Abstract

The invention provides an improved pneumatic stop structure. By utilizing the improved pneumatic stop structure, back materials in a roller way can be stopped being conveyed forward under the condition that a material feeder is not stopped, so that front materials can be conveyed successfully, and simultaneously the material feeder cannot be abraded. The improved pneumatic stop structure comprises a bracket and a roller way conveying plane, and is characterized in that a baffle plate is arranged between adjacent rollers; the tail end of the bottom of each baffle plate is sleeved at one end of a revolving shaft; the other end of the revolving shaft is sleeved on a base plate; the base plate is fixedly connected with the bracket; the middle end of the bottom of each baffle plate is connected with one end of a connecting block through a rotating shaft; the other end of the connecting block is connected with a piston rod of an air cylinder through one end of a rotary shaft; the other end of the rotary shaft is positioned in the linear slot of the base plate; and an air cylinder seat of the air cylinder is fixedly connected with the bracket.

Description

The pneumatic barrier structure of improved type

Technical field

The present invention relates to the technical field of conveyor construction, be specially the pneumatic barrier structure of improved type.

Background technology

Existing conveyer is in the process of convey materials; Need the rear portion material be stopped for a moment a little through regular meeting's appearance; Guarantee fwd mass transport situation smoothly, the existing structure common practice is to stop feed, though can guarantee that like this fwd material is smooth and easy; But the wearing and tearing meeting for feeding machine is very big, because can directly produce wearing and tearing to body in the process that feeding machine stops, opening.

Summary of the invention

To the problems referred to above, the invention provides the pneumatic barrier structure of improved type, it makes that under the non-stop-machine situation of feeding machine, the back material of roller-way can stop to be fed forward, and guarantees that the fwd mass transport simultaneously smoothly, does not produce wearing and tearing to feeding machine.

The pneumatic barrier structure of improved type; Its technical scheme is such: it comprises support, roller-way transporting flat, it is characterized in that: be provided with baffle plate in the middle of the said adjacent running roller, the bottom tail end of said baffle plate is set in axis of revolution one end; The other end of said axis of revolution is set in substrate; Said substrate is fastenedly connected said support, and the bottom middle-end of said baffle plate is through an end of rotating shaft connection contiguous block, and the other end of said contiguous block connects the piston rod of cylinder through S. A. one end; The said S. A. other end is positioned at the straight-line groove of substrate, and the cylinder block of said cylinder is fastenedly connected said support.

It is further characterized in that: the direction of action of said cylinder is parallel to the roller-way transporting flat, and the direction of action of said straight-line groove and said cylinder is on same straight line.

After adopting said structure of the present invention, under the normal feeding state, the top of baffle plate is lower than the roller-way transporting flat, when fwd material generation feeding has some setbacks; The feed of feeding machine is turned down, and this moment, the cylinder action makes S. A. advance along straight-line groove; Contiguous block erects gradually, and the top of final baffle plate is higher than the roller-way transporting flat, with the back material of short duration be barred from the baffle plate place; After treating that the fwd mass transport is smooth and easy, actuating cylinder at once is reduced to original position with the top of baffle plate; The feed amount of feeding machine is replied, guarantee that normal feeding proceeds, it makes under the non-stop-machine situation of feeding machine; The back material of roller-way can stop to be fed forward, and guarantees that the fwd mass transport simultaneously smoothly, does not produce wearing and tearing to feeding machine.

Fig. 1 is the structural representation under the normal feeding state of the present invention;

Fig. 2 is the structural representation under the backgauge state of the present invention.

The specific embodiment

See Fig. 1, Fig. 2; It comprises support 1, roller-way transporting flat 2, is provided with baffle plate 3 in the middle of the adjacent running roller (do not draw among the figure and belong to existing mature structure), and bottom 4 tail ends of baffle plate 3 are set in axis of revolution 5 one ends; The other end of axis of revolution 5 is set in substrate 6; Substrate 6 is fastenedly connected support 1, and bottom 4 middle-ends of baffle plate 3 are through an end of rotating shaft 7 connection contiguous blocks 8, and the other end of contiguous block 8 connects the piston rod of cylinder 10 through S. A. 9 one ends; S. A. 9 other ends are positioned at the straight-line groove 11 of substrate 6, and the cylinder block of cylinder 10 is fastenedly connected support 1.The direction of action of cylinder 10 is parallel to roller-way transporting flat 2, and the direction of action of straight-line groove 11 and cylinder 10 is on same straight line.Among Fig. 1,12 is the formed elevation plane in top of normal feed status lower baffle plate 3; Among Fig. 2,13 is the formed elevation plane in top of backgauge state lower baffle plate 3; Among Fig. 1, Fig. 2,14 is goods.
