I. Core Technical Principle:Innovative Vacuum Generation Mechanism Driven by Bernoulli Effect
The vacuum suction cup is equipped with a vacuum generation device designed based on the Bernoulli principle. It generates adsorption force through the local negative pressure formed when compressed air flows at high speed through the nozzle. No additional vacuum generator or vacuum pump is required. It can be operated simply by connecting to the existing compressed air system in the factory. This design breaks the traditional mode where vacuum suction cups rely on external equipment, significantly reducing equipment costs and energy consumption. It is particularly suitable for lightweight transformation of automated production lines.
II. Four Core Performance Advantages
1.Low vacuum, high flow rate, dynamic leakage compensation
Low vacuum environment: By precisely controlling the air pressure, a stable low vacuum adsorption force (typically <50kPa) is formed, avoiding damage to thin materials (such as the perforation or deformation of non-woven fabric in masks) caused by traditional high vacuum.
High flow rate characteristic: The internal air flow channel is optimally designed to achieve rapid adsorption and release, increasing the cycle efficiency by more than 30%, suitable for high-speed production lines (such as a production rhythm of 100-200 masks per minute in mask machines).
Intelligent leakage compensation: When the surface of the workpiece is uneven or has slight leakage, the system automatically maintains the stability of adsorption by supplementing air flow, ensuring continuous operation without interruption (compensation response time <0.5 seconds).
Zero air intake, safe separation of breathable workpieces
2.Non-contact adsorption: The air flow circulates only within the suction cup, not directly sucking in air from the workpiece, avoiding the removal of micro-particles on the workpiece surface (such as fibers of mask meltblown fabric) or causing material deformation.
Mild separation technology: Through air pressure switching, the workpiece is separated "without pulling", especially suitable for lightweight breathable materials with a weight of 25-60gsm (such as mask layers, filter core layers, medical dressings, etc.), with a damage rate of <1% (traditional suction cup damage rate is approximately 5%).
3.No equipment integration, plug-and-play
Minimal hardware configuration: No complex vacuum pipelines, sensors, or electronic control systems are required. Just one compressed air hose connection (working air pressure 0.4-0.6MPa) is needed. Installation and debugging time is reduced to one-third of the traditional solution.
Modular design: The suction cup surface can be quickly replaced according to the size of the workpiece (such as circular, rectangular, or wave-shaped), compatible with multi-variety and small-batch production scenarios (such as mask style switching, customized production of medical supplies).
4.Low energy consumption, high reliability
Energy-saving advantage: Compared to the electric vacuum pump solution, energy consumption is reduced by more than 50% (under the same adsorption force, the consumption of compressed air is approximately 0.1-0.3m³/min), suitable for long-term continuous operation in factory scenarios.
Maintenance-free structure: No moving parts wear (such as pistons, sealing rings), with a service life of over 5 years, and annual maintenance costs less than 10% of traditional suction cup systems.
