[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 5 A grinding device for the production of dry suspension is disclosed, including a pair of supports 10. A roller 20 is rotatably connected between the two supports 10. A plurality of grinding balls are placed in the roller 20. A first motor 30 fixedly connected to the side end shaft of the roller 20 is bolted to one side of one of the supports 10. An inlet and outlet 40 is opened at the bottom end of the roller 20. A sealing sliding cover 50 is slidably connected to the inlet and outlet 40. A card slot 60 is opened at the bottom end of the sealing sliding cover 50. A pair of insertion holes 100 are opened on one side of the sealing sliding cover 50. A feeding hopper 70 is fixedly installed between the two supports 10. An automatic opening and closing mechanism 80 is provided below one side of the other support 10. A connecting mechanism 90 is provided above one side of one of the supports 10.

[0021] Specifically, the feeding hopper 70 is located directly below the inlet and outlet 40. The length of the feeding hopper 70 is greater than the length of the inlet and outlet 40. A mesh long plate 110 is fixedly installed in the inlet and outlet 40.

[0022] In this implementation scheme, it is convenient for the feeding hopper 70 to collect the ground cefaclor dry suspension. The setting of the mesh long plate 110 can prevent the grinding balls inside the roller 20 from being discharged together with the cefaclor dry suspension, playing a blocking role.

[0023] Specifically, the connecting mechanism 90 includes an L-shaped plate 91. A pair of insertion rods 92 are welded to the inner wall of the side of the L-shaped plate 91 away from the roller 20. The insertion rods 92 are matched with the insertion holes 100. The L-shaped plate 91 is welded to the central end of the side wall of the roller 20.

[0024] In this embodiment, during feeding, the insertion hole 100 in the sealing sliding cover 50 is connected by an insertion rod 92, which will not interfere with the rotation of the roller 20, and thus will not interfere with the upward position of the feeding and discharging port 40.

[0025] Specifically, the automatic opening and closing mechanism 80 includes a bracket 81. The top surface of the bracket 81 is fixedly installed with a hydraulic cylinder 82. The top surface of the output end of the hydraulic cylinder 82 is fixedly installed with a lifting platform 83. The top surface of the lifting platform 83 is welded with a limiting stop 84. The inner walls on both sides of the lifting platform 83 are rotatably connected with a screw rod 85. One side of the lifting platform 83 is bolted with a second motor 86. The output end of the second motor 86 is fixedly connected to one end of the screw rod 85 by a shaft. The screw rod 85 is threadedly connected with a moving clamping block 87 that matches the clamping groove 60. The moving clamping block 87 is slidably connected to the front and rear of the top surface of the lifting platform 83. The bracket 81 is of an L-shaped structure. The bracket 81 is welded to one side of one of the supports 10. The lifting platform 83 is slidably connected to the protruding end of the bracket 81 up and down. The lifting platform 83 is slidably connected to the front and rear inner walls of one of the supports 10 up and down.

[0026] In this embodiment, the sealing sliding cover 50 can be automatically opened or closed without manual opening and closing, so that feeding and discharging can be achieved through one feeding and discharging port 40.

[0027] Specifically, a plurality of balls 120 are embedded in the side wall of the sealing sliding cover 50, and the balls 120 are attached to the surface of the limiting stop 84 close to the roller 20.

[0028] In this embodiment, the frictional resistance between the sealing sliding cover 50 and the limiting stop 84 can be reduced, and thus the stability of the roller 20 during rotation can be improved.

[0029] Working principle and usage process of the present utility model: Normally, the height of the lifting platform 83 is centered, and the limit stop 84 can limit the sealing sliding cover 50. When feeding, the hydraulic cylinder 82 is started to drive the lifting platform 83, the moving clamping block 87 and the limit stop 84 to move upward to the maximum height together. At this time, the limit stop 84 and the sealing sliding cover 50 are staggered from each other, which will not affect the sliding of the sealing sliding cover 50. At the same time, the moving clamping block 87 is clamped on the clamping groove 60. The second motor 86 is started to drive the screw rod 85 to rotate forward. At this time, the limit stop 84 will drive the sealing sliding cover 50 to move together. The jack 100 on the sealing sliding cover 50 will be connected to the plug rod 92 until the sealing sliding cover 50 is separated from the feeding and discharging port 40. At the same time, the sealing sliding cover 50 passes through the support 10. The hydraulic cylinder 82 is started to drive the lifting platform 83, the moving clamping block 87 and the limit stop 84 to move downward to the lowest position together. The moving clamping block 87 is separated from the clamping groove 60 and will not affect the subsequent sliding of the sealing sliding cover 50. The first motor 30 is started to drive the roller 20 to rotate. At this time, the feeding and discharging port 40 faces upward, and at the same time, the plug rod 92 moves circumferentially upward. At this time, the sealing sliding cover 50 also swings upward together with the plug rod 92 and is always aligned with the feeding and discharging port 40. The cefaclor for suspension to be ground is poured into the feeding and discharging port 40. After feeding is completed, the sealing sliding cover 50 is pushed so that the sealing sliding cover 50 is slidably connected to the feeding and discharging port 40 again. Finally, the hydraulic cylinder 82 is started to drive the lifting platform 83 to move upward to the centered position. At this time, the limit stop 84 fits the ball 120 on the sealing sliding cover 50, which can limit the sealing sliding cover 50. The first motor 30 is started to drive the roller 20 to rotate, and in cooperation with the grinding balls, the grinding of the cefaclor for suspension can be realized.
