Description

Technical Field

[0001] This utility model relates to the field of composite board production technology, and in particular to a double-sided coating device for rubber composite sound-absorbing sheet boards. Background Technology

[0002] Rubber composite sound-absorbing sheets are high-performance sound insulation and vibration damping materials widely used in automobiles, construction, machinery, and other fields. They are typically composed of a metal substrate (such as cold-rolled steel or stainless steel) and a rubber layer, exhibiting excellent damping performance, oil resistance, high-temperature resistance, and impact resistance. Because the production of rubber composite sound-absorbing sheets involves hot-press vulcanization technology, hot-press vulcanization equipment is required for coating the sound insulation material. Existing coating equipment is mainly divided into single-sided multi-coating and double-sided single-coating equipment, with the double-sided single-coating equipment undoubtedly being more efficient. However, the double-sided structure of existing equipment prevents the innermost layer of sound insulation material from being effectively heated, resulting in uneven overall temperature and affecting the fusion effect. Therefore, improvements to existing equipment are needed to address these issues. Utility Model Content
