[0035] like Figure 1 and Figure 2 As shown, according to an embodiment of this disclosure, a cigar tobacco threading device 100 is provided, including: a threading section 110; a frame 120; a conveying section 130 disposed on the frame 120, wherein, along the conveying direction of the conveying section 130, the conveying section 130 is sequentially divided into a tobacco placement area a, a threading area b, and a tobacco retrieval area c, wherein the tobacco placement area a is used to place tobacco leaves to be threaded onto the conveying section 130; the threading area b corresponds to the threading section 110; the tobacco retrieval area c is used to retrieve the tobacco leaves that have completed the threading operation; a first position detection unit is used to detect the position of the tobacco leaves on the conveying section 130, and when the tobacco leaves are detected to have reached the threading area b, the device controls the threading section 110 to perform the threading operation; an identification unit is used to identify the number of tobacco leaves threaded by the threading section 110, and when the number of tobacco leaves threaded reaches a preset number, the device controls the threading section 110 to cut the threading line.
[0036] It is understood that the cigar tobacco leaf threading device 100 provided in this embodiment includes a threading section 110, a frame 120, a conveying section 130, a first position detection section, and an identification section. The frame 120 serves as a support structure to support the conveying section 130, which is used to convey tobacco leaves. The conveying section 130 can be divided into a placement area a, a threading area b, and a retrieval area c along its conveying direction. Tobacco leaves to be threaded can be placed at the starting end of the conveying section 130 in the placement area a, conveyed to the threading area b, where the threading section 110 performs the threading operation. After threading, the tobacco leaves are conveyed to the retrieval area c via the conveying section 130 for removal. The first position detection unit detects the position of the tobacco leaves on the conveyor unit 130. When the tobacco leaves are detected to have reached the tobacco threading zone b, the tobacco threading unit 110 is activated to control the tobacco threading operation. During the tobacco threading operation, the identification unit identifies the number of tobacco leaves that have been threaded by the tobacco threading unit 110. When the identified number of tobacco leaves reaches a preset number, the tobacco threading unit 110 is controlled to cut the tobacco threading line, thereby automating the entire tobacco threading operation and enabling intelligent counting of tobacco threading operations. Throughout the entire process, the worker only needs to continuously release tobacco and remove damaged tobacco leaves. The tobacco threading operation can be completed automatically, thus avoiding manual jamming and unevenness, ensuring a continuous and uniform tobacco threading process, ensuring the consistency of tobacco leaves on the same stalk, improving the quality of the dried tobacco leaves, increasing work efficiency, and reducing labor costs.
[0037] For example, the identification unit may use infrared identification or image recognition to identify tobacco leaves.
[0038] In some examples, such as Figure 1 and Figure 2 As shown, the conveying unit 130 includes: a motor; a transmission roller 131, the motor being used to drive the transmission roller 131 to rotate; and a conveyor belt 132, wound around the transmission roller, for carrying the tobacco leaves.
[0039] Understandably, the conveying unit 130 may be equipped with a motor, a drive roller, and a conveyor belt 132. The motor may be located below the frame 120. The drive roller 131 is connected to the motor's output shaft, and the motor drives the drive roller 131 to rotate. At least two drive rollers 131 may be provided. The conveyor belt 132 is wound around the drive roller 131, carrying the tobacco leaves. Powered by the motor, the conveyor belt 132 transports the tobacco leaves, thus achieving automatic tobacco leaf transport without manual handling.
[0040] In some examples, such as Figure 1 and Figure 2As shown, there are two conveying units 130, and the conveyor belts 132 of the two conveying units 130 are arranged in parallel and spaced apart; wherein, when the tobacco leaves are placed on the conveyor belts 132, the petioles of the tobacco leaves face the gap between the two conveyor belts 132.
[0041] It is understood that two conveyor units 130 may be provided, and the conveyor belts 132 of the two conveyor units 130 are arranged in parallel, with a gap between the two conveyor units 130. When tobacco leaves are placed on the conveyor belts 132 respectively, the petioles of the tobacco leaves on the two conveyor belts 132 are arranged opposite each other with their sides facing the gap, so that the tobacco threading unit 110 can perform the tobacco threading operation on the tobacco leaves on the two conveyor belts 132, thereby improving work efficiency and ensuring uniformity. For example, each conveyor belt 132 is equipped with two drive rollers 131.
[0042] In some examples, the gap between the two conveyor belts 132 described above is 4 cm to 6 cm.
[0043] Understandably, the gap between the two conveyor belts 132 can be set to 4cm to 6cm to ensure that the stems of two rows of tobacco leaves can be placed and to facilitate the tobacco threading operation of the tobacco threading section 110. For example, a gap of 5cm can be selected.
[0044] In some examples, the inner side of the conveyor belt 132 is provided with a slot 1321 for locking and fixing the blade shank.
[0045] It is understood that a slot 1321 can be provided on the side of the conveyor belt 132 facing the gap. The slot 1321 is used to engage and fix the leaf stalk, so as to ensure that the position of the tobacco leaf is fixed during the conveying and tobacco-passing operation, improve stability, and thus ensure that the tobacco leaf passing process is continuous and uniform, ensure the consistency of tobacco leaves on the same stalk, and improve the quality of the dried tobacco leaves. For example, the slot 1321 can be a U-shaped slot 1321.
[0046] In some examples, such as Figure 1 and Figure 2 As shown, the cigar tobacco leaf feeding device 100 further includes: a pop-out part 140, corresponding to the tobacco taking area c, located below the frame 120; and a second position detection part, which controls the pop-out part 140 to lift the leaf stem when it is detected that the tobacco leaf has reached the tobacco taking area c after the feeding operation is completed.
[0047] It is understandable that the cigar tobacco threading device 100 may also be equipped with a pop-out section 140 and a second position detection section. The pop-out section 140 can be located in the tobacco taking area c, below the frame 120, corresponding to the gap between the two conveying sections 130. The second position detection section, located in the tobacco taking area c, can detect the position of the tobacco leaves. Specifically, when the second position detection section detects that the tobacco leaves, after the threading operation has been completed, have reached the tobacco taking area c, it can control the pop-out section 140 to start. The pop-out section 140 pops up from the gap to lift the stem, making it easier for the worker to remove the tobacco leaves. The worker only needs to fix the tobacco leaves at both ends to the tobacco stem and remove it to complete the threading of one stem of tobacco leaves, which is convenient and quick. The pop-out section 140 can be driven by a motor 141 to achieve automatic control of the pop-out, improving the degree of automation.
[0048] In some examples, the first position detection unit and / or the second position detection unit described above are infrared sensors.
[0049] Understandably, the first and second position detection units can use infrared sensors to detect the position of the tobacco leaves, in order to ensure detection accuracy and automation.
[0050] In some examples, the smoke-piercing part 110 described above includes a needle-sewing machine.
[0051] Understandably, a needle sewing machine can be used for the smoke-threading part 110 to perform the smoke-threading operation.
[0052] In some examples, such as Figure 1 As shown, the cigar tobacco feeding device 100 also includes a PLC (Programmable Logic Controller) device installed in the feeding area b, used to control the conveying speed of the conveying unit 130, the needle-holding speed of the needle-holding sewing machine, and to set the number of tobacco leaves fed.
[0053] It is understandable that the cigar tobacco feeding device 100 may also be equipped with a PLC device 150. Specifically, the PLC device 150 is installed in the feeding area b, and the PLC device 150 is equipped with a control panel. The conveying speed of the conveyor 130, the needle insertion speed of the needle sewing machine, and the number of tobacco leaves to be fed can be controlled on the control panel to meet different needs of the feeding operation and improve applicability.
[0054] In some examples, when the aforementioned needle sewing machine performs the tobacco threading operation on each of the aforementioned tobacco leaves, threading lines are reserved at both the front and back of each of the aforementioned tobacco leaves.
[0055] Understandably, when the needle-sewing machine is threading each tobacco leaf, its position can be controlled to leave thread at both the front and back of each tobacco leaf, allowing workers to secure the tobacco leaves using these threads for easy handling. For example, the thread at both the front and back of each tobacco leaf is 20cm.
