[0030] Referring to Figure 1 As shown, the present utility model provides a technical solution: An equipment for on-line monitoring of moisture in freeze-dried preparations, including a measuring instrument 1, a weighing pan 2 is installed on the surface of the measuring instrument 1, a machine frame 9 is fixedly installed on the surface of the measuring instrument 1, a machine cover 4 is rotatably installed at the port of the machine frame 9, a heat shield 6 is fixedly installed inside the machine cover 4, a heating coil 5 is fixedly installed inside the machine cover 4, a carrier 3 is placed on the surface of the weighing pan 2, a crushing structure 7 is provided on the surface of the carrier 3, and a scraping structure 8 is provided on the surface of the rotating shaft 704.
[0031] The following specifically describes the specific settings and functions of its crushing structure 7 and scraping structure 8.
[0032] Referring to Figures 1-3As shown in the figure, in this embodiment: The crushing structure 7 includes a rotating shaft 704 rotatably connected to the inside of the vehicle 3. A connecting bar 701 is fixedly connected to the side wall of the rotating shaft 704. A plurality of first comb bars 702 are uniformly and fixedly connected to the lower surface of the connecting bar 701. A limiting pin 706 is fixedly connected to the lower surface of the vehicle 3. A circular ring frame 705 is slidably connected to the surface of the limiting pin 706. A plurality of second comb bars 703 are uniformly and fixedly connected to the surface of the circular ring frame 705. The second comb bars 703 slidably penetrate through the vehicle 3. When the agglomerated freeze-dried preparation is pushed to the position of the second comb bars 703, during the interleaved movement between the first comb bars 702 and the second comb bars 703, the crushing work of the agglomerated freeze-dried preparation can be realized, thereby improving the evaporation efficiency of the freeze-dried preparation. Two mounting rods 709 are fixedly connected to the lower surface of the vehicle 3. A mounting ring 708 is fixedly connected to one end of the two mounting rods 709 close to each other. A motor 707 is fixedly installed inside the mounting ring 708. The output end of the motor 707 is fixedly connected to the rotating shaft 704. When the motor 707 is started, the motor 707 will drive the rotating shaft 704 to rotate, thereby realizing the driving rotation work of the connecting bar 701. The first comb bars 702 on the connecting bar 701 can realize the real-time leveling and stirring work of the freeze-dried preparation on the vehicle 3. A screw rod 710 is rotatably connected to the inside of the vehicle 3. The screw rod 710 is threadedly connected to the inside of the circular ring frame 705. Driving the screw rod 710 to twist can realize the driving work of the circular ring frame 705 at this time. A rotating block 711 is fixedly installed at the other end of the screw rod 710. Anti-slip lines are provided on the outside of the rotating block 711. Rotating the rotating block 711 will drive the screw rod 710 to twist.
[0033] Refer to Figures 1-2 and Figures 4-5As shown in the figure, specifically, the scraping structure 8 includes a limiting block 83 fixedly connected to the end side of the rotating shaft 704. A rotating pin 84 is rotatably connected inside the limiting block 83. A rotating frame 81 is fixedly connected to the side wall of the rotating pin 84. Two springs 88 are fixedly connected to the bottom side of the rotating frame 81. The other ends of the two springs 88 are fixedly connected to a scraping strip 82. The scraping strip 82 is slidably connected to the inner side of the rotating frame 81. The scraping strip 82 will be closely attached to the bottom wall of the carrier 3 under the elastic force of the spring 88. At this time, the motor 707 is started to rotate, and the scraping work of the freeze-dried preparation inside the carrier 3 can be realized, which facilitates the subsequent monitoring work of other freeze-dried preparations. Four jacks 89 are evenly arranged on the surface of the rotating pin 84. A fixing block 86 is fixedly connected to the surface of the limiting block 83. A bolt 85 is threadedly connected inside the fixing block 86. The size of the bolt 85 is adapted to the size of the jack 89. By rotating the bolt 85 inside the fixing block 86 and inserting the bolt 85 into the inner side of the corresponding jack 89, the fixing work of the rotated rotating frame 81 can be realized. A rotating plate 87 is rotatably connected to the upper end of the rotating frame 81. After the rotating frame 81 rotates to a position where it is in the same straight line as the connecting strip 701, by rotating the bolt 85 inside the fixing block 86 and inserting the bolt 85 into the inner side of the corresponding jack 89, the fixing work of the rotated rotating frame 81 can be realized.
[0034] Working principle: When it is necessary to detect the moisture content of the freeze-dried preparation inside the carrier 3, after placing the freeze-dried preparation inside the carrier 3, first rotate the rotating block 711. The rotating block 711 will drive the screw rod 710 to twist. At this time, the driving work of the circular ring frame 705 can be realized. The sliding of the circular ring frame 705 on the surface of the limit pin 706 plays a role in restricting the moving direction of the circular ring frame 705. The circular ring frame 705 will drive the second comb strip 703 to extend from the upper part of the carrier 3. After placing the carrier 3 on the weighing pan 2 and covering the machine cover 4, starting the heating coil 5 can realize the evaporation and drying work of the freeze-dried preparation inside the weighing pan 2, and then realize the real-time monitoring work of the moisture content of the freeze-dried preparation. During this process, start the motor 707. The motor 707 will drive the rotating shaft 704 to rotate, and then the driving rotation work of the connecting strip 701 can be realized. The first comb strip 702 on the connecting strip 701 can not only realize the real-time spreading and stirring work of the freeze-dried preparation on the carrier 3, but also when the agglomerated freeze-dried preparation is pushed to the position of the second comb strip 703, during the process of the staggered movement between the first comb strip 702 and the second comb strip 703, the crushing work of the agglomerated freeze-dried preparation can be realized, thereby improving the evaporation efficiency of the freeze-dried preparation. After the experiment is over, after taking out the carrier 3, the second comb strip 703 can be driven to a position horizontal with the bottom side of the carrier 3, which is convenient for subsequent personnel to scrape the freeze-dried preparation adhered to the inside of the carrier 3. By setting the crushing structure 7, the flexible crushing work of the agglomerated freeze-dried preparation inside the carrier 3 is facilitated, so that the evaporation work after crushing the agglomerated freeze-dried preparation is facilitated, shortening the time for real-time monitoring of the freeze-dried preparation to a certain extent and improving the monitoring efficiency of the moisture content in the freeze-dried preparation.
[0035] After the second comb strip 703 is retracted, rotate the rotating frame 81 inside the limit block 83. When the rotating frame 81 rotates to a position on the same straight line as the connecting strip 701, rotate the bolt 85 inside the fixing block 86 and insert the bolt 85 into the corresponding jack 89, and the fixing work of the rotated rotating frame 81 can be realized. At this time, the scraping strip 82 will be tightly attached to the bottom wall of the carrier 3 under the elastic force of the spring 88. At this time, start the motor 707 to rotate, and the scraping work of the freeze-dried preparation inside the carrier 3 can be realized, which is convenient for subsequent monitoring work of other freeze-dried preparations. When it is necessary to retract the rotating frame 81, the rotating frame 81 can be flipped to a position overlapping the connecting strip 701 for fixation, and then press the scraping strip 82 to retract it inside the rotating frame 81, and then rotate the rotating plate 87 to block the end side of the scraping strip 82. At this time, the retraction work of the rotating frame 81 can be realized, which is convenient for the subsequent normal closing of the machine cover 4. By setting the scraping structure 8, the flexible scraping work of the freeze-dried preparation adhered to the inside of the carrier 3 is facilitated, and the use performance of the freeze-dried preparation moisture monitoring device is further improved.
