Description

Technical Field

[0001] The present application relates to the technical field of paper product production, and in particular to a material leveling and blocking device for a cardboard production line. Background Art

[0002] At present, the corrugated cardboard production line, referred to as the corrugated line, is the key production equipment of corrugated box manufacturers. The corrugated line can trim, crease, punch, etc. the corrugated cardboard, and finally stack it through a stacking machine.

[0003] Existing Chinese patent with announcement number CN214688172U discloses a cardboard slotting machine stacking mechanism for carton production, including a frame, a feeding platform for conveying cardboard is provided on the frame, a mounting frame is provided on the frame at the discharge port of the feeding platform, and a baffle plate is provided on the mounting frame extending downward from one end of the feeding platform, and a receiving frame is provided between the baffle plate and the lower part of the discharge end of the feeding platform.

[0004] With respect to the above-mentioned related technologies, the receiving rack is mostly a pallet. The processed cardboard falls from the end of the corrugation line onto the receiving rack. The lower end of the baffle is close to the ground. Due to the obstruction of the baffle, the cardboard can be continuously and stably stacked on the receiving rack. Among them, the cardboard stacked to a certain height is removed together with the pallet by a forklift, and then the pallet is placed on the ground between the end of the corrugation line and the baffle by a forklift or manually. However, since the baffle is opposite to the cardboard conveying direction at the end of the corrugation line, it is necessary to deliver the pallet to the ground between the end of the corrugation line and the baffle from both sides of the cardboard conveying direction. In particular, when the space on both sides of the gap is limited, it is difficult for the forklift to place the pallet into the gap. Summary of the Invention

[0005] In order to increase the directions in which a forklift can place pallets and facilitate the forklift to quickly place the pallets, the present application provides a leveling and blocking device for a cardboard production line.

[0006] The present application provides a material leveling and blocking device for a cardboard production line that adopts the following technical solution:

[0007] A material leveling and blocking device for a cardboard production line comprises a frame and a material blocking portion, the material blocking portion comprising a fixed portion and a sliding portion, the material blocking portion being arranged on the frame, the sliding portion being slidably connected to the fixed portion, the sliding portion sliding along the height direction, the fixed portion and the sliding portion forming a limiting surface on the side facing the end of the corrugated line, the fixed portion being provided with a power part for driving the sliding portion to slide; when the sliding portion slides downward and out of the lower end of the fixed portion, the area of the limiting surface increases.

[0008] By adopting the above technical solution, one side of the fixed part and the sliding part forms a limiting surface for the cardboard. When it is necessary to put a pallet between the material stopper and the end of the corrugated line, the sliding part can be slid upward by the power part, so that the gap between the lower end of the material stopper and the ground becomes larger; therefore, the forklift can also transport the pallet to the required position from the lower end of the material stopper in the direction opposite to the end of the corrugated line, that is, the position between the end of the corrugated line and the material stopper; after the pallet is placed, the sliding part is moved downward and lower than the upper surface of the pallet, so that the area of the limiting surface becomes larger, ensuring that the side of the pallet away from the end of the corrugated line is blocked; because sometimes the space on the side of the material stopper away from the end of the corrugated line is larger than the space on both sides of the cardboard conveying direction, it can be more convenient for the forklift to turn and move, so the forklift can increase the direction of putting in the pallet, so as to achieve the effect of facilitating the forklift to quickly place the pallet.

[0009] Preferably, the fixing portion is slidably connected to the frame, the fixing portion slides horizontally in a direction approaching or away from the end of the corrugated line, and a driving component for driving the fixing portion to slide is provided on the frame.

[0010] By adopting the above technical solution, due to the differences in the widths of different cardboards, the driving component can be used to drive the entire material stop to slide, thereby adjusting the distance between the material stop and the end of the corrugated line to better limit and stack cardboards of different sizes.

[0011] Preferably, the fixed part includes a first frame and several first vertical bars, the first vertical bars are fixed to the first frame at intervals and vertically, the sliding part includes a second frame and several second vertical bars, the second vertical bars are fixed to the second frame vertically and at intervals, the second frame is slidably connected to the first frame, each second vertical bar is correspondingly arranged between two adjacent first vertical bars, and the first vertical bar and the second vertical bar are both located on the limiting surface.

[0012] By adopting the above technical solution, the overall weight of the material blocking part is lowered by the fixed part formed by the first frame and the first vertical bar, and the movable part formed by the second frame and the second vertical bar; the second vertical bar is located between each two adjacent first vertical bars, ensuring that the first vertical bar and the second vertical bar can be in the same plane; when the lower end of the sliding part slides out of the lowest position of the first frame, the limiting surface of the material blocking part gradually becomes larger.

[0013] Preferably, the first vertical bar includes a first vertical plate and two first bent plates, the first bent plates are fixed to two vertical sides of the first vertical bar and extend in a direction away from the end of the tile line, and the first bent plates are fixed to the first frame.

[0014] By adopting the above technical solution, a first bent plate is fixed on the vertical side of the first vertical plate to form a first vertical bar, so that the first vertical plate is not easily bent or deformed, thereby ensuring the structural strength of the first vertical bar when the thickness of the first vertical plate is small.

[0015] Preferably, the second vertical bar includes a second vertical plate and two second bent plates, the second bent plates are fixed to two vertical sides of the second vertical bar and extend in a direction away from the end of the tile line, and the second bent plates are fixed to the second frame.

[0016] By adopting the above technical solution, a second bent plate is fixed on the vertical side of the second vertical plate to form a second vertical bar, so that the second vertical plate is not easily bent and deformed, thereby ensuring the structural strength of the second vertical bar when the thickness of the second vertical plate is small.

[0017] Preferably, a collecting portion is provided at the lower end of the second frame along its horizontal length direction, and a collecting groove is provided on the upper side of the collecting portion. The notch of the collecting groove is located below the limiting surface, and the notch position of the collecting groove is lower than the upper surface position of the pallet.

[0018] By adopting the above technical solution, when the cardboard slides from the end of the corrugated line and is stacked on the pallet, part of the cardboard will hit the side of the first vertical bar or the second vertical bar facing the end of the corrugated line, so that debris will be generated and fall; by setting the cooperation between the collection part and the collection trough, the debris can be easily dropped into the first collection trough, so that the debris can be collected.

[0019] Preferably, a positioning frame is provided at the lower end of the second frame, and the collecting part is snap-connected to the positioning frame.

[0020] By adopting the above technical solution, the collecting part can be positioned and connected conveniently through the positioning frame, thereby realizing a detachable connection between the collecting part and the second frame, making it easy to remove the collecting part and clean up the debris in the collecting tank.

[0021] Preferably, a cover plate is rotatably connected to the positioning frame, and the cover plate is used to cover or open the notch of the collection tank. A top rod is provided at the end of the positioning frame for sliding along the height direction, the lower end of the top rod abuts the ground, and the upper end abuts the lower surface of the cover plate; when the second frame slides up and down, the lower end of the top rod always abuts the ground; when the second frame is at the lowest position, the cover plate is located in a position that is in contact with the second vertical bar toward the end of the tile line, and the cover plate is in a state of opening the notch of the collection tank; when the second frame slides to near the highest position, the cover plate is in a horizontal state and covers the notch of the collection tank.

[0022] By adopting the above technical solution, when the material blocking part and the collection trough are not in use, the second frame, the collection part and the cover plate can be moved upward synchronously by the power part. At this time, the top rod moves downward relative to the cover plate, so the cover plate also rotates downward until the cover plate covers the notch of the collection trough, thereby reducing the debris in the collection trough from being affected by the external airflow and flying away; and when the material blocking part and the collection trough are in use, the second frame moves downward to the lowest position. At this time, the top rod moves upward relative to the cover plate and the second frame, and then pushes the cover plate upward, so that the notch of the collection trough is opened.

[0023] Preferably, the bottom of the top rod is rotatably connected to a roller, and the roller is rollingly connected to the ground.

[0024] By adopting the above technical solution and setting rolling, the friction between the top rod and the ground can be reduced.

[0025] Preferably, a mounting bracket is fixed to the upper end of the fixed portion, a pulley is rotatably connected to the upper end of the mounting bracket, and the pulley is rollingly connected to the frame; the driving assembly includes a synchronous belt fixed to the upper end of the frame, a transmission gear rotatably connected to the mounting bracket, and a motor arranged on the mounting bracket, the motor is connected to the transmission gear, and the transmission gear is meshed with the synchronous belt.

[0026] By adopting the above technical solution, the mounting frame can be slid on the frame through the pulley; when the motor drives the gear to rotate, it is limited by the engagement of the synchronous belt, so that the mounting frame and the material stop part can slide, realizing the sliding drive of the material stop part by the drive component.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The embodiment of the present application discloses a material leveling and blocking device for a cardboard production line. Figure 1 The material leveling and blocking device includes a frame 1 and a material blocking portion 2. The frame 1 includes a top frame 101 and several uprights 102. The top frame 101 is located at the upper end of the uprights 102. The top frame 101 is rectangular in shape, and there are four uprights 102 located at the four corners of the top frame 101. The material blocking portion 2 and the end of the corrugation line are opposite and spaced apart. The pallet 20 is placed on the ground between the material blocking portion 2 and the end of the corrugation line. The direction in which the cardboard is conveyed from the end of the corrugation line is aligned with the length of the top frame 101. After the first cardboard falls from the corrugation line, it falls onto the upper surface of the pallet 20 and gradually stacks upward.

[0038] Among them, reference Figure 2 and Figure 3The material stopper 2 includes a fixed portion 21 and a sliding portion 22. The upper end of the material stopper 2 is horizontally slidably connected to the top frame 101, and the sliding portion 22 is slidably connected to the position of the fixed portion 21 near the lower end. The sliding portion 22 slides along the height direction, and the fixed portion 21 and the sliding portion 22 form a limiting surface toward the end of the corrugated line. When the cardboard slides from the end of the corrugated line, one side of the cardboard will be restricted by the limiting surface of the material stopper 2, so that each cardboard can be stably stacked. A power part 3 is provided on the fixed portion 21 for driving the sliding portion 22 to slide. When the sliding portion 22 slides downward out of the outermost end of the fixed portion 21 and makes the lower end position of the sliding portion 22 lower than the upper surface of the pallet 20, the area of the limiting surface increases, ensuring that the material stopper can more completely block the side of the pallet 20 away from the end of the corrugated line, so that the cardboard is not likely to slide off in a large range when stacking.

[0039] The fixing portion 21 slides along the length direction of the top frame 101, so that the stopper 2 can be adjusted in the direction close to or away from the end of the corrugated line, thereby adjusting the spacing distance between the stopper 2 and the end of the corrugated line to adapt to the position limitation when stacking cardboards of different sizes.

[0040] A mounting bracket 4 is fixed to the upper end of the fixed portion 21, and pulleys 5 are rotatably connected at both ends of the mounting bracket 4. The pulleys 5 are fixedly connected to the long sides of the top frame 101, so as to achieve smooth sliding of the stopper 2 on the frame 1. A driving assembly 6 for driving the fixed portion 21 to slide is provided on the frame 1. Specifically, the driving assembly 6 includes a synchronous belt 61 fixed to the long sides of the top frame 101, a transmission gear 62 rotatably connected to the mounting bracket 4, and a motor 63 fixed to the mounting bracket 4. The synchronous belt 61 is fixedly set along the length direction of the top frame 101, the motor 63 is connected to the transmission gear 62, and the transmission gear 62 and the synchronous belt 61 are meshed with each other; the motor 63 is selected as a servo motor 63. When the motor 63 drives the transmission gear 62 to rotate, the transmission gear 62 and the mounting bracket 4 can be moved relative to the synchronous belt 61, so as to achieve the movement control of the stopper 2.

[0041] Among them, reference Figure 2 and Figure 4The fixed portion 21 includes a first frame 211 and a plurality of first vertical bars 212. The first frame 211 is rectangular and perpendicular to the length direction of the top frame 101. The first vertical bars 212 are spaced apart and vertically fixed to the side of the first frame 211 facing the end of the tile line. The sliding portion 22 includes a second frame 221 and a plurality of second vertical bars 222. The second frame 221 is rectangular and perpendicular to the length direction of the top frame 101. The second vertical bars 222 are vertically and spaced apart and fixed to the second frame 221. Each second vertical bar 222 is correspondingly arranged between two adjacent first vertical bars 212. The first vertical bars 212 and the second vertical bars 222 are both located on the limiting surface. The second frame 221 is slidably connected to the first frame 211. Specifically, a guide rod 7 is vertically fixed near the lower end of the first frame 211. A slider 8 is sleeved on the guide rod 7 and slidably connected. The slider 8 is fixed to the second frame 221. The power member 3 is a pneumatic cylinder or an oil cylinder vertically mounted on the first frame 211 , and a telescopic rod of the pneumatic cylinder or the oil cylinder is fixed to the second frame 221 .

[0042] The first vertical bar 212 comprises a first riser 9 and two first bent plates 10. The first bent plates 10 are fixed perpendicularly to the vertical sides of the first vertical bar 212 and extend away from the end of the tile line. The first bent plates 10 are welded to the first frame 211 and are formed by bending. Therefore, when the first riser 9 is relatively thin, the first bent plates 10 can increase the strength of the first vertical bar 212, while also making the first vertical bar 212 less prone to bending and reducing its weight.

[0043] The second vertical bar 222 includes a second vertical plate 11 and two second bent plates 12. The second bent plates 12 are fixed to the vertical sides of the second vertical bar 222 and extend away from the end of the tile line. The second bent plates 12 are formed by bending, and the length of the second vertical bar 222 is shorter than that of the first vertical bar 212. The second bent plates 12 are welded to the second frame 221. The first vertical plate 9 and the second vertical plate 11 are on the same vertical plane; therefore, when the second vertical plate 11 is thin, the second bent plates 12 can increase the strength of the second vertical bar 222, while preventing the second vertical bar 222 from bending, thereby reducing the weight of the second vertical bar 222.

[0044] Since the cardboard may touch the first vertical board 9 or the second vertical board 11 when stacking, some paper scraps may fall and float around, affecting the environment. Therefore, a collection portion 13 is detachably provided at the lower end of the second frame 221 along its own horizontal length direction. The collection portion 13 is located at the end of the second frame 221 facing the corrugated line; a collection trough 14 is provided on the upper side of the collection portion 13. The collection portion 13 is a rectangular trough with an open top. The notch of the collection trough 14 covers the bottom of the limit surface, and the notch position of the collection trough 14 is lower than the upper surface position of the pallet 20, so that the collection portion 13 will not affect the stacking of the cardboard. At the same time, the paper scraps that fall when the cardboard touches the first vertical board 9 or the second vertical board 11 fall into the collection trough 14, thereby collecting the paper scraps and reducing the impact of the paper scraps on the surrounding environment.

[0045] Among them, a positioning frame 15 is welded at the lower end of the second frame 221 along its own horizontal length direction. The positioning frame 15 is a frame with an open upper end. The collecting part 13 is snapped into the positioning frame 15 to achieve a detachable connection between the collecting part 13 and the second frame, which is convenient for cleaning paper scraps.

[0046] Reference Figure 4 and Figure 5 A cover plate 16 is rotatably connected to the upper side of the positioning frame 15, away from the end of the tile line. The rotation axis of the cover plate 16 is in the horizontal length direction of the second frame body. The cover plate 16 is used to cover or open the notch of the collection tank 14. A cylinder 17 is vertically welded to the outside of the end of the positioning frame 15. A push rod 18 is slidably connected to the cylinder 17 along the height direction. The lower end of the push rod 18 abuts the ground due to its own gravity, and the upper end abuts the lower surface of the cover plate 16.

[0047] When the second frame 221 slides up and down, the lower end of the top rod 18 is always in contact with the ground, and the upper end of the top rod 18 is always in contact with the cover plate 16 downward and toward one side of the collection trough 14; when the second frame 221 moves down to the lowest position, the top rod 18 moves upward relative to the second frame 221, pushing the cover plate 16 upward, so that the cover plate 16 is in a position in contact with the second vertical bar 222 toward the end of the tile line, and the cover plate 16 is close to the vertical position. At the same time, the cover plate 16 is in a state of opening the notch of the collection trough 14, ensuring that the collection trough 14 can collect paper scraps normally.

[0048] When the second frame 221 slides upward to a position close to the highest position, the top rod 18 moves downward relative to the second frame 221 due to its own weight and the pressure of the cover plate 16. As a result, the cover plate 16 gradually rotates downward to a horizontal position and covers the notch of the collection trough 14. Therefore, the power member 3 can simultaneously control the rotation of the cover plate 16 and, in turn, the opening and closing of the notch of the collection trough 14, thereby reducing the scattering of paper scraps to the surrounding area.

[0049] The bottom of the top rod 18 is rotatably connected to a roller 19, and the roller 19 is in rolling connection with the ground; therefore, when the material blocking portion 2 slides, the friction between the top rod 18 and the ground can be reduced.

[0050] The implementation principle of a leveling and blocking device for a cardboard production line according to an embodiment of the present application is as follows: when it is necessary to place a pallet 20 between the stopper 2 and the end of the corrugated line, the sliding portion 22 can be slid upward by the power member 3, thereby increasing the gap between the lower end of the stopper 2 and the ground. The pallet 20 can then be properly positioned to enter the gap between the stopper 2 and the end of the corrugated line through the gap at the lower end of the stopper 2. Therefore, a forklift can not only deliver the pallet 20 to the desired position from both sides of the cardboard conveying direction, but also deliver the pallet 20 from the direction opposite to the end of the corrugated line. After the pallet 20 is placed, the sliding portion 22 is moved downward to a position below the upper surface of the pallet 20, thereby increasing the area of the limiting surface and ensuring that the side of the pallet 20 away from the end of the corrugated line is blocked. Since the space on the side of the stopper 2 away from the end of the corrugated line is sometimes larger than the space on both sides of the cardboard conveying direction, it is more convenient for the forklift to turn and move. Therefore, the forklift can increase the number of directions in which the pallet 20 can be placed, thereby facilitating the forklift to quickly place the pallet 20.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
