Buffer alarm device

Abstract

The present invention belongs to the field of the textile machinery technology, and especially relates to a buffer alarm device. Liquid is disposed in a communicating vessel formed by a first vertical slot, a transverse slot and a second vertical slot; when a roll shaft supporting base vibrates downward, a connecting rod is stretched into the first vertical slot and a pressing sheet slides clinging to the inner wall of the first vertical slot so that the liquid is extruded from the first vertical slot to the second vertical slot; because the cross sectional area of the first vertical slot is larger than the cross sectional area of the second vertical slot, if only appropriate liquid is disposed in the communicating vessel, the liquid may be pressed up to an extension tube through the second vertical slot; and when the liquid touches the preset scale of the extension tube, the alarm device is triggered to give an alarm. The buffer alarm device provided by the invention is able to preferably buffer the vibration of textile machinery components, and when the vibration amplitude of the components is excessively large, the alarm device in a device may be triggered so as to play a good role in reminding.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, in particular to a buffer alarm device. Background technique [0002] Commonly used textile machinery contains a large number of rotating parts, such as various rotating shafts, roller shafts, various wheels and so on. Ideally, these rotating parts exert the same stress on the bearings when they are rotating as when they are not rotating. However, in actual situations, due to various factors such as uneven materials, errors in processing and assembly, and asymmetrical geometric shapes, the centrifugal inertial forces generated on each particle of these parts during rotation cannot cancel each other out. The centrifugal inertial force acts on the machine through the bearing to cause vibration and noise, which accelerates the wear of the bearings of the entire textile machine and shortens the life of the machine. If the vibration amplitude is too large, it will affect the tightness of th...

However, in actual situations, due to various factors such as uneven materials, errors in processing and assembly, and asymmetrical geometric shapes, the centrifugal inertial forces generated on each particle of these parts during rotation cannot cancel each other out. The centrifugal inertial force acts on the machine through the bearing to cause vibration and noise, which accelerates the wear of the bearings of the entire textile machine and shortens the life of the machine. If the vibration amplitude is too large, it will affect the tightness of the fabric, and in severe cases cause Destructive accidents such as cloth breakage or entanglement
