[0002] In the tobacco product manufacturing process, the cutting drum is a core component of the tobacco processing equipment, used for separating and cutting cigarette components such as filter rods or cigarette sticks. Its operational stability directly affects production efficiency and product quality. In actual cutting, such as... Figure 1 and Figure 2 As shown, it is also necessary to use the rejection roller 100' and the guard plate 200' to remove defective cigarette components. Specifically, the cigarette components in the storage bin pass through the gap between the rejection roller 100' and the cutting drum 10' in sequence to remove defective cigarette components. However, when the storage bin contains bent or deformed filter rods (especially hollow filter rods, which are prone to bending and deformation) or cigarette components, two cigarette components may simultaneously enter the gap and then the cutting drum 10', causing blockage. Frequent blockage can easily damage parts such as the chain lugs in the tobacco processing device, increasing replacement costs.
[0003] Therefore, there is an urgent need to develop a tobacco cutting anti-clogging device to solve the above problems. Utility Model Content

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0034] This embodiment provides a tobacco cutting anti-clogging device that can restrict the entry path of tobacco components, prevent two tobacco components from entering the cutting drum at the same time, thereby avoiding clogging of the cutting drum and reducing costs.
[0035] Specifically, such as Figure 3 and Figure 4As shown, the tobacco cutting anti-clogging device includes a rejection roller assembly 100 and a guard plate assembly 200. The rejection roller assembly 100 includes a shaft 110 and a plurality of rejection rollers 120. Exemplarily, the number of rejection rollers 120 can be two, three, four, five, or seven, etc. The shaft 110 and the central axis of the cutting drum 10 are parallel. The plurality of rejection rollers 120 are sleeved on the shaft 110 and spaced apart along the axial direction of the shaft 110. A gap is left between the shaft 110 and the cutting drum 10. The size of the gap is larger than the size of the tobacco piece. Specifically, the single-sided distance of the gap after accommodating a single tobacco piece (the tobacco piece is parallel to the shaft 110) is 0.2mm-0.4mm, and the gap is divided into multiple segments along the axial direction of the shaft 110. The guard plate assembly 200 includes a guard tooth 210, which is located on the side of the rejection roller assembly 100 facing the material storage and between two adjacent rejection rollers 120. The guard tooth 210 includes a straight segment 211 and an arc segment 212. The straight segment 211 extends in the direction toward the cutting drum 10, and one end of the arc segment 212 is connected to the straight segment 211, while the other end extends along the outer circumference of the shaft 110 and wraps around the shaft 110.
[0036] Based on the above design, multiple rejection rollers 120 are spaced apart along the axial direction of the shaft 110, working together with the guard plate assembly 200 to reject defective cigarette components. A gap is left between the shaft 110 and the cutting drum 10, the size of which is larger than the size of the cigarette component, allowing a single cigarette component to pass through. The guard plate assembly 200 includes guard teeth 210, which includes a straight segment 211 and an arc segment 212. The straight segment 211 extends towards the cutting drum 10, and one end of the arc segment 212 is connected to the straight segment 211, while the other end extends along the outer circumference of the shaft 110 and wraps around the shaft 110. Compared with the prior art, extending the length of the guard teeth 210 to the gap reduces the width of the gap, restricts the entry path of the cigarette components, prevents two cigarette components from entering the cutting drum 10 at the same time, thereby avoiding blockage of the cutting drum 10 and reducing costs.
[0037] Typically, the cigarette fitting is a round rod with a diameter of 5.20 mm and a circumference of 16.35 mm.
[0038] Optionally, the guard plate assembly 200 also includes a plate body 220, with guard teeth 210 located on the side of the plate body 220 facing the cutting drum 10, and guard teeth 210 fixed.
[0039] In this embodiment, the plate 220 and the tooth guard 210 are integrally formed, which simplifies the processing.
[0040] Optionally, the axial dimension of the shaft 110 is 120mm, and the axial dimension of each rejection roller 120 is 18mm-20mm. With the axial dimension of the shaft 110 determined, increasing the axial dimension of each rejection roller 120 and reducing the spacing between rejection rollers 120 can reduce the length of each segment of the gap (along the length direction of the shaft 110) and reduce the possibility of cigarette residue.
[0041] For example, the axial dimension of each rejection roller 120 can be 18mm, 19mm or 20mm, etc.
[0042] Optionally, the number of rejection rollers 120 ranges from two to five, which reduces the number of rejection rollers 120 compared to the prior art, simplifies the structure and reduces maintenance complexity.
[0043] In this embodiment, the number of rejection rollers 120 is four.
[0044] Optionally, the straight segment 211 of the tooth protector 210 is tangent to the shaft 110, and the transition portion between the straight segment 211 and the arc segment 212 fits the shaft 110, resulting in a compact structure.
[0045] Furthermore, the ratio of the arc length of the arc segment 212 to the circumference of the shaft 110 is in the range of 1 / 5 to 1 / 3. If the arc length of the arc segment 212 is too short, it is insufficient to block the gap and cannot restrict the entry path of the two cigarette components. If the arc length of the arc segment 212 is too long, it extends beyond the gap range, and the part that exceeds the gap does not restrict the entry path of the two cigarette components, resulting in unnecessary waste.
[0046] For example, the ratio of the arc length of the arc segment 212 to the circumference of the shaft 110 can be 1 / 5, 1 / 4, or 1 / 3, etc.
[0047] In this embodiment, the arc length of the arc segment 212 is 1 / 4 of the circumference of the shaft 110, which can not only restrict the entry path of the two cigarette pieces, but also save materials and simplify the processing.
[0048] Optionally, there are multiple guard teeth 210, with guard teeth 210 provided between each pair of adjacent rejection rollers 120. The multiple guard teeth 210 are distributed along the length of the cigarette component, and together restrict the entry path of the two cigarette components from different positions.
[0049] Here, there are at least three removal rollers 120. For example, the number of guard teeth 210 can be two, three, four, or six, etc.
[0050] Optionally, there are multiple guard teeth 210, with guard teeth 210 provided at both ends of each rejection roller 120 along the axial direction of the shaft 110. That is, in addition to guard teeth 210 being provided between adjacent rejection rollers 120, guard teeth 210 are also provided at the outer ends of the two outermost rejection rollers 120, thus restricting the entry path of the two cigarette pieces along the entire length of the cigarette piece.
[0051] For example, the number of the aforementioned tooth protectors 210 is three, four, or six, etc.
[0052] This embodiment also provides a tobacco processing apparatus that has a long service life and low cost.
[0053] Specifically, the tobacco processing apparatus includes a cutting drum 10, a feed hopper, and the aforementioned tobacco cutting anti-clogging device. The tobacco components in the feed hopper are conveyed to the cutting drum 10 for cutting, and the rejecting roller assembly 100 removes defective tobacco components from the conveyed feed hopper. The guard plate assembly 200 includes guard teeth 210, located on the side of the rejecting roller assembly 100 facing the feed hopper and between two adjacent rejecting rollers 120. The guard teeth 210 include a straight segment 211 and an arc segment 212. The straight segment 211 extends towards the cutting drum 10, and one end of the arc segment 212 connects to the straight segment 211, while the other end extends circumferentially along the shaft 110 and wraps around it. Compared to existing technologies, extending the length of the guard teeth 210 to the gap reduces the gap size, thereby restricting the entry path of the tobacco components, preventing two tobacco components from entering the cutting drum 10 simultaneously, thus preventing blockage of the cutting drum 10, extending the service life of the tobacco processing apparatus, and reducing costs.
[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
