Description

Technical Field

[0001] This utility model belongs to the field of cutting equipment technology, and in particular relates to a partitioned adsorption device for a cutting platform and a cutting device. Background Technology

[0002] In industries such as garment manufacturing, footwear, luggage, and furniture decoration, flexible cutting equipment is needed to cut flexible materials such as leather and fabric. Vacuum adsorption cutting platforms are an indispensable part of these cutting devices. The basic principle is to use a fan (usually a vacuum pump or a high-power centrifugal fan) to generate negative pressure under the cutting platform. This pressure, through numerous adsorption holes on the platform, firmly adsorbs and fixes the material placed on the platform, preventing displacement during cutting and ensuring processing accuracy and quality. Currently, for large-size cutting machines, the cutting platform typically adopts an integrated vacuum adsorption design. This means the entire platform is located beneath a large, interconnected cavity or multiple cavities connected by pipes, with one or more high-power fans providing the adsorption force. This design provides stable and reliable adsorption when processing large areas of material that can completely cover the platform. However, this integrated adsorption design has certain drawbacks in practical applications, especially when processing small materials or materials that cannot completely cover the effective adsorption area of ​​the platform: when the size of the material being cut is much smaller than the cutting platform, the material can only cover part of the adsorption holes on the platform. At this point, the blower continuously operates to create a vacuum, but because a large number of adsorption pores are exposed to the air and not covered by the material, it is difficult to form and maintain a sufficient negative pressure inside the platform (insufficient vacuum). Air rushes in through these uncovered pores, severely weakening the adsorption force in the material-covered area. This prevents the material from being effectively and stably adsorbed and fixed, making it prone to slippage or displacement during cutting, severely affecting cutting accuracy, and even leading to material scrap or tool damage. To overcome this air leakage problem and attempt to achieve a certain adsorption effect, integrated adsorption designs often rely on very powerful blowers. Even when processing small parts with most adsorption pores exposed, the blower must operate at full load for extended periods to try to compensate for the large leakage. Continuous high-power operation not only consumes electricity but also increases blower wear and maintenance costs. This high energy consumption and low efficiency problem is particularly prominent in scenarios requiring frequent switching between processing different sized materials, especially in small-batch, multi-variety production.
