Modular pneumatic feeding pendant is an automatic auxiliary feeding component developed based on modular design concept. By cooperating with pneumatic system, compressed air is used to form directional airflow, and materials such as granules, tablets, capsules and small parts are stably and accurately transported to the next working procedure (such as metering, packaging and assembly). The product adopts articulated structure, which can be directly installed on standard modules (such as aluminum profile frame, conveying line, equipment frame), with convenient disassembly and assembly, and is suitable for various production line layouts.
