After the film 19 continuously moves left and leaves the drying section D, the bottom of the film 19 contacts the small end of the wedge-shaped baffle 30, and with the continuous left movement of the film 19, the bottom of the film 19 is touched by the wedge-shaped baffle 30 until the film 19 is deformed, so that the film 19 completely passes over the wedge-shaped baffle 30, and the film 19 passing over the wedge-shaped baffle 30 is restored to the U-shaped state again. At the moment, the fixing clamp 4 enables the clamping part to be opened due to the supporting effect of the two wedge-shaped stoppers 2 at the left side of the shell 8, the two ends of the film 19 are synchronously separated from the fixing clamp 4, one end back to the film outlet 9 is lapped on the side wall of the shell 8 at the corresponding side, one end facing the film outlet 9 is extended out from the film outlet 9, the film 19 is naturally changed into an L shape from the U shape, and a doctor can conveniently take out the film from the film outlet 9.

Finally, the first motor 1 reversely outputs after the sliding block 5 touches the second travel switch 13, so that the sliding block 5 starts to move rightwards, and even if the fixing clamp 4 and the film 19 generate a right movement trend due to mutual friction force, the right movement trend can be stopped due to the blocking of the large end of the wedge-shaped blocking platform 30, so that the film 19 is neatly stacked at the position close to the large end of the wedge-shaped blocking platform 30. And after the sliding block 5 continuously moves to the right to touch the first travel switch 18, the fixing clamp 4 is opened again, the second motor is started again to shift the next film 19 into the clamping part and then closed, the first motor 1 rotates reversely again to output, and the film 19 is clamped and the cleaning, drying and stacking operations are repeated. The plurality of films 19 in the U-shaped stacking area 32 can be automatically processed and then neatly stacked at the film outlet 9, one end of the processed films 19 extends out of the film outlet 9, and doctors can draw out the films 19 one by one according to the registration sequence and place the films on the film viewing lamp panel 10 for diagnosis.
