Description

Technical Field

[0001] The utility model relates to the technical field of cigarette making equipment, in particular to a flexible smoke protection device at a cigarette outlet of a cigarette making machine. Background Art

[0002] The smoke outlet drum of the YJ29 receiving machine is located at the smoke outlet of the drum of the PASSIM cigarette making machine. It is the last step in the process of conveying cigarettes through the drum. After the cigarettes have been received, tested, and rejected in the previous steps, they are output by the smoke outlet drum to the cigarette output system. The cigarette output system then stacks them and delivers them to the downstream machines in a large flow rate. The output system of the YJ29 receiving machine completes the cigarette output function. It is a large flow output form that converts the internal and external exhaust cigarettes into a single row of cigarette output. The output system consists of two parts: cigarette stacking and cigarette turning output. Figure 9 As shown, the cigarette stacking part is composed of a transfer shovel 30 and a conveyor belt 40. The concave part of one side of the transfer shovel 30 connects to the cigarette outlet drum 20, and the concave part of the other side of the transfer shovel 30 connects to the conveyor belt 40.

[0003] The transfer shovel is not tightly connected to the smoke drum and the conveyor belt. The smoke drum and conveyor belt are both moving parts, while the transfer shovel is a stationary component. Therefore, the transfer shovel is separately fixed and has a certain gap between them to prevent it from rubbing against the drum and the conveyor belt. The transfer shovel's function is to remove single-layer cigarettes from the smoke drum, creating a large multi-layer flow of cigarettes for delivery to the conveyor belt. When the cigarettes meet the transfer shovel, the rotating smoke drum directly impacts the transfer shovel, removing the cigarettes from the stack and discharging them onto the conveyor belt. However, this impact often causes cigarettes to bounce or jump out of the smoke outlet, disrupting the arrangement of cigarettes at the top of the stack. Utility Model Content

[0038] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figures 1 to 9 As shown, the utility model provides a flexible smoke protection device for a cigarette making machine smoke outlet, comprising a smoke shield 100, a connecting arm 200, a movable adjustment joint 300, a V-shaped bent plate 400, a connecting piece 500 and a protective cover 600.

[0040] The smoke shield 100 includes a curved smoke shield 110 and a connecting block 120. A square through-hole 111 is provided on the bottom of the curved smoke shield 110. A raised square platform 112 is provided on the bottom of the curved smoke shield 110. The raised square platform 112 is close to the square through-hole 111. The connecting block 120 is provided on the top of the curved smoke shield 110. The connecting block 120 is welded and fixed on the top of the curved smoke shield 110, and the connecting block 120 is tightly connected to the curved smoke shield 110.

[0041] The connecting arm 200 includes a support shaft 210, an arm body 220, a top shaft 230 and a spring 240. The support shaft 210 is rotatably connected to the connecting block 120. The arm body 220 is arranged on the frame 10. The end of the support shaft 210 is connected to the arm body 220. The top of the arc-shaped smoke shield 110 can abut against the top shaft 230. One end of the spring 240 is connected to the arm body 220, and the other end of the spring 240 is connected to the connecting block 120. Under normal circumstances, the spring 240 is in a relaxed state, and the spring 240 pulls the curved smoke baffle 110 through the connecting block 120 to form a smoke-passing and handover channel, which allows a single layer of cigarettes to pass through. At this time, due to the action of gravity, the top of the curved smoke baffle 110 is against the top shaft 230, and the top shaft 230 acts as a limiter; when there are too many cigarettes at the smoke outlet and the height of the multiple layers of cigarettes is high, the curved smoke baffle 110 is rotated clockwise around the support shaft 210 by a certain angle through the connecting block 120, and the smoke-passing and handover channel formed becomes wider, allowing more cigarettes to pass through buffered, and the spring 240 is in a tensioned state at this time; when the excessive cigarettes at the smoke outlet are discharged, the spring 240 will automatically relax, and the curved smoke baffle 110 will return to its normal working state.

[0042] The movable adjustment joint 300 includes an upper hinge plate 310, a hinge shaft 320, and a lower hinge plate 330. The upper hinge plate 310 is disposed above the bottom of the curved smoke shield 110 and is adjacent to the square through-hole 111. The hinge shaft 320 is rotatably connected to the upper hinge plate 310, and the lower hinge plate 330 is rotatably connected to the hinge shaft 320. The upper hinge plate 310 and the lower hinge plate 330 are rotatable about the hinge shaft 320.

[0043] The upper side of the V-shaped plate 400 is connected to the lower hinge plate 330 near the bend. A counterweight 410 is provided on the upper exterior of the V-shaped plate 400. The lower side of the V-shaped plate 400 passes through the square through-hole 111. The lower side of the V-shaped plate 400 is provided with a connecting platform 420. Under normal circumstances, when a large flow of medium- and multi-layer cigarettes is normally conveyed, the lower side of the V-shaped plate 400 is closely attached to the raised square platform 112 of the curved smoke barrier 110 under the influence of the multi-layer cigarettes. At this time, the connecting platform 420 of the V-shaped plate 400 also closely attaches to the raised square platform 112 of the curved smoke barrier 110 on the lower side. When the number of cigarettes in high volume decreases, due to the gravity of the counterweight 410 and the rotatable nature of the movable adjustment joint 300, the V-shaped curved plate 400 will rotate counterclockwise about the hinge axis 320, bringing the V-shaped curved plate 400 closer to the smoke outlet drum 20. This reduces the space at the smoke outlet, facilitating the stacking of cigarettes from a single layer into multiple layers. At this point, the lower side of the V-shaped curved plate 400 and its connecting platform 420 are both separated from the raised square platform 112 of the arc-shaped smoke baffle 110. When the number of cigarettes in high volume increases, driven and supported by the multiple layers of cigarettes, the V-shaped curved plate 400 will rotate clockwise about the hinge axis 320, moving the V-shaped curved plate 400 further away from the smoke outlet drum 20. This increases the space at the smoke outlet, facilitating the faster discharge of multiple layers of cigarettes.

[0044] The connector 500 includes a connecting plate 510 and a backing plate 520. The upper side of the connecting plate 510 is connected to the connecting platform 420, and the backing plate 520 is connected to the lower side of the connecting plate 510. When the lower side of the V-shaped bent plate 400 and the connecting platform 420 of the V-shaped bent plate 400 are both separated from the raised square platform 112 of the curved smoke damper 110, the upper side of the connecting plate 510 is also separated from the raised square platform 112 of the curved smoke damper 110. When the lower side of the V-shaped bent plate 400 and the connecting platform 420 of the V-shaped bent plate 400 are both in close contact with the raised square platform 112 of the curved smoke damper 110, the upper side of the connecting plate 510 is also in close contact with the raised square platform 112 of the curved smoke damper 110. For example, the connecting plate 510 may be, but is not limited to, a bent plate structure.

[0045] The protective cover 600 includes a steel mesh 610 and a plastic belt 620 . The steel mesh 610 is disposed above the plastic belt 620 . The steel mesh 610 and the plastic belt 620 are sandwiched between the backing plate 520 and the connecting plate 510 .

[0046] The flexible smoke protection device for the smoke outlet of a cigarette making machine provided by the present invention realizes the transportation of cigarettes at the smoke outlet through a two-stage flexible structure. The first stage is a spring 240 pulling the arc-shaped smoke baffle 110 to form a smoke-passing and handover channel. The smoke-passing and handover channels of different sizes are formed in the tensioned state of the spring 240 to realize the smooth transportation of cigarettes. The second stage is a movable adjustment joint 300 and a protective cover 600. The weight of the counterweight block 410 drives the V-shaped bent plate 400 and the protective cover 600 to move closer or closer to the smoke outlet drum 20 to realize the stacking and leveling of the cigarettes during transportation.

[0047] In some embodiments, the connecting block 120 defines a rotation hole 121, through which the support shaft 210 passes, and the support shaft 210 is rotatably connected. This structure enables the smoke shield 100 to rotate about the support shaft 210. For example, the connecting block 120 may be, but is not limited to, a columnar structure.

[0048] In some embodiments, the arm body 220 has a through-hole at one end away from the support shaft 210, through which a fixing screw 221 passes to be screwed to the frame 10. The frame 10 has an adjustment slot 11, through which an adjustment screw 250 passes to be screwed to the frame 10. The adjustment screw 250 supports the bottom of the arm body 220. The arm body 220 is supported by the adjustment screw 250 due to gravity; by changing the position of the adjustment screw 250 in the adjustment slot 11, the angle of the arm body 220 relative to the smoke shield 100 can be adjusted.

[0049] In some embodiments, the support shaft 210 is provided with an inner limit block 211 and an outer limit block 212. The inner limit block 211 and the outer limit block 212 are adjustable along the axial direction of the support shaft 210, and the connecting block 120 is located between the inner limit block 211 and the outer limit block 212. After loosening their respective fastening screws, the inner limit block 211 and the outer limit block 212 can slide along the axial direction of the support shaft 210. After tightening their respective fastening screws, their positions become unadjustable. The inner and outer positions of the smoke shield 100 can be adjusted by changing the positions of the inner limit block 211 and the outer limit block 212 relative to the axis of the smoke shield 100.

[0050] In some embodiments, the hinge upper plate 310 is fixed to a position above the square through hole 111 of the arc-shaped smoke baffle 110 by a countersunk screw, and the nut portion of the countersunk screw is at the lower portion of the arc-shaped smoke baffle 110 .

[0051] In some embodiments, the V-shaped plate 400 is V-shaped, with the lower side of the V-shaped plate 400 widened to form a connecting platform 420. The upper side of the V-shaped plate 400 is welded and fixedly connected to the hinge lower plate 330 near the bend. The upper outer side of the V-shaped plate 400 is fixedly connected to the counterweight 410 via screws.

[0052] The working principle of the flexible smoke protection device at the cigarette outlet of the cigarette making machine provided by the utility model is as follows:

[0053] In the smoke-free state, spring 240 pulls curved smoke deflector 110 via connecting block 120 to form a smoke passageway only wide enough for a single layer of smoke. Under the weight of counterweight 410, the underside of V-shaped curved plate 400 and its connecting platform 420 are separated from the raised square platform 112 of curved smoke deflector 110. V-shaped curved plate 400 is positioned close to the smoke outlet drum 20, creating a smaller smoke outlet. At this point, spring 240 is relaxed, curved smoke deflector 110 is pressed against top shaft 230, counterweight 410 is at its lowest travel position, and the movable adjustment joint 300 is at its maximum angle.

[0054] As the number of cigarettes increases, spring 240 gradually tightens the curved smoke deflector 110, forming a smoke passageway that widens from the width of a single layer of cigarettes. Driven and supported by the multiple layers of cigarettes, the underside of the V-shaped curved plate 400 and its connecting platform 420 gradually press against the raised square platform 112 of the curved smoke deflector 110. The V-shaped curved plate 400 gradually moves away from the smoke outlet drum 20, gradually expanding the smoke outlet space. At this point, spring 240 is gradually tensioned, the curved smoke deflector 110 gradually moves away from the top shaft 230, the counterweight 410 gradually moves upward, and the angle of the movable adjustment joint 300 gradually decreases.

[0055] As the number of cigarettes decreases, spring 240 gradually relaxes, allowing curved smoke deflector 110 to form a smoke passageway. This passageway narrows from wide to the width of a single layer of cigarettes. Under the weight of counterweight 410, the lower side of V-shaped curved plate 400 and its connecting platform 420 gradually separate from the raised square platform 112 of curved smoke deflector 110, and V-shaped curved plate 400 gradually approaches smoke outlet drum 20, gradually reducing the space in the smoke outlet. At this point, spring 240 gradually relaxes, curved smoke deflector 110 gradually approaches top shaft 230, counterweight 410 gradually moves downward, and the angle of movable adjustment joint 300 gradually increases.

[0056] It can be seen from the above technical solution that compared with the prior art, the present invention has the following beneficial effects:

[0057] 1. This technical solution does not change the original cigarette handover and transportation process. By adding this device on the upper side of the smoke outlet, it is simple and feasible, ensuring the stability of the cigarette handover and transportation process at the smoke outlet.

[0058] 2. Two-level flexible protection ensures smooth cigarette conveyance at the outlet. Spring 240 tightens the curved smoke baffle 110 to form a smoke passageway, ensuring smooth cigarette conveyance. The movable adjustable joint 300 and protective cover 600 level the cigarettes during conveyance. Existing solutions simply add a plastic belt above the smoke outlet drum 20 to cover the layers of cigarettes, leveraging the belt's weight and the direction of high-flow cigarette output to level the layers, resulting in poor results.

[0059] 3. Variable smoke transfer channel for smooth transfer and stacking. The spring 240 pulls the curved smoke baffle 110 to form the smoke transfer channel. The spring 240 is in a tensioned state to form different sizes of smoke transfer channels, ensuring smooth delivery of cigarettes and preventing blockage and smoke straying at the smoke outlet.

[0060] 4. Adaptive protective cover 600 ensures smooth stacking, leveling, and conveying. The weight of the counterweight 410 drives the V-shaped curved plate 400 and the protective cover 600 to adjust their distance from the smoke outlet drum 20, achieving stacking and leveling during cigarette conveying and reducing quality defects during the cigarette conveying process.

[0061] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
