[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] It should be noted that, in the description of this application, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on this application.

[0025] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0026] like Figure 1-Figure 2 As shown, the utility model provides a technical solution: a device for screening defective tablets, comprising a support platform 1 and a fixed platform 4, a screening structure 2, arranged at the top of the support platform 1, for screening defective tablets; an arranging structure 3, arranged at the bottom of the screening structure 2, for arranging the screened tablets; a crawler weighing structure 5, arranged at the top of the fixed platform 4, for classifying the defective tablets after screening and arranging;

[0027] The screening structure 2 includes a screening frame 201, a plurality of screening holes 205 are opened at the bottom end of the screening frame 201, and a fixed plate 202 is installed between the inner walls of the screening frame 201, a rotating motor 203 is installed at the center of the top of the fixed plate 202, a cam is installed at the output end of the rotating motor 203, and a cam 204 is installed on the outer wall of the cam. A support leg 206 is installed at the bottom end of the screening frame 201, and the support leg 206 is connected to the top of the support platform 1.

[0028] It should be clear that in the embodiments of the present application, Figure 2 As shown, the screening structure 2 is capable of performing preliminary screening of tablets by pouring the tablets into the screening frame 201. The vibration motor 203 on the fixed plate 202 in the screening frame 201 drives the cam and the cam 204 to rotate. In a specific scheme of the present application, the cam 204 is actually an adjustable eccentric block installed on the rotor shaft. The centrifugal force generated by the high-speed rotation of the shaft and the eccentric block is used to obtain an exciting force, thereby generating a vibration force on the screening frame 201, and screening the tablets in the screening frame 201. This vibration motor 203 is a prior art and will not be described in detail.

[0029] like Figure 2 As shown, in order to facilitate the arrangement, weighing and distinguishing of defective tablets after screening, a mounting plate 301 is set between the support legs 206. By opening a groove 306 at the top center of the mounting plate 301, the screened tablets can fall into the groove 306. It should be clear that in the embodiment of the present application, the rotating block 302 is rotated by an external motor. The rotating rotating block 302 can slide the tablets in the groove 306 to the guide block 303. Since there is a guide block 303 and an arc block 305 between them, the tablets in the groove 306 can be moved to the guide block 303. The arrangement rod 304 is provided so that crowded tablets can be discharged into the groove 306 and rearranged. Since the guide block 303 and the arc block 305 are both arc-shaped, the tablets can enter the arrangement bucket 307 along the conveying path formed by the guide block 303, the arc block 305 and the groove 306, so that the tablets can be arranged. For ease of use, it should be clear that the guide block 303, the arc block 305 and the rotating block 302 are all detachable structures, which can be replaced according to different tablet requirements.

[0030] like Figure 3As shown, it should be clear that in order to be able to distinguish defective tablets after arrangement, a crawler weighing structure 5 is set on the fixed platform 4 on the left and right of the support platform 1. The crawler weighing structure 5 includes a support frame 501, and a conveyor belt 502 is rotatably set between the support frames 501. The outer walls of the support frames 501 are respectively installed with weight sensors 503 and fixed blocks 504. A rotating rod 505 is rotatably set at the top of the fixed block 504, and a discharge hopper 506 is installed on the outer side of both ends of the support frame 501. It should be noted that the conveyor belt 502 uses an external motor as a power source. When the tablets fall on the conveyor belt 502 one by one, in the embodiment of the present application, a weight sensor 503 is provided at the bottom of the conveyor belt 502, which can sense the weight of the moving tablets. The weight sensor 503 senses the weight of the tablets. When the tablets are damaged or broken, there will be inconsistent weight. The weight sensor 503 will control the external control system to control the rotating rod 505 to rotate. The rotating rod 505 can collect the identified defective tablets through the discharge hopper 506.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
