Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, in particular to a trademark paper conveying module of a packaging machine. Background Art

[0002] The ZB45 hard pack packaging machine is used by domestic cigarette manufacturers to produce hard pack cigarettes. With a production capacity of 400 packs per minute, it boasts a compact structure and reliable quality, making it a mainstream medium-speed packaging machine in China. Its stable and reliable operation, simple operation, and easy maintenance have earned it widespread use in the tobacco industry.

[0003] The main unit of the ZB45 packaging unit, the YB45 small box packaging machine, has its label paper transverse conveying module fixed on the conveyor belt. It positions and constrains the label paper during its forward conveyance, ensuring that the label paper is transported to the next process in an orderly and accurate manner, thereby ensuring product packaging quality.

[0004] When the equipment is operating, the label paper is trapped between two conveyor modules mounted on the conveyor belt. The conveyor modules carry the label paper to the right along with the conveyor modules. A total of 28 conveyor modules are installed on the entire conveyor belt. To reduce the load on the conveyor belt and ensure equipment safety, the original machine design used plastic conveyor modules. This significantly reduces the load on the conveyor belt and increases its service life. Furthermore, when the equipment becomes jammed, the conveyor modules act as a weak link, protecting other equipment components from damage. However, plastic conveyor modules exhibit poor wear resistance during use, with an average lifespan of three months. If not promptly replaced, severe wear on both sides of the conveyor modules can cause the label paper to become blocked when it is lifted from the transverse conveyor to the longitudinal channel, leading to a failure in the label paper conveying process and a shutdown.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example

[0029] Combined with attachment Figure 1-6As shown, a packaging machine trademark paper conveying module 1 includes: a conveying module main body 11 made of plastic material, and a first wear-resistant block 3, a second wear-resistant block 4 and a third wear-resistant block 5 made of metal material are embedded in the front and rear sides of the conveying module main body 11 from left to right, and the first wear-resistant block 3, the second wear-resistant block 4 and the third wear-resistant block 5 are symmetrical on the front and rear sides, so that the first wear-resistant block 3, the second wear-resistant block 4 and the third wear-resistant block 5 can strengthen the parts of the front and rear sides of the conveying module main body 11 that are in contact with the trademark paper by the first wear-resistant block 3, the second wear-resistant block 4 and the third wear-resistant block 5 to ensure the overall strength of the conveying module.

[0030] Specifically, the conveying module body 11 is formed with a first protrusion 12, a second protrusion 13 and a third protrusion 14 from left to right downward, wherein the first protrusion 12 cooperates with the guide rail 6 of the packaging machine, the second protrusion 13 and the third protrusion 14 respectively cooperate with the mounting seat 8 on the conveyor belt 7 of the packaging machine, the first wear-resistant block 3, the second wear-resistant block 4 and the third wear-resistant block 5 are respectively arranged on the front and rear sides of the first protrusion 12, the second protrusion 13 and the third protrusion 14, and the second wear-resistant block 4 and the third wear-resistant block 5 have the same shape and structure, and are similar to the shape and structure of the first wear-resistant block 3, and are all dovetail structures.

[0031] A first process groove 15 is formed between the first and second raised portions. Mounting stop grooves 16 are formed in the middle of both the second and third raised portions. Each of these grooves contains mounting holes 17, through which bolts or screws, etc., are inserted to attach the conveyor module to the conveyor belt. A second process groove 18 is formed between the second and third raised portions. A circular arc-shaped notch is formed at the rear end of this groove to reduce the mass of the entire conveyor module.

[0032] A further technical solution is to linearly distribute the wear areas of the conveyor module 1 and the label paper 2 at a distance of 6 to 7 mm from the lower mounting surface of the conveyor module. Wear marks are present on both surfaces in contact with the label paper, extending the life of the conveyor module simply by improving the wear resistance of the worn areas. Preferably, the second and third wear-resistant blocks are set to a height of no less than 7 mm to completely cover the worn areas of the conveyor module and the label paper.

[0033] Preferably, the first wear-resistant block, the second wear-resistant block and the third wear-resistant block are all isosceles trapezoids, with the bevel angles of both sides being 45 degrees, and the height of the inner and outer sides being not less than 5 mm. The front and rear thickness of the first wear-resistant block, the second wear-resistant block and the third wear-resistant block is 2.5 mm.

[0034] There is a slope formed on the upper left side of the conveying module. During the process of conveying the trademark paper, the packaging machine needs to fold the trademark paper cover in the conveying module. A guide rail is provided at the front end of this slope. The slope is mainly to facilitate the operation and installation of the guide rail. It is a structure of the original design and will not be explained here.

[0035] In this embodiment, semi-open dovetail grooves are formed on the front and rear sides of the first, second, and third raised portions, respectively, to facilitate quick and easy installation of the first, second, and third wear-resistant blocks. Furthermore, the dovetail grooves of the conveyor module are semi-open. When the label paper enters the conveyor module vertically from the label paper magazine, the contact material between the label paper and the conveyor module is made of plastic, which promotes consistent wear on the upper portion of the label paper when in contact with the conveyor module, protecting the label paper's quality and preventing scratches.

[0036] Preferably, the first, second, and third wear-resistant blocks are all made of 40Cr steel, which has good comprehensive mechanical properties, a hardness of 174 to 299HB, and good wear resistance. The service life of the conveying module embedded with the wear-resistant blocks is increased by 6 times, which greatly improves the service life of the conveying module, reduces the labor intensity of maintenance personnel, improves equipment reliability, and saves spare parts costs for the factory. Each wear-resistant block is embedded in three stages, and the difference in mass with the original conveying module is only 5 grams, which has little impact on the belt; at the same time, the segmented embedding allows the conveying module as a whole to maintain the mechanical properties of the original conveying module without being affected, which can effectively ensure the safety of the equipment.

[0037] In order to further ensure the installation strength of the wear-resistant blocks, preferably, the wear-resistant blocks are also bonded with electric welding glue, which can maintain a good bonding effect and prevent the wear-resistant blocks from shaking in the conveying module. The overall installation is firm and reliable, ensuring noiseless operation.

[0038] Since the contact position between the conveying module of the trademark paper transverse conveying channel of the YB45 small box packaging machine and the edge of the trademark paper is fixed, the design takes into account the wear-resistant treatment of the worn parts, abandons the design of using engineering plastics as a whole, and inlays the wear parts with wear-resistant materials to solve the problems of easy wear and short service life of the conveying module. The inlay method adopts a dovetail groove with a narrow outside and a wide inside, so that the wear-resistant material can be well embedded in the conveying module. Its overall size is consistent with the original conveying module.

[0039] The inlaid design is adopted. Wear-resistant strengthening treatment is performed on the original conveying module according to the wear parts of the conveying module, which improves the wear resistance of the conveying module, extends the service life of the conveying module, improves equipment reliability, and reduces spare parts consumption and maintenance workload.

[0040] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
