The stabilizing strip 501, the connecting plate 502 and the positioning rods 503 cooperate with each other to form the cleaning structure 5. The support spring pushes the brush on one side of the stabilizing strip 501 to make flexible contact with the conveyor belt 203. The conveyor belt 203 can self-clean in conjunction with the brush during the movement. In this embodiment, two stabilizing blocks are provided on one side of the gantry above the stabilizing body 1. A second electric motor 601 is installed on the outer side of one of the stabilizing blocks. A set of bolt mounting holes are opened at the corner of the stabilizing block. Matching bolts are installed between the second electric motor 601 and the bolt mounting holes. After the bolts are installed, the mounting position of the second electric motor 601 is stabilized. A rotating hole is opened in the middle of the stabilizing block. A threaded rod 602 with a rotating connection is inserted into the rotating hole. The rotation position of the threaded rod 602 and the rotating hole is adjusted according to actual needs by adding a lateral positioning structure so that the threaded rod 602 can be laterally positioned. The threaded rod 602 is... The double-threaded structure has two symmetrically distributed positioning plates 603 installed on the outer side of the threaded rod 602.

The two positioning plates 603 cooperate to position the center of the tablet.

[0019] Example 2, based on Example 1, such as Figures 1-6 As shown, the scanning detector 101 and the cylinder 4 are electrically connected in accordance with the prior art. According to actual needs, a control module is set between the scanning detector 101 and the cylinder 4. When the scanning detector 101 detects a defective tablet in the slot, it transmits a signal to the cylinder 4. The cylinder 4 works to push the defective tablet outward, thus completing the automatic separation of the defective tablet.

[0020] The working principle of this embodiment: Place the stabilizing body 1 in a suitable position on the tablet production line. Fix the scanning detector 101 to the inside of the gantry of the stabilizing body 1 with bolts. Install the drive roller 202. Fix one of the drive rollers 202 to the drive shaft of the first electric motor 201 with a wedge key. Install the funnel 302 and the drainage housing 303 on the positioning frame 102 with the positioning pin 304 so that the drainage housing 303 is in an elastic support state. Connect the drive roller 202 to the pulley and belt of the rotating shaft 301.

[0021] A defective tablet collection box needs to be placed below the opening slot of the drainage housing 303, and an independent defective tablet collection container needs to be placed outside the push block of the cylinder 4 push rod to receive the defective tablets pushed out by the cylinder 4. The tablets to be tested are poured into the funnel 302, the first electric motor 201 is started, the roller 202 is driven to move the conveyor belt 203, and the rotating shaft 301 vibrates the funnel 302 through the cam, so that the tablets fall evenly into the screening screen of the drainage shell 303. The screening screen separates obviously defective tablets by vibration. If the tablets are broken in half, the defective tablets pass through the screening screen and are collected through the opening groove, while qualified products fall into the conveyor belt 203 to continue to be transported. The conveyor belt 203 transports qualified products to the area below the scanning detector 101, which performs appearance inspection on the tablets, such as detecting missing corners and discoloration. When a defective piece is detected, the scanning detector 101 sends a signal to the cylinder 4 through the control module. The push rod of the cylinder 4 extends, and the push block pushes the defective piece out from the side of the conveyor belt 203 and into the defective piece collection container. The qualified products continue to move to the next process with the conveyor belt 203. The positioning plate 603 of the positioning mechanism 6 moves synchronously in the opposite direction to ensure that the tablets remain in the center position during the conveying process, so as to avoid deviation and affect the accuracy of detection. During equipment operation, the brush of cleaning structure 5 moves with the conveyor belt 203 to automatically clean surface dust and debris. After the daily production ends, the first electric motor 201 is started to reverse, causing the conveyor belt 203 to run in reverse, further cleaning residual debris with the help of the brush. The belt tension is checked weekly. If it is loose, the gap between the drive rollers 202 needs to be adjusted or the belt needs to be replaced. The push rod of cylinder 4 is lubricated monthly by applying molybdenum disulfide grease. The detection accuracy of scanning detector 101 is calibrated quarterly, and the recognition accuracy is verified using standard tablet samples.
