Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paperboard processing equipment, and particularly relates to a corrugated paperboard feeding machine. BACKGROUND

[0002] At present, in the printing paperboard industry, the manufacturing technology of printing machines and box pasting machines is increasingly mature, and the running speed is steadily improved. At present, the paper feeding of the printing machine and the box pasting machine is usually completed by using a paperboard feeding machine. The existing paperboard feeding machine transfers the paper stack formed by stacking multiple paperboards to the conveying belt, so that the single paperboard can be transported by the conveying belt to the inspection machine, the box pasting machine and other equipment in the form of fish scales.

[0003] The existing feeding machine inserts a separation plate at the bottom of the paperboard to be separated, and then lifts the paperboard above to separate from the original paper stack. However, when pushing the paperboard with large mass, it is difficult for the separation plate of the feeding machine to lift and separate the paper stack formed by stacking multiple oversized paperboards from the paper stack, and therefore, there is an urgent need for a corrugated paperboard feeding machine to solve the above problems. SUMMARY

[0004] The present application aims to provide a corrugated paperboard feeding machine to solve one or more technical problems in the prior art, and at least provide a beneficial choice or create conditions.

[0005] The solution to the technical problem of the present application is: A corrugated paperboard feeding machine, comprising a rack, wherein the rack is provided with: a lifting paper feeding mechanism, comprising a lifting conveying part, which can move in the upward and downward directions on the rack; a conveying mechanism installed downstream of the conveying of the lifting paper feeding mechanism, wherein a conveying surface is formed on the conveying mechanism, and the lifting conveying part can move upwards on the rack to be flush with the conveying surface; A horizontal paper pushing mechanism is installed on the frame, which comprises a mounting frame, a paper pushing frame, a paper pushing plate and a telescopic driving member, the mounting frame is above the lifting conveying member, the mounting frame extends horizontally along the direction from the lifting paper conveying mechanism to the conveying mechanism, the paper pushing frame can slide on the mounting frame along the direction of approaching or moving away from the conveying mechanism, the paper pushing plate is installed on the side of the paper pushing frame facing the conveying mechanism, the side of the paper pushing plate facing the conveying mechanism forms a pushing space, the paper pushing plate is provided with a through hole, the telescopic driving member has a telescopic driving end, the straight line where the moving direction of the telescopic driving end is located extends along the direction of approaching the conveying mechanism and is inclined upward, the telescopic driving end is provided with a tooth block, the tooth block can move in and out of the pushing space, and the side of the tooth block close to the conveying mechanism is a tooth surface; when the telescopic driving end moves in the direction away from the conveying mechanism and is inclined upward, the mounting frame can move in the direction of approaching the conveying mechanism.

[0006] The technical scheme has at least the following beneficial effects: The stacked paper stack is placed on the lifting conveying member, the lifting conveying member moves the paper stack along the horizontal direction of approaching the conveying mechanism, then the lifting conveying member rises until the upper surface of the paper stack is flush with the conveying surface of the conveying mechanism, the paper pushing frame moves in the direction of approaching the paper stack, the telescopic driving member drives the tooth block to move into the pushing space and makes the tooth block inserted into the bottom of the paper stack with a preset thickness, then the telescopic driving end drives the tooth block to move in the direction away from the conveying mechanism and is inclined upward, at the same time, the paper pushing frame moves horizontally in the direction of approaching the conveying mechanism, at this time, the moving distance of the paper pushing frame and the tooth block in the horizontal direction is the same, that is, the tooth block is relatively static in the horizontal direction and only moves upward, so that the tooth block drives the paper stack with a preset thickness to move upward synchronously, the paper stack with a preset thickness is separated from the remaining part of the original paper stack, then the paper pushing frame drives the paper pushing plate to move on the mounting frame until the paper pushing plate abuts against the separated paper stack, and the paper pushing frame continues to move so that the paper pushing plate pushes the paper stack to move to the conveying mechanism; In the application, the tooth block is inserted into the paper stack with a preset thickness and drives the paper stack to move upward, so that the paper stack with a large volume and weight can be separated from the original paper stack, the manual assistance for carrying large paper boards is reduced, the workload of workers is reduced, and the automation level of the feeding machine is improved; in addition, the telescopic driving member is inclined and telescopic, which can offset the movement of the paper pushing frame in the horizontal direction, that is, during the movement of the paper pushing frame driving the paper pushing plate to push the paper stack, the paper stack with a preset thickness is driven to move upward synchronously, the waiting time for separating the paper stack from the original paper stack before the pushing plate performs the pushing operation is reduced, and the working speed of the feeding machine is improved.

[0007] As a further improvement of the above technical solution, the rack is provided with a guide plate between the lifting paper feeding mechanism and the conveying mechanism, the guide plate can rotate around a horizontal axis, and 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 in the vertical direction, a paper stack shaping space is formed between the guide plate and the paper pushing plate.

[0008] Because after the tooth block moves one end of the paper stack upward, the other end of the top paper sheet in the paper stack may protrude partially out of the paper stack, causing subsequent paper stacks to be scattered on the conveying mechanism. By using the above technical solution, when the tooth block moves the paper stack vertically and does not move horizontally, the guide plate is rotated to the vertical state, the paper pushing plate pushes the separated paper stack, and the bottom lifting conveying member moves upward to push the side of the paper stack away from the paper pushing plate upward, so that the paper stack is in a horizontal state and the side away from the paper pushing plate becomes neat, allowing the paper stack to be pushed in a neat and stacked manner.

[0009] When the paper pushing plate pushes the paper stack to move to the conveying mechanism, the guide plate is rotated to abut against the conveying mechanism, and at this time the paper stack first abuts against the guide plate and smoothly enters the conveying mechanism under the action of the inclined guide plate, reducing the jamming of the paper stack between the lifting conveying member and the conveying mechanism.

[0010] As a further improvement of the above technical solution, the paper pushing rack is provided with a paper separating plate, which can move on the paper pushing rack in the horizontal direction into and out of the paper pushing space.

[0011] By using the above technical solution, when the tooth block moves the paper stack upward to separate it from the original paper stack, the paper separating plate moves into the paper pushing space, thereby being located between the separated paper stack and the paper stack, preventing the already grabbed paper stack from falling back onto the paper stack and improving the stability of the transfer of the paper stack between the lifting conveying member and the conveying mechanism.

[0012] As a further improvement of the above technical solution, the conveying mechanism includes a first conveying assembly and a second conveying assembly, the first conveying assembly is rotatably installed on the rack, the rotation axis of the first conveying assembly is located at one end thereof close to the lifting paper feeding mechanism, the second conveying assembly is rotatably installed on the rack, the rotation axis of the second conveying assembly is located at one end thereof close to the first conveying assembly, the height of the rotation shaft of the first conveying assembly is higher than the height of the rotation shaft of the second conveying assembly, the first conveying assembly can be rotated to a height at which the conveying end of the first conveying assembly is higher than or equal to the height at which the conveying start end of the second conveying assembly, the second conveying assembly is provided with a receiving cavity, the receiving cavity is located below the conveying end of the first conveying assembly, and a fish scale discharge port is formed on the side of the receiving cavity away from the first conveying assembly.

[0013] Because the feeding speed of the feeding machine at the lifting conveying part and the discharging speed at the second conveying assembly can be different, such as when the second conveying assembly of the feeding machine transports a complete paper stack to the next process equipment at a speed greater than the speed of placing a same paper stack at the lifting conveying part, there can be a situation that the lifting conveying part is still in the feeding process after the discharging at the second conveying assembly is completed, causing the equipment to stop and wait at the second conveying assembly, resulting in low production efficiency of the feeding machine. By adopting the above technical solution, first, as many paper stacks as possible are placed at the lifting conveying part, and then the horizontal paper pushing mechanism divides the paper stacks at the lifting conveying part into multiple paper stacks and transports them to the first conveying assembly, and the first conveying assembly further transports the paper stacks to the second conveying assembly. In this process, the transport speed of the first conveying assembly is increased to be greater than the transport speed of the second conveying assembly, so as to quickly transfer the paper stacks at the lifting conveying part to the first conveying assembly, facilitating the next paper stack to enter the empty lifting conveying part. When the first conveying assembly receives too many paper stacks, the conveying end of the first conveying assembly is lifted to be higher than the conveying start end of the second conveying assembly, the paper stacks fall from the conveying end of the first conveying assembly into the receiving cavity and are transported in a fish scale arrangement through the fish scale discharging port of the receiving cavity. After the first conveying assembly continuously feeds the paper stacks into the receiving cavity, the first conveying assembly becomes an empty state waiting for the lifting conveying part to place paper stacks, and the second conveying assembly can continuously release paper boards from the receiving cavity for work, reducing the stop of the conveying end of the second conveying assembly. This makes the feeding machine able to continuously work and improves the production efficiency.

[0014] As a further improvement of the above technical solution, the conveying mechanism further comprises a aligning assembly, the aligning assembly is installed at one end of the second conveying assembly close to the first conveying assembly, the receiving cavity is formed in the aligning assembly, and an opening is formed on the side of the aligning assembly facing the first conveying assembly.

[0015] By adopting the above technical solution, the aligning assembly is used as the receiving cavity, which can not only receive the paper stacks falling from the first conveying assembly, but also align the paper stacks falling into the second conveying assembly for discharging from the fish scale discharging port, reducing the use of material receiving components and the cost of the equipment.

[0016] As a further improvement of the above technical solution, the conveying end of the first conveying assembly is provided with an aligning baffle, the aligning baffle can rotate around a horizontal axis perpendicular to a straight line in the transport direction of the first conveying assembly, and the aligning baffle can rotate to the opening and form an aligning space with the aligning assembly.

[0017] By adopting the above technical scheme, when the first conveying assembly puts the paper stack into the second conveying assembly, because the paper stack is free falling, part of the paperboard may protrude out of the paper stack on the side away from the aligning assembly, which may affect the subsequent transmission thereof on the second conveying assembly. Therefore, when the paper stack falls into the second conveying assembly, the aligning baffle rotates towards the aligning assembly until it is located at the opening, and cooperates with the aligning assembly to limit the paperboard at the position within the aligning space, so that the plurality of paperboards in one paper stack are neatly stacked.

[0018] As a further improvement of the above technical scheme, the second conveying assembly comprises a belt, a first frame body and a second frame body, the first frame body is mounted to the rack, and the second frame body is slidably mounted to the second frame body along the length direction of the second conveying assembly, and the belt is wound around the first frame body and the second frame body.

[0019] By adopting the above technical scheme, the overall length of the second conveying assembly can be extended or shortened after the first frame body is moved on the second frame body, and then the first frame body can be rotated on the rack, so that the position of the conveying end of the second conveying assembly can be moved arbitrarily, thereby adapting to the feeding end of different equipment and improving the applicability of the corrugated paper feeding machine of the present application to different equipment.

[0020] As a further improvement of the above technical scheme, the aligning assembly can slide on the first frame body along the length direction of the second conveying assembly.

[0021] By adopting the above technical scheme, the slidable aligning assembly changes the position of the receiving cavity, so that the receiving cavity can better receive the paper stack falling from the first conveying assembly.

[0022] As a further improvement of the above technical scheme, the rack is provided with a recycling space below the conveying mechanism, and the lifting conveying member can be moved to the input end position of the recycling space.

[0023] By adopting the above technical scheme, when only the bottom support frame is left in one paper stack, the lifting conveying member is moved to the input end of the recycling space, and then the bottom support frame is conveyed into the recycling space along the original conveying direction of the lifting conveying member, while the next paper stack behind is conveyed into the lifting conveying member, thereby reducing the time consumed for reversing the conveying direction to send the bottom support frame out of the lifting conveying member, and improving the production efficiency.

[0024] As a further improvement of the above technical scheme, the rack is provided with a horizontal pushing assembly in the recycling space, and the horizontal pushing assembly has a horizontal pushing driving end which can move in the recycling space along a horizontal direction perpendicular to the conveying direction of the conveying assembly.

[0025] By adopting the technical scheme, when the bottom support frame enters the recycling space and moves to the horizontal moving driving part, the horizontal pushing driving end pushes the bottom support frame horizontally out of the rack, thereby forming an avoiding position for the first conveying assembly and the second conveying assembly capable of rotating above, and reducing the obstruction of recycling the bottom support frame.

[0033] With reference to Figure 1 , Figure 2 and Figure 3 , the corrugated paperboard feeding machine provided in the present application comprises a rack 1, a lifting paper feeding mechanism 2, a horizontal paper pushing mechanism 3 and a conveying mechanism 4 are arranged on the rack 1, a plurality of paperboards are stacked on the bottom support frame to form a paper stack, the entire paper stack is carried to the lifting paper feeding mechanism 2, the paper stack formed by the upper part of the paperboard 36 is transferred to the conveying mechanism 4 through the lifting paper feeding mechanism 2 and the horizontal pushing mechanism, and the plurality of paperboards of the paper stack are arranged in a fish scale shape on the conveying mechanism 4, and then conveyed to the printing machine, the slotting machine, the die cutting machine and other carton processing equipment through the conveying mechanism 4 to complete the processing of the paperboard.

[0034] The lifting paper feeding mechanism 2 comprises a lifting conveying member 21 capable of moving in the up-down direction on the frame 1, specifically, the lifting conveying member 21 comprises a lifting conveying belt, the frame 1 is provided with a lifting driving member 22, the lifting conveying belt is connected to the lifting driving member 22 at both ends in the horizontal direction perpendicular to the conveying direction of the lifting conveying belt, the lifting conveying belt is driven to slide in the up-down direction on the frame 1 by the lifting driving member 22, and the lifting driving member 22 comprises a gear and rack driving mechanism or a synchronous belt mechanism, which is not limited in the embodiment of the application.

[0035] Further, the lifting paper feeding mechanism 2 further comprises a paper stack conveying belt (not shown in the figure), which is located on the side of the lifting conveying belt away from the conveying mechanism 4, the paper stack conveying belt can sequentially arrange and place a plurality of paper stacks, and the paper stack conveying belt can be flush with the lifting conveying member moving downward to the bottom of the frame 1, when the paper stack conveying belt and the lifting conveying member are flush, the paper stack can be directly transported to the lifting conveying member.

[0036] The conveying mechanism 4 is installed downstream of the lifting paper feeding mechanism 2, the conveying mechanism 4 is formed with a conveying surface, and the lifting conveying member 21 can move upward to the conveying surface on the frame 1.

[0037] Referring to Figure 4 , the horizontal paper pushing mechanism 3 is installed on the frame 1, the horizontal paper pushing mechanism 3 comprises a mounting frame 31, a paper pushing frame 32, a paper pushing plate 33 and a telescopic driving member 34, the mounting frame 31 is located above the lifting conveying member 21, the mounting frame 31 extends horizontally in 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 the direction close to or away from the conveying mechanism 4, the paper pushing plate 33 is installed on the side of the paper pushing frame 32 facing the conveying mechanism 4, the side of the paper pushing plate 33 facing the conveying mechanism 4 forms a pushing space, the paper pushing plate 33 is provided with a perforation, the telescopic driving member 34 has a telescopic driving end, the straight line where the moving direction of the telescopic driving end extends is inclined downward in the direction close to the conveying mechanism 4, the telescopic driving end is provided with a tooth block 35, the tooth block 35 can move through the perforation and in and out of the pushing space, and the side of the tooth block 35 close to the conveying mechanism 4 is a tooth surface, the tooth surface extends in the vertical direction, and when the telescopic driving end moves in the direction away from the conveying mechanism 4 and is inclined upward, the mounting frame 31 can move in the direction close to the conveying mechanism 4.

[0038] From the above, the stacked paper pile is placed on the lifting conveying member 21, the lifting conveying member 21 moves the paper pile along the horizontal close moving conveying mechanism 4 direction, then the lifting conveying member 21 rises until the paper pile upper surface is flush with the conveying surface of the conveying mechanism 4, the paper pushing frame 32 moves towards the close paper pile direction, the telescopic driving member 34 drives the tooth block 35 to move into the pushing space and makes the tooth block 35 inserted into the bottom of the paper stack of the preset thickness, then the telescopic driving end drives the tooth block 35 to move away from the conveying mechanism 4 and in the obliquely upward direction, at the same time, the paper pushing frame 32 moves horizontally towards the conveying mechanism 4 direction, at this time, the moving distance of the paper pushing frame 32 and the tooth block 35 in the horizontal direction is the same, that is, the tooth block 35 is relatively static in the horizontal direction, only the upward moving distance exists, so that the tooth block 35 drives the paper stack of the preset thickness to move upward synchronously, so that the paper stack of the preset thickness and the remaining part of the original paper pile are separated from each other, then the paper pushing frame 32 drives the paper pushing plate 33 to move on the mounting frame 31 until the paper pushing plate 33 abuts against the separated paper stack, the paper pushing frame 32 continues to move so that the paper pushing plate 33 pushes the paper stack to move to the conveying mechanism 4; In the present application, the tooth block 35 is inserted and drives the paper stack of the preset thickness to move upward, so that the paper stack with large volume and weight can be separated from the original paper pile, reducing the manual assistance for carrying large paper boards and reducing the workload of workers, improving the automation level of the feeding machine. Secondly, by setting the obliquely telescopic telescopic driving member 34, the movement of the paper pushing frame 32 in the horizontal direction can be offset, that is, during the process of moving the paper pushing plate 33 driven by the paper pushing frame 32 to push the paper stack, the paper stack of the preset thickness is synchronously lifted, reducing the waiting time of the paper stack and the original paper pile before the pushing operation of the paper pushing plate 33, and speeding up the working speed of the feeding machine.

[0039] In the present embodiment, the telescopic driving member 34 includes a telescopic driving cylinder, the telescopic driving cylinder is fixedly installed on the paper pushing frame 32, the piston rod of the telescopic driving cylinder extends towards the conveying mechanism 4 direction and is inclined downward, the slide rail for limiting the movement track of the tooth block 35 is arranged on the rack 1, the tooth block 35 is slidably installed on the slide rail and connected to the end of the piston rod of the telescopic driving cylinder.

[0040] Specifically, the mounting frame 31 is provided with a horizontal moving driving member 311 for driving the paper pushing frame 32 to move along the horizontal close or away from the conveying mechanism 4 direction on the mounting frame 31. The horizontal moving driving member 311 can be a gear chain driving mechanism or a rodless cylinder slider mechanism, which is not limited in the present embodiment.

[0041] Reference Figure 5In the embodiment, because after the tooth block 35 drives one end of the paper stack to move upward, the other end of the top paperboard in the paper stack can protrude out of the paper stack, resulting in the subsequent paper stack being scattered on the conveying mechanism 4, the frame 1 is provided with a guide plate 11 between the lifting paper conveying mechanism 2 and the conveying mechanism 4, the guide plate 11 can rotate around a horizontal axis, and 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 in the vertical direction, the guide plate 11, the lifting conveying member 21 and the paper pushing plate 33 form a paper stack shaping space.

[0042] As can be seen from the above, when the tooth block 35 drives the paper stack to move vertically and not horizontally, the guide plate 11 is rotated to the vertical state, the paper pushing plate 33 pushes the separated paper stack, and the bottom lifting conveying member 21 moves upward to push the side of the paper stack away from the paper pushing plate 33 upward, so that the paper stack is in a horizontal state and the side away from the paper pushing plate 33 becomes neat, enabling the paper stack to be pushed in a neat stacked posture. When the paper pushing plate 33 drives the paper stack to move to the conveying mechanism 4, the guide plate 11 is rotated to abut against the conveying mechanism 4, and at this time, the paper stack first abuts against the guide plate 11 and then smoothly enters the conveying mechanism 4 under the action of the inclined guide plate 11, reducing the jamming of the paper stack between the lifting conveying member 21 and the conveying mechanism 4.

[0043] Specifically, one end of the guide plate 11 is rotatably installed on the frame 1, and the other end is a free end. The frame 1 is rotatably provided with a guide plate rotating cylinder 12, and the guide plate rotating cylinder 12 is rotatably connected to the middle part of the side of the guide plate 11 close to the conveying assembly. When the piston rod of the guide plate rotating cylinder 12 extends or retracts, the guide plate 11 is driven to rotate.

[0044] Further, both ends of the guide plate 11 are provided with guide arc surfaces, which improve the smoothness of the movement of the paper stack on the guide plate 11.

[0045] As a further embodiment, the paper pushing frame 32 is provided with a paper separating plate 36 at the bottom, and the paper separating plate 36 can move on the paper pushing frame 32 in the horizontal direction into and out of the paper pushing space. After the tooth block 35 drives the paper stack to move upward and separate from the original paper stack, the paper separating plate 36 moves into the paper pushing space, so as to be 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 transfer of the paper stack between the lifting conveying member 21 and the conveying mechanism 4.

[0046] Specifically, the paper pushing frame 32 is provided with a paper separating pushing cylinder 361, the paper pushing frame 32 is provided with a paper separating moving slide rail, the paper separating plate 36 is slidably installed on the paper separating moving slide rail, and the piston rod of the paper separating pushing cylinder 361 is connected to the paper separating plate 36.

[0047] Because the feeding speed of the feeding machine at the lifting conveying part 21 and the discharging speed at the second conveying assembly 42 can be different, for example, when the second conveying assembly 42 of the feeding machine transports a complete paper stack to the next process equipment at a speed greater than the speed of placing a same paper stack at the lifting conveying part 21, there can be a situation that the lifting conveying part 21 is still in the feeding process after the discharging at the second conveying assembly 42 is completed, resulting in the equipment waiting at the second conveying assembly 42, and the production efficiency of the feeding machine is low. Therefore, in the embodiment, referring to Figure 3 and Figure 6 , the conveying mechanism 4 comprises a first conveying assembly 41 and a second conveying assembly 42, the first conveying assembly 41 is rotatably installed on the frame 1, and the rotation axis of the first conveying assembly 41 is located at the end close to the lifting paper conveying mechanism 2, the second conveying assembly 42 is rotatably installed on the frame 1, and the rotation axis of the second conveying assembly 42 is located at the end close to the first conveying assembly 41, the height of the rotation shaft of the first conveying assembly 41 is higher than the height of the rotation shaft of the second conveying assembly 42, the first conveying assembly 41 can rotate to the height of the conveying end being higher than or equal to the height of the conveying start end of the second conveying assembly 42, the second conveying assembly 42 is formed with a receiving cavity 431, the receiving cavity 431 is located below the conveying end of the first conveying assembly 41, and a fish scale discharging port is formed on the side of the receiving cavity 431 away from the first conveying assembly 41, and the first conveying assembly 41 can rotate to be parallel to the conveying surface of the second conveying assembly 42.

[0048] In the embodiment, the first conveying assembly 41 and the second conveying assembly 42 are both conveying belts.

[0049] As can be seen from the above, first, as many paper stacks as possible are placed at the lifting conveying part 21, then the horizontal paper pushing mechanism 3 divides the paper stacks at the lifting conveying part 21 into multiple paper stacks and conveys the paper stacks to the first conveying assembly 41, and the first conveying assembly 41 conveys the paper stacks to the second conveying assembly 42, in the process, the conveying speed of the first conveying assembly 41 is increased to be greater than the conveying speed of the second conveying assembly 42, so as to quickly transfer the paper stacks at the lifting conveying part 21 to the first conveying assembly 41, and facilitate the next paper stack to enter the empty lifting conveying part 21; When the first conveying assembly 41 receives too much paper stack, the conveying end of the first conveying assembly 41 is lifted to be higher than the conveying start end of the second conveying assembly 42, the paper stack falls from the conveying end of the first conveying assembly 41 into the receiving cavity 431 and is transmitted in a shingle arrangement through the shingle discharge port of the receiving cavity 431, after the first conveying assembly 41 continuously feeds the paper stack into the receiving cavity 431 and becomes in an empty state of waiting for the lifting conveying part 21 to place the paper stack, the second conveying assembly 42 can continuously release the paperboard from the receiving cavity 431 to work, reducing the stop of the conveying end of the second conveying assembly 42, so that the feeding machine can continuously work, improving the production efficiency, and the second conveying assembly 42 which can rotate and has a height difference with the first conveying assembly 41 can be rotated to be inclined with the conveying end downward, when the paper stack enters the second conveying assembly 42 which is inclined downward, the inclined receiving cavity can prevent the paper stack after free fall from falling towards the first conveying assembly 41, so that the paper stack can stably fall onto the second conveying assembly 42; Further, when the paper stack is gradually stacked in the receiving cavity 431 of the second conveying assembly 42, the total height of the paper stack gradually increases, the conveying end of the first conveying assembly 41 is gradually lifted until the conveying surface of the first conveying assembly 41 is flush with the horizontal plane, through this design, the first conveying assembly 41 gradually adapts to the continuously stacked paper stack, reducing the impact of the first conveying assembly 41 on the increased paper stack.

[0050] Specifically, the first conveying assembly rotating cylinder 411 and the second conveying assembly rotating cylinder 421 are arranged on the rack 1, the first conveying assembly rotating cylinder 411 and the second conveying assembly rotating cylinder 421 are both rotationally installed on the rack 1, the piston rod of the first conveying assembly rotating cylinder 411 is rotationally connected to one end of the first conveying assembly 41 away from the rotationally connected part of the first conveying assembly 41 and the rack 1, the piston rod of the second conveying assembly rotating cylinder 421 is rotationally connected to one end of the second conveying assembly 42 away from the rotationally connected part of the second conveying assembly 42 and the rack 1, the first conveying assembly 41 and the second conveying assembly 42 can be stably driven to rotate on the rack 1 through the first conveying assembly rotating cylinder 411 and the second conveying assembly rotating cylinder 421.

[0051] As a further embodiment, the conveying mechanism 4 further comprises a straightening assembly 43, the straightening assembly 43 is arranged on one end of the second conveying assembly 42 close to the first conveying assembly 41, the straightening assembly 43 forms a receiving cavity 431, the receiving cavity 431 is formed with an opening towards the first conveying assembly, and a shingle discharge port is formed between the side of the straightening assembly 43 away from the first conveying assembly 41 and the conveying surface of the second conveying assembly 42.

[0052] Specifically, the aligning assembly 43 comprises 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 is provided with the front aligning plate along the side close to the first conveying assembly 41. The aligning frame is provided with the side aligning plates along the two sides perpendicular to the transmission direction of the second conveying assembly 42. The front aligning plate and the two side aligning plates form a receiving cavity 431 with an opening.

[0053] As can be seen from the above, the aligning assembly 43 is used as the receiving cavity 431. The paper stack falling from the first conveying assembly 41 can be received. The paper stack falling into the second conveying assembly 42 can be aligned to facilitate the discharge from the fish scale discharge port. The use of the receiving component is reduced. The cost of the equipment is reduced.

[0054] As a further embodiment, referring to Figure 7 , the conveying end of the first conveying assembly 41 is provided with an aligning baffle 44. The aligning baffle 44 can rotate around a horizontal axis perpendicular to the straight line where the transmission direction of the first conveying assembly 41 is located. The aligning baffle 44 can be rotated to the opening and cooperatively form an aligning space with the receiving cavity 431 of the aligning assembly 43.

[0055] As can be seen from the above, when the first conveying assembly 41 discharges the paper stack to the second conveying assembly 42, because the paper stack is a free fall, part of the paperboard 36 may protrude to the outside of the paper stack away from the aligning assembly 43, which may affect the subsequent transmission of the paperboard on the second conveying assembly 42. Therefore, when the paper stack falls into the second conveying assembly 42, the aligning baffle 44 is rotated to the opening close to the aligning assembly 43 until it is located at the opening. The aligning baffle 44 cooperatively limits the paperboard at the opening in the aligning space, so that the multiple paperboards in a paper stack are neatly stacked.

[0056] In the present embodiment, the aligning rotating drive cylinder is rotatably installed on the first conveying assembly 41. The piston rod of the aligning rotating drive cylinder is rotatably connected to the aligning baffle 44.

[0057] As a further embodiment, the second conveying assembly 42 comprises a belt, a first frame body 422 and a second frame body 423. The first frame body 422 is installed on the rack 1. The second frame body 423 is slidably installed on the second frame body 423 along the length direction of the second conveying assembly 42. The belt is wound around the first frame body 422 and the second frame body 423.

[0058] As can be seen from the above, the first frame body 422 is moved on the second frame body 423. The overall length of the second conveying assembly 42 can be extended or shortened. Then, the first frame body 422 can be rotated on the rack 1. The position of the conveying end of the second conveying assembly 42 can be moved arbitrarily. Thus, the feeding end of the equipment can be adapted to different equipment. The applicability of the corrugated paper feeding machine of the present application to different equipment is improved.

[0059] As a further implementation, the aligning assembly 43 is capable of sliding along the length direction of the second conveying assembly 42 on the first frame body 422, and the slidable aligning assembly 43 changes the position of the receiving cavity 431, so that the receiving cavity 431 better receives the paper stack falling from the first conveying assembly 41.

[0060] Specifically, the aligning driving member is arranged outside the first frame body 422 and is used to drive the aligning frame to move on the first frame body 422. In the embodiment, the aligning driving member includes a gear and rack driving structure.

[0061] As a further implementation, the machine frame 1 is provided with a recycling space 5 below the conveying mechanism 4, and the lifting conveying member 21 is capable of moving to the input end position of the recycling space 5. When only the bottom support frame is left in a paper stack, the lifting conveying member 21 moves to the input end of the recycling space 5, and then the bottom support frame is conveyed to the recycling space 5 along the original conveying direction of the lifting conveying member 21, while the next paper stack behind is conveyed to the lifting conveying member 21. The time consumed by reversing the conveying direction to send the bottom support frame out of the lifting conveying member 21 is reduced, and the production efficiency is improved.

[0062] Specifically, the machine frame 1 is provided with a blocking baffle 51 between the recycling space 5 and the lifting paper conveying mechanism 2, and the blocking baffle 51 is capable of rotating on the machine frame 1. When the blocking baffle 51 rotates to move in the vertical direction, the paper stack is blocked from being moved from the lifting conveying member 21 to the recycling space 5. When the lifting conveying member 21 has conveyed all the paper boards on the paper stack and only the bottom support frame is left, the lifting conveying member 21 then moves downward to the input end of the recycling space 5, and then the blocking baffle 51 rotates to open and the lifting conveying member 21 starts to convey the support frame to the recycling space 5. The machine frame 1 is provided with a recycling conveying belt in the recycling space 5. After the support frame enters the recycling space 5, it is conveyed to the side of the recycling space 5 away from the lifting feeding mechanism by the recycling conveying belt, so as to reserve space for the next support frame.

[0063] Further, the machine frame 1 is provided with a horizontal pushing assembly 52 in the recycling space 5. The horizontal pushing assembly 52 has a horizontal pushing driving end, which is capable of moving in the recycling space 5 along a horizontal direction perpendicular to the conveying direction. When the bottom support frame enters the recycling space 5 and moves to the horizontal pushing driving end, the horizontal pushing driving end pushes the bottom support frame out of the machine frame 1 horizontally, so as to avoid the first conveying assembly 41 and the second conveying assembly 42 above from rotating and reduce the obstruction of recycling the bottom support frame.

[0064] Specifically, the horizontal pushing assembly 52 comprises a pushing frame and a horizontal pushing driving member for driving the pushing frame to move in the recycling space 5 in a direction perpendicular to the conveying mechanism 4. In this embodiment, the horizontal pushing driving member comprises a gear and rack driving structure, and the pushing frame moves under the driving of the horizontal pushing driving member.

[0065] The preferred embodiments of the present application have been specifically described above, but the present application is not limited to the above-described embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
