Description

Fixed drum type weft accumulator

Technical Field

The utility model relates to a loom sets up technical field, especially indicates a fixed drum formula weft accumulator.

Background

The modern textile industry is rapidly developing, and as an indispensable mechanical device of a textile device, a weaving machine is generally applied in the industry with high-efficiency textile efficiency and excellent textile quality, and the weaving machine device has an indispensable application of a weft accumulator. The weft accumulator is a device which is generally adopted on a shuttleless loom for adapting to high weft insertion rate and is a typical electromechanical integrated device. The weft accumulator pre-unwinds the weft from the bobbin to the storage drum by the drive of the motor, and the weft is withdrawn from the storage drum during weft insertion. After the weft accumulator is adopted, the unwinding tension of weft yarns is greatly reduced, the influence of the unwinding diameter change is eliminated, and the tension uniformity is improved. In this way, the weft accumulator can be used to store a suitable amount of weft in the weft accumulator in a good winding state according to the requirements of the weaving process, and to supply the required weft for each weft insertion.

The weft accumulator is divided into a movable drum type weft accumulator and a fixed drum type weft accumulator according to whether a yarn storage drum rotates or not, the early weft accumulator is mostly in the movable drum type, the yarn storage drum rotates around the axis of the yarn storage drum to wind weft yarns on the drum to complete the yarn winding of the movable drum type weft accumulator, the winding tension of the weft yarns is adjusted by a yarn feeding tensioner, the structure of the weft accumulator adopting the yarn winding method is simple, but the yarn storage drum of the movable drum type weft accumulator has certain rotational inertia, and the rotational inertia is in direct proportion to the square of the diameter of the drum. The larger the moment of inertia, the more disadvantageous the frequent starting and braking during the weft storage process, and therefore the drum diameter must not be too large. The number of yarn turns stored on the yarn storage drum is inversely proportional to the diameter of the drum, and the excessively small diameter brings the defect of increase of the number of stored yarn turns, and causes the problems of difficult yarn arrangement, overlapping of yarn turns, loose yarn collection and the like.
