A strip groove 3411 is provided, and the strip groove 3411 is circular in shape with a convex side, and the convex positions of the strip grooves 3411 on both sides are in opposite directions. The No. 1 turntable 341 and the No. 2 turntable 342 are respectively provided with a No. 1 sliding rod 35 and a No. 2 sliding rod 36 on the side close to the strip groove 3411. The No. 1 sliding rod 35 and the No. 2 sliding rod 36 are fixedly connected with a protruding block 351 on the side close to the strip grooves 3411 on both sides. The No. 1 sliding rod 35 is fixedly connected with a No. 1 screening plate 352 at the bottom away from the protruding block 351, and the No. 2 sliding rod 36 is fixedly connected with a No. 2 screening plate 361 at the top away from the protruding block 351.

[0040] like Figure 8-Figure 9As shown, the outer wall of the upper end of the support frame 21 is fixedly connected with a tidying chamber 4, and a tidying assembly 5 is arranged on the inner side of the tidying chamber 4. The electric telescopic rod 11 passes through the top of the classification chamber 1 and the top of the tidying chamber 4. The tidying assembly 5 includes an extrusion column 51, and the top of the extrusion column 51 is rotatably connected with a connecting rod 52.

[0041] It can be seen from this that when it is necessary to sort and organize different express deliveries, Figure 3-Figure 7As shown, when the staff puts the piles of express delivery into the feed port 12, the sprocket 22 rotates under the drive of the motor 211, and the sprocket 22 drives the chain 23 to rotate on the outside of the sprocket 22. When the chain 23 rotates, the sliding block 231 on the chain 23 is driven to rotate together. At this time, when the chain 23 drives the sliding block 231 to move up and down, and slides left and right when it rotates to the end position of the chain 23, the sliding block 231 will be driven in the process of sliding up and down. The sliding frame 212 slides up and down on the outer wall of the support frame 21, and the sliding frame 212 drives the No. 1 rack 213 to slide up and down. At the same time, the No. 1 rack 213 that slides up and down drives the No. 1 gear 31 to rotate. At the same time, the No. 1 gear 31 drives the rotating rod 32, the No. 1 rotating disk 341 and the No. 2 rotating disk 342 to rotate together. At this time, the strip grooves 3411 distributed in opposite directions on both sides of the No. 1 rotating disk 341 and the No. 2 rotating disk 342 will limit the protrusions on the No. 1 sliding rod 35 and the No. 2 sliding rod 36 351, then after the No. 1 turntable 341 rotates a certain angle, it will gradually slide from the circular position of the strip groove 3411 to the raised position. At this time, it is restricted by the raised position of the strip groove 3411, pushing the raised block 351 and the No. 1 sliding rod 35, so that the No. 1 sliding rod 35 on both sides drives the No. 1 screening plate 352 to approach each other, and the No. 2 sliding rod 36 will gradually slide from the raised position to the circular position, then the strip groove 3411 will pull the raised block 351, the No. 2 sliding rod 36 and the No. 2 screening plate 352 to move closer to each other. The separating plate 361 forms a misalignment difference between the second screening plate 361 and the first screening plate 352, and the express is clamped when it falls to the position of the first screening plate 352 on both sides, and it stays briefly between the continuously staggered second screening plate 361 and the first screening plate 352 and falls onto the first conveying track 13, and is conveyed to the end by the continuously moving sliding block 231 and the placing rod 232 through the roller of the first conveying track 13 to the second conveying track 14;

[0042] Among them, when the placement rod 232 delivers the express to the bottom position of the tidying chamber 4, as Figure 3 and Figure 8-Figure 9 As shown, if the express delivered to the bottom of the tidying chamber 4 is a carton packaged express, the carton packaged express will push the squeezing column 51 upwards. At this time, the squeezing column 51 will drive the connecting rods 52 on both sides to rotate upwards during the upward movement. At the same time, the side plates 53 on both sides will slide downward a short distance with the connecting column 521 as the fulcrum. At the same time, the connecting column 521 will also rotate a certain angle, and the connecting column 521 will drive the second gear 522 to rotate a certain angle. At this time, the second gear 522 drives the second rack 541 and the column 54 to slide downward a short distance. In the process of the column 54 sliding downward, it will also drive the tidying plate 542 and the push plate 543 to slide downward together. Fig. 9As shown, in the process of the push plate 543 and the tidying plate 542 moving downward, the carton packaged express is placed flat by the inclined surface inside the push plate 543 and the tidying plate 542, and the carton packaged express is pushed to the outside of the placement rod 232 by the inclined surface of the push plate 543 for a distance, so that when the sliding block 231 and the placement rod 232 slide to the position of the second conveying track 14, the carton packaged express will be transported out from the outside of the second conveying track 14, while the plastic bag packaged express will not touch the squeezing column 51 due to its soft material and flat shape, and will be transported to the inside of the second conveying track 14. At this time, the transported carton packaged express or plastic bag packaged express is transported to different positions for classification;

[0043] In addition, when the express continues to be transported after being squeezed by the squeezing column 51, the pressure on the squeezing column 51 to push it upward will gradually decrease, and after the touch sensor at the bottom of the tidying chamber 4 is no longer under force, the electric telescopic rod 11 will extend to restore the tidying component 5 to its initial state. Then, when the carton-packed express pushes up the squeezing column 51 and touches the touch sensor, the electric telescopic rod 11 will contract with the same amplitude as the upward movement of the squeezing column 51.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
