Problems solved by technology

When the creel is used to let off the warp, due to the large number of warp yarns, it cannot meet the independent movement of each bobbin to actively send the warp yarn out
Therefore, the warp let-off of the creel is mostly passive, mainly relying on the traction force of the take-up device to pull the yarn out of the bobbin, which increases the load of the take-up device and the friction damage between the yarn and other devices

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. The operating methods not indicated in the following examples are generally in accordance with conventional conditions, or in accordance with the conditions suggested by the manufacturer.

[0037] Such as figure 1 As shown, the active warp let-off device of the three-dimensional loom in this embodiment includes three roller turning devices 1 arranged at equal intervals longitudinally and parallel to each other, and a yarn dividing device is provided on the back of each roller turning device 1 2 Coordinating with it, the three roller turning devices 1 rely on the belt transmission device 3 arranged on its side for transmission.

[0038] Such as figure 2 As shown, the yarn splitting devi...

Abstract

The invention discloses an active let-off device of a three-dimensional loom. The device comprises a plurality of roller rotating devices which are longitudinally arranged and are parallel to each other in pairs, wherein a yarn splitting device is arranged on the back surface of each roller rotating device, and a belt transmission device is arranged on the side surface of each roller rotating device. The invention further discloses a using method of the active let-off device of the three-dimensional loom; yarn is divided by the yarn splitting devices and then actively sent out through the roller rotating devices under the driving of the belt transmission devices.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an active warp let-off device and method for a three-dimensional loom, and is especially suitable for three-dimensional looms that use creel let-off to weave three-dimensional fabrics with a large number of warp yarns. The structure is simple and easy to use. Background technique [0002] Three-dimensional textile technology is an extension of traditional textile technology. There are more three-dimensional looms at present, such as the patented technologies of CN101294327A and CN104294464A as publication numbers. [0003] Compared with the traditional two-dimensional fabric, the three-dimensional fabric adds yarns in the Z direction in addition to the yarns in the X and Y directions of the plane, and the yarns in the three directions are interwoven to form an overall fiber network structure, which has good The integrity and stability of the material have significantly improved...
