Sieve screen tightening machine

Abstract

The invention relates to a sieve screen tightening machine, which comprises a machine frame, a plurality of tightening mechanisms, a hand wheel and a switch, wherein a supporting plate is arranged in the middle of the top of the machine frame; the tightening mechanisms are symmetrically arranged on the supporting plate on the machine frame in the transverse and longitudinal directions; each tightening mechanism comprises a handle, a hinge mechanism, a pressure plate, a mounting seat and an air cylinder; the pressure plates include upper pressure plates and lower pressure plates, which are connected up and down in a symmetric manner; the air cylinders are arranged in air cylinder fixing holders; the piston rod of each air cylinder is connected with a fixed block; a mounting seat with a stepped face is arranged in each air cylinder fixing seat; the lower pressure plates are clamped at the positions of the stepped faces of the mounting seats and are pressed on the fixed blocks; the mounting seats are provided with the hinge mechanisms; the hinge mechanisms are connected to the upper pressure plates by connecting rods which are extended out; and the tops of the hinge mechanisms are connected with operating handles. The sieve screen tightening machine improves the production efficiency and service life of the sieve screen.

Description

technical field [0001] The invention relates to the field of mechanical processing, especially a screen tensioner. Background technique [0002] Screens are widely used in printing, electronics, mining, pharmaceuticals, grain, food processing, chemical and other fields. The metal mesh is commonly used, and the metal mesh has four main functions: (1) used for screening of solid particles and powder; (2) filtered, used for filtering and purifying liquid or gas; (3) used as a protective mesh machine Protection equipment; (4) Used in construction industry, highway, bridge and skeleton support, etc. Usually, the production of the screen needs to meet the smooth and neat surface, firm and uniform structure, good overall performance, and no loosening will occur even if it is partially loaded or subjected to a large pressure during use. [0003] At present, most of the existing screen tensioning machines in our country use manual type for stretching and adhesion. Due to manual ope...
