[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0040] See also Figures 1 to 10In an embodiment of the present invention, a cardboard cutting and stacking device includes: an operating table 1, a fixed plate 2, a conveying plate 22, a transverse plate 29, a longitudinal cutting mechanism, a cutting disc 14, an equidistant adjustment mechanism, a cutting knife 25, a transverse cutting mechanism, a cardboard stacking mechanism and a guide assembly and a receiving plate 34. Through the cooperation of the transverse cutting mechanism and the longitudinal cutting mechanism, the cutting size of the cardboard can be adjusted according to demand, and under the action of the cardboard stacking mechanism, the effect of not stopping the machine to replace the stacking plate after stacking to a certain height can be achieved. When the cardboard needs to be cut, the cardboard will be placed on the conveying plate 22. When the cardboard passes through the cutting disc 14, the longitudinal cutting mechanism cuts the cardboard into multiple strips. The cardboard continues to move. When the cardboard passes through the cutting knife 25, the transverse cutting mechanism cuts the cardboard into multiple pieces evenly. At the same time, the cut cardboard is cut into multiple pieces in the transverse cutting mechanism. Under the action of the cutting mechanism, it is transported to the designated position. At this time, the cardboard will continue to fall onto the receiving plate 34, and under the action of the cardboard stacking mechanism, the height of the receiving plate 34 is continuously lowered to ensure that the cardboard can smoothly enter the receiving plate 34. At the same time, under the action of the guide component, it is ensured that the receiving plate 34 will not deviate in the horizontal direction and is always in the optimal receiving position until this receiving plate 34 is fully stacked. Under the action of the cardboard stacking mechanism and the guide component, this receiving plate 34 deviates from the stacking position, and the other receiving plate 34 is moved to the stacking position for stacking, so as to achieve the effect of replacing the stacking plate without stopping the machine. If the size of the cardboard needs to be changed, under the action of the spacing adjustment mechanism, the cutting disc 14 is driven to move closer or farther away from each other through the longitudinal cutting mechanism, and the speed of the cutting knife 25 is controlled by the transverse cutting mechanism, so as to achieve the effect of adjusting the cardboard cutting size.

[0041] The details are as follows, including:

[0042] An operating table 1, on which a symmetrically arranged fixed plate 2 is fixedly mounted, a conveying plate 22 is also fixed on the operating table 1, and a transverse plate 29 is fixed on the fixed plate 2;

[0043] See also Figure 1 、 Figure 3-Figure 7, a longitudinal cutting mechanism is provided on the fixed plate 2, and a plurality of cutting discs 14 are provided on the longitudinal cutting mechanism. The longitudinal cutting mechanism can drive the cutting disc 14 to move in the vertical direction and drive the cutting disc 14 to cut the cardboard placed on the conveying plate 22. The longitudinal cutting mechanism includes a plurality of supporting sleeves 12 provided on the operating table 1 and distributed at equal distances. A supporting plate 13 is fixed to one end of the supporting sleeve 12 facing the operating table 1. A card slot 16 is provided on the fixed plate 2, and a lifting group connected to the card slot 16 and the cutting disc 14 is provided on the fixed plate 2. Part, the supporting sleeve 12 is fixedly connected to the cutting disc 14 and is connected to the equidistant adjustment mechanism, wherein the lifting assembly includes a No. 3 guide rail 18 fixedly mounted on the fixed plate 2 and symmetrically arranged, and a sliding plate 19 is slidably mounted on the No. 3 guide rail 18, and a No. 1 motor 20 is fixed on the sliding plate 19; the lifting assembly also includes a transmission rod 15 rotatably mounted on the sliding plate 19 and passing through the slot 16, a No. 1 cylinder 17 movably connected to the transmission rod 15 is fixed on the fixed plate 2, and the transmission rod 15 is connected to the output shaft of the No. 1 motor 20 and is rotatably connected to the cutting disc 14.

[0044] In detail, during cardboard production, in order to meet customer needs, the cardboard needs to be cut into specified sizes. Therefore, the cardboard needs to be cut longitudinally by the cutting disc 14 so that the width of the cardboard meets the customer's requirements. The cutting disc 14 can be divided into a cutting bracket and a cutting knife. The transmission rod 15 passes through the cutting bracket and is fixedly connected to the cutting knife. In the initial state, under the action of the equidistant adjustment mechanism, the spacing between the cutting discs 14 is minimized. Under the action of the No. 1 cylinder 17, the transmission rod 15 is located at the end of the stroke toward the operating table 1 to ensure that the cutting disc 14 can act on the cardboard. The cardboard is located on the conveying plate 22 and, under the action of the front-end conveying, the cardboard always moves toward the cutting disc 14. At this time, the No. 1 motor 20 works and drives the cutting knife to rotate through the transmission rod 15. When the cardboard moves to the contact position with the cutting knife, the cutting knife divides the cardboard into multiple strips of cardboard of the same size. The cut cardboard will continue to move and, under the action of the transverse cutting mechanism and the cutting knife 25, the cardboard is cut transversely, so that the long cardboard is divided into blocks of cardboard of the same size.

[0045] Preferably, when the cutting size of the cardboard needs to be adjusted, in order to ensure that the cutting disc 14 does not interfere with the cardboard, the No. 1 cylinder 17 works and drives the transmission rod 15 to move along the length direction of the cardboard 16 and move in the direction away from the operating table 1. The transmission rod 15 also drives the sliding plate 19 to move along the length direction of the No. 3 guide rail 18 and drives the No. 1 motor 20 to move, so that the height of the cutting disc 14 increases and separates from the cardboard. The cutting disc 14 also drives the support sleeve 12 and the support plate 13 to move to ensure that the support sleeve 12 does not separate from the equidistant adjustment mechanism. At this time, under the action of the equidistant adjustment mechanism, the support sleeve 12 is controlled to move in the direction away from each other, and the distance between each support sleeve 12 always remains equal. The support sleeve 12 also drives the cutting disc 14 to move through the support plate 13 to increase the distance between the cutting discs 14. When the adjustment is completed, under the action of the No. 1 cylinder 17, the transmission rod 15 is driven back to the initial height, so that the cutting knife fits the cardboard again and the cardboard is split, thereby achieving the effect of quickly adjusting the cardboard cutting size.

[0046] See also Figure 1 、 Figure 3-Figure 7 , an equidistant adjustment mechanism is provided on the fixed plate 2 and is connected to the longitudinal cutting mechanism. The equidistant adjustment mechanism can drive the cutting disc 14 to move equidistantly closer to or farther from each other through the longitudinal cutting mechanism. The equidistant adjustment mechanism includes a No. 1 guide rail 3 fixedly mounted on the fixed plate 2, a sliding block 4 is slidably mounted on the No. 1 guide rail 3, a movable plate 5 is fixed on the sliding block 4, and a No. 2 cylinder 21 fixedly connected to the movable plate 5 is also fixed on the fixed plate 2. A sliding assembly connected to the movable plate 5 is provided on the fixed plate 2. The sliding assembly is connected to the support sleeve 12, wherein the sliding assembly includes a plurality of inclined grooves 6 provided on the movable plate 5, a No. 2 guide rail 7 is fixed on the fixed plate 2, and the No. 2 guide rail 7 is provided with a through groove 8 on the side facing the operating table 1, and a plurality of movable blocks 9 equidistantly distributed are slidably installed in the No. 2 guide rail 7, and a limiting rod 10 engaged with the inclined groove 6 is fixed on the end of the movable block 9 away from the operating table 1, and a support rod 11 is fixed on the end of the movable block 9 facing the operating table 1, and the support rod 11 is movably connected to the support sleeve 12.

[0047] It should be noted that there are multiple inclined slots 6, and the spacing between the ports of the inclined slots 6 close to each other at one end is the same, and the spacing between the ports of the inclined slots 6 far away from each other at one end is also the same. In the initial state, the limit rod 10 is located at the end of the stroke at the end where the spacing between the ports of the inclined slots 6 is smaller, so that the spacing between the cutting discs 14 is minimized. If the size of the cardboard needs to be adjusted, the No. 1 cylinder 17 works and controls the separation of the cutting disc 14 from the cardboard. At the same time, under the action of the No. 2 cylinder 21, the movable plate 5 is driven to move, thereby driving the sliding block 4 to move along the length direction of the No. 1 guide rail 3, and the movable plate 5 will also drive the inclined slot 6 moves, and under the action of the inclined slot 6, the limiting rod 10 is controlled to move, thereby driving the movable block 9 to move along the length direction of the No. 2 guide rail 7 and move in the direction away from each other. The movable block 9 will also drive the support rod 11 to move, and drive the support plate 13 to move through the support sleeve 12, so that the cutting disc 14 moves in the direction away from each other. When the adjustment is completed, the No. 1 cylinder 17 stops working, so that the movable plate 5 no longer moves, and ensures that the spacing between the cutting discs 14 no longer changes. At this time, under the action of the No. 1 cylinder 17, the cutting disc 14 is reset, and the cardboard is cut again.

[0048] Preferably, the second guide rail 7 is arranged vertically with the first guide rail 3 to ensure that the limit rod 10 is located in the same horizontal plane, thereby ensuring that when the movable plate 5 moves, under the action of the inclined groove 6, the limit rod 10 makes an equidistant approach or diffusion movement.

[0049] See also Figure 1 、 Figure 4 、 Figure 5 , a cutting knife 25 is arranged on the operating table 1, and a transverse cutting mechanism connected to the cutting knife 25 is provided on the fixed plate 2, and the transverse cutting mechanism can drive the cutting knife 25 to cut the cardboard placed on the conveying plate 22, and convey the cut cardboard to the required position. The transverse cutting mechanism includes a No. 2 motor 23 fixedly mounted on the fixed plate 2, and a No. 1 rotating rod 24 connected to the output shaft of the No. 2 motor 23 is rotatably mounted on the fixed plate 2, and the No. 1 rotating rod 24 is sleeved with a belt 26, and a conveying assembly connected to the belt 26 is provided on the fixed plate 2, and the No. 1 rotating rod 24 is fixedly connected to the cutting knife 25, wherein the conveying assembly includes a No. 2 rotating rod 27 rotatably mounted on the operating table 1 and symmetrically arranged, and a pulley is fixed on the No. 2 rotating rod 27, and a conveyor belt 28 is sleeved on the pulley, and one of the No. 2 rotating rods 27 is connected to the belt 26.

[0050] Furthermore, when the long cardboard is divided into multiple cardboards of equal size, these cardboards need to be cut horizontally so that the cardboard is cut into the required size. The cutting knife 25 is provided with a blade. When the cutting knife 25 rotates, the blade will intermittently abut against the conveying plate 22. When the longitudinal cutting is completed, the cardboard continues to move. At this time, the No. 2 motor 23 works to drive the No. 1 rotating rod 24 to rotate, thereby driving the cutting knife 25 to rotate. The No. 1 rotating rod 24 will also drive the No. 2 rotating rod 27 to rotate through the belt 26, thereby driving the conveyor belt 28 to move through the pulley. When the cardboard moves to contact the cutting knife 25, under the action of the cutting knife 25, the cardboard is cut horizontally at equal intervals. The cardboard will be cut into blocks and enter the conveyor belt 28. Under the action of the conveyor belt 28, the cardboard is continuously transported to the required stacking position.

[0051] Preferably, if the size of the horizontal cutting needs to be adjusted, the power of the second motor 23 can be adjusted to change the speed of the first rotating rod 24, so that the speed of the cutting knife 25 changes, thereby adjusting the cutting size of the cardboard by the cutting knife 25.

[0052] Also includes:

[0053] See also Figures 1-4 、 Figures 8-10 , a cardboard stacking mechanism is provided on the transverse plate 29, and a plurality of receiving plates 34 are equidistantly distributed on the circumference of the cardboard stacking mechanism are provided on the cardboard stacking mechanism, and baffles 35 are fixed on both sides of the receiving plates 34. The cardboard stacking mechanism can control the receiving plates 34 to maintain a horizontal state and drive the receiving plates 34 to do circular motion. The cardboard stacking mechanism includes a rotating sleeve 30 rotatably mounted on the transverse plate 29, a cross plate 31 is fixed on the rotating sleeve 30, and a fixed sleeve 37 mounted on the rotating sleeve 30 is fixed on the transverse plate 29. The transverse plate 29 is provided with a fixed sleeve 37 that is sleeved on the rotating sleeve 30. The sleeve 37 and the cross plate 31 are connected to an angle maintaining assembly, and the angle maintaining assembly is connected to the receiving plate 34, wherein the angle maintaining assembly includes a plurality of receiving rods 32 rotatably mounted on the cross plate 31 and equidistantly distributed around the circumference, the receiving rods 32 are sleeved with a toothed belt 39 connected to the fixed sleeve 37, and a rotating plate 33 is fixed to the receiving rod 32; the angle maintaining assembly also includes a protruding rod fixedly mounted on the rotating plate 33, and the receiving plate 34 is provided with a sliding groove engaged with the protruding rod, and the receiving plate 34 is in contact with the rotating plate 33.

[0054] Furthermore, the baffles 35 are arranged on both sides of the receiving plate 34. The height of the baffle 35 on the side close to the conveyor belt 28 is lower, and the height of the baffle 35 on the side away from the conveyor belt 28 is higher. The cross plate 31 is arranged in a cross shape, and the four ends of the cross plate 31 are respectively installed with a receiving rod 32, and a synchronous wheel is fixedly installed on the receiving rod 32 and the fixed sleeve 37. A toothed belt 39 is sleeved on the synchronous wheel. In the initial state, the receiving plate 34 is completely in contact with the rotating plate 33, and the receiving plate 34 and the rotating plate 33 are in a horizontal state. When it is necessary to receive the cardboard, the rotating sleeve 30 rotates, driving the cross plate 31 to rotate, thereby driving the receiving rod 32 to move. Since the fixed sleeve 37 is fixed, under the action of the synchronous wheel and the toothed belt 39, the receiving rod 32 rotates, and the rotation direction is opposite to the rotation direction of the rotating sleeve 30, and the rotation angle is the same as the angle of the rotating sleeve 30, thereby ensuring the fixed The rotating plate 33 fixed on the receiving rod 32 always remains in a horizontal state, and the rotating plate 33 also drives the receiving plate 34 to move. When the receiving plate 34 moves to the end of the stroke toward the side of the conveyor belt 28, the lower baffle 35 blocks the cardboard on the conveyor belt 28 to ensure that the cardboard on the conveyor belt 28 does not fall off the conveyor belt 28. The rotating plate 33 continues to move, causing the rotating plate 33 to move in the direction away from the conveyor belt 28. Under the action of the guide component, the receiving plate 34 moves along the length direction of the protruding rod, ensuring that the receiving plate 34 moves toward the ground while its position in the horizontal direction does not change. When the baffle 35 is located below the conveyor belt 28, the receiving plate 34 moves to the stacking position, and the cardboard on the conveyor belt 28 moves to the outside of the conveyor belt 28 and into the receiving plate 34. Under the action of the higher baffle 35, it is ensured that the cardboard will not fall off the receiving plate 34.

[0055] Preferably, when the receiving plate 34 completes the palletizing, the receiving plate 34 moves in a direction away from the conveyor belt 28 under the action of the guide assembly. At the same time, the other receiving plate 34 moves toward the direction close to the conveyor belt 28, and under the action of the baffle 35, it is ensured that the cardboard will not separate from the conveyor belt 28 until the other receiving plate 34 moves to the palletizing position, thereby achieving the effect of continuously palletizing the cardboard without stopping the machine.

[0056] See also Figures 1-4 、 Figures 8-10, a guide assembly is arranged on the horizontal plate 29 and is connected to the cardboard stacking mechanism and the receiving plate 34. The guide assembly can be activated when the cardboard stacking mechanism drives the receiving plate 34 to move, and drives the receiving plate 34 to move in the horizontal direction. The guide assembly includes a fixed rod 38 fixedly mounted on the horizontal plate 29 and movably connected to the rotating sleeve 30. A symmetrically arranged guide plate 40 is fixed on the fixed rod 38. The guide plate 40 is hollow. Symmetrically arranged guide rods 36 are fixed on both sides of the receiving plate 34. The guide rods 36 cooperate with the guide plates 40.

[0057] To be specific, the guide plate 40 is hollow, and the size of the hollow is the same as that of the guide rod 36. When the cross plate 31 rotates, it drives the rotating plate 33 and the receiving plate 34 to move. When the receiving plate 34 moves to the minimum distance from the conveyor belt 28, the guide rod 36 fixed on the receiving plate 34 will enter the hollow gap of the guide plate 40 and engage with it. The guide plate 40 can be divided into two parts, the first part is vertically set, and the second part is inclined. At this time, the cross plate 31 continues to move, causing the rotating plate 33 to continue to make a circular motion. Under the action of the guide plate 40 and the guide rod 36, the receiving plate 34 is moved along the length of the guide plate 40. When the cardboard is stacked, the guide rod 36 enters the inclined section of the guide plate 40, causing the receiving plate 34 to move toward the initial position on the rotating plate 33. When the guide rod 36 is separated from the guide plate 40, the receiving plate 34 returns to the initial position on the rotating plate 33. At this time, the guide rod 36 on the next receiving plate 34 just moves into the guide plate 40. At this time, the stacked cardboard can be taken out from the receiving plate 34 and the above steps are repeated, thereby achieving the effect of continuously stacking the cardboard without stopping the machine after the stacking is completed.
