Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for tobacco production equipment, and in particular to a tooling for adjusting a washboard starter rail. Background Technology

[0002] During the cigarette splicing process, the distance between the starting rail of the splicing plate and the cigarette receiving groove in the splicing drum must be precisely adjusted to meet the quality requirements of cigarette splicing.

[0003] In related technologies, during adjustment, a calibration rod is first placed in the smoke-receiving groove. Then, the position of the rubbing plate starting rail is adjusted and fixed so that the cutting edge of the rubbing plate starting rail contacts the calibration rod, thereby adjusting the position of the rubbing plate starting rail. In actual adjustment, firstly, the center of the smoke-receiving groove of the rubbing drum needs to be located on the line connecting the center of the rubbing drum and the cutting edge of the rubbing plate starting rail. This makes adjustment time-consuming and difficult to ensure accuracy. Secondly, during actual adjustment, when the rubbing plate starting rail is released and moved towards the calibration rod, the calibration rod is prone to wobbling, leading to reduced adjustment accuracy. Finally, after adjustment using this method, repeated verification is required, making the adjustment process time-consuming and labor-intensive. Therefore, a tooling that can provide stable and precise adjustment is urgently needed. Utility Model Content

[0027] like Figure 4 As shown, the rubbing mechanism includes a rubbing drum and a rubbing plate located on the lower left side of the rubbing drum. The rubbing plate is connected to the frame by screws, and a rubbing plate start rail is mounted on the rubbing plate by screws, with the cutting edge of the rubbing plate start rail facing the rubbing drum. Multiple smoke-collecting grooves are spaced apart on the outer wall of the rubbing drum for holding cigarettes. During adjustment, the rubbing plate start rail is loosened, and then its cutting edge is pushed towards the smoke-collecting groove.

[0028] In related technologies, when adjusting the distance between the cutting edge and the smoke receiving groove, a calibration rod is placed inside the smoke receiving opening. Then, the screws on the washboard starting rail are loosened, and the cutting edge is moved to make contact with the calibration rod. This method requires maintaining the stability of the calibration rod and ensuring line contact between the cutting edge and the calibration rod for adjustment. The adjustment process requires repeated operations, which is time-consuming and labor-intensive. Furthermore, because the contact is line-based, the calibration rod is prone to wobbling, leading to a decrease in calibration accuracy.

[0029] Regarding the problems in related technologies, such as Figure 1 , Figure 2 As shown, this utility model provides a tooling for adjusting the starting rail of a corrugated board, including a tooling plate 2. The tooling plate 2 has an arc-shaped structure. One side of the tooling plate 2 has a convex arc-shaped contact surface 22, and the other side of the tooling plate 2 has a concave arc-shaped limiting surface 23. Protruding locking portions 21 are formed on the opposite edges of the limiting surface 23. The corrugated board 3 is located below the left side of the corrugating drum 1, and the corrugated board starting rail 31 is mounted on the corrugated board 3. When adjusting the cutting edge of the corrugated board starting rail 31, the distance between the cutting edge and the smoke-collecting groove needs to be adjusted to achieve a suitable distance so that the corrugating drum 1 can rotate to achieve the corrugation of the cork paper. In this embodiment, through the overall structure of the tooling plate 2, the cutting edge of the corrugating starting rail contacts the contact surface 22 during adjustment, thereby achieving adjustment and improving adjustment efficiency and accuracy.

[0030] Specifically, the tooling plate 2 has a tile-like structure. Engaging parts 21 are provided on both sides of the limiting surface 23 of the tooling plate 2. These engaging parts 21 connect the tooling plate 2 to the forming drum 1, allowing adjustment after the cutting edge contacts the limiting surface 23. Specifically, the overall thickness of the tooling plate 2 is controlled so that after the tooling plate 2 is installed on the forming drum 1, the contact surface 22 is located on the surface where the cutting edge contacts the cigarette during operation. This ensures that after the engaging part 21 engages with the cigarette receiving groove, the contact surface 22 serves as a reference surface for adjustment, thereby improving adjustment accuracy and efficiency.

[0031] Understandably, in conventional techniques, when adjusting the blade position using a calibration rod, it is difficult to achieve rapid and stable adjustment due to the poor stability of a single calibration rod. In this embodiment, the solution has two locking parts 21, which engage with the smoke-collecting groove on the rubbing drum 1, thereby ensuring that the tooling plate 2 is stably mounted on the rubbing drum 1. Furthermore, by controlling the dimensions of the tooling plate 2, the contact surface 22 replaces the calibration position of the calibration rod, thus achieving efficient and precise adjustment and improving the adjustment quality and efficiency.

[0032] According to some embodiments provided by this utility model, the snap-fit ​​part 21 is constructed as an arc-shaped structure. Cigarettes are usually cylindrical in shape, and correspondingly, in order to better hold the cigarettes, the cigarette receiving groove is also set as a circular slot structure. In this embodiment, by constructing the snap-fit ​​part 21 as an arc-shaped structure, it can fit snugly with the cigarette receiving groove, thereby improving the stability of the snap-fit ​​and reducing the dimensional error after snap-fit.

[0033] In conjunction with the above embodiments, the diameter of the snap-fit ​​part 21 is the same as the diameter of the smoke-collecting groove on the twisting drum 1. Multiple smoke-collecting grooves are spaced apart on one circumference of the twisting drum 1, and by setting the diameter of the snap-fit ​​part 21 to be the same, it becomes more stable after snap-fitting.

[0034] In a specific configuration, the diameter of the latching part 21 is 8mm. Currently, the standard diameter of cigarettes produced is generally 7.8mm, while the diameter of the cigarette receiving groove is set to 8mm. Therefore, by limiting the diameter of the latching part 21 to 8mm, it can be better suited for the production of cigarettes with a standard diameter of 7.8mm.

[0035] In some embodiments, the curvature between the two snap-fit ​​portions 21 is equal to the curvature of the two adjacent smoke-collecting grooves. During the installation of the tooling plate 2, the snap-fit ​​portions 21 need to be snapped into the smoke-collecting grooves to achieve stable installation. In this embodiment, by limiting the curvature between the snap-fit ​​portions 21, the snap-fit ​​installation of the tooling plate 2 can be facilitated, improving its applicability.

[0036] Specifically, multiple smoke-collecting grooves are evenly arranged on the rubbing drum 1, and the two adjacent smoke-collecting grooves have the same curvature. In this embodiment, by snapping the snap-fit ​​part 21 into the two adjacent smoke-collecting grooves, the contact surface 22 is used as the reference surface for the contact of the cutting edge, so that the position of the cutting edge can be adjusted at any position on the contact surface 22, thereby improving the efficiency and accuracy of the adjustment.

[0037] In a specific configuration, the snap-fit ​​part 21 is integrally formed with the tooling plate 2. This integral forming design improves its structural strength and thus enhances its stability.

[0038] In some specific embodiments, the snap-fit ​​portion 21 extends along the length direction of both sides of the tooling plate 2. The snap-fit ​​portion 21 extends along the length direction to form a cylindrical structure. In this way, the snap-fit ​​portion 21 can fill the entire smoke receiving groove after snapping, thereby improving the stability of the snap-fit.

[0039] In practical applications, the contact point between the snap-fit ​​part 21 and the contact surface 22 is constructed as an arc-shaped surface. This arc-shaped surface design avoids stress concentration, improves the overall structural strength, and extends its service life.

[0040] In some embodiments, the radius of curvature of the contact surface 22 is greater than the radius of curvature of the limiting surface 23. The curvature of the contact surface 22 needs to conform to the annular surface formed by the cigarettes in the working state (that is, the annular surface formed by the outermost contour line of the exposed part of the cigarettes when multiple cigarettes are placed in the cigarette receiving groove), so its curvature is greater than the curvature of the limiting surface 23.

[0041] In a specific implementation, the tooling plate 2 is an alloy plate. The alloy plate provides structural strength, resulting in greater overall stability.

[0042] like Figure 3 As shown below, the dimensional design of the adjustment tooling will be explained through specific embodiments.

[0043] Currently, the standard diameter of cigarettes produced is generally 7.8mm. According to the technical requirements of the equipment, the distance between the flushing plate starting rail 31 and the cigarette receiving groove of the flushing drum 1 should be the cigarette diameter minus 0.7mm. The thickest point dimension 'a' of the simple tooling adjustment plate is 7.1mm. The specific design and processing procedures are as follows: like Figure 3 As shown, 22 smoke-collecting grooves are evenly arranged around the outer wall of the rubbing drum 1. The arc angle θ between adjacent smoke-collecting grooves is: 360°÷22=16.36360. This dimension determines the relative distance between the two snap-fit ​​parts 21.

[0044] The radius R0 of the rubbing drum 1 is measured to be 129mm. The 22 smoke-collecting grooves evenly distributed on the circumference of the rubbing drum 1 have a radius of 4mm and a groove depth of 0.8mm. The gap between the rubbing plate starting rail 31 and the bottom of the smoke-collecting groove is 7.1mm. The distance R2 from the cutting edge of the rubbing plate starting rail 31 to the center of the rubbing drum 1 should be: 129+7.1-0.8=135.3mm. Thus, the radius of the arc of the outer contour of the tooling plate 2 is determined, that is, the distance from the outer surface of the contact surface 22 to the center of the rubbing drum 1 is 135.3mm.

[0045] Since the radius of the smoke receiving groove is 4mm, the gap R1 between the center of the smoke receiving groove and the rubbing drum 1 is: 129 + 4 - 0.8 = 132.2mm. This determines the inner arc radius of the adjusting plate of the adjusting fixture, which is also the arc radius of the limiting surface 23.

[0046] Then, with the center of the rubbing drum 1 as the center, draw a relative angle line with an angle θ of 16°36′. Draw an inner arc with a radius R1 of 132.2mm. The arc intersects with the center of the adjacent smoke receiving groove from the rubbing drum 1 to determine the positioning point for the tooling to combine with the smoke receiving groove. Draw two circles with a radius of 4mm with the positioning point as the center to serve as the solid structure of the snap-fit ​​part 21. Draw an outer arc with a radius R2 of 135.3mm to form the contact surface 22 of the tooling plate 2, thereby forming the overall structure of the tooling plate 2.

[0047] When adjusting the washboard starting rail 31, first clean the smoke receiving groove, then snap the locking part 21 into the two adjacent smoke receiving grooves to install the tooling plate. After the tooling plate body 2 is installed, loosen the fastening bolts 32 of the washboard starting rail 31 so that the cutting edge of the washboard starting rail 31 is in close contact with the contact surface 22, and then tighten the bolts to complete the adjustment of the washboard starting rail 31.

[0048] Through the above description of the embodiments, those skilled in the art can clearly understand that by setting the snap-fit ​​part 21 on the tooling plate 2 in each embodiment, the snap-fit ​​part 21 is snapped into the smoke receiving groove during adjustment, thereby achieving that the distance between each position of the contact surface 22 and the smoke receiving groove is equal. This allows the spacing adjustment to be achieved as long as the cutting edge of the washboard starting rail 31 contacts the contact surface 22 during adjustment, thereby improving the adjustment accuracy and efficiency.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
