It is mainly divided into loose winder and tight winder. The loose winding machine is a groove drum winding machine for winding loose bobbins. A larger yarn winding Angle (such as 55°) is used, and a winding tension decreasing device and winding pressure decreasing device are equipped, so that the winding density of the bobbin is reduced and the inner and outer layers are uniform. Loose bobbins are used for bobbin dyeing. The simple tubes are made of light metal with many holes in the wall. There are also spring bobbins made of stainless steel wire to facilitate the dyeing liquid to penetrate the yarn layer through the tube wall and ensure uniform dyeing inside and outside the bobbin.Each spindle of the compact winding machine is driven separately by a motor, equipped with a set of automatic joint device. In addition, this type of machine is also equipped with advanced electronic yarn cleaner, air splicer or mechanical splicer, electronic length fixing device, anti-stack device, metal groove cylinder, horizontal spring pressure tension device without column core, waxing device, air ring control device, circuit blowing cleaning device, etc., to ensure the excellent quality of the cylinder.
According to the degree of automation of winding operation, it is divided into semi-automatic winding machine and automatic winding machine and fine cylinder combined machine.The semi-automatic winder can only complete the winding of the bobbin, the automatic stop of the broken ends and the yarn cleaning and defect removal.The fine cylinder combined machine connects the spinning frame and the automatic winding machine with the manipulator and the automatic transport line, shortens the working procedure, reduces the manpower, and is beneficial to the production management and the product quality improvement.
