[0040] The forming die 2 is used for preliminary forming, so it needs to dip slurry. In this embodiment, the forming die 2 further comprises a forming cylinder 23 arranged on the upper side of the slurry pool 1 through a support, the piston rod of the forming cylinder 23 is connected with a first movable beam 24 moving up and down, the first forming die 21 and the second forming die 22 are located at the lower side of the first movable beam 24, the upper side of the first movable beam 24 is provided with a first guide rail 25, the two ends of the first forming die 21 and the second forming die 22 are connected with the first guide rail 25 through a first sliding side plate 26 and a sliding block, and the first movable beam 24 is respectively provided with a first forming cylinder 23 and a second forming cylinder 23 for driving the first forming die 21 and the second forming die 22 to move.

After hot-pressing is completed, the paper-plastic bottle can be taken out from the position of the forming chassis 3, and then removed through the material taking structure 6.
[0042] Further, the first hot-pressing die 51 and the second hot-pressing die 52 are respectively provided with a heating plate 57 for heating the first hot-pressing die 51 and the second hot-pressing die 52.

The heating plate is provided with a heating structure such as an electric heating wire, and is connected with a power supply for forming the heating plate.
[0043] The forming base frame 3 is used for the internal forming of the paper-plastic bottle, and supports the paper-plastic bottle during the transferring process. Therefore, in the present embodiment, the forming base frame 3 comprises a transverse bottom plate 32 arranged by a first transverse moving structure 33, which moves between the forming die 2 and the hot-pressing die 5 under the action of the first transverse moving structure 33.

An air inflation cavity is arranged on the upper side of the forming bottom plate 34. The air bag 31 is arranged on the upper side of the forming bottom plate 34 and communicates with the air inflation cavity. The length of the transverse bottom plate 32 is greater than the sum of the lengths of the hot-pressing structure and the transferring structure 4. The first transverse moving structure 33 is adapted to the length of the transverse bottom plate 32. In this way, the transverse bottom plate 32 can move transversely under the action of the first transverse moving structure 33, so that the forming bottom plate 34 and the transferring structure 4 can move to the forming position. For the forming base frame 3, after the first forming die 21 and the second forming die 22 move to the slurry pool 1, the paper-plastic slurry adheres to the inner wall of the forming cavity to form a slurry layer, the forming bottom plate 34 first moves to the position below the first forming die 21 and the second forming die 22, the air bag 31 on the upper side of the forming bottom plate 34 is inserted into the inner side of the first forming die 21 and the second forming die 22, and is preliminarily inflated, then the first forming die 21 or the second forming die 22 is controlled to open, the transferring structure 4 is controlled to approach the slurry layer, the transferring cavity 41 is attached to the remaining second forming die 22 or first forming die 21, then the second forming die 22 or first forming die 21 is separated from the slurry layer, so that the separation between the first forming die 21, the second forming die 22 and the slurry layer is completed. At this time, the preliminarily formed slurry layer is supported by the air bag 31 inside and the transferring cavity 41 of the transferring structure 4 outside. Under the action of the first transverse moving structure 33, the forming bottom plate 34 is moved to the position of the hot-pressing die 5, then the first hot-pressing die 51 or the second hot-pressing die 52 is first integrated with the transferring cavity 41, then the transferring cavity 41 of the transferring structure 4 is moved to approach the preliminarily formed slurry layer. At this time, the preliminarily formed slurry layer is surrounded by the first hot-pressing die 51 and the second hot-pressing die 52, so as to be hot-pressed. The preliminarily formed slurry layer is moved from between the first forming die 21 and the second forming die 22 to between the first hot-pressing die 51 and the second hot-pressing die 52. During the process, the preliminarily formed slurry layer is positioned inside by the air bag 31, and at least one of the first forming die 21 or the second forming die 22, the transferring cavity 41, the first hot-pressing die 51 or the second hot-pressing die 52 is used for side positioning.

Under the action of the second longitudinal movement structure 44, the transfer side plate 45 provided with the transfer cavity 41 can move towards or away from the forming bottom frame 3, at this time, the overall length of the second lateral movement structure 42 is the same as that of the first lateral movement structure 33, so that the transfer side plate 45 can also move at the positions of the forming mold 2 and the hot-pressing mold 5, thereby forming a support for the side edge of the preliminarily formed slurry layer at different positions.
[0045] At this time, the hot-pressing mold 5 is arranged in a spaced manner with the forming mold 2, and the transfer structure 4 is located between the hot-pressing mold 5 and the forming mold 2. The transfer structure 4 moves to the position of the forming mold 2 under the action of the first lateral movement structure 33 and moves to the position of the hot-pressing mold 5 under the action of the second lateral movement structure 42.
[0046] At the same time, the forming bottom plate 34 is located between the hot-pressing mold 5 and the forming mold 2, and the forming bottom plate 34 moves to the position of the forming mold 2 under the action of the first lateral movement structure 33 and moves to the position of the hot-pressing mold 5 under the action of the lower guide rail slider.
[0047] After hot-pressing forming, the paper-plastic bottle at the position of the hot-pressing mold 5 needs to be taken out, so in the embodiment, the paper-plastic bottle forming machine further includes a taking structure 6, which includes a lateral taking movement structure 61, a vertical taking movement structure 62, and a moving plate 63. The moving plate 63 moves laterally and vertically under the action of the lateral taking movement structure 61 and the vertical taking movement structure 62. The moving plate 63 is fixed with a rotating mechanism 64 at the side edge, the rotating shaft of the rotating mechanism 64 is connected with a rotating rod 65, and a plurality of limiting rods 66 are arranged on the rotating rod 65.
