Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot stamping film production technology, and in particular to a substrate positioning device for a hot stamping film production adhesive dot hot press laminating machine. Background Technology
[0002] The hot-press laminating machine for hot stamping film production is a core processing equipment in the hot stamping film production process. Its main function is to laminate hot stamping film (usually a thin film substrate containing a metal plating layer or pattern layer) with a base substrate (such as PET, PVC, paper, etc.) through the process of "adhesive dot coating - precise bonding - hot pressing and curing". Specifically, the equipment first coats the surface of the base substrate with hot melt adhesive dots according to a preset pattern or evenly distributed through the adhesive dot coating mechanism. Then, the hot stamping film and the coated base substrate are transported to the laminating station. A specific temperature (usually 60-120℃) and pressure (0.3-0.8MPa) are applied by the upper and lower hot press rollers, which make the hot melt adhesive dots melt and solidify quickly, tightly bonding the hot stamping film and the base substrate to form a composite substrate with hot stamping effect.
[0003] However, existing hot-press laminating machines for hot-stamping film production have the following drawbacks: during the substrate conveying process, if the substrate deviates, there is a lack of real-time detection and automatic adjustment mechanisms. The machine must be stopped and adjusted manually after the deviation is detected. This not only affects production efficiency, but also causes wrinkles in the substrate due to changes in conveying tension before and after the machine stops. In addition, the accuracy of manual adjustment is limited, which can easily lead to inaccurate alignment when the hot-stamping film and the substrate are laminated, reducing the product qualification rate.
[0004] Therefore, a substrate positioning device for a hot-press laminating machine for hot stamping film production is proposed to facilitate adaptive positioning and adjustment of the substrate, thereby improving the yield of the substrate. Utility Model Content
[0005] Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a substrate positioning device for a hot-press laminating machine for hot-stamping film production. This device solves the problem that existing hot-stamping film production machines lack real-time detection and automatic adjustment mechanisms when substrate misalignment occurs during transport. Manual intervention is required to detect the misalignment and stop the machine for adjustment, which not only affects production efficiency but also causes substrate wrinkling due to changes in transport tension before and after stopping. Furthermore, the limited precision of manual adjustment easily leads to inaccurate alignment between the hot-stamping film and the substrate during lamination, reducing product qualification rates.
[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0019] This application provides a substrate positioning device for a hot-press laminating machine for hot-stamping film production. This effectively solves the technical problem of existing hot-stamping film production machines where substrate misalignment during transport lacks real-time detection and automatic adjustment mechanisms. Manual intervention is required to detect the misalignment and stop the machine for adjustment, which not only affects production efficiency but also causes substrate wrinkling due to changes in transport tension before and after stopping. Furthermore, the limited precision of manual adjustment easily leads to inaccurate alignment between the hot-stamping film and the substrate, reducing product qualification rates. This device uses a positioning detector 31 to detect substrate misalignment in real time, and a controller 3 to receive signals and drive a motor 21 and a threaded rod 22 to move the first slider 41 and limiting components. This automatic adjustment structure achieves real-time adaptive adjustment after substrate misalignment, eliminating the need for manual intervention and effectively improving production efficiency while avoiding the inaccuracies and substrate wrinkling problems caused by manual adjustment.
[0020] Example
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application effectively solves the technical problem that existing hot stamping film production adhesive dot hot press laminating machines lack real-time detection and automatic adjustment mechanisms when substrate shifts during transport. Manual intervention is required to detect the shift and stop the machine for adjustment, which not only affects production efficiency but also causes substrate wrinkling due to changes in transport tension before and after stopping. Furthermore, the limited precision of manual adjustment easily leads to inaccurate alignment between the hot stamping film and the substrate, reducing product qualification rate. The overall concept is as follows: A substrate positioning device for a hot stamping film production adhesive dot hot press laminating machine includes an adhesive dot hot press laminating machine frame 1. The frame 1 is equipped with a positioning mechanism to facilitate substrate positioning. The positioning mechanism includes a top slide rail 2, a controller 3, a secondary guide rail 4, and a first limiting ring 5. The top slide rail 2 is fixedly installed at the upper end of the adhesive dot hot press laminating machine frame 1, the controller 3 is fixedly installed at the side end of the frame 1, and the secondary guide rail 4 is located at the lower end of the controller 3. The lower end of the first limiting ring 5 is provided with a second limiting ring 52. The glue dot hot press laminating frame 1 is provided with an active roller 11 and a driven roller 12. The driven roller 12 is located at the lower end of the active roller 11. The side end of the top slide rail 2 is fixedly installed with a motor 21. The output end of the motor 21 is fixedly installed with a threaded rod 22. The threaded rod 22 is rotatably installed through the inner side wall of the top slide rail 2. The side end of the glue dot hot press laminating frame 1 is fixedly installed with a positioning detector 31. The positioning detector 31 is installed at the discharge point of the driven roller 12. The positioning detector 31, the motor 21 and the controller 3 are all connected by a transmission line. When the substrate is adjusted and positioned, the substrate passes between the active roller 11 and the driven roller 12 and is conveyed to the subsequent process. The positioning detector 31 installed at the discharge point of the driven roller 12 detects the edge position of the substrate in real time. When the substrate is offset, the positioning detector 31 transmits the offset signal to the controller 3 at the side end of the glue dot hot press laminating frame 1 through the transmission line.
[0022] A first slider 41 is fixedly installed at the upper end of the secondary guide rail 4. The first slider 41 is slidably installed on the inner side wall of the top guide rail 2. A first threaded groove 42 is opened through the side end of the first slider 41. A threaded rod 22 is rotatably installed on the inner side wall of the first threaded groove 42. A double-ended screw 43 is rotatably installed through the side end of the secondary guide rail 4. Two first limiting rings 5 are slidably installed on the driving roller 11. Two second limiting rings 52 are slidably installed on the driven roller 12. A connecting rod 51 is fixedly installed between the two first limiting rings 5 and the two second limiting rings 52. After receiving the signal, the controller 3 sends a control command to the motor 21 at the side end of the top slide rail 2 via the transmission line. The motor 21 starts and drives the threaded rod 22 at its output end to rotate. Since the threaded rod 22 is installed on the inner wall of the first threaded groove 42 of the first slider 41 through the thread and the first slider 41 is fixedly connected to the auxiliary guide rail 4, the rotation of the threaded rod 22 will drive the first slider 41 to slide along the inner wall of the top slide rail 2, thereby driving the auxiliary guide rail 4 and the first limiting ring 5 and the second limiting ring 52 connected to it to move synchronously, pushing the substrate back to the preset conveying path.
[0023] Two first limiting rings 5 are each fixedly mounted with a second slider 53 at their upper ends. Both second sliders 53 are slidably mounted on the inner wall of the secondary guide rail 4. Each second slider 53 has a second threaded groove 54 extending through its side end. A double-ended screw 43 is threadedly mounted on the inner wall of the two second threaded grooves 54. When this device generates hot stamping film, pre-positioning adjustment can be made according to the width of the substrate to be processed. The operator manually rotates the double-ended screw 43 at the side end of the secondary guide rail 4. Because the double-ended screw 43 is threadedly mounted on the inner wall of the two second sliders 53... The inner wall of the double-threaded groove 54 is fixedly connected to the two first limiting rings 5 respectively. The first limiting rings 5 and the second limiting rings 52 are fixed together by the connecting rod 51. Therefore, when the double-headed screw 43 rotates, it will drive the two second sliding blocks 53 to slide synchronously in opposite directions along the inner wall of the auxiliary guide rail 4, thereby driving the two first limiting rings 5 to slide along the driving roller 11 and the two second limiting rings 52 to slide along the driven roller 12 until the two first limiting rings 5 and the two second limiting rings 52 are respectively attached to the two sides of the substrate, completing the pre-positioning that matches the width of the substrate.
[0024] To address the problems existing in the prior art, this utility model provides a substrate positioning device for a hot-press laminating machine for hot-stamping film production. This device uses a positioning detector 31 to detect substrate offset in real time, and a controller 3 to receive signals and drive a motor 21 and a threaded rod 22 to move the first slider 41 and the limiting component. This automatic adjustment structure achieves real-time adaptive adjustment after substrate offset, without the need for manual intervention, effectively improving production efficiency, and avoiding the problems of insufficient accuracy and substrate wrinkles caused by manual adjustment.
[0025] Working principle:
[0026] When this device generates hot stamping film, it first performs a pre-positioning adjustment based on the width of the substrate to be processed. The operator manually rotates the double-ended screw 43 at the side end of the auxiliary guide rail 4. Since the double-ended screw 43 is screwed and rotated on the inner wall of the second thread groove 54 of the two second sliders 53, and the two second sliders 53 are respectively fixedly connected to the two first limiting rings 5, and the first limiting rings 5 and the second limiting rings 52 are fixed together by a connecting rod 51, the rotation of the double-ended screw 43 will drive the two second sliders 53 to slide synchronously in opposite directions along the inner wall of the auxiliary guide rail 4, thereby driving the two first limiting rings 5 to slide along the driving roller 11 and the two second limiting rings 52 to slide along the driven roller 12, until the two first limiting rings 5 and the two second limiting rings 52 are respectively attached to the two side edges of the substrate, completing the pre-positioning adapted to the width of the substrate. When the adjustment is completed and the substrate is transported and positioned, the substrate is moved from the driving roller 11 and the driven roller 12. The substrate passes between the driven rollers 12 and is conveyed to the subsequent process. The positioning detector 31 installed at the discharge point of the driven rollers 12 detects the edge position of the substrate in real time. When the substrate is offset, the positioning detector 31 transmits the offset signal to the controller 3 at the side end of the glue dot hot press composite frame 1 through the transmission line. After receiving the signal, the controller 3 sends a control command to the motor 21 at the side end of the top slide rail 2 through the transmission line. The motor 21 starts and drives the threaded rod 22 at its output end to rotate. Since the threaded rod 22 is installed on the inner wall of the first threaded groove 42 of the first slider 41 through the thread and the first slider 41 is fixedly connected to the secondary guide rail 4, the rotation of the threaded rod 22 will drive the first slider 41 to slide along the inner wall of the top slide rail 2, thereby driving the secondary guide rail 4 and the first limiting ring 5 and the second limiting ring 52 connected to it to move synchronously, pushing the substrate back to the preset conveying path, and realizing the adaptive adjustment after the substrate is offset. Existing hot stamping film production adhesive dot hot press laminating machines lack real-time detection and automatic adjustment mechanisms when substrate shifts during transport. Manual intervention is required to detect the shift and stop the machine for adjustment, which not only affects production efficiency but also causes substrate wrinkling due to changes in transport tension before and after stopping. Furthermore, manual adjustment has limited precision, easily leading to misalignment between the hot stamping film and the substrate during lamination, reducing product yield. This device utilizes a positioning detector 31 to detect substrate shift in real time, and a controller 3 to receive signals and drive the motor 21 and threaded rod 22 to move the first slider 41 and limiting components. This automatic adjustment structure enables real-time adaptive adjustment after substrate shift, eliminating the need for manual intervention and effectively improving production efficiency while avoiding the inaccuracies and substrate wrinkling problems caused by manual adjustment.
[0027] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
