Abstract
The utility model provides a rapier loom without left refuse yarn. The rapier loom comprises a left gripper guide rail, a reed, a cloth supporting table and a weft cutting device, and is characterized in that: the weft cutting device is positioned at the front end of the left gripper guide rail close to one end of the reed; a yarn guide plate and a yarn blocking plate are additionally arranged; the yarn guide plate is parallel to the left gripper guide rail, and is arranged between the left gripper guide rail and the weft cutting device; the height of the bottom edge of the yarn guide plate decreases gradually from an end far away from the reed to an end close to the reed; the yarn blocking plate is arranged on the end part of the yarn guide plate close to the reed, and forms an included angle of 90+/-15 degrees with the yarn guide plate; the yarn blocking plate is close to the end part of the left gripper guide rail; the distance between the yarn blocking plate and the left gripper guide rail is not greater than the distance between the yarn guide plate and the left gripper guide rail; and the end part of the yarn blocking plate far away from the left gripper guide rail is provided with a yarn blocking gap which is a little higher than the cloth supporting table. In the utility model, the installation position of the weft cutting device is improved, so that the weft cutting device can be used for cutting a weft close to the cloth edge of woven cloth, and the aim of avoiding left refuse yarn during weaving of the rapier loom is fulfilled.
Description
Technical field
The utility model is a kind of arrow shaft loom that does not have left side refuse yarn of design, belongs to textile machine equipment.
Background technology
Owing to the operation principle and the clipped position of Rapier looms, the long slitter edge yarn of about 6CM is left in the left side of weaving cotton cloth when weaving cotton cloth.If with 60 calculating, every chassis can produce 127 kilograms on slitter edge yarn in 1 year, caused the wasting of resources according to 465 rev/mins of the speed of a motor vehicle, efficient 88%, yarn count.
The utility model content
Main purpose of the present utility model provides a kind of arrow shaft loom that can overcome above-mentioned defective, saving yarn, make the no left side refuse yarn of the left side slitter edge free yarn of weaving cotton cloth.Its technical scheme is:
Comprise that a left side leads the sword rail, reed, Tobe platform and Weft cutting-off apparatus, it is characterized in that: Weft cutting-off apparatus is positioned at a left side and leads the front end of sword rail near reed one end, set up guide plate and yarn retaining plate, wherein the guide plate is parallel to a left side and leads the sword rail, being installed in a left side leads between sword rail and the Weft cutting-off apparatus, the base height of guide plate is from reducing gradually to close reed end away from the reed end, yarn retaining plate is installed in the end of guide plate near reed, be 90 ± 15 degree angles with the guide plate, yarn retaining plate is led the sword rail near a left side end is not more than guide plate and the left distance of sword rail of leading with the left distance of leading the sword rail, the end that yarn retaining plate is led the sword rail away from a left side is provided with retaining yarn breach, and retaining yarn breach is a little more than the Tobe platform.
The arrow shaft loom of described no left side refuse yarn, Weft cutting-off apparatus adopts scissors, perhaps adopts the blade that is driven by micromachine.
Operation principle is: weft yarn when loom left side sword head-clamp bright pick yarn passes through the guide plate, because the gradient on guide plate base guarantees weft tension, and presses down weft yarn, makes it press close to Weft cutting-off apparatus in the wefting insertion process, and weft yarn is cut off.Lead the front end of sword rail because Weft cutting-off apparatus is positioned at a left side, guarantee that the yarn tail of staying selvedge is controlled at about 5mm near reed one end; When weft yarn finish wefting insertion, when reed is got to cloth fell, weft yarn arrives retaining yarn gap position, by the fixing weft yarn circuit of retaining yarn breach, makes weft yarn can't press close to Weft cutting-off apparatus, can not be cut off.
The utility model is owing to the installation site of having improved Weft cutting-off apparatus, and the selvedge that makes Weft cutting-off apparatus press close to weave cotton cloth cuts off weft yarn, reaches the arrow shaft loom does not have left side slitter edge yarn when weaving purpose.
Description of drawings
Fig. 1 is the part vertical view of the utility model embodiment;
Fig. 2 be embodiment illustrated in fig. 1 in the A of guide plate and yarn retaining plate to view;
Fig. 3 be embodiment illustrated in fig. 1 in the B of guide plate, yarn retaining plate and Weft cutting-off apparatus to view.
Among the figure: 1, sword rail 2, reed 3, Tobe platform 4, Weft cutting-off apparatus 5, guide plate 6, yarn retaining plate 7, retaining yarn breach 8, loom are led in a left side
The specific embodiment
In the embodiment shown in Fig. 1-3: Weft cutting-off apparatus 4 adopts the blade that is driven by micromachine, be positioned at a left side and lead the front end of sword rail 1 near reed 2 one ends, guide plate 5 is parallel to a left side and leads sword rail 1, being installed in a left side leads between sword rail 1 and the Weft cutting-off apparatus 4, the base height of guide plate 5 is from reducing gradually to close reed 2 ends away from reed 2 ends, yarn retaining plate 6 is installed in the end of guide plate 5 near reed 2, be 90 degree angles with guide plate 5, yarn retaining plate 6 is led sword rail 1 near a left side end is not more than guide plate 5 and the left distance of sword rail 1 of leading with the left distance of leading sword rail 1, the end that yarn retaining plate 6 is led sword rail 1 away from a left side is provided with retaining yarn breach 7, and retaining yarn breach 7 is a little more than Tobe platform 3.
