Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Embodiment 1: Figure 1-4 As shown, the utility model provides a radiographic film drying device, comprising a box body 1, an inner wall of the box body 1 is provided with a drying device 2, and a lower inner wall of the box body 1 is provided with a sliding device 3;
[0021] The sliding device 3 includes a screw rod 31, and the inner walls on both sides of the screw rod 31 are rotatably connected to the inner walls on both sides of the box body 1 respectively. The inner walls on both sides of the box body 1 are rotatably connected to two driven rods 32 respectively. The outer surface of the screw rod 31 is sleeved with a slide plate 33. A motor 34 is provided at the lower part of one end of the box body 1. The output end of the motor 34 passes through one end of the box body 1 and is fixedly connected to one end of the screw rod 31. The outer surfaces of the two driven rods 32 are slidably connected to four rollers 35. The outer surfaces of the driven rods 32 are respectively fitted with the inner walls of the four rollers 35. Both ends of the slide plate 33 are rotatably connected to four rotating shafts 36 distributed in a rectangular array. One end of the rotating shaft 36 is connected to one end of the roller 35. The slide plate 33 is fixedly connected. When the slide plate 33 moves, it drives the multiple rotating shafts 36 to move and rotate. When the rotating shaft 36 rotates, it drives the inner wall of the roller 35 to slide on the outer surface of the driven rod 32. The top of the slide plate 33 is fixedly connected with a heating plate 37. The top of the heating plate 37 fits with the bottom of the placement frame 21. Three heat preservation lamps 4 are fixedly connected to the inner walls of both sides of the box body 1 at equal intervals. The outer surface of the heat preservation lamp 4 fits with one side of the placement frame 21. When the heating plate 37 moves, hot air will enter the interior of the placement frame 21 from the ventilation slots 24 opened in the multiple placement frames 21, and the X-ray film placed in the placement frame 21 is dried, and the outer surface of the X-ray film can be evenly heated.
[0022] The drying device 2 includes a plurality of placement frames 21, both ends of which are fixedly connected to support frames 22, and both side inner walls of the box body 1 are fixedly connected to support plates 23. The bottom ends of the plurality of support frames 22 in the same horizontal plane are slidably connected to the top ends of the support plates 23. A slider 26 is fixedly connected to the bottom end of the support frame 22. A slide groove 27 for cooperating with the slider 26 is provided at the top end of the support plate 23. The outer surface of the slider 26 fits the inner wall of the slide groove 27. The slider 26 and the slide groove 27 are both in a "T" shape. Ventilation grooves 24 are provided at both ends of the placement frame 21, and a placement groove 25 is provided at the top end of the placement frame 21. The outer surface of the slider 26 is aligned with the inner wall of the slide groove 27 provided on the support plate 23, and the slider 26 is slid into the inner wall of the slide groove 27. This can prevent the drying device from directly contacting the X-ray film and burning the X-ray film.
[0023] Working principle: First, the X-ray films to be dried are placed in the placement slots 25 provided in the multiple placement frames 21 in the drying device 2, and two support frames 22 are slid respectively, and the outer surface of the slider 26 is aligned with the inner wall of the slide slot 27 provided in the support plate 23, and the slider 26 is slid into the inner wall of the slide slot 27, so as to avoid the film drying device directly contacting the X-ray film and burning the X-ray film;
[0024] Multiple heat-keeping lamps 4 on both sides of the box body 1 can keep the heat inside the box body 1 warm. When it is necessary to dry the X-ray film, the motor 34 in the sliding device 3 is turned on, and the output end of the motor 34 rotates to drive the screw rod 31 to rotate, and the screw rod 31 rotates to drive the slide plate 33 to move. When the slide plate 33 moves, it drives multiple shafts 36 to move and rotate respectively. When the shaft 36 rotates, it drives the inner wall of the roller 35 to slide on the outer surface of the driven rod 32. When the slide plate 33 moves, it drives the heating plate 37 to move. When the heating plate 37 moves, hot air will enter the interior of the placement frame 21 from the ventilation slots 24 opened in the multiple placement frames 21, and the X-ray film placed in the placement frame 21 is dried, thereby achieving the purpose of uniform heating of the outer surface of the X-ray film.
