Embodiment 1

[0041] Such as Figures 1 to 4 As shown, the main part of the vibrating screen includes an upper screen frame 1, a lower screen frame 2, a screen mesh, a press ring and a tension ring. The tension ring is arranged below the screen cloth, and the pressure net ring is fixedly arranged at the bottom of the upper screen frame 1 . The connection between the upper and lower screen frames is provided with a flange structure, and the specific connection method is that the lower end of the upper screen frame 1 is provided with a first flange, and the upper end of the lower screen frame 2 is provided with a second flange. The first flange is aligned with the second flange, and the edge portion of the screen is clamped by the first flange and the second flange. The inner diameter of the upper screen frame 1 is smaller than that of the lower screen frame 2, so when the first flange and the second flange are aligned, the first flange must protrude a part inward to form an annular boss str...

Embodiment 2

[0050] Compared with Embodiment 1, the clamping mechanism in this embodiment can adopt the following scheme:

[0051] Such as Figures 5 to 11As shown, the jacking mechanism includes a pedestal 5.1, a tension bolt 5.2 and a C-shaped hook body 5.3; a notch is opened on the lower screen frame 1, the pedestal 5.1 is fixed on the outer wall of the upper screen frame 1, and the tension bolt 5.2 is vertically arranged on the On the pedestal 5.1, the lower end is processed with external threads; the upper end of the C-shaped hook body 5.3 has a threaded hole and is connected with the tension bolt 5.2 through a thread pair, and the lower end of the C-shaped hook body 5.3 passes through the notch and the tension ring 10 connect.

[0052] Although there is no direct fixed relationship between the tension bolt 5.2 and the pedestal 5.1, since the tension ring 10 can contact the screen 3 and be tightened by pressure, and three tightening mechanisms are provided at the same time, the tight...

Abstract

The invention discloses a method for rapidly tightening a screen mesh, and a vibrating screen. The vibrating screen comprises a screen frame and a screen mesh, and is characterized in that a tensioning ring is arranged below the screen mesh; when the screen mesh is loose, the tensioning ring is enabled to move upwards to further tighten the loose screen mesh by pushing so that the screen mesh is tightened. The method and the vibrating screen disclosed by the invention have the beneficial effects that a mesh pressing ring is fixedly arranged at the lower part of an upper screen frame, the edge part of the screen mesh is bent downwards and then bent upwards around the mesh pressing ring so that the screen mesh is further tightened; the screen mesh is unlikely to loosen after the edge of the screen mesh is bent twice reversely. Due to the arrangement of the tensioning ring which is arranged below the screen mesh and connected with a jacking mechanism, a hand wheel can be rotated to drive the tensioning ring to move upwards so as to jack the screen mesh so that the screen mesh can be tightened; the screen mesh can be continuously tightened without shutdown by just rotating the hand wheel.

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 press ring first an...
