Description

Technical Field

[0001] The present application relates to the technical field of cigarette recycling and processing, and in particular to a cigarette filter cutting and separation device. Background Art

[0002] In the process of producing cigarette products, cigarette factories usually produce a large number of defective cigarettes. In order to avoid wasting raw materials, the tobacco in the defective cigarettes should be recycled and reused. For defective cigarettes containing bursting beads in the filter segment, in order to prevent the bursting beads from contaminating the tobacco during the tobacco recovery process, the filter segment should usually be removed first. The process of removing the filter segment is roughly as follows: the upstream cigarette sorting equipment sorts the position and state of the cigarettes, and then transfers the cigarettes to the periphery of the drum wheel. After the sorted cigarettes are transferred to the drum wheel, the filter segment of the cigarette can be suspended from the side of the drum wheel, and then the drum wheel drives the cigarette to rotate, and then the filter segment and the tobacco segment on the defective cigarette are separated from each other by shearing. When the filter segment and the tobacco segment are separated by shearing, due to the effect of shearing and extrusion, the end of the tobacco segment connected to the filter segment is thoroughly squeezed, causing the end of the tobacco segment to be severely flattened and deformed. In the subsequent separation of tobacco and cigarette paper, the separation between tobacco and cigarette paper is not thorough enough. Utility Model Content

[0003] The purpose of the present application is to provide a cigarette filter cutting and separation device, which will not cause deformation to the tobacco segment when separating the filter segment and the tobacco segment, thereby effectively solving the shortcomings of the prior art.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] like Figure 1-Figure 4 As shown, an embodiment of the present application provides a cigarette filter cutting and separation device for processing defective cigarettes, especially for processing defective cigarettes containing bursting beads, to cut off the filter segments on the defective cigarettes. In the past, when removing the filter segments of defective cigarettes containing bursting beads, the upstream cigarette sorting equipment sorted the cigarettes in state and position, and then transported the cigarettes to the cigarette drum wheel 90. After the sorted cigarettes are transported to the cigarette drum wheel 90, the filter segments of the cigarettes can be suspended out of the outside of the drum wheel 90 to remove the filter segments. The removal method is to shear, and during the shearing process, the end of the tobacco segment close to the filter segment will be squeezed and severely deformed. In the subsequent tobacco and cigarette paper separation process, the tobacco and cigarette paper at the deformed position are not easy to separate, resulting in incomplete tobacco recovery. The cutting and separation device of the present application is intended to avoid deformation of the tobacco segment when removing the filter segment of the cigarette paper, so as to make the subsequent separation of tobacco and cigarette paper more thorough.

[0026] The cigarette paper filter cutting and separating device comprises a mounting seat 80, on which a rotating shaft 100 is arranged, the rotating shaft 100 is rotatably mounted on the mounting seat 80, and the rotating shaft 100 extends axially in a direction away from the mounting seat 80, and further comprises a cutter 200, the number of which is two, and the two cutters 200 are axially spaced and arranged on the rotating shaft 100, the rotating shaft 100 can drive the cutter 200 to rotate, so that the cutter 200 can cut the cigarette in a rotating manner, and a driving device 300 is arranged on the mounting seat 80, and the driving device 300 drives the rotating shaft 100 to rotate. In this embodiment, the mounting seat 80 is a flat plate-shaped structure, and the drum wheel 90 and the rotating shaft 100 are mounted on the mounting seat 80. 0, the axis of the rotating shaft 100 and the axis of the drum wheel 90 are both perpendicular to the mounting seat 80. In the working state, the rotating outer peripheries of the two cutters 200 are respectively close to the axial outer sides of the circumference of the cigarette drum wheel 90, that is, after the cigarette is adsorbed by the drum wheel 90, the orientation of the cigarette is random. Therefore, by arranging a cutter 200 on each side, the filter segments suspended on both sides can be rotated and cut off respectively, without omission, and cutting is more convenient. Moreover, the rotary cutting method will not cause squeezing of the cigarette. After the filter segment is cut off, the incision on the tobacco segment is regular and complete, and the tobacco segment also maintains a regular shape, making the subsequent separation of tobacco and cigarette paper more thorough and smooth.

[0027] Preferably, the rotating surfaces of the two cutters 200 are parallel to each other, and the rotating surfaces of the cutters 200 and the cigarette paper drum 90 are also parallel. Therefore, when the cutters 200 cut the cigarettes, they cut perpendicularly to the periphery of the cigarettes. The cutters 200 are easier to intervene, less likely to deform the cigarettes, and the cuts are smoother.

[0028] More preferably, the cutter 200 is disc-shaped, and the cutter 200 and the rotating shaft 100 are coaxially connected. The coaxial cutter 200 rotates to cut the cigarette more smoothly. When the roller drives the cigarette close to the cutter 200, the cutter 200 intervenes in the cigarette more smoothly, further improving the effect of cutting the cigarette.

[0029] For the installation of the cutter 200, a through hole is provided in the middle of the cutter 200, through which the cutter 200 can be mounted on the rotating shaft 100, and a clamping member 4 is provided on both sides of the cutter 200 on the rotating shaft 100, and the clamping members 4 on both sides cooperate with each other to clamp the cutter 200 to achieve the installation of the cutter 200, and the clamping member 4 can be connected to the rotating shaft 100 by a threaded connection. Preferably, the clamping member 4 is also disc-shaped, and a through hole is provided in the middle of the clamping member 4, through which the clamping member 4 can be movably mounted on the rotating shaft 100, and the clamping member 4 and the rotating shaft 100 are coaxially arranged, one end of the rotating shaft 100 is connected to the mounting seat 80, and the other end of the rotating shaft 100 extends vertically outward, and the other end is taken as the outer end of the rotating shaft 100, and a step 101 is provided on the rotating shaft 100, and the step 101 protrudes from the outer periphery of the rotating shaft 100, and one side of the cutter 200 The clamping piece 4 can be lower than the step 101, and a limiting piece 5 is arranged between the clamping piece 4 on the other side of the cutter 200 and the clamping piece 4 on the corresponding side of the other cutter 200. A locking piece 6 is arranged at the end of the rotating shaft 100, and the locking piece 6 is pressed against the clamping piece 4 on the other side of the other cutter 200. The limiting piece 5 can also be movably mounted on the rotating shaft 100. When the cutter 200 is installed, the rotating shaft 100 along the direction away from the mounting seat 80 are respectively the step 101, the clamping piece 4, the cutter 200, the clamping piece 4, the limiting piece 5, the clamping piece 4, the cutter 200, the clamping piece 4 and the locking piece 6, and the various parts are pressed against each other, and the installation of the cutter 200 is achieved by means of set clamping, which is more convenient to install and has higher stability for the cutter 200. The locking piece 6 can be a screw and is coaxially screwed on the outer end of the rotating shaft 100.

[0030] In this embodiment, the limit member 5 is cylindrical, and a limit hole 51 is arranged on the outer periphery of the limit member 5. The limit hole 51 passes through the outer periphery of the limit member 5. A positioning hole 102 is arranged on the rotating shaft 100. The positioning hole 102 is radially opened on one side of the rotating shaft 100. The position of the limit hole 51 corresponds to the position of the positioning hole 102, which is convenient for screwing in the screws for limiting, so as to increase the overall stability of the assembly.

[0031] For the disc-shaped cutter 200, the blade on the outer periphery is formed on the outer side of the cutter 200, that is, the side away from the drum wheel 90. Due to the effect of the beveled surface of the blade, it is more conducive to the separation of the cut filter segment and the tobacco segment.

[0032] In this embodiment, the driving device 300 may include a driving motor, which is connected to the mounting seat 80 through an adjusting seat 81. The output end of the driving motor can be directly coaxially connected to the rotating shaft 100.
