[0029] A storage medium stores a computer program, which can be executed by a processor to implement the steps of the method for using the vertical cigar making machine.

[0030] Beneficial technical effects of the technical solution of the present invention:

[0031] (1) The feeding mechanism includes two sprocket assemblies with opposite rotation directions. A clamping block is provided between the two sprocket assemblies. The clamping blocks are assembled to form a clamping structure. The clamping structure is evenly arranged along the feeding direction of the tobacco leaves, which can ensure that the spacing between the tobacco leaves is uniform during the weaving process. As the sprocket assembly rotates, the clamping structure is assembled one by one. The staff can conveniently clamp the petioles of the tobacco leaves to the clamping structure before the clamping structure is assembled. After the clamping structure is assembled, the petioles of the tobacco leaves can be stably clamped. Then the hook of the threading mechanism is controlled to pass through the tobacco leaf petiole, hook the weaving thread and then return it. The weaving thread can be easily threaded onto the tobacco leaf petiole. Subsequently, the staff only needs to release the clamping state of the tobacco leaf petiole and tie the weaving thread to conveniently complete the weaving of the tobacco leaves, thereby reducing the manpower requirements in the weaving process, reducing labor intensity, and improving the weaving quality and production efficiency.

[0032] (2) A sprocket assembly is movably coordinated with the frame, and the frame is also provided with a movable driving member for driving the sprocket assembly to move. When it is necessary to release the clamping state of the tobacco leaf petiole, the movable driving member is used to drive the sprocket assembly away from the other sprocket assembly, so that the clamping blocks between the two sprocket assemblies can be separated, and the clamping state of all tobacco leaf petioles can be conveniently released, further reducing manpower requirements.

[0033] (3) When the two sprocket assemblies move away from each other, there may be a problem that the tobacco leaves have not fallen off the clamping blocks. By using the movable sprocket assembly in conjunction with the baffle, and the movable push plate in conjunction with the fixed sprocket assembly, the tobacco leaves that have not fallen off the clamping blocks of the two sprocket assemblies can be pushed off.

[0034] (4) The two sprocket assemblies are meshed with each other through the transmission gears to transmit the power. The transmission gears will not prevent the sprocket assemblies from separating from each other, and can also re-engage when the two sprocket assemblies approach each other to realize the transmission function again.

[0035] (5) A guide plate is provided at the position of the sprocket assembly adjacent to the other sprocket assembly on the inner side of each sprocket assembly. The guide plate is in close contact with the inner side surface of the chain of the sprocket assembly where it is located, and can guide the chain between the two sprocket assemblies to move stably along the tobacco feeding direction, and ensure that the clamping blocks between the two sprocket assemblies can be tightly pressed.

[0036] (6) The higher end of the support rod is located near the bracket. When the bracket is rotated to an inclined position, the higher end of the support rod can receive the falling rods. The lower end of the support rod extends to the bottom of the feeding mechanism, which can easily convey the rods and facilitate the collection of the finished rods by the staff.

In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, please refer to the drawings. It should be noted that the structure, proportion, size, etc. illustrated in the drawings of this specification are only used to match the content disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the implementation conditions of the present invention, so they have no technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0057] In order to more clearly describe the above-mentioned vertical cigar making machine, method of use and storage medium, the present invention defines the terms "inside of the chain" and "outside of the chain". Specifically, "inside of the chain" refers to the side of the chain of the sprocket assembly facing the sprocket; "outside of the chain" refers to the side of the chain of the sprocket assembly facing away from the sprocket.

[0058] Example

[0059] The following will be combined with the Figures 1 to 10 The technical solutions of the vertical cigar making machine, the method of use and the storage medium of the present invention are described in detail with specific embodiments.

[0060] like Figures 1 to 10 As shown, a vertical cigar making machine of this embodiment includes a frame 1, on which are mounted:

[0061] The feeding mechanism includes a plurality of clamping structures for clamping the petioles of tobacco leaves 8. The plurality of clamping structures are evenly arranged in sequence along the length of the frame 1. The feeding mechanism also includes a driving unit for driving the clamping structures to move along the length of the frame 1. When the feeding mechanism is in operation, the clamping structures are driven to slide. In addition, each clamping structure is provided with a wire hole, the axis of which passes through the petiole of the tobacco leaf 8. The axes of the wire holes on each clamping structure coincide and are parallel to the length of the frame 1.

[0062] The threading mechanism includes a threading assembly and a thread supply assembly respectively located at both ends of the feeding mechanism. The threading assembly includes a hook 35 that can slide back and forth along the axis of the thread hole. The tip of the hook 35 is set toward the thread supply assembly. The diameter of the needle rod of the threading hook 35 is about 2-3 mm, and a barb groove (not shown in the figure) is provided on the side of the hook 35 near the tip. The axis of the hook 35 coincides with the axis of the thread hole. The thread supply assembly includes a braided cigarette line 421. After the clamping structure clamps the petiole of the tobacco leaf 8, the hook 35 is controlled to slide toward the thread supply assembly, piercing the petiole of the tobacco leaf 8 until it is close to the thread supply assembly, and then the barb groove is used to hook the braided cigarette line 421, and then slide in the opposite direction to pull the braided cigarette line 421 close to the threading assembly. The braided cigarette line 421 can be used to connect the petioles of the tobacco leaf 8 clamped by the clamping structure in series one by one. In this embodiment, the needle threading assembly is installed at the first end of the frame 1, and the wire feeding assembly is installed at the second end of the frame 1. During the process of the feeding structure feeding tobacco leaves 8, the sliding direction of the clamping structure is the direction from the first end of the frame 1 to the second end of the frame 1, and the sliding direction of the clamping structure is used as the feeding direction of the tobacco leaves 8.

[0063] The swing mechanism includes a bracket installed below the feeding mechanism. The bracket rotates with the frame 1, and the rotation axis of the bracket is parallel to the feeding direction of the tobacco leaves 8. A swing driving member 51 for driving the bracket to rotate is also connected between the frame 1 and the bracket. A tobacco braiding rod 53 is placed on the top of the bracket, which is parallel to the feeding direction of the tobacco leaves 8. The length of the tobacco braiding rod 53 is about 30 to 40 mm shorter than the hook. When the tobacco leaves 8 are clamped on the clamping structure, the bottom end of the tobacco leaves 8 is lower than the tobacco braiding rod 53. When the staff clamps the tobacco leaves 8 on the clamping structure, the tobacco leaves 8 on the adjacent clamping structures are placed on both sides of the tobacco braiding rod 53. After the tobacco leaves 8 are connected in series by the tobacco braiding line 421, the tobacco leaves 8 clamped on the clamping structure are put down, and the tobacco leaves 8 can be placed on the tobacco braiding rod 53. Then, the two ends of the tobacco braiding line 421 are tied to the tobacco braiding rod 53 to complete the tobacco braiding.

[0064] The collecting structure is installed on one side of the bracket. The collecting structure includes two supporting rods 6 for supporting the tobacco rod 53. The two supporting rods 6 are parallel to each other and arranged along the feeding direction of the tobacco leaves 8. The supporting rods 6 are tilted. The end of the supporting rod 6 close to the tobacco rod 53 is higher, and the lower end of the supporting rod 6 extends to the outside of the frame 1. The lower end of the supporting rod 6 is integrally connected with a stopper 61, and the stopper 61 extends upward and protrudes from the side of the supporting rod 6. When the bracket swings and drives the tobacco rod 53 close to the collecting structure, the tobacco rod 53 slides down from the top of the bracket and is received by the two supporting rods 6. Then the tobacco rod 53 can slide down along the supporting rod 6 until it abuts against the stopper 61. The supporting rod 6 can conveniently output the tobacco rod 53 after the tobacco is woven to the outside of the frame 1, making it convenient for the staff to take it.

[0065] Specifically, the drive unit includes two sprocket assemblies 2 installed inside the frame 1. The two sprocket assemblies 2 are arranged along the length direction of the frame 1 and are respectively located on the left and right sides of the frame 1. The sprocket axes of the sprocket assemblies 2 are arranged in the vertical direction, and the two sprocket assemblies 2 rotate in opposite directions. A plurality of clamping blocks 23 are connected to the outer side of the chain of the sprocket assembly 2, and the plurality of clamping blocks 23 are evenly arranged along the length direction of the chain of the sprocket assembly 2. The clamping blocks 23 of the two sprocket assemblies 2 are positioned one-to-one, and the clamping block 23 located between the two sprocket assemblies 2 is tightly fitted with the side of the corresponding clamping block 23. The side of the clamping block 23 facing away from the chain is provided with a notch 231 arranged in the vertical direction and a avoidance groove 232 arranged in the horizontal direction. The avoidance groove 232 is connected to the side wall of the notch 231. When the corresponding clamping blocks 23 between the two sprocket assemblies 2 are tightly fitted, the clamping blocks 23 combine to form a clamping structure for clamping tobacco leaves 8. The notches 231 combine to form a clamping hole for clamping the petiole of the tobacco leaf 8, and the avoidance grooves 232 combine to form a linear hole. In addition, a foam sheet is adhered to the inner wall of the notch 231 to alleviate the pressure of the clamping blocks 23 on the petiole of the tobacco leaf 8 and prevent the petiole of the tobacco leaf 8 from being damaged.

[0066] When the sprocket assembly 2 is running, the clamping block 23 that reaches the first end of the frame 1 is assembled with the corresponding clamping block 23 to form a clamping structure. As the sprocket assembly 2 drives the clamping structure to move to the second end of the frame 1, the two clamping blocks 23 that form the clamping structure separate. When performing the tobacco weaving operation, the first end of the frame 1 is used as the clamping station, and the sprocket assembly 2 is controlled to operate stepwise. At the clamping station, the staff will load the petioles of two tobacco leaves 8 with their backs facing each other into the notches 231 of the clamping blocks 23 to be assembled. The leaves of the tobacco leaves 8 are located below the clamping blocks 23, the bottom ends of the leaves of the tobacco leaves 8 are lower than the weaving rod 53, and the top ends of the petioles of the tobacco leaves 8 are higher than the top surfaces of the clamping blocks 23. The sprocket assembly 2 then drives the clamping blocks 23 to move until the next set of corresponding clamping blocks 23 are about to be assembled. The clamping blocks 23 that have been loaded with tobacco leaves are assembled to form a clamping structure and clamp the petioles of the tobacco leaves 8. The worker then loads two more tobacco leaves 8 into the clamping structure that is about to close. Repeating this process allows tobacco leaves 8 to be sequentially loaded into each clamping structure and fed toward the second end of the frame 1. Furthermore, after the tobacco leaf 8's petiole is clamped by the clamping structure, the tobacco leaves 8 in adjacent clamping structures should be positioned on either side of the braided tobacco rod 53. That is, the tobacco leaves 8 arranged along the feeding direction of the tobacco leaves 8 are staggered on either side of the braided tobacco rod 53. Once the tobacco leaves 8 are connected in series by the braiding line 421, the clamping structure is controlled to lower the tobacco leaves 8, allowing the series of tobacco leaves 8 to rest on the braided tobacco rod 53.

[0067] In this embodiment, both sides of the notch 231 are connected to the side surfaces of the adjacent clamping block 23 with avoidance grooves 232, that is, both side walls of the clamping hole are connected to wire holes, and the hook needle 35 can pass through the clamping structure by passing through the two wire holes of the clamping structure in turn.

[0068] Furthermore, one of the sprocket assemblies 2 is fixedly mounted on the frame 1, while the other sprocket assembly 2 is integrally slidably engaged with the frame 1, with the sliding direction being arranged horizontally and perpendicular to the feeding direction of the tobacco leaves 8. The frame 1 is also provided with a movable drive member 111 for driving the movable sprocket assembly 2 to slide. When the movable drive member 111 drives the movable sprocket assembly 2 to approach the fixed sprocket assembly 2, the clamping blocks 23 between the two sprocket assemblies 2 can be assembled one by one; and when the movable sprocket assembly 2 moves away from the fixed sprocket assembly 2, the clamping blocks 23 between the two sprocket assemblies 2 are simultaneously separated. When the tobacco leaves 8 are connected in series by the tobacco weaving line 421, the movable sprocket assembly 2 is driven away from the fixed sprocket assembly 2, and the clamping state of the tobacco leaves 8 by all clamping structures can be released at the same time, and the tobacco leaves 8 can fall onto the tobacco weaving rod 53. There is no need for the staff to loosen the tobacco leaves 8 one by one, which is convenient for use and can improve tobacco weaving efficiency.

[0069] Specifically, a first sliding frame 11 is slidably mounted on the frame 1. The sliding direction of the first sliding frame 11 is perpendicular to the feeding direction of the tobacco leaves 8 and is arranged in the horizontal direction. A pair of base plates 14 are bolted to both the frame 1 and the first sliding frame 11. The base plates 14 of the same pair are arranged along the feeding direction of the tobacco leaves 8. The two base plates 14 of the same pair are used to mount two sprockets of a sprocket assembly 2. The sprocket assembly 2 mounted on the base plates 14 of the first sliding frame 11 is a movable sprocket assembly 2. The movable driving member 111 is a cylinder. The cylinder is fixedly mounted on the frame 1, and the length direction of the cylinder is parallel to the sliding direction of the first sliding frame 11. The piston rod of the cylinder is connected to the first sliding frame 11. When the piston rod of the cylinder is extended or retracted, it can drive the first sliding frame 11 and the movable sprocket assembly 2 to move closer to or away from the fixed sprocket assembly 2.

[0070] It should be noted that the movement of the movable sprocket assembly 2 toward or away from the fixed sprocket assembly 2 is not limited to sliding, and can also be swinging. In addition, the direction of sliding is not limited to the aforementioned horizontal and perpendicular direction of the supply of tobacco leaves 8, and any direction can be used as long as it can cause the corresponding clamping blocks 23 to be joined or separated.

[0071] Furthermore, the frame 1 and the first sliding frame 11 are both bolted with a guide plate 24, and the two guide plates 24 are respectively located on the inner sides of the chains of the two sprocket assemblies 2. The guide plates 24 are extended along the feeding direction of the tobacco leaves 8 and are tightly fitted against the inner side surfaces of the chain of the sprocket assembly 2 close to the clamping structure. The two guide plates 24 can guide the chain of the sprocket assembly 2 to run smoothly, so that the clamping blocks 23 between the two sprocket assemblies 2 remain in a tightly fitted state, preventing the tobacco leaves 8 from falling off from between the two clamping blocks 23 that constitute the clamping structure.

[0072] Furthermore, the frame 1 is also equipped with a fixed baffle 13, a second sliding frame 12 that slides with the frame 1, and a sliding drive 121 for driving a push plate 122 to slide. The sliding drive 121 is a pneumatic cylinder. The sliding direction of the second sliding frame 12 is parallel to the sliding direction of the first sliding frame 11. The second sliding frame 12 is equipped with a push plate 122. The push plate 122 and the baffle 13 are both arranged parallel to the feeding direction of the tobacco leaves 8. The baffle 13 is located above the movable sprocket assembly 2, while the push plate 122 is located above the fixed sprocket assembly 2. When the second sliding frame 12 drives the push plate 122 to slide, the push plate 122 can pass directly above the fixed sprocket assembly 2. When the first sliding frame 11 drives the movable sprocket assembly 2 to slide, the sprocket assembly 2 passes directly below the baffle 13. When the clamping block 23 between the two sprocket assemblies 2 is located directly below the push plate 122 or the baffle 13, the distance between the push plate 122 or the baffle 13 and the clamping block 23 is less than the length of the top of the tobacco leaf 8's petiole extending out of the clamping block 23. Then, when the clamping block 23 and the push plate 122 or the baffle 13 move relative to each other and reach directly below the push plate 122 and the baffle 13, if the tobacco leaf 8's petiole is still stuck in the notch 231 of the clamping block 23, the push plate 122 and the baffle 13 can push the tobacco leaf 8's petiole extending above the clamping block 23 out of the notch 231, causing the tobacco leaf 8 to fall off the clamping block 23. Alternatively, the push block and the baffle 13 can be installed below the sprocket assembly 2, and the push block and the baffle 13 can directly push the tobacco leaf 8 to slide down, which can also achieve the same effect.

[0073] In the present embodiment, the feeding mechanism further includes a feeding drive 21 for driving the fixed sprocket assembly 2 to operate. The feeding drive 21 is a motor, and a pulley assembly is provided between the output shaft of the feeding drive 21 and the sprocket shaft of the fixed sprocket assembly 2 near the first end of the frame 1. In addition, the sprockets of the two sprocket assemblies 2 near the second end of the frame 1 are coaxially connected to a transmission gear 22, and the transmission gear 22 rotates synchronously with the sprockets. When the two sprocket assemblies 2 approach each other until the clamping block 23 is spliced ​​to form a clamping structure, the two transmission gears 22 engage. Subsequently, if the fixed sprocket assembly 2 begins to rotate, it can drive the movable sprocket assembly 2 to rotate in the opposite direction. The transmission is carried out by the meshing of the transmission gears 22, which does not hinder the separation of the two sprocket assemblies 2. When the two sprocket assemblies 2 approach each other, they can re-engage, realizing the transmission function again, which is compatible with the matching relationship of the sprocket assemblies 2 in the present embodiment.

[0074] Furthermore, a mounting bracket 3 is placed at the first end of the frame 1. The needle threading assembly includes a needle guide tube 15 and a guide cylinder 34 for the hook needle 35 to pass through, a needle feed wheel 33 that abuts against the side of the hook needle 35, and a rotating drive member 321 for driving the needle feed wheel 33 to rotate. The needle guide tube 15 is mounted at the first end of the frame 1, and the guide cylinder 34 and the needle feed wheel 33 are arranged on the mounting bracket 3. The needle feed wheel 33 is rotatably mounted between the needle guide tube 15 and the guide cylinder 34. The axes of the needle guide tube 15 and the guide cylinder 34 coincide with the axis of the thread hole. The tip of the hook needle 35 is positioned toward the second end of the frame 1. When the hook needle 35 passes through the needle guide tube 15 and the guide cylinder 34, the side of the hook needle 35 is in contact with the inner walls of the needle guide tube 15 and the guide cylinder 34, and a sliding fit is achieved. The needle feeding wheel 33 abuts against the side of the hook needle 35 through its own circumferential side. When the needle feeding wheel 33 rotates, the friction between the needle feeding wheel 33 and the hook needle 35 can drive the hook needle 35 to slide back and forth along the axis of the thread hole, so that the tip of the hook needle 35 passes through the petiole of the tobacco leaf 8, and brings back the hooked braided tobacco thread 421, connecting the petioles of the tobacco leaves 8 in series.

[0075] In this embodiment, the needle feed wheels 33 are arranged in pairs, with a total of two pairs. The two pairs of needle feed wheels 33 are arranged along the axis of the hook needle 35, and the two needle feed wheels 33 in the same pair are respectively located on either side of the hook needle 35. A groove 331 is formed on the circumferential side of the needle feed wheel 33. The side surface of the hook needle 35 is embedded in the groove 331 of the two needle feed wheels 33 in the same pair. The cross-section of the groove 331 is adapted to the cross-section of the hook needle 35, and the groove wall of the groove 331 is in contact with the side surface of the hook needle 35. This changes the contact between the needle feed wheel 33 and the hook needle 35 from point contact to line contact, making it easier for the needle feed wheel 33 to drive the hook needle 35 to slide.

[0076] Specifically, the top surface of the mounting frame 3 is bolted to two parallel plates 31. Two pairs of rotating shafts 32 are rotatably mounted between the two plates 31. The axes of the rotating shafts 32 are arranged horizontally and perpendicular to the axis of the hook 35. The two pairs of rotating shafts 32 are aligned along the axis of the hook 35, with the two rotating shafts 32 in the same pair aligned vertically. Two needle feed wheels 33 are mounted on the same pair of rotating shafts 32. The needle feed wheels 33 rotate synchronously with the rotating shafts 32 and are located above and below the hook 35, respectively. A gear set is installed between the two rotating shafts 32 in the same pair for rotation, and a pulley set is installed between the two pairs of rotating shafts 32 for transmission. In addition, the rotating drive member 321 is a motor bolted to the mounting frame 3, and a pulley set is also installed between the output shaft of the rotating drive member 321 and a rotating shaft 32 for transmission. When the motor is running, it can drive the two pairs of rotating shafts 32 to rotate, and the two rotating shafts 32 in the same pair rotate in opposite directions. When the rotating shaft 32 rotates, it can drive the needle feeding wheel 33 to rotate and drive the crochet hook 35 to slide along the axis of the crochet hook 35. By adjusting the running direction of the motor, the crochet hook 35 can be driven to slide in the opposite direction.

[0077] Specifically, the wire supply assembly includes a base 4 bolted to the second end of the frame 1. A rod 41 is vertically welded to the base 4. A bobbin 42, wound with a braided cigarette thread 421, is sleeved on the outside of the rod 41. The bobbin 42 can freely rotate around the rod 41. The bottom end of the rod 41 is connected to the base 4. The top side of the rod 41 is threaded, and a threaded member 43 is threadedly connected to it. An elastic member 44 is disposed between the threaded member 43 and the top surface of the bobbin 42, and the threaded member 43 abuts against the top surface of the bobbin 42 through the elastic member 44. When the hook 35 hooks the braided cigarette thread 421 and pulls the braided cigarette thread 421 toward the first end of the frame 1, the threaded member 43 is screwed in or out to adjust the tightness of the elastic member 44 against the bobbin 42, thereby changing the resistance to the rotation of the bobbin 42 and keeping the braided cigarette thread 421 in a taut state. In addition, a thread take-up lever 46 is bolted to the base 4. One end of the thread take-up lever 46 is bent to form a slot for the braided cigarette thread 421 to pass through. The slot of the thread take-up lever 421 opens upward, and the braided cigarette thread 421 pulled out of the spool 42 can be placed in the slot of the thread take-up lever 46, preventing it from falling off. In this embodiment, the elastic member 44 is a spring, which is sleeved on the rod body 41. The rod body 41 also has an annular pressure plate 45 movably sleeved on it. The pressure plate 45 is located between the spring and the spool 42, and the two ends of the spring are respectively pressed against the threaded member 43 and the pressure plate 45.

[0078] Specifically, the bracket includes a rod body 5 arranged in the horizontal direction. The rod body 5 is located directly below the feeding mechanism. Both ends of the rod body 5 are fixedly connected to support members 52. The support members 52 are arranged in the vertical direction. Pins are provided through the two support members 52. The pins and the support members 52 are rotatably engaged. The axes of the two pins coincide and are parallel to the feeding direction of the tobacco leaves 8. The pins on the two support members 52 are bolted to the first and second ends of the frame 1 respectively. The bracket can rotate around the axes of the two pins. A swing drive member 51 is connected between the rod body 5 and the frame 1. The swing drive member 51 is a cylinder. The length direction of the cylinder is perpendicular to the rotation axis of the bracket. The cylinder body is hinged to the frame 1. The piston rod of the cylinder is hinged to the rod body 5. When the cylinder pushes the rod body 5 to rotate, the cylinder itself can also deflect. In addition, a placement groove 521 for placing the braided cigarette rod 53 is provided on the top of the support member 52. The placement groove 521 passes through both sides of the support member 52 along the feeding direction of the tobacco leaves 8. When the braided cigarette rod 53 is placed on the two support members 52, the two ends of the braided cigarette rod 53 are respectively placed in the placement groove 521 of the two support members 52.

[0079] A collection structure is also installed on the frame 1. The collection structure is located on one side of the bracket and includes two support rods 6 for supporting the tobacco rod 53. The two support rods 6 are parallel to each other and arranged along the feeding direction of the tobacco leaves 8. The support rods 6 are tilted, and the end of the support rod 6 close to the tobacco rod 53 is higher, and the lower end of the support rod 6 extends to the outside of the frame 1. The lower end of the support rod 6 is integrally connected with a stopper 61, and the stopper 61 extends upward and protrudes from the side of the support rod 6. When the bracket swings and drives the tobacco rod 53 close to the collection structure, the tobacco rod 53 slides down from the top of the tilted bracket and is received by the two support rods 6. Then the tobacco rod 53 can slide down along the support rod 6 until it abuts against the stopper 61. The support rod 6 can easily output the tobacco rod 53 after the tobacco is woven to the outside of the frame 1, making it convenient for the staff to take it.

[0080] In addition, a control device 7 is also provided on the mounting frame 3. The control device 7 includes a PLC programmable controller (not shown in the figure) and multiple control switches 71. The PLC programmable controller is used to control the automatic operation of the above-mentioned moving drive member 111, sliding drive member 121, rotating drive member 321 and swinging drive member 51, but the staff can also manually control the operation of the moving drive member 111, sliding drive member 121, rotating drive member 321 and swinging drive member 51 through the control switch 71.

[0081] It should be noted that the feeding mechanism can also use a sliding member that slides along the feeding direction of the tobacco leaves 8. The sliding member is equipped with a uniformly arranged clamping structure, and the sliding member is used to drive the tobacco leaves 8 to be fed forward. After completing one cigarette arrangement, the sliding member should be slid in the opposite direction to reset. When the cigarette is arranged again, the sliding member can drive the clamping structure to pass in front of the staff in turn, making it convenient for the staff to clamp the tobacco leaves 8 to the clamping mechanism. Since it is necessary to control the sliding member to slide in the opposite direction, the initial position of the sliding member should be avoided from interfering with the needle threading assembly, such as setting the initial position of the sliding member at the second end of the frame 1. In addition, the clamping structure can also use a clamp with a wire hole. The tobacco leaves 8 can be conveniently clamped or removed by opening and closing the clamp.

[0082] The wire supply assembly can also be selected from other containers for temporarily storing the braided cigarette thread 421, or the wire supply assembly only includes the braided cigarette thread 421. When the hook groove of the hook needle 35 hooks the braided cigarette thread 421 and drives the braided cigarette thread 421 through the petiole of the tobacco leaf 8, the staff can even directly hold the braided cigarette thread 421 to tighten the braided cigarette thread 421.

[0083] A method for using a vertical cigar making machine, applicable to the above-mentioned vertical cigar making machine, comprises the following steps:

[0084] S1. Control the movement of the clamping structure along the tobacco leaf 8 feeding direction;

[0085] S2. The staff from the feeding mechanism next to the clamping structure in front of the sequential clamping tobacco leaves 8, the adjacent clamping structure holding the tobacco leaves 8 are placed on both sides of the tobacco rod 53;

[0086] S3. When enough tobacco leaves are clamped 8, the feeding mechanism is stopped;

[0087] S4. Control the tip of the hook 35 to slide toward the wire assembly so that the tip of the hook 35 passes through the petiole of all tobacco leaves 8 in sequence;

[0088] S5. The hook groove of the hook 35 is hooked to take the tobacco line 421, and the hook 35 is controlled to slide back to the line supply assembly until the hook 35 is disengaged from the petiole of all tobacco leaves 8, so that the petiole of the tobacco leaves 8 is woven in series with the tobacco line 421;

[0089] S6 release the clamping structure of the tobacco leaves 8, so that the tobacco leaves 8 rest on the tobacco rod 53;

[0090] S7. The cigarette line 421 is tied to the cigarette rod 53;

[0091] S8. The control feeding mechanism is reset, a new cigarette rod 53 is replaced, and the above operation is repeated.

[0092] When controlling the clamping structure to move along the feeding direction of the tobacco leaf 8, the clamping structure can be driven to move in a step-by-step manner. The clamping structure in this embodiment is assembled one by one as the sprocket assembly 2 rotates. Therefore, the sprocket assembly 2 can be controlled to stop rotating once before each group of corresponding clamping blocks 23 are assembled to form the clamping structure, so that the staff can place the petiole of the tobacco leaf 8 between the corresponding clamping blocks 23.

[0093] After the hook 35 drives the braided cigarette thread 421 to string the petioles of the tobacco leaves 8 together one by one, the staff needs to cut the braided cigarette thread 421 so that the length of the two ends of the braided cigarette thread 421 extending out of the petioles of the tobacco leaves 8 is approximately 200 mm. Then the staff can tie the ends of the braided cigarette thread 421 to the braided cigarette rod 53.

[0094] In this embodiment, the method for releasing the clamping state of the tobacco leaves 8 by the clamping structure is to control the movable sprocket assembly 2 to slide away from the fixed sprocket assembly 2. When one cigarette-making operation is completed and the next cigarette-making rod 53 is to be made, the movable sprocket assembly 2 needs to be controlled to reset and move closer to the fixed sprocket assembly 2 again, so that the clamping blocks 23 between the two sprocket assemblies 2 are correspondingly abutted and pressed. A storage medium stores a computer program on the storage medium. When the computer program is executed by a processor, the steps of the above-mentioned method for using the vertical cigar making machine are implemented. The storage medium is a non-transitory computer-readable storage medium. The storage medium can be a magnetic disk, an optical disk, a read-only memory (ROM), a random access memory (RAM), a flash memory, a hard disk drive (HDD), or a solid-state drive (SSD). In addition, the storage medium can also include a combination of the above-mentioned types of memory.

[0095] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
