GA-type flexible towel rapier loom
GA799-1 flexible towel rapier loom is a shuttleless towel loom developed by Hangzhou Huahong Machinery Co., Ltd. based on the GA799 loom. This machine comprehensively considers the actual situation of domestic towel rapier looms and fully draws on the characteristics of foreign shuttleless towel looms. It has simple structure, high speed, high fabric quality, high weaving efficiency, low noise and low consumption. Low energy and easy maintenance. Suitable weaving varieties This towel rapier loom is mainly used to weave various spiral satin terry fabrics such as face towels, tea towels, square towels, bath towels and towel quilts using cotton yarn as raw material. Shedding mechanism The shedding mechanism adopts a top-mounted dobby, a 20-page heald frame, and a double-action semi-opening shed; or a jacquard machine or a pedal is used for shedding. The weft insertion mechanism is a double-sword single-side weft supply. It adopts a fitting connecting rod for weft insertion, a flexible rapier, and a central connection, which can accurately complete the weft insertion and leisure. Transmission mechanism: The 2kW main motor drives the loom to each mechanism through an electromagnetic brake clutch. The electromagnetic brake clutch, in conjunction with the electronic control system, can accurately control the starting, positioning, parking, inching and other functions of the loom. Starting mechanism: The raising mechanism forms the required loops by changing the beating position of the reed. The position of the reed is changed by two dedicated electromagnetic magnets, and is programmed through a computer or electric control box to complete the raising of one pile for every three and four wefts. Loops, high and low terry loops can also be made, and the structure is simple. The let-off mechanism is a positive continuous leisure device. It is mainly composed of two parts: a friction-type stepless transmission mechanism and a warp tension feedback mechanism. It also uses a special let-off clutch to complete the satin stop function. This is It can be synchronized with the weft finding, feed stop and winding stop devices of the loom to maintain constant tension on the loom. The coiling mechanism consists of a worm gear, a worm gear and a sprocket that actively and continuously drive the coiling roller to achieve continuous coiling. Weft selection mechanism The loom is suitable for single-color or 8-color fabrics. The unique weft mixing function allows irregular weft selection. Electronic weft selection is controlled by a computer so that the selected weft yarn is introduced into the shed according to the pattern design requirements. The mechanical weft selection is connected with the dobby to achieve the weft selection requirements, with simple structure and reliable use. Weft broken detection adopts piezoelectric crystal electronic sensor, which is sensitive when weft is broken or missing, and can quickly stop the machine. It also has functions such as automatic weft search and automatic weft selection. The selvage device adopts leno selvage device. Lubrication device: The main transmission wheel adopts manual centralized oil supply and automatic centralized oil supply.
