Abstract
A kind of precision spin feedway, comprise the first conveyor screw, the first helical feed drive end unit is provided with discharge duct, is also provided with the second conveyor screw, first conveyor screw is connected with the second conveyor screw by the second discharging opening, and the discharge end of the second conveyor screw is connected with discharge duct; The internal diameter of delivery hose of the second described conveyor screw is less than the internal diameter of delivery hose of the first conveyor screw.In the second described conveyor screw, variable-frequency motor is connected with screw shaft by speed-changing mechanism.Second conveyor screw of the utility model by arranging, in mass transport close to when weighing target, the first conveyor screw that diameter is larger can be stopped, changing with the second less conveyor screw feeding of diameter, thus improve feed precision, ensure accuracy when weighing.Second conveyor screw adopts the scheme of variable-frequency motor, by progressively reducing minor spiral rotating speed, by controlling the speed of charging rate, can improve accuracy when weighing further, improve work efficiency.
Description
Technical field
The utility model relates to batching load transfer device field, particularly a kind of precision spin feedway for producing accurate feeding to ultra-thin glass.
Background technology
The feed proportioning system of current ultra-thin glass manufacturing enterprise, in use screw feeder feeding weighing process, when weighing, accuracy requirement is higher, and often the feed precision of out of reach process requirements, often appears off-gage phenomenon when feeding, in the feeding of tens grams or several grams.This phenomenon occurs mainly due to single tube spiral feeder screwed pipe comparatively large, is difficult to control.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of precision spin feedway, can accurately control feed precision, decrease error, improve work efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of precision spin feedway, comprise the first conveyor screw, first helical feed drive end unit is provided with discharge duct, also be provided with the second conveyor screw, first conveyor screw is connected with the second conveyor screw by the second discharging opening, and the discharge end of the second conveyor screw is connected with discharge duct;
The internal diameter of delivery hose of the second described conveyor screw is less than the internal diameter of delivery hose of the first conveyor screw.
Also discharge valve is provided with in the bottom of discharge duct.
In the second described conveyor screw, variable-frequency motor is connected with screw shaft by speed-changing mechanism.
Also clean-up port is provided with in the bottom of the second discharging opening.
A kind of precision spin feedway that the utility model provides, by the second conveyor screw arranged, can in mass transport close to when weighing target, stop the first conveyor screw that diameter is larger, change with the second less conveyor screw feeding of diameter, thus improve feed precision, ensure accuracy when weighing.In the scheme of further optimization, adopt the scheme of variable-frequency motor at the second conveyor screw, by progressively reducing minor spiral rotating speed, by controlling the speed of charging rate, accuracy when weighing can be improved further, improve work efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is integral structure schematic diagram of the present utility model.
In figure: the first conveyor screw 1, discharge duct 2, discharge valve 3, variable-frequency motor 4, speed-changing mechanism 5, screw shaft 6, the second discharging opening 7, clean-up port 8, the second conveyor screw 9.
Detailed description of the invention
As in Fig. 1, a kind of precision spin feedway, comprise the first conveyor screw 1, first conveyor screw 1 afterbody is provided with discharge duct 2, also be provided with the second conveyor screw 9, first conveyor screw 1 is connected with the second conveyor screw 9 by the second discharging opening 7, and the discharge end of the second conveyor screw 9 is connected with discharge duct 2;
The internal diameter of delivery hose of the second described conveyor screw 9 is less than the internal diameter of delivery hose of the first conveyor screw 1.Structure thus, when feed is close to when weighing target, namely stops the first conveyor screw 1, continues convey materials until reach weighing target, thus ensure that the object of accurate weighing with the second conveyor screw 9 that diameter is less.
In preferred scheme, in the second described conveyor screw 9, variable-frequency motor 4 is connected with screw shaft 6 by speed-changing mechanism 5.Structure thus, by controlling the rotating speed of the second conveyor screw 9, progressively reduces the rotating speed of the second conveyor screw 9, and then accurately controls the feeding speed of the second conveyor screw 9 further, improves accuracy when weighing, improves work efficiency.
Also be provided with discharge valve 3 in the bottom of discharge duct 2, the discharge valve of setting also can be assisted and be controlled to weigh accuracy.Clean-up port 8 is also provided with in the bottom of the second discharging opening 7.The feed end of the first conveyor screw 1 and discharge end are also provided with the clean-up port for clearing up.So that clean screw shaft.
