A screen with a tensioning mechanism

Abstract

The invention discloses a screen cloth with a tensioning mechanism, which comprises a frame, a screen cloth is arranged in the middle of the frame, and a first arc-shaped slide bar is provided through a slide rail under the frame, and the first arc-shaped slide bar Gear teeth are provided on the side, and a first gear is provided on the side of the frame, the first gear is power-connected to the first motor, the first gear is meshed with the first arc-shaped slider, and the first arc-shaped A first tensioning member is fixedly installed on the slide bar, the first tensioning member is connected with a first tensioning rope, a first rotating shaft is arranged on the inner side of the frame, and a first guide wheel is installed on the first rotating shaft , the inner side of the frame is also provided with a first fixed shaft, the first fixed shaft is arranged opposite to the first rotating shaft, and the first tensioning rope is fixed to the first fixed shaft via the first guide wheel connect. Reduce the force on the screen and slow down the occurrence of screen relaxation.

Description

technical field [0001] The invention relates to the technical field of screens, in particular to a screen with a tensioning mechanism. Background technique [0002] The sieve is a commonly used screening tool in the industry, which is used to sieve particles of different sizes. At the same time, the sieve also has a filtering function, making it a common tool in life and industry. [0003] Common sieves are composed of frames and wires, and meshes are formed between the wires. The meshes of the screens have very high requirements, and materials of different volumes can be screened according to the size of different meshes. The sieve can classify and screen materials. [0004] But the applicant finds that the prior art at least has the following problems: [0005] When the sieve is sieving, its mesh wire will carry a large force of the material to be sieved. If things go on like this, the mesh wire of the sieve mesh will easily loosen, and the loose mesh wire will cause the...

Problems solved by technology

[0005] When the sieve is sieving, its mesh wire will carry a large force of the material to be sieved. If things go on like this, the mesh wire of the sieve mesh will easily loosen, and the loose mesh wire will cause the mesh to increase, and the material that meets the requirements cannot be screened.
