Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a pre-pressing device for hot-melt glass PVB interlayer. Background Technology

[0002] PVB laminated glass is a type of safety glass made by sandwiching a layer of PVB (polyvinyl butyral) interlayer between two panes of glass under high temperature and pressure. This type of glass offers good safety, sound insulation, UV protection, and some energy-saving benefits. Below are some of the main characteristics and applications of PVB laminated glass.

[0003] In traditional processing, hot-melt glass, a major type of decorative glass, involves high-temperature hot-melting of the original glass surface to achieve different textured decorative processes. This process results in an uneven surface. A PVB interlayer is then sandwiched between two pieces of hot-melt glass, requiring further heating and melting of the PVB interlayer. The two glass sheets are then pressed under high pressure to ensure a tight bond between the hot-melt PVB interlayer and the glass. However, this method often results in gas remaining within the PVB interlayer, leading to uneven bonding between the interlayer and the glass. To overcome these shortcomings, we provide a hot-melt pre-pressing device for processing PVB interlayers in hot-melt glass, achieving a more uniform and tighter bonding effect. Utility Model Content

After heating is completed, the second electric telescopic rod 11 drives the mounting plate 12 to move upward. At this time, the third electric telescopic rod 15 moves downward, so that the lower roller 17 is in contact with the upper end of the glass plate. The second moving block 14 drives the third electric telescopic rod 15 and the lower roller 17 to move outside the first guide rod 13, so that the roller 17 rolls on the glass plate and makes the glass plate fit even better.

The corner blocks 9 on the same side of the side plate 1 are symmetrically arranged. When the bearing plate 25 moves to the upper end of the semi-circular groove 10, the first movable block 7 moves in the movable groove 6. At the same time, the first electric telescopic rod 8 extends and retracts, driving the corner block 9 on one side to move, correcting the position of the glass plate at the upper end of the bearing plate 25 so that it is in the middle position. A semi-circular groove 10 is symmetrically provided in the middle of one side of the side plate 1. A second guide rod 19 is provided inside the semi-circular groove 10.

A second bearing 504 is located on the upper end of the second gear 503. The second bearing 504 is located at the lower end of the connecting plate 405. The second gear 503 meshes with the first gear 403. When the rotary motor 502 starts, it drives the upper second gear 503 to rotate. The second gear 503 drives the first gear 403 to rotate. The first gear 403 drives the lower screw 402 to move up and down in the mounting cylinder 401, and at the same time drives the upper connecting plate 405 to move up and down. Under the action of the first bearing 404 and the second bearing 504, the angle of the connecting plate 405 is kept from rotating. The connecting plate 405 drives the upper first heating plate 406 to move. The first heating plate 406 heats the support plate 25, thereby indirectly heating the glass.

[0026] Working principle: The glass plate is placed on the upper end of the support plate 25. Then, the third moving block 20 moves outside the second guide rod 19, moving it to the uppermost end of the semicircular groove 10. Simultaneously, the third bearing 26 and the action of the first counterweight 23 and the second counterweight 24 ensure that the support plate 25 remains horizontal. When the support plate 25 moves to the upper end of the semicircular groove 10, the first moving block 7 moves within the moving groove 6. Simultaneously, the first electric telescopic rod 8 extends and retracts, driving the corner block 9 on one side to move, correcting the position of the glass plate at the upper end of the support plate 25, placing it in the middle position. The second electric telescopic rod 11 pushes the lower mounting plate 12 downwards, driving the lower... The second heating plate 18 at the end heats the glass at the upper end of the support plate 25 and pressurizes it to close. At the same time, the pushing mechanism 4 is activated, driving the lifting mechanism 5 to heat the support plate 25, thereby indirectly heating the glass plate and making its PVB interlayer more adherent. After heating is completed, the second electric telescopic rod 11 drives the mounting plate 12 to move upward. At this time, the third electric telescopic rod 15 moves downward, so that the lower roller 17 is in contact with the upper end of the glass plate. The second moving block 14 drives the third electric telescopic rod 15 and the lower roller 17 to move outside the first guide rod 13, so that the roller 17 rolls on the glass plate and makes the glass plate more adherent.
