Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a laminating machine which is easy to change rolls. Background Art

[0002] Laminating machine is a device used to cover the surface of printed matter with plastic film. It is mainly used to protect paper, increase the protection of color printed images, and improve the gloss and appearance of the cover or printed matter. Laminating machine can be divided into two categories: instant laminating machine and pre-coating laminating machine. The coating laminating machine includes three parts: gluing, drying, and hot pressing.

[0003] In order to cover the plastic film on the surface of the printed matter, when the laminating machine is needed for assistance, the driving motor on the fixed plate is started in advance to rotate the unwinding roller, so that the film on the unwinding roller is unwound, and then the printed matter is sent into the machine through the guide roller. After that, the film and the printed matter pass between the heating roller and the pressure roller. At this time, the adhesive is activated, the film is compacted and adhered to the printed matter, and then the cooling roller on the base solidifies the adhesive and ensures the adhesion of the film, and then the plastic film is covered on the surface of the printed matter;

[0004] However, as the film on the unwinding roller is continuously unloaded, the staff often needs to replace the unwinding roller to ensure the normal operation of the laminating machine. However, the way the staff replaces the unwinding roller usually requires first canceling the limit on the unwinding roller, then laboriously removing the unwinding roller without the film from the laminating machine, and then moving the unwinding roller with the film to the position of the rotating roller to complete the replacement of the unwinding roller. This method of replacing the unwinding roller is relatively cumbersome and inconvenient, which leads to a long downtime of the laminating machine, thus affecting the use of the laminating machine.

Detailed implementation manners

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 6, the present utility model provides a technical solution: a film laminating machine that is easy to change rolls, including a base 1 and guide rollers 2. Both sides inside the base 1 are connected with guide rollers 2, and one side of the top of the base 1 is welded with a fixed plate 3. The fixed plate 3 is connected with a first unwind roller 4 through a driving motor. The middle part of the base 1 is sequentially connected with a pressure roller 5 and a heating roller 6 from top to bottom. And one side inside the base 1 near the pressure roller 5 is connected with a cooling roller 7. An auxiliary mechanism 8 is arranged on the outer wall of the first unwind roller 4. The auxiliary mechanism 8 includes a servo motor 801 connected to the base 1. And the output end of the servo motor 801 is butted with a first gear 802. A second gear 803 is meshed with the outer wall of the first gear 802. And a threaded column 804 is welded inside the second gear 803. And a fixing frame 805 is threadedly connected to the outer wall of the threaded column 804. The middle part of the outer wall of the fixing frame 805 is butted with a first limiting roller 806; A fixing seat 807 is welded on one side of the outer wall of the fixing frame 805 away from the first limiting roller 806. And a limiting plate 808 is welded inside the fixing seat 807; A guide frame 809 is slidably connected to the outer wall of the limiting plate 808. And a threaded rod 810 is threadedly connected to the bottom end inside the guide frame 809; The top end of the outer wall of the guide frame 809 is connected with a second limiting roller 811. And a second unwind roller 812 is connected to the outer wall of the second limiting roller 811; The second unwind roller 812 and the first unwind roller 4 are parallel to each other. One side of the outer wall of the threaded rod 810 is connected to the fixing frame 805 through a bearing seat; A guide post is slidably connected inside one side of the fixing frame 805 close to the threaded column 804. One side of the outer wall of the threaded column 804 is connected to the base 1 through a bearing seat; One side of the outer wall of the servo motor 801 is fixed to the base 1 through a mounting seat. The guide frame 809 and the fixing frame 805 are slidably connected. The fixing frame 805 and the base 1 are slidably connected. One side of the second unwind roller 812 away from the second limiting roller 811 is connected to the fixing plate 3 through a support seat.

[0022] During specific implementation, when the film on the first unwind roller 4 needs to be replaced during the process of covering the plastic film on the surface of the printed matter by the film laminating machine, first start the servo motor 801. Since the output end of the servo motor 801 is connected to the first gear 802, starting the servo motor 801 drives the first gear 802 to rotate. And because the first gear 802 and the second gear 803 are meshed, the rotation of the first gear 802 drives the second gear 803 to rotate. Then the rotation of the second gear 803 drives the threaded column 804 to rotate. And because the threaded column 804 and the fixing frame 805 are threadedly connected, the rotation of the threaded column 804 causes the fixing frame 805 to move away from the fixing plate 3. After that, the movement of the fixing frame 805 drives the guide frame 809 and the first limiting roller 806 to move together;

[0023] Until the first limiting roller 806 is disconnected from the first unwinding roller 4, immediately remove the first unwinding roller 4 from the first limiting roller 806. At this time, the second limiting roller 811 and the second unwinding roller 812 are still connected, so the second unwinding roller 812 will not fall. After that, as the fixing frame 805 continues to move, when the second limiting roller 811 is disconnected from the second unwinding roller 812, immediately remove the second unwinding roller 812 and dock it with the first limiting roller 806, and then start the reverse rotation of the servo motor 801 to make the fixing frame 805 move in the direction close to the fixing plate 3;

[0024] Until one side of the second unwinding roller 812 is connected to the fixing plate 3, thus completing the replacement of the roller. Then, there is no need to first laboriously cancel the limitation of the first unwinding roller 4 and then laboriously carry the second unwinding roller 812 from the position of the base 1 to the position of the first limiting roller 806. The replacement of the roller can be quickly completed, thereby reducing the downtime and improving the work efficiency. Therefore, when the laminating machine is in use, it plays a role in facilitating the quick replacement of the roller and improving the work efficiency;

[0025] After the replacement of the first unwinding roller 4 is completed, manually rotate the threaded rod 810 on the fixing seat 807 to make the guide frame 809 move away from the fixing plate 3. Since the guide frame 809 is connected to the second limiting roller 811, the movement of the guide frame 809 will drive the second limiting roller 811 to move together. And because the guide frame 809 is slidably connected with the limiting plate 808, at this time, the movement of the guide frame 809 is guided by the limiting plate 808 until the distance between the second limiting roller 811 and the fixing plate 3 is greater than the length of the second unwinding roller 812. Then connect the spare second unwinding roller 812 to the second limiting roller 811, and then rotate the threaded rod 810 to make the guide frame 809 move in the direction close to the fixing plate 3 until one side of the outer wall of the spare second unwinding roller 812 is connected to the fixing plate 3, thus placing the spare second unwinding roller 812 above the first limiting roller 806, which is convenient for the subsequent replacement of the roller. And the above operations can be carried out during the operation of the laminating machine, so there is no need to stop the laminating machine for operation.

[0026] In summary, when the film laminating machine that is easy to change the roll is in use, first start the drive motor on the fixing plate 3 to rotate the first unwind roller 4, so that the film on the first unwind roller 4 is exported. Then, the printed matter is sent into the machine through the guide roller 2. After that, the film and the printed matter pass between the pressure roller 5 and the heating roller 6. At this time, the adhesive is activated, the film is compacted and adhered to the printed matter. Then, the cooling roller 7 on the base 1 is used to cure the adhesive and ensure the adhesion of the film. Subsequently, the plastic film is covered on the surface of the printed matter. This is the prior art and will not be elaborated here. Through the auxiliary mechanism 8, the first limiting roller 806 is disconnected from the first unwind roller 4. At this time, the first unwind roller 4 is immediately removed, and then the second unwind roller 812 is removed and docked with the first limiting roller 806. Thus, there is no need to laboriously cancel the limitation on the first unwind roller 4, and then the second unwind roller 812 is laboriously carried from below to the position of the first limiting roller 806, and the roll can be replaced. Subsequently, the downtime is reduced and the work efficiency is improved. The content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
