Description

Spiral feeder

Technical Field

The utility model relates to a feeder especially relates to a screw feeder.

Background

Feeder, refers to a machine for transporting materials. The method is commonly used for the automatic, numerical control and precise conveying of materials such as granular materials, powder materials, flaky materials, strip materials and the like. The light industry and the heavy industry are indispensable transmission equipment. The screw feeder conveys the material by moving the material by a rotating screw blade, and the force by which the material does not rotate together with the screw feeder blade is the weight of the material itself and the frictional resistance of the screw feeder housing to the material.

Common screw feeder, because the discharging pipe is perpendicular with the screw drive axle, the material need turn to perpendicularly when carrying the discharging pipe through the screw drive axle, needs great extrusion force extrusion material to turn to perpendicularly this moment along the discharging pipe output, because the material extrusion with turn to, lead to the entrance of discharging pipe to block up easily, lead to material transmission efficiency lower.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art, the utility model provides a screw feeder.

The utility model provides a technical scheme that its technical problem adopted is:

the spiral feeder comprises a shell, a spiral driving shaft is arranged in the shell, one end of the spiral driving shaft penetrates through the shell and is connected with a speed reducer, the speed reducer is connected with a driving motor, a discharging pipe is arranged on the lower side of the shell, an air suction pipe is arranged at an inlet in the discharging pipe and perpendicularly penetrates through the discharging pipe after the air suction pipe is bent, the flange end of the air suction pipe outside the discharging pipe is connected with the flange end of a single-flange short pipe through a bolt, and the other end of the single-flange short pipe is connected with.

In a preferred embodiment of the screw feeder, the upper side of the housing is provided with an inlet pipe at one end close to the driving motor, and the top end of the inlet pipe is connected with a conical funnel.

In a preferred embodiment of the screw feeder, the inlet end of the air suction pipe is provided with a first groove, a coarse filter net is arranged in the first groove, and the coarse filter net is fixed through a snap ring.

In a preferred embodiment of the screw feeder, the flange end of the air suction pipe is provided with a second groove, the flange end of the single flange short pipe is provided with a third groove opposite to the second groove, and after the air suction pipe and the single flange short pipe pass through the bolt connection, the second groove and the third groove form an annular cavity.

In a preferred embodiment of the screw feeder of the present invention, the annular cavity further contains a fine filter screen.

Compared with the prior art, the utility model provides a spiral feeder's beneficial effect:

one, one side of discharging pipe sets up the air exhauster, breathes in through the air exhauster, can make the pan feeding mouth department of discharging pipe form the negative pressure, does benefit to the material and removes to the discharging pipe fast, does benefit to and improves material conveying efficiency, because the suction effect of air exhauster, can reduce the extrusion force that the material need when turning to, does benefit to and reduces discharging pipe entrance and blocks up.

And secondly, a coarse filter screen and a fine filter screen are arranged at the air suction end of the exhaust fan, and materials can be prevented from being sucked into the exhaust fan through double-layer filtering.
