DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] Example
[0027] See also Figure 1-Figure 4, a decorative film printing device and a printing method thereof shown in the figure include a frame 1, two telescopic rods 2 are arranged inside the frame 1, each telescopic rod 2 is fixedly connected to a bracket 3, each bracket 3 is rotatably connected to a roller shaft 4, each bracket 3 is tightly pressed with a linkage rod 5, a spring 6 is arranged in the middle of the linkage rod 5, a support frame 7 is arranged inside the linkage rod 5, an auxiliary roller shaft 8 is arranged inside the support frame 7, a fixed rod 9 is arranged on one side of the auxiliary roller shaft 8, sliding blocks 10 are fixedly connected at both ends of the fixed rod 9, each sliding block 10 is slidably connected to a pressure rod 11, the sliding block 10 is slidably connected to a fixed plate 13, each sliding block 10 is gear-engaged with a gear mechanism 14, the other end of the support frame 7 is tightly pressed with a base 15, the base 15 is provided with a drag chain motor 16, a support platform 17 is arranged below the base 15, the base 15 is slidably connected to a digital printing body 18, one end of the digital printing body 18 is fixedly connected to one end of the drag chain motor 16, a drying mechanism 19 is arranged on one side of the support platform 17, and an ink barrel 20 is arranged below the support platform 17.
[0028] Furthermore, the two ends of the pressure rod 11 are tightly pressed against one end of the spring 2 12, the spring 2 12 is arranged inside the sliding block 10, and the other end of the spring 2 12 is tightly pressed against the inner wall of the sliding block 10. By tightly pressing one end of the spring 2 with the two ends of the pressure rod, the spring 2 is cleverly embedded in the internal space of the sliding block, ensuring that the spring 2 can function stably when under pressure, and its performance will not be affected by position offset or external force interference. Furthermore, the other end of the spring 2 is also tightly pressed against the inner wall of the sliding block, forming a stable and elastic connection structure. During the printing process, even when facing decorative films of different materials, thicknesses or tensions, the stable connection between the pressure rod, the spring and the sliding block can ensure the smooth progress of the printing operation, avoiding the occurrence of printing due to the unevenness of the decorative film, thereby ensuring the best printing effect.
[0029] Furthermore, the gear mechanism 14 includes a gear 1401, and a positioning pin 1402 is provided inside the gear 1401. The positioning pin 1402 is plugged into one end of a spring disk 1403, and the other end of the spring disk 1403 is plugged into a linkage shaft 1404. The linkage shaft 1404 is fixedly connected to the inner wall of the support frame 7, and the linkage shaft 1404 is rotatably connected to the gear 1401. The gear mechanism is mainly composed of gears, and a positioning pin is cleverly provided inside the gear. The positioning pin is plugged into one end of the spring disk, and the other end of the spring disk is connected to the linkage shaft. The linkage shaft is fixedly connected to the inner wall of the support frame, so that the gear can store a certain amount of force during the rotation process, so that its sliding block can automatically restore its initial position, thereby reducing the energy consumption of the equipment.
[0030] Furthermore, the gear 1401 is meshedly connected to the sliding block 10. The bottom surface of the sliding block 10 is provided with gear teeth. The meshing connection is achieved through the gear and the sliding block. The gear teeth and the gear teeth specially provided on the bottom surface of the sliding block mesh with each other, forming a stable and precise connection. It ensures that when the gear rotates, it can accurately transmit power to the sliding block, driving it to move precisely along a preset trajectory, realizing precise power transmission, and avoiding the appearance of printing due to the unevenness of the decorative film, thereby ensuring the accuracy and consistency of the printing operation.
[0031] Furthermore, a sliding rod 1001 is provided inside the sliding block 10, and the sliding rod 1001 is slidably connected to the pressure rod 11. The sliding rod is provided inside the sliding block, and a sliding connection is achieved between the sliding rod and the pressure rod, allowing the pressure rod to move smoothly and accurately inside the sliding block through the sliding rod when subjected to external force, thereby ensuring that during the printing process, no matter what shape, size or material of the decorative film is, the sliding rod can ensure that the pressure rod can be quickly and accurately adjusted to meet different printing requirements, thereby ensuring the accuracy and consistency of the printing operation.
[0032] Furthermore, a limiting groove is provided on the fixed plate 13, and the limiting groove is slidably connected to the sliding block 10. A plurality of limiting grooves are provided on the fixed plate. The limiting grooves are not provided randomly, but are designed according to the shape and size of the sliding block to ensure that the sliding block can slide freely and stably therein. The sliding block, as the core moving component in the printing operation, achieves a precise sliding connection on the fixed plate through the close fit between its outer contour and the limiting groove, effectively preventing the sliding block from shifting or shaking during movement, ensuring the precise positioning of the sliding block in the printing operation, thereby improving the accuracy and consistency of printing.
[0033] In this solution, the workflow is: place the decorative film on the support table 17 and ensure that it is flat and wrinkle-free.
[0034] The height of the telescopic rod 2 is adjusted to keep the roller 4 at an appropriate distance from the surface of the decorative film.
[0035] The drag chain motor 16 is started, and the printing pattern information is loaded into the control system through the digital printing body 18 .
[0036] The drag chain motor 16 drives the digital printing body 18 to slide on the support platform 17, and at the same time, the digital printing body 18 performs inkjet printing on the decorative film according to a preset pattern.
[0037] During the printing process, the roller 4 and the auxiliary roller 8 work together to ensure that the decorative film moves forward smoothly and avoids wrinkles and deviations.
[0038] The sliding block 10 slides in the limiting groove of the fixed plate 13, and the gear mechanism 14 meshes with the gear teeth on the bottom surface of the sliding block 10 through the gear 1401, driving the sliding block 10 and the pressure rod 11 connected thereto to move up and down accurately to control the printing pressure.
[0039] The spring 6 and the spring 2 12 play a buffering and stabilizing role in the printing process to ensure the uniformity of the printing quality.
[0040] After printing is completed, the decorative film enters the drying mechanism 19 for drying to fix the printed pattern and improve the quality of the finished product.
[0041] The dried decorative film is taken out from the end of the device, completing the entire printing process.
[0042] Turn off the drag chain motor 16 and other related equipment, and carry out necessary cleaning and maintenance work.
