[0002] Due to the workshop's production process, silane plastic pellets require additives during packaging to ensure product quality. Each production line produces approximately 1,200 packages of finished product per day. With six production lines, each packaging station requires an oiler. The workshop operates on a two-shift system, requiring a total of 12 people, each of whom performs 600 oiling operations per day. The filling port is located inside the packaging machine, and each filling operation requires opening the packaging machine's protective door and inserting a handheld syringe into the equipment, posing a safety hazard. Furthermore, the packaging process on the production line is followed by palletizing, which is now performed by a palletizing robot, eliminating manual labor. The remaining oiling position only increases production costs. Given this reality, there is an urgent need for automated oiling equipment that can replace manual labor and reduce safety hazards and costs. Utility Model Content
