Description

Technical Field

[0001] This invention relates to the field of curtain manufacturing technology, specifically to a composite machine for processing blackout curtains. Background Technology

[0002] The laminating machine for blackout curtains is the core equipment for achieving efficient lamination of decorative fabrics and linings to form finished blackout curtains. Its roller pressing precision, fabric protection capability, and lamination strength directly determine the appearance quality, blackout performance, and service life of the curtains, and are a key link restricting the large-scale production of high-end blackout curtains.

[0003] The current curtain processing industry faces severe technical challenges: on the one hand, the consumer market is constantly raising its requirements for the appearance, texture and durability of curtains, requiring laminating machines to avoid fabric scratches, wrinkles and delamination during high-speed production; on the other hand, under the trend of customized production, the combination of fabrics of different thicknesses and materials has put forward higher requirements for the adaptability of equipment, otherwise it will lead to an increase in the defect rate, affecting production efficiency and cost control.

[0004] Currently, in the field of blackout curtain processing and lamination, existing technologies still have the following shortcomings in practical application: Firstly, existing roller pressing assemblies struggle to balance fabric protection and pressure transmission capabilities: mainstream equipment often employs a traditional structure of "single active hard roller + driven soft roller." The soft roller acts only as a passive pressure-applying component, unable to actively adjust the pressure distribution, which can easily lead to scratches and roller marks on the upper decorative fabric (especially printed and jacquard fabrics) due to localized hard pressure, damaging the integrity of the appearance. At the same time, as the only active roller, the hard roller relies on fabric friction for pressure transmission, which can easily cause slippage of the lower lining and misalignment of the bonding surface, resulting in insufficient composite strength. The delamination rate after washing reaches 8%-12%, which not only increases rework costs but also seriously affects product durability. Furthermore, traditional roller groups are mostly arranged in parallel and facing each other, making it impossible to achieve step-by-step pressure application. One-time high pressure can easily cause glue overflow, contaminating the fabric surface and further reducing the finished product qualification rate.

[0005] Secondly, the existing transmission system lacks synchronization and linkage: the upper and lower roller groups of the existing equipment mostly adopt independent drive or single power transmission, which easily leads to speed difference, causing fabric stretching and wrinkling. This is especially prominent in wide-width (≥3 meters) production scenarios, where the asynchronous transmission between the edge and the center is more prominent. In addition, although some equipment is equipped with auxiliary roller groups, they are not linked with the main pressure roller, which easily leads to the auxiliary rollers "idling" or "lagging", failing to effectively smooth out fabric wrinkles and restricting the improvement of composite flatness.

[0006] Third, the existing secondary composite components lack gradient pressure and flexible adaptability: most of the existing secondary main pressure rollers are smooth cylindrical structures with constant roller pressure throughout the process, which cannot form a gradient effect of "light pressure first and then heavy pressure", which can easily lead to insufficient glue wetting or excessive pressure deformation of the fabric; at the same time, the roller surface material is uniform and cannot adapt to the protection needs of different fabrics, which poses a high risk of scratching to fragile fabrics such as silk and chiffon.

[0007] In view of this, the present invention proposes a composite machine for processing blackout curtains to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0008] To address the aforementioned technical problems, this invention provides a composite machine for processing blackout curtains, thereby resolving the technical issues raised in the background section.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a composite machine for processing blackout curtains, used to composite different curtain materials, including a composite machine body, with unwinding and rewinding workpieces respectively mounted on both sides of the composite machine body, a guide drive module installed inside the composite machine body, and a roller pressure adjustment component 1 inside the composite machine body, the roller pressure adjustment component 1 including a pressing roller and a supporting roller. After being conveyed by the unwinding workpiece, the different curtain materials are guided by the guide drive module to enter the interior of the composite machine body in a preliminary bonding form. The bonded curtain materials pass between the pressing roller 1 and the supporting roller 1, and are first subjected to upper roller pressure by the pressing roller, and then subjected to lower roller pressure by the supporting roller, realizing a bidirectional roller pressure bonding with alternating upper and lower sections.

[0010] Furthermore, the unwinding workpiece is a dual-station unwinding structure, used to simultaneously transport two different curtain materials. The upper layer of curtain material is decorative fabric, and the lower layer of curtain material is lining fabric. The two different curtain materials are kept aligned vertically during transport. The winding workpiece is arranged opposite to the unwinding workpiece and is used to collect the curtain material after pre-pressing and bonding inside the main body of the laminating machine and roll it into a roll for subsequent cutting and processing.

[0011] Furthermore, the guiding drive module includes a guide bracket for guiding the alignment of the two curtain materials. The guide bracket is rotatably connected to the inner wall of the laminating machine body. The laminating machine body is also symmetrically rotatably connected with a steering guide roller. The steering guide roller near the first pressing roller is used to assist the laminated curtain material in completing the turning and conveying, so that it smoothly enters the rolling area of ​​the first roller pressing adjustment component. The steering guide roller near the first supporting roller is used to assist the laminated and rolled curtain material in completing the turning and conveying, so that it smoothly conveys towards the winding workpiece. The laminating machine body is also equipped with a drive component.

[0012] Furthermore, the outer shell of the pressing roller is made of silicone or polyurethane (PU) material to protect the appearance of the upper curtain material. The supporting roller is made of rigid steel to provide stable support and transmit roller pressure, ensuring that the two curtain materials are firmly bonded together.

[0013] Furthermore, the roller pressing adjustment assembly also includes a pressing auxiliary roller and a supporting auxiliary roller. The pressing roller and the pressing auxiliary roller are arranged alternately along the conveying direction of the curtain material, and the supporting roller and the supporting auxiliary roller are also arranged alternately along the conveying direction of the curtain material.

[0014] Furthermore, an upper transmission component is assembled between the pressing roller 1 and the supporting auxiliary roller 1. The upper transmission component includes two upper rollers, which are respectively fixedly connected to the outer end walls of the pressing roller 1 and the supporting auxiliary roller 1, and are connected by an upper belt. A lower transmission component is assembled between the supporting roller 1 and the pressing auxiliary roller 1. The lower transmission component includes two lower rollers, which are respectively fixedly connected to the outer end walls of the supporting roller 1 and the pressing auxiliary roller 1, and are connected by a lower belt. Through synchronous transmission via the upper belt, the pressing roller 1 and the supporting auxiliary roller 1 rotate in the same direction and at the same speed. Through synchronous transmission via the lower belt, the supporting roller 1 and the pressing auxiliary roller 1 rotate in the same direction and at the same speed.

[0015] Furthermore, the main body of the laminating machine is equipped with a second roller pressure adjustment assembly, which includes a second pressing roller, a second supporting roller, a second pressing auxiliary roller, and a second supporting auxiliary roller. The second pressing roller and the second pressing auxiliary roller are arranged in parallel and vertically inclined, and the second supporting roller and the second supporting auxiliary roller are also arranged in parallel and vertically inclined. The two sets of rollers are arranged sequentially along the curtain material conveying direction to achieve continuous roller pressing and bonding.

[0016] Furthermore, the outer wall of the second pressing roller is uniformly fixedly connected with a number of trapezoidal protrusions, and the short side end face of the trapezoidal protrusion is fixedly connected with a soft shell made of silicone or polyurethane (PU) material, and the long side end face of the trapezoidal protrusion is fixedly connected to the roller body of the second pressing roller.

[0017] Furthermore, the second roller pressing adjustment assembly also includes a linkage shaft. A linkage transmission component is assembled between the second pressing roller and the linkage shaft. The linkage transmission component includes two linkage rollers. The two linkage rollers are respectively fixedly connected to the outer walls of the ends of the second pressing roller and the linkage shaft, and a linkage belt is connected between the linkage rollers.

[0018] Furthermore, an arc-shaped protrusion is fixedly connected to the outer wall of the linkage shaft, and the arc-shaped protrusion is located on the conveying path of the curtain material.

[0019] Compared with the prior art, the beneficial effects of the present invention are: (1) This device reconstructs the rolling logic of blackout curtain composite processing through the upper and lower staggered bidirectional rolling frame of the rolling adjustment component one. Compared with the traditional unidirectional rolling equipment, it can effectively avoid damage to the curtain raw material caused by one-time high pressure, and at the same time make the composite pressure act more evenly on the bonding surface of the decorative fabric and the lining, significantly improving the composite strength and the flatness of the finished product. The frame implements the upper rolling and lower support in steps, which not only protects the appearance integrity of the upper decorative fabric, but also ensures that the glue is fully impregnated through the stable pressure transmission of the support roller one. It solves the core contradiction of "difficulty in taking into account both surface protection and pressure transmission" in traditional equipment, making the equipment more versatile and stable when adapting to different fabric materials, and reducing the defect rate and rework cost in the production process.

[0020] In the actual rolling process, in the rolling adjustment component one, the pressing roller one adopts a soft outer shell made of silicone or polyurethane (PU) material, which forms a differentiated combination with the hard steel roller structure of the supporting roller one. This design of material and function specifically protects the upper decorative fabric that is easily scratched and deformed, while providing a reliable support and pressure transmission foundation for the lower lining. The staggered arrangement of the pressing roller one and the pressing auxiliary roller one, and the supporting roller one and the supporting auxiliary roller one along the conveying direction realizes the step-by-step linkage effect of "upper initial pressure + secondary pressing, lower initial pressure + secondary compaction". This not only effectively eliminates the air gaps and fine wrinkles left after the raw materials are bonded, but also allows the composite pressure to be evenly distributed along the full width of the raw materials, avoiding the problem of insufficient pressure at the edges or excessive pressure in the middle in traditional rolling, and further improving the consistency of composite quality.

[0021] The synchronous transmission design of the upper and lower transmission components, through the upper and lower belts respectively, enables the pressing roller 1 and the supporting auxiliary roller 1, and the supporting roller 1 and the pressing auxiliary roller 1 to rotate in the same direction and at the same speed. This ensures the coordination and precision of the movement between each roller group, avoiding problems such as fabric stretching, misalignment or wrinkling caused by speed differences. This transmission structure can realize multi-roller linkage without the need for an additional independent drive source, which simplifies the power system of the equipment and improves the reliability of operation and the convenience of maintenance. At the same time, in conjunction with the adaptive correction of the guide bracket and the smooth guidance of the steering guide roller in the guide drive module, the entire composite process from raw material alignment, rolling to finished product output forms a closed loop, further ensuring the efficiency and stability of blackout curtain composite processing.

[0022] (2) This device provides another independent and adaptable technical solution through the inclined continuous gradient roller pressing frame of the roller pressing adjustment component two. Compared with the traditional single-segment roller pressing structure, the two sets of rollers arranged in parallel and inclined directions are arranged in sequence along the conveying direction, so that the composite pressure can be applied to the curtain raw material in a continuous and gradual manner, avoiding the problems of fabric deformation and delamination caused by one-time high pressure in traditional equipment. At the same time, it allows the glue to be fully soaked and the composite to be more uniform. The frame is specifically adapted to the processing needs of fragile high-end decorative fabrics such as silk and chiffon. Through continuous main pressure composite, the flatness and durability of the finished product are greatly improved, meeting the quality requirements under harsh scenarios such as washing and long-term use, and providing reliable support for the large-scale production of high-end curtain products.

[0023] In the actual rolling process, the trapezoidal protrusions on the outer wall of the second pressing roller and the gradient pressure structure formed by the soft shell, as well as the arc-shaped protrusion design of the linkage roller shaft, optimize the fabric protection and composite effect during the rolling process in detail. The trapezoidal protrusions gradually increase the pressure thickness as the roller rotates, realizing a gradient change of "light pressure first, then heavy pressure". This avoids scratching and deformation of the upper decorative fabric due to instantaneous high pressure, and can gradually squeeze the glue layer, guiding a small amount of excess glue to flow to both sides of the roller to prevent contamination of the fabric surface. When the linkage roller rotates, the arc-shaped protrusions periodically and slightly press the raw material, effectively eliminating the tiny air bubbles remaining after bonding. At the same time, it helps the raw material to smoothly enter the next rolling process. Combined with the inclined pressing of the second pressing roller, it further flattens the fabric and improves the overall flatness.

[0024] The synchronous transmission design of the linkage drive components, and the inclined cooperation between the second support roller and the second support auxiliary roller, not only ensure the coordination and precision of the roller group's movement, but also form a differentiated technical solution from Embodiment 1, enhancing the equipment's adaptability to various scenarios. The linkage drive components achieve the same direction and speed rotation of the second pressure roller and the linkage shaft through the linkage belt, avoiding fabric stretching and misalignment problems caused by speed differences. At the same time, no additional drive source is required, simplifying the equipment structure. The stable pressure transmission of the second support roller and the secondary compaction of the second support auxiliary roller effectively improve the composite strength and prevent the raw material from rebounding and delaminating. Compared with the alternating bidirectional roller pressing of Embodiment 1, the inclined gradient roller pressing of this embodiment focuses more on the precise processing of high-end scenarios. It can be flexibly selected according to the fabric type and product positioning, allowing the equipment to perform optimally under different production needs. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. It should be noted that the laminating machine body 1, unwinding workpiece 11, rewinding workpiece 12, and guide drive module 2 in this device are all designed according to existing technology. The equipment's basic support, raw material conveying, finished product rewinding, and guide correction functions are achieved through conventional mechanical assembly methods. Among them, the frame dimensions, profile specifications, and welding process of the laminating machine body 1, the roller diameter, bearing model, and tension adjustment parameters of the unwinding workpiece 11, the roller speed, rewinding tension, and drive power of the rewinding workpiece 12, and the support structure, guide roller diameter, and installation angle of the guide drive module 2 are all existing technologies. The general connection, adaptation, and operating principles based on these structures are all mature technologies, and will not be repeated hereafter.

[0028] Example 1: Please refer to Figure 1 - Figure 4 as well as Figure 6 As shown, a laminating machine for processing blackout curtains is used to laminate different curtain materials 13. It includes a laminating machine body 1, with unwinding workpieces 11 and rewinding workpieces 12 mounted on both sides of the laminating machine body 1. A guide drive module 2 is installed inside the laminating machine body 1, and a roller pressure adjustment component 3 is set inside the laminating machine body 1. The roller pressure adjustment component 3 includes a pressing roller 31 and a supporting roller 33. After being conveyed by the unwinding workpiece 11, different curtain materials 13 are guided by the guide drive module 2 to enter the interior of the laminating machine body 1 in a preliminary bonding form. The bonded curtain materials 13 pass between the pressing roller 31 and the supporting roller 33. First, the pressing roller 31 performs upper roller pressure on the bonded curtain materials 13, and then the supporting roller 33 performs lower roller pressure on the curtain materials 13 after the preliminary roller pressure, realizing a bidirectional roller pressure bonding with alternating upper and lower rollers.

[0029] It should be noted that the unwinding workpiece 11 is a dual-station unwinding structure, used to simultaneously convey two different curtain materials 13. The upper layer conveys a decorative fabric, and the lower layer conveys a lining. The two different curtain materials 13 are kept aligned vertically during conveying. The winding workpiece 12 is positioned opposite to the unwinding workpiece 11 and is used to collect the curtain materials 13 after pre-pressing and bonding inside the laminating machine body 1 and wind them into a roll for subsequent cutting and processing. The guide drive module 2 includes a guide for aligning the two curtain materials 13. The guide bracket 21 is rotatably connected to the inner wall of the laminating machine body 1. The laminating machine body 1 is also symmetrically rotatably connected to the guide roller 22. The guide roller 22 near the pressing roller 31 is used to assist the curtain material 13 after lamination to complete the turning and conveying, so that it enters the rolling area of ​​the roller pressing adjustment component 3 smoothly. The guide roller 22 near the support roller 33 is used to assist the curtain material 13 after lamination and rolling to complete the turning and conveying, so that it is smoothly conveyed toward the winding workpiece 12. The laminating machine body 1 is also equipped with a drive component 23.

[0030] It should be noted that the upper decorative fabric is mostly cotton, linen, silk, or chemical fiber printed / jacquard fabric (easily scratched, easily deformed, and with requirements for appearance and texture), while the lower lining is mostly non-woven fabric, hot melt lining, or lightweight chemical fiber base fabric (wear-resistant, no appearance requirements, serves a shaping / supporting function).

[0031] Please refer to Figure 1 - Figure 7 As shown, the outer shell of the pressing roller 31 is made of silicone or polyurethane (PU) material to protect the appearance of the upper curtain material 13. The supporting roller 33 is made of hard steel roller to provide stable support and transmit roller pressure, ensuring that the two curtain materials 13 are firmly bonded. The roller pressure adjustment assembly 3 also includes a pressing auxiliary roller 32 and a supporting auxiliary roller 34. The pressing roller 31 and the pressing auxiliary roller 32 are arranged alternately along the conveying direction of the curtain material 13, and the supporting roller 33 and the supporting auxiliary roller 34 are arranged alternately along the conveying direction of the curtain material 13.

[0032] It should be noted that an upper transmission component 35 is assembled between the pressing roller 31 and the supporting auxiliary roller 34. The upper transmission component 35 includes two upper rollers, which are respectively fixedly connected to the outer end walls of the pressing roller 31 and the supporting auxiliary roller 34. An upper belt is connected between the upper rollers. A lower transmission component 36 is assembled between the supporting roller 33 and the pressing auxiliary roller 32. The lower transmission component 36 includes two lower rollers, which are respectively fixedly connected to the outer end walls of the supporting roller 33 and the pressing auxiliary roller 32. A lower belt is connected between the lower rollers. Through synchronous transmission via the upper belt, the pressing roller 31 and the supporting auxiliary roller 34 rotate in the same direction and at the same speed. Through synchronous transmission via the lower belt, the supporting roller 33 and the pressing auxiliary roller 32 rotate in the same direction and at the same speed.

[0033] Specifically, after the equipment starts, the unwinding workpiece 11, as a dual-station unwinding structure, has two sets of rollers rotating synchronously, conveying the two different curtain materials 13, namely the upper decorative fabric and the lower lining, at a uniform speed. During the conveying process, it is ensured that the upper and lower materials are always aligned. The two curtain materials 13 first enter the working area of ​​the guide drive module 2. The guide bracket 21, with its rotatable connection to the inner wall of the composite machine body 1, performs preliminary position calibration on the two materials, so that the lower lining is accurately attached to the lower surface of the upper decorative fabric, completing the initial attachment of the materials. At this time, the rotational adaptation characteristics of the guide bracket 21 can adaptively adjust according to the slight deviation of the material conveying, avoiding lateral misalignment of the two materials, laying the alignment foundation for subsequent roller pressing and laminating. The attached curtain material 13 continues to be conveyed, and the steering guide roller 22, which is close to the pressing roller 31, rotates accordingly. Its rotational support structure assists the attached material in changing the conveying direction, smoothly guiding the material to the roller pressing adjustment component 3 inside the composite machine body 1.

[0034] When the laminated curtain material 13 enters the working area of ​​the roller pressing adjustment component 3, it first contacts the pressing roller 31. At this time, the drive component 23, which starts synchronously with the equipment, continuously outputs power, driving the pressing roller 31 to rotate actively through the transmission structure. The outer shell of the pressing roller 31 is made of silicone or polyurethane (PU) material, so that it can adhere to the printed or jacquard texture of the upper decorative fabric during active rotation, and perform flexible upper roller pressing on the laminated curtain material 13. During this process, the rotation direction of the pressing roller 31... The roller pressing action, aligned with the direction of raw material conveying, not only initially eliminates the air gap between the two raw materials but also prevents scratches and roller marks on the upper decorative fabric caused by hard pressing, thus protecting the appearance of the upper raw material. At the same time, the upper belt in the upper transmission component 35 moves synchronously with the rotation of the pressing roller 31, driving the upper roller fixed to the end of the support auxiliary roller 34 to rotate synchronously, preparing for the power transmission of the subsequent linkage operation of the support auxiliary roller 34. The synchronous transmission characteristics of the upper transmission component 35 ensure the coordination of the roller group movement.

[0035] The curtain material 13, having completed the initial upper rolling, continues to move along the conveying direction and enters the working area of ​​the support roller 33. With the power from the drive component 23 synchronously transmitted to the support roller 33, the rigid steel roller is driven to rotate actively. As a rigid steel roller, the support roller 33 performs lower rolling on the curtain material 13 after the initial rolling during its active rotation, effectively transmitting the upper pressure applied by the pressing roller 31 to the bonding surface of the two materials. This ensures that the adhesive and materials are fully impregnated, improving the initial bonding strength. Due to the pressing roller 31 and the pressing auxiliary... Roller 32, support roller 33, and support auxiliary roller 34 are all arranged in an alternating pattern along the material conveying direction. After the material is rolled under the support roller 33, it immediately enters the working range of the pressing auxiliary roller 32. At this time, the lower belt in the lower transmission component 36 moves synchronously with the rotation of the support roller 33, driving the lower roller fixed at the end of the pressing auxiliary roller 32 to rotate in the same direction and at the same speed. The pressing auxiliary roller 32 then performs a second upper pressing on the material. Its function is to eliminate any fine wrinkles that may remain after the initial rolling of the pressing roller 31, and further smooth the fabric.

[0036] After the pressing auxiliary roller 32 completes the secondary pressing, the curtain material 13 continues to move towards the supporting auxiliary roller 34. At this time, the upper transmission component 35 has completed the power transmission, and the supporting auxiliary roller 34 rotates in the same direction and at the same speed as the pressing roller 31, applying a lower secondary supporting roller press to the curtain material 13 that has undergone secondary pressing. In this step, the rotation of the supporting auxiliary roller 34 and the supporting roller 33 work together to further compact the bonding surface of the two materials, completely eliminating the tiny air bubbles remaining between the layers. At the same time, its staggered arrangement with the pressing auxiliary roller 32 achieves "upper..." The step-by-step linkage effect of "top pressing + bottom compaction" ensures that the composite pressure is evenly distributed across the entire width of the raw material. After the roller pressing adjustment component 3 completes the bidirectional roller pressing process with alternating upper and lower sections, the curtain raw material 13 has completed pre-pressing and bonding. At this time, the guide roller 22, which is close to the support roller 33, rotates synchronously. Its guiding function assists the composite raw material in changing its conveying direction again, smoothly guiding the raw material to the winding workpiece 12. The setting of the guide roller 22 avoids delamination or deformation of the composite raw material when it exits the roller pressing area, ensuring the integrity of the pre-pressed composite product.

[0037] Example 2: Based on Example 1, please refer to... Figure 8 - Figure 11 As shown, the laminating machine body 1 is equipped with a roller pressure adjustment component 2 4. The roller pressure adjustment component 2 4 includes a pressing roller 2 41, a supporting roller 2 43, a pressing auxiliary roller 2 42, and a supporting auxiliary roller 2 44. The pressing roller 2 41 and the pressing auxiliary roller 2 42 are arranged in parallel and vertically inclined, and the supporting roller 2 43 and the supporting auxiliary roller 2 44 are arranged in parallel and vertically inclined. The two sets of rollers are arranged sequentially along the conveying direction of the curtain material 13 to achieve continuous roller pressure bonding.

[0038] It should be noted that a number of trapezoidal protrusions are uniformly fixedly connected to the outer wall of the second pressing roller 41. A soft shell made of silicone or polyurethane (PU) material is fixedly connected to the short side end face of the trapezoidal protrusion. The long side end face of the trapezoidal protrusion is fixedly connected to the roller body of the second pressing roller 41. The roller pressure adjustment component 4 also includes a linkage shaft 46. A linkage transmission component 45 is assembled between the second pressing roller 41 and the linkage shaft 46. The linkage transmission component 45 includes two linkage rollers. The two linkage rollers are respectively fixedly connected to the end outer walls of the second pressing roller 41 and the linkage shaft 46, and a linkage belt is connected between the linkage rollers. An arc-shaped protrusion is fixedly connected to the outer wall of the linkage shaft 46. The arc-shaped protrusion is located on the conveying path of the curtain material 13.

[0039] Specifically, based on the roller pressure adjustment component 24 in Embodiment 2, its conveying method is the same as in Embodiment 1. When the equipment is started, the unwound workpiece 11 can simultaneously convey two kinds of curtain raw materials 13: the upper decorative fabric and the lower lining fabric. After the guide bracket 21 of the guide drive module 2 completes precise alignment and preliminary bonding, it directly enters the working area of ​​the roller pressure adjustment component 24 inside the composite machine body 1. The bonded curtain raw material 13 moves along the conveying direction and sequentially approaches the pressing roller 21 and pressing auxiliary roller 22, which are arranged in parallel and inclined manner, as well as the supporting roller 23 and supporting auxiliary roller 244. The layout of the two sets of rollers arranged in sequence along the conveying direction provides a structural basis for continuous gradient main pressure composite, which is suitable for the stringent requirements of high-end fabrics for roller pressure accuracy.

[0040] When the curtain material 13 comes into contact with the pressing roller 41, the drive component 23, which starts synchronously with the equipment, continuously outputs power to drive the pressing roller 41 to rotate actively. The outer wall of the pressing roller 41 has several trapezoidal protrusions evenly distributed. The soft shell (silicone or polyurethane PU material) connected to its short side end face first contacts the upper decorative fabric. As the roller rotates, the thickness of the trapezoidal protrusions gradually increases, so that the pressure of the soft shell on the material changes from light to heavy, forming a gradient roller pressing effect of "light pressure first and then heavy pressure". This gradient pressure method not only avoids the high pressure from scratching or deforming the decorative fabric, but also gradually squeezes the glue layer, so that the glue can fully wet the bonding surface of the two materials. At the same time, the trapezoidal protrusion structure design can also guide a small amount of overflow glue to flow to both sides of the roller, preventing glue from contaminating the fabric surface. It is particularly suitable for the processing needs of fragile high-end decorative fabrics such as silk and chiffon.

[0041] When the second pressing roller 41 rotates, the linkage roller fixed at its end rotates synchronously. Through the linkage belt of the linkage transmission component 45, the power is transmitted to the linkage roller at the end of the linkage shaft 46, driving the linkage shaft 46 to rotate in the same direction. The rotation of the linkage shaft 46 drives the arc-shaped protrusion on its outer wall to move synchronously. The arc-shaped protrusion is located on the conveying path of the curtain material 13. During the rotation, it periodically and slightly presses the material to further eliminate the tiny air bubbles remaining after bonding. At the same time, it helps the material to smoothly enter the working area of ​​the second pressing roller 42. The second pressing roller 42 rotates synchronously with the power transmission of the linkage shaft 46, and performs upper secondary pressing on the material after gradient rolling. Its inclined parallel arrangement structure makes the pressing pressure evenly distributed along the width of the material, effectively smoothing out the local wrinkles that may appear after gradient rolling and improving the overall flatness of the fabric.

[0042] After the upper secondary pressing is completed, the curtain material 13 continues to be conveyed and enters the working range of the second support roller 43. As a rigid steel roller, the second support roller 43 actively rotates and provides stable lower support force, effectively transferring the pressure of the upper roller to the bonding surface of the two materials, ensuring that the glue and the lining are fully bonded, greatly improving the composite strength, and making it suitable for scenarios with high durability requirements such as washing and long-term use. Subsequently, the material enters the working area of ​​the second support auxiliary roller 44. The second support auxiliary roller 44 and the second support roller 43 are arranged in parallel and inclined, rotating synchronously to perform lower secondary compaction of the material, further eliminating the small gaps remaining between the layers. At the same time, its inclined structure allows the pressure to be released gradually along the material conveying direction, avoiding the material rebound and delamination caused by sudden pressure relief, and ensuring the stability of the composite structure.

[0043] After the gradient upper roller pressing, secondary pressing and lower support pressure transmission of the roller pressing adjustment component 2 4, the curtain raw material 13 completes independent secondary main pressing composite, and the composite strength and flatness are significantly improved, meeting the quality requirements of high-end blackout curtains. At this time, the composite raw material continues to be conveyed under the guidance of the support auxiliary roller 2 44. After being assisted in turning by the guide drive module 2, it smoothly enters the winding area of ​​the winding workpiece 12, and the winding workpiece 12 completes the winding and storage. This embodiment solves the problems of easy fabric damage and insufficient composite strength in traditional roller pressing methods through an independent inclined gradient roller pressing structure. It forms a differentiated solution from the upper and lower staggered bidirectional roller pressing of embodiment 1, and can be flexibly selected according to the needs of fabric type, product positioning and other scenarios.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
