Technical field
The utility model belongs to a kind of material metering system, particularly a kind of system that the flow of glue class I liquid I is measured.
Background technology
Existing material metering particularly liquid gaging system generally adopts pipeline flow metering method; This method is incipient or accurately more stable; But receive the influence of material viscosity; Particularly grown stop time sometimes, and the material of pipeline the inside has partial coagulation, makes pipeline flowmeter malfunctioning easily like this; The product that has is bitubular coding metering, and the major defect of this metering method has several aspects: though 1, metering cylinder has two, and is too little, make the increased frequency that adds material, electrical equipment easy to wear; 2, this metering method needs the artificial table of pinching to calculate and use volume, then according to volume calculated flow rate, troublesome poeration so again; And reaction is not current real-time instantaneous delivery; The operator just can not get the real-time and effective data like this, and control is got up cumbersome, can only control by experience.
Along with constantly raising up of industrial materials prices; The ratio that material accounts for total production cost also constantly improves, and is just paid attention to by enterprise like the control of resin added in the MDF, and each side's production board is often executed one or two kilograms of glue even more more; Article one, the production line of producing 50000 sides per year was just wasted at least tens tons glue in 1 year; Be worth hundreds thousand of units, not only cause huge waste, and the whether even quality of production that directly influences sheet material of applying glue.
Summary of the invention
For overcoming above-mentioned shortcoming; The utility model provides a kind of pair of loss of weight flow measuring system, adopts loss of weight formula metering method that material is carried out collection instantaneous and accumulative total, does not receive the factor affecting such as viscosity, curing conductive performance of material; Have precision height, good stability, characteristics such as easy care.
The purpose of the utility model is achieved in that the utility model comprises two cover weighing device and control device; Every cover weighing device includes a scale frame, a sensor and a material barrel; Control device comprises two valves under a control module and the control module control, the corresponding material barrel of each valve; Two material barrels are placed on respectively on each self-corresponding scale frame; Scale frame employing loss of weight formula metering method is carried out collection instantaneous and accumulative total to the mass flow of material barrel; Sensor through on the scale frame separately is transferred to control module with weight signal respectively, and control module is controlled handoff procedure and the by-pass valve control switch that two material barrels replace outputting material with this and accomplished the feed supplement process to material barrel.
As the further improvement of the utility model, described valve is installed in respectively on the feed supplement pipeline of each self-corresponding material barrel.
As preferably, the used instrument of described control module adopts the single-chip microcomputer instrument, fast operation, and strong interference immunity, easy to operate.
As preferably, described scale frame adopts all electronic structure scale body.
As preferably, described valve is an operated pneumatic valve, and CS process and speed are faster, and guarantees the degree of accuracy of metering.
The beneficial effect of the utility model is:
1, the utility model can be applicable to continuous coverage liquid, the volume and the weight of the shape solid feeding that looses, for example water, glue, powder, particle, sheet, thin slice and fiber have characteristics such as powerful, reliability height;
2, adopt loss of weight formula metering method, instantaneous delivery, cumulative amount etc. does not receive the influence of the characteristic of testee, as: the influence of viscosity, corrosivity etc.Application is quite extensive;
3, the use of two cover weighing devices can be stopped while feeding in raw material the error that the material real-time variation causes in the output procedure;
4, through high speed acquisition weight change value constantly, realize high-precision measuring, the control of flow, feeding capacity accumulative total;
5, handled easily person has not only practiced thrift great deal of raw materials to the control of material, has reduced production cost, and has improved product quality, makes properties of product stable, improves product percent of pass.

Embodiment
With reference to shown in Figure 1: the utility model comprises two cover weighing device and control device; Every cover weighing device includes a scale frame 1, a sensor 2 and a material barrel 3; Described control device comprises two valves 5 under a control module 4 and control module 4 controls; Valve 5 is installed in respectively on the feed supplement pipeline 6 of each self-corresponding material barrel 3, the feed supplement of control material barrel 3; The material barrel 3 of two content material is placed on respectively on each self-corresponding scale frame 1 and weighs; Material is earlier by output in first material barrel 3; Its scale frame 1 adopts loss of weight formula metering method earlier the mass flow of first material barrel 3 to be carried out collection instantaneous and accumulative total, through the sensor 2 on this scale frame 1 weight signal that collects is transferred to control module 4, when weight signal reaches the lower limit of setting; Control module 4 is through control feed supplement switching signal Open valve 5 switches; First material barrel 3 is carried out feed supplement, when material is added to the higher limit of default, turn off valve 5 switches; The simultaneity factor that first material barrel 3 weight signals reach lower limit switches to by outputting material in second material barrel 3; Same its scale frame 1 employing loss of weight formula metering method is carried out collection instantaneous and accumulative total to the mass flow of second material barrel 3; Sensor 2 through on this scale frame 1 is transferred to control module with the weight signal that collects; When weight signal reached the lower limit of setting, control module 4 carried out feed supplement through control feed supplement switching signal Open valve 5 switches to first material barrel 3; When material is added to the higher limit of default, turn off valve 5 switches; The simultaneity factor that second material barrel 3 weight signal reach lower limit is switched back again by outputting material in first material barrel 3; Two material barrels 3 like this are outputting material and the real-time weight signal of gathering two material barrels 3 alternately; Go round and begin again; Reach continuously and add up accurately, stop the error
that the material real-time variation causes in the output procedure of feed supplement limit, limit.
Supposing just to begin material barrel 3 weight that material is housed is M1; Sampling period is T, after a sampling period, claims to such an extent that the weight of material barrel 3 is M2; Then the computing formula of material instantaneous delivery is: instantaneous delivery=(M1-M2)/and T, the sampling period can freely be set as required.Can know that by above formula the mass flow that records does not receive feeding pipe, executes the wearing and tearing of material pump etc. or the influence of obstruction, this point is that propeller flowmeter, electromagnetic flowmeter etc. can't be accomplished.Therefore the data on flows that records through the utility model is very truly, accurately.
Described control module 4 used instruments adopt the single-chip microcomputer instrument; Described scale frame 1 adopts all electronic structure scale body; Described valve 5 is an operated pneumatic valve.
Above embodiment only is used to explain the utility model; But not to the restriction of the utility model; Under the situation of spirit that does not break away from the utility model and scope, can also make various variations, so all technical schemes that are equal to also belong to the category of the utility model.
