Description

Technical Field

[0001] The utility model relates to the technical field of glue coating devices, in particular to a glue coating device for the inner wall of a protective film. Background Art

[0002] The protective film inner wall gluing device is a device specially used to apply glue on the inner wall of the protective film. It is mainly composed of a gluing roller, a pressure roller, a drive motor and other parts. The gluing roller is located in the glue groove. When it rotates, the glue adheres to the surface and then applies the glue to one surface of the protective film. At the same time, the pressure roller is located above the gluing roller and cooperates with the gluing roller to complete the gluing process of the protective film. In addition, some equipment also drives the third roller to rotate through the drive motor to perform the gluing operation.

[0003] Currently, the existing protective film inner wall gluing device mainly uses a gluing roller and a pressure roller to apply glue. This equipment can effectively improve production efficiency and product quality. However, if the gap between the gluing roller and the pressure roller is not adjusted properly, it may cause uneven gluing, which in turn causes the protective film to shift when put into use, making it difficult for the protective film to provide a protective effect on the lens. In view of this, we provide a protective film inner wall gluing device. Utility Model Content

When one of the splints 401 moves, the linkage rack 4010 is meshed with the linkage gear 402. The linkage gear 402 and the linkage rack 4010 drive the splint 401 on the other side to move along the limiting slide 406 toward the side of the protective film. The positioning cylinder 403 is driven to make the splints 401 on both sides of the positioning frame 4 move inward or outward along the limiting slide 406 at the same time. After fixing the protective film with the splint 401, the lifting motor 301 on the top surface of the second connecting frame 3 is driven. By aligning the bottom surface of the lifting plate 305 with the outer wall of the top of the positioning frame 4 When the driving gear 302 is fixed and driven by the lifting motor 301, the lifting rack 306 on one side of the driving gear 302 is connected to the inner core of the driving gear 302, and the lifting rack 306 drives the lifting plate 305 and the clamping plate 401 to slide vertically upward along the lifting guide rail 303, and glues the inner wall of the protective film through the glue coating hose 205 at the bottom of one side of the first connecting frame 2, so that the device can effectively complete the glue coating operation on the inner wall of the protective film through the mutual cooperation between the clamping plate 401, the lifting rack 306 and the glue coating hose 205, so that the device can effectively avoid the quality problem of the protective film caused by uneven glue coating when in use, or cause the protective film to be displaced due to uneven glue coating when it is put into use, resulting in the protective film being unable to protect the lens.

[0026] By installing the device next to the intermittent conveyor belt, when the protective film is located directly below the glue coating tube 204, the positioning cylinder 403 is driven to make one of the splints 401 move horizontally toward the bottom of the glue coating tube 204. When one of the splints 401 moves, the linkage rack 4010 engages with the linkage gear 402. The linkage gear 402 and the linkage rack 4010 drive the splint 401 on the other side to move along the limiting slide 406 toward the side of the protective film. By driving the positioning cylinder 403, the splints 401 on both sides of the positioning frame 4 move inward or outward along the limiting slide 406 at the same time, so that the device can effectively clamp the protective film, which is convenient for the subsequent gluing of the inner wall of the protective film through the glue coating tube 204.

[0027] like Figure 1 and Figure 5 As shown, the lifting motor 301 passes through one side of the outer wall of the second connecting frame 3 and is fixedly connected to the driving gear 302, and the outer wall of the driving gear 302 is rotatably connected to the outer wall of the top of the second connecting frame 3, and the outer wall of the second connecting frame 3 away from the lifting motor 301 is fixedly connected to a group of lifting guide rails 303, and the lifting guide rails 303 are located on both sides of the outer wall of the second connecting frame 3, and the outer wall of the lifting guide rail 303 is connected to the slider 304 near the bottom end, and one side of the outer wall of the lifting guide rail 303 is slidably connected to the inner side of the slider 304, and the outer wall of the slider 304 is fixedly connected to the lifting plate 305 on the side away from the second connecting frame 3, and the bottom surface of the lifting plate 305 is fixedly connected to the outer wall of the top of the positioning frame 4, and the outer wall of the lifting plate 305 is fixedly connected to the lifting rack 306 on the side close to the second connecting frame 3, and the lifting rack 306 is located on the side of the driving gear 302, and the lifting rack 306 and the driving gear 302 are meshed with each other and rotatably connected.

[0028] After the protective film is fixed by the splint 401, the lifting motor 301 on the top surface of the second connecting frame 3 is driven. By fixing the bottom surface of the lifting plate 305 to the outer wall of the top of the positioning frame 4, when the driving gear 302 is driven by the lifting motor 301, the lifting rack 306 on one side of the driving gear 302 passes through the inner core of the driving gear 302, and the lifting rack 306 drives the lifting plate 305 and the splint 401 to slide vertically upward along the lifting guide rail 303, and applies glue to the inner wall of the protective film through the glue coating hose 205 at the bottom of one side of the first connecting frame 2, so that the device can effectively complete the glue coating operation on the inner wall of the protective film through the mutual cooperation between the splint 401, the lifting rack 306 and the glue coating hose 205, so that the device can effectively avoid the quality problem of the protective film caused by uneven glue coating when in use, or cause the protective film to be displaced due to uneven glue coating when it is put into use, resulting in the protective film being unable to protect the lens.

The linkage gear 402 and the linkage rack 4010 drive the splint 401 on the other side to move along the limiting slide 406 toward the side of the protective film. By driving the positioning cylinder 403, the splints 401 on both sides of the positioning frame 4 move inward or outward along the limiting slide 406 at the same time. After the protective film is fixed by the splint 401, the splint 401 is driven. The lifting motor 301 on the top surface of the second connecting frame 3 is driven, and the bottom surface of the lifting plate 305 is fixed to the outer wall of the top of the positioning frame 4. When the driving gear 302 is driven by the lifting motor 301, the lifting rack 306 on one side of the driving gear 302 is connected to the inner core of the driving gear 302, and the lifting rack 306 drives the lifting plate 305 and the clamping plate 401 to slide vertically upward along the lifting guide rail 303, and glues the inner wall of the protective film through the glue coating hose 205 at the bottom of one side of the first connecting frame 2, so that the device effectively completes the glue coating operation on the inner wall of the protective film through the mutual cooperation between the clamping plate 401, the lifting rack 306 and the glue coating hose 205.
