The several fixed rods slide through the two sliders.

[0008] Furthermore, each of the two sliders is fixedly connected to a connecting rod one at its bottom, and each of the two connecting rods one has a hollow rod slidably connected to its outer wall, and each of the two hollow rods has a connecting rod two fixedly connected to its top.

[0009] Furthermore, a fixing plate is fixedly connected to each of the two connecting rods two on the side that is close to each other, and two telescopic rods are fixedly connected to each of the two fixing plates two on the side that is close to each other. A push plate is fixedly connected to each of the several telescopic rods on the side that is close to each other.

[0010] Furthermore, spring 1 is sleeved on the outer wall of several telescopic rods, and the side of several spring 1 that is far apart from each other is fixedly connected to fixed plate 2. The side of several spring 1 that is far apart from each other is fixedly connected to push plate.

The bottom of each of the two second springs is fixedly connected to the two handles, and the top of each of the two second springs is fixedly connected to the two hollow rods.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up a centering mechanism, the items to be supplemented are placed on the conveyor belt, and the motor is started. When the motor rotates, shaft one also rotates. When shaft one rotates, the pulley also rotates. When the pulley rotates, it drives the pulley on shaft two to rotate via a belt. When shaft two rotates, fixed plate two rotates, and the conveyor belt also rotates. As the conveyor belt rotates, it carries the items to be supplemented. As the items move, they gradually move between the push plates. As shaft one rotates, the gears on it also move. When the gears on shaft one rotate, the gears on the bidirectional reciprocating screw also rotate, and the bidirectional reciprocating screw also rotates. When the bidirectional reciprocating screw rotates, the sliders on it slide closer to each other. Due to the restriction of fixed rod one, the sliders do not move with the bidirectional reciprocating screw. The reciprocating screw rotates and slides. When the slider slides, it carries the first connecting rod along with it. When the hollow rod slides, it moves along with the second connecting rod. When the second connecting rod moves, it carries the second fixed plate along with it. When the second fixed plate moves, it carries the telescopic rod along with it. When the telescopic rod moves, it carries the push plate along with it. When the push plates move closer together, they push the item to the center of the conveyor belt. Because the movement of the push plates is always consistent, the item is always in a certain position. This achieves the effect of centering the item, which ensures that the label is accurately affixed to the predetermined position of the product, improving the accuracy of the supplementary coding. The centered item ensures the integrity and standardization of the laser coding, so that the product's coding information is clear and accurate.

[0017] 2. By setting up an adjustment mechanism, when changing to items of different sizes, the size of the transmission rod can be adjusted to adapt to the size of the new item. By pulling the handle, the limiting rod is pulled out of the slide and the limiting groove. When the limiting rod is pulled, the second spring will be under tension. After the limiting rod is pulled out, the hollow rod is pulled outward or pushed inward to adapt to the size of the item. Then, the handle is released. When the handle is released, the second spring will pull the handle up. When the handle is pulled up, the limiting rod will also move accordingly, and then the limiting rod will insert from the slide into the corresponding limiting groove. This achieves the adjustment effect, allowing the equipment to adapt to items of different sizes, greatly improving the scope of use of the equipment, avoiding frequent equipment changes, and effectively reducing the company's operating costs.

[0031] A specific application of this embodiment is as follows: In use, the device is first placed in the appropriate position, then the item to be supplemented is placed on the conveyor belt 2119. The motor 2116 is then started. When the motor 2116 rotates, the first rotating shaft 2113 also rotates. When the first rotating shaft 2113 rotates, the pulley 2120 also rotates. When the pulley 2120 rotates, it drives the pulley 2120 on the second rotating shaft 2117 to rotate via the belt 2121. When the second rotating shaft 2117 rotates, the second fixing plate 218 rotates accordingly, and the conveyor belt 2119 also rotates. When the conveyor belt 2119 rotates, it carries the item to be supplemented, and as the item moves, it gradually moves to the push plate 211. Between 0 and 2113, as the rotating shaft 2113 rotates, the gear 2114 on it also moves. When the gear 2114 on the rotating shaft 2113 rotates, the gear 2114 on the bidirectional reciprocating screw 212 also rotates, and the bidirectional reciprocating screw 212 also rotates. When the bidirectional reciprocating screw 212 rotates, the sliders 213 on it slide closer to each other. Due to the restriction of the fixed rod 214, the sliders 213 do not rotate with the rotation of the bidirectional reciprocating screw 212, but only slide. When the sliders 213 slide, they will also slide with the connecting rod 215. When the hollow rod 216 slides, it will also move with the connecting rod 217. The device will also move accordingly. When connecting rod 217 moves, it will move fixing plate 218. When fixing plate 218 moves, it will move telescopic rod 219. When telescopic rod 219 moves, it will move push plate 2110. When push plates 2110 move closer to each other, they will push the item to the middle of conveyor belt 2119. Because the movement of push plates 2110 remains consistent, the item's position will also remain consistent. When the item moves to below the code supplementer 101, the item will be code supplemented. The code supplementer 101 is a DS-6912UD, which looks like a metal cuboid box. The front panel has indicator lights and buttons, and the rear panel has a power interface and video input / output interface. Audio interfaces, etc., are used for decoding and processing video and audio signals to achieve functions such as high-definition video and voice intercom. This achieves the effect of centering the object. When changing to objects of different sizes, the size of the transmission rod can be adjusted to adapt to the size of the new object. By pulling the handle 314, the limiting rod 313 is pulled out from the slide groove 312 and the limiting slot 311. When the limiting rod 313 is pulled, the second spring 315 will be under tension. After the limiting rod 313 is pulled out, the hollow rod 216 will be pulled outward or pushed inward to adapt to the size of the object. Then, the handle 314 is released. When the handle 314 is released, the second spring 315 will pull the handle 314 up. When the handle 314 is pulled up, the limiting rod 313 will also move accordingly.The limiting rod 313 will then insert from the slide groove 312 into the corresponding limiting groove 311, thereby achieving the adjustment effect.
