Technical Field

[0001] The invention relates to a paperboard laminating machine, in particular to a paperboard and film bonding mechanism of the laminating machine. 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.

[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. Therefore, the applicant has designed a cardboard laminating machine to solve the above problems. This application is aimed at the cardboard and film bonding mechanism of the laminating machine.

The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.

[0031] Reference Figure 1 , Figure 2 The present invention discloses a laminating machine cardboard and film bonding mechanism, including a frame 1, the frame 1 is a square frame body welded by square tubes, the frame 1 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 cardboard 2 conveyed from a conveying platform, the film conveying mechanism is used to unfold a film roll 8 and lay it flat on a film conveyor belt for conveying, the film conveying mechanism includes a film conveyor belt 3 and a belt driving mechanism for driving the film conveyor belt 3 to rotate, the cardboard 2 transfer mechanism includes a relatively arranged conveying plate 4 and a plate driving mechanism for driving the conveying plate 4 to move, the conveying plate 4 is provided with a plurality of conveying wheels 5 and a wheel driving mechanism for driving the conveying wheel 5 to rotate, and the conveying wheel 5 is provided with a conveying groove 6.

[0032] The working principle of the above structure is:

[0033] The film 7 is conveyed by the film 7 conveying mechanism and spread out flatly on the film conveying belt 3. At the same time, the cardboard 2 coated with glue is conveyed to the cardboard 2 transfer mechanism through the gluing device. The two side edges of the cardboard 2 can be located in the conveying groove 6 and conveyed to the bonding position above the film conveying belt 3 by the rotation of the paper conveying wheel 5. The two conveying plates 4 are relatively separated by the plate driving mechanism to separate the conveying wheel 5 from the cardboard 2, so that the cardboard 2 can fall on the film 7 to achieve preliminary bonding between the cardboard 2 and the film 7.

[0034] like Figure 5 As shown, the plate driving mechanism includes a sliding shaft 9 and a driving seat plate 10 arranged on the frame 1, and a plate driving cylinder 11 is provided on the driving seat plate 10. The plate driving cylinder 11 is connected to the conveying plate 4, and the conveying plate 4 is slidably matched with the sliding shaft 9. When the cardboard 2 needs to be placed on the film conveyor belt 3, the plate driving cylinder 11 will start to push the conveying plate 4 to move backward and open, so that the cardboard 2 falls off from the conveying groove 6. The present application has two parallel conveying plates 4, and there are four plate driving cylinders 11 divided into two groups, each group corresponding to a conveying plate 4.

[0035] As a further structure, the frame 1 is provided with an adjusting screw 12 and an adjusting drive motor 13. The adjusting screw 12 is arranged on the frame 1 through a bearing. The driving seat plate 10 is provided with an adjusting nut that cooperates with the adjusting screw 12. The adjusting drive motor 13 is connected to the adjusting screw 12 through an adjusting transmission structure. The adjusting transmission structure is a sprocket transmission structure 14, which is a common transmission structure in machinery and is not described in detail. Because there are two adjusting screws 12 in the present application and they need to rotate synchronously, the adjusting drive motor 13 drives the two adjusting screws 12 through the sprocket transmission structure 14, and drives the adjusting nut through the adjusting screw 12 to drive the driving seat plate 10 and the conveying plate 4 to move, thereby realizing the opening or closing of the driving seat plate 10 and the conveying plate 4, thereby adapting to cardboards 2 of different width specifications.

[0036] As a further structure, because there is glue on the cardboard 2, in order to prevent the cardboard 2 from moving along when the conveying wheel 5 moves, a positioning baffle 15 is provided on the driving seat plate 10, and the positioning baffle 15 can block the cardboard 2 when the conveying wheel 5 moves.

[0037] As shown in the figure, the wheel drive mechanism includes a wheel drive motor 16 and a driving pulley 17, a transmission belt 18 and a driven wheel assembly arranged on the wheel drive motor 16. The driven wheel assembly includes a tensioning wheel 19, a driven pulley 20, a bearing seat 21 and a rotating shaft 22 matched with the bearing seat 21. The driven pulley 20 and the conveying wheel 5 are respectively fixed to the two ends of the corresponding rotating shaft 22. The transmission belt 18 is arranged on the driving pulley 17, the driven pulley 20 and the tensioning wheel 19. Through the above structure, the rotation of multiple driven pulleys 20 can be realized by driving one wheel drive motor 16, thereby realizing the rotation of multiple conveying wheels 5, because the cardboard 2 needs to be driven to move forward by the rotation of the conveying wheel 5.

[0038] like Figure 3 As shown, the belt driving mechanism includes a belt driving motor 23, a front belt conveying roller 24 and a rear belt conveying roller 25. The front belt conveying roller 24 and the rear belt conveying roller 25 are arranged on the frame 1 through a bearing seat 21, and the film conveying belt 3 is arranged on the front belt conveying roller 24 and the rear belt conveying roller 25. As a preferred structure of the present application, a plurality of belt holes are provided on the film conveying belt 3, and a conveying side plate 26 and a conveying cross plate 27 are relatively provided on the frame 1 to form a square frame. When the film conveying belt 3 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 28 on the frame 1, so that the exhaust of the fan 28 can form a negative pressure in the space, thereby adsorbing the film 7 of the film conveying belt 3 without deformation or floating.

[0039] like Figure 4As shown, the film 7 conveying mechanism includes a film roll 8 feeding mechanism, and the film roll 8 feeding mechanism includes a support arm sliding seat 29, an arm driving mechanism for driving the support arm sliding seat 29 to move, an arm swinging mechanism for driving the support arm to rotate, a fixed support arm 30 and a movable support arm 31, and the fixed support arm 30 and the sliding support arm are arranged on the corresponding support arm sliding seat 29, and the movable support arm 31 is arranged on the support arm sliding seat 29 through the support arm swinging mechanism. The fixed support arm 30 and the movable support arm 31 are both provided with a rotatable top cone 32. Through the above mechanism, the film roll 8 is easy to load, and convenient The support arm 31 is then reset, and the support arm sliding seat 29 drives the fixed support arm 30 and the movable support arm 31 to reset, so that the top cone 32 is stuck in the inner hole of the new film roll 8, and the film roll 8 is replaced.

[0040] Specifically, the support arm driving mechanism includes a support arm guide shaft 33 and an arm screw rod 34 which are relatively arranged. The support arm guide shaft 33 is fixed on the frame 1. The support arm sliding seat 29 is slidably matched with the support arm guide shaft 33, and the support arm sliding seat 29 is provided with an adjustment screw hole which cooperates with the support arm screw rod 34. A hand wheel is installed at the end of the support arm screw rod 34, so that the support arm sliding seat 29 can be driven to move relative to or toward the support arm guide shaft 33 by manually turning the hand wheel.

[0041] The support arm swing mechanism includes a swing cylinder 35 fixed on the support arm sliding seat 29, a swing seat 36, a swing rack 37 fixed to the swing cylinder 35, and a swing gear 38 fixed to the movable support arm 31. The swing gear 38 is arranged in the swing seat 36 through a bearing and meshes with the swing rack 37. Therefore, when the swing cylinder 35 drives the swing rack 37 to move along the swing seat 36 slide groove in the swing seat 36, the movable support arm 31 can be driven to rotate upward through the swing gear 38. The structure of the rack and gear can withstand greater pressure and has good reliability.

[0042] As a further preferred structure, the support arm guide shaft 33 is provided with a correction seat plate 39 and a linear motor 40 arranged on the correction seat plate 39, and the linear motor 40 is connected to the support arm sliding seat 29. Because the film 7 sometimes deflects when unwinding, a correction structure is provided to correct the deflection. When the film 7 deflects, the linear motor 40 drives the support arm sliding seat 29, the support arm screw rod 34 and the film roll 8 to move together to achieve correction. In this application, the correction seat plate 39 is fixed together with the support arm guide shaft 33.

[0043] As a further preferred structure, the support arm sliding seat 29 is provided with an unwinding drive motor 41 and an unwinding transmission structure 42, the top cone 32 is provided with a cone shaft, the fixed support arm 30 and the movable support arm 31 are connected to the corresponding cone shaft through bearings, and the unwinding drive motor 41 can drive the corresponding cone shaft to rotate through the unwinding transmission structure 42. Because the film roll 8 is relatively heavy and the film 7 is relatively thin, it is easy to cause the film 7 to stretch and deform when the pressure roller of the next extrusion process pulls the film 7. Therefore, it is necessary to follow the unwinding through this structure. The unwinding drive motor 41 drives the cone shaft to rotate through the unwinding transmission structure 42, and the cone shaft drives the top cone 32 to rotate, so that the film roll 8 rotates to actively release the film 7.
