Description

Technical Field

[0001] This utility model relates to the field of inkjet printing cloth technology, specifically to an inkjet printing cloth conveying and positioning structure. Background Technology

[0002] Printed fabric, commonly known as lightbox fabric, is a printing material made from PVC through a specific manufacturing process. It is mainly used for outdoor advertising printing.

[0003] Chinese Patent No. CN218057814U discloses a printing cloth conveying and positioning structure, specifically relating to the field of printing cloth conveying. This invention includes a conveyor belt and a base frame. A leveling device is provided at one end of the top of the base frame, and a cleaning device is provided at the end of the top of the base frame away from the leveling device. The leveling device includes a U-shaped frame, the bottom of which is fixedly connected to the top of the base frame. A rectangular groove is formed on the inner wall of the U-shaped frame, and a threaded rod is provided on the inner wall of the rectangular groove. The threads at both ends of the threaded rod are in opposite directions, and a slider is symmetrically threaded onto the outer surface of the threaded rod. When the printing cloth wrinkles and overlaps due to external force, a pressure plate presses the printing cloth onto the conveyor belt. The threaded rod drives the slider to slide in the rectangular groove, thereby driving an electric telescopic rod to slide the pressure plate, thus pressing and flattening the wrinkles of the printing cloth from the center of the conveyor belt outwards.

[0004] However, in the above technical solution, the slider is driven by the threaded rod to slide in the rectangular groove, thereby driving the electric telescopic rod to drive the pressure plate to slide. This allows the folds of the inkjet cloth to be pressed and flattened from the center of the conveyor belt to both sides. However, when this structure is used, the pressure plate pressing down and contacting the folds may cause the folds to be overstretched, resulting in deformation or breakage that is difficult to recover.

When the leveling assembly is in use, the telescopic device 2 drives the movable frame 3 and the smoothing roller 4 closer to the inkjet fabric. The moving end of the moving component drives the smoothing roller 4 to move horizontally, smoothing wrinkles on the inkjet fabric. The cleaning assembly is connected to the belt conveyor and is located upstream of the leveling assembly. When the cleaning assembly is in use, the cleaning end of the cleaning assembly scrapes against the surface of the inkjet fabric moving with the belt conveyor.

[0025] Example 2

[0026] like Figures 1-2 As shown, this utility model proposes a printing cloth conveying and positioning structure. Compared with Embodiment 1, this embodiment describes the detailed structure of the leveling component.

[0027] The moving parts include a second drive device 9, a coaxial bidirectional screw 10, an auxiliary rod 11, and a sliding block 12. The second drive device 9 is connected to the mounting top plate 8. The second drive device 9 may be, but is not limited to, a motor. One end of the coaxial bidirectional screw 10 is connected to the sliding groove, and the other end of the coaxial bidirectional screw 10 passes through the mounting top plate 8 and is connected to the second drive device 9. Two auxiliary rods 11 are symmetrically arranged, and both ends of the auxiliary rods 11 are connected to the sliding groove. Two sliding blocks 12 are symmetrically arranged, and the sliding blocks 12 are provided with threaded holes and through holes corresponding to the coaxial bidirectional screw 10 and the auxiliary rod 11.

[0028] In an optional embodiment, the smoothing roller 4 is provided with a fixed ring 13 and a movable ring 14 at both ends. The fixed ring 13 has multiple limiting grooves that accommodate one end of the scraper 6. The movable ring 14 has multiple sliding grooves that cooperate with the other end of the scraper 6. The movable ring 14 has a threaded hole and a threaded rod 15 is connected inside the threaded hole. One end of the threaded rod 15 passes through the movable frame 3 and is connected to a handle 16.

One end of the movable ring 14 has a sliding groove and can rotate synchronously with the smoothing roller 4. The other end of the movable ring 14 can move horizontally to adjust the distance between the movable ring 14 and the scraper 6.

[0029] Example 3

[0030] like Figures 1-2As shown, this utility model proposes a printing cloth conveying and positioning structure. Compared with Embodiment 2, this embodiment describes the detailed structure of the cleaning component. The cleaning component includes a mounting base 17, an adjusting screw 18, an adjusting handle 19, a guide rod 20, a guide block 21, a mounting plate 22, and a brush 23. Two mounting bases 17 are symmetrically arranged and connected to a belt conveyor. Each mounting base 17 has a receiving cavity on one side facing each other. The adjusting screw 18 is rotatably connected to either mounting base 17. One end of the adjusting screw 18 passes through the mounting base 17 and connects to the adjusting handle 19. A moving block is connected to the adjusting screw 18. The guide rod 20 is connected to the mounting base 17 and the guide block 21 is connected to the guide rod 20. Both ends of the mounting plate 22 are connected to the guide block 21 and the moving block, respectively. The brush 23 is detachably connected to the mounting plate 22.

[0031] In an optional embodiment, the bristles of the cleaning brush 23 are designed with a gradient, and the hardness of the bristles gradually increases from the feed end to the discharge end.

[0032] In an optional embodiment, the mounting plate 22 is provided with a plurality of dovetail grooves 24, and the cleaning brush 23 is connected with a dovetail block 25 that is slidably connected to the dovetail grooves 24; the dovetail grooves 24 are not through structures, and can be removed directly from one side, and due to their orientation, they can remain fixed when subjected to external force.

[0033] In an optional embodiment, the scraper 6 comprises at least two material segments of different materials, which are arranged alternately; the different materials give it different properties, enabling it to maintain normal operation after the rubber and silicone scraper 6 are worn.

[0034] In summary, when using this utility model, the inkjet cloth is conveyed from the belt conveyor to a certain point and then stopped automatically or manually. The telescopic device 2 and the first drive device 5 are then activated. The telescopic device 2 drives the moving frame 3 and the smoothing roller 4 closer to the inkjet cloth. The first drive device 5 drives the smoothing roller 4 to rotate its multiple scrapers 6. Simultaneously, the second drive device 9 drives two sliding blocks 12 and the telescopic device 2 to move in opposite directions horizontally via a coaxial bidirectional screw 10. During this movement, the scrapers 6 on the smoothing roller 4 pull the inkjet cloth in the middle position outwards by rotation, thus unfolding the stacked and wrinkled inkjet cloth and preventing it from affecting subsequent work. When it is necessary to replace the scrapers 6, the screw rod 15 can be moved by adjusting the handle 16, causing the moving ring 14 to move, thereby removing and replacing the scraper 6.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
