Description

Technical Field

[0001] The invention belongs to the technical field of cigarette paper production and processing, and particularly relates to a preparation device for bidirectional moisture-retaining cigarette paper. Background Art

[0002] Enhancing the flavor and retaining the moisture as well as reducing the harm and tar of cigarettes is a comprehensive technology. In addition to adjusting the formula of cigarette leaf groups, the use of appropriate cigarette auxiliary materials, especially the modification and application of existing cigarette paper (including tipping paper, cigarette paper, paper filter rods, etc.), reflects the technical content and differentiated personality of the product, which is one of the effective ways to meet market demand.

[0003] Cigarette paper is one of the important auxiliary materials in cigarette production. It is directly involved in cigarette combustion and has a very important impact on the burning speed of cigarettes, the release of harmful components in mainstream smoke, the taste of smoking and the appearance of cigarette products. In addition, the moisture content in mainstream cigarette smoke is also an important indicator affecting the sensory comfort of cigarettes, which directly affects the intrinsic quality of cigarettes. When the moisture content of smoke is appropriate, the smoke is soft and delicate, less irritating, and has good sensory comfort. When the moisture content of smoke is too low, it will cause the smoke to be dry, irritating, and reduce sensory comfort.

[0004] For example, CN107460776B discloses a method for preparing moist ash-retaining cigarette paper, which comprises adding phosphoric acid and sodium dodecylbenzene sulfonate to a calcium hydroxide solution in sequence, stirring and aging, and then separating the solid and the liquid, taking the solid and calcining it to obtain calcium hydroxyphosphate; then mixing and pulping the calcium carbonate, calcium hydroxyphosphate and papermaking fibers to obtain a slurry; dehydrating, shaping, pressing and copying the slurry into a wet paper shape, and then adding an auxiliary agent into the paper by sizing, and then drying, rolling and cutting to obtain the moist ash-retaining cigarette paper; when in use, the auxiliary agent needs to be added in the papermaking process to obtain the moist ash-retaining cigarette paper. For existing paper that has been produced, when it needs to be processed, based on this, CN103469691A discloses a method for preparing natural tobacco leaf textured cigarette paper, in which a coating liquid is prepared during use, the coating liquid is coated on a cigarette paper base, and an embossing roller engraved with tobacco leaf texture is used to directly perform embossing after coating and drying to obtain cigarette paper with tobacco leaf vein texture. Although the method can moisturize one side of the cigarette paper, it cannot moisturize both sides of the cigarette paper. Summary of the invention

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0038] See also Figure 1-2 As shown, the present invention is a preparation device for two-way moisturizing cigarette paper, comprising a frame, the frame comprising a pair of beams A2 connected by two first connecting beams 21, and a pair of beams B23 connected by two second connecting beams 24; a connecting column 22 is connected between the beams A2 and the beams B23, and a supporting column 25 is connected to the bottom side of the beam B23; at the same time, in order to facilitate the conveyance of the cigarette paper to be processed for moisturizing, two first conveying rollers 101 with upper end surfaces in the same horizontal plane are rotatably connected between the inner side walls of the two beams A2, and the two beams are connected to the first conveying rollers 101 with upper end surfaces in the same horizontal plane. Two second conveying rollers 102 whose upper end surfaces are in the same horizontal plane are rotatably connected between the inner side walls of B23; therefore, when in use, the cigarette paper is conveyed by the first conveying roller 101 and the second conveying roller 102; at the same time, in order to facilitate the moisturizing of the two surfaces of the cigarette paper, a first moisturizing mechanism 1a for moisturizing one surface of the cigarette paper 100 is installed on the frame located between the two first conveying rollers 101; and a second moisturizing mechanism 1b for moisturizing the other surface of the cigarette paper 100 is installed on the frame located between the two second conveying rollers 102.

[0039] In order to achieve the tensioning of the cigarette paper 100 between the two first conveying rollers 101 and the cigarette paper 100 between the two second conveying rollers 102, as shown in FIG. Figure 13-14 A first guide roller 103 and a second guide roller 104 are arranged on the frame. When in use, the lower end surface of the first guide roller 103 is lower than the upper end surface of the first conveying roller 101, and the upper end surface of the second guide roller 104 is higher than the lower end surface of the second conveying roller 102; at the same time, when setting, a first conveying roller 101 is arranged between the first guide roller 103 and the first moisturizing mechanism 1a, and a second conveying roller 102 is arranged between the second guide roller 104 and the second moisturizing mechanism 1b.

[0040] like Fig.13 As shown, when in use, the cigarette paper 100 is controlled to pass through the first guide roller 103, the first conveying roller 101, the first moisture retaining mechanism 1a, the first conveying roller 101, the second conveying roller 102, the second moisture retaining mechanism 1b, the second conveying roller 102 and the second guide roller 104 from top to bottom.

[0041] like Fig.14 As shown, when in use, the cigarette paper 100 is controlled to pass through the second guide roller 104, the second conveying roller 102, the second moisture retaining mechanism 1b, the second conveying roller 102, the first conveying roller 101, the first moisture retaining mechanism 1a, the first conveying roller 101 and the first guide roller 103 from bottom to top.

[0042] On the basis of the above, if Figure 1-2 In order to facilitate the installation of the first guide roller 103 and the second guide roller 104, an upwardly protruding mounting seat A26 is provided on the upper surface of the beam A2, and a downwardly extending mounting seat B27 is provided on the bottom side surface of the beam B23; then, when in use, the two ends of the first guide roller 103 can be rotatably mounted on the inner walls of the two mounting seats A26, and at the same time, the two ends of the second guide roller 104 can be rotatably mounted on the inner walls of the two mounting seats B27.

[0043] Specifically, Figure 1-2 The two ends of the first moisturizing mechanism 1a are respectively installed on the inner walls of the two beams A2; the bottom side of the beam B23 is provided with a downwardly extending mounting block 28, and the two ends of the second moisturizing mechanism 1b are respectively installed on the inner walls of the two mounting blocks 28.

[0044] Furthermore, during installation, the first guide roller 103 is located directly above the second guide roller 104; during use, the cigarette paper 100 passes through the upper surfaces of the two first conveying rollers 101 and the lower surfaces of the two second conveying rollers 102; at the same time, the first moisturizing mechanism 1a and the second moisturizing mechanism 1b both rest against the lower surface of the cigarette paper in the conveying state during use.

[0045] It is known that if Figure 1-2As shown, the first moistening mechanism 1a and the second moistening mechanism 1b have the same structure. In order to facilitate the use of the first moistening mechanism 1a and the second moistening mechanism 1b, the moistening agent is applied to the two surfaces of the cigarette paper during use; Figure 3 , 5 -8. The first moisturizing mechanism 1a provided in the present invention comprises a shell 1, the top of which is provided with an opening 11, a brush roller 12 rotatably arranged in the shell 1 against the surface of the cigarette paper 100, and the upper end surface of the brush roller 12 protrudes from the top end surface of the shell 1; at the same time, an oil supply pipe 15 with both ends closed is arranged in the shell 1 on one side of the brush roller 12, one side of the oil supply pipe 15 is in contact with the upper half of the brush roller 12, and a rectangular oil filling hole 159 is arranged along the length direction of the side of the oil supply pipe 15 in contact with the brush roller 12; and then, when in use, a lubricant is injected into the oil supply pipe 15, and at this time, the lubricant in the oil supply pipe 15 is discharged through the rectangular oil filling hole 159 and infiltrates into the outer peripheral side of the brush roller 12, and then the brush roller 12 is used to roll-coat the lubricant adsorbed on its surface onto a surface of the cigarette paper 100 passing through its surface.

[0046] It is known that during use, it is often necessary to roll-coat the two surfaces of the cigarette paper 100 of different widths for moisturizing, that is, it is necessary to control the actual width of the rectangular oiling hole 159 to be adapted to the width of the cigarette paper 100; Fig.12 In the present invention, a convex ring A152 and a convex ring B154 are respectively arranged at both ends of the oil supply pipe 15, and the opposite sides of the convex ring A152 and the convex ring B154 are respectively connected with a piston A153 and a piston B155 which are sealed and slide along the inner wall of the oil supply pipe 15 through a spring A1521 and a spring B1541; a movable block 151 which slides along the inner wall of the oil supply pipe 15 is arranged between the convex ring A152 and the convex ring B154; one side of the movable block 151 is connected to the piston B155 through a traction rope A1551, and the other side of the movable block 151 is connected to an L-shaped rod 1571, and the L-shaped rod 1571 is connected to the piston A153 through a traction rope B1531; the convex ring A152 is arranged at the A guide rod 157 is arranged on the inner wall of the oil supply pipe 15 between the movable block 151, and one end of the L-shaped rod 1571 connected to the traction rope B1531 moves in the area between the guide rod 157 and the piston A153. The outer side walls of the piston A153 and the piston B155 are provided with sealing sliders along their axial directions for guiding and sliding along the length direction of the rectangular oil filling hole 159. When in use, the movable block 151 is controlled to move along the inside of the oil supply pipe 15, so as to control the piston A153 and the piston B155 to move in relative or opposite directions. When the two sealing sliders are used in combination, the actual use width of the rectangular oil filling hole 159 is adjusted accordingly in actual use.

[0047] Based on the above, in order to facilitate the control of the movable block 151, piston A153 and piston B155 to move in the axial direction along the inner wall of the oil supply pipe 15 without rotating during use, a guide strip 158 is provided along the length direction of the inner wall of the oil supply pipe 15 between the convex ring A152 and the convex ring B154, and the outer wall of the movable block 151 is provided with a guide groove 1511 cooperating with the guide strip 158, and a channel A1510 cooperating with the rectangular oil filling hole 159; the outer walls of the convex ring A152 and the convex ring B154 are provided with a channel B1540 and a channel C cooperating with the guide strip 158.

[0048] It is known that if Figure 7 In order to facilitate the need to control the movable block 151 to slide along the inner wall of the oil supply pipe 15 during use, the present invention provides a magnetic core in the movable block 151, and a major arc magnetic ring 163 is clamped on the outer wall of the oil supply pipe 15. Then, when the major arc magnetic ring 163 is controlled to move along the length direction of the outer side of the oil supply pipe 15 during use, the movable block 151 is driven to move along the length direction of the inner side of the oil supply pipe 15.

[0049] That is, when using Figure 7 In order to control the movable block 151 to move along the length direction in the oil supply pipe 15, the superior arc type magnetic ring 163 can be driven to move along the length direction on the outside of the oil supply pipe 15. Therefore, the present invention can connect one side of the magnetic slider 161 of a rodless cylinder through the connecting part 162 on one side of the superior arc type magnetic ring 163, and the magnetic slider 161 is mounted on the cylinder barrel 16 of the rodless cylinder. When in use, the magnetic slider 161 of the rodless cylinder is controlled to move on the cylinder barrel 16, thereby driving the superior arc type magnetic ring 163 to move along the length direction on the outside of the oil supply pipe 15.

[0050] At the same time, in the above, Figure 7 In order to facilitate the limiting of the superior arc magnetic ring 163 during use and prevent the superior arc magnetic ring 163 from rotating along the outer wall of the oil supply pipe 15, a limiting strip A17 and a limiting strip B18 are provided on the outer wall of the oil supply pipe 15 along its length direction; the limiting strip A17 and the limiting strip B18 are respectively located on the upper and lower sides of the rectangular oil filling hole 159, and a guide slope 181 is provided on the side of the limiting strip B18 close to the brush roller 12. At the same time, the setting of the guide slope 181 facilitates the blocking of the lubricant discharged from the rectangular oil filling hole 159 during use, so as to prevent the lubricant from flowing to the outer wall of the oil supply pipe 15 and flowing to the junction of the superior arc magnetic ring 163 and the oil supply pipe 15.

[0051] It can be known that, when in use, the first moisturizing mechanism 1a and the second moisturizing mechanism 1b provided by the present invention are both against the lower surface of the cigarette paper 100 in the conveying state, and utilize the lubricant roller adhered to the surface of the brush roller 12 to be applied to the lower surface of the cigarette paper 100, so as to avoid the lubricant adhered to the surface of the brush roller 12 from dripping easily under the action of gravity when the brush roller 12 is located above the cigarette paper and contacts the upper surface of the cigarette paper, thereby making it impossible to perform a uniform moisturizing operation on the surface of the cigarette paper 100.

[0052] Therefore, in order to achieve uniform coating of the humectant on the surface of the cigarette paper 100 by the brush roller 12, Figure 6 When in use, it is necessary to control in advance that the surface of the brush roller 12 is uniformly absorbed with the lubricant. Since the rectangular oil filling hole 159 is used to discharge excess lubricant to the brush roller 12, the brush roller 12 is easy to absorb excessive lubricant, or the amount of lubricant absorbed by the brush roller 12 in any area along its length direction is different; the present invention is rotatably connected to an oil scraper roller 1241 through a rotating shaft B1240 in the shell 1 located directly below the brush roller 12. When in use, the oil scraper roller 1241 contacts the brush roller 12, and then the oil scraper roller 1241 is used to control the lubricant adsorbed on the surface of the brush roller 12 to be uniformly distributed to the surface of the brush roller 12, and then the brush roller 12 is used to evenly roll the lubricant onto the surface of the cigarette paper 100.

[0053] like Figure 3-4 , and 9-11, the brush roller 12 is rotatably mounted in the shell 1 through the rotating shaft A120, and a gear A121 is set at one end of the rotating shaft A120 that passes through the shell 1, and a gear C124 is set at one end of the rotating shaft B1240 that passes through the shell 1; the gear B122 is rotatably mounted on the outer end surface of the shell 1 between the gear C124 and the gear A121 through a rotating column 1220, and the gear B122 is respectively meshed with the gear C124 and the gear A121; a U-shaped motor mounting frame 1250 is also installed on the outer end surface of the shell 1, and a rotating motor 1251 is installed on the U-shaped motor mounting frame 1250, and a gear D1252 is connected to the output shaft of the rotating motor 1251, and the gear D1252 is meshed with the gear C124. Based on the above arrangement, when in use, the effect of the rotating motor 1251 is utilized, and based on the arrangement of multiple gears, it is convenient to control the relative rotation of the brush roller 12 and the oil scraper roller 1241 when in use.

[0054] Mounting blocks 19 are respectively provided on both end surfaces of the housing 1, and the mounting blocks 19 are welded and fixed on the frame; bearings A1200 and bearings B1242 for mounting rotating shafts A120 and B1240 are respectively provided at the ends of the housing 1.

[0055] When using, Figure 6 and 10Since the rectangular oil injection hole 159 discharges a large amount of lubricant and the oil scraper roller 1241 causes the lubricant to drip, in order to recover the excess dripping lubricant, a filtering structure 13 is arranged directly below the oil scraper roller 1241, and an oil storage chamber is arranged below the filtering structure 13, in which an oil injection pump 14 is installed; the bottom and top of the shell 1 are respectively penetrated by an oil injection pipe A141 and an oil injection pipe B142 connected by a hose, one end of the oil injection pipe B142 is connected to the middle position of the oil supply pipe 15, and one end of the oil injection pipe A141 is connected to the oil injection pump 14; at the same time, the filtering structure 13 includes a microporous filter membrane 133, a porous filter plate 132 and a gauze 131 from bottom to top; when in use, the gauze 131 is used to filter large particles of impurities, and then the microporous filter membrane 133 is used to filter again, so as to obtain pure lubricant.
