Sock Tube Knitting Machine

The working principle of the sock circular knitting machine is to weave the yarn into a tubular sock through the circular motion of the knitting needle in the needle cylinder. During the knitting process, the yarn is drawn out from the yarn tube, guided by the yarn guide, and hooked by the knitting needle. Under the action of the triangle system, the knitting needle moves up and down according to a certain rule to weave the yarn into a coil. With the rotation of the needle cylinder and the continuous movement of the knitting needle, the coils gradually increase and finally form a complete sock. At the same time, the working state of different knitting needles can be controlled by the needle selection mechanism, so as to weave socks with various patterns, designs and different structures, such as plain needle, added yarn, tuck, jacquard, terry, etc. 

Features 

With the development of technology, the operation of modern sock circular knitting machines is becoming easier and easier

Efficient production: It can knit socks quickly, greatly improving production efficiency and meeting the needs of large-scale production. Compared with manual knitting, its knitting speed can be increased by dozens or even hundreds of times.

Stable product quality: Due to the combination of mechanical and electronic control, various parameters in the knitting process can be accurately controlled, such as yarn tension, knitting needle movement trajectory, etc., thereby ensuring the quality stability of socks and reducing the defective rate.

Rich patterns: With a variety of knitting needles and needle selection functions, it can knit a variety of patterns, designs and styles of socks to meet the personalized needs of different customers. You can also design unique knitting patterns through computer programming to achieve customized production.

How to maintain the sock circular knitting machine on a daily basis

External cleaning: After work every day, use a clean soft cloth or brush to carefully remove dust, yarn debris and oil stains from the surface of the machine. Pay special attention to cleaning the outside of key parts such as the needle cylinder, cam system, and yarn delivery device to prevent these debris from entering the machine and affecting operation.
Internal cleaning: Open the protective cover of the machine regularly (recommended once a week) to clean the inside. Use a special dust blowing device to carefully blow away the dust and debris accumulated on the internal parts of the machine. Be careful to avoid strong winds blowing directly on electronic components to prevent static electricity damage. At the same time, check and clean the yarn fibers remaining in the yarn channel to avoid blocking the channel and affecting yarn delivery.

Lubrication
Key parts lubrication: According to the machine's manual, determine the key parts that need to be lubricated, such as the needle cylinder bearings, the moving parts of the cam system, the chains and gears of the transmission device, etc. Lubricate these parts with the specified type of lubricant according to the specified period (usually every 1-2 weeks).

Lubrication operation: When lubricating, ensure that the lubricant is applied evenly and in an appropriate amount. For bearings and other parts, drip or apply the lubricant to fully cover the friction surface; for chains and gears, use a brush to evenly brush the lubricant on the working surface of the chain and gear. Too much lubricant may absorb dust, and too little will not have a good lubrication effect.

Component inspection
Needle cylinder and knitting needle: Before starting the machine every day, carefully check whether the surface of the needle cylinder is worn, scratched or deformed. Check the knitting needles one by one to see if the needle hook is damaged and whether the needle body is bent. If the knitting needle is found to be damaged, it should be replaced in time to avoid problems such as missing needles and broken yarn during knitting.

Cam system: Regularly check the various triangle components of the triangle system to see if their surfaces are smooth and whether there is wear or cracks. The wear of the triangle will cause inaccurate movement trajectory of the knitting needle and affect the knitting quality. If there is a problem with the triangle, it needs to be repaired or replaced in time.

Yarn conveying device: Check whether the yarn barrel on the yarn rack is firmly installed and whether the yarn guide is worn or blocked. Ensure that the yarn is smooth and unobstructed during the conveying process without jamming or uneven tension. At the same time, check whether the tension regulator is working properly to ensure stable yarn tension.

Transmission device: Check whether the belt is loose, worn or aged. If necessary, adjust the belt tension or replace the belt in time. For chain transmission, check the tightness of the chain and clean the oil and debris on the chain. At the same time, check the meshing of the gears to ensure smooth transmission.

Electrical system maintenance
Regular inspection: Check the electrical system at least once a month. Check whether the wire connection is firm and whether there are loose, damaged or aged wires. Check the electronic components in the control box to see if there are signs of overheating or burning. For problematic wires or components found, they should be replaced in time.

Prevent static electricity and dust: Keep the inside of the electrical control box clean to prevent dust accumulation from affecting the heat dissipation and normal operation of electronic components. When operating electrical equipment, pay attention to prevent static electricity from being generated to avoid static electricity from damaging electronic components.

Replacement of wearing parts
Establish a replacement plan: According to the frequency of use of the machine and the service life of wearing parts, formulate a reasonable replacement plan for wearing parts. Common wearing parts include knitting needles, triangles, yarn guides, belts, chains, etc.
Timely replacement: When wearing parts are worn, damaged or performance deteriorates, they should be replaced in time according to the replacement process. Use original or reliable replacement wearing parts to ensure the performance and stability of the machine.
