Description

Technical Field

[0001] This utility model relates to the field of hot press technology, and in particular to a hot press for windproof and breathable fabrics. Background Technology

[0002] In the field of outdoor functional fabric processing, windproof and breathable composite fabrics require the bonding of the windproof membrane to the breathable base fabric through a hot-pressing process. Traditional hot-pressing equipment has the following defects: uneven temperature distribution: unilateral heating leads to insufficient heating of the fabric, resulting in localized poor adhesion or overheating and carbonization at the interface between the windproof membrane and the base fabric, affecting composite strength and breathability; hot-pressing wrinkle defects: wrinkles are generated during the hot-pressing process due to thermal shrinkage, and existing equipment lacks a dynamic tension adjustment mechanism, resulting in poor surface smoothness of the composite fabric. To address these issues, we propose a hot-pressing machine for windproof and breathable fabrics. Utility Model Content

[0011] Beneficial effects

[0012] This utility model provides a hot press for windproof and breathable fabrics. It has the following beneficial effects:

[0013] (1) The hot press for the windproof and breathable fabric adopts a double heating structure. The first heating structure and the second heating structure heat the fabric on both sides simultaneously. The fabric is squeezed by the pressure plate and the fabric is squeezed by the rolling roller to keep the fabric in a taut state. This ensures that there is no warping at the edges during the hot pressing process and improves the flatness of the fabric after lamination.

[0014] (2) The hot press used for this windproof and breathable fabric solves the problem of uneven temperature distribution caused by traditional unilateral heating by using a two-way collaborative system of a high-frequency induction heating second heating box and an infrared radiation heating first heating box. The high-frequency induction heating rapidly heats up the metal coating of the windproof membrane, penetrating the membrane layer within 1 second without damaging the base fabric. The infrared heating radiates the base fabric at an inclined angle, making the surface temperature of the base fabric tend to stabilize, thus avoiding insufficient heating of the fabric caused by unilateral heating. This prevents localized poor adhesion or overheating and carbonization at the interface between the windproof membrane and the base fabric, which can affect the composite strength and breathability.

[0015] (3) The hot press for this windproof and breathable fabric uses a mechanical linkage design between the rolling roller and the pressure plate to achieve real-time compensation for the thermal shrinkage of the fabric, thereby reducing the generation of wrinkles. Attached Figure Description

A fixing frame 22 is fixedly installed on the upper side of the mounting block 1 corresponding to the side of the first mounting cavity 6. A pressure plate 13 is slidably installed inside the fixing frame 22. A groove 17 is opened on the upper side of the mounting block 1 corresponding to the other side of the first mounting cavity 6. A rolling roller 18 is movably installed above the groove 17. During use, the windproof fabric and the breathable fabric are combined together by the conveying structure. When heat pressing is required, the moving plate 10 moves downward, and the moving plate 10 drives the second heating box 11 downward. The second heating box 11 and the connecting plate 9 squeeze the fabric. The fabric is fully heated by the first heating structure and the second heating structure. When the moving plate 10 moves downward, it drives the pressure plate 13 to move downward to press one side of the fabric. When the rolling roller 18 moves downward, it squeezes the fabric inside the groove 17, so that the fabric is in a taut state. At this time, the first heating structure and the second heating structure squeeze the fabric to fully heat the fabric. A third connecting block 15 is fixedly installed on the side of the guide cylinder 14.

The fabric is taut under the pressure of the rolling roller 18.

[0028] The working principle of this utility model:

[0029] In use, the windproof and breathable fabrics are combined by a conveying structure. When heat pressing is required, the moving plate 10 moves downward, causing the second heating box 11 to move downward as well. The second heating box 11 and the connecting plate 9 compress the fabric. The fabric is fully heated by the first and second heating structures. As the moving plate 10 moves downward, it also causes the pressure plate 13 to move downward to press one side of the fabric. When the rolling roller 18 moves downward, it compresses the fabric inside the groove 17, keeping the fabric taut. At this time, the first heating structure and the second heating structure squeeze the fabric to fully heat it. The telescopic device 16 drives the moving plate 10 to move up and down inside the guide cylinder 14. The two rotating rollers 5 rotate in opposite directions to convey the fabric. The second connecting block 26 moves downward with the moving plate 10. The second connecting block 26 and the first slider 25 squeeze the spring 24 downward. The spring 24 squeezes the pressure plate 13. The pressure plate 13 squeezes the fabric on the connecting plate 9. The rolling roller 18 squeezes the fabric downward. The fabric is taut under the squeezing of the rolling roller 18.
