[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Refer to Figure 1-2 , a bubble removal device for laminated glass, including a bracket 1, an input conveyor belt 2, a bubble removal chamber 3, and an output conveyor belt 4 sequentially arranged on the bracket 1. The bracket 1 is used as the main support and can be made of a strong steel structure or an aluminum alloy frame to ensure the stability and load-bearing capacity of the overall device. Secondly, adjustable feet can be equipped at the bottom of the bracket 1 to adapt to the flatness of different floors; the input conveyor belt 2 and the output conveyor belt 4 are used to cooperate with the bubble removal chamber 3 to be responsible for feeding the laminated glass to be processed into the bubble removal chamber 3 and sending out the processed laminated glass. The surfaces of these two conveyor belts are made of anti-slip and wear-resistant materials to ensure the smoothness and safety of the laminated glass during transmission. At the same time, the speeds of these two conveyor belts are adjustable to adapt to different production requirements; the bubble removal chamber 3 is used for de-bubbling the laminated glass. Specifically:

[0023] To facilitate the entry and exit of laminated glass, openings for the entry and exit of laminated glass into and out of the bubble removal box 3 are provided on both sides of the bubble removal box 3. Lift-type sealing doors 5 for controlling the opening and closing of the openings are installed on the bubble removal box 3 at the openings. The lift-type sealing door 5 includes a door body 13 and a first driving cylinder 14 for driving the door body 13 to move up and down. Slide rails 15 cooperating with the door body 13 are also provided on the bubble removal box 3 on both sides of the opening, facilitating driving the door body 13 to move up and down along the slide rails 15 through the first driving cylinder 14 to achieve the rapid opening and closing and sealing of the opening. A sealing strip is equipped at the door edge of the door body 13 to ensure the airtightness inside and outside the opening;

[0024] A horizontally arranged intermediate conveyor belt 6 is installed at the lower part inside the bubble removal box 3, which is used to convey the laminated glass entering the bubble removal box 3 from one side of the bubble removal box 3 to the other side. The speed of the intermediate conveyor belt 6 is adjustable and can operate synchronously or asynchronously with the input and output conveyor belts 4 to adapt to different processing procedures;

[0025] A steam injection pipe 7 for heating the laminated glass is installed at the upper part inside the bubble removal box 3 near the input conveyor belt 2. The steam injection pipe 7 is used to inject steam onto the laminated glass so that the steam can effectively cover and heat the surface of the laminated glass to promote the discharge of bubbles. The temperature and injection volume of the injected steam can be adjusted as needed. Preferably, the steam injection pipe 7 is externally connected to a steam supply pipe, and a number of steam nozzles 8 are also installed on the steam injection pipe 7. The injection direction of the steam nozzles 8 is inclined downward;

[0026] A roller 9 is installed inside the bubble removal box 3 above the middle of the intermediate conveyor belt 6. The roller 9 is installed inside the bubble removal box 3 through a lifting drive device. The roller 9 is used to roll-press the heated laminated glass to further promote the discharge of bubbles. A rolling gap cooperating with the laminated glass is left between the roller 9 and the intermediate conveyor belt 6. The lifting drive device is used to drive the roller 9 to move up and down to adjust the size of the rolling gap to facilitate meeting the extrusion requirements of laminated glass of different specifications; Preferably, the lifting drive device is installed at the top inside the bubble removal box 3, and the roller 9 is connected to the drive end of the lifting drive device through a number of buffer springs 10. The buffer springs 10 play a role in shock absorption and buffering, enabling the roller 9 to closely contact the surface of the laminated glass and apply a certain pressure, and also protecting the laminated glass from damage; The lifting drive device 11 is a second driving cylinder, and the second driving cylinder is installed upside down inside the bubble removal box 3, and the roller 9 is installed at the end of the piston rod of the second driving cylinder;

[0027] At the top of the bubble removal box 3 near one side of the output conveyor belt 4, a vacuum pump 12 is also installed. The vacuum pump 12 is started during the processing to pump out the air inside the box, creating a negative pressure environment. This helps to accelerate the discharge of bubbles and the drying process of the glass surface.

[0028] During actual use, the bubble removal box 3 is generally in a cuboid shape, which is convenient for installation and maintenance. At the same time, the box body of the bubble removal box 3 is made of stainless steel or corrosion-resistant materials, with a smooth interior and no dead corners, making it easy to clean. A transparent observation window is also provided on the bubble removal box 3, facilitating the operator to observe the internal situation of the bubble removal box 3 from the outside.

[0029] The present utility model aims to provide a bubble removal device for laminated glass, and its specific working process is as follows:

[0030] Workers or automated equipment place the laminated glass to be processed on the input conveyor belt 2 and ensure that the laminated glass is stably placed without slipping or tilting.

[0031] The input conveyor belt 2 slowly conveys the laminated glass into the bubble removal box 3. During the conveying process, the glass should move smoothly to avoid collision or vibration.

[0032] When the laminated glass enters the bubble removal box 3, the lifting and sealing door 5 closes, and the steam injection pipeline 7 starts to work. High-temperature steam is sprayed onto the glass surface through multiple steam nozzles 8. The temperature and injection volume of the steam are adjusted according to the material, thickness, and bubble situation of the laminated glass. The heating effect of the steam helps to soften the adhesive between the glass and the film, promoting the preliminary discharge of bubbles.

[0033] After the laminated glass passes through the steam heating area, the roller 9 slowly descends under the drive of the lifting cylinder until it contacts the glass surface and applies a certain pressure. This pressure should be appropriate, sufficient to discharge bubbles while avoiding damage to the glass.

[0034] The laminated glass continues to move with the intermediate conveyor belt, driving the roller 9 to roll over the surface of the laminated glass. During the rolling process, the combined action of the friction between the roller 9 and the laminated glass and the pressure applied by the roller 9 further promotes the discharge of bubbles.

[0035] Secondly, during or after the rolling to remove bubbles, the vacuum pump 12 starts to work, pumping out the air inside the bubble removal box 3 to create a negative pressure environment. The vacuum pumping helps to accelerate the discharge of bubbles.

[0036] The vacuum pump 12 continues to work for a period of time to ensure that a sufficient negative pressure state is maintained inside the bubble removal box 3 to thoroughly discharge the bubbles.

[0037] After the processing is completed, the lifting and sealing door 5 automatically opens, and the intermediate conveyor belt 6 sends the processed laminated glass out of the bubble removal box 3 and moves it onto the output conveyor belt 4;

[0038] Workers remove the processed laminated glass from the output conveyor belt 4 and perform subsequent quality inspections and packaging, etc.
