Abstract
Description
Technical Field
[0001] The utility model relates to an adjusting tool, in particular to a starting rail adjusting tool. Background Art
[0002] The YJ27 assembler's splicing and forming system receives single-length cigarettes from the cigarette supply system, double-length filter segments from the filter supply system, and standard paper sheets glued by the tipping paper supply system. Various cigarette materials converge here. In the production process, it is often encountered that the unit changes the cigarette brand or changes the tipping paper of the same brand from different manufacturers and different batches. There will be different thicknesses of the tipping paper, or different smoothness of the outer surface of the tipping paper. When producing thin cigarettes, the requirements for this gap will be higher. Since the spacing between the starting rail and the splicing drum groove is the cigarette diameter minus 0.7mm, which is smaller than the cigarette diameter and has a certain amount of compression, the starting rail brings the "cigarette group" out of the wheel groove and rolls the "cigarette group" between the arc surface of the splicing drum and the washboard, so that the tipping paper sheets tightly wrap and bond the "cigarette group" to form double-filter cigarettes. When the "cigarette group" rolls, the heated washboard causes the glue on the tipping paper sheets to dry instantly.
[0003] The start rail is fastened to the washboard by 4 M4×8 screws. The gap between the start rail and the wheel groove of the splicing drum is adjusted up and down through the four long holes on the start rail. The diameter of the splicing drum is 258mm and the wheel groove depth is 0.6mm. Use the hand wheel to turn the equipment. When the center of a drum groove on the splicing drum is located on the line connecting the start rail edge and the splicing drum center, stop turning the machine, loosen the 4 M4×8 screws that fasten the start rail, put a measuring rod in the splicing drum groove, make the start rail edge close to the measuring rod, and then tighten the screws. In the actual adjustment process, there are the following problems: First, the adjustment operation is inconvenient. Due to the use of a cylindrical measuring rod, the start rail edge and the measuring rod are in line contact. The splicing drum groove is shallow, only 0.6mm. When the start rail fastening screws are loosened and the start rail is pushed upward to the measuring rod, the measuring rod is very easy to fall or slip out of the splicing drum groove. In addition, the adjustment needs to be performed at the working temperature of the washboard. If you are not careful, there will be a risk of burns, which increases the difficulty of adjustment. Second, the accuracy of the adjustment result is poor. It is very difficult to make the center of the splicing drum wheel groove be located on the line connecting the splicing drum center and the starting rail edge by visual inspection alone. According to the calculation results, if the splicing drum wheel groove center deviates from the line connecting the splicing drum center and the starting rail edge by 0.5°, the gap deviation between the starting rail and the splicing drum wheel groove is -0.31mm. If the splicing drum wheel groove center deviates from the line connecting the splicing drum center and the starting rail edge by 1°, the gap deviation between the starting rail and the splicing drum wheel groove is -1.7mm. The adjustment of conventional cigarettes usually uses a 4.8mm measuring rod, which deviates by -0.20mm and -0.89mm respectively in the case of 0.5° and 1° angle deviation. It can be seen that under the same angle deviation, the deviation of thin cigarettes is greater, so the accuracy required when adjusting the gap of thin cigarettes is higher. In order to ensure the adjustment accuracy as much as possible, it is necessary to adjust and inspect repeatedly each time, which affects the effective operation time of the machine. According to statistics, the process of adjusting the starting rail takes at least 30 minutes. Utility Model Content

[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.
[0016] Embodiments of the present utility model: Figure 1 and Figure 2 As shown, a starting rail adjustment tool includes a first measuring rod 3 and a second measuring rod 4 placed between the rubbing drum 1 and the washboard 2, the first measuring rod 3 and the second measuring rod 4 are respectively located in two adjacent wheel grooves 5 on the rubbing drum 1, the first measuring rod 3 and the second measuring rod 4 are fixedly connected by an arc-shaped connecting plate 6, and the outer surface of the arc-shaped connecting plate 6 abuts against the cutting edge of the starting rail 7 on the washboard 2.
[0017] The radius of the splicing drum 1 is 129 mm, and 22 wheel grooves 5 are evenly formed on the circumferential surface of the splicing drum 1, and the depth of the wheel grooves 5 is 0.6 mm. Through the cooperation of the first measuring rod 3 and the second measuring rod 4 with the wheel grooves 5, the arc-shaped connecting plate 6 can be positioned so that the arc-shaped connecting plate 6 is coaxial with the splicing drum 1, so that when adjusting, it is only necessary to make the cutting edge of the starting rail 7 abut against the outer arc surface of the arc-shaped connecting plate 6 to achieve precise adjustment.
[0018] Specifically, in this embodiment, the diameters of the first measuring rod 3 and the second measuring rod 4 are equal, and both of them have a diameter of 4.8 mm. Because the optimal clearance between the cutting edge of the starting rail 7 and the groove bottom of the wheel groove 5 is 4.8 mm, a measuring rod with a diameter of 4.8 mm is selected.
[0019] In order to adjust the above-mentioned optimal gap, the radius of the outer arc surface of the arc connecting plate 6 is 129+4.8-0.6=133.2mm. The outer arc surface of the arc connecting plate 6 is tangent to the first measuring rod 3 and the second measuring rod 4, and the inner arc surface of the arc connecting plate 6 only needs to interfere with the outer surface of the rubbing drum 1, and the strength of the tooling is increased as much as possible without interference. In this embodiment, the radius of the inner arc surface of the arc connecting plate 6 is preferably 130mm.
[0020] Furthermore, the radius of the arc where the center of the first measuring rod 3 and the second measuring rod 4 are located is 129-0.6+4.8 / 2=130.8mm. The center distance between the first measuring rod 3 and the second measuring rod 4 is L=2R*Sin(A / 2)=2*130.8*Sin(16.36 / 2)=37.22mm.
[0021] Further, a handle 8 is formed at one end of the arc-shaped connecting plate 6, and a heat-insulating rubber sleeve is sleeved on the handle 8. The setting of the handle 8 can facilitate the installation and removal of the tooling, and the heat-insulating rubber sleeve can solve the problem of scalding when heat is transferred.
[0022] Working principle of the utility model: When the utility model is used, the wheel grooves 5 of the two adjacent wheels on the rubbing drum wheel 1 corresponding to the start rail 7 are cleaned, the first measuring rod 3 and the second measuring rod 4 are placed in the two cleaned wheel grooves 5, and the four M4×8 fastening screws on the start rail 7 are loosened to make the cutting edge of the start rail 7 close to the outer arc surface of the arc connecting plate 6 in the entire length direction, and then the four M4×8 fastening screws are fastened to complete the adjustment of the start rail 7. Through use verification, the adjustment of the start rail 7 using the utility model can be completed in 5 minutes instead of the original 30 minutes.
[0023] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings.
