Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 - Figure 6 As shown, a combined composite tissue printing roller includes a main printing roller 1, the main printing roller 1 is fixedly connected to a fixed shaft 20, a clamping mechanism is arranged inside the fixed shaft 20, the clamping mechanism includes a through groove 22, the through groove 22 communicates with a cavity 25, the cavity 25 is opened inside the fixed shaft 20, a clamping block 27 is slidably connected inside the through groove 22, the clamping block 27 is clamped on the inner wall of the mounting roller 21, the clamping block 27 is fixedly connected to a connecting block 32, the connecting block 32 is designed in an L shape, there are two groups of the connecting blocks 32, a support spring 29 is fixedly connected between the two groups of the connecting blocks 32, a slider 31 is fixedly connected to the connecting block 32, the slider 31 is slidably connected inside a sliding groove 23, the sliding groove 23 is opened on the inner wall of the cavity 25, an abutting block 30 is fixedly connected to the connecting block 32, the abutting block 30 is close to a movable block 35, the movable block 35 is slidably connected inside the cavity 25, the movable block 35 is fixedly connected to a connecting rod 36, one side of the connecting rod 36 away from the movable block 35 is fixedly connected to a connecting plate 43, and the connecting plate 43 is rotatably connected to a long rod 37;

[0025] Through the structural design of the clamping mechanism, the function of facilitating the assembly of different mounting rollers 21 on the printing main roller 1 is realized, so as to cooperate with the printing main roller 1 to print different patterns, and thus there is no need to replace the printing main roller 1. During operation, the mounting roller 21 is attached to one side of the printing main roller 1, and a slot corresponding to the clamping block 27 is provided on the inner wall of the mounting roller 21. When the clamping block 27 is inserted into the inner wall of the mounting roller 21, the mounting roller 21 can be fixed on the printing main roller 1. Since two sets of mounting rollers 21 are assembled on the left and right sides of the printing main roller 1, different patterns can be printed. When the mounting roller 21 needs to be replaced, first, by pulling the long rod 37, the connecting plate 43 rotatably connected to the long rod 37 will pull the connecting rod 36, and then the connecting rod 36 will pull the movable block 35 to slide inside the cavity 25. A slideway corresponding to the connecting rod 36 is provided on the inner wall of the cavity 25 to facilitate the normal sliding of the connecting rod 36 inside the cavity 25. The movable block 35 is close to the abutting block 30, so it will abut against the abutting block 30 during the sliding process, thereby pushing the two connecting blocks 32 to both sides. The supporting springs 29 connected to the two connecting blocks 32 will be stretched. When the connecting block 32 slides inside the cavity 25, the clamping block 27 fixed on the connecting block 32 will gradually separate from the inner wall of the mounting roller 21 and finally release the fixation of the mounting roller 21. At this time, the mounting roller 21 can be removed from the printing main roller 1 along the direction of the fixed shaft 20, thus facilitating the replacement of the mounting roller 21. A slider 31 is fixed on the connecting block 32, and the sliding of the slider 31 inside the chute 23 is used to limit the moving distance of the connecting block 32 inside the cavity 25 and also prevent the connecting block 32 from sliding out of the cavity 25.

[0026] Further, a fixing component is provided on the connecting plate 43. The fixing component includes four sets of insertion posts 33, and the insertion posts 33 are inserted into the card slots 28. The card slots 28 are opened on one side of the connecting block 32.

[0027] Through the structural design of the fixing component, the function of fixing the two connecting blocks 32 is realized, ensuring that the positions of the two connecting blocks 32 inside the cavity 25 can be kept fixed, and avoiding that when the connecting block 32 is in a vertical state, the connecting block 32 will slide downward under the action of gravity, resulting in a poor fixing effect between the clamping block 27 and the mounting roller 21. During operation, since the abutting block 30 is close to the movable block 35 and does not contact the movable block 35 in the initial state, when the long rod 37 pulls the connecting plate 43 to move, the four sets of insertion posts 33 fixed on the connecting plate 43 can be smoothly pulled out of the card slots 28. At this time, when the long rod 37 is continuously pulled, the movable block 35 will abut against the abutting block 30 and push the two connecting blocks 32 to move. By inserting the insertion posts 33 into the card slots 28, the positions between the two connecting blocks 32 can be fixed, ensuring that the positions of the connecting blocks 32 inside the cavity 25 will not move, and further ensuring the fixing effect of the clamping block 27 on the mounting roller 21.

[0028] Further, the long rod 37 is slidably connected inside the long groove 26. The long groove 26 is opened inside the fixed shaft 20. The long groove 26 communicates with the cavity 25. An installation block 38 is fixedly connected to the long rod 37. Threads are provided on the installation block 38. The installation block 38 is threadedly connected to the inner wall of the long groove 26;

[0029] During operation, the long rod 37 slides inside the long groove 26. An installation block 38 is also fixedly connected to the long rod 37. A groove is provided on the installation block 38 to facilitate screwing it. And the installation block 38 is threadedly connected to the inner wall of the long groove 26, so as to fix the position of the long rod 37 inside the long groove 26.

[0030] Further, the movable block 35 is trapezoidally designed. Two groups of connecting springs 34 are fixedly connected to the side of the movable block 35 away from the long rod 37. The side of the connecting spring 34 away from the movable block 35 is fixedly connected to the inner wall of the cavity 25;

[0031] During operation, the movable block 35 is trapezoidally designed to facilitate abutting against the abutting block 30. Two groups of connecting springs 34 are fixedly connected to the movable block 35. When the connecting rod 36 pulls the movable block 35 to move, the two groups of connecting springs 34 will be stretched, thereby providing resistance for pulling the long rod 37.

[0032] Further, a plurality of limiting grooves 41 are opened on the inner wall of the mounting roller 21. The limiting grooves 41 are slidably connected to the limiting strips 42. The limiting strips 42 are fixedly connected to the fixed shaft 20;

[0033] During operation, the limiting grooves 41 opened on the inner wall of the mounting roller 21 are slidably connected to the limiting strips 42. When installing the mounting roller 21, the mounting roller 21 can be smoothly installed on the fixed shaft 20 by aligning the limiting grooves 41 with the limiting strips 42. At the same time, the connection strength between the fixed shaft 20 and the mounting roller 21 is improved by the abutting between the limiting strips 42 and the inner walls of the limiting grooves 41. Among them, the limiting grooves 41 are not circumferentially distributed on the inner wall of the mounting roller 21, which can ensure that the position of the mounting roller 21 can be accurately installed in place.

[0034] Further, a plurality of positioning grooves 39 are opened on both the left and right sides of the printing main roller 1. A positioning column 40 is inserted into the positioning groove 39. The positioning column 40 is fixedly connected to one side of the mounting roller 21;

[0035] During operation, the positioning column 40 fixed on the mounting roller 21 is inserted into the positioning groove 39. The connection strength between the mounting roller 21 and the printing main roller 1 can be improved through the abutting between the inside of the positioning groove 39 and the positioning column 40, ensuring that there is no relative sliding between the printing main roller 1 and the mounting roller 21.

[0036] Working principle: Through the structural design of the clamping mechanism, the function of facilitating the assembly of different mounting rollers 21 on the printing main roller 1 is realized, so as to cooperate with the printing main roller 1 to print different patterns, and thus there is no need to replace the printing main roller 1. During operation, the mounting roller 21 is attached to one side of the printing main roller 1, and a slot corresponding to the clamping block 27 is provided on the inner wall of the mounting roller 21. When the clamping block 27 is inserted into the inner wall of the mounting roller 21, the mounting roller 21 can be fixed on the printing main roller 1. Since two sets of mounting rollers 21 are assembled on the left and right sides of the printing main roller 1, different patterns can be printed. When the mounting roller 21 needs to be replaced, first, by pulling the long rod 37, the connecting plate 43 rotatably connected to the long rod 37 will pull the connecting rod 36, and then the connecting rod 36 will pull the movable block 35 to slide inside the cavity 25. A slideway corresponding to the connecting rod 36 is provided on the inner wall of the cavity 25 to facilitate the normal sliding of the connecting rod 36 inside the cavity 25. The movable block 35 is close to the abutting block 30, so it will abut against the abutting block 30 during the sliding process, thereby pushing the two connecting blocks 32 to both sides. The support springs 29 connected to the two connecting blocks 32 will be stretched. When the connecting blocks 32 slide inside the cavity 25, the clamping blocks 27 fixed on the connecting blocks 32 will gradually separate from the inner wall of the mounting roller 21 and finally release the fixation of the mounting roller 21. At this time, the mounting roller 21 can be removed from the printing main roller 1 along the direction of the fixed shaft 20, thus facilitating the replacement of the mounting roller 21. A slider 31 is fixed on the connecting block 32, and the sliding of the slider 31 inside the chute 23 is used to limit the moving distance of the connecting block 32 inside the cavity 25 and also prevent the connecting block 32 from sliding out of the cavity 25.

[0037] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
