[0024] See also Figure 1-5 The utility model provides a technical solution for powder type medicine screening equipment which is convenient for replacing the vibrating screen:

[0025] A powder medicine screening device with convenient replacement of oscillating screens comprises an outer cylinder 1, a mounting cylinder 2 is rotatably provided inside the outer cylinder 1, a plurality of mounting ports are opened on the surface of the mounting cylinder 2, and a fixing frame 3 is fixedly connected to the inner wall of the mounting port, a screen 4 is detachably connected to the inner wall of the fixing frame 3, and a replacement port 5 is provided just above the surface of the outer cylinder 1. The mounting cylinder 2 rotates to drive the screen 4 at the bottom to the replacement port 5 for replacement. By providing a rotatable mounting cylinder 2, the screen 4 originally located at the bottom is moved to the top and can be replaced through the replacement port 5. At the same time, the screen 4 originally located at the top is moved to the bottom to continue screening work without stopping for replacement. At the same time, the replacement port 5 is provided at the top, which has a larger operating space for users to conveniently perform replacement work.

[0026] Both ends of the mounting tube 2 are fixedly connected with end covers 6, the outer side of the end covers 6 is fixedly connected with a slider 7, one end of the outer tube 1 is fixedly connected with a fixing plate 8, the inner side of the fixing plate 8 and the inner wall of the outer tube 1 are provided with sliding grooves, and the slider 7 is slidingly connected to the inner wall of the sliding groove, and the outer side of the fixing plate 8 is fixedly connected with a rotating motor 9, the output end of the rotating motor 9 passes through the inner wall of the fixing plate 8 and is fixedly connected to the corresponding end cover 6, and one of the end covers 6 is driven to rotate by the output end of the rotating motor 9, thereby driving the mounting tube 2 to rotate, and the slider 7 is provided to realize that the end cover 6 drives the mounting tube 2 to rotate.

[0027] A mounting hole is provided on one side of the outer cylinder 1, and a feed pipe 10 is fixedly connected to the inner wall of the mounting hole. One end of the feed pipe 10 extends to the interior of the mounting cylinder 2, and a avoidance opening is provided on the outer side of the end cover 6 away from the rotating motor 9, and the inner diameter of the avoidance opening is larger than the outer diameter of the feed pipe 10. The feed pipe 10 is provided for feeding, and the avoidance opening is provided to prevent the feed pipe 10 from affecting the rotation of the mounting cylinder 2.

[0028] There are two mounting ports and two screens 4, and the two screens 4 are arranged radially along the mounting cylinder 2. By setting two screens 4 and arranging them radially, the mounting cylinder 2 can be rotated 180 degrees, with one at the top and the other at the bottom, so that replacement is convenient.

[0029] A right-angled slide rod 11 is fixedly connected to the inner side of the fixed frame 3, a sliding groove is opened on the inner side of the end cover 6, and the slide rod 11 is slidably connected to the inner wall of the sliding groove, and a spring 12 is fixedly connected to the inner bottom wall of the sliding groove, and the other end of the spring 12 is fixedly connected to the surface of the slide rod 11.

[0030] A rotating shaft 13 is rotatably connected between the inner wall of the outer cylinder 1 and the fixed plate 8, an eccentric block 14 is fixedly connected to the surface of the rotating shaft 13, and a driving motor 15 is fixedly connected to the outer side of the fixed plate 8. The output end of the driving motor 15 passes through the inner side of the fixed plate 8 and is fixedly connected to one end of the rotating shaft 13. The position of the eccentric block 14 corresponds to the fixed frame 3. The rotating shaft 13 is driven to rotate by the output end of the driving motor 15, and then the eccentric block 14 is driven to rotate, so that the eccentric block 14 intermittently lifts the fixed frame 3 at the bottom. By setting a spring 12, the fixed frame 3 can be reset, and then the fixed frame 3 drives the screen 4 to vibrate up and down, so as to achieve screening of powdered medicines.

[0031] The inner wall of the replacement port 5 is rotatably connected to an opening and closing door 16 via a hinge, and the surfaces of the opening and closing door 16 are fixedly connected to a limit strip 17 and a handle 18, respectively. The lower surface of the outer cylinder 1 is fixedly connected to a supporting leg 19, and a discharge hole is also provided at the bottom of the outer cylinder 1 for discharging materials from the screening port, which is not shown in the figure.

[0032] Working principle: When the powder medicine screening device with convenient replacement of oscillating screen is used, the user first starts the driving motor 15 and uses the feeding pipe 10 to feed the material into the installation cylinder 2, and the material falls on the screen 4 at the bottom. The output end of the driving motor 15 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the eccentric block 14 to rotate. The eccentric block 14 intermittently lifts the fixed frame 3 at the bottom, and with the cooperation of the spring 12, the fixed frame 3 drives the screen 4 to vibrate up and down to achieve the screening of powder medicine. During the screening process, the material with smaller particle size falls from the screen 4 to the bottom of the outer cylinder 1 and is discharged from the discharge hole, while the material with larger particle size remains on the screen 4. After the screening is completed, the rotating motor 9 is started, and the output end of the rotating motor 9 drives one of the end covers 6 to rotate, and the end cover 6 drives the installation cylinder 2 to rotate, thereby causing the screen 4 at the bottom to rotate toward the top. At this time, the material with larger particle size on the screen 4 falls and falls from the replacement port 5 to the bottom of the outer cylinder 1 and is discharged from the discharge hole;

[0033] When the bottom screen 4 needs to be replaced, the rotating motor 9 is started, and the output end of the rotating motor 9 drives one of the end covers 6 to rotate, thereby driving the mounting cylinder 2 to rotate, so that the screen 4 originally located at the bottom moves to the top, and the opening and closing door 16 is opened to replace the screen 4 from the replacement port 5. At the same time, the screen 4 originally located at the top moves to the bottom to continue the screening work without stopping for replacement. The powder medicine screening equipment with convenient replacement of the oscillating screen solves the problem of the need to stop for replacement of the oscillating screen in the prior art to affect the work efficiency.
