Description

Technical Field

[0001] This utility model relates to the field of cigarette manufacturing technology, and in particular to a roller assembly. Background Technology

[0002] During cigarette processing, tobacco stems in cigarette raw materials need to be processed using a tobacco stem crusher. This process mainly involves breaking down the tobacco stems so that they can be reused as filler. By reducing the waste of tobacco stems, production costs can be further reduced.

[0003] In the current technology, the process of crushing tobacco stems involves the use of a crushing roller and a frame to break the stems. The crushing roller is equipped with a crushing blade, which rotates at high speed. One side of the crushing blade has serrations to facilitate the crushing of the tobacco stems. However, during the processing, the crushing blade is prone to wear and requires frequent replacement, increasing processing costs. In addition, during rotation, the crushing blade collides with the tobacco stem and deforms. Since the crushing blade is a solid structure, it generates significant stress during processing, making it prone to breakage. Utility Model Content

[0004] The purpose of this invention is to provide a roller assembly that solves the problem of easy breakage of the beater blade in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a beating roller assembly, including a beating roller main shaft, beating blades and a through rod. A partition is arranged circumferentially on the beating roller main shaft along the axis of the beating roller main shaft. The through rod is fixed on the partition and a beating blade is sleeved on the through rod. At least one set of beating blades is installed between adjacent partitions. A weight reduction hole is provided on the beating blade. Through holes are provided on both sides of the weight reduction hole, and the through rod passes through the through holes.

[0006] Preferably, nine sets of partitions are installed at equal intervals on the main shaft of the beating roller, and beating blades are installed between the partitions.

[0007] Preferably, the rod is also provided with a spacer sleeve, three sets of cutting blades are installed between adjacent spacers, the spacer sleeve is clamped between adjacent cutting blades, and the spacer sleeve is clamped between the cutting blades and the spacers.

[0008] Preferably, the ends of the two parallel sides of the cutting blade are provided with serrations.

[0009] Preferably, a nut is screwed onto the end of the through rod, and the nut abuts against the spacer.

[0010] Preferably, the through rod has a first through hole, the nut has a second through hole, and the fixing pin passes through the first through hole and the second through hole.

[0011] Preferably, the partition plate has 9 sets of perforations at equal intervals, and the roller assembly has 9 sets of through rods installed circumferentially.

[0012] Preferably, the material of the cutting tool is 65Mn, and the weight-reducing holes on the cutting tool are elongated.

[0013] Beneficial effects: By creating weight-reducing holes in the main body of the cleaver, the inside of the cleaver becomes hollow. When the cleaver deforms during the process of chopping tobacco stems, the hollow area of ​​the weight-reducing holes can absorb the deformation of the cleaver body, reducing the problem of stress deformation of the cleaver body and reducing the risk of cleaver breakage.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0020] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. 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.

[0023] In the existing technology, the cutting tool is installed on the main shaft of the beating roller. The main shaft rotates at high speed, which drives the cutting tool to rotate at high speed, so that the cutting tool can process the broken tobacco stems. However, during the rapid rotation of the cutting tool, the cutting tool will deform during the processing of the tobacco stems, and stress will be generated on the cutting tool, which will increase the risk of the cutting tool breaking.

[0024] To solve the above problems, such as Figures 1 to 4 As shown, this utility model provides a beating roller assembly, including a beating roller main shaft 1, beating blades 2, and a through rod 3. A partition 4 is arranged circumferentially on the beating roller main shaft 1 along the axis of the beating roller main shaft 1. The through rod 3 is fixed on the partition 4. A beating blade 2 is sleeved on the through rod 3. At least one set of beating blades 2 is installed between adjacent partitions 4. A weight reduction hole 21 is provided on the beating blade 2. Through holes 22 are provided on both sides of the weight reduction hole 21. The through rod 3 passes through the through holes 22.

[0025] By creating weight-reducing holes 21 on the cutting tool 2, the cutting tool 2 will deform during operation. Since the weight-reducing holes 21 are created on the surface of the cutting tool 2, they can absorb the deformation and reduce the stress area on the cutting tool 2 where large deformation occurs. The cutting tool 2 body is bent and deformed on the side with the weight-reducing holes 21 first, which can release stress and reduce the probability of breakage. While reducing the weight of the cutting tool 2, the reliability and durability of the cutting tool 2 can be improved.

[0026] The cutting blade 2 of this invention is mounted on the through rod 3. Nine sets of partitions 4 are installed at equal intervals on the main shaft 1 of the beating roller. The through rod 3 is mounted inside the nine sets of partitions 4. By fixing the partitions 4, the through rod 3 can be installed on the periphery of the main shaft 1 of the beating roller to prevent it from falling off. At the same time, the nine sets of partitions 4 can support the through rod 3 simultaneously, which can prevent excessive stress on the through rod 3, extend the service life of the through rod 3, and prevent deformation.

[0027] The through rod 3 of this utility model is also equipped with a spacer sleeve. Three sets of striking blades 2 are installed between adjacent spacers 4, and spacers are clamped between adjacent striking blades 2 and between striking blades 2 and spacers 4. The spacers are made of rubber and fill the gaps between striking blades 2 to prevent rigid collisions between the metal striking blades 2 and between striking blades 2 and spacers 4. At the same time, the spacers fill the gaps between striking blades 2 and between striking blades 2 and spacers 4 to ensure that the striking blades 2 can be stably fixed and prevent them from rotating around the through rod 3.

[0028] The cutting blade 2 of this invention has serrations 23 on its two parallel sides. The cutting blade 2 of this invention is rectangular in shape, and the serrations 23 on both sides along its length facilitate the thorough crushing of tobacco stems. If the serrations 23 on one side of the cutting blade 2 show significant wear, the installation direction of the cutting blade 2 can be reversed so that the serrations 23 on the other side of the cutting blade 2 can crush the serrations 23, thereby extending the service life of the cutting blade 2 and reducing processing costs.

[0029] A nut 6 is screwed onto the end of the through rod 3, and the nut 6 abuts against the spacer 4. To prevent relative movement of the through rod 3 within the through hole 22, a nut 6 is installed at the end of the through rod 3, and the nut 6 is attached to the spacer 4 to fix the through rod 3. To further enhance the fixation, a first through hole is provided on the through rod 3, and a second through hole is provided on the nut 6. A fixing pin 5 passes through the first and second through holes, and the relative position of the nut 6 and the through rod 3 can be locked by the fixing pin 5, which can improve the stability of high-speed operation during the high-speed rotation of the roller main shaft 1.

[0030] Nine sets of perforations 22 are evenly spaced on the partition plate 4 of this utility model. Nine sets of through rods 3 are circumferentially installed on the roller assembly. At most, three sets of blades 2 can be installed on each set of through rods 3 and between each set of partition plates 4. A maximum of 24 sets of blades 2 can be installed on a single through rod 3. Since this utility model is easy to disassemble, the number of blades 2 on the through rod 3 can be adjusted by removing the nut 6 and the fixing pin 5, thereby flexibly adjusting the particle size of the crushing. If there are more blades 2, the mesh size of the crushing will be lower.

[0031] The cutting tool 2 is made of 65Mn, which has a certain degree of toughness, reducing the probability of breakage during processing. The weight-reducing holes 21 on the cutting tool 2 are elongated to maximize their area to match the rectangular blade structure. Furthermore, through holes 22 on both sides of the weight-reducing holes 21 allow for reversing the installation orientation of the cutting tool 2, enabling repeated use of the serrations 23 on both sides.

[0032] 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.
