Abstract
The utility model discloses a variable-pitch screw feeder comprising a housing, a feed inlet and a discharging outlet. The feed inlet and the discharging outlet are disposed on the housing and located at the two axial ends of the housing, a screw drive shaft is disposed inside the housing, the screw drive shaft is coaxially connected to a power drive device, a plurality of screw blades are disposed on the screw drive shaft, the screw blades are arranged on the screw drive shaft in a manner that the pitches of adjacent screw blades increase gradually from the feed inlet to the discharging outlet, and a stress sensor is disposed in the screw drive shaft. The variable-pitch screw feeder prevents occurrence of obstruction and guarantees smooth conveying of materials.
Description
Technical field
The utility model belongs to auger loader, is specifically related to a kind of variable-pitch auger feeder.
Background technology
Screw feeder is the conveying of collection powder material current stabilization, Weighing and the new generation product that quantitatively is controlled to be one, screw feeder is undertaken sense weight to the material of process by the crane span structure of weighing, to determine the weight of material on the adhesive tape, rear-mounted Digital Speed Testing sensor, the running velocity of continuous gauging feeder, the pulse output of this speed sensor is proportional to the speed of feeder, speed signal and weight signal are sent into the feeder controller together, microprocessor in the controller is handled, and produces and demonstration cumulative amount/instant flow rate.This flow compares with setting flow, and the actuating speed by control instrument output signal control frequency converter change feeder changes the mass flow on the feeder, approaches and remains on the feed flow that sets, thereby realize the requirement of dosing.
When the airtight charging and discharging of needs, usually adopt the variable-pitch auger feeder, under this usage condition, be by full helical feed principle work, because of pitch on throughput direction from large to small, cause materials flow not smooth, feeder obstruction and can not working.
The utility model content
The technical problems to be solved in the utility model provides a kind of materials flow variable-pitch auger feeder unobstructed, that can not stop up.
In order to solve the problems of the technologies described above, the utility model provides a kind of variable-pitch auger feeder, comprise casing, inlet point and discharging opening, inlet point and discharging opening are located on the casing and are positioned at the axial two ends of casing, described casing inside is provided with the screw drives axle, the screw drives axle is connected with Power Drive Unit is coaxial, and described screw drives axle is provided with the plural pieces helicallobe, and the direction of the spacing of adjacent helicallobe along inlet point to discharging opening increases setting gradually on the screw drives axle.
Because feeder is the full spiral principle of work that adopts, when material enters adjacent helicallobe in the casing from inlet point between, because the increase along with the pitch between adjacent helicallobe, can not be full of between adjacent helicallobe at the material near discharging opening, make material can be successfully discharge from discharging opening, make that whole materials flow is unobstructed and latch up phenomenon can not occur.
As the further restriction of technical solutions of the utility model, for the stressing conditions of screw drives axle is monitored in real time, be provided with strain gauge in the described screw drives axle.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment: as shown in Figure 1, the utility model provides a kind of variable-pitch auger feeder, comprise casing 2, inlet point 1 and discharging opening 5, inlet point 1 and discharging opening 5 are located on the casing 2 and are positioned at the axial two ends of casing 2, described casing 2 inside are provided with screw drives axle 3, screw drives axle 3 and 6 coaxial connections of Power Drive Unit, Power Drive Unit 6 comprises motor, engine petrol, diesel motor etc., can select according to the different operating demand; Described screw drives axle 3 is provided with plural pieces helicallobe 4,5 direction increases on screw drives axle 3 and arranges the spacing of adjacent helicallobe 4 gradually along inlet point 1 to discharging opening, be provided with connecting element between helicallobe 4 and the screw drives axle 3, make screw drives axle 3, connecting element and helicallobe 4 form the stability that three-legged structure increases helicallobe 4.
Material enters in the casing 2 from inlet point 1, work along with Power Drive Unit 6, material is full pitch conveying at inlet point 1 place, along with the rotation of helicallobe and the increase of helicallobe pitch, material at discharging opening 5 is not full of a pitch, thereby the situation of having avoided stopping up takes place, and makes that whole feeder mass transport is unobstructed.
Above-described only is preferred implementation of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that the utility model is implemented.
Claims (2)
1. variable-pitch auger feeder, comprise casing, inlet point and discharging opening, inlet point and discharging opening are located on the casing and are positioned at the axial two ends of casing, described casing inside is provided with the screw drives axle, the screw drives axle is connected with Power Drive Unit is coaxial, it is characterized in that: described screw drives axle is provided with the plural pieces helicallobe, and the direction of the spacing of adjacent helicallobe along inlet point to discharging opening increases setting gradually on the screw drives axle; Be provided with strain gauge in the described screw drives axle.
2. variable-pitch auger feeder according to claim 1 is characterized in that: be provided with connecting element between described helicallobe and the screw drives axle.
