[0035] The reciprocating motion component 5 includes a rod body 501, a rotating shaft 502 rotatably connected to the first axis frame 402 is provided at the bottom of the rod body 501, a first strip slide groove 505 and a second strip slide groove 506 are provided on the rod body 501 from bottom to top, an electric telescopic swing arm 504 is provided between the first strip slide groove 505 and the second axis frame 403, the fixed end of the electric telescopic swing arm 504 is rotatably connected to the second axis frame 403, a first driving motor 503 is provided on the side of the mounting frame 401 away from the rod body 501, the driving shaft of the first driving motor 503 is connected to the fixed end of the electric telescopic swing arm 504, and the telescopic end of the electric telescopic swing arm 504 is slidably connected to the first strip slide groove 505.

[0036] Through the above structure, the first drive motor 503 is started, and the first drive motor 503 drives the electric telescopic swing arm 504 to rotate. The telescopic end of the electric telescopic swing arm 504 slides and rotates with the first strip slide groove 505, driving the rod body 501 to swing around the rotating shaft 502, so that the end of the rod body 501 close to the second strip slide groove 506 swings back and forth. By adjusting the length of the electric telescopic swing arm 504, the swing stroke distance of the end of the rod body 501 close to the second strip slide groove 506 can be adjusted. The extension and retraction of the electric telescopic swing arm 504 is a prior art, so it is not described here.

[0037] Combined with Figure 1 , Attachment Figure 3 , Attachment Figure 4, Attachment Figure 6 :

[0038] The limiting slide 9 includes a limiting slide body 901, a trapezoidal limiting slide groove 902 is provided on one side of the limiting slide body 901 close to the first through groove 11, and a second through groove 903 communicating with the trapezoidal limiting slide groove 902 is provided in the limiting slide body 901;

[0039] The bidirectional propulsion device 8 includes an S-shaped connecting rod 801, one end of the S-shaped connecting rod 801 passes through the second through groove 903, and the other end is slidably connected to the second strip slide groove 506.

[0040] Through the above structure, one end of the rod body 501 close to the second strip slide groove 506 drives one end of the S-shaped connecting rod 801 to move during the swinging process. Since the S-shaped connecting rod 801 is slidingly connected to the second strip slide groove 506, under the limiting action of the trapezoidal limiting slide groove 902 and the trapezoidal slider 802, the horizontal height of the uncovered box body 804 remains unchanged and moves back and forth along the first through groove 11.

[0041] Combined with Figure 1 , Attachment Figure 3 and attached Figure 7 :

[0042] The coverless box body 804 has a cavity inside, with limit mounting posts 807 at both ends of the cavity, and springs 808 on the limit mounting posts 807. Two springs 808 have symmetrically mounted L-shaped sliders 805 on them. The L-shaped sliders 805 can move up and down in the cavity, and the protruding ends of the two L-shaped sliders 805 are rotatably connected to rollers 806.

[0043] Through this structure, when the uncovered box body 804 moves to one end of the bottom of the corrugated cardboard stack, the L-shaped slider 805 located on the outside quickly pops up under the action of the spring 808 below, and when the uncovered box body 804 moves from one end of the bottom of the corrugated cardboard stack to the other end, the protruding end of the L-shaped slider 805 pushes out the corrugated cardboard at the bottom of the corrugated cardboard stack, thereby separating it from the corrugated cardboard stack, and the contact area between the corrugated cardboard and the belt conveyor device gradually increases. The belt conveyor device conveys the corrugated cardboard to the far end through friction, thereby completely separating the corrugated cardboard from the corrugated cardboard stack. During the return process of the uncovered box body 804, the roller 806 rolls and rubs against the corrugated cardboard to prevent the penultimate corrugated cardboard from being driven. When the uncovered box body 804 moves to the end of the return journey, another L-shaped slider 805 pushes the penultimate corrugated cardboard (at this time located at the bottom) in reverse to the belt conveyor device at the other end, and so on.

[0044] Combined with Figure 2 , Attachment Figure 8 , Attachment Fig. 9 and attached Fig.10 :

[0047] Through the above structure, the telescopic cylinder 702 is controlled to move the four straightening devices 6 to a suitable position. After the corrugated cardboard stack is placed on the supporting plate 1, the four telescopic cylinders 702 are controlled simultaneously to move the corrugated cardboard stack to the central position. According to the thickness of the corrugated cardboard, the second driving motor 6026 at both ends of the first through groove 11 is controlled to drive the gear 6025 to rotate and cooperate with the tooth plate 604, thereby adjusting the gap distance between the bottom of the straightening shell 601 and the supporting plate 1.

[0048] In the specific implementation of the present invention, the corrugated cardboard stack is first placed on the supporting plate 1, and the four telescopic cylinders 702 are controlled to move the corrugated cardboard stack to the central position. According to the thickness of the corrugated cardboard, the second driving motor 6026 at both ends of the first through slot 11 is controlled to drive the gear 6025 to rotate, and cooperate with the tooth plate 604, so as to adjust the gap distance between the bottom of the straightening housing 601 and the supporting plate 1;

[0049] According to the length of the corrugated paper, the length of the electric telescopic swing arm 504 is adjusted, thereby adjusting the swing stroke distance of one end of the rod body 501 close to the second strip slide groove 506, and then adjusting the reciprocating motion stroke distance of the uncovered box body 804, and starting the first drive motor 503, the first drive motor 503 drives the electric telescopic swing arm 504 to rotate, and the telescopic end of the electric telescopic swing arm 504 slides and rotates with the first strip slide groove 505, driving the rod body 501 to swing around the rotating shaft 502 as the center, so that the end of the rod body 501 close to the second strip slide groove 506 swings back and forth, and the end of the rod body 501 close to the second strip slide groove 506 drives one end of the S-shaped connecting rod 801 to move during the swinging process, because the S-shaped connecting rod 801 is slidably connected to the second strip slide groove 506, so under the limiting action of the trapezoidal limiting slide groove 902 and the trapezoidal slider 802, the horizontal height of the uncovered box body 804 remains unchanged, and reciprocates along the first through groove 11;

[0050] When the uncovered box body 804 moves to one end of the bottom of the corrugated cardboard stack, the L-shaped slider 805 located on the outside quickly pops up under the action of the spring 808 below, and when the uncovered box body 804 moves from one end of the bottom of the corrugated cardboard stack to the other end, the protruding end of the L-shaped slider 805 pushes out the corrugated cardboard at the bottom of the corrugated cardboard stack, thereby separating it from the corrugated cardboard stack, and the contact area between the corrugated cardboard and the belt conveyor gradually increases. The belt conveyor conveys the corrugated cardboard to the far end through friction, thereby completely separating the corrugated cardboard from the corrugated cardboard stack. During the return process of the uncovered box body 804, the roller 806 rolls and rubs against the corrugated cardboard to prevent the penultimate corrugated cardboard from being driven. When the uncovered box body 804 moves to the end of the return journey, another L-shaped slider 805 pushes the penultimate corrugated cardboard (at this time at the bottom) in reverse to the belt conveyor at the other end, and so on.
