Description

Technical Field

[0001] The utility model relates to the field of circular looms, in particular to a yarn tensioning device for a circular loom. Background Art

[0002] A circular loom is a commonly used device in the textile industry, mainly used for weaving tubular cloth. The working principle of this device is that the warp yarns are provided by the yarn spindles on the warp beam. These warp yarns are cross-opened by the heddle frames of the warp yarns before entering the circular loom, and the weft shuttle makes a circular motion through the warp yarns in the cross-opening, thereby weaving into tubular cloth. However, there are some problems with the existing circular looms in terms of yarn tensioning. Since the yarns may become slack or overly tensioned during the weaving process, this may lead to quality problems in the woven tubular cloth, such as wrinkles, slackness, or over-tightness. Therefore, it is necessary to provide a new type of yarn tensioning device for a circular loom, which can effectively solve the above problems and improve the weaving quality. Summary of the Utility Model

[0014] All the features disclosed in this specification, or all the steps in any disclosed method or process, except for mutually exclusive features and / or steps, can be combined in any manner.

[0015] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless specifically stated otherwise, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated otherwise, each feature is only an example of a series of equivalent or similar features.

[0016] A yarn tensioning device for a circular loom, comprising a housing 1, on which a plurality of tension control devices 2 are arranged for controlling the tension of two yarns; one of the tension control devices 2 is arranged at the central position of the housing 1, and tension control devices 2 with opposite settings are symmetrically arranged on both sides thereof, forming an M-shaped structure, which can more finely adjust the height difference of the yarn. In a compact space, the design of the M-shaped structure enables the tension control devices to be efficiently arranged, saving space; the tension control device 2 includes a wire guide pulley 3, the wire guide pulley 3 is arranged in the housing 1 through a lifting rod 4, a vertically movable adjusting rod 5 is arranged at the bottom of the lifting rod 4, and springs 6 are connected between the two ends of the lifting rod 4 and the adjusting rod 5. By moving the adjusting rod 5 up and down, the position of the wire guide pulley 3 can be adjusted, and thus the tension of the yarn can be adjusted; an adjusting frame 7 is arranged on the outer side of the housing 1 at the position of the spring 6, and an adjusting hanging rod 51 matched with the adjusting frame 7 is arranged on the adjusting rod 5, and the adjusting hanging rod 51 is fixedly arranged at both ends of the adjusting rod 5.
