Description

Technical Field

[0001] This invention relates to the technical field of corrugated cardboard processing, and particularly to a flute type switching machine. Background Technology

[0002] The typical structure of corrugated cardboard is a clever combination of face paper and corrugated paper. From a structural mechanics perspective, its shape is very scientific and reasonable. The core of corrugated cardboard is the flute, so the shape, type, and combination of the flutes have a great influence on the properties of the corrugated paper. The types of corrugated cardboard depend on the combination of various flute types; different combination methods result in different physical properties of the corrugated cardboard.

[0003] Typically, a complete sheet of multi-layer corrugated cardboard is formed by gluing single-layer corrugated paper from a single-facer through the gluing device of a flute changer, followed by bonding multiple single-layer corrugated sheets into the double-facer of the flute changer under pressure. Most traditional flute changers on the market use a vertical cutter and a scissor cutter structure. The vertical cutter cuts paper vertically, and most are installed at the entrance of the double-facer. When feeding paper, the operator's arm will reach into the entrance of the double-facer, placing the arm directly under the blade, where the teeth on the blade can easily scratch the arm. Furthermore, because the vertical cutter is perpendicular to the direction of the cardboard's movement, it cannot apply maximum pressure shear force to the cardboard (insufficient tension at the shear point), resulting in uneven cuts. In some cases, it may even fail to cut high-strength cardboard due to its greater toughness.

[0004] The slitting cutter has a double-bar winding paper cutting structure. In simple terms, the blade and an auxiliary rod wind the paper into an S-shape. By winding, the tension of the paperboard is increased, which increases the tension between the blade and the paper. The blade can then apply a larger shearing force to the paper. The slitting cutter makes up for the insufficient shearing tension of the vertical cutter. However, due to the additional auxiliary winding structure, it still occupies a relatively large space. For some production lines with tight spaces, the slitting cutter cannot be well adapted. Furthermore, because the slitting cutter occupies a large space, it needs to be installed outside the equipment, which takes up the operator's operating space, affects the operator's paper feeding, and also poses a risk of the blade scratching the operator.

[0005] Traditional corrugated sheet changers mostly use a blow-type paper feeding mechanism. This involves a round or square tube filled with compressed air from an air compressor, with small holes drilled in the tube. The paper is placed on the air tube, and the compressed air pressure blows the paper into the inlet of the double-sided device. This paper feeding method is affected by many factors, such as insufficient air pressure from the air compressor, excessive paper weight which prevents the air pressure from blowing, and excessive paper moisture causing overlap and blockage. Therefore, the effect is relatively unstable and random. Sometimes the paper feeding is successful, and sometimes it fails. The paper fed into the inlet has obvious wrinkles, and due to the limitations of blow-type paper feeding, the feeding distance is short, often resulting in paper blockage at the inlet.

[0006] Therefore, it is necessary to improve the rafter switching machine to address the aforementioned shortcomings. Summary of the Invention

[0007] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a corrugation switching machine. The paper cutting mechanism is modified so that it can be hidden inside the machine base, avoiding the risk of scratching the operator during manual operation. The rotary operation mode can coordinate the stress of each component to cut the corrugated board faster and with better flatness. The adsorption paper feeding method can ensure the stability of paper feeding.

[0008] To achieve the above objectives, the present invention provides a rafter switching machine, comprising:

[0009] A gluing device includes a gluing machine base, on which at least one set of gluing mechanisms, a face paper mechanism, and a rotary paper cutting mechanism matching the number of gluing mechanisms are provided. The rotary paper cutting mechanism includes a rotating base and a cutter rotatably connected to the rotating base. The rotating base is fixed to the discharge port of the gluing machine base, and the cutter is placed inside the gluing machine base. The rotating base separates the cutter from the discharge port of the gluing machine base to achieve a hidden setting of the cutter.

[0010] The double-sided device includes an adhesive applicator adjacent to it. The double-sided device comprises a double-sided base, on which an adsorption paper feeding mechanism and a hot-pressing mechanism are sequentially mounted. The adsorption paper feeding mechanism includes an adsorption main seat fixed to the double-sided base, on which an adsorption component and a conveying component are mounted. The adsorption component is located within the conveying component, which has a first adsorption port that cooperates with the adsorption component. The rotary paper cutting mechanism occupies minimal space and can be concealed within the equipment, solving the problem of insufficient tension on the cardboard. The paper cutting success rate reaches 100%, easily cutting even high-quality cardboard with clean, tear-free cuts. It also solves the problem of difficult paper feeding, allowing paper feeding operations even at low speeds, providing sufficient safety for operators.

[0011] Furthermore, the rotary paper cutting mechanism also includes a cylinder fixed to the gluing machine base, a first fixed support shaft, and a guide roller movably sleeved on the first fixed support shaft. The rotating base includes clamp-type oilless bearings movably sleeved at both ends of the first fixed support shaft. The clamp-type oilless bearings are respectively connected to the cutter and the cylinder. The two ends of the guide roller are movably connected to the first fixed support shaft through connecting bearings. The cutter includes a blade body and a cutting edge, and the cutting edge is a toothed cutting edge. This allows the cutter to rotate rotatably, and the combination with the guide roller increases the tension of the corrugated paper, resulting in a better overall cutting effect.

[0012] Furthermore, the clamp-type oilless bearing includes an oilless inner ring sleeved on both ends of the first fixed support shaft and an oilless outer ring movably connected to the outer peripheral surface of the oilless inner ring. The outer end face of the oilless outer ring extends outward to form a first protrusion and a second protrusion, which are distributed on both sides of the oilless outer ring. The clamp-type bearing allows for rotation with the cutter and features a simple structure, convenient installation and disassembly, and quick maintenance.

[0013] Furthermore, the oil-free outer ring includes a left clamping block and a right clamping block that are spliced ​​together. The first protrusion is located on the left clamping block, and the second protrusion is located on the right clamping block. The position of the second protrusion is slightly higher than the position of the first protrusion relative to the horizontal line. The staggered arrangement of the first and second protrusions can increase the rotation range of the cutter, thereby increasing the cutting force of the cutter and resulting in a better cutting effect.

[0014] Furthermore, the rotating base also includes a guide shaft, with both ends fixed to the first protrusion. Multiple sets of guide blocks are evenly distributed on the guide shaft, each guide block having an arc structure that is close to the outer circumferential surface of the paper guide roller. The blade is fixedly connected to the guide blocks. This ensures the direction of the cutter's movement and prevents misalignment. The fixed connection between the blade and the guide holes increases the stability of the cutter's operation.

[0015] Furthermore, the gluing mechanism includes a first paper guide roller group, a second paper guide roller group, a gluing roller group, and a glue tank. The first paper guide roller group includes a first paper roller and a second paper roller that cooperate with each other. The second paper guide roller group includes a third paper roller and a fourth paper roller that cooperate with each other. The gluing roller group includes a scraping roller and a gluing roller that are pressed tightly together. The gluing roller is in close contact with the fourth paper roller. The lower end face of the gluing roller is suspended in the glue tank. The face paper mechanism includes a fifth paper roller, a sixth paper roller, and a seventh paper roller arranged in sequence. The diameter of the sixth paper roller is larger than that of the fifth paper roller and the seventh paper roller.

[0016] Furthermore, the adsorption main seat includes a second fixed support shaft, a third fixed support shaft, a first positioning plate, and a second positioning plate symmetrically arranged with respect to the first positioning plate. The first and second positioning plates are each provided with a first mounting hole, a second mounting hole, and a third mounting hole. The second and third fixed support shafts are respectively fixedly connected to the first and second positioning plates through connecting plates. The axes of the second fixed support shaft, the two third mounting holes, and the third fixed support shaft are on the same horizontal line.

[0017] Furthermore, the adsorption assembly includes a suction fan, a suction pipe, and a suction box. The suction fan is externally mounted on the double-sided base and communicates with the suction pipe via a connecting pipe. The suction pipe passes through the second mounting hole and communicates with the suction box. The two ends of the suction box are fixedly connected to the first positioning plate and the second positioning plate, respectively. Multiple rows of equidistantly arranged suction ports are provided on the suction box, with adjacent rows of suction ports staggered. This enables adsorption-type paper feeding, greatly improving paper feeding efficiency and success rate, and is unaffected by paper weight or humidity. Personnel only need to place the paper on the adsorption feeding mechanism for automatic paper feeding.

[0018] Furthermore, the conveying assembly includes a conveying support, a conveying belt, a main drive roller, a secondary drive roller, and a conveying motor fixed on the conveying support.

[0019] The conveying support is fixedly mounted on the second positioning plate. Both the first and second positioning plates are provided with a first bearing assembly for connecting the auxiliary drive roller. The end of the auxiliary drive roller passes through the third mounting hole and connects to the first bearing assembly to achieve free rotation. Adjusting seats are fixedly connected to the side edges of both the first and second positioning plates. Each adjusting seat has an adjusting screw, the end of which is fixedly connected to the bearing seat. The third mounting hole is an elongated adjusting hole.

[0020] The two ends of the main drive roller are respectively installed in the first mounting hole through the provided second bearing group. The main drive roller is connected to the conveyor motor. The conveyor belt is sleeved on the main drive roller and the auxiliary drive roller to achieve rotation.

[0021] Furthermore, the conveyor belt is tightly fitted onto the outer peripheral surfaces of the main drive roller and the auxiliary drive roller, completely covering the suction box. The first suction port is located on the conveyor belt, and the number and arrangement of the first suction ports match the suction port. The surface of the conveyor belt is provided with multiple sets of evenly arranged conveyor teeth. This allows for adjustable position of the auxiliary drive roller, which can be adjusted according to actual conditions to accommodate different types of paper. The cooperation between the suction port and the first suction port improves the suction effect and ensures normal paper transport.

[0022] Furthermore, the hot pressing mechanism includes: two sets of cooperating pressing rollers, a pressing motor connected to the pressing rollers, and a baking assembly. The pressing rollers are adjacent to the adsorption assembly, and the baking assembly is located behind the pressing rollers to bake the corrugated material after pressing.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The invention employs a rotary paper cutting mechanism, which not only overcomes the problem of low paper cutting success rate of vertical cutters but also solves the problem of large space occupation of scissor cutters. The rotary paper cutting mechanism used in this invention occupies a small space and can be hidden inside the equipment. After the paper is glued, it passes directly through the paper cutting mechanism. The distance between the two contact points of the paper is very close, and the closer the two contact points are, the greater the tension. This solves the problem of insufficient tension on the cardboard, and the paper cutting success rate can reach 100%. Even high-quality cardboard can be easily cut, and the cut is flat, beautiful and tear-free.

[0025] 2. This invention employs an adsorption-type paper feeding mechanism. Compared to existing pneumatic blowing methods, this invention significantly improves paper feeding efficiency and success rate, and is unaffected by paper weight or humidity. Operators simply place the paper on the adsorption feeding mechanism for automatic feeding, solving the problem of difficult paper feeding. Paper feeding can also be performed at low speeds, providing sufficient safety for operators. The negative pressure adsorption paper feeding mechanism is compact, with a maximum thickness of only 4 cm, making it compatible with over 95% of equipment on the market. It is easy to install and occupies little space.

[0026] 3. The equipment has a compact structure, occupies little space, is stable and reliable with a low failure rate, and can be applied to over 95% of production lines on the market. It fully utilizes the compact internal space of the equipment, adapts to various types of cardboard, and reduces production losses caused by paper changing and feeding to 0.5% or even zero. It also eliminates dangerous paper feeding and feeding behaviors by operators at the source, minimizing the risks associated with paper cutting and feeding. Attached Figure Description

[0039] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0041] Furthermore, if the embodiments of the present invention involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0042] Please see Figures 1 to 9 An embodiment of the present invention provides a rhombus type switching machine, comprising:

[0043] The gluing device 1 includes a gluing base 11, on which at least one set of gluing mechanism, face paper mechanism, and rotary paper cutting mechanism 2 matching the number of gluing mechanisms are provided; the double-sided device 3 is arranged adjacent to the gluing device 1 and the double-sided device 3, which includes a double-sided base 31, on which a suction paper feeding mechanism 4 and a hot pressing mechanism are arranged in sequence. It should be noted that the number of gluing mechanism, rotary paper cutting mechanism 2 and suction paper feeding mechanism 4 is the same. For example, in this embodiment, the gluing mechanism, rotary paper cutting mechanism 2 and suction paper feeding mechanism 4 are all set to two sets. The number of these mechanisms can be determined according to the number of layers of corrugated paper 5 to be processed.

[0044] Please see Figures 2 to 4 In this embodiment, the rotary paper cutting mechanism 2 includes a rotating base and a cutter 22 rotatably connected to the rotating base. The cutter 22 in this embodiment includes a blade 221 and a cutting edge 222. The cutting edge 222 is a toothed cutting edge, but it can also be changed to other types of cutters 22 according to actual conditions, which will not be repeated here. The rotating base is fixed to the discharge port of the gluing machine base 11, and the cutter 22 is placed inside the gluing machine base 11. Specifically, the rotary paper cutting mechanism 2 also includes a cylinder 23 fixed to the gluing machine base 11, a first fixed support shaft 24, and a guide roller 25 movably sleeved on the first fixed support shaft 24. The two ends of the guide roller 25 are movably connected to the first fixed support shaft 24 through connecting bearings. When the guide roller 25 is in operation, it can cooperate with the operation of the gluing mechanism to realize the output of paper. The guide roller 25 is close to the gluing mechanism, and the paper is simultaneously subjected to the force from the gluing mechanism and the guide roller 25, so the paper will be tightened, and the cutting effect of the cutter 22 when it rotates downward is better.

[0045] To achieve the rotatability and concealed design of the cutter 22, the rotating base includes clamp-type oilless bearings 26 movably sleeved at both ends of the first fixed support shaft 24. The clamp-type oilless bearings 26 are connected to the cutter 22 and the cylinder 23, respectively. Each clamp-type oilless bearing 26 includes an oilless inner ring 261 sleeved at both ends of the first fixed support shaft 24 and an oilless outer ring movably connected to the outer circumferential surface of the oilless inner ring 261. The oilless inner ring 261 and the oilless outer ring together form the clamp-type oilless bearing 26 that allows the cutter 22 to rotate. Furthermore, to enhance the rotational force of the cutter 22, the outer end of the oilless outer ring extends outward to form a first convex shape. Block 262 and second protrusion 263 are distributed on both sides of the oil-free outer ring. Specifically, the oil-free outer ring includes a first clamping block 264 and a second clamping block 265 spliced ​​together. The first protrusion 262 is located on the first clamping block 264, and the second protrusion 263 is located on the second clamping block 265. The position of the second protrusion 263 is slightly higher than the position of the first protrusion (262) relative to the horizontal line. The height of the first protrusion 262 and the second protrusion 263 is adjusted so that the output point of the cylinder 23 and the force point of the cutter 22 are at different heights, thus increasing the rotatability of the cutter 22. The angle of the cutter 22 increases its vertical working range, further enhancing the paper cutting effect. In the initial state, the cutter 22 is completely placed inside the gluing base 11, with the blade 222 facing inward. Furthermore, due to the use of cutters 22 and cylinders 23 at different heights, the blade 222 is angled to the discharge port of the gluing base 11, concealing it within the base. This prevents the operator from touching the blade 222 during paper changing or removal, thus avoiding scratches. Additionally, it prevents the cutter 22 from derailing or becoming misaligned during rotation. To prevent accidents and reduce the contact area between the cutter 22 and the operator, the rotating base in this embodiment also includes a guide shaft 27. The two ends of the guide shaft 27 are fixed to the first protrusion 262. Multiple sets of guide blocks 28 are evenly distributed on the guide shaft 27. The blade 221 of the cutter 22 is fixedly connected to the guide block 28. The guide block 28 has an arc structure that is close to the outer peripheral surface of the guide roller 25. The blade 221 is fixedly connected to the guide block 28. Furthermore, by placing the guide shaft 27 between the cutter 22 and the discharge port, the cutter 22 can be further separated, ensuring that the operator will not be scratched by the cutter 22.

[0046] In this embodiment, the gluing mechanism includes a first paper guide roller group, a second paper guide roller group, a gluing roller group, and a glue tank 12. The first paper guide roller group includes a first paper roller 13 and a second paper roller 14 that cooperate with each other. The second paper guide roller group includes a third paper roller 15 and a fourth paper roller 16 that cooperate with each other. The gluing roller group includes a scraping roller 17 and a gluing roller 18 that are pressed together. The gluing roller 18 is in close contact with the fourth paper roller 16. The lower end face of the gluing roller 18 is suspended in the glue tank 12, so that the glue in the glue tank 12 can adhere to the surface of the gluing roller 18. The face paper mechanism includes a fifth paper roller 19, a sixth paper roller 191, and a seventh paper roller 192 arranged in sequence. The diameter of the sixth paper roller 191 is larger than that of the fifth paper roller 19 and the seventh paper roller 192.

[0047] Please see Figures 5 to 9 The adsorption paper feeding mechanism 4 in this embodiment includes an adsorption main seat fixed to the double-sided machine base 31. The adsorption main seat is provided with an adsorption component and a conveying component. The adsorption component is located inside the conveying component. The conveying component is provided with a first adsorption port 50 that cooperates with the adsorption component. The adsorption main seat includes a second fixed support shaft 411, a third fixed support shaft 412, a first positioning plate 42, and a second positioning plate 43 symmetrically arranged with the first positioning plate 42. The first positioning plate 42 and the second positioning plate 43 are each provided with a first mounting hole 44, a second mounting hole 45, and a third mounting hole 46. The second fixed support shaft 411 and the third fixed support shaft 412 are respectively fixedly connected to the first positioning plate 42 and the second positioning plate 43 through a connecting plate 47. The axes of the second fixed support shaft 411, the two third mounting holes 46, and the third fixed support shaft 412 are on the same horizontal line. The adsorption main seat can be fixed to the double-sided machine base 31 by the second fixed support shaft 411 and the third fixed support shaft 412, and the length of the second fixed support shaft 411 and the third fixed support shaft 412 can be adjusted as needed to adapt to the main unit of different sizes, making it more practical.

[0048] The adsorption assembly includes a suction fan 48, a suction pipe 481, and a suction box 482. The suction fan 48 is externally mounted on the double-sided base 31 and communicates with the suction pipe 481 through a connecting pipe. The suction pipe 481 passes through the second mounting hole 45 and communicates with the suction box 482. The two ends of the suction box 482 are fixedly connected to the first positioning plate 42 and the second positioning plate 43, respectively. Multiple rows of equidistantly arranged suction ports 483 are provided on the suction box 482, with adjacent rows of suction ports 483 staggered. This staggered arrangement of the suction ports 483 fills the suction gaps in the previous row, resulting in a more uniform suction distribution throughout the suction box 482. When feeding paper, this makes the suction force on the paper more uniform, resulting in a flatter surface, enhanced heat-pressing bonding, and reduced defect rate.

[0049] The conveying assembly includes a conveying support 49, a conveying belt 491, a main drive roller 492, a secondary drive roller 493, and a conveying motor 494 fixed on the conveying support 49. The conveying support 49 is fixed on the second positioning plate 43. Both the first positioning plate 42 and the second positioning plate 43 are provided with a first bearing assembly 495 for connecting the secondary drive roller 493. The end of the secondary drive roller 493 passes through the third mounting hole 46 and is connected to the first bearing assembly 495 to achieve free rotation. The side edges of the first positioning plate 42 and the side edges of the second positioning plate 43 are fixedly connected with adjusting seats 431. The adjusting seat 431 is provided with an adjusting screw 432. The end of the adjusting screw 432 is fixedly connected to the bearing seat. The third mounting hole 46 is an elongated adjusting hole. The adjustment screw 432 and the elongated third mounting hole 46 cooperate to realize the left and right position adjustment of the secondary drive roller 493, which can be used to transport papers of different sizes.

[0050] The two ends of the main drive roller 492 are respectively installed in the first mounting hole 44 through the provided second bearing group 496, and the main drive roller 492 is connected to the conveying motor 494;

[0051] The conveyor belt 491 is tightly sleeved on the outer peripheral surfaces of the main drive roller 492 and the auxiliary drive roller 493, and completely covers the suction box 482. The first suction port 50 is provided on the conveyor belt 491, and the number and arrangement of the first suction ports 50 match the suction port 483. The surface of the conveyor belt 491 is provided with multiple sets of evenly arranged conveyor teeth 51, which are arc teeth.

[0052] The hot pressing mechanism includes: two sets of cooperating pressing rollers 52, a pressing motor connected to the pressing rollers 52, and a baking component 53. The pressing rollers 52 are adjacent to the adsorption component, and the baking component 53 is located behind the pressing rollers 52 to receive and bake the corrugated material after pressing.

[0053] The working principle of this invention is as follows: each group of gluing mechanisms provides forward movement power to the corrugated paper 5, and the fourth paper roller 16 and the gluing roller 18 cooperate to apply glue to the corrugated paper 5. At this time, the gluing roller 18 provides upward support force to the corrugated paper 5, and the corrugated paper 5 drives the guide roller 25 to rotate. At the same time, the rotation of the guide roller 25 will also generate a downward reaction force on the corrugated paper 5. Under the cooperation of such support force and reaction force, the corrugated paper 5 will be tightened. When the production line operator receives the order instruction from the management center that it needs to change from five-layer cardboard to three-layer cardboard, the operator operates the cylinder 23 lifting button of the counter-rotating paper cutting mechanism 2. The cylinder 23 is lifted, driving the cutter 22. Under the action of the guide shaft 27, the cutter 22 rotates downward along the arc direction of the guide roller 25 to cut the paper. When the management center order indicates that the number of layers of corrugated paper 5 is increased or that it is changed from A-flute to B-flute, the operator only needs to turn on the suction fan 48 of the corrugated paper 5, overlap the paper on the upper plane of the mechanism, and the suction port 483 on the mechanism and the output tooth surface of the special conveyor belt will firmly adsorb and fix the single-sided corrugated paper 5. Then, by controlling the operation of the conveyor motor 494, the conveyor belt 491 is started to convey the paper at a uniform speed, safely and smoothly conveying the paper into the bonding inlet of the double-sided machine. Then, the pressure roller 52 presses the corrugated paper 5 together, and the baking component 53 heats and bakes to assist in the forming.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
