Description

Technical Field

[0001] This application relates to the technical field of corrugated paper production equipment, and in particular to a corrugated paper conveying system for continuous production. Background Technology

[0002] Currently, corrugated base paper includes corrugated core paper and corrugated facing paper. Corrugated core paper is the raw material paper used to form the corrugated core of corrugated cardboard. It is processed by a corrugating machine, where corrugated rolls heated to 160-180℃ corrugate the core paper to form corrugated paper. Corrugated facing paper is the paper that covers the corrugated core paper, and it plays a crucial role in the appearance, strength, hardness, and lubricity of the subsequent corrugated paper.

[0003] The production process of corrugated paper includes pulp mixing, pulp pressing and filtration, temperature and humidity treatment, and winding. Throughout the production process, the corrugated paper needs to be continuously conveyed. After pulp pressing and filtration, there is significant friction between the paper and the conveyor belt due to the presence of moisture. As a result, when the paper is transferred from the temperature and humidity treatment stage to the winding stage, the friction between the paper and the conveyor belt is high under the traction of the winding rollers. Direct separation of the paper and the conveyor belt along the conveyor belt's direction can easily cause tearing, affecting the quality of subsequent paper production. Therefore, this process needs improvement. Summary of the Invention

[0004] In order to facilitate the separation between the face paper and the conveyor belt during continuous conveying, reduce tearing caused by high friction between the face paper and the conveyor belt, and improve the production quality of subsequent corrugated base paper, this application provides a corrugated paper conveying system for continuous production.

[0005] The corrugated paper conveying system for continuous production provided in this application adopts the following technical solution:

[0006] A continuous production corrugated paper conveying system includes a filter pressing mechanism, a temperature and humidity treatment mechanism, and a winding mechanism. The filter pressing mechanism includes a filter press and a first conveyor belt. The temperature and humidity treatment mechanism includes a temperature and humidity treatment device and a second conveyor belt. The winding mechanism includes a winding machine and a third conveyor belt. A separation component is provided between the second conveyor belt and the third conveyor belt. The separation component includes a frame that is lifted and disposed between the second conveyor belt and the third conveyor belt, clamping rollers disposed on the frame, a lifting component for adjusting the lifting of the frame, and an auxiliary roller disposed at one end of the second conveyor belt near the third conveyor belt. Two sets of clamping rollers are provided, and a gap is left between the two sets of clamping rollers for the raw paper to pass through. The height of the auxiliary roller is higher than the height of the second conveyor belt.

[0007] By adopting the above technical solution, during the production of raw paper, when the raw paper is transported close to the third conveyor belt, the auxiliary rollers lift the height of the raw paper, causing it to separate from the third conveyor belt as it approaches. This reduces cracks caused by lateral stretching directly with the conveyor belt during traction, thus improving the finished quality of the raw paper. At the same time, the clamping rollers further clamp and flatten the raw paper as it is transported from the second conveyor belt to the third conveyor belt, reducing surface burrs caused when the raw paper separates from the second conveyor belt, thereby improving the surface quality of the raw paper when used as face paper.

[0008] Optionally, the separation assembly further includes a flattening roller disposed on the side of the clamping roller near the second conveyor belt, a wetting element disposed on the side of the clamping roller near the second conveyor belt, and a drying element disposed on the side of the third conveyor belt. The flattening roller is provided in two sets, and the two sets of flattening rollers are arranged inclined to the axis of rotation of the clamping roller. Each set of flattening rollers includes two flattening rollers arranged in parallel and spaced apart, and the two flattening rollers in each set clamp the raw paper.

[0009] By adopting the above technical solution, when the raw paper enters between the two clamping rollers, the wetting component first wets the raw paper, and then the flattening roller clamps the raw paper. Since the flattening roller is inclined, it tends to stretch the raw paper when clamping it, thereby reducing wrinkles caused by pressure filtration and flattening the surface of the raw paper. The flattened raw paper is then clamped and pressed between the two clamping rollers, making it less likely for the wrinkled parts to shrink back after being flattened. At the same time, the drying component dries the raw paper after it is clamped and flattened, so that the raw paper remains stable after being flattened. This ensures that the raw paper after correction and flattening always maintains a smooth surface and improves the surface quality of the raw paper.

[0010] The surface quality of the raw paper is treated during the lifting process to reduce adhesion between the raw paper and the conveyor belt while improving the surface quality of the raw paper.

[0011] Optionally, a correction ring is sleeved on the outer peripheral wall of the auxiliary roller. There are two sets of correction rings, and the two sets of correction rings are arranged opposite each other. The outer diameter of the side of the two sets of correction rings that are close to each other is narrower than the outer diameter of the side that is far away from each other. The auxiliary roller is also provided with an adjusting component for simultaneously adjusting the position of the two correction rings.

[0012] By adopting the above technical solution, the setting of the correction rings and the adjustment component that simultaneously adjusts the two correction rings ensures that the paper is stably centered when it passes through the end of the second conveyor belt, preventing it from shifting. This achieves stable centered conveying of the paper. Furthermore, the correction rings are set in a mutually movable and close-to-each-ring configuration, and the adjustment component allows for simultaneous adjustment of both rings, ensuring that the paper remains centered throughout the transport process. This eliminates the need for technicians to adjust the two correction rings individually, reducing operational steps.

[0013] Optionally, the adjusting component includes an adjusting screw mounted on the auxiliary roller, the correcting rings being threaded onto the adjusting screw, the adjusting screw having symmetrically arranged external threads with opposite threads and the same pitch, and two correcting rings being symmetrically arranged at both ends of the adjusting screw.

[0014] By adopting the above technical solution, when technicians need to adjust the position of the correction rings, they rotate the adjusting screw to make the two correction rings slide on the auxiliary roller. Since the correction rings are slidably set on the auxiliary roller, the sliding direction of the correction rings is limited. At the same time, since the two ends of the adjusting screw have external threads with opposite threads and the same pitch, the correction rings move closer or further away synchronously while the adjusting screw is rotating. This ensures that the two correction rings always remain symmetrical along the length of the second conveyor belt, thus keeping the paper in the center during conveying, reducing the offset during paper conveying that causes edge folding during subsequent winding, and adapting to the correction operation of paper of different widths, thereby improving the adaptability of the device.

[0015] Optionally, the wetting component includes a wetting cylinder mounted on the frame, and the drying component includes a drying cylinder mounted on the frame. The wetting cylinder has a wetting groove that is inclined toward the direction of the second conveyor belt. The drying cylinder has a drying groove that is inclined toward the direction of the third conveyor belt. An atomizing nozzle is connected inside the wetting cylinder, and the atomizing nozzle is connected to a water source. Both the wetting cylinder and the drying cylinder are equipped with a mixing component.

[0016] By adopting the above technical solution, when the base paper is being conveyed, the atomizing nozzle sprays water mist into the wetting cylinder. In order to achieve uniform wetting of the base paper, the mixing component mixes the water mist with air evenly, so that the water mist sprayed from the wetting tank is uniform and achieves uniform wetting of the base paper.

[0017] At the same time, after the paper is flattened, hot air is sprayed out from the drying chamber to dry the flattened paper.

[0018] The mixing element installed in the drying cylinder and the wetting cylinder mixes water mist with air and hot air with air evenly, so as to achieve uniform wetting and drying of the base paper during technical transport.

[0019] Optionally, the mixing component includes a mixing cylinder rotatably disposed inside the wetting cylinder / drying cylinder, the mixing cylinder being coaxially arranged with the wetting cylinder / drying cylinder, and mixing blades being fixedly connected inside the mixing cylinder. Multiple air vents are densely distributed on the outer peripheral wall of the mixing cylinder. The frame is also provided with an air supply component for supplying air into the mixing cylinder, and the frame is also provided with a drive component for synchronously driving the mixing cylinder and the clamping roller.

[0020] By adopting the above technical solution, when wetting is required, the atomizing nozzle sprays water mist into the wetting cylinder. Then, the mixing cylinder rotates, which drives the mixing blades to rotate, so that the air and water mist in the wetting cylinder are mixed evenly. This reduces the water droplets that fall when the water mist is sprayed directly out through the nozzle, which would cause uneven humidity in the base paper and thus affect the subsequent flattening effect.

[0021] Meanwhile, during the drying process, the mixing blades rotate, mixing the hot air entering the drying cylinder with the air, reducing uneven temperature of the hot air sprayed from the drying tank that could cause paper curling or wrinkling, thereby further improving the production quality of the base paper.

[0022] Optionally, the driving component includes a first driving gear fixed to the shaft of the clamping roller, and a first driven gear fixedly connected to the shaft of the mixing cylinder, wherein the first driving gear and the first driven gear mesh with each other.

[0023] By adopting the above technical solution, when the clamping roller rotates to convey and flatten the raw paper, the first drive gear rotates, which drives the second drive gear to rotate, thereby driving the mixing cylinder to rotate. This achieves the conveying and flattening of the raw paper and the control of temperature uniformity in the wetting / drying cylinder, saving energy and simplifying operation.

[0024] Optionally, a sealing plate is slidably disposed on the wetting cylinder, the sealing plate movably sealing the wetting tank; a sealing plate is disposed on the drying cylinder, the sealing plate movably sealing the drying tank; two sets of sealing plates are provided, and the two sets of sealing plates are arranged opposite to each other and move closer together; two sets of sealing plates are provided, and the two sets of sealing plates are arranged opposite to each other and move closer together; the frame is also provided with an adjusting component for simultaneously adjusting the sealing plate and the sealing plate.

[0025] By adopting the above technical solution, since the production specifications of base paper for different purposes are also different, the width of the base paper is also different. Therefore, when conveying base paper of different widths, the required width for drying and wetting is also different. Therefore, by adjusting the sealing plate and the blocking plate by setting the adjustment components, the effective opening width of the wetting tank and the drying tank can be adjusted to adapt to base paper of different widths and improve the adaptability of the device.

[0026] The adjustable components simultaneously adjust the sealing plate and the blocking plate, ensuring that the widths of the wetting tank and the drying tank always correspond. This reduces errors that occur when adjusting the wetting tank and the drying tank separately, thus reducing over-drying or insufficient drying, and consequently reducing warping or wrinkles.

[0027] Optionally, the adjusting component includes a sealing rod threaded through two sealing plates and a sealing rod threaded through two sealing plates. The two sealing plates are symmetrically arranged at both ends of the sealing rod, and the two sealing plates are symmetrically arranged at both ends of the sealing rod. Rotating wheels are coaxially fixedly connected to both the sealing rod and the sealing rod, and a transmission belt drives the two sets of rotating wheels together.

[0028] By adopting the above technical solution, when it is necessary to adjust the opening width of the wetting tank and drying tank according to the different widths of the base paper, the technician can rotate the adjusting sealing rod / blocking rod, so that one set of rotating wheels rotates, and under the action of the transmission belt, drives the other set of rotating wheels to rotate the window, thereby realizing the synchronous rotation drive of the sealing rod and the blocking rod, and thus realizing the synchronous adjustment of the sealing plate and the blocking plate. The operation is simple.

[0029] Optionally, the frame is provided with a fixed frame, and there are two sets of fixed frames, with each set of fixed frames corresponding to one of the two sets of flattening rollers. An adjusting rod is threaded through each of the two sets of fixed frames, and an adjusting wheel is provided on the adjusting rod. The adjusting wheel is located between the two sets of rotating wheels and is connected to both sets of rotating wheels in a transmission manner.

[0030] By adopting the above technical solution, when wetting, flattening and drying base paper of different widths, the technicians adjust the rotating wheel, which drives the adjusting wheel to rotate, thereby driving the adjusting rod to rotate, and thus realizes the adjustment of the gap between the two sets of flattening rollers. This achieves multi-width adaptability for wetting, drying and flattening, and improves the adaptability range of the entire conveying system.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. By setting auxiliary rollers, correction rings and clamping rollers, the raw paper is assisted in conveying and correcting during the raw paper conveying process, so that the raw paper maintains a gap with the second conveyor belt when it is conveyed to the end side of the second conveyor belt, reducing the tearing between the raw paper and the conveyor belt. At the same time, the clamping rollers flatten the raw paper, reducing the burrs generated when the raw paper separates from the conveyor belt.

[0033] 2. By using a set of wetting components, flattening rollers, and drying components, the paper is wetted and flattened before being clamped and conveyed by the clamping rollers, reducing wrinkles generated during production. At the same time, the paper is dried after flattening, which further addresses the wrinkle recovery problem during subsequent winding and improves the surface quality of the paper.

[0034] 3. By using a mixing element installed inside the wetting / drying cylinder, moisture and air, and hot air are kept mixed evenly, thereby improving the uniformity of wetting and drying of the base paper, reducing edge curling or wrinkles caused by uneven wetting or drying, and improving the surface quality of the base paper.

[0040] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0041] This application discloses a corrugated paper conveying system for continuous production. (Refer to...) Figure 1A continuous production corrugated paper conveying system includes a filter press mechanism 1, a temperature and humidity treatment mechanism 2, and a winding mechanism 3 arranged sequentially along the conveying direction. The filter press mechanism 1 includes a filter press device 11 fixed on the ground and a first conveyor belt 12 located at the outlet of the filter press. The temperature and humidity treatment mechanism 2 includes a temperature and humidity treatment device 21 fixed on the ground and a second conveyor belt 22. The winding mechanism 3 includes a winding device 31 fixed on the ground with its axis horizontally aligned and a third conveyor belt 32. In order to facilitate the separation of the raw paper from the second conveyor belt 22 when the winding mechanism 3 pulls the raw paper and to improve the surface quality of the raw paper when the winding mechanism 3 winds the raw paper, a separation component 4 is also provided between the second conveyor belt 22 and the third conveyor belt 32.

[0042] Reference Figure 1 and Figure 2 The separation component 4 is provided on the support of the second conveyor belt 22 near the third conveyor belt 32 and the auxiliary roller 41 is rotatably mounted on the support. The auxiliary roller 41 is arranged at a height higher than the second conveyor belt 22 and the arrangement direction of the auxiliary roller 41 is perpendicular to the conveying direction of the raw paper. A correction spring 413 is provided at the rotating shaft of the auxiliary roller 41. In this application, the correction spring 413 is a torsion spring, which provides elastic recovery for the support of the auxiliary roller 41, thereby lifting the raw paper and the second conveyor belt 22 during the raw paper conveying process and providing a certain amount of buffering to reduce the rigid tearing of the raw paper.

[0043] Because the paper will have some elastic fluctuations after being lifted, in order to reduce the paper offset caused by the fluctuations and make it neat during subsequent winding, a correction ring 411 is fitted on the auxiliary roller 41. There are two correction rings 411, which are symmetrically arranged at both ends of the auxiliary roller 41. The correction ring 411 is truncated cone-shaped, and the diameter of the side of the two correction rings 411 that is close to each other is narrower than the diameter of the side that is far away from each other. The correction ring 411 is rotatably mounted on the auxiliary roller 41. When the paper is conveyed from the second conveyor belt 22 to the third conveyor belt 32, the correction ring 411 keeps the paper in the middle position of the second conveyor belt 22, which facilitates the subsequent neat winding operation.

[0044] Since the correction rings 411 are rotatably mounted on the auxiliary roller 41, and different base papers have different widths, the correction rings 411 need to be adjusted in order to perform correction operations on different base papers. An adjusting screw 412 is rotatably connected to the bracket, and two sets of correction rings 411 are symmetrically arranged at both ends of the adjusting screw 412. The two ends of the adjusting screw 412 have external threads with the same pitch but opposite threads. Therefore, when it is necessary to adjust the correction rings 411 according to the width of the base paper, the technician rotates the adjusting screw 412, so that the correction rings 411 slide on the auxiliary roller 41, and the two sets of correction rings 411 move closer and further apart until the width between the two sets of correction rings 411 is consistent with the width of the base paper. At this time, it is convenient to perform correction on base papers of different widths.

[0045] Because it was found in actual production that even if the raw paper was lifted in advance and separated from the second conveyor belt 22, burrs were still easily generated on the bottom side of the raw paper, in order to improve the smoothness of the raw paper surface, the separation component 4 also includes a lifting frame 42 and clamping rollers 44 on the frame 42. There are two sets of clamping rollers 44, and the two sets of clamping rollers 44 are arranged in parallel at intervals in the horizontal direction. The arrangement direction of the clamping rollers 44 is perpendicular to the transport direction of the raw paper, and a gap is left between the two sets of clamping rollers 44 for the raw paper to pass through.

[0046] Before the base paper enters the third conveyor belt 32 for winding, the base paper is flattened again by the clamping rollers 44, thereby improving the smoothness of the base paper surface and improving the quality of the base paper when used as face paper.

[0047] Because the raw paper is prone to folding or wrinkling during the pressing and conveying process, in order to improve the quality of the flattened raw paper, refer to Figure 2 and Figure 3 The separation component 4 also includes a flattening roller 43 located on the side of the clamping roller 44 near the second conveyor belt 22. The rotation axis of the flattening roller 43 is also horizontal, and the rotation axis of the flattening roller 43 is inclined at a certain angle to the rotation axis of the clamping roller 44. There are also two sets of flattening rollers 43. The two sets of flattening rollers 43 are respectively located on the side of the clamping roller 44 near the second conveyor belt 22 and are arranged symmetrically. Each set of flattening rollers 43 includes two flattening rollers 43 arranged parallel to each other in the vertical direction, and the two flattening rollers 43 in each set clamp the edge of the paper.

[0048] Because the flattening roller 43 is arranged at an angle, before the raw paper is fed into the clamping roller 44 for flattening, the rotation of the flattening roller 43 causes the edges of the raw paper to have a tendency to extend outward in a certain direction, thereby achieving pre-flattening of the raw paper, making it less likely for the raw paper to have folds or wrinkles when it enters the clamping roller 44, and further improving the surface quality of the raw paper.

[0049] Furthermore, to improve the flattening effect of folded edges and wrinkles, the separation assembly 4 also includes a wetting component 45 and a drying component 46. The wetting component 45 is located on the frame 42 on the side of the clamping roller 44 near the second conveyor belt 22, and the drying component 46 is located on the frame 42 on the side of the clamping roller 44 near the third conveyor belt 32. The wetting component 45 includes a wetting cylinder 451 on the frame 42, and a wetting groove 452 is formed on the outer peripheral wall of the wetting cylinder 451, with the wetting groove 452 facing the second conveyor belt 32. The conveyor belt 22 is inclined on one side. The wetting cylinder 451 is fixedly connected to an atomizing tube and an atomizing nozzle 453. The atomizing tube is connected to a water source and a fan. The drying component 46 includes a drying cylinder 461 mounted on a frame 42. A drying groove 462 is provided on the outer peripheral wall of the drying cylinder 461. The drying groove 462 is inclined on one side facing the third conveyor belt 32. A drying tube is fixedly connected inside the drying cylinder 461. A hot air nozzle 463 is provided on the drying tube. The drying tube is connected to a hot air source.

[0050] During the process of the raw paper entering the third conveyor belt 32 from the second conveyor belt 22, the wetting element 45 first wets the surface of the raw paper, then the flattening roller 43 flattens the raw paper, then the clamping roller 44 flattens the raw paper, and finally the paper is dried, thereby improving the surface quality treatment effect and efficiency of the raw paper.

[0051] Meanwhile, to ensure uniformity in wetting or drying the surface of the raw paper, both the drying cylinder 461 and the wetting cylinder 451 are equipped with a mixing element. The mixing element includes a mixing cylinder 47 coaxially arranged inside the drying cylinder 461 / wetting cylinder 451. The mixing cylinder 47 covers the drying tube / atomizing tube, and multiple sets of mixing blades 472 are fixedly connected to the inner peripheral wall of the mixing cylinder 47. Multiple sets of air vents 471 are opened on the outer peripheral wall of the mixing cylinder 47. Therefore, when drying or wetting the surface of the raw paper, the mixing cylinder 47 first rotates to fully mix the water mist and air, hot air and air, thereby achieving uniform wetting and drying of the raw paper.

[0052] In order to achieve automatic wetting before the clamping roller 44 clamps and flattens the paper and automatic drying after flattening, the frame 42 is also provided with a drive unit 48 for synchronously rotating the clamping roller 44 and the mixing cylinder 47. The drive unit 48 includes a first driving gear 481 coaxially fixed on the clamping roller 44 and a first driven gear 482 coaxially fixed on the rotating shaft of the mixing cylinder 47. The first driving gear 481 meshes with both first driven gears 482, and a rotating motor is fixedly connected to the rotating shaft of the clamping roller 44.

[0053] As mentioned above, the width of the base paper is uneven. To adapt the surface treatment to the width of the base paper, refer to... Figure 2 , Figure 3 and Figure 4A sealing plate 454 is slidably mounted on the wetting cylinder 451. There are two sets of sealing plates 454, which are arranged opposite to each other and slide in opposite directions. The sealing plates 454 movably seal the wetting tank 452. Similarly, a sealing plate 464 is slidably mounted on the drying cylinder 461. There are two sets of sealing plates 464, which are arranged opposite to each other and slide in opposite directions. The sealing plates 464 movably seal the drying tank 462. Therefore, when processing paper of different widths, the opening width of the wetting tank 452 and the drying tank 462 changes when the technician adjusts the sealing plates 454 and 464, so that the opening width of the wetting tank 452 and the drying tank 462 is adapted to the width of the paper.

[0054] Furthermore, to facilitate the synchronous adjustment of the sealing plate 454 and the sealing plate 464, the frame 42 is also equipped with an adjusting component 49. The adjusting component 49 includes a sealing rod 491 rotatably disposed in the wetting cylinder 451 and a sealing rod 492 rotatably disposed in the drying cylinder 461. Both the sealing rod 491 and the sealing rod 492 adopt the form of a double-ended screw. Both ends of the sealing rod 491 and the sealing rod 492 are provided with external threads of opposite pitch. The two sealing plates 454 are symmetrically arranged at both ends of the sealing rod 491, and the two sealing plates 464 are symmetrically arranged at both ends of the sealing rod 492. At the same time, the frame 42 slides upwards. A fixed frame 495 is provided, and there are two sets of fixed frames 495. The two sets of fixed frames 495 correspond one-to-one with two sets of flattening rollers 43. The flattening rollers 43 are rotatably mounted on the fixed frame 495. An adjusting rod 497 is threaded through the fixed frame 495. The adjusting rod 497 has symmetrically opened external threads with opposite threads and the same pitch. An adjusting motor is fixedly connected to one end of the adjusting rod 497. At the same time, an adjusting wheel 496 is coaxially fixed on the adjusting rod 497. Rotating wheels 494 are fixedly connected to both the sealing rod 492 and the blocking rod 491. A transmission belt 493 is used to drive the rotating wheel 494 and the adjusting wheel 496.

[0055] Thus, when the adjusting motor drives the two fixed frames 495 to move closer to each other, and the two flattening rollers 43 move closer to each other, the adjusting wheel 496 drives the rotating wheel 494 to rotate under the transmission belt 493, thereby realizing the synchronous rotation of the sealing rod 491, the sealing rod 492 and the adjusting rod 497, and realizing the synchronous adjustment of the sealing plate 454, the sealing plate 464 and the flattening roller 43, saving energy and making operation simple.

[0056] The implementation principle of a continuous production corrugated paper conveying system according to an embodiment of this application is as follows:

[0057] When the raw paper is conveyed to the third conveyor belt 32 via the second conveyor belt 22 for packaging and winding, the auxiliary roller 41 is first positioned at a height higher than the second conveyor belt 22. As a result, the auxiliary roller 41 lifts the raw paper, creating a gap between the raw paper and the second conveyor belt 22. This reduces tearing caused by the raw paper directly along the extension direction of the second conveyor belt 22, improving the forming quality during the conveying process. At the same time, the correction ring 411 set on the auxiliary roller 41 corrects the deviation of the raw paper during conveying, improving the winding neatness when it is subsequently conveyed to the winding equipment 31.

[0058] Before the raw paper is fed to the clamping roller 44, the wetting cylinder 451 wets the upper and lower surfaces of the raw paper. Then the raw paper enters between the flattening rollers 43. When the flattening rollers 43 are inclined, the raw paper tends to extend to both sides, so that the folds and wrinkles generated in the pressing and previous steps are flattened during the movement of the raw paper. Then the clamping roller 44 flattens the raw paper. At this time, it is easier to flatten the wetted raw paper. At the same time, the drying cylinder 461 dries the raw paper after flattening, thereby improving the surface smoothness and flatness of the raw paper and improving the forming quality when the raw paper is used as face paper.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
