Neutral Pen Refill Assembly Machine Solution

The one-four-point gel pen refill assembly machine is a highly efficient automated device specially designed for the batch production of gel pen refills. With four-station synchronous operation as its core, it can precisely assemble components such as the ink tube, steel ball head, and tail stopper of the pen refill simultaneously. It is widely used in stationery manufacturing enterprises and significantly improves the efficiency of pen refill assembly. ​ The equipment adopts a modular assembly structure. Four independent workstations correspond respectively to the feeding, pressing, inspection and discharging processes. The components are synchronously transmitted through the precision guide rails driven by servo motors, with a positioning accuracy of ±0.02mm. This ensures that the coaxiality error between the steel ball head and the ink tube is ≤0.03mm, avoiding ink leakage or poor ink discharge. ​ It is compatible with various gel pen refill specifications with lengths ranging from…
