[0026] The present utility model will be further described in detail below with reference to the accompanying drawings:

[0027] Embodiment 1

[0028] As Figure 1As shown in the figure, the present utility model provides a feeding sealing device for a liquid crystal substrate glass furnace, which includes: a cage 1, a flexible connection seal 2, a cylinder 3, a lever 4, a sealing hoop 5 and a connecting member 6. The outer shape of the cage 1 is circular, and there are threaded holes on both sides. The cage 1 is arranged at the upper end of the flexible connection seal 2. The flexible connection seal 2 is cylindrical in shape. At the same time, one end of the flexible connection seal 2 wraps the cage 1 and turns 1 to 2 weeks, and the other end is connected to the feeding port. The cylinders 3 are arranged on both sides of the flexible connection seal 2 and correspond to the positions where the threaded holes are located. The lever 4 is arranged on the side of the flexible connection seal 2 close to the cage 1. There are a positioning nut 41 and a fastening nut 42 on the lever 4. The fastening nut 42 is arranged at the upper end of the positioning nut 41. The connecting member 6 is L-shaped and includes a first connecting member and a second connecting member. The axis of the first connecting member is perpendicular to the axis of the second connecting member. The first connecting member is arranged on both sides of the upper end of the flexible connection seal 2 and is connected to the cage 1 through a fixing member. The fixing member passes through the first connecting member and the flexible connection seal 2 from inside to outside and is fixedly connected to the cage 1. In this embodiment, the fixing member is a screw or a bolt; the second connecting member is arranged between the positioning nut 41 and the fastening nut 42. The fastening nut 42 is arranged at the upper end of the positioning nut 41. The positioning nut 41 is used for positioning, and the fastening nut 42 is used for fastening. The positioning nut 41, the fastening nut 42 and the lever 4 are threadedly connected. The bottom of the flexible connection seal 2 droops naturally and is pre-hooped with a sealing hoop 5. During the process of the cage 1 rising with the cylinder 3, the flexible connection seal 2 and the sealing hoop 9 move up as a whole by 50 to 100 mm to form a sealed space. It should be noted that the material of the flexible connection seal 2 is a non-carbon-containing flexible material.

[0029] The cylindrical design of the flexible connection seal 2 enables the flexible connection seal 2 to provide uniform sealing pressure in multiple directions, thereby ensuring the stability and reliability of the sealing effect. At the same time, the cylindrical structure is also convenient for installation and disassembly, reducing the maintenance cost and working difficulty. In addition, the length of the flexible connection seal is greater than the distance between the upper end of the silo lifting platform 7 and the sealing hoop 9, ensuring that during operation, the flexible connection seal can completely cover and press the gap between the silo lifting platform and the sealing hoop to prevent material leakage or external impurities from entering. It is suitable for application scenarios with high requirements for sealing performance. In practical applications, parameters such as the material, thickness, and elasticity of the flexible connection seal 2 also need to be selected and adjusted according to specific application scenarios. For example, in high-temperature, high-pressure, or corrosive environments, materials with high temperature resistance and corrosion resistance need to be selected, and the thickness and elasticity of the seal need to be appropriately increased to ensure the stability and reliability of the sealing effect.

[0030] Embodiment 2

[0031] A feeding sealing device for a liquid crystal substrate glass furnace according to the present utility model, as Figure 2As shown in the figure, before use, the flexible connection seal 2 and the feeding port are tightly fastened by the sealing hoop 5. During use, the feeding tank 9 is moved to a predetermined position. The silo lifting platform 7 moves upward along with the hydraulic cylinder 10. Then, the lever 4 moves upward along with the air cylinder 3. During the upward movement of the lever 4, since the first connecting member and the second connecting member are fixedly connected to the lever 4 through the positioning nut 41 and the fastening nut 42, and the cage 1 is fixedly connected to the first connecting member, during the upward movement of the lever 4, the cage 1 moves upward together with the flexible connection seal 2 until the cage 1 reaches the lower end face of the bottom plate 8 of the feeding tank and stops. The sealing hoop 5 tightly fastens the lower edge of the flexible connection seal 2 to ensure that a closed and dust-free feeding space is formed between the feeding tank 9 and the feeding port. Feeding operation in this sealed space can avoid dust generation, purify the environment, reduce pollution and protect the health of operators.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: modifications or equivalent replacements can still be made to the specific embodiments of the present invention. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention shall be covered by the protection scope of the claims of the present invention.
