Description

Technical Field

[0001] The invention relates to an inverted shaft damping steel belt device for a sectional warping machine, belonging to the technical field of textile machinery. Background Art

[0002] In the past, the inverted shaft damping steel belt device of the sectional warping machine was Figure 1 As shown, it includes a large cage steel ring 1, a damping steel belt 2, a steel belt movable end joint 3 and a steel belt fixed end joint 4. The tension of the slitting warping machine is controlled by the damping steel belt 2, which is wrapped on the steel rings 1 at both ends of the large cage. During warping, the steel belt movable end joint 3 is lifted upward, the damping steel belt 2 is relaxed, and a certain gap is maintained with the large cage steel ring 1, which does not affect the rotation of the large cage; during the axis reversal, the steel belt movable end joint 3 falls downward, the damping steel belt 2 is tightened, and the large cage steel ring 1 is contacted and rubbed to prevent the large cage from rotating, thereby providing tension to the yarn. The yarn tension is determined by the friction between the damping steel belt and the large cage steel ring. Friction generates heat and friction generates noise. This is common knowledge in physics. This method of providing tension to the yarn by friction between the damping steel belt and the large cage steel ring is inevitable to generate noise. This noise is particularly obvious during high tension axis reversal, which brings customers an unbearable sensory experience.

[0003] Although it is impossible to eliminate noise fundamentally, we are facing the task of reducing noise as much as possible and keeping the friction sound between the damping steel belt and the large cage steel ring within an acceptable range. After many tests, we found that the noise would be reduced by pressing the part of the steel belt where the noise is obvious. The reason was analyzed and found that because the asbestos brake belt of the damping steel belt is made of a harder material, it cannot fit perfectly with the steel ring when it is bent and wrapped on the large cage steel ring. The contact surface in some local positions is small and gaps appear. The damping steel belt at the gap resonates during friction, which is the main reason for the noise. Pressing the steel belt by hand will increase the contact surface between the damping steel belt and the large cage steel ring, eliminate local gaps, destroy the resonance of the damping steel belt, and achieve the effect of reducing noise. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a reverse-axis damping steel belt device for a slitting warping machine in response to the above-mentioned prior art.
