Description

Technical Field

[0001] This invention relates to the field of cigarette packaging technology, and in particular to a device for compacting cigarettes and tobacco shreds in a cigarette packaging machine. Background Technology

[0002] Empty ends in cigarettes are a common quality defect in cigarette manufacturing. Specifically, it manifests as tobacco shreds falling off at the lit end of the cigarette, resulting in incomplete filling and easily causing consumer dissatisfaction. There are many reasons for empty ends in cigarettes, including the tobacco blend ratio, tobacco structure, rolling process parameters, cigarette conveying process, and packaging process.

[0003] The rolled cigarettes are conveyed from the cigarette rolling machine to the packaging machine via conveyor belts and other equipment. During the conveying process, the cigarettes roll and squeeze against each other, causing the tobacco at the lit end of the cigarette to become soft and loose. This makes it easy for the tobacco to fall off during the packaging process, resulting in a hollow cigarette defect. The hollow cigarette detection device on the packaging machine will reject the hollow cigarettes that exceed the quality standard, resulting in significant production waste. Summary of the Invention

[0004] The purpose of this invention is to provide a tobacco compacting device for cigarette packaging machines, which can compact loose tobacco again, reduce the occurrence of tobacco falling off during cigarette packaging, reduce the empty cigarette rate, and thus reduce production waste caused by removing empty cigarettes.

[0027] The present invention provides a cigarette packing machine tobacco compaction device. In use, a drive assembly drives a swing frame to swing around a fixed axis. The swing frame moves a first connecting rod and a second connecting rod. The first connecting rod causes a first push rod to slide relative to a first guide sleeve, causing the first push rod to move a first bracket closer to the lit end of the cigarette. Simultaneously, the second connecting rod causes a second push rod to slide relative to a second guide sleeve, causing the second push rod to move a second bracket closer to the sucking end of the cigarette. A first air hole on the first bracket is close to the lit end of the cigarette, and a second air hole on the second bracket is close to the sucking end of the cigarette. A first ventilation pipe provides positive pressure air to the first air hole, and the positive pressure air blows air through the first air hole onto the lit end of the cigarette, compacting the tobacco inside the cigarette with the positive pressure air. The two ventilation pipes supply negative pressure air to the second air hole. This negative pressure air is drawn into the suction end of the cigarette through the second air hole, compacting the tobacco inside the cigarette. After the tobacco is compacted, the first and second ventilation pipes stop supplying air, and the drive assembly continues to drive the swing frame to swing around the fixed axis. The swing frame moves the first and second connecting rods. The first connecting rod causes the first push rod to slide relative to the first guide sleeve, causing the first push rod to move the first support away from the lit end of the cigarette. Simultaneously, the second connecting rod causes the second push rod to slide relative to the second guide sleeve, causing the second push rod to move the second support away from the suction end of the cigarette. The first air hole on the first support moves away from the lit end of the cigarette, and the second air hole on the second support moves away from the suction end of the cigarette. By using this tobacco compacting device for cigarette packaging machines, loose tobacco can be compacted again, reducing the occurrence of tobacco falling off during cigarette packaging, reducing the empty cigarette rate, and thus reducing production waste caused by removing empty cigarettes.

[0039] like Figure 1 and Figure 2As shown, the present invention provides a cigarette packing device for a cigarette packaging machine, comprising a pushing mechanism 100, a first translation mechanism 200, a second translation mechanism 300, a first support 400, and a second support 500. The pushing mechanism 100 includes a driving assembly 110, a swing frame 120, a first connecting rod 130, and a second connecting rod 140. The swing frame 120 has a rotating hole 121, through which a fixed shaft passes and is fixedly connected to a wall panel. The fixed shaft is rotatably connected to the rotating hole 121. The driving assembly 110 is hinged to the right end of the swing frame 120. One end of the first connecting rod 130 is hinged to the upper end of the swing frame 120, and one end of the second connecting rod 140 is hinged to the lower end of the swing frame 120. The first translation mechanism 200 includes a first guide sleeve 210, a first push rod 220, and a first connecting block 230. The first guide sleeve 210 is fixedly mounted on the wall panel, the first push rod 220 slides through the first guide sleeve 210, one end of the first connecting block 230 is fixedly connected to one end of the first push rod 220, and the other end of the first connecting block 230 is hinged to the end of the first connecting rod 130 away from the swing frame 120. The second translation mechanism 300 includes a second guide sleeve 310 and a second push rod. The second connecting block 320 and the second connecting block 330, the second guide sleeve 310 are fixedly mounted on the wall panel, the second push rod 320 slides through the second guide sleeve 310, one end of the second connecting block 330 is fixedly connected to one end of the second push rod 320, and the other end of the second connecting block 330 is hinged to the end of the second connecting rod 140 away from the swing frame 120; one end of the first bracket 400 is connected to the end of the first push rod 220 away from the first connecting block 230, one side of the first bracket 400 is provided with a first air hole 410, and the other side of the first bracket 400 is connected with a first ventilation pipe 420, and the first air hole 410 communicates with the first ventilation pipe 420; one end of the second bracket 500 is connected to the end of the second push rod 320 away from the second connecting block 330, one side of the second bracket 500 is provided with a second air hole 510 aligned with the first air hole 410, and the other side of the second bracket 500 is connected with a second ventilation pipe 520, and the second air hole 510 communicates with the second ventilation pipe 520. Specifically, the rotating hole 121 is located at the left end of the swing frame 120.

[0040] The cigarette packing device for a cigarette packaging machine provided by the present invention, in use, drives the swing frame 120 to swing around a fixed axis via the drive assembly 110. The swing frame 120 drives the first connecting rod 130 and the second connecting rod 140 to move. The first connecting rod 130 drives the first push rod 220 to slide relative to the first guide sleeve 210, so that the first push rod 220 drives the first bracket 400 to move closer to the lit end of the cigarette 10. At the same time, the second connecting rod 140 drives the second push rod 320 to slide relative to the second guide sleeve 210. The guide sleeve 310 slides, causing the second push rod 320 to move the second bracket 500 closer to the suction end of the cigarette 10. The first air hole 410 on the first bracket 400 is close to the ignition end of the cigarette 10, and the second air hole 510 on the second bracket 500 is close to the suction end of the cigarette 10. The first ventilation pipe 420 provides positive pressure air to the first air hole 410. The positive pressure air blows air through the first air hole 410 to the ignition end of the cigarette 10, so that the tobacco inside the cigarette 10 is compacted by the positive pressure air. The second ventilation pipe... The first ventilation pipe 420 supplies negative pressure air to the second vent 510, which draws air into the suction end of the cigarette 10, compacting the tobacco inside the cigarette 10. After the tobacco in the cigarette 10 is compacted, the first ventilation pipe 420 and the second ventilation pipe 520 stop supplying air, and the drive assembly 110 continues to drive the swing frame 120 to swing around the fixed axis. The swing frame 120 drives the first connecting rod 130 and the second connecting rod 140 to move, and the first connecting rod 130 drives the first push... The rod 220 slides relative to the first guide sleeve 210, causing the first push rod 220 to move the first bracket 400 away from the ignition end of the cigarette 10. Simultaneously, the second connecting rod 140 causes the second push rod 320 to slide relative to the second guide sleeve 310, causing the second push rod 320 to move the second bracket 500 away from the suction end of the cigarette 10. The first air hole 410 on the first bracket 400 moves away from the ignition end of the cigarette 10, and the second air hole 510 on the second bracket 500 moves away from the suction end of the cigarette 10. By using this cigarette packing machine's tobacco compacting device, loose tobacco can be compacted again, reducing the occurrence of tobacco falling off during the cigarette packing process, lowering the empty cigarette rate, and thus reducing production waste caused by removing empty cigarettes 10.

[0041] In some embodiments, the drive assembly 110 includes a drive shaft 111, an eccentric disk 112, and a transmission link 113. The drive shaft 111 is connected to the output end of the drive component; the eccentric disk 112 is fixedly connected to the drive shaft 111, and the axis of the eccentric disk 112 is parallel to but does not coincide with the axis of the drive shaft 111; one end of the transmission link 113 has a rotating hole 113a, which is fitted onto the eccentric disk 112 and rotatably connected to it; the other end of the transmission link 113 is hinged to the right end of the swing frame 120. In use, the drive component drives the drive shaft 111 to rotate, the drive shaft 111 drives the eccentric disk 112 to rotate, the rotation of the eccentric disk 112 drives the transmission link 113 to swing, and the transmission link 113 drives the swing frame 120 to swing around a fixed axis. Specifically, the drive component may be, but is not limited to, a stepper motor or other drive elements capable of driving the drive shaft 111 to rotate.

[0042] In some embodiments, the axis of the first guide sleeve 210 is parallel to the axis of the second guide sleeve 310, such that the movement path of the first push rod 220 is parallel to the movement path of the second push rod 320. The angle between the first connecting block 230 and the first push rod 220 is adjustable, and the angle between the second connecting block 330 and the second push rod 320 is adjustable. By adjusting the angle between the first connecting block 230 and the first push rod 220, and the angle between the first connecting block 230 and the first push rod 220, the minimum relative distance between the first bracket 400 and the second bracket 500 during movement can be adjusted to accommodate cigarettes 10 of different lengths.

[0043] In some embodiments, a first support block 440 is provided at one end of the first bracket 400. The first bracket 400 is connected to the first push rod 220 through the first support block 440, and the position of the first support block 440 on the first push rod 220 can be adjusted along the axial direction of the first push rod 220. A second support block 540 is provided at one end of the second bracket 500. The second bracket 500 is connected to the second push rod 320 through the second support block 540, and the position of the second support block 540 on the second push rod 320 can be adjusted along the axial direction of the second push rod 320. By adjusting the axial positions of the first support block 440 and the second support block 540 on the first push rod 220, the minimum relative distance between the first bracket 400 and the second bracket 500 during movement can be adjusted to accommodate cigarettes 10 of different lengths. Furthermore, the horizontal position of the first bracket 400 and the second bracket 500 during movement can also be adjusted.

[0044] In some embodiments, the axis of the first support 400 is parallel to the axis of the second support 500, and the axis of the first support 400 and the axis of the second support 500 are at the same horizontal height. With the above structure, when the first support 400 and the second support 500 are close to each other, the tobacco of the cigarette 10 located at the same horizontal height can be compacted.

[0045] Specifically, the number of first air holes 410 is one or more, and the multiple first air holes 410 are evenly arranged along the axis of the first support 400 on the side of the first support 400 near the second support 500; the number of second air holes 510 is one or more, and the multiple second air holes 510 are evenly arranged along the axis of the second support 500 on the side of the second support 500 near the first support 400. The number of first air holes 410 and second air holes 510 is selected according to the required number of tightly packed cigarettes 10. The distance between two adjacent first air holes 410 is the same as the distance between two adjacent second air holes 510, and the distance between two adjacent first air holes 410 is the distance between two adjacent cigarettes 10. Figure 1 For example, the first air hole 410 is the blowing air hole, and the second air hole 510 is the suction air hole.

[0046] In some embodiments, a first support sleeve 430 is fitted onto a first ventilation duct 420, the first support sleeve 430 being slidably connected to the first ventilation duct 420 and fixedly connected to a wall panel; a second support sleeve 530 is fitted onto a second ventilation duct 520, the second support sleeve 530 being slidably connected to the second ventilation duct 520 and fixedly connected to a wall panel. By providing the first support sleeve 430, the first ventilation duct 420 can be supported, thereby stabilizing the first support 400; by providing the second support sleeve 530, the second ventilation duct 520 can be supported, thereby stabilizing the second support 500. Exemplarily, both the first support sleeve 430 and the second support sleeve 530 are at the same horizontal height as the first guide sleeve 210, and the axes of both the first support sleeve 430 and the second support sleeve 530 are parallel to the axis of the first guide sleeve 210.

[0047] In order to facilitate the control of the conduction of the first ventilation pipe 420 and the second ventilation pipe 520, in some embodiments, both the first ventilation pipe 420 and the second ventilation pipe 520 are equipped with solenoid valves.

[0048] The technical solution adopted by this invention to solve its technical problem is as follows: compressed air is blown along the axial direction of the cigarette 10 to the lit end of the cigarette 10, while negative pressure is used to draw air from the suction end of the cigarette 10, ensuring that the soft tobacco becomes compact again. To prevent the compressed air column from being misaligned with the axis of the cigarette 10 and blowing out the tobacco, the device is installed during the process of the cigarette 10 arranging and falling. Because the position of the cigarette 10 is no longer random during this process and has a relatively precise positioning, only the positions of the first air hole 410 and the second air hole 510 in the device need to be adjusted to achieve coaxiality.

[0049] The descent of the cigarettes 10 is an intermittent process. When the pusher plate pushes out the bottom layer of cigarettes 10, the entire descent channel is paused. After the pusher plate returns to its original position, the cigarettes 10 in the descent channel fall by their own weight up to the diameter of a cigarette. When the cigarettes 10 are paused, the pusher mechanism 100, through the first translation mechanism 200, moves the first support 400 closer to the lit end of the cigarette 10. The pusher mechanism 100, through the second translation mechanism 300, moves the second support 500 closer to the sucking end of the cigarette 10. The first air hole 410 on the first support 400 is close to the lit end of the cigarette 10, and the second air hole 510 on the second support 500 is close to the sucking end of the cigarette 10. To avoid damage to the cigarettes 10 due to contact, the minimum relative distance between the first air hole 410 and the second air hole 510 during the movement is slightly greater than the length of the cigarette 10. The combined action of positive and negative pressure air makes the tobacco inside the cigarette 10 axially compact.

[0050] After the push plate is reset, in order not to interfere with the normal falling of the cigarettes 10 arranged in the falling channel, the solenoid valve controls the first ventilation pipe 420 and the second ventilation pipe 520 to stop conducting. The push mechanism 100 drives the first support 400 away from the lit end of the cigarette 10 through the first translation mechanism 200. The push mechanism 100 drives the second support 500 away from the sucking end of the cigarette 10 through the second translation mechanism 300. The first air hole 410 on the first support 400 moves in the opposite direction away from the lit end of the cigarette 10. The second air hole 510 on the second support 500 moves in the opposite direction away from the sucking end of the cigarette 10. Due to the combined action of blowing and sucking, the cigarette 10 will move axially towards the sucking direction. The cigarette 10 is not completely located in the center of the falling channel in the length direction. Therefore, the second air hole 510 at the suction end will guide the compressed air in the opposite direction, blowing the cigarette 10 slightly away in the opposite direction to a certain distance, ensuring that the cigarette 10 is located in the center of the falling channel when it falls, thus avoiding interference during the falling process of the suction end.

[0051] Repeat the above actions when the cigarette is 10.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
