Description
Technical field
The utility model relates to the accurate meausring apparatus of the raw material of industry, particularly is used for the accurate drawing-in device of accurate weighing electronic scales.
Technical background
In glass industry and other similar industry, the raw material of industrial products generally is combined together according to a certain percentage in an orderly manner by various materials, the effective carrier platform that these raw materials are combined together in an orderly manner is exactly " a various materials automatic weighing system ", is commonly called as industrial electronic scale.When being arranged, the each weighing of several raw materials only needs 1～2 kilogram of weighing in these various materials, even still less, because the weighing range is little, so also just higher to its permissible accuracy.This has become the bottleneck in the industry batching, also is a core technology with high added value.At present in the world, famous professional weighing company of several families such as Japanese YAMATO, German EME and Finland RAUTE all produces keen interest to this core technology.Many high-end user merchants in the glass industry guarantee for the production to high quality glass, and are too impatient to wait especially to the demand of this core technology.At food service industry, chemical industry and other building material industry, the user merchant of the accurate weighing of the micro-journey of every needs holds suitable urgent attitude to this in addition.
The design of the accurate weighing electronic scales of micro-journey of main flow roughly is made up of accurate feeding serew batcher, accurate this two big key element of weighing mechanism in the world at present, and be aided with the annex of accurate weighing instrument and other multiple safeguard measure, making its weighing precision reach with 1 gram is a scale division value, even littler.Therefore, accomplish accurate weighing, must at first accomplish accurate feeding, but the not enough science of structure of existing screw feed device causes each feeding precision lower.Through extensively retrieval, still find no the technical scheme relevant with the utility model.
Summary of the invention
The purpose of this utility model is exactly a kind of accurate drawing-in device that designs in order to overcome the existing relatively poor defective of screw feed device feeding precision.
The utility model has adopted following technical scheme:
A kind of drawing-in device that is used for accurate weighing electronic scales, it is by feeding warehouse, screw-conveyer-shaft, feed pipe and power drive mechanism are formed, screw-conveyer-shaft is arranged in the feeding warehouse, and by the power drive mechanism driven rotary, feed pipe is connected on the feeding warehouse, the part that screw-conveyer-shaft is positioned at beyond the feeding warehouse cooperates with the feed pipe suit, it is characterized in that: the discharging end of feed pipe is provided with a support, connect a cylinder on the support, connect a stop gate that cooperates with feed pipe on the cylinder piston axle, also connect a guide rod on the support, be connected with spring between guide rod and support, the other end of guide rod links to each other with stop gate.Be provided with stirring apparatus in the feeding warehouse, stirring apparatus connects rotation by power drive mechanism.
The utility model adopts advanced in the world design and processing technology theory, and screw-conveyer-shaft adopts the single-point type support design in caliber, though the designing requirement height, difficulty of processing is big, can gentle stable and uniform ground convey materials in the time of really guaranteeing main shaft work.The material of main shaft and blade adopts advanced wear resistant corrosion resistant processing treatment process, special material for the various materials of tackling numerous and complicated, in the design of screw pitch, adopt and switch political loyalty apart from optimal design, special material at every kind of material, screw pitch is also different, and on the same screw spindle, the front and back pitch of its blade is also different.At the special material of the easy caking of some easily damp easily arch, the also supporting stirring apparatus that designed of the utility model is installed in feeding warehouse inside in addition.In order to guarantee the accuracy of material weighing, also designed the driving by cylinder and turn-off gate fast freely of going slick at the discharging opening place of feed pipe, its power is from the minitype cylinder of high-quality, it instructs from complicated and accurate careful calculating of control system self-control software, within the normal tolerance range that the momentum value of assurance material is limited in allowing.
Advantage of the present utility model is: pushing precision significantly improves, good stability, and the amount of feeding is carried out by the computer program control cylinder, and control is convenient, metering is accurate.
Description of drawings:
Fig. 1 is a front view of the present utility model.
Embodiment:
As shown in Figure 1, screw-conveyer-shaft 4 is installed in feeding warehouse 1 middle and lower part, the helical blade 5 that is provided with on the screw-conveyer-shaft 4 is the distances of switching political loyalty, the below of feeding warehouse 1 is provided with motor 12 and variator 12a thereof as actuating unit, connect sprocket wheel 13 on the output shaft of variator 12a, it is connected with two strands wheel 14 on being connected in screw-conveyer-shaft 4 by chain, double-strandedly takes turns 14 and is connected with sprocket wheel 15 on the shaft 2 by chain, and shaft 2 is provided with a pair of stirrer gear 3.Left side at feeding warehouse 1 connects a feed pipe 6, and the part that feeding warehouse is stretched out in screw-conveyer-shaft 4 left sides cooperates with feed pipe 6 suits, so that convey materials.Left part at feed pipe 6 connects a support 11, connect a cylinder 7 on the support 11, connect a stop gate 10 that cooperates with feed pipe 6 on the axis of the piston of cylinder alive 7, also connect a guide rod 8 on the support, 11 on guide rod 8 and support are connected with spring 9, and the other end of guide rod links to each other with stop gate 10.
The course of work of the present utility model is as follows: motor 12 drives screw-conveyer-shaft 4 and shaft 2 rotates simultaneously, the material that enters feeding warehouse 1 is along with screw-conveyer-shaft is fed forward the mouth of pipe of leading feed pipe 6 along feed pipe, after cylinder 7 obtains instruction, stretch out the axis of the piston stop gate 10 opens blink and cutting out rapidly, a certain amount of material flows out the feed pipe mouth of pipe in this blink, relevant between the time of the amount that material flows out and stop gate switching, it is accurately to be controlled by computer program, can be as accurate as 1 gram.
