Description

Technical Field

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

[0002] In the production of laminated glass, the glass surface is cleaned, and then PVB soaked in adhesive is adhered between the two layers of glass. Then, the adhesive is poured between the two layers of glass through a reserved channel, and a vacuum is drawn at a low temperature (room temperature or moderate heating, such as 40-60℃) to avoid damage to the film material. Then, a vacuum pump is used to remove air.

[0003] In traditional equipment, the glass is placed directly on the workbench, which requires workers to move around the workbench frequently when applying PVB film. This is not only inefficient but also increases labor intensity. In addition, the close contact between the glass and the workbench makes it difficult to operate due to friction or adsorption when loading and unloading, which affects production efficiency.

[0004] To address this, we propose a cold vacuum sealing device for laminated glass. Utility Model Content

An air extraction pipe connector 4 is fixedly installed in the middle of the upper part of the front outer surface of the base box 1. The air extraction pipe of the vacuum pump 13 is connected to the air extraction pipe connector 4.

[0026] The upper end of the rotating shaft 15 passes through the middle of the upper end of the base box 1 and is fixedly connected to the middle of the lower outer surface of the processing table 5. Thrust bearings are provided between the rotating shaft 15, the base box 1, and the support frame 17, and the rotating shaft 15 is rotatably connected to the base box 1 and the support frame 17 through the thrust bearings. A coupling is provided between the rotating shaft 15 and the geared motor 16, and the lower outer surface of the rotating shaft 15 is fixedly connected to the upper outer surface of the output shaft of the geared motor 16 through the coupling. There are two sets of guide rails 6, support arms 7, rubber pads 8, fixing blocks 10, threaded holes 11, screws 12, and knobs 14. The two sets of guide rails 6 are fixedly installed on the front and rear sides of the upper outer surface of the processing table 5, and the two sets of fixing blocks 10 are fixedly installed on the upper end of the processing table 5. The middle of the left and right sides of the outer surface; the sliding groove 9 is opened on both sides of the lower outer surface of the support arm 7, and the support arm 7 is slidably connected to the outer wall of the guide rail 6 through the sliding groove 9. The rubber pad 8 is bonded to the upper outer surface of the support arm 7; the knob 14 is fixedly installed on the outer surface of one end of the screw 12, and one end of the screw 12 is connected to the middle of the outer surface of one side of the support arm 7.

[0027] It should be noted that this utility model is a cold vacuum sealing device for laminated glass. The loading structure 3 is configured such that, firstly, the distance between the two sets of support arms 7 is adjusted according to the width of the glass. Then, the knob 14 is rotated, causing the screw 12 to rotate. The screw 12 moves along the threaded hole 11, which in turn moves the support arms 7. The support arms 7 slide along the guide rail 6 via the sliding groove 9.

After placing a set of glass on the upper part of the carrier structure 3, the PVB soaked in glue is then adhered to the glass. The rotation of the geared motor 16 drives the rotating shaft 15 to rotate, which in turn drives the processing table 5 to rotate, thereby rotating the glass. This facilitates the adhesion of the PVB soaked in glue to the upper part of the glass around one circumference. Then, another layer of glass is covered, and the glue is injected through the reserved channel. Then, the external air extraction pipe is connected to the air extraction pipe connector 4, and the air is extracted between the glass by the operation of the vacuum pump 13.
