[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] First embodiment

[0023] As Figures 1 to 3 shown, in this embodiment, the aluminum-plastic blister machine includes: a flat plastic PS conveying device 100, a bubble blowing device 200, a medicine granule adding device 300, a composite aluminum film FL conveying device 400, a heat sealing device 500, a blowing device 600, a batch marking device 10, a medicine plate cooling and flattening device 700, a product conveying device 800, and a product cutting device 900.

[0024] The bubble blowing device 200, the medicine granule adding device 300, the heat sealing device 500, the blowing device 600, the medicine plate cooling and flattening device 700, the product conveying device 800, and the product cutting device 900 are sequentially arranged on the blister machine frame 1000.

[0025] The flat plastic PS conveying device 100 and the product conveying device 800 sequentially convey the flat plastic PS to the bubble blowing device 200, the medicine granule adding device 300, the heat sealing device 500, the blowing device 600, the medicine plate cooling and flattening device 700, and the product cutting device 900. The bubble blowing device 200 blows medicine bubbles on the flat plastic PS. The medicine granule adding device 300 adds medicine granules into the medicine bubbles. The composite aluminum film FL conveying device 400 and the product conveying device 800 sequentially convey the composite aluminum film FL to the heat sealing device 500, the blowing device 600, the medicine plate cooling and flattening device 700, and the product cutting device 900. The heat sealing device 500 heat-seals the flat plastic PS with the added medicine granules and the composite aluminum film FL together to form a product strip PD. The blowing device 600 blows air to cool the heat-sealed product strip PD. The medicine plate cooling and flattening device 700 further cools and shapes the blown product strip PD. The product cutting device 900 cuts the cooled and shaped product strip PD.

[0026] In this embodiment, the batch marking device 10 is arranged between the blowing device 600 and the cooling and flattening device to perform batch marking on the product strip PD. The batch marking device 10 can be at any position after the product strip PD is prepared, or can also be arranged after the medicine plate cooling and flattening device 700.

[0027] In this embodiment, the flat plastic PS conveying device 100, the composite aluminum film FL conveying device 400, and the product conveying device 800 are conveyed by a conveying roller structure.

[0028] In this embodiment, the medicine plate cooling and flattening device 700 includes a cooler 710 and a pallet 720. The cooler 710 and the pallet 720 are respectively arranged on both sides of the product belt PD. Further, in this embodiment, the cooler 710 is arranged on one side of the composite aluminum film FL, that is, above; the pallet 720 is arranged on one side of the flat plastic PS, that is, above.

[0029] The cooler 710 has two cooling holes 711. The cooling holes 710 are parallel to the conveying direction of the product belt PD, and the cooling holes 711 are symmetrically arranged on the cooler 710. Cooling liquid or gas is introduced into the cooling holes 712 to cool the product belt PD. The cooling surface 712 of the cooler 710, that is, the surface in contact with the product belt PD, is arc-shaped, which can increase the shaping area and has the effect of pressing the product belt PD in the reverse direction (in the case of no shaping, the product belt PD bends towards the flat plastic PS).

[0030] The pallet 720 has an avoidance portion 712. In this embodiment, the avoidance portion 712 is strip-shaped. The width of the strip-shaped avoidance portion 712 can be the width of one row of medicine blisters or the width of multiple rows of medicine blisters. The surface of the pallet 720 in contact with the product belt is also arc-shaped, and the arcs of the cooler 710 and the pallet 720 match.

[0031] Under the action of the product conveying device 800, the product belt PD continuously passes through the medicine plate cooling and flattening device 700. The pallet 720 and the cooler 710 always press on both sides of the product belt. The medicine blisters pass through the strip-shaped avoidance portion 712 of the pallet 720. The pallet 720 presses on one side of the product belt PD, and the cooler 710 presses on the other side of the product belt PD to cool and shape the product belt PD.

[0032] Embodiment 2

[0033] As Figure 5 shown, in the aluminum-plastic blister machine of this embodiment, except that the structure of the medicine plate cooling and flattening device and the conveying method are different from those in Embodiment 1, other components are the same as those in Embodiment 1 and will not be repeated.

[0034] In this embodiment, the medicine plate cooling and flattening device 700 includes a cooler 710 and a pallet 720. The cooler 710 and the pallet 720 are respectively arranged on both sides of the product belt PD. Further, in this embodiment, the cooler 710 is arranged on one side of the composite aluminum film FL, that is, above; the pallet 720 is arranged on one side of the flat plastic PS, that is, above. The cooler 710 has two cooling holes 711. The cooling holes 710 are parallel to the conveying direction of the product belt PD, and the cooling holes 711 are symmetrically arranged on the cooler 710. Cooling liquid or gas is introduced into the cooling holes 712 to cool the product belt PD. These structures of the medicine plate cooling and flattening device are also the same as those in Embodiment 1.

[0035] In contrast, the cooling surface 712 of the cooler 710, i.e., the surface that fits against the product belt PD, is a flat surface. The upper surface of the pallet 720 is also a flat surface.

[0036] In this embodiment, the avoidance portion 721 of the pallet 720 is a plurality of avoidance holes; the positions and sizes of the avoidance holes match those of the medicine blisters. Moreover, the pallet 720 moves up and down, i.e., moves closer to and away from the product belt PD.

[0037] In this embodiment, the medicine plate cooling and flattening device is not continuous compared to the first embodiment, but is carried out area by area. The size of this area can be determined according to the size of the finally cut product or be an integer multiple of the final product.

[0038] Under the action of the product conveyor 800, the product belt PD conveys a medicine plate to the position of the medicine plate cooling and flattening device 700 and then stops conveying. The pallet 720 moves upward, i.e., moves closer to the product belt, the medicine blisters are inserted into the avoidance holes 721, and the pallet 720 fits against one side of the product belt and, together with the cooler 710, presses on both sides of the product belt PD.

[0039] After the medicine plate cooling and flattening device 700 completes the cooling and shaping process, the pallet 720 moves downward, i.e., moves away from the product belt, and the medicine blisters leave the avoidance holes 721. The product conveyor 800 starts, conveys the product belt PD to the right, and the next position of the product belt PD moves between the pallet 720 and the cooler 710. The cooling and shaping are carried out in a cycle.

[0040] It should be noted that in this text, relational terms such as front side, rear side, up, down, horizontal, etc. only refer to the drawings in this embodiment to facilitate the description of the relative positional relationship; from different perspectives, the relative positional relationship will change and does not play a complete restrictive role. The above specific embodiments only describe the main features and innovative points of this solution. Those skilled in the art should understand that this solution is not limited by the above embodiments. Without departing from the innovative points and the protection scope, this solution will have various changes, and these changes and improvements will all fall within the protection scope required by this solution. The protection scope required by this solution is defined by the appended claims and their equivalents.
