigarette clip 11 has a total length of 1500mm and a width of 70mm. Starting from 150mm from the end of the needle-type cigarette clip 11, a positioning pin 110 is arranged at every 50mm interval, for a total of 25 positioning pins 110.
[0044] As a preferred embodiment, the grooved cigarette clip 12 has a total length of 1495mm and a width of 55mm. Starting from the end of the pin-type cigarette clip 11 at 147.5mm, a limiting groove 120 is provided every 50mm. The limiting groove 120 corresponds one-to-one with the positioning pin 110.
[0045] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the grooved cigarette clip 12 is arranged directly below the needle-type cigarette clip 11, and the limiting groove 120 is formed on the top surface of the grooved cigarette clip 12 to support the base of the leaf stalk through the bottom of the limiting groove 120.
[0046] In this technical solution, the grooved tobacco clip 12 is arranged parallel to the bottom of the needle-type tobacco clip 11. The tobacco leaves fall naturally into the limiting groove 120, and the base of the leaf stalk automatically fits into the bottom of the groove. The grooved tobacco clip 12 supports the base of the leaf stalk. When inserting the tobacco, the grooved tobacco clip 12 remains stationary to prevent displacement of the tobacco leaves after positioning. By moving the needle-type tobacco clip 11 downward, the positioning pin 110 is inserted into the corresponding limiting groove 120 to fix the base of the tobacco leaf stalk, thereby fixing the tobacco insertion distance.
[0047] In some examples, the needle-type cigarette clip 11 can be raised and lowered manually, or it can be connected to a lifting device to achieve automatic raising and lowering.
[0048] As a preferred option, the needle-type cigarette clip 11 is detachably connected to the lifting device. The lifting device drives the needle-type cigarette clip 11 to descend, gradually approaching the grooved cigarette clip 12, until the positioning pin 110 is fully embedded in the limiting groove 120. The connection point between the needle-type cigarette clip 11 and the lifting device is fixed, which helps to improve the alignment accuracy between the needle-type cigarette clip 11 and the grooved cigarette clip 12.
[0049] like Figures 3 to 6 As shown, in one feasible embodiment, the cigar tobacco leaf fixed-point tobacco feeding device further includes: an operating table 13 and a positioning groove 14; the positioning groove 14 is disposed on the top surface of the operating table 13, the grooved tobacco clip 12 is embedded in the positioning groove 14, and the bottom of the limiting groove 120 is not lower than the top surface of the operating table 13.
[0050] In this technical solution, the grooved cigarette clip 12 is placed on the operating table 13, and the grooved cigarette clip 12 is embedded in the positioning groove 14 to complete the horizontal calibration. The positioning groove 14 positions the grooved cigarette clip 12, and the operating table 13 supports the grooved cigarette clip 12. By making the limiting groove 120 completely exposed outside the operating table 13, the limiting groove 120 ensures the limiting effect of the limiting groove 120 on the base of the leaf petiole. The base of the leaf petiole of the tobacco leaf is supported by the bottom surface of the limiting groove 120, and the leaf blade is supported by the operating table 13. This avoids the leaf petiole from being suspended and bent when the tobacco leaf is placed, reduces the risk of leaf vein damage, and thus helps to improve the qualification rate of the tobacco leaf after the needle-type cigarette clip 11 is inserted.
[0051] As a preferred embodiment, the tabletop 13 has a length of 1800mm, a width of 1000mm, and a height of 800mm; the positioning groove 14 has a length of 1500mm, a width of 25mm, and a depth of 15mm to accommodate the grooved cigarette clip 12.
[0052] like Figure 4 and Figure 5 As shown, in one feasible implementation, the bottom of the limiting groove 120 and the top surface of the operating table 13 are located in the same plane.
[0053] In this technical solution, the bottom surface of the limiting groove 120 and the table surface of the operating table 13 are located in the same horizontal plane so that the tobacco leaves can be placed horizontally, avoiding the tobacco leaves from slipping due to the height difference between the bottom surface of the limiting groove 120 and the table surface of the operating table 13, thereby ensuring that the base of the leaf stalk can be stably embedded in the limiting groove 120 without displacement before the needle-type tobacco clip 11 inserts the tobacco.
[0054] like Figures 3 to 6 As shown, in one feasible embodiment, the cigar tobacco leaf positioning device further includes: a baffle 15; the baffle 15 is arranged on the operating table 13 in a direction parallel to the grooved tobacco clip 12, the baffle 15 is located on one side of the grooved tobacco clip 12, and the baffle 15 positions the tobacco leaf in the length direction of the leaf stalk base.
[0055] In this technical solution, the baffle 15 is located on one side of the grooved tobacco clip 12. By making the tobacco leaf stalk rest against the baffle 15, the base of the stalk is positioned in the length direction. There is no need to adjust the position of each tobacco leaf individually, and all the stalks in the grooved tobacco clip 12 can be quickly positioned.
[0056] As a preferred embodiment, the baffle 15 is arranged along the length of the operating table 13. The baffle 15 is 1800mm long and 50mm high. A 30mm gap is left between the positioning groove 14 and the baffle 15 to position the leaf stalk.
[0057] like Figure 7 and Figure 8 As shown, in one feasible embodiment, the cigar tobacco leaf fixed-point tobacco threading device further includes: a locking spring 16 and a latch 17; the locking spring 16 is elastic and is disposed on the end face of the grooved tobacco clip 12; the latch 17 is opened on the end face of the needle-type tobacco clip 11, and the latch 17 corresponds to the locking spring 16. The grooved tobacco clip 12 and the needle-type tobacco clip 11 are connected by the locking spring 16 being inserted into the latch 17.
[0058] In this technical solution, a locking spring 16 is provided on each of the two end faces of the grooved tobacco clip 12, and a bayonet 17 is provided on each of the two end faces of the needle-type tobacco clip 11. The positioning pin 110 of the needle-type tobacco clip 11 gradually embeds into the corresponding limiting groove 120. At the same time, after the locking spring 16 is squeezed by the needle-type tobacco clip 11 and gradually recovers its elastic deformation, the locking spring 16 embeds into the bayonet 17 to quickly connect the needle-type tobacco clip 11 and the grooved tobacco clip 12. At this time, lifting the needle-type tobacco clip 11 can remove the grooved tobacco clip 12 from the operating table 13 as a whole, and then remove the tobacco leaves after they have been threaded, quickly transferring the tobacco leaves. The operation is simple and convenient. When transferring the tobacco leaves, the tobacco leaves after they have been threaded are not easy to move under the dual positioning action of the positioning pin 110 and the limiting groove 120, which helps to improve the drying quality of the tobacco leaves.
[0059] Specifically, when threading the cigar, the grooved cigar clip 12 is placed into the positioning groove 14 of the operating table 13, with the limiting groove 120 facing upwards and the bottom of the limiting groove 120 flush with the surface of the operating table 13; two harvested cigar tobacco leaves are placed back-to-back into the limiting groove 120, with the base of the leaf stem aligned with the baffle 15; the locking spring 16 and the latch 17 are pressed against the surface of the needle-type cigar clip 11, causing the positioning pin 110 to insert into the main vein of the cigar tobacco leaf and reach the bottom of the limiting groove 120, and the locking spring 16 protrudes out of the latch 17, fixing the needle-type cigar clip 11 onto the grooved cigar clip 12; the two cigar clips with tobacco leaves are lifted to complete the threading operation.
[0060] like Figure 2 and Figure 5As shown, in one feasible implementation, the depth of the limiting groove 120 is equal to the length of the positioning pin 110.
[0061] In this technical solution, the depth of the limiting groove 120 is equal to the length of the positioning pin 110, so that after the positioning pin 110 is embedded in the limiting groove 120, the positioning pin 110 just touches the bottom of the limiting groove 120, ensuring that the tobacco leaves will not fall out of the gap between the positioning pin 110 and the bottom of the groove, while ensuring that the length of the positioning pin 110 does not interfere with the quick connection and locking of the needle-type cigarette clip 11 and the grooved cigarette clip 12.
[0062] As a preferred embodiment, the length of the positioning pin 110 is 40mm and the depth of the limiting groove 120 is 40mm.
[0063] like Figure 2 and Figure 5 As shown, in one feasible implementation, the center point of the bottom of the limiting groove 120 is located on the center line of the corresponding positioning pin 110.
[0064] In this technical solution, the center point of the bottom of the limiting groove 120 is located on the center line of the corresponding positioning pin 110, so that the tobacco-piercing position of the positioning pin 110 is close to the middle of the leaf petiole, preventing the main vein of the tobacco leaf from shifting and tearing during movement or drying, and improving the yield of the finished tobacco leaf after drying.
[0065] In some examples, both the needle-type cigarette clip 11 and the grooved cigarette clip 12 are provided with reinforcing ribs to improve their resistance to deformation and ensure the accuracy of the alignment between the positioning pin 110 and the limiting groove 120 after the needle-type cigarette clip 11 and the grooved cigarette clip 12 are connected.
[0066] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the width of the limiting groove 120 gradually increases from the bottom of the limiting groove 120 to the opening of the limiting groove 120.
[0067] In this technical solution, the wide-mouthed, narrow-bottomed limiting groove 120 guides the tobacco leaves into the bottom of the groove while preventing the leaf stalk from getting stuck at the opening of the groove, thereby improving the smoothness of the tobacco leaves when they are loaded into the limiting groove 120.
[0068] In one feasible implementation, the width of the bottom of the limiting groove 120 is 8mm to 12mm.
[0069] In this technical solution, the bottom width of the inverted trapezoidal limiting groove 120 is 8mm to 12mm to accommodate the differences in tobacco leaf petiole size. This ensures that the petiole is installed in place and prevents the problem of poor centering of the petiole within the limiting groove 120 caused by a large gap between the petiole and the groove wall of the limiting groove 120. This ensures that the positioning pin 110 can accurately penetrate the petiole within the corresponding limiting groove 120.
[0070] As a preferred option, the bottom width of the limiting groove 120 is 10mm and the opening width is 25mm.
[0071] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.
[0072] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
