[0002] A bubble bag is a transparent soft packaging material, which has a buffering and protecting function and is commonly used for the buffering packaging of electronic products and the logistics transportation protection of products such as ceramics and glass. The bubble bag is mainly processed from a high-pressure polyethylene bubble film. During the forming stage of the bubble film, its surface has a certain temperature to make the two layers of film composite. However, the surface temperature of the bubble film cannot be too high, otherwise the bubble film will stick to the forming roller or the pressure roller. Therefore, the traditional bubble film forming device cools the bubble film by cooling the pressure roller. Since the traditional forming device only takes cooling measures for the pressure roller and does not take cooling measures for the forming roller, the temperature difference between the bubble film layers is very large, the composite effect is not ideal, and the quality of the bubble film is affected.

The water in the seven cooling rollers 9 converges in the flow dividing pipe 11 on the left and finally returns to the water tank 7, so as to form circulating water in the seven cooling rollers 9 to continuously cool the cooling rollers 9.

[0027] As Figure 1 shown, a forming roller 2, a pressing roller 3 and a guiding roller 4 are rotatably installed on the base 1. The forming roller 2 is located between the pressing roller 3 and the guiding roller 4. A gap is left between the forming roller 2 and the pressing roller 3. The guiding roller 4 is located in front of the forming roller 2 and is about 30 cm - 50 cm away from the forming roller 2. A driving mechanism is provided on the side of the base 1 for driving the rotation of the forming roller 2 and the pressing roller 3. A number of regularly distributed semi-circular holes are provided on the arc surface of the forming roller 2. A pipeline is provided inside the forming roller 2 to connect these semi-circular holes, and the main pipe of the pipeline is connected to a vacuum pump. The vacuum pump suction can form a negative pressure in the semi-circular holes, so as to suck out the air bubbles from the bubble film. A circulating pipeline is provided inside the pressing roller 3, and circulating water is passed through the pipeline for cooling the pressing roller 3. The seven cooling rollers 9 are all parallel to the forming roller 2, and the arc surfaces of the seven cooling rollers 9 are all in contact with the arc surface of the forming roller 2. The forming roller 2 can conduct heat to the seven cooling rollers 9, so as to cool the forming roller 2. An extrusion device is provided above the base 1.

[0029] The working principle and usage process of the present utility model are as follows:

[0030] When the bubble bag and bubble film forming device is in use, the water pump 8 is started. The water pump 8 pumps the water in the water tank 7 into the right shunt pipe 11. Then the water enters the seven cooling rollers 9 through the right shunt pipe 11. The water in the seven cooling rollers 9 converges in the left shunt pipe 11 after coming out and finally returns to the water tank 7. When the device is working, the heat of the forming roller 2 will be conducted to the cooling roller 9, and then the heat will be taken away with the circulating water in the cooling roller 9, so as to achieve the effect of cooling the forming roller 2. The cooling measures arranged in the pressure roller 3 will also continuously cool the pressure roller 3. After the extrusion equipment extrudes the film, the bubble film is formed through the cooperation of the forming roller 2 and the pressure roller 3. During this period, the forming roller 2 and the pressure roller 3 will cool the bubble film, and part of the heat of the bubble film will be conducted to the forming roller 2 and the pressure roller 3, so as to reduce the temperature of the bubble film and prevent the temperature of the bubble film from being too high.
