Description
Technical Field
The utility model belongs to the field of vibrating screen machinery, mainly be the screen cloth overspeed device tensioner who relates to installation flexible screen cloth or weave the screen cloth.
Background
The tension device of the screen cloth of the vibrating screen is an installation mode for installing a flexible screen cloth or a woven screen cloth, and the screen cloth is installed on a screen frame through a connecting piece and a tension mechanism. The installation and adjustment is difficult because the screen cloth tensioning device needs to be installed on the screen frame or the screen frame cross beam. The screen tensioning device is also inconvenient in replacing and adjusting the screen inside the screen box. If the adjustment components of the screen tensioning device are subject to wear from the material flow, which affects the removal of the components, adjustment and replacement is more difficult. In order to reduce the damage of the screen and the screen tensioning device in the using process, effectively improve the screening efficiency and facilitate the maintenance work, the tensioning device of the screen of the existing vibrating screen needs to be improved.
Disclosure of Invention
The utility model aims at providing a screen cloth overspeed device tensioner, its straining device sets up in the outside of reel curb plate, is favorable to the adjustment and the maintenance of screen cloth to be changed.
The utility model discloses a realize through following technical scheme, including reel, screen cloth and straining device, characterized by: the two tensioning fixing seats are arranged outside the two side plates of the screen frame, and the threaded ends of the two fastening blocks respectively penetrate through round holes in the tensioning fixing seats and are fixed through locking nuts with grooves; two ends of the tensioning plate respectively penetrate through the preformed holes on the two side plates of the screen frame and are inserted into the holes of the fastening blocks positioned outside the side plates of the screen frame; one end of the screen mesh is hooked on the cross beam of the screen frame, and the other end of the screen mesh is hooked on the tensioning plate.
The locking nut of the fixed fastening block is a locking nut with a groove, and a gasket is arranged between the locking nut and the tensioning fixed seat. Two side faces of the tensioning fixing seat are provided with jackscrews, and the corresponding positions of the side faces of the fastening block are provided with positioning holes. The screen surface of shale shaker comprises 2 ~ 5 sections screen cloth, is provided with 1 ~ 3 screen cloth supporting beam below every section screen cloth.
The beneficial effects of the utility model are that, tensioning fixing base and fastening block are located the outside of reel curb plate, rotate lock nut, make two fastening blocks drive the tensioning plate screen cloth tensioning. After the screen cloth is tensioned, the locking nut is locked, and the jackscrew is screwed into the positioning hole, so that the fastening block is fixed. Can be operated outside the screen box, and is convenient and fast. The vibrating screen has the characteristics of simple and compact structure, good performance, safety, reliability and simplicity in disassembly, and can be applied to various vibrating screens in the industries of metallurgy, mines, coal and the like for installing flexible screens and weaving screens.
