[0044] In the present disclosure, when a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other device without an intermediate device, or may not be directly connected to the other device but have an intermediate device.

[0045] All terms (including technical terms or scientific terms) used in the present disclosure have the same meanings as those understood by ordinary technicians in the field to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0046] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0047] Figure 1 is a schematic diagram of the structure of some embodiments of the cigarette paper clamping device according to the related art, referring to Figure 1In the related art, the manipulator of the automatic cigarette paper feeding device automatically grabs the cigarette paper and sends it to the front end of the cigarette paper clamping device. The manipulator pushes the cigarette paper toward the cigarette paper clamping device, so that the paper core ejection plate 71 compresses the three ejection pin compression springs 72 to store energy. At the same time, the paper core ejection plate 71 pushes the oblique pin 73 to overcome the action of the oblique pin compression spring 74 and move toward the rotating plate 75. Under the action of the inclined surface of the oblique pin 73 and the square groove of the rotating plate 75, the rotating plate 75 overcomes the pulling force of the rotating plate tension spring 76 and rotates. The rotating plate 75 is limited and fixed by the rotating plate positioning screw 77. At this time, the telescopic claw clamps the cigarette paper core.

[0048] When the cigarette paper is used up, the remaining cigarette paper core needs to be ejected to facilitate the next cigarette paper loading. At this time, the telescopic claw is loosened, and the ejection cylinder 78 extends to push the bevel pin 73, overcoming the effect of the bevel pin compression spring 74, so that the rotating disk 75 rotates to disengage the limiting fixation of the rotating disk positioning screw 77, releasing the three ejection pin compression springs 72 to push the pin 79 and the paper core ejection disk 71 to eject the cigarette paper core.

[0049] In addition, since different brands of cigarettes correspond to different specifications of cigarette paper width, when changing cigarette brands or maintaining and repairing the cigarette paper clamping device, it is necessary to calibrate the position of the cigarette paper clamping device and the specified reference surface of the equipment factory design to determine the center plane position of the cigarette paper during operation, so that it meets the quality requirements of the cigarette rolling and forming process.

[0050] The fixation and release of the three pop-up pin compression springs 72 after compression and energy storage are achieved by changing the relative position of the inclined surface area of ​​the bevel pin 73 and the square groove on the rotating disk 75 by the pop-up cylinder 78. The entire rotating disk 75 contains a series of parts such as a rotating disk tension spring 76, a rotating disk positioning screw 77, and a pop-up pin compression spring 72. There are many parts, the assembly is complicated, and there are many working procedures to be executed. When a link or part fails after long-term operation, the three pop-up pin compression springs 72 will not be able to be fixed after compression and energy storage, or cannot be released when needed, which seriously damages the stability of the cigarette paper conveying process.

[0051] The cigarette paper core is removed by pushing the pin 79 and the paper core ejection plate 71 through three ejection pin compression springs 72 to eject the cigarette paper core. The core ejection plate 71 sags due to gravity, which increases the friction with the clamping ring. In severe cases, the cigarette paper core cannot be ejected, making it impossible to load new cigarette paper.

[0052] Under the action of the locking pin sleeve 82, the locking tapered top screw 81 causes the locking pin 83 with the tapered groove to move laterally. After long-term operation, the matching surfaces between the tapered top screw 81 and the locking pin 83 with the tapered groove are easily worn, resulting in the failure of the clamping function of the cigarette paper clamping device and causing the cigarette paper to deviate from the working position.

[0053] When calibrating the cigarette paper clamping device, it is necessary to determine the center plane position of the cigarette paper by adjusting the distance between the three special-shaped calibration fixtures and the specified reference plane designed by the equipment at the factory. The adjustment requirements for each fixture distance are high, and the three fixture positions are prone to relative errors during the operation process, resulting in insufficient accuracy of the relative position of the calibrated cigarette paper. In addition, the cigarette paper clamping device needs to be calibrated every time the cigarette brand is changed or maintenance is performed, which reduces work efficiency.

[0054] The reliability of the paper core ejecting operation of the cigarette paper clamping device in the related art is poor, which affects the loading of new cigarette paper; the clamping ring is easy to loosen, causing the cigarette paper to deviate, affecting the supply of cigarette paper; the calibration operation is cumbersome and inefficient.

[0055] In view of this, in one aspect of an embodiment of the present disclosure, a cigarette paper clamping device is provided to help improve the reliability of cigarette paper supply.

[0056] Figure 2 is a schematic diagram of the structure of some embodiments of the cigarette paper clamping device disclosed in the present invention, with reference to Figure 2 The cigarette paper clamping device comprises a clamping assembly 1, a clamping ring 2, an ejection ring 3 and an ejection assembly. The clamping assembly 1 comprises a main body 11 and a telescopic claw 12 that can be telescopic relative to the main body 11, and the number of the telescopic claw 12 can be three. The main body 11 includes but is not limited to being cylindrical, and the telescopic claw 12 is arranged along the circumference of the main body 11 and is telescopic along the axial direction of the main body 11.

[0057] The clamping ring 2 is sleeved on the outer periphery of the clamping assembly 1 and has a first hole 21 opened along the axial direction of the clamping ring 2. The inner periphery of the clamping ring 2 is provided with a groove that cooperates with the telescopic claw 12 to prevent interference with the telescopic claw 12 when the telescopic claw 12 is extended.

[0058] The ejection ring 3 is sleeved on the outer circumference of the clamping assembly 1 and has a second hole 31 opened along the axial direction of the ejection ring 3 and corresponding to the first hole 21 . The end surface of the ejection ring 3 away from the clamping ring 2 is used to abut against the cigarette paper 6 .

[0059] The ejection ring 3 and the clamping ring 2 are sequentially arranged along the axis on the outer periphery of the clamping assembly 1, and the outer end surface of the ejection ring 3 is used to contact the cigarette paper 6. The inner diameter of the paper core 61 of the cigarette paper 6 is equal to the inner diameter of the ejection ring 3, and the outer diameter of the paper core 61 is smaller than the outer diameter of the ejection ring 3. The inner periphery of the ejection ring 3 is also provided with a groove that cooperates with the telescopic claw 12.

[0060] The pop-up assembly is provided through the first hole 21 and the second hole 31, and can be compressed along the axial direction of the clamping ring 2. The pop-up assembly can be squeezed and compressed to store energy, so that when the telescopic claw 12 releases the paper core 61, the paper core 61 is ejected by the stored energy. The number of the first hole 21 and the second hole 31 can be three, including but not limited to being distributed at equal angles along the circumference of the clamping ring 2 and the pop-up ring 3, respectively.

[0061] The clamping assembly 1 has a first working state and a second working state. The clamping assembly 1 is configured to extend the telescopic claw 12 relative to the main body 11 to cross the ejection ring 3 to hold the paper core 61 of the cigarette paper 6 in the first working state, so that the ejection assembly maintains a compressed energy storage state. The clamping assembly 1 is configured to retract the telescopic claw 12 in the second working state to release the ejection assembly, so that the ejection ring 3 moves away from the clamping assembly 1 and drives the paper core 61 to separate from the ejection ring 3.

[0062] The cigarette paper 6 is wound around the outer circumference of the paper core 61. The clamping assembly 1 is in the first working state. The cigarette paper clamping device is used to supply the cigarette paper 6. The end picker sends the cigarette paper 6 to the cigarette paper clamping device, pushes the pop-up ring 3 to move in the direction close to the clamping ring 2, and squeezes the pop-up assembly. The telescopic claw 12 extends to the outer end of the pop-up ring 3 relative to the main body 11. The telescopic claw 12 contacts the inner wall of the paper core 61 to clamp the paper core 61, and limits the axial displacement of the pop-up ring 3 and the clamping ring 2, so that the pop-up ring 3 remains in the state of squeezing the pop-up assembly. At this time, the cigarette paper 6 can be supplied to the rolling device. In the cigarette paper 6 supply state, the pop-up assembly is always in a compressed energy storage state.

[0063] When a roll of cigarette paper 6 is used up, the clamping assembly 1 switches to the second working state, the telescopic claw 12 releases the inner wall of the paper core 61, and retracts relative to the pop-up ring 3 and the clamping ring 2. At this time, the pop-up assembly releases and pushes the pop-up ring 3 to move away from the clamping ring 2, thereby driving the paper core 61 to pop out and separate from the pop-up ring 3 so that new cigarette paper 6 can be replaced.

[0064] In the present embodiment, the ejection ring 3 and the clamping ring 2 cooperate with the ejection assembly to store energy when the cigarette paper 6 is supplied, and release the stored energy to eject the paper core 61 when the cigarette paper 6 is used up. Compared with the complex structure and mechanical coordination method of the clamping device in the related art, the cigarette clamping device of the present embodiment realizes energy storage and ejection operations through a simple and reliable connection relationship, simplifies the energy storage structure, effectively reduces the risk of component damage or failure of the coordination relationship affecting the supply of cigarette paper 6, and reduces the energy loss of the accumulated capacity of the ejection assembly in the complex mechanical conduction process, so that the energy storage and release operations of the cigarette paper clamping device are more stable and reliable, and the cigarette paper 6 can be continuously, stably and well-delivered to the rolling and forming system of the rolling machine, which helps to improve the supply efficiency of the cigarette paper 6 and achieve higher cigarette quality.

[0065] refer to Figure 2 In some embodiments, the ejection assembly includes an ejection pin 41 , a first fastener 42 , and an elastic member 43 .

[0066] The pop-up pin 41 is inserted into the first hole 21, and the pop-up pin 41 is inserted into the clamping ring 2 from the end close to the clamping assembly 1. The first fastener 42 is inserted into the second hole 31 and connected to the pop-up pin 41. The end of the pop-up pin 41 close to the pop-up ring 3 is provided with a threaded hole. The first fastener 42 includes but is not limited to a fastening screw, which can be threadedly connected with the threaded hole at the end of the pop-up pin 41.

[0067] The elastic member 43 is passed through the first hole 21 , abuts against the side of the pop-up ring 3 close to the clamping ring 2 , and is sleeved on the outer periphery of the pop-up pin 41 . The elastic member includes but is not limited to a compression spring.

[0068] The clamping assembly 1 is configured to enable the ejection ring 3 to press the elastic member 43 toward the clamping ring 2 in the first working state, and the clamping assembly 1 is configured to loosen the paper core 61 to release the elastic member 43 in the second working state.

[0069] In this embodiment, the pop-up assembly includes a first fastener 42 and an ejection pin 41 that are interconnected, and an elastic member 43 that is sleeved outside the first fastener 42, so that the pop-up ring 3 compresses the elastic member 43 as the end picker is squeezed and the telescopic claw 12 is held, and the paper core 61 is ejected as the elastic member 43 is released. Compared with the related technology in the complex mechanical assembly structure, the utilization rate of the accumulated elastic potential energy can be improved, and it can be converted into mechanical energy for the paper core 61 to the greatest extent, thereby improving the reliability of the ejection.

[0070] refer to Figure 2 In some embodiments, the ejection assembly further includes a sleeve 44, which is inserted into the first hole 21 and sleeved on the outer periphery of the elastic member 43. The sleeve 44 includes but is not limited to a metal sleeve, such as a copper sleeve. The sleeve 44 is movable in the first hole 21, and can reduce the friction between the ejection pin 41 and the elastic member 43, thereby reducing the energy loss of the elastic member 43.

[0071] In this embodiment, a sleeve 44 is provided outside the elastic member 43, and the sleeve 44 at least partially covers the outer circumference of the elastic member 43. Based on a certain sliding space of the elastic member 43, it is possible to prevent the elastic member 43 from getting stuck in the first hole 21 during the compression or release process, so that the cigarette paper clamping device has higher operability and reliability.

[0072] refer to Figure 2 In some embodiments, the first hole 21 has a first hole section close to the clamping assembly 1 and a second hole section away from the clamping assembly 1 along the axial direction of the clamping ring 2, the diameter of the second hole section is larger than the first hole section, and the second hole section is interference fit with the outer periphery of the sleeve 44. The diameter of the first hole section is adapted to the shape of the large head end of the ejection pin 41.

[0073] In this embodiment, the second hole section with a larger aperture is arranged on the side close to the pop-up ring 3 and is interference fit with the sleeve 44. The pop-up pin 41 is inserted into the first hole 21 from the first hole section with a smaller aperture. The first hole 21 is set as a stepped hole, which can make the first hole 21 fit more closely with the sleeve 44 and the pop-up pin 41 respectively, reduce the shaking during the movement, and improve the operability and operation stability of the cigarette paper clamping device.

[0074] refer to Figure 2 In some embodiments, the cigarette paper clamping device further comprises one or more calibration rings 5 ​​, which are sleeved on the outer circumference of the clamping assembly 1 and located on a side of the clamping ring 2 away from the ejection ring 3 .

[0075] The calibration ring 5 has a third hole 51 corresponding to the first hole 21 and the second hole 31, and the ejection pin 41 passes through the calibration ring 5 and the clamping ring 2 and is connected to the first fastener 42. The number of calibration rings 5 ​​can be adjusted according to different specifications of cigarette paper 6, so as to adjust the distance between the clamping ring 2 and the center plane of the cigarette paper 6 to the preset position corresponding to the supply of cigarette paper of different specifications, so as to adapt to the production of cigarette paper of different specifications. The calibration ring 5 is close to the designated reference surface designed by the factory of the equipment and is locked with the clamping assembly 1 by screws.

[0076] In this embodiment, the calibration ring 5 can be provided to simplify the installation and calibration operations. The cigarette paper clamping device can be adjusted to the corresponding tooling distance according to cigarette papers 6 of different specifications only by adjusting the number of calibration rings 5. This has good adaptability and can greatly shorten the calibration time, thereby solving the problem of insufficient calibration accuracy in related technologies and achieving better cigarette paper supply accuracy.

[0077] refer to Figure 2 In some embodiments, the second hole 31 is a countersunk hole, and the end of the first fastener 42 away from the clamping ring 2 is flush with the end surface of the pop-up ring 3 away from the clamping ring 2 along the axial direction of the pop-up ring 3.

[0078] In this embodiment, by setting the second hole 31 as a countersunk hole, the outer end of the first fastener 42 is flush with the outer end surface of the pop-up ring 3, preventing the first fastener 42 from affecting the placement of the cigarette paper 6, making the placement of the cigarette paper 6 more precise, and helping to improve the quality and efficiency of the supply of cigarette paper 6.

[0079] refer to Figure 2In some embodiments, the clamping ring 2 further has a through hole 22, the opening direction of the through hole 22 is perpendicular to the radial and axial directions of the clamping ring 2, and a thread can be at least partially provided in the through hole 22. The cigarette paper clamping device further includes a second fastener 23, which is threadedly connected to the through hole 22 to clamp the clamping ring 2 to the outer periphery of the clamping assembly 1. In this embodiment, by providing the through hole 22 and the second fastener 23, the clamping ring 2 and the clamping assembly 1 are reliably clamped, reducing the risk of the clamping ring 2 and the clamping assembly 1 being loosened, resulting in the axial displacement of the clamping ring 2 and affecting the supply accuracy of the cigarette paper 6.

[0080] refer to Figure 2 In some embodiments, the thickness of the ejection ring 3 along the axial direction is less than or equal to the thickness of the clamping ring 2. In this embodiment, the ejection ring 3 is set to be thinner, which can reduce the risk that the ejection ring 3 cannot eject the paper core 61 due to friction clamping with the clamping ring 2 due to gravity sag, so that the cigarette paper clamping device can assist in realizing more reliable and efficient cigarette paper 6 supply.

[0081] Figure 3 is a schematic diagram of some embodiments of the cigarette paper supply device according to the present disclosure, with reference to Figure 2-3 In another aspect of the embodiments of the present disclosure, a cigarette paper supply device is provided, comprising a cigarette paper clamping device and an end picker as described in any of the above embodiments, the end picker being used to push the cigarette paper 6 toward the cigarette paper clamping device so that the clamping assembly 1 holds the paper core 61 of the cigarette paper 6.

[0082] In this embodiment, the cigarette paper clamping device has a simpler and more reliable structure with a low failure rate. The cigarette paper 6 can be continuously, stably and well-delivered to the rolling and forming system of the rolling machine, which helps to achieve accurate and efficient supply of the cigarette paper 6.

[0083] In another aspect of the embodiments of the present disclosure, a rolling and splicing system is provided, comprising: the cigarette paper supplying device as described above.

[0084] In this embodiment, by adopting the rolling system of the cigarette paper clamping device, the cigarette paper 6 can be continuously, stably and well-quality transported and supplied, making the cigarette rolling operation smoother and more efficient, with a low failure rate and reliable operation, and can improve the quality and efficiency of the rolling.
