[0040] Embodiment 1

[0041] As Figures 7-11 shown, the present application provides a technical scheme:

[0044] Based on the above structure, under normal circumstances, the power cylinder 3404 acts, the linkage 3403 moves to the left, the movable wheel plate 3402 moves along the direction of the guide part 3406 under the action of the hinge part, so that the whole 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 whole movable wheel plate 3402 to shrink, so that the variable diameter cam assembly 3400 forms a shrinking state, and the shrinking variable diameter cam assembly 3400 will not resist the hot forming structure 3300, so it will not keep the clamping state.

[0045] As an example, the mounting substrate 3401 is a circular structure, and the structure of the mounting substrate 3401 is not greater than that of the variable diameter cam assembly 3400 in the open state. The guide part 3406 is uniformly provided with a plurality of guide plates along the surface of the mounting substrate 3401.

[0046] The guide part 3406 is a guide plate, which is fixed on the mounting substrate 3401 by bolts, and arc-shaped grooves 3408 are provided on both sides of the guide plate; the arc-shaped grooves 3408 are symmetrically arranged along the center position of the guide plate.

[0047] A sliding block 3409 can be provided on the side of the movable wheel plate 3402 close to the mounting substrate 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 grooves 3408 are arranged on both sides of the sliding block 3409. The guide plate is clamped into the guide cavity 3410.

[0048] 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 more stably and accurately in the specified direction when driven by the hinge part 3407.

[0049] As an example, the linkage 3403 can include a linkage sleeve 3412, a hinge sleeve ring 3413, a power sleeve ring 3414 and a locking sleeve ring 3415; the linkage sleeve 3412 is arranged on the second bearing 3103, and a support convex ring 3416 is arranged on the end of the linkage sleeve 3412 close to the mounting substrate 3401; the support convex ring 3416 is arranged perpendicular to the surface of the linkage sleeve 3412, the hinge sleeve ring 3413 and the power sleeve ring 3414 are arranged between the support convex ring 3416 and the locking sleeve ring 3415, and the locking sleeve ring 3415, the support convex ring 3416, the hinge sleeve ring 3413 and the power sleeve ring 3414 are provided with connecting through holes at corresponding positions, and the hinge sleeve ring 3413 and the power sleeve ring 3414 are fixed on the linkage sleeve 3412 by bolts penetrating through the connecting through holes.

[0050] Based on the above structure, by connecting the locking collar 3415, the supporting convex ring 3416, the hinged collar 3413 and the power collar 3414 as a whole, while the second bearing 3103 can move along the length direction of the shaped connecting shaft 3101, when the power cylinder 3404 acts, it drives the power collar 3414 to act, so that the whole locking collar 3415 moves, and the hinged collar 3413 which forms a fixed structure with it drives the hinged part 3407 to act, and finally realizes the movement of the movable wheel plate 3402 along the radial direction of the installation base plate 3401.

[0051] As an example, the hinged part 3407 can include a first hinged ear 3417, a second hinged ear 3418 and a hinged connecting rod 3419; the first hinged ear 3417 is arranged on the movable wheel plate 3402, the second hinged ear 3418 is arranged on the side wall of the hinged collar 3413, and the hinged connecting rod 3419 is hinged with the first hinged ear 3417 and the second hinged ear 3418 respectively;

[0052] Based on the above structure, when the hinged collar 3413 is pulled to move in the length direction of the shaped connecting shaft 3101, the second hinged ear 3418 will give the hinged connecting rod 3419 a forward oblique pulling force, 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.

[0053] 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.

[0054] As an example, the power collar 3414 is provided with a power connecting plate 3420 on both sides, and the linkage part 3405 can include a power rod 3421 and a guide cylinder 3422; the guide cylinder 3422 is connected with the shaped 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.

[0055] Based on the above structure, the power cylinder 3404 provides power for the whole variable diameter cam assembly 3400, so that 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.

[0056] As an example, the power cylinder 3404 can include a piston rod 3423, a cylinder body 3424, and a connecting side plate 3425; the cylinder body 3424 is provided with a piston cavity for accommodating the piston rod 3423, and the cylinder body 3424 is also provided with a charging hole for charging and discharging the piston cavity; the connecting side plate 3425 is arranged on the end of the cylinder body 3424 close to the forming support 3600, and the connecting side plate is connected with the power connecting plate 3420.

[0057] Based on the above structure, since the forming connecting shaft 3101 is fixed, the piston rod 3423 fixed thereto cannot move, and when the cylinder is supplied with gas, the cylinder body 3424 will move relative to the piston rod 3423, and finally the movement of the cylinder body 3424 is realized, thereby driving the power rod 3421 to move, realizing the movement of the cylinder body 3424 as a power part.

[0058] 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 also provided with a positioning groove 3428 for limiting the sliding block 3409;

[0059] 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.

[0060] 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 engaging groove 3426 and the second engaging groove 3427 are arranged, so that the whole movement process is smooth, and the second connecting end cooperates with the first engaging groove 3426, and the first connecting end cooperates with the second engaging groove 3427, so that an internal supporting circle can be formed when completely retracted, avoiding that each structure exceeds the limit position, and playing a certain safety function.

[0061] 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 combine a special-shaped supporting ring, which can include a first release position 3429, a first pressing position 3430, a second release position 3431 and a second pressing position 3432; the first release position 3429 is arranged near the bottom, the first pressing 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 pressing position 3430, and the second pressing position 3432 is arranged between the first release position 3429 and the second release position 3431.

[0062] 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 pressing 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 are released, due to the rotation of the forming wheel disc 3100, the cigar blank is adjusted, the contact surface between the heating part 3307 and the cigar blank is adjusted, and then enters the second pressing 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.

[0063] Embodiment 2

[0064] As shown in the technical scheme, Figures 1-16 The utility model provides a technical scheme:

[0065] A hot forming structure for a cigar end, 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 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 arranged circumferentially 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.

[0066] 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 then the heat forming structures 3300 open the next clamping operation. In this way, the cigar blank can be continuously and efficiently heat formed.

[0067] 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.

[0068] 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 is linked to open the clamping part of the heat forming structure 3300, 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 circumstances, causing the loss of the cigar blank.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] The first bearing 3102 can be provided with a forming matching tooth 3507, and the forming matching tooth 3507 and the forming output tooth 3505 can be provided with a second transmission belt 3508.

[0075] 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.

[0076] 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.

[0077] Based on the above structure, since the size of the forming driven wheel is larger than the size 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 the size 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.

[0078] 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.

[0079] 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.

[0080] Based on the above structure, all heat forming structures 3300 are powered by 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 by the forming arc plates 3104, and independent electric controls 3105 are arranged in each forming arc plate 3104. On the one hand, this can reduce the difficulty of later maintenance, and on the other hand, it also avoids excessive load pressure on the separate line to ensure the stability of the overall performance.

[0081] 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 driven.

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.

[0083] 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.

[0084] For 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.

[0085] The guide portion 3406 is specifically a guide plate, which is fixed on the mounting base plate 3401 by bolts, and 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.

[0086] 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 a convex strip 3411 matched with the arc-shaped groove 3408 is arranged on both sides of the sliding block 3409. The guide plate is clamped into the guide cavity 3410.

[0087] 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 more stably and accurately along the specified direction when driven by the hinged portion 3407.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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;

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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, 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, then after release, due to the rotation of the forming wheel disc 3100, the cigar blank has a fine adjustment, the adjustment heating part 3307 adjusts the contact surface of the cigar blank, then enters the second compression position 3432 for a long time of 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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 arranged on the shaped clamping fixed seat 3316, and 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.

[0109] Based on the above structure, in the case that the clamping linkage plate 3301 is independently driven, it can synchronously drive the power plate 3314 to move, and 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] Based on the above structure, the power plate 3314 can drive the connecting lug 3319 to reciprocate when the power plate 3314 is in action. 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 gradually 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 is in contact with the forming clamping fixed seat 3316 to form an oblong 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.

[0115] 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-sided guiding through groove 3327, and the lower pulleys 3325 at the matching positions on the adjacent connecting lugs 3319 are connected as a whole by the center connecting rod 3328.

[0116] Based on the above structure, the lower pulley 3325 is arranged at least two in the single-sided guiding through groove 3327, which can ensure the stability of the single-sided movement. The lower pulleys 3325 at the matching positions on the adjacent connecting lugs 3319 are usually connected as a whole by the center connecting rod 3328, which can ensure the stability of the movement of the adjacent side lower pulleys 3325, so that the opening and closing of the entire forming clamping fixed seat 3316 and the forming clamping movable seat 3317 are more efficient and accurate.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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 inclined plate structure.

[0121] 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.

[0122] 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.

[0123] Based on the above structure, the forced contact plate 3334 can forcibly make the power plate 3314 retreat, so as to start the clamping cavity for forming the cigar embryo, and avoid the damage of the cigar embryo due to the failure of the reset spring 3313.

[0124] 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.

[0125] 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.

[0126] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
