Description

Technical Field

[0001] The present invention relates to the technical field of tobacco and cigarette processing machinery engineering, and more particularly to a system for orderly heating cigarette filter rods and cigarette cutting. Background Art

[0002] With the intensification of global tobacco control efforts and growing public health awareness, major multinational tobacco companies have successively developed and launched new tobacco products with lower harm. Among them, heated cigarettes have become a new research hotspot in the tobacco industry. The structure of heated cigarettes is similar to that of traditional cigarettes, consisting of a tobacco core segment and a filter rod. Although research on traditional cigarette filter rods is extensive, heated cigarettes, as a new tobacco product, have a different smoke aerosol generation mechanism than traditional cigarettes, and their physical and chemical characteristics are significantly different from those of traditional cigarettes. The composite filter rods of heated cigarettes are often composed of base rods made of different materials such as hollow acetate fiber, polylactic acid, acetate fiber, and Venturi properties. The physical properties of the filter rods are significantly different from those of traditional filter rods, resulting in significant differences in the cutting characteristics of the filter rods.

[0003] At present, in the production process of orderly heated cigarette equipment, due to changes in the physical properties of cigarettes and filter rods, the cutter is prone to frequent knife disc and filter tip cutter cuts during the filter rod and cigarette cutting process, and filter rod and cigarette dust will accumulate on the cutter disc. Although alloy blades are used after the transformation and upgrading of key components, the service life of the cutter disc is still relatively low due to various factors such as dust, and periodic knife breakage will also occur. During the production process, each shift needs to stop the machine to cut the knife once, resulting in low cigarette processing efficiency and failure to meet the existing tobacco orderly heated cigarette processing and production needs.

[0004] Therefore, how to provide a system for orderly heating cigarette filter rods and cutting cigarettes has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] An object of the present invention is to provide a new technical solution for a system for orderly heating cigarette filter rods and cutting cigarettes.

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] like Figures 1 to 4 As shown, an embodiment of the present invention provides a system for orderly heating cigarette filter rods and cigarette cutting, comprising: a cutter 1, a clamping assembly, a driving assembly and a negative pressure assembly.

[0032] The clamping assembly includes two clamping disks 2, an annular notch 21, multiple sliders 3 and a damping part 4. The annular notch 21 is arranged near the center position of the clamping disk 2. The multiple sliders 3 are respectively slidably arranged on the outer peripheral walls of the two clamping disks 2. The cutter 1 is located between the multiple clamping disks 2 and the two sliders 3. The damping part 4 is respectively connected to the slider 3 and the clamping disk 2.

[0033] Specifically, the two clamping plates 2 fix the cutter 1 so that the cutter 1 can stably cut the filter rod cigarette.

[0034] The drive assembly is connected to the center of the clamping disc 2 and is used to drive the clamping disc 2 to rotate. The drive assembly changes the rotation speed of the clamping disc 2 and cooperates with the damping part 4 to adjust the positions of the multiple sliders 3 on the outer wall of the cutter 1 to adjust the rigidity of the cutter 1.

[0035] The negative pressure component is communicated with the annular gap 21 .

[0036] Specifically, the damping part 4 can provide a limiting effect on the slider 3 to prevent the slider 3 from sliding out of the clamping plate. In addition, through the damping part 4, the resistance provided by the damping part 4, the friction between the slider 3 and the clamping plate 2, and the centrifugal force generated when the clamping plate 2 rotates can be balanced. That is, when the centrifugal force increases or decreases, the resistance provided by the damping part 4 also increases or decreases accordingly, so that the slider 3 can move on the clamping plate 2, thereby changing the stiffness of the cutter 1.

[0037] Moreover, when the slider 3 is closer to the outer edge of the cutter 1, the clamping effect and supporting effect of the slider 3 on the cutter 1 are better, and the overall rigidity of the blade is greater; when the slider 3 is closer to the inner edge of the cutter 1, the clamping effect and supporting effect of the slider 3 on the cutter 1 are weaker, and the overall rigidity of the blade is smaller.

[0038] When the rotation speed of the clamping disk 2 increases, the centrifugal force exerted on the slider 3 becomes greater. At this time, the slider 3 will move toward the outer edge of the clamping disk 2 or the cutter 1, and as the slider 3 moves toward the outer edge of the clamping disk 2 or the cutter 1, the resistance of the damping part 4 to the slider 3 gradually increases; when the centrifugal force exerted on the slider 3 is balanced by the resistance provided by the damping part 4 and the friction force between the slider 3 and the clamping disk 2, the slider 3 and the clamping disk 2 remain relatively stationary, thereby increasing the supporting effect of the slider 3 on the cutter 1, improving the overall stiffness of the blade, and thereby increasing the number of filter rods and cigarettes cut by the blade per unit time.

[0039] When the rotation speed of the clamping disk 2 decreases, the centrifugal force exerted on the slider 3 becomes smaller. At this time, the centrifugal force exerted on the current slider 3 is less than the resistance provided by the current damping part 4 and the friction between the slider 3 and the clamping disk 2, so that the slider 3 moves toward the inside of the clamping disk 2 or the cutter 1, and as the slider 3 moves toward the inside of the clamping disk 2 or the cutter 1, the resistance of the damping part 4 to the slider 3 gradually decreases; when the centrifugal force exerted on the slider 3 is balanced by the resistance provided by the damping part 4 and the friction between the slider 3 and the clamping disk 2, the slider 3 and the clamping disk 2 remain relatively stationary. At this time, the change in the position of the slider 3 reduces the supporting effect of the slider 3 on the cutter 1, reduces the overall stiffness of the blade, and thereby reduces the number of filter rods and cigarettes cut by the blade per unit time. The present invention adjusts the rotation speed of the clamping disk 2 through the driving component according to the actual cutting requirements for filter rod cigarettes, so that the balance between the centrifugal force exerted on the slider 3, the resistance provided by the damping part 4, and the friction between the slider 3 and the clamping disk 2 changes, thereby changing the position of the slider 3 on the cutter 1, and adjusting the rigidity of the cutter 1, thereby ensuring the cutting quality and the service life of the cutter disk, effectively ensuring the cutting efficiency, reducing the number of maintenance and the labor intensity of maintenance personnel, and improving production efficiency.

[0040] The present invention arranges an annular notch 21 near the center of the clamping disk 2, and slides 3 are slidably disposed on the outer peripheral walls of the two clamping disks 2. The cutter 1 is positioned between the multiple clamping disks 2 and the two slides 3. A drive assembly is connected to the center of the clamping disks 2 to drive the clamping disks 2 to rotate. The present invention uses the drive assembly to change the rotational speed of the clamping disks 2 and, in conjunction with the damping unit 4, adjusts the position of the multiple slides 3 on the outer wall of the cutter 1 to adjust the rigidity of the cutter 1. This improves the service life and production efficiency of the cutter 1, while reducing the likelihood of maintenance and the labor intensity of maintenance personnel.

[0041] In one embodiment of the orderly heated cigarette filter rod and cigarette cutting system of the present invention, the sliders 3 are respectively located on both sides of the cutter 1, and each side has four sliders 3, and the sliders 3 are arc-shaped structures.

[0042] The present invention provides four sliders 3 on both sides of the cutter 1 so that the four sliders 3 slide on the side walls of the cutter 1, thereby being able to adjust the rigidity of the cutter 1 in all directions, further improving the service life of the cutter 1 and meeting the cutting requirements.

[0043] In one embodiment of the orderly heated cigarette filter rod and cigarette cutting system of the present invention, the clamping assembly further includes four grooves, which are respectively arranged on the clamping disk 2 and are evenly spaced along the circumference of the clamping disk 2, and the slider 3 is slidably arranged in the groove.

[0044] The present invention provides four grooves on the clamping disk 2 at even intervals along the circumference of the clamping disk 2 , and slides the slider 3 in the grooves, thereby enabling the slider 3 to move stably on the clamping disk 2 .

[0045] In one embodiment of the system for orderly heating cigarette filter rods and cigarette cutting of the present invention, Figure 1 and Figure 3 As shown, the clamping assembly further includes four guide rails 22 , which are arranged in the grooves; a sliding groove 31 is provided at the bottom of the slider 3 , which is slidably connected to the guide rails 22 .

[0046] The present invention provides a slide groove 31 at the bottom of the slider 3, so that the guide rail 22 is set in the groove. The slide groove 31 is slidably connected to the guide rail 22, further increasing the stability of the slider 3 moving on the clamping plate 2, thereby increasing the stability of the orderly heated cigarette filter rod and cigarette cutting system of the present invention during operation.

[0047] Furthermore, the thickness of the slider 3 is greater than the thickness of the clamping plate 2 , and a dust channel 5 is formed between two adjacent sliders 3 , and the dust channel 5 is communicated with the annular notch 21 .

[0048] Specifically, when the sliders 3 move toward the outer edge of the clamping plate 2 or cutter 1, the gap between adjacent sliders 3 increases, thereby increasing the width of the dust passage 5. This increases the amount of dust sucked in by the negative pressure assembly and enhances its dust removal capability. When the sliders 3 move toward the interior of the clamping plate 2 or cutter 1, the gap between adjacent sliders 3 decreases, thereby decreasing the width of the dust passage 5. This decreases the amount of dust sucked in by the negative pressure assembly and weakens its dust removal capability.

[0049] It should be noted that the negative pressure component of the present invention adopts the negative pressure dust collection device of the prior art, which will not be described here.

[0050] In one embodiment of the system for orderly heating cigarette filter rods and cigarette cutting of the present invention, Figure 3 and Figure 4As shown, the clamping assembly also includes a spring 41, a limit block 42 and a limit protrusion 43. The spring 41 is sleeved on the guide rail 22, and the first end of the spring 41 is connected to the first end of the guide rail 22, the second end of the spring 41 is connected to the slider 3, the limit block 42 is arranged on the second end of the guide rail 22, the width of the limit block 42 is smaller than the width of the slide groove 31, the limit protrusion 43 is arranged in the slide groove 31, and is located on the inner side of the slider 3, and the limit protrusion 43 abuts against the limit block 42.

[0051] Specifically, when the rotation speed of the clamping disk 2 increases, the centrifugal force exerted on the slider 3 becomes greater, causing the slider 3 to move toward the outer edge of the clamping disk 2 or the cutter 1. At this time, the spring 41 will gradually increase the elastic force on the slider 3. When the elastic force generated by the spring 41, the friction force between the slider 3 and the clamping disk 2, and the centrifugal force exerted on the slider 3 are equal, the slider 3 and the clamping disk 2 remain relatively stationary.

[0052] When the rotation speed of the clamping disk 2 increases, the centrifugal force exerted on the slider 3 becomes smaller, causing the slider 3 to move toward the inside of the clamping disk 2 or the cutter 1. At this time, the centrifugal force exerted on the slider 3 is less than the elastic force generated by the spring 41 and the friction force between the slider 3 and the clamping disk 2, causing the slider 3 to move toward the inside of the clamping disk 2 or the cutter 1, and as the slider 3 moves toward the inside of the clamping disk 2 or the cutter 1, the slider 3 will further move toward the inside of the clamping disk 2 or the cutter 1; as the slider 3 gradually moves toward the inside of the clamping disk 2 or the cutter 1, the elastic deformation of the spring 41 decreases, causing the elastic force generated by the spring 41 to become smaller, and when the centrifugal force exerted on the slider 3 is balanced by the elastic force generated by the spring 41 and the friction force between the slider 3 and the clamping disk 2, the slider 3 and the clamping disk 2 remain relatively stationary again, thereby increasing the supporting effect of the slider 3 on the cutter 1, improving the overall stiffness of the blade, and thereby increasing the number of filter rod cigarettes cut by the blade per unit time.

[0053] When the slider 3 moves to the second end of the guide rail 22, the limiting protrusion 43 in the slide groove 31 abuts against the limiting block 42 at the second end of the guide rail 22, thereby providing a limiting effect on the position of the slider 3, avoiding the problem of the slider 3 sliding out of the clamping plate 2.

[0054] In one embodiment of the system for orderly heating cigarette filter rods and cigarette cutting of the present invention, Figure 2 As shown, the clamping disc 2 is provided with a first fixing hole 23 , and the cutter 1 is provided with a second fixing hole.

[0055] The orderly heated cigarette filter rod and cigarette cutting system further comprises fixing bolts, which pass through the first fixing hole 23 and the second fixing hole respectively.

[0056] The present invention provides a first fixing hole 23 on the clamping plate 2 and a second fixing hole on the cutter 1, so that the fixing bolts pass through the first fixing hole 23 and the second fixing hole respectively, thereby stably fixing the cutter 1 on the clamping plate 2, so that the clamping plate 2 can stably drive the cutter 1 to rotate.

[0057] In one embodiment of the orderly heated cigarette filter rod and cigarette cutting system of the present invention, the drive assembly includes a drive motor and a frequency converter, the output shaft of the drive motor is connected to the frequency converter, and the frequency converter is connected to the clamping disk 2.

[0058] The present invention connects the output shaft of the driving motor to the frequency converter, which is then connected to the clamping disk 2 , so that the frequency converter can adjust the output power of the driving motor, thereby adjusting the rotation speed of the clamping disk 2 .

[0059] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention.
