[0002] With the expansion of market demand for medium and thin cigarettes, it is becoming more and more common across the country to convert conventional cigarette-making machines into medium and thin cigarette-making machines.

[0003] The inventors have discovered that there are at least the following problems in the prior art: a conventional cigarette-making machine is modified into a medium-slim cigarette-making machine, and its structure is similar to that of a conventional cigarette-making machine, but the structures of conventional cigarettes and medium-slim cigarettes are different, resulting in severe wear of the sealing cap at the filter end of the modified medium-slim cigarette-making machine. Utility Model Content

[0004] The utility model provides a detection drum and a medium-thin cigarette making machine, which are used to reduce the wear of a sealing cap at a filter tip end.

[0005] The present invention provides a detection drum, comprising:

[0006] The drum body is provided with a plurality of drum grooves along its circumference;

[0007] A first detection ring includes a plurality of first mounting portions; the first detection ring is mounted on the drum body;

[0008] A second detection ring includes a plurality of second mounting portions; the second detection ring is mounted on the drum body;

[0009] a plurality of first detection caps, mounted on the first mounting portion in a one-to-one correspondence; and

[0010] A plurality of second detection caps are mounted on the second mounting portion in a one-to-one correspondence;

[0011] Wherein, the free ends of the first detection cap and the second detection cap are both flat.

[0012] In some embodiments, the first detection cap and the second detection cap have the same structure.

[0013] In some embodiments, the detection drum further comprises:

[0014] an air supply path, mounted on the drum body;

[0015] The first detection cap includes a first air hole running through the first detection cap in its axial direction, and the first air hole is connected to the air supply path.

[0016] In some embodiments, the second detection cap includes a second air hole running through the second detection cap in its axial direction, and the second air hole is also connected to the air supply path.

[0017] In some embodiments, the first detection cap and the second detection cap are arranged in a one-to-one correspondence.

[0018] In some embodiments, there is a gap between the first detection ring and the second detection ring, and the gap is configured to accommodate a medium-thin cigarette to be detected.

[0019] In some embodiments, the first detection ring is rotatably mounted on the drum body.

[0020] In some embodiments, the second detection ring is rotatably mounted on the drum body.

[0021] In some embodiments, a plurality of first mounting portions are evenly distributed along the circumference of the first detection ring, and / or a plurality of second mounting portions are evenly distributed along the circumference of the second detection ring.

[0022] An embodiment of the present invention further provides a medium-thin cigarette making machine, comprising the detection drum provided by any technical solution of the present invention.

[0023] The detection drum provided by the above technical solution includes a drum body, a first detection ring and a second detection ring mounted on the drum body, a first mounting portion mounted on the first detection ring, and a second mounting portion mounted on the second detection ring. A first detection cap is mounted on the first detection ring, and a second detection cap is mounted on the second detection ring. The free ends of the first detection cap and the second detection cap are both flat. The detection drum detects medium-thin cigarettes, which are longer and thinner in diameter than regular cigarettes. The medium-thin cigarettes are sandwiched between the first detection cap and the second detection cap. Both the first detection cap and the second detection cap are flat, so the forces acting on both ends of the medium-thin cigarettes are relatively balanced. The friction between the medium-thin cigarette and the first detection cap, as well as the friction between the medium-thin cigarette and the second detection cap, is relatively balanced. The wear of the first detection cap corresponding to the filter end of the medium-thin cigarette will not be affected by the high friction between the medium-thin cigarette and one of the detection caps, and the wear is effectively reduced. It can be seen that the above technical solution reduces the wear of the first detection cap and the second detection cap caused by medium and thin cigarettes during the detection process of medium and thin cigarettes, so that the first detection cap and the second detection cap can work normally, and can extend the service life of the first detection cap corresponding to the filter end of the medium and thin cigarettes, reduce the company's spare parts consumption, reduce the consumption of medium and thin cigarettes, and improve the operating efficiency of the equipment.

[0040] See also Figures 1 to 4 The present invention provides a detection drum for detecting medium-thin cigarettes 9. The size of the medium-thin cigarettes 9 uses existing parameters. The medium-thin cigarettes 9 include a filter end 91 and a tobacco end 92.

[0041] The detection drum comprises a drum body 1, a first detection ring 2, a second detection ring 3, a plurality of first detection caps 4 and a plurality of second detection caps 5. The drum body 1 is provided with a plurality of drum grooves 11 along its circumference.

[0042] The first detection ring 2 includes a plurality of first mounting portions 21 ; the first detection ring 2 is mounted on the drum body 1 .

[0043] The second detection ring 3 includes multiple second mounting portions 31; the second detection ring 3 is mounted on the drum body 1. Multiple first detection caps 4 are mounted one-to-one on the first mounting portions 21. Multiple second detection caps 5 are mounted one-to-one on the second mounting portions 31. The free ends of the first detection caps 4 and the second detection caps 5 are both flat.

[0044] See also Figure 1The detection drum includes a drum body 1, which is the rotatable portion of the detection drum. A first detection ring 2 and a second detection ring 3 are mounted on the drum body 1. The drum body 1 is positioned between the first detection ring 2 and the second detection ring 3. The drum body 1 is provided with a plurality of drum grooves 11 on its circumferential outer surface, specifically 36, for example. Each drum groove 11 is inwardly recessed and open, with its length aligned along the axis of the first detection ring 2 and the second detection ring 3.

[0045] The number of the first detection caps 4 installed on the first detection ring 2 is the same as the number of the drum grooves 11 of the drum body 1 , and the number of the second detection caps 5 installed on the first detection ring 2 is also the same as the number of the drum grooves 11 of the drum body 1 , both of which are 36.

[0046] In some embodiments, the first detection cap 4 and the second detection cap 5 have the same structure. In some embodiments, the first detection cap 4 and the second detection cap 5 are arranged in a one-to-one correspondence. A first detection cap 4 is provided at one end of each drum groove 11, and a second detection cap 5 is provided at the other end of each drum groove 11.

[0047] In some embodiments, the first detection ring 2 is rotatably mounted on the drum body 1. The second detection ring 3 is rotatably mounted on the drum body 1. There is a gap between the first detection ring 2 and the second detection ring 3, and the gap is configured to accommodate a medium-thin cigarette 9 to be detected.

[0048] In some embodiments, the inspection drum further includes an air supply path 6 mounted on the drum body 1. The first inspection cap 4 includes a first air hole extending axially therethrough, the first air hole communicating with the air supply path 6. In some embodiments, the second inspection cap 5 includes a second air hole extending axially therethrough, the second air hole also communicating with the air supply path 6.

[0049] The test air is delivered to the test drum's test sector 8 through the hose 7 connecting joint. The test air then passes from the test sector 8 through the holes in the test ring slot to the first air hole of the first test cap 4 and the second air hole of the second test cap 5.

[0050] When the detection drum receives a medium-thin cigarette 9, it is positioned between the first detection ring 2 and the second detection ring 3. The distance between the medium-thin cigarette 9 and the first and second detection caps 4 and 5 is very small. To allow the detection caps to be pushed or pressed toward the ignition end via the filter end 91 as the detection drum rotates, the first and second detection rings 2 and 3 operate at a very small angle relative to the drum body 1. When the detection drum reaches its highest point, the distance between the first and second detection caps 4 and 5 is minimized. The first detection cap 4 faces the filter end 91 of the medium-thin cigarette 9, while the second detection cap 5 faces the tobacco end 92, also known as the ignition end, of the medium-thin cigarette 9.

[0051] During the transition from detecting to receiving medium-thin cigarettes 9, the inclination between the drum 1 and the first and second detection rings 2 and 3 allows the filter end 91 of the medium-thin cigarette 9 to be pushed into the first detection cap 4. The first detection cap 4 includes a sealing mechanism. The pressure exerted by the medium-thin cigarette 9 on the first detection cap 4 causes the protruding collar of the detection cap to enclose the filter end 91 of the medium-thin cigarette 9 and seal it.

[0052] Since the height of the first detection cap 4 is about 0.5 cm higher than that of the second detection cap 5, and the friction area between the medium-thin cigarette 9 and the side of the first detection cap 4 when entering the detection drum is larger than that between the first detection cap and the ignition end detection cap, the structures of the first detection cap 4 and the second detection cap 5 are exactly the same. When the equipment is running, the edge area of the first detection cap 4 in contact with the filter of the medium-thin cigarette 9 is similar to the edge area of the second detection cap 5 in contact with the tobacco end 92 of the medium-thin cigarette 9. Both the first detection cap 4 and the second detection cap 5 are not easy to wear, which can ensure that the sealing performance of the filter end 91 of the medium-thin cigarette 9 is not reduced. Therefore, there is no need to frequently replace the first detection cap 4 and the second detection cap 5. The tightness test, air permeability test and draw resistance test values of the CIS detection system of the medium-thin cigarette 9 cigarette making machine are relatively normal, the rejection rate of medium-thin cigarettes 9 is low, and the production efficiency is relatively high.

[0053] In some embodiments, a plurality of first mounting portions 21 are evenly distributed along the circumference of the first detection ring 2 ; and / or a plurality of second mounting portions 31 are evenly distributed along the circumference of the second detection ring 3 .

[0054] The first detection cap 4 of the first detection ring 2 and the second detection cap 5 of the second detection ring 3 have the same structure. The first detection cap 4 is equipped with a sealing mechanism released by the medium and thin cigarettes 9 to ensure the required tightness of the medium and thin cigarettes 9.

[0055] During use, the detection drum is adjusted in the following manner.

[0056] While the inspection drum is running, disable the compactness rejection, total air permeability rejection, and draw resistance rejection functions of the CIS inspection system of the medium-slim cigarette maker. Start the machine for a test run and check whether the ends of the medium-slim cigarettes 9 output from the inspection drum are wrinkled. If wrinkles are present, increase the distance between the first inspection ring 2 and the second inspection ring 3. After adjustment, restart the machine and check the condition of the medium-slim cigarettes 9 again until the ends of the medium-slim cigarettes 9 output from the inspection drum are normal and wrinkle-free.

[0057] After the distance between the first detection ring 2 and the second detection ring 3 is adjusted to the desired position, the detection values of tightness, total air permeability and suction resistance in the CIS detection system are observed, and the detection values after stable operation are set as set values.

[0058] Re-enable the tightness rejection function, total air permeability rejection function and suction resistance rejection function of the CIS detection system.

[0059] Observe the rejection situation and sample medium-thin cigarettes 9 that fail to meet the standards for tightness, total air permeability, and draw resistance. If the sampled medium-thin cigarettes 9 contain qualified medium-thin cigarettes 9, the accuracy of sampling unqualified medium-thin cigarettes 9 can be improved by adjusting the corresponding rejection limit value.

[0060] The above technical solution extends the service life of the first detection cap 4 corresponding to the filter end 91 of the medium and thin cigarette 9, reduces the consumption of the first detection cap 4, reduces the rejection caused by abnormalities in the tightness, air permeability and draw resistance tests in the CIS detection system, and improves the production efficiency of the medium and thin cigarette making machine.

[0061] An embodiment of the present invention further provides a 9-medium-thin cigarette making machine, comprising the detection drum provided by any technical solution of the present invention.
