[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-8 This utility model provides a technical solution for a rapid detection device for the moisture content of fillers, including a detection box 1. The opening of the detection box 1 is hinged with a box door 2. The top of the detection box 1 is provided with a cylinder 4. The bottom output end of the cylinder 4 passes through the interior of the detection box 1 and is connected to a sealing cover 5. The bottom of the detection box 1 is provided with a placement rack 3 that cooperates with the detection box 1. The placement rack 3 is provided with a material tray 9. The bottom of the sealing cover 5 is provided with a groove 11. The sealing cover 5 is provided with an inner cavity 12 located at the top of the groove 11. The inner cavity 12 is provided with an auxiliary drying mechanism. The bottom of the inner cavity 12 and the groove 11 are provided with an inlet and outlet that cooperate with the auxiliary drying mechanism. The top of the groove 11 is provided with a scraping component that cooperates with the inlet and outlet. Moisture-absorbing components are provided on both sides of the inner wall of the groove 11.
[0032] See Figure 4 The placement rack 3 includes a material rack 6 and a sealing plate 7. The material rack 6 and the sealing plate 7 are snapped together and fixed. Guide grooves 8 are provided on both inner walls of the material rack 6. Guide plates 10 that cooperate with the guide grooves 8 are provided on both sides of the material tray 9. Through the design of the placement rack 3, when placing the material tray 9 into the placement rack 3, the sealing plate 7 can be removed from the material rack 6 to facilitate the placement of the material tray 9 into the material rack 6. Then the sealing plate 7 is sealed again, which not only provides a placement space for the material tray 9, but also provides a closed base.
[0033] SeeFigure 2 , Figure 6 and Figure 7 The auxiliary drying mechanism includes a lead screw 13 rotatably connected to the top of the inner cavity 12. The end of the lead screw 13 is connected to a motor 14 located outside the sealing cover 5. A nut moving seat 15 is threaded onto the lead screw 13 and slidably connected to the interior of the inner cavity 12. An inclined seat 16 is fixed to the bottom of the nut moving seat 15. The auxiliary drying mechanism also includes vertical grooves vertically formed on both sides of the interior of the inner cavity 12. A slider 17 is slidably connected inside the vertical groove. A spring 18 is provided between the bottom of the slider 17 and the inner bottom of the vertical groove. A spring is fixed between the two sliders 17. An extrusion plate 19 is provided, and both sides of the top of the extrusion plate 19 are provided with inclined surfaces that cooperate with the inclined seat 16. The bottom of the extrusion plate 19 is flush with the bottom opening of the inlet and outlet. Through the design of the auxiliary drying mechanism, during heating, the motor 14 drives the lead screw 13 to rotate. The rotation of the lead screw 13 drives the nut moving seat 15 and the inclined seat 16 to move. While the inclined seat 16 moves, it will squeeze several extrusion plates 19 in sequence through the inclined surfaces. The extrusion plates 19 will descend vertically under the pressure, thereby driving the bottom end to insert into the material tray 9 to squeeze the filler. At the same time, the extrusion will cut the filler into segments, help the filler to dissipate heat and dehumidify, and speed up the dehumidification process.
[0034] See Figure 2 The nut moving seat 15 is provided with limiting blocks on both sides, and the inner walls of both sides of the inner cavity 12 are provided with limiting grooves that cooperate with the limiting blocks. Through the design of the limiting blocks and limiting grooves, the nut moving seat 15 can be rotated and limited, while the stability of the movement of the nut moving seat 15 can be improved.
[0035] See Figure 2 , Figure 7 and Figure 8 The scraping assembly includes sliding grooves 23 formed on the inner walls of both sides of the groove 11. A scraping plate 20 is slidably connected between the two sliding grooves 23. A lead screw 21 is rotatably connected inside the sliding grooves 23. The end of the scraping plate 20 is sleeved on the lead screw 21. The end of the lead screw 21 is connected to the output end of the motor 22. Through the design of the scraping assembly, the inclined seat 16 moves to the end of the inner cavity 12. At this time, several extrusion plates 19 also rise back into the inner cavity 12. At this time, the bottom end of the extrusion plate 19 is located at the bottom of the inlet and outlet. Subsequently, the motor 22 starts the lead screw 21 to rotate. The rotation of the lead screw 21 will drive the scraping plate 20 to move linearly. The scraping plate 20 will scrape the bottom of several extrusion plates 19 located at the bottom of the inlet and outlet to avoid the loss and waste of filler.
[0036] See Figure 7The moisture absorption assembly includes a plurality of air inlets 24 formed on the inner wall of the groove 11. The ends of the air inlets 24 are connected to the air supply pipes set on the detection box 1 via flexible hoses. The ends of the air supply pipes are connected to the fans set on the outside of the detection box 1. Through the design of the moisture absorption assembly, the moisture generated during the heating of the material tray 9 by the heating tube will be transported by the air inlets 24, flexible hoses, air supply pipes and fans.
[0037] The inner wall of the material rack 6 is equipped with a heating tube (existing structure, not shown in the figure), and the material rack 6 is equipped with a temperature sensor (existing structure, not shown in the figure). Both the heating tube and the temperature sensor are connected to the electrical control box (existing structure, not shown in the figure) located outside the detection box 1. Through the design of the heating tube and the temperature sensor, the material tray 9 and the filling material inside can be heated to remove the moisture from the filling material.
[0038] In use, the filler to be tested is placed in the material tray 9 and weighed. Then, the sealing plate 7 is removed from the material rack 6, the material tray 9 is placed into the material rack 6, and then the sealing plate 7 is sealed again. This provides a place for the material tray 9 and also provides a closed base. Then, the sealing cover 5 is pushed down by the cylinder 4. The sealing cover 5 descends and seals with the placement rack 3, thus providing a closed space and preventing filler from splashing out during heating. Then, the material tray 9 and the filler inside are heated by the heating tube to remove moisture. During heating, the motor 14 drives the lead screw 13 to rotate. The rotation of the lead screw 13 drives the nut moving seat 15 and the inclined seat 16 to move. As the inclined seat 16 moves, it squeezes several extrusion plates in sequence through the inclined plane. The pressure plate 19 and the extrusion plate 19 are squeezed and will descend vertically, thereby driving the bottom end to insert into the material tray 9 to squeeze the packing. During the squeezing, the packing is cut into segments, which helps the packing dissipate heat and dehumidify, and speeds up the dehumidification process. After dehumidification is completed, the inclined seat 16 moves to the end of the inner cavity 12. At this time, several extrusion plates 19 also rise back into the inner cavity 12. At this time, the bottom end of the extrusion plate 19 is located at the bottom of the inlet and outlet. Then, the motor 22 starts the screw 21 to rotate. The rotation of the screw 21 will drive the scraper 20 to move linearly. The scraper 20 will scrape the bottom of several extrusion plates 19 located at the bottom of the inlet and outlet to avoid the loss and waste of packing. Then, wait for the packing to cool down. After cooling is completed, weighing is performed to measure the moisture content of the packing.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
