In addition, the linear driving mechanism is arranged, so that the clamping jaw mechanism can be opened at any specified position within a specified range, and accurate feeding and discharging of cigars of different lengths can be realized.

[0049] Please refer to Figures 1 to 6 The present embodiment provides a rolling device 100, which is used to roll an outer wrapping member on an outer surface of an inner embryo. Specifically, in an embodiment, the rolling device 100 is a stepless speed regulation cigar rolling device, which is used to roll a cigar wrapper on an outer surface of an inner embryo cigar.

[0050] The rolling device 100 comprises a rack 10, a rolling mechanism 20, a first stepless speed regulation driving mechanism 30, a second stepless speed regulation driving mechanism 40, and a linear driving mechanism 50. The rolling mechanism 20 is arranged on the rack 10 and is used to roll the outer wrapping piece on the outer surface of the inner embryo. The first stepless speed regulation driving mechanism 30 is arranged on the rack 10 and is connected with the rolling mechanism 20, and is used to drive the components in the rolling mechanism 20 to open and close. The second stepless speed regulation driving mechanism 40 is arranged on the rack 10 and is connected with the roller pressing unit 22 in the rolling mechanism 20, and is used to drive the roller pressing unit 22 to rotate.

That is, the linear driving mechanism 50 is used to cooperate with the jaw mechanism to realize the feeding and discharging process of the jaw mechanism at the front end.

[0051] It can be understood that the rolling device in the prior art has a single function, and a single rolling device can only adapt to the production of one specification of cigar. According to the rolling principle of cigar, the rolling speed of cigar is different for different lengths, so the existing rolling device cannot realize the cigar cover rolling of cigars of different specifications, which leads to the need to equip different specifications of rolling devices for cigars of different lengths, thereby causing high manufacturing cost.

[0052] The rolling device 100 provided in the embodiment adopts the first stepless speed regulation driving mechanism 30 and the second stepless speed regulation driving mechanism 40, so that the required rolling speed can be selected according to actual needs during production, and one rolling device 100 can adapt to the rolling production of cigars of different specifications and lengths, so that the manufacturing cost can be better reduced. The linear driving mechanism 50 is further arranged, and the linear driving mechanism 50 cooperates with the jaw mechanism, so that the jaw mechanism can be opened at any specified position within a specified range, so that the feeding and discharging of cigars of different lengths can be accurately realized.

[0053] Specifically, in one embodiment, the first stepless speed regulation driving mechanism 30 and the second stepless speed regulation driving mechanism 40 are controlled by an open motion control system based on MP3300 to realize electronic stepless speed regulation.

[0054] Specifically, in an embodiment, the rolling mechanism 20 includes a cam set 21, the roller unit 22, the spreading unit 23, the head unit 24, the glue scraping unit 25, and the needle picking unit 26.

The cam set 21 is connected with the first stepless speed regulation driving mechanism 30, the first stepless speed regulation driving mechanism 30 can drive the cam set 21 to rotate, so that the driving cam on the cam set 21 rotates. The cam set 21 is provided with driving cams corresponding to the roller unit 22, the spreading unit 23, the head unit 24, and the glue scraping unit 25. When the cam set 21 rotates, the roller driving cam in the cam set 21 drives the connecting rod mechanism in the roller unit 22 to operate, so that the four rotating rollers in the roller unit 22 perform opening and closing movements, allowing the inner embryo to be smoothly sent into the space surrounded by the four rotating rollers; the spreading driving cam in the cam set 21 drives the connecting rod mechanism in the spreading unit 23 to operate, performs opening and closing movements, forms a certain tension on the outer wrapping piece, and uniformly spreads the outer wrapping piece, so as to facilitate the outer wrapping piece to be uniformly rolled on the outer surface of the inner embryo; the head driving cam in the cam set 21 drives the connecting rod mechanism in the head unit 24 to operate, performs opening and closing movements, and is used for forming the head of the cigarette, and uniformly presses the outer wrapping piece on the head of the inner embryo; the glue scraping cam in the cam set 21 drives the connecting rod mechanism in the glue scraping unit 25 to operate, performs opening and closing movements, and removes the excess glue on the outer wrapping piece in the suction box. The second stepless speed regulation driving mechanism 40 is used to drive the four rotating rollers in the roller unit 22 to rotate, and uniformly rolls the outer wrapping piece on the inner embryo. The first stepless speed regulation driving mechanism 30 is provided with a needle picking cam 31, the position of the needle picking unit 26 can be adjusted through the needle picking cam 31, and the needle picking unit 26 is used to pick the outer wrapping piece adsorbed on the suction box to the inner embryo, so as to facilitate the roller pressing forming.

[0055] Preferably, in an embodiment, the first stepless speed regulation driving mechanism 30 includes a main shaft 32 and a first servo motor 33. The main shaft 32 is rotatably mounted on the rack 10 and connected with the cam set 21, and is used to drive the cam set 21 to operate. The output shaft of the first servo motor 33 is connected with the main shaft 32, and is used to drive the main shaft 32 to rotate. That is, in an embodiment, the cam set 21 is driven to operate by the servo motor.

[0056] Preferably, in an embodiment, the first stepless speed regulation driving mechanism 30 further includes a shaft coupling 34 and a scale disc 35. The main shaft 32 is connected with the output shaft of the first servo motor 33 through the shaft coupling 34, so that the reliability of transmission can be better guaranteed. The scale disc 35 is arranged on the main shaft 32.

[0057] Specifically, in an embodiment, the coupling 34 connects the first servo motor 33 and the main shaft 32 by a clamp. The first servo motor 33 is connected to a mounting base 36, which is mounted on the main frame of the machine by screws. The dial 35 is mounted on the main shaft 32 by a key. The main shaft 32 is mounted on the frame 10 by a sliding bearing. The cams in all cam sets 21 are fixedly mounted on the main shaft 32 by keys and screws. A flange base 37 is mounted on the frame 10 by screws, and the sliding bearing can be mounted at the flange base 37.

[0058] Preferably, in an embodiment, the second stepless speed regulation driving mechanism 40 comprises a second servo motor 41, a transmission assembly 42, and a synchronous belt 43. The output shaft of the second servo motor 41 is provided with a first synchronous pulley. The transmission assembly 42 is arranged on the frame 10 and connected to the roller pressing unit 22 to drive the roller pressing unit 22 to rotate. The transmission assembly 42 is provided with a second synchronous pulley 421, which is in driving connection with the first synchronous pulley through the synchronous belt 43. Thus, when the second servo motor 41 operates, the transmission assembly 42 can be driven to operate synchronously through the synchronous belt 43.

[0059] It can be understood that the existing coiling device adopts a multi-stage closed gear transmission mode to achieve power transmission, fills with lubricating grease inside, and the rotation speed ratio of each component is constant and cannot be changed. The multi-stage gear backlash causes transmission error amplification, affects the accuracy of transmission, and the gear transmission is contaminated with oil, needs to be lubricated regularly, increases the maintenance strength, and is not conducive to environmental protection requirements.

[0060] In an embodiment, the coiling device 100 adopts belt transmission instead of gears to achieve oil-free and high transmission accuracy and reliability, so that the coiling device 100 does not need to be lubricated regularly and reduces pollution. Compared with the existing coiling device, the coiling device 100 simplifies the mechanical structure, expands the applicable specifications, and is more convenient to operate, debug, and maintain, thereby improving the work efficiency.

[0061] The main function of the transmission assembly 42 is to realize the power transmission of the two groups of rotating rollers in the roller pressing unit 22. Preferably, in an embodiment, the transmission assembly 42 comprises a connecting flange 422, a transmission shaft 423, a gear 424, and the second synchronous pulley 421.

The gear 424 is arranged on the transmission shaft 423 and connected with the roller pressing unit 22. The second synchronous pulley 421 is arranged on the transmission shaft 423. When the second servo motor 41 operates, the second synchronous pulley 421 is driven to rotate by the synchronous belt 43, the second synchronous pulley 421 drives the transmission shaft 423 to rotate, so that the transmission shaft 423 drives the gear 424 to drive the roller pressing unit 22 through the gear 424.

[0062] Preferably, in an embodiment, the gear 424 is arranged on the transmission shaft 423 through a one-way bearing 425. That is to say, the transmission assembly 42 in the coiling device 100 adopts one-way rotation. The one-way bearing 425 is adopted to realize one-way rotation, reverse locking, and avoid reverse rotation caused by the opening and closing of the roller pressing unit 22 during the coiling process, so that the coiling process is stable and reliable.

[0063] Preferably, in an embodiment, the transmission shaft 423 is installed on the connecting flange 422 through a bearing 426. Thus, the wear between components can be better avoided, and the service life is improved.

[0067] Preferably, in an embodiment, the linear driving assembly 51 comprises a third servo motor 511 and an electric cylinder unit 512. The output shaft of the third servo motor 511 is connected with the movement shaft of the electric cylinder unit 512. The top head 52 is arranged at the top of the electric cylinder unit 512 and can move under the driving of the electric cylinder unit 512. That is, in an embodiment, the top head 52 is driven by a servo cylinder.

[0068] Preferably, in an embodiment, the top head 52 is arranged at the top of the electric cylinder unit 512 and is locked by a locking nut 53, so that the locking effect of the top head 52 can be better guaranteed. The electric cylinder unit 512 is fixed with the frame 10 by a clamp 54 and a second mounting seat 55, so that the reliability of the connection can be better guaranteed.
