Abstract
The invention relates to a screen tensioning device for a vibrating sieve. The screen tensioning device is characterized in that a triangular bracket is welded outside a sieve frame; a support plate is welded inside the sieve frame; an included angle alpha is formed by a wide right-angle surface of the triangular bracket and an outer plane of the sieve frame; a first bolt hole is formed on the wide right-angle surface of the triangular bracket; an upper edge of a groove-shaped tensioning steel plate leans against the support plate; a lower edge of the groove-shaped tensioning steel plate leans against a screen hemming pulling plate; a square hole which is in sliding fit with a square neck of a bolt is formed at the bottom surface of the groove-shaped tensioning steel plate; the square hole, the first bolt hole and a second bolt hole of the sieve frame share one central line and are vertical to the wide right-angle surface of the triangular bracket; a step bolt is inserted into the square hole, the second bolt hole and the first bolt hole; and a double nut and a spherical washer are tightly engaged with the step bolt. The pulling force of the inclined step bolt can be decomposed into a horizontal pulling force for tensioning the screen and a component force for vertically downwards pressing the screen hemming pulling plate, so that the screen hemming pulling plate is prevented from shaking up and down on a bracket when the vibrating sieve vibrates.
Description
Technical field
The present invention relates to a kind of screening plant of material, particularly a kind of vibrating screen mesh take-up device.
Background technology
The screen frame of existing vibratory sieve and screen cloth tension all are to adopt tensioning plate to fasten the arm-tie on the both sides of screen cloth, strain tensioning plate with leveling screw then, thereby screen cloth is strained.This structure only has tightening force to screen cloth both sides horizontal direction owing to tensioning plate, and does not have active force in vertical direction, and the both sides of screen cloth can not be adjacent to the carriage on screen frame both sides well.Vibratory sieve when work, fastening because the screen cloth both sides do not have in vertical direction, so under the inertia force effect that the deadweight and the high frequency of compass screen surface material produces, screen cloth teetertotters easily, thereby the screen cloth absent-mindedness occurs, reduce the production capacity of vibratory sieve, also can quicken the breakage of screen cloth.
Summary of the invention
The purpose of this invention is to provide the vibrating screen mesh take-up device that a kind of screen cloth crimping arm-tie that prevents to be placed on above the carriage teetertotters.
Technical scheme of the present invention is: a kind of vibrating screen mesh take-up device comprises carriage that is welded on the screen frame inboard and the screen cloth crimping arm-tie that is placed on the carriage; Weld A-frame in the position that the screen frame outside is corresponding with carriage, be higher than the position welding support plate of carriage in the screen frame inboard; Angle α=10 of the outer side plane of the wide right angle face of A-frame and screen frame °-40 °, the wide right angle face of A-frame is provided with first bolt hole.The top that is positioned at the flute profile tensioning steel plate of screen frame inboard is pressed against on the support plate, and the bottom of flute profile tensioning steel plate is pressed against on the screen cloth crimping arm-tie, and flute profile tensioning steel plate bottom surface is parallel with the wide right angle face of A-frame; Flute profile tensioning steel plate bottom surface is provided with the square opening that the square neck with half-round head square neck bolt is slidingly matched, the screen frame place that is welded with A-frame is provided with second bolt hole, total same the center line of square opening, second bolt hole and first bolt hole and perpendicular to the wide right angle face of A-frame, the round bar of second bolt hole and first bolt hole and half-round head square neck bolt is slidingly matched; Half-round head square neck bolt penetrates from square opening, second bolt hole and first bolt hole of flute profile tensioning steel plate, and double nut and spheric washer are tightened from the A-frame outside and half-round head square neck bolt engagement.The preferred angle α of the outer side plane of the wide right angle face of described A-frame and screen frame=15 °-20 °.The angle on the center line of half-round head square neck bolt and vibrating screen mesh plane also is α.
The invention has the beneficial effects as follows: because the center line of half-round head square neck bolt and the angle on vibrating screen mesh plane are α, the pulling force of tilting half-round head square neck bolt can be decomposed into horizontal pull and component vertically downward.The horizontal tensioning vibrating screen mesh of horizontal pull, component vertically downward is pressed on screen cloth crimping arm-tie downwards on the carriage of screen frame inboard by flute profile tensioning steel plate, when preventing vibratory sieve work, screen cloth crimping arm-tie teetertotters on the carriage of screen frame inboard, thereby improved the production capacity of vibratory sieve, prolonged the service life of screen cloth.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Embodiment is as shown in Figure 1: a kind of vibrating screen mesh take-up device comprises the carriage 2 that is welded on screen frame 3 inboards and is placed on screen cloth crimping arm-tie 7 on the carriage 2.At the corresponding position welding A-frame 1 of screen frame 3 outsides and carriage 2, be higher than the position welding support plate 4 of carriage 2 in screen frame 3 inboards.Angle α=15 of the wide right angle face of A-frame 1 and screen frame 3 outer side planes °-20 °, the wide right angle face of A-frame 1 is provided with first bolt hole; The top that is positioned at the flute profile tensioning steel plate 5 of screen frame 3 inboards is pressed against on the support plate 4, and the bottom of flute profile tensioning steel plate 5 is pressed against on the screen cloth crimping arm-tie 7, and flute profile tensioning steel plate 5 bottom surfaces are parallel with the wide right angle face of A-frame 1.Flute profile tensioning steel plate 5 bottom surfaces are provided with the square opening that the square neck with half-round head square neck bolt 6 is slidingly matched, screen frame 3 places that are welded with A-frame 1 are provided with second bolt hole, total same the center line of square opening, second bolt hole and first bolt hole and perpendicular to the wide right angle face of A-frame 1, the round bar of second bolt hole and first bolt hole and half-round head square neck bolt 6 is slidingly matched.Half-round head square neck bolt 6 penetrates from square opening, second bolt hole and first bolt hole of flute profile tensioning steel plate 5, and double nut and spheric washer are tightened from A-frame 1 outside and half-round head square neck bolt 6 engagements.Because angle α=15 on the center line of half-round head square neck bolt and vibrating screen mesh plane °-20 °, the pulling force of tilting half-round head square neck bolt can be decomposed into horizontal pull and component vertically downward.The horizontal tensioning vibrating screen mesh of horizontal pull, component vertically downward is pressed on screen cloth crimping arm-tie downwards on the carriage of screen frame inboard by flute profile tensioning steel plate, when preventing vibratory sieve work, screen cloth crimping arm-tie teetertotters on the carriage of screen frame inboard, thereby improved the production capacity of vibratory sieve, prolonged the service life of screen cloth.
