[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Reference Figures 1-10 A paper collection device for corrugated cardboard processing includes a body 1 and a cardboard 6, and the cardboard 6 is composed of corrugated cardboard. The body 1 is provided with a rotating base plate 2, an upper pressing plate 3, a side moving plate 4 and a limiting long plate 5. Figure 2 As shown, a rotating base plate 2 is rotatably arranged at the upper end of the machine body 1, and the rotating base plate 2 is an L-shaped plate mechanism. When the rotating base plate 2 is in an inclined state, multiple cardboards 6 are stacked at a right angle of a rotating base plate 2 by guiding the bottom end of the tilted rotating base plate 2. At the same time, the right angle of the rotating base plate 2 limits the bottom end and the rear end of the cardboard 6, and an upper pressing plate 3 is slidably arranged at one end of a rotating base plate 2, and the upper pressing plate 3 is a cross-shaped plate structure. Two side movable plates 4 are symmetrically slidably arranged on a rotating base plate 2 at the upper pressing plate 3, first allowing the upper pressing plate 3 to compact the upper end of the cardboard 6, and then allowing the two side movable plates 4 to limit the left and right sides of the cardboard 6, and prevent the two side movable plates 4 from continuing to move toward the cardboard 6, so as to avoid the cardboard 6 from bending at the middle end due to excessive limiting driving force of the two side movable plates 4. At the same time, two sets of limiting long plates 5 are slidably arranged at the two side movable plates 4;

[0038] Preferably, a driving mechanism is provided on the body 1, the driving mechanism is arranged at the body 1, and the driving mechanism is used to adjust the inclination state of the rotating base plate 2. When the rotating base plate 2 is in an inclined state, the cardboard 6 is guided to move to a right angle to the rotating base plate 2. When multiple cardboards 6 are stacked, the rotating base plate 2 and the multiple cardboards 6 are in a horizontal state to facilitate the even removal of the multiple cardboards 6; an adjustment mechanism is provided at the body 1, and the adjustment mechanism is used to allow the two sets of limiting long plates 5 to limit the multiple stacked cardboards 6 one by one.

[0039] The driving mechanism includes a rotating shaft 7, a driving motor 8 and a connecting member 9. The rotating shaft 7 is rotatably installed at the upper end of the body 1, the driving motor 8 is fixedly installed at the side end of the body 1, and the output end of the driving motor 8 is fixedly connected to the rotating shaft 7. The connecting member 9 is fixedly sleeved on the rotating shaft 7, and the upper end of the connecting member 9 is fixedly connected to the bottom end of the rotating substrate 2, and the rotating substrate 2 is rotated by the driving motor 8.

[0040] Preferably, the driving mechanism further comprises a first support block 10 and a second support block 11, both of which are fixedly connected to the upper end of the body 1. Figure 2 As shown, the cross-section of the first support block 10 is a right-angled trapezoid, and the cross-section of the second support block 11 is a rectangle. When the rotating substrate 2 is in a tilted state, the bottom end of the rotating substrate 2 abuts against the hypotenuse of the first support block 10 to prevent the rotating substrate 2 from further tilting. When the rotating substrate 2 is in a horizontal state, the bottom end of the rotating substrate 2 abuts against the upper end of the second support block 11 to prevent the rotating substrate 2 from further rotating.

[0041] Preferably, the adjustment mechanism includes a vertical slide groove 12, a vertical telescopic rod 13, a horizontal slide groove 14 and a horizontal telescopic rod 15. A vertical slide groove 12 is opened at the front end of a rotating base plate 2, and the vertical telescopic rod 13 is fixedly installed in the vertical slide groove 12. The upper pressure plate 3 is slidably sleeved in the vertical slide groove 12, and the upper pressure plate 3 is fixedly connected to the output end of the vertical telescopic rod 13, and the upper pressure plate 3 is vertically moved by the vertical telescopic rod 13. Two horizontal slide grooves 14 are symmetrically opened at the front end of a rotating base plate 2, and two horizontal telescopic rods 15 are respectively fixedly installed in the two horizontal slide grooves 14, and the two side movable plates 4 are respectively slidably sleeved in the two horizontal slide grooves 14, and a side movable plate 4 is fixedly connected to a horizontal telescopic rod 15, and the side movable plate 4 is laterally moved by the horizontal telescopic rod 15.

[0042] The adjustment mechanism also includes a through square hole 16, a mounting bracket 17 and a guide long slot 18. Two groups of through square holes 16 are respectively opened on the inner and outer sides of the two side movable plates 4. The two mounting brackets 17 are respectively fixedly connected to the side ends of the two side movable plates 4. The mounting bracket 17 is an L-shaped plate structure, and two groups of guide long slots 18 are respectively opened at the two mounting brackets 17.

[0043] Preferably, the adjustment mechanism also includes a sliding block 19 and a fixing spring 20. The two groups of sliding blocks 19 are slidably mounted in the two groups of guide long grooves 18, and the two groups of sliding blocks 19 are fixedly connected to the two groups of limiting long plates 5 respectively. Under the guidance of the guide long grooves 18, the limiting long plates 5 pass through the inner and outer sides of the through square holes 16 in sequence and limit the front end of the cardboard 6. One end of the two groups of fixing springs 20 are fixedly mounted on the two mounting brackets 17, and the other end of the two groups of fixing springs 20 are fixedly connected to the two groups of limiting long plates 5 respectively. When the limiting long plates 5 are locked on the mounting brackets 17, the limiting long plates 5 squeeze the fixing springs 20. When the limiting long plates 5 are unlocked, the fixing springs 20 in the squeezed state provide elastic force to allow the limiting long plates 5 to move toward the front end of the cardboard 6.

[0044] Preferably, the adjustment mechanism also includes a mounting platform 21, a rotating shaft 22 and a limiting rotating rod 23. The two groups of mounting platforms 21 are respectively fixedly installed on the inner sides of the two side movable plates 4, and the two groups of rotating shafts 22 are respectively rotatably installed on the two groups of mounting platforms 21. The two groups of limiting rotating rods 23 are respectively fixedly connected to the two groups of rotating shafts 22. When one end of the two groups of limiting rotating rods 23 is respectively against the two groups of limiting long plates 5, the two groups of limiting long plates 5 are locked.

[0045] The adjustment mechanism also includes a reset torsion spring 24 and a limiting square hole 25. The two sets of reset torsion springs 24 are fixedly sleeved on the two sets of rotating shafts 22 respectively. The two sets of limiting square holes 25 are respectively opened at the outer sides of the two side movable plates 4. When the two side movable plates 4 limit the left and right sides of the cardboard 6 and resist each other, the left and right ends of an upper pressing plate 3 are movably sleeved in the two limiting square holes 25 at the same height, and the left and right ends of an upper pressing plate 3 are movably resisted against the other ends of the two limiting rotating rods 23 respectively, so that one end of the two limiting rotating rods 23 is away from the two limiting long plates 5 and the locking state of the two limiting long plates 5 is released.

[0046] It is particularly noted that when the cardboards 6 are stacked one by one, the heights of the multiple cardboards 6 increase one by one, so that the height of the upper pressure plate 3 located at the upper ends of the multiple cardboards 6 also increases accordingly, and the limiting long plates 5 of the corresponding heights are unlocked one by one, and then the front ends of the multiple cardboards 6 are limited in sequence from bottom to top; and when it is necessary to reset the limiting long plates 5, first let the left and right ends of the upper pressure plate 3 respectively movably offset against the other ends of the two limiting rotating rods 23, so that one end of the two limiting rotating rods 23 is away from the two limiting long plates 5, and then pull the two limiting long plates 5 to move to the mounting bracket 17, and drive the two side movable plates 4 away from the upper pressure plate 3, and under the elastic force of the reset torsion spring 24, let the two limiting rotating rods 23 return to their initial positions, and at the same time loosen the two limiting long plates 5, so that one end of the two limiting rotating rods 23 offsets the two limiting long plates 5, and locks the two limiting long plates 5.

[0047] The present invention can be explained through the following operation mode:

[0048] First, start the drive motor 8, and let the output end of the drive motor 8 drive the rotating substrate 2 through the rotating shaft 7 and the connecting piece 9. Figure 2 As shown, the rotating substrate 2 is rotated toward the first supporting block 10, and the bottom end of the rotating substrate 2 is abutted against the oblique edge of the first supporting block 10 to prevent the rotating substrate 2 from tilting further;

[0049] Then, the cardboard 6 is conveyed to the top of the rotating base plate 2 by the conveyor belt. The cardboard 6 falls to the bottom of the rotating base plate 2 under the action of gravity. Guided by the bottom of the inclined rotating base plate 2, the cardboard 6 moves to the right angle of the rotating base plate 2. Then, the vertical telescopic rod 13 is activated to move the upper pressing plate 3 downward along the vertical slide 12 until the upper pressing plate 3 contacts the upper end of the cardboard 6 to compact the upper end of the cardboard 6.

[0050] And start the two transverse telescopic rods 15 to allow the two side movable plates 4 to move toward the cardboard 6 until the two side movable plates 4 respectively abut against the two sides of the cardboard 6, and at the same time, the left and right ends of the upper pressing plate 3 respectively enter the two limiting square holes 25 at the same height, and the left and right ends of the upper pressing plate 3 respectively abut against one end of the two limiting rotating rods 23, so that the other ends of the two limiting rotating rods 23 are deflected, and the other ends of the two limiting rotating rods 23 are respectively away from the two limiting long plates 5, and the two limiting long plates 5 move toward the through square holes 16 under the elastic force of the two fixing springs 20 until the two limiting long plates 5 move to the front end of the cardboard 6 and limit the front end of the cardboard 6, then let the two side movable plates 4 move away from the cardboard 6, and then let the upper pressing plate 3 move upward, so that the next cardboard 6 can be stacked to the right angle of the rotating base plate 2, and repeat the above operation to limit and place multiple cardboards 6.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
