Description

Technical Field

[0001] The utility model relates to a cardboard laminating machine. Background Art

[0002] The printed matter after lamination has an extra layer of film (which can be foam film, plastic film, etc.) on the surface, which makes the surface smoother and brighter, not only improving the gloss and fastness of the printed matter and extending the service life of the printed matter, but also the film plays a protective role such as moisture-proof, waterproof, anti-fouling, wear-resistant, fold-resistant, and chemical corrosion-resistant.

[0003] Therefore, cardboard is now covered with a layer of film. Generally, glue is applied to the cardboard manually, and then the film is covered on the glue. The worker sends the cardboard with the film between two rollers, which are driven by a motor to rotate. During the rotation process, the cardboard is not only driven forward, but also the roller can evenly squeeze out the bubbles so that the film fits tightly to the cardboard.

[0004] However, the above process only realizes mechanized automatic operation in the extrusion process, and the rest of the loading, gluing and transportation are all done manually, which cannot realize assembly line production.

[0041] like Figures 2 to 4As shown, the lifting drive unit 7 is a lifting motor, the lifting transmission unit is a sprocket lifting structure, the sprocket lifting structure includes four upper lifting sprockets 8, four lower lifting sprockets 11, and a lifting chain 26 arranged on the upper lifting sprocket 8 and the lower lifting sprocket 11. The upper lifting sprocket 8 is mounted on the frame 1 through a bearing, and the lower lifting sprocket 11 is mounted on the lifting seat 9 through a bearing; the suction cup driving unit 10 is a motor, and the suction cup transmission unit is a belt transmission mechanism driven by the suction cup driving unit 10. The suction cup frame 12 and the conveyor belt 19 of the belt transmission mechanism are fixed by a splint 17 and supported and guided by a linear guide assembly. The splint 17 is locked with the suction cup frame 12 by screws to clamp the conveyor belt 19. The suction cup frame 12 is provided with a suction cup lifting cylinder 27 and The suction cup mounting plate 28 is lifted and lowered by the suction cup lifting cylinder 27, and the suction cup 13 is fixed on the suction cup mounting plate 28. The specific working principle of the above structure is: the cardboards are stacked together and placed on the lifting seat 9, and the suction cup 13 is moved to the top of the cardboard pile 29 by the belt transmission mechanism driven by the suction cup driving unit 10, and then the suction cup lifting cylinder 27 is lowered to make the suction cup 13 adsorb the top cardboard of the cardboard pile 29, and then, the suction cup lifting cylinder 27 is raised to make the suction cup 13 drive the cardboard to rise, and then the suction cup driving unit 10 sends the suction cup 13 and the cardboard to the connecting conveyor belt through the belt transmission mechanism. Among the above, the sprocket, motor, suction cup, linear guide rail assembly and belt transmission mechanism are all existing technical designs, so the specific structure is not described in detail. Of course, the suction cup will be connected to the vacuum generator.

[0042] As a preferred structure, the lifting seat 9 is provided with a number of conveying rollers 30 arranged in a row, and the conveying rollers 30 are connected to the lifting seat 9 through bearings, so as to facilitate the cardboard pile 29 to be pushed onto the lifting seat 9. As a further structure, an auxiliary moving seat 31 is provided at the feeding port of the lifting seat 9. The auxiliary moving seat 31 includes a moving frame and a number of moving rollers 32 arranged in the moving frame. The moving rollers 32 are arranged on the moving frame through bearings, so that the cardboard pile 29 can be pushed into the lifting seat 9 with the assistance of the auxiliary moving seat 31.

[0043] like Figure 5 As shown, the connecting conveying mechanism 3 includes a connecting conveying motor 33, a connecting conveying roller 1 34 and a connecting conveying roller 2 (not shown in the figure). The connecting conveying motor 33 is connected to the connecting conveying roller 1 34 through a belt drive (not shown in the figure) to drive it to rotate. The connecting conveying roller 1 34 and the connecting conveying roller 2 are provided with a connecting conveyor belt 36. The conveying rollers are installed on the connecting conveying frame 102 through bearing seats, and the cardboard is fed into the gluing mechanism 4 through the connecting conveyor belt 36.

[0044] like Figure 6As shown, the gluing mechanism 4 also includes a glue transfer roller 37, and the gluing drive mechanism includes a glue coating motor 38 and a glue coating chain transmission mechanism 39. The glue coating chain transmission mechanism 39 is connected to the glue transfer roller 37, the upper glue roller 15, and the lower glue roller 16 to drive the three to rotate together. The glue transfer roller 37 is located between the lower glue roller 16 and the glue tray 14, and the glue transfer roller 37 can transfer the glue in the glue tray 14 to the lower glue roller 16, so that the glue transferred to the lower glue roller 16 is more uniform and appropriate. The glue driving motor and the glue coating chain transmission structure are both commonly used structures in the mechanical field, and therefore will not be described in detail.

[0045] like Figures 7 to 11 As shown, the glue coating and laminating frame 103 is a square frame welded from square tubes, and the glue coating and laminating frame 103 is provided with a cardboard transfer mechanism and a film conveying mechanism located below the cardboard transfer mechanism, the cardboard transfer mechanism is used to receive the cardboard 42 conveyed from the conveying platform, and the film conveying mechanism is used to unfold the film roll 68 and spread it flat on the film conveyor belt for conveying, the film conveying mechanism includes a film conveyor belt 41 and a belt driving mechanism for driving the film conveyor belt 41 to rotate, the cardboard 42 transfer mechanism includes relatively arranged conveying plates 45 and a plate driving mechanism for driving the conveying plates 45 to move, the conveying plates 45 are provided with a number of conveying wheels 44 and a wheel driving mechanism for driving the conveying wheels 44 to rotate, and the conveying wheels 44 are provided with a conveying trough 43.

[0046] The working principle of the film laminating mechanism 5 is as follows: the film 40 is conveyed by the film conveying mechanism and spread out flatly on the film conveyor belt 41, and at the same time, the cardboard 42 coated with glue is conveyed to the cardboard 42 transfer mechanism through the gluing device, and the two side edges of the cardboard 42 can be located in the conveying groove 43 and conveyed to the bonding position above the film conveyor belt 41 by the rotation of the conveying wheel 44, and the two conveying plates 45 are relatively separated by the plate driving mechanism to separate the conveying wheel 44 from the cardboard 42, so that the cardboard 42 can fall on the film 40 to achieve preliminary bonding between the cardboard 42 and the film 40.

[0047] As shown in the figure, the plate driving mechanism includes a sliding shaft 46 and a driving seat plate 47 arranged on the glue coating and film laminating frame 103. The driving seat plate 47 is provided with a plate driving cylinder 48. The plate driving cylinder 48 is connected to the conveying plate 45, and the conveying plate 45 slides with the sliding shaft 46. When the cardboard 42 needs to be placed on the film conveyor belt 41, the plate driving cylinder 48 will start to push the conveying plate 45 to move backward and open, so that the cardboard 42 falls off from the conveying trough 43. This application has two parallel conveying plates 45, and there are four plate driving cylinders 48 divided into two groups, each group corresponding to a conveying plate 45.

[0048] As a further structure, the glue coating and laminating frame 103 is provided with an adjusting screw 49 and an adjusting drive motor 50. The adjusting screw 49 is arranged on the glue coating and laminating frame 103 through a bearing, and the driving seat plate 47 is provided with an adjusting nut that cooperates with the adjusting screw 49. The adjusting drive motor 50 is connected to the adjusting screw 49 through an adjusting transmission structure. The adjusting transmission structure is a sprocket transmission structure 51, which is a common transmission structure in machinery and is not described in detail. Because there are two adjusting screws 49 in this application and they need to rotate synchronously, the adjusting drive motor 50 drives the two adjusting screws 49 through the sprocket transmission structure 51, and drives the adjusting nut through the adjusting screw 49 to drive the driving seat plate 47 and the conveying plate 45 to move, thereby realizing the opening or closing of the driving seat plate 47 and the conveying plate 45, thereby adapting to cardboards 42 of different width specifications.

[0049] As a further structure, because there is glue on the cardboard 42, in order to prevent the cardboard 42 from moving with the conveying wheel 44, a positioning baffle 52 is provided on the driving base plate 47, and the positioning baffle 52 can block the cardboard 42 when the conveying wheel 44 moves.

[0050] As shown in the figure, the wheel drive mechanism includes a wheel drive motor 53 and a driving pulley 54, a transmission belt 55 and a driven wheel assembly arranged on the wheel drive motor 53. The driven wheel assembly includes a tensioning pulley 56, a driven pulley 57, a bearing seat 58 and a rotating shaft 59 cooperating with the bearing seat 58. The driven pulley 57 and the conveying wheel 44 are respectively fixed to the two ends of the corresponding rotating shaft 59. The transmission belt 55 is arranged on the driving pulley 54, the driven pulley 57 and the tensioning pulley 56. Through the above structure, the rotation of multiple driven pulleys 57 can be realized by driving one wheel drive motor 53, thereby realizing the rotation of multiple conveying wheels 44, because the cardboard 42 needs to be driven forward by the rotation of the conveying wheel 44.

[0051] As shown in the figure, the belt drive mechanism includes a belt drive motor 60, a front belt conveyor roller 61 and a rear belt conveyor roller 62. The front belt conveyor roller 61 and the rear belt conveyor roller 62 are arranged on the glue coating and laminating frame 103 through a bearing seat 58. The film conveyor belt 41 is arranged on the front belt conveyor roller 61 and the rear belt conveyor roller 62. As the preferred structure of the present application, a plurality of belt holes are provided on the film conveyor belt 41, and the glue coating and laminating frame 103 is relatively provided with conveying side plates 87 and conveying cross plates 88 to form a square frame. When the film conveyor belt 41 covers the frame, a relatively closed space is formed in the frame. The space has an exhaust port and an air inlet. The exhaust port is connected to the fan 63 of the glue coating and laminating frame 103. In this way, the exhaust of the fan 63 can form a negative pressure in the space, thereby adsorbing the film 40 of the film conveyor belt 41 and preventing it from deforming or floating.

[0052] like Figure 4As shown, the film 40 conveying mechanism includes a film roll loading mechanism, and the film roll loading mechanism includes a support arm sliding seat 64, an arm driving mechanism for driving the support arm sliding seat 64 to move, an arm swinging mechanism for driving the support arm to rotate, a fixed support arm 65 and a movable support arm 66, and the fixed support arm 65 and the sliding support arm are arranged on the corresponding support arm sliding seat 64, and the movable support arm 66 is arranged on the support arm sliding seat 64 through the support arm swinging mechanism. The fixed support arm 65 and the movable support arm 66 are both provided with a rotatable top cone 67, and the film roll 68 is easy to load and convenient to replace through the above mechanism. When the film roll 68 is replaced, the arm driving mechanism drives the arm sliding seat 64 to move, so that the fixed support arm 65 and the movable support arm 66 move away and open, so that the top cone 67 is disengaged from the inner hole of the old film roll 68, and then the arm swinging mechanism drives the movable support arm 66 to swing upward to avoid the feeding position of the new film roll 68, and then the old film roll 68 is taken out, and the new film roll 68 is put in from the side of the movable support arm 66, and then the movable support arm 66 is reset, and the arm sliding seat 64 drives the fixed support arm 65 and the movable support arm 66 to reset, so that the top cone 67 is stuck in the inner hole of the new film roll 68, completing the replacement of the film roll 68.

[0053] Specifically, the support arm driving mechanism includes a support arm guide shaft 69 and a support arm screw rod 70 that are relatively arranged. The support arm guide shaft 69 is fixed on the glue coating and laminating frame 103. The support arm sliding seat 64 slides with the support arm guide shaft 69, and the support arm sliding seat 64 is provided with an adjustment screw hole that cooperates with the support arm screw rod 70. The end of the support arm screw rod 70 is equipped with a handwheel, so that by manually turning the handwheel, the support arm sliding seat 64 can be driven to move relative to or toward the support arm guide shaft 69.

[0054] The arm swing mechanism includes a swing cylinder 71 fixed on the arm sliding seat 64, a swing seat 72, a swing rack 73 fixed to the swing cylinder 71, and a swing gear 74 fixed to the movable support arm 66. The swing gear 74 is arranged in the swing seat 72 through a bearing and engages with the swing rack 73. Therefore, when the swing cylinder 71 drives the swing rack 73 to move along the swing seat 72 slide groove in the swing seat 72, the movable support arm 66 can be driven to rotate upward through the swing gear 74. The structure of the rack and gear can withstand greater pressure and has good reliability.

[0055] As a further preferred structure, the support arm guide shaft 69 is provided with a correction seat plate 75 and a linear motor 76 arranged on the correction seat plate 75. The linear motor 76 is connected to the support arm sliding seat 64. Because sometimes the film 40 will deflect when unwinding, a correction structure is provided to correct the deflection. When the film 40 deflects, the linear motor 76 drives the support arm sliding seat 64, the support arm screw rod 70 and the film roll 68 to move together to achieve correction. In this application, the correction seat plate 75 is fixed to the support arm guide shaft 69.

[0056] As a further preferred structure, the support arm sliding seat 64 is provided with an unwinding drive motor 77 and an unwinding transmission structure 78, the top cone 67 is provided with a cone shaft, the fixed support arm 65 and the movable support arm 66 are connected to the corresponding cone shaft through bearings, and the unwinding drive motor 77 can drive the corresponding cone shaft to rotate through the unwinding transmission structure 78. Because the film roll 68 is relatively heavy and the film 40 is relatively thin, it is easy to cause the film 40 to stretch and deform when the pressure roller in the next extrusion process pulls the film 40, so it is necessary to follow the unwinding through this structure. The unwinding drive motor 77 drives the cone shaft to rotate through the unwinding transmission structure 78, and the cone shaft drives the top cone 67 to rotate, so that the film roll 68 rotates to actively release the film 40.

[0057] like Figure 12 and 13 As shown, the pressing drive mechanism includes a pressing motor 25 and a pressing transmission mechanism (not shown in the figure), and the pressing motor 25 drives the upper pressing roller 23 and the lower pressing roller 24 to rotate at the same time through the pressing transmission mechanism. The pressing transmission mechanism is a chain transmission mechanism, which is a prior art, and therefore the specific structure is not described in detail. The upper pressing roller 23 and the lower pressing roller 24 are arranged on the glue coating and laminating frame 103 through a bearing seat, and the synchronous transmission of the upper pressing roller 23 and the lower pressing roller 24 is achieved through the above structure. The pressing transmission mechanism is a chain transmission structure, which is a prior art and is not described in detail.

[0058] As shown in the figure, it also includes a cutter mechanism, which includes a cutter motor 80, a cutter shaft 81, a reciprocating shaft 82, a connecting rod assembly, and a cutter 83. The cutter 83 motor 80 drives the cutter 83 shaft 81 to rotate through a chain transmission mechanism. The cutter shaft 81 is installed on the glue coating and laminating frame 103 through a bearing seat. When the cutter 83 shaft 81 rotates, it drives the cutter 83 shaft 81 to be fixedly connected to the connecting rod assembly, and the reciprocating shaft 82 is rotatably connected to the connecting rod assembly. The cutter 83 shaft 81 drives the reciprocating shaft 82 to move up and down through the connecting rod assembly, and the upper pressure roller 23 and the lower pressure roller 24 press the coated cardboard to be cut by the cutter 83. In the above structure, the connecting rod assembly The components include connecting rod 1 84 and connecting rod 2 85. Connecting rod 2 85 is preferably a double-headed fisheye joint. One end of connecting rod 1 84 is fixed to the axial end of cutter shaft 81, and the other end of connecting rod 1 84 is fixed with connecting shaft 1, which is connected to the double-headed fisheye joint, and the other end of the double-headed fisheye joint is connected to connecting shaft 2, which is fixed to reciprocating shaft 82. Therefore, the reciprocating shaft 82 is periodically moved up and down by the rotation of cutter shaft 81 and the linkage of connecting rod assembly, thereby driving cutter 83 to cut and reset. When the coated cardboard passes through cutting table 86, it is cut into predetermined size by cutter 83. Of course, cutting table 86 is provided with cutting slot 79 to avoid cutter 83.
