Moisture testing of filter rods requires cutting them into multiple 10mm segments, which are then baked in an oven. Current technology involves manual cutting of filter rod segments, resulting in significant length errors. The varying lengths of these segments lead to different heating conditions, causing substantial fluctuations in moisture test results. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem of large errors in manually cutting filter rod segments. This invention provides a filter rod cutting device that can reduce the length error of filter rod segments.

[0004] To solve the above-mentioned technical problems, embodiments of this utility model provide a filter rod cutting device for cutting filter rods into filter rod segments, comprising:

[0005] The filter rod disc has multiple receiving holes inside to accommodate the filter rods.

[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] The present invention provides a device, such as... Figure 1 As shown, a device for cutting filter rod 1 into multiple filter rod segments 2 includes a filter rod disc 1, a limiting plate 5, and a cutter 6. The filter rod disc 1 has multiple receiving holes 4 for accommodating filter rods 3. The axis of the filter rod disc 1 is perpendicular to the horizontal plane, and the receiving holes 4 penetrate both end faces of the filter rod disc 1 vertically. The filter rod disc 1 can rotate around its own axis under external force. The limiting plate 5 is located below the filter rod disc 1, parallel to the lower end face of the filter rod disc 1. The upper surface of the limiting plate 5 is spaced a certain distance from the lower end face of the filter rod disc 1. The limiting plate 5 provides support for the filter rods 3 in each receiving hole 4. The cutter 6 extends at least partially between the limiting plate 5 and the filter rod plate 1. The lower opening of each receiving hole 4 can pass through the cutter 6 in sequence during the rotation of the filter rod plate 1. The cutter 6 is used to cut the filter rod 3 exposed below the receiving hole 4. The distance between the blade of the cutter 6 and the upper surface of the limiting plate 5 is equal to the preset length of the filter rod segment 2.

[0030] Using the above technical solution, filter rods 3 are accommodated through receiving holes 4 on the filter rod disk 1, and a limiting plate 5 is set below the filter rod disk 1. Under the action of gravity, the lower end face of the filter rod 3 in the receiving hole 4 can contact the limiting plate 5, so that the limiting plate 5 can limit the position of the lower end face of the filter rod 3. By setting a cutter 6 between the filter rod disk 1 and the limiting plate 5, and making the filter rod disk 1 rotate around its own axis, each filter rod 3 can pass through the cutter 6 in sequence as it rotates with the filter rod disk 1. When the filter rod 3 passes through the cutter 6, the cutter 6 will cut off the filter rod 3 exposed below the receiving hole 4, forming a filter rod segment 2. The distance between the blade of the cutter 6 and the upper surface of the limiting plate 5 limits the length of the filter rod segment 2 to a preset length. Figure 1 As shown by the mid-distance d), the length of each filter rod segment 2 is made consistent, thereby reducing the length error of the filter rod segment 2. Under the action of gravity, the filter rod 3, after being cut within the receiving hole 4, will continue to move downwards. As the filter rod disk 1 rotates, when the filter rod 3 passes the cutter 6 again, the cutter 6 will cut the portion of the filter rod 3 exposed below the receiving hole 4 into filter rod segments 2. In addition, in this application, the length of the filter rod 3 is an integer multiple of the length of the filter rod segment 2, and the remaining portion after multiple cuts is also a filter rod segment 2 of the preset length.

[0031] Furthermore, such as Figure 2As shown, the cutter 6 is circular and can rotate around its own axis; the cutting device also includes a drive motor 7, and the cutter 6 is connected to the output end of the drive motor 7, which drives the cutter 6 to rotate. Driving the cutter 6 to rotate at high speed via the drive motor 7 improves the cutting efficiency and quality of the filter rod 3, resulting in a neat cut surface for the filter rod segment 2.

[0032] Furthermore, such as Figure 1 As shown, the receiving holes 4 are located near the outer circumferential surface of the filter rod disk 1, and each receiving hole 4 is evenly distributed along the circumference of the filter rod disk 1. By placing the receiving holes 4 near the outer circumferential surface of the filter rod disk 1, the filter rod 3 in the receiving holes 4 can be closer to the cutter 6, thereby reducing the length of the cutter 6 extending under the filter rod disk 1 and reducing the risk of interference between the cutter 6 and the filter rod disk 1.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, the slitting device also includes a frame 8, on which a rotating shaft 9 extending vertically is provided, and the rotating shaft 9 can rotate around its own axis; the filter rod disk 1 is provided with a shaft hole 10, the axis of the shaft hole 10 coincides with the axis of the filter rod disk 1, the shaft hole 10 is sleeved on the rotating shaft 9, and can rotate with the rotating shaft 9. Specifically, as Figure 1 As shown, both the rotating shaft 9 and the shaft hole 10 are provided with keyways. The rotating shaft 9 and the shaft hole 10 are restricted to rotating in the same direction by a flat key, so that the filter rod disk 1 can rotate together with the rotating shaft 9.

[0034] Furthermore, such as Figure 1 As shown, the limiting plate 5 is sleeved on the rotating shaft 9 and can rotate with the rotating shaft 9. Specifically, the rotating shaft 9 includes a stop part, a connecting part, and a sleeve part arranged sequentially from top to bottom. The horizontal cross-sectional area of ​​the stop part is larger than the horizontal cross-sectional areas of the connecting part and the sleeve part. The lower surface of the limiting plate 5 is in contact with the upper surface of the stop part. The shaft hole 10 is sleeved on the sleeve part. The horizontal cross-section of the connecting part is square, and the center of the limiting plate 5 is provided with a square hole, which is sleeved on the connecting part. This restricts the relative rotation of the limiting plate 5 and the connecting part, allowing the limiting plate 5 to rotate with the rotating shaft 9. A spacer sleeve 11 is provided between the filter rod disc 1 and the limiting plate 5, and the spacer sleeve 11 is sleeved on the sleeve part of the rotating shaft 9. The spacer sleeve 11 is used to define the distance between the filter rod disc 1 and the limiting plate 5.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the frame 8 is provided with a collection port 12, which is located below the position where the cutter 6 contacts the filter rod 3. A collection box 13 is provided below the collection port 12. The filter rod segments 2 cut by the cutter 6 can fall into the collection port 12, making it easy to collect the filter rod segments 2.

[0036] Furthermore, such as Figure 1 and Figure 2As shown, a blocking rod 14 is provided on the downstream side of the collection port 12 along the rotation direction of the filter rod disc 1. An extension arm 15 is provided at the upper end of the blocking rod 14. The extension arm 15 extends between the filter rod disc 1 and the limiting plate 5. The extension arm 15 is used to prevent the cut-off filter rod segment 2 from moving together with the limiting plate 5, so that the filter rod segment 2 falls into the collection port 12.

[0037] Furthermore, such as Figure 1 and 2 As shown, the extension arm 15 is provided with a guide surface 16. When the filter rod section 2 contacts the guide surface 16 ( Figure 2 As shown), the guide surface 16 forms an acute angle with the forward direction of the filter rod section 2. Figure 2 As shown in angle α), the guide surface 16 is used to guide the filter rod segment 2 to move beyond the limiting plate 5. Specifically, as shown in angle α... Figure 2 As shown, the direction of movement of filter rod segment 2 when it comes into contact with guide surface 16 is the X direction, and the angle between the X direction and guide surface 16 is α. After filter rod segment 2 comes into contact with guide surface 16, it moves along the extension direction of guide surface 16 under the action of friction of limit plate 5 until it moves outside limit plate 5 and falls into collection port 12.

[0038] Furthermore, the diameter of the receiving hole 4 is larger than the diameter of the filter rod 3, and the difference between their diameters is much smaller than the diameter of the filter rod 3. This allows the filter rod 3 to not only move smoothly downwards along the receiving hole 4, but also prevents the filter rod 3 from tilting. Additionally, as... Figure 1 As shown, the upper end of the receiving hole 4 is provided with a guide section, the diameter of which gradually decreases from top to bottom. When the filter rod 3 is inserted into the receiving hole 4, the guide section can guide the filter rod 3 into the receiving hole 4.

[0039] Furthermore, a handle 17 is provided on the outer circumference of the filter rod disc 1, and the handle 17 extends vertically. This facilitates the operator to hold the handle 17 and rotate the filter rod disc 1.

[0040] 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.
