Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings and specific embodiments.
In the following description, references to "one embodiment," "an embodiment," "one example," "an example," etc., indicate that the embodiment or example so described may include a particular feature, structure, characteristic, property, element, or limitation, but every embodiment or example does not necessarily include the particular feature, structure, characteristic, property, element, or limitation. Moreover, repeated use of the phrase "in accordance with an embodiment of the present application" although it may possibly refer to the same embodiment, does not necessarily refer to the same embodiment.
Certain features that are well known to those skilled in the art have been omitted from the following description for the sake of simplicity.
According to an embodiment of the present application, there is provided a relief glaze spraying process, as shown in fig. 1, including the steps of: soaking the embossed stained paper in normal-temperature water for 3-5 minutes, taking out the stained paper, and putting the stained paper into a labeling disc (on the basis of easy sliding of a label). And attaching the soaked label to a label position of the glass bottle for labeling, and scraping water. After labeling is finished, wiping off impurities and water stains on the surfaces of the glass bottle and the label by using a towel, waiting for natural drying, tearing off surface oil on the surface of the glass bottle, and wiping off the impurities, the watermarks and the like on the surfaces of the glass bottle and the label by using the towel. Then the relief is baked at 120-190 ℃ for 20-50 minutes (the process is simultaneously suitable for spraying glaze after the relief is directly dried without baking). And then, carrying out glaze spraying treatment on the glass bottle, wherein the glaze spraying process temperature is 150-220 ℃, the net speed is 20-60Hz, the time is about 30-120 minutes, and the glass bottle can be directly packaged and warehoused as a finished product without subsequent processing. The baking temperature is 150-220 deg.C and the time is 40-120 min (or 2-10 min for quick curing).

(8) Output regulating/GPS unit
The output regulation of the gas catalytic infrared oven is by "pulsing" the pressure of the fuel flowing into the burner assembly at regular intervals, two gas pressure controllers being installed in the supply duct of the burner assembly. The gas pressure controller is regulated to the working pressure "high pressure" in the main supply pipe and the "low pressure" in the bypass. The switching between the two operating pressures is effected by a pilot-operated shut-off valve in the main supply line. Meanwhile, in order to manually control the working pressure, a compression pressure gauge is arranged in the GPS device.
(9) Operation of GPS unit
a. If the piloted shut-off valve in the main fuel assembly main gas supply pipe is opened, gas flows to the combustor assembly via the high pressure gas pressure controller. The burner assembly operates at high fuel pressure and produces maximum heating power; if the pilot shut-off valve in the main gas supply pipe of the gas assembly is closed, gas will flow into the burner assembly through the low pressure gas pressure controller in the bypass. The burner assembly operates only at low fuel pressures and produces minimal heating power.
b. The system comprises the following components: 1. high fire operation; 2. low fire operation (standby state). In the pulse control mode of the pilot operated shutoff valve, the output regulation of the burner assembly is controlled by the PLC. The output regulation output regulates the switching value of the proportional control valve. If the piloted shut-off valve is operating at 100% of the base clock rate, the combustor assembly will operate at "100% output". To reduce the output, the basic clock frequency is interrupted and the pilot-operated shutoff valve closes the interruption interval. The ratio of the time that the valve is operated (open) to the time that the valve is not operating (closed) provides information about the percentage of the burner assembly output. If the valve is operating in one-half of the base clock frequency, the burner assembly is operating at 50% output.
c. The high pressure and low pressure fuel pressure of the GPS unit are factory set as the operating values of the air pressure controller of the GPS device. If a correction is required, the fuel pressure can be readjusted on the gas pressure controller.
