Description

Technical Field

[0001] The invention relates to a calibration device for cigarette production equipment, in particular to an adaptability adjustment calibration device for a double-channel suction guide rail of a cigarette making machine. Background Art

[0002] The tobacco suction forming process of the YJ116A cigarette making machine is the main part of feeding and supplying tobacco in the cigarette rolling process. It mainly completes the adsorption and transmission functions of tobacco, and relies on the cooperation of the tobacco suction guide and the tobacco suction belt to complete the tobacco feeding process. The tobacco suction guide is a double-channel tobacco suction guide, which uses three guide bodies arranged at intervals to form two parallel tobacco suction channels. Each tobacco suction channel is provided with a splitting position, and a splitting device is installed below the splitting position. In the splitting device, the apex of the two splitting discs is the trimming position. The trimming parts of the two splitting discs are used to trim and shape the tobacco bundles transported from the tobacco suction channel and form the tight end of the cigarette. The trimmed tobacco bundles are subsequently wrapped with cigarette paper to form cigarette strips and then cut into cigarettes, dock the filters, and wrap with kraft paper.

[0003] In the double-channel wire suction guide, since the two wire suction channels share the same middle 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 belt in the suction channel is the height of the tobacco bundle after trimming. In the current equipment, the distance between the suction belt that fits 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, even if the height position of the chopping knife disk needs to be adjusted, it 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 a single cigarette, the structure of tobacco, and the diameter of the cigarette change, the density distribution gradient of the tobacco bundle transported in the tobacco channel will be different, and the height of the chopping disc of the existing equipment is relatively constant or can only be adjusted within a small range, that is, the height of the tobacco bundle trimmed by the chopping disc is constant or can only be adjusted within a small range. When corresponding to cigarettes of different specifications, it will cause the density of the tobacco bundle head of some specifications to be low and the tobacco filling amount at the tobacco bundle head to be insufficient, and eventually there will be problems such as loose ends of the cigarettes and a large amount of empty cigarettes being rejected. In addition, there is currently no calibration device for calibrating the height position of the chopping disc after adjustment, so it is impossible to quickly and accurately calibrate the height position of the adjusted chopping disc, and it is also impossible to perform high-quality pruning on various specifications of production cigarettes in a targeted manner. In the actual production process, the average empty cigarette rejection rate of the YJ116A cigarette citrus cigarette making machine of various manufacturers in the industry is about 0.4%, and the amount of waste rejected in a single shift exceeds 20,000 cigarettes, which greatly increases the waste and auxiliary material consumption in the production process of this model.

[0049] The channel adaptability guide rail 16 includes a channel adaptability guide rail body 18 located in the middle and a flow guide blocking portion 19 located at the front and rear ends. The arc flow guide groove 17 is arranged on the channel adaptability guide rail body 18. The front and rear ends of the arc flow guide groove 17 are closed by the front and rear two flow guide blocking portions 19. The inner sides of the flow guide blocking portions 19 at the front and rear ends are respectively provided with spherical flow guide surfaces 20.

[0050] The channel adaptability guide rail 16 provided in this embodiment has an arc-shaped guide groove 17 of the channel adaptability guide rail body 18, which can not only increase the distance between it and the chopping knife disk 6 below, leaving enough adjustment space for the height adjustment of the chopping knife disk 6, but also guide the tobacco shreds splashed when the chopping knife disk 6 rotates at the chopping position 4 to avoid local accumulation of the splashed tobacco shreds. At the same time, spherical guide surfaces 20 are respectively arranged on the inner sides of the two guide blocking parts 19 to guide the tobacco shreds and prevent the splashed tobacco shreds at the brush wheel from interfering with the adjacent suction channel 3.

[0051] According to the different specifications of cigarettes to be produced, a plurality of channel adaptability guide rails 16 of different specifications can be designed to meet the high-quality trimming requirements of cigarettes of different specifications. When switching channel adaptability guide rails 16 of different specifications, the two first screws 21 are unscrewed, the corresponding channel adaptability guide rails 16 are replaced, and the two first screws 21 are tightened to realize the quick switching of the channel adaptability guide rails 16.

[0052] At the chopping knife position 4 of each wire suction channel 3, a second mounting groove recessed upward 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, and a chopping knife adaptability guide rail 23 is respectively detachably installed in the second mounting grooves at the bottom of the end guide rail body 1 and the middle guide rail body 2, and the channel between the two chopping knife adaptability guide rails 23 constitutes the lower section of the chopping knife position 4 of the wire suction channel 3, and 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.

[0053] The splitting knife adaptability guide rail 23 is L-shaped as a whole, and the horizontal section of the splitting knife adaptability guide rail 23 is attached to the bottom surface of the second mounting groove and is detachably connected with the corresponding guide rail body. In this embodiment, the horizontal section of the splitting knife adaptability guide rail 23 is detachably connected with the end guide rail body 1 or the inner section of the middle guide rail body 2 by screw connection, that is, two second screws 24 are respectively passed upward through the two second mounting holes 25 of the splitting knife adaptability guide rail 23 and then tightened in the threaded holes on the corresponding second mounting groove. The channel between the vertical sections of the two splitting knife adaptability guide rails 23 constitutes the lower section of the wire suction channel 3.

[0054] According to the different specifications of cigarettes to be produced, a plurality of chopper adaptability rails 23 of different specifications can be designed to meet the high-quality trimming requirements of cigarettes of different specifications. When switching between chopper adaptability rails 23 of different specifications, the two second screws 24 are unscrewed, the corresponding chopper adaptability rails 23 are replaced, and the two second screws 24 are tightened to realize the quick switching of the chopper adaptability rails 23.

[0055] At the splitting position 4 of each wire suction channel 3, the side wall of the channel adaptability guide rail 16 away from the splitting position 4 of the wire suction channel 3 is called the adjacent channel side wall, and the upper section of the adjacent channel side wall of the channel adaptability guide rail 16 is provided with a wire suction belt installation groove 26 extending forward and backward, and the height distance between the bottom surface of the channel adaptability guide rail body 18 and the bottom surface of the wire suction belt installation groove 26 of the adjacent channel side wall is called the adjacent channel matching height distance;

[0056] The two wire suction channels 3 are respectively the first wire suction channel and the second wire suction channel. The tobacco conveying direction of the two wire suction channels 3 is from back to front. The chopping knife position 4 of the first wire suction channel is located behind the chopping knife position 4 of the second wire suction channel. The adjacent channel matching height distance of the channel adaptability guide rail 16 at the chopping knife position 4 of the first wire suction channel is the first adjacent channel matching height distance H1, and the adjacent channel matching height distance of the channel adaptability guide rail 16 at the chopping knife position 4 of the second wire suction channel is the second adjacent channel matching height distance H2. The first adjacent channel matching height distance H1 is calculated by formula 2, and the second adjacent channel matching height distance H2 is calculated by formula 3. The height distance of the vertical section of the chopping knife adaptability guide rail 23 at the position above the chopping knife disk 6 is the chopping knife matching height H3, and the chopping knife matching height H3 is calculated by formula 4:

[0057] H1=[(x / z)×d+3]×1.3 2

[0058] H2=[(x / z)×d+3]×1.1 3

[0059] H3=(x / z)×d-1.5 4

[0060] Among them, x is the filling value of the produced tobacco, z is the inherent filling value of the produced tobacco 4.6, and d is the diameter of the produced cigarette.

[0061] When the equipment is working normally, a suction belt is attached to each ceramic bead 8 in the suction channel 3, and the suction belt slides against the roller surface of the ceramic bead 8. Under the action of negative pressure suction, the tobacco is adsorbed on the suction belt and clamped by the side surfaces of the guide rails on both sides of the suction channel 3 and transported from back to front. When the tobacco bundle is transported to the chopping position 4, the chopping device 5 is started, and the lower section of the tobacco bundle is trimmed by two counter-rotating chopping discs 6, and the trimmed tobacco bundle continues to be transported forward in the suction channel 3.

[0062] When it is necessary to switch the specifications of the produced cigarettes, first calculate the calibration height H of the cigarettes of this specification by the above formula 1, and then increase or decrease the number of adjustment pieces 10 at the bottom of the calibration guide rail 9, so that the calibration height H of the calibration device reaches the calibration height value corresponding to the cigarettes of this specification. The equipment is shut down, the suction belt is disassembled, and the calibration guide rail 9 is placed from the bottom to the top in the suction channel 3 from the chopping position 4 of the suction channel 3 until the top surface of the calibration guide rail 9 fits with the porcelain beads 8, and at the same time, the two limit columns 15 are respectively fitted with the front and rear sides of the two front and rear porcelain beads 8 in the suction wire, and then the hanging cover plate 13 is put on the stud 12 of the suction guide rail and the nut 14 is tightened to realize the installation of the calibration device and the suction channel 3. After that, the height position of the two chopping discs 6 of the chopping device 5 is adjusted until the distance between the top of the trimming part 7 of the two chopping discs 6 and the bottom of the lowest adjustment piece of the calibration guide rail 9 reaches a constant value. In this embodiment, the constant value is 0.3mm. The distance between the top of the trimming part 7 of the two riving blade discs 6 and the bottom of the lowest adjustment piece of the calibration guide rail 9 can be measured by a feeler gauge with a thickness of 0.3 mm. The distance between the top of the trimming part 7 of the two riving blade discs 6 and the bottom of the lowest adjustment piece of the calibration guide rail 9 is called a constant distance.

[0063] In the process of adjusting the height position of the two cleaving blade discs 6 of the cleaving blade device 5, when it is found that the channel adaptability guide rail 16 interferes with the cleaving blade disc 6, the channel adaptability guide rail 16 of appropriate specifications can be switched first, and then the height position of the two cleaving blade discs 6 can be adjusted until the two cleaving blade discs 6 reach the specified height position. After adjusting the height position of the cleaving blade disc 6, two cleaving blade 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 cleaving blade adaptability guide rails 23 is just flush with the bottom of the lowest adjustment plate of the calibration guide rail 9, that is, the adjustment of the appropriate height position of the two cleaving blade discs 6 is completed. After adjustment, the calibration height H of the calibration device plus the constant spacing of 0.3mm is the height of the tobacco bundle trimmed by the cleaving blade 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.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
