[0053] As Figure 7 shown in the figure, the ejecting cylinder 61 of the finished product ejecting mechanism 6 is installed under the pedestal 1. The output shaft at the lower end of the ejecting cylinder 61 is installed with an ejecting connecting plate 62. Four second guide shafts 64 are installed at the four corners of the ejecting connecting plate 62. The second guide shafts 64 penetrate through the second bush 63 in the pedestal 1 vertically. Two ejecting plates 65 are installed at the top ends of the second guide shafts 64. A cylinder mounting plate 66 is also provided on the pedestal 1. A sliding ruler cylinder 67 is installed on the cylinder mounting plate 66. A dial 68 is installed on the sliding block of the sliding ruler cylinder 67. The dial 68 moves back and forth with the sliding ruler cylinder 67 to eject the product.

[0054] When the small and fast inserting machine of this embodiment is in use, the electricity is turned on, the air pressure is adjusted to the specified scale, the fixtures at each position are assembled and adjusted. The materials are placed in the U-shaped cardboard hopper 37, the partition hopper 48 and the feeding track 52. The equipment start button is pressed, and the bending fixture 38 moves to the bending mechanism 3 along with the lead screw displacement structure 2.

[0055] The bending mechanism 3 is provided with a position detection sensor. After the position detection sensor detects that it is in place, the first electric cylinder 31 moves upward the first suction cup 36 to the height for sucking the U-shaped cardboard. After the first suction cup 36 sucks the U-shaped cardboard from the U-shaped cardboard hopper 37, the first electric cylinder 31 descends, pulls the U-shaped cardboard into the bending jig 38 for bending. After the bending is completed, the first suction cup 36 stops sucking air.

[0056] The screw rod displacement structure 2 transfers the bending jig 38 to the partition inserting mechanism 4. The lifting guide rail 43 drives the U-shaped cardboard pressing plate 45 to descend. After pressing the U-shaped cardboard in the bending jig 38 to the bottom to form it, it rises to the height for taking out the partition from the partition hopper 48. At the same time, the screw rod displacement structure 2 moves to the position for inserting the first partition. The flipping cylinder 46 flips upward, and the suction cup jig 47 sucks the partition from the partition hopper 48. After the sucking is completed, the flipping cylinder 46 flips downward, and the lifting guide rail 43 descends to insert the partition into the U-shaped cardboard in the bending jig 38.

[0057] After the first partition is inserted into the U-shaped cardboard in place, the suction cup jig 47 stops sucking air. The lifting guide rail 43 rises to the height for taking out the partition from the partition hopper 48, continues to suck the second partition. At the same time, the screw rod displacement structure 2 transfers the bending jig 38 to move to the second partition inserting position, and repeats the above actions of taking material, inserting, and moving until the number of inserted partitions is sufficient.

[0058] The screw rod displacement structure 2 transfers the bending jig 38 to the middle board inserting mechanism 5. The second electric cylinder 55 rises to the material taking position, and the pushing wheel 53 pushes the middle board cardboard on the feeding track 52 to slide downward until the middle board cardboard is sucked by the suction cup plate 58. After the sucking is completed, the second electric cylinder 55 descends to the inserting position and inserts the middle board cardboard into the combined product of the U-shaped cardboard and the partition. After the middle board cardboard is inserted, the middle board suction cup 58 stops sucking air, and the second electric cylinder 55 rises again to the material taking position.

[0059] The screw rod displacement structure 2 transfers the bending jig 38 to the finished product extracting mechanism 6. The ejecting cylinder 61 rises, and the ejecting plate 65 ejects the packaged box partition (the combined product of the U-shaped cardboard, the partition, and the middle board cardboard) inserted with inserts out of the bending jig 38. The sliding ruler cylinder 67 moves backward, driving the dial ruler 68 to push the packaged box partition backward to extract it.

[0060] Finally, the sliding ruler cylinder 67 and the ejecting cylinder 61 return to the origin. The screw rod displacement structure 2 transfers the bending jig 38 back to the bending mechanism 3, and is detected to be in place by the position detection sensor again to start the next process.

[0061] 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 it; 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.
