Description

Shuttleless Loom Waste Cloth Recycling Device

The utility model relates to a textile machine, in particular to a loom attaching machine which separates the warp yarn and the weft yarn at the side of the waste cloth of a shuttleless loom, and re-uses the warp yarn after being wound.

In the textile industry, the original old-fashioned shuttle looms are being phased out by shuttleless looms. Although the existing shuttleless looms such as rapier looms have greatly improved the production efficiency of weaving, but at the same time In the process, two waste cloth edges are produced, which causes waste of raw materials and increases the cost.

The purpose of the utility model is to provide a waste cloth edge recycling device of the shuttleless loom that separates the waste cloth edge of the shuttleless loom through the warp yarn and the weft yarn, and can be reused after the warp yarn is wound, which not only saves raw materials, but also reduces costs.

The utility model is realized in this way. It is composed of a warp yarn, a weft yarn separator, a warp yarn winder and a warp yarn winder traverse control mechanism. 1. The power input gear in the weft yarn separator is connected with a set of variable speed transmission gears through the shaft, and the four sets of waste cloth edge holding tensioning gear sets meshed with the variable speed transmission gear pass through the transmission sprocket, double sprocket and warp yarn guide The rod is connected and fixed on the housing, and the waste cloth edge holding tensioning gear set is installed at a 90° right angle with the two sets of warp and weft separation gear sets. The upper gear adopts floating pressure springs to adapt to fabrics of different thicknesses and has sufficient holding force and is respectively fixed on the shell. The gear and power input sprocket are installed on the frame through the main shaft. The yarn winding wheel and the friction wheel are frictionally driven and connected to the main shaft. The traversing gear is connected with the friction wheel traversing and reversing mechanism. Composed of gears and jaw clutches, the traversing lead screw of the winding wheel is connected with the traversing reversing mechanism by pushing the nut and fixed on the winding frame, the winding frame is connected with the pull rod, and the yarn breakage alarm is fixed on the frame. The negative electrode of the yarn breakage automatic alarm is respectively connected to the suspension plate and the contact point, and the warp winding device traverse control mechanism is installed on the friction wheel traverse reversing mechanism, and is connected with the lead screw and fixed on the frame. The traversing control mechanism of the warp winding device installed on the traversing reversing mechanism of the friction wheel of the utility model is connected with a shift fork by a pull bar, and the shift fork is contained in the shifting branch frame relative to the spring under the steel ball. After the waste cloth edge is output from the loom, it enters the warp and weft yarn separator through the edge guide device, and the two waste cloth edges are respectively tensioned by the continuous rotation of the holding tensioning gear set, and the warp yarn separated from the weft yarn passes through the guide The yarn bar sends the warp yarns into the warp yarn winder, which is driven by the friction wheel in the warp yarn winder, and the yarn winder rotates to wind the warp yarns on the yarn winder, and a group of traversing mechanisms arrange the warp yarns in traverse.

The device for recovering and processing the waste cloth edge of the shuttleless loom adopts the power of the loom to ensure synchronization with the work of the loom. As shown in Fig. 1, Fig. 2 and Fig. 3, the power is transmitted to the power input gear 5 by the waste cloth edge output gear of the loom to drive the device to work. As shown in Figure 4, Figure 5, and Figure 6, after the waste cloth edge is output by the loom, it enters the warp and weft yarn separator 2 through the edge guide 6. The selvedges are stretched separately, and the warp yarns separated from the weft yarns are sent to the warp yarn winder through the warp yarn guide rod 8. After the warp yarn and weft yarn separation gear set 9 is shifted by the speed change gear set 14, the line speed is the tension gear 34 times the line speed of group 7, through the continuous engagement and rotation of the separation gear set, the weft yarn in the waste cloth edge is bitten and separated from the waste cloth edge, and the separated weft yarn falls into the blanking basket 4 through the discharge port 10 Among them, as shown in Figure 7 and Figure 8, the duplex sprocket 16 drives the power input sprocket 27 to rotate through the chain, and drives the friction wheel 33 to rotate at the same time, and the warp yarn derived through the yarn guide rod 8 passes through the yarn guide rod 25 again, enters Winding wheel 32, winding wheel 32 rotates through the friction transmission of friction wheel 33, warp yarn is wound on the winding wheel, because traverse gear 26 and power input sprocket wheel 27 are on the same shaft, sprocket wheel 27 rotates That is to drive the traversing gear 26 to rotate together, the traversing gear 26 drives the traversing reversing mechanism 20 of the winding wheel and the traversing screw 17 to rotate, and the nut 30 is pushed to make the winding frame 28 traverse, as shown in Figures 9 and 10, Traversing around the yarn frame 28 for a certain distance will pull the reversing pull rod 21 to move, and the pull rod 21 will pull the reversing shift fork 22, and the reversing shift fork 22 will drive the displacement of the jaw clutch in the traverse reversing mechanism of the winding wheel to change the combined direction. Cause yarn wheel traversing lead screw 17 to change the direction of rotation, realize yarn wheel traversing reversing, switch branch 22 leans to one side under the action of spring 24, steel ball 23 Position, wait for the second reversing, broken yarn alarm is suspended Sheet 19 is suspended on the warp yarn, and when warp yarn breaks, suspension sheet 19 moves down, connects with contact 29, and at this moment the alarm circuit is connected, and the alarm starts to work.

By adopting the utility model, the warp yarn can be reused after being wound, and the number of times of reuse varies depending on the fiber type and quality strength of the warp yarn. The warp yarn with higher strength and quality can be reused dozens of times, which not only saves raw materials, but also reduces Reduced cost, safe to use and reliable in operation. The weft yarns separated from the warp yarn and weft yarn separator can be opened into single fibers by the yarn return opener and then spun again, which provides a feasible and good way to reduce raw material consumption for manufacturers of high-grade animal fiber fabrics Technical solutions.
