[0040] Example 1

[0041] like Figures 1 to 16 As shown, the present invention provides a technical solution:

[0042] A hot pressing forming assembly for both ends of a cigar, which 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 unit 3500; the hot forming structure 3300 is evenly arranged along the circumferential position of the forming wheel disc 3100, the electric slip ring 3200 is connected to the hot forming structure 3300, the driving unit 3500 is connected to the forming wheel disc 3100 and can rotate the forming wheel disc 3100, and a matching portion that matches the variable diameter cam assembly 3400 is provided on the hot forming structure 3300, the matching portion is arranged around the variable diameter cam assembly 3400, and periodically opens or closes the clamping portion for the cigar embryo along the contour of the variable diameter cam assembly 3400.

[0043] Based on the above structure, the forming wheel 3100 obtains the cigar embryo from the upstream at the specified position, and clamps the cigar embryo through the clamping part. The electric slip ring 3200 supplies power to all the thermoforming structures 3300 on the forming wheel 3100, so that it can heat and form the end of the cigar embryo in the clamped state. The thermoforming structure 3300 moves along the outer contour of the variable diameter cam assembly 3400, opens the clamping part at a predetermined position, and makes the formed cigar embryo fall from the specified position. Then the thermoforming structure 3300 starts the next clamping operation, and so on and so forth, continuously and efficiently thermoforming the cigar embryo.

[0044] As an example, the variable diameter cam assembly 3400 is configured to be able to expand and contract radially along the shaping wheel 3100, and the matching portion can open or close the clamping of the cigar embryo as the variable diameter cam assembly 3400 expands and contracts.

[0045] Based on the above structure, when an abnormal situation occurs, the variable diameter cam assembly 3400 contracts and releases the support for the mating part. At this time, the mating part is linked to open the clamping part of the thermoforming structure 3300, thereby preventing the thermoforming structure 3300 from heating and molding the cigar embryos for a long time due to unexpected circumstances, resulting in the loss of the cigar embryos.

[0046] As an example, the driving part 3500, the molded wheel disc 3100 and the electric slip ring 3200 are all assembled on the molded bracket 3600, the molded bracket 3600 is symmetrically arranged on both sides of the molded wheel disc 3100, a molded connecting shaft 3101 is arranged at the center of the molded wheel disc 3100, the molded connecting shaft 3101 is fixedly arranged between the two molded brackets 3600, and the molded connecting shaft 3101 is respectively sleeved with a first bearing 3102 and a second bearing 3103; the first bearing 3102 and the second shaft are separately arranged along the length direction of the molded connecting shaft 3101;

[0047] The molded wheel disc 3100 is connected to the molded connecting shaft 3101 via a first bearing 3102 ; the movable portion of the variable diameter cam assembly 3400 is connected to the molded connecting shaft 3101 via a second bearing 3103 .

[0048] The driving part 3500 is connected to the forming wheel disc 3100 , and the electric slip ring 3200 is arranged at the end of the forming part and connected to the hot forming structure 3300 on the forming wheel disc 3100 .

[0049] Based on the above structure, the molded connecting shaft 3101 provides support for the molded wheel disc 3100 and the variable diameter cam assembly 3400, and the molded wheel disc 3100 is connected to the molded connecting shaft 3101 through the first bearing 3102, so that the molded wheel disc 3100 can rotate freely relative to the molded connecting shaft 3101, and 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 thermoforming structure 3300, so that the thermoforming structure 3300 is in an open state, the electric slip ring 3200 supplies power to the thermoforming structure 3300, and the driving unit 3500 provides power for the molded wheel disc 3100.

[0050] As an example, the driving unit 3500 may include a molding driving motor 3501, a molding driving tooth 3502, a molding driven tooth 3503, a molding transmission shaft 3504 and a molding output tooth 3505; the molding driving motor 3501 is arranged on the molding bracket 3600, the molding driving tooth 3502 is arranged on the molding driving motor 3501, the molding transmission shaft 3504 is arranged on the molding bracket 3600 through a transmission bearing 3509, the transmission bearing 3509 is fixed on the molding bracket 3600, the molding transmission shaft 3504 is arranged in the transmission bearing 3509, the molding driven tooth 3503 and the molding output tooth 3505 are respectively arranged on both sides of the molding transmission shaft 3504, and a first transmission belt 3506 is arranged between the molding driven tooth 3503 and the molding driving tooth 3502;

[0051] A molded mating tooth 3507 may be provided on the first bearing 3102 , and a second conveyor belt 3508 may be provided between the molded mating tooth 3507 and the molded output tooth 3505 .

[0052] Based on the above structure, the molding drive motor 3501 rotates to drive the molding drive tooth 3502 to rotate, and the molding driven tooth 3503 is driven to rotate through the first conveyor belt. The molding driven tooth 3503 drives the molding output tooth 3505 to rotate through the molding transmission shaft 3504, and finally the molding matching tooth 3507 is driven to rotate through the second conveyor belt 3508, so that the molding wheel 3100 rotates along the molding connecting shaft 3101.

[0053] As an example, the size of the formed driven wheel is not less than the size of the formed output tooth 3505, the size of the formed output tooth 3505 is not greater than the size of the formed driven tooth 3503, and the size of the formed output tooth 3505 is not greater than the size of the formed mating tooth 3507.

[0054] Based on the above structure, since the size of the formed driven wheel is larger than the size of the formed output tooth 3505, the formed output tooth 3505 can drive the formed driven wheel slowly and with greater force. At the same time, since the size of the formed output tooth 3505 is smaller than the size of the formed driven tooth 3503, the formed output tooth 3505 can rotate faster and more steadily, and finally drive the formed wheel disc 3100 to rotate slowly and steadily.

[0055] As an example, a first tensioning wheel 3601 for adjusting the first conveyor belt may be provided on the forming bracket 3600, and a second tensioning wheel 3602 for adjusting the second conveyor belt 3508 may be provided on the transmission bearing 3509. The output force of the overall transmission process can be adjusted by the first tensioning wheel 3601 and the second tensioning wheel 3602 to ensure the stability of the output.

[0056] As an example, the molded wheel 3100 may include a molded arc plate 3104 and an electric control unit 3105; the molded arc plate 3104 is evenly arranged along the circumferential position of the first bearing 3102 to form a circular structure, the electric control unit 3105 is arranged in the molded arc plate 3104, and the electric control unit 3105 is respectively connected to the electric slip ring 3200 and the thermoformed structure 3300; the thermoformed structure 3300 is arranged on the end of the molded arc plate 3104 away from the first bearing 3102, and the thermoformed structure 3300 connected to the molded arc plate 3104 is connected to the electric control unit 3105 on the molded arc plate 3104 where it is located.

[0057] Based on the above structure, all the hot forming structures 3300 are powered by the electric slip ring 3200 to ensure the normal supply of electricity during rotation. The electric slip ring 3200 is a prior art, and this solution is only a conventional call of the prior art, so it will not be repeated again. The entire forming wheel disc 3100 is dispersed into a multi-piece structure through the forming arc plate 3104, and an independent electrical control unit 3105 is set in each forming arc plate 3104. On the one hand, it can reduce the difficulty of later maintenance, and on the other hand, it also avoids excessive load pressure on a single line, thereby ensuring the stability of the overall performance.

[0058] As an example, the variable diameter cam assembly 3400 may include a mounting base 3401, a movable wheel plate 3402, a linkage member 3403 and a power cylinder 3404; the mounting base 3401 is fixedly disposed on the formed connecting shaft 3101, the linkage member 3403 is fixedly disposed on the second bearing 3103, the piston rod 3423 of the power cylinder 3404 is fixedly connected to the end of the formed connecting shaft 3101, and the cylinder body 3424 of the power cylinder 3404 is connected to the linkage member 3403 through the linkage member 3405; when the second bearing 3103 is driven, it can move along the length direction of the formed connecting shaft 3101.

[0059] A guide portion 3406 for guiding the movable wheel plate 3402 is provided on the mounting base plate 3401, and a hinge portion 3407 connected to the movable wheel plate 3402 is provided on the linkage member 3403. When the power cylinder 3404 is actuated, the movable wheel plate 3402 can move along the direction of the guide portion 3406, thereby realizing the change of the overall outer contour of the variable diameter cam assembly 3400.

[0060] Based on the above structure, under normal circumstances, the power cylinder 3404 is actuated, the linkage part 3403 moves to the left, and the movable wheel plate 3402 moves along the direction of the guide part 3406 under the action of the hinge, so that the entire variable diameter cam assembly 3400 is in an open state, thereby resisting all the thermoforming structures 3300; when special circumstances occur, such as power failure, the power cylinder 3404 loses pressure, and at this time all the thermoforming 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 is in a contracted state, and the contracted variable diameter cam assembly 3400 will not resist the thermoforming structure 3300, and will not keep it in a clamped state.

[0061] As an example, the mounting substrate 3401 is a circular structure, and the structure of the mounting substrate 3401 is no larger than when the variable diameter cam assembly 3400 is in an open state. A plurality of guide portions 3406 are evenly arranged along the plate surface of the mounting substrate 3401 .

[0062] The guide portion 3406 is specifically a guide plate, which is fixed to the mounting base plate 3401 by bolts. Arc grooves 3408 are arranged on both sides of the guide plate; the arc grooves 3408 are symmetrically arranged along the center position of the guide plate.

[0063] A sliding block 3409 can be arranged on the side of the movable wheel plate 3402 close to the mounting base plate 3401. The sliding block 3409 is connected to the movable wheel plate 3402 by bolts. A guide cavity 3410 cooperating with the guide plate is arranged in the sliding block 3409. Raised strips 3411 cooperating with the arc groove 3408 are arranged on both sides of the sliding block 3409, and the guide plate is inserted into the guide cavity 3410.

[0064] Based on the above structure, the movable wheel plate 3402 is connected to the guide plate through the guide cavity 3410, so that the movable wheel plate 3402 can move more stably and accurately along the specified direction when driven by the hinge part 3407.

[0065] As an example, the linkage part 3403 may include a linkage sleeve 3412, an articulated ring 3413, a power ring 3414 and a locking ring 3415; the linkage sleeve 3412 is arranged on the second bearing 3103, and a supporting protrusion 3416 is arranged on the end of the linkage sleeve 3412 close to the mounting base plate 3401; the supporting protrusion 3416 is arranged perpendicular to the surface of the linkage sleeve 3412, and the articulated ring 3413 and the power ring 3414 are arranged between the supporting protrusion 3416 and the locking ring 3415, and corresponding positions on the locking ring 3415, the support protrusion 3416, the articulated ring 3413 and the power ring 3414 are provided with connecting through holes, and the articulated ring 3413 and the power ring 3414 are fixed to the linkage sleeve 3412 by bolts passing through the connecting through holes.

[0066] Based on the above structure, the locking ring 3415, the supporting convex ring 3416, the hinged ring 3413 and the power ring 3414 are connected as a whole, and the second bearing 3103 can move along the length direction of the formed connecting shaft 3101. When the power cylinder 3404 is actuated, the power ring 3414 is driven to move, so that the entire locking ring 3415 moves, and the hinged ring 3413 forming a fixed structure therewith drives the hinged part 3407 to move, and finally the movable wheel plate 3402 is moved radially along the mounting base plate 3401.

[0067] As an example, the hinge portion 3407 may include a first hinge ear 3417, a second hinge ear 3418 and a hinge connecting rod 3419; the first hinge ear 3417 is arranged on the movable wheel plate 3402, the second hinge ear 3418 is arranged on the side wall of the hinge collar 3413, and the hinge connecting rod 3419 is hinged to the first hinge ear 3417 and the second hinge ear 3418 respectively;

[0068] Based on the above structure, when the articulated ring 3413 is pulled to move in the length direction of the formed connecting shaft 3101, the second articulated ear 3418 will give the articulated link 3419 a pulling force obliquely forward, and the pulling force can be decomposed into radial and axial directions along the formed connecting shaft 3101, thereby causing the movable wheel plate 3402 to move radially along the formed connecting shaft 3101 and causing the articulated ring 3413 to move axially along the formed connecting shaft 3101.

[0069] As an example, the second bearing 3103 is a linear bearing, and the second bearing 3103 can move along the long direction of the molded connecting shaft 3101.

[0070] As an example, power connecting plates 3420 are provided on both sides of the power ring 3414, and the linkage part 3405 may include a power rod 3421 and a guide cylinder 3422; the guide cylinder 3422 is connected to the forming bracket 3600, and the power rod 3421 is coaxially sleeved in the guide cylinder 3422, one end of the guide rod is connected to the cylinder body 3424 of the power cylinder 3404, and the other end is connected to the power connecting plate 3420.

[0071] Based on the above structure, the power cylinder 3404 provides power to the entire variable diameter cam assembly 3400, so that the movable wheel plate 3402, the linkage member 3403 and the second bearing 3103 are linked to complete the change of the variable diameter cam profile.

[0072] As an example, the power cylinder 3404 may include a piston rod 3423, a cylinder body 3424 and a connecting side plate 3425; a piston chamber for accommodating the piston rod 3423 is provided in the cylinder body 3424, and an inflation hole for inflating and deflating the piston chamber is also provided on the cylinder body 3424; the connecting side plate 3425 is provided on the end of the cylinder body 3424 close to the forming bracket 3600, and the connecting side wall is connected to the power connecting plate 3420.

[0073] Based on the above structure, since the molded connecting shaft 3101 is fixed, the piston rod 3423 fixed thereto cannot move. When gas is supplied to the cylinder, the cylinder body 3424 will move relative to the piston rod 3423, and finally the cylinder body 3424 will move, thereby driving the power rod 3421 to move, and realizing the movement with the cylinder body 3424 as the power unit.

[0074] 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 provided on the side of the movable wheel plate 3402 provided with the first hinge ear 3417, and the second engaging groove 3427 is provided on the end surface of the movable wheel plate 3402 provided with the sliding block 3409, and a positioning groove 3428 for limiting the sliding block 3409 is also provided on the movable wheel plate 3402;

[0075] The depths of the first connecting groove 3426 and the second connecting groove 3427 are set to be the same, both of which are half the thickness of the movable wheel plate 3402; the end of the movable wheel plate 3402 provided with the first connecting groove 3426 is the first connecting end; the end provided with the second connecting groove 3427 is the second connecting end; between adjacent movable wheel plates 3402, the second connecting end cooperates with the first connecting groove 3426, and the first connecting end cooperates with the second connecting groove 3427.

[0076] Based on the above structure, since all the movable wheel plates 3402 will move radially along the formed connecting shaft 3101 under the drive of the power cylinder 3404, in order to avoid interference between adjacent movable wheel plates 3402 during movement, a first connecting groove 3426 and a second connecting groove 3427 are set to make the entire movement process smooth. At the same time, the second connecting end cooperates with the first connecting groove 3426, and the first connecting end cooperates with the second connecting groove 3427, so as to form an internal support circle when fully retracted, thereby preventing each structure from exceeding the limit position and playing a certain safety function.

[0077] As an example, when all the movable wheel plates 3402 are in the open working position, the contours of all the movable wheel plates 3402 are combined into a special-shaped support ring, which may include a first release position 3429, a first clamping position 3430, a second release position 3431 and a second clamping position 3432; the first release position 3429 is set close to the bottom, the first clamping position 3430 is set close to the left position, the second release position 3431 is set close to the top, and the second release position 3431 is set close to the first clamping position 3430, and the second clamping position 3432 is set between the first release position 3429 and the second release position 3431.

[0078] Based on the above structure, the hot pressing molding component receives the cigar embryos from the upstream from the left side, so the first pressing position 3430 is set at the left side, so that the cigar embryos are clamped and heat-formed for the first time. At this time, pre-forming is carried out, and then it will reach the second releasing position 3431. At this time, the thermoforming structure 3300 releases the cigar embryos, but due to the rotating position, the structure of the thermoforming structure 3300 can still support the thermoforming structure. After the first heating and molding, a certain molding structure is formed at both ends, and then after release, due to the rotation of the molding wheel 3100, the cigar embryos will have a fine adjustment, adjusting the contact surface between the heating part 3307 and the cigar embryo, and then enter the second pressing position 3432 for a longer time of heating and molding, and finally reach the first releasing position 3429 to release the cigar embryo. Through the two molding structures, the end can be molded more perfectly.

[0079] As an example, the thermoforming structure 3300 may include a clamping linkage plate 3301, a clamping guide assembly 3302, a clamping connection plate 3303 and a linkage clamping mechanism 3304; the clamping connection 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 connected to the clamping linkage plate 3301 through the first through hole 3305. The power end of the clamping linkage plate 3301 passes through the second through hole 3306 and is connected to the clamping linkage plate 3301. When the clamping 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. A heating part 3307 can be provided in the linkage clamping mechanism 3304; a spring structure 3308 is provided in the clamping guide assembly 3302.

[0080] Based on the above structure, when the clamping connecting plate 3303 is fixed and the clamping linkage plate 3301 is subjected to external force, it can push the power end of the clamping linkage plate 3301 to retract and retract. The clamping guide assembly 3302 provides a guide for the retraction and retraction, so that it can move more stably. The retraction and retraction of the power end of the clamping linkage plate 3301 can open or close the linkage clamping mechanism 3304, and finally achieve the clamping and heating of the end of the cigar embryo, so that the end is thermoformed. The spring structure 3308 is set in the clamping guide assembly 3302 so that the clamping linkage plate 3301 can be reset.

[0081] As an example, the mating portion may be a needle bearing 3309 , which is fixed to the clamping linkage plate 3301 via a support frame 3310 , and the needle bearing 3309 can abut against the outer contour of the variable diameter cam.

[0082] Based on the above structure, under the action of the spring structure 3308, the needle bearing 3309 can move along the outer contour of the variable diameter cam to achieve the opening or closing operation of the 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 clamping position 3430 and the second clamping position 3432.

[0083] As an example, the clamping guide assembly 3302 may include a guide rod 3311, a guide bearing 3312 and a return spring 3313; the guide bearings 3312 are arranged in pairs in the first through holes 3305, the guide rods 3311 are sleeved in pairs in the guide bearings 3312, and the return spring 3313 is arranged between the clamping linkage plate 3301 and the clamping connection plate 3303. The guide bearing 3312 may be a high-temperature linear bearing.

[0084] 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 its movement smoother. The reset spring 3313 can reset the linkage clamping mechanism 3304 to facilitate the overall clamping action.

[0085] As an example, the linkage clamping mechanism 3304 may include a power plate 3314, a molded clamping base 3315, a molded clamping fixed seat 3316 and a molded clamping movable seat 3317. The molded clamping base 3315 is arranged on the side wall of the clamping connecting plate 3303 away from the clamping linkage plate 3301. The molded clamping base 3315 is provided with a third through hole 3318 for cooperating with the second through hole 3306. The molded fixed clamping seat is fixedly connected to the molded clamping base 3315. The movable seat 3317 is matchedly arranged on the molding clamping fixed seat 3316, and the molding clamping movable seat 3317 is hinged to the molding clamping movable seat 3317; the power plate 3314 is connected to the molding clamping movable seat 3317 through the connecting convex plate 3319. Under the action of the power plate 3314, the molding clamping movable seat 3317 can be driven to rotate around the hinge point of the molding clamping base 3315. The heating part 3307 is arranged in the molding clamping fixed seat 3316 and the molding clamping movable seat 3317.

[0086] Based on the above structure, when the clamping linkage plate 3301 is driven independently, it can synchronously drive the power plate 3314 to move, and the power plate 3314 can drive the forming clamping movable seat 3317 to move, so as to clamp and heat the cigar embryos entering into the forming clamping fixed seat 3316 and the forming clamping movable seat 3317.

[0087] As an example, the power plate 3314 may include a plate body 3320, a weight-reducing hole 3321 and a limiting ridge 3322; the limiting ridge 3322 is arranged on the plate body 3320 near the end of the clamping linkage plate 3301, and the weight-reducing hole 3321 is evenly arranged along the length direction of the plate body 3320.

[0088] Based on the above structure, the limiting ridge 3322 can be used to limit the extreme movement position of the power plate 3314 to prevent the power plate 3314 from exceeding the extreme position. The weight-reducing hole 3321 can reduce the overall mass, thereby making the overall triggering more flexible.

[0089] As an example, the connecting protrusion 3319 may 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 a sharp structure, and the lower end is a straight structure, the upper pulley 3324 is arranged at the upper end of the main connecting plate 3323, and the lower pulley 3325 is arranged at the lower end of the main connecting plate 3323; the main connecting plate 3323 is connected to the power plate 3314 by bolts.

[0090] Guide embedding grooves 3326 are provided on both side walls of the forming and clamping movable seat 3317; the guide embedding grooves 3326 include a first guide section 3337 and a second guide section 3338; ​​the first guide section 3337 is arranged away from the forming and clamping base 3315, and the first guide section 3337 and the contact surface of the forming and clamping movable seat 3317 and the cigar embryo are arranged in parallel, the second guide section 3338 is arranged close to the forming and clamping base 3315, and the second guide section 3338 and the contact surface of the forming and clamping movable seat 3317 and the cigar embryo are arranged at a predetermined angle, and the upper pulleys 3324 are respectively arranged in the guide embedding grooves 3326.

[0091] Based on the above structure, when the power plate 3314 is in motion, it can drive the connecting convex plate 3319 to perform reciprocating motion. When the upper pulley 3324 is located at the end of the second guide section 3338, the forming and clamping movable seat 3317 is in an expanded state. When the upper pulley 3324 gradually moves along the direction of the second guide section 3338, the opening of the forming and clamping movable seat 3317 gradually decreases. When the upper pulley 3324 is located in the first guide section 3337, the forming and clamping movable seat 3317 contacts the forming and clamping fixed seat 3316 to form an oblong heating cavity for the end of the cigar embryo. When the upper pulley 3324 moves to the extreme position along the first guide section 3337, the heating cavity gradually shrinks. During the shrinkage of the heating cavity, the end of the power plate 3314 will push the cigar embryo to roll, making the heating more uniform, and finally forming the end of the cigar embryo.

[0092] As an example, a guide groove 3327 is provided in the molding clamping fixing seat 3316, at least two lower pulleys 3325 are provided in the single-side guide groove 3327, and the lower pulleys 3325 at matching positions on adjacent connecting protrusions 3319 are connected as a whole through a central connecting rod 3328.

[0093] Based on the above structure, at least two lower pulleys 3325 are set in the single-side guide groove 3327 to ensure the stability of single-sided movement. The lower pulleys 3325 at matching positions on adjacent connecting protrusions 3319 are usually connected as a whole through a central connecting rod 3328 to ensure the stability of the movement of the lower pulleys 3325 on the adjacent sides, making the opening and closing of the entire molding clamping fixed seat 3316 and the molding clamping movable seat 3317 more efficient and precise.

[0094] As an example, a lifting limit block 3329 is provided on the side wall of the forming clamping base 3315 close to the guide rod 3311; the lifting limit block 3329 is connected to the forming clamping base 3315 by bolts, and an arc-shaped lifting section 3330 can be provided on the end of the forming clamping base 3315 away from the clamping 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 in the current position.

[0095] Based on the above structure, since the cigar embryo may rotate when entering the clamping cavity, the lifting limit block 3329 is used to limit the position of the cigar embryo just entering the clamping cavity to prevent the cigar embryo from contacting other parts, thereby ensuring the cleanliness of the cigar embryo and making the entire movement process more efficient.

[0096] As an example, a molding groove 3331 may be provided at the end of the power plate 3314; the structure of the molding groove 3331 is adapted to the structure of the final molding of the cigar embryo, and a molding half-groove 3332 is provided on the ends of the molding clamping fixed seat 3316 and the molding clamping movable seat 3317 away from the molding clamping base 3315; the two molding half-grooves 3332 are combined into a molding groove 3331; and the two molding grooves 3331 form the final molding cavity.

[0097] As an example, the molding groove 3331 is a semi-conical structure as a whole, and the contact surfaces between the molding clamping fixed seat 3316 and the molding clamping movable seat 3317 and the cigar embryo are also inclined plate structures.

[0098] Based on the above structure, the cigar embryo can be accurately heated and formed by the special setting of the heating part 3307 structure.

[0099] As an example, a forced resistance wheel 3333 may be further provided on the connecting protruding plate 3319 ; a forced resistance plate 3334 is provided at a position close to the second release position 3431 on the entire forming wheel disc 3100 , and the forced resistance wheel 3333 is in contact with the forced resistance plate 3334 .

[0100] Based on the above structure, the power plate 3314 can be forced to retreat by the forced resistance plate 3334, so as to start the clamping cavity for molding the cigar embryo, thereby avoiding the damage of the cigar embryo due to the failure of the reset spring 3313.

[0101] As an example, a forming transfer disc 3335 is provided on the entire forming wheel disc 3100 at a position close to the first release position 3429 , and a conveyor belt 3336 is provided at the bottom of the forming transfer disc 3335 .

[0102] Based on the above structure, the forming transfer plate 3335 transfers the heated and formed cigar embryos to the conveyor belt 3336, and finally transports them outward through the conveyor belt 3336. The forming transfer plate 3335 is a prior art and will not be described in detail here.

[0103] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
