TECHNICAL FIELD

[0001] The utility model relates to cigarette manufacturing technical field especially relates to a system is rubbed to thin cigarette. BACKGROUND

[0002] The function of the rubbing drum and rubbing plate is to wrap the assembled cigarettes with the tipping paper sheet, thereby forming double length filter cigarettes. When the rubbing drum receives the assembled cigarettes with the tipping paper sheet from the closing drum, the suction of the air holes on the outer surface of the rubbing drum makes the assembled cigarettes fall into the cigarette groove, and the suction of the air holes on the outer surface of the rubbing drum makes the tipping paper sheet flat on the outer surface with straight lines. When entering the rubbing working position, the assembled cigarettes are taken out of the cigarette groove by the starting rail, and the assembled cigarettes roll between the arc surface of the rubbing drum and the rubbing plate, so that the tipping paper sheet tightly wraps and adheres to the assembled cigarettes to form double length filter cigarettes.

[0003] At present, the ZJ17 thin cigarette production equipment is all transformed from conventional cigarette equipment, but the rubbing plate is not improved in the transformation process, which will cause a series of quality problems when directly used for thin cigarette rubbing. For example, compared with conventional cigarettes, thin cigarettes have smaller diameter, and the arc length of the rubbing plate is too long, which can cause a series of quality problems such as loose and empty head during the rubbing process of the cigarettes. Specifically, the diameter of conventional cigarette is 7.8mm, according to the arc length of the current rubbing plate, the number of rolling of the conventional cigarette on the rubbing plate during the rubbing process is 3 turns, and the diameter of the thin cigarette is about 5.45mm, the number of rolling on the rubbing plate during the rubbing process is about 4.3 turns, and the density of the joint part is reduced due to the excessive number of rubbing turns, thereby forming the problems of loose and empty head.

[0004] The patent file with the announcement number CN220966401U discloses a shortened rubbing plate suitable for thin cigarette and a cigarette rubbing system, which comprises: a rubbing plate body; a rubbing surface, which is shaped on the assembled cigarette supporting wall, and the width of the rubbing surface is greater than that of a cigarette tipping paper; the central angle of the rubbing surface relative to the rotation axis of the rubbing drum is θ, the central angle of the outer surface of the rubbing drum between two adjacent cigarette grooves relative to the rotation axis of the rubbing drum is α, and θ is less than α. The prior art shortens the effective working length of the rubbing plate, avoids the falling of the assembled cigarettes into the cigarette groove of the rubbing drum during the wrapping process of the assembled cigarettes by the cigarette tipping paper, but causes the problem of unstable joint part due to the insufficient number of rubbing turns of the thin cigarette.

DETAILED DESCRIPTION

[0024] The following is a specific embodiment of the present application, which is further described in conjunction with the drawings. The present application is not limited to these embodiments.

[0025] A fine cigarette rolling system, such as Figure 1As shown, the cigarette rolling device comprises a rolling plate 1 and a rolling wheel 2, the rolling wheel 2 comprises a wheel body 22 sleeved with a gas distribution seat 21, the gas distribution seat 21 comprises a negative pressure air inlet 211, a negative pressure air outlet 212 and a rolling interface 213 between the negative pressure air inlet 211 and the negative pressure air outlet 212, and the wheel body 22 is provided with a tobacco groove which can communicate with the negative pressure air inlet 211 and the negative pressure air outlet 212. The rolling plate 1 comprises a working part 11 corresponding to the rolling interface 213 and a mounting part for mounting the rolling plate, and a rolling channel is formed between the rolling interface 213 and the working part 11.

[0026] In use, the wheel body 22 rotates clockwise around the gas distribution seat 21, and a tobacco groove is adsorbed when it rotates to the negative pressure air inlet 211; the wheel body 22 continues to rotate, so that the tobacco groove rotates to the rolling interface 213, and the tobacco groove is no longer communicated with any negative pressure air inlet, so that the tobacco cannot be adsorbed and falls on the working part 11 of the rolling plate 1; the wheel body 22 continues to rotate, and the part without the tobacco groove drives the tobacco to roll on the working part 11, and the tobacco which is rolled and rubbed is rolled to the lower end of the rolling plate 1 and is taken away by the tobacco groove communicated with the negative pressure air outlet 212.

[0027] In some embodiments, in order to improve the rolling fluency, the rolling interface 213 is provided with a groove 2131 to reduce the friction between the wheel body 22 and the rolling interface 213 and improve the rolling fluency of the wheel body 22. Figure 2

[0028] In some embodiments, the rolling plate 1 comprises the working part 11 located upstream and a leading part 12 located downstream of the working part 11 in the rotation direction of the wheel body 22, and the slim cigarette is taken away by the tobacco groove communicated with the negative pressure air outlet 212 in the leading part 12. Figure 3 As shown, the leading part 12 is provided with a plurality of tobacco mist leading grooves 121 in the axial direction of the wheel body 22, which can timely discharge the tobacco mist on the rolling plate 1, avoid the accumulated tobacco mist affecting the rolling quality and being adsorbed by the negative pressure air outlet 212 to cause the blocking problem.

[0029] In the rolling of the slim cigarette, the diameter of the slim cigarette is about 5.45 mm, and the rolling plate 1 will make the rolling number of the tobacco on the working part 11 be about 4.3 turns, and the excessive rolling number will cause the density of the joint part to be reduced, thereby causing the problems of loose joint and empty head. In the present application, the arc length of the working part 11 of the rolling plate 1 in the circumferential direction of the wheel body 22 is controlled to be 51-51.5 mm, preferably 51.3 mm, the arc length of the working part 11 is reduced, the rolling number of the slim cigarette is 3 turns, the joint is firm, the problems of empty head and loose joint are reduced, and the rolling quality of the tobacco is effectively improved.

[0030] ​On the basis of reducing the arc length of the working part 11 of the roller 1, the negative pressure air inlet 211 is further enlarged downward by a certain angle, that is, the end of the negative pressure air inlet 211 close to the negative pressure air outlet 212 is provided with an additional negative pressure air inlet 214, the additional negative pressure air inlet 214 is communicated with the negative pressure air inlet 211, and the increased negative pressure air inlet is used to avoid the cigarette dropping phenomenon caused by the reduction of the arc of the roller 1 before the cigarette enters the roller 1. Correspondingly, the arc length of the additional negative pressure air inlet 214 along the circumferential direction of the roller body 22 corresponds to a central angle of 3°-5°, preferably 5°.

[0031] In some embodiments, as shown in Figure 3 the working part 11 includes a rubbing surface 111 provided with a rubbing pattern, and a supporting surface 112 located at both ends of the rubbing surface 111 in the axial direction of the roller body 22, that is, in the front-rear direction according to Figure 1 the rubbing surface 111 is away from the roller body 22. When the cigarette is rubbed, only the middle joint part is subjected to the rolling and rubbing action of the surface of the roller body 22 and the rubbing surface 111, and the two ends of the cigarette cannot be subjected to the extrusion action because they cannot be supported, so as to ensure the quality of the cigarette and further reduce the occurrence of the empty head phenomenon of the cigarette.

[0032] In some embodiments, the length direction of the rubbing pattern is parallel to the axial direction of the roller body 22 to improve the rubbing effect. The depth of the rubbing pattern is controlled to be 0.5mm, and the depth of the pattern is relatively shallow, which is not easy to accumulate dust and reduces the number of cleaning stops.

[0033] In some embodiments, the working part 11 is sequentially provided with a plurality of heating pipes 113 along the circumferential direction of the roller body 22, and the heating power of the plurality of heating pipes 113 is sequentially reduced along the rotation direction of the roller body 22, that is, the heating power is larger closer to the upstream, so as to effectively reduce the temperature fluctuation on the working part 11 to ensure the rubbing quality. In addition, the working part 11 is also provided with a temperature measuring unit 114 to ensure that the rubbing temperature is within an appropriate range. In some embodiments, the temperature measuring unit 114 is arranged at the geometric center of the working part 11, which is conducive to more accurately detecting the temperature of the working part 11 and further reducing the temperature fluctuation on the working part 11.

[0034] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
