A method for quickly tightening the screen and preventing the screen from falling, and a vibrating screen

Abstract

The invention relates to a method for quickly tightening screen cloth and preventing the screen cloth from falling. Screen frames and the screen cloth are adopted in the method. The method is characterized by comprising the following steps that firstly, the screen cloth is laid flat on the upper end face of the lower screen frame; afterwards, the screen cloth is connected with the top of a central supporting column; next, the upper screen frame is vertically placed down, the edge of the screen cloth is bent downwards through a cloth pressing ring on the upper screen frame, and then the edge of the screen cloth is laid flat between an upper screen frame flange and a lower screen frame flange; after that, the upper screen frame flange and the lower screen frame flange are fastened into a whole through a V-shaped lacing ring; finally, a lifting jack is controlled to drive a tightening ring to move upwards to abut against the screen cloth, so that the screen cloth is installed and tightened. The method has the advantages that the cloth pressing ring is fixedly arranged at the lower portion of the upper screen frame, the edge of the screen cloth is bent downwards and then bent upwards through the cloth pressing ring, and therefore the effect of further tightening the screen cloth can be achieved; besides, the edge of the screen cloth is not prone to looseness through two times of reverse bending.

Description

technical field [0001] The invention belongs to the technical field of material screening, and in particular relates to a vibrating screen. Background technique [0002] Enterprises widely use vibrating screens to sort materials. Commonly used vibrating screens include structural components such as upper screen frame, lower screen frame, grid frame, screen mesh, spring connected to the screen frame, vibration motor, etc. The screen is vibrated by starting the vibrating motor, so that the small particles pass through the screen and leak down, and the large particles are blocked on the screen. The screen used in the vibrating screen is generally woven with metal wire, nylon wire, etc. The process of tightening the screen mesh in the prior art is as follows: [0003] (1) Apply a new square screen on the grid, flatten the screen and bend it, so that the screen is bent and pasted on the outer wall of the grid; [0004] (2) Tighten the lower screen with the pressure ring first...

Problems solved by technology

The longer it takes to replace the screen, the greater the impact on production

[0008] In the industry, there has been no good solution for quick tensioning of the screen and secondary tensioning of the screen
