Description
Technical Field
[0001] The utility model relates to a calibration device for cigarette production equipment, in particular to a chopping knife disc adjustment and calibration device for a double-track suction guide rail of a cigarette making machine. Background Art
[0002] The tobacco-drawing and shaping process of the YJ116A cigarette-making machine is the primary feeding and supplying component of the cigarette-rolling process. It primarily absorbs and conveys tobacco, relying on a suction rail and a suction belt to deliver the tobacco. The suction rail is a dual-track system, employing three spaced-apart guides to form two parallel suction channels. Each channel is equipped with a splitter position, beneath which a splitter device is installed. The splitter device features two opposing apexes of the splitter discs, which serve as trimming points. These trimming points trim and shape the tobacco bundle conveyed from the tobacco-drawing channel, forming a tight cigarette tip. The trimmed tobacco bundle is then wrapped in cigarette paper to form a tobacco rod, which is then slit, filter-jointed, and wrapped in tipping paper.
[0003] In the double-channel wire suction guide, since the two wire suction channels share the same intermediate guide body, the installation space of the chopping knife device is limited. Therefore, the chopping knife positions of the two wire suction channels are staggered along the conveying direction. At the same time, the two chopping knife disks of each group of chopping knife devices are designed to be an inverted V-shaped taper setting, so that the relative vertices of the two chopping knife disks extend into the interior of the wire suction guide, which can avoid the interference of the wire suction guide on the chopping knife disk to a certain extent.
[0004] The distance between the trimming part of the chopping knife device and the suction ribbon in the suction channel is the height of the trimmed tobacco bundle. In the current equipment, the distance between the suction ribbon in contact with the porcelain beads in the suction channel and the trimming part of the chopping knife disk is relatively fixed; and due to the limited space at the bottom of the suction guide rail, the height position of the chopping knife disk can only be adjusted within a very small range, and there is no device to calibrate the height of the trimming part of the chopping knife disk after adjustment, so it is impossible to quickly and accurately determine whether the adjusted height of the trimming part of the chopping knife disk is accurate.
[0005] However, when factors such as the weight of individual cigarettes, tobacco structure, and cigarette diameter vary, the density distribution gradient of the tobacco bundle transported through the tobacco channel will vary, resulting in different required heights for the tobacco bundle after trimming by the splitter disc. Currently, there is no calibration device for the adjusted height of the splitter disc, making it impossible to quickly and accurately calibrate the height of the adjusted splitter disc, and thus, unable to provide high-quality trimming for each specific size of cigarette. When producing cigarettes of varying sizes, some sizes will have low density and insufficient tobacco filling at the tobacco bundle head, ultimately leading to loose ends and a high rejection rate of empty cigarettes. In actual production, the average empty cigarette rejection rate for YJ116A cigarette maker units from various manufacturers in the industry is around 0.4%, with the rejection of over 20,000 single-item waste products per shift significantly increasing waste and auxiliary material consumption during production.

DETAILED DESCRIPTION
[0029] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.
[0030] See also Figures 1 to 11The present embodiment provides a chopping disc adjustment and calibration device for a double-track wire suction guide rail of a cigarette making machine. The double-track wire suction guide rail includes two end guide rail bodies 1 located at both ends and an intermediate guide rail body 2 located in the middle. The channel between adjacent guide rail bodies forms a wire suction channel 3 extending in the front-to-back direction. Each wire suction channel 3 is provided with a chopping position 4. A chopping device 5 is provided below the chopping position 4 of each wire suction channel 3. The chopping device 5 includes two chopping discs 6 arranged opposite to each other on the left and right. The opposite apex portions of the two chopping discs 6 are trimming portions 7. A plurality of ceramic beads 8 are provided in the wire suction channel 3 along the front-to-back direction. The calibration device includes a calibration guide rail 9, a hanging structure is provided on the top of the calibration guide rail 9, the calibration guide rail 9 coincides with the chopping knife position 4 section of the wire suction channel 3, and the calibration guide rail 9 is detachably hung on the top of the wire suction channel 3 through the hanging structure. The top surface of the calibration guide rail 9 fits the bottom of the porcelain bead 8 at the chopping knife position 4 of the wire suction channel 3, and the bottom of the calibration guide rail 9 adsorbs the adjustment piece 10 through magnetic attraction. In this embodiment, a magnetic layer 11 is provided at the bottom of the calibration guide rail 9, and the adjustment piece 10 is a magnetic adjustment piece 10. The calibration guide rail 9 adsorbs the magnetic adjustment piece 10 through the magnetic layer 11 at the bottom.
[0031] Among them, the hanging structure includes two front and rear studs 12 arranged on the top of the verification guide rail 9, each stud 12 extends vertically upward above the wire suction channel 3 and is equipped with a hanging cover 13, and the hanging cover 13 is hung on the top surface of the guide rail body on both sides of the wire suction channel 3, and the hanging cover 13 is pressed against the top surface of the guide rail body by tightening the nut 14 on the stud 12, thereby realizing the vertical limitation of the verification guide rail 9 in the wire suction channel 3.
[0032] Two front and rear limit columns 15 are also provided on the top of the calibration guide rail 9. The front and rear limit columns 15 respectively fit in with the front and rear sides of the two front and rear porcelain beads 8 at the chopping knife position 4 of the wire suction channel 3 to resist, thereby limiting the front and rear directions of the calibration guide rail 9 in the wire suction channel 3.
[0033] The total height of the calibration rail 9 and the adsorbed adjustment piece 10 is called the calibration height. The calibration device can be adjusted to different calibration heights by adding or removing the adjustment piece 10. The calibration height H is calculated by formula (1):
[0034] H=(x / z)×d (1)
[0035] Where x is the fill value of the tobacco cut, z is the inherent fill value of the tobacco cut (4.6), and d is the diameter of the tobacco cut. Cigarettes of different sizes have different fill values x and diameters d, and therefore have different corresponding calibration heights H.
[0036] At the chopping position 4 of each wire suction channel 3, the middle guide rail body 2 is divided into two sections along the left and right directions, the section of the middle guide rail body 2 close to the chopping position 4 of the wire suction channel 3 is the inner section, and the section away from the chopping position 4 of the wire suction channel 3 is the outer section, and a first upwardly concave mounting groove is provided at the bottom of the outer section of the middle guide rail body 2, and a channel adaptability guide rail 16 is detachably installed in the first mounting groove at the bottom of the outer section of the middle guide rail body 2, and the channel adaptability guide rail 16 is provided with a concave arc-shaped guide groove 17 in the middle and lower section on the side facing the chopping position 4 of the wire suction channel 3, the length of the arc-shaped guide groove 17 extends along the front-to-back direction, and the arc-shaped guide groove 17 can completely cover the chopping disc 6 below in the length direction, and the side wall of the channel adaptability guide rail 16 on the side away from the chopping position 4 of the wire suction channel 3 constitutes the side wall of the lower section of the adjacent wire suction channel 3.
[0037] The channel adaptability guide rail 16 includes a channel adaptability guide rail body 18 located in the middle and flow guide blocking portions 19 located at the front and rear ends. An arcuate flow guide groove 17 is provided on the channel adaptability guide rail body 18. The front and rear ends of the arcuate flow guide groove 17 are closed by the front and rear flow guide blocking portions 19. The inner sides of the front and rear flow guide blocking portions 19 are respectively provided with spherical flow guide surfaces 20. The spherical flow guide surfaces 20 at both ends are smoothly transitioned to the front and rear ends of the arcuate flow guide groove 17. In this embodiment, the channel adaptability guide rail body 18 is detachably connected to the outer section of the intermediate guide rail body 2 by screw connection, that is, two first screws 21 are respectively passed upward through the two first mounting holes 22 on the channel adaptability guide rail 16 and then tightened into the threaded holes on the first mounting groove of the outer section of the intermediate guide rail body 2.
[0038] The channel-adaptive guide rail 16 provided in this embodiment features an arcuate guide groove 17 within its main body 18. This design not only increases the distance between it and the underlying cleaver disc 6, allowing ample room for height adjustment, but also diverts tobacco shreds that fly away from the cleaver disc 6 during rotation at the cleaver position 4, preventing localized accumulation of the shredded tobacco. Furthermore, spherical guide surfaces 20 are provided within the two guide blocking portions 19 to guide the tobacco and prevent shredded tobacco from flying off the brush wheel from interfering with the adjacent suction channel 3.
[0039] Multiple channel adaptability guide rails 16 of varying sizes can be designed to meet the high-quality trimming requirements for cigarettes of varying sizes. To quickly switch between different channel adaptability guide rails 16, simply remove the two first screws 21, replace the corresponding channel adaptability guide rail 16, and then tighten the two first screws 21.
[0040] At the chopping position 4 of each wire suction channel 3, a second upwardly recessed mounting groove is respectively provided at the bottom of the inner section of the middle guide rail body 2 and the bottom of the end guide rail body 1. Chopping knife adaptability guide rails 23 are respectively detachably mounted in the second mounting grooves at the bottom of the end guide rail body 1 and the middle guide rail body 2. The channel between the two chopping knife adaptability guide rails 23 constitutes the lower section of the chopping position 4 of the wire suction channel 3. The two chopping knife adaptability guide rails 23 are located on the left and right sides above the trimming part 7 of the two chopping knife discs 6 of the corresponding chopping knife device 5.
[0041] The cleaver adaptable guide rail 23 is generally L-shaped. The horizontal section of the cleaver adaptable guide rail 23 fits against the bottom surface of the second mounting groove and is removably connected to the corresponding guide rail body. In this embodiment, the horizontal section of the cleaver adaptable guide rail 23 is removably connected to the end guide body 1 or the inner section of the intermediate guide body 2 via screws. Specifically, two second screws 24 are inserted upward through the two second mounting holes 25 of the cleaver adaptable guide rail 23 and then tightened into the threaded holes in the corresponding second mounting groove. The channel between the two vertical sections of the cleaver adaptable guide rail 23 constitutes the lower section of the wire suction channel 3.
[0042] Multiple, different-sized cleaver adaptability rails 23 can be designed to meet the high-quality trimming requirements for cigarettes of varying sizes. To quickly switch between cleaver adaptability rails 23, simply remove the two second screws 24, replace the corresponding cleaver adaptability rail 23, and then tighten the two second screws 24.
[0043] When the equipment is operating normally, a suction ribbon is attached to each ceramic bead 8 in the suction channel 3. The ribbon slides along the roller surface of the ceramic bead 8. Under the action of negative pressure suction, the tobacco is adsorbed on the ribbon and clamped by the side surfaces of the guide bodies on both sides of the suction channel 3, transporting it from back to front. When the tobacco bundle is conveyed to the splitting position 4, the splitting device 5 is activated, and the two counter-rotating splitting discs 6 are used to trim the lower section of the tobacco bundle. The trimmed tobacco bundle continues to be transported forward in the suction channel 3.
[0044] When it is necessary to switch the size of cigarettes to be produced, the calibration height H for that size of cigarette is first calculated using the above formula 1. The number of adjustment tabs 10 at the bottom of the calibration guide 9 is then increased or decreased to ensure that the calibration height H of the calibration device reaches the calibration height value corresponding to that size of cigarette. The equipment is shut down, the suction belt is removed, and the calibration guide 9 is placed upwards into the suction channel 3 from the chopping position 4 until the top surface of the calibration guide 9 is aligned with the porcelain beads 8. Simultaneously, the two limit posts 15 are engaged with the front and rear sides of the two porcelain beads 8 in the suction channel, respectively. The mounting cover 13 is then placed on the studs 12 of the suction guide and the nuts 14 are tightened to complete the installation of the calibration device and the suction channel 3. The height of the two chopping discs 6 of the chopping device 5 is then adjusted until the distance between the top of the trimming area 7 of the two chopping discs 6 and the bottom of the lowest adjustment tab of the calibration guide 9 reaches a constant value. In this embodiment, this constant value is 0.3 mm. The distance between the top of the trimming portion 7 of the two riving discs 6 and the bottom of the lowest adjustment tab of the calibration guide 9 can be measured using a 0.3 mm thick feeler gauge. This distance is called the constant distance.
[0045] During the process of adjusting the height position of the two cleaver discs 6 of the cleaver device 5, if it is found that the channel adaptability guide rail 16 interferes with the cleaver discs 6, the channel adaptability guide rail 16 of appropriate specifications can be switched first, and then the height position of the two cleaver discs 6 can be adjusted until the two cleaver discs 6 reach the specified height position. After adjusting the height position of the cleaver discs 6, two cleaver adaptability guide rails 23 of appropriate specifications are selected and installed at the bottom of the inner section of the middle guide body 2 and the bottom of the end guide body 1, respectively, so that the bottom of the two cleaver adaptability guide rails 23 is exactly flush with the bottom of the lowest adjustment plate of the calibration guide rail 9, thus completing the adjustment of the appropriate height position of the two cleaver discs 6. After adjustment, the calibration height H of the calibration device plus the constant spacing of 0.3mm is the height of the tobacco bundle after being trimmed by the cleaver disc 6. The subsequent trimming of tobacco bundles of this specification ensures that the height of the trimmed tobacco bundles is of appropriate height, effectively reducing the phenomenon of large amounts of empty cigarette ends and empty cigarettes being rejected due to inappropriate trimming height. After actual application, the device has reduced the rejection rate of empty and loose cigarette ends to below 0.1%, greatly reducing the consumption of waste cigarettes and improving equipment operation efficiency.
[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
