Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, in particular to a splitter for a feeding strip-forming machine. Background Art

[0002] The YJ17 feeder and stripper is a key component of the YJ17 cigarette making unit. The feeding system provides raw tobacco to the machine, loosening and evenly dispersing it, removing iron and impurities, before conveying it to the stem and cut tobacco separation system. The stem and cut tobacco separation system separates the tobacco from the feeder into stems and cut tobacco, then delivers the uniform tobacco to the suction duct of the tobacco forming system. The separated stems and impurities are then conveyed to a secondary sorting device for secondary separation. The tobacco forming system absorbs the uniform, impurity-free, and stem-free tobacco from the stem and cut tobacco separation system onto the suction belt, forming a uniform tobacco bundle. After being trimmed by the inner and outer chopping discs of the leveler, tobacco strips with uniform weight and tight ends are conveyed to the tobacco gun of the YJ17 cigarette making machine's rolling and forming unit for rolling.

[0003] The cigarette weight control system trims the tobacco strands formed by the suction and forming system to control cigarette weight. According to the process requirements: 1. Trimming by the inner and outer splitting discs of the leveler results in a tobacco strand with uniform weight and a tight end. 2. To ensure the fullness of the cigarette end, the slicing position of cigarettes with tight ends is within ±2.0mm after instrument testing. 3. The amount of tobacco strands at the end of the cigarette is less than 8mg per cigarette after instrument testing.

[0004] See Figure 1 The feeder blade includes a blade body 100 with downwardly protruding blade grooves 200 uniformly formed along its circumference. Prior to the improvement, the blade was made of thin manganese steel sheet. To prevent tearing during the stamping process, the inner edge 300 (inner edge) of the blade groove 200 was designed as a straight edge, and the two side surfaces 500 were also vertical surfaces with straight edges. Because the outer edge 400 of the blade groove is a circular arc and the inner edge 300 is a straight edge, the center of the blade groove, i.e., the highest point 401 (outermost point) of the outer edge of the blade groove, has the largest unit area.

[0005] Demonstration shows that a splitter punched from manganese steel sheet achieves maximum tobacco plumpness at the cigarette end only when the blade cuts at the center of the splitter groove (slicing position 0). When the slicer position is not 0, the tobacco plumpness of the cigarette end decreases. The further away from the center, the greater the decrease in plumpness, and the more tobacco dropout occurs at the end. This directly results in a hollow cigarette end and a high rate of rejects. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model develops a splitter for a feeding strip forming machine to solve the problem that when the close slicing position of the cigarette end face is not in the exact center, the filling fullness of the tobacco shreds on the cigarette end face is consistent with that when the slicing position is in the exact center, thereby solving the problems of excessive tobacco shreds on the cigarette end face, empty cigarette end faces and a large amount of waste rejection.

[0007] The technical solution of this utility model to solve the technical problem is:

[0008] The present application provides a cleaver for a material feeding and strip forming machine, comprising a cleaver body, wherein the cleaver body is uniformly provided with downwardly protruding cleaver grooves along the circumferential direction, wherein the cleaver grooves are provided on the edge of the cleaver body, and wherein the cleaver grooves include a bottom surface, an inner arc surface, and an inclined side surface, wherein the bottom surface is arranged parallel to and below the blade surface of the cleaver body, the inner arc surface is vertically connected between the inner edge of the bottom surface and the blade surface of the cleaver body, the upper edge of the inclined side surface is connected to the blade surface of the cleaver body, the lower edge of the inclined side surface is respectively connected to the left and right ends of the bottom surface, and the inner edge of the inclined side surface is respectively connected to the left and right ends of the inner arc surface;

[0009] The inner edge of the bottom surface is an inner arc, the outer edge of the bottom surface is an outer arc, the inner arc and the outer arc are concentric arcs, and the inclined side surface is inclined upward.

[0010] As an improvement to the above solution, the riving knife body is made of stainless steel.

[0011] As an improvement to the above solution, the number of the riving knife grooves is 6.

[0012] Compared with the prior art, the above solution has the following advantages or beneficial effects:

[0013] The utility model provides a splitter for a feeding strip forming machine, wherein the inner and outer edges of a splitter groove are arranged to be concentric arcs, so as to ensure that when the slicer cutting position is not 0, the filling fullness of tobacco shreds on the end face of a cigarette is the same as when the slicer cutting position is 0; in addition, the two inclined side surfaces of the splitter groove are arranged inclined, so as to avoid the phenomenon of tobacco shreds falling off the cigarette due to a sudden reduction of tobacco shreds.

[0022] See Figure 2-5This embodiment provides a cleaver for a feeding strip forming machine, comprising a cleaver body 1, the cleaver body 1 being provided with 6 downwardly protruding cleaver grooves 2 evenly arranged along the circumferential direction, and the cleaver grooves 2 being provided at the edge of the cleaver body 1. Figure 3 The cleaver groove 2 is composed of four surfaces, namely a bottom surface 3, an inner arc surface 4 and two inclined side surfaces 5. The bottom surface 3 is arranged parallel to the lower side of the blade surface 11 of the cleaver body. The inner arc surface 4 is vertically connected between the inner edge of the bottom surface 3 and the blade surface 11 of the cleaver body. The upper edge of the inclined side surface 5 is connected to the blade surface 11 of the cleaver body. The lower edge of the inclined side surface 5 is respectively connected to the left and right ends of the bottom surface 3, and the inner edges of the two inclined side surfaces 5 are respectively connected to the left and right ends of the inner arc surface 4.

[0023] The inner edge of the bottom surface 3 is an inner arc 31, and the outer edge of the bottom surface 3 is an outer arc 32. The inner arc 31 and the outer arc 32 are concentric arcs, ensuring that when the slicer cutting position is not 0, the filling fullness of the tobacco at the end of the cigarette is the same as when it is 0, that is, providing a more uniform contact surface and ensuring the continuity of the cutting path. This means that no matter where the splitter body 1 cuts, the cutting method of the tobacco remains consistent, which helps to maintain the overall shape and density of the tobacco, thereby ensuring full filling while reducing tobacco waste.

[0024] The inclined side surface 5 is tilted upward. In the prior art, the vertical surface may suddenly reduce the tobacco. However, the inclined side surface 5 allows the tobacco to gradually reduce, thus avoiding the phenomenon of tobacco falling off the cigarettes due to the sudden reduction of tobacco.

[0025] The cutting blade of the feeding strip forming machine is made of stainless steel by mechanical washing, instead of the existing method of stamping manganese steel sheet, which avoids the material tearing phenomenon caused by complex shape and compact size that affects the quality of cut tobacco.

[0026] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the utility model.
