Description

Technical Field

[0001] This utility model relates to the field of glass production technology, specifically a high-temperature pre-pressing device for laminated glass production. Background Technology

[0002] The high-temperature pre-pressing device for laminated glass production is a specialized piece of equipment used in the manufacturing process of laminated glass. It utilizes the combined effects of a high-temperature environment and mechanical pressure to promote the initial bonding and formation of the glass and the interlayer film (such as PVB, EVA, etc.). Its core function is to apply uniform pressure and stable temperature to the laminated glass during the pre-pressing stage, ensuring that the melted interlayer film adheres tightly to the glass surface. Simultaneously, it treats any excess interlayer film at the edges, laying the foundation for the subsequent complete curing process.

[0003] Chinese patent CN216346086U discloses a high-temperature pre-pressing device for laminated glass production. The device uses a pushing mechanism to process the adhesive flowing out of the glass during the high-temperature pre-pressing process. The adhesive squeezed out of the laminated glass is processed by a scraping mechanism, so that the glass can be dried and used after the high-temperature pre-pressing is completed without further processing.

[0004] However, its adhesive scraping mechanism uses the positioning plate of the pushing mechanism for longitudinal positioning, without clamping the glass on both sides. During pre-pressing, uneven pressure may cause the glass to shift laterally, and the direction of adhesive overflow is uncontrollable. At the same time, the adhesive scraping mechanism adopts a fixed connection, and replacing the scraper or cleaning the adhesive requires disassembling complex parts, resulting in low maintenance efficiency.

[0021] 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.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figure 1 , Figure 2 and Figure 3 A high-temperature pre-pressing device for laminated glass production includes a high-temperature pre-pressing chamber cover 49, a hydraulic cylinder 41 disposed inside the high-temperature pre-pressing chamber cover 49, an upper support plate 42 disposed at the drive end of the hydraulic cylinder 41, laminated glass 44 placed below the upper support plate 42, a lower support plate 45 disposed at the lower end of the laminated glass 44, and a support platform 47 disposed at the lower end of the lower support plate 45. A glass clamping mechanism 43 is disposed at the upper end of the lower support plate 45, and the glass clamping mechanism 43 is located on both sides of the laminated glass 44. A groove is formed on the upper surface of the support platform 47, and an electric heater is installed inside the groove. A high-temperature pre-pressing chamber body 48 is fixedly connected to the lower end of the support platform 47. The high-temperature pre-pressing chamber body 48 is connected to the high-temperature pre-pressing chamber cover 49 to form a high-temperature pre-pressing chamber 4. A glue scraping component 46 is disposed inside the high-temperature pre-pressing chamber body 48.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1:

[0026] Please see Figure 3 and Figure 4 The adhesive scraping component 46 includes a support column 464 disposed inside the high-temperature pre-pressing chamber 48. A drive motor 461 is disposed on one side of the support column 464. A threaded rod 462 is fixedly installed at the output end of the drive motor 461. A connecting block 466 is threadedly installed on the outer side of the threaded rod 462. An adhesive scraping mechanism 468 is installed on one side of the connecting block 466. The adhesive scraping mechanism 468 is in close contact with one side of the laminated glass 44.

[0027] After the laminated glass 44 falls onto the upper end of the lower support plate 45, the glass clamping mechanism 43 is immediately activated to stabilize both sides of the laminated glass 44, ensuring that the laminated glass 44 does not shift during the pre-pressing process. The glue can only overflow towards the glue scraping component 46. The hydraulic cylinder 41 installed inside the high-temperature pre-pressing chamber cover 49 drives the upper support plate 42 to apply downward pressure, cooperating with the lower support plate 45 to fully bond the glue in the middle of the laminated glass 44, improving the strength and sealing of the glass and ensuring the pre-pressing effect. After the pre-pressing is completed, the drive motor 461 is started to drive the threaded rod 462 to rotate. The connecting block 466 moves along the threaded rod 462 with the glue scraping mechanism 468 to scrape off the overflow glue in time. The electric heater provides a heat source for the lower support plate 45, indirectly heating the laminated glass 44 at the upper end of the lower support plate 45. Combined with the pressure of the hydraulic cylinder 41, the pre-pressing effect of the laminated glass 44 is further improved.

[0028] The glass clamping mechanism 43 includes a fixed housing 431 disposed on the upper end of the lower support plate 45, an electric telescopic rod 433 disposed on the inner wall of the fixed housing 431, a sliding cylinder 432 disposed on the upper end of the fixed housing 431, and a clamping block 435 disposed on the driving end of the electric telescopic rod 433. The fixed housing 431 provides a stable mounting carrier for the electric telescopic rod 433. After being energized, the electric telescopic rod 433 can extend and retract axially. Through the extension and retraction action, it pushes the clamping block 435 closer to or further away from the laminated glass 44. The sliding cylinder 432 provides a guiding function for the glass transported into the high-temperature pre-compression chamber 4, thereby achieving stable transmission of the laminated glass 44, preventing displacement during the pre-compression process, and ensuring a uniform and reliable pre-compression effect.

[0029] The high-temperature pre-compression chamber 4 is equipped with conveyor belts A3 and B6 on both sides. Support legs 2 are installed at the lower ends of the high-temperature pre-compression chamber 4, conveyor belts A3 and B6, and support pads 1 are installed at the lower ends of the support legs 2. Material removal doors 5 are installed on the other two sides of the high-temperature pre-compression chamber 48, and these doors 5 pass through the high-temperature pre-compression chamber 48. Conveyor belts A3 and B6 are tightly connected to both sides of the high-temperature pre-compression chamber 48. Conveyor belt A3 first transports a piece of glass with adhesive into the high-temperature pre-compression chamber 48, and then conveyor belt B6 transports another piece of glass into the high-temperature pre-compression chamber 48 for pre-compression. The material removal doors 5 on both sides of the high-temperature pre-compression chamber 48 are closed during pre-compression and opened after pre-compression is completed, facilitating the removal of laminated glass 44 or maintenance of the adhesive scraping component 46 by the operator. The support legs 2 and support pads 1 ensure the overall stability of the device.

[0030] Specifically, the conveyor belt A3 transports the laminated glass 44 to be pre-compressed into the high-temperature pre-compressing chamber 48. At this time, the sliding cylinder 432 contacts the edge of the glass, providing guidance and ensuring that the glass is accurately positioned along a fixed path. The lower end of the laminated glass 44 rests on the lower support plate 45. After the electric telescopic rod 433 of the glass clamping mechanism 43 is energized, it extends and pushes the clamping block 435 to move to both sides of the laminated glass 44 until the clamping block 435 is tightly fitted with the edge of the glass, completing the clamping and fixing. The electric heater located in the groove of the support platform 47 heats up after being energized, and conducts the heat to the laminated glass 44 through the lower support plate 45, softening the interlayer adhesive. At the same time, high-temperature pre-compressing... The hydraulic cylinder 41 inside the cover 49 drives the upper support plate 42 to move downward, forming vertical pressure with the lower support plate 45, forcing the adhesive to bond tightly at high temperature, expelling internal air and eliminating air bubbles. After pre-pressing is completed, the drive motor 461 starts, driving the threaded rod 462 to rotate. The connecting block 466 moves along the threaded rod 462, and the adhesive scraping mechanism 468 on one side of it is close to the edge of the glass to scrape off the adhesive that overflowed during the pre-pressing process. Finally, the hydraulic cylinder 41 retracts, driving the upper support plate 42 to reset. The electric telescopic rod 433 retracts simultaneously to release the clamping block 435, and the material removal door 5 opens, thereby facilitating the removal of the pre-pressed laminated glass 44 and improving the pre-pressing efficiency of the laminated glass 44.

[0031] Example 2:

[0032] Please see Figure 4 and Figure 5The adhesive scraping mechanism 468 includes an adhesive collection cylinder 4682 disposed on one side of the connecting block 466, a scraper 4681 disposed on the upper end of the adhesive collection cylinder 4682, and triangular grooves 434 formed at both ends of the clamping block 435, with the scraper 4681 matching the triangular grooves 434. The scraper 4681 is directly positioned above the adhesive collection cylinder 4682, ensuring that the scraped adhesive falls directly into the adhesive collection cylinder 4682 for easy subsequent recycling. The triangular grooves 434 are formed at both ends where the clamping block 435 contacts the laminated glass 44. When the adhesive scraping mechanism 468 moves with the connecting block 466, the triangular blade of the scraper 4681 is precisely embedded in the triangular groove 434 and slides along the groove wall, thoroughly scraping away the adhesive residue remaining on the clamping block 435 and recycling it inside the adhesive collection cylinder 4682. This prevents the adhesive from contaminating the surface of the laminated glass 44 and affecting the accuracy of the clamping block 435 in the next clamping of the glass.

[0033] A guide rail 463 is provided on one side of the support column 464, and the guide rail 463 is located below the threaded rod 462. A T-shaped block is provided at the lower end of the connecting block 466, and the connecting block 466 is slidably connected to the T-slot on the guide rail 463 through the T-slot and the T-slot. The T-slot on the guide rail 463 and the T-slot cooperate with each other to ensure that the glue scraping mechanism 468 does not deviate when rotating with the threaded rod 462.

[0034] A mounting base 4683 is provided on one side of the scraper 4681. A rectangular hole is formed through the upper surface of the mounting base 4683. A fixing plate 467 is provided at the upper end of the connecting block 466. A circular hole is formed through the outer surface of the fixing plate 467. The fixing plate 467 and the rectangular hole are on the same vertical plane. A pin 465 is provided on the inner wall of the circular hole. The rectangular hole of the mounting base 4683 matches the fixing plate 467. The pin 465 passes through the circular hole of the fixing plate 467, forming a detachable connection. The scraping mechanism 468 can be removed simply by pulling out the pin 465.

[0035] Specifically, the T-shaped block at the lower end of the connecting block 466 engages with the T-shaped groove of the guide rail 463 to ensure that it moves linearly along the axial direction of the threaded rod 462. When the connecting block 466 moves, the scraper 4681 of the scraping mechanism 468 moves along with it. The blade of the scraper 4681 is triangular and can be embedded in the triangular groove 434, sliding along the groove wall to completely scrape off the adhesive residue remaining on the clamping block 435. The scraped adhesive falls along the inclined surface of the scraper 4681 into the adhesive collection cylinder 4682 below, completing the recycling and reuse of the adhesive. The guide rail 463 provides rigid support for the connecting block 466, effectively bearing the lateral force during scraping, preventing the connecting block 466 from shaking or shifting, and ensuring that the movement trajectory of the scraper 4681 is completely parallel to the edge of the glass. The scraping mechanism 468 is aligned with the fixing piece 467 of the connecting block 466 through the rectangular hole of the fixing seat 4683, and the pin 465 passes through the round hole to form a rigid connection. When it is necessary to replace the scraper 4681 or clean the adhesive collection cylinder 4682, the scraping mechanism 468 can be quickly disassembled by simply pulling out the pin 465 without the need for tools, which significantly improves maintenance efficiency.
