Description

Technical Field

[0001] The utility model relates to the technical field of cigarette-making equipment, and particularly relates to a No. 6 wheel of a packaging machine. Background Art

[0002] During the operation of the ZB45 packaging machine, the trademark paper is first picked up from the paper magazine, horizontally and longitudinally conveyed, coated with glue, and then reaches the lower left of the No. 5 wheel. Then it is sent to directly below the No. 5 wheel by the trademark paper horizontal conveyor and enters the No. 5 wheel packaging wheel together with the aluminum foil paper and the inner frame paper. The formed cigarette pack enters the No. 6 wheel from the No. 5 wheel and rotates intermittently in the clockwise direction, then enters the No. 7 wheel for drying, and is then output by the No. 8 wheel and enters the output channel.

[0003] After analyzing and observing the reasons for scratches on the surface of the trademark paper, it is found that there are very few scratches generated before the No. 5 wheel. During the production process, it is found that the scratches on the cigarette pack are generated by the No. 6 wheel.

[0004] The No. 6 wheel is a formed cigarette pack conveying wheel that is horizontally placed and rotates intermittently in the clockwise direction, making a circular motion. The formed cigarette pack makes a transition as it rotates with the No. 6 wheel, and the unqualified cigarette packs are removed on this wheel by the rejection device. The pressure exerted by the No. 6 wheel box mold pawl on the cigarette pack is controlled by the springs on both sides of the pawl. The pawl generates friction with the cigarette pack under the action of the pressure. The greater the pressure, the greater the friction generated, resulting in scratches at both ends of the cigarette pack. Under the action of centrifugal force, the spring hook installed on the mold box becomes loose and loses effective control, unable to hold the cigarette pack, causing the cigarette pack to move outwards and contact the No. 6 wheel baffle. The material of the baffle is relatively hard, generating a certain amount of friction, thus causing scratches on the back of the cigarette pack. Content of the Utility Model [[ID=I8]]

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the scratches on the cigarette pack generated by the No. 6 wheel in the prior art during the production process.

[0006] To solve the above technical problem, the utility model provides a No. 6 wheel of a packaging machine, which includes a rotary tower and No. 6 wheel mold boxes evenly arranged circumferentially in the rotary tower;

[0007] The rotary tower includes a first cover plate and a second cover plate arranged parallel to each other up and down. The No. 6 wheel mold boxes are located between the first cover plate and the second cover plate. Anti-friction protection sheets and baffles are sequentially pasted on the edges of the first cover plate and the second cover plate;

[0008] The No. 6 wheel mold box includes a mold box body. Pawls are rotatably connected to both sides of the mold box body. The pawls control the clamping and releasing of the cigarette pack through springs, and the wire diameter of the springs is reduced to reduce the friction force when the pawls clamp the cigarette pack.

[0009] As an improvement to the above solution, the friction coefficient of the anti-friction protection sheet is lower than that of the retaining sheet.

[0010] As an improvement to the above solution, the anti-friction protection sheet is made of polytetrafluoroethylene material, and the retaining sheet is made of steel material.

[0011] As an improvement to the above solution, the wire diameter of the spring is reduced from 0.4 mm to 0.3 mm.

[0012] The technical solution of the present utility model has the following advantages:

[0013] The present utility model provides a No. 6 wheel of a packaging machine. By arranging an anti-friction protection sheet with a lower friction coefficient at the edges of the first cover plate and the second cover plate, the friction force on the back of the cigarette pack is reduced. Also, by using a spring with a smaller diameter, the friction force generated by the pawl on both sides of the cigarette pack is reduced, thereby avoiding scratches at both ends of the cigarette pack. The structure of this application is simple, easy to maintain, and has a long service life, solving the problem of scratches on the surface of the cigarette pack caused by the No. 6 wheel.

[0017] The following will clearly and completely describe the technical solutions of the present utility model in conjunction with the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0018] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] As Figure 1 shown is a specific embodiment of the sixth wheel of the packaging machine provided by the present utility model. A sixth wheel of a packaging machine includes a rotary tower 1 and six-wheel die boxes circumferentially and evenly arranged in the rotary tower 1.

[0022] The above-mentioned rotary tower 1 includes a circular first cover plate 11 and a second cover plate 12 arranged parallel up and down. The six-wheel die boxes are located between the first cover plate 11 and the second cover plate 12 and are circumferentially and evenly distributed with 8. The six-wheel die boxes make intermittent circular motions along with the rotary tower 1.

[0023] Anti-friction protection sheets 3 are pasted on the edges of the above-mentioned first cover plate 11 and second cover plate 12. A retaining piece 2 is pasted on the outer side of the anti-friction protection sheet 3. The friction coefficient of the anti-friction protection sheet 3 is lower than that of the retaining piece 2. Specifically, the anti-friction protection sheet 3 is made of polytetrafluoroethylene material, and the retaining piece 2 is made of steel material. The friction coefficient of the polytetrafluoroethylene material is much lower than that of the steel material. When the cigarette pack moves outward under the action of centrifugal force and contacts the anti-friction protection sheet 3, since the friction coefficient of the anti-friction protection sheet 3 is small, the frictional force generated on the cigarette pack is small and it is not easy to scratch the outer surface of the cigarette pack.

[0024] The above-mentioned No. 6 wheel die box includes a die box body 5. Pawls 6 are rotatably connected to both sides of the die box body 5. A spring 4 is arranged outside the pawls 6. The pawls 6 clamp and release cigarette packs through the compression and rebound of the spring 4. When a cigarette pack is pushed towards the die box body 5, the spring 4 will be compressed and store energy. When the cigarette pack reaches the end of the die box body 5, the spring 4 will release the stored energy and push the pawl 6 back to its original position to prepare to contact the next cigarette pack again.

[0025] The elasticity of the above-mentioned spring 4 is directly proportional to the rigidity modulus (material) and wire diameter of the wire material of the spring 4, and inversely proportional to the total number of turns (actually the effective number of turns) and the mean diameter of the spring 4. The elasticity of the spring 4 can be changed by changing the material of the spring 4, the wire diameter of the spring 4, the total number of turns of the spring 4, and the mean diameter. In this embodiment, on the basis of not changing the material of the spring 4, the total number of turns of the spring 4, and the mean diameter, only changing the wire diameter of the spring 4 to reduce the elasticity of the spring 4 is the most direct and easy-to-implement method. The wire diameter of the spring 4 controlling the pawl 6 is reduced from 0.4 mm to 0.3 mm, and the wire diameter of the spring 4 is reduced by 0.1 mm compared with before, thereby reducing the frictional force generated by the pawl 6 on the cigarette pack under pressure and reducing the scratches on the cigarette pack by the pawl 6.

[0026] Obviously, the above-mentioned embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the present utility model.
