Background technology
It is one of equipment special of float glass moulding that flashboard is regulated in the flow liquid road that uses in the float glass process, in the flow liquid road flashboard aperture control loop that present domestic glass factory uses, all be to adopt incremental encoder and proximity sensor as flashboard aperture feedback signal, and after it is installed in actuating motor, the making precision, the influence of mounting accuracy that also have reducer casing and transmission shaft in the link, repeat poor performance, thereby make add up error become big, surpass manufacturing technique requirent, " disconnected plate " and great production and security incidents such as " buying securities with all one's capital " take place easily.Extensively retrieve at the problems referred to above, still find no improvement project this problem.
The utility model content
The purpose of this utility model is to become bigger, a kind of float glass flow liquid road regulator plate current amount control device that provides in order to overcome the cumulative errors that exists in the existing flashboard opening control device.
To achieve these goals, the utility model has been taked following technical scheme:
Float glass flow liquid road regulator plate current amount control device,
Float glass flow liquid road regulator plate current amount control device, the flow liquid road adjusting flashboard that comprises two vertical shafts and be connected the vertical shaft upper end, the vertical shaft lower end is connected with screw-threaded shaft elevator on being arranged on frame, it is characterized in that: described flow liquid road regulator plate current amount control device is by dcs, be arranged on the magnetic grating chi on the frame, data-switching and divider, two digital display meters are formed, dcs, data presentation table and magnetic grating chi are connected with divider to transmit and shows signal with data-switching, and the magnetic grating chi magnetic head in the magnetic grating chi is installed on the vertical shaft.
The utility model adopts technique scheme, and its advantage is:
1. the closed magnetic grating chi of the utility model employing is directly installed on the vertical shaft error of having avoided intermediate link to cause.
2. bus form is adopted in the signal transmission, distribute to digital display meter and control system, guarantee that its aperture at instrument and control system signal and on-the-spot flashboard is in full accord, thereby eliminated cumulative errors, avoid taking place " disconnected plate " and great production and security incidents such as " buying securities with all one's capital ".
Description of drawings
Fig. 1 is the synoptic diagram of float glass flow liquid road regulator panel assembly;
Fig. 2 is a flow liquid road flashboard control device schematic diagram;
Fig. 3 is that the K of Fig. 1 is to zoomed-in view.
Embodiment
The utility model is used for floatation glass production line, be arranged on place, glass melter flow liquid road, accurately control the flow of glass solution by the aperture of control flow liquid road flashboard, and the aperture memory capability of flashboard is very strong, after power failure, artificial on-the-spot shift position occurring, all can reflect actual position really, regulate the aperture of flashboard by DCS, simple to operation, this scheme is safe and reliable.
As shown in Figure 1, the flow liquid road flashboard control device that the utility model relates to, mechanical mounting portion wherein is made up of runner flashboard 8, vertical shaft 9, magnetic grating chi 5, magnetic grating chi magnetic head 5a, screw-threaded shaft elevator 11, synchronous motor 12, reducer casing 13, transmission shaft 10.Two vertical shafts 9 are connected on the screw-threaded shaft elevator 11, and screw-threaded shaft elevator 11, synchronous motor 12 and speed reduction unit 13 are installed on the frame, and by transmission shaft 10 turn-screw lifters 11.Magnetic grating chi 5 is arranged on the frame, the magnetic grating chi magnetic head 5a in the magnetic grating chi is installed on the vertical shaft 9.
As shown in Figure 2, the utility model is made up of dcs (DCS) 1,1# data presentation table 2,2# data presentation table 3, data-switching and divider 4, closed magnetic grating chi 5, low-voltage circuit breaker 6, low-voltage circuit breaker 7.Dcs (DCS) 1,1# data presentation table 2,2# data presentation table 3 and closed magnetic grating chi 5 are connected with divider 4 to transmit and shows signal with data-switching, and they all are and the utility model ingredient.
As shown in Figure 3, what screw-threaded shaft elevator 11 was selected for use is standard component, and it is the turbine nut structure, and this structure will rotatablely move and be converted to moving up and down of leading screw.Be that leading screw part cooperates with turbine in the screw-threaded shaft elevator 11 and makes turbine rotation in the transmission shaft 10, nut in the turbine then cooperates with leading screw 11a in the screw-threaded shaft elevator 11, leading screw 11a does not rotate because nut forwards to, so leading screw 11a can only be rectilinear motion up and down, leading screw 11a upper end is connected with vertical shaft 9 by shaft coupling 9a, magnetic grating chi magnetic head 5a is fixed on the vertical shaft 9, it and runner flashboard 8 synchronization liftings that are connected vertical shaft 9 upper ends, magnetic grating chi 5 just can be read runner flashboard 8 lifting apertures accurately signal.
Referring to Fig. 2, above-mentioned lifting aperture signal is transferred to data-switching and divider 4 through shielded cable, signal passes through a series of 4～20 milliamperes of (mA) signals that are transformed in data-switching and divider 4, adopt bus form, signal is divided into three the tunnel: the first via is transferred to 1# data presentation table 2, uses for local operation and observation flow liquid road flashboard aperture; The second the tunnel is transferred to 2# data presentation table 3, uses for pulpit operation and observation flow liquid road flashboard aperture; Third Road is transferred to cloth formula control system (DCS), and for writing control flow liquid road flashboard aperture program, operation and observing its aperture and use, all signal wires all adopt shielded cable.
