Description

Technical Field

[0001] This utility model relates to the technical field of substrate production equipment, and in particular to a substrate film-laying system and a composite flooring production line. Background Technology

[0002] In the production process of composite flooring, a lamination process is usually required during the flooring's movement to improve its surface properties or meet specific functional requirements. However, due to initial positioning errors during installation, including axial position deviations and angular misalignments, existing technologies lack effective adjustment mechanisms. This can lead to a mismatch between the film release direction and the composite flooring's movement direction, resulting in lamination offset and reduced lamination quality. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a substrate film-laying system and a composite flooring production line, which solves the technical problem that the lack of an effective adjustment mechanism in the prior art leads to a mismatch between the film release direction and the composite flooring travel direction, which in turn easily causes film offset and reduces the film quality.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] In a first aspect, this utility model provides a substrate film-laying system for passively releasing a film roll onto a substrate. The system includes an adjusting support device adapted to support the film roll and to align the axial orientation of the film roll with the transport posture of the substrate. The adjusting support device includes a first frame, a rotating shaft, and a support assembly. Both ends of the rotating shaft are axially rotatably supported on the support assembly, and the support assembly is movably supported on the first frame. The support assembly is capable of axially limited sliding and oscillating along a first vertical axis, thereby driving the rotating shaft and the film roll wound on the rotating shaft to slide axially with limited positioning and oscillate along the first vertical axis with limited positioning, thus aligning the axial orientation of the film roll with the transport posture of the substrate.

[0008] In one technical solution of this utility model, the support assembly includes a rotating seat and a first connecting seat located at one end of the rotating shaft, and an axial slide, a swing slide, and a second connecting seat located at the other end of the rotating shaft.

[0009] In one technical solution of this utility model, a correction device is also included, which is suitable for correcting the axial position of the film roll. The device includes a second frame and a telescopic drive member. The first frame is axially slidably connected to the second frame. The two ends of the telescopic drive member are respectively fixedly connected to the first frame and the second frame, so that the first frame has the freedom to slide axially relative to the second frame.

[0010] In one technical solution of this utility model, the web-correcting device further includes a web-correcting sensor and a web-correcting controller. The web-correcting sensor is adapted to detect the lateral edge position of the film before the film is laminated onto the substrate. The web-correcting sensor and the telescopic drive are both connected to the web-correcting controller so that the lateral edge position of the film roll can be driven by the telescopic drive to drive the first frame and thus drive the film roll to slide axially to match the edge position of the substrate.

[0011] In one technical solution of this utility model, a tension adjustment device is also included, which is suitable for adjusting the tension of the film after the film roll is passively released. The device includes a damper, which is provided on at least one of the first connecting seat and the second connecting seat and provides adjustable damping for the rotation of the rotating shaft.

[0012] In one technical solution of this utility model, the tension adjustment device further includes a tension controller and a tension sensor. The tension sensor is suitable for detecting the tension of the film roll when it is passively released. The tension controller is connected to the tension sensor and the damper.

[0013] In one technical solution of this utility model, multiple substrate film placement systems are configured, and the types of film rolls released by different substrate film placement systems may be the same or different.

[0014] In one technical solution of this utility model, the substrate film placement system is located below the substrate; the second frame can also be axially slid to a maintenance position away from the position below the substrate.

[0015] In one technical solution of this utility model, a base frame is also included, which is supported below the base plate, and the second frame is axially slidably connected to the base frame.

[0016] Secondly, this utility model provides a composite flooring production line, including the substrate film placement system in the above technical solution, and also includes two sets of parallel pressure rollers, which form a pressing channel between the substrate and the film; the two pressure rollers can approach each other to press the film onto the substrate.

[0017] (III) Beneficial Effects

[0018] The beneficial effects of this utility model are as follows: The substrate film-laying system and composite flooring production line of this utility model, because the film roll has the freedom of axial sliding and swinging along the first axis, thus forming a dual-level adjustment mechanism, which includes both axial translation adjustment and circumferential swing adjustment, so that the film roll can match the spatial position of the substrate and be adjusted to the optimal film-laying posture before film-laying, which significantly improves the consistency of film-laying quality, reduces the scrap rate, and improves the production quality of composite boards.

[0034] To better explain and facilitate understanding of this utility model, the following description is provided in conjunction with the appendix. Figures 1-7 This invention will be described in detail through specific embodiments. Wherein, directional terms such as "upper" and "lower" are used in this document. Figure 1 The orientation is used as a reference, and "axial direction" refers to the direction of the axis of the rotating shaft 11.

[0035] Example 1:

[0036] Reference Figures 1-7 This utility model provides a substrate film-laying system for passively releasing the film 200 of a film roll 300 onto a substrate 100. The system includes an adjusting support device 1 adapted to support the film roll 300 and align its axial orientation with the transport posture of the substrate 100. The adjusting support device 1 includes a first frame 15, a rotating shaft 11, and a support assembly. Both ends of the rotating shaft 11 are axially rotatably supported on the support assembly, which is movably supported on the first frame 15. The support assembly is capable of axially limited sliding and oscillating along a first vertical axis, thereby enabling the rotating shaft 11 and the film roll 300 wound on the rotating shaft 11 to slide axially with limited positioning and oscillate along the first vertical axis with limited positioning, thus aligning the axial orientation of the film roll 300 with the transport posture of the substrate 100.

[0037] The support assembly includes a rotating seat 12 and a first connecting seat 17 located at one end of the rotating shaft 11, and an axial slide 13, a swing slide 14 and a second connecting seat 16 located at the other end of the rotating shaft 11.

[0038] Rotary seat 12 is rotatably connected to first frame 15 along first vertical axis. First connecting seat 17 is axially movable and connected to rotary seat 12. Fixed part of swing slide 14 is supported on first frame 15 and its swing axis is first vertical axis. Fixed part of axial slide 13 is fixedly connected to moving part of swing slide 14. First connecting seat 17 is fixedly connected to moving part of axial slide 13.

[0039] The two ends of the rotating shaft 11 are rotatably connected to the first connecting seat 17 and the second connecting seat 16 respectively. The axial slide 13 can drive the rotating shaft 11 and the first connecting seat 17 to move synchronously in a limited position through the second connecting seat 16. The swing slide 14 can drive the axial slide 13 to swing in a limited position along the first vertical axis.

[0040] In this embodiment, the rotating shaft 11 is used to mount the film roll 300 and serves as its rotational output component. Both ends of the rotating shaft 11 are supported and positioned by a first connecting seat 17 and a second connecting seat 16, respectively. The first connecting seat 17 and the rotating seat 12 form a sliding fit, allowing the first connecting seat 17 to slide within a limited range along the axis of the rotating shaft 11. The rotating seat 12 itself is pivotally connected to the first frame 15 about the first vertical axis, forming a hinged fulcrum that can deflect around the vertical direction. The second connecting seat 16 is rigidly fixed to the moving end of the axial slide 13 and can move synchronously with the slide. The fixed end of the axial slide 13 is integrated into the moving part of the swing slide 14, and the entire assembly is supported by the swing slide 14 and can be adjusted by a limited angle along the first vertical axis.

[0041] Since the swing axis of the swing slide 14 and the rotation axis 11 of the rotating seat 12 are the same first vertical axis, the entire support structure forms a coaxial swing system around the same central axis, ensuring geometric consistency and force symmetry during the movement process.

[0042] The axial slide 13 can drive the first connecting seat 17 and the second connecting seat 16 to move axially synchronously, adjust the relative position of the film roll 300 in the axial direction, compensate for the initial installation error, and ensure that the film release area is always precisely aligned with the lateral position of the substrate 100.

[0043] At the same time, the swing slide 14 can also drive the entire axial slide 13 assembly and the second connecting seat 16 connected thereto to swing around the first vertical axis, adapting to the trajectory change or deflection of the substrate 100 in the forward direction, and avoiding misalignment.

[0044] In this embodiment, the adjustment support device 1 enables the film roll 300 to have the freedom of axial sliding and swinging along the first axis, thereby forming a two-level adjustment mechanism that includes both axial translational adjustment and circumferential swing adjustment. This allows the film roll 300 to match the spatial position of the substrate 100 and be adjusted to the optimal posture for coating 200 before coating 200, which significantly improves the consistency of coating 200 quality, reduces the scrap rate, and improves the production quality of the substrate 100.

[0045] Specifically, both the axial slide 13 and the swing slide 14 can be set as manually adjustable slides, for example, by using a handwheel to rotate the lead screw, the lead screw drives the slider, and the slider drives the corresponding component to move. The relative sliding can be locked by tightening the lead screw with bolts.

[0046] Furthermore, the axial slide 13 and the swing slide 14 can be stacked with the axial slide 13 on top or the swing slide 14 on top, which can be flexibly selected by relevant personnel.

[0047] For the swing slide 14, since it is swinging, the slider can still slide along a straight line on the fixed part of the swing slide 14. The slider drives the moving part of the swing slide 14 to swing relative to the fixed part of the swing slide 14 along the first vertical axis by abutting against the moving part of the swing slide 14.

[0048] Additionally, a tightening bolt can be installed on the rotating seat 12. The bolt can be threaded onto the rotating seat 12, and the end of the bolt can press against the first frame 15 after the bolt is tightened, thereby limiting the rotation angle of the rotating seat 12. The rotating seat 12 and the first frame 15 are connected by a bearing assembly to ensure the rotational connection accuracy and smooth rotation.

[0049] The substrate film-laying system can be used to produce PET flooring, thereby improving the production efficiency and quality of PET flooring.

[0050] Example 2:

[0051] Reference Figures 1-7 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0052] The substrate film placement system also includes a correction device 2, which is adapted to correct the axial position of the film roll 300. It includes a second frame 21 and a telescopic drive 22. The first frame 15 is axially slidably connected to the second frame 21. The two ends of the telescopic drive 22 are respectively fixedly connected to the first frame 15 and the second frame 21, so that the first frame 15 has the freedom to slide axially relative to the second frame 21.

[0053] In this embodiment, a correction device 2 is further introduced, which includes a second frame 21 and a telescopic drive component 22, significantly enhancing the system's dynamic adjustment capability and process adaptability. The first frame 15, as a load-bearing structure, not only supports components such as the rotating seat 12, the swing slide 14, the axial slide 13, the first connecting seat 17, and the second connecting seat 16, but is also movably mounted on the second frame 21 via an axial sliding connection, thereby enabling the entire film-laying mechanism to perform axial displacement in the traveling direction of the substrate 100. This technical solution overcomes the limitations of traditional fixed film-laying frames, allowing the overall position of the film roll 300 to be dynamically adjusted according to the actual requirements of the film 200.

[0054] The telescopic drive component 22 serves as an active adjustment unit, with its two ends connected between the first frame 15 and the second frame 21, forming a push-pull linkage structure. By controlling the telescopic stroke of the telescopic drive component 22, such as by using a cylinder, hydraulic cylinder, or electric push rod, the first frame 15 can be precisely driven to slide axially on the second frame 21, thereby driving the entire membrane roll 300 support system to move synchronously.

[0055] The telescopic drive 22, in conjunction with the axial slide 13, enables the film roll 300 to have dual axial adjustment capabilities. The axial slide 13 is a manual slide, which can be used to correct the axial position of the film roll 300 during the initial debugging stage. The telescopic drive 22, on the other hand, is not manually telescopic but intelligently controlled, allowing it to dynamically adjust the axial position of the film roll 300 during its release, making it more accurately fit the actual position of the substrate 100.

[0056] This axial sliding degree of freedom, together with the local adjustment capabilities provided by the original axial slide 13 and swing slide 14, forms a multi-level collaborative compensation mechanism to ensure that the release axial position of the thin film 200 always maintains the best matching relationship with the motion trajectory of the substrate 100.

[0057] Example 3:

[0058] Reference Figures 1-7 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0059] The substrate film placement system correction device 2 also includes a correction sensor 23 and a correction controller. The correction sensor 23 is adapted to detect the lateral edge position of the film 200 before the film 200 is laminated onto the substrate 100. The correction sensor 23 and the telescopic drive 22 are both connected to the correction controller so that the lateral edge position of the film roll 300 can be driven by the telescopic drive 22 to drive the first frame 15 to slide axially and adapt to the edge position of the substrate 100.

[0060] In this embodiment, a web-alignment sensor 23 and a web-alignment controller are introduced into the aforementioned substrate lamination system, further realizing intelligent and closed-loop control of the lamination process, significantly improving the accuracy and automation level of film bonding. The web-alignment sensor 23 is arranged at an appropriate position on the travel path of the film 200, enabling real-time and continuous detection of the actual positional changes of the edge of the film 200, capturing its minute offsets or fluctuations in the width direction. This detection does not rely on manual observation or preset parameters, but is based on principles such as optics, ultrasound, or image recognition to achieve dynamic sensing of the edge position of the film 200, ensuring the sensitivity and accuracy of the feedback signal.

[0061] The output signal of the correction sensor 23 directly interacts with the telescopic drive component 22 to form a control linkage, constituting a complete "detection-feedback-execution" closed-loop adjustment system. When the sensor detects a lateral shift at the edge of the film 200, it immediately transmits the deviation signal to the correction controller and generates a control command accordingly, driving the telescopic drive component 22 to perform telescopic movements in the corresponding direction and stroke. Since one end of the telescopic drive component 22 is connected to the first frame 15 and the other end is fixed to the second frame 21, its movement directly pushes or pulls the first frame 15 to slide axially along the second frame 21, thereby causing the entire film roll 300 support structure to move synchronously. This overall displacement adjusts the release position of the film roll 300, ensuring that the edge of the film 200 is always in a predetermined position, thus maintaining alignment with the edge of the substrate 100.

[0062] Through the coordinated action of the correction sensor 23, the correction controller and the telescopic drive component 22, the system has the ability to predict and respond to changes in external working conditions, avoiding quality problems such as uneven edges of the film 200, insufficient coverage or excessive overlap, and greatly improving production efficiency and product consistency.

[0063] Specifically, the correction sensor 23 can employ a vision-based approach, utilizing a vision camera to detect the lateral edge position of the thin film 200 in real time. Alternatively, it can employ a sensing approach, using a C-shaped sensor to construct a space that allows the thin film 200 to pass through, essentially a photoelectric sensor. When the thin film 200 passes through this space, the C-shaped sensor can detect the edge position of the thin film 200. This is an existing technology and will not be detailed here.

[0064] Example 4:

[0065] Reference Figures 1-7 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0066] The substrate film placement system also includes a tension adjustment device 3, which is suitable for adjusting the tension of the film 200 after the film roll 300 is passively released. The device includes a damper 31, which is at least provided on the second connecting seat 16 or the first connecting seat 17 and provides adjustable damping for the rotation of the rotating shaft 11, thereby adjusting the tension of the film 200 after the film roll 300 is passively released.

[0067] In this embodiment, the damper 31 is mounted on at least one connecting seat and forms an indirect or direct linkage with the rotating shaft 11. By applying an adjustable resistance torque to the rotational motion of the rotating shaft 11, it actively intervenes in the tension of the film 200 during the passive release of the film roll 300. The damping effect is not a rigid locking mechanism, but a controllable energy dissipation mechanism. It can provide a continuous and stable reverse torque when the film roll 300 rotates and releases the film due to the traction of the substrate 100, thereby controlling the tension of the film 200 after the film roll 300 is released. By adjusting the damping force of the damper 31, for example, by using an adjustable pneumatic damper, hydraulic damper, or magnetic powder braking structure, a suitable damping value can be preset according to process parameters such as film type, thickness, width, and the traveling speed of the substrate 100. This ensures that the film release process at different stages can maintain a uniform tension level, avoid the occurrence of "loose film" or "stacked" phenomena, and ensure that the film 200 is always in a moderately taut state, thereby improving the flatness and bonding quality of the coating.

[0068] The damping function of the tension adjustment device 3 complements and synergizes with other adjustment mechanisms in the system: the correction sensor 23 and the telescopic drive 22 are responsible for the lateral alignment of the membrane roll 300 in space, while the damper 31 focuses on the mechanical control of the rotational degree of freedom, stabilizing the output tension of the membrane from the source. Together, they form a comprehensive control system integrating position adjustment, posture adaptation, and tension management. This multi-dimensional synergistic control is particularly crucial when dealing with thin, easily stretchable, or high surface energy membrane materials, and can significantly reduce common defects such as wrinkling, stretching deformation, and edge warping.

[0069] Adjustability gives the equipment stronger process adaptability, allowing operators to quickly adjust damping parameters based on actual operating results, adapting to various membrane materials and production rhythms without replacing hardware. This design not only improves the stability and consistency of the lamination process but also extends the service life of the membrane roll 300, reduces the risk of membrane breakage, and provides key technical support for achieving high-quality, high-efficiency, and minimally-interventional continuous composite production.

[0070] Example 5:

[0071] Reference Figures 1-7 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0072] The substrate film release system tension adjustment device 3 also includes a tension controller 32 and a tension sensor. The tension sensor is suitable for detecting the tension of the film roll 300 when it is passively released. The tension controller 32 is connected to the tension sensor and the damper 31.

[0073] In this embodiment, the tension adjustment device 3 further integrates a tension sensor and a tension controller 32, realizing closed-loop, dynamic, and intelligent control of the tension of the film 200, significantly improving the system's adaptability and process accuracy under complex working conditions. The tension sensor, in conjunction with the guide roller, is positioned in the film 200 transport path, for example, near the exit of the film roll 300 or the pressing point of the film 200. It can detect the actual tension value of the film 200 in real time and accurately during the passive release process, and continuously feed it back to the tension controller 32, forming a continuous monitoring loop to ensure that the system always monitors the tension state of the film surface.

[0074] The tension controller 32 receives real-time data from the tension sensor and compares it with a preset target tension range. Once the actual tension deviates from the set value, the controller immediately generates a corresponding adjustment command and outputs a control signal to the damper 31. The damper 31 dynamically adjusts the resistance torque applied to the rotating shaft 11 according to the received command: when the tension is too low, the damping force is appropriately increased to prevent the film 200 from loosening, wrinkling, or drifting; when the tension is too high, the damping force is reduced to prevent the film material from being overstretched or even breaking. This process is continuous, smooth, and responsive, effectively suppressing the impact of transient disturbances on the coating quality.

[0075] The introduction of the closed-loop control mechanism of the tension adjustment device 3 transforms the damping setting, which originally relied on manual experience for adjustment, into automatic and precise intelligent control. Especially during high-speed operation or long-term continuous production, the moment of inertia and film unwinding characteristics of the film roll 300 change continuously throughout its entire service life, from full roll to hollow core. Traditional fixed damping is insufficient to maintain constant tension. However, through the coordinated action of the tension controller 32 and the sensor, the system can achieve "constant tension" film unwinding. Regardless of the size of the film roll 300, it can maintain a stable and consistent output tension, thereby ensuring the uniformity of film 200 lamination and the appearance quality.

[0076] Furthermore, the tension adjustment device 3 and the aforementioned correction mechanism form a complementary function. The correction system is responsible for aligning the membrane roll 300 in the lateral position, ensuring edge matching; while the tension control system focuses on optimizing the longitudinal mechanical behavior, ensuring a smooth and wrinkle-free membrane surface. Together, they enable high-precision control of the coating process in both spatial position and mechanical state. Simultaneously, since the entire adjustment process requires no human intervention, operational errors are reduced, and the automation level and process repeatability of the equipment are improved.

[0077] Example 6:

[0078] Reference Figures 1-7 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0079] Multiple substrate film placement systems are configured, and the film rolls released by different substrate film placement systems may be of the same or different types.

[0080] In this embodiment, the substrate film-laying system is configured as multiple units, forming a highly flexible and redundant multi-station coating architecture, which significantly expands the equipment's process adaptability and production continuity. Multiple film-laying systems are arranged side-by-side along the travel path of the substrate 100, operating independently but collaboratively serving the same production line. Each film-laying system can possess complete functions such as a rotating shaft 11, a first connecting seat 17, a second connecting seat 16, an axial slide 13, a swing slide 14, damping adjustment, tension control, and correction response, enabling it to independently complete the installation, release, and dynamic bonding process of the film roll 300.

[0081] The membrane rolls 300 carried by the membrane deployment system can be configured to be of the same or different types according to process requirements. When different types of membrane rolls 300 are configured, the system has the ability to composite multilayer membrane materials, realizing multifunctional and multi-structure integrated composite, and meeting the diverse requirements of high-end products for composite layers and performance combinations.

[0082] The setup of multiple film-laying systems incorporates a "in use" and "standby" operation mode switching mechanism. During normal production, one or more systems are in operation, handling the film coating operations required for the current process; while the remaining systems are pre-installed with the film rolls 300 needed for the next process, and have completed preparations such as tension preset, damping adjustment, and position alignment, remaining in standby mode. When the current film roll 300 is about to run out or a film type needs to be changed, the control system automatically switches to the standby system, achieving seamless handover. During this process, the original operating system is taken out of service for roll changing or maintenance, while the new system immediately begins operation, avoiding production interruptions caused by downtime for film changes and greatly improving equipment operating efficiency and continuous operation capability.

[0083] Furthermore, this multi-system architecture enhances the production line's fault tolerance. If a film feeding system malfunctions or breaks, the control system can quickly shut it down and activate a backup unit to continue production, preventing the entire line from shutting down and ensuring production stability and delivery cycle reliability. Combined with an automatic film splicing device or transition roller 5, fully automated film changing and splicing can even be achieved, further reducing manual intervention.

[0084] In summary, by setting up multiple substrate coating systems, not only are the process requirements for multiple film types and multi-layer composites achieved, but a dynamic switching and redundancy backup operation mechanism is also established, making the entire coating process more efficient, flexible, and reliable. This design is particularly suitable for flexible production lines producing a variety of products in small batches or with high added value, providing a highly integrated and intelligent solution for modern composite material manufacturing.

[0085] Example 7:

[0086] Reference Figures 1-7 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0087] The substrate film placement system is located below the substrate 100; the second frame 21 can also slide axially to a maintenance position away from the substrate 100.

[0088] In this embodiment, the substrate film placement system is arranged entirely below the substrate 100, making full use of the space below the production line and achieving a compact layout.

[0089] The bottom-mounted design not only optimizes the overall structure of the production line, but also enables the film 200 to be smoothly bonded to the bottom surface of the substrate 100 from bottom to top by means of the tension of the film itself and the guidance of the guide roller, reducing wrinkles or loosening caused by gravity sagging. It is especially suitable for the lamination process of low rigidity and high extensibility film 200.

[0090] Based on this, the second rack 21 is designed to slide axially and move out to a maintenance position away from the base plate 100 directly below, further improving the maintainability and operational safety of the system.

[0091] During normal operation, the second frame 21 is located in the working area below the substrate 100, ensuring that the film 200 released by the film roll 300 can adhere to the bottom surface of the substrate 100 with the shortest path and the smallest deviation angle, thus ensuring the coating accuracy and stability.

[0092] When it is necessary to replace the film roll 300 or handle film breakage, the entire second frame 21, along with its rotating seat 12, axial slide 13, swing slide 14, first connecting seat 17, second connecting seat 16, and rotating shaft 11, can be moved axially to a preset maintenance position. This position is located outside the travel path of the substrate 100, away from the operating substrate and transmission components, creating ample operating space. This movable maintenance design eliminates the need for operators to perform high-altitude, crouching, or traversing operations in narrow or dangerous areas, significantly reducing maintenance difficulty and safety risks. Furthermore, in multi-system configurations, other film-laying systems can continue operating while the second frame 21 is being moved, achieving an efficient "online operation, offline maintenance" mode and minimizing downtime. In addition, the removal process is smooth and controllable, avoiding accidental collisions with precision sensors, dampers 31, or tension control elements, protecting the calibration accuracy and lifespan of critical components.

[0093] The overall sliding capability of the second rack 21 is integrated with the aforementioned functions such as automatic correction, tension control, and multi-system switching. During daily operation, high-precision film coating is achieved through closed-loop adjustment using sensors; while during maintenance, rapid connection and disconnection are achieved through physical displacement, forming an organic unity of "intelligent operation" and "convenient maintenance." This design fully considers the dual requirements of equipment availability and operational efficiency for continuous industrial production. It not only improves the human-machine interface experience but also enhances the practicality and sustainable operation capability of the entire film coating system under actual working conditions, providing crucial support for building an efficient, safe, and intelligent substrate 100 production line.

[0095] Reference Figures 1-7 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0096] The substrate film placement system also includes a base frame 4, which is supported below the substrate 100, and a second frame 21 is axially slidably connected to the base frame 4.

[0097] In this embodiment, the base frame 4 serves as a fundamental support platform, directly supported by the equipment frame or ground foundation beneath the substrate 100. Its position corresponds to the travel path of the substrate 100, providing a solid and rigid mounting reference for the entire film-laying mechanism. The second frame 21 is axially slidably connected to the base frame 4 via guide rails, sliders, or linear bearings, enabling it to move smoothly along the travel direction of the substrate 100 and freely switch between working and maintenance positions.

[0098] The base frame 4 not only bears the static weight and dynamic load of the second frame 21 and all its components, including the rotating shaft 11, the first connecting seat 17, the second connecting seat 16, the axial slide 13, the swing slide 14, the damper 31, and the sensors, but also effectively resists vibrations and impacts caused by the traction of the substrate 100, changes in membrane tension, or the movement of the telescopic drive component 22 during system operation, avoiding coating deviations caused by structural swaying. Its rigid support characteristics ensure the straightness of the trajectory and positioning accuracy of the second frame 21 during sliding, preventing movement deviations caused by frame deformation or loose connections, thereby ensuring the accuracy and repeatability of the membrane roll 300 position adjustment.

[0099] Furthermore, the presence of the base frame 4 provides a unified installation reference when multiple substrate placement systems are arranged side-by-side, facilitating coordinated layout and synchronous control among multiple systems. Different placement units can slide independently on the same base frame 4 or parallel base frames 4 without interfering with each other, supporting simultaneous operation and allowing individual units to be removed for maintenance without affecting the overall production line operation. This modular and standardized installation method improves the scalability of the equipment and the flexible configuration capability of the production line.

[0100] Specifically, casters can be installed at the bottom of the base frame 4, and a brake function is provided. When it is necessary to remove the second frame 21, the brake can be activated, and the handle on the second frame 21 can be manually pulled to remove it as a whole.

[0101] In summary, the base frame 4 is not only a component of the supporting structure, but also the fundamental guarantee for the stable sliding, precise positioning and safe maintenance of the second frame 21. It improves the rigidity, precision and maintainability of the whole machine, and enables the film spreading system to maintain long-term stable performance in high-speed, continuous and high-load industrial environments. It provides a solid and reliable mechanical platform for achieving high-quality film coating and efficient production and operation.

[0102] Example 9:

[0103] Figures 1-7 In addition to providing a composite flooring production line, the present invention includes the substrate film feeding system in any of the above embodiments. When producing PET flooring, the film roll 300 can be an IXPE roll or a PVC roll. The composite flooring production line also includes two sets of parallel pressure rollers 5, which form a pressing channel between the substrate 100 and the film 200. The two pressure rollers 5 can approach each other to press the film 200 onto the substrate 100.

[0104] IXPE material, short for Electron Radiation Crosslinked Polyethylene Foam, is made primarily of polyethylene, mixed with several other additives free of harmful substances, and extruded into a high-tech, high-grade closed-cell foam material. Through green and healthy irradiation processing technology, the crosslinking effect of electron ion radiation alters the original structure of the base material, forming a network of independent closed-cell cells.

[0105] Film 200 protects the sheet material, enhancing its durability and aesthetics. IXPE boasts excellent overall performance, offering heat reflection, insulation, sound insulation, radiation reflection, shock absorption, and noise reduction. It also provides moisture resistance, sun protection, waterproofing, seepage prevention, good sealing, aging resistance, and energy-saving insulation. In summer, it offers moisture protection, sun protection, and heat insulation, saving on air conditioning costs; in winter, it provides insulation, saving on heating costs, resulting in significant energy savings.

[0106] In this embodiment, the composite flooring production line integrates the aforementioned substrate film-laying system, constructing a highly automated and high-precision film-laminating and pressing process. During the operation of the entire line, the substrate moves continuously along a set path, and the substrate film-laying system configured below it releases the film roll according to process requirements. For example, when producing PET flooring, the film roll can be an IXPE roll or a PVC roll as the functional layer film material.

[0107] During this process, the multiple adjustment functions of the film release system work together. The correction sensor 23 monitors the position of the substrate edge in real time, and the linkage telescopic drive 22 drives the first frame 15 to slide axially to ensure that the release edge of the film roll is always aligned with the substrate. The tension sensor and tension controller 32 form a closed-loop system, which dynamically adjusts the resistance torque applied to the rotating shaft 11 by the damper 31, so that the film material maintains constant tension throughout the entire roll diameter change cycle, avoiding stretching deformation or loosening and wrinkling.

[0108] The pressure rollers 5 are located on the upper and lower sides of the substrate 100, respectively. The upper pressure roller 5 is located above the substrate, while the lower pressure roller 5 is located below the substrate, with the side covered by the film 200 facing the lower pressure roller 5, forming a contact relationship of "substrate—film 200—pressure roller 5". Driven by pneumatic, hydraulic, or electric actuators, the two sets of pressure rollers 5 can approach or separate from each other, applying uniform pressure in close contact during operation to firmly press the film 200 onto the substrate surface. The pressure can be precisely adjusted according to the film thickness, material characteristics, and bonding requirements to ensure a tight interface, free of bubbles and wrinkles, without damaging the substrate structure or the functional layer of the film. The entire production line organically combines the film feeding system with the double-sided pressure roller 5 pressing mechanism, completing the entire process from film release, position adjustment, dynamic correction, tension control to final bonding.
