Description

Technical Field

[0001] This invention relates to the field of automatic glass coating machine technology, specifically, to an automatic glass coating machine. Background Technology

[0002] An automatic glass coating machine is a device specifically designed to automatically cover the surface of glass with a protective film (usually a plastic film). It is widely used in the production, processing, storage and transportation of glass, and can effectively protect the glass surface from external damage such as scratches, pollution, dust, and oil.

[0003] The existing laminating machine works as follows: first, the protective film is introduced from the storage roller into the pressure roller, then the glass on the worktable is transported into the pressure roller, and the protective film and glass are pressed together by heating the pressure roller.

[0004] While this method enables the coating process on glass, the following problems still exist: Since the protective film is rolled on the unloading roller, wrinkles may occur during transportation or processing. If the coating process continues, bubbles or wrinkles may appear on the protective film attached to the glass, affecting the coating effect. Summary of the Invention

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 2-9 As shown in the figure, this embodiment proposes an automatic glass coating machine, the structure of which includes a fixed frame 1.

[0035] In this embodiment, the first transport structure is mounted on the fixed frame 1 and is used to transport the glass 3. A storage roller 4 is rotatably mounted on the upper side of the fixed frame 1. A first pressing roller 5 and a second pressing roller 6 are rotatably mounted on the fixed frame 1 and are used to press the glass 3 with film. A cutting blade 761 is fixedly mounted on the fixed frame 1 and is used to cut the film-coated glass 3. The second transport structure is mounted on the fixed frame 1 and is used to transport the cutting blade 761. A pressing structure is mounted on the side of the fixed frame 1 near the cutting blade 761 and is used to press the glass 3 firmly. A first mounting member 9 is mounted on the fixed frame 1, and a first tensioning roller 911 and a second tensioning roller 921 are rotatably mounted on the first mounting member 9. A first adjustment structure is mounted on the first mounting member 9 and is used to adjust the angle between the first tensioning roller 911 and the second tensioning roller 921. A second adjustment structure is mounted on the fixed frame 1 and is used to control the first mounting member 9 to move away from or closer to the fixed frame 1.

[0036] The first adjustment structure in this embodiment includes a first adjustment screw 981, a first sliding groove 93, a second sliding groove 94 and a third sliding groove 95 disposed on the first mounting member 9, the third sliding groove 95 disposed between the first sliding groove 93 and the second sliding groove 94, and the third sliding groove 95 being perpendicular to both the first sliding groove 93 and the second sliding groove 94, in order to ensure that the first rotating shaft 91 and the second rotating shaft 92 will not slip or deviate. The first rotating shaft 91 and the second rotating shaft 92 are mounted on the first mounting part 9. The first tensioning roller 911 is rotatably connected to the first rotating shaft 91, and the second tensioning roller 921 is rotatably connected to the second rotating shaft 92. A connecting shaft 912 is rotatably connected between the first rotating shaft 91 and the second rotating shaft 92. The connecting shaft 912 is slidably connected to the third sliding groove 95. The end of the first rotating shaft 91 away from the second rotating shaft 92 is slidably connected to the first sliding groove 93. The end of the second rotating shaft 92 away from the first rotating shaft 91 is slidably connected to the second sliding groove 94. The first sliding rail 97 is fixedly mounted on the first mounting part 9. The sliding member 98 is slidably mounted in the first sliding rail 97 and is rotatably connected to the connecting shaft 912. The first adjusting screw 981 is rotatably mounted in the first sliding rail 97 and is threadedly connected to the sliding member 98. In this embodiment, the movement of the sliding member 98 is adjusted by the first adjusting screw 981. Since the rotational stroke of the first adjusting screw is much greater than the movement stroke of the sliding member 98, controlling the movement of the sliding member 98 by rotating the first adjusting screw is more stable and reliable. In this embodiment, the first tensioning wheel 75 and the second tensioning wheel 75 generate a stretching force to both sides when the glass film passes by, reducing wrinkles on the glass 3 and improving the quality of the coating on the glass 3.

[0037] The second adjustment structure in this embodiment includes a first telescopic member 96, a second sliding rail 12 fixed on the fixed frame 1, a first mounting member 9 slidably connected to the second sliding rail 12, a fixed end of the first telescopic member 96 fixedly connected to the fixed frame 1, and a telescopic end of the first telescopic member 96 fixedly connected to the first mounting member 9. The first telescopic member 96 used in this embodiment is preferably a hydraulic cylinder or a pneumatic cylinder. Since hydraulic cylinders or pneumatic cylinders are existing technologies, they will not be described in detail in this embodiment.

[0038] In existing laminating machines, the glass 3 raw materials are fed into the machine separately, with gaps between them. During lamination, when the pressure roller presses into these gaps, the glass film, lacking support from below, begins to sink. When the glass 3 re-enters the pressure roller, it rises again due to the support from below. This up-and-down movement causes deformation, potentially leading to wrinkles and air bubbles, thus reducing lamination quality. Therefore, this embodiment uses a first telescopic member 96 to control the tensioning of the first tensioning roller 911 and the second tensioning roller 921. When the cutting blade 761 cuts the glass film, the first telescopic member 96 prevents the first and second tensioning rollers 911 and 921 from tensioning the glass film, thus preventing displacement and deformation during cutting. When the first and second tensioning rollers 911 and 921 tension the glass film, the lamination quality is improved.

[0039] In this embodiment, the first transport structure includes a first conveyor belt 2, which is rotatably connected to a fixed frame 1. Several second mounting members 21 are fixedly mounted on the first conveyor belt 2. The cross-section of each second mounting member 21 is U-shaped and is used to mount a first limiting member 22. The first limiting member 22 is threaded onto the second mounting members 21 and is used to limit the glass 3 in the X-axis direction. Since the width of the glass 3 varies when processing different types of glass 3, this design expands the applicability of the coating machine for processing glass 3. In this embodiment, a plurality of fourth sliding grooves 113 are provided on the fixed frame 1, and each fourth sliding groove 113 is provided on both sides of the first conveyor belt 2. The second limiting member 11 is provided on the fixed frame 1, and the locking bolt 112 is provided on the second limiting member 11. The locking bolt 112 is slidably connected to the fourth sliding groove 113. The second limiting member 11 is threadedly connected to the fixed frame 1 through the locking bolt 112. A plurality of limiting wheels 111 are rotatably provided on the second limiting member 11 to ensure that the glass 3 will not slip or deviate. Moreover, since the limiting wheel 111 is in rolling connection with the glass 3, the frictional wear of the limiting wheel 111 on the glass 3 can be reduced.

[0040] In this embodiment, the support beam 13 is fixedly mounted on the fixed frame 1 and is used to install the first sliding rod 51 and the second sliding rod 52. The first sliding rod 51 and the second sliding rod 52 are slidably mounted on both sides of the support beam 13. The first mounting plate 55 and the second mounting plate 56 are rotatably mounted on both sides of the first pressing roller 5. The first connecting rod 511 is fixedly mounted between the first sliding rod 51 and the first mounting plate 55. The second connecting rod 521 is fixedly mounted between the second sliding rod 52 and the second mounting plate 56. The first limiting spring 512 is sleeved on the first connecting rod 511, and its two ends are fixedly connected to the first sliding rod 51 and the first mounting plate 55, respectively. The second limiting spring 522 is sleeved on the second connecting rod 521, and its two ends are fixedly connected to the second sliding rod 52 and the second mounting plate 56, respectively. In this embodiment, the first limiting spring 512 and the second limiting spring 522 ensure that the first pressing roller 5 always abuts against the glass 3. Even if the thickness of the glass 3 changes, the first pressing roller 5 can be moved by the first limiting spring 512 and the second limiting spring 522 to reduce collision damage to the glass 3.

[0041] In this embodiment, the connecting plate is located at the end of the first sliding rod 51 away from the first mounting plate 55. The other end of the connecting plate is fixedly connected to the second sliding rod 52. The second telescopic member 53 is mounted on the fixed frame 1. The fixed end of the second telescopic member 53 is fixedly connected to the fixed frame 1, and the telescopic end of the second telescopic member 53 abuts against the first connecting plate 54. The structure of the second pressing roller 6 is the same as that of the first pressing roller 5. In this embodiment, the second telescopic member 53 is preferably a hydraulic cylinder or a pneumatic cylinder. Hydraulic cylinders or pneumatic cylinders are existing technologies and will not be described in detail in this embodiment. When the thickness of the processed glass 3 changes, this embodiment can set a thickness tester on the fixed frame 1 to test the thickness of the glass 3. Based on this, the second telescopic member 53 is used to control the pressing height of the first pressing roller 5 and the second pressing roller 6 on the glass 3.

[0042] In this embodiment, the second transport structure includes a second conveyor belt 76, a die-cutting plate 7 fixedly mounted on a fixed frame 1, and a third sliding rail 78 mounted on the die-cutting plate 7 to prevent the cutting blade 761 from shifting. The cutting blade 761 is slidably connected to the third sliding rail 78, the second conveyor belt 76 is rotatably connected to the die-cutting plate 7, and the second conveyor belt 76 is fixedly connected to the cutting blade 761. In this embodiment, the movement of the cutting blade 761 is controlled by the second conveyor belt 76 to perform the cutting operation on the protective film of the glass 3, replacing manual cutting, making the laminating machine operation more automated and intelligent, and more convenient to use.

[0043] In this embodiment, the first rotating wheel 73 and the second rotating wheel 74 are rotatably mounted on the die-cutting plate 7. The fifth sliding groove 77 is mounted on the die-cutting plate 7, and the tensioning wheel 75 is slidably mounted within the fifth sliding groove 77. The second conveyor belt 76 is simultaneously connected to the first rotating wheel 73, the second rotating wheel 74, and the tensioning wheel 75. The fourth sliding rail 71 is mounted on the die-cutting plate 7, and the sliding member 98 is slidably mounted on the fourth sliding rail 71. The tensioning wheel 75 is rotatably connected to the sliding member 98. The second adjusting screw 72 is rotatably mounted on the fourth sliding rail 71 and is threadedly connected to the sliding member 98. In this embodiment, the movement of the sliding member 98 is controlled by rotating the second adjusting screw 72. Because of the threaded connection between the second adjusting screw 72 and the sliding member 98, when the sliding member 98 moves to the appropriate position, the sliding member 98 can self-lock relative to the fourth sliding rail 71, and the position of the tensioning wheel 75 can be positioned. The tensioning wheel 75 may become loose during prolonged operation of the cutting blade 761. In this embodiment, the second conveyor belt 76 can be restored to a tensioned state by using the second adjusting screw 72.

[0044] In this embodiment, several pressing feet 8 are slidably mounted on the fixed frame 1, and pressing wheels 84 are rotatably mounted on the side of each pressing foot 8 near the worktable. A third limiting spring 81 is sleeved on the pressing foot 8, and both sides of the third limiting spring 81 are fixedly connected to the fixed frame 1 and the pressing foot 8, respectively. In this embodiment, the pressing feet 8 press and position the glass 3, so that when the glass 3 is die-cut by the cutting blade 761, the protective film of the glass 3 will not slip or deviate. Under the action of the third limiting spring 81, even if the thickness of the processed glass 3 changes, the third limiting spring 81 will move the pressing feet 8 upward, reducing collision damage to the glass 3. The third limiting spring 81 also ensures that the pressing feet 8 are always in contact with the glass 3, so that the glass film will not deviate during cutting.

[0045] In this embodiment, the second connecting plate 82 is disposed on the top of the fixed frame 1. The ends of each pressing foot 8 furthest from the pressing wheel 84 are fixedly connected to the second connecting plate 82. The third telescopic member 83 is disposed on the fixed frame 1, with its fixed end fixedly connected to the fixed frame 1 and its telescopic end abutting against the second connecting plate 82. This embodiment allows for control of pressing glass 3 of different thicknesses via the third telescopic member 83, facilitating cutting by the cutting blade 761 and broadening its applicability.

[0046] The working process of this embodiment is as follows: First, one end of the protective film is placed on the storage roller 4, and the other end of the protective film is passed through the first tension roller 911, the second tension roller 921, the first pressing roller 5, and the second pressing roller 6. Then, the glass 3 is placed on the first conveyor belt 2. The second telescopic rod and the third telescopic rod are adjusted according to the thickness of the glass 3 so that the first pressing roller 5 and the second pressing roller 6 are pressed tightly against the glass 3. Then, the protective film is tightened by extending the first telescopic member 96 so that the glass 3 is successfully coated with the protective film. When the glass 3 is transported close to the cutting knife 761, the first telescopic member 96 is retracted, and the cutting knife 761 is controlled by the second conveyor belt 76 to cut the glass 3, thus completing the coating process.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
