Abstract

The utility model relates to a screw feeder, which comprises a screw conveyer and a hopper arranged on a feeding port of the screw conveyer. A material feeding port is arranged on the hopper, a stirring paddle driven by a motor is arranged inside the hopper, and a spindle of the stirring paddle is arranged horizontally. The screw feeder is characterized in that a material sensor is arranged in the middle of the hopper and is connected with the motor through a programmable controller. The screw feeder has the advantage that when an overhead phenomenon happens in the hopper and after materials stack in the hopper and are higher than the material sensor, the programmable controller controls the motor to start up according to an electrical signal of the material sensor, and then the stirring paddle stirs the materials in the hopper. Therefore, the phenomenon that the materials can not successfully enter the screw feeder is avoided, the motor is not needed to be on at all times, and energy consumption is reduced.

Description

A kind of screw feeder

Technical field

The utility model relates to a kind of screw feeder, particularly a kind of screw feeder that reduces energy resource consumption.

Background technology

Traditional screw feeder comprises auger loader, is located at the pyramid hopper on the auger loader inlet point, establishes the material inlet point on the hopper, after material enters auger loader by the material inlet point, is discharged from discharging opening by the blade promotion of auger loader.Granular material is prone to arch formation after entering feeder, causes material occurring in the hopper middle and lower part and makes somebody a mere figurehead, and can't enter auger loader and transport out, and influences the serialization ordinary production.At present general solution is the inspection by the workman, just utilizes instrument to knock hopper in case take place to build bridge, and makes it produce vibration, the elimination arch formation takes place, or the direct labor directly stirs the material of making somebody a mere figurehead, and labor strength is big, dust is more, and this occupational health health to the employee has caused injury.Occurred a kind of screw feeder that solves arch formation at present, be built-in with one by motor-driven paddle,, avoided arch formation by the material in the paddle stirring hopper by hopper.Whether its shortcoming is: no matter occur in the hopper building bridge, all work always, cause the waste of the energy.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of screw feeder that reduces energy resource consumption.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of screw feeder, comprise auger loader, be located at the hopper on the auger loader inlet point, establish the material inlet point on the hopper, described hopper is built-in with one by motor-driven paddle, and the rotating shaft of described paddle is horizontally disposed with; Its innovative point is: the middle part of described hopper is provided with a material sensor, and this material sensor is connected with motor by Programmable Logic Controller.

Advantage of the present utility model is: when occurring making somebody a mere figurehead phenomenon in the hopper, solid accumulation is in hopper and after being higher than the material sensor, Programmable Logic Controller is according to the electric signal control electric motor starting of material sensor, by the material in the paddle stirring hopper, avoid material to enter smoothly in the auger loader, motor need not to open always, has reduced the consumption of the energy.

Description of drawings

Fig. 1 is the utility model screw feeder structural representation.

The specific embodiment

As shown in drawings, comprise auger loader 1, hopper 2, material inlet point 3, paddle 4, motor 5, material sensor 6, Programmable Logic Controller 7.

The feeder hopper 2 of above-mentioned auger loader 1 is provided with hopper 2, establishes material inlet point 3 on the hopper 2.Paddle 4 is built in the hopper 2, and its rotating shaft is horizontally disposed with, and paddle 4 is driven by motor 5.The middle part of hopper 2 is provided with a material sensor 6, and this material sensor 6 is connected with motor by Programmable Logic Controller 7.

After occurring built on stilts phenomenon in the hopper 2, solid accumulation is more and more higher, is started by the electric signal control motor 5 of Programmable Logic Controller 7 according to material sensor 6, by the material that paddle 4 stirs in the hopper 2, avoids material to enter smoothly in the helical feed 1.Motor 5 need not long-time unlatching, has reduced energy resource consumption.

Claims

1. a screw feeder comprises auger loader, is located at the hopper on the auger loader inlet point, establishes the material inlet point on the hopper, and described hopper is built-in with one by motor-driven paddle, and the rotating shaft of described paddle is horizontally disposed with; It is characterized in that: the middle part of described hopper is provided with a material sensor, and this material sensor is connected with motor by Programmable Logic Controller.
