Description

Technical Field

[0001] The utility model relates to the technical field of cigarette manufacturing, in particular to a strip cigarette ironing device. Background Art

[0002] A long strip of cigarettes is wrapped with a layer of transparent plastic on the outer surface to achieve the purpose of moisture-proof. However, when wrapping the transparent plastic, it may be unevenly wrapped, resulting in bubbles and bulges, which affect the appearance. In order to improve the packaging quality of the transparent paper for the outer packaging of large cigarette packs, in view of the phenomenon of loose wrinkles and uneven appearance of the transparent paper for the large cigarette packs, many domestic manufacturers have added a beauty shaping device for the transparent paper of the large cigarette packs to eliminate the loose wrinkles of the transparent paper for the large cigarette packs by ironing.

[0003] The patent document with the publication number of CN208102528U discloses such a strip cigarette ironing device, which includes a conveying platform and an ironing mechanism. The ironing mechanism includes a rectangular rising channel, a cigarette pack conveying mechanism and a cigarette outlet track. There are pawls and two shaping soldering irons in the rectangular rising channel. The two shaping soldering irons at the relative positions are respectively connected to the soldering iron cylinders. There is a flat-pushing cigarette cylinder above the rectangular rising channel. The cigarette pack conveying mechanism includes a cylinder mechanism and a cigarette-pushing plate. The cigarette outlet track is fixed on the conveying platform through a support frame. The cigarette outlet track is connected to the support frame through a rotating shaft. One end of the cigarette outlet track is hinged to one end of a smoke baffle, and the other end of the smoke baffle is connected to a track-changing cylinder. There is a groove on the conveying platform, and a cigarette-pushing plate is arranged in the groove. The lower end of the cigarette-pushing plate is connected to the cylinder mechanism.

[0004] The ironing method of the prior art is as follows: First, a first-level cylinder applies force to the bottom surface of the strip cigarette and pushes the strip cigarette upward into the rising channel containing the shaping soldering iron; then the shaping soldering iron irons the side surfaces of both ends of the strip cigarette along the conveying direction; then the flat-pushing cigarette cylinder applies force to the side surface of the strip cigarette and pushes the strip cigarette out. The side surface of the strip cigarette that is stressed during the flat-pushing is exactly the side surface that has been ironed. However, after the side surface of the strip cigarette is ironed, it takes a certain amount of time to completely cool down. The uncompletely cooled plastic will have a certain viscosity, which causes the plastic on the side surface of the hot, softened and viscous strip cigarette to come into contact with the push plate during the flat-pushing process, and the plastic is easily adhered to the push plate, which not only affects the pushing-out effect of the strip cigarette, but also causes damage to the ironed plastic packaging.

Detailed Embodiments

[0023] The following are the detailed embodiments of the present utility model. In combination with the drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0024] A cigarette carton ironing device includes an ironing component and an evacuation component. The ironing component is used to iron the plastic packaging on the side of the cigarette carton to eliminate wrinkles and uneven appearance. The evacuation component is used to assist the cigarette carton conveying device to push the cigarette carton out from the ironing component after the cigarette carton is ironed, or to push the cigarette carton out from the ironing component in time when the conveying device stops, so as to avoid damage to the cigarette carton caused by long-term ironing.

[0025] As Figure 1 shown, the ironing component includes an upper iron 11 and a lower iron 12 arranged in sequence along the vertical direction, and an ironing control member for driving the upper iron 11 or / and the lower iron 12 to move in the vertical direction. By conveying the cigarette carton between the upper iron 11 and the lower iron 12, and then driving the upper iron 11 or / and the lower iron 12 to move in the vertical direction until the upper long side and the lower long side of the cigarette carton are respectively in contact with the upper iron 11 and the lower iron 12, and then turning on the heating devices of the upper iron 11 and the lower iron 12 to make them heat up to iron the plastic packaging on the side of the cigarette carton.

[0026] In this embodiment, the specific implementation method is: in accordance with Figure 1 the shown direction, the conveying direction of the cigarette carton is from the left rear to the right front. First, the conveying device is basically the same as the prior art, including a conveying bottom plate. Conveyor belts are respectively arranged at both ends of the conveying bottom plate perpendicular to the conveying direction. The conveying surface of the conveyor belt is a vertical surface, and the conveying direction of the conveyor belt is parallel to the conveying direction of the cigarette carton. By placing the cigarette carton on the conveying bottom plate and making the two short side surfaces of the cigarette carton respectively in contact with the conveying surfaces of the two conveyor belts, and adjusting the surface friction of the conveying bottom plate to be smaller (for example, coating a low surface energy coating, such as a polytetrafluoroethylene coating) and the surface friction of the conveyor belt to be larger, the cigarette carton can be driven by the conveyor belt to be conveyed on the conveying bottom plate. Here, it should be noted that the height of the conveying surface in the vertical direction should be less than the height of the cigarette carton in the vertical direction, so that the lower part of the short side surface of the cigarette carton is in contact with the conveying surface, and the upper part is exposed for the subsequent evacuation component to apply force.

[0027] An opening is provided on the conveying bottom plate, and the lower iron 12 is provided at the opening. By controlling the upper surface of the lower iron 12 to be flush with the upper surface of the conveying bottom plate, the cigarette carton can be conveyed and abutted against the lower iron 12. The upper iron 11 is correspondingly arranged above the lower iron 12. At this time, the ironing control member only needs to control the upper iron 11 to move in the vertical direction. In this embodiment, as Figure 1 shown, the ironing control member includes a fixed frame 131 and a lifting cylinder 132 arranged on the fixed frame 131. Specifically, columns are respectively arranged at both ends of the conveying bottom plate perpendicular to the conveying direction, and the fixed frame 131 is arranged between the two columns. By installing the body of the lifting cylinder 132 on the fixed frame 131 and connecting the upper iron 11 with the piston rod of the lifting cylinder 132, the upper iron 11 can be driven to move up and down.

[0028] The upper iron 11 can be directly connected or indirectly connected to the piston rod of the lifting cylinder 132. In some embodiments, as Figure 1 shown, the upper iron 11 is connected to the piston rod of the lifting cylinder 132 through an adjusting member. The adjusting member includes a threaded column 133 provided on the upper iron 11, a fixing plate 134 connected to the piston rod of the lifting cylinder 132 and provided with a through hole for the threaded column 133 to pass through, and a nut threadedly connected to the threaded column 133 and abutting against the upper surface of the fixing plate 134. During ironing, the fixing plate 134 and the upper iron 11 move together in the vertical direction. By controlling the position of the nut on the threaded column 133, the distance between the fixing plate 134 and the upper iron 11 can be adjusted. Generally speaking, in order to avoid damaging the cigarette cartons, the stroke of the piston rod of the lifting cylinder 132 is fixed; the adjusting member can adjust the shortest distance between the upper iron 11 and the lower iron 12 without changing the stroke of the piston rod, so as to adjust the pressing force of the iron on the cigarette cartons and the ironing effect.

[0029] In some embodiments, after ironing, in order to cool and shape in time and avoid the heated and softened plastic packaging from being affected by the outside world and changing, as Figure 1 shown, the ironing assembly further includes a cooling plate 14. The cooling plate 14 is arranged downstream of the iron structure in the cigarette conveying direction. When the cigarette cartons pass through the ironing by the iron, they can be conveyed under the cooling plate 14 to obtain cooling and shaping. The way for the cooling plate 14 to achieve cooling is not limited. In this embodiment, the cooling plate 14 is hollow inside and communicated with a structure capable of discharging air, such as a blower. At the same time, a plurality of air outlets are provided on the side close to the lower iron 12 to cool the cigarette cartons by air cooling. The installation method of the cooling plate 14 is not limited. In this embodiment, as Figure 1 shown, the cooling plate 14 is connected to the upper iron 11 through a connecting member. The horizontal plane where the lower bottom surface of the cooling plate 14 is located is slightly higher than the horizontal plane where the lower bottom surface of the upper iron 11 is located. In this setting method, the cooling plate 14 can adjust the height together with the upper iron 11, and there is no need to repeatedly adjust the height of the cooling plate 14 after adjusting the height of the upper iron 11, which is more convenient to apply to cigarette cartons of various heights.

[0030] In some cases, if the conveying device fails and cannot convey the cigarette cartons out from between the upper and lower irons in time, the cigarette cartons at this place will be damaged due to being ironed at high temperature for a long time, and great changes will occur in the appearance and internal quality of the products, seriously affecting the quality of the products. Therefore, an emptying assembly is also provided in the ironing device.

[0031] As Figure 2As shown in the figure, the direction from the left front to the right rear is the first direction, which belongs to the horizontal direction and is perpendicular to the conveying direction of the cigarette cartons. The emptying assembly includes a first clamping plate 21 and a second clamping plate 22 arranged in sequence along the first direction, a clamping control member for driving the first clamping plate 21 or / and the second clamping plate 22 to move along the first direction, and an emptying control member for driving the clamping control member to move along the conveying direction of the cigarette cartons. In this embodiment, the clamping control member includes a first bracket 231, a second bracket 232, and a connecting frame 233 connecting the first bracket 231 and the second bracket 232; a first cylinder is provided on the first bracket 231, and the piston rod of the first cylinder is connected to the first clamping plate 21; a second cylinder is provided on the second bracket 232, and the piston rod of the second cylinder is connected to the second clamping plate 22. Based on this, the first cylinder and the second cylinder can drive the first clamping plate 21 and the second clamping plate 22 to move respectively to tightly press against the two short-side sides of the cigarette cartons. The emptying control member includes an exhaust cylinder 241, and the piston rod of the exhaust cylinder 241 is connected to the connecting frame 233. Based on this, the exhaust cylinder 241 can drive the clamping control member and the cigarette cartons clamped thereon to move. Among them, the body of the exhaust cylinder 241 can be installed anywhere; the installation of the clamping control member should ensure its stability during clamping and subsequent pushing. Therefore, in this embodiment, the exhaust cylinder 241 is installed on the fixing bracket 131 by using the above-mentioned fixing bracket 131. At the same time, the fixing bracket 131 is set to be T-shaped or cross-shaped, and the part perpendicular to the conveying direction of the cigarette cartons is used to connect with the above-mentioned support columns, and a guiding groove is provided on the part parallel to the conveying direction of the cigarette cartons. Then a slider is provided on the connecting frame 233, and the slider is slidably connected to the guiding groove. To further ensure the stability of the clamping control member, parallel sliding grooves in the conveying direction can be respectively provided at both ends of the conveying bottom plate, and the first bracket 231 and the second bracket 232 are respectively slidably arranged in the sliding grooves.

[0032] Based on the above structure, when the conveying device stops, the emptying assembly can be started. The first cylinder and the second cylinder respectively drive the first clamping plate 21 and the second clamping plate 22 to move to tightly press against the two short-side sides of the cigarette cartons respectively, so as to clamp the cigarette cartons, and the clamping control member and the cigarette cartons form an integral structure. Then the exhaust cylinder 241 drives this integral structure to be pushed out from between the soldering irons along the guiding groove to realize the emptying of the cigarette cartons.

[0033] In some embodiments, since the evacuation component does not change the distance of the cigarette cartons in the vertical direction, there will be friction between the lower bottom surface of the cigarette cartons and the lower soldering iron 12 or the conveying bottom plate when pushing after clamping the cigarette cartons. Although generally the cigarette cartons are conveyed on the conveying bottom plate and the friction on the conveying bottom plate is very small, since the lower bottom surface of the cigarette cartons at this time has not cooled and solidified after ironing, directly rubbing on the conveying bottom plate may still have problems of adhesion and breakage. Therefore, an adjustment control member for driving the cigarette cartons to move in the vertical direction is further included to make the cigarette cartons suspended and avoid the friction problem during pushing. The setting method of the adjustment control member is not limited. Preferably, the cigarette cartons are indirectly driven to move by controlling the clamping plate or the bracket to move in the vertical direction. For example, in this embodiment, the adjustment control member includes a first telescopic member disposed between the first bracket 231 and the connecting frame 233, and a second telescopic member disposed between the second bracket 232 and the connecting frame 233. By controlling the contraction of the first telescopic member and the second telescopic member, the first bracket 231 and the second bracket 232 can be driven to rise, and then the clamped cigarette cartons can be driven to rise. Among them, in order to more simply control the expansion and contraction of the first telescopic member and the second telescopic member, the first telescopic member and the second telescopic member can be selected as cylinders. The cylinder body is disposed on the connecting frame 233, and the piston rod is connected to the first bracket 231 and the second bracket 232.

[0034] At this time, during evacuation, the first cylinder and the second cylinder respectively drive the first clamping plate 21 and the second clamping plate 22 to move to respectively abut against the two short-side sides of the cigarette cartons, so as to clamp the cigarette cartons. The clamping control member and the cigarette cartons form an integral structure. Then the first telescopic member and the second telescopic member contract, driving the brackets, the clamping plates and the cigarette cartons in the integral structure to rise a certain distance slightly, so that the lower bottom surface of the cigarette cartons does not abut against the lower soldering iron 12 or the conveying bottom plate. Then the exhaust cylinder 241 works, pushing the connecting frame 233 to be pushed out along the guide groove, driving the clamping control member and the cigarette cartons to be pushed out.

[0035] On this basis, in some embodiments, the first cylinder can be rotatably connected to the first bracket 231, and the second cylinder can be rotatably connected to the second bracket 232. The rotation connection method is not limited. For example, openings can be provided on the first bracket 231 and the second bracket 232, and shafts can be provided on the cylinder bodies of the first cylinder and the second cylinder. The shafts can be connected to the openings through rotary bearings. Further, a handle is provided on the shaft to control the rotation of the first cylinder and the second cylinder. At this time, the first clamping plate 21 and the second clamping plate 22 clamp the cigarette cartons, and after the cigarette cartons rise a certain distance slightly, the first cylinder and the second cylinder can be synchronously rotated to drive the cigarette cartons to rotate. When the cigarette cartons rotate 90°, the first telescopic member and the second telescopic member extend to drive the cigarette cartons to descend and abut against the lower soldering iron 12, and then the clamping of the cigarette cartons is released. At this time, the other pair of long-side sides of the cigarette cartons can be ironed to improve the ironing efficiency.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
