[0022] The following further elaborates on the present application in conjunction with the attached Figure 1-6 for a more detailed description of the present application.

[0023] An embodiment of the present application discloses a packing device for packing cardboard boxes in sequence. Refer to Figure 1 and Figure 2, including the equipment body 1, the equipment body 1 includes a conveyor 11 and a bundling machine 12. The bundling machine 12 is fixedly connected above the conveyor 1. Two sets of pushing mechanisms 2 are installed on the conveyor 11. The two sets of pushing mechanisms 2 are respectively located on both sides of the bundling machine 12, and the two sets of pushing mechanisms 2 are arranged in central symmetry. When it is necessary to bundle a cardboard box, first place the cardboard box on the conveyor 11. The conveyor 11 transports the cardboard box to the lower part of the bundling machine 12. The bundling machine 12 bundles the cardboard box. Then start the two sets of pushing mechanisms 2. The two sets of pushing mechanisms 2 respectively push two diagonals of the cardboard box to move, so that the cardboard box rotates around its center. When the cardboard box rotates 90 degrees, the bundling machine 12 bundles the cardboard box again, solving the problem of low bundling efficiency of the cardboard box.

[0024] Refer to Figures 2 to 4 , the pushing mechanism 2 includes a mounting plate 21. The mounting plate 21 is fixedly connected to the side wall of the conveyor 11. A mounting groove 211 is horizontally opened at the top of the mounting plate 21. A pushing motor 22 is fixedly connected to the end face of the mounting plate 21 away from the conveyor 11. A pushing screw 23 is rotatably installed in the mounting groove 211. The output shaft of the pushing motor 22 is fixedly connected to the pushing screw 23.

A pushing plate 25 is installed on the mounting block 24. The pushing plate 25 can contact the cardboard box. Start the pushing motor 22. The pushing motor 22 drives the pushing screw 23 to move. The pushing screw 23 drives the mounting block 24 to move. The mounting block 24 drives the pushing plate 25 to move. The pushing plate 25 pushes the corner of the cardboard box to move.

[0025] Refer to Figures 2 to 4 , a pushing mechanism 3 is installed in the pushing mechanism 2 at the front end of the conveying direction of the conveyor 11. The mounting block 24 and the pushing plate 25 at the rear end of the conveying direction of the conveyor 11 are fixedly connected. The pushing mechanism 3 includes a pushing plate 31. The pushing plate 31 is fixedly connected to the top of the mounting block 24. A pushing groove 311 is horizontally opened at the top of the pushing plate 31.

[0026] When the width of the cardboard box is less than the distance between the two pushing plates 25, the two pushing plates 25 cannot push the cardboard box to rotate by 90 degrees. At this time, the pushing screw 23 drives the pushing screw 32 to rotate through the transmission mechanism 4. The pushing screw 32 drives the pushing block 33 to move, and the pushing block 33 drives the pushing plate 25 to move. The pushing plate 25 can push the cardboard box to slide along the conveying direction of the conveyor 11. When both opposite sides of the cardboard box are in contact with the pushing plate 25, the cardboard box can be rotated by 90 degrees, so as to pack the cardboard box, increasing the application range of the packing equipment. And then start the conveyor 11 again. The conveyor 11 drives the cardboard box to move under the strapping machine 12, and the packing position of the strapping machine 12 can be adjusted.

[0027] Refer to Figures 3 to 5 , the end of the pushing screw 23 away from the pushing motor 22 is a smooth section. A pushing spring 26 is fixedly connected to the inner wall of the installation groove 211. The pushing spring 26 can abut against the installation block 24. The transmission mechanism 4 includes a first transmission shaft 41 and a second transmission shaft 42.

[0028] During the rotation of the pushing screw 23, the pushing screw 23 drives the installation block 24 to move, the installation block 24 drives the pushing plate 31 to move, the pushing plate 31 drives the first transmission shaft 41 and the second transmission shaft 42 to move, the first transmission shaft 41 drives the second gear 44 to move. At the same time, the pushing screw 23 drives the first gear 43 to rotate. When the second gear 44 meshes with the first gear 43, the first gear 43 drives the second gear 44 to rotate, the second gear 44 drives the first transmission shaft 41 to rotate, the first transmission shaft 41 drives the second transmission shaft 42 to rotate through the transmission belt 45, the second transmission shaft 42 drives the first bevel gear 46 to rotate, the first bevel gear 46 drives the second bevel gear 47 to rotate, and the second bevel gear 47 drives the pushing screw 32 to rotate, so as to push the cardboard box to move.

[0029] Refer to Figure 4 and Figure 5, a locking groove 212 is formed on the inner wall of the installation groove 211. The locking mechanism 5 includes a locking spring 51 and a locking block 52. The locking spring 51 is fixedly connected to the inner wall of the locking groove 212. The locking block 52 is placed in the locking groove 212 and is fixedly connected to the locking spring 51. A plugging groove 241 for the locking block 52 to insert is formed on the side wall of the installation block 24. A locking inclined surface 521 is formed on the end surface of the locking block 52 facing the installation block 24. The locking inclined surface 521 can contact the side of the installation block 24. An unlocking mechanism 6 for driving the locking block 52 to be pulled out from the plugging groove 241 is installed on the pushing plate 31; during the movement of the installation block 24, the installation block 24 pushes the locking block 52 to move through the locking inclined surface 521, compressing the locking spring 51. When the locking block 52 is opposite to the plugging groove 241, the locking spring 51 pushes the locking block 52 to insert into the plugging groove 241 to lock the installation block 24. At the same time, the installation block 24 compresses the pushing spring 26. When the pushing motor 22 rotates reversely, the pushing motor 22 first drives the pushing plate 25 to return to one end of the pushing groove 311 close to the installation plate 21. At this time, the unlocking mechanism 6 drives the locking block 52 to be pulled out from the plugging groove 241, and the pushing spring 26 pushes the installation block 24 to be threadedly connected with the pushing screw rod 23, and the pushing screw rod 23 drives the installation block 24 to return to the initial position.

When the unlocking inclined surface 611 contacts the side of the second unlocking rod 62, the first unlocking rod 61 pushes the second unlocking rod 62 to move through the unlocking inclined surface 611. The second unlocking rod 62 drives the locking block 52 to be received in the locking groove 212. When the pushing block 33 moves towards the side close to the strapping machine 12, the second unlocking rod 62 pushes the first unlocking rod 61 to move, and the locking block 52 is inserted into the plugging groove 241 to lock the installation block 24. When the pushing block 33 returns, the pushing block 33 can push the second unlocking rod 62 to move through the first unlocking rod 61, so that the locking block 52 is pulled out from the plugging groove 241.

The plurality of blowing nozzles 731 are divided into two groups, and the inclination directions of the two groups of blowing nozzles 731 are opposite; during the process of packing the cardboard box, the blowing air pump 72 is started. The blowing air pump 72 blows air into the blowing air pipe 73 through the connecting pipe 74 and blows out from the blowing nozzles 731 to clean the debris generated during the packing process, avoiding the situation that the debris falls into the conveyor 11 and causes damage to the conveyor 11.

[0032] Refer to Figure 3 and Figure 6 , a vertical groove 711 is formed on the side wall of the vertical plate 71. A vertically arranged dust blowing screw 75 is rotatably installed in the vertical groove 711. A dust blowing block 76 is slidably placed in the vertical groove 711.
