Description

TECHNICAL FIELD

[0001] The utility model relates to cigarette equipment technical field especially relates to a packing machine aluminium foil paper conveying device. BACKGROUND

[0002] In the production process of the tobacco industry, the stable operation of the packing machine is crucial to production efficiency and product quality. Taking the YB45A type slim packing machine as an example, in actual production, the aluminum foil paper deviation fault is more prominent, which accounts for about 30% of the total downtime. This fault not only seriously affects the normal operation of the equipment, but also causes a large amount of consumption of raw and auxiliary materials, and significantly increases the labor intensity of the operators and maintenance personnel.

[0003] Referring to Figure 1 , the existing packing machine aluminum foil paper conveying device includes a driving shaft and an acceleration roller, the acceleration roller includes a driving roller 100 and a driven roller 200, the driving roller 100 is driven by gear meshing with the driving shaft, and the driving roller 100 and the driven roller 200 are also driven by a pair of gears meshing, and the aluminum foil paper is clamped between the shaft shoulders 300 of the driving roller 100 and the driven roller 200.

[0004] In-depth analysis of the causes of aluminum foil paper conveying deviation mainly includes the following points: first, the aluminum foil paper conveying channel gap is large, and when the aluminum foil paper is continuously released by the acceleration roller of the slim device, the aluminum foil paper is prone to shaking in the conveying channel. Second, there is no effective guidance of the aluminum foil paper from the acceleration roller to the paper positioning reference position, which makes the aluminum foil paper prone to deviation in the conveying process. Especially, in the existing technology, the overlap length of the aluminum foil paper at both ends of the cigarette pack is small, only 8.5mm on each side, when the aluminum foil paper conveying is unstable and deviates, the second wheel will trigger the deviation detection, which will cause the equipment to alarm and stop, and the unqualified cigarette pack will be removed at the third wheel removal position.

[0005] In summary, the existing packing machine aluminum foil paper conveying system has many problems, and there is an urgent need for a new technical solution to solve the problems of aluminum foil paper conveying skew and deviation. INVENTION CONTENTS

[0006] The utility model aims at the shortage of prior art, and develops a packing machine aluminum foil paper conveying device, which improves the straightness of the aluminum foil paper and ensures that the aluminum foil paper can be stably conveyed between the driving roller and the driven roller.

[0007] The technical scheme for solving the technical problem of the utility model is:

[0008] The application provides a packaging machine aluminum foil conveying device, which comprises driving rollers and driven rollers arranged in parallel, wherein the driving rollers are provided with guide concave rollers and shaft shoulders I at intervals, the circumferential direction of the shaft shoulders I is provided with grooves at intervals, and the roller surface of the guide concave rollers is concave inward.

[0009] The driven rollers are provided with guide convex rollers and shaft shoulders II at intervals, the shaft shoulders II are provided with flanges matched with the grooves, and the roller surface of the guide convex rollers is convex outward and matched with the guide concave rollers.

[0010] The flanges are located in the grooves, the guide concave rollers and the guide convex rollers are oppositely arranged to form a conveying guide roller pair, and the aluminum foil is clamped between the driving rollers and the driven rollers through the shaft shoulders I and II, the guide concave rollers and the guide convex rollers.

[0011] As an improvement of the above scheme, the packaging machine aluminum foil conveying device further comprises a driving shaft which is integrally connected with the driving roller.

[0012] As an improvement of the above scheme, the driving roller is made of 45# steel, and the outer surface of the shaft shoulder II is coated with polyurethane.

[0013] As an improvement of the above scheme, two shaft shoulders I are arranged on the driving roller at intervals, and one groove is arranged on each shaft shoulder I.

[0014] The number of the shaft shoulder II is one, the number of the flange is two, and the flange corresponds to the position of one groove.

[0015] As an improvement of the above scheme, the one end of the driving roller and the driven roller is respectively sleeved with a gear which is meshed with each other.

[0016] As an improvement of the above scheme, the diameter of the flange is 1.6mm larger than the diameter of the shaft shoulder II, the width of the flange is 2mm, and the width of the groove is 5mm.

[0017] Compared with the prior art, the above scheme has the following advantages or beneficial effects:

[0018] Through the cooperation of the groove on the driving roller and the flange on the driven roller, the function of extruding the aluminum foil is increased while the aluminum foil is rolling and conveying, the deviation of the aluminum foil is limited, and the effect of the surface of the aluminum foil is realized.

[0019] Through the conveying guide roller pair combined with concave and convex, the surface of the aluminum foil can be rolled, which helps the surface of the aluminum foil to be corrugated in the conveying process, increases the stiffness of the surface of the aluminum foil, and eliminates the problems of poor conveying caused by winding and bending of the aluminum foil or quality defects caused by the folding angle.

[0020] In summary, this application provides guidance for the conveying of aluminum foil, improves the straightness of the aluminum foil, and alleviates the problems of bending, wrinkling, and misalignment of the aluminum foil during conveying, enabling the aluminum foil to be conveyed smoothly to the next process.

[0028] See Figures 2-4 This embodiment provides an aluminum foil paper conveying device for a packaging machine, including a drive shaft 3, and a driving roller 1 and a driven roller 2 arranged in parallel.

[0029] The drive roller 1 is provided with guide concave rollers 8 and two shoulders I4 at intervals. Each shoulder I4 has a groove 5 opened in the circumferential direction. The roller surface of the guide concave roller 8 is concave inward.

[0030] The driven roller 2 is provided with a guide convex roller 9 and a shoulder II 6 at intervals. The shoulder II 6 is provided with two flanges 7 that are adapted to the groove 5. The roller surface of the guide convex roller 9 is outwardly protruding and adapted to the guide concave roller 8.

[0031] One end of the driving roller 1 and the driven roller 2 are respectively fitted with meshing gears 10, and the synchronous rotation of the driving roller 1 and the driven roller 2 is realized through the meshing transmission of the gears 10.

[0032] Flange 7 is located within groove 5. Guide concave roller 8 and guide convex roller 9 are arranged opposite each other to form a conveying guide roller pair. Aluminum foil A is sandwiched between drive roller 1 and driven roller 2 via shoulder I 4 and shoulder II 6, guide concave roller 8 and guide convex roller 9. On the one hand, the groove 5 and flange 7 cooperate to press vertical indentations on the surface of aluminum foil A, ensuring the surface of aluminum foil A is stiff and limiting the lateral deviation of aluminum foil A, thus achieving precise guidance of aluminum foil A. On the other hand, the concave and convex conveying guide roller pair makes the surface of aluminum foil A corrugated during the conveying process, increasing the surface stiffness of aluminum foil A and preventing conveying problems caused by rolling or bending of aluminum foil A or quality defects caused by folds.

[0033] The drive shaft 3 is integrated with the drive roller 1. This design helps reduce the frequency of parts replacement. In traditional designs, due to factors such as part size deviations and material deviations, it is often necessary to replace related parts frequently. This not only affects the stability of aluminum foil paper A conveying but also increases the cost and workload of equipment maintenance. The integrated design of the drive shaft and drive roller 1 effectively avoids these problems and improves the stability and reliability of the entire conveying device.

[0034] The drive roller 1 is made of 45# steel, which improves its wear resistance. During the conveying process of aluminum foil A, the drive roller 1 needs to continuously come into contact with and rub against aluminum foil A and other components. The use of 45# steel can effectively extend the service life of the drive roller 1 and reduce equipment failures caused by wear.

[0035] The outer surface of shoulder II6 is covered with polyurethane material, which has good flexibility and elasticity. While ensuring a suitable coefficient of friction with aluminum foil A, it also facilitates the replacement of driven roller 2. This allows driven roller 2 to effectively transport aluminum foil A when working in conjunction with drive roller 1, and also enables convenient and quick replacement when needed, reducing the difficulty and cost of equipment maintenance.

[0036] The diameter of flange 7 is 1.6mm larger than that of shoulder II 6, meaning it is 0.8mm higher on one side. The width of flange 7 is 2mm, and the width of groove 5 is 5mm. When installed in the center, there is a 1.5mm gap on each side to facilitate the indentation effect. In addition, the 1.5mm gap can prevent insufficient clearance caused by differences in left and right installation dimensions, which could lead to compression and damage to the aluminum foil A.

[0037] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
