Description

Technical Field

[0001] This invention relates to the field of photo lamination technology, specifically to an automatic photo lamination device. Background Technology

[0002] Photo printing lamination is used to enhance the durability and aesthetics of photo prints. It is mainly applied to the processing of photo prints such as posters and display boards. By laminating the photo prints, dust and minor scratches from the external environment can be effectively resisted, thereby extending the lifespan of the photo prints. At the same time, different visual effects such as highlights and matte finishes can be given to the image according to requirements.

[0003] The automatic lamination of photographic images involves fixing the film roll wound with film through a film unwinding mechanism, and using a drive component to rotate the film roll to unwind the film. The photographic image is then smoothly transported by a conveyor mechanism and initially aligned and bonded with the unwound film. The bonded composite structure enters the pressing component, where pressure is applied by a heating roller and a pressure roller to complete the lamination process.

[0004] Currently, the photo printing laminating equipment uses a bolt-fixed film-laying mechanism, where bolts lock the fixing flanges at both ends of the film roller to the device bracket. However, when the film roll is used up and needs to be replaced with a new roll or a film fabric with a different visual effect, the operator must first use tools to remove the fixing bolts on both sides of the film roller, remove the old film roller, install the new film roll, realign the bolt holes, and tighten the bolts one by one. This process of removing and installing bolts consumes a lot of time, thus significantly reducing overall production efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic laminating device for photographic images. It solves the problem that when a film roll is used up and needs to be replaced with a new one or a film cloth with different visual effects, the operator must first use tools to remove the fixing bolts on both sides of the film roller, remove the old film roller, install the new film roll, realign the bolt holes, and tighten the bolts one by one. This process consumes a lot of time and reduces production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic laminating device for photographic images, comprising a first fixing frame, a quick-release assembly, a connecting assembly, a laminating roller, a guiding assembly, and a conveying assembly. The quick-release assembly includes a fixing rod, a slider, a bidirectional lead screw, a forward and reverse motor, a connecting block, and a limiting block. The fixing rod has a first groove inside. The connecting assembly includes a lower film roller mounting seat, an upper film roller mounting seat, and an insertion block. The insertion block has a first limiting hole inside. The lower film roller mounting seat has an insertion hole inside. The lower film roller mounting seat has a second limiting hole inside. The lower film roller mounting seat has a first film roller positioning groove inside. The upper film roller mounting seat has a second film roller positioning groove inside. A first positioning block is fixedly connected to the inner surface of the first film roller positioning groove, and a second positioning block is fixedly connected to the inner surface of the second film roller positioning groove. The laminating roller has a fixing groove inside.

[0007] Preferably, the inner surface of the first groove is slidably connected to the slider, the inner surface of the slider is threadedly connected to the bidirectional lead screw, and the left surface of the fixing rod is fixedly connected to the forward and reverse motor.

[0008] Preferably, the output end of the forward and reverse motor is fixedly connected to the bidirectional lead screw, the side surface of the connecting block is fixedly connected to the slider, the side surface of the connecting block is fixedly connected to the first limiting block, the upper surface of the insertion block is fixedly connected to the upper film roller mounting seat, and the upper surface of the first fixing frame is fixedly connected to the lower film roller mounting seat.

[0009] Preferably, the inner surface of the insertion hole is slidably connected to the insertion block, the inner surface of the first limiting hole is slidably connected to the limiting block, and the inner surface of the second limiting hole is slidably connected to the limiting block.

[0010] Preferably, a second fixed frame is fixedly connected to the upper surface of the first fixed frame. The guide assembly includes an electric telescopic rod, a first fixed block, a telescopic rod, a spring, a second fixed block, a rotating shaft, and a guide roller. The top inner wall of the second fixed frame is fixedly connected to the electric telescopic rod. The lower surface of the electric telescopic rod is fixedly connected to the first fixed block. The lower surface of the first fixed block is fixedly connected to the telescopic rod. The lower surface of the first fixed block is fixedly connected to the spring.

[0011] Preferably, the lower surface of the telescopic rod is fixedly connected to the second fixed block, the lower end of the spring is fixedly connected to the second fixed block, the telescopic rod passes through the inside of the spring, a rotating shaft is rotatably connected to the inner surface of the second fixed block, and a guide roller is fixedly connected to the side surface of the rotating shaft.

[0012] Preferably, the side surface of the laminating roller is provided with a heat-mounting film roll, the side surface of the laminating roller is fixedly connected with an anti-slip ring, the upper surface of the first fixing frame is fixedly connected with a third fixing frame, the top inner wall of the third fixing frame is fixedly connected with a hot air box, and the front surface of the third fixing frame is fixedly connected with a controller.

[0013] Working principle: When a new laminating roll or a roll with a different visual effect needs to be replaced, the forward and reverse motors are started to drive the bidirectional lead screw to rotate. The two connecting blocks on the bidirectional lead screw move in opposite directions to both ends, causing the limiting block to leave the first limiting hole and the second limiting hole to no longer limit the insertion block. This allows the insertion block under the upper film roller mounting seat to be easily removed from the insertion hole. The operator can remove the laminating roll and the heat-laminating film roll from the first film roller positioning groove by holding both ends of the laminating roll. The two ends of the new laminating roll are placed in the first film roller positioning groove, so that the fixing groove on the laminating roll is in contact with the first positioning block, limiting the laminating roll. The insertion block is placed in the insertion hole, and the forward and reverse motors are started to drive the two connecting blocks to move in opposite directions towards the center. The limiting block limits the insertion block and the upper film roller mounting seat. The first film roller positioning groove, the second film roller positioning groove, the first positioning block, and the second positioning block are set to keep the laminating roll in a stable position during use.

[0014] This invention provides an automatic laminating device for photographic images. It has the following beneficial effects: 1. By setting up quick-disassembly components and connecting components, this invention can quickly replace the film roll when it is necessary to replace it with a new film roll or a film roll with a different visual effect. During the process, operators do not need to find tools or use tools to disassemble multiple sets of bolt structures, eliminating the tool positioning, multiple thread loosening and tightening processes required for traditional bolt connections. This process reduces non-value-adding time in the production process, thereby improving the efficiency of film coating.

[0015] 2. By setting a first film roller positioning groove, a first positioning block and a second positioning block, the present invention can ensure the coaxiality and stability of the film coating roller installation, avoid film surface deviation, uneven pressing force and abnormal film surface stretching caused by poor coaxiality, ensure accurate image coverage, improve the stability of equipment use and ensure film coating quality.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] Please see the appendix Figure 1 - Appendix Figure 5This invention provides an automatic laminating device for photographic images, including a first fixing frame 1, a quick-release assembly 2, a connecting assembly 3, a laminating roller 8, a guiding assembly 13, and a conveying assembly 16. The conveying assembly 16 employs conventional technology in the field, its core function being to drive a motor to output power, causing the conveying roller and transmission belt to rotate in tandem, thereby achieving stable conveying of the photographic images. The specific structure and working principle of this assembly are existing mature technologies and will not be described in detail here. The quick-release assembly 2 includes a fixing rod 201, a slider 203, a bidirectional lead screw 204, a forward and reverse motor 205, a connecting block 206, and a limiting block 207. The fixing rod 201 has a first groove 202 inside. The inner surface of 202 is slidably connected to the slider 203, the inner surface of the slider 203 is threadedly connected to the bidirectional lead screw 204, the left surface of the fixed rod 201 is fixedly connected to the forward and reverse motor 205, the output end of the forward and reverse motor 205 is fixedly connected to the bidirectional lead screw 204, the side surface of the connecting block 206 is fixedly connected to the slider 203, and the side surface of the connecting block 206 is fixedly connected to the first limiting block 207. The slider 203, the connecting block 206 and the first limiting block 207 are symmetrically arranged on the bidirectional lead screw 204, and the fixed rod 201 is symmetrically arranged front and back. When the forward and reverse motor 205 is started, it drives the bidirectional lead screw 204 to rotate, and the two connecting blocks 206 on the bidirectional lead screw 204 move in opposite directions to both ends or in opposite directions to the center.

[0020] The connecting component 3 includes a lower film roller mounting base 301, an upper film roller mounting base 302, and an insertion block 303. The upper surface of the insertion block 303 is fixedly connected to the upper film roller mounting base 302, and the upper surface of the first fixing bracket 1 is fixedly connected to the lower film roller mounting base 301, increasing the stability of the structural connection. The insertion block 303 has a first limiting hole 304 inside, and the lower film roller mounting base 301 has an insertion hole 305 inside. The insertion block 303 is fixed to the upper film roller mounting base 302 and slides with the insertion hole 305 to form a preliminary positioning structure. In use, the insertion block 303 slides along the inner wall of the insertion hole 305, which can quickly guide the upper film roller mounting base 302 and the lower film roller mounting base 301 to align, avoiding deviations caused by manual alignment. At the same time, it bears part of the vertical load and prevents the upper film roller mounting base 302 from shaking. The lower film roller mounting base 301 has a first limiting hole 304 inside. The device has a second limiting hole 306, and the inner surface of the insertion hole 305 is slidably connected to the insertion block 303. The inner surface of the first limiting hole 304 is slidably connected to the limiting block 207. The inner surface of the second limiting hole 306 is slidably connected to the limiting block 207. After the insertion block 303 slides into the insertion hole 305, the limiting block 207 enters the second limiting hole 306 and the first limiting hole 304 under the action of the quick disassembly component 2, thus limiting the insertion block 303. This structure allows for quick replacement of the film roll when a new film roll or a film roll with different visual effects is needed. During the process, operators do not need to find tools or use tools to disassemble multiple sets of bolt structures, eliminating the tool positioning, multiple thread loosening and tightening processes required for traditional bolt connections. This process reduces non-value-added time in the production process, thereby improving the efficiency of film coating.

[0021] The lower film roller mounting base 301 is provided with a first film roller positioning groove 4 inside, and the upper film roller mounting base 302 is provided with a second film roller positioning groove 5 inside. The first film roller positioning groove 4 and the second film roller positioning groove 5 form an upper and lower matching installation space. After the two ends of the film coating roller 8 are embedded in the groove, its radial position is strictly limited to avoid the roller body from shaking and shifting when rotating, thus providing a basic installation reference for the film coating roller 8. A first positioning block 6 is fixedly connected to the inner surface of the first film roller positioning groove 4, and a second positioning block 7 is fixedly connected to the inner surface of the second film roller positioning groove 5. A fixing groove 10 is provided inside the film coating roller 8. The first positioning block 6, the second positioning block 7 and the fixing groove 10 of the film coating roller 8 form a concave-convex interlocking structure. The first positioning block 6 and the second positioning block 7 are embedded in the fixing groove 10, further constraining the film coating roller 8 and preventing relative slippage between the roller body and the mounting base. This structure can ensure the coaxiality and stability of the film coating roller 8 installation, avoid film surface deviation, uneven pressing force, abnormal film surface stretching and other film coating defects caused by poor coaxiality, ensure accurate image coverage, improve the stability of equipment use and ensure film coating quality.

[0022] A second fixed frame 12 is fixedly connected to the upper surface of the first fixed frame 1. The second fixed frame 12 serves as the mounting carrier for the guide assembly 13. Through its fixed connection with the first fixed frame 1, it provides stable support for the entire guide structure, ensuring that the guide roller 1307 will not fail due to force deviation when applying force to the photo printing image. This is the basic structural guarantee for the guide assembly 13. The guide assembly 13 includes an electric telescopic rod 1301, a first fixed block 1302, a telescopic rod 1303, a spring 1304, a second fixed block 1305, a rotating shaft 1306, and a guide roller 1307. The top inner wall of the second fixed frame 12 is fixedly connected to the electric telescopic rod 1301, and the lower surface of the electric telescopic rod 1301 is fixedly connected to the first fixed block 1302. The electric telescopic rod 1301 is designed to facilitate adjustment of the distance between the guide roller 1307 and the conveying assembly 16, adapting to photo printing images of different thicknesses. The device is highly flexible and applicable. The lower surface of the first fixing block 1302 is fixedly connected to the telescopic rod 1303, and the lower surface of the first fixing block 1302 is fixedly connected to the spring 1304. The lower surface of the telescopic rod 1303 is fixedly connected to the second fixing block 1305, and the lower end of the spring 1304 is fixedly connected to the second fixing block 1305. The telescopic rod 1303 passes through the interior of the spring 1304. The spring 1304 and the telescopic rod 1303 are configured as a guide roller 1307 to provide adaptive pressure. When there are local thickness fluctuations in the printed image, such as when there are bulges of adhesive layer at the edge of the image, the spring... 1304 adjusts the pressure of guide roller 1307 through compression and rebound to prevent the image from being damaged by rigid squeezing. The inner surface of the second fixing block 1305 is rotatably connected to the rotating shaft 1306, and the side surface of the rotating shaft 1306 is fixedly connected to the guide roller 1307. The guide roller 1307 directly contacts the photo image and guides the image to be transported along the preset path by its own rotation. At the same time, with the elastic pressure of the spring 1304, the image is flatly pressed onto the conveying component 16 to prevent wrinkles from appearing on the image before lamination, laying the foundation for accurate alignment of subsequent lamination.

[0023] A heat-laminating film roll 9 is provided on the side surface of the laminating roller 8. The heat-laminating film roll 9, as the core consumable carrier of the heat-laminating process, is directly fitted onto the side surface of the laminating roller 8. The film is released at a uniform speed through the rotation of the laminating roller 8, providing a heat-laminating protective layer for the photographic image. It is a basic material component for realizing the heat-laminating function. Anti-slip rings 11 are fixedly connected to the side surface of the laminating roller 8, closely adhering to both ends of the heat-laminating film roll 9, facilitating the operator's movement of the laminating roller 8. A third fixing bracket is fixedly connected to the upper surface of the first fixing bracket 1. The third fixed frame 14 provides stable support for the hot air box 15 and the controller 17 through a fixed connection with the first fixed frame 1, ensuring that the hot air box 15 can be accurately aligned with the film-coating area. The hot air box 15 is fixedly connected to the top inner wall of the third fixed frame 14 (prior art, publication number: CN114212302A), and the controller 17 is fixedly connected to the front surface of the third fixed frame 14. The forward and reverse motor 205, the heating element in the hot air box 15, and the electric telescopic rod 1301 in this application are all electrically connected to the controller 17.

[0024] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
