[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0024] like Figures 1 to 4 As shown, a visual inspection and anomaly rejection device for the outer packaging of rice crackers includes a base 1, on which a first workbench 2 and a second workbench 3 are respectively mounted. The relative height of the first workbench 2 is higher than that of the second workbench 3. Several support legs 4 are bolted to the first workbench 2 and the second workbench 3. A belt mounting frame 5 is provided on the support legs 4. A conveyor belt 6 for conveying materials is provided on the belt mounting frame 5. A first rejection mechanism for rejecting stuck packages is provided at one end of the belt mounting frame 5. A second rejection mechanism is also provided at the center of the belt mounting frame 5. A belt quick-release mechanism is provided on the conveyor belt 6.

[0025] The conveyor belt 6 enables materials to pass through the inspection area quickly and continuously. The belt mounting bracket 5 facilitates the installation and debugging of the conveyor belt 6. The belt quick-release mechanism makes the replacement and maintenance of the conveyor belt 6 more convenient and faster. The outer bags can first pass through the first rejection mechanism to remove the glued outer bags, and then pass through the second rejection mechanism to check and reject the color mark, cut edge, production date, etc. of the outer bags, thereby improving the product yield and making the efficiency higher.

[0026] The first rejection mechanism is located at the feed end of the conveyor belt 6. The first rejection mechanism includes a first air blowing solenoid valve 7, a first mounting plate 8, and a photoelectric sensor 9. The first air blowing solenoid valve 7 passes through the belt mounting frame 5 and is fixed to the belt mounting frame 5 by bolts through the first mounting plate 8. The photoelectric sensor 9 has several units and is respectively set on the inner wall of both sides of the belt mounting frame 5.

[0027] The outer bag enters the conveyor belt 6 and is first detected by the photoelectric sensor 9. If the photoelectric sensor 9 detects that the bag is stuck together, the first air blowing solenoid valve 7 starts to work and blows air to remove the outer bag. The first mounting plate 8 provides corresponding support for the first air blowing solenoid valve 7.

[0028] The second rejection mechanism includes an operation box 10, a vision camera 11, a camera mounting plate 12, a light source mounting plate 13, an upper light source 14, a lower light source 15, a second air-blowing solenoid valve 16, and a second mounting plate 17. The operation box 10 is bolted to the top of the belt mounting frame 5. The vision camera 11 is bolted to the inner wall of the operation box 10 via the camera mounting plate 12. The upper light source 14 is bolted to the inner wall of the operation box 10 via the light source mounting plate 13. The lower light source 15 is located on the upper surface of the belt mounting frame 5. The second air-blowing solenoid valve 16 passes through the belt mounting frame 5 and is bolted to the belt mounting frame 5 via the second mounting plate 17.

[0029] The conveyor belt 6 is made of transparent material. The upper light source 14 and the lower light source 15 illuminate the conveyor belt 6 simultaneously, so that the color mark, cut edge, production date, etc. on the outer bag can be clearly recorded by the vision camera 11. The vision camera 11 is connected to the second air blowing solenoid valve 16. When an abnormality is detected, the rejection action is triggered. The second air blowing solenoid valve 16 can blow air to reject the abnormal outer bag.

[0030] The belt quick-release mechanism includes a drive cylinder 18, a cylinder mounting plate 19, a cylinder connector 20, a rotating arm 21, a rotating base 22, and a rotating wheel 23. The bottom of the drive cylinder 18 is bolted to the surface of the second workbench 3 via the cylinder mounting plate 19. The cylinder connector 20 is located on the piston rod of the drive cylinder 18. The rotating arm 21 is rotatably connected to the cylinder connector 20. The bottom of the rotating arm 21 is rotatably connected to the rotating base 22, and its top is rotatably connected to the rotating wheel 23. The bottom of the rotating base 22 is bolted to the upper surface of the second workbench 3, and the rotating wheel 23 is rotatably connected to the conveyor belt 6.

[0031] The cylinder mounting plate 19 and the rotating base 22 provide corresponding support for the drive cylinder 18 and the rotating arm 21, respectively. The drive cylinder 18 provides power and transmits the power to the cylinder connector 20. The cylinder connector 20 drives the rotating arm 21 to rotate. The rotating arm 21 can drive the rotating wheel 23 to move. When the equipment is working, the rotating wheel 23 presses the conveyor belt 6. When it is necessary to disassemble the conveyor belt 6, the rotating wheel 23 releases the conveyor belt 6.

[0032] The top of the belt mounting bracket 5 is equipped with a display screen 24; the display screen 24 allows the operator to clearly see whether there are any abnormalities in the outer bags on the conveyor belt 6.

[0033] Two guide rollers 25 are bolted to the bottom of the belt mounting bracket 5. A drive wheel 26 is rotatably connected to the two guide rollers 25. The drive wheel 26 is rotatably connected to the conveyor belt 6 and is rotated by the conveyor motor 27.

[0034] The conveyor motor 27 provides power, which is transmitted to the drive wheel 26. The drive wheel 26 can drive the conveyor belt 6 to rotate, and the outer bag can be transported. The guide roller 25 provides support for the installation of the drive wheel 26.

[0035] Working principle: When in use, the outer bag enters the feed end of the conveyor belt 6. The conveyor motor 27 provides power, which drives the transmission wheel 26 to drive the conveyor belt 6. The outer bag begins to be transported. The photoelectric sensor 9 detects the sticky outer bag. The first air blowing solenoid valve 7 blows air to remove the sticky outer bag. Since the upper light source 14 and the lower light source 15 illuminate the conveyor belt 6, the vision camera 11 can clearly see the details on the outer bag, achieving the purpose of detecting color marks, cut edges, production dates, etc. on the outer bag. The second air blowing solenoid valve 16 blows air to remove the unqualified outer bag. The qualified outer bag leaves the equipment through the conveyor belt 6.
