[0001] This invention relates to the field of foreign object removal technology, and in particular to a tobacco leaf foreign object removal device and its usage method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Against the backdrop of rapid development in the tobacco industry, the requirements for cigarette manufacturing processes have gradually increased. The cigarette manufacturing process is not only an indispensable part of the cigarette production line, but also a key factor determining product competitiveness. Environmental factors in cigarette manufacturing are also considered part of the process requirements. Currently, cigarette manufacturing equipment has achieved a high degree of automation, but the high degree of interconnection between equipment results in many narrow gaps that may contain residual tobacco leaves or other foreign objects. If not cleaned promptly, these can accumulate and even cause mold, directly affecting the processability of cigarette manufacturing. Currently, cleaning foreign objects in corners or narrow spaces relies on traditional cleaning tools, which lack flexibility and specificity, and the cleaning effect is not ideal. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a tobacco leaf foreign object cleaning device and its usage method, which enables the cleaning of tobacco leaves or foreign objects in the corners of tobacco processing equipment. It is highly flexible, effectively reduces the labor intensity of workers, and ensures the process requirements of the tobacco production environment.

The slider is equipped with a transmission system and a working system. The working system includes an inner rod and a loading rod. The loading rod has a through hole along the axial direction. One end of the inner rod passes through the through hole of the loading rod and is equipped with a cleaning mechanism. The outer surface of the loading rod is spirally provided with multiple arc grooves along the generatrix direction. Arc disks are installed in the arc grooves. A first spring is provided between the arc grooves and the arc disks. The outer shell is provided with through holes corresponding to the arc disks. The transmission system includes a second motor and a third motor. The second motor drives the inner rod to rotate, and the third motor drives the loading rod to rotate.

[0006] As a further implementation, the outer shell includes a square frame and a cylinder. One side of the square frame is provided with a through hole, and one end of the cylinder is fixedly connected to the side of the square frame with the through hole, and the through holes of the two are coaxial. The cylinder has multiple rectangular holes spirally arranged along the generatrix, and each rectangular hole corresponds to an arc disk.

[0007] As a further implementation, a second motor is provided on the slider, and the output end of the second motor is connected to a first driving gear. The first driving gear meshes with a first driven gear, and the first driven gear is connected to the inner rod. The output end of a third motor is connected to a second driving gear, and the second driving gear meshes with a second driven gear, and the second driven gear is connected to the loading rod.

[0008] As a further implementation, the second driven gear is provided with a through hole, and the inner rod passes through the through hole of the second driven gear and enters the through hole of the loading rod.

[0009] As a further implementation, the cleaning mechanism includes a cross-shaped housing and a movable joint. The four ends of the cross-shaped housing are provided with four slotted structures, and a second spring is provided between the inner side of the slotted structure and the movable joint. There are four movable joints, which are installed in the four slot structures of the cross shell respectively, and the outer side of the slot structure is provided with a limiting block. The movable joint has a curved surface facing the cylinder on one side and a straight surface on the other side.

[0010] As a further implementation, the loading rod includes a load-bearing part and a transmission part. The arc groove has an arc of 120° and a number of 6. Starting from the connection between the load-bearing part and the transmission part of the loading rod, they are arranged spirally at equal intervals along the generatrix direction. Each arc groove rotates 60° relative to the previous arc groove around the circumference.

[0011] As a further implementation, a positioning frame is provided at the edge of the arc groove. The positioning frame has a through hole along the axial direction. The arc disk includes an arc surface and a bottom surface. A rotating column is provided on each side of one end of the arc surface. The through hole on the positioning frame is hinged to the rotating column on the arc disk. The bottom surface is fan-shaped, and the curvature of the fan shape is consistent with that of the curved surface. Between the two straight sides of the fan shape are two circular arc edges of different lengths, wherein the diameter of the shorter circular arc edge is larger than the diameter of the inner rod.

[0012] As a further implementation, a fixing plate is provided on the top wall inside the square frame. One end of the screw passes through the through hole on the fixing plate and is connected to the output end of the first motor. The first motor is fixedly installed on the side of the square frame close to the cylinder, and the other end of the screw is hinged to the through hole on the side of the square frame away from the cylinder.

[0014] A second aspect of the present invention provides a method of using a tobacco leaf foreign object cleaning device, which, based on the first aspect of the present invention, includes the following steps: Define the edge of the rectangular hole on the cylinder as the open point at the hinge between the arc disk and the loading rod, and the closed point as the point when rotated 60° towards the arc disk. In the initial state, the loading rod is at the closed point, and the cleaning mechanism is located inside the cylinder. At this time, under the action of the cylinder wall, the arc disk is in close contact with the loading rod, and the movable joint is retracted inside the cross shell. During operation, the cylindrical part of the tobacco foreign object cleaning device is inserted into the designated space. At this time, the first motor drives the inner rod to make linear motion, which drives the cleaning mechanism to extend out of the cylinder. Under the action of the second spring, the movable joint extends out of the cross shell and maintains a certain extension length under the limit action. When the cleaning mechanism reaches the position that needs to be cleaned, the second motor drives the cleaning mechanism to start rotating and cleaning through the inner rod. After cleaning is completed, the second motor stops, and the servo motor drives the loading rod to rotate to the open position through the gear. Under the action of the first spring, the arc disk unfolds. At this time, the cylinder will limit the arc disk to keep it at a certain opening. After the 6 arc disks unfold, they form a certain degree of closed space with the cylinder. Then, the foreign tobacco leaves cleaned in the designated space are taken out using this space.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention discloses a tobacco leaf foreign object cleaning device and its usage method. By cooperating between different motors, the cleaning mechanism stirs and loosens the tobacco leaf foreign objects in a designated space.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0022] Example 1 like Figure 1 , Figure 3 as well as Figure 8 As shown, this embodiment provides a tobacco foreign matter cleaning device, including a housing 1. The housing 1 is equipped with a transmission system, a state switching system and a working system. The housing 1 is provided with a rectangular hole 105 corresponding to the arc disk 3 of the working system, and the planar area of ​​the rectangular hole 105 is larger than that of the arc disk 3.

[0023] The working system includes an inner rod 4, a loading rod 2, and a cleaning mechanism. The loading rod 2 has a through hole 104 along the axial direction. One end of the inner rod 4 passes through the loading rod through hole 104 and is equipped with a cleaning mechanism. The outer surface of the loading rod 2 has a plurality of spiral grooves 204 spirally arranged along the generatrix direction. An arc disk 3 is installed in the arc groove 204. A first spring 7 is provided between the arc groove 204 and the arc disk 3.

[0024] The transmission system includes a second motor 11, a third motor 9, a first driving gear 19, a first driven gear 12, a second driving gear 14, and a second driven gear 15. The second motor 11 drives the inner rod 4 to rotate, and the third motor 9 drives the loading rod 2 to rotate. This design enables the transmission system to control the working system to perform cleaning operations during operation. The rotation of the inner rod 4 drives the rotation of the cleaning mechanism at its end to clean the equipment. The rotation of the loading rod 2 can open the semi-enclosed space between the arc disk 3 and the cylinder 101 to clean foreign objects from the tobacco leaves.

[0025] The state switching system includes a first motor 10, the output end of which is connected to a screw 16. A slider 18 is threaded onto the screw 16, and the slider 18 is equipped with a transmission system and a working system. Specifically, a second motor 11 is fixedly connected to the slider 18, and the output end of the second motor 11 is connected to a first driving gear 19, which meshes with a first driven gear 12. The first driven gear 12 is connected to an inner rod 4. A third motor 9 is fixedly connected to the side of the square frame 102 near the cylinder 101. The output end of the third motor 9 (in this embodiment, the third motor 9 is a servo motor) is connected to a second driving gear 14, which meshes with a second driven gear 15. The second driven gear 15 is connected to a loading rod 2. The second driven gear 15 has a through hole, through which the inner rod 4 passes and enters the through hole of the loading rod 2. This design allows the working system and transmission system to move linearly with the slider 18, thereby switching working states.

[0026] The outer casing 1 includes a square frame 102 and a cylindrical shell 101. One side of the square frame 102 has a through hole, and one end of the cylindrical shell 101 is fixedly connected to the side of the square frame 102 with the through hole, and the through holes of the two are coaxial. The cylindrical shell 101 has six rectangular holes 105 spirally arranged along the generatrix direction, and the included angle between two adjacent rectangular holes 105 along the circumferential direction is 60°. The rectangular holes 105 correspond one-to-one with the arc disk 3.

[0027] like Figure 6As shown, the cleaning mechanism includes a cross-shaped housing 6 and movable joints 5. The four ends of the cross-shaped housing 6 have four slotted structures inside. Four movable joints 5 are installed in the four slotted structures of the cross-shaped housing 6. A second spring 13 is provided between the inner side of the slotted structure and the movable joint 5. A limiting block is provided on the outer side of the slotted structure. The movable joint 5 has an arc-shaped surface facing the cylinder 101 and a straight surface on the other side. This design allows the movable joint 5 to retract inside the cross-shaped housing 6 when not in operation due to the action of the cylinder wall of the cylinder 101. Figure 7 As shown, when switched to the working state, the movable joint 5 extends out of the cross shell 6 under the action of the second spring 13, and only maintains a certain extension length under the action of the limiting block on the outside of the slot structure.

[0028] like Figure 4 As shown, the loading rod 2 includes a bearing part 201 and a transmission part 202. The bearing part 201 is located inside the through hole of the cylinder 101, and the positioning frame 203 and the arc groove 204 are both located on the bearing part 201. The arc groove 204 has an arc of 120° and there are 6 of them. They are arranged spirally and equidistantly along the generatrix direction starting from the connection between the bearing part 201 and the transmission part 202 of the loading rod 2. Each subsequent arc groove 204 is rotated 60° relative to the previous arc groove 204 around the circumference. An arc disk 3 is installed inside the arc groove 204, such as... Figure 2 As shown, six arc disks with three spirals are arranged around the cylinder 101.

[0029] A positioning frame 203 is provided at the edge of the arc groove 204. The positioning frame 203 is fixed to the surface of the bearing part 201, and the positioning frame 203 has a through hole along the axial direction. Figure 9 As shown, the arc disk 3 includes an arc surface 301 and a bottom surface 302. A rotating column 303 is provided on each side of one end of the arc surface 301 of the arc disk 3. The through hole on the positioning frame 203 is hinged to the rotating column 303 on the arc disk 3. When the arc disk 3 is in close contact with the loading rod 2, the bottom surface 302 of the arc disk 3 is inserted into the arc groove 204. Because a first spring 7 is provided between the arc groove 204 and the arc disk 3, under the action of the first spring 7, the arc disk 3 unfolds around the through hole of the positioning frame 203 and is limited by the cylinder 101. At this time, the arc disk 3 and the cylinder 101 form a semi-enclosed space, which helps to clean foreign objects from the tobacco leaves.

[0030] The bottom surface 302 is fan-shaped, and the curvature of the fan shape is consistent with the curvature of the arc surface 301. There are two arc edges of different lengths between the two straight edges of the fan shape. The diameter of the shorter arc edge is larger than the diameter of the inner rod 4. This design makes it easy to avoid interfering with the movement of the inner rod 4 when the inner rod 4 is close to the loading rod 2.

[0031] The top wall inside the square frame 102 is provided with a fixing plate 103. One end of the screw 16 passes through a through hole in the fixing plate 103 and is connected to the output end of the first motor 10. The first motor 10 is fixedly installed on the side of the square frame 102 near the cylinder 101, and the other end of the screw 16 is hinged to a through hole on the side of the square frame 102 away from the cylinder 101. This design makes the rotation of the screw 16 driven by the motor more stable.

[0032] like Figure 5 As shown, a fixed frame 20 is provided on the slider 18. The fixed frame 20 is "L" shaped. The shorter end of the "L" shape is fixed to the slider 18, and the longer end is provided with a through hole. The inner rod 4 is rotatably connected to the through hole on the fixed frame 20. The inner rod 4 passes through the through hole of the fixed frame 20 and is connected to the first driven gear 12. This design makes the linear motion of the inner rod 4 with the slider 18 more stable.

[0033] The transmission system also includes a guide rod 17, which passes through the slider 18. One end of the guide rod 17 is connected to the fixed plate 103, and the other end is connected to the side of the square frame 102 away from the cylinder 101. The guide rod 17 guides the slider 18, and the design of the guide rod 17 makes the threaded movement between the slider 18 and the screw 16 more stable.

[0034] The tobacco foreign matter cleaning device of the present invention also includes handles 8, the number of handles 8 is two, the handles 8 are in the shape of "T", and are fixedly installed to the two sides of the square frame 102 through the bottom of the "T", so that the axis of symmetry of the handles 8 is perpendicular to the axis of the cylinder 101.

[0035] Example 2 This embodiment provides a method for using a tobacco leaf foreign object cleaning device, based on the tobacco leaf foreign object cleaning device of Embodiment 1, including the following steps: Define the edge of the rectangular hole on the cylinder as the open point at the hinge between the arc disk and the loading rod, and the closed point as the point when rotated 60° towards the arc disk. In the initial state, the loading rod is at the closed point, and the cleaning mechanism is located inside the cylinder. At this time, under the action of the cylinder wall, the arc disk is in close contact with the loading rod, and the movable joint is retracted inside the cross shell. During operation, the cylindrical part of the tobacco foreign object cleaning device is inserted into the designated space. At this time, the first motor drives the inner rod to make linear motion, which drives the cleaning mechanism to extend out of the cylinder. Under the action of the second spring, the movable joint extends out of the cross shell and maintains a certain extension length under the limit action. When the cleaning mechanism reaches the position that needs to be cleaned, the second motor drives the cleaning mechanism to start rotating and cleaning through the inner rod. After cleaning is completed, the second motor stops, and the servo motor drives the loading rod to rotate to the open position through the gear. Under the action of the first spring, the arc disk unfolds. At this time, the cylinder will limit the arc disk to keep it at a certain opening. After the 6 arc disks unfold, they form a certain degree of closed space with the cylinder. Then, the foreign tobacco leaves cleaned in the designated space are taken out using this space.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0037] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
