Description

Technical Field

[0001] This application relates to the technical field of composite adhesive spraying machines, and in particular to a three-in-one adhesive spraying composite device. Background Technology

[0002] Currently, in industries such as textiles, apparel, home textiles, and automotive interiors, it is frequently necessary to laminate multiple layers of fabric to form composite materials with specific properties. Common lamination methods include hot melt lamination, solvent-based adhesive lamination, and spray lamination. Among these, spray lamination is widely used due to its advantages such as uniform adhesive layer, wide applicability to a wide range of fabrics, and high process flexibility.

[0003] Most existing adhesive laminating equipment can only laminate two layers of fabric. This involves two winding mechanisms and one adhesive spraying station, where one layer of fabric is sprayed with adhesive and then pressed together with another layer to form a double-layer composite fabric. When producing three or more layers of composite fabric, multiple laminating machines are typically used in series for multiple lamination processes, or two layers of fabric are first laminated into a semi-finished product, which is then transferred to another machine for a second lamination with the third layer. This segmented production method has the following problems: large equipment footprint, numerous intermediate steps, low production efficiency, frequent manual intervention, and the fabric is prone to stretching deformation or misalignment during multiple lamination processes, affecting the quality of the finished product. Furthermore, the adhesive layer of the semi-finished product may become contaminated or prematurely cured during handling, further reducing the lamination strength.

[0004] Therefore, how to provide a device that can continuously complete the spraying and bonding of three layers of fabric on one machine, so as to reduce the number of processes, improve efficiency and ensure the quality of the bonding, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] To address the problem of complex processes in existing multi-layer composite equipment, this application provides a three-in-one spray adhesive composite device.

[0006] This application provides a three-in-one adhesive spraying and laminating device, which adopts the following technical solution: A three-in-one adhesive spraying and laminating device includes a first winding mechanism, a second winding mechanism, and a third winding mechanism, which are spaced apart from each other. The first winding mechanism is used to wind and convey a first fabric, and the second winding mechanism is used to wind and convey a second fabric. A first laminating station is provided on the side of the second winding mechanism away from the first winding mechanism. A first adhesive spraying component is provided on the first laminating station. The first adhesive spraying component is used to spray adhesive onto the second fabric to laminate the second fabric with the first fabric to form a double-layer fabric. The third winding mechanism is used to wind and convey the third fabric. A second composite station is provided between the third winding mechanism and the first composite station. A second adhesive spraying component is provided on the second composite station. The second adhesive spraying component is used to spray adhesive onto the third fabric so that the third fabric is combined with the double-layer fabric to form a three-layer fabric. An automatic winding assembly is also provided between the third winding mechanism and the second composite station. The automatic winding assembly is used to wind up the three layers of fabric.

[0007] By adopting the above technical solution, and by setting the first composite station and the second composite station sequentially between the first winding mechanism, the second winding mechanism, and the third winding mechanism, and setting an automatic winding component downstream of the second composite station, the three-layer adhesive spraying and lamination of the first fabric, the second fabric, and the third fabric can be completed continuously on one machine without intermediate transfer or segmented production. This significantly reduces the equipment footprint and process steps, improves production efficiency, and avoids the problem of adhesive layer contamination or curing during the turnover of semi-finished products.

[0008] In some embodiments, the first winding mechanism, the second winding mechanism, and the third winding mechanism each include a winding roller, a correction component, and a tension detector. The winding roller is used to wind and convey the fabric. The correction component and the tension detector are both installed on the fabric output path of the winding roller. The correction component is used to correct the lateral position of the conveyed fabric, and the tension detector is used to monitor the tension on the fabric and output a tension signal.

[0009] In some embodiments, both the first and second glue spraying assemblies include a glue spray head, a glue supply line, and a glue pump. The glue pump is connected to the glue spray head through the glue supply line, and the glue spray head is positioned toward the fabric to spray glue.

[0010] In some embodiments, there are multiple spray nozzles, arranged at equal intervals along the width of the fabric, and each spray nozzle independently controls the amount of adhesive sprayed.

[0011] In some embodiments, the adhesive spraying assembly further includes a spreading roller disposed downstream of the spraying head, the spreading roller having an adjustable gap with the fabric surface for evenly spreading the sprayed adhesive on the fabric surface.

[0012] In some embodiments, the spray nozzle is a non-contact spiral spray nozzle with a spray angle of 30° to 90°, and a heating element is provided inside the spray nozzle to maintain the temperature of the adhesive within a set range.

[0013] In some embodiments, the automatic winding assembly includes a winding roller, a winding drive motor, a length sensor, and an automatic cutter. The winding drive motor is connected to the winding roller, the length sensor is disposed on the winding path to detect the winding length, and the automatic cutter is disposed between the winding roller and the second adhesive spraying assembly to automatically cut the three layers of fabric when a set length is reached.

[0014] In some embodiments, at least one set of pressing rollers is also included, which are disposed at the outlet of the first composite station and / or the second composite station, for pressing and bonding the glued fabric.

[0015] In some embodiments, a curing chamber is also included, which is disposed between the first adhesive spraying assembly and the first composite station, and / or between the second adhesive spraying assembly and the second composite station, for drying the fabric after adhesive spraying.

[0016] In some embodiments, a control system is also included, which is electrically connected to the tension detector, the correction assembly, the first glue spraying assembly, the second glue spraying assembly, and the automatic winding assembly, respectively, for adjusting the glue spraying amount and winding speed according to the tension signal.

[0017] Compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. By sequentially setting a first composite station and a second composite station between the first winding mechanism, the second winding mechanism, and the third winding mechanism, and setting an automatic winding component downstream of the second composite station, the three-layer adhesive spraying and lamination of the first fabric, the second fabric, and the third fabric can be completed continuously on one machine without intermediate transfer or segmented production. This significantly reduces the equipment footprint and process steps, improves production efficiency, and avoids the problem of adhesive layer contamination or curing of semi-finished products during turnover. 2. The first, second, and third winding mechanisms are all equipped with correction components and tension detectors, which can monitor and adjust the lateral position and conveying tension of each layer of fabric in real time, effectively preventing the fabric from running off-center or being stretched and deformed, ensuring the accurate alignment of the three layers of fabric at the composite station, thereby improving the appearance quality and mechanical properties consistency of the composite fabric. 3. The glue spray head adopts a structure with multiple nozzles arranged at equal intervals along the width of the fabric and the amount of glue sprayed can be controlled independently. Combined with a non-contact spiral spray nozzle and an adjustable glue roller, it can accurately spray according to the width of the fabric and the glue spraying needs of different areas, and spread the glue evenly on the fabric surface to avoid excessive or insufficient glue in some areas.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0024] Reference Figure 1This application provides a three-in-one adhesive spraying and laminating device, including a first winding mechanism 1, a second winding mechanism 2, and a third winding mechanism 3. The first winding mechanism 1, the second winding mechanism 2, and the third winding mechanism 3 are spaced apart along the fabric conveying direction. The first winding mechanism 1 is used to wind and convey a first fabric 14, and the second winding mechanism 2 is used to wind and convey a second fabric 21. A first laminating station 4 is provided on the side of the second winding mechanism 2 away from the first winding mechanism 1. A first adhesive spraying component 6 is provided on the first laminating station 4, and the first adhesive spraying component 6 is used to spray adhesive onto the second fabric 21, so that the second fabric 21 and the first fabric 14 are laminated to form a double-layer fabric. The third winding mechanism 3 is used to wind and convey a third fabric 31. A second laminating station 5 is provided between the third winding mechanism 3 and the first laminating station 4. A second adhesive spraying component 7 is provided on the second laminating station 5, and the second adhesive spraying component 7 is used to spray adhesive onto the third fabric 31, so that the third fabric 31 and the aforementioned double-layer fabric are laminated to form a three-layer fabric. An automatic winding assembly 8 is also provided between the third winding mechanism 3 and the second composite station 5. The automatic winding assembly 8 is used to wind up the final three-layer fabric.

[0025] With the arrangement of the three winding mechanisms, two laminating stations, and corresponding adhesive spraying components, the adhesive spraying and laminating of three layers of fabric can be completed continuously on one machine without intermediate transfer, significantly improving production efficiency. Meanwhile, the automatic winding component 8 enables automatic collection of finished products, further enhancing the automation level of the equipment.

[0026] like Figure 2 As shown, this embodiment optimizes the specific structure of each winding mechanism. It is easy to understand that in this embodiment, the first winding mechanism 1, the second winding mechanism 2, and the third winding mechanism 3 have the same structure. Taking the first winding mechanism 1 as an example, the first winding mechanism 1 includes a winding roller 11, a correction assembly 12, and a tension detector 13. The winding roller 11 is used to wind and transport the fabric. The correction assembly 12 and the tension detector 13 are both installed on the fabric output path of the winding roller 11. The correction assembly 12 is used to correct the lateral position of the fabric during transport, preventing fabric deviation and resulting in misalignment during lamination. The tension detector 13 is used to monitor the tension on the fabric and output a tension signal so that the subsequent control system can adjust the unwinding speed or tension adjustment device to ensure that the fabric maintains appropriate tension during the lamination process, avoiding stretching deformation or loosening and wrinkling.

[0027] Furthermore, this embodiment describes the specific structure of the adhesive spraying assembly. For example... Figure 3As shown, both the first glue spraying assembly 6 and the second glue spraying assembly 7 include a glue spray head 61, a glue supply line 62, and a glue pump (not shown in the figure). The glue pump is connected to the glue spray head 61 through the glue supply line 62. The glue pump pumps glue from the glue storage container (not shown in the figure) and delivers it to the glue spray head 61 through the glue supply line 62. The glue spray head 61 is oriented towards the fabric to spray glue. The pumped glue supply method ensures the continuity and stability of the glue supply. The amount of glue sprayed can be controlled by adjusting the speed of the glue pump or the opening time of the glue spray head 61.

[0028] To further improve the uniformity and flexibility of adhesive spraying, such as Figure 3 As shown, there are multiple spray nozzles 61, arranged at equal intervals along the width of the fabric, and each spray nozzle 61 independently controls the amount of adhesive sprayed. For example, multiple solenoid valves can be used to control the on / off state and adhesive flow rate of each spray nozzle 61, thereby enabling precise spraying according to the actual needs of different width areas of the fabric. For example, the amount of adhesive sprayed can be increased in the edge area of ​​the fabric to prevent delamination, or selective spraying can be performed according to the composite pattern.

[0029] like Figure 1 As shown, the first glue spraying assembly 6 and the second glue spraying assembly 7 also include a glue-spreading roller 64 disposed downstream of the glue spraying head 61. The glue-spreading roller 64 has an adjustable gap with the fabric surface, which can be changed, for example, by manually adjusting the lead screw or automatically adjusting the cylinder. When the glued fabric passes through the glue-spreading roller 64, the roller 64 can, on the one hand, evenly spread the sprayed glue between the two layers of fabric, making the glue layer thickness uniform and avoiding excessive or insufficient glue in some areas; on the other hand, it can compress the two layers of fabric, making them adhere tightly together, thereby improving the consistency of composite strength and appearance quality.

[0030] This embodiment optimizes the specific type of the spray nozzle. The spray nozzle 61 adopts a non-contact spiral spray nozzle with a spray angle of 30° to 90° (e.g., 45°, 60°, or 90°) to adapt to different fabric widths and spraying distances. Non-contact spraying avoids contamination or damage to the fabric caused by contact between the nozzle and the fabric. At the same time, the spray nozzle 61 is equipped with a heating element (e.g., a heating wire or a PTC heater) to maintain the adhesive temperature within a set range (e.g., 80°C to 150°C), preventing the adhesive from becoming too viscous due to temperature drop, which could lead to poor spraying or atomization. This is especially suitable for hot melt adhesives or moisture-curing adhesives that require constant temperature spraying.

[0031] Furthermore, this embodiment provides a detailed description of the specific structure of the automatic winding assembly 8. The automatic winding assembly 8 includes a winding roller, a winding drive motor, a length sensor, and an automatic cutter. The winding drive motor (e.g., a servo motor) is connected to the winding roller and drives it to rotate to wind up three layers of fabric. The length sensor (e.g., a rotary encoder or laser rangefinder) is positioned on the winding path to detect the winding length. When the detected winding length reaches a preset threshold, the control system sends a signal. The automatic cutter (e.g., a pneumatic cutter or an electric hot cutter) is positioned between the winding roller and the second adhesive spraying assembly 7 to automatically cut the three layers of fabric when the set length is reached, thereby achieving fixed-length winding and automatic roll changing without manual intervention, thus improving production efficiency.

[0032] like Figure 1 As shown, the apparatus of this embodiment further includes at least one set of pressing rollers 9. The pressing rollers 9 are disposed at the outlets of the first composite station 4 and / or the second composite station 5. Specifically, a pair of mutually pressing rollers 9 are disposed at the outlet of the first composite station 4 to press and bond the first fabric 14 and the second fabric 21 after adhesive spraying; similarly, pressing rollers 9 are disposed at the outlet of the second composite station 5 to press and bond the third fabric 31 after adhesive spraying with the double-layer fabric. The pressing rollers 9 can be made of rubber or metal, and their surfaces can have patterns to increase bonding strength or form specific textures. The pressing pressure can be adjusted by a spring or a cylinder.

[0033] To accelerate adhesive curing and reduce waiting time, the apparatus in this embodiment also includes a curing chamber (not shown in the figure). The curing chamber is located between the first adhesive spraying assembly 6 and the first lamination station 4, and / or between the second adhesive spraying assembly 7 and the second lamination station 5. The curing chamber can be a hot air drying chamber, an infrared radiation chamber, or an ultraviolet curing chamber (selected according to the type of adhesive), used to dry the fabric after adhesive spraying, so that the adhesive is partially or completely cured, thereby improving the initial adhesion after lamination and preventing displacement during subsequent conveying or pressing processes.

[0034] To achieve fully automatic closed-loop control, the device in this embodiment also includes a control system (e.g., a PLC controller or an industrial computer). The control system is electrically connected to the tension detector 13, the web guiding assembly 12, the first glue spraying assembly 6, the second glue spraying assembly 7, and the automatic winding assembly 8. The control system receives the tension signal output by the tension detector 13. When the tension deviates from the set range, it automatically adjusts the unwinding speed of the first winding mechanism 1, the second winding mechanism 2, or the third winding mechanism 3, or the torque of the magnetic powder brake. Simultaneously, it dynamically adjusts the glue spraying amount of the first glue spraying assembly 6 and the second glue spraying assembly 7 according to the tension change (e.g., by adjusting the speed of the glue pump or the duty cycle of the glue spraying head 61), and correspondingly adjusts the speed of the winding drive motor in the automatic winding assembly 8 to ensure constant winding tension. Through this control system, intelligent and precise control of the glue spraying and laminating process can be achieved, reducing the scrap rate.

[0035] The following is combined Figures 1 to 3 Briefly describe the working process of the three-in-one spray adhesive compounding device of this application.

[0036] First, the first fabric 14 is released from the upper roller 11 of the first upper winding mechanism 1, and enters the first composite station 4 after passing through the correction component 12 and the tension detector 13. At the same time, the second fabric 21 is released from the second upper winding mechanism 2, and also reaches the first composite station 4 after passing through the correction and tension detection. At the first composite station 4, the glue spraying head 61 of the first glue spraying component 6 sprays glue onto the surface of the second fabric 21 (the glue is delivered by the glue pump and glue supply pipeline 62, and is kept at a constant temperature by the heating element). After being glued, the second fabric 21 passes through the glue spreading roller 64 to spread the glue evenly, and then enters the pressing roller together with the first fabric 14, and is composited into a double-layer fabric under pressure.

[0037] Subsequently, the double-layer fabric continues to be conveyed to the second composite station 5. At the same time, the third winding mechanism 3 releases the third fabric 31, which, after correction and tension detection, arrives at the second composite station 5. At the second composite station 5, the second adhesive spraying assembly 7 sprays adhesive onto the surface of the third fabric 31, and after uniform adhesive application and pressing, the third fabric 31 is composited with the double-layer fabric to form a three-layer fabric.

[0038] Finally, the three layers of fabric enter the automatic winding assembly 8, where they are wound up by the winding rollers. A length sensor monitors the winding length in real time, and when the set length is reached, an automatic cutting blade cuts the fabric, completing one winding unit. Throughout the process, the control system adjusts the operating parameters of each mechanism in real time based on the signal from the tension detector 13 to ensure composite quality.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
