Description

Technical Field

[0001] This invention relates to the field of paperboard processing equipment technology, and in particular to a corrugated paperboard feeding machine. Background Technology

[0002] Currently, in the printing paperboard industry, the manufacturing technology of printing presses and gluing machines is becoming more and more mature, and their operating speed is steadily increasing. At present, the paper feeding of printing presses and gluing machines is usually completed by paperboard feeding machines.

[0003] Existing cardboard feeding machines transfer stacks of cardboard formed by multiple cardboard stacks onto a conveyor belt, allowing individual cardboard pieces to be transported in a fish-scale pattern to equipment such as inspection machines and gluing machines.

[0004] Existing feeding machines lift the cardboard above it from the original stack by inserting a separating plate at the bottom of the cardboard that needs to be separated. However, when pushing cardboard with a large mass, the separating plate of the feeding machine is difficult to lift and separate the stack of multiple extra-large cardboards. Therefore, there is an urgent need for a corrugated cardboard feeding machine to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a corrugated cardboard feeding machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0006] The solution to the technical problem of this invention is:

[0007] A corrugated cardboard feeding machine includes a frame, on which are mounted:

[0008] A lifting and feeding mechanism includes a lifting and conveying component that is movable in the vertical direction on the frame;

[0009] A conveying mechanism is installed downstream of the lifting and feeding mechanism. A conveying surface is formed on the conveying mechanism. The lifting and feeding component can move upward on the frame to be flush with the conveying surface.

[0010] A horizontal paper-pushing mechanism is mounted on the frame. The horizontal paper-pushing mechanism includes a mounting frame, a paper-pushing frame, a paper-pushing plate, and a telescopic drive component. The mounting frame is located above the lifting conveyor and extends horizontally along the direction from the lifting paper-feeding mechanism to the conveying mechanism. The paper-pushing frame can slide on the mounting frame in a direction close to or away from the conveying mechanism. The paper-pushing plate is mounted on the side of the paper-pushing frame facing the conveying mechanism, forming a pushing space on the side facing the conveying mechanism. The paper-pushing plate has perforations. The telescopic drive component has a telescopic drive end. The straight line in which the telescopic drive end moves extends in a direction close to the conveying mechanism and is inclined downwards. The telescopic drive end is equipped with a toothed block, which can move in and out of the pushing space. The side of the toothed block closest to the conveying mechanism is the tooth surface. When the telescopic drive end moves in a direction away from the conveying mechanism and tilts upwards, the mounting frame can move in a direction close to the conveying mechanism.

[0011] The technical solution has at least the following beneficial effects: The stacked paper stack is placed on the lifting conveyor, which moves the paper stack horizontally towards the moving conveyor. Then the lifting conveyor rises until the upper surface of the paper stack is flush with the conveying surface of the conveyor. The paper pusher moves towards the paper stack, and the telescopic drive drives the toothed block to move into the pushing space and inserts the toothed block into the bottom of the paper stack of the preset thickness. Then the telescopic drive drives the toothed block to move away from the conveyor and tilt upward. At the same time, the paper pusher moves horizontally towards the conveyor. At this time, the paper pusher and the toothed block move the same distance in the horizontal direction, so that the toothed block is relatively stationary in the horizontal direction and only moves upward. This allows the toothed block to drive the paper stack of the preset thickness to move upward synchronously, so that the paper stack of the preset thickness is separated from the remaining part of the original paper stack. Then the paper pusher drives the pusher plate to move on the mounting frame until the pusher plate abuts against the separated paper stack. The paper pusher continues to move, so that the pusher plate pushes the paper stack to the conveyor.

[0012] In this application, by inserting toothed blocks and moving a paper stack of a preset thickness upward, the paper stack with a large volume and weight can be separated from the original paper stack. This reduces the need for manual assistance in handling large pieces of cardboard, thereby reducing the workload of workers and improving the automation level of the feeder. Secondly, by setting a telescopic drive component with tilting and telescopic movement, it can cancel out the horizontal movement of the paper pusher. That is, during the process of the paper pusher moving the pusher board to push the paper stack, the paper stack of the preset thickness can rise synchronously, reducing the waiting time for the paper stack to separate from the original paper stack before the pusher board performs the pushing operation, and speeding up the operation of the feeder.

[0013] As a further improvement to the above technical solution, the frame is provided with a guide plate between the lifting paper feeding mechanism and the conveying mechanism. The guide plate can rotate around the horizontal axis. The side of the guide plate away from the rotating connection can rotate to abut against the conveying mechanism or extend in the vertical direction. When the guide plate extends along the vertical mechanism, a paper stack shaping space is formed between the guide plate and the pusher plate.

[0014] Because after the toothed block moves one end of the paper stack upwards, the other end of the top cardboard in the paper stack may protrude outside the paper stack, causing the subsequent paper stack to become scattered on the conveying mechanism. By adopting the above technical solution, when the toothed block moves the paper stack vertically but not horizontally, the guide plate is rotated to a vertical position, and the pusher plate pushes the separated paper stack. At the same time, the lifting conveyor at the bottom moves upwards, pushing the side of the paper stack away from the pusher plate upwards, so that the paper stack is in a horizontal position while the side away from the pusher plate becomes neat, allowing the paper stack to be pushed in a neat stacked posture.

[0015] When the pusher plate moves the paper stack to the conveying mechanism, the guide plate rotates to abut against the conveying mechanism. At this time, the paper stack first abuts against the guide plate and then smoothly enters the conveying mechanism under the action of the inclined guide plate, reducing the jamming of the paper stack between the lifting conveyor and the conveying mechanism.

[0016] As a further improvement to the above technical solution, a paper divider is provided at the bottom of the paper pusher, and the paper divider can move along the horizontal direction of entering and exiting the paper pusher space on the paper pusher.

[0017] By adopting the above technical solution, when the toothed block moves the paper stack upward to separate it from the original paper stack, the paper divider moves into the paper pushing space, thus being located between the separated paper stack and the paper stack, preventing the paper stack that has been grabbed from falling back onto the paper stack, and improving the stability of the paper stack transfer between the lifting conveyor and the conveying mechanism.

[0018] As a further improvement to the above technical solution, the conveying mechanism includes a first conveying component and a second conveying component. The first conveying component is rotatably mounted on the frame, and the rotation axis of the first conveying component is located at one end near the lifting and feeding mechanism. The second conveying component is rotatably mounted on the frame, and the rotation axis of the second conveying component is located at one end near the first conveying component. The height of the rotation axis of the first conveying component is higher than the height of the rotation axis of the second conveying component. The first conveying component can rotate until the height of its conveying end is higher than or equal to the height of the conveying beginning of the second conveying component. A receiving cavity is formed on the second conveying component. The receiving cavity is located below the conveying end of the first conveying component. A fish-scale discharge port is opened on the side of the receiving cavity away from the first conveying component.

[0019] Because there may be a difference between the feeding speed at the lifting conveyor and the discharging speed at the second conveyor assembly, for example, when the speed of the second conveyor assembly of the feeder conveying a complete stack of paper to the next process equipment is greater than the speed of placing the same stack of paper at the lifting conveyor, there may be a situation where the lifting conveyor is still feeding after the discharging is completed at the second conveyor assembly, resulting in the equipment stopping and waiting at the second conveyor assembly, which leads to low production efficiency of the feeder. By adopting the above technical solution, firstly, as many stacks of paper as possible are placed at the lifting conveyor, and then the horizontal paper pushing mechanism divides the stacks of paper at the lifting conveyor into multiple paper piles and conveys them to the first conveyor assembly. The first conveyor assembly then conveys the paper piles to the second conveyor assembly. During this process, the conveying speed at the first conveyor assembly is increased to be greater than the conveying speed at the second conveyor assembly, so that the stacks of paper at the lifting conveyor are transferred to the first conveyor assembly as soon as possible, making it easier for the next stack of paper to enter the empty lifting conveyor.

[0020] When the first conveying component receives too many paper stacks, its conveying end is raised above the conveying beginning of the second conveying component. The paper stacks fall from the conveying end of the first conveying component into the receiving cavity, where they are then transported in a fish-scale pattern through the fish-scale discharge port. While the first conveying component continuously feeds paper stacks into the receiving cavity, it enters an empty state, waiting for the lifting conveyor to place the paper stacks. Meanwhile, the second conveying component can continuously release cardboard from the receiving cavity, reducing downtime at its conveying end. This allows the feeder to operate continuously, improving production efficiency.

[0021] As a further improvement to the above technical solution, the conveying mechanism further includes a aligning component, which is installed at one end of the second conveying component near the first conveying component. The receiving cavity is formed inside the aligning component, and an opening is formed on the side of the receiving cavity facing the first conveying component. The fish scale discharge port is formed on the side of the aligning component away from the first conveying component.

[0022] By adopting the above technical solution, using the aligning component as the receiving cavity, it can not only receive the paper pile falling from the first conveying component, but also align the paper pile falling into the second conveying component to facilitate its discharge from the fish scale discharge port, thereby reducing the use of receiving components and lowering the cost of the equipment.

[0023] As a further improvement to the above technical solution, the conveying end of the first conveying component is provided with a aligning baffle. The aligning baffle can rotate around a horizontal axis perpendicular to the straight line of the conveying direction of the first conveying component. The aligning baffle can rotate to the opening and form an aligning space with the aligning component.

[0024] By adopting the above technical solution, when the first conveying component puts the paper stack into the second conveying component, because the paper stack is a free fall, some cardboard may protrude out of the paper stack on the side away from the aligning component, which may affect its subsequent transmission on the second conveying component. Therefore, when the paper stack falls into the second conveying component, the aligning baffle rotates towards the aligning component until it is located at the opening, and works together with the aligning component to limit the cardboard at this point to the aligning space, so that multiple cardboards in a paper stack are neatly stacked.

[0025] As a further improvement to the above technical solution, the second conveying assembly includes a belt, a first frame and a second frame. The first frame is installed on the frame, and the second frame is slidably installed on the second frame along the length direction of the second conveying assembly. The belt is wound around both the first frame and the second frame.

[0026] By adopting the above technical solution, after the first frame is moved on the second frame, the overall length of the second conveying component can be extended or shortened. Then, in conjunction with the first frame that can rotate on the frame, the position of the conveying end of the second conveying component can be moved arbitrarily, thereby adapting to the feeding end of different equipment and improving the applicability of the corrugated cardboard feeder of this application to different equipment.

[0027] As a further improvement to the above technical solution, the alignment component can slide along the length direction of the second conveying component on the first frame.

[0028] By adopting the above technical solution, the sliding alignment component can change the position of the receiving cavity, so that the receiving cavity can better receive the paper pile falling from the first conveying component.

[0029] As a further improvement to the above technical solution, the frame is provided with a recycling space below the conveying mechanism, and the lifting conveyor can be moved to the input end position of the recycling space.

[0030] By adopting the above technical solution, when only the bottom support frame remains of a paper stack, the lifting conveyor moves to the input end of the recycling space, and then conveys the bottom support frame into the recycling space along the original conveying direction of the lifting conveyor. At the same time, the next paper stack behind it is conveyed into the lifting conveyor, reducing the time consumed by reversing the conveying direction to send the bottom support frame out of the lifting conveyor and improving production efficiency.

[0031] As a further improvement to the above technical solution, the frame is provided with a horizontal push assembly in the recycling space. The horizontal push assembly has a horizontal push drive end, which can move horizontally in the recycling space along the transmission direction of the conveying assembly.

[0032] By adopting the above technical solution, when the bottom support frame enters the recycling space and moves to the lateral drive component, the lateral push drive end pushes the bottom support frame laterally out of the frame, thereby creating a clearance for the first and second conveying components that can rotate above, reducing the obstruction to recycling the bottom support frame.

[0047] Reference Figure 1 , Figure 2 and Figure 3 The corrugated cardboard feeding machine provided in this application includes a frame 1, on which a lifting paper feeding mechanism 2, a horizontal paper pushing mechanism 3, and a conveying mechanism 4 are provided. Multiple cardboards are stacked on the bottom support frame to form a paper stack. The entire paper stack is transported to the lifting paper feeding mechanism 2. Through the lifting paper feeding mechanism 2 and the horizontal paper pushing mechanism, the paper stack formed by the cardboard 36 on the top of the paper stack is transferred to the conveying mechanism 4, so that the multiple cardboards of the paper stack are arranged in a fish scale pattern on the conveying mechanism 4. Then, the paper stack is transported to carton processing equipment such as printing machines, slotting machines, and die-cutting machines to complete the processing of the cardboard.

[0048] The lifting and feeding mechanism 2 includes a lifting conveyor 21, which can move vertically on the frame 1. Specifically, the lifting conveyor 21 includes a lifting conveyor belt. A lifting drive 22 is provided on the frame 1. The two ends of the lifting conveyor belt, which are perpendicular to its own conveying direction, are connected to the lifting drive 22. The lifting drive 22 drives the lifting conveyor belt to slide vertically on the frame 1. The lifting drive 22 includes a gear and rack drive mechanism or a synchronous belt mechanism, etc. This application embodiment does not specifically limit this.

[0049] Furthermore, the lifting and feeding mechanism 2 also includes a paper stack conveyor belt (not shown in the figure). The paper stack conveyor belt is located on the side of the lifting and feeding conveyor belt away from the conveying mechanism 4. The paper stack conveyor belt can arrange multiple paper stacks in sequence. The paper stack conveyor belt can be flush with the lifting and feeding component that moves downward to the bottom of the frame 1. When the paper stack conveyor belt and the lifting and feeding component are flush, the paper stack can be directly transferred to the lifting and feeding component.

[0050] The conveying mechanism 4 is installed downstream of the lifting and feeding mechanism 2. A conveying surface is formed on the conveying mechanism 4. The lifting and feeding component 21 can move upward on the frame 1 to be flush with the conveying surface.

[0051] Reference Figure 4 A horizontal paper-pushing mechanism 3 is mounted on the frame 1. The horizontal paper-pushing mechanism 3 includes a mounting frame 31, a paper-pushing frame 32, a paper-pushing plate 33, and a telescopic drive component 34. The mounting frame 31 is located above the lifting conveyor 21 and extends horizontally along the direction from the lifting paper-feeding mechanism 2 to the conveying mechanism 4. The paper-pushing frame 32 can slide on the mounting frame 31 in a direction close to or away from the conveying mechanism 4. The paper-pushing plate 33 is mounted on the side of the paper-pushing frame 32 facing the conveying mechanism 4, forming a pusher on the side of the paper-pushing frame 32 facing the conveying mechanism 4. The material space has a perforation on the push plate 33. The telescopic drive 34 has a telescopic drive end. The straight line in which the telescopic drive end moves extends along the direction close to the conveying mechanism 4 and is inclined downward. The telescopic drive end is equipped with a toothed block 35. The toothed block 35 can move to pass through the perforation and enter and exit the material space. The side of the toothed block 35 close to the conveying mechanism 4 is a tooth surface. The tooth surface extends in the vertical direction. When the telescopic drive end moves away from the conveying mechanism 4 and is inclined upward, the mounting frame 31 can move towards the direction close to the conveying mechanism 4.

[0052] As described above, the stacked paper stacks are placed on the lifting conveyor 21, which moves the paper stack horizontally towards the moving conveyor 4. Then, the lifting conveyor 21 rises until the upper surface of the paper stack is flush with the conveying surface of the conveyor 4. The paper pusher 32 moves towards the paper stack, and the telescopic drive 34 drives the toothed block 35 to move into the pushing space, inserting it into the bottom of the paper stack of a preset thickness. Then, the telescopic drive drives the toothed block 35 to move away from the conveyor 4 and tilt upwards. Simultaneously, the paper pusher 32 moves towards the conveyor. The mechanism 4 moves horizontally. At this time, the paper pusher 32 and the toothed block 35 move the same distance in the horizontal direction, so that the toothed block 35 is relatively stationary in the horizontal direction and only moves upward. This causes the toothed block 35 to drive the paper stack of the preset thickness to move upward synchronously, so that the paper stack of the preset thickness is separated from the remaining part of the original paper stack. Then the paper pusher 32 drives the pusher plate 33 to move on the mounting frame 31 until the pusher plate 33 abuts against the separated paper stack. The paper pusher 32 continues to move, so that the pusher plate 33 pushes the paper stack to the conveying mechanism 4.

[0053] In this application, by inserting the toothed block 35 and driving the paper stack of the preset thickness to move upward, the paper stack with a large volume and weight can be separated from the original paper stack. This reduces the need for manual assistance in handling large pieces of cardboard, thereby reducing the workload of workers and improving the automation level of the feeder. Secondly, by setting the inclined telescopic drive component 34, it can cancel out the horizontal movement of the paper pusher 32. That is, during the process of the paper pusher 32 driving the pusher plate 33 to move and push the paper stack, the paper stack of the preset thickness can rise synchronously, reducing the waiting time for the paper stack to separate from the original paper stack before the pusher plate 33 performs the pushing operation, and speeding up the operation of the feeder.

[0054] In this embodiment, the telescopic drive component 34 includes a telescopic drive cylinder, which is fixedly installed on the paper pusher 32. The piston rod of the telescopic drive cylinder extends towards the conveying mechanism 4 and is inclined downward. The frame 1 is provided with a slide rail for limiting the movement trajectory of the toothed block 35. The toothed block 35 is slidably installed on the slide rail and connected to the end of the piston rod of the telescopic drive cylinder.

[0055] Specifically, the mounting frame 31 is provided with a horizontal moving drive 311 for driving the paper pusher 32 to move horizontally toward or away from the conveying mechanism 4 on the mounting frame 31. The horizontal moving drive 311 can be a gear chain drive mechanism or a rodless cylinder slider mechanism, and this embodiment does not specifically limit it.

[0056] Reference Figure 5In this embodiment, after the toothed block 35 moves one end of the paper stack upward, the other end of the top cardboard in the paper stack may protrude out of the paper stack, causing the subsequent paper stack to become scattered on the conveying mechanism 4. Therefore, the frame 1 is provided with a guide plate 11 between the lifting paper feeding mechanism 2 and the conveying mechanism 4. The guide plate 11 can rotate around the horizontal axis. The side of the guide plate 11 away from the rotating connection can rotate to abut against the conveying mechanism 4 or extend in the vertical direction. When the guide plate 11 extends along the vertical mechanism, a paper stack shaping space is formed between the guide plate 11, the lifting conveyor 21 and the pusher plate 33.

[0057] As can be seen from the above, when the toothed block 35 causes the paper stack to move vertically but not horizontally, the guide plate 11 is rotated to a vertical position, and the pusher plate 33 pushes the separated paper stack. At the same time, the lifting conveyor 21 at the bottom moves upward, pushing the side of the paper stack away from the pusher plate 33 upward, so that the paper stack is in a horizontal position and the side away from the pusher plate 33 becomes neat, so that the paper stack can be pushed in a neat stacked posture. When the pusher plate 33 pushes the paper stack to the conveying mechanism 4, the guide plate 11 rotates to abut against the conveying mechanism 4. At this time, the paper stack first abuts against the guide plate 11, and under the action of the inclined guide plate 11, it smoothly enters the conveying mechanism 4, reducing the jamming of the paper stack between the lifting conveyor 21 and the conveying mechanism 4.

[0058] Specifically, one end of the guide plate 11 is rotatably mounted on the frame 1, and the other end is a free end. A guide plate rotary cylinder 12 is rotatably mounted on the frame 1. The guide plate rotary cylinder 12 is rotatably connected to the middle of the side of the guide plate 11 near the conveying assembly. When the piston rod of the guide plate rotary cylinder 12 extends or retracts, it drives the guide plate 11 to rotate.

[0059] Furthermore, both ends of the guide plate 11 are provided with guide arc surfaces, which improve the smoothness of the paper stack moving on the guide plate 11.

[0060] As a further embodiment, a separating plate 36 is provided at the bottom of the paper pusher 32. The separating plate 36 can move along the horizontal direction of entering and exiting the paper pusher space on the paper pusher 32. When the toothed block 35 drives the paper stack upward to separate from the original paper stack, the separating plate 36 moves into the paper pusher space, thereby being located between the separated paper stack and the paper stack, preventing the paper stack that has been grabbed from falling back onto the paper stack, and improving the stability of the paper stack transferring between the lifting conveyor 21 and the conveying mechanism 4.

[0061] Specifically, a paper-splitting push cylinder 361 is provided on the paper pusher 32, and a paper-splitting moving slide rail is provided on the paper pusher 32. The paper-splitting sheet 36 is slidably installed on the paper-splitting moving slide rail, and the piston rod of the paper-splitting push cylinder 361 is connected to the paper-splitting sheet 36.

[0062] Because the feeding speed of the feeder at the lifting conveyor 21 and the discharging speed at the second conveyor assembly 42 may differ—for example, if the speed at which the second conveyor assembly 42 of the feeder transports a complete stack of paper to the next process equipment is greater than the speed at which it places the same stack of paper at the lifting conveyor 21—it is possible that after the second conveyor assembly 42 has finished discharging, the lifting conveyor 21 is still in the feeding process, causing the equipment to stop and wait at the second conveyor assembly 42, resulting in low production efficiency of the feeder. Therefore, in this embodiment, referring to… Figure 3 and Figure 6 The conveying mechanism 4 includes a first conveying component 41 and a second conveying component 42. The first conveying component 41 is rotatably mounted on the frame 1, and the axis of rotation of the first conveying component 41 is located at one end near the lifting and feeding mechanism 2. The second conveying component 42 is rotatably mounted on the frame 1, and the axis of rotation of the second conveying component 42 is located at one end near the first conveying component 41. The height of the axis of rotation of the first conveying component 41 is higher than the height of the axis of rotation of the second conveying component 42. The first conveying component 41 can rotate until the height of its conveying end is higher than or equal to the height of the conveying beginning of the second conveying component 42. A receiving cavity 431 is formed on the second conveying component 42. The receiving cavity 431 is located below the conveying end of the first conveying component 41. A fish-scale discharge port is opened on the side of the receiving cavity 431 away from the first conveying component 41. The first conveying component 41 can rotate until the conveying surfaces of the second conveying component 42 are parallel to each other.

[0063] In this embodiment, both the first conveying component 41 and the second conveying component 42 are conveyor belts.

[0064] As can be seen from the above, firstly, as many paper stacks as possible are placed at the lifting conveyor 21. Then, the horizontal paper pushing mechanism 3 divides the paper stacks at the lifting conveyor 21 into multiple paper piles and transports them to the first conveying component 41. The first conveying component 41 then transports the paper piles to the second conveying component 42. During this process, the transport speed at the first conveying component 41 is increased to be greater than the transport speed at the second conveying component 42, so that the paper stacks at the lifting conveyor 21 can be transferred to the first conveying component 41 as soon as possible, making it easier for the next paper stack to enter the empty lifting conveyor 21.

[0065] When the first conveying component 41 receives too many paper stacks, the conveying end of the first conveying component 41 is raised above the conveying beginning of the second conveying component 42. The paper stacks fall from the conveying end of the first conveying component 41 into the receiving cavity 431, and are then transported in a fish-scale arrangement through the fish-scale discharge port of the receiving cavity 431. After the first conveying component 41 continuously feeds paper stacks into the receiving cavity 431, when the first conveying component 41 enters an empty state waiting for the lifting conveyor 21 to place the paper stacks, the second conveying component 42 can always receive paper stacks from the receiving cavity 431. The continuous release of cardboard in 31 reduces the occurrence of downtime at the end of the second conveying component 42, enabling the feeder to operate continuously and improving production efficiency. Moreover, the rotatable second conveying component 42, which has a height difference from the first conveying component 41, can rotate to tilt its conveying end downwards. When the paper stack enters the tilted second conveying component 42, the tilted bearing cavity can prevent the paper stack from falling towards the first conveying component 41 after free fall, so that the paper stack can fall stably onto the second conveying component 42.

[0066] Furthermore, as the paper stack gradually accumulates in the receiving cavity 431 of the second conveying component 42, the total height of the paper stack gradually increases, gradually raising the conveying end of the first conveying component 41 until the conveying surface of the first conveying component 41 is flush with the horizontal plane. Through this design, the first conveying component 41 gradually adapts to the continuously stacked paper stack, reducing the impact of the first conveying component 41 on the increasing paper stack.

[0067] Specifically, the frame 1 is equipped with a first conveying component rotary cylinder 411 and a second conveying component rotary cylinder 421. Both the first conveying component rotary cylinder 411 and the second conveying component rotary cylinder 421 are rotatably mounted on the frame 1. The piston rod of the first conveying component rotary cylinder 411 is rotatably connected to the end of the first conveying component 41 away from its rotatable connection with the frame 1. The piston rod of the second conveying component rotary cylinder 421 is rotatably connected to the end of the second conveying component 42 away from its rotatable connection with the frame 1. The first conveying component rotary cylinder 411 and the second conveying component rotary cylinder 421 can stably drive the first conveying component 41 and the second conveying component 42 to rotate on the frame 1.

[0068] As a further embodiment, the conveying mechanism 4 also includes a sizing component 43, which is installed at one end of the second conveying component 42 near the first conveying component 41. A receiving cavity 431 is formed inside the sizing component 43, and an opening is formed on the side of the receiving cavity 431 facing the first conveying component 41. A fish scale discharge port is formed between the side of the sizing component 43 away from the first conveying component 41 and the conveying surface of the second conveying component 42.

[0069] Specifically, the aligning assembly 43 includes an aligning frame, a front aligning plate, and side aligning plates. The aligning frame is installed on the second conveying assembly 42. The aligning frame has a front aligning plate on the side closest to the first conveying assembly 41. The aligning frame has side aligning plates on both sides that are horizontal and perpendicular to the conveying direction of the second conveying assembly 42. A receiving cavity 431 with one side open is formed between the front aligning plate and the two side aligning plates.

[0070] As can be seen from the above, by using the aligning component 43 as the receiving cavity 431, it can not only receive the paper pile falling from the first conveying component 41, but also align the paper pile falling into the second conveying component 42 to facilitate its discharge from the fish scale discharge port, thereby reducing the use of receiving components and lowering the cost of the equipment.

[0071] As a further implementation method, refer to Figure 7 The first conveying component 41 is provided with a aligning baffle 44 at its conveying end. The aligning baffle 44 can rotate around a horizontal axis perpendicular to the conveying direction of the first conveying component 41. The aligning baffle 44 can rotate to the opening and together with the receiving part of the aligning component 43, form an aligning space.

[0072] As can be seen from the above, when the first conveying component 41 puts the paper stack into the second conveying component 42, because the paper stack is in free fall, some cardboard 36 may protrude out of the paper stack on the side away from the aligning component 43, which may affect its subsequent transmission on the second conveying component 42. Therefore, when the paper stack falls into the second conveying component 42, the aligning baffle 44 rotates towards the aligning component 43 until it is located at the opening, and works together with the aligning component 43 to limit the cardboard at this location inside the aligning space, so that multiple cardboards in a paper stack are neatly stacked.

[0073] In this embodiment, a aligning rotary drive cylinder is rotatably mounted on the first conveying assembly 41, and the piston rod of the aligning rotary drive cylinder is rotatably connected to the aligning baffle 44.

[0074] As a further embodiment, the second conveying assembly 42 includes a belt, a first frame 422 and a second frame 423. The first frame 422 is mounted on the frame 1, and the second frame 423 is slidably mounted on the second frame 423 along the length direction of the second conveying assembly 42. The belt is wound around both the first frame 422 and the second frame 423.

[0075] As can be seen from the above, after the first frame 422 is moved on the second frame 423, the overall length of the second conveying component 42 can be extended or shortened. Then, in conjunction with the first frame 422 which can rotate on the frame 1, the position of the conveying end of the second conveying component 42 can be moved arbitrarily, thereby adapting to the feeding end of different equipment and improving the applicability of the corrugated cardboard feeder of this application to different equipment.

[0076] As a further implementation, the alignment component 43 can slide along the length of the second conveying component 42 on the first frame 422. The sliding alignment component 43 changes the position of the receiving cavity 431, so that the receiving cavity 431 can better receive the paper pile falling from the first conveying component 41.

[0077] Specifically, a aligning drive is provided on the outside of the first frame 422 to drive the aligning frame to move on the first frame 422. In this embodiment, the aligning drive includes a gear and rack drive structure.

[0078] As a further implementation, the frame 1 is provided with a recycling space 5 below the conveying mechanism 4. The lifting conveyor 21 can move to the input end of the recycling space 5. When only the bottom support frame remains of a paper stack, the lifting conveyor 21 moves to the input end of the recycling space 5 and then conveys the bottom support frame into the recycling space 5 along the original conveying direction of the lifting conveyor 21. At the same time, the next paper stack is conveyed into the lifting conveyor 21, reducing the time consumed by reversing the conveying direction to send the bottom support frame out of the lifting conveyor 21 and improving production efficiency.

[0079] Specifically, a baffle plate 51 is provided between the frame 1 and the recycling space 5 and the lifting and feeding mechanism 2. The baffle plate 51 can rotate on the frame 1. When the baffle plate 51 rotates to move in the vertical direction, it prevents the paper stack from being moved from the lifting and conveying component 21 to the recycling space 5. After the lifting and conveying component 21 has finished transporting the cardboard on the paper stack, leaving only the bottom support frame, the lifting and conveying component 21 moves downward to the input end of the recycling space 5. Then the baffle plate 51 rotates and opens, and the lifting and conveying component 21 is activated to transport the support frame into the recycling space 5. The frame 1 is provided with a recycling conveyor belt in the recycling space 5. After the support frame enters the recycling space 5, it is transported by the recycling conveyor belt to the side of the recycling space 5 away from the lifting and feeding mechanism, reserving space for the next support frame to enter.

[0080] Furthermore, the frame 1 is provided with a horizontal push assembly 52 in the recycling space 5. The horizontal push assembly 52 has a horizontal push drive end, which can move horizontally perpendicular to the transmission direction of the conveying assembly in the recycling space 5. When the bottom support enters the recycling space 5 and moves to the horizontal drive, the horizontal push drive end pushes the bottom support out of the frame 1 laterally, thereby creating a clearance for the first conveying assembly 41 and the second conveying assembly 42 that can rotate above, reducing the obstruction to the recycling of the bottom support.

[0081] Specifically, the horizontal push assembly 52 includes a pusher and a horizontal push drive. The horizontal push drive is used to drive the pusher to move horizontally and perpendicularly to the conveying mechanism 4 within the recovery space 5. In this embodiment, the horizontal push drive includes a gear and rack drive structure, and the pusher moves under the push of the horizontal push drive.

[0082] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
