Abstract
The utility model relates to a speed-adjustable feeding dosing belt weigher, which is equipment used for automatically dosing and compounding powdery, granular and massive materials. The speed-adjustable feeding dosing belt weigher is composed of a speed-adjustable feeding machine, a short belt weigher and a microcomputer control system, and can measure both continuously and intermittently. A material-conveying belt of the belt weigher does not directly pull materials from the bottom of a storehouse, which facilitates zero point correction by microcomputer control or manual intervention, and thus, weight signals are relatively stable, which is favorable to the improvement of the measuring accuracy.
Description
The utility model relates to a kind of speed governing feeding type dosing belt conveyer scale, is automatic ration feed and the dosing device that is used for powder, grain, lump material.
The dosing belted electronic balance that present China is used for commercial production mainly contains three kinds.
1, constant speed dosing belt conveyer scale, general adapted electric and magnetic oscillation feeding machine feed by changing electric and magnetic oscillation feeding machine feeding coal, is realized the purpose of dosing.This belt conveyer scale, because scale face cloth inequality, belt speed changes, its measuring accuracies of factor affecting such as dust accumulation, and the vibro-feeder noise is big, fragile, maintenance capacity is big, the wet stock knot that easily shaken, unfavorable blanking.Particularly electric current and feeding coal are not strict linear relation, and hysteresis phenomenon is arranged, and cause to adjust problem such as insensitive and be difficult to solve.
2, speed governing electronic constant belt conveyer scale is to realize dosing by the belt travelling speed of adjusting scale, its part of weighing is a holder rod formula scale frame, it is bigger that measuring accuracy is influenced by tension force, the processing of scale frame and installation quality, scale body length of belt etc., the I﹠M difficulty is big, price is higher, when particularly belt conveyer scale directly drew material at the bottom of the storehouse, adjusted inconvenient zero point.
3, the KLD-I type double-cantilever belt weigher (CN.8620.7515.7) developed of Chinese Academy of Sciences's mechanics adopts electric and magnetic oscillation feeding machine feed, and the scale body moves continuously, is interrupted weighing, can be with motion tracking, and the compensation metering makes the material proportion continous-stable.But electric and magnetic oscillation feeding machine frequent starting, noise is big, and the hourly output of belt conveyer scale is subject to certain restrictions.
The purpose of this utility model provides a kind of belt conveyer scale of speed governing feeding type, in order to overcome the shortcoming of above-mentioned three kinds of short belt conveyer scales.
The utility model " speed governing feeding type dosing belt conveyer scale " is made up of feeding machine, short belt conveyer scale and Control System of Microcomputer, it is characterized in that: a. feeding machine is a kind of speed controlled feeder, and it is made up of the buncher of the conveying device and being used to of mass transport to the short belt conveyer scale being adjusted dosing speed; B. short belt conveyer scale is single-cantilever or double-cantilever belt weigher, or for 1-4 load sensor of other use as pressurized sensitive element and length at the belt conveyer scale below 3 meters.
Above the device for transporting objects of said speed controlled feeder can be endless-belt formula conveyor, it and buncher constitute speed-governing belt formula feeding machine.Buncher is installed in the opposite side of endless-belt conveyor, can link to each other with the endless-belt frame of conveyer, also can make special stand in addition.By the endless-belt conveyor, material is fed and is given short belt conveyer scale, and its rate of feeding can be realized by the revolution of adjusting buncher.Feeding machine can be this custom-designed speed-governing belt feeding machine, also can select for use can the speed governing feed other equipment.Above-mentioned said speed controlled feeder is positioned at the top of short belt conveyer scale charging one side, capable of hoistingly hangs over material bin bottom or is installed on the fixing bearing.
Belt conveyer scale of the present invention can the separate unit scale uses as the equipment of dosing, also can many platform balances associatings use as industry batching and metering outfit.
Remarkable advantage of the present utility model is:
1, adopts speed-governing belt feeding machine feed, avoided the electric and magnetic oscillation feeding machine because the defective that self shortcoming brings for various short belt conveyer scale system when dosing, kept the strong point of various short belt conveyer scales itself simultaneously.
2, because the utility model draws material indirectly with the speed-governing belt feeding machine at the bottom of the storehouse, by system controlled by computer or manual intervention, can instantaneous zero load return to zero, thereby avoided original speed-governing belt scale system to change and adjust difficult shortcoming zero point owing to the belt tension that directly draws material to cause at the bottom of the storehouse, help improving measuring accuracy.
Accompanying drawing is the utility model " speed governing feeding type dosing belt conveyer scale " and principle of work synoptic diagram thereof, also is an embodiment of the present utility model.It is made up of the speed-governing belt feeding machine of double-cantilever belt weigher configuration and a cover Control System of Microcomputer of a continuous measurement.Material is discharged into endless-belt (5) by chute (2) in material bin (11), control activity flashboard (3) can be adjusted the height of materials on the strap surface, (4) be speed-governing belt machine endless-belt suspension bracket, buncher (1) drives endless-belt (5), material is fed to the double-cantilever belt weigher (6) that is in operating condition, weigh continuously by given flow, flow to next production link.When double-cantilever belt weigher (6) not during material feeding, load sensor (7) is in the state of not stressing, and output signal is zero.To microsystem (9), at this moment displayed value is zero on the CRT screen, adjusts to zero point as non-vanishing (but also manual intervention) automatically by amplifier (8).After double-cantilever belt weigher (6) material feeding, load sensor (7) is in stress, stressed size is directly proportional with weight of material, and whether evenly irrelevantly on the scale face, distribute with material, at this moment voltage signal that is directly proportional with weight of material of load sensor output (but also current signal), through amplifying and conversion, sending into microsystem (9) detects, when the detected value of weight of material on the scale face and setting value have deviation, microsystem (9) is adjusted buncher (1) revolution by controller (10), endless-belt (5) fed to be transferred to the material of double-cantilever belt weigher (6) equal or level off to setting value, like this, automatically instantaneous feeding coal is maintained to produce and go up on the desired setting value, just realized the purpose of native system automatic ration feed.
When the instantaneous stall of buncher (1), endless-belt (5) is feeding not, at this moment not material feeding on the scale face of double-cantilever belt weigher (6), empty scale operation, load sensor (7) output signal voltage (or electric current) is zero, as non-vanishing, can be by microsystem (9) (or manual intervention regularly also can be at random) suppressed zero automatically, so just eliminated the measurement deviation that causes because of dust accumulation or amplifier zero point drift.
