Description

Technical Field

[0001] The invention relates to a full-automatic paperboard adhesive laminating system. Background Art

[0002] The surface of the laminated printed matter is smoother and brighter due to the extra layer of film (which can be foam film, plastic film, etc.), which not only improves the gloss and fastness of the printed matter and extends the service life of the printed matter, but also plays a protective role in 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. Workers send 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 to make the film fit tightly to the cardboard.

[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 sprockets 8 and the lower lifting sprockets 11. The upper lifting sprocket 8 is installed on the frame 1 through a bearing, and the lower lifting sprocket 11 is installed 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 clamping plate 17 and supported and guided by a linear guide assembly. The clamping plate 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 absorb 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. In the above, the sprocket, motor, suction cup, linear guide 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 plurality 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, and the auxiliary moving seat 31 includes a moving frame and a plurality 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 conveying belt 36. The conveying rollers are installed on the connecting conveying frame 102 through bearing seats, and the cardboard is sent to the gluing mechanism 4 through the connecting conveying belt 36.

[0044] like Figure 6As shown, the glue coating mechanism 4 also includes a glue transfer roller 37, and the glue coating 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 coating drive motor and the glue coating chain transmission structure are both commonly used structures in the mechanical field, and therefore are not described in detail.

[0045] like Figures 7 to 11 As shown, the glue coating and laminating frame 103 is a square frame body welded by 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 plurality 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 groove 43.

[0046] The working principle of the film coating mechanism 5 structure is as follows: the film 40 is conveyed by the film conveying mechanism and flatly spread on the film conveying 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 conveying 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 is slidably matched with the sliding shaft 46. When it is necessary to put the cardboard 42 onto 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 groove 43. The present 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. 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 the present 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 seat 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 driving mechanism includes a wheel driving motor 53 and a driving pulley 54, a transmission belt 55 and a driven wheel assembly arranged on the wheel driving motor 53. The driven wheel assembly includes a tensioning wheel 56, a driven pulley 57, a bearing seat 58 and a rotating shaft 59 matched with the bearing seat 58. The driven pulley 57 and the conveying wheel 44 are respectively fixed at 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 wheel 56. Through the above structure, the rotation of multiple driven pulleys 57 can be realized by driving one wheel driving motor 53, thereby realizing the rotation of multiple conveying wheels 44, because the cardboard 42 needs to be driven to move forward by the rotation of the conveying wheel 44.

[0051] As shown in the figure, the belt driving mechanism includes a belt driving 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 a 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, so that 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 without deformation 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. Through the above-mentioned mechanism, the film roll 68 is easy to load and convenient to replace. When replacing the film roll 68, the support arm driving mechanism drives the support arm sliding seat 64 to move so that the fixed support arm 65 and the movable support arm 66 move away from each other and open, thereby allowing the top cone 67 to escape from the inner hole of the old film roll 68, and then the support 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 support 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 which 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 is slidably matched with the support arm guide shaft 69, and the support arm sliding seat 64 is provided with an adjustment screw hole which cooperates with the support arm screw rod 70. A hand wheel is installed at the end of the support arm screw rod 70, so that the support arm sliding seat 64 can be driven to move relative to or toward each other along the support arm guide shaft 69 by manually turning the hand wheel.

[0054] The support arm swing mechanism includes a swing cylinder 71 fixed on the support 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 meshes 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, and 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 70 and the film roll 68 to move together to achieve correction. In the present application, the correction seat plate 75 is fixed together with 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 of the next extrusion process pulls the film 40. Therefore, 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 Fig.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 thus 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, and 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 coated cardboard is pressed by the upper pressure roller 23 and the lower pressure roller 24 and cut by the cutter 83. In the above structure, the connecting rod assembly The parts 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, and connecting shaft 2 is fixed to reciprocating shaft 82. Therefore, the periodic up and down movement of reciprocating shaft 82 is realized through the rotation of cutter shaft 81 and the linkage of connecting rod assembly, thereby driving cutter 83 to cut and reset.
