[0045] As shown in the figure, Figures 7 to 11 The glue coating and film coating frame 103 is a square frame body welded by square tubes, the glue coating and film coating frame 103 is provided with a paperboard transfer mechanism and a film transfer mechanism located below the paperboard transfer mechanism, the paperboard transfer mechanism is used to receive the paperboard 42 conveyed from the conveying table, and the film transfer mechanism is used to unroll the film roll 68 and lay it flat on the film conveying belt for conveying, the film transfer mechanism comprises a film conveying belt 41 and a belt driving mechanism driving the film conveying belt 41 to rotate, the paperboard 42 transfer mechanism comprises oppositely arranged conveying plates 45 and a plate driving mechanism 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 driving the conveying wheels 44 to rotate, and the conveying wheels 44 are provided with conveying grooves 43.

When the film conveying belt 41 covers the frame, a relatively closed space is formed in the frame. The space has an air outlet and an air inlet. The air outlet is communicated with a fan 63 of the glue coating film frame 103. Thus, negative pressure can be formed in the space through air suction of the fan 63, so as to adsorb the film 40 of the film conveying belt 41 and prevent the film 40 from deforming or floating.

[0052] As shown in the figure, the belt drive mechanism includes a belt drive motor 60, a front belt conveying roller 61 and a rear belt conveying roller 62. The front belt conveying roller 61 and the rear belt conveying roller 62 are arranged on the glue coating film frame 103 through the bearing seat 58. The film conveying belt 41 is arranged on the front belt conveying roller 61 and the rear belt conveying roller 62. As a preferred structure of the present application, the film conveying belt 41 is provided with a plurality of belt holes. The glue coating film frame 103 is relatively provided with a conveying side plate 87 and a conveying cross plate 88 to form a square frame. When the film conveying belt 41 covers the frame, a relatively closed space is formed in the frame. The space has an air outlet and an air inlet. The air outlet is communicated with a fan 63 of the glue coating film frame 103. Thus, negative pressure can be formed in the space through air suction of the fan 63, so as to adsorb the film 40 of the film conveying belt 41 and prevent the film 40 from deforming or floating. Figure 4As shown, the film 40 conveying mechanism includes a film roll loading mechanism, which includes a support arm sliding seat 64, a support arm driving mechanism for moving the support arm sliding seat 64, a support arm swinging mechanism for rotating the support arm, 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, the movable support arm 66 is arranged on the support arm sliding seat 64 through the support arm swinging mechanism, and 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 easily loaded 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 are away from each other and open, so that the top cone 67 is separated from the inner hole of the old film roll 68. 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, 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, 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 clamped into the inner hole of the new film roll 68, and the replacement of the film roll 68 is completed.

[0053] Specifically, the support arm driving mechanism includes oppositely arranged support arm guide shafts 69 and support arm lead screws 70, the support arm guide shafts 69 are fixed on the glue coating and film covering frame 103, the support arm sliding seat 64 is in sliding fit with the support arm guide shafts 69, and the support arm sliding seat 64 is provided with adjusting screw holes matched with the support arm lead screws 70, and the end of the support arm lead screw 70 is provided with a hand wheel, so that the relative movement or opposite movement of the support arm sliding seat 64 along the support arm guide shaft 69 can be realized by manually rotating the hand wheel.

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

[0055] As a further preferred structure, the arm guide shaft 69 is provided with a deviation rectification seat plate 75 and a linear motor 76 arranged on the deviation rectification seat plate 75, the linear motor 76 is connected with the arm sliding seat 64. Sometimes the film 40 will deviate when unwinding, so that the deviation rectification structure is arranged to rectify the deviation. When the film 40 deviates, the arm sliding seat 64, the arm lead screw 70 and the film roll 68 are moved together by the linear motor 76 to realize rectification. In the application, the deviation rectification seat plate 75 is fixed with the arm guide shaft 69.

[0056] As a further preferred structure, the arm sliding seat 64 is provided with an unwinding driving 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 with the corresponding cone shaft through bearings, and the unwinding driving 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, the film 40 is easily stretched and deformed when the compression roller pulls the film 40 in the next extrusion process. Therefore, the film 40 needs to be actively unwound by the structure. The unwinding driving 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] As shown in Figure 12 and 13 The compression driving mechanism includes a compression motor 25 and a compression transmission mechanism (not shown in the figure). The compression motor 25 drives the upper compression roller 23 and the lower compression roller 24 to rotate through the compression transmission mechanism.

One end of the connecting rod one 84 is fixed with the shaft end of the cutter shaft 81. The other end of the connecting rod one 84 is fixed with a connecting shaft one. The connecting shaft is connected with the double-head fish eye joint. The other end of the double-head fish eye joint is connected with a connecting shaft two. The connecting shaft two is fixed with the reciprocating shaft 82. Therefore, the periodic up and down movement of the reciprocating shaft 82 is realized through the rotation of the cutter shaft 81 and the linkage of the connecting rod assembly, so as to drive the cutter 83 to cut and reset. The film covered paperboard is cut into a predetermined size when passing through the cutting table 86. Of course, the cutting table 86 is provided with a cutting seam 79 to avoid the cutter 83.
