Abstract
Description
[Technical Field]
[0001] This utility model relates to an online sock knitting device using nylon DTY. [Background Technology]
[0002] Currently, after nylon yarn spindles come off the production line, they first undergo a series of quality inspections, including appearance inspection, single-spindle yarn reeling, and sock dyeing and inspection. Among these, the sock knitting process is labor-intensive and slow, mainly due to the following reasons:
[0003] 1. After the yarn spindle comes off the machine, it must first be balanced on the line before it can be knitted into socks one by one. This process requires manual recording of the balancing time and manual location of the target yarn spindle, which is slow and the balancing time of the yarn spindle is inaccurate, resulting in unstable quality when knitting and dyeing socks.
[0004] 2. The offline management of the silk-threading machine involves manual pushing and pulling, which is labor-intensive, inefficient, and has a high risk factor.
[0005] 3. When knitting socks, when the yarn sewing machine finishes knitting one side of the sock, it needs to be manually rotated to knit the other side. Adjacent yarn sewing machines are prone to colliding, which is dangerous and slow, affecting the efficiency of sock knitting.
[0006] It is evident that current hosiery production using nylon DTY yarn largely employs traditional manual or semi-automatic production lines, which generally suffer from low production efficiency and high labor costs, failing to meet the needs of large-scale production. While semi-automatic or fully automatic production lines offer slightly improved efficiency, most have complex structures, unreasonable equipment configurations, and poorly planned and connected production lines, resulting in an overall inefficient production process that impacts both production efficiency and product quality. Furthermore, they require a large footprint and incur high maintenance costs, making them unsuitable for small and medium-sized enterprises.
[0007] Therefore, it is necessary to develop and design an online sock knitting machine using nylon DTY to solve the problems of complex structure, unreasonable configuration of various equipment, unreasonable planning and connection of production line process, which leads to an unsmooth overall production process, affecting production efficiency and product quality, and also has a large overall footprint.
