With these advanced functions, the daily production capacity of this model exceeds 400 pairs, which can quickly respond to market demand and bring higher economic benefits to the enterprise.
Energy-saving design: The application of servo motors is the key to the energy-saving design of sock machines. The servo motor can dynamically adjust the power according to the actual operation of the machine, avoiding the energy waste caused by the fixed power of traditional motors during operation. Compared with traditional models, energy consumption is reduced by 30%, which not only saves a lot of production costs for the enterprise, but also meets the requirements of today's society for energy conservation and environmental protection. With a single machine daily power consumption of only 3.6kW, the energy-saving effect accumulated over a long period of time is significant in the case of large-scale production, which is of great significance to the sustainable development of the enterprise.
Multi-system collaboration: The multi-system collaborative working mode of the three-needle cylinder machine is another important manifestation of the efficient production of the sock machine. This machine can simultaneously complete the sock ribbing, sock body and toe reinforcement processes, making the sock production process smoother and more efficient. The knitting of the sock ribbing can provide appropriate elasticity to ensure that the socks are not easy to slip off; the knitting of the sock body determines the comfort and beauty of the socks; the toe reinforcement process enhances the wear resistance of the socks and extends the service life of the socks. Through the collaborative work of multiple systems, the waiting time between processes is reduced and the overall production efficiency is improved.
2. Process accuracy and adaptability
German precision needle rail system with photosensitive yarn detection device: The German precision needle rail system is known for its high precision and stability. With the photosensitive yarn detection device, it provides a strong guarantee for the process accuracy of the sock machine. The photosensitive yarn detection device can monitor the status of the yarn in real time. Once the yarn is broken or abnormal, it can respond quickly and stop the machine operation, avoiding the production of defective products caused by yarn problems. The thread breakage rate is less than 0.3%. This extremely low thread breakage rate greatly improves the continuity of production and the qualified rate of products, and reduces the waste of raw materials and production time.
The 200-needle high-density model can knit 600D ultra-thick hiking socks, and the needle pitch adjustment range is 0.5-3.0mm: The emergence of the 200-needle high-density model enables the sock machine to meet the production needs of socks of different thicknesses and materials. 600D ultra-thick hiking socks have extremely high requirements for needle pitch and knitting density. The 200-needle high-density model can perfectly knit this high-quality hiking socks with its powerful knitting ability.
Operation and maintenance cost control
The modular design shortens the needle cylinder replacement time to 10 minutes and reduces the maintenance cost by 45%: Modular design is an important innovation in the operation and maintenance cost control of sock machines. Traditional sock machines often require a lot of time and manpower when replacing needle cylinders, while modular design makes needle cylinder replacement simpler and faster. By designing the syringe as an independent module, the operator can complete the replacement of the syringe within 10 minutes, which greatly reduces downtime and improves production efficiency. At the same time, the modular design also makes maintenance more convenient. Each module can be repaired and replaced independently, reducing the difficulty and cost of maintenance. The maintenance cost is reduced by 45%, which is a considerable saving for the company and improves the company's market competitiveness.

3.How to choose a sock machine suitable for your company?
Clear production needs
Production scale: Enterprises should determine the required sock machine output based on their own order volume and market expectations. If the order volume is large and stable, you can choose a high-output sock machine, such as some high-speed fully automatic sock machines, which have a high rotation speed per minute and can produce hundreds of pairs of socks per day, which can meet the needs of large-scale production; for enterprises with small order volumes or in the start-up stage, you can first choose a sock machine with moderate output to avoid idle equipment and waste of resources.
Product type: Different sock machines are suitable for producing different types of socks. If you mainly produce ordinary cotton socks, the functional requirements for the sock machine are relatively simple, and the basic knitting function can be met; if you want to produce high-end or special-function socks such as medical pressure socks and seamless sports socks, you need to choose a sock machine with corresponding special functions, such as a sock machine that supports seamless knitting technology and can accurately control pressure distribution.
Product quality requirements: For enterprises with high requirements for sock quality, such as producing high-end brand socks or export products, you need to pay attention to the knitting accuracy, stability and consistency of the sock machine. High-precision sock machines can produce socks with clear patterns, uniform stitch lengths, and accurate sizes, reducing the defective rate. For example, some sock machines equipped with German precision needle rail systems and advanced sensors can effectively guarantee the quality of socks.
