Description

Technical Field

[0001] The present invention relates to the technical field of cigarette making equipment, and in particular to a device for cutting waist-shaped holes in aluminum foil and a method for using the device. Background Art

[0002] Popping bead cigarettes are cigarettes with a small liquid bead inside the filter. The liquid inside this small bead can make the cigarette more fragrant during the sucking process, enhancing the aroma or characteristics, making the smoker have a more comfortable experience. To make it easier for both buyers and sellers to judge the specific flavor of popping bead cigarettes, corresponding waist-shaped holes are cut into the aluminum foil between the cigarette box and the popping bead cigarettes. Through the waist-shaped holes, the location of the popping bead inside the cigarette can be observed, and the flavor of the popping bead cigarette can be determined by observing the color of the location. In the actual production process of the aluminum foil used for popping bead cigarettes, it is necessary to use a cutting roller and a pressure roller to rotate relative to each other to cut and punch the aluminum foil during transmission.

One end of the side plate is connected to a distance adjustment assembly, and the other end is connected to the end of the pressure roller. The distance adjustment assembly is mounted on the frame. The above technical solution realizes the cutting operation of aluminum foil by counter-rotating the cutter roller and the pressure roller, and then using a waist-shaped cutter. At the same time, the steel roller and the rubber roller cooperate to achieve accurate guidance of the aluminum foil. A cross-shaped groove is provided on the rotating shaft and corresponds to the cross-shaped protrusion on the cutter plate, which can realize quick disassembly and precise positioning during operation. The inclination of the side plates can be changed by the distance adjustment assembly, thereby realizing the adjustment of the distance between the pressure roller and the cutter roller.

[0043] Example 1

[0044] Combined with attachment Figures 1 to 12This embodiment provides a device for cutting waist-shaped holes in aluminum foil, comprising a cutter roller 2 and a pressure roller 3 that rotate relative to each other to perforate aluminum foil. The cutter roller 2 comprises a rotating outer roller 21 and a fixed inner roller 22, which are sealed and rotatably sleeved. The rotating outer roller 21 is provided with a first waist-shaped hole 211, which is equipped with a waist-shaped cutter 212. The fixed inner roller 22 is provided with an inner roller cavity 222, with a second waist-shaped hole 221 at its top corresponding to the first waist-shaped hole 211. The inner roller cavity 222 is connected to a discharge pipe 24 connected to a waste paper bin 6. A suction mechanism 23 is provided within the inner roller cavity 222, which draws waste paper from the cutter 212 into the inner roller cavity 222, ultimately discharging it into the waste paper bin 6. In the above technical solution, the suction mechanism 23 can be any structure with a suction function, including but not limited to a vacuum pump or a fan, as long as it can generate a negative pressure within the inner roller cavity 222.

[0045] In a specific structure, the cutter roller 2 and the pressure roller 3 are mounted on a frame 1. The frame 1 is provided with a first motor 4 for driving the cutter roller 2 to rotate and a second motor 5 for driving the pressure roller 3 to rotate. The pressure roller 3 is located obliquely above the cutter roller 2. A pair of guide rollers 7 are provided upstream and downstream of the cutter roller 2 and the pressure roller 3, respectively. A third motor 8 drives the pair of guide rollers 7 to rotate. Aluminum foil paper is fed from below the abutment point between the cutter roller 2 and the pressure roller 3 and discharged from above the abutment point between the cutter roller 2 and the pressure roller 3. In the above technical solution, the pressure roller 3 is located obliquely above the cutter roller 2, that is, the two cut the aluminum foil paper at the abutment point obliquely above the cutter roller 2, which can prevent waste paper remaining in the cutter 212 from falling outside the cutter roller 2 after cutting.

[0046] In a specific structure, the rotating outer roller 21 has a circular outer roller cavity 213, one end of the rotating outer roller 21 is open and provided with an annular sealing cover 214, and the other end is provided with an outer roller shaft 215, the annular sealing cover 214 is sealed and rotatably connected to the fixed inner roller 22, and the outer roller shaft 215 is connected to the first motor 4; the fixed inner roller 22 has a rectangular inner roller cavity 222, one end of the fixed inner roller 22 is open and provided with a circular sealing cover 223, and the other end is provided with a connecting shaft 224, the circular sealing cover 223 is provided with an inner roller shaft 225, and the connecting shaft 224 is rotatably connected to the outer roller cavity 213 of the rotating outer roller 21.

[0047] The working principle and working process of this embodiment are as follows: the device is started, the suction mechanism 23 sucks the inner roller cavity 222 of the fixed inner roller 22, the rotating outer roller 21 and the pressure roller 3 of the cutter roller 2 rotate relative to each other, and the aluminum foil is punched and cut. When the cutting is completed, the waste paper enters the first waist-shaped hole 211 of the rotating outer roller 21 from the cutter 212, and the rotating outer roller 21 continues to rotate until it is connected with the second waist-shaped hole 221 above the fixed inner roller 22. The waste paper in the first waist-shaped hole 211 is sucked into the inner roller cavity 222 and then discharged from the discharge pipe 24 connected to the inner roller cavity 222 into the waste paper box 6, completing the collection of the waste paper.

[0048] In this embodiment, the cutter roller 2 cuts and punches aluminum foil and vacuum-sucks and stores waste paper by using the rotatable outer roller 21 and the fixed inner roller 22. On the one hand, this prevents waste paper generated during cutting and punching from adhering to the cutter 212 and affecting the normal cutting of the cutter 212, thereby improving cutting stability. On the other hand, this prevents the random scattering of waste paper and improves the cleanliness of the production environment.

[0049] Example 2

[0050] Combined with attachment Figures 1 to 12 This embodiment provides a device for cutting waist-shaped holes in aluminum foil. Based on Example 1, the structure of the inner roller cavity 222 is optimized to further improve the suction and discharge effect of waste paper. The specific technical solution is as follows:

[0051] The inner roller cavity 222 is sealed and separated from top to bottom by a partition group 25 into a suction cavity 2221 and a discharge cavity 2222. The partition group 25 includes an inclined partition 251, a reversible partition 252 and a horizontal partition 253. The inclined partition 251 is fixed at one end away from the circular sealing cover 223, the horizontal partition 253 is fixed at one end close to the circular sealing cover 223, and the reversible partition 252 is rotatably arranged between the inclined partition 251 and the horizontal partition 253. It is capable of rotating 180° under the control of the reversing drive mechanism 26. The second waist-shaped hole 221 is located above the inclined partition 251. The suction mechanism 23 is provided at one end of the suction chamber 2221 near the circular sealing cover 223. A push plate mechanism 27 is provided at one end of the discharge chamber 2222, away from the circular sealing cover 223, with the other end connected to the discharge pipe 24. The push plate mechanism 27 is capable of pushing waste paper in the discharge chamber 2222 into the discharge pipe 24. In the above technical solution, the inclined partition 251 facilitates the waste paper from sliding and collecting toward the reversible partition 252, preventing it from being left behind. When the reversible partition 252 is rotated under the control of the reversing drive mechanism 26, it can transport the waste paper accumulated in the suction chamber 2221 into the discharge chamber 2222. The push plate mechanism 27 then pushes the waste paper into the discharge pipe 24. The push plate mechanism 27 can adopt any structure with push-pull function, including but not limited to a cylinder with a rectangular push plate 271, which can push the waste paper into the discharge pipe 24 and can achieve reset.

[0052] The working principle and working process of this embodiment are as follows: the device is started, the suction mechanism 23 sucks the suction chamber 2221, the rotating outer roller 21 of the cutter roller 2 and the pressure roller 3 rotate relative to each other, punching and cutting the aluminum foil, and the cut waste paper enters the suction chamber 2221. After a certain cutting time (this time parameter is determined by the cutting speed and the volume of the suction chamber 2221), the flip drive mechanism 26 drives the flip partition 252 to quickly flip 180°. At this time, the waste paper in the suction chamber 2221 falls into the discharge chamber 2222. The push plate mechanism 27 pushes the waste paper in the discharge chamber 2222 into the discharge pipe 24, and the waste paper enters the waste paper box 6 through the discharge pipe 24.

[0053] Example 3

[0054] Combined with attachment Figures 1 to 12 This embodiment provides a device for cutting waist-shaped holes in aluminum foil. Based on Example 2, the structure of the suction mechanism 23 is optimized so that the suction mechanism 23 can directly convert the rotational force of the rotating outer roller 21 into a suction force. The specific technical solution is as follows:

[0055] The circular sealing cover 223 includes an inner circular cover 2231 and an outer circular cover 2232 that are arranged at intervals. The inner circular cover 2231 blocks the inner roller cavity 222. The outer circular cover 2232 is rotatably connected to the annular sealing cover 214. The inner roller shaft 225 passes through the outer circular cover 2232 and is fixedly connected to the inner circular cover 2231. The discharge pipe 24 seals and passes through the inner circular cover 2231 and the outer circular cover 2232.

[0056] In a specific structure, the suction mechanism 23 includes a ring gear 231, a large gear 232, a small gear 233 and an impeller 234. The ring gear 231 is fixed to the inner ring wall of the rotating outer roller 21. The large gear 232 meshing with the ring gear 231 and the small gear 233 meshing with the large gear 232 can be rotatably installed in the gap between the inner circular cover 2231 and the outer circular cover 2232. The rotating shaft seal of the small gear 233 can be rotatably passed through the inner circular cover 2231 and then connected to the impeller 234. The suction end of the impeller 234 is fixed with a filter plate 235 for blocking waste paper. An exhaust channel 226 is provided in the side wall of the fixed inner roller 22. One end of the exhaust channel 226 is connected to the exhaust end of the impeller 234, and the other end is connected to the discharge chamber 2222 away from the end of the discharge pipe 24.

[0057] The working principle and working process of this embodiment are as follows: the device is started, the rotating outer roller 21 of the cutter roller 2 and the pressure roller 3 rotate relative to each other, and the aluminum foil is punched and cut; the ring gear 231 on the rotating outer roller 21 is sequentially driven by the meshing transmission of the large gear 232 and the small gear 233 to increase the speed and then drive the impeller 234 to rotate. When the impeller 234 rotates, axial airflow is generated to achieve suction of the suction chamber 2221. The filter plate 235 blocks the waste paper approaching the impeller 234. The airflow at the exhaust end of the impeller 234 enters the discharge chamber 2222 through the exhaust channel 226, and the airflow is blown out from the end of the discharge chamber 2222 away from the discharge pipe 24 toward the discharge pipe 24. The airflow cooperates with the push plate mechanism 27 to send the waste paper into the discharge pipe 24, so that the waste paper is discharged more thoroughly.

[0058] Example 4

[0059] Combined with attachment Figures 1 to 12 This embodiment provides a device for cutting waist-shaped holes in aluminum foil. Based on Example 3, the structure of the flipping drive mechanism 26 is optimized to enable it to quickly perform a second flip and completely discharge the waste paper in the suction chamber 2221 into the discharge chamber 2222. The specific technical solution is as follows:

[0060] The flipping drive mechanism 26 includes a horizontal cylinder 261 fixed on the fixed inner roller 22, and a first bidirectional memory metal strip 262 and a first spring 264 are horizontally fixed in the horizontal cylinder 261. The first bidirectional memory metal strip 262 is connected to the wire and can extend when powered and heated, and shorten after the heating is stopped. The free ends of the first bidirectional memory metal strip 262 and the first spring 264 are connected to the sliding rod 263, and the sliding rod 263 can slide horizontally in the horizontal cylinder 261. The free end of the sliding rod 263 is provided with a thread groove 2631 (the thread is not shown). The flip partition 252 includes a partition body 2521, and the partition body 2521 is provided with a driving shaft 2522 at one end facing the sliding rod 263, and a driven shaft 2523 at the other end. The driving shaft 2522 is provided with a thread corresponding to the thread groove 2631 (not shown in the figure), and the driven shaft 2523 is rotatably connected to the horizontal partition 253. In the above technical solution, the horizontal guide sliding structure of the slide rod 263 in the horizontal cylinder 261 includes but is not limited to a guide sliding structure in which the slide groove and slider cooperate and a guide sliding structure in which the spline and the spline sleeve cooperate, which can ensure that the slide rod 263 slides linearly along the horizontal cylinder 261 without rotating.

[0061] In one specific configuration, sealing strips 2524 are provided on both sides of the partition body 2521 where it abuts the inner wall of the inner roller cavity 222. An annular gap is provided between the rotating outer roller 21 and the fixed inner roller 22. A connecting ring 28 is fixedly mounted on the outer annular wall of the fixed inner roller 22 and is rotatably and sealingly connected to the rotating outer roller 21. The connecting ring 28 is provided with a third waist-shaped hole 281 corresponding to the second waist-shaped hole 221. In the above technical solution, seals are preferably also provided at the abutment points between the partition body 2521 and the inclined partition 251 and the horizontal partition 253 to further enhance sealing. The annular gap between the rotating outer roller 21 and the fixed inner roller 22 reduces friction between them, concentrating friction on the rotating outer roller 21 and the connecting ring 28, which have a smaller contact area.

[0062] The working principle and working process of this embodiment are as follows: when the reversible partition 252 needs to be reversed, the first two-way memory metal strip 262 is electrically heated to raise its temperature above the deformation temperature, the first two-way memory metal strip 262 extends, and pushes the slide bar 263 to move toward the driving shaft 2522 of the reversible partition 252. The first spring 264 is stretched, accumulating elastic force, and the driving shaft 2522, which is threadedly engaged with the thread groove 2631 of the slide bar 263, rotates rapidly 180 degrees under the drive of the thread, driving the reversible partition 252. The driving shaft 2522 drives the partition body 2521 to quickly flip once. After the first flip is completed, the heating of the first two-way memory metal strip 262 is stopped to reduce its temperature below the deformation temperature. The first two-way memory metal strip 262 shortens, and the first spring 264 pulls the slide bar 263 to return to its original position. The driving shaft 2522 rotates 180 degrees again, driving the partition body 2521 to quickly flip a second time. After two rapid flips, all the waste paper in the suction chamber 2221 can be discharged into the discharge chamber 2222.

[0063] Example 5

[0064] Combined with attachment Figures 1 to 12 This embodiment provides a device for cutting waist-shaped holes in aluminum foil. Based on Example 4, the structure of the push plate mechanism 27 is optimized to further improve the discharge efficiency of waste paper. The specific technical solution is as follows:

[0065] The push plate mechanism 27 includes a rectangular push plate 271 that can slide horizontally along the discharge chamber 2222. An air chamber 2711 is provided inside the rectangular push plate 271, and a plurality of air outlet holes 2712 are provided at one end facing the discharge pipe 24, and the other end is respectively connected to the push plate driving mechanism 272 and the telescopic tube 273. One end of the telescopic tube 273 is sealed and connected to the exhaust channel 226, and the other end is sealed and connected to the air chamber 2711. The push plate driving mechanism 272 includes a hydraulic cylinder 2721, and a piston 2722 is provided in the hydraulic cylinder 2721. One end of the piston 2722 is connected to a second bidirectional memory metal strip 2723 and a second spring 2724, and the other end is filled with pressurized liquid and connected to a horizontal sealed telescopic sleeve 2725. The free end of the sealed telescopic sleeve 2725 is connected to the rectangular push plate 271. The second bidirectional memory metal strip 2723 is connected to a wire and can extend when powered on and heated, and shorten after heating is stopped. In the above technical solution, the telescopic tube 273 can be a soft bellows or a telescopic sleeve structure, as long as it can adapt to the displacement of the rectangular push plate 271.

[0066] The working principle and working process of this embodiment are as follows: when it is necessary to discharge waste paper, the second two-way memory metal strip 2723 is electrically heated to raise its temperature above the deformation temperature, the second two-way memory metal strip 2723 extends, pushing the piston 2722 upward, the second spring 2724 is stretched, accumulating elastic force, the pressure liquid in the hydraulic cylinder 2721 continuously enters the sealed telescopic sleeve 2725, and drives the sealed telescopic sleeve 2725 to continuously extend, at the same time, the air flow in the exhaust channel 226 enters the air cavity 2711 of the rectangular push plate 271 through the telescopic tube 273, and is discharged from the exhaust channel 226. The airflow from the air outlet holes 2712, combined with the push of the rectangular push plate 271, can quickly and completely discharge the waste paper in the discharge chamber 2222 into the discharge pipe 24. After the waste paper is completely discharged, the heating of the second two-way memory metal strip 2723 is stopped to reduce its temperature below the deformation temperature. The second two-way memory metal strip 2723 contracts, and the second spring 2724 pulls the piston 2722 to return to its original position. The pressurized liquid in the sealing telescopic sleeve 2725 returns to the hydraulic cylinder 2721 under the action of negative pressure. The sealing telescopic sleeve 2725 contracts, driving the rectangular push plate 271 to return to its original position.

[0070] Step S200: After cutting is completed, the waste paper enters the first waist-shaped hole 211 of the rotating outer roller 21 through the cutter 212. The rotating outer roller 21 continues to rotate until it connects with the second waist-shaped hole 221 above the fixed inner roller 22. The waste paper in the first waist-shaped hole 211 is sucked into the inner roller cavity 222.

[0071] Step S300: After a certain period of cutting time, the waste paper in the inner roller cavity 222 is discharged from the discharge pipe 24 into the waste paper box 6, completing the collection of the waste paper.
