Description
Technical field
The present invention relates to a kind of modular construction belted electronic balance, be used to accomplish the dynamic weighing of solid bulk material.
Background technology
Continuous development along with Dynamic Weighing Technology; The belt conveyer scale product is widely used in industries such as tobacco, metallurgy, chemical industry, building materials, mine, harbour, logistics; It dynamically adds up precision and has reached 0.25% trade settlement requirement, and performances such as long-time stability, reliability have also obtained great raising simultaneously; But no matter be cantilevered, single lever type or the double lever type belt conveyer scale that utilizes lever principle, still do not have the floated structure belt conveyer scale of lever, its scale body all is the one-piece construction that adopts integral type, and is not enough below the scale body of this structure exists:
1. long-time stability are poor.New equipment is after use after a while; The capital occurs because factors such as belt deviation, cylinder incrustation, dust stratification, replacing parts; The situation that causes performance index such as degree of accuracy, stability to descend even serious overproof phenomenon takes place, has brought hidden danger for the long-term ordinary production of enterprise.
2. complete machine adjustment difficulty is big, consistance is poor.Because all parts all are to be fixed on the crossbeam or housing of scale body; Therefore all higher to the machine work precision and the technology matching requirements of parts; In case little bias appears in processing or assembly precision; The capital causes the overall performance of belt conveyer scale not reach requirement, thereby also just can't guarantee the consistance of every belt conveyer scale.
3. parts are safeguarded difficulty, incur loss through delay and produce.In the production use, if damage of components need change the time then this type of belt conveyer scale need spend more time and efforts; For example change a belt, generally need 4 maintenance mans to spend the time about 10 hours could belt be finished changing, tend to incur loss through delay normal manufacturing schedule like this.
4. the difficult cleaning of incrustation, influence stability.After belt conveyer scale uses a period of time; Because factors such as temperature, humidity, dust can be at drive roll, driven cylinder, metering carrying roller, fixedly form dirt on the parts such as carrying roller; And the difficulty of this type of belt conveyer scale cleaning incrustation is very big, but if the untimely cleaning of these dirts or clear up halfway words all can cause the decline of belt conveyer scale operation stability; Thereby influence the accumulative total precision of belt conveyer scale, and serious overproof situation occurs.
Summary of the invention
Its purpose of the present invention just is to provide a kind of modular construction belted electronic balance, thus the stable problem of performance index when having solved the belt conveyer scale long-time running.Have and safeguard simple, dismounting characteristics efficiently, and have functions such as continuous dynamic weighing, flux cumulating, flow control, belt deviation correction.The burden balance that can be used as on the production line use the metering target scale when also can be used for trade settlement.
The technical scheme that realizes above-mentioned purpose and take comprises scale body framework, and scale body framework one end is provided with the motor reducer group; Scale body framework is provided with blanking cover, striker plate and conveying belt; Also be provided with initiatively module, weighing platform module and slave module on the said scale body framework, said active module comprises drive roll, and drive roll is provided with sprocket wheel; Sprocket wheel connects the motor reducer group, and initiatively module is provided with manual deviation-adjusting carrier roller, automatic deviation rectifying device and guide rail; Said weighing platform module comprises the weighing platform framework, and the weighing platform framework is provided with studdle, counterweight, supporting seat and prime amplifier, and said supporting seat is provided with weighing carrier roller, and weighing carrier roller two ends are provided with LOAD CELLS; Said slave module comprises guide rail, idler roller, driven cylinder and fixing carrying roller; Said conveying belt is around between the drive roll and the driven cylinder on the slave module that are fixed on the active module.
Compared with prior art the present invention has the following advantages.
Owing to adopted the modular construction design, make that at first to change parts very convenient, quick, for example changing a belt only needs 2 maintenance mans just can accomplish whole operations within 20 minutes; Secondly; The dead angle can be accomplished fast, thoroughly do not stayed to the cleaning of dirt; No matter be drive roll, weighing carrier roller, still driven cylinder, fixedly carrying roller etc. all can be extracted the module of correspondence with clear water, alcohol etc. out easily and comprehensively clean and put in order from the slide rail of scale body; The 3rd, initiatively module, weighing platform module and slave module be as three critical components of belt conveyer scale, can adjust separately, correction and transient equilibrium, thereby can guarantee the height consistance of every belt conveyer scale; At last; The modular construction design simplification has also been accelerated the final assembly technology of belt conveyer scale; The maintenanceability that has also promoted simultaneously belt conveyer scale greatly can; For long-time stability, accuracy and the high reliability of belt conveyer scale operation lays a solid foundation, can under abominable work condition environment, bring into play effects such as accurate measurement, control stabilization, maintenance be convenient, safe and reliable for a long time for belt conveyer scale sufficient assurance is provided.
