{"product_id":"cap-inspection-and-rejection-system-for-production-line","title":"ZONESUN ZS-MD2 Automatic Cap Inspection and Rejection System For Production Line","description":"\u003cp\u003e\u003cspan\u003eThe ZONESUN cap inspection system is designed to automatically detect cap defects and induction seal liner presence after capping and sealing processes. Using contact-based inspection technology for detecting tilted caps and metal detection technology for aluminum foil liner verification, the system combines both inspection results to determine product qualification. Bottles with loose caps, misaligned caps, missing liners, or defective seals are automatically rejected into a dedicated side collection channel. The machine can be integrated with capping machines and induction sealers for automated quality control and is widely used in beverage, food, pharmaceutical, and chemical industries. Various rejection methods, including pusher-type and lane-diverting systems, can be customized according to bottle specifications and production requirements. \u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCap Inspection System Parameter \u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eMachine Model: ZS-MD2\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMachine Voltage: 220 V, 50 HZ, 550 W\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSuitable Bottle Size: Φ 40-95 mm, H 80-230 mm\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSuitable Cap Size: Φ 20-70 mm, H 20-40 mm\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWorking Capacity: ≤6800 BPH (Based on Product Size)\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMachine Size: 1500*615*1519 mm\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePackage Size: 1800*800*520 mm\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePackage Weight: 250 kg\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003e*Specifications are for reference only and may vary by your product.
