Technical Field
[0001] This utility model relates to the field of glass drying technology, and in particular to a drying device for the production of low-emissivity coated heat-insulating glass. Background Technology
[0002] In the production process of low-emissivity coated heat-insulating glass, the drying process after coating has extremely high requirements for the uniformity of the glass surface, thermal efficiency and cleanliness. Therefore, a drying device for the production of low-emissivity coated heat-insulating glass is needed.
[0003] Traditional drying devices often use fixed hot air nozzles to blow on the glass surface. However, there are gaps between the fixed nozzles, and the areas between the gaps cannot be dried, resulting in uneven drying of the glass. In addition, dust in the air will adhere to the glass surface with the hot air during the drying process, causing impurities and defects in the glass. To solve the above problems, this application proposes a drying device for the production of low-emissivity coated heat-insulating glass. Utility Model Content

The device utilizes a conveyor belt to transport the glass, and a reciprocating screw to move the nozzles, ensuring uniform drying of the glass surface. A dustproof net filters airborne dust, and a combination of brushes and brush plates cleans the net, ensuring unobstructed airflow.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figures 1-4A drying device for producing low-emissivity coated heat-insulating glass includes a frame 1, a power motor 2 fixedly connected to the side wall of the frame 1, two transmission rods 3 rotatably connected to the frame 1, the output end of the power motor 2 being fixedly connected to the transmission rod 3 on the left side, and a transmission mechanism being provided between the two transmission rods 3, through which the low-emissivity coated heat-insulating glass body 7 can be conveyed and transmitted.
[0025] The transmission mechanism includes multiple conveying rollers 4 fixedly connected to the outer wall of each transmission rod 3. Each pair of conveying rollers 4 is fitted with a conveyor belt 5. Multiple conveyor belts 5 are used to hold the low-emissivity coated heat-insulating glass body 7. The outer walls of two transmission rods 3 are fitted with a first pulley belt 6. The outer wall of each transmission rod 3 is fixedly connected to a first pulley. The first pulley belt 6 is fitted on the outer walls of the two first pulleys. The low-emissivity coated heat-insulating glass body 7 can be conveyed by multiple conveyor belts 5 to dry its upper surface. The surface of the glass is coated with a bottom oxide, metallic silver, intermediate oxide and top oxide in sequence. Through layer sputtering and superposition, a balance between high light transmittance and low emissivity is achieved.
[0026] A servo motor 8 is fixedly connected to the side wall of the frame 1. Two reciprocating screws 9 are rotatably connected to the frame 1. The output end of the servo motor 8 is fixedly connected to the upper reciprocating screw 9. A second pulley is fixedly connected to the outer wall of each reciprocating screw 9. The outer walls of the two second pulleys are fitted with a second pulley belt 10, which can drive the two reciprocating screws 9 synchronously. This enables the upper nozzle 14 to spray hot air and the lower nozzle 14 to draw air. The two nozzles 14 form convection, which can absorb some of the sprayed hot air, resulting in good air heating and excellent glass drying effect. The outer walls of the two reciprocating screws 9 are fitted with moving blocks 11. Two sliding rods 12 are fixedly connected to the inner wall of the frame 1. The two sliding rods 12 pass through the corresponding moving blocks 11 and are slidably connected to them. Hollow plates 13 are fixedly connected to the opposite ends of the two moving blocks 11. Multiple nozzles 14 are installed on the opposite ends of the two hollow plates 13. The cooperation of the upper and lower sets of nozzles 14 results in excellent glass drying effect.
[0027] A dust removal mechanism is provided on the frame 1. The dust removal mechanism includes a dust collection box 15 fixedly connected to the top of the frame 1. A dustproof net 18 is fixedly connected to the inner wall of the dust collection box 15 to filter dust in the air. An air supply pipe 16 is fixedly connected to the side wall of the dust collection box 15 and is fixedly connected to the hollow plate 13 on the lower side. The air supply pipe 16 is a telescopic flexible hose and passes through the frame 1. A heat exchange mechanism 17 is provided between the dust collection box 15 and the upper hollow plate 13. The heat exchange mechanism 17 includes a first connecting pipe. The electric hot air blower is located on the top of the frame 1 and is fixedly connected to it. The air inlet and outlet of the electric hot air blower are fixedly connected to the first and second connecting pipes, respectively. The first and second connecting pipes are flexible hoses. The first connecting pipe is fixedly connected to the dust collection box 15, and the second connecting pipe is fixedly connected to the upper hollow plate 13. The electric hot air blower can heat the air into hot air, draw the purified air in the dust collection box 15 and finally inject it into the upper hollow plate 13 for discharge, thus drying the glass.
[0028] The dust collection box 15 is equipped with a brush plate 19, and multiple brushes are provided on the top of the brush plate 19. The multiple brushes are all set to abut against the bottom of the dustproof net 18. A limit rod 20 is fixedly connected to the inner wall of the dust collection box 15. The limit rod 20 passes through the brush plate 19 and is slidably connected to it. A T-shaped rod 21 is fixedly connected to the side wall of the brush plate 19. The T-shaped rod 21 passes through the dust collection box 15 and is slidably connected to it. The dustproof net 18 can be cleaned by moving the brush plate 19 to prevent it from becoming blocked.
[0029] In this invention, the power motor 2 is started, and its output drives the left transmission rod 3, the first pulley belt 6, and the right transmission rod 3 to perform synchronous transmission. The two transmission rods 3 drive multiple conveyor rollers 4 and conveyor belts 5 to perform synchronous transmission, thus conveying the low-emissivity coated heat-resistant glass body 7. The servo motor 8 and the electric hot air blower are started. The electric hot air blower draws air out of the dust collection box 15 to create a negative pressure, heats the air, and injects it into the upper hollow plate 13. Finally, multiple nozzles 14 on the upper side spray out hot air to dry the upper surface of the low-emissivity coated heat-resistant glass body 7. Meanwhile, the negative pressure in the dust collection box 15 draws air from the frame 1 through multiple nozzles 14 on the lower side and injects it into the lower hollow plate 13. The air is then transported into the dust collection box 15 via the air supply pipe 16. The dustproof net 18 can remove dust from the air, ensuring air cleanliness and reducing the possibility of dust adhering to the surface of the low-emissivity coated heat-insulating glass body 7. The output of the servo motor 8 drives the upper reciprocating screw 9, the second pulley belt 10, and the lower reciprocating screw 9 to rotate synchronously. The rotation of the two reciprocating screws 9 drives the moving block 11, the hollow plate 13, and multiple nozzles 14 to move, and the distance between the movements is greater than the distance between the two nozzles 14. This allows the hot air to dry the upper surface of the low-emissivity coated heat-insulating glass body 7 evenly, resulting in excellent drying effect. The operator can periodically hold the T-shaped rod 21 and rotate it to move the brush plate 19 and multiple brushes, which can clean the bottom of the dustproof net 18, prevent the dustproof net 18 from becoming blocked, and ensure smooth airflow.
