[0030] As a person skilled in the art can fully understand, the features of different embodiments of the present disclosure can be partially or wholly coupled or combined with each other, and can be cooperated with each other in various ways and technically driven. Embodiments of the present disclosure can be executed independently of each other, or can be executed together in a mutually dependent relationship.

[0031] Referring to Figure 1 , Figure 2 , the present application discloses a kind of film laminating machine paperboard and film bonding mechanism, including frame 1, frame 1 is square frame body welded into square tube, paperboard transfer mechanism and the film conveying mechanism located below paperboard transfer mechanism are equipped on the frame 1, paperboard transfer mechanism is used to receive the paperboard 2 conveyed from conveying table, film conveying mechanism is used to unroll and lay flat to film conveying belt and transport film roll 8, the film conveying mechanism includes film conveying belt 3 and the drive mechanism of belt drive film conveying belt 3 rotation, the paperboard 2 transfer mechanism includes oppositely arranged conveying plate 4 and the plate drive mechanism of conveying plate 4 movement, the conveying plate 4 is equipped with a plurality of conveying wheels 5 and the wheel drive mechanism of conveying wheel 5 rotation, the conveying wheel 5 is equipped with conveying groove 6.

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

[0033] Film 7 is transported and evenly expanded on film conveying belt 3 by film 7 conveying mechanism, and paperboard 2 coated with glue is conveyed to paperboard 2 transfer mechanism by gluing device, the two side edges of paperboard 2 can be located in conveying groove 6 and conveyed to the bonding position above film conveying belt 3 by the rotation of paper conveying wheel 5, and the two conveying plates 4 are relatively separated by the plate drive mechanism to make conveying wheel 5 and paperboard 2 separate, so that paperboard 2 can fall on film 7 to realize the preliminary bonding of paperboard 2 and film 7.

[0034] As Figure 5 shown, the plate drive mechanism includes slide shaft 9 arranged on frame 1 and drive base plate 10, the drive base plate 10 is equipped with plate drive cylinder 11, the plate drive cylinder 11 is connected with the conveying plate 4, and the conveying plate 4 is in sliding fit with the slide shaft 9, when it is needed to put paperboard 2 on film conveying belt 3, the plate drive cylinder 11 will start to push the conveying plate 4 to move away from each other to open, so that paperboard 2 falls out of conveying groove 6, the present application has two parallel conveying plates 4, the plate drive cylinder 11 has four groups, each group corresponds to one conveying plate 4.

[0035] As a further structural feature, the frame 1 is equipped with an adjusting screw 12 and an adjusting drive motor 13. The adjusting screw 12 is mounted on the frame 1 via bearings. The drive base plate 10 is equipped with an adjusting nut that cooperates with the adjusting screw 12. The adjusting drive motor 13 is connected to the adjusting screw 12 via an adjusting transmission structure, which is a sprocket transmission structure 14. This structure is a common transmission structure in machinery, so it will not be described in detail. Since there are two adjusting screws 12 in this application and they need to rotate synchronously, the adjusting drive motor 13 drives the two adjusting screws 12 through the sprocket transmission structure 14. The adjusting screws 12 drive the adjusting nut, which in turn drives the drive base plate 10 and the conveyor plate 4 to move, thereby opening or closing the drive base plate 10 and the conveyor plate 4 to accommodate cardboard 2 of different widths.

[0036] As a further structure, since there is glue on the cardboard 2, in order to prevent the cardboard 2 from moving along with the conveyor wheel 5, the drive base plate 10 is provided with a positioning baffle 15, which can block the cardboard 2 when the conveyor wheel 5 moves.

[0037] As shown in the figure, the wheel drive mechanism includes a wheel drive motor 16, a drive pulley 17, a transmission belt 18, and a driven wheel assembly mounted on the wheel drive motor 16. The driven wheel assembly includes a tension wheel 19, a driven pulley 20, a bearing seat 21, and a rotating shaft 22 that cooperates with the bearing seat 21. The driven pulley 20 and the conveying wheel 5 are respectively fixed at both ends of the corresponding rotating shaft 22. The transmission belt 18 is mounted on the drive pulley 17, the driven pulley 20, and the tension pulley 19. With the above structure, the rotation of multiple driven pulleys 20 can be achieved by driving one wheel drive motor 16, thereby achieving the rotation of multiple conveying wheels 5, because the cardboard 2 needs to be driven forward by the rotation of the conveying wheels 5.

[0038] like Figure 3 As shown, the belt drive mechanism includes a belt drive motor 23, a front belt conveyor roller 24, and a rear belt conveyor roller 25. The front belt conveyor roller 24 and the rear belt conveyor roller 25 are mounted on the frame 1 via bearing seats 21. The membrane conveyor belt 3 is mounted on the front belt conveyor roller 24 and the rear belt conveyor roller 25. As a preferred structure of this application, the membrane conveyor belt 3 is provided with several belt holes, and the frame 1 is provided with a conveyor side plate 26 and a conveyor cross plate 27 to form a square frame. When the membrane conveyor belt 3 covers the frame, a relatively closed space is formed in the frame. This space has an exhaust port and an air inlet. The exhaust port is connected to a fan 28 on the frame 1. In this way, the exhaust of the fan 28 can create a negative pressure in the space, thereby adsorbing the membrane 7 of the membrane conveyor belt 3 so that it will not deform or float.

[0039] like Figure 4As shown, the film 7 conveying mechanism includes a film roll 8 loading mechanism, which includes a support arm sliding seat 29, a support arm driving mechanism for moving the support arm sliding seat 29, a support arm swinging mechanism for rotating the support arm, 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, the movable support arm 31 is arranged on the support arm sliding seat 29 through the support arm swinging mechanism, and the fixed support arm 30 and the movable support arm 31 are both provided with a rotatable top cone 32. Through the above-mentioned mechanism, the film roll 8 is easily loaded and conveniently replaced. When the film roll 8 is replaced, the support arm driving mechanism drives the support arm sliding seat 29 to move so that the fixed support arm 30 and the movable support arm 31 are away from each other and are opened, so that the top cone 32 is separated from the inner hole of the old film roll 8. Then the support arm swinging mechanism drives the movable support arm 31 to swing upward to avoid the feeding position of the new film roll 8. Then the old film roll 8 is taken out, the new film roll 8 is put in from the side of the movable support arm 31, then the movable support arm 31 is reset, 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 clamped into the inner hole of the new film roll 8, and the replacement of the film roll 8 is completed.

[0040] Specifically, the support arm driving mechanism includes oppositely arranged support arm guide shafts 33 and support arm lead screws 34, the support arm guide shafts 33 are fixed on the rack 1, the support arm sliding seat 29 is in sliding fit with the support arm guide shafts 33, and the support arm sliding seat 29 is provided with adjusting screw holes matched with the support arm lead screws 34, and the end of the support arm lead screw 34 is provided with a hand wheel, so that the relative movement or the opposite movement of the support arm sliding seat 29 along the support arm guide shaft 33 can be realized by manually rotating the hand wheel.

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

[0042] As a further preferred structure, the support arm guide shaft 33 is provided with a deviation rectification seat plate 39 and a linear motor 40 arranged on the deviation rectification seat plate 39, and the linear motor 40 is connected with the support arm sliding seat 29. Sometimes the film 7 will deviate when it is unwound, so a deviation rectification structure is arranged to rectify the deviation. When the film 7 deviates, the linear motor 40 drives the support arm sliding seat 29, the support arm lead screw 34 and the film roll 8 to move together to realize rectification. In this application, the deviation rectification seat plate 39 is fixed with the support arm guide shaft 33.

[0043] As a further preferred structure, the branch arm sliding seat 29 is provided with a unwinding driving motor 41 and a 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 with the corresponding cone shaft through bearings, and the unwinding driving 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 light and thin, the film 7 is prone to stretch and deform when the pressure roller pulls the film 7 in the next extrusion process. Therefore, the film 7 needs to be actively unwound by the film roll 8. The unwinding driving 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.

The above description of the embodiments is only used to help understand the method of the present application and its core idea. Meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation modes and application ranges will be changed, and the above description should not be understood as a limitation of the present application.
