Description

Technical Field

[0001] This utility model relates to the technical field of multi-layer thermal insulation material processing equipment, specifically to a rewinding and spot welding device for multi-layer thermal insulation materials and a thermal insulation material production system. Background Technology

[0002] Multilayer thermal insulation materials, as key functional materials in aerospace, building energy conservation, and new energy vehicles, are typically manufactured through a composite process using multiple layers such as metal foil, polymer film, and insulation cotton. To ensure interlayer bonding strength and prevent interlayer slippage caused by vibration or thermal stress during operation, spot welding is required to firmly fix each layer, maintaining the overall structural stability and thermal insulation performance. Currently, the industry generally adopts two processing modes: one is a step-by-step processing method of "rewinding and collecting materials first, then offline spot welding," where the material is moved to an independent spot welding device for offline processing after rewinding; the other is to integrate the spot welding mechanism onto the rewinding machine, but spot welding can only be performed when rewinding is paused (i.e., stop-work spot welding). However, both methods have systemic technical bottlenecks that severely restrict production efficiency and product quality.

[0003] Specifically, the step-by-step processing mode requires additional secondary material loading and positioning, significantly increasing the time spent on process connections; the stop-and-weld mode leads to frequent interruptions in the rewinding process, extending the processing time per roll by 30%-50%, failing to meet the timeliness requirements of mass production. Simultaneously, offline spot welding requires recalibrating the material position, with spot weld deviations generally exceeding ±0.5mm, compromising the structural consistency of the insulation material; and during the restart of rewinding after a stop, the material is prone to tensile deformation due to sudden tension changes, further exacerbating the loss of control over spot welding accuracy. Furthermore, both modes rely on manual intervention: step-by-step processing requires dedicated personnel for process transitions and positioning calibration, while the stop-and-weld stage requires manual adjustment of the welding head position, resulting in high labor costs. More importantly, existing spot welding mechanisms are mostly designed for materials of fixed thickness. When the number of layers or thickness parameters of multi-layer insulation materials change (such as customized requirements for different application scenarios), it is necessary to stop the machine to replace the welding head or reset the parameters, lacking dynamic adaptability and significantly reducing production line flexibility. In summary, existing technologies have multiple shortcomings in terms of efficiency, accuracy, automation, and adaptability, making it difficult to achieve efficient, precise, and low-labor continuous production.

[0020] In related technologies, the step-by-step processing mode of the production process of multi-layer thermal insulation materials requires additional secondary material loading and positioning, which significantly increases the time spent on process connection and leads to high labor costs due to reliance on manual intervention.

[0022] It is understandable that this application, by installing a non-stop spot welding module on the rewinding equipment, enables high-precision spot welding of multi-layer thermal insulation materials during continuous rewinding without stopping the rewinding process. It also features adaptive parameter adjustment and automatic spot positioning functions, meeting the needs of efficient and high-quality continuous production.

[0023] In some alternative embodiments, the frame assembly 1 is provided with a plurality of guide roller groups 8, each of the guide roller groups 8 being inserted into the reflective layer roll portion 3 or the spacer layer roll portion 4.

[0024] Understandably, the guide roller assembly precisely guides the transmission path of multi-layer materials, effectively suppressing interlayer slippage and material tensile deformation, reducing spot weld deviation, significantly improving structural consistency, and ensuring the stability of thermal insulation performance.

[0025] Preferably, such as Figure 2 As shown, the spot welding coil section 2 is equipped with a tension controller 7.

[0026] Understandably, the tension controller 7 dynamically adjusts the tension of the roll material in real time to prevent material stretching or loosening caused by sudden tension changes during rewinding, eliminates accuracy fluctuations caused by machine shutdown and restart, makes the spot welding position more accurate, and significantly improves product yield.

[0027] In some specific embodiments, the spot welding module 5 includes: a transducer, an ultrasonic generator, and a variable-radius rod; wherein, An ultrasonic generator is mounted on the frame assembly 1; a variable-radius rod is connected to the ultrasonic generator, and a welding head is provided on the variable-radius rod.
