In the hardware fastener industry, the demand for mixed packing of hex head screws and lag bolts is surging. Whether in furniture assembly, machinery manufacturing, or architectural decoration, clients increasingly prefer "all-in-one" screw kits rather than purchasing components separately. However, mixing screws of different shapes and specifications poses high demands on the precision, stability, and intelligence of packaging equipment. Leveraging 15 years of technical expertise and 29 core patents, Guangdong Tianxuan Packaging Machinery Co., Ltd. provides an industry-leading mixed packing solution.

Tianxuan has independently developed a "Fiber Optic Counting + Dynamic Weighing + AI Vision" triple-inspection system, reducing counting errors to below 0.01%—tripling the accuracy of traditional equipment. This perfectly solves the pain point of high error rates caused by the significant shape differences between hex screws and lag bolts.
Regarding hardware structure, Tianxuan holds the "Chain Bucket Conveying Structure Patent (CN222066066U)", which completely eliminates material jamming during the conveying of irregular screws. The equipment features a detachable drag bucket module; enterprises can configure multiple preset buckets to achieve rapid material changeovers, perfectly suiting modern production models requiring "small batches and multiple varieties."

The newly launched TX-1121 Pro series boasts 0.02mm visual sorting accuracy and deep learning algorithms, supporting automatic identification and sorting for M0.8-M24 full-spec fasteners. With a daily capacity of up to 120,000 pieces and a packaging speed of 220 packs per minute, it achieves "high speed without sacrificing accuracy."
Its modular design allows for quick changeovers in just 8 minutes, compatible with the mixed packaging of screws, nuts, washers, and more. For mixed packing scenarios involving hex screws and lag bolts, the intelligent PLC control system allows preset configurations, storing 10-20 different kit formulas for one-click switching without repeated debugging.
Tianxuan’s Intelligent Formula Management System is the core advantage distinguishing it from standard packaging machines. Operators simply set the specific quantities of hex screws and lag bolts per pack on the touchscreen, and the machine automatically completes the entire process—from multi-channel feeding and precise counting to mixed bagging. The system supports "formula memory," storing multiple kit configurations to significantly enhance production flexibility.
As a National High-Tech Enterprise and Vice Chairman Unit of the China Food and Packaging Machinery Industry Association, Tianxuan products have passed 12 international certifications, including EU CE, US FDA, and German TÜV, exported to over 50 countries and regions.
Currently, Tianxuan serves more than 6,000 enterprises, including Hisense Air Conditioning, BYD, and Foxconn. Real-world data shows: After a certain auto parts manufacturer introduced Tianxuan’s production line, capacity increased from 200 packs/hour to 800 packs/hour, and labor costs dropped by 60%. An electronic component manufacturer adopting the AI vision counting system achieved 80 combo sets per minute with near-zero error rates, slashing customer complaints by 90%.
The mixed packing of hex head screws and lag bolts may seem simple, but it tests a machine's adaptability to material shapes, precise counting capabilities, and intelligent management of production rhythms. With 15 years of industry dedication, 29 core patents, and the backing of 6,000+ enterprise partners, Tianxuan Packaging provides a truly "zero-error, high-efficiency, low-cost" top-tier mixed packing solution.
