Abstract
The utility model discloses a speed variable feeding device for a granular material quantity electronic scale, which is composed of an electromagnetic vibrating feeding mechanism and a discharging control mechanism. The utility model can accomplish selecting two working status of rough feeding and fine feeding with changing the vibration frequency and the vibration amplitude of the electromagnetic vibrating feeding mechanism. The material controlling plate of the discharging control mechanism can accomplish the adjustment of a big and a small openings, so the utility model can adapt the different requirements of rough and fine feeding. The utility model has the advantages of small size, simple structure and low manufacture cost.
Description
The utility model relates to a kind of electronic constant and claims, the charging gear that particularly a kind of granule materials electronic constant claims.
The granule materials electronic constant claims to be widely used in agricultural seed supply department, food, the first-class enterprise of change, is the key equipment of granule materials automatic quantitative packing line.Usually the granule materials electronic constant claims charging gear to be made up of two cover electro-vibrating feeder structures, satisfies the needs of thick smart two kinds of feeds respectively.The structural shape of this device can be divided into two kinds again: the one, two cover electro-vibrating feeder structures are placed side by side side by side, this structural shape not only takes up space bigger, and it is inhomogeneous to cause material to stack, and scale hooper is laid particular stress on, thereby have influence on weighing precision in the scale hooper that electronic constant claims; The 2nd, with the folded up and down row of two cover electro-vibrating feeder structures, this structural shape not only takes up space bigger, and needs to increase a cover pay-off, the electro-vibrating feeder structure feeding of giving these two intussusceptions row, thereby complex structure, cost height.
The purpose of this utility model is: the defective that exists at above-mentioned prior art proposes the charging gear that a kind of volume is little, simple in structure, cost is low granule materials electronic constant claims.
The speed change charging gear that the granule materials electronic constant that the utility model proposes claims is made up of electro-vibrating feeder structure and discharging control gear, its key problem in technology is: the feeder trough of electro-vibrating feeder structure is connected with pedestal by laminated spring, armature is connected with feeder trough, the feed electromagnet is installed on the pedestal, can realize the selection of two kinds of duties: the one frequency is that 3000 times/minute, amplitude are 0.8～1.5 millimeter, and its two frequency is that 3000-6000 time/minute, amplitude are 0.5～1.0 millimeter; The crop control plate of discharging control gear can be realized two kinds little adjustings with aperture of size.
Because the speed change charging gear that the granule materials electronic constant that the utility model proposes claims is only realized thick smart two kinds of feeds with a cover electro-vibrating feeder structure, so this device bulk is little, simple in structure, cost is low; The scale hooper that electronic constant claims can not produce and lay particular stress on, thereby can not influence weighing precision.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the structure principle chart of the speed change charging gear that claims according to the granule materials electronic constant that the utility model proposes.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
This speed change charging gear is made up of electro-vibrating feeder structure 12 and discharging control gear 8.Electro-vibrating feeder structure 12 comprises feeder trough 1, laminated spring 4, armature 3 and pedestal 11, and feeder trough 1 is connected with pedestal 11 by laminated spring 4, and armature 3 is connected with feeder trough 1, and feed electromagnet 2 is installed on the pedestal 11.The power supply of feed electromagnet 2 is the half-wave rectification alternating current, by changing the selection that power source voltage or frequency realize 12 two kinds of duties of electro-vibrating feeder structure.Electronic scale is when carrying out weighing work, electro-vibrating feeder structure 12 carries out thick feed earlier, this moment, feed electromagnet 2 supply voltage was higher and frequency is lower, made that the vibration frequency of electro-vibrating feeder structure 12 is that 3000 times/minute, amplitude are 0.8～1.5 millimeter.When thick feed during near the weighing value set, the micro computer of electronic scale switches to low voltage and upper frequency with the power supply of feed electromagnet 2, make that the vibration frequency of electro-vibrating feeder structure 12 is that 3000～6000 times/minute, amplitude are 0.5～1.0 millimeter, to realize smart feed.When the weighing value that equals to set, the micro computer of electronic scale is with the dump of feed electromagnet 2, and electro-vibrating feeder structure 12 stops feed, has so far finished the feed overall process of a weighing.The discharging control gear 8 of present embodiment is made up of support 9, material controlling electromagnet 10, connection rod member 5, crop control plate 7 and spring 6, material controlling electromagnet 10 is installed on the support 9, connect rod member 5 and be subjected to the control of material controlling electromagnet 9 and down collaborative at spring 6, realize adjusting two kinds of different opening of crop control plate 7 sizes.When electro-vibrating feeder structure 12 carried out feed, the micro computer of electronic scale was being controlled the break-make of material controlling electromagnet 10 power supplys simultaneously, made crop control plate 7 be in two kinds of aperture positions of size respectively, to adapt to the different requirements of thick smart feed to crop control plate 7 apertures.
