Description

Technical Field

[0001] The invention relates to the technical field of tobacco auxiliary tools, and in particular to a filter rod filling device and a filter rod filling method. Background Art

[0002] The structure of traditional cigarette filter rods is fixed and single. In recent years, with the continuous optimization and adjustment of cigarette structures, in order to improve the smoking quality of cigarettes and meet the sensory needs of consumers, some cigarette manufacturers have begun to use functional filter rods, which give cigarettes an aroma effect, such as popping bead filter rods and scented wire filter rods. On the other hand, the smoke concentration is adjusted through the perforated structure to achieve a soft smoke effect, thereby providing consumers with a different sensory enjoyment. However, most cigarettes on the market are currently single-flavored, that is, a box of cigarettes can only give consumers one feeling. Some products have achieved the adjustment of smoke concentration, but cannot change the aroma.

[0003] In order to meet the personalized requirements of consumers, the applicant has come up with a solution, that is, to separate the cigarette from the filter rod, and to set a cavity at the end of the cigarette, so that smokers can select filter rods with different functional effects and insert them into the cavity according to their needs to obtain different flavors, concentrations, etc. However, due to the small size of the filter rod, it is inconvenient to take and load, and there is even a risk of falling. Therefore, the problem of difficulty in loading the filter rod into the cigarette has brought inconvenience to smokers, and to some extent hindered the implementation of the above technical solution.

When the pushing unit 5 slides to the second position along the second direction, the filter rod 1 in the rod storage unit 4 falls into the first cavity 31 through the inlet 32. When the pushing unit 5 slides to the first position along the first direction, the pushing unit 5 pushes the filter rod 1 out of the outlet 33. The first position is the limit position of the pushing unit 5 sliding along the first direction, and the second position is the limit position of the pushing unit 5 sliding along the second direction.

[0091] By adopting the above technical solution, by storing the filter rod 1 into the rod storage unit 4 and pushing the filter rod 1 into the cavity 21 at the end of the cigarette 2 through the pushing unit 5, consumers can conveniently load filter rods 1 with different functions into the cigarette 2 according to their own needs, thereby meeting personalized needs such as multiple flavors, styles, and concentrations for a box of cigarettes.

[0092] When the filter rod 1 needs to be loaded into the cavity 21 of the cigarette 2, first, slide the pushing unit 5 to the second position, so that the filter rod 1 located in the rod storage unit 4 falls into the first cavity 31 through the inlet 32; then, place the end of the cigarette 2 with the cavity 21 at the outlet 33, so that the cavity 21 is connected to the outlet 33; finally, slide the pushing unit 5 to the first position, and the pushing unit 5 pushes the filter rod 1 from the first cavity 31 into the cavity 21 of the cigarette 2. The operation is simple and convenient.

[0093] Furthermore, the first cavity 31 is as follows Figure 5 As shown, including:

[0094] A secondary push rod channel 311 is located below the feed inlet 32, and the secondary push rod channel 311 is connected to the feed inlet 32;

[0095] The main push rod channel 312 is located below the secondary push rod channel 311. The main push rod channel 312 is connected to the discharge port 33. The material discharge channel 313 is connected to the secondary push rod channel 311 at one end and to the main push rod channel 312 at the other end.

[0096] Push unit 5 Figure 6 As shown, including:

[0097] A secondary push rod 51 is disposed in the secondary push rod channel 311;

[0098] A main push rod 52 is disposed in the main push rod channel 312;

[0099] A connecting member 53, which is connected to the main push rod 52 and the secondary push rod 51 respectively;

[0100] The secondary push rod channel 311 includes a first sliding section 314, a first temporary storage section 315 and a blanking section 316 arranged in sequence along the first direction. The secondary push rod 51 is arranged in the first sliding section 314, the first temporary storage section 315 is located below the feed inlet 32, and the blanking section 316 is located above the intersection of the blanking channel 313 and the secondary push rod channel 311;

[0101] The main push rod channel 312 includes a second sliding section 318 and a second temporary storage section 319 sequentially arranged along the first direction, the main push rod 52 is arranged in the second sliding section 318, and the second temporary storage section 319 is located below the intersection of the blanking channel 313 and the main push rod channel 312;

[0102] When the pushing unit 5 slides to the second position along the second direction, Figure 7 As shown, the filter rod 1 in the rod storage unit 4 falls into the first temporary storage section 315 through the feed port 32, and the filter rod 1 in the drop section 316 falls into the second temporary storage section 319 through the drop channel 313. When the push unit 5 slides to the first position along the first direction, as shown in FIG. Figure 8 As shown, the secondary push rod 51 pushes the filter rod 1 located in the first temporary storage section 315 into the discharge section 316 , and the main push rod 52 pushes the filter rod 1 located in the second temporary storage section 319 out of the discharge port 33 .

[0103] Here, taking the initial position of the push unit 5 at the first position as an example, when the filter rod 1 needs to be loaded into the cavity 21 of the cigarette 2, if the filter rod 1 is not loaded into the first cavity 31, the push unit 5 can be first slid to the second position, so that the filter rod 1 in the rod storage unit 4 falls into the first temporary storage section 315 through the feeding port 32, and then the push unit 5 is slid to the first position, and the secondary push rod 51 pushes the filter rod 1 in the first temporary storage section 315 into the dropping section 316. At this time, the main push rod 52 has slid into the second temporary storage section 319, so the filter rod 1 in the first temporary storage section 315 will not fall into the second temporary storage section 319. Subsequently, the pushing unit 5 is slid to the second position, so that the filter rod 1 located in the rod storage unit 4 falls into the first temporary storage section 315 through the feed port 32, and the filter rod 1 located in the blanking section 316 falls into the second temporary storage section 319 through the blanking channel 313; then the end of the cigarette 2 with the cavity 21 is placed at the discharge port 33, so that the cavity 21 is connected to the discharge port 33; finally, the pushing unit 5 is slid to the first position, the secondary push rod 51 pushes the filter rod 1 located in the first temporary storage section 315 into the blanking section 316, and the main push rod 52 pushes the filter rod 1 located in the second temporary storage section 319 from the second temporary storage section 319 into the cavity 21 of the cigarette 2, thereby completing the filter rod filling. After the filter rod filling is completed for the first time, the filter rod 1 has been loaded into the blanking section 316. If the filter rod 1 is subsequently loaded into the cavity 21 of the cigarette 2, the filter rod filling can be completed by sliding the pushing unit 5 to the second position first and then to the first position.

[0104] By adopting the above technical solution, a secondary push rod channel 311 separated from the main push rod channel 312 is set, and the filter rod 1 is pushed into the cigarette 2 twice, so that the filter rod 1 that is not pre-filled can be retained in the secondary push rod channel 311 and isolated from the main push rod channel 312, thereby effectively preventing the filter rod 1 from falling out of the discharge port 33; and, when moisture, dust or stolen goods from the outside enter the main push rod channel 312 from the discharge port 33, the filter rod 1 retained in the secondary push rod channel 311 will not be damp or contaminated, which can protect the filter rod 1.

[0105] Furthermore, it also includes an elastic member 55, which is arranged on the main push rod 52 or the secondary push rod 51. When the push unit 5 moves in the first direction, the elastic member 55 applies a force in the second direction to the push unit 5. Specifically, the elastic member 55 is a spring, which is sleeved on the main push rod 52 or the secondary push rod 51. Here, taking the spring sleeved on the main push rod 52 as an example, a second protrusion 521 is arranged on the outer wall of the main push rod 52, and a first protrusion 35 is arranged on the inner wall of the main push rod channel 312. The two ends of the spring are respectively fitted with the first protrusion 35 and the second protrusion 521, so that when the push unit 5 moves in the first direction, the spring can be compressed. By providing the elastic member 55, the push unit 5 can be automatically reset after completing the movement in the first direction, and there is no need to manually drive the push unit 5 to move in the second direction, which is convenient to use.

[0106] Furthermore, a limiting groove 34 is provided on the side wall of the shell 3, and the connecting member 53 is arranged in the limiting groove 34. The connecting member 53 can slide in the limiting groove 34 as the pushing unit 5 runs. The end of the limiting groove 34 close to the first direction is the first limiting end, and the end of the limiting groove 34 close to the second direction is the second limiting end. When the pushing unit 5 slides to the first position, the connecting member 53 fits with the first limiting end to limit the first position of the pushing unit 5. When the pushing unit 5 slides to the second position, the connecting member 53 fits with the second limiting end to limit the second position of the pushing unit 5.

[0107] By adopting the above technical solution, the first position and the second position of the pushing unit 5 are limited by the contact between the connecting member 53 and the two ends of the limiting groove 34, so that the operating position of the pushing unit 5 can be accurate, thereby preventing the pushing unit 5 from squeezing and deforming the filter rod 1 due to inaccurate operating position.

[0108] Furthermore, a pressing portion 54 is further provided at the end of the connecting member 53, and the pressing portion 54 is located outside the limiting groove 34. The consumer can drive the pushing unit 5 to operate by pushing the pressing portion 54, which is convenient to use.

[0109] Furthermore, a first guide section 317 is provided between the first temporary storage section 315 and the blanking section 316. The cross section of the first guide section 317 is circular, and the cross-sectional area of ​​the first guide section 317 gradually decreases along the first direction. By providing the first guide section 317, the filter rod 1 can be guided during the process of running from the first temporary storage section 315 to the blanking section 316, so that the filter rod 1 runs smoothly.

[0110] Furthermore, the cross-sectional area of ​​the end of the first guide section 317 close to the first direction is smaller than the cross-sectional area of ​​the filter rod 1, so that the filter rod 1 can enter the blanking section 316 only under the squeezing action of the secondary push rod 51, thereby preventing the filter rod 1 from falling into the main push rod channel 312 through the blanking channel 313 due to shaking of the filter rod 1 filling device.

[0111] Furthermore, a second guide section 320 is provided between the second temporary storage section 319 and the discharge port 33. The cross section of the second guide section 320 is circular, and the cross-sectional area of ​​the second guide section 320 gradually decreases along the first direction. By providing the second guide section 320, the filter rod 1 can be guided during the process of running from the second temporary storage section 319 to the discharge port 33, so that the filter rod 1 runs smoothly.

[0112] Furthermore, the cross-sectional area of ​​one end of the second guide section 320 close to the first direction is smaller than the cross-sectional area of ​​the filter rod 1 , which can prevent the filter rod 1 from falling out of the discharge port 33 without being squeezed by the main push rod 52 .

[0113] Furthermore, the filter rod loading device further comprises a base 7, which is fixedly connected to the side of the housing 3 close to the first direction by bolts, and a mounting cavity 71 is provided on the base 7, which is communicated with the discharge port 33. When loading the filter rod 1 into the cigarette 2, the cigarette 2 can be inserted into the mounting cavity 71, thereby playing the role of fixing the cigarette 2 and enabling the filter rod 1 and the cavity 21 of the cigarette 2 to be better docked, so as to prevent the filter rod 1 from being misaligned with the cavity 21, and the filter rod 1 cannot be smoothly loaded into the cavity 21.

[0114] Furthermore, a guide member 72 is fixedly connected to one end of the installation cavity 71 close to the second direction. Fig. 9 As shown, the guide member 72 is arranged inside the installation cavity 71, and a guide hole 721 is arranged inside the guide member 72. The cross-sectional area of ​​the guide hole 721 gradually decreases along the first direction, and the diameter of the end of the guide hole 721 close to the first direction is smaller than the diameter of the filter rod 1. By setting the guide hole 721, the filter rod 1 can be guided during the insertion into the cavity 21, and by setting the diameter of the end of the guide hole 721 close to the first direction to be smaller than the diameter of the filter rod 1, the diameter of the filter rod 1 can be smaller than the diameter of the cavity 21 of the cigarette 2 when the filter rod 1 is just squeezed out of the guide hole 721, thereby facilitating the filter rod 1 to enter the cavity 21 and making the filling process of the filter rod 1 smoother.

[0115] Furthermore, the outer contour of the guide member 72 is truncated cone-shaped, the cross-sectional area of ​​the outer contour of the guide member 72 gradually decreases along the first direction, and the outer edge diameter of the guide member 72 at one end close to the first direction is smaller than the diameter of the cavity 21 .

[0116] By adopting the above technical solution, when the cigarette 2 is inserted into the installation cavity 71, the outer wall of the guide 72 can be smoothly inserted into the cavity 21 of the cigarette 2, thereby supporting and trimming the cavity 21, preventing the cigarette 2 from collapsing or deforming due to squeezing or other reasons, resulting in the filter rod 1 being unable to be inserted into the cavity 21.

[0117] Furthermore, a guiding slope 711 is processed at one end of the installation cavity 71 close to the first direction. The guiding slope 711 is arranged at an acute angle with the first direction so that the cigarette 2 can be smoothly inserted into the installation cavity 71 .

[0118] Furthermore, the rod storage unit 4 can be detachably connected to the shell 3. Specifically, a mounting groove 36 can be provided on the shell 3 and the rod storage unit 4 can be placed in the mounting groove 36. Alternatively, a sliding groove or a card groove can be provided above the shell 3 to install the rod storage unit 4.

[0119] By adopting the above technical solution, the rod storage unit 4 can be removed from the housing 3, and then the filter rods 1 can be loaded into the rod storage unit 4, which is convenient for manual operation.

[0120] Furthermore, a handle 43 is provided on the rod storage unit 4, so that the rod storage unit 4 can be conveniently taken out and placed.

[0121] Furthermore, the mounting groove 36 includes a working area 361 and a preparation area 362. The working area 361 is used to place a rod storage unit 4, and the preparation area 362 is used to place multiple rod storage units 4. The feed port 32 is arranged below the working area 361. A take-in and take-out port 37 is provided above the working area 361. A groove body 38 is provided above the preparation area 362. The groove body 38 is connected to the take-in and take-out port 37. The handle 43 of the rod storage unit 4 placed in the preparation area 362 extends from the groove body 38 to the outside of the groove body 38.

[0122] By adopting the above technical solution, a variety of storage rod units 4 with different functional filter rods 1 can be placed on the filter rod 1 filling device at the same time. When the storage rod unit 4 needs to be replaced, it is only necessary to take out the storage rod unit 4 in the working area 361 from the loading and unloading port 37, and then put the storage rod unit 4 in the preparation area 362 into the working area 361, so as to facilitate consumers to choose to replace the storage rod unit 4 according to their own needs.

[0123] Furthermore, a slide groove 44 is provided at the bottom of the rod storage unit 4. Fig.10 As shown, the rod storage unit 4 further includes a push-pull plate 45, which is detachably arranged in the slide slot 44. When the rod storage unit 4 is placed alone and not loaded into the housing 3, the push-pull plate 45 is inserted into the slide slot 44, and the push-pull plate 45 can prevent the filter rod 1 from falling out of the opening 42 of the rod storage unit 4.

[0124] Furthermore, a mounting piece is provided on the housing 3 for mounting a smoking auxiliary device. Specifically, the smoking auxiliary device may be a lighter or other smoking auxiliary devices.

[0125] By adopting the above technical solution, multiple functions are integrated into one, which can avoid consumers from carrying too many smoking tools.

[0126] Furthermore, the width of the opening 42 is greater than the diameter of the filter rod 1 and less than 1.5 times the diameter of the filter rod 1, and the length of the opening 42 is greater than the length of the filter rod 1 and less than 1.5 times the length of the filter rod 1. This design allows only one of the multiple filter rods 1 in the rod storage unit 4 to fall into the first cavity 31 at a time without causing the opening 42 to get stuck or the filter rod 1 to fall unsmoothly.
