[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example:

[0024] Combined with attachment Figure 1 As shown, a feed roller device of a comprehensive cigarette tester includes a feed roller 1, a thin baffle 3 and a plucking roller 5 arranged in a feed unit 7 of the comprehensive cigarette tester. A plurality of axial grooves 6 are evenly distributed on the surface of the feed roller 1. The length of the groove 6 is the same as the axial length of the feed roller and the specifications of the plurality of grooves are completely consistent. A thin baffle 3 is obliquely provided above the feed roller 1 and contacts the outer surface of the feed roller to prevent more than one cigarette from being accommodated in the groove. The plucking roller and the thin baffle are arranged on the same side of the feed roller. The plucking roller and the feed roller are connected by a multi-stage belt, and the gap between the plucking roller and the feed roller is not larger than the diameter of the cigarette to prevent the cigarette in the groove from slipping through the gap between the plucking roller and the feed roller.

[0025] One end of the thin baffle 3 is located in the middle of the feed roller, and the other end is fixed to the feed unit 7 of the cigarette tester above the plucking roller. The plucking roller 5 is also set in the feed unit 7 of the cigarette tester and is located in the upper front of the feed roller's rotation direction. It is connected to the feed roller 1 through a multi-stage belt, and there is a certain gap between it and the feed roller. During operation, the cigarette is placed in the feed unit 7 of the tester. As the feed roller 1 rotates, it falls into the groove 6 on the surface of the feed roller and rotates clockwise with the feed roller. At this time, under the action of the multi-stage belt transmission, the plucking roller also rotates in the same direction. When the feed roller groove with the cigarette passes the plucking roller, the cigarette falls out of the groove and enters the main body 9 of the tester, and then the subsequent measurement of the physical indicators of the cigarette begins.

[0026] Preferably, the end of the thin baffle in contact with the feed roller is located at the vertical center line of the feed roller or at the side of the vertical center line of the feed roller away from the pulling roller, so that the thin baffle can prevent the groove from accommodating more than one cigarette.

[0027] Further, such as Figure 2As shown, the comprehensive tester includes: a comprehensive tester main body 9, a comprehensive tester feeding unit 7 arranged above the comprehensive tester main body 9, and a comprehensive tester touch display screen arranged on the side of the comprehensive tester main body 9. Cigarettes enter the comprehensive tester main body through the cigarette comprehensive tester feeding unit, and the comprehensive tester is controlled through the comprehensive tester touch display screen.

[0028] like Figure 1 As shown, the integrated tester's feed unit 7 comprises an outer frame 4 housing a feed roller 1, a thin baffle 3, and a draw roller 5. The distance between the feed roller 1 and the left side of the outer frame 4 is less than the diameter of any cigarette to prevent cigarettes from falling through the gap between the feed roller 1 and the left side of the outer frame 4. Preferably, the feed roller 1 is positioned against the left side of the outer frame 4. Similarly, the distance between the feed roller 1 and the draw roller 5 is less than the diameter of any cigarette.

[0029] The outer frame of the feed unit includes a left side plate 10 and an outer frame mounting plate 11. The left side plate 10 is preferably positioned against the feed roller 1 to prevent cigarettes from entering the main body 9 of the integrated tester through the gap between the left side plate 10 and the feed roller 1. The mounting plate 11 is located to the upper right of the feed roller 1 and is used to mount the thin baffle 3 and limit the position of the draw roller 5, preventing it from getting too close to the feed roller 1.

[0030] In a specific embodiment, referring to the attached Figure 3 The radius of the groove is R1 = 5mm, the distance from the bottom of the groove to the top of the groove is L = 8.20mm, the distance from the vertical center line of the groove to the edge of the groove is L1 = 3.95mm, and the distance from the top of the cigarette to the top of the groove is h; the radius of the cigarette is R2, when the cigarette is a medium cigarette, R 2中 =3.18mm, when the cigarette is a slim cigarette, R 2细 = 2.70mm. In both cases, 2*R2> the distance L1 from the vertical centerline of the groove to the edge of the groove. Therefore, neither medium nor thin cigarettes can enter the groove through the gap between the thin baffle and the groove. This can prevent excess cigarettes from entering the groove. In addition, when feeding medium cigarettes, the distance h from the top of the cigarette to the top of the groove is L-2*R. 2中 =8.20-2*3.18=1.84mm<2*R2; when feeding slim cigarettes, h=L-2*R 2细 =8.20-2*2.70=2.80mm<2*R2; that is, 2*R2>the distance h between the top of the cigarette and the top of the groove, that is, L-2*R2<2*R2, that is, L<4*R2. Due to the obstruction of the thin baffle, the groove cannot accommodate more than one cigarette, so that there is only one cigarette in the groove to avoid cigarette jamming.

[0031] In this way, through the combined action of the feed roller and the thin baffle, excess cigarettes can be prevented from entering the groove of the feed roller and the gap between the feed roller and the pulling roller, thereby avoiding cigarette jamming during feeding. This structure is suitable for cigarettes with a circumference length of less than or equal to 20mm, and the groove radius R1 range is: 4.8mm≤R1≤5.2mm.

[0032] In this embodiment, three grooves are provided and are evenly distributed on the outer surface of the feed roller.

[0033] Preferably, the edges of the groove and the thin baffle are both chamfered to prevent damage to the cigarettes. Furthermore, the integrated tester's feed unit 7 is tilted to the left, away from the thin baffle, to encourage the cigarettes to roll away from the baffle. This prevents more than one cigarette from remaining in the same groove due to the baffle's blocking effect.

[0034] Specific workflow:

[0035] After the cigarette 2 is placed into the feeding unit 7 of the comprehensive tester in a certain direction, the measurement process is started through the touch screen display 8 of the comprehensive tester. The feed roller 1 and the pulling roller 5 will rotate clockwise together. During the rotation of the feed roller 1, the cigarette automatically rolls into the groove 6 of the feed roller 1 and rotates with the feed roller 1. At this time, the excess cigarettes will be blocked by the thin baffle 3 or pushed out of the groove 6 to prevent them from passing through the groove 6 into the gap between the feed roller 1 and the pulling roller 5. When the groove 6 with the cigarette 2 passes the pulling roller 5, the groove 6 tilts downward, and the cigarette falls from the groove 6 and enters the main part 9 of the comprehensive tester, thereby completing the feeding process.

[0036] Before the adoption of the feed roller device of the present invention's integrated cigarette detector, the SODIM integrated cigarette detector needed to switch the grooves on the feed roller when measuring cigarettes of different sizes. When the groove switching was inaccurate or a cigarette rolled into the gap between the feed roller and the pull roller, a cigarette jam would occur, affecting the smooth progress of cigarette measurement. The entire process was time-consuming and labor-intensive. After adopting the feed roller device of the present invention's integrated cigarette detector, the new feed roller can easily feed medium and thin cigarettes without switching, and the combination of the thin baffle and feed roller can prevent cigarettes from entering the gap between the feed roller and the pull roller, thereby avoiding cigarette jams during the feeding process and ultimately achieving fast and efficient cigarette feeding.

[0037] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
