As the air pump rotates, it generates negative pressure to create a vacuum airflow; material is drawn into the suction nozzle and conveyed through the suction pipe into the loader's hopper. A filter completely separates the material from the air. When the hopper is full, the controller automatically cuts off the power, stopping the vacuum loader; simultaneously, the hopper discharge door opens automatically, allowing the material to drop into the equipment's hopper. At the same time, compressed air automatically cleans the filter via a pulse back-blowing valve.The automatic feeder starts up when the preset time is reached or the material level sensor signals a need for material. It offers advantages such as a simple, compact structure, maintenance-free operation, low noise, ease of control, static electricity elimination, and GMP compliance. Utilizing a high vacuum generated by a rotary air pump, the system conveys materials effectively while preventing stratification and ensuring the homogeneity of mixed ingredients. It is the preferred automatic feeding solution for machinery such as non-woven fabric equipment, tablet presses, capsule fillers, dry granulators, packaging machines, pulverizers, and vibrating screens.Due to the multi-directional motion of the mixing vessel, materials inside undergo extensive cross-mixing, resulting in superior mixing performance and a uniformity rate exceeding 99.9%. It offers a maximum loading coefficient of 0.9 (compared to 0.85 for standard mixers), along with short mixing times and high efficiency. The mixer features a uniquely designed vessel with finely polished interior walls—eliminating dead zones and preventing material contamination—while also ensuring convenient discharging, easy cleaning, and simple operation.We previously mentioned that the vacuum feeder offers highly precise positioning; this is due to the influence of various contributing factors. So, what exactly are these factors?
1. The influencing factors vary depending on the positioning method. For instance, when using mechanical stops for positioning, accuracy depends on factors such as the rigidity of the stop and the speed at which contact is made with it.2. Positioning speed significantly affects positioning accuracy. This is because the amount of energy from moving parts that must be dissipated varies depending on the positioning speed. Generally, positioning speed should be appropriately controlled to minimize positioning errors—for instance, by enhancing the damping performance and efficiency of the cushioning mechanism, and by regulating the drive system to decelerate the moving parts at the right moment.3. The manufacturing, installation, and adjustment precision of the robotic manipulator directly affects its positioning accuracy.
4. Weight of moving parts: The weight of moving parts includes the mass of the manipulator itself and that of the object being grasped. Variations in the weight of moving parts significantly impact positioning accuracy; generally, an increase in weight leads to reduced positioning accuracy.
Therefore, the design process must not only aim to minimize the weight of the moving components themselves but also account for the effects of load variations during operation.5. Position control accuracy differs among on/off control, electro-hydraulic proportional control, and servo control systems. This is due not only to variations in the precision and sensitivity of the respective control components but also to the presence or absence of a position feedback device.
Currently, pillow-style bag packaging is seeing increasing adoption across sectors such as pharmaceuticals, health supplements, and food products, thanks to advantages such as simplicity, portability, ease of use, and material efficiency. Consequently, pillow-style bag packaging machines—the fundamental equipment for producing these bags—are finding increasingly widespread application. As the technology behind these machines matures and their usage expands, the selection of the appropriate feeding method has become a key focus for manufacturers. This article primarily discusses the feeding methods used for solid powdered materials in pillow-style bag packaging machines.Domestic methods for feeding solid powdered materials have evolved through several stages: from the earliest manual ladder-climbing and dumping to conveyor belts; from bucket elevation to positive-pressure conveying; and from standard vacuum conveying to automated vacuum conveying, alongside multi-floor pneumatic gravity-feed systems. This progression reflects the advancements made in material feeding methods over time.Currently, the domestic packaging process for pillow-style bags still largely relies on manual methods—specifically, workers climbing ladders to pour in materials. The primary reasons for this are:
The hoppers of multi-lane pillow-style bag packaging machines are rectangular, making it difficult to achieve a uniform material thickness;
Existing multi-lane packaging machines are quite tall; height constraints in established workshops prevent the use of hopper-loading systems, while adopting such systems in new facilities increases cleanroom height requirements and raises operational costs.
