The first driving pulley 32 and the first driven pulley 33 are respectively rotatably installed at both ends of the frame body 31. The first belt 34 is wound around the first driving pulley 32 and the first driven pulley 33 at the same time; a supporting plate 36 is fixedly installed at the position directly below the advancing section of the first belt 34 on the frame body 31.

In this embodiment, the reflector 6 is taken as an example for description. The frame 31 is fixedly installed with a mounting rod 311, and the mounting rod 311 extends in the horizontal direction; a connecting block 312 is installed on the mounting rod 311, the connecting block 312 is arranged vertically, through holes 313 are opened at both ends of the connecting block 312, and deformation slits 314 communicating with the through holes 313 are opened at positions corresponding to the through holes 313 at both ends of the connecting block 312; the mounting rod 311 passes through one of the through holes 313 at the bottom, and a connecting rod 315 passes through the connecting block 312 corresponding to one of the through holes 313 at the top, and the reflector 6 is fixedly installed on the connecting rod 315; locking bolts 316 are threadedly installed at positions corresponding to the deformation slits 314 of the connecting block 312; thus, when the connecting block 312 is detached from the mounting rod 311, the disassembly of the reflector 6 can be completed.

[0041] Referring to Figure 2 and Figure 3 , when two rows of products are conveyed on two conveyors 3 respectively, then a light sensor 5 and a reflector 6 are installed on each conveyor 3; when the products are conveyed between the two conveyors 3, then the light sensor 5 and the reflector 6 on one of the conveyors 3 are removed, and the light sensor 5 and the reflector 6 on the other conveyor 3 are respectively arranged on both sides in the conveying direction of the two conveyors 3 to achieve avoidance.

[0042] The implementation principle of a dual-channel weighing device in an embodiment of this application is as follows: when the size of the product is smaller than the width of a single conveyor 3, then the two-row conveying method can be used to convey on two conveyors 3 respectively, and the weighing of two rows of products can be completed; when the size of the product is larger than the width of a single conveyor 3, then the product can be conveyed from the position between the two conveyors 3, and the weighing is completed through the cooperation of two weighing sensors 4.
