Abstract
A dynamic weighing rack with shock absorption device is featured as setting the weighing transducer between bearing body and rack seat; setting elastic support plate and damper between bearing body and quantitative scale pan or between belt conveyor and rack; regulating and setting the bearing body mass, damping ratio of damper, elastic coefficient of elastic support plate according to principle of counter resonance and shock absorbing to make impact force generated by adding material in feeder and vibration force generated by motor or belt conveyor be minimum for meeting accuracy requirement of weighing .
Description
Technical field
The present invention is a kind of band vibration absorber dynamic weighing rack, relates to the packing technique field in the communications and transportation branch of operation Department of Transportation, and it is mainly used in the Dynamic Weighting of various quantitative processes of powder shape solid material and material conveying process.
Background technology
General weighing rack (device) is directly by weighing sensor support bearing body, and damper that spring that rigidity was also strong when weighing sensor can be reduced to elasticity coefficient k than Datong District and ratio of damping c are less and supporting body and material (quality m) are formed second-order system.According to kinetic theory analysis, damping ratio
Undamped natural frequency of a mechanical system
Second-order system o'clock is an optimum damping ratio in ξ=0.707, and the system responses performance is stable, fast, accurately.Because m is subjected to the limit of range of weighing, k and c are subjected to the restriction of weighing sensor structure and material, make that usually ξ is very little, and the system responses performance is poor.In the Dynamic Weighting of quantitative process of powder shape solid material or material conveying process, the weighing supporting body is subjected to reinforced impact of material or conveying motor oscillating etc. and causes various exciting force effects, be subjected to various frequency interferences influences simultaneously, make stand sensor displacement deformation amount generation sustained oscillation, shock range is big, stabilization time is long, is difficult within a short period of time obtain accurate weight signal, thereby influences weighing rapidity and accuracy.
In existing patented technology and Related product, as patent 98222470.2, a kind of sinking support of meausring apparatus, by between supporting body and fixed support, being provided with travel(l)ing rest, between travel(l)ing rest and fixed support, be provided with corresponding flexible board up and down, between supporting body and fixed support, be provided with LOAD CELLS, improve sensor response rapidity and accuracy.But, reduce the weighing accuracy owing at the sensor support supporting body simultaneously,, influence quality of material and sensor deflection linear relationship on the weighing sensor again by travel(l)ing rest and flexible board support bearing body.And for example the at a high speed full-automatic powder of the JL500B filling machine of weighing by external damper, increases damping ratio c and ratio of damping ξ, improves sensor response rapidity and accuracy.Because external damper while and fixed support, supporting body connect, equally also therefore the support bearing body also has certain influence to the weighing accuracy.
Patent 200420041213.0, a kind of weighing device of electronic scales is used for the weighing device of filled capsules.It adopts two parallel girder normal stress structure LOAD CELLS, and an end is fixedly attached on the steel structure support, and an end is fixedly attached on the beam of weighing, and is fixedly attached on the carrier by four cushion pads on the beam of weighing.Because cushion pad is all limited to the elasticity coefficient k and the damping ratio c raising of device, therefore in Dynamic Weighting, can not guarantee the carrier fast and stable fully, can not satisfy the requirement quick and precisely of Dynamic Weighting.
At present, in some document, mention by using antiresonance principle vibration damping or vibration isolation technique,, study large-scale flexible structure damping technology in damping technology as " the antiresonance theory is used " (Northeastern University's journal, 1994.4) of Liu Jie etc.But in Weighing system, also do not see the research report of using antiresonance principle vibration damping.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, a kind of band vibration absorber dynamic weighing rack is provided.Use the antiresonance vibration attenuation mechanism, by between sensor supporting body and the quantitative scale pan or check weighing conveyor, connecing damper and elastic supporting plate (perhaps support bar), and according to different range of weighing, adopt different damping coefficient damper, different elasticity coefficient back up pad and different quality supporting body, make sensor deflection fast and stable, thereby satisfy Dynamic Weighting requirement fast and accurately.
The present invention discloses a kind of band vibration absorber dynamic weighing rack, comprise stand base, weighing sensor, supporting body, the quantitative scale pan or check weighing conveyor, be characterized in: between supporting body and fixed base plate, be provided with weighing sensor, between supporting body and the quantitative scale pan or check weighing conveyor, connect adjustable dampers and elastic supporting plate, increased elasticity coefficient and damping ratio between weighing sensor and the quantitative scale pan or the check weighing conveyor.
Supporting body weight of the present invention can be regulated, the damper damping ratio can be regulated, the elastic supporting plate elasticity coefficient can be regulated, according to the antiresonance vibration attenuation mechanism, in that quantitatively the scale pan or check weighing conveyor weight are certain, to the certain limit material weighing, quantitatively the scale pan or check weighing conveyor are under certain exciting force effect, make the deflection shock range of weighing sensor reduce greatly, the concussion time shortens greatly.
Therefore, the present invention compares with prior art and Related product, weighing sensor causes that at reinforced impact of material or conveying motor oscillating etc. the deflection under the various exciting force effects is stable and quick, and can adapt to Dynamic Weighting under different exciting forces, different material and the different operating environment, horse structure is simple, cost is low, and is easy to utilize.
