DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example

[0038] like Figure 1-2As shown, the utility model provides a device for rejecting edible salt packaging boxes without traceability codes, including: a first conveyor belt 1, a scanning mechanism 2, and a rejection mechanism 3. The scanning mechanism 2 is arranged on the edge of the first conveyor belt 1, and the rejection mechanism 3 is arranged at the conveying end of the first conveyor belt 1. The rejection mechanism 3 includes: a device slot 30, a conveying roller assembly 31, a first motor 32, a rotating shaft 33, and a stirring roller 35. The first motor 32 is connected to the conveying roller assembly 31 and drives the conveying roller assembly 31 to rotate. The rotating shaft 33 is arranged at an edge of the device slot 30, and one end of the rotating shaft 33 is connected to the second motor 34. A plurality of stirring rollers 35 are fixed on the rotating shaft 33 at intervals, wherein the second motor 34 is connected to the PLC control system, and the scanning mechanism 2 is connected to the PLC control system. The rotation of the rotating shaft 33 can move the material on the conveying roller assembly 31 to one side of the device slot 30. The scanning mechanism 2 scans the traceability code on the edible salt packaging box placed on the first conveyor belt 1. Preferably, the height of the scanning mechanism 2 is adjustable so as to adapt to edible salt packaging boxes of different heights. When the scanning mechanism 2 scans the traceability code on the edible salt packaging box and finds an error or no traceability code, it transmits a signal to the PLC control system. The PLC control system controls the moving roller 35 to move the edible salt packaging box moved to the side of the device slot 30 in the rejection mechanism 3, thereby completing the rejection of the edible salt packaging box without a traceability code or with a damaged traceability code.

[0039] It should be noted that after receiving the signal transmitted by the scanning mechanism 2, the PLC control system controls the second motor 34 to rotate according to the conveying speed of the first conveyor belt 1 and the rotation speed of the first motor 32, thereby driving the moving roller 35 to rotate and remove the edible salt packaging box.

[0040] In this embodiment, the device slot 30 includes: a device base plate 300, a first support plate 301, and a second support plate 303. The first support plate 301 is vertically arranged at one edge of the device base plate 300. A plurality of first connection holes 302 are arranged at intervals on the first support plate 301. The first support plate 301 is arranged along the conveying direction of the first conveyor belt 1. The second support plate 303 is oppositely arranged at the other edge of the device base plate 300. Second connection holes 304 corresponding to the first connection holes 302 are provided on the second support plate 303. A plurality of notches 305 are arranged at intervals on the second support plate 303. The second support plate 303 is provided with a third connection hole 306 along the conveying direction of the first conveyor bed. The axes of the first connection holes 302 and the second connection holes 304 are perpendicular to the axis of the third connection hole 306. The rotating shaft 33 is rotatably arranged in the third connection hole 306, and the driving roller 35 is restricted in the notch 305.

[0041] In this embodiment, the conveying roller assembly 31 includes: a conveying shaft 310, a rotating wheel 311, a first roller 312, and a transmission belt 313. One end of the conveying shaft 310 can be rotatably set in the second connecting hole 304, and the other end passes through the first connecting hole 302 and is fixed with the rotating wheel 311 at the end. The first rollers 312 are arranged at intervals on the conveying shaft 310, and the transmission belt 313 is connected to the outer surfaces of several transmission wheels, wherein the output shaft of the first motor 32 is fixed to the transmission wheel of one of the conveying shafts 310.

[0042] In this embodiment, the moving roller 35 includes: a fixed block 350, a connecting frame 351, and a second roller 352. The fixed block 350 is fixed on the outer surface of the rotating shaft 33, the connecting frame 351 is fixed on one side of the fixed block 350, and the connecting frame 351 can enter the device slot 30. The second rollers 352 are spaced and rotatably arranged in the connecting frame 351, wherein the axis of the second roller 352 is perpendicular to the axis of the first roller 312, and the highest point of the second roller 352 can be lower than the highest point of the first roller 312. When the second motor 34 is not working, the highest point of the second roller 352 is lower than the highest point of the first roller 312, and the edible salt packaging box can be normally transmitted from the first roller 312. When the second motor 34 rotates, it drives the paddle roller 35 to rotate, and the highest point of the second roller 352 is higher than the highest point of the first roller 312, so that the second roller 352 directly contacts the bottom surface of the edible salt packaging box, and the connection between the first roller 312 and the edible salt packaging box is disconnected. Since the paddle roller 35 is tilted, it is affected by the dead weight of the edible salt packaging box and can drive the second roller 352 to rotate, thereby removing the edible salt packaging box without traceability code or with damaged traceability code.

[0043] In this embodiment, a first carrier plate extends from the first support plate 301, and the first motor 32 is disposed on the first carrier plate. A second carrier plate extends from the second support plate 303, and the second motor 34 is disposed on the second carrier plate. The second conveyor belt 4 is disposed at the conveying end of the rejecting mechanism 3.
