Description

Technical Field

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

[0002] The YJ17 feeder strip forming machine is an important part of the YJ17 cigarette making unit. The feeding system provides raw tobacco to the machine, and transports it to the stem separation system after loosening and removing iron impurities. The stem separation system separates the tobacco provided by the feeding system into stems and shreds, and then sends the uniform tobacco to the suction duct of the suction forming system. The separated tobacco stems and impurities are sent to the secondary sorting device for secondary separation. The suction forming system adsorbs the uniform, impurity-free, and stem-free tobacco provided by the stem separation system onto the suction belt to form a uniform tobacco bundle. After being trimmed by the inner and outer chopping knife disks of the leveler, it forms a tobacco strip with uniform weight and a tight end, which is transported to the tobacco gun of the YJ17 cigarette rolling machine for rolling.

[0003] The cigarette weight control system trims the tobacco bundle formed by the suction forming system to complete the weight control of the cigarette. According to the process requirements: 1. After trimming by the inner and outer chopping discs of the leveler, a tobacco strip with uniform weight and tight ends is formed. 2. In order to ensure the fullness of the end surface of the cigarette, the sliced ​​position of the cigarette with a tight end is ±2.0mm after the instrument detection. 3. The amount of tobacco residue at the rear end of the cigarette is less than 8mg / cigarette after the instrument detection.

[0004] See also Figure 1 The feed stripping machine splitter includes a splitter body 100, and the splitter body 100 is uniformly provided with a splitter groove 200 protruding downward along the circumferential direction. Before the improvement, the feed stripping machine splitter is made of a manganese steel sheet material. In order to prevent the splitter groove 200 from tearing during the stamping process, the inner side edge 300 (inner edge) of the splitter groove 200 is made into a straight edge, and the two side surfaces 500 are also vertical surfaces with straight edges. Since the outer edge of the splitter groove is an arc 400 and the inner edge 300 is a straight edge, the unit area is the largest at the center of the splitter groove, that is, the highest point 401 (outermost point) of the outer edge of the splitter groove.

[0005] It is demonstrated that the filling fullness of tobacco shreds on the end of cigarettes is the largest only when the blade is cut at the center of the chopper groove (the slicer position is 0). When the slicer position is not 0, the filling fullness of tobacco shreds on the end of cigarettes will decrease. The more it deviates from the center, the more the fullness decreases, and the more tobacco shreds fall off the end. The most direct reflection is the empty end of cigarettes and the large amount of waste rejection. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention develops a splitting knife for a feeding stripping machine to solve the problem that when the close slicing position of the end face of a cigarette is not in the exact center, the filling fullness of the tobacco shreds on the end face of the cigarette is consistent with that when the slicing position is in the exact center, thereby solving the problems of excessive shredded tobacco at the end face of the cigarette, hollow end face of the cigarette and a large amount of waste rejection.

[0007] The technical solution of the present invention to solve the technical problem is: The present application provides a cleaver for a material feeding strip forming machine, comprising a cleaver body, wherein the cleaver body is uniformly provided with cleaver grooves protruding downwards in a circumferential direction, wherein the cleaver grooves are arranged at the edge of the cleaver body, wherein the cleaver grooves comprise 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, wherein the inner arc surface is vertically connected between the inner edge of the bottom surface and the blade surface of the cleaver body, wherein the upper edge of the inclined side surface is connected to the blade surface of the cleaver body, wherein the lower edge of the inclined side surface is respectively connected to the left and right ends of the bottom surface, and wherein the inner edge of the inclined side surface is respectively connected to the left and right ends of the inner arc surface; 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; The chopping knife of the feeding strip forming machine is made by washing stainless steel machinery.

[0008] As an improvement of the above solution, the number of the riving knife grooves is 6.

[0009] Compared with the prior art, the above solution has the following advantages or beneficial effects: The present invention 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 position is not 0, the filling fullness of tobacco shreds on the end face of a cigarette is the same as when the slicer 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.

[0018] See also Figure 2-5 This embodiment provides a cleaver for a material feeding strip forming machine, comprising a cleaver body 1, the cleaver body 1 is evenly provided with 6 cleaver grooves 2 protruding downward along the circumferential direction, and the cleaver grooves 2 are provided at the edge of the cleaver body 1. Figure 3The riving knife 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 riving knife 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 riving knife body, the upper edge of the inclined side surface 5 is connected to the blade surface 11 of the riving knife body, the lower edges of the two inclined side surfaces 5 are 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.

[0019] 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 planing 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 chopper 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.

[0020] The inclined side surface 5 is arranged to be inclined upward. In the prior art, the vertical surface may suddenly reduce the tobacco shreds. By setting the inclined side surface 5, the tobacco shreds are gradually reduced, thus avoiding the phenomenon of tobacco shreds falling off the cigarettes due to the sudden reduction of tobacco shreds.

[0021] The cutting knife of the feeding strip forming machine is made of stainless steel machine, instead of the stamping method of manganese steel sheet in the prior art, which avoids the material tearing phenomenon caused by complex shape and compact size that affects the quality of cut tobacco.

[0022] Although the above describes the specific implementation mode of the invention in conjunction with the drawings, it is not intended to limit the scope of protection of the invention. Based on the technical solution of the present invention, 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 present invention.
