Description
Technical Field
The invention belongs to the technical field of cigarette equipment, and particularly relates to a design method of an asynchronous gluing system of a cigarette making and tipping unit.
Background
The cigarette rolling and splicing quality not only represents the attitude of a production enterprise for quality treatment, but also reflects the technical level of equipment maintenance, and the cigarette rolling and splicing quality is the most frequent quality defect. Along with the relative requirements of the individualized design of the product appearance on the tipping paper, the problem that some tipping paper is not easy to glue is gradually shown, the poor gluing of the tipping paper is the primary and key factor for determining the cigarette twisting quality, and once the gluing of the tipping paper is poor, the quality problems of the tipping paper, such as wrinkles, uneven lap joint, flash, air leakage and even mouth dropping, are easily caused.
The tipping paper is rubberized in two modes, one mode is synchronous rubberizing, the rotating linear speed of a glue spreader of the rubberizing mode is the same as the running speed of the tipping paper, and the rubberizing work is mainly completed by printing glue on the tipping paper; the other gluing mode is asynchronous gluing, the rotating linear speed of a glue spreader of the gluing mode is higher than the running speed of the tipping paper, glue is finally coated on the tipping paper to finish gluing, and the situation that no glue, less glue and the like exist on the tipping paper due to the factors of manufacturing precision and abrasion of the glue spreader, difficulty in gluing certain tipping paper, insufficient gluing on partial positions of the tipping paper and the like is avoided, and the cigarette twisting quality problem can be directly generated due to no glue and less glue on the tipping paper. The gluing process of the tipping paper is shown in figure 1, the glue control roller 13 takes out a proper amount of glue from the glue pool 14 and transfers the glue to the glue spreader 12, and the glue spreader 12 rotates to print or paint the glue on the surface of the glue on the running tipping paper 11.
The synchronous gluing system is generally adopted in China, and in order to solve the problem of twisting and splicing quality of certain tipping paper caused by factors such as manufacturing precision of a glue spreader, abrasion, difficulty in gluing of the certain tipping paper, insufficient gluing of partial positions of the tipping paper and the like, few parts of cigarette making and splicing units adopt the asynchronous gluing system designed by the original machine.
The drive scheme of the tipping paper gluing system of the cigarette making machine set is shown in figure 2. The working principle of the synchronous gluing system is as follows: when the machine is normally produced, the main transmission gear 17 transmits the power of the main transmission of the whole machine to the transmission gear 18, the gluing roller shaft on which the transmission gear 18 is installed rotates, the linear speed of the surface of the gluing roller 12 is consistent with the speed of the tipping paper through a reasonable design transmission ratio, the rotation of the gluing roller shaft drives the gluing roller gear 15 installed on the gluing roller shaft to rotate, the power is transmitted to the glue control roller gear 16 through the gluing roller gear 15, so that the glue control roller 13 is driven to rotate, the glue in the glue pool is properly taken out by the glue control roller 13 and is transmitted to the gluing roller 12, and the gluing roller 12 synchronously prints the glue on the tipping paper.
The asynchronous gluing system has the same working principle as the synchronous gluing system, and the rotation linear speed of the gluing roller is required to be higher than the running speed of the tipping paper, so that in order to ensure the realization of the function, the synchronous gluing system is changed into the asynchronous gluing system in the prior art, the synchronous gluing system is usually realized by changing the number of teeth of a transmission gear and the diameter of the gluing roller, but the diameter of a glue control roller, a gear of the glue control roller and the number of teeth of the gluing roller are also changed.
Meanwhile, the asynchronous proportion (namely the ratio of the linear speed of the glue spreader to the running speed of the tipping paper) of an asynchronous gluing system designed by the original machine is fixed, and the gluing method is not necessarily suitable for gluing the tipping paper of the required brand of cigarettes. Moreover, because the transmission gear is positioned in the gear box of the main machine and is inconvenient to replace, the gear is time-consuming and labor-consuming when a synchronous gluing system and an asynchronous gluing system are switched or only the gear of the asynchronous gluing system is replaced aiming at tipping paper of different brands or tipping paper sheets with different lengths.

In order to achieve the purpose, the invention provides the following technical scheme:

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description will be provided with reference to specific embodiments.
As shown in fig. 3, an embodiment of the present invention provides a method for designing an asynchronous gluing system of a cigarette making and tipping unit, which includes the following steps:
s1, designing an asynchronous proportion of an asynchronous gluing system according to tipping paper of different brands, wherein the asynchronous proportion refers to a ratio of a linear speed of a glue spreader to a running speed of the tipping paper;
s2, calculating the diameter of the glue spreader according to the asynchronous proportion;
s3, under the conditions that the linear speeds of the glue control roller and the glue spreader are equal and the gear transmission is stable and accurate, the diameter of the glue control roller, the number and the modulus of teeth of the glue spreader roller and the number and the modulus of teeth of the glue control roller are designed under the limitation of an installation space;
s4, mounting the designed glue spreading roller, the designed glue control roller, the designed glue spreading roller gear and the designed glue control roller gear to the original positions of all the parts on the original machine.
According to the method for designing the asynchronous gluing system of the cigarette making and tipping unit, provided by the embodiment of the invention, a glue spreading roller, a glue control roller, a glue spreading roller gear and a glue control roller gear which are matched with tipping paper can be quickly designed according to the tipping paper of different brands, so that the asynchronous gluing system matched with the tipping paper is obtained; meanwhile, related gears in the main gear box which is inconvenient to disassemble do not need to be replaced, and only executing parts which are convenient to disassemble, clean and maintain, namely the glue coating roller, the glue control roller, the glue coating roller gear and the glue control roller gear, need to be replaced, so that the asynchronous glue coating system is convenient and rapid to disassemble, assemble and replace, time and labor are saved, and the operation efficiency is effectively improved. Moreover, the switching between the synchronous gluing system and the asynchronous gluing system can be time-saving and labor-saving.
It can be understood that the rubber control roller and the glue coating roller roll relatively, and the linear speeds of the rubber control roller and the glue coating roller are equal, so that abrasion and heating can be well avoided; the linear speed of the glue control roller is determined by the diameter of the glue coating roller, the gear of the glue control roller and the diameter of the glue control roller.
The asynchronous proportion of the asynchronous gluing system is not fixed, but can be flexibly designed. During design, a plurality of asynchronous proportions can be flexibly designed, and the gluing quality of tipping paper in an asynchronous gluing system is compared under each asynchronous proportion; and then, selecting the asynchronous proportion corresponding to the asynchronous gluing system with the best gluing quality of the tipping paper as the asynchronous proportion which is most matched with the tipping paper, namely the optimal asynchronous proportion, wherein the corresponding asynchronous gluing system is the asynchronous gluing system which is most matched with the tipping paper at the moment so as to improve the gluing quality of the tipping paper, thereby improving the cigarette twisting quality and reducing the waste consumption.
In particular, different brands of tipping paper have tipping paper sheets of different length specifications.
Further, the basis for the smooth and accurate gear transmission is as follows: the center distance between the glue control roller and the glue coating roller is equal to the installation center distance between the glue control roller gear and the glue coating roller gear.
In particular, when the diameter of the glue spreader is large, part of the material is removed from the core of the glue spreader, so that the excessive load of the glue spreader shaft can be well avoided.
In order to ensure that tipping paper of different brands has a good gluing effect, an asynchronous gluing system matched with the tipping paper needs to be designed, and the asynchronous gluing system needs to adopt different rotation speeds and diameters of glue rollers according to different gluing performances of the tipping paper, namely, the ratio of the linear speed of the glue roller of the asynchronous gluing system to the running speed of the tipping paper needs to be variable. In addition, when different tipping papers are used, different gluing systems need to be designed and replaced, and the design of the asynchronous gluing system does not need to change gears in a main transmission gear box of the main machine, because the aim of asynchronous gluing is to finally ensure that the linear speed of the glue spreader is slightly greater than the running speed of the tipping papers, the assembled cigarette making and tipping machine set after purchase is not suitable for disassembling and replacing parts of an internal gear box, time, labor and money are wasted, and the originally matched precision can be damaged.
As shown in figure 4, the invention only designs and improves the executive parts which are required to be frequently disassembled, cleaned and maintained outside under the condition of ensuring that a transmission system and parts in the machine are not changed, namely only changing the diameters of the gluing roller gear 21, the gluing roller 23 and the glue control roller gear 22 and the glue control roller 24 to form a set of independent asynchronous gluing system, if the synchronous gluing system needs to be replaced, only the original parts need to be installed, the operation is very convenient and efficient, even auxiliary parts such as the glue cylinder 25 do not need to be changed, and therefore, the asynchronous gluing system is more convenient and quicker to disassemble and replace. The invention provides a simple, efficient and practical design method for the asynchronous gluing system, and because a plurality of cigarette brands are available and the specifications of the circumferences of cigarettes of various brands are different, a size can not be designed to meet the requirements of cigarettes of all brands, the tooth number of the gluing roller gear 21, the diameter of the gluing roller 23, the tooth number of the glue control roller gear 22 and the diameter of the glue control roller 24 need to be changed, and the motions of the four parts need to be matched, namely the gear transmission needs to be stable and accurate, and the linear speeds of the glue control roller and the gluing roller need to be equal.
As shown in fig. 4 to 8, in a specific embodiment provided by the present invention, when a certain brand of tipping paper is used, for example, the length specification of a tipping paper sheet is 27mm, the tipping paper is not well sized by using the synchronous sizing system of the original machine, and the asynchronous sizing system is considered, the designed asynchronous ratio is 1.08, that is, the linear speed of the glue spreader is 1.08 times the running speed of the tipping paper, so the diameter of the glue spreader 23 is 74mm, it can be understood that the diameter of the glue spreader is equal to the asynchronous ratio multiplied by the diameter of the glue spreader roller in the synchronous sizing system; due to the large diameter of the 74mm applicator roll, the core of the applicator roll 23 is partially stripped of material, as shown in figure 5, taking into account the heavy load on the applicator roll shaft. Considering that the glue control roller 24 and the glue spreader roll relatively, in order to avoid abrasion and heating, the linear velocities of the glue control roller 24 and the glue spreader 23 are required to be consistent, and the linear velocity of the glue control roller 24 is determined by the diameter of the glue spreader, the diameter of a glue spreading roller gear, a glue control roller gear and the diameter of the glue control roller, and in addition, in order to ensure stable and accurate transmission, the central distance of the two rollers is required to be equal to the installation central distance of the two gears, and finally, the diameter of the glue control roller, the glue spreading roller gear 21 and the glue control roller gear 22 are designed under the limitation of installation space, namely, the diameter of the glue control roller 24 of a gluing asynchronous system matched with the tipping paper is designed to be 74mm, the number of teeth of the glue spreading roller gear 21 is 37, and the modulus is 2, it can be understood that the diameter of the pitch circle of the glue spreading roller gear is equal to the diameter of the glue spreading roller, and the numerical value obtained by multiplying the number of teeth of the gear by the modulus is equal to the diameter of the pitch circle of the glue spreading roller gear; the tooth number of the rubber control roller gear is 37, and the modulus is 2. Aiming at the tipping paper of different brands, the design of the asynchronous gluing system can be carried out according to the method, so that the design and the replacement of the asynchronous gluing system are quick and convenient, the gluing effect of the tipping paper is improved, and the cigarette twisting quality risk is reduced.
The above are only preferred embodiments of the present invention, it should be noted that these examples are only for illustrating the present invention and not for limiting the scope of the present invention, and after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalents also fall within the scope of the claims appended to the present application.
