Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of suede buffing machine, specifically to a buffing machine for microfiber leather production. BACKGROUND

[0002] In the production process of microfiber leather, surface buffing treatment is one of the key steps to improve product texture and hand feeling. The traditional manual buffing method is low in efficiency and difficult to ensure the uniformity and consistency of buffing effect. Therefore, mechanized and automated buffing equipment has gradually become the industry mainstream.

[0003] For example, a "buffing machine for microfiber suede production" (patent publication number CN219010793U) is proposed in Chinese patent. The device performs single-side buffing treatment on microfiber leather by rotating the buffing roller, effectively improving production efficiency. The above-mentioned patent can realize different degrees of buffing effect on the surface of microfiber leather by adjusting the speed and pressure of the buffing roller, thereby meeting the needs of different customers. However, the above-mentioned patent only solves the problem of single-side buffing and does not consider the problem of double-side buffing and cleaning and dust handling during the buffing process. After single-side buffing, the other side of the microfiber leather often needs additional treatment, which not only increases the production cost, but also may cause inconsistent buffing effect on both sides due to improper treatment, affecting the quality of the final product.

[0004] In addition, the existing buffing equipment often produces a large amount of dust and lint during buffing. If these impurities are not cleaned in time, they will not only pollute the working environment, but also may adhere to the surface of the microfiber leather, affecting the buffing effect and subsequent processing. Although some equipment is equipped with a simple dust collection device, the dust collection effect is limited, and additional cleaning is often required after buffing, reducing the overall production efficiency. Therefore, we propose a buffing machine for microfiber leather production. UTILITY MODEL CONTENTS
