Description

Film packaging paper film laminating method

Technical Field

The application relates to the technical field of film packaging, in particular to a paper film laminating method for film packaging.

Background

When the paper film coating package is applied to product packages with certain heights, the film needs to be longer than paper in the paper film coating production stage. In the laminating stage of the paper board, the two ends of the film are adhered to the adhesive areas of the paper board, but the length of the film is longer than that of the paper board, so that articles can be placed between the film and the paper board, and the packaging of products is realized.

At present, the local lamination of paper films in the industry mostly adopts a film sucking roller to realize the lamination of films and paperboards in a ratio of 1:1, namely equal-length lamination. For the realization of unequal length films such as film to board ratios greater than 1:1, the following are employed in the equipment and production process industries: the roller assembly with the specific modeling realizes the pretreatment of the film, in particular to the meshed transmission of the roller with the convex part and the roller with the concave part, and the non-equal-length film coating between the film and the paper is realized through convex-concave matching by utilizing the convex-concave principle. However, the uneven matching of the two film sucking rollers is used for realizing the film covering with different lengths, and the length extension of the film is limited because the protruding height of the protrusions and the depth dimension of the grooves are fixed.

Unless defined otherwise, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. The term "and/or" as used in the specification of this application includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the present application provides a film wrapping paper film laminating apparatus 100, where the film laminating apparatus 100 is used to laminate paper boards 101 and films 102 with different dimensional ratios, and the laminated structure (as shown in fig. 8) can be used for packaging products, especially products with a certain height.

As shown in fig. 2, the paper film laminating apparatus 100 provided in the present application at least includes a base 10, a film feeding mechanism 20, a first adsorption mechanism 30, a second adsorption mechanism 40, and a film winding mechanism 50; the base 10 is used as a basic carrier for carrying various mechanisms and components. The film feeding mechanism 20 is used for feeding the film 102 for lamination. Wherein the film 102 has a free end 103, the free end of the film 102 moves toward the first adsorption mechanism 30 during the continuous conveyance of the film feeding mechanism 20. The first adsorption mechanism 30 is mounted on the base 10 for adsorbing the free end 103 of the film 102. The second adsorption mechanism 40 is spaced from the first adsorption mechanism 30, and is used for adsorbing one end of the film 102, which is close to the film feeding mechanism 20; the film winding mechanism 50 is rotatably installed on the base 10, and is used for acquiring and winding the film 102 between the first adsorption mechanism 30 and the second adsorption mechanism 40; at least part of the first adsorption mechanism 30 and the second adsorption mechanism 40 can move relative to the base 10 to respectively drive the free end 103 of the film 102 and the end close to the film feeding mechanism 20 to move towards the paper board 101 and cover the paper board 101, and simultaneously enable the film winding mechanism 50 to release the wound film 102.

It will be appreciated that in this application, the length of film 102 is increased as film feed mechanism 20 continues to feed (unwind) the film. When the length of the film 102 reaches a certain length, the film winding mechanism 50 acquires the film 102 positioned between the first adsorption mechanism 30 and the second adsorption mechanism 40 and winds up, and at this time, part of the film 102 is wound up on the film winding mechanism 50; further, the first adsorption mechanism 30 adsorbs the free end 103 of the film 102, and the second adsorption mechanism 40 adsorbs one end of the film 102 close to the film feeding mechanism 20; the free end 103 of the film 102 and the end close to the film feeding mechanism 20 are respectively moved towards the paper board 101 under the driving of the first adsorption mechanism 30 and the second adsorption mechanism 40, and are adhered to the glue coating area on the paper board 101. The film 102 rolled by the film rolling mechanism 50 is released under the driving of the first and second adsorption mechanisms 30 and 40, and the released film 102 can be hung or stacked on the paper board 101; thus, the film 102 is rolled up and released by the film rolling mechanism 50, and the covering requirements of different proportions between the length of the film 102 and the length of the paper board 101 can be realized.

It should be noted that, during the film winding process of the film winding mechanism 50, the film feeding mechanism 20 also continuously feeds the film, and when the length of the film 102 reaches the preset length, the first adsorption mechanism 30 also adsorbs the free end 103 of the film 102. Of course, the first adsorption mechanism 30 may adsorb the free end 103 when the film feeding mechanism 20 starts to feed the film, and the first adsorption mechanism 30 adsorbs the free end 103; alternatively, the first adsorption mechanism 30 may adsorb the free end 103 after the film is wound up by the film winding mechanism 50, that is, after the film is wound up by the film winding mechanism 50, the free end 103 may be adsorbed.

As shown in fig. 1, the film feeding mechanism 20 is suspended from the base 10. The film feeding mechanism 20 may be supported by the base 10 or by another member having a supporting function. The film feeding mechanism 20 is relatively located above the base 10 along a direction perpendicular to the base 10. This allows the film feeding mechanism 20 to have a sufficient stroke when releasing the film.

In one embodiment, the film feeding mechanism 20 includes a film feeding roller 21 and a film feeding motor (not shown), and the film feeding roller 21 is wound with a film 102 to form a roll of film. The film feeding motor is connected with the film feeding roller 21 and drives the film feeding roller 21 to rotate, so that the film feeding or film conveying 102 is realized. Of course, the type of the film feeding mechanism 20 is not limited to the above-described structure, and other structures having a film feeding function may be employed.

As shown in fig. 2, the primary function of the first adsorption mechanism 30 is to adsorb the free end 103 of the film 102 and drive the free end of the film 102 to move and achieve the lamination between the film 102 and the cardboard 101. In a direction perpendicular to the base 10, the first suction mechanism 30 is located between the base 10 and the film feeding mechanism 20. In this way, the structure of the paper film laminating apparatus 100 is also made more compact.

The first adsorption mechanism 30 includes a first base 31, a first adsorption plate 32, and a second driving member 33. The first base 31 is mounted on the base 10 and is used as a bearing. The first adsorption plate 32 is slidably mounted on the first base 31 to adsorb the free end 103 of the film 102; the second driving member 33 is provided with a motor or a cylinder or the like. The second driving member 33 is connected to the first adsorption plate 32, and is used for driving the first adsorption plate 32 to slide on the first base 31 so as to move towards the paper board 101. It will be appreciated that the sliding arrangement herein may be configured to slide, and the guiding properties of the sliding structure itself may be utilized, to make the movement of the first suction plate 32 more reliable; and the sliding mode is simple and the cost is low. Here, the sliding structure may be provided as a slide rail and a slider structure. Of course, the movement of the first adsorption plate 32 relative to the first base 31 is not limited to the above-mentioned sliding, and may be provided in a screw structure or directly by using an air cylinder, etc., which is not limited herein.

The first housing 31 may be provided integrally with the base 10 or separately. The base 10 is integrated, so that the whole base is more stable and reliable. And is provided as a split type, and the processing of the base 10 and the first seat 31 can be facilitated. In the present embodiment, the first housing 31 may be provided separately from the base 10.

As shown in fig. 2, the surface of the first housing 31 facing the base 10 is provided with a recess 311, and a chamber is defined between the recess 311 and the base 10 after the first housing 31 is mounted on the base 10. The first adsorption plate 32 is accommodated in a chamber provided to penetrate in a direction in which the first adsorption plate 32 moves, so that the first adsorption plate 32 is protruded out of the chamber by the second driving member 33 and moves toward the paper sheet 101.

The first adsorption plate 32 is provided with a box shape, a plurality of first adsorption holes 321 are formed in one side of the first adsorption plate 32 facing the paper board 101, and an adsorption member is arranged in the first adsorption plate 32. The absorbing member is an air pump or a vacuum pump, and after the absorbing member is started, air is continuously absorbed into the first absorbing plate 32 through the first absorbing holes 321, so that negative pressure is formed inside the first absorbing plate 32 relative to the outside of the first absorbing plate 32, and the film 102 is absorbed on the first absorbing plate 32.

As shown in fig. 2, the main function of the second adsorption mechanism 40 is to adsorb one end of the film 102 close to the film feeding mechanism 20 and drive the film 102 to move so as to realize the covering between the film 102 and the paper board 101. The second adsorption mechanism 40 is located above the first adsorption mechanism 30 in a direction perpendicular to the base 10; meanwhile, the second adsorption mechanism 40 is located between the first adsorption mechanism 30 and the film feeding mechanism 20. In this way, the above structures are sequentially arranged in a direction perpendicular to the base 10, so that the structure of the paper film laminating apparatus 100 is more compact. And, the distance between the second adsorption mechanism 40 and the first adsorption mechanism 30 corresponds to the distance between the glue spreading areas of the paper sheet 101. Thus, when the second adsorption mechanism 40 drives the film 102 to move towards the paper board 101, the paper board 101 and the film 102 can be correspondingly covered.

The second adsorption mechanism 40 includes a second housing 41, a second adsorption plate 42, and a third driving member 43. The second seat 41 is used as a carrier and is suspended relative to the first adsorption mechanism 30, i.e. the second seat 41 and the first adsorption mechanism 30 are spaced apart. The second adsorption plate 42 is slidably mounted on the second base 41 for adsorbing one end of the film 102 near the film feeding mechanism 20; the third driving member 43 is provided as a motor or a cylinder or the like. The third driving member 43 is connected to the second adsorption plate 42, and is used for driving the second adsorption plate 42 to slide on the second base 41 and move towards the paper board 101, so as to drive one end of the film 102, which is close to the film feeding mechanism 20, to cover the paper board. It will be appreciated that the sliding arrangement herein may be configured to take advantage of the inherent guiding properties of the sliding arrangement to make the movement of the second suction plate 42 more reliable; and the sliding mode is simple and the cost is low. Here, the sliding structure may be provided as a slide rail and a slider structure. Of course, the movement of the second adsorption plate 42 relative to the second seat 41 is not limited to the above-described sliding, and may be provided in a screw structure or directly by an air cylinder, etc., which is not limited herein.

The second housing 41 is spaced apart from the first housing 31 in a direction perpendicular to the base 10. The second housing 41 is provided with a recess (not shown) on the side facing away from the base 10, after the second housing 41 is mounted on the base 10 or other carrier. The second suction plate 42 is mounted in the recess and the recess is provided through in the direction of movement of the second suction plate 42 so that the second suction plate 42 protrudes and moves in the direction of the cardboard 101 under the influence of the third driving member 43.

As shown in fig. 2, the second adsorption plate 42 is provided in a box shape, a plurality of second adsorption holes 421 are formed in a side of the second adsorption plate 42 facing the paper sheet 101, and an adsorption member is provided in the second adsorption plate 42. The absorbing member is an air pump or a vacuum pump, and after the absorbing member is started, air is continuously absorbed into the second absorbing plate 42 through the second absorbing holes 421, so that negative pressure is formed in the second absorbing plate 42 relative to the outside of the second absorbing plate 42, and the film 102 is absorbed on the second absorbing plate 42.

As shown in fig. 2, the film winding mechanism 50 is provided rotatably mounted to the base 10, and is located between the base 10 and the film feeding mechanism 20. The film winding mechanism 50 is mainly used for winding the film 102, so that the length of the film 102 is longer than that of the paperboard, and the production requirements of different proportions of the paperboard 101 and the film 102 are realized. It will be appreciated that by precisely controlling the length of film wound by the film winding mechanism 50, it is possible to achieve a combination of different film 102 lengths and paperboard 101. Further, by providing the film winding mechanism 50, when the film feeding mechanism 20 can continuously feed the film 102, it can achieve endless winding of the film, that is, here, endless extension of the film 102.

The film winding mechanism 50 may acquire the film automatically or manually. Here, the automatic acquisition, i.e., film winding mechanism 50 may automatically suck up the film; and manual access is provided to manually position the film on the film winding mechanism 50. In this embodiment, the film winding mechanism 50 is configured to automatically suck the film, so that the film is positioned on the film winding mechanism 50, thereby realizing automation of film winding and providing production efficiency.

In one embodiment, the film rolling mechanism 50 is disposed between the base 10 and the second suction mechanism 40. Specifically, the film rolling mechanism 50 is disposed between the first suction mechanism 30 and the second suction mechanism 40 in a direction perpendicular to the base 10, so that the base 10, the first suction mechanism 30, the film rolling mechanism 50, and the second suction mechanism 40 are disposed in this order in the direction perpendicular to the base 10. Therefore, the structure of the paper film laminating equipment is more compact.

As shown in fig. 2, the film winding mechanism 50 is mounted on the first adsorption mechanism 30. Specifically, the film winding mechanism 50 is mounted on the first base 31 and is located on a side of the first base 31 near the film 102, so that the film winding mechanism 50 winds the film 102.

The film winding mechanism 50 includes a first driving member 51, a first rotating member 52, and an acquisition member (not shown). The first drive member 51 may be provided as a motor or other power means. The first rotating member 52 is rotatably mounted on the base 10, and is capable of winding up or releasing the film 102 under the driving of the first driving member 51. The acquisition member is provided on the first rotating member 52 for acquiring the film between the first suction mechanism 30 and the second suction mechanism 40 (or the film between the base 10 and the second suction mechanism 40) so that the first rotating member 52 can roll up the film 102 during rotation.

In one embodiment, as shown in fig. 4, the first rotating member 52 is configured as a roller, and the roller is provided with a through hole (not shown) that communicates with the interior of the roller; the acquisition member is provided as an adsorption member capable of generating an adsorption force through the through-hole to adsorb the film 102 to the outer surface of the roll. So configured, the acquisition member and the first rotatable member 52 can be formed as a single unit to further facilitate the rolling of the film 102 by the first rotatable member 52. Here, the suction member is an air pump or a vacuum pump, and after the suction member is started, air is continuously sucked into the roller through the through hole, so that negative pressure is formed in the roller relative to the outside of the roller, and the film 102 is sucked into the roller. Of course, the roller and the suction member may be provided with the same member, such as a vacuum suction roller or the like.

Further, as shown in fig. 2, the film rolling mechanism 50 further includes a third housing 53, the third housing 53 is mounted on the first housing 31, the first rotating member 52 is rotatably mounted on the third housing 53, and the first driving member 51 is also mounted on the third housing 53 and connected to the first rotating member 52.

As shown in fig. 1 or fig. 5, the paper film laminating apparatus 100 further includes an adjusting mechanism 60, and the adjusting mechanism 60 is used for adjusting the distance between the first adsorbing mechanism 30 and the second adsorbing mechanism 40. It will be appreciated that the distance between the first suction mechanism 30 and the second suction mechanism 40 corresponds to the size (width or length) of the sheet 101, and that different distances between the first suction mechanism 30 and the second suction mechanism 40 can accommodate different sizes of sheet 101. Therefore, the adjusting mechanism 60 is arranged to adjust the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40, so that the paper film laminating device provided by the application can realize lamination between paper boards 101 with different sizes and films 102 with different sizes. In other words, the production requirements of the overlap between the cardboard 101 and the film 102 in any ratio can be achieved.

Further, the adjustment mechanism 60 may be provided as an automatic adjustment mechanism or a manual adjustment mechanism. The automatic adjusting mechanism can automatically adjust the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40. The manual adjustment mechanism requires a manual effort to adjust the distance between the first adsorption mechanism 30 and the second adsorption mechanism 40. It will be appreciated that the particular choice of adjustment mechanism 60 may be set according to actual manufacturing or operational requirements and is not limited herein. In this embodiment, the adjustment mechanism 60 is provided as an automatic adjustment mechanism to provide a basis for an automatic laminating line between the sheet 101 and the film 102.

In one embodiment, as shown in fig. 2 or 5, the adjusting mechanism 60 includes at least a fourth driving member (not shown) and a telescopic unit 61; the telescopic unit 61 is arranged between the first adsorption mechanism 30 and the second adsorption mechanism 40, and is respectively connected with the first adsorption mechanism 30 and the second adsorption mechanism 40; the fourth driving member is used for driving the second adsorption mechanism 40 to move (the telescopic unit 61 is passively telescopic) or the telescopic unit 61 is actively telescopic, so that the second adsorption mechanism 40 is far away from the first adsorption mechanism 30, and the distance between the two is adjusted.

Further, the telescopic unit 61 may be provided in a telescopic rod structure, a link hinge structure, or the like. In the present embodiment, the telescopic unit 61 is provided as a link hinge structure. The connecting rod hinge structure is connected with the first adsorption mechanism 30 and the second adsorption mechanism 40 respectively, and the connecting rod hinge structure enables the connecting rod hinge structure to stretch or retract under the action of the tensile force or the compression force of the fourth driving piece, so that the second adsorption mechanism 40 is driven to move relative to the first adsorption mechanism 30. Here, the link hinge structure includes a plurality of link members connected to each other in a hinge manner. The mutual rotation between the connecting rods can realize the extension or retraction movement.

As shown in fig. 2 or fig. 5, the adjusting mechanism 60 further includes a first connecting seat 62 and a second connecting seat 63, which are fixed on the first base 31, and a second connecting seat 63, which is fixed on the second base 41, and the telescopic unit 61 is disposed on the first connecting seat 62 and the second connecting seat 63, and is connected to the first connecting seat 62 and the second connecting seat 63, respectively, so as to realize connection between the telescopic unit 61 and the first adsorption mechanism 30 and the second adsorption mechanism 40.

As shown in fig. 1, the paper film laminating apparatus 100 further includes a board transfer mechanism 70, and the board transfer mechanism 70 is disposed on one side of the base 10, for transferring the board 101 to a predetermined station to perform lamination with the film 102 at the predetermined station.

In one embodiment, the board transfer mechanism 70 is provided with a conveyor belt structure, and the board 101 is placed on the conveyor belt 71 and is conveyed forward by the conveyor belt 71. Of course, the board transport mechanism 70 is not limited to the conveyor structure, and may be provided in other structures capable of achieving board (material) transport.

Further, before the paper board 101 is conveyed to the predetermined station, the paper board 101 needs to be glued, so that when the paper board 101 is conveyed to the predetermined station, the first adsorption mechanism 30 and the second adsorption mechanism 40 respectively drive the two ends of the film 102 to adhere to the paper board 101, that is, the lamination between the paper board 101 and the film 102 is realized.

Here, the cardboard gluing is based on a cylinder transfer principle, glue is transferred onto the cardboard 101 through a glue strip on a gluing cylinder (not shown), and only a glue strip (including a length and/or a width) suitable for the size of the cardboard 101 needs to be attached to the gluing cylinder, and in the process of rotating the gluing cylinder, the glue strip is glued through a glue groove, so that partial coating of the glue can be realized, and further the cardboard 101 has a glue for realizing partial coating of the film 102 and the cardboard 101, and a part of the cardboard 101, which is not glued, is in a separated state from the film 102. The lamination of the paper board 101 and the film 102 means that after the paper board 101 is glued, the paper board is continuously conveyed by the paper board conveying mechanism 70, when the paper board 101 is conveyed to a preset station, the first adsorption mechanism 30 and the second adsorption mechanism 40 drive the two ends of the film 102 to be adhered to the gluing area of the paper board 101 respectively, and the film winding mechanism 50 also completes the release of the rolled film (the part is not adhered to the glue) at the moment, so that the structure shown in fig. 8 is presented.

As shown in fig. 1 or 2, the paper film laminating apparatus 100 may further include a slitting mechanism 80, wherein the slitting mechanism 80 is configured to sever the film 102 when the film fed by the film feeding mechanism 20 reaches a predetermined length, so that the first and second adsorption mechanisms 30 and 40 can laminate the severed film on the board 101. It will be appreciated that by providing the slitting mechanism 80, it is possible to slit the film according to the required length of the film 102, so that the lamination of different cardboard to film ratios can be accurately satisfied in real time according to actual requirements. It should be understood that, in the paper film laminating apparatus 100, the slitting mechanism 80 may be omitted, and if the slitting mechanism 80 is omitted, the film 102 conveyed on the film conveying mechanism 20 may be configured as a film segment by segment, so that the first adsorbing mechanism 30 and the second adsorbing mechanism 40 drive the film segment to move toward the paper board 101.

In one embodiment, the slitting mechanism 80 is disposed between the paperboard conveying mechanism 70 and the base 10; in a direction perpendicular to the base 10, the slitting mechanism 80 is located between the film feeding mechanism 20 and the second adsorbing mechanism 40.

Specifically, the slitting mechanism 80 includes a slitting knife 81 and a drive member (not shown) for the slitting knife 81 that is coupled to the slitting knife 81 and is capable of driving the slitting knife 81 to move relative to the second suction mechanism 40 to sever the film 102 in place.

As shown in fig. 5 and 6, the paper film laminating apparatus 100 further includes a film collecting mechanism 90, and the film collecting mechanism 90 and the film feeding mechanism 20 are disposed at an interval. The film collecting mechanism 90 is used for collecting the film 102 conveyed by the film conveying mechanism 20. That is, the free end 103 of the film 102 is received by the film receiving mechanism 90 during the film deposition by the film feeding mechanism 20, and the film receiving mechanism 90 continuously receives the film released by the film feeding mechanism 20 during the film deposition by the film feeding mechanism 20. It will be appreciated that the film collecting mechanism 90 is provided to collect the film conveyed by the film conveying mechanism 20, so as to avoid the film from being excessively long and scattered and avoid the film from affecting the operation of other mechanisms.

The film winding mechanism 50 is disposed between the film feeding mechanism 20 and the film collecting mechanism 90 and rotatably mounted on the base 10, and is configured to acquire the film 102 located between the film feeding mechanism 20 and the film collecting mechanism 90, and wind up the film 102 on the film feeding mechanism 20 and the film collecting mechanism 90. The first adsorption mechanism 30 is located between the film collecting mechanism 90 and the film rolling mechanism 50. The film winding mechanism 50 is rotatably mounted on the first suction mechanism 30 to acquire the film 102 between the first suction mechanism 30 and the second suction mechanism 40.

As shown in fig. 5, in an embodiment, the film collecting mechanism 90 includes a film collecting plate 91, where the film collecting plate 91 is mounted on the base 10 or the first adsorption mechanism 30 for collecting the film 102. Specifically, the film collecting plate 91 is provided with a film collecting groove 92, and the notch of the film collecting groove 92 is arranged towards the film feeding mechanism 20, so that the free end 103 of the film can be contained in the film collecting groove, and the film continuously fed by the film feeding mechanism 20 is also stored in the film collecting groove 92. When the film winding mechanism 50 starts winding the film, the film in the film winding groove 92 and the film on the film feeding mechanism 20 are wound by the film winding mechanism 50, and the slitting mechanism 80 cuts the film after the winding length reaches a predetermined length.

As shown in fig. 6, in one embodiment, the film take-up mechanism 90 is provided as a rotary type. The film collecting mechanism 90 includes a second rotating member 93 and a fifth driving member (not shown), and the second rotating member 93 is rotatably disposed and is capable of collecting the film 102 conveyed by the film conveying mechanism 20; the fifth driving member is connected to the second rotating member 93, and is used for driving the second rotating member 93 to rotate, so as to realize rolling of the film. By arranging the second rotating member 93, the film released by the film feeding mechanism 20 can be rolled up, so that the film is prevented from being scattered due to overlong film; meanwhile, in the process of winding the film 102 by the film winding mechanism 50, the second rotating member 93 and the film feeding mechanism 20 are positioned so that the two ends of the film 102 are always in a tensioning state, and thus dislocation can occur in the winding process of the film winding mechanism 50.

The lamination process between the cardboard 101 and the film 102 of the present application will be described below with reference to the drawings.

As shown in fig. 2 and 3, when the film collecting mechanism 90 is not provided, the lamination process between the paper board 101 and the film 102 is: cardboard is cut, cardboard rubber coating, is carried cardboard, send membrane mechanism to send the membrane, first adsorption mechanism adsorbs the film, roll up membrane mechanism and roll up the membrane, roll up membrane mechanism and release the film, second adsorption mechanism adsorbs the film, cut the film and paper membrane laminating. Here, cardboard cutting refers to cutting paper or cardboard 101 into sheets of a desired size. The gluing of the paperboard refers to gluing treatment in a gluing area of the paperboard. Conveying the sheet refers to conveying the sheet using the sheet conveying mechanism 70. The film feeding mechanism feeds the film, and the film feeding mechanism feeds the film. The first adsorption mechanism adsorbs the film, which means that the free end of the film (the end of the film near the base) is adsorbed by the first adsorption mechanism. The film rolling mechanism rolls the film, which means that the film rolling mechanism rolls the film. The film releasing of the film winding mechanism means that the film winding mechanism releases the film wound by the film winding mechanism when the first adsorption mechanism and the second adsorption mechanism drive the two ends of the film to move towards the paper board respectively. The second adsorption mechanism adsorbs the film, namely, the film close to one end of the film feeding mechanism is adsorbed by the second adsorption mechanism. Slitting the film is performed by slitting the film using slitting mechanism 80. Paper film lamination refers to laminating a paperboard and a film member.

Specifically, the cardboard is slit and the slit cardboard is glued, and then the glued cardboard is placed at intervals on the cardboard conveying mechanism 70 to be conveyed to a predetermined position. Meanwhile, the film feeding mechanism 20 feeds the film, the free end of the film is adsorbed by the first adsorption mechanism 30, and at this time, the film feeding mechanism 20 continues feeding the film. When the conveyed film reaches the preset length, the film winding mechanism 50 acquires the film between the first adsorption mechanism 30 and the second adsorption mechanism 40 and winds up the film, and the film feeding mechanism 20 continues to feed the film during winding up. During the process of winding the film winding mechanism 50, when the free end of the film is tensioned, the second adsorption mechanism 40 adsorbs one end of the film 102 close to the film feeding mechanism 20, and then the slitting mechanism 80 is controlled to cut the film. Then, the first adsorption mechanism 30 drives the free end 103 of the film, the second adsorption mechanism 40 drives one end of the film 102, which is close to the film feeding mechanism 20, to move towards the direction of the paperboard conveying mechanism 70, and the film winding mechanism 50 simultaneously releases the film, and at a preset position, the two ends of the film are bonded with the glued areas on the paperboard, and after bonding, the first adsorption mechanism 30 and the second adsorption mechanism 40 release the film, so that the lamination between the film 102 and the paperboard 101 is completed. It should be noted that, before the film winding mechanism 50 winds up the film 102, the first adsorption mechanism 30 may not adsorb the free end 103 of the film, that is, may naturally hang the film. The first adsorption mechanism 30 may adsorb the film when the free end of the film 102 reaches the adsorption position of the first adsorption mechanism 30 after the film winding mechanism 50 winds up the film 102.

As shown in fig. 5, when the film collecting mechanism 90 is provided, the lamination process between the cardboard 101 and the film 102 is as follows: when the film collecting mechanism 90 is set as the film collecting plate 91, the lamination process between the paper board 101 and the film 102 is the same as the process in fig. 3, and will not be described herein.

As shown in fig. 6 and 7, when the film collecting mechanism 90 is set as the second rotating member 93, the paper board is cut, the paper board is glued, the paper board is conveyed, the film is sent by the film sending mechanism, the film is absorbed by the first absorbing mechanism, the film is rolled by the film rolling mechanism, the film is released by the film rolling mechanism, the film is absorbed by the second absorbing mechanism, the film is collected by the film collecting mechanism, the film is cut, and the paper film is covered. Here, the film collecting mechanism collects the film, and the film feeding mechanism feeds the film.

Specifically, the lamination process between the cardboard 101 and the film 102 is as follows: the cardboard is slit and the slit cardboard is glued, and then the glued cardboard is placed at intervals on the cardboard conveying mechanism 70 to be conveyed to a predetermined position. At the same time, the film feeding mechanism 20 feeds the film, and the second rotating member 93 receives the film fed continuously by the film feeding mechanism 20. When the conveyed film reaches the preset length, the film winding mechanism 50 acquires the film between the first adsorption mechanism 30 and the second adsorption mechanism 40 and winds up the film, and the film feeding mechanism 20 continues to feed the film in the winding process, and the second rotating member 93 continues to unwind the film. In the process of winding the film winding mechanism 50, when the film on the second rotating member 93 is released, the first adsorption mechanism 30 adsorbs the free end 103 of the film, the second adsorption mechanism 40 adsorbs one end of the film 102 close to the film feeding mechanism 20, and then the slitting mechanism 80 is controlled to cut the film. Then, the first adsorption mechanism 30 drives the free end 103 of the film, the second adsorption mechanism 40 drives one end of the film 102, which is close to the film feeding mechanism 20, to move towards the direction of the paperboard conveying mechanism 70, and the film winding mechanism 50 simultaneously releases the film, and at a preset position, the two ends of the film are bonded with the glued areas on the paperboard, and after bonding, the first adsorption mechanism 30 and the second adsorption mechanism 40 release the film, so that the lamination between the film 102 and the paperboard 101 is completed.

As shown in fig. 9, in an embodiment, the present application further provides a film wrapping paper film laminating method, and the method is applied to the paper film laminating apparatus 100, that is, implemented based on the paper film laminating apparatus 100. The specific structure of the paper laminating apparatus 100 may be referred to in the preamble, and the detailed description thereof will not be repeated here. Specifically, the paper film laminating method of the film package comprises the following steps:

s210, providing a paperboard;

s220, controlling a film feeding mechanism to feed a film;

s230, receiving the film conveyed by the film conveying mechanism through the film receiving mechanism;

s240, controlling a film rolling mechanism to obtain a film positioned between the film feeding mechanism and the film collecting mechanism and rolling the film;

s250, controlling one end of the first adsorption mechanism, which is close to the film collecting mechanism, to adsorb the film;

s260, controlling the second adsorption mechanism to adsorb one end of the film close to the film feeding mechanism;

s270, controlling the first adsorption mechanism and the second adsorption mechanism to respectively drive the corresponding end parts of the film to move towards the paper board, and enabling the two ends of the film to be attached to the paper board; and the film winding mechanism simultaneously releases the wound film in the moving process of the first adsorption mechanism and the second adsorption mechanism.

It can be understood that the film is obtained and rolled up through the film rolling mechanism, namely, the film rolling mechanism can roll up the film with preset length along the length direction of the film, and the preset length can be set according to actual requirements, so that the proportional covering requirements between different paperboards and the film are realized.

There is no order division between steps 210 and 220. Step 210 may be advanced, or step 220 may be advanced; or step 210 and step 220 may be performed simultaneously. In this embodiment, step 210 and step 220 are performed simultaneously. Step 250 and step 260 are not sequentially separated, and step 250 may be performed first, step 260 may be performed first, or step 250 and step 260 may be performed simultaneously.

It should be noted that there is no order between the steps 250 and 230. In the process of conveying the film by the film conveying mechanism in step 220, the first adsorption mechanism may adsorb one end of the film close to the film collecting mechanism, and then step 230 is performed. Of course, it is also possible to execute step 240 and then execute step 250, which is not limited herein.

In one embodiment, step S210 includes the steps of:

s211, cutting a paperboard; namely, the paperboard is cut into preset sizes according to the product packaging requirements.

S212, gluing partial areas of the cut paperboards to form gluing areas; when the film is covered with the paperboard, the film is adhered on the paperboard through glue, so that the film and the paperboard are covered. The glue in this embodiment may be various kinds of glue, such as solid glue, double-sided glue, and the like. The coating between the film and the cardboard is not limited to this.

S213, conveying the glued paper board. The cardboard after gluing is conveyed to a preset position by a cardboard conveying mechanism so as to be covered with a film at the preset position.

In step 220, the film conveyed by the film conveying mechanism passes through the second adsorption mechanism and the first adsorption mechanism, so that the second adsorption mechanism and the first adsorption mechanism can adsorb the film in the subsequent steps. In this embodiment, the film conveyed by the film conveying mechanism passes through the second adsorption mechanism and the first adsorption mechanism in sequence.

In one embodiment, the film collecting mechanism is provided as a rotary type, and the specific structure thereof can be referred to in the description of the foregoing section. Under this structure, step 230 includes the steps of:

s231, the film collecting mechanism picks up the free end of the film conveyed by the film conveying mechanism;

and S232, controlling the film collecting mechanism to rotate so as to synchronously collect the film conveyed by the film conveying mechanism.

It can be understood that the film conveyed by the film rolling and conveying mechanism is synchronously rolled in a rotating mode, so that the film is always in a relatively tensioned state, and the film can be conveyed in a preset direction and is conveniently rolled by the film rolling and conveying mechanism.

In one embodiment, the film collecting mechanism is configured as a film collecting plate, and the specific structure of the film collecting plate can be referred to in the description of the previous section. Under this structure, step 230 includes the steps of:

Step 231, the film collecting plate receives the film conveyed by the film conveying mechanism, and stacks the film on the film collecting plate. That is, in this embodiment, the film fed through the film feeding mechanism is directly accommodated in the film collecting plate.

In one embodiment, the method for laminating a film package further comprises the steps of:

s280, adjusting the distance between the first adsorption mechanism and the second adsorption mechanism based on the size of the paper plate and/or the proportion of the paper plate and the film.

It will be appreciated that the distance between the first and second suction mechanisms corresponds to the size (width or length) of the cardboard, and that different distances between the first and second suction mechanisms can accommodate cardboard of different sizes. Therefore, the adjusting mechanism is arranged to adjust the distance between the first adsorption mechanism and the second adsorption mechanism, so that the paper film laminating equipment provided by the application can realize lamination between paper boards of different sizes and films of different sizes. In other words, the production requirement of covering between the paper board and the film in any proportion can be realized. Here, the size of the cardboard may include a length, a width of the cardboard, and the like. The ratio of the cardboard to the film may be a length ratio, a width ratio, etc., and is not limited herein.

s290, controlling a slitting mechanism to slit the film based on the preset length of the film;

further, in step 290, the slitting mechanism slits an end of the film near the film feeding mechanism.

In one embodiment, the step S290 specifically includes the following steps:

s291, acquiring the preset length of the film to be conveyed according to the proportion of the paperboard to the film; that is, the length of the film to be transferred is set according to the ratio of the cardboard to the film, which is the preset length of the film.

S292, slitting the film according to the preset length by a slitting mechanism. Thus, the film with the preset length is obtained, and the preset ratio of the paper board to the film can be obtained after the film and the paper board are covered.

In one embodiment, in step S290, the step of controlling the slitting mechanism to slit the film near the end of the film feeding mechanism includes:

s293, judging whether the first adsorption mechanism adsorbs one end of the film close to the film collecting mechanism;

if yes, controlling the slitting mechanism to slit the film. Otherwise, the slitting mechanism does not act.

In step 293, a motion sensor may be provided on the first adsorption mechanism to detect whether the film is moving to the first adsorption mechanism. When the motion sensor detects that the film moves to the first adsorption mechanism, the first adsorption mechanism can be controlled to adsorb the film.

In another embodiment, as shown in fig. 10, the present application further provides a film wrapping paper film laminating method, and the method is applied to the paper film laminating apparatus 100, that is, implemented based on the paper film laminating apparatus 100. The specific structure of the paper laminating apparatus 100 may be referred to in the preamble, and the detailed description thereof will not be repeated here. Specifically, the paper film laminating method of the film package comprises the following steps:

s310, providing a paperboard;

s320, controlling a film conveying mechanism to convey the film, wherein the film is arranged far away from the overhang of the film conveying mechanism and forms a free end;

s330, controlling a film rolling mechanism to obtain a film between the first adsorption mechanism and the second adsorption machine and rolling the film;

s340, controlling the first adsorption mechanism to adsorb the free end of the film;

s350, controlling the second adsorption mechanism to adsorb one end of the film close to the film feeding mechanism;

s360, controlling the first adsorption mechanism and the second adsorption mechanism to respectively drive the corresponding end parts of the film to move towards the paper board, and enabling the two ends of the film to be attached to the paper board; and the film winding mechanism simultaneously releases the wound film in the moving process of the first adsorption mechanism and the second adsorption mechanism.

It should be noted that the film wrapping method shown in fig. 10 is substantially the same as that in the embodiment shown in fig. 9. Thus, the method steps are the same and will not be repeated here. For example, the steps of step 310 and step 210 are identical. Step 340 is the same as the step 250, etc. The difference is that the film wrapping method of the film package shown in fig. 10 does not have the film collecting step, that is, step S230 is less than the film wrapping method of the film package in the embodiment shown in fig. 9, and in the embodiment shown in fig. 10, after the film is conveyed in step S320 (step 220), the film is naturally suspended, that is, a free end is formed. Accordingly, in step 340, the first adsorption structure adsorbs the free end of the film. In step 320, the film conveyed by the film conveying mechanism passes through the second adsorption mechanism and the first adsorption mechanism, so that the second adsorption mechanism and the first adsorption mechanism can adsorb the film in the subsequent steps. In this embodiment, the film conveyed by the film conveying mechanism passes through the second adsorption mechanism and the first adsorption mechanism in sequence.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples represent only a few embodiments of the present application, which are described in more detail and are not thereby to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
