Positioning device capable of keeping consistent winding weight of single spindles of winder

Abstract

The invention relates to winding equipment, in particular to a positioning device capable of keeping consistent winding weight of single spindles of a winder. The positioning device comprises rotatable spindles (2) and a tensioning wheel (4) which are arranged on a rack (1), and further comprises bobbins (3) which are arranged on the spindles (2), as well as a tangential belt (5), wherein the tangential belt (5) is arranged in a straight line and is arranged between the spindles (2) and the tensioning wheel (4); and the inner side faces of the tangential belt (5) and the spindles (2) are contacted with the outer side face of the tensioning wheel (4). According to the positioning device, the tangential belt is in a complete contact with the spindles because the tangential belt is arranged in a straight line, so that the same tension on the various spindles are ensured, therefore, the rotating speeds among the single spindles are kept consistent and the inconsistent rotating speeds of the spindles are avoided; and the positioning device has good positioning effect, and the yarns which are wound on the bobbins on the spindles are excellent in size consistency; the winding weight of the single spindles of the winder are kept consistent; and the purposes of the fixed weight and knot free are realized.

Description

technical field [0001] The invention relates to a winding device, in particular to a positioning device for uniform winding weight of a single spindle of the winding machine. The invention is mainly suitable for use on yarn winding equipment, and belongs to the technical field of mechanical manufacturing. Background technique [0002] The winding machine is a common winding equipment used in the production of the wire industry. Through the winding machine, different shapes of silk blanks can be wound into bobbins with certain specifications and shapes. The winding machine is equipped with a positioning device in order to keep the winding weight of the single spindle consistent. The existing positioning device for the winding weight of the single spindle of the winding machine includes a rotatable spindle and a tension wheel arranged on the frame, and also includes There is a bobbin arranged on the spindle, and a dragon belt is also included. The dragon belt is arranged in ...

AI Technical Summary

Problems solved by technology

The positioning device with the same winding weight of a single spindle of this structure has the following defects: (1) Since the dragon belt is arranged in an arc shape, the contact between the dragon belt and the spindle is not close enough, so that the tension on each spindle is different , resulting in that the speed of individual spindles cannot be kept consistent. Some spindles have fast speeds, while others have slow speeds. As a result, the bobbins on the spindles have different sizes of bobbins after winding, and cannot achieve fixed weight and no knots. (2) Since the spindles of the winding machine are set in groups of eight, there are two tension pulleys in a set of spindles, too few tension pulleys are set and the dragon belt is set in an arc shape. The problem of the bobbin winding on the spindle makes the size of the bobbin after winding the bobbin more serious
