Abstract
Description
Technical Field
[0001] The invention relates to the technical field of cigarette laser drilling, and in particular to a cigarette laser drilling method, device and cigarette making machine. Background Art
[0002] In the manufacturing process of cigarettes, in order to reduce the tar content of cigarettes, laser drilling on cigarettes is currently widely used. For example, CN201243618Y discloses a cigarette rotating device of an online cigarette laser drilling machine, which uses a cigarette rotating wheel to drive the cigarette to rotate around its own axis, just like a cigarette rubbing wheel rubbing the cigarette, and then uses a laser to punch holes in the cigarette.
[0003] However, during the laser punching process, tobacco shreds often protrude or become hollow on the cigarettes, resulting in quality defects. Summary of the invention
[0004] The purpose of the present invention is to solve the problem that tobacco shreds are easily protruding or empty in the process of laser drilling of cigarettes, resulting in quality defects in cigarettes. The present invention provides a method, device and cigarette making machine for laser drilling of cigarettes, which can avoid tobacco shreds protruding or empty in the process of laser drilling of cigarettes, thereby improving the quality of cigarettes.
[0005] In order to solve the above technical problems, the inventors explored and found that the reason why tobacco shreds often protrude or become hollow during the laser punching process of cigarettes is that the cigarettes are squeezed to a certain extent when being rubbed by the cigarette wheel, causing the tobacco to fall from the end of the cigarette, resulting in tobacco shreds protruding or becoming hollow.
[0006] To this end, an embodiment of the present invention discloses a cigarette laser punching method, comprising:
[0007] The cigarette is placed between the laser perforated drum and the cigarette pulling roller, wherein the first end surface of the cigarette pulling roller is located between the cigarette lighting end of the cigarette and the second end surface of the cigarette pulling roller, and a certain distance is spaced between the first end surface and the cigarette lighting end;
[0008] The cigarette roller is rotated so that the roller drives the cigarette to rotate around the axis of the cigarette, the axis of the laser perforated drum, the axis of the cigarette and the axis of the cigarette roller are located in the same plane, and the cigarette roller squeezes the cigarette;
[0009] Use laser to punch holes in cigarettes.
[0010] By adopting the above technical solution, by setting the first end face to be a certain distance away from the cigarette lighting end, it is possible to avoid the cigarette roller from contacting the cigarette lighting end, and to avoid the cigarette roller from squeezing the cigarette lighting end, thereby preventing the tobacco from falling from the cigarette lighting end when the cigarette roller drives the cigarette to rotate, causing the cigarette to have protruding tobacco or hollow ends.
[0011] Optionally, the radial dimension reduction of the cigarette under the squeezing action of the cigarette roller is the compression amount, the distance between the first end surface and the cigarette lighting end is the spacing distance, and the value of the compression amount and the value of the spacing distance satisfy a preset function.
[0012] By adopting the above technical solution, the friction between the cigarette roller and the cigarette can be increased by using the cigarette roller to squeeze the cigarette, thereby ensuring that when the first end face is separated from the cigarette lighting end by a certain distance, that is, when the axial working surface of the circumferential surface of the cigarette roller in contact with the cigarette is reduced, there is still sufficient friction between the cigarette roller and the cigarette to drive the cigarette to rotate, thereby avoiding smoke blockage and uneven perforation caused by slipping of the cigarette, thereby ensuring the stability of the cigarette operation.
[0013] Optionally, the preset function is:
[0014] Z=0.02×L+0.1
[0015] Among them, Z is the compression amount and L is the spacing distance.
[0016] By adopting the above technical scheme, the value of the compression amount and the value of the spacing distance satisfy the above preset function. When the spacing distance increases, the compression amount also increases accordingly, so that when the contact area between the cigarette roller and the cigarette is reduced, the pressure of the cigarette roller on the cigarette is increased, so that there is sufficient friction between the cigarette roller and the cigarette to drive the cigarette to rotate and prevent the cigarette from slipping; when the spacing distance decreases, the compression amount also decreases accordingly, so that when the contact area between the cigarette roller and the cigarette is increased, the pressure of the cigarette roller on the cigarette is reduced, so as to avoid the cigarette roller applying unnecessary pressure on the cigarette, thereby preventing the cigarette from being damaged due to excessive squeezing; and when the value of the compression amount and the value of the spacing distance satisfy the above preset function, the compression amount and the spacing distance can be in the best matching state, that is, when the value of a certain compression amount and the value of a certain spacing distance satisfy the above preset function, the compression amount can just ensure the stable rotation of the cigarette at the spacing distance.
[0017] Optionally, the spacing distance is 5-15 mm.
[0018] The above technical solution is adopted, and the spacing distance is set to 5-15mm. When the spacing distance is less than 5mm, the pressing area of the cigarette roller on the cigarette is too large, which easily causes the tobacco to fall from the cigarette lighting end; when the spacing distance is greater than 15mm, the contact area between the cigarette roller and the cigarette is too small, resulting in excessive pressure on the cigarette by the cigarette roller, which easily damages the cigarette. When the spacing distance is 5-15mm, it can effectively prevent the tobacco from falling from the cigarette lighting end and ensure the quality of the tobacco, while ensuring that the cigarette roller can drive the cigarette to rotate normally to avoid damage to the cigarette.
[0019] Optionally, the spacing distance is 10 mm.
[0020] By adopting the above technical solution, the spacing distance is set to 10 mm, which is the optimal spacing distance between the first end surface and the cigarette lighting end.
[0021] Optionally, the compression amount is 0.3 mm.
[0022] By adopting the above technical solution, the compression amount is set to 0.3 mm, which is the optimal compression amount when the spacing distance is 10 mm.
[0023] Optionally, the compression amount is 0.2-0.4 mm.
[0024] By adopting the above technical solution, the compression amount is set to 0.2-0.4mm. When the compression amount is less than 0.2mm, the cigarette is likely to slip; when the compression amount is greater than 0.4mm, the cigarette is likely to be damaged. When the compression amount is 0.2-0.4mm, it can effectively prevent the cigarette from slipping and avoid the cigarette from being damaged.
[0025] The embodiment of the present invention further discloses a cigarette laser punching device, comprising:
[0026] Laser perforated drum;
[0027] A cigarette roller, wherein a certain space is provided between the circumferential surface of the cigarette roller and the circumferential surface of the laser perforated drum wheel for accommodating cigarettes, and the cigarette roller is used to drive the cigarettes to rotate, and the first end surface of the cigarette roller is located between the cigarette lighting end of the cigarette and the second end surface of the cigarette roller, and a certain distance is spaced between the first end surface and the cigarette lighting end;
[0028] A laser generating mechanism, used for emitting laser;
[0029] The axis of the laser perforated drum, the axis of the cigarette and the axis of the cigarette pulling roller are located in the same plane. The minimum distance between the circumferential surface of the cigarette pulling roller and the circumferential surface of the laser perforated drum is the minimum wheel gap. The minimum wheel gap is smaller than the diameter of the cigarette so that the cigarette pulling roller squeezes the cigarette.
[0030] By adopting the above technical solution, by setting the first end face to be a certain distance away from the cigarette lighting end, it is possible to avoid the cigarette roller from contacting the cigarette lighting end, and to avoid the cigarette roller from squeezing the cigarette lighting end, thereby preventing the tobacco from falling from the cigarette lighting end when the cigarette roller drives the cigarette to rotate, causing the cigarette to have protruding tobacco or hollow ends.
[0031] Optionally, the radial dimension reduction of the cigarette under the squeezing action of the cigarette roller is the compression amount, the distance between the first end surface and the cigarette lighting end is the spacing distance, and the value of the compression amount and the value of the spacing distance satisfy a preset function.
[0032] Optionally, the preset function is:
[0033] Z=0.02×L+0.1
[0034] Among them, Z is the compression amount and L is the spacing distance.
[0035] Optionally, the distance between the first end surface and the cigarette lighting end is a spacing distance, and the spacing distance is 5-15 mm.
[0036] Optionally, the spacing distance is 10 mm.
[0037] Optionally, the compression amount is 0.3 mm.
[0038] Optionally, the compression amount is 0.2-0.4 mm.

[0046] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
[0047] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.
[0048] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.
[0049] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0050] To this end, an embodiment of the present invention discloses a cigarette laser punching method, comprising:
[0051] The cigarette 4 is placed between the laser perforated drum 3 and the cigarette roller 1, and the first end surface 11 of the cigarette roller 1 is located between the cigarette lighting end 41 of the cigarette 4 and the second end surface 12 of the cigarette roller 1, and there is a certain distance between the first end surface 11 and the cigarette lighting end 41;
[0052] The cigarette roller 1 is rotated so that the cigarette roller 1 drives the cigarette 4 to rotate around the axis of the cigarette 4, the axis of the laser perforated drum 3, the axis of the cigarette 4 and the axis of the cigarette roller 1 are located in the same plane, and the cigarette roller 1 squeezes the cigarette;
[0053] The cigarette 4 is punched with a laser.
[0054] Specifically, the two ends of the cigarette 4 are respectively a lighting end 41 and a filter end 42, wherein the lighting end 41 is an end for lighting the cigarette 4, and the filter end 42 is an end for the smoker to inhale smoke. The present application does not limit the specific position of the second end face 12. In this embodiment, the second end face 12 is located between the first end face 11 and the filter end 42.
[0055] By adopting the above technical solution, by setting the first end face 11 to be a certain distance away from the cigarette lighting end 41, it is possible to avoid the cigarette roller 1 from contacting the cigarette lighting end 41, and to avoid the cigarette roller 1 from squeezing the cigarette lighting end 41, thereby preventing the cigarette roller 1 from driving the cigarette 4 to rotate, and preventing the tobacco from falling from the cigarette lighting end 41, causing the cigarette 4 to have protruding tobacco or hollow ends.
[0056] Furthermore, the radial dimension reduction of the cigarette 4 under the squeezing action of the cigarette roller 1 is the compression amount, and the distance between the first end surface 11 and the cigarette lighting end 41 is the spacing distance (eg Figure 1 As shown in the dimension L in FIG, the value of the compression amount and the value of the spacing distance satisfy the preset function.
[0057] By adopting the above technical solution, the friction between the cigarette roller 1 and the cigarette 4 can be increased by using the cigarette roller 1 to squeeze the cigarette 4, thereby ensuring that when the first end surface 11 is separated from the cigarette lighting end 41 by a certain distance, that is, when the axial working surface of the circumferential surface of the cigarette roller 1 in contact with the cigarette 4 is reduced, there is still sufficient friction between the cigarette roller 1 and the cigarette 4 to drive the cigarette 4 to rotate, thereby avoiding smoke blockage and uneven perforation caused by the slipping of the cigarette 4, thereby ensuring the stability of the operation of the cigarette 4.
[0058] Furthermore, the preset function is:
[0059] Z=0.02×L+0.1
[0060] Among them, Z is the compression amount and L is the spacing distance.
[0061] By adopting the above technical scheme, the value of the compression amount and the value of the spacing distance satisfy the above preset function. When the spacing distance increases, the compression amount also increases accordingly, so that when the contact area between the cigarette roller 1 and the cigarette 4 decreases, the pressure of the cigarette roller 1 on the cigarette 4 is increased, so that there is sufficient friction between the cigarette roller 1 and the cigarette 4 to drive the cigarette 4 to rotate and prevent the cigarette 4 from slipping; when the spacing distance decreases, the compression amount also decreases accordingly, so that when the contact area between the cigarette roller 1 and the cigarette 4 increases, the pressure of the cigarette roller 1 on the cigarette 4 is reduced, so as to avoid the cigarette roller 1 applying unnecessary pressure on the cigarette 4, thereby preventing the cigarette 4 from being damaged due to excessive squeezing; and when the value of the compression amount and the value of the spacing distance satisfy the above preset function, the compression amount and the spacing distance can be in the best matching state, that is, when the value of a certain compression amount and the value of a certain spacing distance satisfy the above preset function, the compression amount can just ensure the stable rotation of the cigarette 4 at the spacing distance.
[0062] Furthermore, the spacing distance is 5-15 mm.
[0063] By adopting the above technical solution, the spacing distance is set to 5-15mm. When the spacing distance is less than 5mm, the pressing area of the cigarette roller 1 on the cigarette 4 is too large, which easily causes the tobacco to fall from the cigarette lighting end 41; when the spacing distance is greater than 15mm, the contact area between the cigarette roller 1 and the cigarette 4 is too small, resulting in excessive pressure of the cigarette roller 1 on the cigarette 4, which easily damages the cigarette 4. When the spacing distance is 5-15mm, it can effectively prevent the tobacco from falling from the cigarette lighting end 41 and ensure the quality of the tobacco, and at the same time ensure that the cigarette roller 1 can drive the cigarette 4 to rotate normally without damaging the cigarette 4.
[0064] Furthermore, the spacing distance is 10 mm.
[0065] By adopting the above technical solution, the spacing distance is set to 10 mm, which is the optimal spacing distance between the first end surface 11 and the cigarette lighting end 41 .
[0066] Furthermore, the compression amount is 0.3 mm.
[0067] By adopting the above technical solution, the compression amount is set to 0.3 mm, which is the optimal compression amount when the spacing distance is 10 mm.
[0068] Furthermore, the compression amount is 0.2-0.4 mm.
[0069] By adopting the above technical solution, the compression amount is set to 0.2-0.4mm. When the compression amount is less than 0.2mm, the cigarette 4 is likely to slip; when the compression amount is greater than 0.4mm, the cigarette 4 is likely to be damaged. When the compression amount is 0.2-0.4mm, the cigarette 4 can be effectively prevented from slipping and damaged.
[0070] The embodiment of the present invention also discloses a cigarette laser punching device, such as Figure 1 , Figure 3 As shown, including:
[0071] Laser punching drum 3;
[0072] The cigarette roller 1 can rotate around its own axis, and there is a certain space between the circumferential surface of the cigarette roller 1 and the circumferential surface of the laser perforated drum wheel 3 for accommodating the cigarette 4. The cigarette roller 1 is used to drive the cigarette 4 to rotate, and the first end surface 11 of the cigarette roller 1 is located between the cigarette lighting end 41 of the cigarette 4 and the second end surface 12 of the cigarette roller 1, and there is a certain distance between the first end surface 11 and the cigarette lighting end 41;
[0073] The laser generating mechanism 5 is arranged above the cigarette 4 and is used for emitting laser;
[0074] The axis of the laser perforated drum wheel 3, the axis of the cigarette 4 and the axis of the cigarette roller 1 are located in the same plane, and the minimum distance between the circumference of the cigarette roller 1 and the circumference of the laser perforated drum wheel 3 is the minimum wheel gap (e.g. Figure 3 The minimum wheel gap is smaller than the diameter of the cigarette 4, so that the cigarette roller 1 squeezes the cigarette 4.
[0075] Specifically, the two ends of the cigarette 4 are respectively a lighting end 41 and a filter end 42, wherein the lighting end 41 is an end for lighting the cigarette 4, and the filter end 42 is an end for the smoker to inhale smoke. The present application does not limit the specific position of the second end face 12. In this embodiment, the second end face 12 is located between the first end face 11 and the filter end 42.
[0076] By adopting the above technical solution, by setting the first end face 11 to be a certain distance away from the cigarette lighting end 41, it is possible to avoid the cigarette roller 1 from contacting the cigarette lighting end 41, and to avoid the cigarette roller 1 from squeezing the cigarette lighting end 41, thereby preventing the cigarette roller 1 from driving the cigarette 4 to rotate, and preventing the tobacco from falling from the cigarette lighting end 41, causing the cigarette 4 to have protruding tobacco or hollow ends.
[0077] Furthermore, the radial size reduction of the cigarette 4 under the squeezing action of the cigarette roller 1 is the compression amount (i.e., the difference between the diameter of the cigarette 4 when not squeezed and the minimum wheel gap), the distance between the first end face 11 and the cigarette lighting end 41 is the spacing distance, and the value of the compression amount and the value of the spacing distance satisfy a preset function.
[0078] Furthermore, the preset function is:
[0079] Z=0.02×L+0.1
[0080] Among them, Z is the compression amount and L is the spacing distance.
[0081] Furthermore, the distance between the first end surface 11 and the cigarette lighting end 41 is a spacing distance, and the spacing distance is 5-15 mm.
[0082] Furthermore, the spacing distance is 10 mm.
[0083] Furthermore, the compression amount is 0.3 mm.
[0084] Furthermore, the difference between the minimum wheel gap and the diameter of the cigarette 4 is the compression amount of the cigarette 4, and the compression amount is 0.2-0.4 mm.
[0085] Furthermore, it also includes a fixing portion 2 , which is used to install the cigarette roller 1 . The fixing portion 2 is arranged on the first end surface 11 , and the fixing portion 2 does not contact the cigarette lighting end 41 .
[0086] By adopting the above technical solution and providing the fixing portion 2 , the cigarette removing roller 1 can be easily installed.
[0087] Further, such as Figure 2 As shown, the fixing part 2 is a cylinder, a mounting hole 21 is provided on the fixing part 2, a positioning hole 22 is provided on the side wall of the mounting hole 21, the axis of the fixing part 2 and the axis of the mounting hole 21 coincide with the axis of the cigarette removing roller 1, the cross-sectional diameter of the fixing part 2 is smaller than the cross-sectional diameter of the cigarette removing roller 1, and the positioning hole 22 is a threaded hole. When the cigarette removing roller 1 needs to be installed on the mounting shaft, it is only necessary to insert the mounting shaft into the mounting hole 21, then screw the stop screw into the positioning hole 22, and tighten the mounting shaft with the screw, thereby fixing the cigarette removing roller 1.
[0088] Furthermore, the circumferential surface of the cigarette roller 1 is processed with a pattern, and the present application does not limit the specific pattern, and the pattern can be a stripe pattern or a diamond pattern. Providing a pattern on the circumferential surface of the cigarette roller 1 can increase the roughness of the circumferential surface of the cigarette roller 1, thereby increasing the friction between the cigarette roller 1 and the cigarette 6 when the cigarette roller 1 drives the cigarette 4 to rotate, preventing the cigarette 4 from slipping during the rotation process, and improving the stability of the rotation of the cigarette 4.
[0089] The embodiment of the present invention further discloses a cigarette making machine, comprising any one of the aforementioned laser perforating devices.
[0090] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
