Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing technology, and in particular to a method for stabilizing negative pressure in a forming machine to reduce wrinkles on the appearance of filter rods. Background Technology

[0002] During the assembly and forming process of the cigarette tobacco section and filter section, the filter tip assembly machine is equipped with several sets of rotating drums, including filter rod cutting drums, merging drums, approaching drums, and twisting drums. The filter rod enters the filter rod cutting drum from the hopper, is cut into filter tip segments that match the length of the filter tip, and is then transferred to the merging drum. The merging drum combines two cigarettes from the cigarette rolling machine with the filter tip segments to form an assembly, which is then transferred to the approaching drum. On the approaching drum, the cigarettes at both ends of the filter tip segment are pressed together by a float ring structure to eliminate gaps and form a cigarette assembly. When the cigarette assembly is transferred to the merging drum, the glued tipping paper is simultaneously fed to the merging drum, wrapping the tipping paper around the assembly to form a filter cigarette.

[0003] The announcement number is CN110771950B, and the name is a cigarette capsule filling device. It describes that: "It includes a conveyor belt, a capsule filling mechanism, a cigarette limiting mechanism and a position adjustment mechanism. The conveyor belt is provided with several limiting strips. The capsule filling mechanism includes a worktable, a capsule pushing assembly and two capsule conveying assemblies. Each capsule conveying assembly includes a capsule conveying hollow needle, a capsule storage assembly and an installation tube. Each capsule conveying hollow needle is provided with a capsule pushing rod that slides with it."

[0004] However, during the processing of the above-mentioned device, when the popping beads are injected into the filter rod to enhance the flavor of the cigarette by relying on the push bead assembly and the conveying bead assembly, the injection action will cause radial compression on the filter rod. The resulting deformation is prone to forming wrinkles or protrusions on the surface of the filter rod, thereby reducing the quality of the final product. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a molding machine that reduces wrinkling defects in the appearance of filter rods. The machine transports a cigarette without a filter and a filter core, which are secured by connecting paper, to a ball-throwing assembly via a conveying component. The ball-throwing assembly precisely segments the filter core and connecting paper, and then places a fragrance ball between the two filter core segments. The machine is then wrapped with transparent paper by a limiting component and an upper lifting component. This solves the problem in existing technologies where adding cigarette flavor causes radial compression to the filter core, resulting in wrinkles or bulges.

[0006] To address the above technical issues, the following technical solution is adopted: A forming machine for reducing wrinkles on the appearance of filter rods includes a fragrance ball processing mechanism.

Preferably, the pitching assembly includes: A cutter, which is rotatably positioned above the conveyor belt; A separator, which is mounted on the side of the cutter; A ball cylinder, which is mounted on top of the separation frame; The ball-distributing plate is rotatably disposed inside the ball cylinder and works in conjunction with a baffle plate installed inside the ball cylinder to achieve the action of discontinuously distributing incense balls; A temporary storage tube is installed at the bottom of the baffle plate, and the bottom end of the temporary storage tube is connected to the separation frame; The pitching disc, which is rotatably disposed inside the separating frame; and A wrapping roller is rotatably mounted on the side of the ball cylinder.

[0009] Preferably, the limiting component includes: A clamping rod, which is rotatably disposed inside the receiving seat; The sliding rod is slidably disposed inside the receiving seat, and cooperates with the lifting rod installed on both sides of it and slidably disposed inside the clamping rod to drive the clamping rod to rotate. A fixed housing, which is installed inside the receiving seat; A retaining ball is elastically slidably disposed inside the sliding rod, and works in conjunction with a retaining groove opened inside the fixed shell to achieve the limiting action of the sliding rod; A protrusion, wherein the protrusion is disposed on the side of the sliding rod; and An arc-shaped plate is elastically slidably disposed inside the receiving seat.

[0010] Preferably, the top component includes: A connecting plate, which is vertically and vertically mounted on the side of the conveyor belt; Top column, the top column being vertically and elastically slidably mounted on the connecting plate; and A top plate, which is mounted on top of a connecting plate and is adapted to the curved plate.

[0011] Preferably, the adhesive application assembly includes: A feeding shaft is rotatably mounted above the conveyor belt; Tension roller, which is rotatably mounted on the side of the feeding shaft; A glue box, which is mounted on the side of the tension roller; The first rubber roller is rotatably disposed inside the rubber box; The second rubber roller is rotatably fitted and positioned above the first rubber roller; The pressing roller is rotatably mounted above the second rubber roller and drives the first rubber roller, the second rubber roller, and the pressing roller to rotate synchronously via a first transmission unit; and A support roller is rotatably mounted above the feeding shaft.

[0012] Preferably, the cutting assembly includes: A paper cutting wheel, which is rotatably positioned above the conveyor belt; A cutter roller, rotatably mounted on the side of a paper cutting wheel; and A converging drum is rotatably positioned below the paper cutting wheel, and the paper cutting wheel, the cutter roller, and the converging drum rotate synchronously through a second transmission unit.

[0013] Preferably, the transparent paper mounting assembly includes: A lifting frame, which is vertically and vertically positioned below the receiving seat; Material rollers, which are rotatably mounted on both sides of the lifting frame; A steering roller, which is rotatably disposed between the material rollers; A suction cup, said suction cup being mounted on the top of the lifting frame; and A push rod is mounted on the ball-distributing plate and is adapted to the sliding rod.

[0014] As a preferred embodiment, a negative pressure stabilization control method for reducing wrinkles on the appearance of filter rods includes the following steps: S1. Preliminary cigarette assembly process: The gluing component applies glue to the surface of the tipping paper, and then the cutting component cuts the glued tipping paper into connecting paper for transfer. The negative pressure pipes of the converging drum and the paper cutting wheel of the cutting component are connected to the centralized process wind power dust removal system. The converging drum adsorbs the cigarettes without filter and transports them to the conveying component after they are attached to the connecting paper. S2, Connecting paper wrapping process: When the cigarette without a filter and the filter fall onto the conveying component, the connecting paper is wrapped in a semi-circular shape. Then, the negative pressure air box of the wrapping component absorbs the unwrapped part of the connecting paper and moves with it to flatten and wrap it on the cigarette without a filter and the filter. Then, the wrapping component rotates the cigarette without a filter and the filter to complete the wrapping of the connecting paper. S3, Beading Process: After the beading component cuts and precisely separates the filter and connecting paper, it places a bead between the two filter sections. Then, the top component, in conjunction with the limiting component, releases the restriction on the transparent paper and pushes the transparent paper to the outside of the connecting paper. The transparent paper is then wrapped, and the cigarette processing is completed. S4. Transparent paper loading process: The transparent paper loading component pushes the transparent paper into the conveying component and relies on the limiting component to limit the transparent paper.

[0015] The beneficial effects of this invention are: (1) The present invention transports the cigarette without a mouthpiece and the filter core, which are fixed by the connecting paper, to the ball throwing component through the conveying component. The ball throwing component performs precise spacing after cutting the filter core and the connecting paper, and then puts the incense ball between the two filter cores. The transparent paper is wrapped by the limiting component and the top component, which reduces the occurrence of wrinkles and protrusions in the filter core due to compression. The precise spacing ensures high consistency of cigarette production length.

[0016] (2) In this invention, the transparent paper can be clamped by the limiting component to avoid bending and shifting of the transparent paper during the conveying process. In the process of the upper component pressing the limiting component once, the restriction on the transparent paper is released first, and then the transparent paper is initially wrapped around the outside of the connecting paper, which simplifies the structure and improves the production cycle. The initial wrapping of the transparent paper on the filter element reduces the change in the distance between the two filter elements during the subsequent filter element transfer and before the transparent paper is completely wrapped. In addition, when the transparent paper is initially wrapped around the filter element, the inner wall of the receiving seat limits the edge of the transparent paper, which reduces the serious shift of the transparent paper during the process of being squeezed and wrapped by the arc plate, and ensures the stability of cigarette processing.

[0017] (3) In this invention, the filter core and connecting paper are cut by the ball-throwing component using a rotating cutter, which reduces the compression of the filter core during the cutting process. The ball-throwing component can accurately throw the incense ball individually, avoiding the situation where there is no incense ball or too many incense balls in the cigarette, thus ensuring the yield of cigarette production.

[0018] (4) In this invention, the wrapping component first uses negative pressure to adsorb the part of the connecting paper that is not yet wrapped in the cigarette without a filter. As the conveying component moves the cigarette without a filter and the filter relative to the wrapping component, the part of the connecting paper that is not wrapped is stretched and flattened and then covered and wrapped. Then the cigarette without a filter and the filter are rolled at the same time to completely wrap the cigarette. This reduces the occurrence of wrinkles in the wrapping of the connecting paper and reduces the occurrence of wrinkles caused by the relative rotation of the cigarette without a filter and the filter. This improves the yield of cigarettes.

[0019] In summary, this equipment has the advantages of high yield, stable processing, and high consistency in cigarette production. Attached Figure Description

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1 like Figures 1 to 6 As shown, a forming machine for reducing wrinkles on the appearance of filter rods includes: The incense ball processing mechanism 1 includes a conveying assembly 11 for conveying a cigarette without a filter 31, a filter core 32, and a connecting paper 33; a wrapping assembly 12 disposed above the conveying assembly 11 for smoothing and wrapping the connecting paper 33 around the cigarette without a filter 31 and the filter core 32; a ball-throwing assembly 13 disposed above the conveying assembly 11 for precisely cutting the filter core 32 to create gaps and placing incense balls 35 into the gaps; a limiting assembly 14 disposed inside the conveying assembly 11 for limiting and mounting transparent paper 34; and a top-mounting assembly 15 disposed on the side of the conveying assembly 11. The upper assembly 2 is located around the incense ball processing mechanism 1. It includes an adhesive application assembly 21 located above the conveying assembly 11, a cutting assembly 22 located on the side of the adhesive application assembly 21, and a transparent paper upper assembly 23 located below the conveying assembly 11.

[0035] It is worth mentioning that the cigarette 3 includes a filterless cigarette 31. A filter 32 is attached to the end of the filterless cigarette 31. Another filter 32 is arranged at an interval at the end of the filter 32 away from the filterless cigarette 31. The outer side of the filterless cigarette 31 near the filter 32 and the adjacent filter 32 are connected by a connecting paper 33. The outer side of the filter 32 away from the filterless cigarette 31 is wrapped with a connecting paper 33. The outer side of the two connecting papers 33 that are close to each other is connected by a transparent paper 34. A fragrance ball 35 is arranged inside the transparent paper 34. Preferably, the aroma ball 35 has an annular groove on its exterior. The design of the annular groove increases the surface area of ​​the aroma ball 35, allowing more smoke to come into contact with the aroma ball 35 before being inhaled by the user, thereby increasing the concentration of flavor in the smoke. Preferably, the inner wall of the transparent paper 34 is provided with ribs. When the transparent paper 34 is laid flat, the ribs are elongated ribs, and when the transparent paper 34 is wrapped around the two sections of transparent paper 34, the ribs are semi-circular ribs. When the user smokes, the ribs downward restrict the incense ball 35 to be close to the tobacco end. The incense ball 35 is fixed at the smoke inlet. When the high-temperature and high-humidity smoke enters the filter from the tobacco section, it must pass through / around the incense ball 35 to continue. The smoke and the incense ball 35 are in forced, sufficient and long-term contact, which is highly efficient. Extracting the flavoring components produces a smoke with a full aroma and rich smoke, but with greater draw resistance. When the ribs are facing upwards, the aroma ball 35 can roll back and forth within the transparent paper 34 without being restricted by the ribs. When inhaling, it may be drawn towards the filter tip or remain in the middle due to gravity. The smoke can pass smoothly through the gap between the ball and the filter wall. The smoke does not come into full contact with the aroma ball and mainly relies on the small amount of aroma that is volatilized to mix, resulting in a smoke with a smooth smoke and light aroma, which is closer to traditional cigarettes. The two smoking methods meet the diverse needs of users. The aroma capsule 35 is a solid porous flavoring body that does not contain liquid flavoring. It can continuously release its aroma as airflow passes through without needing to be broken by external force. Compared with traditional liquid flavoring capsules, the aroma capsule 35 of this application will not release a large amount of flavoring instantly due to breakage, thus masking the natural aroma of tobacco, and also avoids the risk of liquid soaking the filter rod material.

[0036] It should be noted that the forming machine for reducing wrinkles in the appearance of filter rods in this embodiment also includes a frame and a drive mechanism. The incense ball segment processing mechanism 1 and the upper assembly mechanism 2 are respectively installed on the frame. The drive mechanism consists of a vacuum generator, an electric telescopic rod, a hydraulic rod, a telescopic cylinder, and several servo motors. The negative pressure pipe of the converging drum 223, the paper cutting wheel 221, and the negative pressure air box 121 is connected to the centralized process wind power dust removal system. The forming machine for reducing wrinkles in the appearance of filter rods also includes a host computer controller to control the operation of various components. The frame, drive mechanism, and controller are common knowledge to those skilled in the art and will not be described in detail here.

[0037] In this embodiment, preferably, such as Figures 1 to 4 As shown, the transmission component 11 includes: Conveyor belt 111, on which multiple receiving seats 112 for receiving cigarettes 3 are installed; Limit frame 113, limit frame 113 is installed above conveyor belt 111; and The receiving box 114 is installed below the conveyor belt 111.

[0038] Package component 12 includes: Negative pressure air box 121, which is installed above the conveying assembly 11; and Friction roller shaft 122 is rotatably mounted on the side of negative pressure air box 121.

[0039] Furthermore, the top of the receiving seat 112 is provided with a groove for receiving cigarettes 3. The groove is open at both ends, and the lengths of the cigarette without a mouthpiece 31 and the filter 32 are adapted to the length of the groove. With the help of the vertical plates of the limiting frame 113 located at both ends of the receiving seat 112, the cigarette without a mouthpiece 31 and the filter 32 falling into the receiving seat 112 can be accurately limited, ensuring the accuracy of the subsequent ball-throwing assembly 13 cutting position of the filter 32.

[0040] In addition, a through hole is provided on the side of the negative pressure box 121 away from the friction roller shaft 122. The negative pressure inside the negative pressure box 121 can be used to attract the corresponding connecting paper 33 through the through hole. As the receiving seat 112 moves relative to the negative pressure box 121 carrying the cigarette without a mouthpiece 31, the filter 32 and the connecting paper 33, the adsorption force of the negative pressure box 121 on the connecting paper 33 can flatten it and cover it above the cigarette without a mouthpiece 31 and the filter 32, thus avoiding wrinkles when the connecting paper 33 is wrapped.

[0041] It is worth mentioning that the negative pressure generated by the negative pressure box 121 causes the connecting paper 33 to move along with the receiving seat 112 and stick to the outside of the negative pressure box 121. However, the negative pressure is not enough to pull the cigarette without a mouthpiece 31 and the filter 32 out of the receiving seat 112 through the connecting paper 33. Furthermore, the cutting assembly 22, with the cigarette 31 tightly attached to the end of the filter element 32 and the connecting paper 33 pasted on the outside of the filter element 32 and below the side of the cigarette 31 near the filter element 32, places the three assemblies onto the receiving seat 112. The two vertical plates of the limiting frame 113 restrict their position on the receiving seat 112. Subsequently, the cigarette 31 and the filter element 32 fall into the receiving seat 112. The connecting paper 33 is restricted by the inner wall of the receiving seat 112, so that the connecting paper 33 automatically wraps the lower part of the cigarette 31 and the filter element 32. The drive mechanism controls the conveyor belt 111 to run, causing the receiving seat 112 to move the cigarette without a filter 31, the filter 32, and the connecting paper 33 closer to the wrapping assembly 12. During the process, the unwrapped connecting paper 33 is attracted by the negative pressure released from the side of the negative pressure box 121. As the receiving seat 112 moves, the connecting paper 33 is stretched and smoothed by the negative pressure box 121 and covers the cigarette without a filter 31 and the filter 32. Then, the cigarette without a filter 31 and the filter 32 come into contact with the friction roller shaft 122 driven by the drive mechanism through the connecting paper 33. The friction roller shaft 122 drives the cigarette without a filter 31 and the filter 32 to rotate in the receiving seat 112, thereby completing the wrapping of the cigarette without a filter 31 and the filter 32 by the connecting paper 33.

[0042] Preferred, such as Figures 2 to 8 As shown, the pitching assembly 13 includes: Cutter 131 is rotatably positioned above conveyor belt 111; Separator 132, which is mounted on the side of cutter 131; Ball cylinder 133 is mounted on top of separator 132; The ball-distributing plate 134 is rotatably disposed inside the ball tube 133 and works in conjunction with the baffle plate 135 installed inside the ball tube 133 to achieve the action of discontinuously distributing the incense balls 35. Temporary storage tube 136 is installed at the bottom of baffle plate 135, and the bottom end of temporary storage tube 136 is connected to separation frame 132. The pitching plate 137 is rotatably mounted inside the separator 132; and The wrapping roller 138 is rotatably mounted on the side of the ball cylinder 133.

[0043] Limiting component 14 includes: Clamping rod 141 is rotatably disposed inside the receiving seat 112; The sliding rod 143 is slidably disposed inside the receiving seat 112, and cooperates with the lifting rod 142, which is installed on both sides of the receiving seat and slidably disposed inside the clamping rod 141, to drive the clamping rod 141 to rotate. The fixing housing 144 is installed inside the receiving seat 112; The ball 145 is elastically slidably disposed inside the sliding rod 143, and works with the slot opened inside the fixed shell 144 to realize the limiting action of the sliding rod 143; Protrusion 146, protrusion 146 is provided on the side of sliding rod 143; and The arc-shaped plate 147 is elastically slidably disposed inside the receiving seat 112.

[0044] Top component 15 includes: Connecting plate 151 is vertically and vertically mounted on the side of conveyor belt 111; Top column 152, the top column 152 is vertically and elastically slidably mounted on the connecting plate 151; and Top plate 153 is installed on top of connecting plate 151 and is adapted to arc plate 147.

[0045] Preferably, the ball-distributing plate 134 and the ball-throwing plate 137 are driven to rotate by the same rotating axis, reducing the number of drive sources required and lowering the manufacturing cost of the device. Simultaneously, the ball-throwing plate 137 has holes that allow the incense balls 35 to rotate within the separating frame 132 to achieve the purpose of distributing the incense balls 35. The edge of the ball-distributing plate 134 has semi-circular grooves for carrying the incense balls 35 to the top of the temporary storage tube 136. The number of semi-circular grooves in a uniform annular array on the ball-distributing plate 134 should be greater than the number of holes in a uniform annular array on the ball-throwing plate 137. That is, when the ball-throwing plate 137 completes one distribution of incense balls 35, the number of semi-circular grooves in the ball-distributing plate 134 passing above the temporary storage tube 136 should be greater than one. This ensures that, assuming there are no shortage of incense balls 35 in the ball cylinder 133, there are always continuously vertically stacked incense balls 35 inside the temporary storage tube 136 during the coaxial rotation of the ball-distributing plate 134 and the ball-throwing plate 137, thus ensuring the stability of cigarette processing.

[0046] Furthermore, the clamping rod 141 can clamp the transparent paper 34 to prevent it from falling or becoming misaligned during the transfer of the transparent paper 34 with the receiving seat 112, thus ensuring the accuracy of the position of the transparent paper 34 in the subsequent loading.

[0047] In addition, the curved plate 147 can attach part of the transparent paper 34 to the two filter cores 32, so that the transparent paper 34 forms a partial recessed groove, which can temporarily support the incense ball 35 and reduce the possibility that the incense ball 35 will fall off accidentally when the transparent paper 34 is not completely wrapped and the receiving seat 112 is conveyed.

[0048] It is worth mentioning that the transparent paper 34 is initially provided with adhesive on the side away from the curved plate 147 and near the length edge. The adhesive part corresponds to the position of the two filter elements 32 close to each other at one end. The area with the greatest thickness of the separating frame 132 is equal to the thickness of the gap between the filter elements 32 after final cutting and spacing. Therefore, when the transparent paper 34 is partially attached to the two filter elements 32 on the curved plate 147, the transparent paper 34 will not stick to the separating frame 132, ensuring the stability of cigarette processing.

[0049] Furthermore, the drive mechanism controls the conveying assembly 11 to move the cigarette 31 without a mouthpiece and the filter 32 wrapped by the connecting paper 33 towards the direction of the throwing assembly 13. During the process, the drive mechanism controls the cutter 131 to rotate and cut the connecting paper 33 and the filter 32 wrapped inside it. As the movement continues, the separating frame 132 extends between the two filter 32 sections. As the receiving seat 112 moves, the distance between the two filter 32 sections gradually increases. During this process, the distance between the two corresponding vertical plates of the limiting frame 113 also gradually increases, thereby limiting the filter 32 and the end of the cigarette 31 without a mouthpiece. When the gap between the two filter elements 32 moves to the outlet at the bottom of the separating frame 132, the drive mechanism controls the connecting plate 151 to rise, which in turn drives the top column 152 to squeeze the sliding rod 143. The elastic force on the top column 152 pushes the sliding rod 143 upward, causing the protrusion 146 to move upward to contact the inner wall of the receiving seat 112. The corresponding locking ball 145 is then engaged in the corresponding groove above the fixed shell 144. During this process, the lifting rod 142 moves upward, causing the clamping rod 141 to rotate, thereby releasing the squeezing of the transparent paper 34. During the pressure restriction process, the top plate 153 also pushes the arc plate 147 to contact the transparent paper 34. Then the connecting plate 151 continues to move upward. The arc plate 147, pressing against the transparent paper 34, is pasted to the outside of the two connecting papers 33 under the restriction of the inner wall of the receiving seat 112. During the process, the horizontal plate of the limiting frame 113 limits the cigarette without a mouthpiece 31 and the filter 32 to prevent them from moving upward and detaching from the receiving seat 112. The part of the transparent paper 34 without adhesive in the middle is affected by the separating frame 132, causing the corresponding area to bend. The drive mechanism controls the rotation of the ball-throwing plate 137 and the ball-distributing plate 134. The ball-throwing plate 137 rotates a scent ball 35 inside the temporary storage tube 136 to the bottom outlet of the corresponding separation frame 132. The scent ball 35 then falls between the two filter elements 32 and is located on the transparent paper 34. During this process, the rotation of the ball-distributing plate 134 carries multiple scent balls 35 over the temporary storage tube 136 to replenish the scent balls 35 inside the temporary storage tube 136. Subsequently, the receiving seat 112 moves with the cigarette without a mouthpiece 31. After the wrapping roller 138 contacts the cigarette without a mouthpiece 31 and the connecting paper 33, it causes them to roll, thereby wrapping the transparent paper 34 around the two sections of connecting paper 33. Then, the drive mechanism rotates the receiving seat 112. When the receiving seat 112 tilts and gradually becomes vertical, the cigarette 3 inside falls into the receiving box 114 and is collected.

[0050] Furthermore, such as Figures 9 to 10 As shown, the adhesive application assembly 21 includes: The feeding shaft 211 is rotatably positioned above the conveyor belt 111; Tension roller 212 is rotatably mounted on the side of feeding shaft 211; Glue box 213 is installed on the side of tension roller 212; The first rubber roller 214 is rotatably disposed inside the rubber box 213; The second rubber roller 215 is rotatably attached to the top of the first rubber roller 214; Press roller 216 is rotatably positioned above second rubber roller 215, and drives first rubber roller 214, second rubber roller 215, and press roller 216 to rotate synchronously via first transmission unit; and Support roller 217 is rotatably positioned above the feeding shaft 211.

[0051] Cutting assembly 22 includes: Paper cutting wheel 221 is rotatably positioned above conveyor belt 111; Cutting roller 222, the cutting roller 222 is rotatably mounted on the side of the paper cutting wheel 221; and The converging drum 223 is rotatably positioned below the paper cutting roller 221, and the paper cutting roller 221, the cutter roller 222, and the converging drum 223 rotate synchronously through the second transmission unit.

[0052] Furthermore, the first transmission unit includes transmission gears 218 respectively installed at the ends of the second rubber roller 215 and the pressing roller 216, and sprockets 219 respectively installed at the ends of the second rubber roller 215 and the first rubber roller 214. The two transmission gears 218 are meshed with each other, and the two sprockets 219 are connected by chain transmission.

[0053] In this embodiment, preferably, the second transmission unit includes a small gear 224 installed at the ends of the paper cutting roller 221 and the cutter roller 222 respectively, and a large gear 225 installed at the end of the converging drum 223. The two small gears 224 are meshed with each other, and one of the small gears 224 is meshed with the large gear 225. It is worth mentioning that this application should also be used in conjunction with a production drum assembly in actual use. The production drum assembly includes a drum that serves to bring the cigarette without a mouthpiece 31 and the filter element 32 together and close them. The negative pressure pipe in the production drum assembly is connected to the centralized process air dust removal system. The drum assembly delivers the aligned cigarette without a mouthpiece 31 and the filter element 32 to the converging drum 223, which is prior art well known to those skilled in the art, and therefore will not be described in detail.

[0054] Furthermore, the drive mechanism controls the pressing roller 216 to rotate, which drives the second glue roller 215 to rotate through two meshing transmission gears 218. The second glue roller 215 drives the first glue roller 214 to rotate through two sprockets 219 and a matching chain. The rotation of the first glue roller 214 causes the glue in the glue box 213 to cover it. The second glue roller 215 rotates in close contact with the first glue roller 214, simultaneously covering the second glue roller 215 with a relatively thinner and more even layer of glue on the first glue roller 214. The rotation between the second glue roller 215 and the pressing roller 216 pulls the cork paper on the feeding shaft 211 to spread around multiple tension rollers 212 and apply glue. The drive mechanism drives the paper cutting wheel 221 to rotate, and at the same time drives the cutter roller 222 to rotate through two meshing small gears 224. The large gear 225 drives the converging drum 223 to rotate. After the water-filled paper coated with glue is attached to the paper cutting wheel 221, the centralized process wind dust removal system and negative pressure pipeline drive the paper cutting wheel 221 and the converging drum 223 to generate negative pressure. The negative pressure on the paper cutting wheel 221 adsorbs the water-filled paper, and after being cut by the cutter roller 222, it forms the connecting paper 33. Subsequently, the paper cutting roller 221 adsorbs the connecting paper 33 and transfers it to the top of the converging drum 223 to release the adsorption. At the same time, the production drum assembly conveys the nearby filterless cigarette 31 and filter 32 to the converging drum 223. When the converging drum 223 carries the filterless cigarette 31 and filter 32 over the paper cutting roller 221, the connecting paper 33 is attached at the connection between the two. The corresponding connecting paper 33 is then detached from the paper cutting roller 221.

[0055] In this application, as Figures 11 to 12 As shown, the transparent paper mounting component 23 includes: The lifting frame 234 is vertically lifted and positioned below the receiving seat 112; Material rollers 231 are rotatably mounted on both sides of the lifting frame 234; The steering roller 232 is rotatably disposed between the material rollers 231; Suction cup 235 is mounted on top of lifting frame 234; and The push rod 236 is mounted on the ball distribution plate 134 and is adapted to the sliding rod 143.

[0056] Furthermore, the two rollers 231 are used to place the raw material roll of transparent paper 34 and the waste roll of transparent paper 34, respectively. In addition, the raw material roll of transparent paper 34 includes the waste roll of transparent paper 34 and transparent paper 34 installed on the waste roll of transparent paper 34 through the easy-tear line 233. The easy-tear line 233 facilitates the use of transparent paper 34.

[0057] Furthermore, the drive mechanism rotates the material roller 231, pulling the raw material roll of transparent paper 34, along with the waste roll of transparent paper 34, to move accordingly. The easy-tear line 233 on the raw material roll of transparent paper 34 stops after aligning with the lifting frame 234. When the receiving seat 112 moves to the corresponding easy-tear line 233, the transparent paper 34 inside is consumed during production. Subsequently, the drive mechanism controls the lifting frame 234 to rise, thereby adsorbing the corresponding transparent paper 34 and removing it from the raw material roll of transparent paper 34 in conjunction with the easy-tear line 233. After removal, it remains in an adsorbed state. Then it rises further, so that the edge of the transparent paper 34 is higher than the lowest point of the pressing part of the clamping rod 141, and after the top rod 236 contacts the sliding rod 143 through the transparent paper 34, it further controls the lifting frame 234 to rise. The top rod 236 makes the lowest point of the sliding rod 143 flush with the corresponding shell wall of the receiving seat 112. As the sliding rod 143 rises, the lifting rod 142 drives the clamping rod 141 to rotate and restrict the pressing of the transparent paper 34. Then the suction cup 235 releases the adsorption of the transparent paper 34, and the lifting frame 234 is reset.

[0058] Example 2 like Figures 1 to 12 As shown, a negative pressure stabilization control method for reducing wrinkles on the appearance of filter rods includes the following steps: S1. Preliminary cigarette assembly process: The gluing component 21 applies glue to the surface of the tipping paper, and then the cutting component 22 cuts the glued tipping paper into connecting paper 33 for transfer. The negative pressure pipes of the converging drum 223 and the paper cutting wheel 221 of the cutting component 22 are connected to the centralized process wind power dust removal system. The converging drum 223 adsorbs the cigarette without a mouthpiece 31 and the filter 32 and transports them to the conveying component 11 after they are attached to the connecting paper 33. S2, Connecting paper wrapping process: When the cigarette without a mouthpiece 31 and the filter 32 fall onto the conveying component 11, the semi-circular wrapping of the connecting paper 33 is completed. Then, the negative pressure air box 121 of the wrapping component 12 absorbs the unwrapped part of the connecting paper 33 and flattens it as it moves to wrap the cigarette without a mouthpiece 31 and the filter 32. Then, the wrapping component 12 rotates the cigarette without a mouthpiece 31 and the filter 32 to complete the wrapping of the connecting paper 33. S3, Beading process: After the beading component 13 cuts and precisely separates the filter element 32 and the connecting paper 33, it puts a fragrance ball 35 between the two filter elements 32. Then, the top component 15, together with the limiting component 14, releases the restriction on the transparent paper 34 and pushes the transparent paper 34 to the outside of the connecting paper 33. Then, the transparent paper 34 is wrapped, and the processing of cigarette 3 is completed. S4. Transparent paper loading process: The transparent paper loading component 23 pushes the transparent paper 34 into the inside of the conveying component 11, and the limiting component 14 limits the transparent paper 34.
