Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fiber cloth conveying, and in particular to a fiber cloth anti-wrinkle conveying device. BACKGROUND

[0002] In the production and processing process of fiber cloth, the anti-wrinkle treatment of the conveying link is a key process to ensure product quality. Due to the material characteristics of fiber cloth, it is prone to wrinkles under the influence of factors such as stress and temperature change. Once wrinkles are formed, it will not only affect the precision of subsequent cutting, sewing and other processes, but also reduce the appearance quality and market competitiveness of the final product. Therefore, efficient and reliable anti-wrinkle conveying technology has always been an important research direction in the industry.

[0003] At present, the traditional fiber cloth conveying device has many limitations in anti-wrinkle treatment. Most devices use single-sided heating to iron and shape the cloth. High-temperature gas only acts on the single surface of the cloth, resulting in uneven heating of the cloth, large temperature difference between the surface and the inner layer, and inconsistent softening of the fibers. It is difficult to fundamentally eliminate deep wrinkles, and local wrinkles may still remain after conveying. At the same time, the conveying device lacks dynamic adjustment capability in pressure control. The pressure distribution of the roller on the cloth is fixed, and it cannot be adjusted according to the characteristics of different areas of the cloth. This leads to the possibility of cloth damage due to excessive pressure in some areas, and ineffective ironing due to insufficient pressure in other areas, further exacerbating the generation of wrinkles.

DETAILED DESCRIPTION

[0030] A first pressure roller 15 and a second pressure roller 16 are rotatably connected between two mounting plates 1 along the fabric conveying direction. The second pressure roller 16 is located below the first pressure roller 15 and is positioned close to the transport roller 9. An electrostatic device 10 is fixedly installed between the two mounting plates 1, located above the transport roller 9 and corresponding to its position. The electrostatic device 10 is equipped with multiple electrostatic elimination nozzles 11 for spraying ion air. A mounting rod 17 and a transparent elastic membrane 21 are also fixedly installed between the mounting plates 1. The mounting rod 17 is located above the transparent elastic membrane 21, and both are positioned between the transport roller 9 and the output roller 20. Multiple detection wheels 18 are rotatably connected to the outer wall of the mounting rod 17. The multiple detection wheels 18 are linearly distributed and correspond to the position of the transparent elastic membrane 21. A sensor 19 is fixedly installed on each detection wheel 18. An air jet assembly is provided between the transport roller 9 and the transparent elastic membrane 21. The air jet assembly includes a first air jet roller 26 and a second air jet roller 32. The second jet roller 32 is located between the first jet roller 26 and the transport roller 9. A fixing rod 29 is provided below both the first jet roller 26 and the second jet roller 32. The two ends of the fixing rod 29 are rotatably connected to the corresponding mounting plate 1. The two ends of the first jet roller 26 are fixedly connected to the corresponding fixing rod 29 below it via a first moving arm 25. The two ends of the second jet roller 32 are fixedly connected to the corresponding fixing rod 29 below it via a second moving arm 27. Pushing assemblies are provided at both ends of the first jet roller 26. Each pushing assembly includes a second electric push rod 23 fixedly installed on the outer wall of the mounting plate 1. The telescopic end of the second electric push rod 23 is fixedly connected to the fixing rod 29 below the first jet roller 26 via a connecting arm 24. Telescopic assemblies are provided at both ends of the second jet roller 32. Each telescopic assembly includes a third electric push rod 28 fixedly installed on the inner wall of the mounting plate 1. The telescopic end of the third electric push rod 28 is rotatably connected to the corresponding second moving arm 27.

[0031] The fabric is first guided and flattened above the first pressure roller 15, then wrapped around to the bottom of the second pressure roller 16 for further compaction. It then passes under the electrostatic device 10 for static elimination treatment, and then wraps back above the transport roller 9 to maintain stable tension. Afterward, it passes sequentially through the second air-jet roller 32 and the first air-jet roller 26 for airflow leveling and correction, and finally passes between the detection wheel 18 and the transparent elastic membrane 21. After quality inspection, it is conveyed to the output roller 20. The arrangement of the first pressure roller 15 and the second pressure roller 16 applies uniform vertical pressure to the fabric, ensuring stable fabric position during cutting, effectively eliminating wrinkles and preventing deviation. Simultaneously, the second pressure roller 16 is located diagonally below the first pressure roller 15, forming an inclined pressure gradient. When the fabric passes through the gap between the two rollers, they apply pressures with different directions. The first pressure roller 15 provides vertical support, while the second pressure roller 16 applies downward diagonal pressure. The resulting lateral shearing force effectively flattens fabric wrinkles and eliminates internal stress. During the conveying process, the electrostatic device 10 sprays ion wind through the electrostatic elimination nozzle 11. The positive and negative ions released by the ion wind can quickly neutralize the positive / negative static electricity on the fabric surface. Compared with the single grounding or humidification method, its electrostatic elimination efficiency is higher and the effect is more thorough. It can also eliminate wrinkles caused by static electricity at the same time. Secondly, after the static electricity is eliminated, the charge on the fabric surface is zero, and it loses its ability to adsorb particles in the air, thereby effectively preventing dust from adhering. In addition, the airflow blown evenly by the electrostatic elimination nozzle 11 can make the fabric adhere tightly to the conveyor roller 9, which can not only blow away the dust attached to the surface, but also further eliminate fabric wrinkles.

[0032] The fabric passes under the second air-jet roller 32 and above the first air-jet roller 26 in an S-shaped path, making direct contact with both rollers. Simultaneously, the high-temperature gas acts on both sides of the fabric. Compared to single-sided belt contact or short-path conveying, this significantly extends the fabric's residence time in the high-temperature environment and avoids uneven heating on one side. This allows the fabric fibers to soften fully from the surface to the inner layer, effectively eliminating any wrinkles on the fabric surface and improving fabric smoothness. The second electric push rod 23 continuously extends and retracts, pushing the connecting arm 24 to move the first air-jet roller 26. The third electric push rod 28 extends and retracts continuously, driving the second air-jet roller 32 to move. The two air-jet rollers continuously make arc-shaped movements, so that the contact point between the air-jet rollers and the fabric changes continuously with the movement. The high-temperature gas is no longer limited to acting on the fabric in a fixed area, but can cover more corners of the fabric surface, allowing wrinkles that might otherwise be missed to also come into contact with high-temperature softening and ironing treatment, further improving the comprehensiveness of softening and wrinkle prevention. At the same time, the pressure is dynamically distributed on the fabric surface, ensuring that each area receives appropriate ironing pressure, avoiding problems such as local overpressure damage or underpressure ineffectiveness.

[0033] A supplementary light 22 is installed below the transparent elastic membrane 21. Multiple detection rollers 18 press down sequentially. Sensors 19 are used to detect the light transmittance of the fabric in both elastic and stretched states. The sequential pressing of multiple detection rollers 18 creates dynamic compressive stress, performing a final physical wrinkle removal before the fabric enters the output stage. This process gradually eliminates any remaining local wrinkles on the fabric surface and provides secondary reinforcement for wrinkles that may spring back after air jet treatment. Sensors 19 assess the flatness of the fabric by detecting its light transmittance in both elastic and stretched states. Wrinkled areas experience reduced light transmittance due to fiber stacking, while smooth areas have uniform light transmittance. The cooperation between the transparent elastic membrane 21 and the detection rollers 18 ensures that the fabric maintains a stable stretched state during testing, guaranteeing accurate detection. The supplementary light 22 enhances light penetration, avoiding detection errors caused by insufficient light. This not only filters out unqualified wrinkled fabrics but also optimizes front-end processing parameters, such as roller pressure, air jet intensity, and tension, through the detection data, forming a closed loop of processing, detection, and feedback to continuously improve wrinkle resistance stability.

[0034] A cutting assembly is provided on the side of the first pressure roller 15 away from the transport roller 9. The cutting assembly includes a knife holder 4, on which a cutting knife 5 is provided. A first electric push rod 6 is fixedly installed on the side of the two mounting plates 1 that are close to each other, and the telescopic end of the first electric push rod 6 is fixedly connected to the knife holder 4. When the fabric needs to be divided during transportation, the first electric push rod 6 can be activated to push the knife holder 4 and drive the cutting knife 5 to approach the first pressure roller 15 to perform fabric cutting.

[0035] In use, the invention first starts the drive motor 31, which drives the drive shaft 8 and the transport roller 9 to rotate via the transmission belt. The first electric push rod 6 is activated to push the knife holder 4 to move the cutting knife 5 away from the first pressure roller 15. The fabric is first passed through the first pressure roller 15 from above, so that it contacts the surface of the first pressure roller 15. Then the fabric is passed through the second pressure roller 16 from below. At this time, the first pressure roller 15 is below the fabric and the second pressure roller 16 is above the fabric. The fabric then passes through the area below the electrostatic device 10 and contacts the upper surface of the transport roller 9. The fabric is then moved to the area below the second air jet roller 32 and then turned to the area above the first air jet roller 26, undergoing air jet treatment in sequence. Finally, the fabric passes through the area below the detection wheel 18 and makes close contact with the detection wheel 18 and the transparent elastic film 21. After passing the inspection, the fabric is output through the output roller 20. When the fabric needs to be cut during transportation, the first electric push rod 6 can be activated to push the knife holder 4 forward, so that the cutting knife 5 is close to the first pressure roller 15; then the cutting knife 5 is activated, and the fabric cutting operation is completed when the blade head extends. During the conveying process, the electrostatic device 10 continuously sprays ion wind from the electrostatic elimination nozzle 11 to neutralize the positive / negative static electricity on the fabric surface. At the same time, the second electric push rod 23 and the third electric push rod 28 are activated to drive the first moving arm 25 and the second moving arm 27 to operate, so that the two first air-jet rollers 26 and the second air-jet roller 32 perform reciprocating arc motion within a specific angle range, with the second air-jet roller 32 located above the fabric and the first air-jet roller 26 located below the fabric.

[0036] The fabric is pressed onto the transparent elastic membrane 21 by the detection wheel 18. After the supplementary light 22 is turned on, the detection wheel 18 presses down sequentially. In conjunction with the sensor 19, the light transmittance of the fabric in both elastic and stretched states can be detected simultaneously. At the same time, the sequential pressing action of the detection wheel 18 can also eliminate any wrinkles that may exist on the surface of the fabric. During the conveying process, the reduction motor 30 drives and controls both sides of the transport roller 9 through the transmission roller 13 and the transmission gear 14 to ensure that the axial load of the roller is evenly distributed.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
