Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard production technology, specifically to a stacking and conveying device for a corrugated cardboard production line. Background Technology

[0002] Corrugated cardboard is a multi-layered bonded structure, consisting of at least one corrugated core layer and one cardboard layer. It possesses high mechanical strength, capable of withstanding impacts and drops during handling. In the corrugated cardboard production process, a stacking and conveying device is installed at the end of the production line for stacking and transporting the cardboard. Existing stacking and conveying devices mainly consist of a conveyor belt, a stacking mechanism, and a conveyor cart. When the conveyor cart stops within the stacking mechanism and the hydraulic plate on the cart is adjusted to the appropriate position, the conveyor belt moves the corrugated cardboard above the stacking mechanism. The thrust of the conveyor belt causes the corrugated cardboard to fall onto the top of the hydraulic plate. Then, pushers on the stacking mechanism apply force from three directions to the corrugated cardboard, ensuring the stacked cardboard is neatly arranged. Simultaneously, the hydraulic plate descends as the number of cardboard sheets increases until it reaches a set position, at which point the conveyor belt stops transporting the cardboard, and the conveyor cart transfers the cardboard to the next process step.

[0003] However, the stacking and conveying device still has some defects in use: First, if the cardboard is placed at an angle after falling, the pusher plate will first contact the corner of the cardboard when moving. Then, the corner of the cardboard is the first point of force to push the cardboard to rotate and straighten it, so that the corner of the corrugated cardboard is aligned with the corner of the lower cardboard. However, in this process, since the corner of the cardboard is the main point of force and its action time is long, and there is no other force to push the cardboard to rotate except the pusher plate, the corner of the cardboard is easily damaged and wrinkles and other damages occur, affecting the production quality of the cardboard. In addition, when the two pusher plates push the corrugated cardboard, the reciprocating action of the pusher plates causes multiple relative actions on both sides of the cardboard, resulting in repeated force on the cardboard and bulging towards the middle, resulting in an uneven cardboard surface, which affects the subsequent processing of the cardboard. Summary of the Invention

[0004] In view of the shortcomings of existing stacking and conveying devices mentioned in the background art, the present invention provides a stacking and conveying device for corrugated cardboard production lines, which has the advantages of effectively providing rotational suction to make the cardboard rotate and straighten, reducing damage to the corners of the cardboard, and effectively applying pressure to the surface of the cardboard to improve the flatness of the cardboard, thus solving the technical problems mentioned in the background art.

A pad membrane is fixedly connected to the side of the movable plate near the conveyor belt. One end of the movable cavity is fixedly connected to one end of the movable membrane, and the other end of the movable membrane is fixedly connected to the movable block. The movable membrane and the movable block are connected by a compression spring, and the movable membrane and the pad membrane are connected by an air pipe.

[0008] Preferably, movable blocks are movably sleeved on both sides of the main cavity, one end of each movable block is fixedly connected to a movable rod, a compression spring is fixedly connected between the two movable rods, an expanding member is fixedly sleeved inside the main air hole and connected to the movable rod, a pressing rod is movably connected to the inner wall of the fixing member near the air inlet valve and connected to the fixing member by a tension spring, and an expanding member is fixedly connected inside the side air hole and connected to the pressing rod.

[0009] Preferably, the expanding component comprises an expanding membrane, an expanding rod, and an expanding rope. The expanding membrane is made of rubber and is fixedly connected to the diameter of the main vent or side vent. One end of the expanding rod is hinged to one side of the expanding membrane, and the other end of the expanding rod is fixedly connected to the expanding membrane. The two expanding rods are connected by a rubber membrane, and the expanding membrane and the expanding rod are connected by a compression spring. The outer side of the expanding rod is connected to one end of the expanding rope, and the other end of the expanding rope is connected to a moving rod or a pressing rod.

[0010] Preferably, the rotating components are spirally distributed on the surface of the rotating rod, and the spiral directions of the rotating components at both ends of the rotating rod are opposite. The rotating components are composed of a rotating shell and a rotating block. The rotating block is movably sleeved with the rotating shell, and the rotating block and the rotating shell are connected by a compression spring. The rotating block has N-type magnetism.

[0011] Preferably, both the intake valve and the exhaust valve are one-way valves, and the airflow direction of the intake valve is from the outside to the inside of the fixed part, while the airflow direction of the exhaust valve is from the inside of the fixed part to the outside.

[0012] Preferably, the side film and the extrusion film are made of rubber material and filled with gas. The position of the extrusion film corresponds to that of a portion of the rotating component. The number of extrusion films at both ends of the rotating rod is the same, and the positions of the extrusion films at both ends correspond. The number of extrusion blocks is twice the number of extrusion films.

[0013] Preferably, the inner rod has an L-shaped cross-section, the inner membrane, the pad membrane, and the movable membrane are made of rubber material, the pad membrane is filled with gas, the movable block has an S-shaped magnetism, and the moving block is made of iron material.

[0014] The present invention has the following beneficial effects:

[0015] 1. This invention features a rotating rod movably mounted inside a side push plate, with a fixing component and its parts mounted on the front side of the rotating rod. Movable plates are movably mounted on both sides of the main push plate, with movable blocks inside the movable plates. When the main push plate moves along the side push plate, the magnetic attraction of the movable blocks on the rotating component causes the rotating rod to rotate, resulting in the rotating component reciprocatingly pushing the extrusion plate and extrusion block. This effectively changes the internal space of the fixing component, enabling the side push plate to exert a suction force on the cardboard through the side air holes. In other words, the two opposing side push plates push the two opposing sides of the cardboard, effectively enhancing the rotation effect of the cardboard, reducing damage to the cardboard end corners by the side push plates, and improving the quality of cardboard production.

[0016] 2. This invention features an inner rod and inner membrane inside the main push plate, with the movable plate fixedly connected to the inner rod. When the two side push plates move relative to each other, the side push plates push the movable plate into the main push plate, effectively expanding the space inside the inner membrane. This allows the air holes of the main push plate to exert a suction force on the cardboard. Since the suction force generated by the main push plate is less than that of the side push plates, it does not affect the rotation effect of the side push plates on the cardboard, and effectively promotes the flatness of the cardboard edge opposite to the main push plate, preventing the cardboard from warping due to the pushing force of the main push plate and avoiding affecting the subsequent processing and use of the cardboard.

[0017] 3. This invention provides a compression film on the rear side of the rotating rod and a side rod and side film inside the side push plate above the side air hole. The rotation of the rotating rod effectively causes the rotating parts to reciprocate and compress the compression film. Since the spiral directions of the rotating parts at both ends of the rotating rod are opposite, the two side films produce different deformation effects, that is, when one side film expands, the other side film contracts. This effectively causes the side rod to swing, realizing the flattening operation of the side rod on the surface of the cardboard and improving the overall flatness of the corrugated cardboard.

[0018] 4. This invention incorporates a hole-expanding component inside the main air hole and side air hole, a moving block and its components inside the main push plate, a pressing rod inside the fixing component, and a rotating component that is movably connected to the rotating shell and rotating block. A pad is placed on the front side of the moving plate. When the moving plate contracts inward, the pad is compressed, transferring air from it to the moving plate, effectively pushing the moving block outward. This reduces the magnetic force between the moving block and the moving block, and increases the magnetic force between the moving block and the rotating block. This change in magnetic force effectively loosens the hole-expanding rope and causes the hole-expanding rod to rotate towards the hole-expanding membrane, thereby increasing the diameter of the main air hole and side air hole. As the main push plate and side push plate approach the cardboard, this effectively prevents the cardboard's adsorption area from shrinking, thus avoiding irregular wrinkles at the edges due to varying adsorption forces, further ensuring the overall flatness of the cardboard edges.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1:

[0034] Please see Figures 1-2A stacking and conveying device for a corrugated cardboard production line includes a stacking mechanism 1, a conveyor 11 placed below the stacking mechanism 1, a hydraulic component fixedly connected to the top of the conveyor 11, and a hydraulic plate fixedly connected to the top of the hydraulic component. The hydraulic component controls the lifting and lowering of the hydraulic plate, and the height of the hydraulic plate decreases as the number of corrugated cardboard pieces on the top of the hydraulic plate increases, effectively improving the accuracy and safety of the corrugated cardboard falling and being placed. After the corrugated cardboard is stacked, the conveyor 11 starts and transports the corrugated cardboard. A conveyor belt 12 is set above one side of the stacking mechanism 1. The start of the conveyor belt 12 effectively transports the corrugated cardboard to the upper position of the stacking mechanism 1, and then the cardboard falls to the top of the hydraulic plate inside the stacking mechanism 1 by its pushing force and its own gravity.

[0035] Please see Figures 1-3 , Figure 5 Furthermore, a pneumatic component 10 is fixedly installed on the wall of the stacking mechanism 1, which is not on the same side as the conveyor belt 12. The pneumatic component 10 opposite to the conveyor belt 12 passes through the stacking mechanism 1 and is fixedly connected to the main push plate 2. The pneumatic component 10 adjacent to the conveyor belt 12 passes through the stacking mechanism 1 and is fixedly connected to the side push plate 3. The two ends of the main push plate 2 are movably sleeved with the movable plate 21. The movable plate 21 has a movable cavity inside, and the movable plate 21 is movably sleeved with the movable block 23 with S-shaped magnetism through the movable cavity. The movable block 23 effectively generates a magnetic force on the rotating component 61 and the moving block 4, and the three will produce different functional effects.

[0036] Please see Figures 1-2 , Figures 6-8Furthermore, the inner wall of the side push plate 3 is movably connected to both ends of the rotating rod 6. A rotating component 61 is fixedly connected to the surface of the rotating rod 6. The rotating components 61 are spirally distributed on the surface of the rotating rod 6, and the spiral directions of the rotating components 61 at both ends of the rotating rod 6 are opposite. This allows the two rotating components 61 at corresponding positions to rotate in opposite directions when the rotating rod 6 rotates, thus causing one of the extrusion films 321 to be in a state of being extruded while the other is not, thereby causing one side film 32 to expand and the other side film 32 to contract, thus realizing the swinging of the side rod 31. A fixing component 7 is fixedly connected to one side of the inner wall of the side push plate 3 near the main push plate 2. A side air hole is opened on the wall surface of the side push plate 3, and the side air hole communicates with the interior of the fixing component 7. An air inlet valve 71 is fixedly connected to the inner wall of the fixing component 7 located at the side air hole position. An outlet valve 71 is fixedly sleeved at the bottom end of the fixing component 7 corresponding to the position of the air inlet valve 71. Air valve 72, and air outlet valve 72 is connected to side push plate 3. In summary, both air inlet valve 71 and air outlet valve 72 are one-way air valves. The airflow direction of air inlet valve 71 is from the outside to the inside of fixed member 7, and the airflow direction of air outlet valve 72 is from the inside of fixed member 7 to the outside. This ensures that the side air hole can only take in air, effectively ensuring the suction effect of side push plate 3 on cardboard. An extrusion plate 8 is movably sleeved inside fixed member 7. An extrusion block 81 is fixedly connected to one side of extrusion plate 8. The extrusion block 81 passes through the wall of fixed member 7 and contacts rotating member 61. The number of extrusion blocks 81 is twice the number of extrusion film 321. It can effectively push the extrusion block 81 back and forth when rotating member 61 rotates, thereby causing extrusion plate 8 to move and change the air pressure inside fixed member 7, realizing the suction effect of side push plate 3 on cardboard. Extrusion plate 8 and fixed member 7 are connected by compression spring.

[0037] Example 2:

[0038] Please see Figures 1-2 , Figure 6 , Figures 8-9 Furthermore, a compression film 321 is fixedly connected inside the side push plate 3 on the other side of the rotating rod 6. The compression film 321 corresponds to the position of part of the rotating component 61. The number of compression films 321 at both ends of the rotating rod 6 is the same, and the positions of the compression films 321 at both ends correspond. When one compression film 321 is squeezed by the rotating component 61, the opposite compression film 321 will not be squeezed. Therefore, one side film 32 expands and the other side film 32 contracts. The side push plate 3 above the side air hole has a groove, and a side rod 31 is hinged in the middle of the groove. Side films 32 are fixedly connected to the walls of the side push plate 3 on both sides of the side rod 31. The side films 32 are connected to the corresponding compression films 321 below. The side rod 31 is reciprocated by the action of the side film 32, and the side rod 31 flattens the top of the cardboard, effectively improving the overall flatness of the cardboard. The side films 32 and the compression films 321 are made of rubber material and are filled with gas.

[0039] Example 3:

[0040] Please see Figures 1-5 Furthermore, one end of the movable plate 21 located inside the main push plate 2 is fixedly connected to an inner rod 20 with an L-shaped cross-section. This allows the space between the two inner rods 20 to expand when the two movable plates 21 move inward, changing the air pressure inside the inner membrane 201. The inner membrane 201 is fixedly sleeved between the two inner rods 20, and compression springs are fixedly connected to both ends of the inner membrane 201. One side of the main push plate 2 has a main air hole, a main cavity, and a main hole. The main air hole communicates with the main cavity, the main cavity communicates with the main hole, and the main hole communicates with the inner membrane 201. The main air hole can draw air from the cardboard position into the inner membrane 201, causing the main push plate 2 to exert a suction force on the edge of the cardboard, thereby preventing the edge of the cardboard from lifting when the main push plate 2 pushes the cardboard to the other side. A pad 22 is fixedly connected to one side of the moving plate 21. One end of the moving cavity is fixedly connected to one end of the moving membrane 231, and the other end of the moving membrane 231 is fixedly connected to the moving block 23. The moving membrane 231 and the moving block 23 are connected by a compression spring. The moving membrane 231 and the pad 22 are connected by an air pipe. The pad 22 effectively compensates for the different effects on the edge of the cardboard due to the narrowness of the moving plate 21, effectively ensuring that the pushing force on the edge of the cardboard is the same. It also causes the moving block 23 to change its displacement, providing conditions for the subsequent hole-expanding component. In summary, the inner membrane 201, the pad 22, and the moving membrane 231 are made of rubber material, and the pad 22 is filled with gas, which can effectively compensate for the insufficient width of the moving plate 21 and ensure that the pad 22 is flush with the surface of the main push plate 2.

[0041] Example 4:

[0042] Please see Figures 3-4 Furthermore, movable blocks 4 made of iron are movably sleeved on both sides of the main cavity. When the distance between the movable block 23 and the movable block 4 is increased, the magnetic attraction between them weakens. The tension of the compression spring between the two movable rods 41 causes the movable rods 41 to move towards the center, thereby relaxing the hole-expanding rope 52. One end of the movable block 4 is fixedly connected to the movable rod 41. A compression spring is fixedly connected between the two movable rods 41. A hole-expanding component is fixedly sleeved inside the main air hole, and the hole-expanding component is connected to the movable rod 41.

[0043] Please see Figures 10-11 Furthermore, a pressing rod 9 is movably connected to the inner wall of the fixing member 7 near the intake valve 71, and the pressing rod 9 is connected to the fixing member 7 by a tension spring. An expanding member is fixedly connected inside the side air hole, and the expanding member is connected to the pressing rod 9.

[0044] Please see Figure 4 , Figure 11Furthermore, the expanding component consists of an expanding membrane 5, an expanding rod 51, and an expanding rope 52. The expanding membrane 5 is made of rubber and is fixedly connected to the aperture of the main air hole or the side air hole. One end of the expanding rod 51 is hinged to one side of the expanding membrane 5, and the other end of the expanding rod 51 is fixedly connected to the expanding membrane 5. The two expanding rods 51 are connected by a rubber membrane, and the expanding membrane 5 and the expanding rod 51 are connected by a compression spring. The outer side of the expanding rod 51 is connected to one end of the expanding rope 52, and the other end of the expanding rope 52 is connected to the moving rod 41 or the pressing rod 9. By moving the moving rod 41 and the pressing rod 9, the expanding rope 52 changes from its original tensile state to a relaxed state. Then, under the tension of the compression spring, the expanding rod 51 rotates towards the expanding membrane 5, thereby expanding the aperture and ensuring that the main air hole and the side air hole can still adhere to the edge of the cardboard when they are in close contact with the cardboard.

[0045] Please see Figure 12 Furthermore, the rotating component 61 is composed of a rotating shell 611 and a rotating block 612, and the rotating block 612 has N-type magnetism. The rotating block 612 is movably sleeved with the rotating shell 611, and the rotating block 612 and the rotating shell 611 are connected by a compression spring. When the movable block 23 moves in the direction of the rotating rod 6, the distance between the movable block 23 and the rotating component 61 decreases, the magnetic force increases, and the rotating block 612 is effectively moved outward, thereby making the rotating block 612 push the extrusion plate 8 to move inward a greater distance. The movement of the extrusion plate 8 drives the extrusion rod 9 to move. The movement of the extrusion rod 9 in the direction of the side air hole reduces the tension of the expanding rope 52, thereby enlarging the diameter of the side air hole.

[0046] The working principle of the method of using this invention is as follows:

[0047] Adjust the hydraulic plate on the conveyor 11 to a suitable height, start the conveyor belt 12 to move the corrugated cardboard towards the stacking mechanism 1 under the drive of the conveyor belt 12, and drop it into the stacking mechanism 1 and onto the top of the hydraulic plate. At this time, the pneumatic component 10 drives the main push plate 2 and the side push plate 3 to push the cardboard from three directions. Since the movable plate 21 moves along the surface of the side push plate 3, and the movable block 23 has a magnetic attraction to the rotating component 61, the rotating components 61 at different positions on the rotating rod 6 rotate towards the movable block 23, thus realizing the rotation of the rotating rod 6. This causes the rotating component 61 to intermittently push the extrusion plate 8 and the extrusion block 81, causing the extrusion plate 8 to reciprocate and change the space inside the fixed component 7, so that the air pressure inside the fixed component 7 changes continuously. Thus, the air pressure inside the fixed component 7 is controlled by the air inlet valve 71 and the... The fixing component 7 continuously replenishes and releases air, that is, the side air holes of the side push plate 3 generate suction force on the cardboard, effectively causing the two side push plates 3 to generate suction force on the opposite edges of the cardboard, which is conducive to the rotation and alignment of the cardboard, making it easy for the side push plates 3 to align the corrugated cardboard with the lower layer cardboard, while also effectively reducing damage to the end corners of the cardboard and improving the processing quality of the cardboard. In addition, the rotation of the rotating rod 6 also causes the rotating component 61 to exert a squeezing effect on the extrusion film 321. At the same time, the extrusion film 321 at one end of the rotating rod 6 is in a squeezed state, while the extrusion film 321 at the other end of the rotating rod 6 is in a non-squeezed state, thereby causing the corresponding side film 32 to be in the opposite state, thus realizing that the two side films 32 push the side push plate 3 to swing back and forth, effectively performing a flattening operation on the surface of the cardboard and improving the overall flatness of the cardboard.

[0048] At the same time, the movement of the two side push plates 3 pushes the movable plate 21 to retract into the main push plate 2, which increases the overlap of the two inner rods 20 and expands the space volume of the inner membrane 201. The internal air pressure changes, thereby causing the main air hole of the main push plate 2 to generate a suction force on the edge of the cardboard. Since the way the main push plate 2 generates suction is different from that of the side push plates 3, the suction force of the main push plate 2 is smaller than that of the side push plates 3. Therefore, the main push plate 2 will not affect the side push plates 3's operation of straightening the cardboard. At the same time, the main push plate 2 needs to push the cardboard until the cardboard is in contact with the inner wall of the stacking mechanism 1. During this process, the suction force of the main air hole effectively adsorbs both the upper and lower layers of the cardboard, keeping the edge of the cardboard flat and effectively preventing the pushing force of the main push plate 2 from causing the edge of the cardboard to curl up and affecting the subsequent processing of the cardboard.

[0049] As the main push plate 2 and the side push plate 3 approach each other, the gas inside the pad membrane 22 is squeezed by the main push plate 2 and discharged into the movable membrane 231, causing the movable block 23 to move. This results in the movable block 23 moving closer to the rotating component 61 and further away from the moving block 4. At this time, the shortening of the distance between the rotating block 612 and the movable block 23 increases the magnetic attraction between them, further driving the rotating block 612 to move outward. This increases the distance that the rotating block 612 pushes the extrusion block 81 to move. When the extrusion plate 8 can push the extrusion rod 9 to move, the extrusion rod 9 effectively relaxes the expanding rope 52, allowing the expanding rod 51 to move further. Moving towards the expanding membrane 5 increases the diameter of the side air holes. In addition, the increased distance between the moving block 4 and the movable block 23 causes the magnetic attraction between them to disappear. This further causes the two moving rods 41 to move relative to each other due to the tension of the compression spring. At this time, the moving rods 41 effectively relax the expanding rope 52, thereby increasing the diameter of the main air holes. Thus, this device can adjust the hole size in a timely manner according to the distance between the main push plate 2 and the side push plate 3 and the cardboard, effectively preventing the cardboard from shrinking due to the different suction forces and causing irregular wrinkles at the edges, thus further ensuring the overall flatness of the cardboard edges.
