Description

Technical Field

[0002] Laser film generally adopts computer dot lithography technology, 3D true color holographic technology, multiple and dynamic imaging technology, etc. From the perspective of product composition, laser film products can be roughly divided into three types: OPP laser film, PET laser film and PVC laser film. Laser packaging is a sub-industry in the packaging industry and has achieved rapid development. Compared with other products in the packaging industry, laser packaging materials not only have novel and bright appearance effects, but also have high-tech anti-counterfeiting functions. They are known as the most cutting-edge technical products in the world's packaging and printing industry. The application fields of laser materials are already very wide, and they have been rapidly promoted in industries such as food, medicine, daily chemicals, tobacco and alcohol, clothing, gift packaging, and decorative materials.

[0003] During processing, the laser film generally presents a continuous belt structure, which is transmitted by multiple conveyor rollers and guide rollers. In this process, the overall tension of the laser film belt needs to be ensured. If the laser film belt is too loose, it may cause creases on the final laser film roller, so a tensioning structure is needed to tension the laser film belt. However, the current tensioning structure is relatively simple. When adjusting the tension, it is only done by adjusting the height of the support roller. There is no buffer structure. During the adjustment process, tension transition may occur, resulting in damage to the laser film belt.

[0004] Therefore, how to achieve a certain buffer structure when adjusting the tension of the laser film tape without causing damage to the laser film tape is a technical problem that needs to be solved urgently in the industry. Utility Model Content

[0020] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Reference Figure 1-3 , an embodiment of the utility model is proposed, an automatically adjustable tensioning structure for laser film processing, comprising a device table 1 and two adjustment mechanisms;

[0022] The two side surfaces of the device platform 1 are fixedly connected with connection seats 2, the tops of the two connection seats 2 are vertically fixedly connected with electric control telescopic rods 3, and the two adjustment mechanisms are respectively arranged at the tops of the two electric control telescopic rods 3;

[0023] The structures of the two adjustment mechanisms are the same, one of the adjustment mechanisms includes a connecting block 4 fixedly connected to the top of the electric-controlled telescopic rod 3, the top of the connecting block 4 is vertically fixedly connected to a column 5, the upper and lower parts of the outer surface of the column 5 are respectively vertically slidably connected to an upper sliding ring 8 and a lower sliding ring 7, the upper surface of the lower sliding ring 7 is vertically fixedly connected to a plurality of guide rods 9, the tops of the plurality of guide rods 9 all pass through the upper sliding ring 8 and extend upward, a spring 10 is fixedly connected between the upper sliding ring 8 and the lower sliding ring 7 and on the outer surfaces of the plurality of guide rods 9, the top of the column 5 is fixedly connected to a fixing block 6, one side surface of the fixing block 6 and one side surface of the connecting block 4 are respectively laterally fixedly connected to an upper fixing block 12 and a lower fixing block 11, a threaded rod 13 is vertically rotatably connected between the upper fixing block 12 and the lower fixing block 11, the outer surface of the threaded rod 13 is threaded with a threaded sleeve 14, and the threaded sleeve 14 is fixedly connected to the outer surface of the lower sliding ring 7.

[0024] When the device is in use, the adjustment mechanism is driven to move in the vertical direction by extending and shortening the electrically-controlled telescopic rod 3, thereby adjusting the tension of the laser film. At the same time, in the process of adjusting the tension, since multiple springs 10 are arranged between the upper sliding ring 8 and the lower sliding ring 7 of the device, the multiple springs 10 can play a buffering role, and the laser film will not be directly and rigidly tensioned, thereby avoiding damage to the laser film due to excessive tension, thereby improving the practicality of the device.

[0025] When the structure is in use, the tension of the spring 10 can be adjusted by adjusting the position of the lower sliding ring 7. During the adjustment, the threaded sleeve 14 can be driven to move in the height direction by rotating the threaded rod 13, thereby driving the height of the lower sliding ring 7 fixedly connected to the threaded sleeve 14. When the distance between the lower sliding ring 7 and the upper sliding ring 8 becomes smaller, the spring 10 between the two will be compressed, and the pressure applied to the upper sliding ring 8 will become larger, thereby reducing the buffering capacity of the device and ensuring the tensioning effect on the laser film. On the contrary, the buffering capacity of the device will be improved to prevent the laser film from being damaged.

[0026] Furthermore, the surfaces of the two upper slip rings 8 on the opposite sides are fixedly connected with device blocks 16 , the surfaces of the two device blocks 16 on the opposite sides are provided with sliding grooves 17 , and the insides of the two sliding grooves 17 are vertically slidably connected with sliding blocks 18 .

[0027] A support roller 20 is rotatably connected between the two sliding blocks 18 .

[0028] Pressure sensors 19 are provided at the bottom ends of the two slide grooves 17 .

[0029] The support roller 20 located between the two sliding blocks 18 is used to support the laser film belt. The pressure sensor 19 at the bottom of the slide slot 17 can monitor the pressure on the support roller 20 in real time and transmit data to the controller, which will adjust the tension of the device according to the data.

[0030] Furthermore, the central axes of the column 5, the upper sliding ring 8 and the lower sliding ring 7 are located in the same straight line.

[0031] The central axes of the column 5, the upper sliding ring 8 and the lower sliding ring 7 are located in the same straight line, which can ensure that these structures can operate smoothly.

[0032] Furthermore, a servo motor 15 is fixedly connected to the bottom end of the lower fixing block 11 , and an output shaft of the servo motor 15 rotatably passes through the lower fixing block 11 and is fixedly connected to the bottom end of the threaded rod 13 .

[0033] The output shaft of the servo motor 15 is connected to the threaded rod 13 , and can drive the threaded rod 13 to rotate so as to adjust the position of the lower sliding ring 7 .

[0034] When the device is in use, the adjustment mechanism is driven to move in the vertical direction by extending and shortening the electrically-controlled telescopic rod 3, thereby adjusting the tension of the laser film. At the same time, in the process of adjusting the tension, since multiple springs 10 are arranged between the upper sliding ring 8 and the lower sliding ring 7 of the device, the multiple springs 10 can play a buffering role, and the laser film will not be directly and rigidly tensioned, thereby avoiding damage to the laser film due to excessive tension, thereby improving the practicality of the device.

[0035] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
