Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and more specifically to a floating tension-adjustable conveyor line. Background Technology

[0002] In the manufacturing process of sanitary products such as sanitary napkins and panty liners, conveyor lines are used to transport material strips (e.g., lint-free paper) to the appropriate locations for pressing and cutting to form the corresponding sanitary products. The conveyor line consists of multiple sets of conveyor rollers. The material strip roll is placed on the conveyor rollers at the input end, and then the material strip is stretched and pulled between the multiple sets of conveyor rollers for transport. A crucial aspect of the transport process is ensuring that the material strip does not undergo severe deformation, which could lead to substandard products. The key to solving this problem lies in precisely adjusting the tension of the material strip during transport.

[0003] To address the aforementioned issues, existing technology discloses a sanitary napkin absorbent paper forming and processing equipment (publication number CN206230578U). This equipment includes a frame, and, according to the conveying direction of the absorbent paper strip, a material storage device, a tension regulator, a deviation corrector, a roller-type cutter, and a bonding device. A strip anti-deviation device is provided between the tension regulator and the deviation corrector. This device consists of two limiting guide rods, one end of which is fixed to the frame, and the other end is a cantilever end with hooks that can act on the edge of the absorbent paper strip. The force direction of the hooks on one limiting guide rod is opposite to that on the other. This technology adds a strip anti-deviation device, using two limiting guide rods with hooks placed on the left and right sides of the strip to achieve limiting, thereby ensuring that the absorbent paper does not exhibit serpentine swaying, deviation, or deviation before cutting.

[0004] However, the existing technology still has the following technical problems:

[0005] 1. The above production line is not suitable for easily deformable material belts such as cleanroom paper. The inventors discovered that in actual production, due to the long length of the entire production line and its long-term operation, when the material belt is too tight, it is easily stretched and deformed, resulting in the material belt width not meeting the standard. When the material belt is too loose, it is extremely easy for the material belt to move on the conveyor rollers. If a blocking and limiting method such as a hook is used at this time, the material belt is very easy to be scratched and deformed by the obstruction after deviating from the edge. At the same time, the long-term scraping of the material belt will also cause more dust in the workshop.

[0006] 2. The above-mentioned production line is only suitable for shorter production lines and not for production lines with longer production processes or composite production lines capable of producing multiple hygiene products. The inventors observed in actual production that when the entire production line is long, in order to save space, the material feed area is often placed perpendicular to the subsequent areas. Therefore, the precision at the material feed end is particularly important. However, the existing technology is not designed for this situation, and material deformation may still occur. Summary of the Invention

[0007] The present invention aims to provide a floating tension-adjustable conveyor line to solve the problem that the edge of the conveyor belt is easily scratched and deformed by obstructions during the correction process in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A floating tension-adjustable conveyor line includes a conveyor roller group, a tension adjustment mechanism, and a rotary correction mechanism arranged sequentially along the conveying direction. The conveyor roller group includes an active roller driven to rotate by a power component.

[0010] The tension adjustment mechanism includes a fixed base, a limiting rod, and a floating component rotatably connected to the fixed base. The floating component includes a swing arm and a floating shaft that are fixedly connected to each other perpendicularly. Limiting rods are provided above the left and right arms of the swing arm, and counterweights are also provided on the left and right arms of the swing arm. The middle part of the swing arm is rotatably connected to the fixed base, and a rotary sensor for detecting its rotation is connected to the middle part of the swing arm.

[0011] The rotary correction mechanism includes a correction seat, a strip detector, and a correction roller assembly. The correction roller assembly includes a roller base and a correction roller shaft located at the bottom of the roller base. The correction seat is equipped with a rotary drive component, and the power output shaft of the rotary drive component is fixedly connected to the roller base. The strip detector is located on one or both sides of the strip, and the detection end of the strip detector faces the direction of the strip.

[0012] Beneficial effects:

[0013] 1. This technology sets up a tension adjustment mechanism between the drive roller and the rotary correction mechanism, which can adjust the tension before the rotary correction mechanism, thereby preventing the material belt from being too tight and deformed; at the same time, it can also prevent the material belt from being too loose and causing the material belt to deviate on the roller.

[0014] 2. Due to the tension adjustment mechanism, most of the deviations caused by the material belt being too loose can be resolved. However, this technology still has a rigorously designed rotary correction mechanism. If the material belt detector detects that the material belt is still deviating, the rotary drive can drive the correction roller to rotate, thereby achieving the correction function.

[0015] 3. Counterweights are installed on both the left and right arms of the pendulum. The counterweights can be used to adjust the balance and proportion of the two sides of the pendulum, which facilitates more precise monitoring and prevents the pendulum from swinging randomly.

[0016] In summary, compared with existing technologies, this technology not only reduces the problem of strip deformation and deviation by adjusting the tension before the rotation correction mechanism, but also rotates and corrects the strip by driving the strip stretched at the bottom of the correction roller shaft through the rotation drive component during the correction process. No obstruction is required to limit the sides of the strip, which makes it less likely to cause damage and deformation to the sides of the strip, thus further improving product quality.

[0017] Preferably, as an improvement, a mounting plate is detachably connected to the outer wall of the fixed base, and the rotary sensor is detachably connected to the mounting plate.

[0018] Beneficial effects: Since the installation of the rotary sensor requires screwing bolts from the inside of the mounting base outwards, compared to directly mounting the rotary sensor on the mounting base, this technology mounts the rotary sensor on the mounting plate and then fixes the mounting plate to the outer wall of the mounting base with bolts from the front, which is more convenient for disassembly. Especially when it is necessary to replace or repair the rotary sensor, it is not necessary to remove the entire base, which is more convenient.

[0019] Preferably, as an improvement, the fixing seat is an inverted U-shaped structure, the fixing seat includes an L-shaped seat and an outer plate detachably connected to the L-shaped seat; the mounting plate is detachably connected to the outer plate; the swing arm is rotatably connected inside the L-shaped seat.

[0020] Beneficial effects: This structure ensures a more compact and centralized installation and connection structure for the swing arm and rotary sensor; by setting the L-shaped base and outer plate as a separate structure, the outer plate can be removed when the internal structure needs to be inspected, which is more convenient.

[0021] Preferably, as an improvement, the L-shaped base is provided with a rotating shaft, the swing arm is fixed on the rotating shaft, the end of the rotating shaft extends outward and is keyed to a driving gear; the rotating shaft of the rotary sensor is provided with a driven gear that meshes with the driving gear; the inner side of the outer plate is provided with a dust cover, the lower end of the dust cover extends outward and is fixedly connected to the mounting plate; the rotary sensor is located on the upper part of the mounting plate.

[0022] Beneficial effects: The connection between the lever and the rotary sensor is achieved by using gears, which allows the rotary sensor to be eccentrically positioned on the upper part of the mounting plate; the lower part of the mounting plate is used to fix the dust cover, making the overall installation more compact.

[0023] Preferably, as an improvement, it also includes a controller, which is electrically connected to the rotary sensor, the power component, the belt detector, and the rotary drive.

[0024] Beneficial effects: Using the controller to receive signals from the encoder to control the motor to increase or decrease its speed is more convenient and intelligent.

[0025] Preferably, as an improvement, it also includes an input area and a processing area arranged perpendicular to the input area, wherein the conveying roller group, tension adjustment mechanism and rotation correction mechanism are all arranged in the input area; the processing area includes a steering roller group, a drive roller and a tension adjustment mechanism arranged sequentially along the conveying direction; the top of the input area is provided with an output port of the material belt, and the top of the processing area is provided with an input port of the material belt.

[0026] Beneficial effects: Separating and vertically setting the input and processing areas allows for a more centralized layout and reduces the horizontal footprint of the factory. A tension adjustment mechanism is also installed at the drive roller in the processing area, which enables a second tension adjustment of the material belt, further improving product quality and preventing deformation.

[0027] Preferably, as an improvement, the input area also includes a collection roller assembly, which includes a fixed mounting frame, a movable mounting frame, and a telescopic component for driving the movable mounting frame to swing. Multiple rollers are rotatably mounted on both the fixed mounting frame and the movable mounting frame. The fixed mounting frame and the movable mounting frame are arranged in a figure-eight shape.

[0028] Beneficial effects: The movable mounting frame can be swung by the telescopic component to achieve the required angle adjustment; the material strip is wound back and forth on the roller from bottom to top; by setting a collection roller group in front of the drive roller, more material strip can be stored in a limited space.

[0036] The following detailed description illustrates the specific implementation method:

[0037] The reference numerals in the accompanying drawings include: input area 1, drive roller 11, auxiliary roller 12, frame box 13, processing area 2, material belt 3, fixed seat 4, L-shaped seat 41, outer plate 42, tension adjustment mechanism 5, floating shaft 51, support shaft 52, rotating shaft 53, drive gear 531, counterweight 54, limit rod 55, swing rod 56, mounting plate 6, arc-shaped waist hole 61, encoder 7, driven gear 71, dust cover 8, mounting ear 81, correction seat 9, roller seat 91, correction roller shaft 92, infrared sensor 10, guide roller 111, steering roller 112, fixed frame 113, fixed mounting frame 121, movable mounting frame 122, roller shaft 123, telescopic component 124.

[0038] Example 1

[0039] The basics are as follows: Figure 1-3 As shown, the floating tension regulating conveyor line includes an input area 1. In this embodiment, the material belt 3 is a dust-free paper as an example for illustration. The input area 1 includes a frame box 13 and a conveying roller group, a tension regulating mechanism 5 and a rotation correction mechanism arranged sequentially on the inner wall of the frame box 13 along the conveying direction.

[0040] like Figure 1 As shown, the conveyor roller assembly includes a drive roller 11 driven by a power component and auxiliary rollers 12 located to the left and below the drive roller 11. The power component is a motor, which is bolted to the inner wall of the frame housing 13 via a mounting base at its end. The auxiliary roller 12 has an L-shaped mounting base at its end. One end of the mounting base is columnar, passing through the auxiliary roller 12, allowing it to rotate freely on the mounting base. The other end of the mounting base is elongated and has a slotted hole. Bolts are inserted into the slotted hole to fix it to the inner wall of the frame housing 13, and the slotted hole allows for a small range of adjustment of the installation position. The lint-free paper passes under the auxiliary roller 12 on the left side onto the drive roller 11 and is positioned around it. Then, it is pulled from the lower auxiliary roller 12 to the tension adjustment mechanism 5. An auxiliary roller 12 is also provided between the tension adjustment mechanism 5 and the rotation correction mechanism, and its installation method is the same as above.

[0041] Combination Figure 2 and Figure 3As shown, the tension adjustment mechanism 5 includes a fixed base 4 and a floating component rotatably connected to the fixed base 4; the floating component includes a vertically fixed rocker arm 56 and a floating shaft 51. Specifically, the middle of one end of the floating shaft 51 near the inner wall of the frame box 13 protrudes outward to form a connecting shaft, and the end of the connecting shaft is set as a stepped shaft; the end of the rocker arm 56 is provided with a through hole, and the connecting shaft is inserted into the through hole and pressed against the stepped shaft. The middle of the connecting shaft is axially provided with a threaded hole, and the rocker arm 56 is pressed against and fixed at the bolt head and the stepped part of the shaft by inserting bolts and washers.

[0042] like Figure 3 As shown, the fixed base 4 includes an L-shaped base 41 and an outer plate 42. The outer plate 42 and the L-shaped base 41 are separate structures, and the outer plate 42 is fixed to the top plate of the L-shaped base 41 by bolts, so that the fixed base 4 forms an inverted U-shaped structure. The left arm of the L-shaped base 41 is fixed to the inner wall of the frame box 13 by bolts or welding. A support shaft 52 is bolted to the L-shaped base 41. A rotating shaft 53 is rotatably sleeved inside the support shaft 52. The rotating shaft 53 passes through the through hole in the middle of the swing rod 56, and the two are keyed together, so that the swing rod 56 can rotate freely with the rotating shaft 53. A baffle for limiting the swing rod 56 is also provided on the right side of the rotating shaft 53. The end of the rotating shaft 53 extends outward and is keyed to the drive gear 531. Both arms of the swing arm 56 have horizontally arranged slotted holes. Counterweights 54 are bolted to these slots, allowing the position of the counterweights 54 to be adjusted left and right, thus regulating the weight distribution on both sides. To limit the swing arm 56, the top wall of the mounting base 4 has two threaded holes. Limiting rods 55 are threaded into these holes, limiting the maximum swing height of the swing arm 56.

[0043] A mounting plate 6 is bolted to the outer side of the outer plate 42. The mounting plate 6 is circular and has arc-shaped waist holes 61 on both sides. The outer plate 42 has threaded holes corresponding to the arc-shaped waist holes 61. The bolts pass vertically through the arc-shaped waist holes 61 towards the inner wall of the frame box 13 to achieve threaded fixation between the mounting plate 6 and the outer arm of the fixed seat 4. A rotary sensor, specifically an encoder 7 in this embodiment, is mounted on the mounting plate 6. The rotating shaft of the encoder 7 extends into the inner side of the outer arm of the fixed seat 4 and is connected to a driven gear 71. The driven gear 71 meshes with the driving gear 531. A dust cover 8 is also provided on the inner side of the outer plate 42. The dust cover 8 has a through hole for the central shaft to pass through. The dust cover 8 is used to cover the driving gear 531 and the driven gear 71 to prevent dust. The lower end of the dust cover 8 extends outward and bends upward to form a mounting ear 81. The mounting ear 81 is fixed to the mounting plate 6 by screws. The encoder 7 and the mounting plate 6 are installed in the following way: the mounting plate 6 has three through holes and the encoder 7 has threaded holes. Screws are inserted from the inside of the fixing base 4 toward the encoder 7 to achieve threaded fixation between the two. In this technology, the encoder 7 is installed on the upper part of the mounting plate 6, which can avoid gears and facilitate disassembly.

[0044] Rotary correction mechanisms include, for example Figure 1 The guide seat 9, the belt detector, and the guide roller assembly are shown. The guide seat 9 is fixedly connected to the inner wall of the frame housing 13 by bolts. The guide roller assembly includes a roller base 91 and two guide roller shafts 92 located at the bottom of the roller base 91. The guide roller shafts 92 are arranged perpendicular to the inner wall of the frame housing 13, and both ends of the guide roller shafts 92 are rotatably connected to the roller base 91. The guide seat 9 is provided with a rotary drive component, and the power output shaft of the rotary drive component is fixedly connected to the roller base 91. In this embodiment, the rotary drive component is a motor. The detection end of the belt detector is located on the outer edge of the belt 3. The belt detector can be an infrared sensor 10 or a contact sensor. This embodiment takes the infrared sensor 10 as an example for explanation. Its installation method is as follows: An L-shaped mounting bracket is fixed to the right side of the correction seat 9 by screws. The horizontal arm of the L-shaped mounting bracket is horizontally installed on the outer wall of the correction seat 9. The vertical arm of the L-shaped mounting bracket is vertically set towards the inner wall of the frame box 13. The infrared sensor 10 is installed on the inner side of the vertical arm, so that the detection end of the infrared sensor 10 faces the direction of the belt 3. When the belt 3 shifts outward, the infrared light at the detection end is blocked, and the receiving end cannot receive the infrared signal. At this time, after the controller receives the signal, it controls the rotary drive to drive the roller seat 91 to rotate until the belt 3 leaves the detection area of ​​the infrared sensor 10 and then stops rotating.

[0045] This technology also includes a controller, which is electrically connected to the encoder 7, the power component (motor), the material belt detector (infrared sensor 10), and the rotary drive component (motor). The controller receives signals from the encoder 7 to control the motor to increase or decrease its speed. The controller can also receive signals from the material belt detector to control the rotary drive component to drive the correction roller 92 to rotate and achieve correction. The controller is a PLC or a microcontroller; in this embodiment, it is a PLC.

[0046] In summary, this technology can adjust the tension once before the rotary correction mechanism in the input area 1, avoiding the material belt 3 in front of the rotary correction mechanism from becoming too tight or too loose and shifting, thus preventing deformation and further improving product quality.

[0047] In use, the material belt 3 is pulled onto the conveyor line, and the counterweights 54 on the two arms of the swing arm 56 are adjusted. During conveying, the material belt 3 is conveyed by the drive roller 11 and the auxiliary rollers 12 on both sides. When the material belt 3 is too taut, the floating shaft 51 is lifted by the material belt 3, i.e. Figure 2 When the left side of the swing arm 56 is raised, the central shaft 53 of the swing arm 56 rotates, which in turn drives the drive gear 531 to rotate. The driven gear 71 on the encoder 7 then rotates, and the encoder 7 converts the displacement into an electrical signal. Upon receiving the electrical signal, the controller controls the motor to reduce its speed, thereby reducing the speed of the drive roller 11 to alleviate tension and prevent the material belt 3 from being stretched and deformed. When the material belt 3 is too loose, the floating shaft 51 will descend, i.e. Figure 2 The left side of the central swing arm 56 swings downward. Similarly, the drive gear 531 drives the driven gear 71 on the encoder 7 to rotate. The encoder 7 converts the displacement into an electrical signal. After receiving the electrical signal, the controller controls the motor to increase its speed, which in turn increases the speed of the drive roller 11 to speed up the conveying of the material belt 3 and prevent the material belt 3 from shifting in front of the rotation correction mechanism due to looseness, thus greatly reducing the occurrence of displacement.

[0048] If a few displacements still occur during the above process, the rotary correction mechanism can promptly correct them. During use, if the infrared sensor 10 detects that the edge of the conveyor belt 3 has moved outwards into the detection area (outwards here refers to moving towards...), the mechanism will correct the situation. Figure 1 (As the worker moves in the direction they are standing), the controller receives a signal from the infrared sensor 10 and controls the rotary drive to drive the roller seat 91, causing the correction roller shaft 92 to rotate. This, in turn, fine-tunes the material belt 3 stretched on the correction roller assembly, achieving correction. Compared to existing technologies, the material belt 3 will not come into contact with the limiting item and deform during the entire correction process. In addition, to prevent slippage during the conveying process, a rubber layer can be installed on all rollers.

[0049] Example 2

[0050] like Figure 4 , 5 As shown in Figure 6, the difference between this embodiment and Embodiment 1 is that it also includes a processing area 2 perpendicular to the input area 1, which conveys the material belt 3 from the input area 1 to the processing area 2. This arrangement ensures the centralization of the factory layout and reduces the width requirement of the factory floor space. The top of the frame box 13 in the input area 1 is provided with an output port for the material belt 3, and a guide roller 111 is provided there. In other embodiments besides this one, the distance between the input area 1 and the processing area 2 can be used as a pedestrian walkway.

[0051] Combination Figure 6As shown, processing area 2 includes a processing box and a set of guide rollers 112, a drive roller 11, and a tension adjustment mechanism 5 arranged sequentially along the conveying direction of the processing box. The top of the processing box has an input port for the material belt 3, and a guide roller 111 is also located there. The specific structure of the tension adjustment mechanism 5 is the same as in embodiment 1; an auxiliary roller 12 is respectively arranged in front of and behind the tension adjustment mechanism 5, and its installation method is also the same as in embodiment 1. The set of guide rollers 112 includes a fixed frame 113, guide rollers 111, and guide rollers 112. The fixed frame 113 is fixed to the inner wall of the processing box by bolts. The guide rollers 111 are rotatably installed between the two arms of the fixed frame 113, and the guide rollers 111 include two upper guide rollers 111 and one lower guide roller 111, which can be selected as needed. In this embodiment, the material belt 3 is mainly driven along the bottom of the two upper guide rollers 111. The steering roller 112 is inclined with the left side lower and the right side higher. Its lower left end is fixed to the inner wall of the processing box by bolts or welding, and its higher right end is fixed to the top wall of the processing box by bolts or welding.

[0052] In use, the material belt 3 is pulled from the material belt 3 output port at the top of the input area 1 to the material belt 3 input port and enters the processing area 2, such as... Figure 6 As shown, the material belt 3 enters the steering roller 112 through the bottom of the two upper guide rollers 111, achieving a 90-degree turn, and then enters the drive roller 11, which is also driven by a motor. This technology can perform a second tension adjustment on the material belt 3 in front of the drive roller 11 in the processing area 2. The adjustment method is the same as in Embodiment 1. When the material belt 3 is too tight, the floating shaft 51 is lifted by the material belt 3, and the driven gear 71 on the encoder 7 rotates accordingly. The encoder 7 converts the displacement into an electrical signal. After receiving the electrical signal, the controller controls the motor to reduce its speed, thereby reducing the speed of the drive roller 11 to relieve the tension and prevent the material belt 3 from being stretched and deformed. When the material belt 3 is too loose, the floating shaft 51 will descend. Similarly, the drive gear 531 drives the driven gear 71 on the encoder 7 to rotate. The encoder 7 converts the displacement into an electrical signal. After receiving the electrical signal, the controller controls the motor to increase its speed, thereby increasing the speed of the drive roller 11 to speed up the conveying of the material belt 3 and prevent the material belt 3 from shifting in front of the drive roller 11 due to looseness, further ensuring the quality of the product.

[0053] Example 3

[0054] like Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the input area 1 also includes a material collecting roller assembly, which includes a fixed mounting frame 121, a movable mounting frame 122, and roller shafts 123; the fixed mounting frame and the movable mounting frame 122 are arranged in a V-shape. Multiple roller shafts 123 are rotatably connected between the two arms of the fixed mounting frame 121, arranged sequentially from top to bottom, and the inner arm is fixed to the frame box 13 by bolts or welding.

[0055] Multiple rollers 123 arranged sequentially from top to bottom are rotatably connected between the two arms of the movable mounting frame 122. One arm is rotatably connected to the inner wall of the frame housing 13 via a shaft, and the other arm is rotatably connected to the outer wall of the frame housing 13 (i.e., the beam at the top of the door side) via a shaft. A fixed shaft is also provided near the top between the two arms. This technology uses a telescopic member 124 hinged to the frame housing 13, with the power output shaft of the telescopic member 124 sleeved on the fixed shaft. The telescopic member 124 can be any of a pneumatic cylinder or a hydraulic cylinder; in this embodiment, it is a hydraulic cylinder.

[0056] In use, the movable mounting bracket 122 can be swung by a hydraulic cylinder to achieve the required angle adjustment; while the material strip 3 is wound back and forth on the roller shaft 123 from bottom to top. By setting a collecting roller group in front of the drive roller 11, more material strip 3 can be stored in a limited space.

[0057] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
