[0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. In the production process of existing fabrics, it is often necessary to print the fabrics. For example, a polyester filament invisible fabric printing device with publication number CN207789986U prints the fabric through a printing roller. However, the printing roller of the patent (that is, the printing roller body of the present invention) is an integrated type. When the roller surface of the printing roller is damaged, the entire printing roller needs to be replaced, which is relatively wasteful. Utility Model Content

[0003] The utility model aims to solve the technical problem of providing a printing roller group in which a printing shell can be replaced separately when the roller surface of the printing roller body is damaged.

[0004] In order to solve the above technical problems, the technical solution of a printing roller group for wrinkled fabrics in the present invention is:

[0006] The upper and lower sides of both ends of the printed shell are provided with mounting grooves, and the upper and lower sides of the corresponding side covers are connected with plug-in blocks.

[0007] Both sides of the insertion rod are provided with transverse sliding grooves; the two sides of the interior of the printing shell are respectively connected to transverse sliding rails corresponding to the two transverse sliding grooves; the insertion rod is transversely slidably connected to the two transverse sliding rails through the two transverse sliding grooves and is slidably connected to the printing shell.

[0008] The side covers are connected to the printed shell by two connecting bolts; the bottom ends of the two connecting bolts pass through the side covers and are respectively threadedly connected to the two horizontal slide rails.

[0009] There are longitudinal sliding grooves on both sides of the frame; longitudinal sliding rods are connected to the longitudinal sliding grooves; one end of the longitudinal sliding rod passes through the frame and is connected to a rotating head, and the other end is threadedly connected to the frame; the two longitudinal sliding rods are longitudinally slidably connected to a shaft; a pressure roller is rotatably connected to the shaft; springs are mounted on the longitudinal sliding rods; the pressure roller is pressed on the extrusion roller by the spring.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] See Figures 1 to 10 .

[0026] A printing roller group for wrinkled fabrics includes a frame 1 and a printing roller body and an extrusion roller 2 rotatably connected to the frame 1. The printing roller body includes a printing shell 3, a rotating connecting shaft 4 and two side covers 5. The middle part of the rotating connecting shaft 4 is connected to a plug rod 6 that is plugged into the printing shell 3. The rotating connecting shaft 4 is inserted into the printing shell 3 through the plug rod 6 and is horizontally slidably connected to the printing shell 3; specifically, horizontal slide grooves 11 are provided on both sides of the plug rod 6, and horizontal slide rails 12 corresponding to the two horizontal slide grooves 11 are respectively connected on both sides of the interior of the printing shell 3. The plug rod 6 is horizontally slidably connected to the two horizontal slide rails 12 through the two horizontal slide grooves 11 and is slidably connected to the printing shell 3.

[0027] Both ends of the printed shell 3 are provided with mounting grooves 7; both ends of the insertion rod 6 are respectively provided with insertion holes 8 corresponding to the mounting grooves 7; a limit rod 9 is placed in the mounting groove 7, and the lower end of the limit rod 9 passes through the printed shell 3 and is inserted into the insertion hole 8; the two side covers 5 are respectively connected to the plug-in blocks 10 corresponding to the mounting grooves 7 at both ends of the printed shell 3, and the plug-in blocks 10 are inserted into the mounting grooves 7 corresponding to themselves, and limit the limit rod 9 so that the limit rod 9 cannot be loosened from the insertion hole 8; specifically, mounting grooves 7 are opened on the upper and lower sides of both ends of the printed shell 3, and the corresponding side covers 5 are connected with plug-in blocks 10 on the upper and lower sides.

[0028] The two side covers 5 are detachably connected to both ends of the printed shell 3; specifically, the side covers 5 are connected to the printed shell 3 through two connecting bolts 13; the bottom ends of the two connecting bolts 13 pass through the side covers 5 and are respectively threadedly connected to the two horizontal slide rails 12.

[0029] The printing roller body of the present invention comprises a printing shell 3, a rotating connecting shaft 4 and two side covers 5; after the outer surface of the printing roller body is damaged (that is, after the outer surface of the printing shell 3 is damaged), the two connecting bolts 13 on the side cover 5 can be unscrewed first, and then the side cover 5 can be removed. At this time, the plug-in block 10 is disengaged from the mounting groove 7, and the limiting rod 9 is not limited. Then the limiting rod 9 is taken out from the mounting groove 7. At this time, the printing shell 3 can be directly removed from the plug-in rod 6, so as to be replaced, which is more convenient; compared with the existing integrated design of the printing roller body, the present invention only needs to replace the printing shell 3 after the outer surface of the printing roller body is damaged.

[0030] In the connection of the rotating connecting shaft 4, connecting grooves are respectively opened on both sides of the upper part of the frame 1 of the present invention; the two ends of the rotating connecting shaft 4 are respectively placed on the two connecting grooves and limited by the limit cover 31, the limit cover 31 is connected to the frame 1 by bolts, and the rotating connecting shaft 4 is rotatably connected to the connecting groove; therefore, the rotating connecting shaft 4 of the present invention can also be disassembled on the frame 1. When disassembling, it is only necessary to unscrew the bolts between the limit cover 31 and the frame 1, and then the rotating connecting shaft 4 and the limit cover 31 can be removed.

[0031] A longitudinal slide groove 21 is provided on both sides of the frame 1, and a longitudinal slide rod 22 is connected to the longitudinal slide groove 21; one end of the longitudinal slide rod 22 passes through the frame 1 and is connected to the rotating head 23, and the other end is threadedly connected to the frame 1; the two longitudinal slide rods 22 are longitudinally slidably connected to the shaft body 24, specifically, both ends of the shaft body 24 are connected to sliders 27, and the two sliders 27 are longitudinally slidably connected to the two longitudinal slide rods 22 respectively; a pressure roller 25 is rotatably connected to the shaft body 24, and a spring 26 is provided on the longitudinal slide rod 22, and the pressure roller 25 is pressed on the extrusion roller 2 by the spring 26.

[0032] The utility model also provides a pressing roller 25 on the frame 1 for flattening wrinkled fabrics. Specifically, the pressing roller 25 is pressed on the squeezing roller 2 by a spring 26. When the wrinkled fabric passes between the squeezing roller 2 and the pressing roller 25, the squeezing roller 2 and the pressing roller 25 squeeze the wrinkled fabric and flatten the wrinkled fabric. The flattened wrinkled fabric is then sent between the printing roller body and the squeezing roller 2 for printing, and the printing effect is better. In addition, in the utility model, since the longitudinal slide rod 22 is threadedly connected to the frame 1, when the longitudinal slide rod 22 needs to be disassembled, the rotating head 23 is rotated by a hexagonal wrench to rotate the longitudinal slide rod 22, thereby unscrewing the longitudinal slide rod 22 from the frame 1.
