Description

Technical Field

[0001] This utility model relates to the field of glass production technology, specifically to a coating device for laminated glass production. Background Technology

[0002] Laminated glass is a composite glass made by bonding two or more pieces of glass with one or more layers of organic polymer interlayer between them under high temperature and pressure. Its core characteristic is high safety, as the fragments are held together by the interlayer after breakage, preventing them from flying and injuring people. It also has good sound insulation and heat insulation effects, and can block some ultraviolet rays to protect indoor items. Commonly used interlayers include PVB (the most widely used and with good weather resistance), EVA (low cost), and SGP (high strength). It is widely used in building curtain walls, automobile windshields, and aircraft windows, balancing safety and function, and is a high-quality glass material that combines protection and practicality.

[0003] Currently, the production process for laminated glass is divided into dry processing and wet processing. In wet processing, an applicator is needed to apply adhesive to the surface of the glass. During the applicator application, a roller conveyor belt is used to transport the glass. However, during the transport, the glass is prone to displacement due to vibration and other factors, which affects the adhesive application effect of the subsequent applicator and thus affects the production effect of laminated glass, which is not conducive to the production of laminated glass.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a new technical solution: a coating device for laminated glass production, including a conveying component 1, a mounting frame 2 fixedly installed on the upper surface of the conveying component 1, a coating component 3 provided at the lower end of the mounting frame 2, and two mounting plates 4 fixedly installed at both the front and rear ends of the upper surface of the conveying component 1. An auxiliary limiting mechanism is provided on the conveying assembly 1. The auxiliary limiting mechanism includes two first limiting plates 5 and two second limiting plates 6. The two first limiting plates 5 are slidably mounted on the upper surface of the conveying assembly 1. Electric push rods 7 are fixedly mounted on the distant surfaces of the two front mounting plates 4 and the two rear mounting plates 4. The near ends of the four electric push rods 7 pass through the near ends of the four front and rear mounting plates 4. The four electric push rods 7 are fixedly connected to the two first limiting plates 5 respectively. Screws 8 are threadedly mounted on the lower surface of the two first limiting plates 5. The upper ends of the two screws 8 are threaded through the upper ends of the two first limiting plates 5 respectively. The two second limiting plates 6 are rotatably mounted on the upper ends of the two screws 8 respectively.

[0016] Furthermore, the auxiliary limiting mechanism also includes four circular holes 9. The upper surfaces of the two first limiting plates 5 are provided with circular rods 10 at both ends. The four circular holes 9 are slidably inserted into the four circular rods 10 respectively, and the four circular holes 9 are fixedly connected to the two second limiting plates 6 respectively.

[0017] Furthermore, the first limiting plate 5 and the vertically adjustable second limiting plate 6 achieve full height coverage and limiting of the glass in the front and rear directions, adapting to glass of different thicknesses, avoiding glass displacement that could cause the coating roller to be misaligned, ensuring coating accuracy, and improving the production quality and efficiency of laminated glass.

[0018] Furthermore, each of the two second limiting plates 6 has a convex circular groove 11 inside, and a convex circular rod 12 is rotatably installed inside each of the two convex circular grooves 11. The two convex circular rods 12 are respectively fixedly connected to the two screws 8.

[0019] Furthermore, mounting grooves 13 are provided on the adjacent surfaces of the two first limiting plates 5 and the adjacent surfaces of the two second limiting plates 6, and multiple rollers 14 are rotatably installed inside the four mounting grooves 13.

[0020] Furthermore, cylinders 15 are fixedly installed on the upper surface of the mounting bracket 2, with the lower end of the cylinders 15 extending through to the bottom of the mounting bracket 2, and the cylinders 15 are fixedly connected to the coating component 3.

[0021] Furthermore, a dispensing box 16 is fixedly installed on the upper inner wall of the application component 3.

[0022] Furthermore, when using this device, the glass to be processed is placed on the conveying assembly 1. After starting, the conveying assembly moves the glass towards the coating assembly 3. According to the glass size, the electric push rods 7 on the front and rear sides are controlled to extend and retract, pushing the two first limiting plates 5 to slide back and forth and adjust them to be aligned with the front and rear sides of the glass, initially limiting the front and rear displacement of the glass. If the glass thickness is large, the two screws 8 are rotated. Since the screws 8 are threadedly connected to the first limiting plates 5 and the upper end is rotatably connected to the second limiting plate 6 through the convex round rod 12, when the screws 8 rotate, they will drive the second limiting plate 6 to slide up and down along the round rod 10, so that the second limiting plate 6 is aligned with the upper edge of the glass, realizing comprehensive limiting of glass of different heights. When the glass is conveyed to the bottom of the coating assembly 3, the cylinder 15 pushes the coating assembly 3 down, so that the coating roller contacts the glass surface. The glue feeding device supplies glue to the coating roller through the glue drip box 16, and the drive motor drives the coating roller to rotate, completing the uniform glue application during the glass movement. The rollers 14 on both sides of the glass rotate with the glass movement, reducing the frictional resistance during limiting and avoiding scratching the glass surface.

[0023] Structural Description: Conveying Component 1: As the foundation of the device, it supports and conveys the glass, providing a stable moving path for the adhesive coating.

They are fixed at the front and rear ends of the conveying component 1, support the electric push rod 7, provide a stable mounting point for the electric push rod 7, and enable the electric push rod 7 to stably push the first limit plate 5 to move. First limiting plate 5: There are two in total. They slide back and forth on the conveying component 1. The spacing is adjusted by the electric push rod 7 to limit the lower part of the glass in the front and back direction and prevent the glass from deviating during conveying.

The first limiting plate 5 is slid by telescopic drive to adjust the limiting distance and adapt to glass of different widths. Screw 8: There are two screws in total. The screw thread passes through the first limiting plate 5 and is connected to the second limiting plate 6 at the upper end. When rotated, it drives the second limiting plate 6 to move up and down, so as to adjust the height of the second limiting plate 6.
