Summary of the invention
The purpose of this utility model is, a kind of belt tearing device that prevents is provided, and makes it in time find the accident of tearing in the operation process of belt, thereby cuts off the electricity supply, and belt feeder is shut down, and prevents that industrial accident from taking place.
The utility model for achieving the above object, be achieved through the following technical solutions: prevent the belt tearing device, comprise fixed mount, first rotating shaft and second rotating shaft are installed respectively on the fixed mount, first rotating shaft is connected with first rocking lever, second rotating shaft is connected with second rocking lever, first connecting rod is installed on the first rocking lever top, first connecting rod is connected with the first retaining roller, second connecting rod is installed on the second rocking lever top, second connecting rod is connected with the second retaining roller, between first rocking lever and second rocking lever back-moving spring is installed, bar is transmitted in hinge first displacement of first rocking lever upper end, and first displacement is transmitted the stroke beginning is installed on the bar, bar is transmitted in hinge second displacement of second rocking lever upper end, and second displacement is transmitted the displacement block is installed on the bar.Between the first retaining roller and the first connecting rod inclination angle is arranged vertically, between the second retaining roller and the second connecting rod inclination angle is arranged vertically.First displacement is transmitted on the bar first locating piece and second locating piece is installed respectively, and second displacement is transmitted on the bar the 3rd locating piece and the 4th locating piece are installed respectively.Mounting plate on the bar is transmitted in first displacement.Mounting plate on the bar is transmitted in second displacement.First strut bar is installed on the first connecting rod, and first strut bar is connected with the first retaining roller, and second strut bar is installed on the second connecting rod, and second strut bar is connected with the second retaining roller.
The utility model has the advantages that: it can import electrical apparatus control system by each parts with signal according to the change width of belt, cut off the belt feeder power supply, belt feeder is shut down, each structure running is flexibly reliable, signal transmits the accuracy height, thereby can avoid the generation of many industrial accidents.
Description of drawings
Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is plan structure scheme drawings of accompanying drawing 1; Accompanying drawing 3 is left TV structure scheme drawings of accompanying drawing 1.
The specific embodiment
7 is fixed mounts among the figure, first rotating shaft 6 and second rotating shaft 15 are installed respectively on the fixed mount 7, first rotating shaft 6 is connected with first rocking lever 5, second rotating shaft 15 is connected with second rocking lever 14, first connecting rod 1 is installed on first rocking lever, 5 tops, first connecting rod 1 is connected with the first retaining roller 2, second connecting rod 12 is installed on second rocking lever, 14 tops, second connecting rod 12 is connected with the second retaining roller 11, back-moving spring 13 is installed between first rocking lever 5 and second rocking lever 14, bar 3 is transmitted in first displacement of first rocking lever, 5 upper end hinges, first displacement is transmitted stroke beginning 4 is installed on the bar 3, second displacement of second rocking lever, 14 upper end hinges is transmitted bar 10, the second displacements and is transmitted installation displacement block 9 on the bar 10.In order better to make the retaining roller vertical with the belt edge, between the first retaining roller 2 and first connecting rod 12, an inclination angle is set vertically, between the second retaining roller 11 and the second connecting rod 12 inclination angle is set vertically.In order further to guarantee two displacements transmission bar parallel displacement, first displacement is transmitted to install respectively on the bar 3 on first locating piece 8 and second locating piece, 16, the second displacements transmission bar 10 the 3rd locating piece 18 and the 4th locating piece 17 is installed respectively.Mounting plate 19 on the bar 3 is transmitted in first displacement.Mounting plate 19 on the bar 10 is transmitted in second displacement.Further program of the utility model is: first strut bar 20 is installed on the first connecting rod 1, first strut bar 20 is connected with the first retaining roller 2, second strut bar 21 is installed on the second connecting rod 12, second strut bar 21 is connected with the second retaining roller 11, be convenient to make the retaining roller better vertical, make the signal transmission more accurate with the belt edge.The installation site of travel switch 4 described in the utility model and displacement block 9 can exchange.All can in the optional position that is installed in the belt feeder framework during the utility model use, the first retaining roller 2 and the second retaining roller 11 are arranged length direction two edges at belt, make the belt edge perpendicular to two retaining rollers, accurate to guarantee the signal transmission, travel switch 4 is connected with control system.When tearing appears in operation process in belt, belt is narrowed down or when broadening when loading material (belt narrows down when unloaded, then broaden), two retaining rollers drive two rocker-arm links and produce displacement under the effect of spring force, and then drive first displacement and transmit bar 3 and second displacement and transmit bar 10 and do opposing parallel and move, travel switch 4 passes to control system cut-out belt feeder power supply with signal after touching displacement block 9, belt feeder is shut down, thereby avoided the generation of industrial accident.
