Description

Technical Field

[0001] The utility model belongs to the technical field of ink smearing, and in particular relates to an ink smearing device. Background Art

[0002] PVC decorative film is made by applying colored ink on the PVC film to form patterns of different colors and different textures on the surface of the PVC film to improve the beauty of the PVC decorative film. The ink is mixed with different types of ingredients. Usually, a textured roller is used to dip the ink in the box and apply it on the PVC film. The prepared ink is placed in the box. The roller does not stir the ink during the process of dipping the ink. After a long period of sedimentation, the ink is prone to uneven ingredients and color differences.

[0003] The patent with application number 202021065635.7 discloses an ink smearing device for PVC decorative film, including a box with an opening upward, and also including an ink smearing mechanism, an ink scraping mechanism and a stirring mechanism for stirring the ink in the box, the ink smearing mechanism including a printing roller, the printing roller is located in the box and is rotatably connected to it, and one end of the printing roller is connected to a motor; the ink scraping mechanism is hinged on the inner wall of the box; the stirring mechanism includes a plurality of parallel stirring rods, the left and right ends of the stirring rods are respectively fixed on the inner wall of the box by bearings, and one end of the stirring rods passes through the inner wall of the box, and a driven gear is provided, and the driven gears are meshed and transmitted. A driving motor is provided outside the box, and a driving gear is provided on the output shaft of the driving motor. The driving gear is meshed and transmitted with any one of the driven gears, and a brush is provided outside the stirring rod.

[0004] The above technical solution uses an open box to store ink. As the water in the ink evaporates, its viscosity and color will deviate. At the same time, the above technical solution only controls the amount of ink dipped by a scraper. Since the printing roller is affected by different rotation speeds and centrifugal forces during rotation, the ink will be thrown out, and the position of the scraper cannot be kept constant due to the influence of the electric push rod. The scraper will also deviate after wear, resulting in the inability to accurately control the amount of ink on the printing roller. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] This specific embodiment is an ink coating device, and its structural schematic diagram is as follows Figure 1 , Figure 2 and Figure 3 As shown, the ink smearing device includes a mounting frame 1 and a storage box 5 arranged on the top of the mounting frame 1, a conveyor belt 2 is installed on the mounting frame 1, and conveyor rollers 10 for driving the conveyor belt 2 to rotate are rotatably arranged at both ends of the mounting frame 1, wherein support plates 4 for supporting the storage box 5 are fixed on both sides of the top surface of the mounting frame 1, a gearbox 6 is fixed on the top of the storage box 5, and an extrusion plate 18 is embedded in the storage box 5, an adjusting rod 17 threadedly inserted in the extrusion plate 18 is rotatably installed in the gearbox 6, a driving rod 15 is rotatably installed on the side wall of the support plate 4, the driving rod 15 drives the adjusting rod 17 to rotate through a gear mechanism, and a meshing mechanism is installed between the driving rod 15 and the conveyor roller 10.

[0028] A motor 3 is fixed to the side wall of the mounting frame 1, and the shaft of the motor 3 is fixedly connected to the conveying roller 10. The meshing mechanism includes a power gear 8 fixedly sleeved on the conveying roller 10 and the driving rod 15, and a toothed belt 9 is meshed between the two power gears 8. A transmission rod 7 is rotatably installed on the side wall of the gearbox 6. The gear structure includes a bevel gear 16 fixedly sleeved on the transmission rod 7 and the adjusting rod 17 and meshing with each other. A smearing roller 19 is rotatably installed in the opening at the bottom end of the storage box 5. In the process of the motor 3 driving the conveyor belt 2 to convey the product, the conveying roller 10 drives the driving shaft and the transmission rod 7 to rotate synchronously through the power gear 8 and the toothed belt 9. During the rotation, the adjusting rod 17 is driven to rotate through the two bevel gears 16. The adjusting rod 17 drives the extrusion plate 18 to move downward to extrude the ink, so that the ink is transported downward and smeared along with the conveying speed of the product.

[0029] like Figure 4As shown, a rotating tube 11 is rotatably sleeved between the transmission rod 7 and the driving rod 15, and a groove 14 penetrating the transmission rod 7 and the driving rod 15 is provided at the center position of the outer wall of the rotating tube 11, and an axial positioning block 13 is fitted and inserted in the groove 14. A bolt 12 threadedly inserted in the axial positioning block 13 is installed on the outer wall of the rotating tube 11. When ink is applied, the axial positioning block 13 is inserted into the groove 14 between the transmission rod 7 and the driving rod 15, and the bolt 12 is threadedly inserted in the axial positioning block 13 to keep the transmission rod 7 and the driving rod 15 fixed.

[0031] Working principle: The use of a closed storage box 5 reduces the evaporation of ink. When the motor 3 drives the conveyor belt 2 to convey the product, the conveying roller 10 rotates the drive shaft and the transmission rod 7 synchronously through the power gear 8 and the toothed belt 9. During the rotation, the two bevel gears 16 drive the adjusting rod 17 to rotate. The adjusting rod 17 drives the extrusion plate 18 to move downward to squeeze the ink, so that the ink is transported downward and applied along with the conveying speed of the product. When applying the ink, the axial positioning block 13 is inserted into the groove 14 between the transmission rod 7 and the drive rod 15, and the bolt 12 is threadedly inserted into the axial positioning block 13, so that the transmission rod 7 and the drive rod 15 remain fixed. When there is no product on the conveyor belt 2, unscrew the bolt 12 and remove the axial positioning block 13, so that the drive rod 15 remains fixed during the rotation of the drive rod 7, thereby avoiding the situation where there is no product on the conveyor belt 2 and the ink is continuously extruded.
