Description

Technical Field

[0001] The present invention relates to the technical field of bundling devices, and particularly relates to an automatic bundling device for carton cardboard. Background Art

[0002] A bundling machine is a machine device used to bundle or tie objects together. It is mainly used in the packaging industry and the logistics field for bundling objects such as cartons, packages, pipes, and wood. The main purpose of the bundling machine is to provide a fast, stable, and safe bundling solution to reduce manual operations and improve work efficiency.

[0003] In the use of a cardboard bundling machine, the bundling force of the cardboard is mainly achieved by tightening the strapping. When tightening the strapping, the edges of the cardboard are subjected to greater force, and it is difficult to ensure the tightening force on the cardboard. The bundled cardboard is prone to loosening and scattering. Moreover, during the tightening process, the cardboard will be squeezed, and thus the paper scraps on the cut surface will be blown out, polluting the surrounding environment and the equipment itself. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem of uneven force during the bundling of cardboard in the prior art, and to propose an automatic bundling device for carton cardboard.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] To suck away the paper scraps generated when pressing the cardboard, preferably, the dust suction component includes two baffles fixedly connected to the lower end of the pressing plate, and the two baffles are arranged perpendicular to each other. Among them, cavities are provided in both of the two baffles, dust suction grooves communicating with the cavities are provided on the outer walls of the two baffles, a filter plate is fixedly installed at the inner top of the cavity, and a negative pressure component connected to the cavity is provided at the upper end of the pressing plate.

[0008] To automatically generate negative pressure in the dust suction groove, further, the negative pressure component includes an elastic telescopic airbag fixedly installed between the pressing plate and the top plate. An exhaust pipe and an air suction pipe are fixedly installed on the elastic telescopic airbag. Among them, one-way valves are fixedly installed in both the exhaust pipe and the air suction pipe, and the end of the air suction pipe extends to the inner top of the cavity.

[0009] In order to facilitate the collection of paper scraps on the filter plate, further, the lower end of the baffle is fixedly connected with an L-shaped bracket, and an upward-opening storage box is arranged on the L-shaped bracket. Among them, an opening aligned with the storage box is arranged at the lower end of the baffle. The filter plate is fixedly connected obliquely in the cavity, and a knocking component for knocking the filter plate is arranged at the inner top of the cavity. A handle is fixedly connected to the outer wall of the storage box.

[0010] In order to make the paper scraps on the filter plate fall off efficiently, further, the knocking component includes a plug rod slidably inserted into the upper end of the pressing plate. The lower end of the plug rod extends into the cavity and is fixedly connected with a buffer spring. Among them, the telescopic end of the buffer spring is fixedly connected with a knocking block for knocking the filter plate. The upper end of the plug rod is fixedly connected with a limiting plate, and the limiting plate and the pressing plate are elastically connected by a return spring. An impact plate aligned with the limiting plate up and down is fixedly connected to the frame.

[0011] In order to prevent the paper scraps on the filter plate from falling off from the dust suction groove, further, the lower end of the impact plate is fixedly connected with a plugging plate penetrating through the pressing plate, and the lower end side wall of the plugging plate fits on the port of the dust suction groove.

[0012] In order to prevent the paper scraps in the storage box from being adsorbed onto the filter plate again, further, a device groove is arranged on the outer wall of the baffle. An isolation plate extending into the cavity is rotatably connected in the device groove through a rotating rod. The plugging plate abuts against one end of the isolation plate, and the other end of the isolation plate is inclined towards the inner top of the cavity. A limiting block for limiting the isolation plate is fixedly connected to one side of the cavity far away from the rotating rod.

[0013] In order to improve the dust suction effect of the dust suction groove, further, an L-shaped rod is fixedly connected to one of the pressing plates.

[0016] Compared with the prior art, the present invention provides a carton cardboard automatic bundling device, which has the following beneficial effects:

[0017] 1. For this automatic cardboard bundling device for cartons, the telescopic device drives the pressing plate to move downward. The four pressing plates will press on the cardboard, and then a bundling operation is completed by the bundling machine. Then, the telescopic device drives the pressing plate to move upward and reset. During the bundling process, the cardboard is evenly compacted by the pressing plate, which can significantly improve the bundling effect of the cardboard and prevent loosening.

[0018] 2. For this automatic cardboard bundling device for cartons, the four pressing plates drive eight baffle plates to block around the cardboard, so that the paper scraps generated by the extrusion of the cardboard will not directly fly rapidly into the surrounding environment, reducing the pollution of the paper scraps to the surrounding environment.

[0019] 3. For this automatic cardboard bundling device for cartons, the pressing plate stretches the elastic telescopic airbag. The elastic telescopic airbag will suck the gas in the cavity of the baffle plate through the suction pipe. The dust suction groove will suck the paper scraps generated by the extrusion of the cardboard into the cavity of the baffle plate and filter them through the filter plate, thus preventing the paper scraps from polluting the surrounding environment and the bundling machine. On the one hand, it reduces the harm to the staff caused by the paper scraps, and on the other hand, it can reduce the situation that the bundling machine is stuck and damaged due to excessive dust.

[0020] 4. For this automatic cardboard bundling device for cartons, the L-shaped rod presses against the switch, and then the suction pipe starts to suck the air in the cavity of the baffle plate. At the moment of opening the solenoid valve, the elastic telescopic airbag will instantly suck the suction pipe under the action of the elastic force, so that the dust suction groove has a higher dust suction effect.

[0021] 5. For this automatic cardboard bundling device for cartons, the strip drives the driven gear to reverse. At this time, the driven gear drives the second belt drive to reverse through the rotating shaft, and multiple conveying wheels drive the cardboard on the bundling machine to move a certain distance, so that there is no need to manually move the cardboard to tie the second tie, making the bundling more convenient.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0034] Embodiment 1:

[0035] Refer to Figures 1-9, An automatic binding device for carton board, which includes a bundling machine 1 with the function of bundling board, and also includes: a top plate 3, fixedly connected to the upper end of the bundling machine 1. Among them, two pairs of telescopic devices 4 are fixedly installed at the lower end of the top plate 3. The telescopic devices 4 are electric telescopic rods with simple operation. The telescopic ends of the two pairs of telescopic devices 4 are fixedly connected with a pair of pressing plates 5. The two pairs of pressing plates 5 are respectively arranged on both sides of the frame 2 of the bundling machine 1, and a mechanism for bundling tie straps is arranged inside the frame 2; four dust suction components are respectively arranged at the lower ends of the four pressing plates 5, and the dust suction components are used to suck the dust generated during the bundling process.

[0036] When bundling the board, place the board on the operating table of the bundling machine 1. First, drive the pressing plate 5 to move downward through the telescopic device 4, and the four pressing plates 5 will press on the board. Then, complete a bundling operation through the bundling machine 1. Then, drive the pressing plate 5 to move upward and reset through the telescopic device 4. The board is evenly compacted by the pressing plate 5 during the bundling process, so that the bundling effect of the board can be significantly improved and it is not easy to appear loose. During the bundling process of the board, the four dust suction components will surround the board, so that the paper scraps generated by the board can be sucked away. On the one hand, it reduces the harm to the staff caused by the paper scraps, and on the other hand, it can reduce the situation that the bundling machine 1 is stuck and damaged due to excessive dust.

[0037] Embodiment Two:

[0038] Refer to Figures 1-7 , which is basically the same as Embodiment One. Furthermore, the specific implementation scheme of the dust suction component is specifically disclosed.

[0039] The dust suction component includes two baffle plates 6 fixedly connected to the lower end of the pressing plate 5. The two baffle plates 6 are arranged perpendicular to each other. Among them, cavities 34 are arranged inside the two baffle plates 6, and dust suction grooves 8 communicating with the cavities 34 are arranged on the outer walls of the two baffle plates 6. The dust suction grooves 8 are used to suck the paper scraps generated by the board. A filter plate 33 for filtering paper scraps is fixedly installed at the inner top of the cavity 34. A negative pressure component connected to the cavity 34 is arranged at the upper end of the pressing plate 5; the negative pressure component includes an elastic telescopic airbag 9 fixedly installed between the pressing plate 5 and the top plate 3. An exhaust pipe 11 and a suction pipe 10 are fixedly installed on the elastic telescopic airbag 9. Among them, one-way valves are fixedly installed in both the exhaust pipe 11 and the suction pipe 10, and the end of the suction pipe 10 extends to the inner top of the cavity 34.

[0040] When the pressing plate 5 moves upward to reset, the pressing plate 5 will compress the elastic telescopic airbag 9, and the elastic telescopic airbag 9 will discharge the internal air through the exhaust pipe 11. When the pressing plate 5 moves downward to press the cardboard, the four pressing plates 5 will drive the eight baffles 6 to block around the cardboard, so that the paper scraps generated by the extrusion of the cardboard will not directly splash quickly into the surrounding environment, reducing the pollution of the paper scraps to the surrounding environment. Moreover, the pressing plate 5 will also stretch the elastic telescopic airbag 9, and the elastic telescopic airbag 9 will suck the gas in the inner cavity 34 of the baffle 6 through the suction pipe 10. The cavity 34 will suck the paper scraps generated by the extrusion of the cardboard into the cavity 34 of the baffle 6 through the dust suction groove 8 and filter them through the filter plate 33, thus preventing the paper scraps from polluting the surrounding environment and the bundling machine 1. On the one hand, it reduces the harm of the paper scraps to the staff, and on the other hand, it can reduce the situation that the bundling machine 1 is stuck and damaged due to excessive dust.

[0041] Embodiment 3:

[0042] Referring to Figures 1-8 , it is basically the same as Embodiment 2. Further, a specific implementation scheme for automatically cleaning the filter plate 33 is specifically added.

[0043] The lower end of the baffle 6 is fixedly connected with an L-shaped bracket 12. An open-top storage box 7 is arranged on the L-shaped bracket 12. The storage box 7 is used to collect the paper scraps falling on the filter plate 33. Among them, the lower end of the baffle 6 is provided with an opening aligned with the storage box 7. The filter plate 33 is obliquely fixedly connected in the cavity 34. A knocking component for knocking the filter plate 33 is arranged at the inner top of the cavity 34. The outer wall of the storage box 7 is fixedly connected with a handle 13; The knocking component includes a plug rod 14 slidably inserted into the upper end of the pressing plate 5. The lower end of the plug rod 14 extends into the cavity 34 and is fixedly connected with a buffer spring 18. Among them, a knocking block 17 for knocking the filter plate 33 is fixedly connected to the telescopic end of the buffer spring 18. A limiting plate 15 is fixedly connected to the upper end of the plug rod 14. The limiting plate 15 is elastically connected with the pressing plate 5 through a reset spring 16. An impact plate 23 aligned with the limiting plate 15 up and down is fixedly connected to the frame 2;

[0044] After the pressing plate 5 drives the baffle 6 to move upward and reset, the pressing plate 5 will drive the limiting plate 15 to strike the impact plate 23. The limiting plate 15 will move downward and generate vibrations, and drive the plug rod 14 and the striking block 17 to move downward and generate vibrations. The striking block 17 will strike the inclined filter plate 33, and the paper scraps filtered on the filter plate 33 will fall into the storage box 7, thus automatically completing the cleaning work of the filter plate 33 and the automatic collection work of the paper scraps, effectively ensuring the efficiency of the filter plate 33 in filtering paper scraps. When the pressing plate 5 drives the baffle 6 to move downward, the impact plate 23 no longer presses against the limiting plate 15, and the reset spring 16 will drive the limiting plate 15, the plug rod 14 and the striking block 17 away from the filter plate 33. When it is necessary to clean the paper scraps in the storage box 7, the storage box 7 can be pulled out from the L-shaped bracket 12 through the handle 13, and the cleaning of the storage box 7 is also very simple and convenient.

[0045] Furthermore, a sealing plate 19 penetrating through the pressing plate 5 is fixedly connected to the lower end of the impact plate 23, and the lower end side wall of the sealing plate 19 is attached to the port of the dust suction groove 8;

[0046] After the baffle 6 moves downward, the sealing plate 19 will no longer block the dust suction groove 8. On the contrary, after the baffle 6 moves upward and resets, the sealing plate 19 will block the port of the dust suction groove 8. Therefore, the paper scraps falling on the filter plate 33 will not be discharged from the dust suction groove 8, ensuring the recycling effect of the paper scraps.

[0047] Embodiment 4:

[0048] Refer to Figure 7 And Figure 8 , which is basically the same as Embodiment 3. Furthermore, a specific implementation scheme for preventing the paper scraps in the storage box 7 from being sucked away twice is specifically added.

[0049] A device groove 20 is provided on the outer wall of the baffle 6. A partition plate 21 extending into the cavity 34 is rotatably connected in the device groove 20 through a rotating rod 22. One end of the sealing plate 19 abuts against the partition plate 21, and the other end of the partition plate 21 is inclined towards the inner top of the cavity 34. A limiting block 24 is fixedly connected to the side of the cavity 34 far from the rotating rod 22, and the limiting block 24 is used to limit the partition plate 21;

[0050] After the baffle 6 moves downward, the plugging plate 19 will no longer plug the dust suction groove 8 and will not press against the short side of the isolation plate 21. The long side of the isolation plate 21 will swing downward to reset and rest on the limit block 24. At this time, the isolation plate 21 will plug the inner bottom of the storage cavity 34, that is, the upper port of the storage box 7. So when the dust suction groove 8 sucks in paper scraps, it can prevent the negative pressure air flow from sucking away the paper scraps in the storage box 7. On the contrary, after the baffle 6 moves upward to reset, the plugging plate 19 will block the port of the dust suction groove 8. So the paper scraps falling on the filter plate 33 will not be discharged from the dust suction groove 8, ensuring the recycling effect of the paper scraps. And the lower end of the plugging plate 19 will also press against the isolation plate 21 extending out of the device groove 20. The short side of the isolation plate 21 will be pressed downward and inclined, and the long side of the isolation plate 21 will tilt upward. At this time, the inner bottom of the cavity 34 will not be plugged by the isolation plate 21, so that the paper scraps can slide into the storage box 7.

[0051] Embodiment Five:

[0052] Referring to Figures 1-6 and Figure 9 , it is basically the same as Embodiment Four. Furthermore, a specific implementation scheme for improving the efficiency of sucking paper scraps by the dust suction groove 8 is specifically added.

[0053] One of the pressing plates 5 is fixedly connected with an L-shaped rod 27. An electromagnetic valve is fixedly installed in the air suction pipe 10. The lower end of the frame 2 is fixedly connected with a switch 32 electrically connected to the electromagnetic valve. The lower end of the L-shaped rod 27 faces the switch 32. When the switch 32 is pressed, the electromagnetic valve opens. When not pressed, the electromagnetic valve closes.

[0054] When the pressing plate 5 moves downward, the pressing plate 5 will drive the L-shaped rod 27 to move downward synchronously. When the pressing plate 5 moves downward to the limit position, the L-shaped rod 27 will press against the switch 32, and the switch 32 will open the electromagnetic valve in the air suction pipe 10. Only then will the air suction pipe 10 start to suck air from the cavity 34 in the baffle 6. That is, after the cardboard is pressed by the pressing plate 5, the dust suction groove 8 will start to suck in paper scraps. And at the moment when the electromagnetic valve is opened, the elastic telescopic airbag 9 will instantaneously suck air from the air suction pipe 10 under the action of elastic force, so that the dust suction groove 8 has a higher dust suction effect.

[0055] A plurality of long strip-shaped conveying wheels 25 are rotatably installed on the operating platform of the bundling machine 1. When bundling the cardboard, the cardboard is placed on the plurality of conveying wheels 25. The plurality of conveying wheels 25 are connected by a first belt drive 26. A driving part for driving one of the conveying wheels 25 to rotate is provided on the frame 2. The driving part includes a rotating shaft 28 rotatably connected to the frame 2. A driven gear 29 is installed on the rotating shaft 28 through a one-way bearing. Among them, a rack 30 meshing with the driven gear 29 is fixedly connected to the L-shaped rod 27. A second belt drive 31 is connected between the rotating shaft 28 and one of the conveying wheels 25;

[0056] In the bundling of cardboard, to enhance stability, workers often bundle two parallel tie straps on the cardboard. Thus, when the L-shaped rod 27 moves downward, the L-shaped rod 27 drives the rack 30 to move synchronously, and the rack 30 drives the driven gear 29 to rotate. Since the driven gear 29 is installed on the rotating shaft 28 through a one-way bearing, the driven gear 29 will idle on the rotating shaft 28, and the rotating shaft 28 will not rotate. When the pressing plate 5 drives the L-shaped rod 27 to move upward and reset, the rack 30 will drive the driven gear 29 to reverse. At this time, the driven gear 29 will drive the second belt drive 31 to reverse through the rotating shaft 28, and the second belt drive 31 will drive one of the conveyor wheels 25 to rotate. One of the conveyor wheels 25 will drive a plurality of conveyor wheels 25 to rotate synchronously through a plurality of first belt drives 26, and the plurality of conveyor wheels 25 will drive the cardboard on the bundling machine 1 to move a certain distance, so that it is not necessary to manually move the cardboard to tie the second tie strap, and the bundling is more convenient.

[0057] For this automatic cardboard bundling device of the carton, when bundling cardboard, place the cardboard on the operating table of the bundling machine 1. First, drive the pressing plate 5 to move downward through the telescopic device 4, and the four pressing plates 5 will press on the cardboard. Then, complete a bundling operation through the bundling machine 1, and then drive the pressing plate 5 to move upward and reset through the telescopic device 4. During the bundling process of the cardboard, it is evenly compacted through the pressing plate 5, so that the bundling effect of the cardboard can be significantly improved, and it is not easy to appear loose;

[0058] When the pressing plate 5 moves upward and resets, the pressing plate 5 will compress the elastic telescopic airbag 9, and the elastic telescopic airbag 9 will discharge the internal air through the exhaust pipe 11. When the pressing plate 5 moves downward to press the cardboard, the four pressing plates 5 will drive the eight baffles 6 to block around the cardboard, so that the paper scraps generated by the extrusion of the cardboard will not directly splash rapidly into the surrounding environment, reducing the pollution of the paper scraps to the surrounding environment. And the pressing plate 5 will also stretch the elastic telescopic airbag 9, and the elastic telescopic airbag 9 will suck the gas in the inner cavity 34 of the baffle 6 through the suction pipe 10. The cavity 34 will suck the paper scraps generated by the extrusion of the cardboard into the cavity 34 of the baffle 6 through the dust suction groove 8 and filter them through the filter plate 33, so as to prevent the paper scraps from polluting the surrounding environment and the bundling machine 1. On the one hand, it reduces the harm to the staff caused by the paper scraps, and on the other hand, it can reduce the situation that the bundling machine 1 is stuck and damaged due to excessive dust;

[0059] When the pressing plate 5 moves downward, the pressing plate 5 will drive the L-shaped rod 27 to move downward synchronously. When the pressing plate 5 moves downward to the limit position, the L-shaped rod 27 will press against the switch 32, and the switch 32 will open the solenoid valve in the suction pipe 10, and the suction pipe 10 will start to suck air from the inner cavity 34 of the baffle 6. That is, after the cardboard is pressed by the pressing plate 5, the dust suction groove 8 will start to suck the paper scraps. And at the moment when the solenoid valve is opened, the elastic telescopic airbag 9 will instantly suck air from the suction pipe 10 under the action of the elastic force, so that the dust suction groove 8 has a higher dust suction effect;

[0060] In the bundling of cardboard, in order to improve stability, workers often bundle two parallel tie straps on the cardboard. Thus, when the L-shaped rod 27 moves downward, the L-shaped rod 27 drives the rack 30 to move synchronously. The rack 30 drives the driven gear 29 to rotate. Since the driven gear 29 is installed on the rotating shaft 28 through a one-way bearing, the driven gear 29 will idle on the rotating shaft 28 and the rotating shaft 28 will not rotate. When the pressing plate 5 drives the L-shaped rod 27 to move upward and reset, the rack 30 will drive the driven gear 29 to reverse. At this time, the driven gear 29 will drive the second belt drive 31 to reverse through the rotating shaft 28. The second belt drive 31 will drive one of the conveyor wheels 25 to rotate. One of the conveyor wheels 25 will drive a plurality of conveyor wheels 25 to rotate synchronously through a plurality of first belt drives 26. The plurality of conveyor wheels 25 will drive the cardboard on the bundling machine 1 to move a certain distance, so that there is no need to manually move the cardboard to tie the second tie strap, and the bundling is more convenient.

[0061] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
