Description

Technical Field

[0001] This invention relates to the field of air spring processing technology, and more specifically, to a curtain opening device. Background Technology

[0002] In the manufacturing process of air springs, the air spring fabric layer is a crucial structural component. The production of the air spring fabric layer involves unrolling the calendered fiber fabric, cutting, splicing, and rolling it at specific angles and widths according to production process requirements, thus providing the foundation for subsequent product manufacturing. Due to continuous upgrades, improvements, and innovations in air spring products, the precision requirements for the cutting angles and widths of the air spring fabric are becoming increasingly stringent.

[0003] The opening of small-angle fiber cord fabric is usually achieved by pulling the fabric directly with a pull roller and then using a padding motor to separate the fabric from the padding. The fabric is then fed to the main machine for cutting via a delivery platform. However, the fiber cord fabric used in air springs is thinner than that used in traditional tires, typically between 0.55mm and 1.0mm. This thinner fabric is easily stretched and deformed. Therefore, existing fiber cord opening devices cannot meet the precision requirements of opening and cutting the fiber cord fabric in air springs, easily causing severe fabric stretching, deviation during transport, and wrinkling, affecting subsequent cutting quality and resulting in a high defect rate of the cut fabric. Summary of the Invention

[0004] The main objective of this invention is to provide a curtain opening device to solve the problem that existing fiber curtain opening devices cannot meet the fiber curtain opening requirements in air springs.

[0005] To achieve the above objectives, the present invention provides a curtain opening device, comprising: a material roll support mechanism for placing material formed by curtain fabric and padding fabric; a padding fabric winding mechanism for retrieving the padding fabric; and a peeling roller mechanism, wherein one end of the padding fabric is wound around the padding fabric winding mechanism, and the padding fabric winding mechanism drives the padding fabric to move on the peeling roller mechanism, thereby driving the curtain fabric to move on the peeling roller mechanism. The peeling roller mechanism includes a first peeling component and a second peeling component arranged sequentially along the conveying direction. The material passes through the first peeling component and the second peeling component sequentially. When the material passes through the first peeling component, the curtain fabric and the padding fabric separate. When the curtain fabric and the padding fabric are between the first peeling component and the second peeling component, the curtain fabric and the padding fabric are attached. When the curtain fabric and the padding fabric pass through the second peeling component, the curtain fabric and the padding fabric separate. The padding fabric is then retracted onto the padding fabric winding mechanism.

[0006] Furthermore, the first stripping assembly includes a first conveying roller, a second conveying roller, and a third conveying roller. The second conveying roller is located between the first and third conveying rollers. The first and third conveying rollers form a first conveying track, and the first, second, and third conveying rollers form a second conveying track. The first and second conveying tracks are at least partially offset. When the material passes through the first conveying roller, the curtain and the pad are separated. After the curtain passes through the first conveying track and the pad passes through the second conveying track, the curtain and the pad re-contact and adhere to each other on the third conveying roller.

[0007] Furthermore, the first conveying trajectory is straight, the second conveying trajectory is U-shaped, and the first conveying trajectory is located at the opening of the second conveying trajectory.

[0008] Furthermore, the second peeling assembly includes a fourth conveying roller located at the tail end of the peeling roller mechanism, and a third conveying roller located between the fourth conveying roller and the first conveying roller. When the third conveying roller re-contacts the bonded fabric and padding fabric, their conveying directions are different when they are on the fourth conveying roller, and the fabric and padding fabric separate.

[0009] Furthermore, the second stripping assembly also includes at least one fifth conveying roller located between the third and fourth conveying rollers to support the curtain and pad fabric.

[0010] Furthermore, the first, third, fourth, and fifth conveyor rollers are arranged in a straight line, and the second conveyor roller is located on one side of the straight line containing the first and third conveyor rollers.

[0011] Furthermore, the curtain opening device also includes: a padding drive component, which is driven and connected to the padding winding mechanism, and drives the padding to move through the padding winding mechanism; and a material roll drive component, which is driven and connected to the material roll support mechanism, and drives the material to rotate through the material roll support mechanism. The driving force of the padding drive component on the padding is opposite to the driving force of the material roll drive component on the material, and the magnitude of the driving force of the padding drive component on the padding is greater than the driving force of the material roll drive component on the material.

[0012] Furthermore, the curtain opening device also includes a mat cloth correction detection component for correcting the deviation of the mat cloth. The mat cloth correction detection component is located between the mat cloth winding mechanism and the peeling roller mechanism. After the mat cloth is separated by the peeling roller mechanism, it is recycled to the mat cloth winding mechanism via the mat cloth correction detection component.

[0013] Furthermore, the mat winding mechanism includes a frame, a roller, and a correction drive. The roller is rotatably mounted on the frame, and the mat is wound and wound onto the roller. The roller is axially movable and driven by the correction drive, which drives the roller to move axially to change the direction of the mat's movement.

[0014] Furthermore, the curtain opening device also includes: at least one floating roller assembly, the floating roller assembly including a movably disposed floating roller, through which the separated curtain is conveyed; and at least one stretching roller, the stretching roller being located at the input end and / or output end of the floating roller assembly, through which the curtain is conveyed to or conveyed out of the floating roller assembly.

[0015] Furthermore, there are at least two floating roller assemblies, and the fabric guiding device also includes a pull-out roller assembly located between two adjacent floating roller assemblies, which drives the fabric on one floating roller assembly to be conveyed to the other floating roller assembly.

[0016] Furthermore, the fabric guiding device also includes: a movably mounted trolley frame, a material roll support mechanism, a padding roll mechanism, a peeling roller mechanism, and at least one floating roller assembly mounted on the trolley frame; a first correction mechanism, which is drivenly connected to the trolley frame and is capable of detecting the fabric offset between the floating roller assembly located on the trolley frame and the floating roller assembly not located on the trolley frame, so as to control the movement of the trolley frame for correction; and a second correction component, which is located at the conveying end of the floating roller assembly, through which the fabric is conveyed, and which can be deflected for deflection correction.

[0017] By applying the technical solution of this invention, the power provided by the padding cloth winding mechanism to the padding cloth is used as the main power for the overall material movement. This optimizes the force on the material from the traditional pulling of the curtain cloth to the pulling of the padding cloth. This reduces the force on the curtain cloth, preventing it from being stretched and deformed, and ensuring that the curtain cloth meets processing requirements. Simultaneously, to ensure that the force on the padding cloth achieves the effect of guiding the curtain cloth open, this embodiment also sets the peeling roller mechanism to include a first peeling component and a second peeling component, thus forming a two-stage separation. Specifically, when the material passes through the first peeling component, the curtain cloth and the padding cloth separate. During this process, the padding cloth still provides the main power for movement, i.e., the padding cloth drives the curtain cloth. After separation, the curtain cloth continues to move a short distance under the drive of the subsequent mechanism. During this process, the force on the curtain cloth is very small and will not affect the quality of the curtain cloth. The separated padding cloth and curtain cloth pass through the tail end of the first peeling component, that is, between the first and second peeling components. The two are then re-bonded. Unlike the previously rolled material, the adhesion between the curtain fabric and the padding fabric is not strong at this point. The padding fabric can only move the curtain fabric through friction. The adhesive force between them is very small, and they can be easily separated. Then, when they pass through the second peeling component, they are separated again. At this time, because the adhesion between the curtain fabric and the padding fabric is not strong, they can be easily separated. Thus, the curtain fabric does not require a large pulling force during subsequent conveying. It can simply be conveyed naturally after separation. The padding fabric after secondary separation is recycled to the padding fabric winding mechanism for recycling. This configuration ensures that the padding fabric is the main force when the curtain fabric is opened, while the curtain fabric itself experiences less force. This avoids the curtain fabric being stretched and deformed, which could affect subsequent processing. It ensures the quality of the curtain fabric cutting after being conveyed to the main machine, meets the customer's precision requirements for the fiber curtain belt layer, ensures that the product meets the customer's process requirements, reduces waste generation, lowers the customer's production costs, and improves the equipment's production efficiency.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0028] To address the problem that existing fiber curtain guiding devices cannot meet the fiber curtain guiding requirements in air springs, this invention provides a curtain guiding device.

[0029] like Figures 1 to 4The illustrated curtain opening device includes a roll support mechanism 10 for placing material formed by curtain and pad, a pad winding mechanism 20 for recycling the pad, and a stripping roller mechanism 30. One end of the pad is wound around the pad winding mechanism 20. The pad winding mechanism 20 drives the pad to move on the stripping roller mechanism 30, thereby driving the curtain to move on the stripping roller mechanism 30. The stripping roller mechanism 30 includes a first stripping component 31 and a second stripping component 32 arranged sequentially along the conveying direction. The material passes through the first stripping component 31 and the second stripping component 32 sequentially. When the material passes through the first stripping component 31, the curtain and the pad are separated. When the curtain and the pad are between the first stripping component 31 and the second stripping component 32, the curtain and the pad are attached. When the curtain and the pad pass through the second stripping component 32, the curtain and the pad are separated. The pad is recycled to the pad winding mechanism 20.

[0030] This embodiment uses the padding roll-up mechanism 20 to provide the main power for the overall material movement, thus optimizing the material's stress from the traditional tension on the curtain to the tension on the padding. This reduces the force on the curtain, preventing it from being stretched and deformed, and ensuring the curtain meets processing requirements. To ensure the padding's stress effectively guides the curtain apart, this embodiment also configures the peeling roller mechanism 30 to include a first peeling component 31 and a second peeling component 32, forming a two-stage separation. Specifically, when the material passes through the first peeling component 31, the curtain and padding separate. During this process, the padding still provides the main power for movement, i.e., the padding drives the curtain. After separation, the curtain continues to move a short distance under the drive of the subsequent mechanism. During this process, the curtain experiences very little force and does not affect its quality. The separated padding and curtain then pass the end of the first peeling component 31, i.e., between the first peeling component 31 and the second peeling component 32. Between points 2 and 3, the two are bonded together again. Unlike the previously rolled material, the adhesion between the curtain and the pad is not strong at this point; the pad can only move the curtain by friction. The adhesive force between them is very small, and they can be easily separated. Then, when they pass through the second peeling component 32, they are separated again. At this time, because the adhesion between the curtain and the pad is not strong, the curtain and the pad can be easily separated. Thus, the curtain does not require a large pulling force during subsequent conveying; it can simply be conveyed naturally. The pad after the second separation is recycled to the pad winding mechanism 20 for pad recycling. Through the above arrangement, the pad is the main force when the curtain is opened, and the curtain itself is subjected to less force. This avoids the curtain being stretched and deformed, which would affect subsequent processing. It ensures the quality of the curtain cutting after being conveyed to the main machine, meets the customer's precision requirements for the fiber curtain belt layer, ensures that the product meets the customer's process requirements, reduces waste generation, lowers the customer's production costs, and improves the production efficiency of the equipment.

[0031] like Figure 2 As shown, in this embodiment, the first peeling assembly 31 includes a first conveying roller 311, a second conveying roller 312, and a third conveying roller 313. The second conveying roller 312 is located between the first conveying roller 311 and the third conveying roller 313. The first conveying roller 311 and the third conveying roller 313 form a first conveying trajectory, and the first conveying roller 311, the second conveying roller 312, and the third conveying roller 313 form a second conveying trajectory. The first conveying trajectory and the second conveying trajectory are at least partially offset. In this embodiment, the first conveying trajectory is straight, more specifically, a horizontal trajectory, while the second conveying trajectory is U-shaped, approximately opening upwards. The first conveying trajectory is located at the opening of the second conveying trajectory, and the top two ends of the U-shaped trajectory are the first conveying roller 311 and the third conveying roller 313, which are also the positions where the curtain fabric and the pad fabric are separated and re-attached. In this way, when the composite material of the curtain fabric and the padding fabric passes through the first conveyor roller 311, the curtain fabric is conveyed horizontally along the first conveyor track, while the padding fabric is conveyed downwards along the second conveyor track, and the two separate, achieving a first separation between the curtain fabric and the padding fabric. Then, after the curtain fabric passes through the first conveyor track and the padding fabric passes through the second conveyor track, the curtain fabric and the padding fabric re-contact and adhere at the third conveyor roller 313, achieving a joint motion. Of course, the specific arrangement of the first conveyor roller 311, the second conveyor roller 312, and the third conveyor roller 313 can be changed as needed, as long as the first separation and re-adhesion between the curtain fabric and the padding fabric can be achieved.

[0032] In this embodiment, the second peeling assembly 32 includes a fourth conveying roller 321 located at the tail end of the peeling roller mechanism 30, and a third conveying roller 313 located between the fourth conveying roller 321 and the first conveying roller 311. Thus, the fabric and padding cloth bonded at the third conveying roller 313 are conveyed to the fourth conveying roller 321. Furthermore, the conveying directions of the fabric and padding cloth when they re-contact the bonded fabric at the third conveying roller 313 are different from those at the fourth conveying roller 321; that is, the subsequent conveying directions of the fabric and padding cloth are different, and their positions away from the fourth conveying roller 321 are different. Therefore, the fabric and padding cloth can undergo secondary separation at the fourth conveying roller 321, achieving fabric separation and guidance.

[0033] Optionally, the second stripping assembly 32 further includes at least one fifth conveying roller 322, located between the third conveying roller 313 and the fourth conveying roller 321. The fifth conveying roller 322 serves as a transition roller between the third conveying roller 313 and the fourth conveying roller 321. The specific number of fifth conveying rollers can be set according to the distance between the third conveying roller 313 and the fourth conveying roller 321, thereby supporting the curtain and pad fabric, preventing sagging in the middle, and ensuring smooth conveying. This embodiment uses one fifth conveying roller 322 as an example.

[0034] In summary, the peeling roller mechanism 30 of this embodiment includes five conveying rollers. The first conveying roller 311, the third conveying roller 313, the fourth conveying roller 321, and the fifth conveying roller 322 are arranged in a horizontal straight line. The second conveying roller 312 is located on one side of the straight line formed by the first conveying roller 311 and the third conveying roller 313, more specifically, it is located below the area between the first conveying roller 311 and the third conveying roller 313. Thus, the first conveying roller 311 and the third conveying roller 313 naturally form a straight first conveying trajectory, and the first conveying roller 311, the second conveying roller 312, and the third conveying roller 313 naturally form a U-shaped second conveying trajectory. Of course, the specific structural form of the peeling roller mechanism 30 is not limited to the arrangement described above in this embodiment. It can be adjusted as needed, as long as it can achieve the separation and bonding between the curtain fabric and the pad fabric.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the curtain opening device further includes a padding drive 40 and a material roll drive 50. The padding drive 40 is driven by the padding winding mechanism 20. The padding drive 40 drives the rollers of the padding winding mechanism 20 to rotate, thereby causing the rollers to retract the padding, providing the power for the padding's movement and thus driving the curtain's movement. Similarly, the material roll drive 50 is driven by the rollers of the material roll support mechanism 10. The material roll drive 50 drives the rollers to rotate, thereby causing the rollers to rotate the material, achieving the effect of rotating the material through the material roll support mechanism 10. However, it should be noted that the rotation of the roller driven by the material roll drive 50 is not for unloading the material, but rather to cooperate with the padding drive 40 to achieve material tension. Specifically, the driving force of the padding drive 40 on the padding is opposite to the driving force of the material roll drive 50 on the material, and the driving force of the padding drive 40 on the padding is greater than that of the material roll drive 50 on the material. In other words, the padding drive 40 drives the padding and the curtain to move in the conveying direction, while the material roll drive 50 operates in the opposite torque mode, driving the material to move in the opposite direction to the conveying direction. Furthermore, the driving force of the material roll drive 50 is relatively small, and its specific magnitude can be adjusted according to the size of the material roll and the padding roll. In this way, the cooperation between the material roll drive 50 and the padding drive 40 ensures that the padding and the curtain are always in a taut state, avoiding situations such as the padding being unable to drive the curtain to move or the material being unwound too much due to inertia. Meanwhile, the larger force of the padding ensures the normal opening of the curtain.

[0036] The specific types of the padding drive 40 and the material roll drive 50 can be selected as needed. In this embodiment, both are motors, and the output shaft of the motor is connected to the corresponding rollers to provide power.

[0037] In this embodiment, the curtain opening device further includes a mat cloth correction detection component 60 for correcting the mat cloth's deviation. The mat cloth correction detection component 60 is located between the mat cloth winding mechanism 20 and the peeling roller mechanism 30. The mat cloth, after being separated twice by the peeling roller mechanism 30, first passes through the mat cloth correction detection component 60 and then is rewound onto the mat cloth winding mechanism 20. This allows for the detection of the mat cloth's position. Correspondingly, the mat cloth winding mechanism 20 in this embodiment includes a frame, a roller, and a correction drive component. The roller is rotatably mounted on the frame, and the mat cloth is wound and rewound onto the roller. The roller is driven by the correction drive component. Furthermore, to achieve the aforementioned correction effect, the roller in this embodiment is axially movable, such as... Figure 3 As shown, when the padding cloth deviates from its designated position, the correction drive can drive the roller to move axially, thereby changing the direction of the padding cloth's movement. This ensures that the center of the padding cloth remains consistent when it is rolled up, preventing the curtain cloth from being pulled off-center due to the padding cloth deviating from its designated position.

[0038] In this embodiment, the curtain opening device further includes at least one floating roller assembly 70 and at least one stretching roller 80. The floating roller assembly 70 includes a movably disposed floating roller. The separated curtain fabric is conveyed via the floating roller. In this embodiment, the floating roller assembly 70 is vertically movable, and the floating roller is also vertically movable. Specifically, the downward force of the floating roller can be controlled by increasing or decreasing the counterweight, so that the tension deformation caused by the opening can be released when the curtain fabric passes through the floating roller, thereby adjusting the tension of the curtain fabric. The stretching roller 80 is located at the input end and / or output end of the floating roller assembly 70. The curtain fabric is conveyed to or conveyed out of the floating roller assembly 70 via the stretching roller 80. The stretching roller 80 can ensure that the curtain fabric is flat and does not wrinkle.

[0039] Optionally, there are at least two floating roller assemblies 70, and the curtain opening device further includes a pull-out roller assembly 90, which is located between two adjacent floating roller assemblies 70 and drives the curtain on one floating roller assembly 70 to be conveyed to the other floating roller assembly 70. This embodiment features two floating roller assemblies 70, arranged sequentially along the conveying direction. The fabric passes through both assemblies 70 in sequence. The floating roller assembly 70 closest to the conveying head, i.e., closest to the roll, has a stretching roller 80 on each side, while the other floating roller assembly 70 has no stretching rollers 80 on either side. A pull-out roller assembly 90 is positioned between the two floating roller assemblies 70. Thus, the separated fabric passes sequentially through one stretching roller 80, one floating roller assembly 70, another stretching roller 80, the pull-out roller assembly 90, and another floating roller assembly 70. This process releases tension twice, ensuring flatness. The pull-out roller assembly 90 provides power for conveying the fabric, ensuring it can be transferred from one floating roller assembly 70 to the other, while simultaneously trimming the fabric.

[0040] In this embodiment, the curtain opening device further includes a carriage frame 100, a first correction mechanism 110, and a second correction assembly 120. The carriage frame 100 is movably configured, and the material roll support mechanism 10, the padding fabric winding mechanism 20, the peeling roller mechanism 30, and at least one floating roller assembly 70 are disposed on the carriage frame 100. In this embodiment, the material roll support mechanism 10, the padding fabric winding mechanism 20, the peeling roller mechanism 30, and one floating roller assembly 70 are all disposed on the carriage frame 100. The first correction mechanism 110 is drivenly connected to the carriage frame 100 and can detect the curtain offset between the floating roller assembly 70 located on the carriage frame 100 and the floating roller assembly 70 not located on the carriage frame 100, that is, detect the curtain offset between the two floating roller assemblies 70, and thereby control the carriage frame 100 to swing and move according to the offset to perform correction. The second correction component 120 is located at the end of the conveying process of the floating roller assembly 70. That is to say, the fabric conveyed by the two floating roller assemblies 70 is then conveyed by the second correction component 120. The second correction component 120 can be a swingable correction roller and an electric cylinder. Under the detection of the wide-width photoelectric sensor, the second correction component 120 corrects the deviation of the fabric by having the electric cylinder push the correction roller to swing horizontally according to the deviation direction of the fabric, thereby ensuring that the fabric remains centered when conveyed to the subsequent equipment.

[0041] The first correction mechanism 110 performs coarse correction, and the second correction component 120 performs fine correction. The two work together to correct the deviation during the opening and conveying of the curtain. The deviation correction of the curtain works in conjunction with the aforementioned correction of the padding cloth and the floating roller assembly 70. The floating roller assembly 70 controls the release of the stretching deformation of the curtain. Through the padding cloth correction, coarse correction and fine correction of the curtain, the deviation is continuously corrected, thereby solving problems such as curtain deviation and pleating, and ensuring the quality of the curtain cutting after being conveyed to the main machine.

[0042] It should be noted that some components and mechanisms in this embodiment, such as the padding cloth correction detection component 60, the floating roller component 70, the pull-out roller component 90, the first correction mechanism 110, and the second correction component 120, can adopt existing technical solutions as needed. Therefore, this embodiment does not describe their specific structures in detail. Figure 2 and Figure 4 The dashed line represents the conveying path of the padding cloth, while the solid line represents the conveying path of the curtain cloth, or the curtain cloth and the padding cloth.

[0043] It should be noted that "multiple" in the above embodiments refers to at least two.

[0044] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0045] 1. This solves the problem that the existing fiber curtain opening device cannot meet the fiber curtain opening requirements in air springs;

[0046] 2. When the curtain is opened, the main force is the padding cloth, and the curtain itself is subjected to less force, which can avoid the curtain being stretched and deformed, thus affecting subsequent processing and other problems.

[0047] 3. The floating roller assembly controls the release of the tension deformation of the curtain fabric, and continuously corrects the deviation through padding, coarse deviation correction and fine deviation correction of the curtain fabric, thereby solving problems such as curtain fabric deviation and wrinkling.

[0048] 4. Ensure the quality of the fabric cutting after it is conveyed to the main unit, meet the customer's precision requirements for the fiber fabric belt layer, ensure that the products meet the customer's process requirements, reduce waste generation, reduce the customer's production costs, and improve the production efficiency of the equipment.
