[0028] As shown in the attached Figure 1 , 2 , 3, 5, 6, the adjustment component of the present invention includes a first transmission column 22, a second transmission column 25 correspondingly penetrating through and slidably connected to the bracket 1, a connecting frame 9 fixedly installed at the tops of the two first transmission columns 22, a movable shaft 8 rotatably installed on the connecting frame 9, and a baffle 7 fixedly installed at the tops of the two second transmission columns 25; the first transmission column 22 is connected to the transmission component, the bottom end of the second transmission column 25 is located above the transmission component, and the two first transmission columns 22 synchronously descend to drive the second transmission column 25 to drive the baffle 7 to rise through the transmission component; the baffle 7 and the movable shaft 8 are arranged on the conveying component at intervals.

Due to the limitation of the limiting rod 20, the left and right swing of the first connecting rod 23 is prevented.

[0030] As shown in the appendix Figures 1-4 As shown in the figure, first support plates 5 are correspondingly installed on the two side frames of the bracket 1 between the identification component and the baffle 7. Through holes are provided on the first support plates 5, and sleeves 19 are arranged in the through holes with a gap. Positioning vertical plates 4 are fixedly installed at the inner ends of the sleeves 19, and the side faces of the two positioning vertical plates 4 correspond to each other and are perpendicular to the baffle 7; a push rod 29 is slidably arranged in the sleeve 19, and a compression spring 28 is fixedly installed between the inner end of the push rod 29 and the inner side wall of the sleeve 19; a transmission folding rod 6 is installed at the outer end of the push rod 29, and the other end of the transmission folding rod 6 is connected to the slider 18.

[0031] As shown in the appendix Figure 1 、 2 As shown in FIGS. 3 and 7, the rejection component of the present invention includes a second support plate 14 fixedly installed on one side frame of the bracket 1, a notch 15 provided on the other side frame, an electric telescopic rod 26 fixed in the mounting hole of the second support plate 14, and a push plate 27 installed at the end of the electric telescopic rod 26; the push plate 27 corresponds to the notch 15, and the length of the notch 15 is greater than the width of the packing box.

[0032] As shown in the appendix Figure 1 、 2 As shown in FIGS. 6, the rejection component of the present invention includes a portal frame 3 arranged on the outer sides of the two side frames of the bracket 1 and an identification camera 16 fixedly installed at the bottom of the upper cross beam of the portal frame 3, and the identification camera 16 corresponds to the top surface of the conveying component; both the identification camera 16 and the electric telescopic rod 26 are connected to the controller through signal lines.

[0033] As shown in the appendix Figure 1 、 2 As shown in FIGS. 3, the conveying component of the present invention includes roller shafts 2 rotatably installed between the two side frames of the bracket 1 at uniform intervals, driven sprockets 10 installed at one end of the roller shafts 2, a driving motor 13 fixedly installed at the bottom of the bracket 1, a driving sprocket 12 installed on the transmission shaft of the motor 13 and corresponding to the driven sprockets 10, and a chain 11 arranged on the driving sprocket 12 and the driven sprockets 10; the driven sprockets 10 are located outside the side frames of the bracket 1.

[0034] During the movement of the slider 18, the push rod 29 is driven to move through the transmission folding rod 6. Under the action of the compression spring 28, the sleeve 19 is driven to move, driving the positioning vertical plate 4 to move, so that the two positioning vertical plates 4 approach each other. Through the mutual approach of the two positioning vertical plates 4, the automatic centering of the packing box is realized.

[0035] During operation, the motor 13, the second sprocket 12, and the chain 11 are used to drive the rotation of each driven sprocket 10, which drives the rotation of the roller shaft 2. The rotation of the roller shaft 2 drives the movement of the packaging box. The switch of the identification camera 16 is turned on to prepare for barcode identification work. When the packaging box is transported to the movable shaft 8, the movable shaft 8 descends under the gravity of the packaging box. Through the restriction of the limiting rod 20 on the first connecting rod 23, the first connecting rod 23 moves up and down. The other end of the first connecting rod 23 moves upward and contacts the bottom end of the second transmission column 25, driving the second transmission column 25 to rise and driving the baffle 7 to rise. Under the conveying action of the roller shaft 2, when the packaging box is blocked by the baffle 7, the position of the packaging box is straightened. When the first connecting rod 23 moves, the slider 18 is driven to move along the guide rail 17 through the universal ball head 30 and the second connecting rod 31. During the movement of the slider 18, the push rod 29 is driven to move through the transmission folding rod 6. Under the action of the compression spring 28, the driving sleeve 19 moves forward and drives the positioning vertical plate 4 to move forward, so that the two positioning vertical plates 4 approach each other and clamp the packaging box in the middle, realizing the automatic centering of the packaging box, facilitating barcode identification work and subsequent sorting work. When the identification camera 16 identifies a packaging box with a missing barcode, the controller controls the electric telescopic rod 26 to push the push plate 27 to push the packaging box out of the bracket 1 through the notch 15, realizing the removal of the packaging box with a missing barcode.

[0036] Embodiment 2:

[0037] This embodiment is a further improvement based on Embodiment 1. An electromagnet is arranged in the sleeve 19, and the switch of the electromagnet is electrically connected to the controller. The compression spring 28 is a stainless steel spring, and the compression spring 28 will not be affected during the operation of the electromagnet. The electromagnet is installed on the inner side wall of the sleeve 19, and the center of the electromagnet is on the same straight line as the center of the sleeve 19.

[0038] During the detection process, the identification camera 16 takes pictures of the packaging box on the roller shaft 2. When the packaging box is in a nearly centered state, the identification camera 16 transmits the taken picture to the controller in the form of a signal. The controller disconnects the switch of the electromagnet, so that the positioning plate 4 pushes the packaging box closer to the center, facilitating the adjustment of the position of the packaging box. When the packaging box is on one side of the roller 2, the identification camera 16 transmits the signal to the controller. The controller turns on the switch of the electromagnet, and the electromagnet works to adsorb the push rod 29, so that the sleeve 19 moves along the outer surface of the push rod 29, compressing the compression spring 28. During this process, the positioning plate 4 moves closer to the first support plate 5, and then the two positioning plates 4 move away from each other, so that the packaging box is not blocked by the positioning plate 4 during the conveying process. Furthermore, during the movement of the positioning plate 4, it is more convenient to position the packaging box at one side position, ensuring the positioning effect. When the power supply of the electromagnet is turned off, under the action of the compression spring 28, the push rod 29 and the sleeve 19 are reset, facilitating the positioning work through components such as the transmission rod 6.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
