The loading box 7 is a prior art. When the conveying chain 101 moves the hard sheet into the loading box 7, the loading box 7 can place the medicine in the blisters on the hard sheet to achieve automatic feeding. It also includes: a conveying plate 2, multiple groups of conveying plates 2 are arranged at equal intervals, and the avoidance grooves 201 on two adjacent conveying plates 2 just correspond to the positions of two adjacent blisters on the hard sheet one by one. Both ends of the conveying plate 2 are detachably connected to the conveying chain 101. An avoidance groove 201 for accommodating the blisters is opened on the conveying plate 2, and the groove width of the avoidance groove 201 matches the diameter of the blisters, so that the avoidance groove 201 can just accommodate the blisters. During use, when the conveying chain 101 conveys the hard sheet, the hard sheet is placed on the conveying plate 2, and at this time, the blisters on the hard sheet are located in the avoidance grooves 201. When the film sealing roller 5 presses and heat-seals the aluminum foil on the hard sheet, the blisters can be prevented from being stressed, that is, the blisters can be prevented from being pressed, so as to prevent the blisters from collapsing and deforming and avoid the medicine from being crushed, improving the product quality; a film sealing box 3 is fixedly arranged on the frame 1. In the advancing direction of the conveying chain 101, the film sealing box 3 is located behind the loading box 7, that is, after the loading box 7 places the tablets, they will then enter the film sealing box 3 for heat-sealing. Among them, a heating roller 4 and a film sealing roller 5 are respectively rotatably arranged in the film sealing box 3. The heating roller 4 can heat the aluminum foil to facilitate heat-sealing the aluminum foil on the hard sheet. The outer wall of the film sealing roller 5 abuts against the top end face of the conveying plate 2. And an aluminum foil roller 301 is rotatably arranged in the film sealing box 3, and two supporting wheels 105 are rotatably arranged in the film sealing box 3. The two supporting wheels 105 are respectively engaged with the conveying chain 101, and the two supporting wheels 105 are respectively located on both sides of the film sealing roller 5, which can support the conveying chain 101 to prevent the conveying chain 101 from bending here and affecting the heat-sealing effect. During use, the hard sheet enters the film sealing box 3 under the conveyance of the conveying chain 101, and the aluminum foil on the aluminum foil roller 301 moves from the heating roller 4 to the film sealing roller 5, and then the film sealing roller 5 can heat-seal the aluminum foil on the hard sheet.

[0025] During use, by arranging the conveying plate 2 on the conveying chain 101 and opening an avoidance groove 201 on the conveying plate 2, when the film sealing roller 5 presses the aluminum foil thermally on the hard sheet, the bubble nests can be prevented from being stressed, thereby preventing the bubble nests from collapsing and deforming and avoiding damage to the drugs. Moreover, supported by the conveying plate 2, the aluminum foil can be more tightly attached to the hard sheet, which helps to improve the product quality. By opening a first heating cavity 404 in the heating roller 4 and a second heating cavity 501 in the film sealing roller 5, the heat source can first enter the first heating cavity 404 to heat the heating roller 4, and then enter the second heating cavity 501 through the connecting pipe 403 to heat the film sealing roller 5. On the one hand, it can prevent a large temperature difference between the film sealing roller 5 and the aluminum foil from affecting the heat sealing effect. On the other hand, the residual temperature of the heat source can be reused to improve the utilization rate of the heat source.
