Abstract
The utility model discloses a jolt-feeding weightlessness steelyard. The jolt-feeding weightlessness steelyard comprises a weightlessness steelyard, in which a jolting device is arranged, wherein the jolting device is electrically connected with a controller for controlling amplitude of the jolting device; and the controller is electrically connected with a PLC (Programmable Logic Controller); and as the jolt-feeding weightlessness steelyard is controlled by using the PLC as the controller, the jolt-feeding weightlessness steelyard disclosed by the utility model can be used for achieving small-amount feeding with high accuracy and has the advantages of low cost, simple structure and convenience in operation.
Description
Technical field
The utility model relates to a kind of weightless scale, relates in particular to the weightless scale of a kind of top shake feed.
Background technology
The batch feed mode of traditional powdery or small particles material has constant feeder, weightless scale, bucket scale etc.; Wherein, Weightless scale is the automatic weighing-appliance that a kind of mode through static weighing realizes the high precision continuous dosing of very; It can be done the material that looses to powder, particle, sheet etc. and carry out reliable, accurate and stable feed, reduces the waste of material and the consistance of raising potpourri; But this kind mode less than 1kg, is difficult to reach accuracy requirement as in batches when the short run feed.
The utility model content
The purpose of the utility model is to the problems referred to above, provides a kind of top shake feed weightless scale, and it has simple in structure, is easy to realize the characteristics of accurate feeding.
The purpose of the utility model is to realize through following technical scheme:
The weightless scale of a kind of top shake feed comprises weightless scale, is provided with shake device in top in the said weightless scale, and the control device of this top shake device amplitude of said top shake device and control is electrically connected.
Preferably; Said control device is for the professional control device of exploitations such as single-chip microcomputer, DSP, PLD, ARM or be provided with the industrial computer of integrated circuit board; Most preferred; Said control device comprises controller and PLC, and said PLC is electrically connected with controller, and said controller is electrically connected with top shake device.
The beneficial effect of the utility model does, the weightless scale of said top shake feed adopts PLC as the controller control top weightless scale of feed that shakes, and can realize high-precision short run feed, and cost is low, and is simple in structure, easy to operate.
Description of drawings
Fig. 1 is the weightless structural representation of claiming of the utility model top shake feed.
Among the figure:
1, weightless scale; 2, controller; 3, PLC.
Embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through embodiment.
Please with reference to shown in Figure 1, in present embodiment, the weightless scale of a kind of top shake feed comprises weightless scale 1, the said weightless top shake device of claiming to be provided with in 1, and the controller 2 of this top shake device amplitude of said top shake device and control is electrically connected, and said controller 2 is electrically connected with PLC3.
The shake feed weightless controller 2 of claiming that the shake amplitude is run in the control of being furnished with in top receives the analog signals of 4-20mA; Value is set the amplitude of top shake in view of the above; This 4-20mA signal is provided by PLC3 analog quantity output point, and controller 2 receives outside start stop switch signal, the weightless start and stop of claiming of control top shake feed.Start stop signal is that the switching value output point through PLC3 provides.
The course of work of the utility model is: on PLC3, sets feeding coal, and sends enabling signal to the weightless controller of claiming 2 of top shake feed, and starting outfit, feeding coal is set to the high speed feed simultaneously, and material amount down is through PLC3 calculating; When the residue feeding coal reaches the middling speed amount of parameter setting, blanking velocity is transferred to the feed of middling speed; When the residue feeding coal reaches the low speed amount of parameter setting, blanking velocity is transferred to the low speed feed; When the residue feeding coal reaches the amount of stopping of parameter setting, stop feed, may produce the inertia that lags behind or have blanking in the stopping process, cause also not reach feeding coal when shutting down.These three parameters are set through PLC3, and are definite when debugging at the scene, according to weightless the different of bodily form formula and specified feeding coal, the value possibility difference that these parameter regulation go out claimed of the shake feed of running.The setting of parameter and the setting of feeding coal, top shake feed be weightless to be claimed that start and stop etc. operate in the screen that is connected with PLC3 or the host computer and operates.
Above embodiment has just set forth the ultimate principle and the characteristic of the utility model; The utility model is not limited by the foregoing description; Under the prerequisite that does not break away from the utility model spirit and scope; The utility model also has various variations and change, and these variations and change all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (3)
1. the weightless scale of top shake feed comprises weightless scale, it is characterized in that: be provided with shake device in top in the said weightless scale, the control device of this top shake device amplitude of said top shake device and control is electrically connected.
