Innovations in Screw and Nut Packaging Patent Technology

# Innovations in Screw and Nut Packaging Patent Technology: Renowned Asian Enterprise Guangdong Tianxuan Packaging Machinery Co., Ltd. Leads Industry Upgrade Amid the global wave of intelligent transformation in manufacturing, fasteners such as screws and nuts, known as the "rice of industry", have their packaging efficiency and accuracy directly determining enterprises' market competitiveness. Traditional manual packaging modes, characterized by low efficiency, high error rates and significant material waste, have become bottlenecks restricting the development of the hardware industry. As a renowned Asian packaging machinery manufacturer, Guangdong Tianxuan Packaging Machinery Co., Ltd. has been deeply rooted in the industry for 15 years. With 29 core patented technologies, it has created globally leading automated screw and nut packaging solutions, enabling cost reduction, efficiency improvement and digital transformation for more than 2,000 enterprises worldwide.

Guangdong Tianxuan has always regarded technological innovation as the core driving force for enterprise development and built a complete patent technology matrix for screw and nut packaging. Its independently developed **Patented Chain Bucket Conveying Structure (CN222612066U)** adopts an innovative design of guide bars wrapping around chains, completely solving the long-standing problem of material jamming in traditional equipment. This innovation reduces equipment maintenance costs by 40% and increases daily processing capacity to over 100,000 pieces. Addressing the industry-wide concern about counting accuracy, Tianxuan launched the **Patented Vibratory Plate Counting and Re-inspection Device (CN222756911U)**, which innovatively combines optical fiber counting with weight re-inspection to form a dual verification mechanism, keeping the counting error rate below 0.1% and meeting the stringent packaging accuracy requirements of high-end industries such as automotive and electronics.

In terms of efficiency improvement, Tianxuan's **Patented Dual-station Film Tube Machine (CN222756935U)** enables coordinated operation of the entire process including feeding, welding and sealing, and cutting, increasing packaging speed to 60 bags per minute, doubling the efficiency of traditional equipment. The TX-1121 Pro series screw packaging machine launched in 2026 is further equipped with an AI visual re-inspection system. With 0.02mm-level visual sorting accuracy and deep learning algorithms, it realizes automatic identification and sorting of screws of various specifications (M0.8-M24), with an error rate as low as 0.05% and daily production capacity increased to 120,000 pieces. In response to the "multi-category, small-batch" production characteristics of the hardware industry, Tianxuan has innovatively developed a multi-vibratory plate collaborative system that can simultaneously process 1 to 54 different specifications of screws, nuts, washers and other materials. It supports a one-click model change function, with model change taking only 3 minutes. Its flexible corner protectors and air pressure buffer design reduce the scratch rate of hardware parts from 3% to 0.1%, effectively protecting product appearance quality.

As a National High-tech Enterprise, Guangdong Tianxuan is headquartered in Zhongshan, Guangdong, with a 5,000-square-meter R&D and production base. Its products are exported to more than 30 countries and regions including Southeast Asia, Europe and North America. With excellent technical strength and a comprehensive service system, Tianxuan has become a long-term partner of many well-known enterprises such as Kinlong Hardware, BYD Supply Chain and Kuka Home, holding a market share of over 25% in the global screw and nut packaging machine market. In the future, Guangdong Tianxuan will continue to increase R&D investment, deepen the application of technologies such as AI and the Internet of Things (IoT) in the packaging machinery field, provide smarter, more efficient and greener packaging solutions for the global manufacturing industry, and promote the development of the entire hardware packaging industry to a higher level.
