A heald frame with full carbon fiber composite structure

Abstract

The invention discloses a heald frame of a full carbon fiber composite structure. The heald frame disclosed by the invention comprises an upper cross beam and a lower cross beam which are arranged in parallel, wherein a damping interlayer A is arranged inside the upper cross beam, the two ends of the upper cross beam are respectively connected with the upper end of a side baffle A and the upper end of a side baffle B, a damping interlayer B is arranged at a joint of the upper cross beam and the side baffle A, and a damping interlayer C is arranged at a joint of the upper cross beam and the side baffle B; the two ends of the lower cross beam are respectively connected with the lower end of the side baffle A and the lower end of the side baffle B, a damping interlayer D is arranged at a joint of the lower cross beam and the side baffle A, a damping interlayer E is arranged at a joint of the lower cross beam and the side baffle B, and a damping interlayer F is arranged inside the lower cross beam. The heald frame disclosed by the invention can effectively inhibit vibration of the heald frame in a loom production process, and an inertial load of the heald frame in a high speed state is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of textile machinery and relates to a heald frame with an all-carbon fiber composite material structure. Background technique [0002] Vibration and noise problems are important factors affecting the development of high-speed looms. With the continuous increase of loom speed, new looms put forward higher requirements for the dynamic characteristics of heald frames. The vibration of the heald frame will cause the yarn to break and affect the weaving efficiency, which is extremely unfavorable for the stable operation of the loom. In the past, three generations of heald frames have been used in the shedding mechanism of looms, namely wooden heald frames, iron heald frames and aluminum alloy heald frames. These types of heald frames can work normally on ordinary looms, but they are difficult to meet the production requirements of high-speed looms For example, when the loom speed is 800r / min, the aluminum alloy ...

The vibration of the heald frame will cause the yarn to break and affect the weaving efficiency, which is extremely unfavorable to the stable operation of the loom

In the past, three generations of heald frames have been used in the shedding mechanism of looms, namely wooden heald frames, iron heald frames and aluminum alloy heald frames. These types of heald frames can work normally on ordinary looms, but they are difficult to meet the production requirements of high-speed looms For example, when the speed of the loom is 800r / min, the aluminum alloy heald frame will produce a large fatigue stress, which will lead to fatigue deformation of the heald frame structure and even frame fracture
