As a reliable manufacturer, factory and professional supplier based in China, Shilong Machinery will walk you through its full operating flow. The whole closed‑loop operation consists of seven procedures: bottle feeding and separation, cap sorting and delivery, bottle positioning and clamping, automatic cap loading, servo‑driven capping, defective‑product inspection and rejection, and finished‑product discharge. All operations are automatically controlled by PLC and photoelectric sensors with zero manual operation.

As a professional manufacturer & supplier from China, our machine is mainly designed for thread‑structured caps. Ordinary plastic thread caps, anti‑theft thread caps (break‑ring anti‑theft caps commonly used for oral liquids and disinfectants). Spin‑on thread caps and partial combined thread caps with inner plugs. Not applicable: Stopper press‑in caps, snap‑on caps, aluminium roll‑on caps (aluminium caps for oral liquid). Cap size: standard φ18‑60 mm; larger sizes available upon custom request from our factory.

1. Control System (Core Electric Control) ✅ Standard Configuration PLC programmable logic controller 7-inch color touch screen (Chinese & English interface, multi-formula storage, output statistics, fault alarm display) Photoelectric bottle detection sensor: No filling without bottles Low-voltage electrical components for the whole machine (well-known domestic brands; Siemens available as upgrade option) Emergency stop button, operation indicator light, sound & light fault alarm Parameter encryption authority management, filling counting function ❇️ Optional Configuration Remote communication module (for remote commissioning support) Complete explosion-proof electric control system (for chemical solvents) Data export function (export filling records via USB flash drive)

The overall process consists of five major stages: Bottle Feeding & Conveying → Automatic Cap Sorting & Cap Placing → Bottle Positioning → Capping & Tightening → Finished Bottle Discharging. Models with different structures share the same front-end conveying and cap sorting process. The core difference lies in the capping actuator, which will be explained separately below.

The complete machine consists of four continuous working procedures: bottle conveying & separating, automatic cap feeding, servo torque screw capping, inspection & discharging. Its core is closed-loop torque control via servo motor, which precisely controls the screw tightening force.

The complete workflow consists of seven closed-loop automatic procedures: bottle feeding & separating, cap sorting & feeding, bottle positioning & clamping, automatic cap placing, servo capping, defective product detection & rejection, and finished product discharging. The whole system adopts PLC photoelectric automatic induction control with no manual intervention required.
