[0041] See also Figure 1 and Figure 2The embodiment of the utility model provides a cigarette cutting device, which is used to cooperate with other devices of the cigarette rolling and joining device. It includes a fixed seat assembly 1, a cutter assembly (not shown), a cover assembly 2 and a scraper assembly 3. The fixed seat assembly 1 includes a first seat body 11 and a second seat body 12 fixedly connected to the first seat body 11; the first seat body 11 includes a central hole 111 that runs through its own axial direction, and the second seat body 12 includes a central groove 121 that is connected to the central hole 111. The side and two axial ends of the central groove 121 are open. The opening on the side of the central groove 121 is used to cooperate with other components of the cigarette rolling and joining device. The openings at both ends of the central groove 121 are used to communicate with the central hole 111 at one end and to install the cutter assembly at the other end. The cutter assembly includes a cutter (not shown) and a support assembly (not shown). The cutter is rotatably mounted on the support assembly; the support assembly is mounted in the central groove 121 and / or the central hole 111; part of the edge of the cutter is located outside the central groove 121. The cover assembly 2 is rotatably mounted on the second base 12; the cover assembly 2 and the second base 12 together form a cavity 20 for accommodating the cutter. The scraper assembly 3 is mounted on the cover assembly 2 and / or the second base 12, and the scraper assembly 3 abuts against the surface of the cutter to scrape off the attachments on the surface of the cutter.

[0042] The fixed seat assembly 1 is used to support and install the cutter assembly. The first seat body 11 and the second seat body 12 of the fixed seat assembly 1 can be fixedly connected or adopt a casting structure. The first seat body 11 adopts a cylindrical structure. A center hole 111 is provided at the center of the first seat body 11. The diameter of the center hole 111 is larger than the diameter of the center groove 121 of the second seat body 12. The center groove 121 is a structure formed by a circular hole being cut flat by a plane. The diameter of the center groove 121 refers to the diameter of the circular hole when the center groove 121 is not cut flat by a plane.

[0043] The second seat body 12 adopts a T-shaped structure, and the diameter of the cross section of one end of the second seat body 12 away from the first seat body 11 is larger than the diameter of the cross section of the other end of the second seat body 12 toward the first seat body 11. One end of the second seat body 12 is recorded as the first end, and the other end of the second seat body 12 is recorded as the second end.

[0044] Continue to see Figure 1 or Figure 3In some embodiments, the second seat body 12 further includes a flow channel 122; the flow channel 122 runs through the second seat body 12, and the flow channel 122 extends to the surface of the second seat body 12 facing the cutter. The flow channel 122 is arranged at the first end of the second seat body 12 facing the cutter. The flow channel 122 is used to blow air toward the cutter assembly to reduce the temperature of the cutter assembly and blow off the attachments attached to the surface of the cutter assembly. The flow channel 122 and the scraper assembly 3 cooperate with each other. The scraper assembly 3 removes the attachments on the surface of the cutter assembly by physical contact and scraping, while the flow channel 122 removes the attachments on the surface of the cutter assembly by blowing. The flow channel 122 and the scraper assembly 3 cooperate with each other, and the removal effect is better and cleaner. The temperature of the air blown out of the flow channel 122 can be adjusted to improve the effect of cooling the cutter assembly, so that the temperature of the cutter assembly during operation will not be too high, which is more conducive to reducing the amount of powder generated during the operation of the cutter.

[0045] In some embodiments, there are multiple flow channels 122, and the multiple flow channels 122 are divided into at least two groups, and each group of flow channels 122 faces different positions of the cutter circumference. Several groups of flow channels 122 are dispersedly arranged along the circumference of the central groove 121, and each group of flow channels 122 includes three or more flow channels 122 arranged side by side. The flow channels of each flow channel 122 are independent. By blowing airflow to the surface of the cutter assembly through the flow channels 122, the attachments at different positions of the cutter assembly can be blown away at the same time.

[0046] Continue to see Figure 3 In some embodiments, at least one flow channel 122 is configured to be variable in diameter, and the diameter of the end of the flow channel 122 facing the cutter is smaller than the diameter of the other end of the flow channel 122 away from the cutter. All flow channels 122 can be configured to be variable in diameter. The variable-diameter flow channels 122 greatly increase the airflow per unit time and per unit area, and can effectively clean the blade surface while reducing the temperature of the slitting blade. At the same time, the three-point layout can improve the cleaning and cooling effects. The airflow is shot at the blade surface at a higher speed, which has a cooling effect, and is also conducive to improving the quality of cigarette cutting and removing attachments to the cutter assembly.

[0047] During the operation of the cutter assembly, since the material cut by the cutter is a cigarette, some powdery debris will be generated, and these debris may accumulate in the cavity 20 surrounded by the fixed seat assembly 1 and the cover assembly 2. In order to prevent too much debris in the cavity 20 from affecting the normal operation of the cutter assembly, in some embodiments, the second seat body 12 is also provided with a collection groove 123, and the collection groove 123 is connected to the cavity 20. The collection groove 123 is a groove formed on the top surface of the second seat body 12, and the collection groove 123 and the center groove 121 are dispersedly arranged, and the two are not connected. The collection groove 123 is connected to the cavity 20 where the cutter is located. The size of the collection groove 123 is much smaller than the diameter of the center groove 121, and the collection groove 123 is easy to store debris. The cigarette cutting device also includes a negative pressure providing device, which is connected to the collection groove 123 to collect the debris generated during the operation of the cutter. During the operation of the cutter assembly, the negative pressure providing device works in real time and provides negative pressure in real time. The negative pressure is used to promptly suck away the debris in the cavity 20 from the collecting groove 123, so that the debris hardly stays in the collecting groove 123, keeping the interior of the cavity 20 clean.

[0048] Continue to see Figure 1 In some embodiments, the scraper assembly 3 includes a first scraper 31 and a second scraper 32. The first scraper 31 is installed on the side of the cover assembly 2 facing the second base 12, and the first scraper 31 is located on the side of the cutter away from the second base 12. The second scraper 32 is installed on the second base 12, and the second scraper 32 is located on the side of the cutter away from the cover assembly 2. The first scraper 31 and the second scraper 32 can both adopt a narrow sheet structure, and the first scraper 31 and the second scraper 32 only need to lightly abut the surface of the cutter to remove the cigarette debris attached to the surface of the cutter.

[0049] See also Figure 1 The first scraper 31 and the second scraper 32 are both made of elastic material and are both constructed as a bent sheet structure. One end of the first scraper 31 is detachably connected to the cover assembly 2, and the other end of the first scraper 31 is tilted toward the cutter assembly to contact the cutter assembly. One end of the second scraper 32 is detachably connected to the second base 12, and the other end of the second scraper 32 is also tilted toward the cutter assembly to contact the cutter assembly. The first scraper 31 and the second scraper 32 clamp the cutter.

[0050] The first scraper 31 and the second scraper 32 are both located in the cavity 20 surrounded by the fixing seat assembly 1 and the cover assembly 2. The first scraper 31 and the second scraper 32 are symmetrically arranged relative to the cutter. In this way, the force of the first scraper 31 and the second scraper 32 on the cutter during operation is more balanced, and the cutter will not deviate under the action of the symmetrically distributed first scraper 31 and the second scraper 32.

[0051] Back to Figure 1In some embodiments, the cover assembly 2 includes a cover body 21, and the cover body 21 includes a side wall and a bottom wall; the side wall is constructed to be annular and transparent; the bottom wall is installed in the annular through hole surrounded by the side wall.

[0052] A matching step is provided on the circumferential edge of one end of the second seat body 12 away from the first seat body 11 , and the cover body 21 can be opened and closed on the matching step 124 of the second seat body 12 by a hinge, thereby improving the matching accuracy and the airtightness.

[0053] The cover assembly 2 and the fixing seat assembly 1 form a closed cavity 20 protective cover, which protects the cutter and reduces or even avoids the influence of powder and other substances generated by slitting on other parts, while isolating external influences, improving cutting quality, and improving the protection of operators during slitting operations.

[0054] The side wall of the cover body 21 can be made of transparent material, or at least the part facing the personnel can be made of transparent material, such as plexiglass, so that the operator can observe the working conditions of each component in the cavity 20 in real time, and deal with abnormal situations in time when they occur, such as scraper damage, collection tank 123 being blocked, flow channel 122 not producing air, etc.

[0055] Continue to see Figure 1 In some embodiments, the cover assembly 2 further includes a handle 22, which is mounted on a side of the cover 21 away from the fixing base assembly 1; the handle 22 includes a hand grip for opening and closing the cover 21. The cover assembly 2 and the fixing base assembly 1 are hinged, and the hinge is approximately 180° from the handle 22. The handle 22 is disposed at the farthest point of the hinge between the cover assembly 2 and the fixing base assembly 1, so as to facilitate the operation of the handle 22 to open and close the cover assembly 2.

[0056] The embodiment of the utility model further provides a cigarette rolling and joining device, comprising the cigarette cutting device provided by any technical solution of the utility model.

[0057] The embodiment of the utility model further provides a cigarette cutting method, which is implemented by using the cigarette cutting device provided by any technical solution of the utility model. The cigarette cutting method includes the following steps:

[0058] First, the cutter assembly is started to cut cigarettes; during the rotation of the cutter of the cutter assembly, the cutter and the scraper assembly 3 move relative to each other, so that the scraper assembly 3 removes the attachments on the surface of the cutter.

[0059] Secondly, the flow channel 122 of the cigarette cutting device is opened to blow air to the surface of the cutter. The air is used to cool down and clean the cutter.

[0060] Next, the negative pressure providing device of the cigarette cutting device is started to collect the debris generated during the operation of the cutter.

[0061] It should be noted that the step of starting the cutter assembly can be performed simultaneously with the action of opening the flow channel 122 and starting the negative pressure providing device, so that the cigarette cutting, cooling and dust removal can be carried out simultaneously.
