Abstract
Description
Technical Field
[0001] This application belongs to the field of tobacco processing technology, specifically relating to a guide bar for a shredder and a shredder. Background Technology
[0002] Traditional tobacco shredders use a rotary cutter system, with N (usually 10 or 8, etc.) blades evenly arranged on a high-speed rotating roller. Guide strips are installed below the blades to create space for the tobacco shredder. However, as the tobacco shreds pass through this space, they scrape against the walls, accumulating tar, soot, and other impurities throughout the production process. This eventually forms a large, thick layer of tar. This tar layer detaches from the space as the blades feed and falls into the shredded tobacco, affecting both the purity of the tobacco and significantly impacting subsequent drying and air-separation processes. Furthermore, cleaning the accumulated tar and soot on the guide strips requires substantial manual maintenance work for the shredder operators, disrupting the machine's continuous operation. Utility Model Content
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0004] Therefore, the first aspect of this utility model provides a wire guide for a wire cutter.
[0005] The second aspect of this utility model provides a shredder.
[0006] In view of this, a wire guide bar for a shredder is provided according to a first aspect of the embodiments of this application, comprising: The guide bar body is arranged between the cutter roller and the cutter along the axial direction of the cutter roller; The guide bar body includes a feeding end, a guiding end, and a first guiding surface. The first end of the feeding end is connected to the first end of the first guiding surface, and the second end of the feeding end is connected to the cutter. The first end of the guiding end is connected to the second end of the first guiding surface, and the second end of the guiding end is connected to the cutter roller. The second end of the guiding end extends away from the first guiding surface. The guide wire texture is set on the first guide wire surface along the length direction of the guide wire body.
[0007] In one feasible implementation, the wire guide bar of the shredder further includes: The guide wire portion is embedded in the first guide wire surface and extends along the length direction of the guide wire strip body. The first end of the working surface of the guide wire section is connected to the first end of the feed end, and the second end of the working surface is connected to the first end of the guide wire section. The guide wire texture covers the working surface.
[0008] In one feasible implementation, the wire guide bar of the shredder further includes: The mounting groove extends through the main body of the guide wire along its length. The bottom surface of the mounting groove is parallel to the working surface, and the guide wire is embedded in the mounting groove.
[0009] In one feasible implementation, the guidewire portion and the guidewire strip body are an integral structure.
[0010] In one feasible implementation, the guidewire part and the guidewire strip body are separate structures, and the guidewire part and the guidewire strip body are detachably connected.
[0011] In one feasible implementation, the working surface is arc-shaped.
[0012] In one feasible implementation, the radius of curvature R of the working surface is 15mm ≤ R ≤ 20mm.
[0013] In one feasible implementation, the guidewire texture is honeycomb, striped, or a combination of honeycomb and striped.
[0014] In one feasible implementation, the wire guide bar of the shredder further includes: An anti-adhesion layer is provided at least on the first guidewire surface.
[0015] According to a second aspect of the embodiments of this application, a shredder is provided, comprising: a shredder guide bar as described in any of the above technical solutions.
[0016] The present application discloses a wire guide strip and a wire cutter, which, compared with the prior art, have the following advantages: The shredder guide bar provided in this application includes a first guide surface forming a shredder-containing space with a continuous guiding surface with the feeding end and the guiding end. By setting guide texture on the first guide surface, the adhesion force of tobacco shreds on the first guide surface is reduced, and tobacco oil and tar are prevented from continuously adhering to the wall of the shredder-containing space. This prevents tobacco shreds from sticking together and accumulating in the shredder-containing space, thereby inhibiting the generation and accumulation of tobacco oil strips from the root, which helps to improve the purity of the shredded tobacco shreds, improve the quality of the shredding process, and reduce the cost of manual maintenance.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0020] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0021] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0022] like Figure 1As shown, according to a first aspect of the embodiments of this application, a wire guide for a slicing machine is provided, comprising: a wire guide body 1 and a wire guide texture 2; the wire guide body 1 is disposed between the cutter roller and the cutter along the axial direction of the cutter roller; the wire guide body 1 includes a feeding end 11, a guiding end 12 and a first guiding surface 13, the first end of the feeding end 11 is connected to the first end of the first guiding surface 13, and the second end of the feeding end 11 is connected to the cutter; the first end of the guiding end 12 is connected to the second end of the first guiding surface 13, the second end of the guiding end 12 is connected to the cutter roller, and the second end of the guiding end 12 extends in a direction away from the first guiding surface 13; the wire guide texture 2 is disposed on the first guiding surface 13 along the length direction of the wire guide body 1.
[0023] The shredder guide bar provided in this application embodiment includes a first guide surface 13 forming a shredder space with a continuous guiding surface with the feeding end 11 and the guiding end 12. By setting the guide texture 2 on the first guide surface 13, the adhesion of tobacco shreds on the first guide surface 13 is reduced, and tobacco oil and tar are prevented from continuously adhering to the wall of the shredder space. This prevents tobacco shreds from sticking together and accumulating in the shredder space, thereby inhibiting the generation and accumulation of tobacco oil strips from the root, which helps to improve the purity of the shredded tobacco shreds, improve the quality of the shredding process, and reduce the cost of manual maintenance.
[0024] In some examples, the guide wire texture 2 can be fabricated using forming techniques such as laser etching and electrical discharge machining.
[0025] like Figure 2 and Figure 3 As shown, in one feasible embodiment, the wire guide bar of the wire cutter further includes: a wire guide portion 3; the wire guide portion 3 is embedded in the first wire guide surface 13, and the wire guide portion 3 extends along the length direction of the wire guide body 1; the first end of the working surface 5 of the wire guide portion 3 is connected to the first end of the feeding end 11, the second end of the working surface 5 is connected to the first end of the guiding end 12, and the wire guide texture 2 covers the working surface 5.
[0026] In this technical solution, by setting an independent guide wire part 3 embedded and fixed in the first guide wire surface 13, the guide wire area that is prone to wear and adhesion is modularized. On the one hand, the guide wire part 3 can be made of a more wear-resistant or more anti-sticking material, reducing the overall manufacturing cost of the guide wire strip. On the other hand, when the guide wire texture 2 on the working surface 5 of the guide wire strip is worn or damaged due to long-term use, only the guide wire part 3 can be repaired or replaced, simplifying the maintenance process of the guide wire strip and reducing maintenance time and cost.
[0027] like Figure 2 As shown, in one feasible embodiment, the wire guide of the wire cutter further includes: a mounting groove 4; the mounting groove 4 extends through the wire guide body 1 along the length direction of the wire guide body 1, the bottom surface of the mounting groove 4 is parallel to the working surface 5, and the wire guide part 3 is embedded in the mounting groove 4.
[0028] In this technical solution, the guide wire part 3 is embedded in the mounting groove 4. The mounting groove 4 provides a precise and reliable installation positioning reference for the guide wire part 3. After installation, the working surface 5 of the guide wire part 3 can match the path of the original first guide wire surface 13 of the guide wire body 1. By making the bottom surface of the mounting groove 4 parallel to the working surface 5, the thickness of the guide wire part 3 is made consistent, reducing the production and processing difficulty of the guide wire part 3.
[0029] Furthermore, the width of the mounting groove 4 gradually increases from the top to the bottom of the groove to form a limiting space within the mounting groove 4. The bottom of the guide wire part 3 extends into the limiting space, which helps to improve the stability of the connection between the guide part and the guide wire body 1.
[0030] In one feasible implementation, the guide wire portion 3 and the guide wire body 1 are an integral structure.
[0031] In this technical solution, the wire guide part 3 and the wire guide strip body 1 are integrally formed, which reduces the assembly gap between the wire guide part 3 and the wire guide strip body 1, making the overall structure of the wire guide strip more rigid and strong, and having higher reliability and stability in the vibration environment of the high-speed operation of the wire cutter roller; at the same time, it eliminates the assembly error between the wire guide part 3 and the wire guide strip body 1, ensuring the accurate position of the working surface 5, which is conducive to improving the quality stability of the mass production of the wire guide strip.
[0032] In one feasible implementation, the guide wire part 3 and the guide wire strip body 1 are separate structures, and the guide wire part 3 and the guide wire strip body 1 are detachably connected.
[0033] In this technical solution, the guide wire part 3 and the guide wire strip body 1 adopt a detachable split structure. When the working surface 5 is worn or the guide wire part 3 with different textures and materials needs to be replaced, it is not necessary to replace the entire guide wire strip. Only the guide wire part 3 needs to be disassembled and assembled, which improves the convenience of guide wire strip maintenance and reduces the use and maintenance cost of guide wire strip.
[0034] like Figure 2 As shown, in one feasible implementation, the working surface 5 is arc-shaped.
[0035] In this technical solution, the working surface 5 is designed as an arc shape, and the curved surface structure guides the falling tobacco, reducing the retention and bouncing of the tobacco, so that the tobacco can be smoothly discharged, further reducing the risk of tobacco adhesion caused by collision and friction.
[0036] Furthermore, the discharge end extends tangentially along the arc-shaped working surface 5, and the feed end 11 extends radially along the arc-shaped working surface 5; the length of the feed end 11 extending radially along the arc-shaped working surface 5 is less than the length of the discharge end extending tangentially along the arc-shaped working surface 5.
[0037] In one feasible implementation, the radius of curvature R of the working surface 5 is 15mm ≤ R ≤ 20mm.
[0038] In this technical solution, the radius of curvature R of the working surface 5 is 15mm~20mm to prevent the tobacco from flowing poorly due to the curvature of the working surface 5 being too small, while preventing the curvature of the working surface 5 from weakening the guiding and holding effect on the tobacco, ensuring that the tobacco passes through the guide strip with minimal resistance and maximum efficiency, thus balancing the guiding and holding functions of the guide strip.
[0039] As a preferred option, the radius of curvature R of the working surface 5 is 18.5 mm.
[0040] In one feasible implementation, the guide wire texture 2 is honeycomb-shaped, striped, or a combination of honeycomb-shaped and striped.
[0041] In this technical solution, the honeycomb texture can separate the attached e-liquid into each cell, thereby preventing e-liquid and tar from sticking together; the striped texture can guide the material to slide in an orderly manner along a specific direction. Through the combined synergistic effect of the honeycomb and striped textures, the continuity of the e-liquid film is disrupted to the maximum extent, resulting in a more significant and reliable anti-sticking effect.
[0042] In one feasible implementation, the wire guide bar of the shredder further includes: an anti-sticking layer; the anti-sticking layer is at least disposed on the first wire guide surface 13.
[0043] In this technical solution, by setting an anti-adhesion layer on the first guide wire surface 13, the anti-adhesion layer and the guide wire texture 2 form a dual anti-adhesion mechanism that combines physical and chemical properties. The guide wire texture 2 disrupts the adhesion over a large area, and the anti-adhesion layer reduces the adhesion at the microscopic level. The anti-adhesion layer and the guide wire texture 2 work together to make the anti-adhesion effect of the guide wire strip durable and efficient.
[0044] Furthermore, the anti-sticking layer also covers the entire guide strip body 1 and all the parts on the guide strip body 1, further reducing the adhesion and accumulation of tobacco shreds in the shred space during the shredding process, thereby further preventing the formation of larger e-liquid strips.
[0045] In some examples, the anti-stick layer is a polytetrafluoroethylene (PTFE) coating.
[0046] According to a second aspect of this application, a shredder is proposed, comprising: a shredder guide bar as described in any of the above technical solutions.
[0047] The shredder provided in this application includes the shredder guide bar of any of the above technical solutions, and therefore has all the beneficial effects of the shredder guide bar of the above technical solutions, which will not be elaborated here.
[0048] Specifically, a shredder can include a rotary shredder.
[0049] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.
[0050] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
