DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Please refer to Figures 2-5 A freeze-dried tablet production device, comprising a filling net belt 1, a filling device 2, a liquid nitrogen spraying tunnel 3, a tunnel net belt 4, a freeze dryer 6, a dispensing robot 13, a discharging net belt 14, a packaging assembly, a discharging assembly and a tray 20; the right end of the filling net belt 1 is connected to the tunnel net belt 4, and the filling device 2 is arranged on the filling net belt 1; the tunnel net belt 4 is provided with the liquid nitrogen spraying tunnel 3. The right end of the tunnel net belt 4 is connected to the freeze dryer 6, and the feeding trolley 5 is arranged between the tunnel net belt 4 and the freeze dryer 6. The freeze dryer 6 is connected to the discharging net belt 14, and the dispensing robot 13 is arranged at the right end of the discharging net belt 14; the packaging assembly is arranged at the rear side of the discharging net belt 14, and the discharging assembly is arranged at the front side of the discharging net belt 14.

[0027] Specifically, the tray 20 is provided with bubble eyes 21 arranged in an array, and the distance between adjacent two bubble eyes 21 is 1mm to 2mm.

[0028] The freeze-dried tablet production device provided by the utility model can fill liquid medicine in the tray 20, freeze-dry the liquid medicine, form freeze-dried tablets in the bubble eyes of the tray 20, and then put the freeze-dried tablets into the bubble eyes 21 of the bottom film. Since the appearance of the finished product medicine plate does not need to be considered in the freeze-drying process, the distance between the bubble eyes 21 on the tray 20 can be controlled to be 1mm to 2mm, so that the bubble eyes present a close arrangement layout effect, thereby improving the yield of each batch of the freeze dryer and the overall production capacity.

[0029] In addition, the size and spacing of the bubble eyes 21 on the tray 20 can be designed according to the required tablet pattern and the tray can be replaced; the outer dimensions of the tray 20 can be designed according to the size of the plate layer of the freeze dryer.

[0030] Specifically, the packaging assembly includes a forming station 8, a side hole station 9, a hot air station 10, a easy-to-tear line station 11 and a cutting plate station 12; the forming station 8, the side hole station 9, the hot air station 10, the easy-to-tear line station 11 and the cutting plate station 12 are arranged in sequence at the rear side of the discharging mesh belt 14.

[0031] Specifically, the discharging assembly includes a tray transfer mesh belt 16 and a tray transfer robot 15; the tray transfer mesh belt 16 and the tray transfer robot 15 are arranged at the front side of the discharging mesh belt 14. One end of the tray transfer mesh belt 16 is connected to the discharging mesh belt 14, and the other end is connected to the cleaning tunnel 17.

[0032] Specifically, one end of the filling mesh belt 1 away from the tunnel mesh belt 4 is connected to a tray feeding mesh belt 19, and the tray feeding mesh belt 19 is provided with a tray feeding robot 18 at the side.

[0033] Specifically, the tray is placed on the filling mesh belt 1 by the tray feeding robot 18, and then runs to the filling device 2 below for filling. After filling, it enters the tunnel mesh belt 4, and then passes through the liquid nitrogen spraying tunnel 3. Then the tray is sent to the freeze dryer 6 by the feeding car 5. After freeze drying, the freeze-dried tray is sent to the discharging mesh belt 14 by the discharging car 7. The freeze-dried tablet is sent to the forming station 8 by the dispensing robot 13, so that the freeze-dried tablet passes through the side hole station 9, the hot air station 10, the easy-to-tear line station 11 and the cutting plate station 12 in sequence to be packaged and formed. The tray is taken by the tray transfer robot 15 to the tray transfer mesh belt 16, and then transported to the cleaning tunnel 17 by the tray transfer mesh belt 16, and then transported to the tray feeding mesh belt 19, waiting for the next batch.

[0034] The freeze-dried tablet production device can closely arrange the bubble eyes on the tray 20 by filling into the filling tray first, compared with the method of directly filling into the bottom film with bubble eyes, so that the yield of the freeze dryer is improved, and the overall production capacity is improved.
