Abstract
Description
Technical Field
[0001] This invention belongs to the field of cigarette production technology, specifically relating to an adjustable cigarette slitting cutter and slitting device. Background Technology
[0002] In the cigarette production process, the slitting process is a crucial step, directly impacting the quality of cigarette products, production efficiency, and cost control. As the core component for achieving the slitting operation, the structural design and performance of the slitting blade play a decisive role.
[0003] Traditional cigarette slitting blade structures have gradually revealed numerous limitations when facing diverse production demands. Early slitting blades mostly employed a fixed structure, with the blade's position on the rotating shaft remaining relatively fixed. This meant that the slitting position could not be flexibly adjusted when cutting cigarette materials of different specifications. As the variety of cigarette products has increased, different brands and models of cigarettes have varying requirements for cigarette length, filter length, and packaging material slitting dimensions. Fixed-structure slitting blades have proven inadequate for these diverse slitting needs.
[0004] To accommodate variations in slitting specifications, some slitting blade structures employ complex adjustment mechanisms, such as multiple sets of bolts, nuts, and sliders, to fine-tune the blade's position. However, this adjustment method is cumbersome. In actual production, whenever a change in slitting specifications is needed, operators must spend a significant amount of time loosening, adjusting, and retightening various adjustment components. This not only reduces production efficiency but also makes it difficult to guarantee consistent adjustment accuracy due to human error. Deviations in adjustment precision can lead to non-standard slitting dimensions, resulting in a large number of defective products and increased production costs.
[0005] Furthermore, the existing slitting blade structure presents numerous inconveniences in terms of maintenance and upkeep. During prolonged high-speed operation, the blade body is prone to wear, especially when slitting materials with high hardness or special properties. When the slitting blade needs replacement, its complex design makes disassembly and installation extremely difficult, further extending equipment downtime and impacting production continuity.
[0006] Against this backdrop, it is imperative to develop a slitting blade structure that can quickly and accurately adjust the slitting position while also possessing advantages such as simple structure and easy maintenance. Utility Model Content

[0051] Example 1
[0052] refer to Figure 1 , 2This patent provides an adjustable cigarette slitting cutter 1000, comprising: a rotating shaft 100, a cutting element 200, and a preset distance adjusting element 300; the rotating shaft 100 provides rotation, and the cutting element 200 and the preset distance adjusting element 300 are detachably mounted on the rotating shaft 100; the cutting element 200 is used to cut cigarette material, and the cutting element 200 can rotate with the rotating shaft 100, and when rotating, the cutting element 200 can cut the cigarette material; the preset distance adjusting element 300 is used to adjust the axial position of the cutting element 200 on the rotating shaft 100, and the preset distance adjusting element 300 has a preset axial dimension, and when the cutting element 200 and the preset distance adjusting element 300 are axially fixed on the rotating shaft 100, the cutting element 200 abuts against the preset distance adjusting element 300.
[0053] The adjustable cigarette slitting cutter 1000 of this patent allows for quick assembly and disassembly of the cutting component 200 and the preset distance adjustment component 300, facilitating changes in size and production specifications. The preset axial dimension and preset distance adjustment component 300 enable quick determination of the cutting component's position, avoiding repeated adjustments and confirmations by operators, improving efficiency, reducing waste, and contributing to product stability.
[0054] Specifically, the cutting component 200 is implemented as a slitting blade. The preset distance adjustment component 300 is implemented as a sleeve, which can be quickly fitted onto the rotating shaft 100.
[0055] In this embodiment, the adjustable cigarette slitting cutter 1000 further includes a fixing member 400, which is used to axially fix the cutting member 200 and the preset distance adjusting member 300. When the cutting member 200 and the preset distance adjusting member 300 are axially fixed on the rotating shaft 100, the fixing member 400 abuts against the preset distance adjusting member 300. The rotating shaft 100 includes a first stepped plane, which abuts against the end face of the preset distance adjusting member 300. The cutting member 200 and the preset distance adjusting member 300 are disposed between the first stepped plane and the fixing member 400. The fixing member 400 is disposed at the end of the rotating shaft 100 and is detachably connected to the rotating shaft 100. The rotating shaft 100 includes a first threaded portion, and the fastener 500 includes a second threaded portion. The first threaded portion and the second threaded portion are threadedly engaged so that the fixing member 400 has a defined installation position on the rotating shaft 100.
[0056] Specifically, the rotating shaft 100 is a stepped shaft with a large diameter section and a small diameter section. The first stepped plane is located between the large diameter section and the small diameter section, and the small diameter section is located at the far end of the large diameter section.
[0057] In this embodiment, the cutting member 200 includes a first cutting member 210 and a second cutting member 220, and both the first cutting member 210 and the second cutting member 220 are provided with a preset distance adjusting member 300. The preset distance adjusting member 300 includes a first preset distance adjusting member and a second preset distance adjusting member, the first preset distance adjusting member having a first preset axial dimension and the second preset distance adjusting member having a second preset axial dimension. The preset distance adjusting member 300 also includes a third preset distance adjusting member, the third preset distance adjusting member having a third preset axial dimension.
[0058] In other embodiments, the third preset distance adjustment element may be configured as multiple to provide more flexible or precise distance adjustment.
[0059] Specifically, in this embodiment, the first preset axial dimension is greater than the third preset axial dimension. The first preset axial dimension, the second preset axial dimension, and the third preset axial dimension can be independently taken from 5mm to 2000mm or directly or indirectly combined to form other axial specifications commonly used in the production process of cigarette products.
[0060] Specifically, the adjustable cigarette slitting cutter 1000 includes a rotating shaft 100, a first sleeve, a first slitting blade, a second sleeve, a second slitting blade, a third sleeve, a fixing member 400, and bolts. The first sleeve is fitted onto the beginning of the small-diameter section of the rotating shaft 100. The first slitting blade is positioned adjacent to the first sleeve, fitted onto the rotating shaft and abutting against one end of the first sleeve. The second sleeve is positioned on the side of the first slitting blade furthest from the first sleeve, abutting against the first slitting blade. The second slitting blade is positioned adjacent to the second sleeve, fitted onto the rotating shaft and abutting against one end of the second sleeve. The third sleeve is positioned on the side of the second slitting blade furthest from the second sleeve, abutting against the second slitting blade. The fixing member 400 is fitted onto the end of the small-diameter section of the rotating shaft, abutting against the third sleeve. The first sleeve, first slitting blade, second sleeve, second slitting blade, third sleeve, and fixing member 400 are sequentially fitted onto the small-diameter section of the rotating shaft.
[0061] Fastener 500 is implemented as a bolt. The nut of the bolt presses onto the fixing part 400. The bolt shank passes through the fixing part 400 and is threadedly connected to the threaded hole at the end of the small diameter section of the rotating shaft. By tightening the bolt, the first sleeve, the first slitting blade, the second sleeve, the second slitting blade, the third sleeve and the fixing part 400 are fixed on the rotating shaft, so that the components are tightly connected and form a whole.
[0062] Specifically, the first cutting element 210 is configured as the first slitting blade, and the second cutting element 220 is configured as the second slitting blade. During use, when it is necessary to adjust the position of the first and second slitting blades relative to the drum to achieve different slitting lengths, simply loosen the bolts, remove the fixing element 400, and then replace the first, second, and third sleeves with different lengths according to the required cutting distance. Since the first sleeve is located between the first slitting blade and the large-diameter section of the rotating shaft, changes in its length will alter the axial position of the first slitting blade on the rotating shaft; the second sleeve is located between the first and second slitting blades, and changes in its length will alter the distance between the first and second slitting blades; the third sleeve is located between the second slitting blade and the fixing element 400, and changes in its length will affect the axial position of the second slitting blade. By changing different combinations of the lengths of these three sleeves, the position of the first and second slitting blades relative to the drum can be precisely adjusted, thereby achieving slitting lengths.
[0063] When this device is installed on the slitting equipment, the first and second slitting blades are in standby mode. When the production task requires shorter slitting of the material, first loosen the bolts with a wrench. After the bolts are completely loosened, remove the fixing part 400 from the end of the small-diameter section of the rotating shaft. At this time, remove the third sleeve, the second slitting blade, the second sleeve, the first slitting blade, and the first sleeve in sequence. According to the requirement of shorter slitting length, select the shorter first sleeve, the second sleeve, and the third sleeve. Place the new first sleeve on the beginning of the small-diameter section of the rotating shaft, so that one end abuts against the large-diameter section; then place the first slitting blade on the small-diameter section, so that it abuts against the other end of the first sleeve; then place the new second sleeve, the second slitting blade, and the new third sleeve in sequence, so that the second sleeve abuts against the first slitting blade, the second slitting blade abuts against the second sleeve, and the third sleeve abuts against the second slitting blade; finally, place the fixing part 400 on the end of the small-diameter section, abutting against the third sleeve. Tighten the bolts again with a wrench until the nut presses onto the fixing part 400, firmly securing all components to the rotating shaft. At this point, the positions of the first and second slitting blades relative to the drum change, enabling slitting operations with shorter lengths.
[0064] When production tasks change and require longer material slitting, repeat the above steps of loosening bolts and removing fastener 400 and other components. Based on the required longer slitting length, select longer first, second, and third sleeves. Following the same installation sequence, install the new sleeves and slitting blades onto the rotating shaft, then install fastener 400 and tighten the bolts. By replacing the sleeves with longer ones, the axial positions of the first and second slitting blades on the rotating shaft change, and the distance between them increases accordingly, thus achieving longer slitting.
[0065] Furthermore, in some special slitting requirements, such as adjusting the relative positional relationship between the first and second slitting blades to meet the slitting requirements of materials with special shapes, the bolts are first loosened and the fixing parts 400 and other components are removed. By selecting different combinations of the lengths of the first, second, and third sleeves, such as increasing the length of the first sleeve or decreasing the length of the second sleeve, the positions of the first and second slitting blades on the rotating shaft are changed. After reinstalling and fixing them, the two slitting blades can slit the materials with special shapes at appropriate intervals and positions, effectively meeting diverse production slitting needs.
[0066] Example 2
[0067] refer to Figure 3 Embodiment 2 provides an adjustable cigarette slitting cutter that is essentially the same as that in Embodiment 1, except that the rotating shaft 100 further includes a second stepped plane 110, which abuts against the end face of the fixing member 400. The cutting member 200 and the preset distance adjustment member 300 are disposed between the first stepped plane and the second stepped plane 110. Advantageously, the second stepped plane 110 facilitates the fixing member 400 to have a preset axial position, resulting in higher precision when the fixing member 400 abuts against the preset distance adjustment member 300.
