Abstract

The invention relates to an anti-loosening alarm device for screen cloth of a vibrating screen. The anti-loosening alarm device comprises a screen cloth fixing and supporting frame, a screen cloth tensioning device and a screen cloth compressing spring, wherein a micro-measuring sensor is arranged between the screen cloth fixing and supporting frame and the screen cloth tensioning device, and a detection alarm circuit is connected to the signal output of the micro-measuring sensor. Compared with the prior art, the anti-loosening alarm device can be used for monitoring the pull force looseningsituation of the screen cloth of the vibrating screen or the warp breakage situation of the screen cloth in real time by utilizing the micro-measuring sensor, outputting an alarm signal by virtue of the detection alarm circuit in real time, accurately judging whether the screen cloth of the vibrating screen is loosened or the warps of the screen cloth are broken under the condition of not openinga shell of the vibrating shell to inspect the screen cloth, and reminding an operator of increasing the tension force of the screen cloth in time, thereby prolonging the service life of the screen cloth and reducing the mixed screening rate by replacing the screen cloth in time.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an anti-loosening alarm device for a vibrating screen. Background technique [0002] During the use of the existing vibrating screen, the screen is often loose. If the screen is not tightened to the required tension in time, the warp of the screen is prone to breakage. When the warp of the screen is broken, the mixed screen rate rises. At present, the current method to solve this problem is to have a person observe the screen regularly according to the experience of use, or observe the situation of the screened material, and then decide whether to tighten the screen or replace the screen. However, this method is easy to be difficult to accurately judge when the screen is loose or the warp of the screen is broken due to the negligence of personnel or the different materials to be screened. Contents of the invention [0003] The main purpose of the present invention is to o...
