Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of glass-ceramic manufacturing equipment, and particularly relates to a material receiving tray suitable for glass-ceramic calendering forming process, which is suitable for the case that the glass-ceramic melting material channel discharge port has no gate plate. BACKGROUND

[0002] In the production and manufacturing process of microcrystalline ultra-thin glass products at home and abroad, the recovery and utilization process is very important due to the high cost of raw materials of the glass liquid, especially in the glass forming area. The common forming method of microcrystalline ultra-thin glass is calendering forming (i.e. front and rear rollers), and the use of calendering forming usually leads to waste of glass liquid and increases the difficulty of forming process debugging. Secondly, due to the high temperature of the glass liquid (usually above 1200℃), the small discharge amount (usually ≤10t / d), the small discharge pipe diameter, and the narrow space of the forming workshop, the microcrystalline glass discharge port (usually vertical feeding) cannot normally use the gate plate device for plugging, and the glass liquid will continue to flow out, thereby increasing the difficulty of forming machine changing, roller changing, and abnormal process debugging (glass liquid sticking to the roller, scale falling off, calendering roller stopping, etc.). In order to solve this problem, in the known prior art, a horizontal material receiving tray (as shown in Figure 6 , thermal insulation cotton is laid in the horizontal material receiving tray during use) or an inclined chute is usually used to collect or drain the glass liquid to the outside of the forming area, but the actual effect is often not ideal when using the above devices for material receiving or draining. For example, (1) the microcrystalline glass liquid is high in temperature and inconvenient to operate, and in the process of draining, the glass liquid is easy to splash and cause personnel scalding, and the glass liquid will also be wasted due to the splash; (2) the horizontal material receiving tray is heavy to operate, and the tray capacity is small, and the forming workshop is narrow, which often leads to that the glass liquid is full before the completion of machine changing, roller changing, or abnormal process debugging, thereby indirectly reducing the operation time of the forming personnel and increasing the probability of production accidents (because the glass liquid overflow is easy to stick to the roller); (3) the horizontal material receiving tray is easy to deform when used at high temperature due to the ordinary material, thereby affecting the service life and use effect (such as uneven placement of the material receiving tray, small capacity, etc.).

[0036] The working principle of the utility model is as follows: the utility model provides a material receiving tray suitable for microcrystalline glass calendering forming process, which is composed of a material receiving upper tray 1, a material receiving lower tray 2, a height-adjustable connecting piece 8, a shielding assembly and a cooling assembly; in the process of producing microcrystalline ultra-thin glass by using the calendering forming method, the working principle between the structures includes the following contents.

[0037] Firstly, compared with a horizontal material receiving tray, the material receiving tray body 16 is made of heat insulation cotton, which can be used for a long time under high temperature environment, and has a lighter weight and a larger volume under the same size.

[0038] Secondly, by using the height-adjustable connecting piece 8, the use positions of the material receiving upper tray 1 and the material receiving lower tray 2 can be fixed, and the height difference between the two can be adjusted, so as to realize the purpose of flexibly adjusting the glass liquid 17 recovery capacity of the material receiving tray; it should be noted that the microcrystalline ultra-thin glass calendering forming machine has a smaller volume than the photovoltaic glass calendering machine, and the structure design of the material receiving tray body 16 can be placed above the calendering roller of the calendering forming machine 19, used for recovering the glass liquid 17 discharged from the discharge pipe 18 (as shown in the accompanying drawings), and parallel to the calendering roller bearing seat of the calendering forming machine 19; since the height difference between the material receiving upper tray 1 and the material receiving lower tray 2 can be adjusted through the height-adjustable connecting piece 8, the material receiving tray body 16 has telescopic performance, which can ensure normal material receiving and indirectly increase the time of forming operation (machine changing, roller changing and abnormal process debugging, etc.) by increasing the volume. Figure 7 It should be noted that the material receiving upper tray 1 and the material receiving lower tray 2 can be connected through the height-adjustable connecting piece 8, so that the height difference between the two can be adjusted, which means that the material receiving tray body 16 has telescopic performance, which can ensure normal material receiving and indirectly increase the time of forming operation (machine changing, roller changing and abnormal process debugging, etc.) by increasing the volume.

[0039] Again, by using the water baffle 3, it can prevent the water splash to the glass liquid 17 in the receiving process, the operator is easy to be scalded by the glass liquid 17 and the water vapor, and the safety of the glass forming operation is improved; in addition, combined with the synergistic effect of the cooling water tank 4, the water inlet joint 5 and the water outlet joint 14, the bottom of the receiving tray body 16 can be cooled, which plays a role in local cooling, preventing the glass liquid 17 from adhering and the receiving tray from deforming; and by using the first handle 6 and the second handle 7, the operator can easily operate the receiving tray body 16.

[0040] In addition, in the actual use process of the receiving tray body 16, high-temperature-resistant heat preservation cotton can be laid in the receiving tray body 16 to prevent the glass liquid 17 from directly contacting the receiving tray body 16 and to avoid the deformation of the receiving tray body 16.
