[0031] Accurate measurement of process dust removal volume on individual cigarette manufacturing machines is a major challenge in cigarette production. Currently, dust removal systems are commonly used to clean the cigarette manufacturing machines. Typically, multiple machines share a single dust removal system. However, during maintenance, verification, and performance testing of cigarette manufacturing machines, it is impossible to accurately measure the process dust removal waste from individual machines, thus hindering the evaluation of the machine's production status based on process dust removal volume.

[0032] To address the aforementioned problems, this application provides a process dust collection device and a cigarette-making machine. The process dust collection device includes a support member, a limiting member, and a filter element. The first cylindrical body of the support member can be embedded into the air intake of the cigarette-making machine, and the second cylindrical body of the limiting member extends into the interior of the first cylindrical body. The filter element is sandwiched between the support member and the limiting member, and covers the interior of the first cylindrical body. When the air intake of the cigarette-making machine is connected to the dust collection device, the filter element can intercept waste such as dust. After a preset production time, the process dust collection device can be removed, and the intercepted dust can be weighed to obtain the total process dust collected by a single cigarette-making machine over the preset time, and the process dust collection rate per minute of a single cigarette-making machine can be calculated. This effectively provides input for evaluating the operating conditions of the cigarette-making machine, the state of the suction line, and other dimensions.

[0033] The specific structure of the process dust collection device provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0034] Reference Figures 1 to 4 As shown in the figure, this application provides a process dust collection device, which is connected to the air inlet of a cigarette machine and includes a support 100, a limiting member 200 and a filter.

[0035] The support member 100 includes a first cylindrical body 110, which is configured to be embedded within the air intake of the cigarette machine. Those skilled in the art will understand that the outside of the air intake is connected to a dust removal system via a pipe, and the negative pressure provided by the dust removal system causes the tobacco inside the cigarette machine to be adsorbed onto the suction belt. Generally, the air intake is irregularly shaped, and the cross-sectional shape of the first cylindrical body 110 matches the cross-sectional shape of the air intake. The fit between the first cylindrical body 110 and the air intake facilitates the positioning of the support member 100 and the cigarette machine.

[0036] A limiting member 200 is mounted on the support member 100. The limiting member 200 includes a second cylindrical body 210 that extends into the interior of the first cylindrical body 110. The cross-sectional shape of the second cylindrical body 210 matches the cross-sectional shape of the first cylindrical body 110. Schematic, when the second cylindrical body 210 is inserted into the first cylindrical body 110, its outer surface abuts against the inner surface of the first cylindrical body 110. This engagement between the second cylindrical body 210 and the first cylindrical body 110 facilitates the positioning of the limiting member 200 and the support member 100.

[0037] The filter element is held between the support member 100 and the limiting member 200, and covers the interior of the first cylinder 110. Understandably, when the dust removal equipment draws gas from the cigarette machine, this gas passes through the filter element, which filters out dust and other waste carried by the gas.

[0038] For example, the filter element can be a filter screen, a cylindrical filter bag, or a conical filter bag, etc., which can be selected according to production and process requirements. After the process dust collection device is installed on the cigarette machine, the dust collection equipment can provide negative pressure to the inside of the cigarette machine through the interior of the second cylinder 210. When the dust collection equipment provides negative pressure to the inside of the cigarette machine, the filter element can intercept waste.

[0039] It is worth mentioning that the filter element can also intercept tobacco shreds, preventing them from being sucked into the dust removal equipment and reducing material waste.

[0040] It should be noted that during the production process of cigarette making machines, various types of dust are generated (process dust, pneumatic dust, and stem / fiber removal). These various dust materials are drawn into the dust collection equipment through different air inlets. In previous production processes, the dust collection volume measurement of cigarette making machines could only measure the total amount of dust (process dust, pneumatic dust, and stem / fiber removal) from multiple machines, indirectly reflecting the process dust collection volume. The process dust collection device provided in this application embodiment can be multiple and installed at different air inlets of the cigarette making machine, thereby intercepting different dust materials from a single machine.

[0041] The process dust collection device provided in this embodiment enables accurate detection of the process dust removal volume of a single cigarette rolling machine. Before production begins, the process dust collection device is installed at the air intake of the cigarette rolling machine. After a production period T, the process dust collection device is removed, and the trapped dust is weighed to obtain the total process dust removal volume for period T. The process dust removal volume per minute of the tested cigarette rolling machine can then be calculated. This effectively provides input for evaluating the operating conditions and air intake status of the cigarette rolling machine.

[0042] The process dust collection device provided in this embodiment, based on the appearance and structural features of the cigarette machine's air intake, and in accordance with the mechanical structure, achieves low-cost interception and detection of process dust in cigarette machines. It is also easy to install and can be used with multiple models.

[0043] In one embodiment, such as Figures 1-4 As shown, the end of the second cylinder 210 is provided with an outwardly extending flange 220, which abuts against the end of the first cylinder 110.

[0044] The flange 220 is located at the end of the second cylinder 210 facing the inside of the cigarette machine, and abuts against the end of the first cylinder 110 facing the inside of the cigarette machine. Schematably, the flange 220 is formed into a ring structure, which surrounds the end of the second cylinder 210. The second cylinder 210 and the flange 220 can be integrally formed into a single piece.

[0045] Understandably, through the cooperation between the flange 220 and the first cylinder 110, when the support member 100 is connected to the cigarette machine, the first cylinder 110 of the support member 100 can limit the limiting member 200, ensuring that the limiting member 200 will not be sucked into the pipeline between the cigarette machine and the dust removal equipment under the negative pressure provided by the dust removal equipment, and the filter between the support member 100 and the limiting member 200 can reliably intercept waste.

[0046] In a specific embodiment, such as Figures 1-4 As shown, an annular groove 111 is provided at the end of the first cylinder 110, and an annular protrusion 221 is provided on the side of the flange 220 facing the first cylinder 110. The annular protrusion 221 extends into the interior of the annular groove 111, and part of the filter element is clamped between the annular protrusion 221 and the annular groove 111.

[0047] For example, the annular groove 111 can be integrally formed on the end of the first cylinder 110 facing the inside of the cigarette machine, and the annular groove 111 is arranged around the axis of the first cylinder 110. The annular protrusion 221 can be integrally formed on the flange 220, and the annular protrusion 221 is arranged around the second cylinder 210. The shape and size of the longitudinal section of the annular protrusion 221 match the longitudinal section of the annular groove 111.

[0048] In this embodiment, the filter element is clamped by the annular groove 111 and the annular protrusion 221 extending into the annular groove 111, which improves the reliability of the filter element fixation, avoids displacement of the filter element during use of the process dust collection device, and ensures the reliability of the filter element's interception.

[0049] In a specific embodiment, such as Figures 1-4 As shown, the outer periphery of the first cylinder 110 is provided with an inwardly recessed first cut 112, and the outer periphery of the flange 220 is provided with an inwardly recessed second cut 222, the position of the second cut 222 being directly opposite the first cut 112.

[0050] Along the axial direction of the first cylinder 110, the size of the first cut 112 is the same as the size of the first cylinder 110, and the size of the second cut 222 is the same as the size of the flange 220. When the limiting member 200 is connected to the support member 100, the projection of the second cut 222 along the axial direction of the first cylinder 110 coincides with the projection of the first cut 112 along the axial direction of the first cylinder 110.

[0051] With the above configuration, after the process dust collection device is installed on the cigarette machine, the support member 100 can avoid other parts of the cigarette machine through the first cut 112, and the limiting member 200 can avoid other parts of the cigarette machine through the second cut 222, so as to avoid interference between the process dust collection device and other parts of the cigarette machine (such as the metal beam above the air inlet), and the installation of the process dust collection device is convenient.

[0052] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, a first limiting part 120 is provided on the outer side wall of the end of the first cylinder 110, and the first limiting part 120 is configured to abut against the wall of the cigarette machine.

[0053] Schematic illustration: the first limiting part 120 can be a sheet-like structure, one end of which is connected to the first cylinder 110. The first limiting part 120 and the first cylinder 110 can be formed as a single piece using an integral molding process. When the process dust collection device is installed on the cigarette machine, the side of the first limiting part 120 abuts against the side of the cigarette machine wall facing inwards.

[0054] Understandably, the outer diameter of the first cylinder 110 is slightly smaller than the inner diameter of the air inlet, and the total size of the first cylinder 110 and the first limiting part 120 is larger than the size of the air inlet, so as to ensure that the first limiting part 120 can reliably abut against the wall of the cigarette machine.

[0055] With the above settings, the support member 100 can be reliably limited by the cooperation between the first limiting part 120 and the wall of the cigarette machine, ensuring that the support member 100 will not be sucked into the pipeline between the cigarette machine and the dust removal equipment under the negative pressure provided by the dust removal equipment.

[0056] In a specific embodiment, such as Figures 1-4 As shown, the limiting member 200 is provided with a second limiting part 230, and the first limiting part 120 and the second limiting part 230 are fastened together by fasteners, which pass through the filter element.

[0057] Schematic illustration: the second limiting part 230 is a sheet-like structure. When the limiting member 200 is installed on the support member 100, the second limiting part 230 and the first limiting part 120 are arranged parallel to each other, and part of the filter element is sandwiched between the second limiting part 230 and the first limiting part 120. Specifically, after the limiting member 200 is installed on the support member 100, the projection of the second limiting part 230 along the axial direction of the first cylinder 110 coincides with the projection of the first limiting part 120 along the axial direction of the first cylinder 110.

[0058] like Figures 1-3 As shown, the first limiting part 120 has a first fastening hole 121, and the second limiting part 230 has a second fastening hole 231. After the limiting member 200 is installed on the support member 100, the first fastening hole 121 and the second fastening hole 231 are coaxial. After the second cylinder 210 of the limiting member 200 extends into the first cylinder 110 of the support member 100, a fastener is used to pass through the second fastening hole 231 and lock it with the first fastening hole 121 to achieve the fixation between the limiting member 200 and the support member 100. At the same time, the fastener between the first limiting part 120 and the second limiting part 230 passes through the filter element, and the filter element can be further limited by the fastener. The second limiting part 230 and the first limiting part 120 can be fixed by one fastener or by multiple fasteners, which is not limited here.

[0059] In a more specific embodiment, there are two first limiting parts 120, which are located on opposite sides of the first cylinder 110, and there are two second limiting parts 230, which are fastened to the two first limiting parts 120 by fasteners.

[0060] like Figure 1As shown, two first limiting parts 120 are located on the left and right sides of the first cylinder 110, respectively, and two second limiting parts 230 are located on the left and right sides of the limiting member 200, respectively. The left first limiting part 120 and the left second limiting part 230 are fastened together by fasteners, and the right first limiting part 120 and the right second limiting part 230 are fastened together by fasteners. The distance between the opposite ends of the two first limiting parts 120 is greater than the inner diameter of the air intake.

[0061] In this embodiment, after the process dust collection device is installed on the cigarette machine, the two first limiting parts 120 abut against the wall of the cigarette machine, which ensures that the force on the support 100 is more even, and further ensures that the limiting part 200 will not be sucked into the pipeline between the cigarette machine and the dust collection equipment under the negative pressure provided by the dust collection equipment. The two second limiting parts 230 of the limiting part 200 are fastened to the two first limiting parts 120 by fasteners. On the one hand, this ensures that the limiting part 200 is evenly stressed, preventing the limiting part 200 from being sucked into the pipeline between the cigarette machine and the dust collection equipment. On the other hand, the above arrangement increases the number of fasteners between the limiting part 200 and the support 100, and each fastener passes through the filter element, further improving the reliability of the filter element's fixation.

[0062] Specifically, such as Figures 1-4 As shown, along the radial direction of the first cylinder 110, one of the first limiting portions 120 is larger than the other first limiting portion 120, and one of the second limiting portions 230 is larger than the other second limiting portion 230. The larger first limiting portion 120 and the larger second limiting portion 230 are located on the same side of the first cylinder 110.

[0063] For example Figure 1 As shown, the size of the left first limiting portion 120 is smaller than the size of the right first limiting portion 120, and the size of the left second limiting portion 230 is smaller than the size of the right second limiting portion 230. When the limiting member 200 is connected to the support member 100, the smaller first limiting portion 120 and the smaller second limiting portion 230 are located on one side of the first cylinder 110, and the larger first limiting portion 120 and the larger second limiting portion 230 are located on the other side of the first cylinder 110.

[0064] In this embodiment, the small-sized first limiting part 120 and the small-sized second limiting part 230 facilitate the process dust collection device to avoid other parts of the cigarette machine, while the large-sized first limiting part 120 and the large-sized second limiting part 230 are easy for workers to hold, thereby facilitating the installation and disassembly of the process dust collection device.

[0065] In one possible implementation, the inner wall of the first cylinder 110 is provided with an internal thread, and the outer wall of the second cylinder 210 is provided with an external thread, and the first cylinder 110 and the second cylinder 210 are threadedly connected.

[0066] There is a certain gap between the internal thread of the first cylinder 110 and the external thread of the second cylinder 210, and part of the filter element is clamped between the first cylinder 110 and the second cylinder 210.

[0067] With the above settings, the limiting member 200 can be easily fixed to the support member 100, which is beneficial to improving the assembly efficiency of the process dust collection device.

[0068] This embodiment also provides a cigarette making device, including a cigarette making machine and the above-mentioned process dust collection device. An air intake is provided on the wall of the cigarette making machine, and the first cylinder 110 of the process dust collection device is embedded in the air intake.

[0069] The cigarette rolling equipment provided in this embodiment, by employing the aforementioned process dust collection device, can accurately obtain the process dust removal amount of a single cigarette rolling machine, and the production condition of the cigarette rolling machine can be accurately evaluated through the process dust removal amount.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
