Description
Technical Field
[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a guide roller for tobacco leaf shredding with adjustable blades. Background Technology
[0002] In the field of cigarette re-drying and leaf trimming, leaf shape is a crucial preliminary step to ensure the quality of subsequent processing. The guide roller for tobacco leaf trimming is a core component for this process, and its structural design directly affects efficiency and leaf shape. Existing tobacco leaf trimming guide rollers mostly employ an integrated structure with the guide roller and cutter head fixedly connected, and the blades on the cutter head are typically fixedly installed.
[0003] This type of structure has a significant drawback: when the blade is worn or damaged, because the blade and the cutter head are not detachable, it is difficult to replace the damaged part separately, and the whole thing must be scrapped, which increases maintenance costs and wastes resources. Utility Model Content
[0004] In view of this, this application proposes a guide roller for tobacco leaf shredding with adjustable blades, which has an adjustable blade spacing and a significant effect on improving the yield of medium-sized leaves.
[0005] This utility model provides the following technical solution: a guide roller for shredding tobacco leaves with adjustable blades, characterized in that it includes: a guide roller body; The guide roller has a solid cylindrical structure, and a positioning groove is provided on the guide roller along the circumferential direction; A cutter disc is inserted into the guide roller, and the cutter disc is detachably connected to the guide roller through the positioning groove; The cutter head is equipped with multiple blades that are evenly distributed along the circumference of the cutter head. Each blade has a mounting hole at its end, and the cutter head has a threaded hole at a corresponding position on its outer circumference. The blades are detachably connected to the cutter head by bolts.
[0006] In one embodiment of the utility model, the positioning groove has a triangular cross-sectional shape and extends from one end of the guide roller along the axial direction of the guide roller to the other end.
[0007] In one embodiment of the utility model, there are six positioning grooves, which are evenly spaced and divide the guide roller into six equal parts along the circumference.
[0008] In one embodiment of the utility model, there are multiple cutter discs, which are uniformly arranged along the axial direction of the guide roller.
[0009] In one embodiment of the utility model, a screw is also included, the screw tip being triangular in shape and cooperating with the shape of the positioning groove.
[0010] In one embodiment of the utility model, the cutter disc is a ring-shaped structure with a certain thickness, and the cutter disc has a through hole along the circumferential direction, the size of which matches the positioning groove.
[0011] In one embodiment of the utility model, the blade is a rectangular thin sheet structure, and the end of the blade away from the mounting hole is an arc-shaped structure.
[0012] In one embodiment of the utility model, the outer circumferential surface of the guide roller is uniformly provided with external threads along the axial direction of the guide roller, and the inner edge surface of the cutter disc is uniformly provided with internal threads. The size of the internal threads matches the external threads, and is used to insert the cutter disc onto the guide roller.
[0013] In one embodiment of the utility model, the cutter head can rotate relative to the guide roller along the axial direction of the guide roller.
[0014] In one embodiment of the utility model, the positioning groove is located on the outer peripheral surface of the guide roller and extends toward the axis of the guide roller.
[0015] The beneficial effects of this invention are as follows: By creating circumferential positioning grooves on the guide rollers and detachably connecting them with through holes in the cutter disc, precise positioning of the cutter disc and guide rollers can be quickly achieved. This simplifies the installation and disassembly process of the cutter disc, facilitating future maintenance and replacement, effectively reducing equipment downtime and lowering operating costs. Multiple blades are evenly inserted around the circumference of the cutter disc, ensuring uniform force on the tobacco leaves during crushing and preventing insufficient or excessive crushing in certain areas. Furthermore, the blades and cutter disc are detachably connected by bolts, allowing for direct replacement of rusted blades while retaining the original cutter disc, saving costs. In addition, the combination of a detachable cutter disc and multiple blades allows for flexible adjustment of the number of blades or replacement of the cutter disc according to the humidity, thickness, and other characteristics of different tobacco leaves, meeting diverse tobacco leaf crushing needs, enhancing the equipment's applicability, and providing a more efficient and flexible solution for tobacco processing.

[0022] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.
[0023] Specific references Figure 1As a guide roller for tobacco leaf shredding with adjustable blades according to this utility model, the device includes: a guide roller body 1; the guide roller 1 is a solid cylindrical structure with a positioning groove 11 opened along its circumferential direction; a cutter disc 2 is inserted on the guide roller 1, the cutter disc 2 is a circular annular structure with a certain thickness, and a through hole with a size matching the positioning groove 11 is opened along its circumferential direction, so that the cutter disc 2 and the guide roller body 1 can be detachably connected through the cooperation of the through hole and the positioning groove 11; there are multiple blades 21, which are evenly distributed along the circumference of the cutter disc 2 and are detachably connected to the cutter disc 2.
[0024] In one specific embodiment, the guide roller body 1 is made of metal and can withstand the continuous impact during the tobacco leaf beating process. The specific dimensions of the guide roller body 1 can be set according to equipment requirements, with a length approximately 5-10 times its diameter. The solid structure design ensures that there is no eccentric vibration during high-speed rotation. A positioning groove 11 is formed on the outer circumference of the guide roller body 1, penetrating both ends of the guide roller 1. The groove depth extends along the axis of the guide roller 1, with an extension depth of 1 / 5 of the diameter of the guide roller 1. The cross-sectional shape of the positioning groove 11 is triangular, and the triangular structure can prevent the cutter head 2 from rotating circumferentially on the guide roller 1. At the same time, the positioning groove 11 extends axially from one end of the guide roller body 1 to the other end, ensuring that the cutter head 2 can be adjusted along the entire length of the guide roller 1.
[0025] Furthermore, there are six positioning grooves 11, which are evenly spaced along the circumference of the guide roller body 1, dividing the outer circumference of the guide roller into six equal parts, with an included angle of 60° between adjacent grooves. This design allows for the selection of different grooves for positioning during the installation of the cutter head 2, flexibly adjusting the circumferential angle of the cutter head 2. At the same time, the distribution of multiple grooves allows for more even force distribution on the cutter head 2, reducing wear on individual grooves.
[0026] In one specific embodiment, the cutter head 2 has a ring-shaped structure, with its inner diameter fitting closely to the outer diameter of the guide roller body 1, ensuring smooth sliding of the cutter head 2 along the guide roller body 1 without jamming or offset. The cutter head 2 is fixed to the guide roller body 1 using screws 12. The tip shape of the screw 12 perfectly matches the triangular cross-section of the positioning groove 11. After the cutter head 2 is adjusted to the target position, the screw 12 is passed through the pre-drilled hole 22 on the side wall of the cutter head 2 and screwed into the positioning groove 11. The tip fits tightly against the inner wall of the groove 11, effectively preventing axial or circumferential displacement of the cutter head 2 when the guide roller 1 rotates. Disassembly involves unscrewing the screw 12 to move the cutter head 2 along the guide roller, significantly reducing equipment maintenance time.
[0027] In one specific embodiment, the blade 21 is a rectangular thin sheet structure. One end of the blade 21 has a mounting hole 23, and a corresponding threaded hole is formed on the outer circumference of the cutter disc 2. A bolt is passed through the mounting hole 23 and screwed into the threaded hole to secure the blade 21. When the blade 21 is worn or damaged, the bolt can be unscrewed to replace the individual blade, eliminating the need to scrap the entire cutter disc 2. Replacing a single set of blades 21 reduces costs. Furthermore, the end of the blade 21 furthest from the mounting end is designed with an arc shape. This arc shape prevents tobacco fibers from getting caught on the blade during the shredding process, reducing blade entanglement and ensuring uniformity of the shredded tobacco.
[0028] Furthermore, the number of blades 21 on each cutter disc 2 can be adjusted according to the pulverizing requirements, typically 4-6, with equal spacing angles between adjacent blades 21. The evenly distributed blades 21 ensure uniform force distribution as the tobacco leaves pass through the guide rollers, preventing insufficient or excessive pulverization in certain areas.
[0029] In one specific embodiment, there are multiple cutter discs 2, which are evenly arranged along the axial direction of the guide roller 1. The outer circumferential surface of the guide roller 1 is uniformly provided with external threads along the axial direction, and the inner edge surface of the cutter discs 2 is correspondingly provided with internal threads, the specifications of which are perfectly matched. When it is necessary to adjust the spacing between adjacent cutter discs 2, the cutter discs can be rotated clockwise or counterclockwise to move along the axis of the guide roller 1, meeting the requirements for shredding tobacco leaves of different thicknesses. For example, when processing thicker tobacco leaves, the spacing between adjacent cutter discs 2 can be increased to prevent tobacco leaves from clogging between the discs; when processing thinner tobacco leaves, the spacing between adjacent cutter discs 2 can be decreased to ensure that the tobacco leaves are fully shredded.
[0030] The working process of multiple cutter discs 2 is as follows: First, the equipment can be adjusted according to the state of the tobacco leaves to be processed. When the tobacco leaves are thick, the distance between adjacent cutter discs 2 is increased, and when the tobacco leaves are thin, the distance between adjacent cutter discs 2 is shortened. After the adjustment is completed, the cutter discs 2 are fixed on the guide rollers 1 with screws 12. The tobacco leaves are conveyed from the feed port of the equipment to the top of the guide rollers 1. The guide rollers 1 rotate at high speed, driving the cutter discs 2 and the blades 21 to rotate synchronously. Finally, the crushed tobacco leaves are discharged from the discharge port below the guide rollers.
[0031] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
