Type structure and technical specifications of tuck-in device

1. Type (1) According to the type of loom equipped: rapier loom, projectile loom and air-jet loom, etc. (2) According to the purpose: used for weaving conventional fabrics and weaving special fabrics, such as industrial fabrics with very sparse weft density. (3) According to the width of the door used: for narrow width, there are only one fold-in edge for the left and right hands; for wide width, there are not only one fold-in edge for the left and right hands, but also one or even multiple middle fold-in edges. 2. Structure and Leisure Principle The fold-in edge device can be divided into four parts: connection, transmission, box and execution. The connecting part fixes the fold-in edge to the corresponding position on the loom, and the transmission part transmits the power from the loom to the fold-in edge. edge. Connections and transmissions vary depending on the loom used. There are many models of tuck-in devices due to different uses and types of looms, and the structures are also different. However, the fold-in edge device is mostly used for weaving fine woolen fabrics on rapier looms. Therefore, the following takes the fold-in edge used on the Tianma excellent loom produced by SOMET Company as an example to illustrate the structure and principle of its box and executive components. This set of devices consists of two fold-in edges, left and right, which are placed on both sides of the fabric edge and used in pairs. Figure 3-2 shows the weft insertion and edge folding device.
There are 4 sets of conjugate cams in the box 1, which control the axial reciprocation of the crochet shaft 2, the presser foot shaft 3, the scissor shaft 4 and the movement of the crochet shaft, crochet hook 6, and the presser foot through the swing arm and the connecting rod. 7 and scissors 5 and other actuators are installed on three axes respectively, and are driven by the three axes to perform pressing, shearing, hooking and other actions. After the introduced weft yarn is beaten by the steel reed and woven by the side warp yarn, the presser foot 7 extends out to clamp the weft yarn, and then the weft yarn is cut by the scissors 5 at a distance of about 11mm from the first warp yarn between the weft scissors and the side warp yarn. Cutting, when the weft yarn is clamped and cut, the crochet hook 6 also rotates between the upper and lower openings. As the crochet hook and the presser foot seat are relatively relaxed, the weft yarn is hooked by the crochet hook, and the weft yarn head follows the crochet needle from the presser foot seat. Bring in selvage. Although the external dimensions of the tuck-in device used on other rapier looms are different from the tuck-in device used on the Tianma loom introduced above, there are also 4 sets of cam mechanisms in the box, but the form of the cam is different. For example: the folding edge of the GTM machine is a groove cam, the SM93 machine is a cylindrical cam, and the FAST machine is a disc radial cam. Their ultimate purpose is to drive three axes to perform corresponding actions, and other folding edge execution components There are also scissors, presser feet and crochet hooks. Although the shapes are slightly different, the final action process is similar. 3. Technical Specifications (1) Mounting type: Top mounting type (one fabric edge on each side, and the middle fold-in edge is in the middle of the door width). (2) Applicable speed: for rapier machine, ≤430r/min; for jet machine, ≤600r/min. (3) Width of folded edge area: ≥14mm. (4) Power: The various folded edges are basically the same, about 0.1kW (at 430r/min, one side).
