Description
Technical Field
The utility model relates to the technical field of float glass manufacturing, in particular to a glass belt thickness monitoring device of a tin groove section in a float glass process.
Background
When manufacturing float glass, various raw materials are melted at high temperature in a kiln to form molten glass, then the molten glass enters a tin bath, is spread and formed under the drawing of an edge roller, passes through a transition roller table, enters an annealing kiln, and is cooled and annealed. The thickness of the glass needs to be controlled in a tin bath through an edge roller, and if the thickness of the glass is not properly controlled, the glass is broken and the thickness of the glass does not meet the requirement.
For monitoring glass broken plates, a camera is arranged at an outlet of a transition roller table at present, and observation is carried out through human eyes. However, human eyes look at the images transmitted by the camera for a long time and stare at a computer for observation in 24 hours, so that negligence is inevitable.
For monitoring the thickness of glass, the conventional method is to perform online sampling inspection and manual inspection by taking a glass sheet after a glass ribbon passes through an annealing kiln and is cut and broken off. If the thickness of the glass ribbon fluctuates, a period of time is needed to discover the fluctuation, and a pair of edge rollers in the tin bath is adjusted according to experience to adjust the thickness of the glass ribbon. By such operation, the adjustment time is long, and the production loss is large.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a glass of tin bath section takes thickness monitoring devices in float glass process, the device can monitor the thickness of glass area in the tin bath section in real time, in time discovers disconnected board and glass thickness defect, reduces the adjust time.
The utility model provides a technical scheme that its technical problem adopted is:
a glass strip thickness monitoring device of a tin bath section in a float glass process comprises a group of ultrasonic thickness gauges, wherein the ultrasonic thickness gauges are arranged above a tin bath and are distributed at intervals along the width direction of the tin bath; the ultrasonic thickness gauge is respectively connected with a PLC (programmable logic controller) for controlling the tin bath section edge roller, the ultrasonic thickness gauge feeds the detected thickness of the glass strip back to the PLC, and the PLC controls and adjusts the edge roller according to the received thickness of the glass strip; and the output interface of the PLC is also connected with an alarm.
The utility model has the advantages that the ultrasonic thickness gauge can detect the thickness of the glass belt in real time by utilizing ultrasonic waves and feed the detection result back to the PLC controlling the edge roller, and the PLC carries out closed-loop control after comparing the preset thickness of the glass belt with the received real-time thickness of the glass belt, so that the glass belt is adjusted in time; and the plate breaking condition of the glass belt can be found in time; the reliability of production is improved.
Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic distribution diagram of the ultrasonic thickness gauge of the present invention.
Detailed Description
Referring to fig. 1 and 2, the utility model provides a glass strip thickness monitoring device of a tin bath section in a float glass process, which comprises a group of ultrasonic thickness gauges 1, wherein the ultrasonic thickness gauges 1 are arranged above the tin bath 2 and are distributed at intervals along the width direction of the tin bath 2; the ultrasonic thickness gauge 1 is respectively connected with a PLC4 for controlling the tin bath section edge roller 3, the ultrasonic thickness gauge 1 feeds back the thickness of the detected glass belt 5 to the PLC4, and an output interface of the PLC4 is also connected with an alarm 6.
The ultrasonic thickness gauge 1 can detect the thickness of the glass belt 5 in real time by utilizing ultrasonic waves, and feeds a detection result back to a PLC4 for controlling the edge roller, and the PLC4 compares the preset thickness of the glass belt with the received real-time thickness of the glass belt and then performs closed-loop control to adjust the glass belt in time; if the ultrasonic thickness gauge detects that the thickness is 0, the condition that the plate is broken is shown, and the PLC4 controls the alarm 6 to give an alarm at the moment, so that the worker can process the plate in time.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the invention is not limited to the embodiments described herein, but is capable of other embodiments according to the invention, and may be used in various other applications, including, but not limited to, industrial. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments by the technical entity of the present invention all still belong to the protection scope of the technical solution of the present invention.
