Description

Technical Field

[0001] This application relates to the field of corrugated paper conveying equipment technology, and in particular to a single-sided corrugated paper upward conveyor and an inclined assembly. Background Technology

[0002] In a corrugated board production line, single-faced corrugated paper enters the overhead conveyor via an upward conveyor and is then pulled by the overhead conveyor to a multi-layer gluing machine to complete the gluing of the corrugated paper. Finally, it is laminated by a double-facer to achieve the production of multi-layer corrugated board.

[0003] Traditional single-face corrugated paper conveyors typically use a single paper output roller design, which is simple in structure. After the corrugated paper is conveyed to a high point, it tends to surge upwards due to inertia, resulting in irregular accumulation of paper on the conveyor bridge. This leads to inconsistent paper distribution during production, with varying density of paper piles. When too little paper is piled on the bridge, the downstream machines accelerate, but the single-facer, busy receiving paper, cannot accelerate, potentially causing the paper to break. Conversely, excessive paper accumulation creates too much resistance when the downstream conveyor pulls the paper, also leading to breakage and creases in the raw paper, affecting the quality of the cardboard. Furthermore, the irregular accumulation causes inaccurate calculations of the paper length by the production management control system, affecting the acceleration and deceleration decisions of downstream equipment, potentially causing paper blockages, breaks, and defective products, ultimately impacting the efficiency of the corrugated cardboard production line. Summary of the Invention

[0004] Given that traditional single-face corrugated paper conveyors generally use a single paper output roller design, the corrugated paper tends to surge upwards after being conveyed to a high point due to inertia. The corrugated paper falling onto the overhead conveyor cannot accumulate in a regular manner, which can easily cause paper blockage, paper breakage, and other problems, affecting the efficiency of the corrugated board production line. This application proposes a traditional single-face corrugated paper conveyor with a double paper output roller design, as well as an incline assembly that includes the single-face corrugated paper conveyor and the overhead conveyor belt group, to solve this problem.

[0005] In the first aspect, this application proposes a single-sided corrugated paper conveyor and adopts the following technical solution.

[0006] A single-sided corrugated paper upper conveyor includes an upper traction assembly, a lower traction assembly, and a main motor assembly.

[0007] The upper traction assembly includes a main traction wheel shaft, an upper traction wheel shaft, a first paper output wheel shaft, and a second paper output wheel shaft. The lower traction assembly includes a first lower traction wheel shaft and a second lower traction wheel shaft. The main motor assembly is connected to the main traction wheel shaft. The main traction wheel shaft is connected to the first lower traction wheel shaft via a first traction belt and to the first paper output wheel shaft via a first paper output belt. The main traction wheel shaft is connected to the upper traction wheel shaft. The upper traction wheel shaft is connected to the second lower traction wheel shaft via a second traction belt and to the second paper output wheel shaft via a second paper output belt.

[0008] Driven by the main motor assembly, the main traction wheel shaft, the first lower traction wheel shaft, and the first paper output wheel shaft rotate in the same direction. The rotation direction of the upper traction wheel shaft is opposite to that of the main traction wheel shaft. The second lower traction wheel shaft and the second paper output wheel shaft rotate in the same direction as the upper traction wheel shaft. The first traction belt and the second traction belt can clamp the single-sided corrugated paper and convey it upwards at an incline to the main traction wheel shaft. After being blocked by the second paper output belt or the first paper output belt, it bends and conveys downwards. The first paper output belt and the second paper output belt can clamp the single-sided corrugated paper and output it downwards at an incline.

[0009] By adopting the above technical solution, the upward conveyor uses a double paper-output wheel design with the first paper-output wheel shaft combined with the second paper-output wheel shaft. After the corrugated paper is conveyed upward to the high point of the main traction wheel shaft, it is bent and conveyed downward after being blocked by the second paper-output belt (the second paper-output belt is set above the first paper-output belt) or the first paper-output belt (the first paper-output belt is set above the second paper-output belt). The single-sided corrugated paper, which is clamped and output downward at an inclination by the first paper-output belt and the second paper-output belt, can fall onto the overpass in a regular manner and accumulate in a regular manner, reducing the probability of paper blockage, paper breakage and other situations, and improving the efficiency of the corrugated board production line.

[0010] In a preferred embodiment of the single-sided corrugated paper conveyor, the second paper output belt is pressed against the upper surface of the main traction wheel shaft, such that the second paper output belt is inclined upward on one side of the main traction wheel shaft and inclined downward on the other side. The upper surface of the main traction wheel shaft is higher than the lower surface of the upper traction wheel shaft, so that the inclined upward section of the second paper output belt continues to be arranged upward after the inclined upward section of the second traction belt. The first traction belt and the second traction belt clamp the single-sided corrugated paper and convey it inclined upward. When it passes the inclined upward section of the second paper output belt and reaches the upper surface of the main traction wheel shaft, it bends downward after being pressed by the second paper output belt and is clamped by the first paper output belt and the inclined downward section of the second paper output belt and conveyed inclined downward.

[0011] By adopting the above technical solution, the single-sided corrugated paper at the lower position is pulled upward and conveyed to the higher point (the upper surface of the main traction wheel shaft). It is then bent downward by the pressure of the second paper output belt and the upper surface of the main traction wheel shaft. Then, it is clamped by the first paper output belt and the inclined downward section of the second paper output belt and conveyed downward at an angle. During this process, the single-sided corrugated paper will not continue to rush upward when it reaches the higher point. The single-sided corrugated paper can turn stably, and the output quality is stable.

[0012] In a preferred embodiment of the single-sided corrugated paper conveyor, the upward tilt angle of the second paper output belt is 10-20° smaller than the upward tilt angle of the second traction belt.

[0013] By adopting the above technical solution, the single-sided corrugated paper first travels upwards at an angle along the second traction belt, and then is slightly pre-bent downwards by the upward-angled section of the second paper output belt, improving the smoothness of subsequent turns. The upward angle here is the angle between the inclined surface and the horizontal plane.

[0014] A preferred embodiment of the single-sided corrugated paper conveyor is that the angle between the upward-sloping section and the downward-sloping section of the second paper output belt is 110~130°.

[0015] By adopting the above technical solution, the single-sided corrugated paper completes the tilting upward to tilting downward along the two sections of the second paper output belt. This tilting angle basically does not produce creases and can complete the tilting efficiently, which is beneficial for bending back and forth into a wave shape on the overpass later.

[0016] A preferred embodiment of the single-sided corrugated paper conveyor is that the linear speeds of the first traction belt, the first paper output belt, the second traction belt, and the second paper output belt are all equal.

[0017] By adopting the above technical solution, the corrugated paper is less likely to slide relative to the traction belt and the paper output belt, and the corrugated paper is also less likely to be torn.

[0018] Secondly, this application also proposes a ramp assembly and adopts the following technical solution.

[0019] An incline assembly includes a single-sided corrugated paper feeder and a bridge conveyor belt assembly disposed below an outlet between a first paper output belt and a second paper output belt.

[0020] The main traction wheel axle is connected to the overhead conveyor belt assembly via an intermediate transmission assembly. Driven by the main motor assembly, the single-sided corrugated paper is output from between the first and second paper output belts at a speed greater than the linear speed of the overhead conveyor belt assembly, causing the single-sided corrugated paper to bend and accumulate back and forth on the overhead conveyor belt assembly.

[0021] By adopting the above technical solution, the speed difference between the output speed of the single-sided corrugated paper from the first and second paper output belts and the output speed of the single-sided corrugated paper on the overhead conveyor belt group is fixed. This makes the single-sided corrugated paper bend and stack back and forth on the overhead conveyor belt group, with a regular stacking shape. The resistance when pulling the corrugated paper is stable, which makes it easy to calculate the length of the corrugated paper stacked on the overhead conveyor through the production management and control system, and to pull the corrugated paper in a timely and accurate manner. It is not easy to cause paper blockage, paper breakage, etc., so that the corrugated board production line has high production efficiency.

[0022] A preferred embodiment of the climbing assembly includes a main shaft, a main drive wheel, a primary pulley, and an upper traction wheel coaxially fixed to the main shaft. The main motor assembly is connected to the main drive wheel. The upper traction wheel is connected in the opposite direction to the upper traction wheel shaft. A first traction belt connects the main shaft and the first lower traction wheel shaft. A first paper output belt connects the main shaft and the first paper output wheel shaft.

[0023] The intermediate transmission assembly has an intermediate shaft, and a primary large wheel and a secondary small wheel coaxially fixed to the intermediate shaft.

[0024] The overhead conveyor belt assembly includes an overhead conveyor drive shaft, an overhead conveyor belt, and an overhead conveyor driven shaft. The overhead conveyor belt is horizontally positioned and connects the overhead conveyor drive shaft and the overhead conveyor driven shaft. The overhead conveyor drive shaft has a spindle and a secondary large pulley fixed on the spindle.

[0025] The diameter of the first-stage small wheel is smaller than that of the first-stage large wheel. The diameter of the first-stage large wheel is larger than that of the second-stage small wheel. The diameter of the second-stage small wheel is smaller than that of the second-stage large wheel. The first-stage small wheels are synchronously connected to the first-stage large wheel, and the second-stage small wheels are synchronously connected to the second-stage large wheel, such that the angular velocity of the mandrel is less than the angular velocity of the main shaft, and the linear velocity of the overhead conveyor belt is less than the linear velocity of the first paper output belt.

[0026] By adopting the above technical solution, the angular velocity of the first-stage small wheel is equal to the angular velocity of the spindle. Since the linear velocities of the first-stage small wheel and the first-stage large wheel are equal, the angular velocity of the first-stage large wheel is less than that of the first-stage small wheel. Since the angular velocity of the first-stage large wheel is equal to that of the second-stage small wheel, the linear velocity of the first-stage large wheel is greater than that of the second-stage small wheel. Since the linear velocity of the second-stage small wheel is equal to that of the second-stage large wheel, the angular velocity of the second-stage small wheel is greater than that of the second-stage large wheel. Therefore, the angular velocity of the spindle = angular velocity of the first-stage small wheel > angular velocity of the first-stage large wheel = angular velocity of the second-stage small wheel > angular velocity of the second-stage large wheel = angular velocity of the spindle. By designing the diameter ratio of the first-stage small wheel and the first-stage large wheel, the diameter ratio of the second-stage small wheel and the second-stage large wheel, the diameter of the main shaft and the mandrel, and the rotational speed of the main motor assembly driving the main shaft, the flow velocity difference of the single-sided corrugated paper on the upper conveyor and the overhead conveyor belt can be designed, so that the single-sided corrugated paper forms a regular wave-like arch and piles up against each other on the overhead conveyor belt.

[0027] A preferred embodiment of the ramp assembly includes a guide plate. The guide plate is inclined downwards, positioned at the end of the first paper output belt, and located above the overhead conveyor belt assembly. The guide plate receives the downwardly output single-sided corrugated paper clamped by the first and second paper output belts, and continues to be inclined downwards to be led out to the overhead conveyor belt assembly.

[0028] By adopting the above technical solution, the guide plate reduces the height difference of the inclined single-sided corrugated paper falling on the overhead conveyor belt group, and controls the waveform arching to a smaller shape.

[0029] A preferred embodiment of the climbing assembly is that the overpass conveyor belt group is horizontally arranged, and the included angle between the guide plate and the overpass conveyor belt group is 150~160°.

[0030] By adopting the above technical solution, a corrugated arch can be easily formed between the lower end of the guide plate and the overhead conveyor belt assembly, and the forward tilt angle of the corrugated arch on the overhead conveyor belt assembly can be easily controlled.

[0031] A preferred embodiment of the climbing assembly is as follows: there is a vertical drop between the lower end of the guide plate and the overhead conveyor belt assembly; single-sided corrugated paper, inclined downwards along the guide plate, falls onto the overhead conveyor belt assembly. Due to the difference between the speed at which the first and second paper output belts clamp and output the single-sided corrugated paper and the speed at which the overhead conveyor belt assembly transports the single-sided corrugated paper, the single-sided corrugated paper between the lower end of the guide plate and the overhead conveyor belt assembly forms a corrugated arch. The corrugated arch tilts forward and continues to move along the overhead conveyor belt assembly. The single-sided corrugated paper after each corrugated arch falls onto the overhead conveyor belt assembly to form the bottom of the corrugated arch. The single-sided corrugated paper between the lower end of the guide plate and the bottom of the corrugated arch reforms the corrugated arch. Under the continuous drive of the main motor assembly, multiple forward-leaning corrugated arches lean against each other and accumulate on the overhead conveyor belt assembly, with the bottom of the corrugated arch between two adjacent corrugated arches.

[0032] By adopting the above technical solution, the speed difference between the output speed of the single-sided corrugated paper from the first and second paper output belts and the output speed of the single-sided corrugated paper on the overhead conveyor belt group is fixed. This makes the single-sided corrugated paper bend and stack back and forth on the overhead conveyor belt group, with a regular stacking shape. The resistance when pulling the corrugated paper is stable, which makes it easy to calculate the length of the corrugated paper stacked on the overhead conveyor through the production management and control system, and to pull the corrugated paper in a timely and accurate manner. It is not easy to cause paper blockage, paper breakage, etc., so that the corrugated board production line has high production efficiency.

[0033] In summary, the single-sided corrugated paper upward conveyor of this application has the following beneficial effects: The upward conveyor adopts a double paper output wheel design with the first paper output wheel shaft combined with the second paper output wheel shaft. After the corrugated paper is conveyed upward to the high point of the main traction wheel shaft, it is bent and conveyed downward after being blocked by the second paper output belt (the second paper output belt is set above the first paper output belt) or the first paper output belt (the first paper output belt is set above the second paper output belt). The single-sided corrugated paper, which is clamped by the first paper output belt and the second paper output belt and outputs downward at an inclination, can fall onto the bridge and accumulate in a regular manner, reducing the probability of paper blockage, paper breakage and other situations, and improving the efficiency of the corrugated board production line.

[0034] The climbing assembly of the present application has the following beneficial effects: By adopting the main motor assembly and through the synchronous belt and chain transmission mechanism, the linkage of the upper traction assembly, the lower traction assembly and the overpass conveyor belt group is realized. The lower traction assembly adopts a double lower traction wheel shaft design. Workers only need to place the single-sided corrugated paper in the middle gap between the two traction belts on the two traction wheel shafts, and the paper can be conveyed to the double paper output wheel shaft of the upper traction assembly, so that the paper can reach the overpass conveyor belt group smoothly and be stacked stably on the overpass conveyor belt group in the same shape, laying a foundation for the production of subsequent multi-layer cardboard. Using this climbing assembly to produce single-sided corrugated paper at high speed, the paper threading is simple, reducing the labor intensity of workers. The multi-component linkage is convenient for control, energy-saving and efficient. The conveyed paper is not prone to phenomena such as breaking or paper jamming, reducing the number of stops, reducing production losses and improving production efficiency.

Detailed Implementation

[0043] The technical solutions in the embodiments are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the following embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Example 1 like Figure 1 A single-sided corrugated paper upper conveyor includes a support 5, and an upper traction assembly 1, a lower traction assembly 2 and a main motor assembly 4 mounted on the support 5.

[0045] The support 5 includes two upper traction vehicle walls 51 arranged symmetrically, and two lower traction vehicle walls 52 arranged symmetrically.

[0046] Combination Figure 1 and Figure 2 The upper traction assembly 1 includes a main traction wheel axle 101, an upper traction wheel axle 102, a first paper output wheel axle 103 and a second paper output wheel axle 104, and two upper carriage wall support ribs 105. These components are parallel to each other, and the two ends of each component are mounted on the two upper traction carriage walls 51. The upper carriage wall support ribs 105 are fixed to the inside of the upper traction carriage walls 51 by screws, which improves the support rigidity of the two upper traction carriage walls 51 for each wheel axle, keeps the wheel axles parallel, and prevents the paper from deviating.

[0047] The lower traction assembly 2 includes a first lower traction wheel axle 21, a second lower traction wheel axle 22, and two lower carriage wall support ribs 23. These components are parallel to each other, and both ends of each component are mounted on the two lower traction carriage walls 52. The lower carriage wall support ribs 23 are fixed to the inside of the lower traction carriage walls 52 by screws, which improves the support rigidity of the two lower traction carriage walls 52 for each wheel axle, so that the first lower traction wheel axle 21 and the second lower traction wheel axle 22, which are mounted with seat bearings, remain parallel on the lower traction carriage walls 52, preventing the paper from slipping.

[0048] refer to Figure 3 The main motor assembly 4 provides the power source for the entire upward conveyor. The main motor assembly 4 consists of a main motor, a synchronous pulley 41, and an adjustable motor mount. The main motor is mounted on the motor mount, which is fixed to the bracket 5. The output shaft of the main motor is fixedly connected to the synchronous pulley 41. The synchronous pulley 41 is connected to the main traction wheel shaft 101 via a drive belt 42.

[0049] refer to Figure 2 The main traction wheel shaft 101 is connected to the first lower traction wheel shaft 21 in the same direction via the first traction belt 106, and to the first paper output wheel shaft 103 in the same direction via the first paper output belt 107. This "connection in the same direction" means that the rotation directions of the two shafts are the same after connection. The first lower traction wheel shaft 21 and the first paper output wheel shaft 103 are located on opposite sides below the main traction wheel shaft 101, with the first lower traction wheel shaft 21 lower than the first paper output wheel shaft 103.

[0050] refer to Figure 4 Specifically, the main traction wheel shaft 101 has a main shaft 1011, and a main drive wheel 1012, a primary pulley 1013, and an upper traction wheel 1014 coaxially fixed to the main shaft 1011. The synchronous pulley 41 of the main motor assembly 4 is connected to the main drive wheel 1012 in the same direction via a drive belt 42. The upper traction wheel 1014 is connected to the upper traction wheel shaft 102 in the opposite direction. The main shaft 1011 is connected to the first lower traction wheel shaft 21 in the same direction via a first traction belt 106. The main shaft 1011 is connected to the first paper output wheel shaft 103 in the same direction via a first paper output belt 107. Multiple first traction belts 106 and multiple first paper output belts 107 are arranged alternately on the main shaft 1011, and under the drive of the main shaft 1011, the first traction belts 106 and the first paper output belts 107 rotate in the same direction.

[0051] The main traction wheel axle 101 is connected to the upper traction wheel axle 102 in a reverse direction. This reverse connection means that the rotation directions of the two are opposite after connection. (Reference) Figure 3One specific structure of this reverse connection is as follows: a pulley 108 is installed on the upper traction vehicle wall 51, and a transmission belt 109 is provided to connect the upper traction wheel 1014 and the pulley 108 in the same direction. The transmission belt 109 can be a double-toothed synchronous belt. One end of the upper traction wheel shaft 102 is fixed with an upper pulley 1021, which abuts against the outside of the transmission belt 109, so that the transmission belt 109 is tensioned. When the main motor assembly 4 is started, the transmission belt 109 can synchronously drive the pulley. The upper traction wheel 1014 and the rotating wheel 108 rotate in the same direction, while the upper traction wheel 1014 and the upper pulley 1021 rotate in opposite directions. If the diameters of the upper traction wheel 1014 and the upper pulley 1021 are equal, then since the linear velocities of the upper traction wheel 1014 and the upper pulley 1021 are equal, their rotational angular velocities are also equal. This means that the rotational angular velocities of the main shaft 1011 of the main traction wheel shaft 101 and the shaft of the upper traction wheel shaft 102 are equal.

[0052] The upper traction wheel axle 102 is connected to the second lower traction wheel axle 22 in the same direction via the second traction belt 110, and is connected to the second paper output wheel axle 104 in the same direction via the second paper output belt 111. The second lower traction wheel axle 22 and the second paper output wheel axle 104 are located on both sides below the upper traction wheel axle 102, and the second lower traction wheel axle 22 is lower than the second paper output wheel axle 104.

[0053] Vertically, the first traction belt 106 is aligned with the second traction belt 110, and the first paper output belt 107 is aligned with the second paper output belt 111. The second traction belt 110 is located above the first traction belt 106, and the second paper output belt 111 is located above the first paper output belt 107.

[0054] The main traction wheel shaft 101 and the upper traction wheel shaft 102 are fixed in position. The first lower traction wheel shaft 21 and the second lower traction wheel shaft 22 are both installed with adjustable tension bearings, which facilitates belt tension adjustment, ensures accurate transmission, and prevents slippage.

[0055] Driven by the main motor assembly 4, the main traction wheel shaft 101, the first lower traction wheel shaft 21, and the first paper output wheel shaft 103 rotate in the same direction. The rotation direction of the upper traction wheel shaft 102 is opposite to that of the main traction wheel shaft 101. The second lower traction wheel shaft 22 and the second paper output wheel shaft 104 rotate in the same direction as the upper traction wheel shaft 102. Single-sided corrugated paper 6 is input between the first traction belt 106 and the second traction belt 110. The first traction belt 106 and the second traction belt 110 clamp the single-sided corrugated paper 6 and convey it upward at an incline to the upper surface of the main shaft 1011 of the main traction wheel shaft 101. After being blocked by the second paper output belt 111, it bends and is conveyed downward. The single-sided corrugated paper 6 is clamped by the first paper output belt 107 and the second paper output belt 111 and output downward at an incline.

[0056] The angle at which the single-sided corrugated paper 6 is tilted upward can be 25~40°, and the angle at which it is tilted downward can be 25~40°. These tilt angles are the angles between the single-sided corrugated paper 6 and the horizontal plane.

[0057] To ensure a stable output speed of the corrugated paper from the upward conveyor, this embodiment limits the first traction belt 106 and the first paper output belt 107. Furthermore, the linear speeds of the first traction belt 106, the first paper output belt 107, the second traction belt 110, and the second paper output belt 111 are all designed to be equal. This ensures that the first traction belt 106 and the second traction belt 110 can clamp the single-sided corrugated paper 6 and transport it upwards at an angle without slipping, and that the first paper output belt 107 and the second paper output belt 111 can clamp the single-sided corrugated paper 6 and transport it downwards at an angle without slipping. Ultimately, the speed and direction of the output corrugated paper are stable. The specific structure for implementing this design is as follows.

[0058] The main shaft 1011 of the main traction wheel axle 101 is provided with multiple annular grooves 1015 at equal intervals, each annular groove 1015 having the same shape and size. The widths of the first traction belt 106, the first paper output belt 107, the second traction belt 110, and the second paper output belt 111 are all equal. The width of the annular groove 1015 is 1.1 to 1.3 times the width of the first traction belt 106; each annular groove 1015 is fitted with one first traction belt 106 or one first paper output belt 107, and the annular groove 1015 limits the first traction belt 106 and the first paper output belt 107, preventing them from shifting during rotation. From one end of the main shaft 1011 to the other, multiple first traction belts 106 and multiple first paper output belts 107 are alternately installed in multiple annular grooves 1015, such that the winding diameter of each first traction belt 106 and each first paper output belt 107 on the main shaft 1011 is equal.

[0059] One end of multiple second traction belts 110 and one end of multiple second paper output belts 111 are staggered and wrapped around the upper traction wheel shaft 102, the other end of multiple second traction belts 110 is wrapped around the second lower traction wheel shaft 22, and the other end of multiple second paper output belts 111 is wrapped around the second paper output wheel shaft 104.

[0060] The upward conveyor also includes guide rods 112, both ends of which are fixed to the two upper traction vehicle walls 51. The guide rods 112 have multiple sets of limiting members. Each set of limiting members includes two vertically downward-pointing vertical rods 1121 located on both sides of the second paper output belt 111. The multiple sets of limiting members limit the movement of multiple second paper output belts 111.

[0061] The upward conveyor also includes two idler rollers 113. One idler roller 113 is mounted on both ends of the two upper traction car walls 51, and the other idler roller 113 is mounted on both ends of the support body 5. Both idler rollers 113 are supported inside and below the first traction belt 106, lifting the first traction belt 106 upward and bringing it closer to the second traction belt 110, thereby strengthening the clamping force of the first traction belt 106 and the second traction belt 110 on the single-sided corrugated paper 6 and reducing the probability of relative slippage.

[0062] The upward conveyor also includes a support inclined plate 117, which is supported below the first paper output belt 107 along the inclined direction of the first paper output belt 107, thereby strengthening the clamping force of the first paper output belt 107 and the second traction belt 110 on the single-sided corrugated paper 6.

[0063] Vertically, the upper traction wheel shaft 102 is higher than the main traction wheel shaft 101, but the upper surface of the main shaft 1011 of the main traction wheel shaft 101 is higher than the lower surface of the upper traction wheel shaft 102. Laterally, the upper traction wheel shaft 102 is closer to the input port of the upper conveyor, and the main traction wheel shaft 101 is closer to the output port of the upper conveyor. One section of the second paper output belt 111 presses against the first paper output belt 107 on the main shaft 1011. The second paper output belt 111 is inclined upwards on one side of the main traction wheel shaft 101 and downwards on the other side. The upward-inclined section of the second paper output belt 111 continues upwards from the upward-inclined second traction belt 110, while the downward-inclined section is located above the first paper output belt 107. At the highest point, the single-sided corrugated paper 6 between the second paper output belt 111 and the first paper output belt 107 is forced to turn by the pressure of the second paper output belt 111, and the turning process is stable. This highest point is located on the upper surface of the main shaft 1011. The upward-sloping section of the second paper output belt 111 can have an angle 10-20° smaller than the upward-sloping angle of the second traction belt 110, to facilitate pre-compression of the single-sided corrugated paper 6 to begin bending downwards. The angle between the upward-sloping and downward-sloping sections of the second paper output belt 111 can be 110-130°, allowing the upward-sloping angle of the single-sided corrugated paper 6 to be 25-40°, and the downward-sloping angle to be 25-40°. These angles are the angles between the single-sided corrugated paper 6 and the horizontal plane. This angle range allows the single-sided corrugated paper 6 to turn smoothly with minimal creases, and also facilitates the bending and stacking of the single-sided corrugated paper 6 in the subsequent overhead conveyor.

[0064] To ensure stable paper output speed, this embodiment designs the following: the winding diameter of each first traction belt 106 on the first lower traction wheel shaft 21 and the main shaft 1011, the winding diameter of each first paper output belt 107 on the first paper output wheel shaft 103 and the main shaft 1011, the winding diameter of each second traction belt 110 on the upper traction wheel shaft 102 and the second lower traction wheel shaft 22, and the winding diameter of each second paper output belt 111 on the upper traction wheel shaft 102 and the second paper output wheel shaft 104 are all equal; simultaneously... Yes, the rotational angular velocities of the main shaft 1011 of the main traction wheel shaft 101 and the shaft of the upper traction wheel shaft 102 are equal; therefore, the linear speeds of the first traction belt 106, the first paper output belt 107, the second traction belt 110, and the second paper output belt 111 are all equal, so that the first traction belt 106 and the second traction belt 110 can clamp the single-sided corrugated paper 6 and convey it upward at an incline, and the first paper output belt 107 and the second paper output belt 111 can clamp the single-sided corrugated paper 6 and output it downward at an incline. The whole process is not prone to relative slippage, and the paper output speed is stable.

[0065] It should be noted that the axle in this embodiment consists of a wheel and an axle. The wheel is fixed on the axle, and the wheel and axle are concentric and can rotate around a common axis. The wheel can be a pulley or a gear. In this embodiment, the traction belt, paper output belt, and drive belt 42 can be a synchronous belt or a belt.

[0066] Example 2 refer to Figure 4 A ramp assembly, including the upward conveyor of Embodiment 1, further including a guide plate 114, an intermediate transmission assembly 115, and reference... Figure 6 It also includes the overpass conveyor belt group 3.

[0067] The guide plate 114 is fixed at both ends to the upper traction vehicle wall 51. The guide plate 114 is inclined downwards at the exit end between the first paper output belt 107 and the second paper output belt 111. The inclination of the guide plate 114 is close to the inclination of the first paper output belt 107, for example, the difference in angle is 0~20°. The guide plate 114 is located above the overhead conveyor belt assembly 3, and the included angle between the guide plate 114 and the overhead conveyor belt assembly 3 can be 150~160°. (Reference) Figure 5 The main motor assembly 4 is started. This angle makes it easy to form a corrugated arch 61 between the lower end of the guide plate 114 and the overhead conveyor belt group 3, and it is easy to control the forward tilt angle of the corrugated arch 61 on the overhead conveyor belt group 3, forming a regular accumulation of paper material and coordinating the production rhythm of the front and rear sections.

[0068] The overhead conveyor belt assembly 3 is mounted on the support 5. The overhead conveyor belt assembly 3 includes an overhead drive pulley axle 31, an overhead belt 32, and an overhead driven pulley axle 33. The overhead belt 32 is horizontally arranged and synchronously connects the overhead drive pulley axle 31 and the overhead driven pulley axle 33.

[0069] The guide plate 114 receives the first paper output belt 107 and the second paper output belt 111, which clamp the downward output single-sided corrugated paper 6, and continues to tilt downward to be output to the overhead conveyor belt group 3.

[0070] The main traction wheel shaft 101 is connected to the bridge drive wheel shaft 31 through the intermediate transmission assembly 115, thereby driving the bridge belt 32 to rotate. The transmission ratio of the intermediate transmission assembly 115 is designed so that the rotational angular velocity of the main traction wheel shaft 101 is several times that of the bridge drive wheel shaft 31, and the linear velocity of the first paper output belt 107 is several times that of the linear velocity of the bridge belt 32. Thus, the corrugated paper output from the outlet between the first paper output belt 107 and the second paper output belt 111 can form arc-shaped arches that stack up on the bridge belt 32, buffering and coordinating the production rhythm, solving the problem of inconsistent speeds between the preceding and following processes, and avoiding machine stoppages due to speed differences.

[0071] The length of the attached diagram for the bridge belt 32 is for illustrative purposes only. In practice, the length of the bridge belt 32 can be made longer to store more corrugated paper.

[0072] The structure in which the main traction wheel axle 101 is connected to the overpass drive wheel axle 31 via the intermediate transmission assembly 115 can be as follows.

[0073] refer to Figure 4 The intermediate transmission assembly 115 has an intermediate shaft 1151, which is combined with Figure 6 The intermediate axle 1151 has a primary large wheel 1152 and a secondary small wheel 1153 coaxially fixed to the intermediate axle 1151. The intermediate axle 1151 passes through the upper tractor wall 51, and the primary large wheel 1152 and the secondary small wheel 1153 are located on both sides of the upper tractor wall 51.

[0074] refer to Figure 6 The overpass drive wheel axle 31 has a spindle 311 and a secondary large wheel 312 fixed on the spindle 311.

[0075] The diameter of the primary pulley 1013 of the main traction wheel axle 101 is smaller than that of the primary pulley 1152. For example, the diameter of the primary pulley 1152 is 2 to 3 times the diameter of the primary pulley 1013, but not limited to this.

[0076] The diameter of the first-stage large wheel 1152 is larger than that of the second-stage small wheel 1153. Since the first-stage large wheel 1152 and the second-stage small wheel 1153 are coaxial and have the same rotational angular velocity, this design is to facilitate the design of a large wheel that is larger than the first-stage small wheel 1013 and a small wheel that is smaller than the second-stage large wheel 1153. Therefore, the ratio of the diameter of the first-stage large wheel 1152 to the diameter of the second-stage small wheel 1153 is not necessarily limited, but the diameter of the first-stage large wheel 1152 can be selected to be 2 to 3 times the diameter of the second-stage small wheel 1153.

[0077] The diameter of the secondary small wheel 1153 is smaller than that of the secondary large wheel 312. For example, the diameter of the secondary large wheel 312 is 3 to 4 times the diameter of the secondary small wheel 1153, but not limited to this.

[0078] The primary small wheel 1013 is synchronously connected to the primary large wheel 1152. The linear velocities of the two are equal, but the angular velocity of the primary large wheel 1152 is less than that of the primary small wheel 1013.

[0079] The first-stage large wheel 1152 and the second-stage small wheel 1153 are coaxial, and their angular velocities are equal.

[0080] The secondary small wheel 1153 is synchronously connected to the secondary large wheel 312. The two have the same linear velocity, but the angular velocity of the secondary large wheel 312 is less than that of the secondary small wheel 1153.

[0081] The above design ensures that the angular velocity of the mandrel 311 is significantly lower than that of the main shaft 1011. The diameters of the mandrel 311 and the main shaft 1011 can be set to be equal, or the diameter of the mandrel 311 can be slightly larger, for example, within 1.5 times the diameter of the main shaft 1011. This makes the linear velocity of the overhead conveyor belt 32 lower than the linear velocity of the first paper output belt 107. By designing the dimensions of these components and controlling the rotational speed of the main motor assembly 4, the speed difference between the first paper output belt 107 and the overhead conveyor belt 32 can be precisely controlled. The overhead conveyor speed, after two-stage deceleration, is much slower than the traction speed, causing the paper to accumulate regularly in the overhead conveyor section, facilitating the production management system's calculation of the accumulated paper length on the overhead conveyor.

[0082] refer to Figure 7 The climbing assembly also includes two tension idler pulleys 116, both mounted on the upper tractor wall 51. The first tension idler pulley 116 rests against the outer side of the connecting strip between the primary pulley 1013 and the primary pulley 1152. (Refer to...) Figure 6 The second tension idler wheel 116 abuts against the outside of the connecting belt between the secondary small wheel 1153 and the secondary large wheel 312, improving the transmission stability and effectiveness of the intermediate transmission assembly 115.

[0083] The operating principle of the climbing assembly is as follows: when the main motor assembly 4 is started, the first traction belt 106 and the second traction belt 110 clamp the single-sided corrugated paper 6 and tilt it upward to the main traction wheel shaft 101. After being blocked by the inverted V-shaped second paper output belt 111, it bends and is conveyed downward. The first paper output belt 107 and the second paper output belt 111 clamp the single-sided corrugated paper 6 and tilt it downward to the guide plate 114. Because there is a vertical drop between the lower end of the guide plate 114 and the overhead conveyor belt group 3, the single-sided corrugated paper 6, which is inclined downward along the guide plate 114, falls onto the overhead conveyor belt group 3. Since the speed at which the first paper output belt 107 and the second paper output belt 111 clamp and output the single-sided corrugated paper 6 is faster than the speed at which the overhead conveyor belt group 3 transports the single-sided corrugated paper 6, the single-sided corrugated paper 6 between the lower end of the guide plate 114 and the overhead conveyor belt group 3 forms a corrugated arch 61. The corrugated arch 61 tilts forward and continues to move with the overhead conveyor belt group 3. The single-sided corrugated paper 6 after each corrugated arch 61 falls onto the overhead conveyor belt group 3 to become the bottom of the corrugated wave 62. The single-sided corrugated paper 6 between the lower end of the guide plate 114 and the bottom of the corrugated wave 62 re-forms the corrugated arch 61. Under the continuous drive of the main motor assembly 4, multiple forward-tilting corrugated arches 61 lean against each other and pile up on the overhead conveyor belt group 3, with the bottom of the corrugated wave 62 between two adjacent corrugated arches 61.

[0084] This application employs a design with upper and lower first paper output rollers 103 and second paper output rollers 104, which allows the corrugated paper to smoothly transition from an upward to a downward tilt, unlike a single paper output roller which might cause it to lurch upwards. This achieves stable and regular paper output, ensuring that the corrugated paper enters the overhead conveyor section at a fixed angle and at the same speed, where it accumulates smoothly. This regular arrangement of corrugated paper allows the production management system to accurately calculate the length of the raw paper accumulated on the overhead conveyor, enabling more precise control of the acceleration and deceleration of single-facers and double-facers. This achieves synchronization of the entire production line's speed, thereby solving the problems of paper blockage and paper breakage, reducing the number of production equipment downtimes, lowering the defect rate, and improving production efficiency.

[0085] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
