[0002] In most domestic production and manufacturing processes that use glass forming technology, the initial microcrystalline glass product is usually obtained by forming and annealing the glass liquid flowing out of the discharge port. In the process after forming and before annealing, the temperature of the forming area has a crucial impact on the quality of the microcrystalline glass product. For example, in the calendering forming method, after the glass liquid is extruded and formed by contact with the calendering rollers, it is then put into the area of the annealing furnace (referred to as: transition area). The glass plate is easily affected by the external temperature. If the ambient temperature is too low and the required temperature for forming and insulation is not reached, the glass plate is prone to excessive warping, curling, and cold cracking, thereby affecting the thickness, thickness difference and other parameters of the glass plate, and even causing the glass plate to explode after entering the annealing furnace.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0022] Reference Attachment Figure 1 A simple heat-insulating cover for a microcrystalline glass forming process comprises a heat-insulating cover shell 1, wherein an inlet 8 and an outlet are symmetrically provided on both sides of the heat-insulating cover shell 1, and heat-insulating elements for adjusting the ambient temperature in the transition zone are respectively provided at the inlet 8 and the outlet. A height-adjusting element for adjusting the height of the heat-insulating element is provided on the heat-insulating cover shell 1, and a cotton hanging element for fixing the heat-insulating material is provided inside the heat-insulating cover shell 1. That is, by providing the heat-insulating cover shell 1, the heat-insulating element, the height-adjusting element and the cotton hanging element, the heat-insulating and heat-insulating effect of the simple heat-insulating cover can be utilized to adjust the ambient temperature in the transition zone, so as to achieve the effect of efficiently isolating the temperature in the transition zone and improving the heat-insulating performance, thereby achieving the purpose of reducing defects in the finished microcrystalline glass product. For example, for calendering molding, in the production process of the finished microcrystalline glass product, after the glass plate is squeezed and formed by the calendering roller and led to the transition zone, the simple heat-insulating cover is manually installed in the transition zone. As the glass sheet passes through the transition zone, the ambient temperature within it can be controlled by adjusting the height of the height-adjusting element, improving thermal insulation and heat preservation capabilities, effectively reducing the occurrence of glass sheet defects, and enabling the glass sheet to be better guided out of the exit of the simple insulation cover and into the annealing lehr, ultimately resulting in a perfect finished glass-ceramic product. The structural design of the simple insulation cover addresses actual production issues, aiming to improve the insulation effect of the transition zone and reduce defects in the finished glass product.
[0023] In one possible implementation, see the attached Figure 1 The heat preservation cover shell 1 is a rectangular structure that is convenient for storing and accommodating glass plates. It is similar in shape to the glass plates, which makes it easy for operators to place the glass plates inside, and the convenience of use is improved to a certain extent. In addition, in order to facilitate manpower to install the simple heat preservation cover to the transition area, handles 9 are also symmetrically arranged on the top of the heat preservation cover shell 1.
[0024] In one possible embodiment, the thermal insulation cover shell 1 is made of refractory material or heat-resistant material. The thermal insulation cover shell 1 can be made of refractory material (for example, molybdenum, tungsten, chromium, etc.) or heat-resistant material (for example, silicon carbide, boron nitride, etc.) to play the role of heat preservation and insulation.
[0025] In one possible embodiment, guide rails 6 for limiting the vertical movement direction of the thermal insulation element are respectively provided at the inlet 8 and the outlet. The guide rails 6 are provided on the side of the inlet 8 or the outlet to facilitate limiting the vertical movement direction of the thermal insulation element, thereby avoiding deviation of the movement direction of the thermal insulation element.
[0026] In a possible implementation, the thermal insulation element is a gate plate 2 , and the gate plate 2 is slidably connected to the guide rail 6 .
[0027] In a possible embodiment, a plurality of height adjustment through holes 3 are provided on the gate plate 2, and the positions of the height adjustment through holes 3 correspond to the positions of the height adjustment elements. When adjusting the ambient temperature in the transition area, the height of the gate plate 2 can be adjusted by plugging the height adjustment element into the corresponding height adjustment through hole 3 according to the shape and size of the glass plate and the preset ambient temperature threshold in the transition area (for example, 70°C. After the glass plate is placed in the heat preservation cover shell 1, the surface temperature of the glass plate can be observed by a helmet-type infrared thermal imager). The size of the opening space of the inlet part 8 is changed, thereby achieving the functions of adjustment, heat preservation and heat insulation.
[0028] In one possible implementation, see the attached Figure 1 The height adjustment element includes a pin 5 and multiple limit rings 4. The multiple limit rings 4 are arranged in parallel at the upper end of the heat preservation cover shell 1. The pin 5 includes a handheld vertical section and a height adjustment horizontal section. The end of the height adjustment horizontal section away from the handheld vertical section passes through the limit ring 4 and is plugged into the height adjustment through hole 3. By setting the limit ring 4, the moving direction of the height adjustment horizontal section can be limited so that it can only move in the direction toward or away from the gate 2, thereby improving the convenience of human operation and control process.
[0029] In one possible embodiment, the gate plate 2 is made of a refractory material or a heat-resistant material. The gate plate 2 can also be made of a refractory material (for example, molybdenum, tungsten, chromium, etc.) or a heat-resistant material (for example, silicon carbide, boron nitride, etc.), with a temperature resistance of at least 400 degrees and a maximum of 1450 degrees, which plays a role in heat preservation and insulation. In addition, in order to facilitate the adjustment of the use height of the gate plate 2, a hand plate 10 is provided at its upper end, which facilitates the operator to move the gate plate 2 up and down through the hand plate.
[0030] In one possible implementation, see the attached Figure 1-2 The cotton hanging element is a cotton hanging hook 7, which is made of refractory material or heat-resistant material. The cotton hanging hook 7 can also be made of refractory material (for example, molybdenum, tungsten, chromium, etc.) or heat-resistant material (for example, silicon carbide, boron nitride, etc.). The temperature resistance is at least 400 degrees and can reach up to 1450 degrees. It is fixedly installed on the inner surface of the insulation cover shell 1 and is used to fix insulation materials such as insulation cotton.
[0031] In one possible implementation, see the attached Figure 1-2 The hook angle of the cotton hanging hook 7 is 45°-135°, preferably 90°, which can prevent the thermal insulation material (such as thermal insulation cotton) from falling off easily after being hung.
[0032] In a possible embodiment, the distribution of the cotton hanging hooks 7 inside the heat preservation cover shell 1 can refer to the following formula: N=S / d / 0.1, where N is the number of cotton hanging hooks 7 installed in each row in the horizontal direction, and S is the surface area of the heat preservation cover shell 1 in cm. 2 , d is the width of the glass plate, in cm, 0.1 is the transverse coefficient; n=S / d / 0.2, where n is the number of vertical installations of each column of cotton hanging hooks 7, in pieces, and S is the surface area of the insulation cover shell 1, in cm 2 , d is the width of the glass plate, in cm, 0.2 is the vertical coefficient. It should be noted that after the cotton hanging hook 7 is installed and laid out, it is only used to produce a glass plate production line of one specification and size. If a glass plate of another specification and size needs to be produced, the cotton hanging hook 7 needs to be re-laid inside the insulation cover shell 1 according to the above formula.
[0033] The working principle of the present invention is as follows: The present invention provides a simple thermal insulation cover for the microcrystalline glass forming process, which consists of a thermal insulation cover shell 1, a gate plate 2, a pin 5, a limit ring 4 and a cotton hanging hook 7. When the simple thermal insulation cover is in use, it is installed in the transition area by manpower. After the glass plate is squeezed and formed by the calendering roller and led to the transition area, it is placed in the simple thermal insulation cover. Through the synergistic effect between the pin 5 and the gate plate 2, the ambient temperature in the transition area can be adjusted, and the rapid loss of temperature after the glass plate is formed and the occurrence of glass plate defects can be effectively reduced. Subsequently, the glass plate is led out from the outlet of the simple thermal insulation cover by manpower and then enters the annealing kiln, thereby obtaining the final intact microcrystalline glass product, so as to improve the plate surface condition after the glass is formed (glass plate surface defects, warping value, thickness difference, etc.), thereby effectively reducing the product defective rate and production cost.
[0034] In summary, the utility model provides a simple thermal insulation cover for the microcrystalline glass forming process, which has a simple and compact structure, is easy to operate and use, and makes the human operation and control process safe and effective. It is simple to disassemble and can effectively reduce the lack of ambient temperature in the transition area of the microcrystalline glass finished product, thereby achieving the effect of reducing the defects of the microcrystalline glass finished product, thereby ensuring production safety and improving the product yield.

For those skilled in the art of the present invention, without departing from the concept of the present invention, they can make several simple deductions or substitutions, which should be considered to fall within the scope of protection of the present invention.
