The output plate 45 is provided with a matching cavity for accommodating the output tooth 42.

[0087] Based on the above structure, when the second motor 32 operates, it will drive the four sprockets to rotate, and at the same time drive the output shaft 41 to rotate, thereby synchronously driving the output strip to rotate. When the cigar embryo is lifted to the top position, the limiting groove 35 will move downward under the action of the lifting chain plate 34. At this time, the cigar embryo is placed on the two transmission strips 44, and is transported to the output plate 45 through the transmission strips 44, and is finally transported outward.

[0088] As an example, the transmission strip 44 is provided as two strips, and the gap between the two transmission strips 44 is not less than the size of the limiting groove 35, and not greater than the size of the cigar embryo to be transported, so that the cigar embryo can be stably transported during the handover.

At the same time, the detachable access side plate 47 is arranged on both sides of the support frame 31, which can facilitate the maintenance and repair of the lifting sprocket 33, and ensure the stability of the whole device.

[0091] Through the device, the cigar embryo can be efficiently and stably transported to a high place, facilitating subsequent processing of the cigar embryo. At the same time, the access door 46 for repairing the lifting position of the lifting part 3 is arranged, which facilitates the processing of the internal cigar embryo. At the same time, the detachable access side plate is arranged on both sides of the support frame 31, which facilitates the repair of the internal components.

[0100] As an example, the inclined surface between the first driven roller 1612 and the power roller 1611 is opposite to the first inclined plate 1631, forming a first guide channel for the cigar embryo 1007, and the second inclined plate 1632 and the second baffle 1063 form a second guide channel.

[0101] Based on the above structure, the cigar embryo 1007 is guided to the front end position of the material distribution assembly 1005 through the first guide channel, when the material is too much and stacked in the front end position, the cigar embryo 1007 will be guided to the rear end of the material distribution assembly 1005 from the second guide channel, so as to avoid the material from being stacked on the top of the middle area of the material distribution assembly 1005, thereby causing the weight of the cigar embryo 1007 to be too large to cause damage to the bottom cigar embryo 1007 when the material distribution roller rotates, in short, the pressure of the cigar embryo 1007 on the upper end of the material distribution assembly 1005 is released.

[0102] As an example, the distributing assembly 1005 can include a distributing drum 1051, a feeding transfer disc 1052, and an anti-blocking wheel 1053; the feeding transfer disc 1052 is arranged close to the distributing drum 1051, and the anti-blocking wheel 1053 is arranged in the area between the distributing drum 1051 and the feeding transfer disc 1052; the output end of the power assembly 1004 is connected to the center position of the distributing drum 1051.

[0109] As an example, the circumferential position of the distribution drum 1051 is uniformly provided with a plurality of material carrying grooves 1054 which are suitable for the size of the cigar embryo 1007, and a plurality of matching grooves 1055 are also provided on the distribution drum 1051, the matching grooves 1055 are at least provided in two along the width direction of the distribution drum 1051; The first side plate 1031 and the second side plate 1032 are also provided with a material taking plate 1056 which is inserted into the matching groove 1055;

[0110] Based on the above mechanism, the rotation of the distribution drum 1051 will make the cigar embryo 1007 falling into the material carrying groove 1054 rotate, when rotating to the material taking plate 1056, the cigar embryo 1007 is clamped by the material taking plate 1056, and enters the feeding transfer disc 1052, realizing precise assembly and transfer. The distribution drum 1051, the feeding transfer disc 1052 and the material taking plate 1056 in the present scheme are all prior art, and will not be described here.

[0112] Based on the above structure, when moving, the distribution drum 1051 is clockwise, at the joint of the anti-blocking wheel 1053 and the distribution drum 1051, the excess cigar embryo 1007 is isolated, so that only one cigar embryo 1007 can pass between the material clamping plate 1057 and the distribution drum 1051. During the feeding process, the anti-blocking wheel 1053 also rotates clockwise, and the outer diameter linear velocity is greater than that of the distribution drum 1051, so that the round head embryo which is not dropped into the material carrying groove 1054 of the distribution drum 1051 can be prevented from being clamped, and the damage of the cigar embryo 1007 is avoided.

When the tobacco drill bit 2417 is assembled in the connecting through hole, the tobacco drill bit 2417 is locked by the locking bolt to prevent the tobacco drill bit 2417 from falling off.

[0143] As an example, the tobacco drill bit 2417 can include a connecting rod 2422 and a rotating head rod 2423. The rotating head rod 2423 is in a whole conical structure, at least two material guide grooves 2424 are arranged on the rotating head rod 2423, the material guide grooves 2424 are spirally arranged along the length direction of the rotating head rod 2423, and a cutting head 2425 is arranged at the end of the rotating head rod 2423.

[0144] Based on the above structure, when the tobacco drill bit 2417 is driven to rotate, the cutting head 2425 rotates the end of the cigar embryo under the action of the double guide structure, and the tobacco is discharged along the material guide grooves 2424 and collected by the collecting part. Meanwhile, the rotating head rod 2423 is in a conical structure, so that the hollowed-out end of the cigar embryo is also in a conical structure, which facilitates the formation of a minimum end face at the end during the later hot-pressing forming.

[0145] As an example, the rotating spinning module 2400 is arranged at multiple positions along the circumferential direction of the first connecting ring 2204 and the second connecting ring 2205, and the tobacco drill bit 2417 connected to the first connecting ring 2204 and the second connecting ring 2205 is arranged to the central connecting piece 2206.

[0146] As an example, an auxiliary driving member is arranged at the top of the spinning rotating wheel 2200, and an auxiliary abutting member is further arranged on both sides of the spinning rotating wheel 2200. The auxiliary driving member is used to provide power for the matched sleeve wheel 2419, so that the rotating head 2404 rotates at a predetermined position, and the auxiliary abutting member is used to adjust the depth of the tobacco drill bit 2417 selected into the cigar embryo.

[0147] Based on the above structure, the auxiliary driving member is used to provide power for the matched sleeve wheel 2419 at a predetermined position, and the auxiliary abutting member contacts the follow-up wheel at a predetermined position, so as to force the spinning sliding seat 2402 to slide and change the infeed amount of the rotating head 2404 in the cigar embryo.

[0148] As an example, the auxiliary driving member can include a driving support 2426, an auxiliary positioning rod 2427, an auxiliary motor 2428 and a guide wheel assembly. The driving support 2426 is connected to the spinning support 2100 through a connecting rod, the auxiliary positioning rod 2427 is arranged between the two driving supports 2426 respectively, the auxiliary motor 2428 is arranged on the driving support 2426, and an auxiliary driving belt 2429 can be arranged between the guide wheel assembly and the output end of the auxiliary motor 2428.

[0149] Based on the above structure, the driving supports 2426 on both sides of the yarn extraction roller 2200 can be connected through the auxiliary positioning rod 2427 to ensure the positional consistency of the two, and power can be provided to the matching sleeve roller 2419 synchronously and accurately. The auxiliary motor 2428 rotates to drive the auxiliary driving belt 2429 to rotate, thereby outputting rotary force outward.

[0150] As an example, the driving support 2426 can include a main driving support 2430 and an auxiliary support 2431. The auxiliary support 2431 is arranged at one end of the main driving support 2430, and the auxiliary support 2431 is arranged symmetrically along the central position of the main driving member. The auxiliary support 2431 is arranged at a predetermined angle with the main driving support 2430. The guide roller assembly can include a main guide roller 2432, a tensioning roller 2433, and a matching roller 2434. The main guide roller 2432 is arranged at the top position of the main driving support 2430. The tensioning roller 2433 is arranged symmetrically at the bottom position of the main driving support 2430. The matching roller 2434 is arranged at the end position of the auxiliary support 2431. The auxiliary driving belt 2429 is arranged around the main guide roller 2432, the tensioning roller 2433, and the matching roller 2434.

[0151] Based on the above structure, since the auxiliary support 2431 is arranged at a predetermined angle with the main driving support 2430, when the auxiliary driving belt 2429 is sleeved on the main guide roller 2432, the tensioning roller 2433, and the matching roller 2434, a linear auxiliary driving belt 2429 will be formed between the two matching rollers 2434. However, since the yarn extraction roller 2200 is a circular structure, the rotating yarn extraction module 2400 thereon is also arranged along the circumferential direction of the yarn extraction roller 2200. Therefore, the linear auxiliary driving belt 2429 will be deformed by being squeezed by the rotating yarn extraction modules 2400 that are at two horizontal heights above the matching rollers 2434, thereby enabling the auxiliary driving belt 2429 to drive the rotating yarn extraction modules 2400 at two horizontal heights above the matching rollers 2434 with driving force, thereby driving the matching sleeve roller 2419 to rotate, achieving power input. That is, the rotating yarn extraction modules 2400 on the yarn extraction roller 2200 will only obtain driving force for rotation when they move to a high position. On the one hand, this can ensure that the cigar blank is clamped before being rotated, ensuring the yarn extraction force and efficiency. On the other hand, it can also avoid unnecessary idling and waste of energy.

[0152] As an example, a limiting wheel set 2435 can be arranged at a position near the matching roller 2434 on the auxiliary support 2431. The limiting wheel set 2435 can be provided with two rotating wheels that can rotate freely. The auxiliary driving belt 2429 is arranged between the two rotating wheels.

[0153] Based on the above structure, the driving belt is limited between the two rotating wheels, so that the driving belt can only rotate at a predetermined angle, avoiding the occurrence of derailment and improving the overall stability.

[0154] As an example, the auxiliary abutting piece is arranged on the spinning support plate 2101, which can include an auxiliary support plate 2436 and an arc-shaped abutting block 2437; the auxiliary support plate 2436 is fixedly connected with the spinning support plate 2101, and the arc-shaped abutting block 2437 is arranged perpendicularly to the auxiliary support plate 2436, and the protruding direction of the arc-shaped abutting block is consistent with the feeding direction of the rotating head 2404;

[0155] The arc-shaped abutting block includes a first abutting end 2438, a second abutting end 2439 and a third abutting end 2440; the thickness of the arc-shaped abutting block gradually increases from the first abutting end 2438 to the second abutting end 2439, and gradually decreases from the second abutting end 2439 to the third abutting end 2440; and the arc-shaped profile formed by the first abutting end 2438, the second abutting end 2439 and the third abutting end 2440 matches the running track of the follower wheel.

[0156] Based on the above structure, the follower wheel rotates with the spinning rotating wheel 2200, when the follower wheel enters the area of the arc-shaped abutting block, the follower wheel contacts the first abutting end 2438, the second abutting end 2439 and the third abutting end 2440, when the follower wheel moves from the first abutting end 2438 to the second abutting end 2439, the arc-shaped abutting block forces the follower wheel to gradually feed the end part of the cigar blank for spinning operation, when the follower wheel moves from the second abutting end 2439 to the third abutting end 2440, the reset spring 2408 in the follower wheel forces it to reset, so that the end part of the cigar blank is gradually withdrawn, and the whole process is realized by the special design of the structure, which realizes automatic operation without additional electronic detection setting, and can efficiently and stably perform spinning operation, and the cost is also lower.

[0157] As an example, the spinning gripper 2500 can include a fixed gripper 2501, a movable gripper 2502, a connecting arm 2503 and a trigger wheel 2504; the fixed gripper 2501 is fixed on the support ring surface 2212, part of the end of the movable gripper 2502 is arranged through the gripper through slot 2213, the connecting arm 2503 is connected with the movable gripper 2502 at a predetermined angle, and the trigger wheel 2504 is arranged on the end of the connecting arm 2503 away from the movable gripper 2502; the movable gripper 2502 is hinged with the fixed gripper 2501;

[0158] A first connecting column 2505 is arranged on the end of the connecting arm 2503 close to the trigger wheel 2504, a second connecting column 2506 is arranged in the area between adjacent gripper through slots 2213, and a first spring 2507 is arranged between the first connecting column 2505 and the second connecting column 2506;

[0159] The trigger 2508 is arranged on the yarn drawing support 2100, and is arranged at an inner position of the central connecting piece 2206. The trigger 2508 can include a first trigger end 2509, a second trigger end 2510 and a resisting arc plate 2511. The first trigger end 2509 and the second trigger end 2510 are respectively arranged at two ends of the resisting arc plate 2511. The first trigger end 2509 is provided with a first slope 2512. The second trigger end 2510 is provided with a second slope 2513. The arc of the resisting arc plate 2511 is matched with the arc of the whole supporting ring surface 2212. The distance between the resisting arc plate 2511 and the supporting ring surface 2212 is less than the length of the connecting arm 2503.

[0160] Based on the above structure, since the movable clamp jaw 2502 is hinged with the fixed clamp jaw 2501, the action of the movable clamp jaw 2502 realizes the opening and closing of the whole yarn drawing clamp jaw 2500. When the trigger wheel 2504 rolls to contact the resisting arc plate 2511, the movable clamp jaw 2502 is forced to move away from the fixed clamp jaw 2501, so that the whole yarn drawing clamp jaw 2500 is opened. When the trigger wheel 2504 rolls to the first slope 2512 on the first trigger end 2509, the movable clamp jaw 2502 is forced to move close to the fixed clamp jaw 2501 under the pulling of the first spring 2507, so that the whole yarn drawing clamp jaw 2500 is closed. Until the second slope 2513 of the second trigger end 2510 is reached, the yarn drawing clamp jaw 2500 is closed again. In this way, the yarn drawing clamp jaw 2500 on the yarn drawing wheel 2200 is periodically opened and closed at a predetermined position under the rotation of the yarn drawing wheel 2200, accepts the cigar blank from the upper end, and then continuously clamps the cigar blank for drawing operation. Finally, at the second trigger end 2510, the cigar blank that has been drawn is released, and the yarn drawing clamp jaw is opened to enter the next process.

[0161] For example, the movable clamp jaw 2502 and the fixed clamp jaw 2501 are provided with arc-shaped grooves 2514 matched with the cigar blank. On the one hand, the arc-shaped grooves 2514 can position the cigar blank. On the other hand, the arc-shaped grooves 2514 can avoid continuous clamping from causing damage to the cigar blank.

[0162] For example, the hot-press forming assembly at least includes, but is not limited to, a forming wheel disc 3100, an electric slip ring 3200, a hot forming structure 3300, a variable-diameter cam assembly 3400 and a driving part 3500. The hot forming structure 3300 is uniformly arranged along the circumferential position of the forming wheel disc 3100. The electric slip ring 3200 is connected with the hot forming structure 3300. The driving part 3500 is connected with the forming wheel disc 3100 and can rotate the forming wheel disc 3100. The hot forming structure 3300 is provided with a matching part matched with the variable-diameter cam assembly 3400. The matching part is circumferentially arranged around the variable-diameter cam assembly 3400 and periodically opens or closes the clamping part of the cigar blank along the contour of the variable-diameter cam assembly 3400.

[0163] Based on the above structure, the forming wheel disc 3100 obtains the cigar blank from the upstream at a specified position, and clamps the cigar blank through the clamping part. The electric slip ring 3200 supplies power to all the heat forming structures 3300 on the forming wheel disc 3100, so that the heat forming structures 3300 can heat and form the end of the cigar blank in the clamped state. The heat forming structures 3300 move along the outer contour of the variable-diameter cam assembly 3400, open the clamping part at a predetermined position, and make the formed cigar blank fall from the specified position. Then the heat forming structures 3300 open the next clamping operation, and so on, to continuously and efficiently heat and form the cigar blank.

[0164] As an example, the variable-diameter cam assembly 3400 is configured to be able to expand and contract radially along the forming wheel disc 3100, and the cooperating part can open or close the clamping of the cigar blank as the variable-diameter cam assembly 3400 expands and contracts.

[0165] Based on the above structure, when an abnormal situation occurs, the variable-diameter cam assembly 3400 contracts to release the support of the cooperating part. At this time, the cooperating part linkage causes the clamping part of the heat forming structure 3300 to open, so as to avoid the situation that the heat forming structure 3300 heats and forms the cigar blank for a long time due to unexpected situations, causing the loss of the cigar blank.

[0166] As an example, the driving part 3500, the forming wheel disc 3100 and the electric slip ring 3200 are all assembled on the forming bracket 3600. The forming bracket 3600 is symmetrically arranged on both sides of the forming wheel disc 3100. The center position of the forming wheel disc 3100 is provided with a forming connecting shaft 3101, which is fixedly arranged between the two forming brackets 3600. The forming connecting shaft 3101 is respectively sleeved with a first bearing 3102 and a second bearing 3103 outside; the first bearing 3102 and the second bearing 3103 are separately arranged along the length direction of the forming connecting shaft 3101.

[0167] The forming wheel disc 3100 is connected with the forming connecting shaft 3101 through the first bearing 3102. The movable part of the variable-diameter cam assembly 3400 is connected with the forming connecting shaft 3101 through the second bearing 3103.

[0168] The driving part 3500 is connected with the forming wheel disc 3100. The electric slip ring 3200 is arranged at the end of the forming part and connected with the heat forming structure 3300 on the forming wheel disc 3100.

[0169] Based on the above structure, the forming connecting shaft 3101 provides support for the forming wheel disc 3100 and the variable-diameter cam assembly 3400, the forming wheel disc 3100 is connected with the forming connecting shaft 3101 through the first bearing 3102, so that the forming wheel disc 3100 can rotate freely relative to the forming connecting shaft 3101, the second bearing 3103 provides a basis for the lateral movement of the variable-diameter cam assembly 3400, when the variable-diameter cam assembly 3400 moves laterally, it will release the resistance to all the matching parts of the hot forming structure 3300, so that the hot forming structure 3300 is in an open state, the electric slip ring 3200 provides power supply for the hot forming structure 3300, and the driving part 3500 provides power for the forming wheel disc 3100.

[0170] As an example, the driving part 3500 can include a forming drive motor 3501, a forming drive tooth 3502, a forming driven tooth 3503, a forming transmission shaft 3504 and a forming output tooth 3505; the forming drive motor 3501 is arranged on the forming support 3600, the forming drive tooth 3502 is arranged on the forming drive motor 3501, the forming transmission shaft 3504 is arranged on the forming support 3600 through a transmission bearing 3509, the transmission bearing 3509 is fixed on the forming support 3600, the forming transmission shaft 3504 is arranged in the transmission bearing 3509, the forming driven tooth 3503 and the forming output tooth 3505 are arranged on both sides of the forming transmission shaft 3504 respectively, and the first transmission belt 3506 is arranged between the forming driven tooth 3503 and the forming drive tooth 3502.

[0171] The forming matching tooth 3507 can be arranged on the first bearing 3102, and the second transmission belt 3508 can be arranged between the forming matching tooth 3507 and the forming output tooth 3505.

[0172] Based on the above structure, the forming drive motor 3501 rotates to drive the forming drive tooth 3502 to rotate, the first transmission belt drives the forming driven tooth 3503 to rotate, the forming driven tooth 3503 drives the forming output tooth 3505 to rotate through the forming transmission shaft 3504, and finally the second transmission belt 3508 drives the forming matching tooth 3507 to rotate, so that the forming wheel disc 3100 rotates along the forming connecting shaft 3101.

[0173] As an example, the size of the forming driven tooth is not less than the size of the forming output tooth 3505, the size of the forming output tooth 3505 is not greater than the size of the forming driven tooth 3503, and the size of the forming output tooth 3505 is not greater than the size of the forming matching tooth 3507.

[0174] Based on the above structure, since the size of the forming driven wheel is larger than that of the forming output tooth 3505, the forming output tooth 3505 can drive the forming driven wheel slowly and with large force, and since the size of the forming output tooth 3505 is smaller than that of the forming driven tooth 3503, the forming output tooth 3505 can rotate faster and stably, and finally slowly and stably drive the forming wheel 3100 to rotate.

[0175] As an example, a first tensioning wheel 3601 for adjusting the first conveying belt can be arranged on the forming support 3600, and a second tensioning wheel 3602 for adjusting the second conveying belt 3508 can be arranged on the transmission bearing 3509. The output force of the overall transmission process can be adjusted through the first tensioning wheel 3601 and the second tensioning wheel 3602 to ensure the stability of the output.

[0176] As an example, the forming wheel 3100 can include forming arc plates 3104 and electric controls 3105; the forming arc plates 3104 are uniformly arranged along the circumferential position of the first bearing 3102 to form a circular structure, the electric controls 3105 are arranged in the forming arc plates 3104, and the electric controls 3105 are connected with the electric slip ring 3200 and the heat forming structure 3300 respectively; the heat forming structure 3300 is arranged on the end of the forming arc plate 3104 away from the first bearing 3102, and the heat forming structure 3300 connected with the forming arc plate 3104 is connected with the electric control 3105 on the forming arc plate 3104.

[0177] Based on the above structure, all heat forming structures 3300 are powered through the electric slip ring 3200 to ensure normal power supply during rotation. The electric slip ring 3200 is a prior art, and this part of the scheme is only a conventional call of the prior art, so it will not be described again. The entire forming wheel 3100 is dispersed into multiple structures through the forming arc plates 3104, and independent electric controls 3105 are arranged in each forming arc plate 3104, which can reduce the maintenance difficulty in the later stage, avoid excessive load pressure on the single line, and ensure the stability of the overall performance.

[0178] As an example, the variable-diameter cam assembly 3400 can include a mounting base plate 3401, a movable wheel plate 3402, a linkage 3403, and a power cylinder 3404; the mounting base plate 3401 is fixedly arranged on the forming connecting shaft 3101, the linkage 3403 is fixedly arranged on the second bearing 3103, the piston rod 3423 of the power cylinder 3404 is fixedly connected with the end of the forming connecting shaft 3101, and the cylinder body 3424 of the power cylinder 3404 is connected with the linkage 3403 through the linkage 3405; the second bearing 3103 can move along the length direction of the forming connecting shaft 3101 when being driven.

[0179] The mounting base plate 3401 is provided with a guide portion 3406 for guiding the movable wheel plate 3402, and the linkage member 3403 is provided with a hinged portion 3407 connected with the movable wheel plate 3402. When the power cylinder 3404 is actuated, the movable wheel plate 3402 can move along the direction of the guide portion 3406, so as to change the overall outer contour of the variable-diameter cam assembly 3400.

[0180] Based on the above structure, under normal circumstances, the power cylinder 3404 is actuated, the linkage member 3403 moves to the left, and the movable wheel plate 3402 moves along the direction of the guide portion 3406 under the action of the hinged portion, so that the entire variable-diameter cam assembly 3400 forms an open state, thereby resisting all the hot forming structures 3300. When a special situation occurs, such as power failure, the power cylinder 3404 loses pressure, at this time, all the hot forming structures 3300 resist the movable wheel plate 3402, forcing the entire movable wheel plate 3402 to shrink, so that the variable-diameter cam assembly 3400 forms a shrinkage state, and the shrinkage variable-diameter cam assembly 3400 will not resist the hot forming structure 3300, so as not to keep the hot forming structure 3300 in a clamped state.

[0181] As an example, the mounting base plate 3401 is a circular structure, and the structure of the mounting base plate 3401 is not greater than that of the variable-diameter cam assembly 3400 in the open state. The guide portion 3406 is uniformly provided as a plurality along the plate surface of the mounting base plate 3401.

[0182] The guide portion 3406 is specifically a guide plate, which is fixed on the mounting base plate 3401 by bolts, and the guide plate is provided with an arc-shaped groove 3408 on both sides; the arc-shaped groove 3408 is symmetrically arranged along the center position of the guide plate.

[0183] A sliding block 3409 can be arranged on the side surface of the movable wheel plate 3402 close to the mounting base plate 3401, and the sliding block 3409 is connected with the movable wheel plate 3402 by bolts. A guide cavity 3410 matched with the guide plate is arranged in the sliding block 3409, and convex strips 3411 matched with the arc-shaped groove 3408 are arranged on both sides of the sliding block 3409. The guide plate is clamped into the guide cavity 3410.

[0184] Based on the above structure, the movable wheel plate 3402 is connected with the guide plate through the guide cavity 3410, so that the movable wheel plate 3402 can move along the specified direction more stably and accurately when driven by the hinged portion 3407.

[0185] As an example, the linkage 3403 can include a linkage sleeve 3412, a hinged collar 3413, a power collar 3414, and a locking collar 3415; the linkage sleeve 3412 is arranged on the second bearing 3103, and a support protruding ring 3416 is arranged on the linkage sleeve 3412 close to the end of the mounting base plate 3401; the support protruding ring 3416 is arranged perpendicular to the surface of the linkage sleeve 3412, the hinged collar 3413 and the power collar 3414 are arranged between the support protruding ring 3416 and the locking collar 3415, and the locking collar 3415, the support protruding ring 3416, the hinged collar 3413, and the power collar 3414 are provided with connecting through holes at corresponding positions, and the hinged collar 3413 and the power collar 3414 are fixed on the linkage sleeve 3412 by bolts passing through the connecting through holes.

[0186] Based on the above structure, by connecting the locking collar 3415, the support protruding ring 3416, the hinged collar 3413, and the power collar 3414 as a whole, and at the same time the second bearing 3103 can move along the length direction of the shaped connecting shaft 3101, when the power cylinder 3404 acts, the power collar 3414 is driven to act, the whole locking collar 3415 is driven to move, the hinged collar 3413 which forms a fixed structure with the locking collar 3415 drives the hinged part 3407 to act, and finally the movable wheel plate 3402 moves along the radial direction of the mounting base plate 3401.

[0187] As an example, the hinged part 3407 can include a first hinged lug 3417, a second hinged lug 3418, and a hinged connecting rod 3419; the first hinged lug 3417 is arranged on the movable wheel plate 3402, the second hinged lug 3418 is arranged on the side wall of the hinged collar 3413, and the hinged connecting rod 3419 is hinged with the first hinged lug 3417 and the second hinged lug 3418 respectively.

[0188] Based on the above structure, when the hinged collar 3413 is pulled to move along the length direction of the shaped connecting shaft 3101, the second hinged lug 3418 will give the hinged connecting rod 3419 a pulling force obliquely forward, and the pulling force can be decomposed into the radial direction and the axial direction of the shaped connecting shaft 3101, so as to make the movable wheel plate 3402 move along the radial direction of the shaped connecting shaft 3101, and at the same time make the hinged collar 3413 move along the axial direction of the shaped connecting shaft 3101.

[0189] As an example, the second bearing 3103 is a linear bearing, and the second bearing 3103 can move along the length direction of the shaped connecting shaft 3101.

[0190] As an example, the power connecting plate 3420 is arranged on both sides of the power collar 3414, the linkage part 3405 can include a power rod 3421 and a guide cylinder 3422; the guide cylinder 3422 is connected with the forming support 3600, the power rod 3421 is coaxially sleeved in the guide cylinder 3422, one end of the guide rod is connected with the cylinder part 3424 of the power cylinder 3404, and the other end is connected with the power connecting plate 3420.

[0191] Based on the above structure, the power cylinder 3404 provides power for the entire variable-diameter cam assembly 3400, so that the linkage occurs between the movable wheel plate 3402, the linkage part 3403 and the second bearing 3103, and the change of the variable-diameter cam contour is completed.

[0192] As an example, the power cylinder 3404 can include a piston rod 3423, a cylinder part 3424 and a connecting side plate 3425; the cylinder part 3424 is provided with a piston cavity for accommodating the piston rod 3423, and the cylinder part 3424 is further provided with an inflation hole for inflating and deflating the piston cavity; the connecting side plate 3425 is arranged on the end of the cylinder part 3424 close to the forming support 3600, and the connecting side wall is connected with the power connecting plate 3420.

[0193] Based on the above structure, since the forming connecting shaft 3101 is fixed, the piston rod 3423 fixed thereto cannot move, when the cylinder is supplied with gas, the cylinder part 3424 will move relative to the piston rod 3423, and finally the movement of the cylinder part 3424 is realized, so as to drive the power rod 3421 to move, realizing the movement of the cylinder part 3424 as the power part.

[0194] As an example, the plate body of the movable wheel plate 3402 is respectively provided with a first engaging groove 3426 and a second engaging groove 3427; the first engaging groove 3426 is arranged on the side of the movable wheel plate 3402 provided with the first hinged lug 3417, and the second engaging groove 3427 is arranged on the end face of the movable wheel plate 3402 provided with the sliding block 3409, and the movable wheel plate 3402 is further provided with a positioning groove 3428 for limiting the sliding block 3409;

[0195] The depths of the first engaging groove 3426 and the second engaging groove 3427 are the same, and are half of the thickness of the movable wheel plate 3402; the end of the movable wheel plate 3402 provided with the first engaging groove 3426 is a first connecting end; the end provided with the second engaging groove 3427 is a second connecting end; between adjacent movable wheel plates 3402, the second connecting end cooperates with the first engaging groove 3426, and the first connecting end cooperates with the second engaging groove 3427.

[0196] Based on the above structure, since all the movable wheel plates 3402 will move along the radial direction of the forming connecting shaft 3101 under the driving of the power cylinder 3404, in order to avoid interference between adjacent movable wheel plates 3402 during movement, the first and second connecting grooves 3426 and 3427 are arranged to make the whole movement process smooth, and the second connecting end cooperates with the first connecting groove 3426 and the first connecting end cooperates with the second connecting groove 3427, so that an internal support circle can be formed when fully retracted, avoiding each structure exceeding the limit position and playing a certain safety function.

[0197] As an example, when all the movable wheel plates 3402 are in the open working position, the profiles of all the movable wheel plates 3402 combine a special-shaped support ring, which can include a first release position 3429, a first compression position 3430, a second release position 3431 and a second compression position 3432; the first release position 3429 is arranged near the bottom, the first compression position 3430 is arranged near the left side, the second release position 3431 is arranged near the top, and the second release position 3431 is arranged near the first compression position 3430, and the second compression position 3432 is arranged between the first release position 3429 and the second release position 3431.

[0198] Based on the above structure, the hot press forming assembly receives the cigar blank from the upstream from the left side, so that the first compression position 3430 is arranged at the left side, so that the cigar blank is clamped and heated for the first time, at this time, preforming is performed, and then reaches the position of the second release position 3431, at this time, the hot forming structure 3300 releases the cigar blank, but due to the rotating position, the structure of the hot forming structure 3300 can still support the hot press forming structure, after the first heating forming, the two ends form a certain forming structure, and then after release, due to the rotation of the forming wheel disc 3100, the cigar blank is adjusted, the heating part 3307 is adjusted to contact the surface of the cigar blank, and then enters the second compression position 3432 for long-time heating forming, and finally reaches the first release position 3429 to release the cigar blank, through the two forming structures, the end forming can be more perfect.

[0199] As an example, the heat forming structure 3300 can include a clamping linkage plate 3301, a clamping guide assembly 3302, a pressing connecting plate 3303, and a linkage clamping mechanism 3304; the pressing connecting plate 3303 is provided with a first through hole 3305 for the clamping guide assembly 3302 to pass through and a second through hole 3306 for the power end of the linkage clamping mechanism 3304 to pass through, the clamping guide assembly 3302 is arranged through the first through hole 3305 and connected with the clamping linkage plate 3301, the power end of the clamping linkage plate 3301 passes through the second through hole 3306 and is connected with the clamping linkage plate 3301, when the pressing connecting plate 3303 is fixed and the clamping linkage plate 3301 is driven, the clamping linkage plate 3301 can drive the power end of the linkage clamping mechanism 3304 to open and close the linkage clamping mechanism 3304, and the linkage clamping mechanism 3304 can be provided with a heating part 3307; the clamping guide assembly 3302 is provided with a spring structure 3308.

[0200] Based on the above structure, when the pressing connecting plate 3303 is fixed and the clamping linkage plate 3301 is subjected to an external force, the power end of the clamping linkage plate 3301 can be pushed to stretch and retract, the clamping guide assembly 3302 provides a guiding action for stretching and retracting, so that the clamping linkage plate 3301 can move more stably, the stretching and retracting of the power end of the clamping linkage plate 3301 can open or close the linkage clamping mechanism 3304, and finally realize clamping and heating of the end of the cigar embryo to heat form the end, and the spring structure 3308 in the clamping guide assembly 3302 can reset the clamping linkage plate 3301.

[0201] As an example, the matching part can be a needle roller bearing 3309, the needle roller bearing 3309 is fixed on the clamping linkage plate 3301 through a support frame 3310, and the needle roller bearing 3309 can be in contact with the outer contour of the variable-diameter cam.

[0202] Based on the above structure, under the action of the spring structure 3308, the needle roller bearing 3309 can move with the outer contour of the variable-diameter cam to realize opening or closing operation at a specified position, such as releasing the cigar embryo at the first release position 3429 and the second release position 3431, and clamping the cigar embryo at the first pressing position 3430 and the second pressing position 3432.

[0203] As an example, the clamping guide assembly 3302 can include a guide rod 3311, a guide bearing 3312, and a reset spring 3313; the guide bearings 3312 are arranged in pairs in the first through hole 3305, the guide rod 3311 is arranged in pairs in the guide bearings 3312, and the reset spring 3313 is arranged between the clamping linkage plate 3301 and the pressing connecting plate 3303. The guide bearing 3312 can be a high-temperature linear bearing.

[0204] Based on the above structure, the guide bearing 3312 is set as a linear bearing, which can facilitate the movement of the guide rod 3311 and make the movement more smooth. The reset spring 3313 can reset the linkage clamping mechanism 3304, facilitating the overall clamping action.

[0205] As an example, the linkage clamping mechanism 3304 can include a power plate 3314, a shaped clamping base 3315, a shaped clamping fixed seat 3316, and a shaped clamping movable seat 3317. The shaped clamping base 3315 is arranged on the side wall of the compression connecting plate 3303 away from the clamping linkage plate 3301. The shaped clamping base 3315 is provided with a third through hole 3318 matched with the second through hole 3306. The shaped clamping fixed seat is fixedly connected with the shaped clamping base 3315. The shaped clamping movable seat 3317 is matched and arranged on the shaped clamping fixed seat 3316. The shaped clamping movable seat 3317 is hinged with the shaped clamping movable seat 3317. The power plate 3314 is connected with the shaped clamping movable seat 3317 through a connecting lug 3319. Under the action of the power plate 3314, the shaped clamping movable seat 3317 can be driven to rotate around the hinge point of the shaped clamping base 3315. The heating part 3307 is arranged in the shaped clamping fixed seat 3316 and the shaped clamping movable seat 3317.

[0206] Based on the above structure, in the case that the clamping linkage plate 3301 is independently driven, it can simultaneously drive the power plate 3314 to move. The power plate 3314 can drive the shaped clamping movable seat 3317 to act, so as to clamp and heat the cigar embryo in the shaped clamping fixed seat 3316 and the shaped clamping movable seat 3317.

[0207] As an example, the power plate 3314 can include a plate body part 3320, a weight-reducing hole 3321, and a limiting protrusion 3322. The limiting protrusion 3322 is arranged on the plate body part 3320 near the end close to the clamping linkage plate 3301. The weight-reducing hole 3321 is uniformly arranged along the length direction of the plate body part 3320.

[0208] Based on the above structure, the limiting protrusion 3322 can limit the limit movement position of the power plate 3314, preventing the power plate 3314 from exceeding the limit position. The weight-reducing hole 3321 can reduce the overall mass, so as to make the overall trigger more flexible.

[0209] As an example, the connecting lug 3319 can include a main connecting plate 3323, an upper pulley 3324, and a lower pulley 3325. The upper end of the main connecting plate 3323 is in a sharp structure, and the lower end is in a straight line structure. The upper pulley 3324 is arranged on the upper end of the main connecting plate 3323, and the lower pulley 3325 is arranged on the lower end of the main connecting plate 3323. The main connecting plate 3323 is connected with the power plate 3314 through bolts.

[0210] The guiding embedded groove 3326 is provided on both sides of the forming clamping movable seat 3317, and includes a first guiding section 3337 and a second guiding section 3338. The first guiding section 3337 is arranged away from the forming clamping base 3315 and parallel to the contact surface of the forming clamping movable seat 3317 and the cigar blank. The second guiding section 3338 is arranged close to the forming clamping base 3315 and at a predetermined angle to the contact surface of the forming clamping movable seat 3317 and the cigar blank. The upper pulley 3324 is arranged in the guiding embedded groove 3326.

[0211] Based on the above structure, when the power plate 3314 moves, the connecting protruding plate 3319 moves reciprocally. When the upper pulley 3324 is located at the end of the second guiding section 3338, the forming clamping movable seat 3317 is in an unfolded state. When the upper pulley 3324 moves along the second guiding section 3338, the opening of the forming clamping movable seat 3317 gradually decreases. When the upper pulley 3324 is located in the first guiding section 3337, the forming clamping movable seat 3317 contacts with the forming clamping fixed seat 3316 to form a long circular heating cavity for the end of the cigar blank. When the upper pulley 3324 moves along the first guiding section 3337 to the limit position, the end of the power plate 3314 pushes the cigar blank to roll, so that the heating is more uniform, and finally the end of the cigar blank is shaped.

[0212] For example, the guiding through groove 3327 is arranged in the forming clamping fixed seat 3316, and the lower pulley 3325 is arranged at least two in the single-side guiding through groove 3327, and the lower pulleys 3325 at the matching positions on the adjacent connecting protruding plates 3319 are connected as a whole by the center connecting rod 3328.

[0213] Based on the above structure, when the lower pulley 3325 is arranged at least two in the single-side guiding through groove 3327, the stability of the single-side movement can be ensured. The lower pulleys 3325 at the matching positions on the adjacent connecting protruding plates 3319 are connected as a whole by the center connecting rod 3328, so that the stability of the movement of the adjacent side lower pulleys 3325 can be ensured, and the opening and closing of the entire forming clamping fixed seat 3316 and the forming clamping movable seat 3317 are more efficient and accurate.

[0214] As an example, a lifting limiting block 3329 is arranged on the side wall of the forming clamping base 3315 close to the guide rod 3311; the lifting limiting block 3329 is connected with the forming clamping base 3315 through a bolt, and an arc-shaped lifting section 3330 can be arranged on the end of the forming clamping base 3315 away from the compression connecting plate 3303; the size of the arc-shaped lifting section 3330 is not less than the distance between the forming clamping fixed seat 3316 and the forming clamping movable seat 3317 at the maximum opening degree at the current position.

[0215] Based on the above structure, since the cigar embryo may rotate when entering the clamping cavity, the position of the cigar embryo just entering the clamping cavity is limited by the lifting limiting block 3329, which avoids the contact between the cigar embryo and other parts, ensures the cleanliness of the cigar embryo, and makes the whole movement process more efficient.

[0216] As an example, the end of the power plate 3314 can be provided with a forming groove 3331; the structure of the forming groove 3331 is matched with the structure of the final forming of the cigar embryo, and the ends of the forming clamping fixed seat 3316 and the forming clamping movable seat 3317 away from the forming clamping base 3315 are provided with forming half grooves 3332; two forming half grooves 3332 are combined into a forming groove 3331; two forming grooves 3331 form a final forming cavity.

[0217] As an example, the forming groove 3331 is a semicircular table structure as a whole, and the contact surface of the forming clamping fixed seat 3316 and the forming clamping movable seat 3317 with the cigar embryo is also a slope structure.

[0218] Based on the above structure, through the special setting of the structure of the heating part 3307, the cigar embryo can be accurately heated and formed.

[0219] As an example, a forced contact wheel 3333 can also be arranged on the connecting lug plate 3319; a forced contact plate 3334 is arranged on the entire forming wheel disc 3100 close to the second release position 3431, and the forced contact wheel 3333 is in contact with the forced contact plate 3334.

[0220] Based on the above structure, the power plate 3314 can be forced to retreat through the forced contact plate 3334, so as to start the clamping cavity for forming the cigar embryo, thereby avoiding the damage of the cigar embryo due to the failure of the reset spring 3313.

[0221] As an example, a forming adapter disc 3335 is arranged on the entire forming wheel disc 3100 close to the first release position 3429, and the forming adapter disc 3335 is provided with a conveying belt 3336 at the bottom.

[0222] Based on the above structure, the forming transfer disc 3335 transfers the heated and formed cigar embryo to the conveying belt 3336, and finally the conveying belt 3336 is used for conveying outward, and the forming transfer disc 3335 is the prior art, which will not be described here.

[0223] The above merely provides the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
