Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass production technology, and in particular to a glue scraping mechanism for a pre-rolling device for laminated glass. Background Technology
[0002] Laminated glass is a composite material made of glass or plexiglass and high-quality engineering plastics through special processing. It is usually a transparent material, typically consisting of a polycarbonate fiber layer sandwiched between ordinary glass layers. In the production process of laminated glass, a layer of PVB film is sandwiched between every two pieces of glass. After the glass and the film are bonded together, pressure is used to expel the air bubbles between the glass pieces, so that the two pieces of glass are initially bonded together.
[0003] A pre-rolling device for laminated glass, disclosed in CN116749628A, includes an outer frame with several conveyor rollers rotatably connected inside. Each conveyor roller has a glass holding box for loading laminated glass consisting of a lower glass layer, a PVB film, and an upper glass layer. When the glass holding box moves the laminated glass through the pre-rolling zone for roll pressing and air removal, it ensures that the lower and upper glass layers remain aligned, preventing misalignment during rolling and improving the pre-rolling effect. The device also includes a film cutting mechanism and a film feeding and receiving mechanism. The film cutting mechanism moves the film pressing frame down to press the glass holding box, cutting out the PVB film sheet in one operation. The PVB film sheet is positioned above the lower glass layer inside the glass holding box, eliminating the need for manual cutting with a blade, saving time and effort, and preventing safety hazards. However, during the high-temperature pre-pressing process, the adhesive sandwiched between the glass panes in these existing pre-rolling devices is constantly squeezed, causing some of it to leak out of the glass in multiple places. Since the glass is located in the pre-rolling device, it is difficult to deal with the leaked adhesive residue in time, requiring workers to clean and scrape it off later, which affects work efficiency. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the existing technology that it is difficult to deal with the residual glue in time, which requires workers to clean and scrape it off later, thus affecting work efficiency. The invention provides a scraping mechanism for a pre-rolling device for laminated glass. By having a scraper close to both sides of the laminated glass, the mechanism can scrape off the glue from both sides of the moving laminated glass after it has been pressurized and is being transported, thereby reducing the amount of glue scraping work and improving efficiency.
[0005] To achieve the above objectives, this utility model provides a glue-scraping mechanism for a pre-rolling device for laminated glass, comprising a first mounting frame and a second mounting frame. A scraper is connected inside both the first and second mounting frames. The scraper is used to scrape off the glue flowing from both sides of the glass. A glue-receiving box is provided below the scraper. An adjusting component is connected to the lower part of both the first and second mounting frames. The adjusting component includes a bidirectional lead screw, on which a first drive seat and a second drive seat are connected. The first drive seat is connected to the first mounting frame at its top, and the second drive seat is connected to the second mounting frame at its top. One end of the bidirectional lead screw is connected to a rotating disk. The bidirectional lead screw is detachably connected to the pre-rolling device via the mounting seats.
[0006] As a further description of the above technical solution: a limiting slide bar is provided on one side of the adjustment component, and a limiting slider is connected below both the first mounting frame and the second mounting frame, and the limiting slider is slidably connected to the limiting slide bar.
[0007] As a further description of the above technical solution: both the first mounting frame and the second mounting frame are provided with multiple mounting holes, and the scraper is detachably connected to the first mounting frame and the second mounting frame by bolts.
[0008] As a further description of the above technical solution: a sliding plate is provided below the glue receiving box, and a sliding groove is provided on both the first drive seat and the second drive seat, and the sliding groove is adapted to the sliding plate.
[0009] As a further description of the above technical solution: a handle is connected to one end of the glue receiving box.
[0010] As a further description of the above technical solution: the mounting base is provided with a bearing seat, and the bearing seat is connected to a bidirectional lead screw.
[0011] As a further description of the above technical solution: multiple scrapers are provided.
[0012] The above technical solution has the following advantages or beneficial effects:
[0013] This invention features glue collection boxes located below both the first and second mounting frames. These boxes collect the glue dripping during the pressurization process of the laminated glass. By placing the scrapers on the first and second mounting frames close to both sides of the laminated glass, the excess glue can be scraped off during transport after pressurization, collecting it into the collection boxes. This reduces the workload of subsequent glue scraping and improves efficiency. Furthermore, rotating the rotating disc drives a bidirectional lead screw, causing the first and second drive seats to move towards or away from each other. This adjusts the distance between the scrapers on the first and second mounting frames, facilitating glue scraping for laminated glass of different specifications. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] like Figure 1-4 As shown, this utility model provides a glue scraping mechanism for a pre-rolling device for laminated glass, including a first mounting frame 1 and a second mounting frame 2. A scraper 3 is connected inside both the first mounting frame 1 and the second mounting frame 2. The scraper 3 is used to scrape off the glue flowing from both sides of the glass. A glue receiving box 4 is provided below the scraper 3. Both the first mounting frame 1 and the second mounting frame 2 are connected to an adjusting component 5 at their lower ends. The adjusting component 5 includes a bidirectional lead screw 51, with a first drive seat 52 and a second drive seat 53 connected to the bidirectional lead screw 51. The first drive seat 52 is connected to the first mounting frame 1 at its top, and the second drive seat 53 is connected to the second mounting frame 2 at its top. One end of the bidirectional lead screw 51 is connected to a rotating disk 54. The bidirectional lead screw 51 is detachably connected to the pre-rolling device 6 via a mounting seat 55.
[0024] In the technical solution provided by this utility model, glue collection boxes 4 are provided below both the first mounting frame 1 and the second mounting frame 2. The glue collection boxes 4 can collect the glue dripping during the pressurization process of the laminated glass. By pressing the scrapers 3 on the first mounting frame 1 and the second mounting frame 2 tightly against both sides of the laminated glass, the sides of the moving laminated glass can be scraped off after pressurization and conveyed. The excess glue on both sides of the laminated glass is hung in the glue collection box 4 for collection, reducing the workload of subsequent glue scraping and improving efficiency. At the same time, by rotating the rotating disk 54, the bidirectional lead screw 51 can be rotated, which drives the first drive seat 52 and the second drive seat 53 to move towards or away from each other, thereby driving the first mounting frame 1 and the second mounting frame 2 to move towards or away from each other. The distance between the scrapers 3 on the first mounting frame 1 and the second mounting frame 2 can be adjusted to facilitate glue scraping for laminated glass of different specifications.
[0025] The scraper 3 is provided in multiple ways; multiple scrapers 3 are connected inside the first mounting frame 1 and the second mounting frame 2, which can enhance the scraping effect. Multiple scrapers 3 scrape the glue on both sides of the glass in turn.
[0026] like Figure 1 and Figure 2 As shown, specifically, a limiting slide bar 7 is provided on one side of the adjustment component 5, and a limiting slider 8 is connected to the bottom of both the first mounting frame 1 and the second mounting frame 2. The limiting slider 8 is slidably connected to the limiting slide bar 7. By sliding the limiting slider 8 on the limiting slide bar 7, the limiting slide bar 7 can limit the first mounting frame 1 and the second mounting frame 2, thereby enhancing the stability of the first mounting frame 1 and the second mounting frame 2 when they move.
[0027] like Figure 1 and Figure 2As shown, specifically, the first mounting frame 1 and the second mounting frame 2 are each provided with multiple mounting holes 9. The scraper 3 is detachably connected to the first mounting frame 1 and the second mounting frame 2 by bolts 10. The bolts 10 facilitate the installation and removal of the scraper 3, making it easy to replace the scraper 3. The multiple mounting holes 9 on the first mounting frame 1 and the second mounting frame 2 facilitate the installation of the scraper 3 in different locations, enhancing the applicability of the mechanism.
[0028] like Figure 1 and Figure 2 As shown, specifically, a sliding plate 11 is provided below the glue receiving box 4, and a sliding groove 12 is provided on both the first drive seat 52 and the second drive seat 53. The sliding groove 12 is adapted to the sliding plate 11. The sliding plate 11 provided below the glue receiving box 4 is adapted to the sliding groove 12 provided on both the first drive seat 52 and the second drive seat 53, which makes it convenient to remove the glue receiving box 4 from the first drive seat 52 and the second drive seat 53, and facilitates the cleaning and replacement of the glue receiving box 4 on the first drive seat 52 and the second drive seat 53.
[0029] The glue receiving box 4 is connected to a handle 13 at one end; the handle 13 makes it easy to pull out the glue receiving box 4 for cleaning.
[0030] like Figure 1 and Figure 2 As shown, specifically, a bearing seat 56 is provided on the mounting base 55, and the bearing seat 56 is connected to the bidirectional lead screw 51; the bearing seat 56 enhances the stability of the bidirectional lead screw 51 and the limiting slide bar 7.
[0031] Working principle: By setting glue collection boxes 4 under both the first mounting frame 1 and the second mounting frame 2, the glue dripping during the pressurization process of the laminated glass can be collected. By pressing the scrapers 3 on the first mounting frame 1 and the second mounting frame 2 against both sides of the laminated glass, the excess glue on both sides of the moving laminated glass can be scraped off during the conveying process after pressurization. The excess glue is collected in the glue collection boxes 4, reducing the workload of subsequent glue scraping and improving efficiency. At the same time, by rotating the rotating disk 54, the bidirectional lead screw 51 can be rotated, which drives the first drive seat 52 and the second drive seat 53 to move towards or away from each other, thereby driving the first mounting frame 1 and the second mounting frame 2 to move towards or away from each other. The distance between the scrapers 3 on the first mounting frame 1 and the second mounting frame 2 can be adjusted to facilitate glue scraping for laminated glass of different specifications.
