[0022] The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0023] Example 1

[0024] like Figure 1As shown, the device for quickly and accurately marking the length of full-size cigarettes comprises a base plate 1, a limit device 2, two positioning devices 3 and a marking device 4. The device for quickly and accurately marking the length of full-size cigarettes in this embodiment has the advantages of high marking efficiency and high accuracy.

[0025] The base plate 1 is a rectangular plate structure, and the two longitudinal sides of the base plate 1 are respectively provided with longitudinal frames 11 extending longitudinally, and one transverse side of the base plate 1 is provided with a transverse frame 12 extending transversely, and the two ends of the transverse frame 12 are respectively connected to one end of the two longitudinal frames 11, and the transverse frame 12 is respectively perpendicular to the two longitudinal frames 11. When placing cigarette samples, all cigarette samples are neatly placed on the upper surface of the base plate 1, and the filter tips of all cigarette samples are against the inner side of the transverse frame 12. At this time, the transverse frame 12 plays a role of limiting the cigarette samples, so that the end faces of the filter tips of all cigarette samples are in the same plane.

[0026] The limiting device 2 can be movably arranged on the base plate 1, and the limiting device 2 is used to limit the cigarette sample between the horizontal frame 12 and the limiting device 2, so as to ensure that the cigarette sample is neatly placed. The limiting device 2 includes a bottom plate 21, which is arranged on the upper surface of the base plate 1, and a horizontally extending limiting baffle 22 is arranged on the horizontal side of the bottom plate 21 close to the horizontal frame 12, and the two longitudinal sides of the bottom plate 21 are respectively provided with longitudinally extending side plates 23, and the two ends of the limiting baffle 22 are respectively connected to one end of the two side plates 23. Further, in order to facilitate the movement of the limiting device 2, in this embodiment, a roller 231 is respectively arranged on the outer side of the two side plates 23, and two rollers 231 are respectively arranged on the lower surface of the bottom plate 21, and the upper surface of the base plate 1 and the inner side of the longitudinal frame 11 are respectively provided with guide grooves 13 corresponding to the rollers 231, and the two guide grooves 13 on the upper surface of the base plate 1 are arranged on the side close to the base plate 1 away from the limiting baffle 22, and are perpendicular to the other horizontal side of the base plate 1. When the limiting device 2 is placed on the upper surface of the base plate 1, the roller 231 cooperates with the guide groove 13 to make the base plate 21 move in the longitudinal direction. Figure 3 As shown, further, the roller 231 on the lower surface of the bottom plate 21 is provided with a brake member 97, and a small hole corresponding to the position of the roller 231 is also provided on the bottom plate 21. The middle part of the brake member 97 is hinged to the fixing seat 96 of the roller 231 through a pin shaft, and one end of the brake member 97 extends into the small hole. When one end of the brake member 97 is pressed downward with a finger, the other end of the brake member 97 is closely fitted with the roller 231 to prevent the roller 231 from rotating, thereby preventing the limit device 2 from moving during the line drawing process, affecting the accuracy of the cigarette sample marking. When one end of the brake member 97 is pushed upward with a finger, the other end of the brake member 97 is kept away from the roller 231, and the roller 231 can rotate freely.

[0027] like Figure 2As shown, two positioning devices 3 are respectively arranged on the outside of two longitudinal frames 11, and the positioning device 3 includes a mechanical counter 31 and a hand-cranked screw rod module 32. The hand-cranked screw rod module 32 includes a fixed plate 312, a screw rod 313, a hand crank 314, a guide rail 315 and a slider 316. The fixed plate 312 is connected to the outside of the longitudinal frame 11 by screws, the screw rod 313 is rotatably arranged on the fixed plate 312 through two fixed blocks, the guide rail 315 is arranged between the two fixed blocks, the slider 316 is slidably sleeved on the guide rail 315 and connected with the nut sleeved on the screw rod 313, and the hand crank 314 is connected to one end of the screw rod 313. The driving gear 321 is fixedly sleeved on one end of the screw rod 313, the mechanical counter 31 is arranged on the fixed plate 312, and the driven gear 311 is sleeved on the rotating shaft of the mechanical counter 31, and the driving gear 321 is meshed with the driven gear 311. When the hand crank 314 is driven to rotate, the hand crank 314 can drive the screw rod 313 to rotate coaxially, and then drive the slider 316 to slide along the length direction of the guide rail 315. At the same time, the screw rod 313 drives the rotating shaft of the mechanical counter 31 to rotate through the driving gear 321 and the driven gear 311, and the mechanical counter 31 starts counting. The mechanical counter 31 has four encoding wheels, among which the encoding wheel for the single digit can display a minimum displacement of 0.1 mm. Through the cooperation between the mechanical counter 31 and the hand crank screw rod module 32, the displacement of the ink fountain 41 and the connecting rod 42 can be accurately controlled, thereby effectively improving the accuracy of cigarette sample marking.

[0028] The marking device 4 includes an ink fountain 41 and a connecting rod 42 . The ink fountain 41 is arranged on a slider 316 of the hand-cranked screw module 32 on the right side of the base plate 1 , and the connecting rod 42 is arranged on a slider 316 of the hand-cranked screw module 32 on the left side of the base plate 1 .

[0029] When in use, cigarette samples of the same specification are neatly placed on the upper surface of the base plate 1, and the bottom plate 21 is pushed to move toward the horizontal frame 12, so that the filter tips of all cigarette samples are against the inner side of the horizontal frame 12, ensuring that the end faces of the filter tips of all cigarette samples are in the same plane, and by pressing the control rod 232, the brake pads of the brake device are pressed against the roller 231, and the bottom plate 21 stops moving. Since the specifications of the cigarette samples are the same, the average cigarette butt length of the cigarette samples is known, so by rotating the hand cranks 314 of the two hand crank screw modules 32 respectively, the ink fountain 41 and the connecting rod 42 can be pushed to the preset position (the average cigarette butt length of the cigarette sample), and at this time, the two mechanical counters 31 display the same number, that is, the displacement of the ink fountain 41 and the connecting rod 42 is the same. Then pull the pull line 411 of the ink fountain 41 to the right side of the base plate 1 and connect it to the connecting rod 42. Pull the pull line 411 upward perpendicular to the base plate 1. Release the pull line 411 after reaching a certain height. The pull line 411 rebounds and moves downward, leaving a marking line on each cigarette sample. The marking line is the average cigarette butt length marking line of the cigarette sample of this specification. Due to the provision of a movable bottom plate 21, the full-size cigarette length fast and accurate marking device of this embodiment can be applied to the marking of the cigarette butt length of conventional cigarettes, medium cigarettes, thin cigarettes, and short cigarettes of various specifications with a total length of 70-105mm and unlimited circumferential size. The range of cigarette butt length marking is wide (23.0-45.0mm) and can be accurate to 0.1mm. Since multiple cigarettes can be marked at the same time each time, the full-size cigarette length fast and accurate marking device of this embodiment can effectively improve the marking efficiency of cigarette samples.

[0030] Example 2

[0031] This embodiment is based on the embodiment 1. The difference between this embodiment and the embodiment 1 is that the ink fountain 41 in this embodiment is an automatic retractable ink fountain, which is equipped with a coil spring. The coil spring is connected to the winding wheel of the ink fountain 41. When the pull wire 411 is pulled out, the winding wheel rotates forward and the coil spring is compressed. After the marking is completed, the winding line can rotate in the opposite direction under the action of the coil spring, and the pull wire 411 is wound around the winding wheel, thereby realizing the automatic retraction of the pull wire 411. In this embodiment, the upper surface of the substrate 1 is provided with a first avoidance groove 14 extending laterally. The distance between the first avoidance groove 14 and the horizontal frame 12 is 50 mm, and the width is 10 mm, but it is not limited thereto. A ribbon is provided in the first avoidance groove 14, one end of the ribbon is fixed to one end of the first avoidance groove 14, and the other end of the ribbon is placed on the upper part of the vertical frame 11. When it is necessary to take out the cigarette sample, only the other end of the ribbon needs to be pulled, and the ribbon can take out all the cigarette samples, greatly shortening the time of taking out the cigarette sample. In addition, a second avoidance groove 15 is provided on the upper part of the two longitudinal frames 11 , and the second avoidance groove 15 can reduce the height of the pull line 411 when drawing a line, ensuring that the cigarette samples close to the two longitudinal frames 11 can also leave a marking line.

[0032] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made on the basis of the present invention. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
