Balance weight on measure lever in convenient for increases the accuracy of weight and constancy, at the scale frame fixed balance weight and imperceptible balance weight (link chains) devices are equipped, to heighten or lower one end of the link chains can realize differential tuning balance weight, the operation is simple; tensioning system of conveying machine effectively reduces roller's shake and play that in process of operation; combined type sweeper, as well as cleans the roller, but also cleans the adhesive tape, whose advantages are firstly, overhead scale frame body accepts the function of perpendicular force, effectively increases the measuring accuracy; secondly, the quality of matching products is widely improved; thirdly, in convenient for realizing automation control and work situation and strength's improvement.

Description

Trace dynamic measurement, matching device

Technical field

The utility model relates to a kind of dynamic metering device, particularly a kind of micro-dynamic measurement, matching device.

Background technology

At present, the dynamic measurement dosing device of domestic production, generally be greatly, measure under the middle flow, on dynamic measurement, in the three elements of lever, fulcrum is particularly important, employed fulcrum in the existing dynamic metering device, as: the supporting of rubber gudgeon, the knife cutter holds fulcrum, the shackle fulcrum, X reed structure etc., above-mentioned fulcrum is applicable to greatly, the metering of middle flow, under the low discharge situation, low discharge promptly generally is several kilograms/hours continuous flows meterings below-100 kilograms/hour, its measuring accuracy does not reach the requirement of regulation, and can not be applied in the low discharge metering.The method that generally adopts in existing production technology is after claiming with balance or electronic platform scale, to pour in the container and stir, or take the volumetric metering method, and operation is discontinuous, belongs to the measuring apparatus of discontinuous form, the operation of slow, the difficult realization robotization of rhythm of production continuous measurement.

Summary of the invention

The purpose of this utility model is will provide a kind of can satisfy micro-dynamic measurement, the matching device that the small flowmeter accuracy of measurement requires.Particularly to as: pigment, catalyzer, adjuvant etc. carry out dynamic continuous measure, to realize higher product quality and to improve automatization level.

The purpose of this utility model is achieved in that this device is made up of scale body, velometer, conveyor, several parts of control instrument, scale body, velometer are installed on the conveyor, the scale body is installed in the middle part of conveyor, and velometer is installed in an end of conveyor, and control instrument is installed in the pulpit.

Conveyor comprises drive roll, driven cylinder, carrying roller, adhesive tape, swabbing pig and frame, drive roll and driven cylinder are positioned at two ends of frame, adhesive tape is centered around on drive roll and the driven cylinder external diameter, carrying roller is installed on the frame, between drive roll and driven cylinder, swabbing pig is installed in frame, is close on drive roll and the driven cylinder.

The scale body comprises fulcrum, LOAD CELLS, oscillating bearing, scale frame and counterweight, the scale frame is installed on the frame of conveyer, LOAD CELLS, oscillating bearing is installed in the position, force of scale frame, LOAD CELLS links to each other with frame by sensor support base, the fulcrum of scale body is a single reed structure, the vertical placement, one end links to each other with frame, the other end links to each other with the scale frame, counterweight comprises fixed weight and fine setting counterweight, counterweight is the opposite side that the center is installed in the scale frame with the fulcrum, and fixed weight is installed on the scale frame, and the fine setting counterweight links to each other with fixed weight, the support of fine setting counterweight is fixed on the frame, is connected with chain between the support of fine setting counterweight and the fixed weight.

Velometer has a housing, is connected with magneto or scrambler in the housing, and the axle of magneto or scrambler is connected with the driven drum shaft of conveyor.

Beneficial effect: owing to adopt such scheme, counterweight helps the raising of weighing precision on measuring lever, and can increase stability again, on this scale frame, fixed weight is arranged not only, and finely tune counterweight (chain) in addition and install, improve or reduction chain one end, can realize finely tuning counterweight, operation is simple; Lead in the front and back that are added with on bearing seat of the tension adjustment system of conveyor, add rail-guided, three kinds spacing, the same conventional func that realizes, can be implemented in the displacement or the undesirable state that produce in the whole course of action and reduce greatly, effectively reduce shake or the play of cylinder in the whole service process; Owing to adopted the combined type swabbing pig, not only purging roller but also clean adhesive tape.The fulcrum of scale body is a single reed structure and adopts the vertical placement of anti-convention to fix, and the sensitivity of scale body is improved, and low discharge continuous measurement precision is achieved, and has reached the purpose of this utility model.Its advantage have following some: 1, bigger improvement is arranged,, effectively improves measuring accuracy because the scale body is subjected to vertical force with the common main position of dynamic continuous measure equipment; 2, can improve the quality of proportioning product greatly; 3, help to realize the improvement of robotization control and work situation, intensity.
