Description

Technical Field

[0001] This utility model relates to the field of cutting devices, and in particular to a filter rod cutting device. Background Technology

[0002] Filter rods in cigarette products are mainly used to filter impurities and particulate matter in cigarette smoke, and their forming and cutting precision directly affects the quality of the final cigarette product. Existing filter rod cutting methods typically involve manual operation using blades or similar tools. This type of cutting method is prone to displacement or rotation of the filter rod during cutting, resulting in defects such as burrs, wrinkles, and uneven gaps on the cut end face. Furthermore, human error can easily lead to sample length deviations, resulting in operational instability and poor repeatability. This affects the dimensional consistency of the cut samples and may interfere with subsequent physical performance tests, especially when obtaining structurally intact and dimensionally consistent samples or conducting performance tests, making it difficult to meet high-precision requirements. Utility Model Content

[0003] The purpose of this invention is to solve the technical problems of burrs, wrinkles, uneven gaps, and large errors in cutting length that exist in the existing filter rod cutting process. This invention provides a filter rod cutting device that can stably limit and accurately position the filter rod and achieve fixed-length cutting, ensuring that the end face of the cut filter rod is neat and consistent.

[0004] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a filter rod cutting device, comprising:

[0005] The base has a positioning groove and a measuring scale extending along a first direction on its upper surface. The positioning groove is used to accommodate the filter rod.

[0006] A support is provided on the base. The bottom of the support is provided with a limiting groove that extends through the support in a first direction. The limiting groove corresponds to the positioning groove. The filter rod can pass through the limiting groove. The limiting groove is used to limit the position of the filter rod.

[0007] The cutting blade is rotatably mounted on the support. The bottom of the cutting blade is equipped with a cutting edge, the extension direction of which is perpendicular to the first direction. The cutting edge is aligned with the zero point of the measuring scale. The cutting blade is used to cut the filter rod in the positioning groove.

[0008] A limiting plate is provided on the base. The limiting plate and the support are spaced apart along the first direction. The limiting plate extends along the second direction, which is perpendicular to the first direction and parallel to the upper surface of the base. The limiting plate can slide relative to the base along the first direction.

[0009] In use, the operator first places the device flat on the operating table and slides the limiting plate along the first direction until the side wall of the limiting plate facing the support is aligned with the preset scale. Then, the filter rod is placed into the positioning groove and pushed along the first direction, allowing it to pass through the positioning groove and the limiting groove until the end of the filter rod abuts against the limiting plate. At this point, the circumferential surface of the filter rod is in contact with the inner walls of both the positioning groove and the limiting groove. Next, the cutting blade is rotated to cut the filter rod. The filter rod remaining between the cutting blade and the limiting plate is the required length.

[0010] By adopting the above technical solution, and by setting a limiting plate and a measuring ruler, the operator can easily limit the axial movement of the filter rod and intuitively read the limiting dimensions of the filter rod, thereby ensuring the accuracy of the length of the filter rod sample. Furthermore, by setting positioning grooves and limiting grooves, it is possible to prevent the filter rod from shaking, tilting, or warping during the cutting process, avoiding burrs, wrinkles, or uneven gaps on the end face of the filter rod, thus effectively ensuring the neatness and consistency of the filter rod end face.

[0011] Optionally, the support has a cavity extending through the support along a third direction, which is perpendicular to the upper surface of the base. A positioning groove passes through the bottom of the cavity, and the cutting blade is at least partially located inside the cavity.

[0012] Optionally, the top of the cutter is provided with a handle, which is located outside the cavity.

[0013] Optionally, there may be multiple positioning slots, with each positioning slot spaced apart sequentially along the second direction.

[0014] Optionally, the inner walls of both the positioning groove and the limiting groove are arc-shaped, and the positioning groove and its corresponding limiting groove enclose a circular through hole, the diameter of which is equal to the diameter of the filter rod inserted into it.

[0015] Optionally, at least two positioning slots may have different diameters to accommodate filter rods of different sizes.

[0016] Optionally, the upper surface of the base is provided with two limiting protrusions spaced apart along the second direction. Both limiting protrusions extend along the first direction. The support, the cutting blade, and the limiting plate are all located between the two limiting protrusions. The two ends of the limiting plate along the second direction are in contact with the two limiting protrusions respectively.

[0017] Optionally, each of the two limiting protrusions has a groove extending in the first direction on its inner wall, and each of the two ends of the limiting plate in the second direction has a slider, which is inserted into the two grooves respectively.

[0018] Optionally, the base is made of metal, and the bottom of the limiting plate is equipped with a magnet, which allows the limiting plate to be attracted to the base.

[0019] Optionally, the surface of the limiting plate facing the support is perpendicular to the first direction, and a protrusion is provided on the surface of the limiting plate facing away from the support. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] To address the problems of burrs, wrinkles, uneven gaps, and large errors in cutting length during the existing filter rod cutting process, this utility model discloses a filter rod cutting device. This device achieves stable limiting, precise positioning, and fixed-length cutting of the filter rod, ensuring that the cut filter rod end faces are neat and consistent, thereby effectively improving the work efficiency of users and the accuracy of filter rod sample dimensions.

[0030] like Figure 1 and Figure 2 As shown, the filter rod cutting device provided in this embodiment includes a base 1, a support 4, a cutting blade 6, and a limiting plate 8. The upper surface of the base 1 is provided with a first direction (e.g., Figure 1 and Figure 2 The positioning groove 2 (shown in the X direction) extends into a measuring scale 3. The positioning groove 2 is used to accommodate the filter rod. The measuring scale 3 is engraved with length graduations along the first direction for measuring the length of the filter rod within the positioning groove 2. Exemplarily, the length graduation range is 0–120 mm.

[0031] The support 4 is fixedly mounted on the base 1. The bottom of the support 4 has a limiting groove 5 extending through the support 4 in a first direction. The limiting groove 5 corresponds to the position of the positioning groove 2, allowing the filter rod to pass through it. The limiting groove 5 is used to limit the position of the filter rod. For example, the inner walls of both the positioning groove 2 and the limiting groove 5 are designed as arc-shaped curved surfaces, forming a circular through hole 11. The diameter of the through hole 11 matches the diameter of the filter rod. When the filter rod is inserted into the through hole 11, the circumferential surface of the filter rod fits against the inner walls of the positioning groove 2 and the limiting groove 5, respectively. This prevents the filter rod from shaking, tilting, or warping within the positioning groove 2, improving the positional stability of the filter rod during the cutting process. Furthermore, it prevents burrs, wrinkles, or uneven gaps on the end face of the filter rod, effectively ensuring the quality of the filter rod's end face.

[0032] The cutting blade 6 is rotatably mounted on the support 4. The bottom of the cutting blade 6 has a cutting edge 7, the extension direction of which is perpendicular to a first direction. The cutting edge 7 is aligned with the zero point of the measuring scale 3. The cutting blade 6 is used to cut the filter rod within the positioning groove 2. Exemplarily, the cutting blade 6 is rotatably connected to the support 4 via a hinge. Exemplarily, the cutting edge 7 is made of carbon steel, sharp and durable, suitable for cutting standard cigarette filter rods.

[0033] The limiting plate 8 is disposed on the base 1, and the limiting plate 8 and the support 4 are spaced apart along the first direction. The limiting plate 8 is also disposed along the second direction (e.g., Figure 1 and Figure 2 The first direction extends along the Y direction (as shown), and the second direction is perpendicular to the first direction and parallel to the upper surface of the base 1. The limiting plate 8 can slide relative to the base 1 within the length scale of the measuring ruler 3 along the first direction.

[0034] In use, the operator first places the device flat on the operating table and slides the limiting plate 8 along the first direction until the side wall of the limiting plate 8 facing the support 4 is aligned with the preset scale. Then, the filter rod is placed into the positioning groove 2 and pushed along the first direction until it passes through the through hole 11 formed by the positioning groove 2 and the limiting groove 5, until the end of the filter rod abuts against the limiting plate 8. Then, the cutting blade 6 is rotated to cut the filter rod. The filter rod remaining between the cutting blade 6 and the limiting plate 8 is the required fixed-length filter rod.

[0035] By adopting the above technical solution, the limiting plate 8 and measuring ruler 3 facilitate the operator to axially limit the filter rod and intuitively read the limiting dimension of the filter rod, thereby ensuring the accuracy of the length dimension of the filter rod sample. In addition, by setting the positioning groove 2 and limiting groove 5, it is possible to prevent the filter rod from shaking, tilting and warping during the cutting process, and avoid burrs, wrinkles or uneven gaps on the end face of the filter rod, thereby effectively ensuring the neatness and consistency of the filter rod end face.

[0036] This application does not limit the connection method between the support 4 and the base 1. For example, the support 4 can be fixedly installed on the base 1 by screws, or it can be connected to the base 1 by a snap-fit ​​or magnetic component. Any technical solution that can ensure that the support 4 is mounted on the base 1 and will not shift during use is within the protection scope of this application.

[0037] In some embodiments of this application, the support 4 is provided along a third direction (e.g., Figure 1The cavity 9 of the support 4 is penetrated in the Z direction (as shown), and the third direction is perpendicular to the upper surface of the base 1. The positioning groove 2 passes through the bottom of the cavity 9, and both the positioning groove 2 and the limiting groove 5 are connected to the cavity 9. The cutting blade 6 is at least partially located inside the cavity 9. Specifically, when the cutting blade 6 cuts the filter rod downwards, the cutting edge 7 of the cutting blade 6 is completely located inside the cavity 9, thereby preventing the operator from coming into contact with the cutting edge 7 and being injured, reducing accidental contact and safety risks. In addition, the inner wall of the cavity 9 can also block the flying debris generated when cutting the filter rod, preventing the flying debris from affecting the operator's vision.

[0038] Furthermore, to facilitate the operator's application of force, a handle 10 is provided on the top of the cutting blade 6, located in the outer area of ​​the cavity 9. When the operator performs a cutting operation, the cutting blade 6 can be rotated by the handle 10, thereby driving the blade 7 to cut the filter rod. This structure improves user comfort.

[0039] In some embodiments of this application, the device is provided with multiple positioning slots 2 arranged side by side, with each positioning slot 2 spaced apart along a second direction. This allows multiple filter rods to be placed and positioned and cut separately in the same operation, improving operational efficiency and making it suitable for batch sample preparation scenarios.

[0040] Furthermore, to accommodate filter rods of different diameters, each positioning groove 2 can be set with a different diameter to accommodate filter rods of different specifications. The operator can select the corresponding positioning groove 2 according to the diameter of the required sample, thereby ensuring that the filter rod can be stably positioned after insertion. For example, five positioning grooves 2 can be set, with diameters of 3.8mm, 3.9mm, 4.0mm, 4.1mm and 4.2mm respectively.

[0041] In some embodiments of this application, the upper surface of the base 1 is provided with two limiting protrusions 12 spaced apart along a second direction. Both limiting protrusions 12 extend along a first direction. The support 4, the cutting blade 6, and the limiting plate 8 are all disposed between the two limiting protrusions 12. The two ends of the limiting plate 8 along the second direction respectively contact the two limiting protrusions 12. By providing the limiting protrusions 12, the limiting plate 8 can be constrained along the second direction during sliding adjustment, which helps to make the limiting plate 8 slide smoothly and avoid lateral displacement.

[0042] Furthermore, the inner walls 13 of the two limiting protrusions are respectively provided with sliding grooves 14 extending in the first direction. A slider 15 is provided on each side of the limiting plate 8. The two sliders 15 are respectively inserted into the two sliding grooves 14 and can slide within the sliding grooves 14. By setting the sliders 15 and the sliding grooves 14, the limiting plate 8 can slide smoothly in the first direction without shaking, and the adjusted position is easy to maintain.

[0043] In some embodiments of this application, the base 1 is made of metal, and the bottom of the limiting plate 8 is provided with a magnet that can attract the base 1. After the position of the limiting plate 8 is adjusted, the position of the limiting plate 8 can be fixed by the attraction of the magnet to the base 1, thereby preventing the limiting plate 8 from moving.

[0044] In some embodiments of this application, the surface of the limiting plate 8 facing the support 4 is perpendicular to the first direction. When the filter rod abuts against the limiting plate 8, the end face of the filter rod can fit against the side wall of the limiting plate 8, thereby improving the stability of the limiting position.

[0045] In some embodiments of this application, the limiting plate 8 is provided with a protrusion 16 on the side facing away from the support 4, which facilitates the operator to apply force to push during sliding adjustment, and can also serve as a hand gripping part, improving the ease of operation.

[0046] The filter rod cutting device provided in this application can quickly cut the filter rod and ensure that the cut filter rod end face is neat and consistent, and the length of the obtained filter rod sample is accurate.

[0047] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
